Current Circumstances: The City Council must make a determination whether or not the project has "significant environmental effects" which requires that an EA W be prepared. Minnesota Statute lays out the criteria that the City must use in deciding whether to require an EA W. Those criteria are as follows: -.- A. type, extent, and reversibility of environmental effects; B. cumulative potential effects of related or anticipated future projects; C. the extent to which the environmental effects are subject to mitigation by ongoing public regulatory authority; and D. the extent to which environmental effects can be anticipated and controlled as a result of other environmental studies undertaken by public agencies or the project proposer or of EIS's previously prepared on similar projects. As set forth in the Environmental Assessment Worksheet handbook prepared by the Environmental Quality Board (EQB), "the rules require only that the RGU (Responsible Governmental Unit) [in this case, Prior Lake] consider all known evidence, compare that evidence to the standard 'there may be potential for significant environmental effects' and document the findings and decision in writing". (Step 3, page 8, Guide to Environmental Assessment Worksheets, previously provided to the Council). The Issues: The basis for the petition is set out in a letter accompanying the petition for an EA W from Attorney Gregory A. Fontaine, on behalf of Dorsey & Whitney LLP, to the EQB dated January 14,2000. Minnesota rules require "petitioners must present a case for why the project should have an EA W prepared even though it does not exceed mandatory thresholds, by documenting unusual features relating to its nature or location. Material evidence can take many forms-maps, site plans, existing reports, letters from experts, testimonial letters from citizens, photographs, etc.- but it must be a factual documentation of potential for significant environmental effects. To be successful. petitioners must do more than express their 011 position or raise questions and concerns" (emphasis added). (Step 1, Page 7 Guide to Environmental Assessment Worksheets referencing Minnesota Statutes 4410.1100). The petitioner's January 14,2000 letter and the petition does not contain any factual documentation or information as required by Minnesota Rule 4410.1100 which, in the staff's opinion, would sustain their rationale that EA W must be prepared. For example, the 1:\99fi1es\99cup\99-075\99-075c I.doc Page 2 --' , ~~ _J, ~~ t)~ ~?, oJ' ~ \)~ ~11 ~1f- "\ petitioner expresses concerns (not factual information) regarding traffic congestion, safety, infrastructure impacts, quality of drinking water, natural features, dust, noise, and aesthetic impacts and restoration. The principal basis the petitioner relies on to indicate that the City should require an EA Ware: 1. Ryan is attempting to avoid environmental review by improperly segmenting the project to fall below the 40-acre threshold for mandatory EA W. 2. Potential traffic .safety hazards and congestion on CSAH 42 and McKenna Road. 3. Potential interference with the drinking water resources of the Shakopee Mdewakanton Sioux Community (SMSC). 4. Potential impacts to Boiling Springs and the Savage Fen. 5. Other possible environmental impacts on surrounding communities. Each claimed basis for preparing an EA W is addressed below: 1. 40 Acre Mandatory EA W The petitioner claims an EA W is mandatory because the site exceeds 40 acres. According to Minnesota Rules, an EA W is mandatory if more than 40 acres is being mined. Ryan is mining 12.91 acres of the 29.6 acres site. Based on soil borings taken by Ryan, the soils surrounding the 12.91-acres are not suitable for mining. The CUP limits the location ofthe mining to the 12.9l-acre site plan submitted. Since the mining area is less than 40 acres, an EA W is not mandatory. In response to the petitioners concern, a condition specifically limiting Ryan to the proposed 12.91 acres has been added to the resolution. 2. Traffic: Page 12 of the EA W Guide, a guide to assist in completing an EA W, states "The form asks whether potential land use conflicts involve environmental matters because not all land use conflicts do- e.g. heavy truck traffic from a gravel mine near a residential area may cause land use conflict due to safety concerns but this is not an environmental matter. The EQB rules define "environment" to include: land, air, water, minerals, flora, fauna, ambient noise, energy resources, and man-made objects or natural features of historic, geologic, or aesthetic significance(4410.0200, subp. 23)." Therefore, the argument the petitioner makes regarding traffic does not rise to the level of a "significant environmental effect" or is not an environmental concern as defined by the EQB. For information to the Council, staffis providing a review of the petitioners concerns related to traffic as follows: 1:\99fi1es\99cup\99-075\99-075c 1.doc Page 3 ..- - no "T T -~- A. Traffic-Congestion and Disruption: The petitioner claims the project will increase traffic levels and cause congestion and disruption on McKenna Road and CSAH 42. The petitioner claims there will be 17 to 50% increase in traffic on McKenna Road and disruption to traffic on CSAH 42. The petition suggests traffic has not been reviewed by the City. The petition does not contain any factual evidence, as required by Minnesota rules 4410.1100, to support its conjecture that there will be a 17-50% increase in traffic on McKenna Road. However, logic supports an assumption that Ryan's operation will generate increased use of McKenna Road. Ryan estimates an average of 6 trips per hour of operation. The 2010 Comprehensive Plan indicates a 1995 average of 400 trips per day on McKenna Road just north of CSAH 42. In addition, the 2020 Comprehensive Plan states two-lane rural roads have a maximum capacity of 14,000-15,000 vehicle trips per day, or 900 trips per lane per hour. Therefore, the estimate provided by Ryan (or even ten times the estimate if it is considerably underestimated) will not cause a significant increase or congestion in traffic as determined by the maximum capacity ofthe roadway. To reiterate, the petition must contain material evidence consisting of factual documentation of potential for significant environmental effects in lieu of expressing opinions or raising concerns alone. In response to the petitioners concerns, a condition limiting the truck route from the pit directly south on McKenna Road to CSAH 42, as originally proposed by Ryan, has been added to the resolution. B. Safety The petitioner claims McKenna Road is the main access to a residential development to the north that contains 45+ homes and that the expected truck traffic from the Ryan site will interfere with the safety of the residential development. While McKenna Road is a main access to CSAH 42 from this neighborhood, it is designated as a collector street. Other collector streets in the City include Wilds Parkway, Fish Point Road, Pike Lake Trail, Carriage Hills Parkway, and Franklin Trail. Ingress and egress to and from a facility such as the one proposed for the Ryan site are appropriately located on a collector street. Collector streets are intended to provide entire neighborhoods with access to arterial roadways. Based on the petitioner's numbers, the petitioner suggests the operation on the Ryan site will generate from 68 to 200 additional trips per day. The petition offers no factual basis to support its statement. Ryan Contracting estimates an average of 6 trucks hauling per hour of operation. Utilizing a round trip, this results in 120 trips per 10 hours of operation per day. 1:\99fi1es\99cup\99-075\99-07 5c 1.doc Page 4 ~~d v-e.)~~ - ~,~- '1~ ~~l/ (}~"'-...\~~~ ~~. ~" A typical residential neighborhood generates a majority of its trips during certain peak hours, generally 7 a.m. to 9 a.m. and 4 p.m. to 6 p.m.. Staff has no specific data on McKenna Road to verify this. It is a general assumption based on typical work hours of residents in a residential neighborhood. At the January 18,2000 City Council meeting, Councilmembers Schenck and Gundlach suggested limiting the hours of operation from 8 a.m. to 5 p.m. weekdays only. Should the Council choose to alter the resolution as presented and recommended by the staff and Planning Commission to limit the hours as most recently proposed, there is a rational basis for doing so. The hours of operation (8 a.m. to 5 p.m. weekdays) will result in fewer trucks hauling (96 trips per day) generally during non-peak hours (72 trips) mitigating safety concerns arising from increased traffic, since 24 trips would be expected to occur during peak hours. C. Infrastructure Impacts 1). The petitioner states no information has been provided regarding the impact of the operation on the structural capacities of McKenna Road and CSAH 42 and is concerned about the condition of McKenna Road particularly that portion running northerly into Shakopee and CSAH 42. The petition does not contain any factual evidence, as required by Minnesota rules 4410.1100, to support its conjecture that Ryan's operation will cause accelerated degradation of McKenna Road. However, this possibility has been anticipated by the City and conditions have been placed in the CUP to assure the financial responsibility for any impacts to McKenna Road are borne by Ryan. One of the conditions of approval in the CUP requires Ryan to provide the City with an irrevocable letter of credit for the ongoing maintenance and repair of McKenna Road should the applicant fail to make required improvements. The applicant is responsible for maintaining the current condition of the road. The City is aware of the current condition and has inspected its condition. The condition will be documented by the City prior to Ryan beginning work (photos, written inspection). As far as truck traffic on McKenna Road into Shakopee, truck traffic will not be traveling north into Shakopee. As a response to the petitioners concerns, this truck route has been made a specific condition of the CUP resolution. Additionally, per the 2020 Comprehensive Plan, the southern portion of McKenna Road is proposed to be realigned to the east and the existing roadway abandoned. 1:\99fi1es\99cup\99-075\99-07 5c I.doc .unoT Page 5 T T 2). The petitioner further alleges the City of Shakopee may not have been sent a notice. The City of Shakopee was sent a public hearing notice and no written comments were received. However, the City Engineer of Shakopee verbally expressed concern regarding truck traffic on the Shakopee portion of McKenna Road. As previously noted, a condition of the CUP prohibits truck traffic from the proposed gravel pit north on McKenna Road into Shakopee. Regarding CSAH 42, the City sent the County Highway Department a notice. Their only recommendation was that Ryan be responsible for clean up of gravel. -.' 3. Water Resources A. Drinking Water protection-The petitioner states the proposed project could negatively affect the quality of drinking water. If Ryan installs their own water supply well, the quality of water of the SMSC water supply well could be affected. Ryan Contracting is not installing a water supply well for use in the mining operation. The petitioner is incorrect in making the assumption a water supply well will be installed and utilized as a part of the operation. The petitioner has not provided information as to support any negative effects ofthe existing mining operation located directly to the north has on their water supply to support any argument that Ryan's mining would have a negative impact. Staffhas contacted the Department of Health regarding groundwater / effects. The Department of Health has no specific regulations , regarding separation between the bottom of the pit and the aquifer. They make recommendations that no fuel be stored on site and that a gate controlling the site be installed. There will be no on site fuel storage and a gate or fence must be installed prior to beginning work as stated in the conditions of approval. The petitioner has provided a map showing that the proposed gravel pit lies within the SMSC well head- Source Water Assessment Area (10- year time oftravel zone). To date, the City has not had any discussions with the SMSC regarding their well head protection plan for this area and what action would be required by the City in the execution of their protection plan. Staff feels the controls imposed on Ryan, i.e. no water supply wells or fuel storage on the site, provide significant control over a fuel spill which could have a significant impact on the SMSC water supply well. Fuel spills or other contaminant spills can happen anywhere, anytime, and could affect many wells within the City. However, these City imposed controls are a reasonable deterrent to a spill happening within Ryan's proposed pit. To be sensitive and responsive to the petitioners concerns, staff is recommending that a condition be added to the resolution regarding Ryan's CUP that prohibits the installation ofa water supply well as a 1:\99fi1es\99cup\99-07 5\99-075c 1.doc Page 6 source for water on site and requires the installation of a monitoring well with ongoing testing to assure a degradation in the quality of water does not occur. Staff contacted a consulting engineer to determine what potential problems might stem from the existence of an observation well on the site. The consultant indicated they had been involved with the placement and monitoring of such wells since the 1960's and could not recall an instance when such wells had been vandalized. He also could not recall an instance when ground water contamination had occurred because of an observation well. He further indicated there are heavy duty locking devices available for such wells which provide more security than a padlock. Such a device could be specified as a condition of the resolution for the conditional use permit. Ryan will be using only water from off-site sources for dust control. The resolution makes this point very clear. -~' B. Additionally, the petitioner states the CUP would allow a water supply well with pumping of up to 10,000 gallons per day or 1 million gallons per year and lists specific concerns related to such a well. This statement is incorrect. The CUP prohibits Ryan's project from having a water supply well. Additionally, a DNR permit is required for pumping of more than 10,000 gallons per day or 1 million gallons per year. Dewatering could occur ifthe ground water levels at the site are at a higher elevation than the excavation. The removal of this water will require a DNR permit ifthe limits above are exceeded as mentioned in the comments received from Pat Lynch, Area Hydrologist for the DNR, dated October 18, 1999. 4. The petitioner is concerned about the Boiling Springs and Savage Fen. These natural features are controlled by the DNR. The petitioner has offered no factual evidence, as required by Minnesota rules 4410.1100, to support its conjecture that Boiling Springs or Savage Fen will be adversely affected by the proposed excavation of sand and gravel at this location. The City had referred the project for review by the DNR. The DNR made no initial mention of either of these two features. After the EA W petition was filed, the City received an internal memorandum from the DNR dated January 18,2000. The memo states the pit is on 50 acres and there are wells proposed. The author suggests there may be an impact and additional infonnation and time for review is suggested. Considering the gravel operation itself is 12.91 acres and no water supply well is proposed, the comments appear to be based on misleading or inaccurate infonnation. The author of the memo also states the pit is close to Prior Lake's PWS (public Water Supply). This too is an incorrect statement. This area is outside of the City's wellhead assessment area. The City has yet to adopt a well head protection plan. 1:\99fi1es\99cup\99-075\99-075c I.doc Page 7 .-------rr-T .. T T Furthermore, Scott County and the City of Shakopee were sent notice ofthe project and offer no comments or concerns about these natural features being adversely affected. As mentioned earlier, the DNR does require permitting for pumping groundwater at or above certain levels. This permitting process would warrant further review by the DNR that could possibly include analysis ofthe Boiling Springs and Savage Fen. Attached are maps indicating the surface watershed boundaries. In both cases, the watershed boundaries are outside the City limits and outside the proposed excavation area. Considering no water supply well will be drilled to provide water for use for the operation or on the site, there will be no additional exposure to the Jordan aquifer, the Boiling Springs or the Savage Fen. 5. Impacts on Neighboring Communities- The petitioner lists specific effects and suggests an EA W could identify options to eliminate or substantially mitigate them. The petition does not contain any factual evidence, as required by Minnesota rules 4410.1100, to support its conjecture that there are potential environmental impacts on neighboring communities. Each of the concerns identified by the petitioner were identified by staff in an analysis of Ryan's application and Ryan's submittals and are stated in the previous staffreports. Staff feels that the conditions imposed in the CUP address the petitioners concerns. A. Dust-The petitioner has failed to provide any factual information regarding any potential environmental impact from dust, but rather states a concern that the issue has not been fully addressed. Ryan proposes to water the roadways with a calcium chloride solution to minimize dust on an as needed basis. As a condition ofthe CUP Ryan will be required to apply water for dust control within 24 hours of notice from the City Engineer. The watering will take place on the entire site in order to mitigate any dust problem. The berm on the west side of the excavation area is a part of Phase 1 and eventually a berm will surround the entire area under excavation. Tab 21, of Exhibit A Ryan's Project Plan Book (CUP application), details the proposal for containing dust. B. Noise-The petitioner states that noise will adversely affect the neighborhood and no mitigative measures have been taken. The Planning Commission recommended hours of operation be limited and members of the City Council have suggested further restricting the hours of operation to 8 a.m.-5 p.m. With these limitations, the impacts of noise have been mitigated and remain reasonable. The proposed project is located on property owned by private residents. Ifthey objected to the proposed noise, and they are the closest residents to the 1:\99fi1es\99cup\99-075\99-075c 1.doc Page 8 site, they would not have entered into an agreement with Ryan. The nearest house (other than the property owners) is approximately 325 feet to the south. Furthermore, the proposed operation includes mining and screening only. There will be no crushing operation. Ryan will operate within noise requirements established by the Minnesota Pollution Control Agency. The City cannot impose more stringent standards than those established by the PCA. Tab 20, of Exhibit A Ryan's Project Plan book (CUP application), contains a detailed analysis of decibel levels predicted and allowable levels. The Ryan proposal meets these requirements. -.- C. Aesthetic Impacts and Restoration- the petitioner is concerned about the future development of this property and the proposed reclamation plan. The property is currently zoned Agricultural. The Comprehensive Plan designates the property as Low/Medium Density Residential. The property owners have indicated their future use is agricultural. When excavation is completed, the final grades will be consistent with current standards of those allowed under the Subdivision Ordinance for a residential subdivision (3: 1 slope maximum). Conclusion: Minnesota rules require "petitioners must present a case for why the project should have an EA W prepared even though it does not exceed mandatory thresholds, by documenting unusual features relating to its nature or location. Material evidence can take many forms-maps, site plans, existing reports, letters from experts, testimonial letters from citizens, photographs, etc.- but it must be a factual documentation of potential for significant environmental effects. To be successful, petitioners must do more than express their opposition or raise questions and concerns". (Step 1, Page 7 Guide to Environmental Assessment Worksheets referencing Minnesota Statutes 4410.1100). The petition does not contain any factual information as required by Minnesota Rules 4410.1100 relating to potential environmental impacts. Rather, the petition expresses concern regarding traffic congestion, safety, infrastructure impacts, quality of drinking water, natural features, dust, noise, and aesthetic impacts and restoration. Therefore, staff recommends denial of the petition to require an EA W for the excavation of sand and gravel as proposed by Ryan Contracting. Should the City Council order an EA W, the result will be the following: The EA W will determine ifthere are significant environmental impacts. The EA W will result in recommendation of conditions to impose on the project. The EA W will result in a 1:\99fi1es\99cup\99-075\99-075c I.doc Page 9 I I T recommendation whether to require an Environmental Impact Statement (EIS) or not. Ultimately, the EA W or EIS will not prohibit the project, but rather identify potential environmental impacts and allow the opportunity to define and require mitigating measures. Section 1108.201, the Zoning Ordinance identifies certain uses, which because of their nature, operation and location in relation to other uses require a CUP. The CUP process regulates the location, magnitude and design of conditional uses consistent with the Comprehensive Plan, and the regulations, purposes and procedures ofthe Zoning Ordinance. -.- CUP's contain conditions to minimize the impact ofthe use on adjacent properties. To achieve this, the Zoning Ordinance sets out the general provisions and criteria applicable to all uses authorized by a CUP. The ordinance also describes the procedures governing the application and review process. When considering whether to approve or deny a CUP, the City Council has the discretion to impose site specific conditions designed to mitigate the potential impacts on adjacent properties. Staff believes that the concerns raised by the petitioner and mitigating measures to potential environmental impacts in the CUP are included in the approving resolution. Staffs review of the project included issues listed in the DNR Mining Handbook, the same items that would be reviewed in an EA W. Staff also contacted a private consultant with experience preparing an EA W for a mining operation, the Department of Health, the DNR, and the MPCA to question potential environmental impacts. The project was further referred to Scott County, the City of Shako pee, the PLSL Watershed District, and SMDC. To this end, a review of potential issues has been conducted and mitigative measures to reduce/eliminate the impacts have been incorporated into the CUP approving resolution. As stated in the Zoning Ordinance (1108.202), the Planning Commission and staff have concluded the proposed excavation of sand and gravel is (1.) Consistent with the goals and policies on the Comprehensive Plan; (2.) Not detrimental to the health, safety, morals, and general welfare ofthe community as a whole; (3.) Consistent with the intent and purpose of the Zoning Ordinance; (4.) Will not cause undue adverse impacts on governmental facilities, service, or improvement, existing or proposed; (5.) Will not have adverse impacts on the use and enjoyment of properties in close proximity. The review and approval is site specific and sensitive to the petitioners concerns. 1:\99fi1es\99cup\99-075\99-075cl.doc Page 10 The Planning Commission and staff recommend approval of the CUP request subject to the following conditions: A.

The requirements for environmental review, including the preparation of an EA W, can be found in the Minnesota Rules, chapter 4410. The procedures to be followed in making the EA W decision are set forth in part 4410.1100. Key points in the procedures include: 1. No final government approvals may be given to the project named in the petition, nor may construction on the project be started until the need for an EA W has been determined. Project construction includes any activities which directly affect the environment, including preparation of land. If the decision is to prepare an EA W, approval must be withheld until either a Negative Declaration is issued or an Environmental Impact Statement (EIS) is completed (see part 4410.3100, subpart 1, page 35.) 2. A first step in making the decision regarding the need for an EA W would be to compare the project to the mandatory EA W, EIS and Exemption categories listed in parts 4410.4300,4410.4400, and 4410.4600, respectively. If the project should fall under any of these categories, environmental review is automatically required or prohibited. If this should be the case, proceed accordingly. 3. If preparation of an EA W is neither mandatory nor exempted, the City has the option to prepare an EA W. The standard to be used to decide if an EA W should be done is given in part 4410.1100, subp. 6. Note that this requires that a record of decision including specific findings of fact be maintained.

You are allowed up to 30 working days (Saturdays, Sundays and holidays do not count) for your decision if it will be made by a council, board, or other body which meets only periodically, or 15 working days if it will be made by a single individual. You may request an extra 15 days from EQB if the decision will be made by an individual. 5. You must notify, in writing, the proposer, the petitioners' representative and the EQB of your decision within five working days. I would appreciate your sending a copy of your record of decision on the petition along with notification of your decision for our records. This is not required, however. 6. If for any reason you are unable to act on the petition at this time (e.g., no application has yet been filed or the application has been withdrawn), the petition will remain ig effect for a period of one year, and must be acted upon prior to any final decision-concerning the project identified in the petition. Notice of the petition and its assignment to your unit of government will be published in the EQB Monitor on January 24,2000.

Rule pt. 4410.1100, subpt. 2, in connection with the proposed sand and gravel mining operation of Ryan Contracting Company ("Ryan Contracting") in the City of Prior Lake, and (2) petitioners' request that the City require an EA Wand deny the pending application for a conditional use permit ("CUP"). This petition should be granted because of the significant potential adverse environmental effects associated with the proposed project, and because Ryan Contracting may to be impermissibly attempting to avoid environmental review by improperly segmenting its proposed project in order to fall below the 40-acre threshold for a mandatory EAW. The potential significant adverse effects from the project include, among others: (i) impermissible impacts to Boiling Springs and the Savage Fen, 11 Exhibit A identifying the petitioners and this memorandum and its attachments in support of the petitioners' requests are attached to and incorporated into the Petition forEAW. " r 1'-.'.'.---"----.'.--'...-. DORSEY & WHITNEY LLP January 14,2000 Page 2 (ii) interference with, and possible contamination of, the drinking water resources of the Shakopee Mdewakanton Sioux Community (the "Community"), (iii) creation of unacceptable safety hazards and congestion on Scott County Road 42 and McKenna Road, and -~:.... (iv) other environmental impacts on surrounding communities. Under the Minnesota Environmental Policy Act ("MEPA"), Minn. Stat. ch. 116D, and the applicable rules of the Minnesota Environmental Quality Board ("MEQB"), when, as here, there is material evidence indicating that a proposed project "may" create the "potential for significant environmental effects," the EAW petition must be granted. Minn. Rules pt. 4410.1100, subpts. 2, 6. This material evidence requiring completion of an EA W is outlined in more detail below. Not only is there sufficient material evidence to require granting of the petition, it appears that an EA W in fact is mandatory in this case even if this petition were not before the City Council. Under the MEQB rules, an EA W is mandatory for all gravel mining operations that will excavate 40 or more acres of land. Minn. Rule pt. 4410.4300, subpt. 12(B). Although Ryan Contracting claims that its mining operation will encompass only approximately 13 acres, the parcel in question in fact covers 50 acres and Ryan Contracting has provided no evidence establishing that the area available to mine is limited to 13 acres or that Ryan Contracting intends to restrict its operations to this single 13-acre phase. If it is reasonably likely that Ryan Contracting may expand its operations at any time in the foreseeable future beyond the 13-acre first phase in order to conduct excavation on, in total, 40 acres or more of the 50-acre site, then the entire site is subject to EAW review. Absent some binding commitment by Ryan Contracting not to expand its operations, it would appear likely-given the size and conditions of the site, and the nature of Ryan's operations-that the 40-acre threshold for a mandatory EA W will be exceeded. The Project Ryan Contracting's application for a CUP for the operation of a mine to be located on property owned by Richard McKenna and Joseph and Carolyn Kinney is presently pending -2- DORSEY & WHITNEY LLP January 14,2000 Page 3 before the City of Prior Lake.Y As described in the revised CUP application, the purpose of Ryan Contracting's project is to operate a sand and gravel strip mining operation within a 12.91 acre pit within a larger 50-acre parcel located within the City of Prior Lake. The proposed project site is located approximately 0.6 miles north of the uncontrolled intersection of Scott County Road 42, an (A) minor arterial route, and McKenna Road, the principal ac~ess road to the Community's north residential housing development which lies less than a mile from the proposed project site. The project, as proposed, would include removing, processing, stockpiling, and selling of the gravel and sand removed from the 50-acre site. The proposed CUP developed by staff from the City of Prior Lake would allow Ryan Contracting to extract annually from the site up to 1,000,000 gallons of groundwater without further review or oversight by any governmental authority. Ryan Contracting anticipates that the mine would operate for a minimum of ten years. According to the CUP application, topsoil would be stripped from an excavation area encompassing approximately 12.91 acres and approximately 500,000 cubic yards of material would be mined. The application for the CUP was submitted to the City of Prior Lake Planning Commission (the "Planning Commission"), and it is set for review by the City Council later this month. Prior Lake staff apparently has recommended issuance of the CUP without preparation and review of an EA W. Brief Description of the Potential Environmental Effects The potential negative environmental effects of the proposed gravel mining operation are extensive. However, there has been absolutely no investigation, inquiry, or study conducted to determine the likelihood or extent of these effects. Hundreds of individuals will be directly affected by the immediate consequences of such a mining operation located in a residential area, and thousands could be indirectly affected by the wide-reaching impact of factors such as significantly increased traffic congestion, heightened safety concerns, excessive noise, air, and water pollution, and deleterious impacts on infrastructure in the surrounding areas. Moreover, both drinking water sources and sensitive and unique environmental resources may be harmed by the proposed mine. Y The legal description of the proposed location of the operation is the SE 1/4, Section 22, Township 115, Range 22. -3- I I T. ._.._._--. DORSEY & WHITNEY LLP January 14,2000 Page 4 Under MEP A, these potential significant impacts must be evaluated before the proposed project may be allowed to proceed further. Minnesota courts have made it clear that MEP A requires timely and adequate review of potential impacts before they occur and before permits are issued. It is not enough for a governmental body to rely on ongoing monitoring and administrative oversight as a substitute for an EA W or EIS, as applicable, when considering the potential im'p,act of a proposed project on the environment. See Trout Unlimited, Inc. v. Minnesota Dept. of Agriculture, 528 N.W. 2d 903,909 (Minn. Ct. App. 1995) (Commissioner of Agriculture, in deciding that environmental impact statement was not required for a proposed irrigation project, improperly relied on future permitting or monitoring efforts to control or redress potential problems. The purpose of the environmental review process "is to determine the potential for significant environmental effects before they occur [; by] deferring the issue to later permitting and monitoring decisions, the Commissioner abandoned his duty to require an EIS where there exists a 'potential for significant environmental effects.'" (original emphasis)). Further, it is the governmental body's duty to require sufficient information to evaluate all potential significant impacts; the responsible governmental unit may not ignore material issues that have been raised and then contend that there is insufficient evidence of actual harm to decline to conduct the environmental review required by the MEP A. Id. The burden lies with the project proposer, and ultimately with the responsible governmental unit, to provide sufficient information so that meaningful analysis of potential impacts can be completed before any permit is issued. Only when this process is completed may the governmental body determine that no further environmental review is necessary, that all required mitigation measures have been put in place, and that a permit for a project may be issued. In this matter, the issues outlined below have not been studied as required, and therefore an EA W must be completed. Under Minn. Rule pt. 4410.1100, subpt.6, the City may not proceed with considering the CUP application until the issues raised below have been evaluated and the EA W petition has been acted upon in accordance with all of the applicable rules of the MEQB. See MEQB, "Guide to Minnesota Environmental Review Rules," at 7-8 (1998). (responsible governmental unit may not issue final decision to grant approval of proposed project while an EA W petition is pending). 1. Traffic The proposed mining operation likely will have a severe negative effect on traffic patterns and road infrastructure, as well as the safety and well-being of residents who reside in the -4- DORSEY & WHITNEY LLP January 14, 2000 Page 5 immediate vicinity of the project site. The principal adverse impacts related to traffic are outlined below. Congestion and Disruption Without doubt, the proposed mining operation will increase traffic levels and cause congestion and disruption on both McKenna Road and County Road 42. This is a particular concern given the lack of any signalization at the intersection of these two roads and the planned improvements along County Road 42 which are scheduled to commence in 2001. Ryan Contracting has provided no meaningful data to assist Prior Lake or other interested communities and citizens in assessing the implications of these inevitable traffic impacts. Given the complete absence of traffic information from Ryan Contracting, the Community has.undertaken a preliminary traffic review that is outlined in the enclosed report prepared by the Community's Land and Natural Resources Department. The report analyzes anticipated traffic impacts under two likely roadway-utilization scenarios in connection with the proposed mining operation. Both scenarios show that the truck trips associated with the mining operation not only would have significant adverse effects on McKenna Road ~, traffic volume increases ranging from approximately 17 to 50 percent), but also would cause material increases in traffic ~, up to nearly 10 percent increase in passenger-car equivalents) and other disruptions on County Road 42, especially taking into account the effect of large, heavily loaded gravel trucks starting from standing stops and entering high-speed traffic at the uncontrolled McKenna/42 intersection. Given the existing high volumes of traffic on County Road 42, and its importance to business and residential users in Scott County, as well as the importance of McKenna Road to local residents, these potential impacts at a minimum deserve careful evaluation. Neither Scott County, Prior Lake nor anyone else has studied these traffic impacts in a systematic, scientific manner based on a thorough review of appropriate data. Alternative possible scenarios besides those outlined in the Community's enclosed report may show even more disruption from the proposed project. It would be highly imprudent to authorize the project to proceed without requiring further review of these very basic traffic-impact considerations. Safety -5- I I DORSEY & WHITNEY LLP January 14,2000 Page 6 Not only has Ryan Contracting failed to provide basic information on traffic volume and congestion concerns, it has completely ignored issues related to highway safety. In the first instance, McKenna Road, which would provide access to the gravel trucks entering and exiting the project site, is the main access road for residents of the nearby Community's northern housing development. Over 45 Community residents currently live in this development, and more homes..are under construction. In addition, there are other, non-Community members resident in tHe immediate vicinity of the proposed mine that have objected to the project. Further, McKenna Road is the only route for local residents seeking access to County Roads 42 and 83. The combination of heavy local residential traffic and large, loaded gravel trucks on a narrow, two-lane local road presents grave concerns from a safety standpoint. In particular, as discussed in the enclosed report, sight lines along McKenna Road are severely restricted due to the two sharp "S" curves and hills located in the immediate vicinity of the proposed project. These sight restrictions are a particular major concern from a safety standpoint because McKenna Road is the route that school buses use to transport children to and from the residential areas immediately to the west of the proposed mine. Furthermore, the movement of slow-moving, fully-loaded gravel trucks onto and off of County Road 42 presents another safety issue. Traffic volume on County 42 is generally very significant, and vehicles frequently travel at high speeds (the posted limit is 55-miles per hour) in the vicinity of the McKenna Road intersection. This intersection is not signalized. The dangers presented by this situation are obvious. Despite these circumstances, there apparently has been no analysis of traffic-related safety issues in connection with the Ryan Contracting project. This oversight should not be allowed to continue. The necessary review should be completed, and appropriate safety and mitigation measures should be adopted, before incidents occur, not after. Infrastructure Impacts Similarly, no information has been provided by Ryan Contracting with respect to the likely impacts of its operations on the structural capacities of McKenna Road and County 42. Ryan Contracting should be required to provide information adequate to analyze infrastructure impacts and to the development of necessary mitigation and maintenance measures. -6- DORSEY & WHITNEY LLP January 14,2000 Page 7 It has been conceded that gravel trucks traveling regularly along McKenna Road would accelerate the deterioration of its surface, and create the need for continuous repairs and resurfacing. Ryan Contracting in the CUP application claims that it will be responsible for maintaining the condition of McKenna Road in "as good as it is now or better" while the gravel pit is in operation. There is, however, no apparent analysis or data with respect to the actual extent and timing of the anticipated damage that the mining operation will create; the implications:'of such damage for users not associated with the project in terms of delay, safety and other relevant considerations; 'J! the type, frequency and reliability of repairs that will be necessitated; or Ryan Contracting's ability to carry out or fund such repairs. In addition, McKenna Road continues from the City of Prior Lake into the City of Shakopee to the north of the proposed mining site. There is nothing in the record to show that Ryan Contracting has made any comparable arrangements with Shakopee to protect that northern segment of McKenna Road and to repair any damage caused by the truck volume. It appears that the City of Shakopee may not even have been notified ofthis project and its effect on that city's roads. Moreover, Ryan Contracting has made no comparable commitment to repair damages caused to County Road 42. Scott County, which will be responsible for all repairs and resurfacing caused by gravel trucks, also apparently has received either no, or at best limited, information regarding these infrastructure impacts. Indeed, it is possible that the County has not seen the revised CUP application given that its review of the project apparently preceded this latest version of the project proposal. County 42 Improvements County Road 42 is scheduled to be upgraded beginning later this year from the signaled intersection at County Road 21 (east of McKenna Road) west to the intersection with County Road 83. This section of the roadway, of course, includes the intersection at McKenna Road. The increase in heavy truck traffic associated with the proposed mining project may interfere with the County 42 upgrade as described in the enclosed report. In particular, when certain portions of County 42 are closed during the construction of improvements, McKenna Road likely will provide an alternative route to some destinations. This will substantially increase traffic on "J! Continuous repairs to McKenna Road no doubt will further complicate and impede traffic to and from surrounding communities, as lanes of traffic are closed and additional equipment brought in to make necessary repairs. -7- rn . .-..---r-.-.--.....--..-.--r...----..--..--........--......--.- DORSEY & WHITNEY LLP January 14, 2000 Page 8 McKenna, and the existence of this increased traffic, combined with the heavy trucks from the mining operation, will exacerbate all of the traffic and safety concerns outlined above. Once again, however, there is nothing in the CUP application, staff report or draft CUP addressing these concerns. 2. W a~sr Resources -.' The proposed mining project also has serious potential negative effects on water-related resources near the project site. As with traffic, there is essentially no reliable information, study or analysis provided by Ryan Contracting addressing these important environmental issues. An EA W is needed to provide the data needed for Prior Lake to develop appropriate protections to prevent these negative effects. Drinking-Water Protection The Community has a public water supply well located in the immediate vicinity of the proposed mining operation. See site map attached hereto. The entire north water service area of the Community depends on the quality of this water for its drinking-water supply. As explained in the enclosed report, the proposed mining project falls directly within the drinking-water protection area of the well upon which the Community depends, and there has been absolutely no inquiry into the possible effects on drinking water of the mine, either in terms of possible interference with the Community's well or potential contamination of the aquifer supplying the Community's well. The Community's initial comments on the proposed project, dated October 7, 1999, explain the concerns about surface activities on the mine site which could result in migration of contaminants to the groundwater resources on which the Community relies. As discussed below, these concerns have not been addressed adequately either by Ryan Contracting or by the draft CUP. Moreover, Ryan Contracting's CUP application explains that the proposed project will use substantial quantities of water for dust control, processing and other purposes. Although the CUP application suggests that Ryan Contracting intends to use water from sedimentation ponds rather than a water-supply well, no commitment is made not to install such a well. ~ ~ Further, the CUP application does not address possible de-watering associated with the proposed operation. There simply is not enough information in the CUP -8- DORSEY & WHITNEY LLP January 14,2000 Page 9 Rather, the draft CUP prepared by City staff would allow a well with a use capacity of up to 10,000 gallons per day or 1 million gallons per year without any further governmental oversight of any kind. (The only proposed CUP restriction is that for any groundwater use over those thresholds, a DNR permit would have to be obtained.) Groundwater usage at the levels contemplated by the draft CUP has at very serious adverse environmental implications for the Community's residential water supply that should be addressed by an EA W. -.:.,.. More specifically, the public well upon which the Community depends for its domestic water supply draws its water from the Jordan aquifer. The well is cased through the overlying glacial material and grouted into the Prairie du Chien formation. It is open for the entire thickness of the Jordan formation. The groundwater flow within these formations is from southeast to northwest, or, in other words, from the proposed project site towards the Community's supply well. If a well is installed by Ryan Contracting on or near the site of the proposed mine, it will pose a distinct threat to the Community's water supply. First, usage at this level could interfere with the ability of the Community's domestic supply well to draw adequate water. As explained in the enclosed report, the Community has legally-protected rights and priority preferences to this water under federal law . Ryan Contracting may not interfere with the Community's rights, and Prior Lake may not authorize such potential interference without evaluating this possibility. No study of this potential interference has been provided. Second, as discussed in the enclosed report and the Community's earlier comments to Prior Lake, the proposed gravel mining operation presents a variety of risks of releases of pollutants and contaminants associated with the operation to the environment. 21 Not only do application to decipher whether or not de-watering is a potential concern. 21 For example, although Ryan Contracting states that there will be no fuel storage on the project site, the CUP as drafted does not contain any such restriction. Equipment and machinery containing large quantities of fuel will be parked and stored on location. Any leakage from this machinery could have devastating effects on the groundwater. Potential oil and gasoline leaks could negatively impact the underlying aquifer; even if not directly introduced into the groundwater on-site, runoff from the site and seepage could infiltrate south of the project, and seep into the aquifer. Additionally, "dust control" may include capturing particulates in the air by spraying water and perhaps a -9- II --r DORSEY & WHITNEY LLP January 14,2000 Page 10 these risks c~me from the equipment, trucks and fuels utilized on the site, the proposed sedimentation ponds themselves are possible sources of such releases. The construction of any wells for the potential mining uses outlined in the CUP application or the commencement of any dewatering activities would present additional risks. Because there are no effective barriers to migration of contaminants from the site to the Jordan aquifer in which the Community's water supply well.is located, should there be any contamination from the proposed project site, the quality of tne Community's drinking water supply will be imperiled. It is imperative that all potential sources of pollution associated with proposed project be analyzed in depth so that adequate mitigation and control measures may be developed and incorporated into any CUP issued by Prior Lake. Boiling Springs and the Savage Fen The water usage contemplated by the draft CUP also may impermissibly iIIlpact either the Boiling Springs, the unique water feature in Eagle Creek in Shakopee, and the Savage Fen, the calcareous fen complex located in Scott County. As has been well documented by extensive study in recent years led by the Minnesota Department of Natural Resources (DNR), the Savage Fen and Boiling Springs are extremely important natural resources created by groundwater from the Jordan and Prairie du Chien formations, and these resources are very sensitive to disturbance from development activities. Because of the fragile nature of these resources, DNR has utilized its statutory authority to establish a policy providing that no-net decrease of water levels at Boiling Springs or the Savage Fen may be caused by proposed developments. ~ DNR enforces this policy through use of a multiple layer analytical element model (generally known as "MLAEM" or "Strock's model") to evaluate the potential impact of proposed development on water levels at Boiling Springs and the Fen. liquid dust control agent on roads and in the air surrounding the site. There has been no study conducted to determine whether or not such activities related to the mining operation may have a negative effect on groundwater, either through direct contamination of the aquifer, or through indirect contamination due to runoff from the site onto the property of the Community. ~I Calcareous fens are protected by Minn. Stat. ~ 1030.223, which provides: "Calcareous fens, as identified by the [DNR] commissioner, may not be filled, drained, or otherwise degraded, wholly or partially, by any activity, unless the commissioner, under an approved management plan, decides some alteration is necessary." -10- DORSEY & WHITNEY LLP January 14, 2000 Page 11 The petitioners have been advised that DNR staff responsible for oversight of Boiling Springs and the Fen have not been made aware of the proposed Ryan Contracting project. DNR staff have expressed concern that a project at this location, if it were to utilize significant amounts of groundwater, could cause impermissible water reductions at the Savage Fen, and, even more likely because of its closer proximity to the proposed mine, Boiling Springs. The water-use l~yels allowed by the draft CUP without further governmental review (up to 10,000 gallons per (fay and 1 million gallons per year) would almost certainly constitute such a significant use as to violate DNR's no-net decrease standard under the Strock's model. Unfortunately, neither the CUP application nor the City staff report provides the meaningful data and analysis necessary to evaluate what actual impacts are likely to occur.lI Although Ryan Contracting claims that it does not intend to drill any well on site, there is nothing in the draft CUP language to prevent it from doing so. To the contrary, the draft CUP allows the very substantial water use described above that could adversely affect the Fen and Boiling Springs. Likewise, there is no reliable information in the CUP application addressing possible dewatering or other water-consumption activities common in gravel mining operations. These issues must be addressed before the City takes final action on the CUP application, so that impermissible impacts to these invaluable environmental resources do not occur. Wetlands In addition to the Savage Fen, the CUP application makes reference to DNR wetland #70- 247W located on the proposed project site. The boundaries of this wetland are not identified in the materials submitted by Ryan Contracting. Under Minn. Stat. ch. 103G, no filling, draining or other action impacting this protected wetland may occur without prior governmental approval. Because the precise boundaries of this wetland have not been delineated by Ryan Contracting, there can be no assurances that the mining operation will not unlawfully damage this resource. 11 Minnesota courts also have recognized the Savage Fen as a unique wetland requiring protection under the authority of federal law. See City of Savage v. Formanek, 459 N.W.2d 173, 174 (Minn. Ct. App. 1990). The record is unclear as to whether or not the U.S. Army Corps of Engineers and U.S. Fish & Wildlife Service have been apprised of the proposed mining operation. -11- I I --,-_._-- DORSEY & WHITNEY LLP January 14,2000 Page 12 Ryan Contracting's proposal to engage in annual testing is insufficient under existing law because the full scope of the wetland must be located definitively before a permit is issued. The usefulness of the future water quality testing proposed in the CUP is dependent upon having baseline data on the wetland. This baseline data does not exist, and neither the CUP application nor the draft permit address the need to gather data prior to mining. Once again, this absence of relevant information must be remedied before the pending application moves forward, and the EA W proce~s provides the requisite legal forum for the required review. 3. Impacts on Neighboring Communities In addition to the above environmental issues on which there is no meaningful information in the record, this project, if allowed to proceed, will have other significant negative effects on neighboring residential communities. An EA W should be ordered to determine the extent of these effects, and potentially identify options to eliminate or at least substantially mitigate them. Dust There has been no assessment of the amount of dust a project such as this will generate. Obviously, a substantial amount of airborne pollutants will be generated as evidenced by the volume of water consumption that the City's draft CUP contemplates allowing Ryan Contracting. The exact amount of water and the effectiveness of various dust-control options have not been evaluated. Likewise, there has been no determination of the scope of the areas that will suffer from this pollution. All phases of this operation will generate dust and other airborne particulates, including the stripping of the land, mining of the materials, screening, and hauling. There appears, nonetheless, to be no plan in place adequate to contain the dust and particulate matter generated. The application for the CUP submitted by Ryan Contracting only covers watering roads used to haul the material mined from the land. This is insufficient. In the absence of more information, there simply is no way for Prior Lake to determine whether or not the measures contemplated by the CUP application are sufficient to control airborne pollution. Lh!hting The mining project anticipates operating from 6 A.M. to 8 P.M. Monday through Friday, and 8 A.M. to 5 P.M. on Saturdays on a seasonal basis. Depending on the time of year, artificial lighting will be required to properly illuminate the site itself, surrounding areas, and hauling -12- DORSEY & WHITNEY LLP January 14,2000 Page 13 roads to and from the project given these operating hours. Located only several hundred feet from many homes, any such lighting will have a significant negative impact on the residents. Once again, however, neither the CUP application nor the City staff report evaluate the extent of lighting that will be used, the potential disturbance that may result, and any effective measures to control this problem. NoISe Excessive noise also will adversely affect the area near the proposed operation. Noise will be generated by mining equipment, screening processes, and hauling. Under the current plan, the site will be operating up to 14 hours each day, six days per week. Further inquiry should be made into the extent of the noise, and the steps that can be implemented to reduce the noise as much as possible. Without such restrictions, the project noise will adversely affect the value of adjacent properties and restrict the use and enjoyment of the properties by their owners, all without the benefit of any meaningful study to determine whether effective and reasonable mitigation measures are available. Aesthetic Impacts and Restoration The mining operation not only creates potentially significant adverse environmental effects, it will be unsightly, both now and in the future, and will impair future development compatible with surrounding properties. Under Ryan Contracting's current plan, the regular flow of heavy machinery and truck traffic apparently will not be shielded by any effective berm or vegetative barrier. Similarly, the absence of a detailed and comprehensive restoration plan for the period after the mine closes virtually guarantees that the site will continue to present problems in the future, particularly in the light of the significant potential environmental impacts outlined above. The CUP application suggests that future restoration will be consistent with a return of the land to agricultural uses. Given the rapidly expanding urban development along and near County Road 42, this claim lacks any credibility. The apparent willingness of staff to accept this claim at face value demonstrates the failure to take the required hard look at how this property will be used in the future, and at what must be done while the mine is operating and at the time it is closed to ensure that it is restored to a safe and usable condition that is not adversely impacting other properties. 4. Summary -13- I I -.-.----r-- ..-----y--.---.-.--------------------------. DORSEY & WHITNEY LLP January 14,2000 Page 14 The discussion above clearly establishes that there is substantial and material evidence of potential significant environmental impacts associated with this proposed project that have not been evaluated. Under the EQB rules, the existence of this evidence requires that the petition for an EA W be granted. Minn. Rules pt. 4410.1100, subpts. 2, 6 (EA W required upon showing that the project "may have the potential for significant environmental effects") (emphasis added). It is not sufficient to suggest that these matters can be explored later or addressed in some future new permit or other form of governmental oversight when the potential impacts become clearer when the mine begins operation. Minnesota courts have recognized that such a course of action is untimely and violates the letter and spirit of the Minnesota Environmental Policy Act.~ An EA W will allow Prior Lake to conduct the type of thorough review that the MEP A requires before a permit can be issued, and will allow the City to effectuate its responsibilities to those persons who would be adversely affected by the proposed project if it were not properly reviewed and regulated. The Proposed Project May Require A Mandatory EA W As A Phased Action Under the MEQB rules, an EA W is mandatory for all gravel mining operations that will excavate 40 or more acres of land. Minn. Rules pt. 4410.4300, subpt. 12(B). These rules also require that, in determining whether an EA W is necessary, all phases of a development must be considered. Id. at pt. 4410.1000, subpt. 4. Phased actions are defined as: "two or more projects by the same proposer that a [responsible governmental unit] determines will have [A] environmental effects on the same geographic area; and [B] are substantially certain to be undertaken sequentially over a limited period of time." Id. at pt. 4410.0200, subpt. 60. In this instance, Ryan Contracting claims that its mining operation will encompass only approximately 13 acres, but the parcel in question in fact covers 50 acres, and Ryan Contracting has provided no evidence establishing that the area which can be mined is in fact limited to 13 acres or that Ryan Contracting intends to restrict its operation to a single 13-acre phase. In fact, ~ See Trout Unlimited, Inc. v. Minnesota Dept. of Agriculture, 528 NW 2d 903 (Minn. Ct. App. 1995) (Commissioner of Agriculture, in deciding that environmental impact statement was not required for a proposed irrigation project, improperly relied on future permitting or monitoring efforts to control or redress potential problems; the purpose of environmental review under MEP A is to determine the potential for significant environmental effects before they occur). -14- DORSEY & WHITNEY LLP January 14,2000 Page 15 given the lO-year operating period that Ryan Contracting projects for the mine, the apparent availability of usable material that could be removed from most or all of the 50-acre site, the demand for sand and gravel, and Ryan's past operating history, it is reasonably likely that the proposed 13-acre site is only the beginning of a larger operation. Unless Ryan Contracting is able to provide persuasive and binding evidence that it will not expand Irs operations to exceed the 40-acre threshold, a mandatory EA W for the entire site should be ordered to ensure that all potential impacts of the possible phases throughout the 50- acre site are examined. Absent such evidence, there is a likelihood that in the foreseeable future there will be attempts to expand the scope of the mining operation, and it is reasonable to believe the 40-acre threshold for a mandatory EA W will be exceeded. This provides further reason that the City should require an EA W in connection with this operation to ensure a timely review of all potentially affected property associated with the proposed project. Conclusion For the reasons set forth above, the petitioners respectfully request that the City of Prior Lake grant their petition and require preparation of an EA W in accordance with Minn. Rule pt. 4410.1100. Petitioners further request that the City of Prior Lake deny the pending CUP application. k~~ - Q: 'A. Fontaine -15- I I ., j,~' 0,\ -.. . ~ PETITION FOR EA W The undersigned hereby petition the City of Prior Lake, pursuant to Minnesota Rule, part 4410.1100, to request that the City order the completion of an environmental assessment worksheet ("EA W") for Ryan Contracting Co.'s proposed sand and gravel mining operation ("Project") located within' the southeast quarter section of Section 22, T 115, R 22, located on McKenna Road. We request that the EA W be performed before the City acts upon Ryan Contracting's conditional use permit ("CUP") application because the Project poses the potential for significant adverse environmental effects, including, but not limited to, (i) impermissible impacts to Boiling Springs and the Savage Fen, (ii) interference with, and possible contamination of, the drinking water resources of the Shakopee ~dewakanton Sioux Community (the" Community"), (iii) the creation of unacceptable safety hazards and congestion on Scott County Road 42 and McKenna Road, and (iv) other impacts as more fully set forth in the attached memorandum. Petitioners further request that Ryan Contracting's CUP application, as currently pending before the City of Prior Lake, be rejected.

SUBJECT. A review of some of the impacts that may result from the gravel mine proposed by Ryan Contracting near the North Residential and Brewer Subdivisions. 2. ATTACHMENTS. Map showing well location and proposed pit location. 3. EXPLANATION. The following information is a summary of some ofthe potential impacts and other issues related to the proposed mining operation. Where assumptions were made they are listed before the analysis. TRANSPORTATION ANALYSIS General Assumptions on Gravel Hauline. . Total production reserve of 500,000 cubic yards . A mine life often years . Use of the pit on a project basis . Two major projects a year requiring 25,000 cubic yards of material . A project period of five days for each project . A truck size of20 cubic yards . A 14 hours working day (maximum from the CUP) . Hauling five days a week General Assumptions on Traffic. . Total traffic volume is equal to or greater than in 1996 . Daily trip counts will increase over the next ten years . Roadway quality will remain constant or improve Hauline Scenarios. SCENARIO 1, five day project life. . A total of 5,000 yards per day mined, screened and hauled. . A total of250 round trips a day (250 loaded trucks out, 250 empty trucks in for a total of 500 trucks per day) 1 . Eighteen loaded trucks per hour . A loaded truck every three minutes for 14 hours a day. . A total of 36 trucks, loaded and unloaded per hour · A truck, either loaded or unloaded, every one and one half minutes for 14 hours each day. SCENARIO 2, fifteen day project life. . A total of 1667 yards per day mined, screened and hauled. . A total of 83 round trips a day (83 loaded trucks out, 83 empty trucks in for a total of 166 trucks per day) . Six loaded trucks per hour . A loaded truck every ten minutes for 14 hours a day. . A total of 36 trucks, loaded and unloaded per hour . -:A truck, either loaded or unloaded, every five minutes for 14 hours each day. Roadway Data. McKenna Road. A narrow, two lane five ton road with two 90 degree curves and a hill in the vicinity of the truck entrance point. To the north the road is a 9 ton road two lane road that was recently re-constructed. Sight lines are restricted due to the two curves and hills located in the immediate areas ofthe planned entrance onto this roadway. County 42. County 42 is a four lane rural section east of McKenna Road that was recently reconstructed.. To the west it is a two lane rural section with degraded pavement. The section of County 42 west of McKenna Road to County 83 is scheduled to be re-constructed and upgraded to four lanes over the next two years. This scheduled upgrade will require closing portions of County 42 during construction. This will have a material impact on traffic patterns and may require gravel trucks to travel north on McKenna Road. This will bring the heavy truck traffic directly past residential areas on a narrow city street. Intersection. The intersection of County 42 and McKenna Road is controlled by a stop sign on McKenna Road southbound. There is no semaphore or other automated signal device at the intersection. Historical Traffic Use Data. Traffic counts for this area are included in the City of Shakopee Transportation Plan, April, 1998 completed by WSB & Associates, Inc. The traffic data is from 1995-96. The data is reported in existing daily traffic trips. . McKenna Road. A total of 500 daily trips on McKenna Road. . CO 42 West of McKenna. A total of 10,500 daily trips. . CO 42 east of McKenna and CO 21. A total ofl3,500 trips. Traffic Analysis. Two general aspects of traffic are analyzed: 1) impacts from additional traffic; and 2) impacts for traffic type. Each of these general aspects will create safety, infrastructure and nuisance impacts. 2 I I .1----------"--.-------- Additional Traffic. · McKenna Road. Under Scenario I, above, the impact will be a 50% increase in traffic during the five operational days of the project. This is a very significant increase and will certainly create congestion and delay. At that point the road will be well beyond its designed capacity. Under scenario 2, the increase is 16.67%. This is also a significant increase and it is likely to cause some congestion. The higher traffic flow could increase the number of safety related incidents during the congested period. This level of use by heavy truck traffic will have negative impacts on the condition of McKenna Road. The dust, congestion and delays in traffic flow will impact the persons currently using McKenna Road for access to their residence or as a commuting route. Restricted sight lines pose a significant potential for accidents during high truck traffic periods. See Traffic Type, below, for further analysis. · County 42. The increased in traffic volume under scenarios one and two, respectively, are 2.38% and .79%. While these increases are not likely to cause traffic congestion by them'selves, the traffic type exacerbates any issues. Impacts related to truck traffic can be converted to automobile equivalents. For rolling terrain such as that in the impacted area, a loaded truck equals approximately 4 automobiles. This increases the impact under Scenario. 1 to approximately 9.5% passenger car equivalents and Scenario 2 to 3.16% passenger car equivalents. Traffic Type. The type oftraffic introduced by the mining operation is distinctly different from the current traffic type. Present use is primarily by single automobiles or light trucks for local traffic and short distance commuting. The mining operation will introduce heavy truck traffic. When loaded, these trucks accelerate slowly, have long stopping distances and are much less maneuverable. When introduced into the existing traffic type they have an impact on safety and traffic flow far beyond the simple addition of numbers. The fact that there is a required turning movement at the McKenna Road/County 42 intersection exacerbates this problem. Large, heavily loaded gravel trucks will be required to make a left or right turn onto an arterial street with a speed limit of 55 Miles Per hour (MPH). This turning movement will occur at an intersection with no traffic controls on County 42. There is an non-quantified potential for increased traffic accidents related to this activity. There will be significant traffic delays related to the mining operation. Loaded gravel trucks will have to turn left onto County 42. These trucks accelerate slowly. They will create congestion at the intersection requiring other traffic to wait for extended periods of time. After they turn onto County 42, they will be introduced into fast flowing traffic on a major arterial roadway. This will force traffic on that roadway to adjust to the truck traffic. WATER ANALYSIS Backeround Data. The Shakopee Mdewakanton Sioux Community (SMSC) maintains its own Public Water Supply System (PWSS) to produce domestic use water for tribal members. This water supply system is regulated under the Safe Drinking Water Act by the United States environmental Protection Agency (US-EP A). The PWSS draws on local bedrock aquifers 3 for its primary supply. Groundwater within the external boundaries ofthe SMSC lands is tribal water and is under the jurisdiction ofthe federal government. The SMSC is in the process of establishing well head protection areas for its PWSS wells. This process is part of a joint program with the Minnesota Department ofHeaIth (MN- DOH), the US-EP A and the SMSC. Ten year time oftravel zones have been defined for SMSC wells by the MN-DOH. This is part ()f a sub-regional groundwater modeling effort being completed by the MN-DOH. This ten "year time of travel in shown on the enclosed map along with the well location and the approximate location of the proposed mining project. The proposed mining project falls within the ten year time of travel delineation. The proposed Conditional Use Pennit (CUP) allows use of up to 1,000,000 gallons of water per year for dust control. The CUP does not prohibit drilling a well on the project. The CUP does not prohibit washing operations on site. -.- -.' SMSC Well. The proposed project lies within the ten-year time of travel delineation for the SMSC PWSS well. The SMSC well is used as a domestic water supply. This situation causes two potential problems: 1) If a well is placed in this area and used to produce water for dust control and washing operations there is a potential for interference with the SMSC well; and 2) if any contaminates enter a well placed on the mining site they will be introduced directly into the aquifer supplying the PWSS well. The Jordan Aquifer in this area has a high transmissivity and the likelihood of interference between a well on the mine site and the Community PWSS well is very high. An aquifer test was performed on the McKenna Road PWSS well in 1997.1 The PWSS well was pumped at 50 gallons per minute. One observation well, OBS-A, was located across gradient approximately as far away as the mine would be located from the PWSS well. This observation well, OBS-A, showed drawdown within two minutes of beginning pumping the PWSS well? It is a fairly certain assumption that pumping a well located near the proposed mine would have some level of interference with the SMSC PWSS well. This higher the pumping rate, the greater the interference. The primary threat of contamination comes if a well is placed on the proposed pit site. There is a minor potential for impact from infiltration of surface spills or releases. Although the threat from infiltration of contaminates is not zero, there would be a significant delay from the time of any such spill or release to entrance into the bedrock aquifer. If a well is located on the mine site, there is a direct link from the surface to the bedrock aquifer and this threat becomes a very real consideration. Savaee Fen. If a well is installed on the mining site there is a potential for impacts on the Savage Fen, and other wetlands in the area, if the well is pumped to any significant degree. Tribal wetlands would probably not be affected by the pumping, but they may be impacted by any I See United States Geological Survey, Water-Resources Investigation Report 99-4183. USGS at 8. 4 II -.- ..'.--T ...---.----..-.----..... ..... .' .......-.-.-... .--...--..,.-- surface contamination. A well drawing on the Jordan Aquifer may impact the fen if sufficient water were to be withdrawn. The CUP analysis performed by the City of Prior Lake does not address this issue. The proposed mining operation is located on the edge of a buried valley. The regional water flows in this area has been modeled by both the Minnesota Pollution Control Agency (MPCA) and the MN-DOH. These models should be used to evaluate potential impacts of a well located at this site. .. Surface Water. Surface water flows from the proposed pit area directly onto SMSC tribal lands. There is a potential for surface contaminates to enter tribal lands. Tribal waters are under the environmental jurisdiction of the US-EP A. Surface flow of contaminates onto tribal lands or into tribal waters would create jurisdictional issues involving the State of Minnesota, the US-EPA.-and the SMSC. The CUP proposes water quality testing to address this issue. Although water quality testing is a valuable tool, it does not prevent contamination. The testing will only indicate contamination after the fact. The CUP does not require a spill or release contingency plan. Without such a plan and adequate safeguards, there is a potential for contamination of surface waters by fuel or other chemicals used in the gravel mining and processing operation. ADDITIONAL ISSUES End Use Plan. This area is not within the MUSA at the current time. If there is a planned residential end use it will require individual wastewater treatment (septic systems). In this case, the end use plan must be approved by the Scott County Environmental Office. The City of Prior Lake repealed its individual wastewater treatment ordinance several years ago. The control of those systems defaulted to Scott County. Scott County will most likely not allow septic systems to be installed in areas where the soil has been disturbed by mining. The Scott County Environmental Office has not allowed this in the past and is not likely to consider any change in policy. MPCA. . The MPCA requires an EA W for all gravel mining operations of 40 acres or more. This site contains approximately 50 acres. The CUP application calls for an approximate 12 acre mining area. The likelihood is that the entire area, or a significant portion thereof, will eventually be mined. This would become a phased project with the initial phase artificially restricted to fall under the required EA W limits. An EA W should be required assuming the entire are will be mined or Ryan should demonstrate that the remaining area does not contain gravel suitable for mining. . The MPCA requires permits for storm water runoff from mine and quarry stockpiles. The site is required to file a pollution prevention plan and follow best management practices. Any washing will also require a permit. 5 ; ] -Q u ~ :" '-- ,r LL ~ i ---\>< < x. /II -0 ;:0 a ~ <<;2<<0( "0 ::s 0 +z en G> -icn"ll&>cr-cn (1) ii1 ::Joj:::L cn~~ a. io~5;;!;l:o r- < ~i i~l ~ 0 (1) 0 s:: g.90!'< ~ Q) ~OJ :So - S' !It c5" ~ cncn g (1) ~~ OJ ::s CD &! en J I -1- ... 'G Minnesota Pollution Control Agency March 1999 Environmental Management at Aggregate Operations Aggregate production is an important Minnesota industry, producing sand and gravel and crushed stone for construction projects and other uses throughout the state. The Minnesota aggregate industry has recognized the economic and public relations benefits of progressive environmental management. This fact sheet summarizes pollution prevention opportunities and Minnesota Pollution Control Agency (MPCA) permitting requirements for aggregate operations. Some general information about permit programs administered by other agencies also is provided. If a new pit is started, or an existing one is expanded, by 40 acres or more, and the pit will have a mean depth of at least 10 feet during its existence, the project needs to have an Environmental Assessment Worksheet prepared. If the new pit or expansion will cover at least 160 acres, mined to a mean depth of 10 feet or more, an Environmental Impact Statement is needed. Contact the Environmental Quality Board at (651)296-8253 for more information on this process. For information on pollution prevention, permitting and/or compliance status, please contact the telephone numbers for the programs mentioned below. Fuel and Hazardous Materials Management When equipment is refueled, maintained or repaired outside the shops, special care must be taken to prevent spills, and to quickly contain and collect accidental spills. ?rh7eIripfoyee~are~chl1te'shourd]ie ]i:iiijedr.

Ruhl ABSTRACT (3) a confined, glacial-drift sand aquifer. Test results indi- cate that the Jordan Sandstone had a transmissivity of 6,267 tt2/d, a storativity of 1.193 x 10-4, a horizontal hydraulic conductivity of31 ftld based on a saturated thick- ness of204 ft, and a ratio of vertical to horizontal hydraulic. conductivity of 5.29 x 10-4. The pumped well was hy&auli- . cally connected to the Prairie du Chien Group observation well. No drawdown was observed in the observation well completed in the confined, glacial-drift sand aquifer; thus, a hydraulic connection ofthis observation well to the pumped well was not indicated. An aquifer test of the Prairie du Chien-Jordan aquifer was conducted in the Shakopee Mdewakanton Sioux Com- munity located southwest ofthe Twin Cities metropolitan area. A well open to the Jordan Sandstone was pumped at 600 gallons per minute for 57 hours. Drawdown was moni- tored in three obseFV~tion wells located near the pumped well. These wells were open to: (1) the Jordan Sandstone, the principal unit of the aquifer; (2) the Prairie du Chien Group, a secondary, carbonate-rock unit of the aquifer; and INTRODUCTION The Prairie du Chien-Jordan aquifer (fig. 1) is a major source of water for many communities of south- eastem Minnesota. The Jordan Sand- stone is the principal unit of the aquifer; the Prairie du Chien Group is a secondary, carbonate-rock unit of the aquifer. The Shakopee Mdewakanton Sioux Community (hereinafter, referred to as the Community) (fig. 2), located in the northern part of Scott County, Minnesota, has public-supply wells open to the Jordan Sandstone part of the aquifer. Hydraulic properties of the Jor- dan Sandstone were previously esti- mated from an aquifer test conducted in the southern part of the Community (fig. 2) (Strobel and Delin, 1996). Transmissivities of 4,710 to 7,660 tt2/ d and storativities of 8.24 x 10-5 to 1.60 X 10-4 were reported from this previous study. The purpose of this report is to present additional informa- tion from an aquifer test conducted in the northern part of the Community (figs. 2 and 3). The test was conducted to better define the hydraulic proper- ties of the Jordan Sandstone and to evaluate the hydraulic connection of the Jordan Sandstone to the Prairie du Chien Group and to a nearby confined, glacial-drift sand aquifer. Information from the test will be useful to tribal officials for development of Commu- nity water-management plans, to non- tribal government officials for devel- opment of regional water-manage- ment plans, and to water-resource investigators for subsequent studies on the hydraulic properties of the aqui- fer. The aquifer test was conducted by pumping water from a public works well open tothe Jordan Sandstone dur- ing a 57-hour period and measuring the drawdown in three observation wells. (After pumping was stopped, recovery in the observation wells could only be measured for about 4 hours, after which time operation of the pumped well had to be resumed because of the need to replenish com- munity water supplies. Thus, the recovery phase of the test was judged 1 to be of too short duration for reliable aquifer-test analyses.) The three observation wells were open to the following units: (l) the Jordan Sandstone; (2) the Prairie du Chien Group; and (3) a confined, gla- cial-drift sand aquifer in a bedrock valley located about one mile east of the public works well. Hydraulic prop- erties of the Jordan Sandstone were estimated from analyses of theoretical type curves developed by Neuman (1972, 1974, 1975) fitted to the draw- down data plotted for the observation well completed in the Jordan Sand- stone. Analyses of multiple aquifers and of multiple aquifer units were beyond the scope of the study; thus, the hydraulic properties of the Prairie du Chien Group and of the confined, gla- cial-drift sand aquifer were not esti- mated from test results. Test results were used to evaluate hydraulic con- nections of the pumped well to the Prairie Du Chien Group observation well and to the confined, glacial-drift sand aquifer observation well. a: :E OU) ~ ~~ ~ ~ffi a: ~U) w VI >- t) a: 6 <C N Z o ffi ~ td: () ::> o () > o o Cl N a: o 0 w -' Z <C <C - a.. a: co ~ <C () FORMATION OR GROUP UNDIFFER- ENTIATED GLACIAL DRIFT Z <C ~ () ~ Q.. :::I:;:, 00 w~ c:: <( c:: Q..

These valleys create discontinuities in the Prairie du Chien Group and Jordan Sandstone. The bedrock valley east of the test site extends downward into the St. Lawrence Fonnation (Balaban and McSwiggen, 1982). The Minnesota River flows through a bedrock valley to the north and west of the Commu- nity where bedrock units are exposed in some places. The bedrock valleys are filled with Late Wisconsin drift that consists of sparse and discontinuous lenses of sand and gravel embedded within till. These surficial sediments, which have a relatively low hydraulic conductiv- ity, overlie and cOIiUne the bedrock fonnations in some places. The water table typically is perched above the potentiometric surfaces of the under- lying bedrock aquifers because of the low hydraulic conductivity of the sur- ficial sediments. Ground water in the bedrock aquifers generally flows in a northwesterly direction through the study area and discharges into the Minnesota River. The Prairie du Chien Group and Jordan Sandstone, which are hydrauli- cally connected units, constitute a sin- gle aquifer. Hydraulic heads in the two units are similar (Delin, 1991). In some areas the potentiometric surface of the aquifer is below the top of the Prairie du Chien Grou;, thus, the aqui- fer is unconfined in these areas. Ground-water flow in the Jordan Sandstone is through intergranular pores (primary penneability). Ground- water flow in the Prairie du Chien Group is through dissolution channels and fractures (secondary penneabil- ity). The Jordan Sandstone is more important for ground-water supply than the Prairie du Chien Group because it typically has greater penne- ability than the Prairie du Chien Group. AOUlFER-TEST DESIGN A public works well completed in the Jordan Sandstone and located in the northern part of the Community was pumped at 600 gal/min for 57 hours. The pumping began on October 21, 1997 at I :00 PM, a time when day- time water use in the Community nor- mally declines. Thus, potential effects on early-time drawdown data from pumping privately owned domestic wells located near observation wells were minimized. The pumping rate was monitored with a 4-inch Badger Recordall II Tur- bometer that had an operating range of from 8 to 1,250 gal/min. The water- level drawdown in this well and in three observation wells were mea- sured during the pumping period. Dur- ing a 4-hour period prior to the start of pumping, static water levels were measured in the pumped well and in the three observation wells to define pre-test conditions. The three observation wells were: (1) the Brewer domestic well, herein- after referred to as OBS-A, which is completed in the Jordan Sandstone and located 100 feet north and 750 feet west of the pumped public works well; (2) a public works well (now aban- doned), hereinafter referred to as OBS-B, which is completed in the Prairie du Chien Group and located 1,200 feet south and 100 feet west of the pumped public works well; and (3) the YMCA Camp Kici Yapi well, hereinafter referred to as OBS-C, which is completed in a confined, gla- cial-drift sand aquifer and located 700 feet north and 4,300 feet east of the pumped public works well (fig. 3). OBS-A was cased to a depth of 257 feet and was open to 83 feet of the Jordan Sandstone (table 1). Although the portion of the Jordan Sandstone open to the well could not be precisely determined, the well probably is open to nearly the full thickness of the for- mation. The well definitely is not 5 open, however. to the full thickness of the Prairie du Chien-Jordan aquifer. which extends from III to 340 feet below land surface. The static water level in this well was 136 feet belov,' land surface. which was about 754 ft above sea level. OBS-B was cased to a depth of 151 feet and was open to 51 feet of the Prairie du Chien Group (table 1). Although the portion of the Prairie du Chien Group open to the well could. not be precisely detennined, the weli probably is open to about one-third to one-half the full thickness of the for- mation. The well is not open, however, to the full thickness of the Prairie du Chien-Jordan aquifer. If the thickness of the Jordan Sandstone is assumed to be 100 feet, the full thickness of the aquifer would extend from 150 to 302 feet below land surface. The static water level was 154 feet below land surface, which was about751 ft above sea level. OBS-C was cased to a depth of 140 feet and screened to a depth of 150 feet (table 1). The screened interval was open to a confined, ghicial-drift sand aquifer. The static water level was 61.8 feet below land surface, which was about 788.2 ft above sea level. The pumped well was cased to a depth of 264 feet and was open to 106 feet of the Jordan Sandstone below the casing (table 1). The diameter ofthe open-hole portion of the well is 14 inches. Although complete, open-hole penetration of the Jordan Sandstone could not be verified, the well proba- bly is open to nearly the full thickness of the fonnation. The well is not open, however, to the full thickness of the Prairie du Chien-Jordan aquifer, which extends from 110 to 370 feet below land surface. The static water level was 137 feet below land surface (static water-level altitude about 755 ft above sea level). Water levels in the pumped well and in OBS-C were measured manu- Table 1.

Water levels in OBS-A and in OBS-B were mea- sured by a pressure transducer con- . nected to a TROLL (SP4000) data logger manufactured by In-Situ Inc. Time increments between measure- ments, which initially were at a scale of seconds, were increased logarithmi- cally to one-hour intervals. The oper- ating range of the pressure transducers was from 0 to 30 pounds per square inch (0 to 69 feet of water) with an accuracy of +/-0.05% throughout the range. Water levels in OBS-A were measured manually with an electronic tape (at intervals of one hour) to verify the accuracy of the data logger; water levels in OBS-B were not measured manually because of condensation on the well casing that prevented accurate readings. Discharge from the public works well during the aquifer test was directed down a local hillside. The hydraulic conductivity of the surficial sediments was assumed to be suffi- ciently small to disregard potential recharge to the Prairie du Chien-Jor- 7 dan aquifer from this surface dis- charge. Atmospheric effects on water lev~ els during the test were not considered in the analyses. The ambient baromet- ric pressure measured at Minneapolis- St. Paul International Airport, located about 20 miles northeast of the aquifer test site, did not change during critical phases of the test. During the first four hours of the test, when most of the drawdown occurred, the barometric pressure was constant at 1,026 milli- bars. During the fifth hour of the test the barometric pressure increased to 1,027 millibars and then gradually decreased to 1,011 millibars by the end of the drawdown phase of the test. AQUIFER-TEST RESULTS Pre-test water levels did not show visible effects from changes in baro- metric pressure. Water-level changes that were within a range of one foot during the pre-test period were proba- bly related to pumping of local domes- tic wells. Although the potential effects of pumping local wells on water levels in the observation wells during the test were not determined, these effects are assumed to have been insignificant. --~;, The drawdown curve for OBS-A were automatically matched by AQTESOLV, a computer software package developed by Geraghty & Miller, Inc., to various type curves derived by Neuman (1972,1974, 1975). The Neuman (1974) type curves are valid for unsteady flow to a well in an unconfined aquifer with delayed gravity response and are based on the following assumptions: (1) the aquifer is homogeneous, unconfined, infinite in areal extent, and uniformly thick; (2) the water table in the aquifer is horizontal prior to pumping; (3) ground-water with- drawal from the pumped well is at a constant rate; (4) the specific yield is at least 10 times larger than the storat- ivity; and (5) storage of water in the I I pumped well is negligible (small diameter well) (Neuman. 1975). AQTESOLV corrected for partial pen- etration of the aquifer by both the pumped and observation wells. The drawdown equation given by Neuman (1974) is: s = 4~T W(uA, us' (3) (1) where W(u~, uB, (3) is the well function for the aquifer, and 2 r SA UA = 4Tt (2) 2 r Sy Us = 4Tt (3) 2 ~ = :2~v (4) h where s = drawdown, Q = pumping rate (ft3/d), T = transmissivity (ft2/d), r = radial distance from the pumping well to the observation well (ft), SA = the volume of water instan- taneously released from storage per unit surface area per unit decline in head (elastic early-time storativity) ( ft31ft3), Sy = the volume of water released from storage per unit surface area per unit decline of the water table (specific yield) (ft3/ft\ t = time (in days), Ky = vertical hydraulic conduc- tivity (in ftld), 8 Kh = horizontal hydraulic con- ductivity (in ft/d). and b = initial saturated thickness of the aquifer (in ft). Drawdown in OBS-A was detected about 2 minutes after the start of pumping. The total drawdown was slightly greater than 9 feet. The type curve for J3 = 0.013 best fit the early- time drawdown data for OBS-A (fig. 4). Transmissivity and storativity were calculated to be 6,267 tt2/d and 1.195 x 10-4, respectively. These calcula- tions describe the hydraulic properties. ofthe Jordan Sandstone part oftl)e aquifer. Determination of specific yield, which requires late-time draw- down data. was not done because of the short duration of the pumping period. The ratio of the vertical hydraulic conductivity to the horizon- tal hydraulic conductivity of the Jor- dan Sandstone was 5.29 x 10-4. The horizontal hydraulic conductivity of the Jordan Sandstone was 31 ftld, based on a saturated thickness of 204 ft. Drawdown was detected in OBS- B about 40 minutes after the start of pumping. The total drawdown was about 0.32 feet. These results indicate a hydraulic connection between the pumped well and OBS-B. The rate and duration of pumping were insufficient to cause drawdown in OBS-C. There- fore, the hydraulic connection of the pumped well to OBS-C could not be evaluated from the test results. .----.-r.-.-......-.----...I....-..--.--------....-............---...-------. 10 7 5 4 3 2 I j I ! j Match point 0.7 0.5 0.4 0.3 -.' -.' tu 0.2 w LL ~ $ z 0.1 0 ~ 0 0.07 ~ , 0 0 0.05 0.04 0.03 0.02 0.01 Type curve 0 Data point Q w(u) T = 4ns = 6,300 square feet per day Match point values: W(u) = 0.68 s = 1.0 feet s = UA:Tt = 1.2x 10-4 r U 1 fA. = 367 t = 1.0 days 0.007 0.005 0.004 0.003 0.002 ~ = 5.3 X 10-4 p= 0.013 0.001 0.0001 0.001 0.D1 0.1 TIME (t), IN DAYS 10 Figure 4.

A public works well completed in the Jordan Sand- stone part ofthe Prairie du Chien-Jordan aquifer was pumped at 600 gallons per minute for 57 hours. Drawdown was monitored in three observation wells located near the pumped well. These wells were open to: (1) the Jordan Sandstone, the principal unit of the aquifer; (2) the Prairie du Chien Group, a secondary, carbonate-rock unit of the aquifer; and (3) a confined, glacial-drift sand aquifer located in a local bedrock valley about one mile east of the pumped well. Type curves developed by Neuman (1974) were used to analyze drawdown data for the observation well com- REFERENCES -~' -~.

Analyses of results from the drawdown phase of the test indicate that the Jordan Sandstone had a transmissivity of6.267 tt2/d. a stor- ativity of 1.193 X 10-4, a horizontal hydraulic conductivity on 1 ft/d based on a saturated thickness of204 ft. and a ratio of vertical to horizontal hydraulic conductivity of 5.29 x 104. Analyses of the test results furthermore indicate that the pumped well is hydraulically connected to the Prai- rie du Chien Group observation well, which had a total . drawdown of about 0.32 ft. The duration and rate of pump-' ing were insufficient to cause drawdown in the observation well completed in the confined, glacial-drift sand aquifer: thus, a hydraulic connection of this well to the pumped well was not indicated.

I have found the information is based largely on speculation and misrepresentations of the facts in this matter concluding this petition is lacking any credibility. In response to the Memorandum from the Shakopee Mdewakanton Sioux Community (SMSC) Land & Natural Resources Department produced by Stanley Ellison, I have the following to offer. Transportation Analysis _The information contained within this sec_tion has been_prQd\!ced based solely o~. assumption without supporting data veflfying or substantiating their claims. I find the scenarios to be exaggerated, incorrect and without merit. The SMSC has produced this information without any formal experience or professional background to support their claims. The City of Prior Lake has conducted its own review of the transportation to and from this site and found the existing roadways will adequately handle traffic generated from our operation. Water Analysis Contrary to comments made in this section by Mr. Stanley Ellison, Ryan Contracting has clearly stated within our application that a well will not be installed nor used for our operations. Furthermore, Ryan Contracting has elected to amend. its CUP application stating, " All water used for dust control on our project will come from an off site source." Again, contrary to statements made by Mr. Ellison, Ryan Contracting has included within its application a spiWrelease contingency plan produced by the MPCA. Contrary to what Mr. Ellison has eluded to, Ryan Contracting will not be dewatering on this project in any form. The City of Prior Lake has conducted its own review of this issue and found the information contained within our application to be acceptable Additional Issues The end use of this property will be returned to agricultural use. At this time, the property is outside of the MUSA boundaries. A plan to develop this land to a residential development would be premature without knowing exactly when, where and how the trunk utilities and roadways would be provided for this property. The current property owners have expressed they would like their property returned to agricultural use. 8700 13th Avenue East Shakopee.

As you are aware, the MPCA requires a mandatory EA W to be performed for all gravel operations of 40 acres or more. Mr. Ellison has stated, " This site contains approximately 50 acres ". This statement is simply false and misleading. The proposed site is comprised oftwo separate parcels for a combined acreage of 29.604 of which we have clearly shown 13.12 acres will be affected by our operations. Contrary to what Mr. Ellison has eluded to, Ryan Contracting is strictly limited to the plans we have submitted to the City. Furthermore, Ryan Contracting has performed soil borings on this property and found we are limited only to the area we have proposed because the sand materials do not extend beyond the proposed plans we have submitted. Ryan Contracting has contacted the MPCA regarding any permits that may be required, the MPCA has informed us that a general NPDES general storm water permit will be required as with all proj ect over 10 acres in size. Ryan Contracting will secure this permit prior to commencing any operations. Ryan Contracrmg has also stated within its application, a washing plant will not be used.

As stated previously, the proposed site is comprised of two separate parcels for a combined acreage of29.604 of which we have clearly shown only 13 .12 acres will be affected by our operations. Contrary to what Mr. Ellison and Mr. Fontaine have eluded to, Ryan Contracting is strictly limited to the plans we have submitted to the City. Ryan Contracting has no intent of con1:iIiuing our operations beyond what has been proposed within our CUP application. Ryan Contracting is strictly limited to the plans, boundaries and conditions we have submitted to the City in our application. _._Contrary to what Mr.]' ontaine has stated, RYlql Contracting will not be dewatering on this site in any form. Ryan Contracting has elected to amend its CUP application stating, " All water used for dust control on our project will come from an off site source." Water from the sediment basins will not be extracted in any form for dust control. A washing plant is not part of our operation as stated in our CUP application. The City of Prior Lake has conducted a thorough, fair and unbiased review of our proposed project and found there will be no adverse affects caused as a result of our operations. Traffic Control Again, Mr. Fontaine has provided false and misleading information on the affects of our operations on public roads. The information contained within this section has been produced based solely on assumptions and speculations without supporting data verifying or substantiating their claims. I find these scenarios to be exaggerated, incorrect and lacking credibility. The SMSC has produced this information without any formal experience or professional background to support their claims. The City of Prior Lake has conducted its own review of the transportation to and from this site and found the existing roadways will adequately handle traffic generated form our operations. . Scott County has also had the opportunity to review our CUP application and found no objections to our proposed use of this property. Scott County has also stated that County Road 42 will adequately handle traffic from our operations. Water Resources & Wetlands The property in question does not contain any wetlands. However, there is an adjacent wetland over 200 feet in distance from our operations. Furthermore, this adjacent property has a substantial wooded buffer separating the wetland from our operations. The wooded area also has a natural upland ridge preventing water runoff from entering or discharging from this. wetland. The City of Prior Lake haS reviewed this issue and found no adverse impacts will be caused by our operations. Drinking Water Protection Again, contrary to what Mr. Ellison and Mr. Fontaine have eluded to, Ryan Contracting has stated within our CUP application that a well will not be installed or used as part of our project. . Furthermore, Ryan Contracting has elected to amend its CUP application stating, " All water used for dust control on our project will come from an off site source." -.' -.' Again, contrary to statements in this section, Ryan Contracting has also included within its application a spilVrelease contingency plan produced and approved by the MPCA. Boiling Springs and the Savage Fen The Boiling Springs and the Savage Fen are over 3 miles from our proposed project. The sheer mention that these resources will be affected by our operations is ridiculous and lacking credibility. Dust Ryan Contracting has adequately addressed this issue in our CUP application. Ryan Contracting has implemented known standards in controlling fugitive dust particles and agreed to make every effort possible to control dust on this project. Lighting As agreed upon with the City of Prior Lake, no artificial lighting will be used on this site. Noise Ryan Contracting will operate at acceptable levels as stated in our CUP application and as approved by the .MPCA. Aesthetic Impacts and Restoration Again, Mr. Fontaine has clearly failed to provide accurate information; instead he has made false and nrisleading statements regarding this issue. Ryan Contracting has clearly provided undisputed information detailing benning, vegetation, shielding and restoration of this property within our CUP application. Mandatory EA W Mr. Fontaine has stated" and because Ryan Contracting may to be impermissibly attempting to avoid an environmental review by improperly segmenting its proposed project in order to fall below the 40 acre threshold for a mandatoryEA W. " This statement along with numerous other statements throughout this document are simply false, and misleading. As stated previously, the proposed site is comprised of two sep~te parcels for a combined acreage of29.604 of which we have clearly shown only 13.12 acres will be affected by our operations. Contrary to what Mr. Ellison and Mr. Fontaine have eluded to, Ryan Contracting is strictly limited to the plans we have submitted to the City. Ryan Contracting has no intent of I I r --T continuing our operations beyond what has been proposed within our CUP application. Ryan Contracting is strictly limited to the plans, boundaries and conditions we have submitted to the City in our application. Summary Ryan Contracting has made every attempt to comply with and address all sensitive issues regarding our CUP application. However, Ryan Contracting will not tolerate an exacerbated Petition for an EA W based on Mr. Ellison and Mr. Fontaine's false representations of the facts in this matter. It is clear, the Shakopee Mdewakanton Sioux Community holds the general public to a much higher standard than they hold themselves. The Shakopee Mdewakanton Sioux Community has owned and operated their own gravel pit directly adjacent to our proposed project for over ten years now without the proper governing permits. (See attached exhibits A) Ryan Contracting has proposed a small gravel operation excluding dewatering, washing, crushing and recycling of materials. If our CUP application is approved, Ryan Contracting is committed to abiding by the conditions, plans and boundaries. we have submitted. However, if in the event Ryan Contracting is forced to perform an EA Won this project, Ryan Contracting reserves its right to revise its application to recover lost revenues and costs incurred. The City of Prior Lake has based their recommendation of approval based on the facts in this matter. Ryan Contracting fully expects approval of this project without prejudice.

Prior Lake, MN. 55372 Re: Ryan Contracting Co., CUP Application Dear Mr:.Boyles In response to a number of issues that have come to light in the last week, I have the following information to add to our Conditional Use Permit application. 1) Ryan Contracting proposes to operate a private gravel pit not oPen to the public. 2) Ryan Contracting will provide the city staffwith revised information prior to issuance of the CUP. The revised information will include but not limited to the following information as discussed at thewm~h~. . A) Revised pond calculations B) City right of entry C) Revised landscape plan D) Issue the Letter of Credit. 3) Ryan contracting will not be operating during nighttime hours. 4) Ryan Contracting will not be operating a rock crushing machine. 5) Ryan Contracting will not be operating a washing plant. 6) Ryan Contracting will not be installing a well. 7) Ryan Contracting will not be using any type of artificial lighting. 8) Ryan Contracting will not dewater in any form on this project. 9) All water used for dust control will be imported from an offsite source. 10) Ryan Contracting will not be recycling material. 11) Under our Cup application, the City will review this permit on an annual basis to evaluate compliance with the conditions of the CUP. 12) In 1997-98 Ryan Contracting had secured an approved grading permit allowing the removal of ~ material from this property. The City of Prior Lake revoked Ryan Contracting's approved grading permit while allowing an adjacent property owner and contractor to mine sand material from their property for the County road 21 project located within the City of Prior Lake. Ryan Contracting suffered severe financial harm as a result of the revocation of our approved grading permit. At this present time Ryan Contracting has voluntarily decided to comply with the City of Prior Lake's 8700 13th Avenue East Shakopee.

In the event Ryan Contracting is denied its CUP as allowed by City ordinance or an EA W is required, Ryan Contracting will revise its application to include any or all of the above items. Furthermore Ryan Contracting may seek legal action to ensure proper handling and compliance of this matter as well as legal action to recover lost revenues and/or costs incurred as a result of actions by the City of Prior Lake. 13) During the Workshop meeting, the proposed Church development had been discussed and the impact of the CUP on the Church property. Ryan Contracting has meet with Church representatives and believes both parties can benefit from our CUP. At this time the Church representatives have only a conceptual design. After reviewing the conceptual design, it is our opinion the proposed development may take as long as five years to construct. Ryan Contracting will work closely with the church on its needs for aggregate materials and or site development. 14) In response to the Petition for an EA W. Ryan Contracting has responded to Mr. John Larson with the Environmental Quality Board on this issue. We have supplied you with a copy of this letter dated January 18,2000. It is the Position of Ryan Contracting that the Petition produced under the :llirection of the Shakopee Mdewakanton Sioux Community is misleading, incorrect, prejudice and lacking any credibility. It is apparent, the Shakopee Mdewakanton Sioux Community holds the general public to a much higher standard than they hold themselves. The Shakopee Mdewakanton Sioux Community has owned and operated their own gravel pit directly adjacent to our proposed project for over ten years now without the proper governing permits.( see attached exhibit A ) In summary Ryan Contracting believes it's CUP application falls within the parameters of the City Ordinance allowing extraction of aggregates. Ryan Contracting is willing to commit and leave our application unchanged if our CUP is approved within the next 30 calendar days. Please feel free tocoIitact me anytime should you have any further concerns.

The attorney for the Sioux Tribe informs me that the City of Prior Lake will apparently consider approval of a Conditional . Use Permit for a new Gravel Pit on 50 acres tonighi. The tribe had been worried about this I$sue and had thought that there were to be Some more meetings on the subject before final action. They were surprised that It came up for final action so quickly. The potential water use for this operation is referred to as being under the amount which would require a DNR permit. Looking' at this' localiorl' on a map, I'm sceptical that this could end up being true. Most gravel pits use quite a bit of water - both dewatering and washing. -s~... The City has a PWS well very close to this proposed operation and the Sioux PWS wells are also not far away. The gravel pit Is apparently within the wellhead protection zone for the Tribe's well (and very likely for the Prior lake well also). Not to mention that any large use of water in that area may be detrimental to lakes, wetlands and possibly even Boiling Springs and Savage Fen. There is not enough time for us to evaluate these possible Issues before tomlght, so is there a.nyway we could get a comment over to the City'? I will fax down the attorney's writeup that requests the city to do 8n EAW because it explains the tribes viewpoint on this Issue. Apparently the City can decide, even after receiving the petition requesting an EAW, that none is needed and proceed directly to consideration of and approval of the CUP - at least that's what the attorney is worried about. So, here's a possible comment: The Division of Waters is concerned that operation of a gravel pit as proposed may required the appr'opriation of water for dewatering or gravel washing. Because of the location of the proposed gravel pit, any additional uses of water In the area should be studied prior to Implementation, lest there be detrimental impacts on nearby water supply wells, lakes, wetlands, or other valued resources such as springs or calcareous fens. Therefore the Division of Waters would SUpport a request that an envirol1mental assessment worksheet be . . prepared. cc: Pat lynch I I SEN1( BY: DNR METRO; 1-18- 04:26PM; 6127727573 .,> #1/2 facsimile TRANSMITTAL COVERSHEET Metro Region Depar1m~nt of Natural Resources DiVision ofWalers ..

I did receive a packet of information from Dorsey & Whitney representing the Shakopee Mdewakanton Sioux Community (SMSC) in regard to an EA W petition. From this information, it should be stated that McKenna Road in the City of Shakopee was recently upgraded and was only built to a "7 ton" design standard. Any hauling of material on this road would be restricted to a 7 ton loading. If you have any questions in regard to this letter, please feel free to call me.

R22W. in Prior Lake. We have received a copy of the materials submitted by Dorsey & Whitney LLPon behi'l1f of the SMSC petitioning for an EA W for this proposed mining operation. We support the petition for an EA W for the following reasons. This area is identified in the Minnesota Geologic Atlas of Scott County as lying above the Prairie du Chien-Jordan aquifer. The Prairie du Chien aquifer is within the Shakopee Oneota dolomite formation. Scott County well testing records show wells within this formation north of the proposed site to already be impacted by nitrates. The area immediately north of the proposed site, which lies at a lower elevation and thus lacks the protective soil covering over the bedrock, has been identified as being highly susceptible to ground water contamination. The soil covering is what protects the underlying Prairie du Chien - Jordan aquifer from surface contaminants. The upper terrace soils demonstrate this protective ability. The upper terrace areas will be looked at for location of future Jordan aquifer wells for Shakopee. An existing large community well lies immediately north and downgradient on the water table from the proposed site. Any operation that removes this protective soil covering is likely to degrade the protective ability of these terrace soils allowing surface contamination from storm water runoff etc. to more readily enter and degrade the aquifer. Scott County well records show a well on the proposed site that demonstrates a layer of protective clay soils within the top thirty feet and subsequently 110 feet of sand and gravel to the top ofthe Shakopee Oneota dolomite. Removal of the protective clay cover and exposure ofthe sand and gravel would allow for relatively rapid infiltration of surface contaminants. An Equal Opportunity/Safety Aware Employer I I T-- Ms. Jenny Tovar January 24, 2000 Page 2 Scott County well records also show several sand and gravel wells in this area though the McKenna well demonstrated no water was hit until the Jordan formation. This suggests a complex geology in the area with some perched gravel aquifers providing water supply. A major buried bedrock valley that extends from Prior Lake north toward the Minnesota River lies very near the proposed site. There are likely unmapped sub-valleys entering the major valley that suggest an even more complex hydrogeology in this area. A gravel mine in this area could have lasting negative impacts on the hydrology ofthe area and impacts on private, community and municipal wells. Scott County recently became responsible for enforcing the State Individual Sewage Treatment System (ISTS) rules within the City of Prior Lake. Any development, which requires manageme~. of domestic wastewater within the unsewered area of the City, must;iherefore, be 'submitted for our review. This would include projects like this one that propose to accommodate domestic wastewater by holding tanks or portable toilets. The State ISTS rules which Scott County has adopted identify holding tanks and portable privies as alternative methods of managing domestic wastewater. Scott County has only allowed such alternatives to be used for seasonal uses or as a last resort for existing failing sewage systems. We would also like to note that disturbance of existing soils would preclude the use ofISTSs in the disturbed areas in the future. The proposal suggests that mining would be limited to an extent below the threshold requirement for an EA W. We prepare all of the EA Ws on projects for the Township areas of the County and have found it prudent to pay close attention to the possibility of Phased actions. Mining operations where there is adjacent land that has similar resources, especially if it is under the same ownership should be considered as very likely to result in subsequent requests for expansions, which in total may exceed the threshold for an EA W. The EQB's "Guide to Minnesota Environmental Review Rules" is very helpful in this regard. It is available in booklet form from the EQB and is also available on their Website. We recommend that Prior Lake order an EA W for this project and direct the proposer to retain a qualified hydrologist to assess the potential impact to the area aquifers. Such an analysis should include the establishment of a better understanding of the bedrock topography in the surrounding area as well as the nature of the hydrology of the glacial deposits above the bedrock.

Prior Lake, MN. 55372 Re: Ryan Contracting Co., CUP Application Dear ~1 Tovar, In response to your questions on our CUP application, I offer the following information for your review. 1) Trafjic Volumes; I have estimated the average number of trips hauling material would be 6 trips per hour. 2) Area of Operations; I have personally performed soil borings on the property in question and found the limits of sand material available do not extend beyond the limits we have proposed. Ryan Contracting has submitted an application specifically identifying the boundaries and proposed use of this property. The speculation that our current application is just the beginning of a much larger operation is simply not true. 3) Hours of Operation; Ryan Contracting will need to have the flexibility to operate during normal construction business hours. I would suggest the City look into the normal operating hours of gravel operations throughout the metro area. I would like to discuss this matter further with you at your convenience. Please contact me on this issue, this is extremely important. Please review the above information and feel free to contact me anytime should you have any questions or concerns. ~. 8700 13th Avenue East Shakopee.

Enright, Vice President Ryan Contracting Co. 8700 13th Ave. East Shakopee,~esota 55379 ~ RE: Ryan C~ntracling Co. Conditio'nal Use Permit (CUP) Appiication Dear Mr. Enright: This letter is in response to your letter dated January 18, 2000, and addressed to Frank Boyles, City Manager for the City of Prior Lake. Your letter lists a. number of Bcth'i:ties that you state Ryan Contracting will not d~, while conducting aggregate extraction operations. Where a CUP does not include specific restrictions there is nothing stopping Ryan Contracting fcom proceeding with such activities. Without the restrictions in the CUP, Ryan Contracting could undertake unrestricted activities in its sole discretion and without requesting permission or providing notice to any other party. With regard to your regrettable comments in paragraph 14, the Community reminds you that it.is a sovereigngovemment '\Vith governmental responsibilities to its constituents. From the original date of submission the Community attempted to learn more about the CUP application. The Community also tried to state to the Prior Lake City Council the Community's and its residents' concerns regarding the proposed mining operation. Through no fault of the Community, Ryan Contracting's CUP application quickly moved through the city review process.. There was no broad public input in the CUP process. Comments on the CUP application were not sought from the City of Shakopee, Scott COWlty or the Minnesota Department of Natural Resources, even though there are potential impacts in their jurisdictions. The draft CUP ignored comments submitted by the Community and nearby residents. Whether you like it or not, the Community maintains a real interest in Ryan Contracting's proposal. Tribal members residing near the proposed mine, as individuals, expressed their strong opposition to Ryan Contracting's proposal. The tribal government stated its very real concerns over potential impacts related to the mining, There is nothing I I .f' '110; Jan. 28. 2000 3:20PM No. 2495 P. 3/3 Mr. Tyler Enright Ryan Contracting Co. January 28, 2000 Page 2 misleading in their concerns over the drinking water supply, the safety of children using McKenna Road or the quiet enjoyment of residential property. Your comments regarding the existence of a gravel ph 'on the Community's land are nothing more than an attempt to divert attention from the issues at hand. The Community does not commercially exploit its aggregate resources. The Community regulates use of the aggregate resOurce. The resource is used for tribal governmental activities and very limited use in residential projects on tribal lands. No credible comparison exists between the Community's activities and those proposed by Ryan Contracting. Even assuming the City of Prior Lake has the legal authority to allow mining near a residential area, we are aU left with a simple question. Does it make sense to allow this type of activity ina growing residential area? The Community believes tbat all reasona'"'ble people would answer "~o" to that. question. .The City of Prior Lake must consider the effects of the project on the public. In this case, that consideration must include input from the surrounding jurisdictions. After considering certain and potential impacts, it is clear that the public costs of this project greatly outweigb any benefit to Ryan Contracting or the City of Prior Lake.

Processing and loading activities are performed in the lower elevations of the pit where the side slopes, vegetation and trees will act as no.ise barriers. Ryan Contracting will operate in accordance with the noise standards established by the Minnesota Pollution Control Agency for residential areas. In addition, Ryan Contracting will be constructing a "buffer" berm on the west edge to reduce sound levels. Mining operations will begin at an elevation of 884.00 and continue down to a final elevation of 870.00. The west berm will be .constructed to an elevation of 910.00, initially allowing for a 26 foot high berm -to reduce noise. This berm will also be landscaped. Ryan Contracting will install 2 inch trees staggered an even ten feet apart on the berm. These trees will be maintained and guaranteed for as long as our CUP is active. The berm will have topsoil placed' on it. The topsoil will be seeded, mulched, fertilized, and disc anchored to provide positive turf establishment. The Minnesota Department of Natural Resources report, Industrial Minerals in Minnesota dated September 1979 states, " Typical mining equipment generates noise levels as high as 88 decibels (dB A) measured at 50 feet away from the source. Screeners can generate up to 78 dBA measured from 50 feet from the source. Table 1 describes decibels (dBA) by comparison to familiar environments. The Minnesota Pollution Control Agency has established noise standards which include noise from mining activities. The MPCA states that, "acceptable sound levels for the receiver are a function of the. intended activity in that land area" Further, these standards descn"bed the limiting levels of sound established on the basis ofpresent knowledge for the preservation of public health and welfare. These standards are consistent with speech, sleep, annoyance, and hearing. The allowable noise level standards range from SO dBA to 80 dBA.

In this case, the primary function of such streets will be to provide access. A secondary function may include through movement of intra-community travel. 1. The minor collectors must provide adequate access to abutting parcels. 2. Minor collectors should be designed to minimize through traffic. That is the layout of minor collectors should not promote diversion of traffic from arterials and major collector. 3. The intersections of minor collectors with arterials should not detract from the efficiency of those arterials. In order to prevent inefficiencies, it is recommended that the spacing between collectors be at least one-quarter mile and in multiples of one quarter mile. This will permit a minimum 30 mph operation on the arterial should signalization ever be required. 4. The=design of minor collectors should reflect the function of providing access. 5. The design of minor collectors should discourage excessive speeds. 6. Minor collectors should permit the efficient use ofland for laying out plats. 7. Minor collectors should be laid out in order to be compatible with the topography and environmental constraints of the area. 8. The design of the minor collector system should be compatible with the municipal utility plans . for the area. . 9. Minor collector streets should not be used for on-site circulation purposes. METROPOLITAN COUNCIL GUIDELINES The Metropolitan Council has issued its own guidelines in the determination of functional classification. These are published in Appendix. F of the 1996 Metropolitan Council Transportation Development GuidelPolicy Plan and are reproduced in Figures B-1 through Figure B-6.

This property is owned by Richard McKenna and Joseph and Carolyn Kinney. On November 8, 1999 the Planning Commission recommended the City Council approve the CUP with conditions. On December 6, 1999, the City Council continued this request to January 18, 2000 to allow for a workshop to be held regarding the request. Current Circumstances: On January 3, 2000, the Planning Department discussed the request with the City Council at a scheduled workshop. Additional information requested by the Council included researching other cities for combustion engine hours of operation, adding a stipulation regarding right of entry for completing improvements if necessary, and providing information regarding the source of the Department of Health's 50 foot gravel pit and aquifer separation. . Attached is a copy of the December 6, 1999 staff report, which the Council received as part of its workshop materials, detailing the request and staff review. Councilmembers have previously received a complete copy of the petitioners application. Let staff know if additional copies are needed.

Construction and related equipment limited to 7 a.m. to 10 p.m. weekdays and 9 a.m. to 9 p.m. on weekends and Holidays. Mining Operations required CUP with noise control plan including location of all occupied structure within 1000 feet and a decibel plan indicating noise levels at 5 decibel increments. City of Savage- Mining Permit required (similar to CUP). Hours of operation specific to mining activities and location of operations. Prior Lake Aggregates is limited to hauling between 7 a.m. and 10 p.m., crushing is limited from 7 a.m. to 10 p.m. and washing is limited from 7 a.m. to 12 midnight. If the specific activity does not generate noise, then the hours are expanded. If there are few occupied structures, then hours of operation would be more liberal. Considered on a case by case basis. ~'!-:.~ City of Lakeville- Mining Permit is required (similar to CUP). Hours of operation are considered on a case by case basis depending on surrounding uses. If there are no occupied structures in the vicinity, then there are no restrictions on operations. If there are residents close by, then hours of operation limited to reasonable times to satisfy any complaints from the neighborhood as determined by Council. City of Rosemount- Mining operations not permitted in residential zoned or guided districts; Mining Operations require Mining Permit. Hours generally restricted from 7 a.m. to 7 p.m. Mondays through Saturdays with no operations on Sundays. The Council can limit holidays and further limit hours depending on proposed operations and adjacent uses, considered on a case by case basis. Staff feels the hours of operation (6 a.m. to 8 p.m. weekdays and 8 a.m. to 12 noon) are consistent with the ordinance and reasonable as recommended by the Planning Commission. The ordinance allows combustion engines to operate from 6 a.m. to 10 p.m. weekdays, between 7 a.m. and 10 p.m. on Saturdays, and from 8 a.m. to 10 p.m. on Sundays. The hours of operation as stated in the resolution should not cause detriment to adjacent properties. Should problems arise, they can be considered upon review of the CUP on an annual basis. The right-of-entry requirement has been added to the resolution (italics). Staff has contacted the Department of Health (Bruce Olson) regarding the apparent 50-foot gravel pit and aquifer separation. There is no separation requirement from the bottom of a gravel pit to the aquifer. The Department of Health would like to performance standards f:\dept\planning\99files\99cup\99-075\99-075cc2.doc Page 2 (conditions) such as no large amounts of fuel stored on site and measures taken to prevent public from dumping on site (secured gate or fence). The City Engineer concurs with this recommendation. It would be in the best interest to removal the on site fuel storage. Fueling could take place from portable fuel trucks or off site. This would eliminate any possible contamination and not significantly alter the operation of the gravel pit. This condition has been added to the resolution (italics). A condition regarding securing the site from the public with a gate/fence has also been added to the resolution. .~. .~. Conclusion: Planning Commission and staff have concluded the proposed excavation of sand and gravel is reasonable and not detrimental to the community. The Planning Commission and staff recommend approval of this request subject to the following conditions: These conditions must be met prior to the recording of the resolution: 1. A one for one replacement of trees removed, (42 caliper inches) is to be completed as part of the reclamation and staging plan. Landscaping plan to indicate this additional replacement. Plantings are to be installed upon completion of phases. 2. Landscaping of 1 tree per 10 lineal feet of berm is to be installed as per item 7 on Recapitulation of CUP Application submitted by Ryan Contracting. A complete landscape plan is to be submitted including these trees and the additional 10 perimeter trees as shown on the proposed landscape plan. Plantings are to be installed upon completed of phases. 3. Driveway from the public street to the parking lot is to be hardsurfaced (paved) and shown on the plans. 4. Screen parking area with additional plantings. This is to be shown on a revised landscaping plan. 5. Revise storm water calculations per Engineering Memo dated 11/19/99. 6. .

CONTRACTING ON PROPERTY LOCATED IN THE SOUTH EAST QUARTER SECTION OF SECTION 22, T 115, R22, LOCATED ON MCKENNA ROAD History: On September 29, 1999, a completed application was received for the excavation of sand and gravel from property located in the SE ~, Section 22, Township 115, Range 22. This property is owned by Richard McKenna and Joseph and Carolyn Kinney. Due to an error in the legal description provided and upon recommendation of staff, the Planning Commission opened the public hearing on October 25, 1999 and continued it to November 8, 1999. On November 8, 1999 the Planning Commission recommended the City Council approve the CUP with conditions. Ryan Contracting is proposing to operate a sand ~d gravel mining operation. The operation will consist of mining and processing including descreening, stockpiling, and sale of product. Aggregate washing or operation of an asphalt plant is not a part of this operation. Ryan intends to operate at the site for approximately 10 years and remove 500,000 cubic yards of materials. The materials mined will be used for road construction and general' fill. The operation will run from 6 a.m. -8 p.m. Monday through Friday and 8 a.m.-5p.m. on Saturdays. Attached is a 5-page submittal from Ryan Contracting specifying the details of the proposed operation. Current Circumstances: The subject site consists of approximately 30 acres with 13 acres included in the mining plan. Section 1101.509 Grading, Filling, Land Reclamation, Excavation requires a Conditional Use Permit for excavation of more than 400 cubic yards. An Environmental Assessment Worksheet is not required by statute. The City may, however, require one be completed.

The Issues: The proposed Conditional Use Permit should be reviewed in accordance with the criteria found in Section 1108 of the City Code and Section 1101.509. Section 1101.509 is the provision on Grading, Filling, Land Reclamation, and Excavation. The criteria are shown below: City Code 1101.509 (2) Excavation. -~. -~. Excavation of material exceeding 400 cubic yards of sand, gravel 1 or other material from the land shall be permitted only by CUP. The permit application shall include, but is not limited to, a site plan which shows the finished grade of the land after the excavation has been completed, the effect of the proposed excavation upon the community and the adjacent land, the type of material to be extracted from the land, the type of equipment to be used, the period of time' the excavation operation will be conducted, plans for implementation of measures to guarantee safety of the site and the excavation operation, plans for rodent and other animal control, fire control, general maintenance of the site and adjacent area, providing for control of material hauled to or from the site, and controls to be employed to limit the effect of wind or other elements on the site and the material extracted from the site. The permit application shall include a plan which shows the routes of trucks moving to and from the site to remove material from the site, an inventory of significant trees on the site, and other pertinent information necessary to the decision whether to approve the CUP. No permit shall be granted for a period longer than 12 months. The CUP shall impose conditions upon the owner of the land to be excavated and the person performing the excavation operation which will prevent damage to the community and adjacent landowners during the course of the excavation operation. Those conditions may impose restrictions in all areas affecting the excavation operation and the City may require a Letter of Credit to insure the conditions imposed and the completion of the work will be performed in the manner described in the plan and CUP. The issues listed below are responses to the ordinance criteria and to the information discussed at the November 8th Planning Commission public hearing. The notebook dates November 19, 1999 provides the complete Ryan application with all amendments made. \ \fs 1 \sys\dept\planning\99fiIes\99cup\99-075\99-075cc.docPage 2 1. Submit a landscape plan prepared by a registered landscape architect, with one planting per 40 feet of site perimeter, as required' by City Ordinance. City Ordinance requires 1 tree per 40 feet of site perimeter. 90 Trees are required to be planted on the site. Credit is given for existing materials. There are 94 existing trees on site meeting the size and species of the Ordinance. Only one of these trees is to be removed as part of the excavation operations. Since the remaining 93 trees will be preserved, no additional plantings are required as a part of the Landscape Ordinance. 2. Submit a tree inventory and a tree preservation plan indicating the specific trees to be removed and replacement as required per City Ordinance. -~. -~. There are 1,540 total significant caliper inches on the site. 25% or 345 caliper inches can be removed without replacement. The applicant is proposing to remove one 42-inch tree or 3% of the total caliper inches. The Tree Preservation Plan meets the ordinance. 3. Submit expanded reclamation plan indicating how the area will be graded and reclaimed so as to be suitable for future residential use. A staging plan for reclaiming the site as it is completed must be a part of this. The site should be restored with top soil, seed and additional landscaping to control dust as soon as possible after staging areas have been mined. The applicants have provided letters from the property owners stating their future intended use is agricultural. The property owners are satisfied with the future reclamation as it relates to their future proposed use. At this time, until utilities are available the proposed future use of agricultural is reasonable. The Comprehensive Land Use Plan designates this property as RLIMD (Low to medium density residential). A future residential development will be possible on the site as slopes will not exceed 3:1. 4. Submit a site plan indicating proposed structures (including temporary restroom facilities), and fixed equipment with setbacks and proposed fueling areas. Any fueling areas and tanks should be located on an impervious surface and meet structure setbacks. Specifications for the parking area should be submitted and compliant with City Code requirements (paved with curb) and setbacks indicated. Parking area and equipment storage areas should be screened. Fixed equipment and parking will not be permitted over a lot line and must meet all required setbacks. A \ \fs 1 \sys\dept\planning\99files\99cup\99-075\99-075cc.docPage 3 II --r" ..~---~....._- --_._.~ ...................-..--.. contingency plan must be submitted and approved by the City Engineer for properly handling all fuel spills related to fixed tanks or equipment. The screen plant is 150 feet from the nearest property line and the parking area is 100 feet from the nearest property lines. This exceeds the minimum required setbacks per ordinance. Specifications on the fuel storage container have been provided. It is an enclosure which prohibits leaking into the ground by design. The applicant will pave and provide curbing of the parking area. All fixed equipment will meet setbacks. The parking area needs to be screened. This is an outstanding condition made a part of the resolution. -~. 5. Submit a plan for continual monitoring of water quality. A report shall be submitted prior to beginning mining, with' reports submitted to the city on a regular basis. A plan for maintaining the current quality of water in the area must be submitted prior to beginning work. -~. A letter from Ryan states annual testing of the wetland will be submitted to the City. An attached letter from Braun Engineering lists the chemicals to be monitored. This is acceptable and is made a condition ofthe resolution. 6. The storm water calculations were prepared by an engineer . and the drainage plan was prepared by a land surveyor. The grading plan should clearly indicate property lines and proposed grades and berming. The grading plan should be revised as follows: Additional silt fence is needed on the SW corner of the site. Hydrologic/hydraulic calculations needed for 2,10 & 100 year event storms showing existing and proposed run-off rates from the site in cubic feet per second (CFS), pond slopes below normal water level are to be 6:1 slope, 4:1 slopes required above the normal water level of the sediment ponds, all other grades cannot exceed 3:1. A revised grading plan was submitted and is acceptable. However, hydrologiclhydraulic calculations submitted are inadequate (Memo 11/19/99 from Sue McDermott). The proper information (direction and rate of run-off) must be submitted prior to the recording of the resolution and is a condition of approval. 7. DNR issues include protection of DNR wetland #70-247W. Water use for dust control of greater than 10,000 gallons per day or 1 million gallons per year requires a DNR permit. Provide a schedule with quantities and specific water sources for dewatering. \ \fs 1 \sys\dept\planning\99fi1es\99cup\99-07 5\99-075cc.docPage 4 The operation of the pit cannot result in the drainage or other degradation of the DNR protected wetland. This is a condition of the resolution. 8. A letter of credit must be submitted. The LOC will be for 125% of landscaping costs, road maintenance/reconstruction, and environmental testing/inspections to ensure compliance with the CUP. Estimates or bids must be submitted for the required landscaping. Estimates for road maintenance and environmental testing must also be submitted and approved by the City Engineer. An estimate has been submitted and is acceptable. A LOC acceptable to the City Attorney must be submitted prior to recording the resolution. This is a condition listed on the resolution. -,;... 9. Submit plan for dust control. Water what, where, when? The applicant has submitted a letter identifying dust control methods. They will water the site within 24 hours of city notification if needed. This is a condition in the resolution. 10. Submit plans for maintenance, upgrading, clean up, and safety of McKenna Road/CSAH 42. The applicant met with the engineering staff regarding this concern. The applicant intends to maintain the current condition of McKenna Road throughout the excavation. A LOC will be posted with the city for maintenance and/or repair. The condition of McKenna road will be reviewed on an annual basis as a part of renewal of the CUP. The applicant is responsible for maintain the current condition of McKenna Road. 11. The CUP is valid for one year. Renewal of the CUP is to include a staging plan to date, reclamation to date, along with water quality, road quality, wetland quality, and air quality reports submitted by qualified professionals. This is a condition listed in the resolution. CONDITIONAL USE PERMIT (CUP) ANALYSIS: Section 1108.200 of the City Code sets forth the criteria for approval of a CUP: \\fs 1 \sys\dept\planning\99fi1es\99cup\99-075\99-075cc.docPage 5 I I [ --,--.---.---.---.... ... .... (1) The use is consistent with and supportive of the goals and policies of the Comprehensive Plan. Objective 5, under the goal of Security, is to Provide for conservation and protection of the natural environment. The policies include providing adequate regulation to prevent the development of endeavors which will create a hazard to the environment and to require developers to retain the natural environment as much as possible. The conditions set forth in this CUP address environmental hazards and require land reclarriation and site restoration. -~. -~. Another policy of the Comprehensive Plan is to require developers to retain the natural environment as much as possible. Considering the proposed mining operation, it is difficult to restore the site to a natural condition. The Landscape ordinance allows for credit for existing materials preserved and the project complies with the Tree Preservation Plan with removal of less than 25% of the total caliper inches. A condition of the CUP should require exact replacement of trees removed (42 caliper inches) to restore the natural environment as much as possible. The Comprehensive Land Use guide plan, designates the future land use as single family residential. The reclamation plan is acceptable to the property owners for their current and future agricultural use. (2) The use will not be detrimental to the health, safety, morals and general welfare of the community as a whole. Based on staff and Planning Commission review, the proposed use will not be detrimental to the health, safety, morals and general welfare of the community. Annual review of the CUP will ensure ongoing protection ofthe community. (3) The use is consistent with the intent and purpose of the Zoning Ordinance and the Use District in which the Conditional Use is located. Section 1101.509 ofthe Zoning Ordinance allows Grading, Filling and Land Reclamation as a Conditional Use within any zoning district. The conditions set forth in the Zoning Ordinance will be met with the issuance of the Conditional Use permit. (4) The use will not have undue adverse impacts on governmental facilities, services, or improvements which are either existing or proposed. \\fs 1 \sys\dept\planning\99files\99cup\99-075\99-07 5cc.docPage 6 The use will not have adverse impacts on governmental facilities, services or improvements as the applicant will be responsible for maintaining the condition of McKenna Road and CR 42 as is exists prior to the issuance of the CUP. In order to ensure this, it is necessary to require a Letter Of Credit (LOC) for the maintenance of McKenna Road. Costs related to the proposed use, such as expenses for inspections and testing, will be borne by the applicant. (5) The use will not have undue adverse impacts on the use and enjoyment of properties in close proximity to the conditional use. -.' The use will not have undue adverse impacts on the use and enjoyment of properties in close proximity as the proposed mining operation is located approximately 30 acres of which only 13 acres will be mined. The property owners have signed the application, giving their consent for the proposed use. The property to the north is agricultural in use and the nearest residence is approximately 185 feet from the proposed area to be disturbed (McKenna residence). The next closest dwelling is approximately 325 feet from the area to be disturbed. -.' Staff does not anticipate development in the area to occur until utilities are extended. Under the Comprehensive Plan, this could and will occur at some point in the future. (Staff expects this to be at least 10 years.) However, development will be driven by property owners desire to develop the area and would not necessarily be prohibited to do so under the Comprehensive Plan or Zoning Ordinance. The applicant will be responsible for inspections and testing to assure maintained quality of roads, trees, and wetlands. Costs related to the proposed use, such as expenses for inspections and testing, will be borne by the applicant. (6) The use is subject to the design and other requirements of site and landscape plans prepared by or under the direction of a professional landscape architect, or civil engineer registered in the State of Minnesota, approved by the City Council and incorporated as part of the conditions imposed on the use by the City Council. One tree per 40 feet of site perimeter is required. Credit is given for existing materials. The existing 94 trees are sufficient to meet the 90 trees required on site. A complete tree preservation plan has been submitted. 25% Ofthe total caliper inches can be removed without replacement and the applicant is proposing to remove one tree (3% of total inches). Compliance with these provisions exists. \ \fs 1 \sys\dept\planning\99files\99cup\99-075\99-075cc.docPage 7 I I '--r- ----r-------------------.. (7) The use is subject to drainage and utility plans prepared by a professional civil engineer registered in the State of Minnesota which illustrate locations of city water, city sewer, fire hydrants, manholes, power, telephone and cable lines, natural gas mains, and other service facilities. The plans shall be included as part of the conditions set forth in the CUP approved by the City Council. The storm water calculations and drainage plan were prepared by a professional engine-er. No utilities are planned such as water, sewer, electricity, gas, or telephone. Additional storm water information is needed and has been made a condition of the resolution. -......;.. (8) The use is subject to such other additional conditions which the City Council may find necessary to protect the general welfare, public safety and neighborhood character. Such additional conditions may be imposed in those situations where the other dimensional standards, performance standards, conditions or requirements in this Ordinance are insufficient to achieve the objectives contained in subsection 1108.202. In these circumstances, the City Council may impose restrictions and conditions on the CUP which are more stringent than those set forth in the Ordinance and which are consistent with the general conditions above. The additional conditions shall be set forth in the CUP approved by the City Council. Additional conditions are being recommended based on the issues addressed with specific review of City Code 1101.509 Grading, Filling, Land Reclamation and Excavation, the DNR Handbook for Reclaiming Mining Sites, staff review, and public comments received. Conclusion: Planning Commission and staffhave concluded the proposed excavation of sand and gravel is reasonable and not detrimental to the community. The Planning Commission and staff recommend approval of this request subject to the following conditions: These conditions must be met prior to the recording of the resolution: 1. A one for one replacement of trees removed, (42 caliper inches) is to be completed as part of the reclamation and staging plan. Landscaping plan to indicate this additional replacement. Plantings are to be installed upon completion of phases. 2. Landscaping of 1 tree per 10 lineal feet of berm is to be installed as per item 7 on Recapitulation of CUP Application submitted by Ryan Contracting.

Case File 99-075 Ryan Contracting is requesting a Conditional Use Permit for grading, filling, land reclamation and excavation. The applicant is intending to operate a sand and gravel mining operation. Planner Jenni Tovar presented the Planning Report dated November 8, 1999, on file in the office of the City Planner. On September 29, 1999, a: completed application was received for the excavation of sand and gravel from property located in the SE ~, Section 22, Township 115, Range 22. This property is owned by Richard McKenna and Joseph and Carolyn Kinney. Due to an error in the legal description, upon recommendation staff, the Planning Commission opened the public hearing on October 25, 1999 and continued it to November 8, 1999. Ryan Contracting is proposing to operate a sand and gravel mining operation. The operation will consist of mining and processing including descreening, stockpiling, and sale of product. Aggregate washing or operation of an asphalt plant is not a part of this operation. Ryan intends to operate at the site for approximately 10 years and remove 500,000 cubic yards of materials. The materials mined will be used for road construction and general fill. The operation will run from 6 a.m. to 8 p.m. Monday through Friday and 8 a.m. to 5 p.m. on Saturdays. Staff received necessary information on Wednesday but were unable to review before the packets went out. The staffhas since reviewed the information and felt the outstanding conditions and concerns were met. Staff recommended approval with the 5 conditions listed in the Planning Report. Tom Ryan, President of Ryan Contracting, explained the Conditional Use Permit request was to use the natural aggregate resources in the property and through the process address all environmental issues and concerns by staff. f:\dept\planning\99fi1es\99plcomm\pcmin\mn II 0899.doc 6 , I If . -..r-...--........-----.---.-..--.-- Planning Commission Minutes November 8. 1999 Comments from the public: Craig Ahlman, 13799 McKenna Road, said he did not want this project next to his property. His other concerns are the truck traffic and times of operation. It is a long and big operation for the area. Rick Palla, 13755 McKenna Road, said he and his neighbors fought a gravel pit 10 years ago when the same family was trying put In an adjoining pit. Many residents fought the proposal and won. In the end, the Dakota Community bought the land. Palla felt his weekends offwill be spent next to a mining pit. Tovar explained the surrounding properties. Palla felt there was a lot of traffic in the area right now and was concerned for truck traffic. He felt the hours proposed are unreasonable and stated no one wants to live next to a gravel pit. -~' Tovar explained the City sent notices to residents within 350 feet ofthe project. The City also sent out a review request to the Dakota Community prior to the report. There is a letter in the Commissioner's packets from the Community with their concerns. Tom Ryan, the applicant, commented they had a grading permit two years ago and voluntarily stopped mining until the City could change their conditional use permit process. Ryan said they want to be a positive force in the community. He went on to say they might be done in 3 years, hopefully they would not be mining in the area for 10 years, but it is unknown. They felt 10 years was suitable. The renewal is on an annual basis and ifthere are problems they can be brought up yearly. Concerning the hours of operation, Ryan said it is very unlikely they would be working during non-construction season. One of the conditions is no lighting. They cannot work in the dark and do not like to work on Saturdays. They are just trying to leave some leeway to work sufficiently. Evonne Anderson, 13222 Pike Lake Trail, representing the Southdale YMCA questioned the County Road 21 expansion and how it fits in the Watershed District. They are concerned with the high water at Pike Lake. Anderson also questioned the truck traffic on County Roads 16 and 42. They want to make sure there are safety precautions. Rye responded the County Road 21 alignnient will be 300 to 400 feet from the property. McDermott pointed out a letter from the Watershed District indicating they would not look at the permit until the City approves the project. Tyler Enright of Ryan Contracting explained the proposed traffic flow stating County Road 16 will not be used. The public hearing was closed at 9:12 p.m. Comments from the Commissioners: f:\dept\planning\99fi1es\99plcomm\pcmin\mn 11 0899.doc 7 Planning Commission Minutes November 8. 1999 Cramer: . Did not agree with staffs recommendation to approve. . Shepherd of the Lake Church is proposing a campus at the comer of County Road 42 and Pike Lake Trail. . That portion of County 42 and McKenna is cut down to 2 lanes and is notorious for being a danger area. _ . The Dakota Community indicated they had concerns with a nearby well. . McDermott responded the issue is addressed in Ryan's proposal and is within the guidelines issued by the Department of Health. . Does not feel this development is appropriate for the location given the other types of developments in the area. Will not support. V onhoI: . Dis-~~eed with Cramer. Felt this Conditional Use Permit is an interim use and is consistent with the Comprehensive Plan. It comes back for renewal every year. . The 11 issues in the Planning Report have been addressed. Any approval would have to address the concerns as part of the plan. . Regarding the off-site traffic and impact, Ryan agreed to maintain the road. It is also part of the condition. . Another concern is regarding noise on the site. The decibel level has been addressed and is adequate. . . This is not a permanent long term use. It is appropriate and the conditions are met. Stamson: . Agreed with Vonhof, it is a temporary use and expires within the time frame of the 2010 Plan. It is appropriate within the Comprehensive Plan. . His concerns have been addressed by staff. . One concern is the hours of operation. What are Savage's time for operation? Never had a problem with neighboring Savage's pit. Tovar responded the hours of operation are consistent with the City's combustion engine ordinance which allows lawnmowers and other types of machinery allowed within the hours. . Six p.m. deadline is more appropriate. . Tom Ryan said the reason for the hours requested is because it is consistent with the City's hours of operation. He also addressed Vonhofs concern of decibels. Their loudest decibel is in the 70 to 80 range. . Ryan said it is not their intent to occupy the pit full-time. V onhof: . Be consistent with the time and noise ordinances.

Old Business: 6. New Business: A. Case File 99-083 Chris Anderson is requesting a vacation of a portion of frontage road located adjacent to 16020 Eagle Creek Avenue. Planner J enni Tovar presented the Planning Report dated November 3, 1999, on file in the office ofthe City Planner. The Planning Department received an application from Chris Anderson requesting the vacation ofthe portion of public roadway located in front of his property. The purpose ofthe vacation is to give Mr. Anderson more property in the front yard, resulting in a private area for a future garage. While variances would be needed for a future garage, the variance request would be minimized with greater lot area. Mr. Anderson is proposing to vacate 26.50 feet of right-of-way with 13 feet being retained in a utility easement for the City. The intent of the Comprehensive Plan will be met, however, there is a public interest in retaining the entire right-of-way as platted. Planning staff recommended denial ofthe request as submitted. Comments from the public: Chris Anderson, 16020 Eagle Creek Avenue, felt there was adequate distance to the road for utilities. He would like to build a garage stating his neighbors would like to see him complete it as soon as possible. Anderson would like to expedite the process. Neighbors signed a petition in support.

INTRODUCTION - Ryan Contracting Company proposes to operate a sand and gravel mining operation within the City of Prior Lake. Ryan Contracting Co. is seeking a Conditional Use Permit from the City of Prior Lake to begin mining and processing including descreening, stockpiling, and sale of product. Aggregate washing or operatioo~of an asphalt or _concrete plant is not .a part of this operation. These activities, if required, will be performed off-site. The site is located on a combined 29.604 acres of land, of which onlv 12.91 acres are included in the proposed mining plan. The following information briefly describes our proposed use, more specific information can be obtained in our booklet submitted containing the Conditional Use Application. ll.

Containing 20 acres more or less. 3.) Names of adiacent proPerty landowners including all those within a 350 ft. radius of the property. A property owner list was generated by Old Republic Title. This list is included as Exhibit 6. 4.) Specifications of the following. using: appropriate maps, photographs and surveys: ..,~.. a. The physical relationship of the proposed site to the commWlity and existing development. The proposed site is located in the northeast portion of Prior Lake, just north of County Road 42 on McKenna Road (See Exhibit 5). Residential areas are located to the west and east of the site. The land to the north of the site is open fields with some groves of trees. The land to the south is Mr. Richard McKenna's house along with McKenna Road and field. b. Site topography and natural .features including location of water courses and water bodies. Exhibit 15 is a U.S.G.S. quadrant range map which illustrates the relationship of the site to surrounding natural features. The site topography is shown in 2 foot contour intervals. The plan also shows drainage ways and direction of surface water flow under current conditions. The plan also shows the location and description of the trees in the area of the proposed building site. c. Description and quantity of material to be excavated. Material to be mined from the site will consist of sand and gravel. The soils within the mining limits are predominately Estherville and Kingsley soils, both sandy loams forming in loamy glacial outwash over sand and gravel deposits. The Scott COWlty Geological Atlas maps the site as a primary sand and gravel resource with over 35% gravel. Approximately 500,000 C.Y. of material will be mined from this site. The type of material to be mined will be sand and gravel. Initially a phase will be opened up by stripping topsoil over a designated area. lbis topsoil will be stockpiled on site and later used in restoration. No topsoil will be sold or removed from the site. Any overburden, fine clays, and silty soils which cannot be sold or utilized by the operator will also be stripped exposing the underlying aggregate. Mining will create an active mine face with a slope liot exceeding 1:1. Perimeter slopes may be mined to 1:1 and then backfilled. to the grades shown on the mining plan. Final grades- over the base of the pit are at a minimum elevation of 870.00. Mining may occur below the depth of the grades shown on the plan in areas where good material is encountered. All material replaced below elevation of 870.00 will be structural suitable for building and will include certification of any filling. These areas would then be backfilled. as part of restoration for that 2 I I I -..--.---.... particular phase. The maximum depth of mining will not exceed elevation 850.00. The average restoration grade will be arOlmd elevation 870.00. 5.) The purpose of the operation: The purpose of the mining operation is to obtain natural aggregate for use in the construction industry. The operator will use material obtained from site to produce aggregates for road construction and general fill. 6.) The estimated time reQuired to complete the operation: The site will be active for an estimated 10-year period. The life of the site will be dependent on market demand. The site will be operated in phases. Mining will begin in the western portion of the site and progress to the east. Each year an annual report will be submitted, which will outline areas to be stripped, mined, and reclaimed during the next mining season. This will keep the City up to date on the mining progress, and rate of mining activity at the site. -.,.;", 7.) The plan of operation: Duration of MininJ! Activity: Mining activity typically occurs from March-December. The life of the mine is estimated to be 10 years. Hours of Ooeration: The site will be operated from 6:30 AM - 7:30 P.M. Monday - Friday and 8 A.M. - 5 P.M. Saturdays on a seasonal basis. Operations: Operations will be initiated by stripping an area corresponding to the first years excavation activities. The stripping will be shaped into berms along the designated setback areas. These berms will be seeded to provide screening, noise and dust abatement Material will be excavated from .the working face, desanded, and stockpiled according to the various grades of material. The initial location of the screening plant is shown on Exhibit 8. Mining will progress in a west to east direction. Conveyors may be used to feed material to the screening plant throughout the mining season. Each year, additional area will be stripped as the working face moves easterly. The screening plant is a portable plant and may be moved off of the site depending on the amotmt and location' of future contracts. Exhibit 8 shows the location of the screening plant. Noise: All equipment will be operated within the noise emission standards established by the Minnesota Pollution Control Agency (MPCA). Processing and loading activities are performed in the lower elevations of the pit where the side slopes, vegetation and trees will act as noise barriers. Ryan Contracting will op~tein accordance with the noise standards established by the Minnesota Pollution Control Agency for reSidential areas. In addition, Ryan Contracting will be constructing a "buffer" berm on the west edge to reduce sound levels. Mining operations will begin at an elevation of 884.00 and continue down to a final elevation of 870.00. The west berm will be constructed to an elevation of 910.00, initially allowing for a 26 foot high berm to reduce noise. lbis berm. will also be landscaped. Ryan Contracting will install 2 inch trees staggered at an even ten feet apart on the berm. These trees will be maintained and guaranteed. The berm will have topsoil placed On it. The topsoil will be seeded, mulched, fertilized, and disc anchored to provide positive turf establishment. The Minnesota Department of Natural Resources report, Industrial Minerals in Minnesota dated. September 1979 states. "Typical mining equipment gen~ates noise levels as high as 88 decibels (dBA) measured at 50 feet away from the source. Screeners can generate tip to 78 dBA measured. - 3 I I from 50 feet from the source. Table 1 describes decibels (dBA) by comparison to familiar environments. The Minnesota Pollution. Control Agency has established noise standards which include noise from mining activities. The MPCA states that, "acceptable sound levels for the receiver are a function of the intended activity in that land area." Further, these standards described the limiting levels of sound established on the basis of present knowledge for the preservation of public health and welfare. These standards are consistent with speech, sleep, annoyance, and hearing. The allowable noise level standards range from 50 dBA to 80 dBA. TABLE 1 NOISE LEVEL COMPARISON Decibels (dBA) Common Sounds -~. -~. 160 140 120 100 80 60 50 40 20 o Medium jet engine Large propeller aircraft, air raid siren Disco Canning plant, heavy city traffic, subway Busy office Normal speech Private office Quite residential neighborhood Whisper Threshold of hearing Exhibit 8 shows. the initial location of the screening plant, stockpiles, and haul roads which will eliminate the need for trucks to back up sounding their back - up alarms. If requested, Ryan Contracting will be willing to disconnect our backup alarms, if absolutely necessary. The screening plant will be placed at various locations throughout the pit to minimize noise to the surrounding area. Material will be stockpiled fromthe screening plant by conveyors. EQuimnent: Machinery will be kept. in good repair. Abandoned machinery, inoperable equipment and rubbish shall be removed from the site regularly. All buildings or equipment not used for a period of one year shall be removed from the site. All equipment and structures shall be dismantled and removed within 90 days after termination of the permit Natural Screenin$!: The perimeter of the site shall be screened as shown on the. aerial photo (Exhibit 18). The aerial is from Scott County Surveyors and dated 1990. The severe thunderstorms :from 1998 destroyed the trees on the east side of the pit in phases n and Ill, those are shown in the aerial. The site will be screened :from the residences to the north and west by the groves of trees. This buffer area will provide both visual screening, and noise and dust abatement. There are no residents to the east of the si~e. Water: No well will be drilled on the site or washing of aggregates; however Ryan Contracting will use the water :from the ponds on site for dust control. . Fuel Storaf!e: Ryan Contracting will be storing fuel on the site in an above ground 1000 gallon steel tank placed in a concrete enclosme. The fuel will be diesel fuel for the operating of the screening plant and the construction equipment only. The concrete enclosure will contain spills ifleakage did occur. The concrete enclosure is made by Crest and is a MPCA approved design for this exact situation. Please see the Exhibit 24 containing specifications on the enclosUre. The enclosure' will have a roof over it along with a metal chain link fence. The fuel tank will be locked when not in use. Due to the concerns from the Shakopee Mdewakaotoo Sioux CommllDity (SMSC) regarding fuel spillage, this is the best solution. The enclosme will trap fuel that is spilled or leaked from the tank and will prevent fuel from contaminating the grOlmdwater. Wrth the tank on site, this will reduce the number of refueling trips to the site thus decreasing the possibility of a: fuel spill. In the unlikely event a fuel spill would occur, Ryan Contracting would 4 --.---.--T--------.-----..----------. -- I respond by following state guidelines as outlined by the MPCA. These guidelines are included under Exhibit 24. The MPCA does not require a permit for an above ground fuel tank less than 1,100 gallons. Site Security: The gates to the site will locked when not in use. The rest of the site will be protected by the current homeowner. Currently, there is a barbwire fence and snowfence securing the site. Parkin)!: . The parking area as shown on the Exhibit 8 is for employee parking only. The surface of the parking lot will be of a gravel material like class 5. . The gravel surface will be maintained by Ryan Contracting on as need basis. The size of the parking lot will be large enough to handle five full size vehicles. The parking of the construction equipment will be next to the screen plant or nearthe center of the gravel pit. 8) Traffic & Travel routes ~~;.. The site is 10catedroughlyV-Imilenorth of County Road 42. To access the site from County Road 42, trucks will exit off County Road 42, onto McKenna Avenue, and turn onto Richard McKenna's property which is where the pit is located. Traffic from the site is reversed to County Road 42. Dust control methods will be implemented as indicated in Exhibit # 21. Ryan Contracting proposes to limit the number of trucks visible to the public on this property to 6 at any one time. Other trucks may be waiting within the pit, recessed and out of view of the public. At no time will trucks be allowed to use McKenna Road to the north for an access to this property. Please refer to Exhibit 14 for an example of signage. 9.) Drainage. Water Erosion Control. Sedimentation and Dust Control Currently the site drains to the northwest over land and off site. Min.ing will move from the west to the east with the pit floor sloping to the west maintaining this overall drainage pattern -throughout the life of the site. Erosion will be controlled be placing heavy-duty silt fence in the drain swale where the sedimentation ponds will be constructed adjacent to the mining operation and by on-going restoration of disturbed areas including topsoil placement and establishment of vegetation. Sedimentation ponds will be constructed in the northwest portion of the site to treat runoff prior to leavingthe site. These ponds will be constructed at the beginning of operation. They are designed to aCC<llIl1Dodate a 10 year; 24 hour ston:il runoff over the maximum disturbed area at any given time. Exhibit 10 contains sizing computations done by Cal Hedlund with Gorman Land Surveying, Inc. The location of the sedimentation ponds is shown on the proposed grading plan (Exhibit 1 O)~ Dust genemted from vehicle traffic will be minimized by utilizing the existing access to the site. A water truck will be used as needed to water used roads. On site processing equipment will be recessed thereby minimi7.ing the amooot of dust leaving the site. The vegetated buffer area will also reduce fugitive dust. _ Stripping operations will be conducted in as short of a time fr~e as possible. The overburden will be removed and stockpiled. The stockpiles will be seeded to reduce the source of dust. The . site entrance roads will be watered as needed. Restoration of the . site will be on going to rninimi7.e the amount of area without vegetation at any given time. Fugitive dust, dust not associated with specific processing activities, is also addressed in the sites Air Quality Permit which will be obtained from the MPCA. -5 Calcium chloride is used statewide by the State of Minnesota, counties, cities, tOwnShipS, and recommended by consultIDg engineering firms throughout the state. The use of calcium chloride on the gravel traffic routes will minimize the amount of dirt blown in the air. The screening plant will be on the floor of the proposed pit. The vegetated berms, walls and trees will act as shields minimir.ing fugitive dust. The existing trees on the west and south sides will act as a natural buffer. On the north and east of the proposed pit, the existing fields will also act as natural shields. The pr<posed berms, trees, and fields will reduce the presence of pit operations from the view of the public and residents. - Ryan Contracting Company will protect the site and adjoining surrounding properties from erosion and sedimentation. If erosion occurs off site as a result of our operation, Ryan Contracting will immediately clean up the debris at our expense and restore all damage to the surrounding properties. 10) ~~.., Tree Preservation: A tree Dventory has been performed on this site. There will be a total of three trees removed on this site as a result of our proposed use. This equates to 3.03% of the total trees to be removed. There vill be a total of70" of trees removed out ofa total of23IO" of trees surveyed by Gorman Land Surveying. The tree removal does not exceed the 25% tree removal limit, however Ryan Contracting will be planting over fifteen trees on the west berm ih addition to the ten proposed plantings shown in the attached plan. The tree plantings on the west berm will be done once the berm is fully constructed. The remaining trees shown in Exhibit # 13 will be planted at the completion of our project. The trees on the west berm will be planted within 45 days of April 15, 2000, p"oviding our CUP has been received by this date. Ryan Contracting will be planting the trees in good faith to the City of Prior Lake and the adjacent residents. The proposed trees will be maintained and guaranteed. The existing trees will be protected by means of snowfence with metal posts and will be erected past the drip line of significant trees along the mining limits. Snowfence will be maintained in place until restoration along the perimeter of the mining limits has been completed. 11.) Rehabilitation Plan: Rehabilitation of the mining area will be performed to restore the site to a stable condition, minimizing the potential for erosion, and also allowing for future development of the land. Rehabilitation will involve final grading, slope stabilization, application of topsoil and seeding and mulching. Existing grades prior to mining are shown. on the Existing Conditions Plan (Exhibit 7). Exh1bit 8 indicates the sequence and timetable of mining and the location of topsoil and overburden storage areas. Restoration grades are shown on the proposed grading plan (Exhibit 9). Existing perimeter side slopes will be mined to a maximum of 1: 1 and backfilled to a minimum of 2.5:1. The slope of the floor of the pit will be 1.00010. A minim:wn of 4" of topsoil will be placed over the graded slopes and floor of the mining area. Vegetatioo will be established. V ~getation will consist of MnDot Seed mix number 50A, a mixture of predominately Bluegrass, Bluestem, and Bromegrass. Sufficient topsoil is available on site for use in reclamation. Approximately 5 acres of the' site will be left with 2.5:1 slopes. This.area will require an average 4" depth oftopsoil. Approximately 8 acres of the pit floor area will require an average of 4"-oftopsoil. Restoration will be ongoing. Each year mined areas not utilized for processing or stockpiling will be graded to the proposed plan. Topsoil will be applied and vegetation established to minimize the amount of open area at any ~ven time. An annual operating plan will be submitted each y~. 6 II ------r- .---r------ This plan will include a map which shows areas which have been reclaimed during the past mining season. Areas to be reclaimed the following mining season will be noted as well. Reclamation of the site: The site was originally and still zoned agricultural. The site is currently outside of the Metropolitan Urban Service Area (MUSA). Mr. Richard McKenna and Mr. Joseph Kinney are currently the two property owners of this site. Ryan Contracting has a contract with these owners for the removal of this material as shown in Exhibit 10. When the pit use has been completed, Ryan Contracting will restore the land back to agricultural use. The site will have 4" of topsoil and seeding over all disturbed areas. The site will not create a pond as other pits have become. The only water in the pit will be in the sedimentation ponds that will be cleaned out as part of the restoration of the site. After completion and restoration of the gravel pit, the use will be at the discretion of the landowners. The landowners have indicated they wish to retmn the property to agricultural use. Ryan Contracting will furnish the City with a $ 50,000.00 restoration bond to guarantee restoration of this property. 12.) ...Permits: -." In addition to the Conditional Use Permit and the annual permit renewal required by the City of. Prior Lake, Ryan Contracting may also be required to obtain the following permits: . Minnesota Pollution Control Agency: National Pollutant Discharge Elimination System (NPDES) General Stormwater Perron. Ryan Contracting will be responsible for obtaining all necessary permits as required by the MPeA. Copies of required permits will be submitted to the City prior to beginning mining operations. . DNR: Department of Natural Resources will be informed, Ryan Contracting will be responsible for obtaining all necessary permits as required by the DNR Copies of required permits will be given to the city prior to beginning mining operations. 13) Maintenance of McKenna Road Ryan Contracting Company will repair and maintain McKenna Road from County Road 42 to the entrance of the gravel pit as needed at the discretion of Ryan Contracting and the City of Prior Lake. A biannual review will be set up with the City of Prior Lake to observe the conditions of McKenna Road and determine the need for repair. The condition of McKenna Road will be kept in as good as condition or better while the gravel pit is in operation. Ryan Contracting Company . will post a $ 50,000.00 maintenance bond with the City of Prior Lake to guarantee maintenance and repair of McKenna Road while our Conditional Use Permit is active. It is our understanding McKenna Road may be realigned within the next five years. The extent of repairs to this road will be negotiated with the City of Prior Lake to an acceptable level as agreed on. 14). Compliance: The site will be operated as indicated in this permit application. Any additional conditions as set forth in the permit will be adhered to. Once the operation has been established, any questions, complaints, or requests by the city or residents should be directed to either Tom Ryan or Tyler Enright of Ryan Contracting Company at {612) 894-3200. Action will be taken immediately where appropriate. Ryan Contracting Company will work in good faith to resolve any-complaints or issues related to the .operation of the mine. _ An annual report will be submitted to the city in conjunction with the annual permit renewal. The report will show limits of current mining and processing areas, stockpile areas, the next phase of stripping/mining, previous years restoration areas, the next years planned restoration a~vities, and the quantity of material removed from the site during the previous mining season - 7 15) Site Appearance Ryan Contracting Company will be operating this pit in a professional manner. The pit will siart on the west side and work to the east. TJ:le pit will be have a full exposed face from the existing ground to the proposed pit floor. The ber:ins and slopes on the proposed pit will be constructed as the pit takes shape. along with the restoration. (See Exhibit 9) The pit will be constructed in three phases over a life span of roughly ten years. Each phase will not be constructed in three and a half years, but will be constructed on need and/or supply and demand on the material available in the pit The phasing plan is outlined on how the pit will be constructed. (Exhibit 19 ) All equipment will be in operating use on the site. There will be no abandoned equipment on the site that is the property of Ryan Contracting Company. This pit is to operate in a clean and neat fashion, not to offend any of the residents in the area, property owners. or government officials. -.' Ryan Contracting will be the sole operator of this pit. There will be no other operators using this pit if granted th.e conditional use permit. Once the CUP has been received Ryan Contracting will be responsible for all activities in the pit and maintenance or repair of haul routes. 16) WETLAND # 70-247W Please refer to Exhibit 22 showing the approximate location of the wetland in relation to the.pit location. This wetland will not be disturbed in anyway by our activities. The drainage on this property nms from the southeast to the northwest The location of this wetland is directly southeast from our proposed gravel pit. There will be no drainage into the wetland, nor will the wetland be drained of water. Currently. there is a natural buffer between this wetland and our pit location. Ryan Contracting. will review this area witb the DNR, and if requested, Ryan Contracting will install heavy duty silt fence as a precaution. Currently. there is a natural land and wooded buffer between our property and the wetland. This area will not be disturbed , nor traversed in anyway. 17) Groundwater Well Head: Sanitation: , 1 The concern by the SMSC in the elevation of the floor of the proposed pit to their Public 'Water Supply (PWS) well is being taken with great concern. The elevation of the floor in the proposed pit will start at an elevation of 884.00 and may be excavated to an elevation of 850.00 with a restored elevation of 870.00. The ground water is at an elevation of 743.00 according to the Mean Sea Level (MSL.) with bedrock at 750.00 according to SC-Geo Atlas. Excavation of mined material will leave over 100 feet between the proposed pit floor and th.e Jordan Aquifer. The Minnesota Department of Health recommends at least 50 feet or more in separation. The distance between the aquifer and the pit floor is double the recommended separation distance. This distance should satisfy concerns the SMSC had with the proximity and operation of the proposed pit. Ryan Contracting is proposing to use satellite toilet facilities on the site. A maximum of five employees will be working on the site, not including independent trucking COIl)panies. The satellite toilet facilities wi!! b~ maintained by an independent company and maintained weekly during the operating months of the year. This facility will be located adjacent to our parking area as shown in Exhibit. 8. This facility will be removed When our operation is not in use. 8 t --.i---"-'_C_" Fuel Storof!e: Ryan Contracting will be storing fuel on the site in an above ground 1000 gallon steel tank placed in a concrete enclosure. The fuel will be diesel fuel for the operating of the screening plant and the constniction equipment only. The concrete enclosure will contain spills if leakage from the tank did occur. The enclosure is made by Crest and is a MPCA approved design for this exact situation. Please see Exhibit 24 containing specifications on the enclosure. The enclosure will have a roof over it along with a metal chain link fence. The fuel tank will be locked when not in use. -.' -." Due to the concerns from the Shakopee Mdewakanton Sioux Community (SMSC) regarding fuel spillage, this is the best solution. The enclosure will trap . any fuel that is spilled or leaked out of the tank and will prevent fuel from contaminating the gromdwater. With the tank on site, this will reduce the number of refueling trips to the site and decreasing the possibility of a fuel spill.. In the unlikely event a fuel spill would occur, Ryan Contracting would respond by following state guidelines as outlined by the MPCA.' These guidelines are included in our application under Exhibit 24. Equipment Fuel: The SMSC has expressed concerns regarding possible fuel spills from the intregal fuel tanks on out equipment These concerns are unwarranted. The intregal tanks constructed on heavy equipment are built for heavy operations to withstand hard and severe use. The possibility of a fuel spill caused by a ruptured fuel tank from our equipment is far less likely than a fuel spill from your own car. Ryan Contracting Company will not be drilling or installing any wells on this property. Ryan Contracting Company will be taking water from the sedimentation pond for use on site to water roads. 9 WATER TESTING OF WETLAND 70-247W Ryan contracting will conduct annual water testing ofthe Wetland 70-247W as described in the attached letter from Braun Intertec. : :~~ II NOV 19 '99 11:37AM ERAUN INTERTEC ELDG2 P.1/2 BRAUNSIA I NTERTEC Braun Intertec Cvrporotion 6875 Washington Avenue South Minncapoli:, Minne-..ola SS.439-01 08 612.941.5600 Fax; 9,42-4844 November 19, 1999- Engineers and Sci~nr.$r: S!rving rhs Bull, and No/lJrat Envlranment~ Mr. Craig Svoboda Ryan Contracting Co. 8700 13111 Avenue East Shakopee,~ 55379 Dear Craig: Re: Field Collection and Laboratory Analysis of Pit Water Samples Thank you for your request for a price quotation for our analytical laboratory services. .Braun Interte'-,= appreciates the opportunity to present this information for your review.

Crooks Vice Chairman Susan Totenhagen SecretaryfTreasurer .~- RE: Coimnents on Conditional Use Permit Application of Ryan Contracting Dear Ms. Kansier: The following are the comments of the Shakopee Mdewakanton Sioux Community (SMSC) on the conditional Use Permit (CUP) application submitted by Ryan Contracting for a gravel mining operation located in the South 1/3 of Section 22, Township 115 North, Range 22 WesL These comments address the following issues: 1) proximity ofthe gravel mining operation to an existing Public Water Supply (PWS) well head; 2) potential . contamination of the surface and surficial aquifers; 3) noise; 4) dust; 5) visual impacts; 6) erosion control; 7) traffic concerns; and 8) cultur.aluse conflicts. '. WELL HEAD Background. The SMSC has a PWS well located approximately 1/4 mile northwest of the proposed location. This well draws water from the Jordan Aquifer. It is cased through the overlying glacial material and grouted into the Prairie Du Chien Formation. It is open for the entire thickness of Jordan Formation. The well provides the sole drinking water supply for the entire north water service area ofthe'Shakopee Mdewakanton Sioux Community. The groundwater flow is from the southeast to the northwest. The mining operation is likely to fall within the drinking water protection area of the well head protection area for this well. The SMSC is deeply concerned that adequate measures are taken to protect the drinking water supply. The CUP application states that there will be no fuel storage on the site. Stationary machinery located on the site (screening plant) will, however, have fuel tanks as part of the installation. Another potential source of contamination includes fuel releases from trucks hauling on the site and "on site" refueling operations. Celebrating 30 Years as a Tribal Government I I , . '. Comments on Conditional Use permit Application of Ryan Contracting 2 Comments. . Locate all fixed machinery on the site on an impermeable surface with adequate measures to control spills that may occur during refueling and a catastrophic release from a fuel tame . Limit the number of trucks to five on the site at anyone time. . Requiring immediate clean up of any release. . Provide a contingency plan for response to any release of petroleum products, or any other material. (This contingency plan shall be reviewed and accepted by City staff prior to issuance of any CUP.) . Require an Environmental Assessment Worksheet be completed for this and other erimonmental concerns. SURFACE CONTAMINATION Background. These concerns are somewhat similar to those stated above. There is an additional risk of impact from any release reaching surface water bodies or contaminating soil downstream from the release site and the facility. Surface water draining this area flows across tribal lands and eventually reaches the Minnesota River via Deans Lake. Comtnents. . Locate machinery installations on an impermeable surface. . Restrict the number of trucks on site. . Place an oil skimmer and a trash skimmer on the ponding area outlet to prevent any release from traveling off site. . Provide a contingency plan for dealing with releases and make compliance mandatory. . Require a dedicated area for stockpiling soil contaminated in any release as part of the contingency plan. . The contaminated soil stockpile area should have an impermeable surface and access for rapid removal of material located there. . . Require the contingency plan to have stated term of remediation for any release and make remediation within this time frame a condition of continuing the use permit. . Require an Environmental Assessment Worksheet be completed for this and other environmental concerns. Comments on Conditional Use permit Application of Ryan Contracting 3 NOISE Background. This is an almost unavoidable issue with a screening plant. The plans submitted call for berming and a vegetative barrier. These will mitigate the noise to some extent if the berm and barrier are high enough and thickly vegetated. There will be unavoidable noise impacts related to operation of the plant. The hour:~ of operation conflict with the nearby residential uses. Comments. . Berm and vegetative barrier design should be reviewed and strengthened to effectively minimize the noise pollution. The current plan does not adequately address this issue. . Hours of operation should be shortened to reduce noise impacts on residential use areas. . RetJ.uire an Environmental Assessment Worksheet be completed for this and other environmental concerns. DUST Background. Dust will be generated during stripping, mining, screening and hauling. This dust will be difficult to contain on site. The application calls for watering of haul roads for dust control. This will address one third of the potential dust generating operations. Comments. . Require roads to be regularly coated with a dust control solution in addition to water. . Locate all machinery such that it minimizes off site migration of dust. . Immediately stockpile and cover or re-vegetate stripped soil to prevent wind erosion. . Require an Environmental Assessment Worksheet be completed for this and other environmental concerns. VISUAL IMPACTS Background. The site is visible from McKenna Road and the residences located along that road. Removal of trees and mining will create a highly visible industrial operation in an area that is currently primarily agricultural or forested. Comments. . Retain the maximum number of large trees. . Re-vegetate with trees as soon as possible and before mining on the west end of the project to enhance the visual barriers provided by berms and the pit walls. . Plant sufficient trees and shrubs to create and effective visual barrier. (Maximum spacing of trees 10 feet.) I I --r----.---.---------.-. Comments on Conditional Use permit Application of Ryan Contracting 4 . Require an Environmental Assessment Worksheet be completed for this and other environmental concerns. EROSION CONTROL Background. Erosion and off site transport of soil is a serious issue. The stripped topsoil and exposed mining faces will be extremely susceptible to erosion. The eroded soil will be transported downstream and could seriously impact all receiving water bodies. Comments. . Immediately stockpile and cover or re-vegetate stripped soil to prevent water erosion. . Re-vegetate all mined areas as soon as possible to prevent soil erosion with stated tinfetables for such planting or seeding and limits on the time soil may remain exposed. . Topsoil stockpiles on site should be protected with silt fence until any seed germinates and anchors the soil. . Provide a planned time table for dredging on site ponds. . Require an Environmental Assessment Worksheet be completed for this and other environmental concerns. TRAFFIC CONCERNS Background. The total amount of material planned for removal is 500,000 cubic yards. Given the planned use as indicated by Ryan Construction to the SMSC staff, this will result in 200,000 cubic yards extracted in the fIrst year of operation. The mine is expected to operate with a minimum of 5,000 cubic yards being hauled each day. Assuming 20 yard trucks, this will result in 500 total trips per day and a signifIcant change in the existing traffIc type. The application proposes all traffic being directed south on McKenna Road to County 42. The intersection of County 42 and McKenna Road is not signaled. The operation is likely to result in signifIcant traffic delays for person residing north of the site on McKenna Road attempting to reach County 42. There is no detail on the ultimate use planned for the area.' This ultimate use will have signifIcant impacts on the areas. Comments. . Require specifIc actions by the permitee to ensure that traffic does actually use the preferred routes. . Provide roadway signage in accordance to the Minnesota Manual on Uniform TraffIc Control Devices. . Penalties for truck operators or the permitee if the operators do not use the established routes. . , . Comments on Conditional Use permit Application of Ryan Contracting 5 . Examine all sight lines and traffic controls in light of the changed character of the traffic. . Require detail information on the ultimate use plan for the land. . Require a performance bond for Mckenna road damage. . The haul road is located in the middle of a sharp curve just north of CSAH 42. Sight distance between this driveway and the west on Mckenna Road is very restricted by a vertical curve on McKenna Road. Thus serious safety conflicts are likely to arise between the southbound/eastbound motorists on McKenna Road and trucks exiting from the driveway due to the insufficient sight distance of the haul access driveway. CULTURAL CONCERNS Background. The larict immediately to the north of the proposed facility is a forested area owned by the Shakopee Mdewakanton Sioux community. This land is planned to remain forested for the next 30 to 40 years. The area is used by tribal members for cultural purposes. The presence of a mining operation is in direct conflict with spiritual activities, plant gathering and other cultural activities. If this situation is considered in a mainstream European derived cultural framework the project would be analogous to siting the mining across the street from a church and next to a public park and recreational facility. Comments. . Do not issue the permit. Failing that: . Restrict hours of operation and eliminate weekend operation. . Require a significant buffer strip between the wooded areas and the actual mining operation. . Require fencing and a physical sound barrier between the forested area and the mining operation. . Require an Environmental Assessment Worksheet be completed for this and other environmental concerns. Sincerely, Stanley R.

Crowchild Ssr;rstsryrrrl1s$urer February 7, 2000 Frank Boyles, Manager City of Prior Lake 13200 Eagle Creek Avenue SE Prior Lake, MN 55372 Dear Mr. Boyles: On behalf of the Shakopee Mdewakanton. Sioux (Dakota) Community (SMSC), I am writing this letter with regard to the Prior Lake City Council's consideration of the Ryan Contracting application for a CUP to conduct gravel mining on land adjacent to the SMSC. I hereby reiterate the SMSC's strong opposition to the granting of the CUP. We believe we have provided the City of Prior Lake with sufficient information for the City Council to deny the CUP outright. We also believe that such a decision is easily defensible. However, in the event the City Council grants Ryan Contacting, Inc. a conditional use permit to mine gravel the Shakopee Mdewakanton Sioux Community requests the following conditions be placed on the permit, in addition to those recommended by the City staff. Hours of Operation. The hours of operation shall begin no earlier than 8 :00 a.m. and end no later than 6:00 p.m. Recvcling of Material. No recycling of any material shall be allowed at the site regardless of the source or type of material. Reporting. The SMSC shall be copied on all environmental reports submitted to the City of Prior Lake and on all communications from the City to Ryan regarding environmental aspects of the mining operation. This shall include any notice of requited dust control watering. All reports shall include the full analytical report from any laboratory and all additional information generated or reported by Ryan or its employees or contractors. I I 1---.---------- .Fe b. '1. 2000 3: 37PM No. 2702 P. 3/3 Frank Boyles, Manage, Februal')J 7,2000 Page 2 Monitorin2 Methods. All laboratory analyses shall be performed by a laboratory certified by the United States Environmental Protection Agency and shall include a full chain of custody for sampling, tranSportation and intemallaboratory operations. All site monitoring shall be in accordance with a monitoring plan approved by the City of Prior Lake. That plan shall Clearly state sample collection protocols, the sampling periods, analytical methods and limits and shall detine quality assurance steps. Again, the SMSC does not support granting the conditional use permit. Adding the above stated conditions to those already proposed will partially address the Community's concerns. This will not eliminate potential adverse impacts on the enjoyment and use of the SMSC's property and potential risks to the environment but it may help recognize impacts and will focus the attention of the pennitee on the potential risks.
