HomeMy WebLinkAbout4 - McKenna Sand & Gravel Mine Operation AGENDA NUMBER: PREPARED BY: SUBJECT: DATE: INTRODUCTION: BACKGROUND: "CELEBRATE PRIOR LAKE'S CENTENNIAL - 1991" 4 HORST W. GRASER CONSIDER APPROVAL OF RESOLUTION 91-32 ON METROPOLITAN SIGNIFICANCE REVIEW FOR PROPOSED MCKENNA SAND AND GRAVEL MINE OPERATION JULY 15, 1991 Staff has prepared Resolution 91-32 at the request of the Mdewakanton sioux Community to petition the Metropolitan Council for a Metropolitan Significance Review (MSR) of the proposed McKenna Sand and Gravel Mine adjacent to McKenna Road in the City of Shakopee. Enclosed is a copy of a letter from Leonard Prescott to Mayor Andren with this request. The Cit~ Council is requested to adopt a resolut1on which together with a Resolution drafted by the Mdewakanton Sioux Community would be forwarded to the Metropolitan Council for consideration. The proposed McKenna Sand and Gravel mining operation has been in the review stage for about five (5) months. Durin9 this time the Shakopee Planning Commiss1on granted a conditional s~ecial use ~ermit with one of the conditions be1ng an Env1ronmental Assessment Worksheet (EAW). Staff responded to the EAW notice with comments contained in a letter dated May 23, 1991, from Horst Graser to Lindberg Ekola, Shakopee City Planner, (attached). The Mdewakanton sioux Community also responded with comments which raised land use, traffic, environmental, and quality of life issues of the residents of the adjacent reservation (attached). These two responses form the basis for the Metropolitan Significance Review request. The purpose of the MSR is to assure that the total effect of a proposed project alleged to be of metropolitan significance is considered and the orderly and economic development of the area is promoted. Minnesota rules Chapter 5800.0010 outlines the MSR process. The MSR process contains criteria which qualify a project for MSR. This review is filed under Subpart 4, Paragraph A, which reads as follows: 4629 Dakota St. S.E., Prior Lake, Minnesota 55372 / Ph. (612) 447-4230 / Fax (612) 447-4245 An Equal Opportunity/Affirmative Action Employer DISCUSSION: A. May have a substantial physical effect on a local 90vernment unit other than the local un1t in which the proposed project is located. More specifically, a proposed project may be of metropolitan si~nificance if it adversely affects eX1sting or proposed land use or development in another local government with respect to traffic, storm water runoff, groundwater pollution, air or noise pOllution, increased security needs (police, fire) or other similar impacts. Also the content of the resolution must contain an arguable claim of metropolitan significance. All claims must be defensible by the local unit of government. There will be a scoping session by the Metropolitan Council to determine which issues raised are legitimate for review. Only approved issues will be allowed at a future Metropolitan Council Public Hearing. The Metropolitan Council plays the role of a moderator in this process with the worst case being a one year suspension of the project. However, these reviews usually result in some plan modification that is acceptable to all parties. It is the opinion of Staff that the sioux Community will not oppose the project if plan modification and access changes are made. Prior Lake and the sioux Community need to coordinate the presentation to the MSR Committee. The issues are interelated since the sioux are residents of Prior Lake but chose to represent themselves in a land use issue outside the reservation. To com~licate matters, the Mdewakanton Sioux Commun1ty is not a reco9nized government eligible for MSR which requ1res Prior Lake to initiate the review. Staff envisions this MSR to be a joint presentation by Prior Lake and its sponsor the Mdewakanton sioux Community, rather that Prior Lake submitting in behalf of the Mdewakanton Sioux Community. In effect, we will defend the statements in our Resolution and they will be responsible for defending statements in their Resolution. It is probable that the McKenna Sand and Gravel operation will expand into Prior Lake if successful in Shakopee. The review process with realigned governments could repeat itself in short order. ALTERNATIVES: RECOMMENDATION: ACTION REQUIRED: 1. 2. 3. Approve Resolution 91-32 Deny Resolution 91-32 Continue the item for information. additional Alternative #1 Motion to approve Resolution 91-32 may be in order. RESOLUTION 91-32 RESOLUTION REQUESTING METROPOLITAN SIGNIFICANCE REVIEW BY THE METROPOLITAN COUNCIL IN ACCORDANCE WITH MINNESOTA STATUTE 473.173, AND MINNESOTA RULES CHAPTER 5800.0060 SUBPART 1, SECTION B, OF THE MCKENNA SAND AND GRAVEL MINE WITHIN THE CITY OF SHAKOPEE MOTION BY SECONDED BY WHEREAS, the City Council of Prior Lake was given notice on June 14, 1991, of a proposed sand and gravel m1n1ng operation by McKenna Sand and Gravel Company consisting of forty (40) acres located adjacent to and directly north and east of McKenna Road and the City boundary of Prior Lake; and WHEREAS, the City Council of Prior Lake has determined that in accordance with Minnesota Rules Chapter 5800.0040 Subpart 3, section A, the sand and gravel mining operation may have detrimental effects on the City of Prior Lake and the Shakopee Mdewakanton sioux community also in the City of Prior Lake and located directly adjacent to and west of the proposed operation as follows: (a) (b) Land Use the mining operation will produce substantial dust, noise, and visual pollution that will compromise the quality of life currently experienced by the Mdewakanton sioux Community, negatively affect the character of the surrounding residential and farming community, and 9reatly reduce land use options for vacant land 1n the area. Traffic - the EAW has not adequately addressed the affect the volume of traffic will have on area land use, the problems resulting from assimilating mine traffic with the ~redominately passenger traffic of County Road 42, 1nternal mine traffic, regional mine access, hours of operation, and noise generated by accelerating trucks. Furthermore, the EAW inadequately addresses truck and equipment generated pollution such as dust and vehicle related air contaminants and fails to provide prudent design and access alternatives. (c) storm Water Management - there is a general lack of specificity in the amount and management of storm water. (d) Reclamation Plan - the reclamation plan provides no assurance that the work will be done in a timely manner. NOW THEREFORE BE IT RESOLVED BY THE MAYOR AND CITY COUNCIL OF PRIOR LAKE, that this Resolution be forwarded to the Metropolitan council for review and consideration.

Prior Lake, MN 55372 Re:Proposed McKenna Gravel Mining Operation Dear Mayor Andren: As we recently discussed, the Shakopee Planning Commission has before it an application by David McKenna for a conditional use permit and mining permit to operate a gravel mine on an 80-acre site in Shakopee on the east side of McKenna Road and north of County Road 42. The Shakopee Mdewakanton Sioux Community has Reservation land which lies on the west side of McKenna Road, across from the proposed gravel mining operation, and a number of the members of our community have homes on this Reservation land. The Community is opposed to the gravel operation because of the anticipated gravel truck traffic, noise, dust and other problems. We are requesting the City of Shakopee to consider an ordinance amendment to prohibi t such gravel mining operations in residential districts. We also are requesting that the McKenna project be referred to the Metropolitan Council for review. A copy of my letter to the Shakopee Mayor and Council in this regard is enclosed for your reference. We hope you will support in these requests to the City of Shakopee. We feel that this level of gravel truck traffic through portions of Prior Lake will have a serious impact not only upon the Reservation land, but upon Prior Lake and its residents. We would like you to consider taking two steps with regard to this proposed gravel mine: Honorable Lydia Andren City of Prior Lake May 23, 1991 page 2 (1) write a letter to the Shakopee Mayor and Council making the same requests set forth in my letter to them. (2) Adopt a Council resolution under Minnesota Rules, section 5800.0060, Subpart 1B requesting the Metropolitan Council to conduct a metropolitan significance review. It is important that the request to the Metropolitan Council be made as soon as possible, since the project would be exempt from Metropolitan Council review once 30 days have elapsed after a negative declaration on the environmental assessment worksheet. In addition to the requests to the Metropolitan Council and the City of Shakopee, we would like to talk with you further about responding to the EAW for this project. We feel that comments on the EAW should be made by the city of Prior Lake, and we would be happy to coordinate those comments with the comments made by our attorneys and engineers.

Ekola city Planner Shakopee City Hall 129 1st Avenue East Shakopee, MN 55379 RE: McKenna Sand and Gravel Mine, EAW comments. Dear Mr. Ekola, The city of Prior Lake has received the above referenced EAW and has the following comments: LAND USE: Prior Lake's Comprehensive Plan was adopted in 1981 and the Zonin9 Code implementing the plan in 1983. The areas adjacent to the m1ne are designated as agricultural in the plan and zoned A-1 agricultural in the Zoning Ordinance. It is anticipated that this will remain agricultural in the current comprehensive plan update. Consequently Prior Lake's 2010 urban service area will remain south of Co. Rd. 42. It would appear that the mining operation will be concluded by the time Prior Lake considers the land between Co. Rd. 42 and the mining operation for the inclusion in urban services area. In the event the mine is still in operation at such a time, Prior Lake will seek mitigating measures to offset the negative impacts of noise, truck traffic, fumes, dust and pollution of the urban environment in areas adjacent to the mining operation. Prior Lake does not want urban land use patterns and investment in infrastructure to reflect the negative aspects of a gravel mining operation. Located adjacent to the west of the mining operation is the 160 acre Mdewakanton sioux Indian community consisting of 35 residential units. Eleven of the units are directly impacted by the everyday operation of the mine because of the proximity to the operation. Mitigating measures must be in place prior to the start up of the mining operation. LAND USE MITIGATING MEASURES: 1.) When the two quarter/quarter sections lying directly to south of the mining operation are included in the Prior urban service area, then all truck traffic related to operation must cease from using all sections of McKenna maintained and controlled by Prior Lake. In the event the Lake the Road this 4629 Dakota St. SE. Prior Lake. Minnesota 55372 / Ph. (612) 447-4230 / Fax (612) 447-424~ An Equal Opportunity/Affirmative Action Employer occurs, all temporary access permits will be revoked. 2.) The planting plan on the berm facing the city limits of Prior Lake must be designed by a registered landscape architect and specifications on plant material must be included in the plan. The plant material must make an immediate impact with the following minimums: a. ) b. ) c. ) Evergreens - 6' minimum Deciduous - 2.5" caliper measured Watering as required for first planting. 12" above base two years after 3.) To reduce the influence of noise and to provide some relief from ubiquitous mining sounds emanating from the mine, the hours of operation must be confined to the hours between 7:30 a.m. and 6:00 p.m. The operation shall be closed on all weekends and holidays. TRAFFIC: Item 22 in the EAW suggests that peak ADT from the operation can result in 200 trips, which is one truck trip ever~ 90 seconds between 7:30 a.m. and 6:00 p.m. Normal activity 1S anticipated to generate one truck trip every 11 minutes for the same period. The ADT is dependent on the construction activities in the region and length of the haul. Peak periods ma~ last from as little as a few hours to several weeks. All traff1c volume is scheduled to access the operation from Co. Rd. 42 via McKenna Road to the mine access road. Prior Lake will not agree to take all the traffic from the operation. The operation must be accessible from the north utilizing McKenna Road and the northerly mine access. The proposed volume of traffic from the mine as compared to Co. Rd. 42 is relatively low. The current traffic on Co. Rd. 42 is predominately passenger vehicles. The slow moving and accelerating trucks will add an undesirable component to the ever increasing volume of traffic on Co. Rd. 42. The truck traffic from the mine to Co. Rd. 42 is the most visual daily reminder of the operation. The traffic transforms a tranquil low density rural environment to one out of human scale. Mitigating measures must include all elements and conditions which will comprise the residential character of the Mdewakanton Community and the agricultural district. TRAFFIC MITIGATING MEASURES: 1.) All truck traffic from the minin~ operation must be kept from using the section of McKenna Road lY1ng between two access points as shown on the EAW maps. 2.) The mine access road from the mine south to McKenna Road, must be paved to prevent dust from deteriorating the residential environment of the Mdewakanton sioux Community. 3.) The applicant must pay for any improvements to Co. Rd. 42 as deemed appropriate by the City and County Engineers. 4.) Any sections of McKenna Road used by truck traffic from this operation must be upgraded to a standard considered safe and appropriate by the City Engineer of Prior Lake. 5.) A maintenance pro9ram for any sections of McKenna Road used by the mining operat1on must be in place prior to the operation and agreed to by the Prior Lake City Engineer. 6.) The applicant must submit to the Prior Lake City Engineer a detailed plan on how internal site traffic is organized. 7.) Truck traffic must be allowed to use that portion of McKenna Road north of the northerly access drive of the mine. 8.) All access points to McKenna Road in Prior Lake will re~ire a driveway permit from the Cit~ En9ineer. The City Counc11 of Prior Lake will consider the app11cat1ons. 9.) Any grading in the City limits of Prior Lake will require a grading permit from the city Engineer. LAND REHABILITATION: If the mining operation is successful in securing all necessary permits and mineral is extracted over a period of time, the City of Shakopee should have in place guarantees for eventual rehabilitation of the mine. It is suggested that the City Council of Shakopee require a bond from the fee owner of the land in an amount sufficient to provide for the reclamation of the mine in the event the applicant does not. In the event you have any questions regarding these points, I would be happy to discuss them in greater detail. Sif0. Horst W.

Treasurer May 29, 1991 City of Shakopee 129 First Avenue East Shakopee, Minnesota 55379 Attention: Mr. Lindberg S. Ekola Re: Environmental Assessment Worksheet for the Proposed McKenna Sand and Gravel Mine, Shakopee, Minnesota Dear Mr. Ekola: The Shakopee Mdewakanton Sioux Community ("SMSC") occupies a reservation, one hundred sixty acres of which are located immediately adjacent to the westerly boundary of the McKenna's project. This property (the "SMSC Reservation") currently contains approximately 42 dwellings which house 77 adults and 33 children. SMSC is extremely concerned about the effect this project will have on the environment and offers the following comments on the EAW. We trust that you will carefully consider these comments (and your responses thereto) when you make your decision as to the need for an EIS. INADEOUACY OF EA W: SIGNIFICANT ENVIRONMENT At EFFECTS The EAW is inadequate (as more specifically addressed below) because it fails to include information needed to determine the potential for, or significance of, certain environmental impacts. This project will potentially significantly affect several aspects of the environment. The Environmental Quality Board Rules define "environment" to include ambient noise, air, water, flora, fauna, land and man-made or natural features of historic, geologic, or aesthetic significance. 1. Impact on Ambient Noise Levels. Significant noise levels will be generated from several activities-operation of gravel mining equipment, gravel crushing, screening and processing equipment, conveyers used to stockpile gravel, gravel being loaded into trucks, trucks entering, leaving and maneuvering within the site and heavy gravel truck traffic on adjoining City of Shakopee Page 2 May 29,1991 public roads. Trucks on and off the site are of particular concern since their operation generates considerable noise-acceleration and gear shifting of heavy load trucks; back up warning beepers; etc. The effect of machinery noise upon nearby residents is exacerbated by the vibration that accompanies this noise. A. Inadequacy of maps. The maps accompanying the EAW in response to Question No.5 are inadequate to enable EAW reviewers to assess the distance between the above-described noise and vibration generating activities and the nearest homes on the SMSC Reservation. EA W Guidelines require that maps show "a graphic close up of the project in sufficient detail to identify key physical features" including roads, utilities, buildings, drainage structures, cut and fill areas, materials or waste storage areas. Of the above-described on-site noise and vibration generating activities, the maps show only the main access road location and the location of the crusher in phase I. The EAW is, therefore, inadequate to enable a reviewer to asses noise levels at the nearest receptor. The response to Question No. 25 says that the applicant will install on site circular truck routes to minimize truck back-up noise, but the maps do not show the number or location or give the reviewer any information to assess the extent to which these routes will mitigate the noise level at the receptor. A detailed plan for on site traffic for all phases of the project should have accompanied the EAW. We question the accuracy of the statement in the response to Question No.9 that "the distance from the aggregate processing area to the nearest residence. . . is approximately 1,000 feet." The measured distance on Map B from the phase I crusher location to the nearest depicted home appears to be 850 feet or 15% closer than the stated 1,000 feet. What is the location of "aggregate processing equipment" other than the crusher? Where will these activities be located in phases IT and m. Is the map accurate? At the March 7, 1991, Shakopee Planning Commission meeting regarding the conditional use permit required for the project, the applicant's engineer stated that the scale of certain of McKenna's maps was not accurate. Map B should be complete and accurate. City of Shakopee Page 3 May 29, 1991 B. General inadequacy of response to permit question: Compliance with noise standards. The response to Question No.8 is inadequate in that it states that the need for MPCA permits will be determined as a part of the EAW process. It is the responsibility of the RGU to provide the information called for in the EA W form. Failure to provide such information about the project deprives EAW reviewers of their right and opportunity to fully assess and comment upon the project during the 3D-day review period. The EAW does not cite any basis for the determination in the response to Question No. 25 that "typical mining equipment generates 88 dBA measured at 50 feet from the source." The accuracy of this information is critical since it presumably will form a part of the basis for determination by the MPCA and the City of Shakopee of whether or not the project will meet applicable MPCA and City ordinance noise standards. As mentioned above, other information needed to adequately determine whether this project will meet applicable noise standards is missing-Leo MPCA and City noise standards are phrased in terms of maximum noise levels at the nearest receptor; information about the distance between each noise source during each phase and the corresponding nearest receptor is inadequate. Any MPCA comments to the EA W regarding noise standards might differ if the EAW fully and accurately set forth the information required by the EA W form. C Inadequacy of information on berm landscaping. The response to Question No.9 says that the landscaping on the berms will help shield noise. However, the EAW contains no specifications as to the spacing, density or height of the plantings, the soil medium of the berm or the post planting maintenance plans. The berm landscaping should be tall enough and dense enough to have an immediate and significant mitigating effect. It can be expected that many of the plantings will die if planted in clay soil. There should be a landscape design by a registered landscape architect and a requirement for financial guarantees to ensure the long term viability of the plantings. City of Shakopee Page 4 May 29, 1991 Furthermore, there should be a requirement that the berm and landscaping be installed prior to commencement of operations. D. Accuracy of trip generation figure; nature of trucks. The response to Question No. 22 states that the maximum average daily traffic will be 200 trucks in the peak construction season. This determination is based upon the applicant's proposal to mine 1,000,000 cubic yards of gravel in 10 years. The EA W contains no information on borings or other geological basis for the determination that this site will produce only 1,000,000 cubic yards. Has this determination been verified? The accuracy of this figure is critical because, if the site yields greater amounts, the traffic (and impacts created thereby) may be greater and/ or the life of the project may be longer. If the traffic is greater, the assumptions in the EA W regarding noise levels from trucks are inaccurate. There is no indication that the site will be restricted to single unit trucks. "Double bottoms" {trucks with trailers} are believed to generate more noise. E. Validity of assumption that all trucks will be routed south. The response to Question No.9 says that truck traffic impacts on the SMSC Reservation will be minimized because all trucks will be routed to County Road 42 via the south mining access road. SMSC questions the validity of this statement because it seems highly unlikely that the City of Prior Lake will agree to handle all of this project's truck traffic. The response to Question No. 22 says that the applicant expects that the trucks will have a southerly destination. Is the compass direction of the project's market predictable over the life of the project? F. Hours of operation. The EAW mentions no limitation on hours of operation. To minimize noise and other impacts on residents of the SMSC Reservation and other surrounding properties, hours of operation should be limited to 9 a.m. to 5 p.m., Monday through Friday, holidays excluded. G. Security Concerns. After operating hours, gravel pits often attract uninvited noise producing activities such as target practice, dirt bikes and teenage partying. An on duty security guard should be required to prevent vehicular and pedestrian access. City of Shakopee Page 5 May 29, 1991 H. Improper characterization of adjacent land use. The response to Question No.9 indicates that adjacent land use is low density residential and agricultural. Although the SMSC Reservation now contains 42 dwellings, SMSC's zoning plan for this area permits one dwelling per acre. Given recent renewed interest in the preservation of Indian culture, it is quite possible that the residential population will significantly expand over the life of the McKenna's project (the next 12 years). Houses in greater number may be located nearer to the project than indicated in the EAW. Even if it is determined that noise levels measured at the currently existing nearest receptors meet City and MPCA standards, will noise levels measured at these future home sites meet standards? Unlike the typical person seeking a house site, Mdewakanton Sioux Indians desiring to live on a Mdewakanton Sioux reservation cannot simply find a different place to live which is not adjacent to a gravel mining operation. II. Impact on Air. A. Dust. This project will generate large quantities of dust as a result of traffic on dry, unpaved roads, the loading and conveying of gravel and wind blowing dust off trucks, machinery, mined areas and stock piles. As is the case with noise impacts (discussed above), the assumptions in the EAW about the amount of dust created generally by the site's activity level and specifically by the site's truck traffic level may be inaccurate if the assumption about this site's gravel production potential of 1,000,000 cubic yards is inaccurate. Also, as is the case with noise impacts, the assumption that traffic impacts on air will be minimized by southerly truck routing is suspect. The inadequacy of the maps is again problematic because they do not show the site's internal traffic layout, the location of all phase I machinery or the location of any machinery or stock piles in phases IT and m. The EA W states that the maximum height of stock piles will be 25 feet. The adequacy of this height limitation should be discussed in terms of the location of the stock piles in each phase. The response to Question No. 9 says that the landscaping on the berms will help shield dust and pollution. As mentioned above, the EAW does not contain adequate information to address concerns about the timing of installation, the quality and the long term viability of the berm landscaping. The inadequacy of the response to question No.8 is again apparent as the EAW contains no analysis of whether this project will meet MPCA City of Shakopee Page 6 May 29, 1991 standards regarding fugitive particulate matter. The response to Question No. 27 merely states that the applicant will have to be aware and comply with state air quality regulations. B. Air contaminants (including dust) generated by stationary sources. Minnesota Rwes, Part 7001.1210 requires sand and gravel operations (except those producing less than 150,000 tons of product per year) to obtain a stationary source air emission facility permit. Such a permit would presumably regulate all air contaminants (including dust and exhaust fumes and odors) emanating from the site's stationary sources including the crusher, the conveyers and the dust control chemicals. The EAW contains no discussion of this permit requirement and its applicability to this site, even though the Rules specifically refer to gravel operations. There is no discussion of the exhaust from the fuel used by the crusher or other equipment. The EA W indicates that only EP A and MPCA approved chemicals will be used for dust control. However, certain chemicals which are approved due to their limited potential to contaminate ground water have the unpleasant side effect of emitting odorous gases. C. Vehicle related air contaminants. The conclusion in the EAW that an indirect source permit is not required for this site may be different if the assumption about this site's gravel production potential of 1,000,000 cubic yards and the resulting trip generation figure are inaccurate. The EAW Guidelines (see comments to Question No. 23) indicate that, even if an indirect source permit is not required, a project may nevertheless require an estimate of likely air quality impacts if it contributes to traffic congestion. The unsubstantiated trip generation methodology in the EAW projects a maximum average traffic count of 200 trucks per day, but there is no discussion of how many trucks may be present at peak traffic times.on any given day. Has there been an analysis of the combined effect of the project's truck traffic and traffic from the race track, from Valley Fair and/or the SMSC casino? There is no indication of the speeds at which the trucks will travel or of weight loadings or whether "double bottoms" (trucks with trailers) will be prohibited. Acceleration lanes for trucks to gain speed before joining traffic should be required. Truck lanes should also be required on hills. Otherwise, bulky, slow moving gravel trucks in heavy traffic will contribute to traffic congestion and impact air quality. Ci ty of Shakopee Page 7 May 29,1991 m. Impact on Water. A. Effect of project's water use on availability of water in SMSC wells. There are 8 drinking water wells located on the SMSC Reservation. Six of those wells are located in the northerly 80 acres which are across McKenna Road from the project. Three wells are located along the easterly boundary of the SMSC Reservation and are especially near to the project. The response to Question No. 13.b says that water will be used for dust control and aggregate washing. Appropriation of additional water for dewatering purposes is not mentioned. Presumably, the applicant concludes that dewatering the pit will not be required based upon the assumption that the water table is lower than the area where mining activity will occur. What is the basis for the stated depth of the water table? Is it a reasonable conclusion that dewatering will not be necessary? The EA W contains no information as to the amount of water the project will use for dust control and aggregate washing and no information as to the rate of pumping and the direction of sub-surface water flow. There is inadequate information as to the depth and location of wells on the SMSC Reservation. SMSC is very concerned that the project's water pumping will create a zone of influence that will significantly decrease water availability in its wells. The attachments to the EA W include only one well log in SMSC's name. SMSC needs assurance that the location and depth of all its wells have been considered and that this project will not affect its water supply. A quantitative analysis of this project's impact on ground water levels should be provided as a part of the environmental review process. Even if it is determined that the project's water appropriation will not affect existing SMSC wells, will it affect ground water wells serving future home sites? As mentioned above, unlike the typical person seeking a house site, Mdewakanton Sioux Indians desiring to live on a Mdewakanton Sioux reservation cannot simply find a different place to live with water availability not affected by a gravel mining operation. B. Effect on water quality. 1. Environmental hazards due to past land use. The well log for applicant's Well No.4 refers to an underground fuel oil tank located 3S feet north of Well No.4. It is not clear from the well City of Shakopee Page 8 May 29,1991 location map whether this tank is located in an area that will be mined. The well map shows more than one well on the applicant's property. Any unused wells must be sealed so that they do not remain as possible entrance points for ground water contamination. Has the property been examined for other environmental concerns due to past land use? Fuel storage tanks, household dumps and contamination associated with farm equipment maintenance and the storage, transferral and disposal of agro chemicals are common environmental concerns on property that has been in agricultural use. 2. Substances used, and wastes produced, by the project which may potentially contaminate soil and ground water. The EAW says that there will be no on site storage of fuel for machinery. However, there is no discussion of how the crusher and other machinery will be fueled. We guess that the crusher will use diesel fuel. If there is no separate fuel storage tank on site, either the crusher must include a large integral tank or there will be frequent site visits by fueling trucks with the potential for spillage during fueling. Will measures be taken to prevent fuel from contaminating soil and ground water? How will machinery be maintained and repaired? Will oils and other hazardous substances used in maintenance be stored on site? If so, will they be stored in an environmentally appropriate manner? Will explosives be used or stored on site? What chemicals will be used for dust control? How will they be stored? Where will the recycle pond be located in each phase? The response to Question No 19.a says that there has been no determination of the quantity of the waste water stream from aggregate washing. Is the maximum size of the recycle pond sufficient to handle this unestimated volume of waste aggregate washing water? The response to Question 19.b says that the silt from the recycle pond will be spread on site. What is the estimated volume and composition of the silt? Will the silt contain any contaminants? The reclamation plan should include either the sealing of the water well or an appropriate maintenance plan so that it does not become an access point for water contamination. Although the EAW says that the direction of surface water flow is northerly and easterly, there is no indication of the direction of ground water flow. SMSC is City of Shakopee Page 9 May 29,1991 particularly concerned about potential ground water contamination because of the applicant's engineer's comment at the March 7, 1991, Shakopee Planning Commission meeting that ground water flows from the project westerly to the SMSC Reservation. The gravel to be removed by this project now serves as a natural filter for the water that ends up in SMSC's wells. What is the effect of removing this natural filter? 3. Effect on quantity and quality of storm water runoff. The response to Question No. 10 indicates that the site's impervious surfaces will increase by 500% as a result of the project. Is the on site sedimentation pond adequate to control sedimentation, phosphorus and additional run off? What contaminants may be present in the site's storm water discharge? Has the impact on Dean Lake, Pike Lake and the Minnesota River been adequately analyzed? When it issued new storm water regulations last November, the United States Environmental Protection Agency considered potential contamination of storm water run off from gravel pits significant enough to expressly include this industry by SIC Code (#1442) in the group of industries required to obtain NPDES permits for storm water discharges. There is no discussion of the anticipated impact of these regulations on the project. IV. Impact on Flora and Fauna. A. Effect on wildlife habitat. EAW Guidelines say that Questions 10 and 11 are included in the EAW form to insure an assessment of wildlife habitat. SMSC is very concerned about this project's impact on wildlife habitat because it will affect the wildlife on the SMSC Reservation. Residents of the SMSC Reservation now enjoy the presence of wood ducks, deer, birds, rabbits and squirrels. Residents also trap small game and hunt rabbits, squirrels, pheasant and other upland game on the SMSC Reservation. The response to Question No. 10 shows that, even after reclamation, the project will cause a 69% decrease in wooded/forest areas and a 100% decrease in brush/grassland. Obviously, no wildlife habitat will exist during mining operations. Even if there is phased reclamation, the noise and dust from the remaining phases will have an adverse effect on wildlife. Whathfmandal guarantees will be required to insure that the reclamation City of Shakopee Page 10 May 29,1991 plan will be implemented? Has the reclamation plan been analyzed from the standpoint of pre-project/post-project wildlife habitat? The EAW states that the project will last from eight to twelve years. It may last longer if the assumption about this site's gravel production potential of 1,000,000 cubic yards is inaccurate. Will the current level of wildlife return after this site is reclaimed or will its destruction be an irreversible environmental effect of this project? The response to Question No. l1.a says that the vegetation on the berm will provide some habitat. As mentioned above, however, the EAW does not contain adequate information to address concerns about the timing of installation, the quality and the long term viability of the berm landscaping. We question the accuracy of the statement that the site includes no wetlands. At the March 7, 1991, Shakopee Planning Commission meeting regarding the conditional use permit for this project, the applicant's engineer stated that an intermittent stream runs through the property. The stream is not shown on the maps included in the EAW. How significant is the stream to wildlife? It is apparent from the EAW that the RGU has not adequately addressed the quality and value of the project site's wildlife habitat. B. Effect upon flora on SMSC Reservation. Residents on the SMSC Reservation engage in the traditional Indian practices of gathering wild mushrooms, ginseng, berries, plums, choke cherries, wild grapes, herbs for medicinal and craft purposes and cutting small trees for building "sweat lodges" for spiritual sweat lodge ceremonies. SMSC is concerned that the dust and fumes generated by the project will adversely affect these natural resources on the SMSC Reservation. v. Impact on Land. A. Potential for soil contamination. For the same reasons as those set forth in Section ill. B above in the discussion of potential adverse impacts on water, SMSC is concerned about the potential for soil contamination. B. Adequacy of erosion control. The site contains steep slopes and erodible soils. Are the erosion and sedimentation measures to be employed during the project adequate? The response to Question No. 17 indicates that the acreage to be excavated is 40 acres. However, the grade break between existing and proposed contour lines on Map B Ci ty of Shakopee Page 11 May 29, 1991 show as much as 30 feet between existing and proposed elevations. This seems to indicate that the area to be excavated extends into the dty limits of Prior Lake. C. Reclamation plan. EA W Guidelines indicate that the project description called for by Question No.6 should focus on aspects of the project that may directly or indirectly manipulate, alter or impact the physical environment, including project closure actions. The reclamation plan that is attached is very general. Are post project erosion and sedimentation measures adequate? Will the reclaimed site support wildlife to its current extent? The reclamation plan should include either the sealing of the water well or an appropriate maintenance plan so that it does not become an access point for water contamination. \Vhat guarantees will be required to insure that reclamation will be timely and adequately accomplished and maintained? Financial guarantees should be posted by the fee owner of the land. D. Future expansion of proiect; Future use of site. Even though the applicant does not presently intend to mine more than 40 acres, SMSC is concerned that this intention may change and the project will be expanded in the future. Even though the response to Question No. 30 says that the applicant's brother will not obtain any rights to expand his operation as a result of this project, SMSC is also concerned that such operation will also want to expand. Owners of former gravel pits are often approached with proposals for siting cement plants, asphalt plants, recycling plants, etc. on old gravel pit lands. Even though any such expansions or new noxious uses would also require environmental review, once the City has permitted gravel mining to the extent of the currently proposed project, the environmental resources to be jeopardized by new projects will be far fewer than they are today. SMSC is concerned that this project will affect land use patterns and be the beginning of the continuing deterioration of the area's environment. VI. Impact on Man-made or Natural Features of Historic, Geologic, or Aesthetic Significance. A. Topography. As indicated in the response to Question No.6, the site contains many steep hills and variations in elevations. This City of Shakopee Page 12 May 29,1991 interesting topography is uncommon in the metropolitan area, is characteristic of areas near the river and is aesthetically pleasing. The hills can be seen in the distance from the surrounding properties. This aspect of the site will be totally and irreversibly destroyed by this project, leaving a site with a maximum grade of 18%. B. General character of site and surrounding area. Question No.9 calls for a discussion of any conflicts with nearby land use that involve environmental matters. EA W Guidelines (page 24) note that gravel mining is a nuisance to nearby residents and state that a complete discussion of surrounding land use should be given in the EA W. However, the EA W does not evidence a full appreciation of the current character of this area, which is a feature of aesthetic significance in and of itself. Residents of the SMSC Reservation now enjoy a tranquil agrarian/rural environment with birds, wildlife, woodlands, rolling hills and pleasing views. This project will convert that environment to one of noise, dust, fumes, truck traffic, heavy equipment, temporary shacks, gravel stock piles, stagnant sedimentation ponds and a denuded flat landscape. C. SMSC Reservation. The SMSC Reservation itself is a feature of historic and cultural significance. The land was dedicated by the United States Government to the Mdewakanton Sioux Tribe in 1889. This reservation is one of only four Sioux Indian reservations in the State of Minnesota. One hundred ten Sioux Indians currently make their home on this land. Activities are carried on in an attempt to preserve the culture of the Sioux Indian tribe, which once occupied all of the Minnesota River Valley. Many traditional Sioux Indian practices involve use of natural resources and the outdoor environment. As mentioned above, the land is used by residents for hunting, trapping, gathering and spiritual ceremonies. The EA W does not adequately address this project's effect upon such significant cultural and historical features of the neighboring lands even though the United States Supreme Court has given special recognition to the importance of protecting such features when they appertain to a federally recognized Indian tribe. City of Shakopee Page 13 May 29, 1991 OTHER INADEQUACIES OF EA W In addition to the above-mentioned inadequacies, the response to Question No.8 fails to mention the need for Metropolitan Council review. Under Chapter 5800 of the Minnesota Rules, a project is considered to have metropolitan significance and require review by the Metropolitan Council if it has a substantial physical effect on a local governmental unit other than the local unit in which the project is to be located. There is certainly a substantial physical effect on the SMSC Reservation. Given that the project abuts on Prior Lake land, that the applicant proposes to route the project's truck traffic through Prior Lake and that the grade breaks between existing and proposed contour lines on ~ap B seem to indicate grading into the city limits of Prior Lake, there is also a substantial physical effect on Prior Lake. The response to Question No.8 mentions only a driveway permit and a grading permit (for the south mining access road) from the City of Prior Lake. As stated in the response to Question 30.a, if there were any grading or excavation in Prior Lake, a permit would be required from Prior Lake. As mentioned above, Map B seems to indicate grading in Prior Lake. The routing of traffic through Prior Lake may also require a permit from Prior Lake. The EAW fails to discuss reasonable alternatives which would avoid this project's potential significant environmental impacts. On two occasions, SMSC has requested the applicant to come to SMSC with a proposal acceptable to the applicant whereby this project would be abandoned. The applicant has not yet responded. CONCLUSION This project has a potential for significant environmental effects on ambient noise, air, water, flora, fauna, land and features of historic, geologic and aesthetic significance. The effects will be extensive; they will be present every day during the 8 to 12 year (or longer) project life; and, some will be irreversible, even after reclamation. If this project proceeds, other noxious projects can be anticipated, creating the potential for even greater cumulative effects. The EAW fails to discuss the comparative environmental impact of reasonable alternatives. Because the EA W lacks reasonably available information about certain potential environmental effects and fails to even mention others, it is not suffident as the basis for a reasoned decision about the potential for, or significance of, the environmental impacts of Ci ty of Shakopee Page 14 May 29, 1991 this project. An EIS must be required in order to adequately address the potential environmental effects of this project. Respectfully submitted, SHAKOPEE MDEW AKANTON SIOUX COMMUNITY By Allene Ross, Vice-Chair
