�ir�nesota INSTRUCTIONS FOR
Pollut�an THE APPLICATION FOR MINNESOTA'S NPDES/SDS GENERAL
Con#rol STORMWATER PERMIT FOR CONSTRUCTION ACTIVITY
Agency
Submission of an application is notice that the owner and general contractor identified on the
application intend to be authorized by an NPDES/SDS permit issued for Stormwater discharges
associated with a construction activity in the State of Minnesota.
1. Indicate if a Stormwater Pollution Prevention Plan (SWPPP) has been prepared and the appropriate
sections (a and b of this question) have been addressed by answering "Yes" or "No". A SWPPP is a plan for
Stormwater discharge that includes erosion prevention measures and sediment controls that, when
implemented, will decrease soil erosion on a parcel of land and decrease potlution in receiving waters. This
plan must be developed prior to submitting a permit application. A sample plan and development tools are
available from the U.S. Environmental Protection Agency Stormwater Pollution Prevention Plans for
Construction Activities and from the MPCA Stormwater Compliance Tool Kit for Small Construction
Operators
For section "b" indicate if an Environmental Review has been completed if required, by answering "Yes"
or "No" or "NA" (not applicable). Environmental review looks at how a proposed project could potentially
affect the environment and looks at ways to avoid or minimize impacts before the project is permitted and
built. Examples of categories that may need an environmental review include residentiat devetopment;
industrial, commercial, and institutional facilities; and also highway projects. For certain projects,
environmental review is mandatory. For more details see the Guide to Minnesota Environmental Review
Rules, Chapter 6.
2. Discharges to Special or Impaired Waters
a. Special waters have qualities that warrant extra protection. There are several categories of special
waters and the requirements are different for each. A list of these special water categories can be
found in Appendix A of the permit. The additional requirements apply only to those portions of a
project that drain to a discharge point on the project that is within 1 mile of and flows to the special
water. Refer to Appendix A of the permit for the list of special waters and what additional
requirements apply to each. The information is also available using the Special and Impaired Waters
Search Tool .
Impaired waters are bodies of water that do not meet the water quality standards set up for their
designated use as determined by the State. Projects discharging to impaired waters also have
additional requirements. The additional requirements apply only to those portions of a project that
drain to a discharge point on the project that is within 1 mile of and flows to the impaired water.
The specific requirements can be found in Appendix A of the permit. Impaired waters for the
purpose of this permit are limited to those identified as impaired pursuant to section 303(d) of the
Clean Water Act where the pollutant(s) or stressor(s) are phosphorus (nutrient eutrophication
biological indicators), turbidity, dissolved oxygen, or biotic impairment (fish bioassessment, aquatic
plant bioassessment and aquatic macroinvertebtrate bioassessment). Use the interactive Special and
Impaired Waters Search Tool to determine if your project is required to follow the additional
requirements. On the application, indicate if the SWPPP for the project incorporates the additionat
requirements, if applicable. Consult the web page General Information about Impaired Waters and
Current TMDL List of Impaired Waters for additional information including a list of impaired waters.
b. An approval letter from the Department of Natural Resources (DNR) is needed to discharge to
calcareous fens. If the DNR does not respond to the request for a letter of approval within 30
calendar days, you may apply for permit coverage and check the NA box. Document this process in
the SWPPP for the project.
wq-strm2-51 Page 6 of 9
Permit No: MN R100001
3. Additional Application Review
a. Indicate by answering "Yes" or "No" whether the project will include alternative methods for the
permanent stormwater management system. You have the option of proposing an alternative,
innovative, permanent stormwater management system. You must send in the permit application and
the additional required information (see Part III.C.5 of the Permit) at least 90 days prior to the start of
construction if you choose this approach. You must receive an approval letter from the MPCA for this
method before beginning construction.
b. Attach the plans for the alternative system.
c. If the project disturbs 50 acres or more and has a discharge point (including sheet flow) that is within
one mile of and flows to an impaired or special water listed in Appendix A, the application and SWPPP
need to be submitted to the MPCA a minimum of 30 days prior to the start of construction.
4. The application requires a$400 application fee. Indicate that the application fee has been enctosed by
answering "Yes". Please make checks payable to: Minnesota Pollution Control Agency and submit the check
with the completed application to: MPCA, Construction Stormwater Permit Program, 520 Lafayette Road North,
St. Paul, MN 55155-4194. Applications received without the required fee will be returned to the sender.
5. List the construction project's name. Be specific. Examples: "Driveway at 123 Main St, Hudson", "Highway 169
bridge replacement (#79605) at the Rum River".
6. Project �ocation
a. Provide an address (if available) and brief description of the construction activity's location (for
example, "North West Corner of the Intersection of 45 Street and Irving Avenue, Minneapolis, MN").
Use any type of description that accurately portrays the project location.
b-e. Provide the names of all cities, counties, zip codes, and townships the construction activity takes
place in (for example, a roadway may cross county, city, or township boundaries).
f. Give the latitude and longitude of the centroid of the site. If the centroid of the site is not within the
site, give the latitude and longitude of a point within the site that is closest to the centroid of the site.
Give these values in degrees and decimal of degrees (preferred) alternatively in degrees, minutes and
seconds. To obtain the decimals of a degree, divide the minutes by 60 and the seconds by 360 and add
this to the degrees.
g. State how the information was gathered, if by GPS, by using a USGS topographic map (give the scate),
or an online tool such as the Toxics Release Inventorv Facilitv Sitin$ Tool. To use this tool, type either
the zip code or the city/township and the state. Zoom in to obtain the latitude and longitude.
7. List, in acres, the amount of area that will be disturbed for this project. This is not the size of the property;
do not include areas of the project that will not be disturbed.
8. Add the map to the SWPPP. United States Geological Survey (USGS) 7.5-minute quad maps or equivalent maps
may be used. USGS 7.5-minute quad maps may be printed from the Special and Impaired Waters Search Tool or
ordered at the USGS store. The map does not need to be submitted with the application unless the project is
disturbing 50 acres or more. The map should include the project boundaries. The project boundaries can be
added to the map electronically using the search tool above.
9. Indicate the type of construction activity by checking the appropriate box. Check "Residential and Road
Construction" if the road is part of a common plan of development and is developed in association with
residential devetopment. If you check "Other", describe the project.
10. lndicate to the nearest quarter acre, the existing and resulting areas of impervious surfaces. Impervious
surface means a constructed hard surface that either prevents or retards the entry of water into the soil and
causes water to run off the surface in greater quantities and at an increased rate of flow than prior to
development. Examples include rooftops, sidewalks, patios, driveways, parking lots, storage areas, and
concrete, asphalt, or gravel roads. (a. )"Existing" area means the area'of impervious surface that is present
prior to the start of this construction project. (b.) "Post construction" means the entire area of impervious
surtace after construction is completed. Subtract (a. ) from (b. ) to determine the area of new impervious
surtace.
wq-strm2-51 Page 7 of 9
Permit No: MN R100001
11. For projects creating one or more acres of cumulative new impervious surfaces, check the appropriate box to
indicate which type(s) of permanent stormwater management practices will be used. The "Other" box is
timited to those situations (such as proximity to bedrock) that are described in Part III.0 of the permit. See the
permit for a further description. If the "Other' box is checked, describe which situation outlined in Part III. C.
fits the project and what other permanent treatment (such as grassed swates, smaller ponds and/or grit
chambers) will be used on the project.
12. BRIEF�Y describe which water body(s) will receive stormwater runoff from the construction site or from the
discharge from permanent Stormwater management systems by completing the table. To determine which
water body(s) will receive stormwater runoff discharges, make a brief survey of the project's surrounding area.
Include the waters identified on a USGS 7.5-minute quad or equivalent map. See Appendix A of this permit to
determine if a water body is a special water or visit the website Special Waters Document. Impaired waters for
the purpose of this permit are those identified as impaired for the following pollutant(s) or stressor(s)
phosphorus (nutrient eutrophication biological indicators), turbidity, dissolved oxygen, or biotic impairment
(fish bioassessment, aquatic plant bioassessment and aquatic macroinvertebrate bioassessment). The easiest
way to find special or impaired waters in addition to all waterbodies is to use the interactive map tool, 5 ecial
and Impaired Waters Search tool. Impaired waters are also listed here:
http: / /www.pca.state.mn. us/water/tmdl/index.html
13. List the start and estimated completion dates of the construction project.
14. Owner Information: Provide the information requested of the owner of the company, organization, or other
entity for which this construction project is being done. The Owner means the person or party possessing the
title of the land on which the construction activities will occur; or if the construction activity is for a lease,
easement, or mineral rights license holder, the party or individual identified as the lease, easement or mineral
rights license holder; or the contracting government agency responsible for the construction activity. The
owner is the party responsible for the compliance with all terms and conditions of the permit. The
alternate contact should be the owner's representative in charge of the project. ,
After completing this application, certify it with a signature and date from an individual authorized to sign the
application. This application form must be signed by either a principal executive officer, vice president,
representative agent responsible for overall operations, general partner, or a proprietor. If the activity is being
conducted by a unit of government (state, county, municipality, or township), this application must be signed
by a principal executive officer or ranking elected official (for example, city or county engineer, administrator,
or manager; director of public works; mayor, etc.) For additional information, see Minnesota Rules 7001.0060.
15. Contractor (Operator) Information: Provide the information requested of the contractor. The Contractor
means the party who signs the construction contract with the owner to construct the project described in the
final plans and specifications. Where the construction project involves more than one contractor, the general
contractor will be the party responsible for managing the project on behalf of the owner. In some cases the
owner may be the general contractor. In these cases, the owner may contract an individual as the operator
who would be the co-permittee. The operator (usually the general contractor) is jointly responsible with
the owner for compliance with Part II.B., Part II.C., and Part IV of the permit.
After this application has been completed by the owner, the contractor must certify it with a signature and
date from an individual authorized to sign the form. The application must be signed by either a principal
executive officer, vice president, representative agent responsible for overall operations, general partner, or a
proprietor. If the general contractor is a unit of government (state, county, municipality, or township), this
application must be signed by a principal executive officer, ranking elected official, administrator, manager,
coordinator, or engineer. (For additional information, see Minnesota Rules 7001.0060.) The alternate contad
should be the contractor's representative in charge of the project.

Selection of a Permanent Stormwater Mana ement S stem III.0
Will the project create a new cumulative impervious surface greater than or equal to one acre? ❑ Yes ■
No
If yes, a water quality volume of'/z inch of runoff from this area must be treated before leaving the site or
enterin surface waters 1 inch if dischar in to s ecial waters).
Describe which method will be used to treat runoff from the new impervious surfaces created by the project
(III.C):
• Wet sedimentation basin
• Infiltration/Filtration
• Regional ponds
• Combination of practices
Include all calculations and design information for the method selected. See Part III.0 of the permit for
specific requirements associated witli each method.
N/A
If it is not feasible to meet the treatment requirement for the water quality volume, describe why. This can
include proximity to bedrock or road projects where the lack of right of way precludes the installation of
any permanent stormwater management practices. Describe what other treatment, such as grasses swales,
smaller ponds, or grit chambers, will be implexnented to treat runoff prior to discharge to surface waters.
(III.C)
N/A
If proposing an alternative method to treat runoff from the new impervious surfaces, describe how this
alternative will achieve approximately 80% removal of total suspended solids on an annual average basis
(III.C.S). NOT'E: If proposing an alternative method, you must submit your SWPPP to MPCA at least 90
days prior to the starting date of the construcrion activity.

etc.) before work begins.
Silt Fence, Rock Construction Entrance, Inlet Protection and Aggregate Wrapped in
Filter Fabric
Describe temporary erosion protection or permanent cover used for exposed soil. All exposed soil areas
must be stabilized as soon as possible but in no case later than 14 days after the construction activity in that
portion of the site has temporarily or permanently (part N.B.2)
Install temporary erosion control measure (inlet protection, silt fence, and rock
construction entrances) prior to beginning any excavation or demolition
For drainage or diversion ditches, describe practices to stabilize the normal wetted perimeter within 200
lineal feet of the property edge or point of discharge to surface water. The remaining portions of the
temporary or permanent ditch or swale must be stabilized within 14 days after connecting to surface waters
and construction in that portion of the ditch has temporarily or permanently ceased.
The erosion control measures shown on the lan are the absolute minimum. The
Page5of10
Twin Oaks Middle School Pavement Removal SWPPP
contractor shall install temporary earth dikes, sediment traps or basins, additional siltation
fencing, and/or disk the soil parallel to the contours as deemed necessary to further
control erosion. All changes andlor additional measures shall be recorded in the SWPPP.
Seeding and sod shall be placed on all exposed areas at the completion of the project.
Describe other erosion prevention practices (list and describe).
Aggregate wrapped in filter fabric and rock construction entrances are all prevention
practices intended for this project.

Sedi�tent CoMrol Pcact�es tY.0
Describe sediment control practices used to minimize sediments from entering surface waters, including
curb and gutter systems and storm drain inlets. At a minimum, these sediment control pracrices must
include:
• Sediment controls for temporary or permanent drainage ditches and sediment basins that are
designed as part of a treatment system
• Installation of check dams or other grade control practice to ensure sheet flow and prevent rills
(for slope lengths greater than 75 feet with a grade of 3:1 or steeper).
• Sediment control practices on all down gradient perimeters prior to land disturbing activities.
• Storm drain inlet protection for all inlets.
• Silt fencing or other sediment control surrounding temporary soil stockpiles.
• Minimize vehicle tracking of sediments (e.g., stone pads, concrete or steel wash racks, or
equivalent systems).
• Street sweeping of tracked sediment.
• Temporary sedimentation basins (see Part III.B).
