Develop a SWPPP following the requirements of the permit. All waters located within one mile (aerial radius measurement) of the construction site that have the potential to receive a discharge from the site must be identified on the site map component of the SWPPP. Be sure to include any additional requirements needed for discharges to special waters. | Develop a SWPPP following the requirements of the permit.

Owners/operators of construction activity must complete several steps before completing a permit application and beginning construction. These steps also help owners/operators determine their eligibility for coverage under the general permit.
If you have comments, feedback and/or questions, please see the list of construction stormwater program contacts.
Where will the construction occur and what will the project involve? Identifying the construction site boundaries is important to determining which environmental resources may be at risk of being impacted by the project. Identify opportunities to phase the project so that vegetation will remain in those areas that will not have construction activity at the start of the project. Construction phasing can minimize or eliminate negative environmental impacts from the project.
The latitude and longitude can be obtained with Bing Maps during the online application process, a GPS unit, using a USGS topographic map (provide scale), or by using any of a number of mobile phone applications.
Contact other state and federal agencies and local units of government to determine what permits are required in addition to the National Pollutant Discharge Elimination System (NPDES) and State Disposal System (SDS) permit issued by the Minnesota Pollution Control Agency (MPCA).
Contact the Minnesota Environmental Quality Board, the appropriate state agency or local unit of government to determine if the proposed project meets or exceeds the thresholds outlined in the state environmental review rules (MN. Rules Chapter 4410.) Development of an Environmental Assessment Worksheet (EAW) may be required for the project prior to the issuance of any permits and before construction activity can begin.
The general stormwater permit for construction activity contains many requirements that must be considered during the planning phase of a construction project. Decisions made during planning may make the difference between the project requiring a more onerous individual permit instead of the general permit. •Minnesota NPDES/SDS Construction Stormwater General Permit
The following list identifies protected resources in Minnesota.
Develop a SWPPP following the requirements of the permit. All waters located within one mile (aerial radius measurement) of the construction site that have the potential to receive a discharge from the site must be identified on the site map component of the SWPPP. Be sure to include any additional requirements needed for discharges to special waters.
Check waters list in Steps 5A-C and 6C to determine which special waters, impaired waters and calcareous fens have a potential to receive a discharge after considering water flow and modifications to the construction plans made for the purpose of preventing water resource impacts. Discharges of concern for calcareous fens are direct discharges or an indirect discharge to the fen from the construction site within one mile.
Keep the list of waters that will receive discharges from the construction site. This information is required on the permit application form.
If special waters will receive a discharge within one mile of the construction site (identified in Steps 5A and 8) and the requirements (located in Appendix A of the general permit) for these discharges will not be fulfilled.
You will need an individual NPDES/SDS Construction Stormwater Permit. Contact the front desk (651-296-6300 or 800-657-3864) and ask for the Stormwater Policy and Technical Assistance Unit Lead.
An impaired water for phosphorus, turbidity, dissolved oxygen, or biotic impairment: 1.will receive a discharge as a result of the construction project and a.has an approved TMDL with an Approved Waste Load Allocation or b.has no approved TMDL or has an approved TMDL but no Waste Load Allocation?
2.and the SWPPP does not include best management practices to comply with all the applicable requirements?
If yes - you must apply for an individual permit. Contact the front desk (651-296-6300 or 800-657-3864) and ask for the Stormwater Policy and Technical Assistance Unit Lead.

Step 10b. Projects that require a paper application
For projects that will disturb 50 acres or more and have a discharge point on the project that is within one mile of, and flows to, as special or impaired, or applicants that do not have internet access:
Call the MPCA at 651-757-2119 or 800-657-3804 or email csw.pca@state.mn.us to obtain a Submittal Number and obtain a copy of the permit application. If the Submittal Number is not included with the paper permit application, the application will be considered incomplete.
Submittal deadlines: •Projects requiring an individual NPDES/SDS Construction Stormwater Permit - 180 days before the construction start date. •Projects disturbing 50 acres or more and have a discharge point on the project that is within one mile of, and flows to, a special water or an impaired water - 30 days before the construction start date submit application and SWPPP. •All other projects - 7 days before the construction start date.
When is permit coverage granted and construction can begin? •Projects disturbing 50 acres or more and have a discharge point on the project that is within one mile of, and flows to, a special water or an impaired water - 30 days after the postmarked date of the completed application unless notified in writing that the SWPPP does not meet the general permit requirements. •Projects requiring an individual NPDES/SDS construction stormwater permit - After process including permit development, public input, and permit issuance has been completed. •All other projects - 7 days after submitting the complete online application or 7 days after the postmarked date of the completed application form.
