Southeastern Michigan Phase II
Stormwater Information Clearinghouse

Meeting the Federal Stormwater Regulations

Michigan communities have two permit options available to meet the federal Phase II requirements. A brief description of each permit option is provided below. Additionally, you can download a detailed fact sheet comparing the two permit options and timelines for meeting the permit requirements.

General Phase II Presentation:

This presentation was developed to provide local government officials with a general overview of stormwater and the Phase II program. The presentation is downloadable as a Microsoft PowerPoint file and can be individualized as needed.

PERMIT OPTION 1:

Jurisdictional Storm Water General Permit (Permit No. MIS040000)

The final jurisdictional permit was released on February 26, 2003. Download the Jurisdictional Permit Application and Jurisdictional Permit Language.

Under the jurisdictional permit, the community must develop a Storm Water Management Plan (SWMP) that includes the following components:
  1. Public Education Plan (PEP):
    To promote, publicize, and facilitate watershed education and to encourage the public to reduce the discharge of pollutants in storm water.
  2. Illicit Discharge Elimination Plan (IDEP):
    A plan that prohibits and effectively eliminates illicit discharges, including sanitary wastewater, to the permittee’s drainage system.
  3. Public Participation Plan:
    A process to involve the public throughout the development and implementation of the storm water management plan.
  4. Construction Site Runoff Control:
    A plan for complying with local and state soil erosion and sedimentation controls.
  5. Pollution Prevention/Good Housekeeping:
    A plan that promotes pollution prevention within the municipality through such actions as: inspect and maintain structural controls, storm water conveyances, and roadways; waste disposal; pesticide and fertilizer application; and employee training.
  6. Post Construction Storm Water Management:
    A plan that requires the development of a comprehensive storm water management plan and development of a storm water ordinance to address post construction storm water runoff from new development and redevelopment.

PERMIT OPTION 2:

Watershed-Based Storm Water General Permit (Permit No. MIG6100000)

This permit program is in place and currently available across the State. Although the Watershed-Based Storm Water Permit addresses the same basic requirements as the jurisdictional permit option described above, the watershed-based permit provides much greater flexibility in how these basic requirements are selected and implemented. The watershed-based General Storm Water Permit also requires cooperative interaction with other public bodies outside the permittee’s jurisdiction. This cooperative approach is designed to accomplish storm water quality improvements watershed-wide, and provides an added benefit of cost sharing for some storm water controls. The permit term is 5 years. Download the Watershed-Based Permit Application and Watershed-Based Permit Language.

Under the watershed-based permit, a community must develop:
  1. Public Education Plan (PEP):
    To promote, publicize, and facilitate watershed education and to encourage the public to reduce the discharge of pollutants in storm water. This plan can be developed in collaboration with subwatershed partners.
  2. Illicit Discharge Elimination Plan (IDEP):
    A plan that prohibits and effectively eliminates illicit discharges, including sanitary wastewater, to the permittee’s drainage system.
  3. Watershed Management Plan:
    A plan developed in conjunction with neighboring communities that identifies and implements actions needed to resolve water quality and water quantity concerns by fostering cooperation among the various public and private entities in the watershed. (One plan is submitted for the entire watershed.)The watershed plan also requires a public participation plan that demonstrates how the public will be involved in development of the watershed plan.The watershed plan is due approximately 2 years after receiving a certificate of coverage and contains. The plan assesses the current nature and status of the watershed ecosystem; identifies short and long-term goals for the watershed, the actions needed to meet those goals, and the benefits and costs associated with those actions; identifies actions to meet goals; and must include a method for evaluation of progress.
Other documents that may be helpful during development of the watershed plan include:

Water Quality Management Plan for Southeast Michigan (SEMCOG)

Sample Storm Water Pollution Prevention Initiative (SWPPI): An action plan and schedule for implementing solutions to storm water quality problems identified in the Watershed Management Plan. Communities need to address pollution prevention and good housekeeping practices, construction site runoff control and post-construction runoff control. (Note: Each community must develop its own SWPPI. However, ideas from other communities within the subwatershed can be shared between plans.)
