MPCA Accelerated Implementation of MS4 Permit Requirements Activities

Staffing and support for the Accelerated Implementation of municipal stormwater (MS4) Permit Requirements program. The purpose of this program is accelerating municipal stormwater (MS4) implementation activities by providing technical assistance and guidance development to permittees. To date the program has establishment of a digital document library (DDL) which is housed in the MN Stormwater Manual. The DDL is a culmination of permittee-developed documents vetted and endorsed by the Minnesota Pollution Control Agency (MPCA), which permittees can use and share to comply with the MS4 permit. The program has also began initial steps to update and enhance the “MS4 Toolkit”, which is a package of best practices that will facilitate establishing effective stormwater programs at the local level. Such practices are related to public education and outreach, public participation, illicit discharge detection and elimination, construction site stormwater runoff control, post-construction stormwater runoff management and MS4-owned infrastructure management. The MPCA has also initiated development of model ordinances, which can be used by regulated MS4s as the backbone of an effective local stormwater program.
