 IMPORTANT NEWS

2022 MS4 General Permit Now in Effect

The Maine Department of Environmental Protection's Municipal Separate Storm Sewer System ("MS4") General Permit went into effect on 7/1/22.  There are several new provisions that provide more protections to water resources.  Some of these provisions include:

  • Conduct analytical water quality monitoring for stormwater outfalls to determine if prohibited discharges are occurring.
  • Remove verified prohibited stormwater discharges within 60 days of discovery (or develop an expeditious mitigation plan if removal within 60 days is infeasible).
  • Establish an Erosion & Sediment Control Ordinance or other regulatory mechanism to minimize sediment discharge from construction projects by 7/1/23.
  • Establish a Low Impact Development Ordinance or other regulatory mechanism to provide more stormwater treatment for redevelopment and new development projects by 7/1/24.

For more information please review the City's Stormwater Management Plan and/or contact the Stormwater Program Coordinator.
