The National Pollutant Discharge Elimination System (NPDES) regulations for municipal separate storm sewer systems are federal regulations administered nationwide by the Environmental Protection Agency. Phase I of the program was applicable to large municipal separate storm sewer systems. Under Phase II of this program, regulations are applicable to small municipal separate storm sewer systems (MS4s).
The goal of this program is to limit the amount of pollutants entering our streams and lakes through separate storm sewer systems. A separate storm sewer system is a stormwater collection and conveyance system (inlets, piping, swales, gutters, detention ponds, outlets, BMPs) that is intended to carry only stormwater runoff. Separate storm sewer systems are not combined with sanitary sewer systems and generally discharge directly to a stream. The MS4 program requires regulated municipalities to develop and implement a stormwater management program that addresses six Minimum Control Measures (MCMs) for municipally owned or operated systems. The MCMs are:
1. Public Education
2. Public Participation
3. Illicit Discharge Detection and Elimination
4. Construction Site Stormwater Management
5. Post-Construction Stormwater Management
6. Pollution Prevention and Good Housekeeping at Municipal Facilities
Public input, comments and suggestions on the MS4 Implementation Plan or other stormwater related issues is welcome. Copies of the plan, annual report and attachments are available on this website (see below), at the Conservation District office, or by mail upon request.
