State and federal regulations require more urbanized communities like Windham to implement the following
six Minimum Control Measures (MCMs) to significantly reduce the discharge of pollutants into local waterways. The Town is required to develop a detailed Stormwater Program Management Plan that describes how each of the MCMs will be implemented over the five year permit period. Each of these MCMs is targeted towards specific audiences and activities as briefly described below:
MCM1. Public Education and Outreach: distribute educational materials and conduct public outreach to inform citizens about the impacts polluted stormwater on receiving water quality.
MCM2. Public Participation and Involvement: provide opportunities for citizens to participate in stormwater management program development and implementation.
MCM3. Illicit Discharge Detection and Elimination: develop and implement an enforceable plan to conduct routine inspections of stormwater systems to eliminate illicit pollutant discharges to receiving waters.
MCM4. Construction Site Runoff Control: develop and implement an enforceable plan to minimize sediment transport to receiving waters from construction activities disturbing more than 1 acre of land.
MCM5. Post-Construction Runoff Control: develop and implement an enforceable plan to minimize polluted stormwater runoff to receiving waters from new development or redevelopment projects.
MCM6. Pollution Prevention and Good Housekeeping: develop and implement a training program to minimize stormwater pollution from municipal activities.
