Municipal MS4 Compliance

• MCM 1: Establish a Public Education and Outreach Program with the focus on connecting local waterway impairment(s) to target audience group(s) and developing long-term goals and short-term objectives for the MS4 Program.
• MCM 2: Create a Public Involvement and Participation Program that reaches the municipal target audience group(s) and provides a means for public outreach and an evaluation of those efforts.
• MCM 3: Develop an Illicit Discharge, Detection, and Elimination Program to address inspections, reporting and sampling associated with illicit discharges in the municipality.  A significant portion of this program revolves around the municipality’s stormwater water conveyance system (storm sewer and surface features such as swales) therefore a system map is created and functions as a tool for addressing system maintenance as well as emergency discharge situations.
• MCM 4: If not already in place, assist with establishing a Memorandum of Understanding with the local conservation district. Define additional procedures for the municipality to ensure compliance with 25 Pa Code Chapter 102, related to erosion and sediment control.
• MCM 5: Define procedures and a tracking mechanism for post constructions Best Management Practices.
• MCM 6: Develop standard operating procedures for all municipal properties and activities.
