Municipal MS4 Compliance

Long before Pa DEP implemented its Municipal Separate Storm Sewer Systems (MS4) Program, ARRO assisted its municipal clients in addressing their stormwater problems. ARRO has provided site evaluations, remedial designs, green infrastructure projects, floodplain and stormwater ordinance creation and revisions, and reviewed countless stormwater reports with land development plans.

ARRO developed several MS4 programs for municipalities and continues, in various capacities, to assist with MS4 Program compliance. 

CLIENT/LOCATION
Various Municipalities in PA & MD

SCOPE OF WORK
Development and implementation assistance of MS4 programs for municipalities. 

  • 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.
