Print Friendly, PDF & Email

NOTICE IS HEREBY GIVEN that the Council of North Wales Borough (Borough) will receive public comment(s) on the proposed North Wales Borough Wissahickon Creek TMDL Plan / Nutrient Pollutant Reduction Plan (PRP) required by the Individual MS4 Permit. The proposed TMDL Plan / PRP includes:

  • Identification of North Wales Borough’s required reductions from the Waste Load Allocation (WLA) identified within the EPA’s Wissahickon Creek TMDL;
  • Identification and locations of structural Best Management Practices (BMPs) for implementation during the permit period to reduce loadings of nutrients and sediment as required by the Individual MS4 Permit to meet the TMDL / PRP requirements;
  • Explanation of the methodology used to calculate existing sediment loadings and corresponding reductions from applicable watersheds with regulated MS4; and
  • Locations of the Borough’s MS4 infrastructure and local waterways with nutrients/sediment impairments.

BACKGROUND INFORMATION

The Pennsylvania Department of Environmental Protection (PADEP) adopted and issued the revised Small MS4 Individual Permit (IP). An IP is required for municipalities where a TMDL with an applicable WLA on MS4 discharges have been established. The revised MS4 Permit also includes requirements for the development and implementation of a PRP for local waterways receiving discharges from the regulated MS4 with nutrients and/or sediment impairments, and a CBPRP for municipalities located in the Chesapeake Bay drainage basin. The Borough is not located in the Chesapeake Bay drainage basin, therefore, a CBPRP is not required.  

For the PRP, the Borough is required to reduce existing loadings of nutrients for locally impaired waterways from its regulated MS4 during the current 5-year MS4 Permit cycle as follows:

                (1) 10% reduction in sediment, and

                (2) 5% reduction in Total Phosphorus.

For the TMDL, the Borough is required to reduce existing sediment loadings to local waterways from its regulated MS4 during the current 5-year MS4 Permit cycle as follows:

  • 10% reduction in sediment

Long-term sediment load reductions are also part of the TMDL requirements for the Borough; however, only a minimum 10% reduction is required during the current permit cycle. 

The TMDL Plan / PRP can and are combined into a single document.
