Annual MS4 compliance activities are ongoing and will continue throughout 2026. The Township’s NPDES MS4 Permit, issued by the Pennsylvania Department of Environmental Protection (PaDEP), requires the Township to annually comply with six Minimum Control Measures (MCMs). The MCMs have been established by PaDEP to meet permit goals and to preserve and improve surface water quality – streams, lakes, and rivers. The Township’s MS4 Permit requires implementation of a stormwater management program that addresses each of the six MCMs identified in the permit, as follows:
• MCM #1: Public Education and Outreach regarding Stormwater Impacts
• MCM #2: Public Involvement and Participation
• MCM #3: Illicit Discharge Detection and Elimination
• MCM #4: Construction Site Stormwater Runoff Control
• MCM #5: Post-Construction Stormwater Management in New and Re-Development Activities
• MCM #6: Pollution Prevention and Good
Housekeeping for Municipal Operations - MCM Nos. 1 and 2 implement a Public Education and Public Involvement Program. The goal of these MCMs is to solicit community involvement in the Township’s MS4 program as well as continuing to educate the community relative to MS4 and stormwater initiatives. Part of the ongoing MS4 education program includes regular MS4 updates in the Township newsletter as well as regular discussion at the Board of Supervisors meetings. The Township also advertises several recycling events throughout the year for residents to participate in, as well as providing a brush/grass clippings bin for residents to utilize to properly dispose of. All of these initiatives are included on the Township website, which includes a dedicated stormwater management / MS4 page which includes the most up to date information relative to the Township’s permit.
The Township implements an Illicit Discharge Detection and Elimination Program to comply with the requirements of MCM #3. This program includes an annual outfall screening program, where the Township Engineer completes a review of the outfalls in the Township.
The purpose of this program is to identify and eliminate illicit discharges that may contribute pollutants to the Township’s streams and lakes. This program is conducted during late spring/summer months at times of dry weather; samples are collected from the outfalls and are tested to determine if any pollutants are present in the discharge. If a pollutant is found, the Township investigates to determine the source of the pollutant and works towards removing it from entering the storm sewer system.
MCM #5 requires the Township to ensure adequate operation and maintenance of post-constructionstormwater best management practices (PCSM BMPs) throughout the Township. PCSM BMPs are facilities that control or treat stormwater runoff, such as detention basins, rain gardens, bioretention basins, underground stormwater detention tanks, and other stormwater control facilities. In order to evaluate whether these facilities are operating properly, representatives of the Township and Township Engineer complete annual field reviews of each BMP during the spring. This includes both BMPs owned by the Township and those owned by private entities, including developers, businesses, homeowners’ associations and other entities. When deficiencies are found during the inspection, parties responsible for maintenance are notified to take corrective action such that the BMPs function as designed to address downstream flooding and improve water quality. The Township provides notice to the parties responsible for maintenance in advance of the inspections in the event the party responsible would like to be in attendance at the time of the inspection.
As part of MCM #6, the Township implements an annual training program for Township officials and staff. The training program provides information regarding permit activities and requirements. Specific training is provided annually to Road Department, Municipal Authority and Sanitary Authority staff regarding the Township’s Pollution Prevention and Good Housekeeping Operation and Maintenance Plan. This O&M Plan, developed as a requirement of MCM #6, establishes procedures implemented by the Township to prevent stormwaterpollution during municipal operations. Annual elected official training is regularly held at the February Board of Supervisors Meeting.
