Millcreek, PA Environmental Rules: Erosion Control (2026)

Article IV of Chapter 116 of the Millcreek Township Code is short, and § 116-19 does the work. Subsection A requires an erosion/sedimentation plan for each development site, prepared under the Pennsylvania Erosion/Sedimentation Regulations at 25 Pa. Code Chapter 102 and the standards and guidelines of the Erie County Conservation District. Subsection B sends grading plan submission and action to Chapter 125, Subdivision and Land Development, and Chapter 145, Zoning, as they pertain to the development. Subsection C requires the proposed erosion and sedimentation control measures to be submitted together with the stormwater management plan, so one Township review covers both.

The duty continues into construction. Section 116-12B requires erosion and sediment control BMPs to be designed, implemented, operated and maintained during regulated earth disturbance activities, for example during construction, and to meet Title 25 of the Pennsylvania Code, including Chapter 102 and the Clean Streams Law. The code points to the Erosion and Sediment Pollution Control Program Manual, No. 363-2134-008 (April 15, 2000), as amended and updated, for BMP design standards. Section 116-12E asks every regulated activity to minimize soil disturbance and soil compaction and to avoid erosive flow conditions in natural flow pathways.

Several design sections add specific erosion rules. Under § 116-22, surface drainage inlets on infiltration systems must be fitted with sediment control devices, and an infiltration system cannot receive runoff until its entire drainage area has received final stabilization. Section 116-23C requires swales to be properly vegetatively stabilized or otherwise lined to prevent erosion. Section 116-24E requires the siltation facility to precede stormwater entry into a detention basin or outlet structure.

Exemptions are narrow. Section 116-27D exempts forest management and timber operations from the SWM site plan only when they follow 25 Pa. Code Chapter 102, and temporary roadways are not exempt. Agriculture is exempt when operated under a conservation plan or erosion and sedimentation control plan prepared by the County Conservation District (§ 116-27C).
