Upper Darby, PA Environmental Rules: Erosion Control (2026)

Section 465-16 of Chapter 465, Upper Darby's Stormwater Management Ordinance (adopted 2005, re-enacted 2022), sets the erosion and sediment control rules that apply during construction. No regulated earth disturbance activity may start until the Pennsylvania Department of Environmental Protection approves an erosion and sediment control plan under Title 25 Chapter 102, and, separately, the applicant secures a grading and erosion control permit from the municipality where the project sits. Larger sites also need a PADEP 'NPDES Construction Activities' permit under Title 25 Chapter 92; obtaining that permit, or coverage under the statewide general permit PAG-2, satisfies the plan-submission requirement of § 465-27A.

The applicant must give the Township evidence of every required permit from the PADEP regional office or the County Conservation District, and a copy of the approved erosion and sediment control plan, along with any permit, must stay on the project site at all times so it is available for inspection. Where infiltration BMPs are proposed, § 465-16F adds two more construction-phase duties: the infiltration area must be protected from sedimentation and compaction throughout construction, and it cannot be built or receive runoff until its entire contributing drainage area has reached final stabilization.

Because these are earth-disturbance rules under the same chapter as the Township's broader stormwater program, a contractor grading near a stream still owes the 25-foot drainage easement required by § 465-14H, and § 465-50A(3) lets the Township suspend a permit outright if construction creates a hazard, nuisance or pollution.
