Regulatory Context

Pennsylvania regulates wetland impacts primarily through Chapter 105 (waterways and wetlands) administered by PA DEP regional offices. Three USACE districts cover the state, requiring applicants to identify the correct district early. PA DEP uses a statewide wetland mapping database but emphasizes field delineation over map review. The state's Chapter 105 program has independent permit thresholds below the federal Section 404 nationwide permit triggers.
