Explanation

Wetlands are regulated under Section 404 of the federal Clean Water Act (Army Corps of Engineers permitting) and Pennsylvania's Clean Streams Law and Dam Safety Act (PADEP permits). Filling or altering wetlands without permits triggers enforcement, cleanup orders, and significant fines. Pennsylvania has extensive wetlands in its coastal plain, river valleys, and northern tier. Buyers and developers must conduct wetlands delineations before planning development to avoid costly surprises.
