Key Facts

Plan threshold: 5,000 square feet
Permit threshold: One acre disturbance
Code citation: 25 Pa. Code Ch. 102
Lead agency: DEP and conservation districts

Full Breakdown

Chapter 102, authorized by 35 P.S. Sections 691.1-691.1001, requires best management practices for any earth disturbance regardless of size. Projects disturbing 5,000 square feet or more must have a written E&S plan on site. Disturbances of one acre or more, or any size in special protection waters, require an NPDES Permit for Stormwater Discharges Associated with Construction Activities, administered by DEP and county conservation districts. Plans must address runoff control, sediment basins, and post-construction stormwater management.

Violations & Penalties

Civil penalties up to $10,000 per day, plus daily continuing-violation fines and required restoration, can be assessed under the Clean Streams Law.

Frequently Asked Questions

Do Pennsylvania homeowners need an erosion plan for a small renovation?

Disturbances under 5,000 square feet do not require a written plan, but BMPs to prevent sediment runoff are still required by the Clean Streams Law.

Can a Pennsylvania municipality waive the state erosion permit requirement?

No. Chapter 102 NPDES permits are state-administered. Local approvals do not substitute for the DEP or conservation district permit on qualifying projects.
