Commission flags major land‑development plans for potential NPDES and missing approvals

Butler County Planning Commission · June 17, 2026

Summary

Staff identified several major plans (including MABT STP Expansion and PA American Water SW) that may require NPDES permits or other missing approvals (DEP sanitary approvals, PennDOT HOP notes, flow capacity letters, perc tests) before final county endorsement.

During review of major plans, staff flagged several submissions that may trigger National Pollutant Discharge Elimination System (NPDES) permitting because of added impermeable surface or site disturbance. The MABT STP Expansion (#26109) and PA American Water SW (#26105) were specifically noted as "may require NPDES Permit due to size of impermeable surface created and/or disturbance (paving and building)."

Staff also repeatedly noted missing or incomplete technical items across major plans: DEP approval for sanitary systems (heritage law office land development), PennDOT HOP driveway notes, flow capacity letters for sewage, missing perc test results, incomplete landowner authorization forms, and unclear easement language. Commissioners voted to release comments to municipalities for major plans so local reviewers can act on these technical deficiencies.
