Proposed Rule
Summary
The EPA is proposing to approve updates to air pollution controls for the Equitrans Hartson Compressor Station in Pennsylvania.

People can send their thoughts by August 24, 2026, and no new costs are expected from this update.
Analyzed Economic Effects
2 provisions identified: 2 benefits, 0 costs, 0 mixed.
Large NOX Cut at Hartson Station
The EPA is proposing to approve Pennsylvania's revision that removes a 5,000-hour operating cap and lowers permitted NOX limits for the Equitrans Hartson Compressor Station. The short-term NOX limit drops from 43 lb/hr to 5.95 lb/hr and the annual limit drops from about 108 tons/year to about 26.07 tons/year (permit revised February 21, 2023; SIP submitted January 21, 2025).
No New Small-Business Costs Expected
The EPA states this proposed SIP revision merely approves State law and ‘‘does not impose additional requirements beyond those imposed by State law’’ and it is certified as not having a significant economic impact on a substantial number of small entities. The EPA is soliciting comments on the proposal; comments are due August 24, 2026.
