EPA Backs Pennsylvania's Plans for Cleaner Air Through 2035
Published Date: 4/7/2025
Proposed Rule
Summary
The EPA is giving a thumbs-up to Pennsylvania’s plan to officially say the air in Liberty-Clairton meets important clean air standards and will stay that way through 2035. They’re also approving a plan to keep Allegheny County’s air clean through 2035, including rules for vehicle pollution. This means cleaner air for local communities with no new costs, just smart planning for the future.
Analyzed Economic Effects
3 provisions identified: 2 benefits, 1 costs, 0 mixed.
Liberty‑Clairton Redesignated to Attainment
If you live in the Liberty‑Clairton area, EPA is proposing to redesignate the area to attainment for the 1997 annual and 2006 24‑hour PM2.5 standards and to approve Pennsylvania’s plan to maintain those standards through 2035.
Allegheny County PM2.5 Maintenance Plan Approved
EPA is proposing to approve Allegheny County’s maintenance plan for the 2012 annual PM2.5 standard through 2035 and to find adequate and approve the mobile vehicle emissions budgets (MVEBs) for 2017, 2026, and 2035 for PM2.5 and NOx into Pennsylvania’s SIP for transportation conformity.
Allegheny Redesignation Not Occurring
EPA notes that this action does not redesignate the Allegheny County area to attainment for the 2012 annual PM2.5 standard because Pennsylvania withdrew its redesignation request for the Allegheny County area.
