High impactFederalProposed
EPA is deciding which areas fail the 2024 annual PM2.5 standard of 9.0 micrograms per cubic meter. Final designations are due by February 6, 2027 under a court order. Pennsylvania recommended nonattainment for eight counties; EPA's letter to New Jersey names four South Jersey counties in the multi-state Philadelphia area. EPA told New York and Connecticut they have no affected monitors.

Electric vehicle make-ready parking for new development
Medium impact
State law requires new multifamily projects to make 15% of required parking EV-ready at preliminary site plan approval, with chargers installed in a third of those at once and the rest within three and six years of the certificate of occupancy. Other parking lots need set numbers of make-ready spaces. Towns cannot require more.

High impactFederal
Under the 2025 budget law, wind and solar projects lose the clean electricity credits unless construction began by July 4, 2026 or they are placed in service by December 31, 2027. A federal court vacated the IRS notice limiting how construction can be shown (June 6, 2026), restoring the 5% safe harbor for now.
