EPA Withdraws Direct Final Rule for Pennsylvania's Air Quality Implementation Plan Revisions

Summary

The Environmental Protection Agency (EPA) is withdrawing its direct final rule to approve revisions to Pennsylvania's State Implementation Plan (SIP) due to numerical errors in the Motor Vehicle Emissions Budgets (MVEBs) for nitrogen oxides (NOx) and volatile organic compounds (VOCs). EPA will initiate a new rulemaking process for this SIP revision.
