EPA Withdraws Approval of California's Air Quality Plan Due to Failure to Submit Required Revisions
Summary
The Environmental Protection Agency (EPA) has withdrawn its approval of California's State Implementation Plan (SIP) revisions to reduce ozone pollution in the San Joaquin Valley, citing the state's failure to submit required plans. This decision triggers a 18-month time clock for EPA to impose sanctions and a two-year time clock for the agency to develop federal implementation plans.
