Excess Emissions During Periods of Startup, Shutdown, and Malfunction; Partial Withdrawals of Findings of Failure To Submit State Implementation Plan (SIP)

The Environmental Protection Agency (EPA) is taking direct final action to partially withdraw two final actions finding that 13 States and/or local air pollution control agencies failed to submit State Implementation Plan (SIP) revisions required by the Clean Air Act (CAA) in a timely manner to address the EPA's 2015 findings of substantial inadequacy and "SIP calls" for provisions applying to excess emissions during periods of startup, shutdown, and malfunction (SSM). This final action would render no longer applicable certain CAA deadlines for the EPA to impose sanctions if a State does not submit a complete SIP revision addressing the outstanding requirements and to promulgate a Federal Implementation Plan (FIP). Concurrently, the EPA is also issuing a parallel proposal of this withdrawal action. See the proposed action published in the Proposed Rules section of this issue of the Federal Register.
