The EPA is proposing to take action on a petition for rulemaking filed by the Sierra Club in 2011 concerning the treatment of excess emissions in state rules by sources during periods of startup, shutdown, or malfunction (SSM). EPA is proposing to grant in part and to deny in part the request to rescind its policy interpreting the Clean Air Act (CAA) to allow states to have appropriately drawn state implementation plan (SIP) provisions that provide affirmative defenses to monetary penalties for violations during periods of SSM. The EPA is also proposing either to grant or to deny the Petition regarding existing SIP provisions related to SSM in each of 39 states identified in the petition.
For each of those states where EPA proposes to grant the petition concerning specific provisions, EPA also is proposing to find that the existing SIP provision is substantially inadequate to meet CAA requirements and proposes a “SIP call.” For those affected states EPA will require the states to submit a corrective SIP revision. Comments on the proposed actions must be received on or before March 25, 2013.
Through this rulemaking, EPA intends to clarify its interpretation of the CAA regarding excess emissions during SSM events. EPA may find specific SIP provisions to be substantially inadequate to meet CAA requirements; if a state’s existing SIP provision allows an automatic exemption for excess emissions during periods of startup, shutdown, or malfunction, then the EPA may determine that the SIP provision is substantially inadequate because the provision is inconsistent with requirements of the CAA.
The affected States include:
District of Columbia
