Approval and Promulgation of Implementation Plans; State of Missouri, Construction Permits Required

The Environmental Protection Agency (EPA) is proposing to approve revisions to the State Implementation Plan (SIP) for the State of Missouri submitted on October 2, 2013. This proposed rulemaking will amend the SIP to update the construction permits rule to incorporate by reference recent EPA actions related to plantwide applicability limitations (PALs) for greenhouse gases (GHGs) and to correct the definition of ``regulated NSR pollutant.'' Other revisions include modifying the notification period for initial equipment start-up and clarifying de minimis permit air quality analysis requirements.
