Environmental Protection Agency November 18, 2014 – Federal Register Recent Federal Regulation Documents

Approval and Promulgation of Implementation Plans; Mississippi; Infrastructure Requirements for the 2008 Lead National Ambient Air Quality Standards
Document Number: 2014-27268
Type: Proposed Rule
Date: 2014-11-18
Agency: Environmental Protection Agency
The Environmental Protection Agency (EPA) is proposing to approve in part and disapprove in part the November 17, 2011, State Implementation Plan (SIP) submission, provided by the Mississippi Department of Environmental Quality (MDEQ) for inclusion into the Mississippi SIP. This proposal pertains to the Clean Air Act (CAA or the Act) infrastructure requirements for the 2008 Lead national ambient air quality standards (NAAQS). The CAA requires that each state adopt and submit a SIP for the implementation, maintenance, and enforcement of each NAAQS promulgated by EPA, which is commonly referred to as an ``infrastructure'' SIP. MDEQ certified that the Mississippi SIP contains provisions that ensure the 2008 Lead NAAQS is implemented, enforced, and maintained in Mississippi (hereafter referred to as an ``infrastructure SIP submission''). With the exception of provisions pertaining to prevention of significant deterioration (PSD) permitting and the state board majority requirements respecting significant portion of income, EPA is proposing to determine that Mississippi's infrastructure SIP submission, provided to EPA on November 17, 2011, addresses the required infrastructure elements for the 2008 Lead NAAQS.
