Approval and Promulgation of Air Quality Implementation Plans; Indiana; Particulate Matter Limitations for Coating Operations
The Environmental Protection Agency (EPA) is proposing to approve a revision to the Indiana State Implementation Plan (SIP) under the Clean Air Act (CAA). The particulate matter (PM) rules that were submitted consist of emission control requirements for coating operations along with exemptions from certain coating operations that produce minimal PM emissions. EPA is also proposing to take no action on one section submitted by Indiana, as it pertains to a definition in an unapproved portion of Indiana's Title V regulations. Indiana submitted this request to approve PM rules on April 27, 2012.
Partial Approval and Partial Disapproval and Promulgation of Air Quality Implementation Plans; South Dakota; Revisions to South Dakota Administrative Code; Permit: New and Modified Sources
The Environmental Protection Agency (EPA) is proposing to partially approve and partially disapprove State Implementation Plan (SIP) revisions submitted by the State of South Dakota on June 14, 2010, June 20, 2011, and July 29, 2013. All three SIP revisions revise the Administrative Rules of South Dakota (ARSD) that pertain to the issuance of South Dakota air quality permits; in addition the June 14, 2010 submittal revises certain definitions and dates of incorporation by reference. The June 14, 2010 revisions contain new, amended and renumbered rules; the June 20, 2011 revisions contain new rules, and the July 29, 2013 revisions contain amended rules. In this proposed rulemaking, we are taking action on the entire June 14, 2010 submittal, except for those portions of the submittal which do not belong in the SIP. We are also taking action on portions of the June 20, 2011 submittal that were not acted on in other rulemaking regarding greenhouse gases and the State's Prevention of Significant Deterioration (PSD) program. We are taking action on portions of the July 29, 2013 submittal that supersede portions of the two previous submittals; the remainder of the July 29, 2013 submittal will be acted on at a later date. This action is being taken under section 110 of the Clean Air Act (CAA).
