Environmental Protection Agency April 16, 2014 – Federal Register Recent Federal Regulation Documents

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).
