South Dakota’s Regional Haze State Implementation Plan
The following documents represent South Dakota’s Regional Haze State Implementation Plan. DENR submitted the plan to EPA for approval on January 21, 2011. On August 18, 2011, the Board of Minerals and Environment approved revisions to the technical document for the Regional Haze State Implementation Plan and revisions to Administrative Rules of South Dakota, Chapter 74:36:21 – Regional Haze Program. On August 30, 2011, the Interim Rules Committee approved the revisions to the rules and DENR served the Secretary of State. The revisions to the rules will become provisionally effective September 19, 2011. At that time, DENR will submit the revised technical document and rules to EPA for approval of South Dakota’s Regional Haze State Implementation Plan:

EPA promulgated the regional haze rule on July 1, 1999. Under Title 40 of the Code for Federal Regulations (CFR), section 51.308(d)(1), states must “establish goals (expressed in deciviews) that provide for reasonable progress towards achieving natural visibility conditions” for each Class I area within a state by 2064. The proposed rules and South Dakota’s State Implementation Plan for adopting a Regional Haze Program establish the measures South Dakota will take to achieve natural visibility conditions at our Class I areas by 2064.
