The Environmental Protection Agency (EPA or the ``Agency'') is proposing approval of South Dakota's submittal requesting that EPA recognize the merger of South Dakota's Department of Agriculture (DOA) with the Department of Environment and Natural Resources (DENR) to form the new Department of Agriculture and Natural Resources (DANR) and incorporate corresponding non-substantive revisions to the South Dakota Codified Law (SDCL) and the Administrative Rules of South Dakota (ARSD) into South Dakota's State Implementation Plan. Accordingly, EPA is proposing to approve South Dakota's submittal in accordance with the Clean Air Act (CAA).
