Approval and Promulgation of Implementation Plans and Designation of Areas for Air Quality Planning Purposes; Ohio

Краткое содержание

The Environmental Protection Agency is approving maintenance plans and redesignation of Morgan and Washington Counties, Ohio, from nonattainment to attainment for sulfur dioxide (SO 2), and is deferring action on the maintenance plans and redesignation request for Gallia and Coshocton Counties. This action for Morgan and Washington Counties is based on Ohio's request, and provides that the new source review requirements for nonattainment areas will no longer apply for SO 2 in these two counties.
