Helena — The Montana Department of Environmental Quality (DEQ) is inviting public comment on a proposed Request for Redesignation of the Yellowstone County SO2 nonattainment area and a proposed Yellowstone County attainment area Maintenance Plan. The proposal will be submitted to the Environmental Protection Agency (EPA) as a revision to the Montana State Implementation Plan (SIP).

Since that time, the nonattainment area has attained the SO2 NAAQS and DEQ has demonstrated that the area will maintain compliance according to the Maintenance Plan.
