On December 14, 2015, the State of Montana submitted a request for the Environmental Protection Agency (EPA) to redesignate the Billings, Montana, 2010 sulfur dioxide (SO<INF>2</INF>) National Ambient Air Quality Standard (NAAQS) nonattainment area to attainment and to approve a State Implementation Plan (SIP) revision containing a maintenance plan for the area.
