Federal Register / Vol. 86, No. 156 / Tuesday, August 17, 2021 / Proposed Rules
IV. What action is EPA taking?
EPA is proposing to approve EGLEs request for a Clean Data Determination for the St. Clair nonattainment area in St. Clair County, Michigan. Finalizing this determination would suspend the requirements for EGLE to submit an attainment demonstration and other associated nonattainment planning requirements for so long as the St. Clair nonattainment area continues to attain the 2010 SO2 NAAQS. This proposed action is consistent with EPAs longheld interpretation of CAA
requirements.
Finalizing this action would not constitute a redesignation of the St.
Clair area to attainment of the 2010 SO2
NAAQS under section 107d3 of the CAA. The St. Clair area will remain designated nonattainment for the 2010
SO2 NAAQS until such time as EPA
determines that the area meets the CAA
requirements for redesignation to attainment and takes action to redesignate the area.
