On Dec. 13, 2013 EPA, DENR Secretary John Skvarla sent a letter to EPA requesting that they designate all townships in all counties in North Carolina to be in attainment for the 2012 annual PM2.5 standard.
Sec. Skvarla wrote in the letter:
"Based on the 2010 - 2012 ambient monitoring data, all counties in North Carolina are below the annual PM2.5 NAAQS... It is North Carolina's recommendation that, since there is no evidence of violations, all townships in all counties in North Carolina be designated as "attainment" for the revised annual PM2.5 standard."
"We are requesting township level designation due to potential implications for the Prevention of Significant Deterioration permitting program of having an entire county designated as a single area rather than smaller areas (e.g., partial counties). North Carolina requests that EPA also revise the current designations for the 24-hour PM2.5 standard so that the annual PM2.5 and the 24-hour PM2.5 designations are on the township basis."
