PUBLIC NOTICE | Proposed Revision to Arizona State Implementation Plan: Demonstration of a Significant Emission Rate for Ammonia
ADEQ welcomes comments on the proposed Arizona State Implementation Plan (SIP) Revision: Demonstration of a Significant Emission Rate for Ammonia. The plan demonstrates, pursuant to 40 C.F.R. § 51.165(a)(13) and 83 Fed. Reg. 19631 (May 4, 2018), that ammonia is not a significant precursor in the formation of secondary PM2.5 and therefore does not contribute to the PM2.5 nonattainment in the State. Therefore, ADEQ is proposing that establishing a significant emission rate for ammonia as a PM2.5 precursor is unnecessary pursuant to 40 C.F.R. § 51.165(a)(13).
