§ 52.119 Identification of plan—conditional approvals.  


Latest version.
  • This section identifies plan revisions that are conditionally approved based upon commitments received from the State.

    (a) A plan revision for the Arizona Department of Environmental Quality (ADEQ) submitted April 28, 2017, by the Governor's designee, updating ADEQ's Clean Air Act (CAA) new source review (NSR) program only with respect to the CAA requirements related to ammonia as a precursor to PM2.5 under the nonattainment NSR program requirements in CAA section 189(e). This plan revision is conditionally approved as follows:

    (1) The conditional approval is based upon the December 6, 2017 commitment from the State to submit a SIP revision to the EPA by March 31, 2019 consisting of rule revisions and/or demonstrations that will correct the deficiencies identified with this submittal, as specified in ADEQ's December 6, 2017 commitment letter. If the State fails to meet its commitment by March 31, 2019, the conditional approval will be treated as a disapproval only with respect to the CAA requirements related to ammonia as a precursor to PM2.5 under the nonattainment NSR program requirements in CAA section 189(e).

    (2) [Reserved]

    (b) A plan revision for the Maricopa County Air Quality Department (MCAQD) submitted May 18, 2016, by the Arizona Department of Environmental Quality (ADEQ), the Governor's designee, updating the MCAQD's Clean Air Act (CAA) new source review (NSR) program with respect to deficiencies identified by the EPA in Regulation I, Rule 100 and Regulation II, Rule 200. This plan revision is conditionally approved as follows:

    (1) The conditional approval is based on the April 6, 2018 and October 5, 2018 commitments from the ADEQ, and on the April 2, 2018 letter from the MCAQD to the ADEQ requesting submittal of a letter of commitment for conditional approval, to submit a SIP revision consisting of rule revisions and/or demonstrations to the ADEQ within eleven (11) months after the EPA's approval, to allow the ADEQ to make the final submission to the EPA not later than twelve (12) months after the EPA's approval that will correct the deficiencies identified in this final notice. If the State fails to meet its commitment by that date that is twelve (12) months after the EPA's approval, the conditional approval will be treated as a disapproval to deficiencies identified by the EPA in Regulation I, Rule 100; and Regulation II, Rule 200.

    (2) [Reserved]
