§ 51.1009 Moderate area attainment plan control strategy requirements.

(a) The state shall identify, adopt, and implement control measures, including control technologies, on sources of direct PM_2.5 emissions and sources of emissions of PM_2.5 plan precursors located in any Moderate PM_2.5 nonattainment area or portion thereof located within the state consistent with the following:

(1) The state shall identify all sources of direct PM_2.5 emissions and all sources of emissions of PM_2.5 precursors in the nonattainment area in accordance with the emissions inventory requirements of § 51.1008(a).

(2) The state shall identify all potential control measures to reduce emissions from all sources of direct PM_2.5 emissions and all sources of emissions of PM_2.5 plan precursors in the nonattainment area identified under paragraph (a)(1) of this section.

(i) The state is not required to identify and evaluate potential control measures to reduce emissions of a particular PM_2.5 precursor from any existing sources if the state has submitted a comprehensive precursor demonstration approved by the EPA pursuant to § 51.1006, except where the EPA requires such information as necessary to evaluate the comprehensive precursor demonstration pursuant to § 51.1006(a)(1)(ii).

(ii) The state is not required to identify and evaluate potential control measures to reduce emissions of a particular PM_2.5 precursor from any existing major stationary sources if the state has submitted a major stationary source precursor demonstration approved by the EPA pursuant to § 51.1006, except where the EPA requires such information as necessary to evaluate the major stationary source precursor demonstration pursuant to § 51.1006(a)(1)(ii).
