§ 51.1310 Requirements for reasonable further progress (RFP).
(a) RFP for nonattainment areas classified pursuant to § 51.1303. The RFP requirements specified in CAA section 182 for that area's classification shall apply.
(1) Submission deadline. For each area classified Moderate or higher pursuant to § 51.1303, the state shall submit a SIP revision no later than 36 months after the effective date of designation as nonattainment for the 2015 ozone NAAQS that provides for RFP as described in paragraphs (a)(2) through (4) of this section.
(2) RFP requirements for areas with an approved prior ozone NAAQS 15 percent VOC ROP plan. An area classified Moderate or higher that has the same boundaries as an area, or is entirely composed of several areas or portions of areas, for which the EPA fully approved a 15 percent plan for a prior ozone NAAQS is considered to have met the requirements of CAA section 182(b)(1) for the 2015 ozone NAAQS and instead:
(i) If classified Moderate, the area is subject to the RFP requirements under CAA section 172(c)(2) and shall submit a SIP revision that:

(B) Relies on either NOX or VOC emissions reductions (or a combination) to meet the requirements of paragraph (a)(2)(i)(A) of this section. Use of NOX emissions reductions must meet the criteria in CAA section 182(c)(2)(C).
(ii) If classified Serious or higher, the area is subject to RFP under CAA sections 172(c)(2) and 182(c)(2)(B), and shall submit a SIP revision no later than 48 months after the effective date of designation providing for an average emissions reduction of 3 percent per year:
