# §51.1112. Requirements for reasonably available control technology (RACT) and reasonably available control measures (RACM).

- (a) **RACT requirement for areas classified pursuant to § 51.1103.**
  - (1) For each nonattainment area classified Moderate or higher, the state shall submit a SIP revision that meets the VOC and NOX RACT requirements in CAA sections [182(b)(2)](/cfr/40/182.md?p=b-2) and [182(f)](/cfr/40/182.md?p=f).
  - (2) The state shall submit the RACT SIP for each area no later than 24 months after the effective date of designation for the 2008 ozone NAAQS.
  - (3) The state shall provide for implementation of RACT as expeditiously as practicable but no later than January 1 of the 5th year after the effective date of designation for the 2008 ozone NAAQS.
- (b) **Determination of major stationary sources for applicability of RACT provisions.** The amount of VOC and NOX emissions are to be considered separately for purposes of determining whether a source is a major stationary source as defined in CAA [section 302](/cfr/40/302.md).
- (c) **Reasonably Available Control Measures (RACM) requirement.** For each nonattainment area required to submit an attainment demonstration under § [51.1108(a)](/cfr/40/51.1108.md?p=a) and [(b)](/cfr/40/51.1108.md?p=b), the state shall submit with the attainment demonstration a SIP revision demonstrating that it has adopted all RACM necessary to demonstrate attainment as expeditiously as practicable and to meet any RFP requirements.
