Section 13.0 Reasonably Available Control Measures (RACM)
Sections 172(a)(2)(A) and 181(a) of the CAA require ozone non-attainment areas to attain the NAAQS as expeditiously as practicable, including such reductions as may be obtained through RACT, and to provide outer-limit dates for attainment based on an area's classification. Furthermore, CAA Section 172(c)(1) states, "IN GENERAL - Such plan provisions shall provide for the implementation of all reasonably available control measures as expeditiously as practicable (including such reductions in emissions from existing sources in the area as may be obtained through the adoption, at a minimum, of reasonably available control technology) and shall provide for attainment of the national primary ambient air quality standards." The Department submitted a RACT SIP revision to EPA on September 15, 2006.
The RACM requirement applies to all non-attainment areas that are required to submit an attainment demonstration, whether covered under only CAA Subpart 1 or also Subpart 2.
EPA issued several guidance documents for implementing the RACM provisions of the CAA that interpret that provision to require a demonstration that the state has adopted all reasonable measures to meet RFP requirements and to demonstrate attainment as expeditiously as practicable and thus, that no additional measures that are reasonably available will advance the attainment date or contribute to RFP for the area:
- "State Implementation Plans; General Preamble for Proposed Rulemaking on Approval of Plan Revisions for Nonattainment Areas" (44 FR 20372 - 20375).
- "State Implementation Plans; General Preamble for the Implementation of Title I of the Clean Air Act Amendments of 1990; Proposed Rule" (57 FR 13498 - 13560 (April 16, 1992)).

OTC staff and member states, including New York, formed and participated in several workgroups to identify and evaluate candidate control measures that could be used to demonstrate attainment of the 8-hour ozone NAAQS. Initially, the workgroups compiled and reviewed a list of approximately 1,000 candidate control measures. These control measures were identified through published sources such as EPA's CTGs, National Association of Clean Air Agencies (NACAA) "Menu of Options" documents, the AirControlNET database, emission control initiatives in member states as well as other states including California, state/regional consultations, and stakeholder input. The workgroups evaluated data regarding emissions benefits, cost-effectiveness (economic feasibility) and implementation issues (technological feasibility) to develop a preliminary list of 30 candidate control measures to be considered for more detailed analysis. These measures were selected to focus on the pollutants and source categories that are thought to be the most effective in reducing ozone levels in the Northeastern and Mid-Atlantic regions. "Identification and Evaluation of Candidate Control Measures - Final Technical Support Document," dated February 28, 2007 is included in this SIP revision as an Appendix as supporting documentation of the process and product of the workgroups.
Based on the analysis conducted by the workgroups, the OTC Commissioners recommended that states consider reductions from the following source categories:
Portable Fuel Containers
Adhesives and Sealants Applications
Diesel Engine Chip Reflash
Cutback and Emulsified Asphalt Paving
Asphalt Production Plants
Industrial, Commercial and Institutional (ICI) Boilers
With the exception of Diesel Engine Chip Reflash and Regional Fuels, the State of New York is developing new or revised regulations for all of the source categories recommended by the OTC Commissioners that will provide for the implementation of all reasonably available control measures and attainment of the NAAQS as expeditiously as practicable. Hence, New York State believes that these measures represent RACM as they are reasonably available and can be expected to advance the attainment date and contribute to RFP. These measures, referred to as "Beyond On The Way" measures in the modeling scenarios, are anticipated to provide an additional 1 to 2 ppb reduction benefit in the projected 2009 design values beyond what was projected for "On The Books/On the Way" measures as detailed in the modeling section of this SIP.
