Show committee is made up of a diverse representation of affected stakeholders to ensure a balanced approach to the rulemaking process. Currently, the Coordinating Committee is comprised of an E P A co-chair and representatives from state and local governments, labor, large industry trade organizations (such as the American Petroleum Institute, Chemical Manufacturers Association, the American Boiler Manufacturers Association, and the Engine Manufacturers Association), environmental groups (such as the Sierra Club and the National Audubon Society), and several large energy, chemical, and oil producers. Although the Coordinating Committee is charged with making regulatory recommendations, ultimate rulemaking authority rests with the EPA. The Coordinating Committee is also responsible for providing direction to the individual work groups. There are seven work groups in the I C C R organization; five for each of the regulated source groups (boilers, incinerators, process heaters, stationary internal combustion engines, and stationary gas turbines) and one each for testing and monitoring protocol development and economic analysis. The work groups are comprised of an E P A co-chair and representatives of affected stakeholders w h o have a particular expertise or interest in a particular source category. Source work groups are responsible for initiating information collection and analysis, identifying regulatory alternatives, and making preliminary regulatory recommendations for their source category. The testing and monitoring protocol and economic analysis work groups provide technical expertise to the source work groups in the analysis of data and calculation of the economic impacts of proposed regulations. Scope of Regulatory Development The ICCR process will develop regulations for combustion sources under Section 112 and 129 of the Clean Air Act. Additionally, existing N S P S regulations (Section 111 of the Clean Air Act, codified in 40 C F R 60) will be reviewed and updated. The affected source categories and applicable regulations are reviewed below and summarized in Table 1. Fossil fuel-fired electric utilities are not part of the I C C R process because they are being regulated separately. Furthermore, issues such as acid rain, ozone N A A Q S (National Ambient Air Quality Standards) attainment, and the health effects of fine particulate matter are being addressed by other Clean Air Act rulemaking programs and therefore, will not be addressed by the ICCR. ICCR participants will, however, coordinate with these programs to avoid the promulgation of conflicting regulations. Section 112 - National Emission Standards for Hazardous Air Pollutants (NESHAPs) Regulations developed under this section will address combustion emissions of the 188 HAPs listed in the act as hazardous or toxic.1 These standards will cover n e w and existing sources, although standards for n e w sources m a y differ from those for existing sources. Rules promulgated under Section 112 must include emission limits that reflect the use of maximum achievable control technology ( M A C T ) . The emission limits will apply to sources or a group of sources under c o m m o n control that emits 10 tpy (tons per year) of any single H A P or 25 tpy of any combination of H A P s (these sources are termed "major sources"). M A C T is defined in Section 112 as the maximum reduction in emissions achievable, considering the cost, environmental, and energy impacts and can be no less stringent than a level which is termed the M A C T floor. The M A C T floor is defined for existing emission sources as "the average limitation achieved by the best performing 12 percent of existing sources". The M A C T floor for new sources is defined as the "emission control that is achieved in practice by the best controlled similar source". Under Section 112, emission limits can be set more stringent 1 Originally the Clean Air Act listed 189 HAPs. However on 6/18/96, the chemical caprolactum was removed from the list. |
