Purpose of this program:
To assist State, Tribal, Municipal, Intermunicipal, and Interstate agencies in planning, developing, establishing, improving, and maintaining adequate programs for prevention and control of air pollution or implementation of national primary and secondary air quality standards. Funding Priority: Grant funds are targeted to recipients to help EPA address three major priorities in air pollution control: (a) attain and maintain national ambient air quality standards for criteria pollutants (ozone, particulate matter, visibility; carbon monoxide, lead, sulfur dioxide and nitrogen dioxide) which endanger human health (particularly sensitive populations) and the environment; (b) eliminate unacceptable risks of cancer and other health problems from air toxics emissions; and (c) reduce the destructive effects of acid rain deposition on land and water systems formed by ambient nitrates and sulfates. Section 105 provides funds to help states, locals and tribes to address the new standards for ozone and fine particulate matter - assessing transport and regional impacts, characterizing their air quality status, developing attainment plans, and implementing and assessing the effectiveness of control strategies. Strategies include regulation of stationary sources, mobile source emissions testing and trip reduction measures, participation in an interstate emissions trading program, and other innovative early reduction and voluntary measures at the local level. Funds will also go to state, local and Tribal governments to bolster their individual roles in regional efforts to reduce visibility-impairing regional haze. Funds continue to assist states, Tribes and local agencies in implementing strategies to reduce the other criteria pollutants, review data for their designation to attainment, and assist in developing plans, as necessary, to maintain compliance with standards. For air toxics, grants are provided to expand the air toxics monitoring network operated by state, tribal and local agencies in order to better characterize air toxics risks and assess the effectiveness of control strategies. Funds are also provided to help state and other agencies implement maximum achievable control technology standards (MACT) and other air toxics standards affecting the emissions of specific categories of sources. Funds also help carry out national, regional and community-based initiatives that focus on the identification and reduction of residual, multi-media and cumulative air toxics risks. Funds for acid deposition enable states to conduct analyses of the impacts of acid rain on land and water bodies, assess the effectiveness of control strategies and monitor the market-based acid rain trading program involving emissions from electric utilities. Overall, section 105 funds promote not only agency-specific air pollution prevention and control efforts but also efforts intended to address multiple pollutant, cross-media and interstate and trans-boundary.
