 PUBLIC LAW 101-549—NOV. 15, 1990 104 STAT. 2703 "(iii) consider realistic behavior of aerosols by including physicochemical reactions with water vapor, ground deposition, and removal by water spray; "(B) evaluate existing and future atmospheric dispersion models by— "(i) the development of a rigorous, standardized methodology for dense gas models; and "(ii) the application of such methodology to current dense gas dispersion models using data generated from field experiments; and "(C) evaluate the effectiveness of hazard mitigation and emergency response technology for fixed site and transportation related accidental releases of toxic chemicals. Models pertaining to accidental release shall be evaluated and improved periodically for their utility in planning and implementing evacuation procedures and other mitigative strategies designed to minimize human exposure to hazardous air pollutants released accidentally. "(3) The Secretary of Energy shall make available to interested persons (including other Federal agencies and businesses) the use of the Liquefied Gaseous Fuels Spill Test Facility to conduct research and other activities in connection with the activities described in this subsection.". (c) ADDITIONAL PROVISIONS.— Section 103 of the Clean Air Act is 42 USC 7403. amended by inserting after subsection (f) the following: "(g) POLLUTION PREVENTION AND EMISSIONS CONTROL. — In carry- ing out subsection (a), the Administrator shall conduct a basic engineering research and technology program to develop, evaluate, and demonstrate nonregulatory strategies and technologies for air pollution prevention. Such strategies and technologies shall be developed with priority on those pollutants which pose a significant risk to human health and the environment, and with opportunities for participation by industry, public interest groups, scientists, and other interested persons in the development of such strategies and technologies. Such program shall include the following elements: "(1) Improvements in nonregulatory strategies and technologies for preventing or reducing multiple air pollutants, including sulfur oxides, nitrogen oxides, heavy metals, PM-1 (particulate matter), carbon monoxide, and carbon dioxide, from stationary sources, including fossil fuel power plants. Such strategies and technologies shall include improvements in the relative cost effectiveness and long-range implications of various air pollutant reduction and nonregulatory control strategies such as energy conservation, including end-use efficiency, and fuel-switching to cleaner fuels. Such strategies and technologies shall be considered for existing and new facilities. "(2) Improvements in nonregulatory strategies and technologies for reducing air emissions from area sources. "(3) Improvements in nonregulatory strategies and technologies for preventing, detecting, and correcting accidental releases of hazardous air pollutants. "(4) Improvements in nonregulatory strategies and technologies that dispose of tires in ways that avoid adverse air quality impacts. Nothing in this subsection shall be construed to authorize the imposition on any person of air pollution control requirements. The Administrator shall consult with other appropriate Federal agencies
