"(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
amended by inserting after subsection (f) the following:
"(g) Pollution Prevention and Emissions Control.-In carrying
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-10 (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 to ensure coordination and to avoid duplication of
activities authorized under this subsection.
