Findings and purposes
Findings
The Congress finds that—
the presence of acidic compounds and their precursors in the atmosphere and in deposition from the atmosphere represents a threat to natural resources, ecosystems, materials, visibility, and public health;
the principal sources of the acidic compounds and their precursors in the atmosphere are emissions of sulfur and nitrogen oxides from the combustion of fossil fuels;
the problem of acid deposition is of national and international significance;
strategies and technologies for the control of precursors to acid deposition exist now that are economically feasible, and improved methods are expected to become increasingly available over the next decade;
current and future generations of Americans will be adversely affected by delaying measures to remedy the problem;
reduction of total atmospheric loading of sulfur dioxide and nitrogen oxides will enhance protection of the public health and welfare and the environment; and
control measures to reduce precursor emissions from steam-electric generating units should be initiated without delay.

Report.—
Not later than
5.60 Million Ton Cap.—
Whenever the inventory required by this section indicates that sulfur dioxide emissions from industrial sources, including units subject to section 405(g)(5) of the Clean Air Act [42 U.S.C. 7651d(g)(5)], may reasonably be expected to reach levels greater than 5.60 million tons per year, the Administrator of the Environmental Protection Agency shall take such actions under the Clean Air Act [42 U.S.C. 7401 et seq.] as may be appropriate to ensure that such emissions do not exceed 5.60 million tons per year. Such actions may include the promulgation of new and revised standards of performance for new sources, including units subject to section 405(g)(5) of the Clean Air Act, under section 111(b) of the Clean Air Act [42 U.S.C. 7411(b)], as well as promulgation of standards of performance for existing sources, including units subject to section 405(g)(5) of the Clean Air Act, under authority of this section. For an existing source regulated under this section, ‘standard of performance’ means a standard which the Administrator determines is applicable to that source and which reflects the degree of emission reduction achievable through the application of the best system of continuous emission reduction which (taking into consideration the cost of achieving such emission reduction, and any nonair quality health and environmental impact and energy requirements) the Administrator determines has been adequately demonstrated for that category of sources.
Election.—
Regulations promulgated under section 405(b) of the Clean Air Act [42 U.S.C. 7651d(b)] shall not prohibit a source from electing to become an affected unit under section 410 of the Clean Air Act [42 U.S.C. 7651i].”
