A bill to provide that major stationary sources complying with all applicable emission limitations and standards of performance established pursuant to the Clean Air Act shall not be subject to any more stringent limitations or standards for a period of ten years.

Amends the Clean Air Act to prohibit, for ten-years, the application of a more stringent emission limitation or standard of performance to: (1) any existing major stationary source which comes into compliance with all emission limitations in the applicable implementation plan; or (2) any new or modified major stationary source the construction or modification of which meets all applicable emission limitations and standards of performance. Sets such ten-year period to run from the date of completion of compliance, construction, or modification, or during the period of depreciation or amortization of such facility (for Internal Revenue Code purposes), whichever period ends first.

Exempts from the application of this Act any source to which a substantial imminent threat to public health can be attributed, as determined by the Administrator of the Environmental Protection Agency.
