National Asphalt Pavement Association v…
(1976)
“ We also find a fundamental flaw in the contention that once an industry complies with regulations designed to reduce air pollution to the level established by national primary and secondary air quality standards, it is no longer a "significant contributor" subject to new source regulation. Compliance with existing regulations may well enable the states to achieve the national standards, but it does not mean that the Administrator is precluded from exercising regulatory authority to prevent deterioration of clean areas. ”
