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.

The Administrator concluded, and petitioners concede, that the best system of emission reduction that has been adequately demonstrated for the asphalt concrete industry is represented by a venturi-scrubber with a twenty-inch pressure drop or a baghouse with an air-to-cloth ratio of six-to-one. Indeed, petitioner Warren Brothers informs us that those control technologies can be installed and operated at reasonable cost, and that various asphalt concrete companies are prepared to install those devices on plants that become subject to the final standards of performance.

It is proffered that the asphalt plants do not contribute significantly to air pollution, thereby causing or contributing to the endangerment of public health or welfare. The data upon which the Environmental [p781] Protection Agency has relied in making this determination of the significant contribution is based upon old data no longer applicable and the equipment which is presently available results in no significant endangerment of public health or welfare.
