ABSTRACT
Environmental regulation of the fertilizer industry had its inception with the Clean Air Amendments of 1970, PL 91-604. Environmental Protection Agency to publish within 30 days after their enactment proposed regulations prescribing a national primary ambient air quality standard and a national secondary ambient air standard for each air pollutant for which air quality criteria has been issued prior to such date of enactment. Since fluoride emissions are considered to be welfare-related rather than health-related, Subpart B allows a state to apply less stringent requirements for the existing regulated facility. The control of particulate emissions is governed by a number of regulatory standards such as the National Ambient Air Standards, New Source Performance Standards, Prevention of Significant Deterioration Regulations, designation of nonattainment areas, and, of course, state and local regulations. Associated with most integrated fertilizer plant complexes are sulfuric acid plants, which are also subject to regulation.
