Epa Guidance On Neshaps Revision Of Initial List Of Categories Ofsources And Schedule For Standards Under Sections 112(c) And (e) Ofrnthe Clean Air Act Amendments Of 1990

摘要

The Clean Air Act Amendments of 1990 [ Pub. L. 101-549] require, under the revisions to Section 112, that the Agency list and promulgate national emission standards for hazardous air pollutants (NESHAP) in order to control, reduce, or otherwise limit the emissions of HAP from categories of major and area sources. Pursuant to the various specific listing requirements in Section 112(c), the Agency published on July 16, 1992 (57 FR 31576) an initial list of 174 categories of major and area sources that would be henceforth subject to emission standards. Following this listing, pursuant to requirements in Section 112(e), on December 3, 1993 (58 FR 63941) the Agency published a schedule for the promulgation of emission standards for each of the 174 listed source categories. The reader is directed to these two notices for information relating to development of the initial list and schedule.rnThere have been specific notices since the initial list and schedule that have revised the list and schedule in the context of actions relating to individual source categories. For example, on November 12, 1993 (58 FR 60021), the Agency listed marine vessel loading operations as a category of major sources, with standards to be promulgated, pursuant to Section 112(c)(5), by the year 2000. As another example, on September 8, 1994 (59 FR 46339), the Agency promulgated standards for HAP emissions for industrialrnprocess cooling towers. This latter action did not revise the list or schedule, per se, but specifically delineated rule applicability by defining the affected sources within the listed category.
