NESHAP for Chemical Preparations Industry (40 CFR part 63, subpart BBBBBBB) (Renewal)

The National Emission Standards for Hazardous Air Pollutants (NESHAP) for Chemical Preparations Industry (40 CFR 63, Subpart BBBBBBB) were proposed on August 5, 2009, and promulgated on December 30, 2009. These regulations apply to both existing and new chemical preparation facilities that conduct the mixing, milling, blending or extruding of industrial chemicals and that are area sources of hazardous air pollutants (HAPs). Area sources are classified as sources that emit less than 10 tons per year of a single HAP or less than 25 tons per year of any combination of HAPs. New facilities include those that commenced construction or reconstruction after the date of proposal. This information is being collected to assure compliance with 40 CFR Part 63, Subpart BBBBBBB. In general, all NESHAP standards require initial notifications, performance tests, and periodic reports by the owners/operators of the affected facilities. They are also required to maintain records of the occurrence and duration of any startup, shutdown, or malfunction in the operation of an affected facility, or any period during which the monitoring system is inoperative. These notifications, reports, and records are essential in determining compliance, and are required of all affected facilities subject to NESHAP.
