NESHAP for Plating and Polishing Area Sources (40 CFR part 63, subpart WWWWWW) (Renewal)

The National Emission Standards for Hazardous Air Pollutants (NESHAP) for Plating and Polishing Area Sources (40 CFR Part 63, Subpart WWWWWW) apply to both existing and new plating and polishing facilities that are an area source of hazardous air pollutant (HAP) emissions and that use one or more of the following metal HAP: cadmium, chromium, lead manganese, or nickel (hereafter referred to as the plating and polishing metal HAP). A plating and polishing facility is a plant site that is engaged in any of the following processes: non-chromium electroplating; electroless or non-electrolytic plating; other non-electrolytic metal coating processes such as chromate conversion coating, nickel acetate sealing, sodium dichromate sealing, and manganese phosphate coating, and thermal spraying; dry mechanical polishing of finished metals and formed products after plating or thermal spraying; electroforming; and electro-polishing. New facilities include those that commenced construction, modification ,or reconstruction after the date of proposal. 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 with 40 CFR Part 63, Subpart WWWWWW.
