These regulations apply to owner or operator of the affected facilities, which include new or existing potlines, paste production plants, or anode bake furnaces associated with primary aluminum production and located at a major source, and for each new pitch storage tank associated with a primary aluminum reduction plant. New facilities include those that commenced either construction or reconstruction after the date of proposal. This information is being collected to assure compliance with 40 CFR Part 63, Subpart LL. 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.
