NESHAP for Lime Manufacturing (40 CFR Part 63, Subpart AAAAA) (Final Rule)

The National Emission Standards for Hazardous Air Pollutants (NESHAP) for Lime Manufacturing (40 CR Part 63, Subpart AAAAA) were proposed on December 20, 2002, promulgated on January 5, 2004, and amended on April 20, 2006. These regulations apply to existing facilities and new major source facilities that either emit or have the potential to emit any single hazardous air pollutant (HAP) at a rate of 10 tons (9.07 megagrams) or more per year or any combination of HAP at a rate of 25 tons (22.68 megagrams) or more per year from all emission sources at the plant site. This subpart covers lime kilns, their associated coolers, and processed stone handling (PSH) operation systems located at a lime manufacturing plant that is a major source. New facilities include those that commenced construction, modification or reconstruction after the date of proposal. This information is being collected to assure compliance with 40 CFR Part 63, Subpart AAAAA. This ICR is prepared for final rule amendments to the NESHAP for Lime Manufacturing Plants (40 CFR part 63, subpart AAAAA). 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.
