The National Emission Standards for Hazardous Air Pollutants (NESHAP) for the regulations published at 40 CFR Part 63, Subpart IIIII were proposed on July 3, 2002, and promulgated on December 19, 2003. These regulations apply to existing facilities and new facilities that are mercury cell chlor-alkali plants part of a major source of hazardous air pollutant (HAP) emissions or part of an area source of HAP emissions. A major source of HAP is one that has the potential to emit 10 tons or more of any HAP or 25 tons or more of total HAP per year; an area source is one with a potential to emit less than this. 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 IIIII.
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.
There is a decrease in burden from the most-recently approved ICR as currently identified in the OMB Inventory of Approved Burdens. This is due to a decrease in the number of sources subject to the rule. Data gathered by EPA in the development of the proposed Residual Risk and Technology Review for 40 CFR Part 63, Subpart IIIII (86 FR 1362, January 8, 2021) indicates that there is only one source subject to this rule. The regulations have been revised in the past three years to add electronic reporting requirements, but it is assumed that there is no additional burden associated with the requirements, which consist of an upload of a currently required notification in portable document format (PDF). There is no change in capital/startup costs, as there is no change in the number of new facilities, which remains at zero. Due to the decrease in the number of facilities subject to the rule, total O&M costs have decreased from the previous ICR.
