The National Emission Standards for Hazardous Air Pollutants (NESHAP) for the regulations published at 40 CFR Part 63, Subpart TTTTT were proposed on January 22, 2003, promulgated on October 10, 2003, and amended on April 20, 2006. These regulations apply to existing and new facilities that perform primary magnesium refining where the total hazardous air pollutants (HAPs) emitted are greater than, or equal to, 10 tons per year for each HAP, or where the total HAPs emitted are greater than, or equal to, 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 TTTTT. 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 an adjustment increase in the total estimated burden as currently identified in the OMB Inventory of Approved Burdens. This increase is not due to any program changes. The burden in this ICR has been adjusted to account for more accurate estimates for performance testing costs based on consultations with industry. The previous ICR assumed that a single performance test was conducted once every three years by the affected facility. This ICR adjusts the performance testing costs to reflect that the facility conducts separate performance tests for individual units during the term of the ICR. The regulation, 40 CFR 63.9912, requires performance testing no less frequently than twice (at mid-term and renewal) of each term of the Title V permit, or every 2.5 years, for each emission point. For the facility subject to this rule, we have clarified that multiple emission points must be tested twice during the Title V permit term, with approximately 20 percent of units anticipated to require a retest. This ICR therefore assumes that performance tests are conducted for approximately two emission units in each year during the three-year period of this ICR. Therefore, labor costs have been adjusted to account for submission of notification and reports for performance tests twice annually. This change also results in an increase in the number of responses.
