The New Source Performance Standards (NSPS) for Nitric Acid Plants (40 CFR Part 60, Subpart G) were proposed on August 17, 1971, promulgated on June 14, 1974, and amended on August 14, 2012. The NSPS for Nitric Acid Plants (40 CFR Part 60, Subpart Ga) were proposed on October 14, 2011, promulgated on August 14, 2012, and were amended on May 6, 2014 in order to correct a minor error. Subpart G applies to nitric acid production units, producing weak (30 to 70 percent) nitric acid, which commenced construction, modification or reconstruction either on or after August 17, 1971 and prior to October 14, 2011. Subpart G limits the emissions of nitrogen oxides, expressed as nitrogen dioxide (NO2), to 1.5 kilograms per metric ton of acid produced (3.0 lb. per ton), and limits opacity to 10 percent. Subpart Ga applies to nitric acid production units, producing weak (30 to 70 percent) nitric acid, for which construction, reconstruction, or modification commenced after October 14, 2011, and limits nitrogen oxides (expressed as NO2) to 0.50 lb per ton of 100 percent nitric acid produced. This information is being collected to assure compliance with 40 CFR Part 60, Subparts G and Ga.
In general, all NSPS 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 NSPS.
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 change in the cost estimates is due to adjustments for growth in the industry. There is an increase in the labor hours and operation and maintenance costs due to an increase in the number of respondents subject to subpart Ga from 5 to 8 based on growth. There is also a nominal increase in the number of responses (0.3 responses per year), as this ICR assumes ten percent of the 3 new respondents under subpart Ga could submit a report of noncompliance with the NOx emission standard; however, this increase does not significantly change the number of annual responses from the prior ICR.
