# ACTION:

Notice.

# SUMMARY:

*Abstract:*                     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.                

*Form Numbers:*                     None.                

*Respondents/affected entities:*                     Nitric acid plants.                

*Respondent's obligation to respond:*                     Mandatory (40 CFR part 60, subparts G and Ga).                

*Estimated number of respondents:*                     35 (total).                

*Frequency of response:*                     Initially, occasionally, and semiannually.                

*Total estimated burden:*                     2,840 hours (per year). Burden is defined at 5 CFR 1320.3(b).                

*Total estimated cost:*                     $4,690,000 (per year), which includes $4,330,000 in annualized capital/startup and/or operation & maintenance costs.                

*Changes in the Estimates:*                     The increase in burden from the most-recently approved ICR is due to an adjustment(s). The adjustment increase in burden from the most-recently approved ICR is not due to any program changes, but due to an increase in the number of new sources. Capital/startup and operation and maintenance costs have also increased due to the increase in the number of new or modified sources and an adjustment to update costs to 2022 $ using the CEPCI Equipment Cost Index.
