    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.
