ENVIRONMENTAL PROTECTION AGENCY

[EPA-HQ-OAR-2021-0120; FRL--9938-01-OMS]


Information Collection Request Submitted to OMB for Review and 
Approval; Comment Request; NESHAP for Primary Magnesium Refining 
(Renewal)

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: The Environmental Protection Agency has submitted an 
information collection request (ICR), NESHAP for Primary Magnesium 
Refining (EPA ICR Number 2098.10, OMB Control Number 2060-0536), to the 
Office of Management and Budget (OMB) for review and approval in 
accordance with the Paperwork Reduction Act. This is a proposed 
extension of the ICR, which is currently approved through June 30, 
2022. Public comments were previously requested, via the Federal 
Register, on April 13, 2021 during a 60-day comment period. This notice 
allows for an additional 30 days for public comments. A fuller 
description of the ICR is given below, including its estimated burden 
and cost to the public. An agency may neither conduct nor sponsor, and 
a person is not required to respond to, a collection of information 
unless it displays a currently valid OMB control number.

DATES: Additional comments may be submitted on or before July 15, 2022.

ADDRESSES: Submit your comments, referencing Docket ID Number EPA-HQ-
OAR-2021-0120, to EPA online using https://www.regulations.gov/ (our 
preferred method), or by email to [email protected], or by mail to: 
EPA Docket Center, Environmental Protection Agency, Mail Code 28221T, 
1200 Pennsylvania Ave. NW, Washington, DC 20460. EPA's policy is that 
all comments received will be included in the public docket without 
change including any personal information provided, unless the comment 
includes profanity, threats, information claimed to be Confidential 
Business Information (CBI), or other information whose disclosure is 
restricted by statute.
    Submit written comments and recommendations to OMB for the proposed 
information collection within 30 days of publication of this notice to 
www.reginfo.gov/public/do/PRAMain. Find this particular information 
collection by selecting ``Currently under 30-day Review--Open for 
Public Comments'' or by using the search function.

    Abstract: The National Emission Standards for Hazardous Air 
Pollutants (NESHAP) for Primary Magnesium Refining (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 
either 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

[[Page 36123]]

compliance, and are required of all affected facilities subject to the 
NESHAP.
    Form Numbers: None.
    Respondents/affected entities: Primary magnesium refining 
facilities.
    Respondent's obligation to respond: Mandatory 40 CFR 63, Subpart 
TTTTT.
    Estimated number of respondents: One (total).
    Frequency of response: Semiannually.
    Total estimated burden: 972 hours (per year). Burden is defined at 
5 CFR 1320.3(b).
    Total estimated cost: $116,000 (per year), which includes $1,200 in 
annualized capital/startup and/or operation & maintenance costs.
    Changes in the Estimates: 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.
