In accordance
with 5 CFR 1320, the information collection is approved for three
years. The agency is reminded that collections that change the
frequency of collection such as is explained in the supporting
statement, the agency should submit the collection as a revision of
a currently approved collection to OMB.

The National Emission Standards for
Hazardous Air Pollutants (NESHAP) for Primary Aluminum Reduction
Plants (40 CFR Part 63, Subpart LL) were proposed on September 26,
1996, promulgated on October 7, 1997, and most-recently amended on
October 15, 2015. The 2015 amendment includes: 1) polycyclic
organic matter (POM) emission limits for new, existing and
reconstructed prebake potlines; 2) revised POM limits for new,
existing and reconstructed Soderberg potlines; 3) carbonyl sulfide
(COS) emission limits for new, existing and reconstructed potlines;
4) POM emission limits for existing pitch storage tanks; 5)
particulate matter (PM) emission limits for new, existing and
reconstructed potlines, paste production plants and anode bake
furnaces; 6) mercury (Hg) limits for new, existing and
reconstructed anode bake furnaces; 7) arsenic, nickel and
polychlorinated biphenyl (PCB) limits for new, existing and
reconstructed Soderberg potlines; 8) new work practice standards
for anode bake furnaces, paste production plants and potlines; and
9) eliminates the exemptions for periods of startup, shutdown, and
malfunctions (SSM). The amendment also reduces the testing
frequency for total fluoride (TF) from prebake and Soderberg
potlines and POM from Soderberg potlines from monthly to
semiannually. These regulations apply to the following affected
sources at a primary aluminum reduction plant are covered: each new
and existing pitch storage tank, potline, paste production plant
and anode bake furnace that is located at a plant site that is a
major source as defined at §63.2 (except for anode bake furnaces
that are not located on the same site as a primary aluminum
reduction plant). 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 LL. 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. Any owner/operator subject
to the provisions of this part shall maintain a file containing
these documents and retain this file for at least five years
following the generation date of such maintenance reports and
records. All reports are sent to the delegated state or local
authority. In the event that there is no such delegated authority,
the reports are sent directly to the U.S. Environmental Protection
Agency (EPA) regional office.
There is an adjustment decrease
in the total estimated burden as currently identified in the OMB
Inventory of Approved Burdens. This decrease is primarily due to a
program change. The 2015 amendment reduces the frequency of TF
performance tests from monthly to semiannually. This ICR combines
burden from the existing provisions with the burden associated with
the 2015 amendment to the rule, resulting in a net decrease in
burden. Additionally, the total number of affected sources has
decreased as compared to the most recently-approved ICR. There is
an adjustment decrease in the total estimated capital and O&M
costs as compared to the most recently approved ICR. This decrease
occurred because there is a decrease in the total number of
respondents subject to the rule.
On behalf of this Federal agency, I certify that
the collection of information encompassed by this request complies
with 5 CFR 1320.9 and the related provisions of 5 CFR
1320.8(b)(3).
The following is a summary of the topics, regarding
the proposed collection of information, that the certification
covers:
(i) Why the information is being collected;
(ii) Use of information;
(iii) Burden estimate;
(iv) Nature of response (voluntary, required for a
benefit, or mandatory);
(v) Nature and extent of confidentiality; and
(vi) Need to display currently valid OMB control
number;
If you are unable to certify compliance with any of
these provisions, identify the item by leaving the box unchecked
and explain the reason in the Supporting Statement.
