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 a decrease in burden
from the most-recently approved ICR as currently identified in the
OMB Inventory of Approved Burdens. This increase is not due to any
program changes. The adjustment decrease in burden from the
most-recently approved ICR is due to a decrease in the number of
sources. The currently approved ICR assumed 11 respondents.
Consultations with the Aluminum Association conducted during the
renewal of this ICR revealed that there are only eight primary
aluminum reduction plants currently subject to this subpart. This
decrease in the number of respondents has resulted in a decrease in
respondent labor hours. This ICR adjusts the capital cost from the
previously-approved ICR to reflect costs from the October 15, 2015
rule, which were annualized over a 15 year period; the previous ICR
assumed that all capital costs were completed within the first
three years of the 2015 final rule. This ICR also adjusts the
operation and maintenance (O&M) costs from the previous ICR
from 1997 dollars to 2019 dollars using the CEPCI CE Index, and
includes O&M costs for annual monitoring from the 2015 final
rule that were inadvertently excluded from the previous ICR.
Therefore, this ICR reflects a modest increase in capital and
O&M costs from the most-recently approved ICR. This ICR also
corrects the total number of responses to reflect the submittal of
performance test reports on a semiannual basis, which were
inadvertently excluded from the previous ICR. This ICR uses labor
rates from the most-recent Bureau of Labor Statistics report (March
2020) to calculate respondent burden costs. This ICR, by in large,
reflects the on-going burden and costs for existing facilities.
Activities for existing sources include annual and semiannual
performance tests, continuous monitoring of pollutants, and the
submission of semiannual reports.
