The National Emission Standards for
Hazardous Air Pollutants (NESHAP) for the regulations published at
40 CFR Part 63, Subpart IIIII were proposed on July 3, 2002, and
promulgated on December 19, 2003. These regulations apply to
existing facilities and new facilities that are mercury cell
chlor-alkali plants part of a major source of hazardous air
pollutant (HAP) emissions or part of an area source of HAP
emissions. A major source of HAP is one that has the potential to
emit 10 tons or more of any HAP or 25 tons or more of total HAP per
year; an area source is one with a potential to emit less than
this. New facilities include those that commenced construction,
modification or reconstruction after the date of proposal. This
information is being collected to assure compliance with 40 CFR
Part 63, Subpart IIIII. 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.
There is a decrease in burden
from the most-recently approved ICR as currently identified in the
OMB Inventory of Approved Burdens. This is due to a decrease in the
number of sources subject to the rule. Data gathered by EPA in the
development of the proposed Residual Risk and Technology Review for
40 CFR Part 63, Subpart IIIII (86 FR 1362, January 8, 2021)
indicates that there is only one source subject to this rule. The
regulations have been revised in the past three years to add
electronic reporting requirements, but it is assumed that there is
no additional burden associated with the requirements, which
consist of an upload of a currently required notification in
portable document format (PDF). There is no change in
capital/startup costs, as there is no change in the number of new
facilities, which remains at zero. Due to the decrease in the
number of facilities subject to the rule, total O&M costs have
decreased from the previous ICR.
