The National Emission Standards for
Hazardous Air Pollutants (NESHAP) for Hydrochloric Acid Production
were proposed on September 18, 2001 (66 FR 48174), promulgated on
April 17, 2003 (68 FR 19076), and amended on April 7, 2006 (71 FR
17738). Amendments to the NESHAP are being promulgated as a result
of the residual risk and technology review (RTR) required under the
Clean Air Act (CAA) (as discussed further below). The NESHAP apply
to hydrochloric acid production facilities that emit greater than
or equal to 10 tons per year (tpy) of any one hazardous air
pollutant (HAP) or greater than or equal to 25 tpy of any
combination of HAP. Affected sources include new and existing
hydrochloric acid production facilities. The pollutants regulated
are hydrochloric acid (HCl) and chlorine (Cl2). New facilities
include those that commenced construction or reconstruction after
the date of the original proposal (September 18, 2001). This
information is being collected to assure compliance with 40 CFR
Part 63, Subpart NNNNN. 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
failures to meet applicable standards, 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. A semiannual
report is also required. As part of the residual risk and
technology review (RTR) for the NESHAP, the EPA is finalizing
amendments to remove the startup, shutdown, and malfunction (SSM)
exemption; remove the SSM plan and associated periodic report
requirements; add a work practice standard for maintenance vents
used during startup and shutdown; require electronic submittal of
the notification of compliance status, results of performance
evaluations of continuous monitoring systems, compliance reports,
and performance test results; and make miscellaneous technical and
editorial changes. The remaining portions of the NESHAP remain
unchanged.
This ICR is prepared for
amendments to the NESHAP for Hydrochloric Acid Production (40 CFR,
Part 63, Subpart NNNNN). These amendments: (1) adjust references to
the Part 63 General Provisions (40 CFR, Part 63, Subpart A) and
revise provisions in the NESHAP (40 CFR Part 63, Subpart NNNNN) to
remove the SSM exemption and SSM plan and periodic report
requirements; (2) require electronic submittal of performance test
results; and (3) make technical and editorial changes. The number
of facilities subject to the standards changed based on
consultation with industry representatives, review of EPAs ECHO
database, and review of title V permits. Consolidation within the
industry reduced the number of affected facilities to nineteen that
are currently subject to the standards. In addition, the burden
estimate for reading and understanding the rule requirements was
adjusted to reflect the time it would take industry to review the
amended rule, including becoming familiar with the new requirement
to electronically submit performance test results. Burden estimates
were reduced for submitting periodic SSM reports after consultation
with industry representatives. The previous estimate of SSM
frequency was roughly an order of magnitude higher than the actual
frequency, according to industry. The burden estimate for
performance test report submittal was not adjusted to account for
the new requirement that results of performance tests will be
reported electronically through CEDRI using the ERT. The burden
estimate of four hours in the current ICR for paper format
submittal of performance test results is an appropriate estimate
for electronic submittal of performance test results.
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 proposed collection of information, that the certification
covers:
(i) Why the information is being collected;
(ii) Use of information;
