The National Emission Standards for
Hazardous Air Pollutants (NESHAP) for Primary Magnesium Refining
was originally proposed on January 22, 2003, originally promulgated
on October 10, 2003, and amended on April 20, 2006. The NESHAP is
codified at 40 CFR part 63, subpart TTTTT. Amendments to the NESHAP
are being proposed as a result of the residual risk and technology
review (RTR) required under the Clean Air Act (CAA) (as discussed
further below). The NESHAP applies to existing and new facilities
that perform primary magnesium refining where the total hazardous
air pollutants (HAP) emitted are greater than, or equal to, 10 tons
per year for each HAP, or where the total HAP emitted are greater
than, or equal to, 25 tons per year of any combination of HAP. 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
TTTTT. In general, all NESHAP standards require initial
notifications, performance tests, and periodic reports by the
owners/operators of the affected facilities. Owners/operators 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 under the rule.
The proposed RTR amendments to
the NESHAP for Primary Magnesium Refining (40 CFR, part 63, subpart
TTTTT) (1) revise provisions in the NESHAP (40 CFR part 63, subpart
TTTTT) to remove the SSM exemption and SSM plan requirement; (2)
add a work practice standard for malfunction events associated with
the CRB; (3) add a MACT emissions standard for the CBS; (4) add the
requirement to continuously measure pH for all control devices; (5)
add electronic reporting requirements for test reports and (6) make
technical and editorial changes. Where applicable, adjustments for
these proposed RTR amendments are reflected in Tables 1 and 2 of
this ICR. The burden estimated for an affected facility to
familiarize themself with regulatory requirements remained
unchanged since the one affected facility is already complying with
the rule, and therefore is aware of current rule requirements. The
current burden estimate is expected to cover review of the actual
time it would take industry to review the proposed amendments.
Burden estimates were added for the facility to meet the
requirement to record the corrective measures taken when the CRB
malfunctions, record control device operating parameters, prepare
notifications of performance test/performance evaluation, report
the results of the performance tests through the ERT, prepare
notification of compliance status, record failures to meet
standards and actions taken to minimize emissions, conduct
refresher training, transition to submitting notifications and
semiannual reports through CEDRI, and compile data for semiannual
reports. Burden estimates were removed for developing SSM plans and
submitting periodic SSM reports.
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;
