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).
