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.
