Affected: IC 13-15; IC 13-17
Sec. 8.
(a) The bag leak detection system required by the July 1, 2011, edition of 40 CFR 63.548(c)(9) * and section 5 of this rule shall meet the following requirements: (1) The bag leak detection system must be certified by the manufacturer to be capable of detecting particulate matter emissions at concentrations of ten (10) milligrams per actual cubic meter (forty-four ten thousandths (0.0044) grains per actual cubic foot) or less.(2) The bag leak detection system sensor must provide output of relative particulate matter loadings, and the owner or operator must continuously record the output from the bag leak detection system.(3) The bag leak detection system must be equipped with an alarm system that will alert appropriate plant personnel when an increase in relative particulate loadings is detected over a preset level. The alarm must be located where it can be heard by the appropriate plant personnel.(4) Each bag leak detection system that works based on the triboelectric effect must be installed, calibrated, operated, and maintained consistent with the U.S. Environmental Protection Agency guidance document "Fabric Filter Bag Leak Detection Guidance" (EPA-454/R-98-015, September 1997)*. Other bag leak detection systems must be installed, calibrated, and maintained consistent with the manufacturer's written specifications and recommendations.(5) The initial adjustment of the system must, at a minimum, consist of establishing: (A) the baseline output by adjusting the sensitivity (range);(B) the averaging period of the device;(C) the alarm set points; and(D) the alarm delay time.(6) Following initial adjustment, the owner or operator must not adjust the: (A) sensitivity or range;(D) alarm delay time; except as detailed in the maintenance plan required under the July 1, 2011, edition of 40 CFR 63.548(a) *. In no event must the sensitivity be increased by more than one hundred percent (100%) or decreased more than fifty percent (50%) over a three hundred sixty-five (365) day period unless a responsible official certifies the baghouse has been inspected and found to be in good operating condition.
(7) Where multiple detectors are required, the system's instrumentation and alarm may be shared among detectors.(8) For negative pressure, induced air baghouses, and positive pressure baghouses that are discharged to the atmosphere through a stack, the bag leak detector must be installed downstream of the baghouse and upstream of any wet acid gas scrubber.(b) In addition to the record keeping and reporting requirements under the July 1, 2011, edition of 40 CFR 63.550 *, the owner or operator shall comply with the following: (1) Submit a report within thirty (30) days after the end of each preceding six (6) month period ending June 30 and December 31 of each year that includes the following: (A) A description of the actions taken following each bag leak detection system alarm pursuant to the July 1, 2011, edition of 40 CFR 63.548(f)(1) * and 40 CFR 63.548(f)(2) *.(B) Calculations of the percentage of time the alarm on the bag leak detection system was activated during the reporting period.(2) Records for bag leak detection systems shall be maintained on site for a period of three (3) years and be available for an additional two (2) years and shall include the following information:(A) Records of bag leak detection system output.(B) Identification of the date and time of all bag leak detection system alarms.(C) The time that procedures to determine the cause of the alarm were initiated.(D) The cause of the alarm.(E) An explanation of the actions taken.(F) The date and time the alarm was corrected.(G) Records of total operating time of an affected source during smelting operations for each six (6) month period. *These documents are incorporated by reference.
