(3) Agglomerating furnace emission vents. (c) If the owner or operator of a secondary lead smelter uses baghouses equipped with HEPA filters as a secondary filter used to control emissions from any source subject to the lead emission standards in sections 3 through 5 of this rule, the owner or operator of secondary lead smelter must monitor and record the pressure drop across each HEPA filter system daily as follows: (1) If the pressure drop is outside the limit specified by the filter manufacturer, the owner or operator of a secondary lead smelter shall take the appropriate corrective measures, including, but not limited to, the following: (A) Inspecting the filter and filter housing for air leaks and torn or broken filters. (B) Replacing defective filter media, or otherwise repairing the control device. (C) Sealing off a defective control device by routing air to other control devices. (D) Shutting down the process producing the particulate emissions. (2) The owner or operator of a secondary lead smelter shall maintain purchasing records and manufacturer's specifications of any HEPA filters installed on process fugitive emissions and fugitive dust stacks demonstrating the filters have been certified by the manufacturer to remove ninety-nine and ninety-seven hundredths percent (99.97%) of all particles three-tenths (0.3) micrometers and larger. The records and manufacturer's specifications shall be: (A) maintained on site for three (3) years; and (B) available for an additional two (2) years. (d) If the owner or operator of a secondary lead smelter uses a wet scrubber to control particulate matter and metal hazardous air pollutant emissions from a process vent to demonstrate continuous compliance with the emission standards, the owner or operator of a secondary lead smelter must monitor and record the pressure drop and water flow rate of the wet scrubber during the initial performance or compliance test conducted to demonstrate compliance with the applicable lead emission limits under sections 3 through 5 of this rule. Thereafter, the owner or operator of a secondary lead smelter shall: (1) monitor and record the pressure drop and water flow rate values at least once every hour; and (2) maintain the pressure drop and water flow rate at levels no lower than thirty percent (30%) below the pressure drop and water flow rate measured during the initial performance or compliance test. (e) The owner or operator of a secondary lead smelter shall demonstrate continuous compliance with the total hydrocarbon and dioxin and furan emission standards. During periods of startup and shutdown, the requirements of subdivision (4) do not apply. Instead, the owner or operator of a secondary lead smelter shall demonstrate compliance with the standard for total hydrocarbon by meeting the requirements of section 5(i) of this rule. The requirements to demonstrate continuous compliance are as follows: (1) The owner or operator of a secondary lead smelter shall install, calibrate, maintain, and continuously operate a device to monitor and record the temperature of the afterburner or furnace exhaust streams consistent with the requirements for continuous monitoring systems in the July 1, 2012, edition of 40 CFR 63.8*. (2) Prior to or in conjunction with the initial performance or compliance test to determine compliance with section 5(d) of this rule, the owner or operator of a secondary lead smelter shall conduct a performance evaluation for the temperature monitoring device according to the July 1, 2012, edition of 40 CFR 63.8(e)*. The definitions, installation specifications, test procedures, and data reduction procedures for determining calibration drift, relative accuracy, and reporting described in Performance Specification 2, 40 CFR 60, Appendix B, sections 2*, 3*, 5*, 7*, 8*, 9*, and 10* must be used to conduct the evaluation. The temperature monitoring device must meet the following performance and equipment specifications: (A) The recorder response range must include zero (0) and one and one-half (1.5) times the average temperature identified in subdivision (3). (B) The monitoring system calibration drift must not exceed two percent (2%) of one and one-half (1.5) times the average temperature identified in subdivision (3). (C) The monitoring system relative accuracy must not exceed twenty percent (20%). (D) The reference method must be a National Institute of Standards and Technology calibrated reference thermocouple-potentiometer system or an alternate reference method, subject to the approval of U.S. EPA. (3) The owner or operator of a secondary lead smelter shall monitor and record the temperature of the afterburner or the furnace exhaust streams every fifteen (15) minutes during the initial performance or compliance test for total hydrocarbons and dioxins and furans and determine an arithmetic average for the recorded temperature measurements. (4) To demonstrate continuous compliance with the standards for total hydrocarbons and dioxins and furans, the owner or operator of a secondary lead smelter shall maintain an afterburner or exhaust temperature so that the average temperature in any three (3) hour period does not fall more than twenty-eight (28) degrees Celsius below the average established in subdivision (3). (f) The owner or operator of a new emission unit subject to the requirements under sections 3 through 5 of this rule shall install, calibrate, maintain, and operate a CEMS for measuring lead emissions. In addition to the requirements for CEMS in the July 1, 2012, edition of 40 CFR 63.8(c) that are referenced in section 1(d) of this rule, the owner or operator of a secondary lead smelter shall comply with the requirements for CEMS specified in subsection (g) and the following requirements: (1) The owner or operator of a new emission unit subject to the emission limits for lead compounds under sections 3 through 5 of this rule shall install a CEMS for measuring lead emissions within one hundred eighty (180) days of promulgation by U.S. EPA of performance specifications for lead CEMS. (2) Prior to one hundred eighty (180) days after U.S. EPA promulgates performance specifications for CEMS used to measure lead concentrations, the owner or operator of a secondary lead smelter shall use the procedure described in section 11(a)(1) of this rule to determine compliance. (3) Vents from control devices that serve only to control emissions from buildings containing lead-bearing materials are exempt from the requirement to install a CEMS for measuring lead emissions. (g) If a CEMS is used to measure lead emissions, the owner or operator of a secondary lead smelter shall install a CEMS with a sensor in a location that provides representative measurement of the exhaust gas flow rate at the sampling location of the CEMS used to measure lead emissions, taking into account the manufacturer's recommendations. The flow rate sensor is that portion of the system that senses the volumetric flow rate and generates an output proportional to that flow rate. The owner or operator of a secondary lead smelter shall comply with the following requirements: (1) The CEMS shall be designed to measure the exhaust gas flow rate over a range that extends from a value of at least twenty percent (20%) less than the lowest expected exhaust flow rate to a value of at least twenty percent (20%) greater than the highest expected exhaust gas flow rate. (2) The CEMS shall be equipped with a data acquisition and recording system that is capable of recording values over the entire range specified in subdivision (1). (3) The owner or operator of a secondary lead smelter shall perform an initial relative accuracy test of the CEMS in accordance with the applicable performance specification in 40 CFR 60, Appendix B*. (4) The owner or operator of a secondary lead smelter shall operate the CEMS and record data during all periods of operation of the affected emission unit including periods of startup, shutdown, and malfunction, except for periods of monitoring system malfunctions, repairs associated with monitoring system malfunctions, and required monitoring system quality assurance or quality control activities including, as applicable, calibration checks and required zero and span adjustments. (5) If the owner or operator of a secondary lead smelter uses a CEMS to measure lead emissions, the owner or operator of a secondary lead smelter shall calculate the average lead concentration and flow rate monthly to determine compliance with sections 3 through 5 of this rule. (6) When the CEMS is unable to provide quality assured data, the following requirements apply: (A) When data are not available for periods of up to forty-eight (48) hours, the highest recorded hourly emissions rate from the previous twenty-four (24) hours shall be used. (B) When data are not available for forty-eight (48) or more hours, the maximum daily emissions rate based on the previous thirty (30) days shall be used. *These documents are incorporated by reference.
