(a) You must not discharge to the atmosphere visible emissions (VE) from the control device that exceed 5 percent of accumulated occurrences in a 60-minute observation period.
(b) You must not discharge to the atmosphere fugitive PM emissions from the furnace building containing the electrometallurgical operations that exhibit opacity greater than 20 percent (6-minute average), except for one 6-minute average per hour that does not exceed 60 percent.
(a) EAF equipped with fabric filters—(1) Visual monitoring. You must conduct visual monitoring of the monovent or fabric filter outlet stack(s) for any VE according to the schedule specified in paragraphs (a)(1)(i) and (a)(1)(ii) of this section.
(i) Daily visual monitoring. Perform visual determination of fugitive emissions once per day, on each day the process is in operation, during operation of the process.
(ii) Weekly visual monitoring. If no visible fugitive emissions are detected in consecutive daily visual monitoring performed in accordance with paragraph (a)(1)(i) of this section for 90 days of operation of the process, you may decrease the frequency of visual monitoring to once per calendar week of time the process is in operation, during operation of the process. If visible fugitive emissions are detected during these inspections, you must resume daily visual monitoring of that operation during each day that the process is in operation, in accordance with paragraph (a)(1)(i) of this section until you satisfy the criteria of this section to resume conducting weekly visual monitoring.
(2) If the visual monitoring reveals the presence of any VE, you must conduct a Method 22 (appendix A-7 of 40 CFR part 60) test following the requirements of §63.11528(b)(1) within 24 hours of determining the presence of any VE.
(3) If you own or operate an existing affected source, you may install, operate, and maintain a bag leak detection system for each fabric filter as an alternative to the monitoring requirements in paragraph (a)(1) of this section. If you own or operate a new affected source, you must install, operate, and maintain a bag leak detection system for each fabric filter according to the requirements in paragraphs (a)(3)(i) through (a)(3)(vii) of this section. Such source is not subject to the requirements in paragraphs (a)(1) and (a)(2) of this section.
(i) The system must be certified by the manufacturer to be capable of detecting emissions of PM at concentrations of 10 milligrams per actual cubic meter (0.00044 grains per actual cubic foot) or less.
(ii) The bag leak detection system sensor must provide output of relative PM loadings and the owner or operator shall continuously record the output from the bag leak detection system using a strip chart recorder, data logger, or other means.
(iii) The system must be equipped with an alarm that will sound when an increase in relative PM loadings is detected over the alarm set point established in the operation and maintenance plan, and the alarm must be located such that it can be heard, seen, or otherwise detected by the appropriate plant personnel.
(iv) The initial adjustment of the system must, at minimum, consist of establishing the baseline output by adjusting the sensitivity (range) and the averaging period of the device, and establishing the alarm set points. If the system is equipped with an alarm delay time feature, you also must establish a maximum reasonable alarm delay time.
(v) Following the initial adjustment, do not adjust the sensitivity or range, averaging period, alarm set point, or alarm delay time, except that, once per quarter, you may adjust the sensitivity of the bag leak detection system to account for seasonal effects including temperature and humidity.
(vi) For fabric filters that are discharged to the atmosphere through a stack, the bag leak detector sensor must be installed downstream of the fabric filter and upstream of any wet scrubber.
(4) When operating a bag leak detection system, if an alarm sounds, conduct visual monitoring of the monovent or fabric filter outlet stack(s) as required in paragraph (a)(1) of this section within 1 hour. If the visual monitoring reveals the presence of any VE, you must conduct a Method 22 test following the requirements of §63.11528(b)(1) within 24 hours of determining the presence of any VE.
(5) You must prepare a site-specific monitoring plan for each bag leak detection system. You must operate and maintain each bag leak detection system according to the plan at all times. Each plan must address all of the items identified in paragraphs (a)(5)(i) through (a)(5)(v)of this section.
(ii) Initial and periodic adjustment of the bag leak detection system including how the alarm set-point and alarm delay time will be established.
(b) EAF equipped with wet scrubbers—(1) Visual monitoring. You must conduct visual monitoring of the wet scrubber outlet stack(s) for any VE according to the schedule specified in paragraphs (b)(1)(i) and (b)(1)(ii) of this section.
(ii) Weekly visual monitoring. If no visible fugitive emissions are detected in consecutive daily visual monitoring performed in accordance with paragraph (b)(1)(i) of this section for 90 days of operation of the process, you may decrease the frequency of visual monitoring to once per calendar week of time the process is in operation, during operation of the process. If visible fugitive emissions are detected during these inspections, you must resume daily visual monitoring of that operation during each day that the process is in operation, in accordance with paragraph (b)(1)(i) of this section until you satisfy the criteria of this section to resume conducting weekly visual monitoring.
(3) If you own or operate an existing affected source, you may install, operate and maintain a continuous parameter monitoring system (CPMS) to measure and record the 3-hour average pressure drop and scrubber water flow rate as an alternative to the monitoring requirements specified in paragraph (b)(1) of this section. If you own or operate a new sealed EAF affected source, you must install, operate, and maintain a CPMS for each wet scrubber. Such source is not subject to the requirements in paragraph (b)(1) of this section.
(4) When operating a CPMS, if the 3-hour average pressure drop or scrubber water flow rate is below the minimum levels that indicate normal operation of the control device, conduct visual monitoring of the outlet stack(s) as required by paragraph (b)(1) of this section within 1 hour of determining that the 3-hour average parameter value is below the required minimum levels. Manufacturer's specifications for pressure drop and liquid flow rate will be used to determine normal operations. If the visual monitoring reveals the presence of any VE, you must conduct a Method 22 (appendix A-7 of 40 CFR part 60) test following the requirements of §63.11528(b)(1) within 24 hours of determining the presence of any VE.
Bag leak detection system means a system that is capable of continuously monitoring relative PM (i.e., dust) loadings in the exhaust of a fabric filter to detect bag leaks and other upset conditions. A bag leak detection system includes, but is not limited to, an instrument that operates on triboelectric, electrodynamic, light scattering, or other effect to monitor relative PM loadings continuously.
Charging means introducing materials to an EAF or other reaction vessel, which may consist of, but are not limited to, ores, slag, carbonaceous material, and/or limestone.
Control device means the air pollution control equipment used to remove PM from the effluent gas stream generated by an EAF furnace or other reaction vessel.
Electric arc furnace means any furnace wherein electrical energy is converted to heat energy by transmission of current between electrodes partially submerged in the furnace charge.
Electrometallurgical operations means the use of electric and electrolytic processes to purify metals or reduce metallic compounds to metals.
Fugitive emissions means any pollutant released to the atmosphere that is not discharged through a ventilation system that is specifically designed to capture pollutants at the source, convey them through ductwork, and exhausts them from a control device. Fugitive emissions include pollutants released to the atmosphere through windows, doors, vents, or other building openings. Fugitive emissions also include pollutants released to the atmosphere through other general building ventilation or exhaust systems not specifically designed to capture pollutants at the source.
Sealed EAF means a furnace equipped with the cover with seals around the electrodes and outer edges of the cover to eliminate air being drawn in under the cover.
Tapping means the removal of product from the EAF or other reaction vessel under normal operating conditions, such as removal of metal under normal pressure and movement by gravity down the spout into the ladle.
