【正文】 (e)(1) and the conditions specified in paragraphs (b) through (i) of this section.(b) To determine pliance with the applicable emissions limit for PM in 167。(a)(7) for your iron and steel foundry no less frequently than once every 6 months.[69 FR 21923, Apr. 22, 2004, as amended at 73 FR 7219, Feb. 7, 2008]167。When must I conduct subsequent performance tests?(a) You must conduct subsequent performance tests to demonstrate pliance with all applicable PM or total metal HAP, VOHAP, and TEA emissions limitations in 167。(a)(2)(ix).(d) If you menced construction or reconstruction between December 23, 2002 and April 22, 2004, and you chose to ply with the proposed emissions limit when demonstrating initial pliance, you must conduct a second performance test to demonstrate pliance with the promulgated emissions limit by October 19, 2007 or after startup of the source, whichever is later, according to 167。 that applies to you where initial pliance is not demonstrated using a performance test, you must demonstrate initial pliance no later than 30 calendar days after the pliance date that is specified for your iron and steel foundry in 167。 that applies to you.(b) For each work practice standard in 167。(a)(2), you must conduct a performance test no later than 180 calendar days after the pliance date that is specified in 167。(e)(3). The startup, shutdown, and malfunction plan also must specify what constitutes a shutdown of a cupola and how to determine that operating conditions are normal following startup of a cupola.[69 FR 21923, Apr. 22, 2004, as amended at 71 FR 20468, Apr. 20, 2006]Initial Compliance Requirements167。What are my general requirements for plying with this subpart?(a) You must be in pliance with the emissions limitations, work practice standards, and operation and maintenance requirements in this subpart at all times, except during periods of startup, shutdown, or malfunction.(b) During the period between the pliance date specified for your iron and steel foundry in 167。s instructions for routine and longterm maintenance.(4) A sitespecific monitoring plan for each bag leak detection system. For each bag leak detection system that operates on the triboelectric effect, the monitoring plan must be consistent with the remendations contained in the . Environmental Protection Agency guidance document “Fabric Filter Bag Leak Detection Guidance” (EPA–454/R–98–015). This baghouse monitoring plan is subject to approval by the Administrator. The owner or operator shall operate and maintain the bag leak detection system according to the sitespecific monitoring plan at all times. The plan must address all of the items identified in paragraphs (b)(4)(i) through (v) of this section.(i) Installation of the bag leak detection system.(ii) Initial and periodic adjustment of the bag leak detection system including how the alarm setpoint will be established.(iii) Operation of the bag leak detection system including quality assurance procedures.(iv) How the bag leak detection system will be maintained including a routine maintenance schedule and spare parts inventory list.(v) How the bag leak detection system output will be recorded and stored.(5) Corrective action plan for each baghouse. The plan must include the requirement that, in the event a bag leak detection system alarm is triggered, you must initiate corrective action to determine the cause of the alarm within 1 hour of the alarm, initiate corrective action to correct the cause of the problem within 24 hours of the alarm, and plete the corrective action as soon as practicable. Corrective actions taken may include, but are not limited to:(i) Inspecting the baghouse for air leaks, torn or broken bags or filter media, or any other condition that may cause an increase in emissions.(ii) Sealing off defective bags or filter media.(iii) Replacing defective bags or filter media or otherwise repairing the control device.(iv) Sealing off a defective baghouse partment.(v) Cleaning the bag leak detection system probe or otherwise repairing the bag leak detection system.(vi) Making process changes.(vii) Shutting down the process producing the PM emissions.(6) Procedures for providing an ignition source to mold vents of sand mold systems in each pouring area and pouring station unless you determine the mold vent gases either are not ignitable, ignite automatically, or cannot be ignited due to accessibility or safety issues. You must document and maintain records of this determination. The determination of ignitability, accessibility, and safety may enpass multiple casting patterns provided the castings utilize similar sandtometal ratios, binder formulations, and coating materials. The determination of ignitability must be based on observations of the mold vents within 5 minutes of pouring, and the flame must be present for at least 15 seconds for the mold vent to be considered ignited. For the purpose of this determination:(i) Mold vents that ignite more than 75 percent of the time without the presence of an auxiliary ignition source are considered to ignite automatically。(a)(8) through (11). You must establish the operating according to the requirements in paragraphs (b)(2)(i) through (iii) of this section.(i) Select operating limit parameters appropriate for the capture system design that are representative and reliable indicators of the performance of the capture system. At a minimum, you must use appropriate operating limit parameters that indicate the level of the ventilation draft and damper position settings for the capture system when operating to collect emissions, including revised settings for seasonal variations. Appropriate operating limit parameters for ventilation draft include, but are not limited to: volumetric flow rate through each separately ducted hood, total volumetric flow rate at the inlet to the control device to which the capture system is vented, fan motor amperage, or static pressure.
