【正文】 ion and other scrap subject to paragraph (c) of this section at your facility provided the scrap remains segregated until charge makeup.(b) You must prepare and operate at all times according to a written certification that the foundry purchases and uses only metal ingots, pig iron, slitter, or other materials that do not include postconsumer automotive body scrap, postconsumer engine blocks, postconsumer oil filters, oily turnings, lead ponents, mercury switches, plastics, or free organic liquids. For the purpose of this paragraph (b), “free organic liquids” is defined as material that fails the paint filter test by EPA Method 9095A, “Paint Filter Liquids Test” (Revision 1, December 1996), as published in EPA Publication SW–846 “Test Methods for Evaluating Solid Waste, Physical/Chemical Methods” (incorporated by reference—see 167。 73 FR 7218, Feb. 7, 2008]Operation and Maintenance Requirements167。(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. Any parameter for damper position setting may be used that indicates the duct damper position related to the fully open setting.(ii) For each operating limit parameter selected in paragraph (b)(2)(i) of this section, designate the value or setting for the parameter at which the capture system operates during the process operation. If your operation allows for more than one process to be operating simultaneously, designate the value or setting for the parameter at which the capture system operates during each possible configuration that you may operate ( ., the operating limits with one furnace melting, two melting, as applicable to your plant).(iii) Include documentation in your plan to support your selection of the operating limits established for your capture system. This documentation must include a description of the capture system design, a description of the capture system operating during production, a description of each selected operating limit parameter, a rationale for why you chose the parameter, a description of the method used to monitor the parameter according to the requirements of 167。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。(a)(2), you must conduct a performance test no later than 180 calendar days after the pliance date that is specified in 167。 that applies to you.(b) For each work practice standard 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。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 m
