【正文】 ssions from metal melting furnaces, scrap preheaters, pouring areas, pouring stations, automated conveyor and pallet cooling lines, automated shakeout lines, and mold and core making lines. This subpart also covers fugitive emissions from foundry operations.(c) An affected source is existing if you menced construction or reconstruction of the affected source before December 23, 2002.(d) An affected source is new if you menced construction or reconstruction of the affected source on or after December 23, 2002. An affected source is reconstructed if it meets the definition of “reconstruction” in 167。Am I subject to this subpart?You are subject to this subpart if you own or operate an iron and steel foundry that is (or is part of) a major source of hazardous air pollutant (HAP) emissions. Your iron and steel foundry is a major source of HAP for purposes of this subpart if it emits or has the potential to emit any single HAP at a rate of 10 tons or more per year or any bination of HAP at a rate of 25 tons or more per year or if it is located at a facility that emits or has the potential to emit any single HAP at a rate of 10 tons or more per year or any bination of HAP at a rate of 25 tons or more per year as defined in 167。69 FR 21923, Apr. 22, 2004, unless otherwise noted. What this Subpart Covers167。Subpart EEEEE—National Emission Standards for Hazardous Air Pollutants for Iron and Steel FoundriesSource: What is the purpose of this subpart?This subpart establishes national emission standards for hazardous air pollutants (NESHAP) for iron and steel foundries. This subpart also establishes requirements to demonstrate initial and continuous pliance with the emissions limitations, work practice standards, and operation and maintenance requirements in this subpart.167。.[69 FR 21923, Apr. 22, 2004, as amended at 73 FR 7218, Feb. 7, 2008]167。.167。(b) or (c), as applicable, no later than April 22, 2005.(c) If you have a new affected source for which the initial startup date is on or before April 22, 2004, you must ply with each emissions limitation, work practice standard, and operation and maintenance requirement in this subpart that applies to you by April 22, 2004.(d) If you have a new affected source for which the initial startup date is after April 22, 2004, you must ply with each emissions limitation, work practice standard, and operation and maintenance requirement in this subpart that applies to you upon initial startup.(e) If your iron and steel foundry is an area source that bees a major source of HAP, you must meet the requirements of 167。. Note that several of these notifications must be submitted before the pliance date for your affected source.Emissions Limitations167。 or(ii) pound of PM per ton (lb/ton) of metal charged, or(iii) gr/dscf of total metal HAP。(e) for a scrap preheater at an existing iron and steel foundry or in 167。(g)。(g).(b) You must meet each operating limit in paragraphs (b)(1) through (5) of this section that applies to you.(1) You must install, operate, and maintain a capture and collection system for all emissions sources subject to an emissions limit for VOHAP or TEA in paragraphs (a)(8) through (11) of this section.(i) Each capture and collection system must meet accepted engineering standards, such as those published by the American Conference of Governmental Industrial Hygienists.(ii) You must operate each capture system at or above the lowest value or settings established as operating limits in your operation and maintenance plan.(2) You must operate each wet scrubber applied to emissions from a metal melting furnace, scrap preheater, pouring area, or pouring station subject to an emissions limit for PM or total metal HAP in paragraphs (a)(1) through (6) of this section such that the 3hour average pressure drop and scrubber water flow rate does not fall below the minimum levels established during the initial or subsequent performance test.(3) You must operate each bustion device applied to emissions from a cupola metal melting furnace subject to the emissions limit for VOHAP in paragraph (a)(8) of this section, such that the 15minute average bustion zone temperature does not fall below 1,300 degrees Fahrenheit ( 176。 and(ii) The 3hour average pH of the scrubber blowdown, as measured by a continuous parameter monitoring system (CPMS), does not exceed or the pH of the scrubber blowdown, as measured once every 8 hours during process operations, does not exceed .(c) If you use a control device other than a baghouse, wet scrubber, wet acid scrubber, or bustion device, you must prepare and submit a monitoring plan containing the information listed in paragraphs (c)(1) through (5) of this section. The monitoring plan is subject to approval by the Administrator.(1) A description of the device。 verifying the performance of the device for reducing emissions of PM, total metal HAP, VOHAP, or TEA to the levels required by this subpart。(b)。 and(5) Operating parameter limits based on monitoring data collected during the performance test.[69 FR 21923, Apr. 22, 2004, as amended at 73 FR 7218, Feb. 7, 2008]Work Practice Standards167。). Any postconsumer engine blocks, postconsumer oil filters, or oily turnings that are processed and/or cleaned to the extent practicable such that the materials do not include lead ponents, mercury switches, chlorinated plastics, or free organic liquids can be included in this certification.(c) You must prepare and operate at all times according to a written plan for the selection and inspection of iron and steel scrap to minimize, to the extent practicable, the amount of organics and HAP metals in the charge materials used by the iron and steel foundry. This scrap selection and inspection plan is subject to approval by the Administrator. You must keep a copy of the plan onsite and readily available to all plant personnel with materials acquisition or inspection duties. You must provide a co
