【正文】 Subpart EEEEE—National Emission Standards for Hazardous Air Pollutants for Iron and Steel FoundriesSource: 69 FR 21923, Apr. 22, 2004, unless otherwise noted. What this Subpart Covers167。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。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, as amended at 73 FR 7218, Feb. 7, 2008]167。What parts of my foundry does this subpart cover?(a) The affected source is each new or existing iron and steel foundry.(b) This subpart covers emissions 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。.167。When do I have to ply with this subpart?(a) Except as specified in paragraph (b) of this section, if you have an existing affected source, you must ply with each emissions limitation, work practice standard, and operation and maintenance requirement in this subpart that applies to you no later than April 23, 2007. Major source status for existing affected sources must be determined no later than April 23, 2007.(b) If you have an existing affected source, you must ply with the work practice standards in 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。(c)(5).(f) You must meet the notification and schedule requirements in 167。. Note that several of these notifications must be submitted before the pliance date for your affected source.Emissions Limitations167。What emissions limitations must I meet?(a) You must meet the emissions limits or standards in paragraphs (a)(1) through (11) of this section that apply to you. When alternative emissions limitations are provided for a given emissions source, you are not restricted in the selection of which applicable alternative emissions limitation is used to demonstrate pliance.(1) For each electric arc metal melting furnace, electric induction metal melting furnace, or scrap preheater at an existing iron and steel foundry, you must not discharge emissions through a conveyance to the atmosphere that exceed either the limit for particulate matter (PM) in paragraph (a)(1)(i) of this section or, alternatively the limit for total metal HAP in paragraph (a)(1)(ii) of this section:(i) grains of PM per dry standard cubic foot (gr/dscf), or(ii) gr/dscf of total metal HAP.(2) For each cupola metal melting furnace at an existing iron and steel foundry, you must not discharge emissions through a conveyance to the atmosphere that exceed either the limit for PM in paragraph (a)(2)(i) or (ii) of this section or, alternatively the limit for total metal HAP in paragraph (a)(2)(iii) or (iv) of this section:(i) gr/dscf of PM。 or(ii) pound of PM per ton (lb/ton) of metal charged, or(iii) gr/dscf of total metal HAP。 or(iv) pound of total metal HAP per ton (lb/ton) of metal charged.(3) For each cupola metal melting furnace or electric arc metal melting furnace at a new iron and steel foundry, you must not discharge emissions through a conveyance to the atmosphere that exceed either the limit for PM in paragraph (a)(3)(i) of this section or, alternatively the limit for total metal HAP in paragraph (a)(3)(ii) of this section:(i) gr/dscf of PM, or(ii) gr/dscf of total metal HAP.(4) For each electric induction metal melting furnace or scrap preheater at a new iron and steel foundry, you must not discharge emissions through a conveyance to the atmosphere that exceed either the limit for PM in paragraph (a)(4)(i) of this section or, alternatively the limit for total metal HAP in paragraph (a)(4)(ii) of this section:(i) gr/dscf of PM, or(ii) gr/dscf of total metal HAP.(5) For each pouring station at an existing iron and steel foundry, you must not discharge emissions through a conveyance to the atmosphere that exceed either the limit for PM in paragraph (a)(5)(i) of this section or, alternatively the limit for total metal HAP
