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。(c)(5).(f) You must meet the notification and schedule requirements in 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。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 emi
