is the HCl emission limit for individual emission unit i in sub. (9) (d) for a group 1 furnace or in sub. (10) (a) for an in-line fluxer

is the HCl emission limit for the secondary aluminum processing unit

NR 463.13 NoteNote: In-line fluxers using no reactive flux materials cannot be included in this calculation since they are not subject to the HCl limit.

NR 463.13(11)(c)(c) The owner or operator may not discharge or allow to be discharged to the atmosphere any 3-day, 24-hour rolling average emissions of D&F in excess of:

(Equation 3)

is the D&F emission limit for individual emission unit i in sub. (9) (c) for a group 1 furnace

is the D&F emission limit for the secondary aluminum processing unit

NR 463.13 NoteNote: Clean charge furnaces cannot be included in this calculation since they are not subject to the D&F limit.

NR 463.13(11)(d)(d) The owner or operator of a SAPU at a secondary aluminum production facility that is a major source may demonstrate compliance with the emission limits of pars. (a) to (c) by demonstrating that each emission unit within the SAPU is in compliance with the applicable emission limits of subs. (9) and (10).

NR 463.13(11)(e)(e) The owner or operator of a SAPU at a secondary aluminum production facility that is an area source may demonstrate compliance with the emission limits of par. (c) by demonstrating that each emission unit within the SAPU is in compliance with the emission limit of sub. (9) (c).

NR 463.13(11)(f)(f) With the prior approval of the department, an owner or operator may redesignate any existing group 1 furnace or in-line fluxer at a secondary aluminum production facility as a new emission unit. Any emission unit so redesignated may thereafter be included in a new SAPU at that facility. Any redesignation shall be solely for the purpose of this MACT standard and shall be irreversible.

NR 463.14(1)(a)(a) On and after the compliance date established by s. NR 463.115, the owner or operator shall operate all new and existing affected sources and control equipment according to the requirements in this section.

NR 463.14(1)(b)(b) The owner or operator of an existing sweat furnace that meets the specifications of s. NR 463.13 (6) shall operate the sweat furnace and control equipment according to the requirements of this section on and after the compliance date established by s. NR 463.115.

NR 463.14(1)(c)(c) The owner or operator of a new sweat furnace that meets the specifications of s. NR 463.13 (6) shall operate the sweat furnace and control equipment according to the requirements of this section by March 23, 2000 or upon startup, whichever is later.

Summary of Operating Requirements for New and Existing Affected Sources and Emission Units

a Thermal chip dryers, scrap dryers, delacquering kilns, dross-only furnaces, in-line fluxers and group 1 furnaces including melting and holding furnaces.

b OM&M plan- Operation, maintenance, and monitoring plan.

c Site-specific monitoring plan. Owners and operators of group 1 furnaces without control devices shall include a section in their OM&M plan that documents work practices and pollution prevention measures, including procedures for scrap inspection, by which compliance is achieved with emission limits and process or feed parameter-based operating requirements. This plan and the testing to demonstrate adequacy of the monitoring plan shall be developed in coordination with and approved by the department.

NR 463.14(2)(2) Labeling. The owner or operator shall provide and maintain easily visible labels posted at each group 1 furnace, group 2 furnace, in-line fluxer, scrap dryer, delacquering kiln and decoating kiln that identify the applicable emission limits and means of compliance, including all of the following:
