NR 463.166(5)(b)(b) Use Equation 10 to compute the aluminum mass-weighted HCl emissions for the secondary aluminum processing unit. Compliance is achieved if the mass-weighted emissions for the secondary aluminum processing unit (EcHCl) is less than or equal to the emission limit for the secondary aluminum processing unit (LcHCl) calculated using Equation 2 in s. NR 463.13 (11).

NR 463.166(5)(c)(c) Use Equation 11 to compute the aluminum mass-weighted D&F emissions for the secondary aluminum processing unit. Compliance is achieved if the mass-weighted emissions for the secondary aluminum processing unit is less than or equal to the emission limit for the secondary aluminum processing unit. The emission limit for the secondary aluminum processing unit (LcD&F) is calculated using Equation 3 in s. NR 463.13 (11).

NR 463.166(5)(d)(d) As an alternative to using the equations in pars. (a) to (c), the owner or operator may demonstrate compliance for a secondary aluminum processing unit by demonstrating that each existing group 1 furnace is in compliance with the emission limits for a new group 1 furnace in s. NR 463.13 (9) and that each existing in-line fluxer is in compliance with the emission limits for a new in-line fluxer in s. NR 463.13 (10).

NR 463.17(1)(a)(a) As required by s. NR 460.08 (2) (a), the owner or operator shall provide notification for an area source that subsequently increases its emissions such that the source is a major source subject to the standard.

NR 463.17(1)(b)(b) The owner or operator of a new or reconstructed affected source, or a source that has been reconstructed such that it is an affected source, that has an initial startup after September 24, 2002 and for which an application for approval of construction or reconstruction is not required under ch. NR 406, shall provide notification that the source is subject to the standard.

NR 463.17(1)(c)(c) As required by s. NR 460.08 (2) (d), the owner or operator of a new or reconstructed major affected source that has an initial startup after September 24, 2002 and for which an application for approval of construction or reconstruction is required by ch. NR 406 shall provide all the following notifications:

NR 463.17(1)(c)1.1. Intention to construct a new major affected source, reconstruct a major source or reconstruct a major source such that the source becomes a major affected source.

NR 463.17(1)(c)2.2. Date when construction or reconstruction was commenced, submitted simultaneously with the application for approval of construction or reconstruction if construction or reconstruction was commenced before September 24, 2002, or no later than 30 days after the date construction or reconstruction commenced if construction or reconstruction commenced after September 24, 2002.

NR 463.17(1)(d)(d) As required by s. NR 460.08 (2) (d), after September 24, 2002, an owner or operator who intends to construct a new affected source or reconstruct an affected source subject to this subchapter, or reconstruct a source such that it becomes an affected source subject to this subchapter, shall provide notification of the intended construction or reconstruction. The notification shall include all the information required for an application for approval of construction or reconstruction as required by ch. NR 406. For major sources, the application for approval of construction or reconstruction may be used to fulfill these requirements. The application shall be submitted according to one of the following, as applicable:

NR 463.17(1)(d)1.1. The application shall be submitted as soon as practicable before the construction or reconstruction is planned to commence, but no sooner than September 24, 2002, if the construction or reconstruction commences after September 24, 2002.

NR 463.17(1)(d)2.2. The application shall be submitted as soon as practicable before startup but no later than 90 days after September 24, 2002 if the construction or reconstruction had commenced and initial startup had not occurred before September 24, 2002.
