NR 409.04(1)(b)(b) Burns fuel that does not include any coal or coal-derived fuel, except coal-derived gaseous fuel with a total sulfur content no greater than natural gas. NR 409.04(1)(c)(c) Burns gaseous fuel with an annual average sulfur content of 0.05% or less by weight, as determined under sub. (4) and nongaseous fuel with an annual average sulfur content of 0.05% or less by weight, as determined under sub. (4). NR 409.04(2)(b)(b) The exemption under par. (a) shall be effective on January 1 of the first full calendar year for which the unit meets the requirements of sub. (1). By December 31 of the first year for which the unit is to be exempt under this section, a statement signed by the designated representative, or, if no designated representative has been authorized, a certifying official of each owner of the unit shall be submitted to the department, and a copy of the statement shall be submitted to the administrator. The statement shall be submitted in a format prescribed by the administrator, shall identify the unit, state the nameplate capacity of each generator served by the unit and the fuels currently burned or expected to be burned by the unit and their sulfur content by weight, and state that the owners and operators of the unit will comply with sub. (6). NR 409.04(2)(c)(c) After receipt of the statement under par. (b), the department shall revise under s. NR 409.12 (4) the operation permit covering the source at which the unit is located, if the source has an operation permit, to add the provisions and requirements of the exemption under sub. (1), par. (a), and subs. (4) and (6). NR 409.04(3)(a)(a) Any new utility unit that meets the requirements of sub. (1) and that is allocated one or more allowances under 40 CFR part 73 shall be exempt from this chapter, except for the provisions of this section, 40 CFR 72.2 to 72.6, and 40 CFR 72.10 to 72.13, if the designated representative, or, if no designated representative has been authorized, a certifying official of each owner of the unit submits to the department and the administrator a statement, in a format prescribed by the administrator, that does all of the following: NR 409.04(3)(a)1.1. Identifies the unit and states the nameplate capacity of each generator served by the unit and the fuels currently burned or expected to be burned by the unit and their sulfur content by weight. NR 409.04(3)(a)3.3. Surrenders allowances equal in number to, and with the same or earlier compliance use date as, all of those allocated to the unit under 40 CFR part 73 for the first year that the unit is to be exempt under this section and for each subsequent year.

NR 409.12 (4) the operation permit covering the source at which the unit is located, if the source has such a permit, to add the provisions and requirements of the exemption under sub. (1), par. (a), and subs. (4) and (6). NR 409.04(4)(4) Compliance demonstration. Compliance with the requirement that fuel burned during the year have an annual average sulfur content of 0.05% by weight or less shall be determined using a method of determining sulfur content that provides information with reasonable precision, reliability, accessibility and timeliness, in accordance with one of the following: NR 409.04(4)(a)(a) For gaseous fuel burned during the year, if natural gas is the only gaseous fuel burned, the requirement is assumed to be met. NR 409.04(4)(b)(b) For gaseous fuel burned during the year where other gas in addition to or besides natural gas is burned, the requirement is met if the annual average sulfur content is equal to or less than 0.05% by weight. The annual average sulfur content, as a percentage by weight, for the gaseous fuel burned shall be calculated as follows: where:
%Sannual is the annual average sulfur content of the fuel burned during the year by the unit, as a percentage by weight
%Sn is the sulfur content of the nth sample of the fuel delivered during the year to the unit, as a percentage by weight
Vn is the volume of the fuel in a delivery during the year to the unit of which the nth sample is taken, in standard cubic feet; or, for fuel delivered during the year to the unit continuously by pipeline, volume of the fuel delivered starting from when the nth sample of the fuel is taken until the next sample of the fuel is taken, in standard cubic feet
dn is the density of the nth sample of the fuel delivered during the year to the unit, in lb per standard cubic foot
n is each sample taken of the fuel delivered during the year to the unit, taken at least once for each delivery; or, for fuel that is delivered during the year to the unit continuously by pipeline, at least once each quarter during which the fuel is delivered
NR 409.04(4)(c)(c) For nongaseous fuel burned during the year, the requirement is met if the annual average sulfur content is equal to or less than 0.05% by weight. The annual average sulfur content, as a percentage by weight, shall be calculated using the equation in par. (b). In lieu of the factor, volume times density, Vndn, in the equation, the factor, mass Mn, may be used, where Mn is: mass of the nongaseous fuel in a delivery during the year to the unit of which the nth sample is taken, in pounds; or, for fuel delivered during the year to the unit continuously by pipeline, mass of the nongaseous fuel delivered starting from when the nth sample of the fuel is taken until the next sample of the fuel is taken, in pounds.
