Section 285.48 - Nitrogen oxide emissions reductions(1) DEFINITIONS. In this section:(a) "Call" means a call to implement a state implementation plan that is issued by the federal environmental protection agency before October 29, 1999, or after that date arising out of a call issued before that date, including a call issued after that date pursuant to a federal court order or otherwise.(b) "Electric cooperative" has the meaning given in s. 76.48(1g) (c) .(c) "Midcontinent area" has the meaning given in s. 16.958(1) (e) .(cm) "Nonutility stationary or mobile source" means a stationary or mobile source that is not an electric generating facility owned by a public utility or electric cooperative.(d) "Northwestern county" means Ashland, Barron, Bayfield, Buffalo, Burnett, Chippewa, Clark, Douglas, Dunn, Eau Claire, Iron, Jackson, La Crosse, Monroe, Pepin, Pierce, Polk, Price, Rusk, Sawyer, St. Croix, Taylor, Trempealeau, Vernon or Washburn county.(e) "Other county" means a county that is not a northwestern county.(f) "Public utility" has the meaning given in s. 196.01(5) .(g) "State implementation plan" means a state implementation plan for control of atmospheric ozone in another state.(h) "Summer" means the period beginning on May 1 and ending on September 30 of each year.(2) APPLICABILITY. This section applies if the department of natural resources, pursuant to a call, issues a state implementation plan that requires electric generating facilities in the midcontinent area of this state to comply with nitrogen oxide emission reduction requirements. If the department of natural resources issues such a plan, the department of natural resources shall notify the department of administration and the public service commission. The notice shall specify the date on which electric generating facilities in the midcontinent area of this state are required to comply with the initial nitrogen oxide emission reduction requirements.(3) NITROGEN OXIDE EMISSIONS STANDARDS AND LIMITATIONS.(a) In establishing nitrogen oxide emission reduction requirements for the control of atmospheric ozone in another state pursuant to a call, the department may not, in a state implementation plan, by rule or through the adoption of control strategies, establish nitrogen oxide emissions standards or limitations that do any of the following:1. Require less than 2,234 tons, or the greater number of tons determined under par. (d) 1., in total nitrogen oxide emissions each summer from all electric generating facilities located in northwestern counties that are owned by electric cooperatives.2. Require less than 315 tons, or the greater number of tons determined under par. (d) 1., in total nitrogen oxide emissions each summer from all electric generating facilities located in northwestern counties that are owned by public utilities.3. Require less than 15,157 tons, or the greater number of tons determined under par. (d) 1., in total nitrogen oxide emissions each summer from all electric generating facilities located in other counties owned by public utilities or electric cooperatives.(b) The department shall issue emissions allowances in a number that is sufficient to allow the emissions specified in par. (a).(c) In establishing nitrogen oxide emission reduction requirements for the control of atmospheric ozone in another state pursuant to a call, the department may not, with respect to any nonutility stationary or mobile source in this state, in a state implementation plan, by rule or through the adoption of control strategies, establish nitrogen oxide emissions standards or limitations that do any of the following:1. Require any reductions in nitrogen oxide emissions for any boiler, turbine or internal combustion engine the designed heat input of which is 250 million British thermal units per hour or less.2. Require reductions of nitrogen oxide emissions that are in addition to those reductions required by or projected for nonutility stationary or mobile sources based on source-specific nitrogen oxide inventory data or other subinventory information used by the federal environmental protection agency to establish state nitrogen oxide emission budgets concerning interstate pollution transport.3. Require any additional reductions of nitrogen oxide emissions from nonutility stationary or mobile sources in this state due to this section, including the reduction requirements under par. (a).(d) If the department of natural resources implements a state implementation plan specified in sub. (2) in a manner that requires reductions in nitrogen oxide emissions that are lower than the reductions set forth in the call published on October 27, 1998, the department of natural resources shall do each of the following: 1. Determine the amounts by which the number of tons specified in par. (a) 1., 2. and 3. shall be increased to reflect the lower reductions.2. Take action that is necessary to relax any related emissions control requirements in a manner that reflects the lower reductions.2m. Determine the amounts by which reduction requirements for any nonutility stationary or mobile source in this state shall be relaxed to reflect the lower reductions.3. Determine the amount by which the $2,400,000 in assessments under s. 196.86(2) shall be decreased to reflect the lower reductions and provide notice of the decreased amount to the public service commission.4. Determine the amount by which the $2,500,000 that is transferred to the air quality improvement fund under s. 16.958(2) (a) shall be decreased to reflect the lower reductions and provide notice of the decreased amount to the department of administration.(4) LOW-INCOME WEATHERIZATION AND ENERGY CONSERVATION MEASURES; RENEWABLE ENERGY USES. The department shall ensure that at least 866 tons of total annual reductions in nitrogen oxide emissions required under the state implementation plan are achieved through any of the following: (a) The use of renewable energy, including renewable energy that is provided by electric providers for the purpose of complying with the requirements of s. 196.378(2) (a) 2 , or renewable energy that is used under programs under s. 196.374 .(b) The implementation of low-income weatherization and energy conservation measures, including programs established under s. 16.957(2) (a) or programs under s. 196.374 .1999 a. 9, 75; 2005 a. 141; 2009 a. 180.
