NR 405.025NR 405.025 Methods for calculation of increases in actual emissions. NR 405.025(1)(1) For projects that only involve existing emissions units, any increase in actual emissions from a physical change or change in the method of operation at a stationary source shall equal the sum of the difference between the projected actual emissions and the baseline actual emissions for each existing emissions unit involved in the project. NR 405.025(2)(2) For projects that only involve construction of a new emissions unit or units, any increase in actual emissions from a physical change or change in the method of operation at a stationary source shall equal the sum of the differences between the potential to emit from each new emissions unit following completion of the project and the baseline actual emissions for each unit before the project. NR 405.025(3)(3) For projects that involve existing and new emissions units, any increase in actual emissions from a physical change or change in the method of operation at a stationary source shall equal the sum of the emissions increases for each emissions unit involved in the project, using the method specified in sub. (1) for existing emissions units and the method in sub. (2) for new emissions units. NR 405.025 HistoryHistory: CR 03-118: cr. Register June 2007 No. 618, eff. 7-1-07.

NR 405.04(1)(1) All of the following concentrations shall be excluded in determining compliance with a maximum allowable increase: NR 405.04(1)(a)(a) Concentrations attributable to the increase in emissions from stationary sources which have converted from the use of petroleum products, natural gas, or both by reason of an order in effect under sections 2 (a) and (b) of the Energy Supply and Environmental Coordination Act of 1974 (15 USC 791 to 798) over the emissions from such sources before the effective date of such an order. NR 405.04(1)(b)(b) Concentrations attributable to the increase in emissions from sources which have converted from using natural gas by reason of a natural gas curtailment plan in effect pursuant to the Federal Power Act (16 USC 791a to 828c) over the emissions from such sources before the effective date of the plan. NR 405.04(1)(c)(c) Concentrations of particulate matter attributable to the increase in emissions from construction or other temporary emission-related activities of new or modified sources. NR 405.04(1)(d)(d) The increase in concentrations attributable to new sources outside the United States over the concentrations attributable to existing sources which are included in the baseline concentration. NR 405.04(1)(e)(e) Concentrations attributable to the temporary increase in emissions of sulfur dioxide, nitrogen dioxide or particulate matter from stationary sources which are affected by plan revisions approved by the administrator as meeting the criteria specified in sub. (4). NR 405.04(2)(2) No sources which have concentrations which are excluded from increment consumption under sub. (1) (a) and (b) may any longer have those concentrations excluded 5 years after the effective date of the order to which sub. (1) (a) refers or the plan to which sub. (1) (b) refers, whichever is applicable. If both such order and plan are applicable, no such exclusion may apply more than 5 years after the later of such effective dates. NR 405.04(4)(4) For purposes of excluding concentrations pursuant to sub. (1) (e), the administrator may approve a plan revision that: NR 405.04(4)(a)(a) Specifies the time over which the temporary emissions increase of sulfur dioxide, nitrogen dioxide or particulate matter would occur. Such time is not to exceed 2 years in duration unless a longer time is approved by the administrator. NR 405.04(4)(b)(b) Specifies that the time period for excluding certain contributions in accordance with par. (a) is not renewable. NR 405.04(4)(c)(c) Allows no emissions increase from a stationary source which would do either of the following: NR 405.04(4)(c)1.1. Impact a Class I area or an area where an applicable increment is known to be violated. NR 405.04(4)(c)2.2. Cause or contribute to the violation of a national ambient air quality standard. NR 405.04(4)(d)(d) Requires limitations to be in effect at the end of the time period specified in accordance with par. (a) which would insure that the emissions levels from stationary sources affected by the plan revision would not exceed those levels occurring from such sources before the plan revision was approved.

NR 405.05(2)(d)(d) Prior to the issuance of notice respecting the redesignation of an area that includes any federal lands, the department shall provide written notice to the appropriate federal land manager and the federal land manager shall be allowed 30 days to confer with the department respecting the redesignation and to submit written comments and recommendations. In redesignating any area with respect to which any federal land manager submits written comments and recommendations, the department shall publish a list of any inconsistency between such redesignation and such comments and recommendations (together with the reasons for making such redesignation against the recommendation of the federal land manager). NR 405.05(2)(e)(e) The department proposes the redesignation after consultation with the elected leadership of local and other substate general purpose governments in the area covered by the proposed redesignation.

NR 405.05(3)(b)(b) The redesignation, except any established by an Indian governing body, is specifically approved by the department.

The appropriate Indian governing body may submit to the administrator a proposal to redesignate areas Class I, Class II, or Class III provided that the following conditions are met: NR 405.05(4)(a)(a) The Indian governing body has followed procedures equivalent to those required of the department under subs. (2) and (3) (c) and (d). NR 405.05(4)(b)(b) Such redesignation is proposed after consultation with the state in which the Indian reservation is located and which border the Indian reservation. NR 405.05(5)(5) If the administrator disapproves a proposed redesignation, the classification of the area shall be that which was in effect prior to the disapproval of the redesignation. NR 405.05(6)(6) If the administrator disapproves any proposed area redesignation, the department or Indian governing body, as appropriate, may resubmit the proposal after correcting the deficiencies noted by the administrator. NR 405.05 NoteNote: The time period provided for a federal land manager’s comments in the federal regulations (not in excess of 60 days) is specified as 30 days in sub. (2) (d).
