NR 428.06(4)(4) Prospective emissions averaging plan. An owner or operator of an emissions unit who wishes to participate in an ozone season NOx emissions averaging program shall submit a prospective emissions averaging plan to notify the department of all the owner’s or operator’s emissions units participating in an ozone season NOx emissions averaging program. This plan shall establish compliance requirements for each unit and for all units in the aggregate with respect to emissions rate limitations and mass emissions limitations. The plan shall estimate each participating unit’s anticipated operation to meet these requirements. NR 428.06(4)(a)(a) Plan submission. The emissions averaging plan shall be submitted to the department no later than 90 days prior to the beginning of the ozone season covered by the plan. A revised plan may be submitted to the department no later than 30 days prior to the beginning of the ozone season covered by the plan. NR 428.06(4)(b)(b) Plan elements. The emissions averaging plan shall include the following information for each emissions unit participating in the averaging program. All information shall be provided by applicable fuel category. NR 428.06(4)(b)3.3. The projected ozone season heat input in million Btu or equivalent units. NR 428.06(4)(b)4.4. The projected average NOx emission rate, in pounds per million Btu or equivalent, and total mass emissions for the ozone season. NR 428.06(4)(b)5.5. Information sufficient to determine the emission rate and mass emission limit and the alternative compliance limit required under par. (f) for each unit. NR 428.06(4)(c)(c) Units with multiple owners. If an emissions unit has multiple owners, the unit’s mass emissions and heat input may be allocated among the owners provided all mass emissions and the entire heat input of the unit are allocated. Alternatively, the operator of a unit with multiple owners shall be allocated all mass emissions and the entire heat input. Each owner may use his or her share of mass emissions and heat input in any ozone season NOx emissions averaging plan. Each owner shall be the responsible party for compliance and liability for the owner’s share of mass emissions and heat input for the requirements of this subchapter. NR 428.06(4)(d)1.1. The emissions averaging plan shall establish an aggregate ozone season NOx emission rate limit for all of the emissions units participating in the averaging program. NR 428.06(4)(d)2.2. The aggregate ozone season NOx emission rate limit is calculated as the heat input weighted aggregate of the individual unit’s ozone season emission rate requirements less an environmental benefit factor of 0.01 pounds per million Btu or equivalent for each unit. This calculation is expressed as: Plan Emission Rate = {Sum [Projected Unit Heat Input x (Unit Emission Rate Limit – 0.01)]} / (Sum of Projected Unit Heat Inputs)
NR 428.06(4)(e)1.1. The emissions averaging plan shall establish an ozone season aggregate mass NOx emission limitation for all of the units participating in an averaging program during any ozone season after December 31, 2007. NR 428.06(4)(e)2.2. The aggregate mass emissions for all units that are eligible to participate in an emissions averaging plan may not exceed the combined allocation of all participating units’ mass emissions limitation as determined under subd. 3. NR 428.06(4)(e)3.3. Each unit participating in any ozone season NOx emissions averaging plan shall have a mass emissions limitation equal to 15,912 tons multiplied by that unit’s share of the average aggregate heat input of all eligible units of all owners determined by actual heat inputs for these units from the 1995, 1996 and 1997 ozone seasons as determined by the department. NR 428.06(4)(e)4.4. If a unit eligible to participate in an ozone season NOx emissions averaging plan is retired and replaced by another emissions unit at the same site, the mass emissions from the retired unit may still be used in a plan provided the replacement unit’s mass emissions for that ozone season are subtracted from the retired unit’s mass NOx emissions limitation determined under subd. 3. NR 428.06(4)(f)1.1. The emissions averaging plan shall establish an alternative compliance limit for each unit participating in the averaging program. NR 428.06(4)(f)2.2. The unit alternative compliance limit in mass per million Btu shall be determined by dividing the unit’s projected ozone season NOx emissions by its projected ozone season heat input. NR 428.06(4)(f)3.3. The plan shall provide calculations that demonstrate that the projected emissions units operations will not exceed the plan’s emission rate and mass limit. NR 428.06(4)(g)(g) Plan review. The emissions averaging plan shall be subject to department review and determination of completeness. The department shall make its determination of completeness and inform the owner or operator of any additional information needed in the plan within 30 days of receipt. NR 428.06(4)(h)1.1. The owner or operator of any emissions unit participating in an emissions averaging plan shall provide public notice of that plan by publication in a local newspaper at least 60 days prior to the start of the ozone season to which the plan relates and shall provide copies of the plan upon request. NR 428.06(4)(h)2.2. The notice shall indicate the purpose of the plan, the participating units and how to obtain a copy of the plan. NR 428.06(4)(i)1.1. The owners or operators of any emissions units participating in an emissions averaging plan shall submit a compliance report to the department not later than 60 days after the last day of the ozone season with information sufficient to demonstrate compliance with the plan’s emission rate and mass emissions limit. NR 428.06(4)(i)2.2. The compliance report shall provide, for each emissions unit, the heat input, NOx emission rate and total NOx mass emissions for the ozone season. The compliance report shall provide, in aggregate for all units participating in the emissions averaging plan, the ozone season NOx mass emissions, heat input in million Btu or equivalent units, and the average emission rate. The aggregate ozone season NOx emission rate shall be calculated as sum of the actual heat input of each unit times the individual unit’s actual emission rate divided by the sum of the actual heat inputs of all units. This calculation is expressed as:
