NR 428.06(4)(j)1.1. All emissions units participating in an ozone season NOx emissions averaging program may be considered out of compliance if either the aggregate ozone season NOx emission rate exceeds the emissions averaging plan’s emission rate limitation or the aggregate mass NOx emissions for the ozone season exceeds the plan’s aggregate mass NOx emissions limitation for the ozone season. NR 428.06(4)(j)2.2. Each emissions unit is considered in violation for each day of non-compliance until corrective action is taken to reduce emissions and achieve compliance. NR 428.06(4)(j)3.3. The department may require additional emission reductions if there are mass emissions exceeding the plan’s limit on tons of mass emissions. The department may waive the additional emission reductions if, in consultation with the public service commission, the department determines that the excess emissions were the result of an extraordinary event and that the excess emissions were an unavoidable outcome of a necessary action taken by the source to maintain electric system reliability. Additional emission reductions shall be achieved within the subsequent 3 ozone seasons’ allowable mass emission limit for all units participating in the emissions averaging plan. If there is no subsequent averaging plan for the source, the department may require a reduction in the source’s emission rate that achieves an equivalent aggregate mass emission reduction. NR 428.06(4)(j)4.4. All owners or operators of emissions units considered to be out of compliance with a plan emission rate limit or mass tons limit are liable for each violation and subject to enforcement and penalty provisions under ss. 285.83 and 285.87, Stats. NR 428.06(4)(k)(k) Monitoring requirements. The total mass emissions and heat input shall be quantified by continuous emissions monitoring equipment and procedures required by ss. NR 428.05 (4) and 428.07. NR 428.06(4)(L)(L) Recordkeeping and reporting requirements. Owners and operators shall comply with the recordkeeping and reporting requirements of s. NR 428.05 (5). NR 428.07NR 428.07 General requirements. Except as provided in s. NR 428.12, the owner or operator of an NOx emissions unit subject to the requirements of subch. I shall comply with the monitoring and reporting requirements of this subchapter. NR 428.07(1)(1) Requirements for monitoring, installation, certification and data accounting. NR 428.07(1)(a)(a) The owner or operator of an NOx emissions unit shall submit to the department a monitoring plan that describes in detail the systems to be used on the unit to satisfy the monitoring requirements of this subchapter by the following deadlines: NR 428.07(1)(a)2.2. For an emissions unit subject to emission limitations under s. NR 428.04 (2), at least 180 days prior to initial operation, or an alternative date approved by the department. NR 428.07(1)(b)(b) The owner or operator of each NOx emissions unit shall do all of the following: NR 428.07(1)(b)1.1. Install all monitoring systems required under s. NR 428.08 for monitoring NOx emissions. This includes all systems required to monitor NOx emission rate, NOx concentration, heat input and flow, in accordance with ss. NR 428.08 and 439.09. NR 428.07(1)(b)2.2. Install all monitoring systems for monitoring heat input, if required under this chapter, for developing NOx emission rate determinations expressed in pounds per million Btu. NR 428.07(1)(b)3.3. Successfully complete all certification tests and meet all operating specifications of this subchapter and 40 CFR parts 60 and 75 as applicable to the monitoring systems required for an emissions unit under subds. 1. and 2. NR 428.07(2)(2) Compliance dates. The owner or operator shall meet the requirements of sub. (1) (b) 1. to 3. on or before the following dates and shall record and report data on and after the applicable listed date as follows: NR 428.07(2)(a)(a) NOx emissions units subject to the requirements of this subchapter that commence operation before February 1, 2001 shall comply with the requirements of this subchapter by December 31, 2002. NR 428.07(2)(b)(b) NOx emissions units subject to the requirements of this subchapter that commence operation on or after February 1, 2001 shall comply with the requirements of this subchapter by the later of the following dates: NR 428.07(2)(c)(c) However, if the applicable deadline under par. (b) does not occur during an ozone season, the deadline for compliance with the requirements of this subchapter becomes the May 1 immediately following the date determined in accordance with par. (b). NR 428.07(2)(d)1.1. An NOx emissions unit with a new stack or flue for which construction is completed after the applicable deadline under par. (a), (b) or (c) shall comply with the requirements of this subchapter 90 days after the date on which emissions first exit through the new stack or flue. NR 428.07(2)(d)2.2. However, if the unit reports on an ozone season basis and the applicable deadline under subd. 1. does not occur during the ozone season, the deadline for compliance with the requirements of this subchapter becomes the May 1 immediately following the date determined in accordance with subd. 1. NR 428.07(3)(3) Reporting data prior to initial certification. The owner or operator of an NOx emissions unit under sub. (2) (b) or (c) shall determine, record and report NOx emissions, heat input, if required for purposes of compliance, and any other values required to determine NOx emissions, for example NOx emission rate and heat input or NOx concentration and stack flow, using the provisions of 40 CFR 75.70(g), from the date and hour that the unit starts operating until all required certification tests are successfully completed.
