Current through June 24, 2024
(1) APPLICABILITY.
				  The requirements of this section apply to emissions units described in this
				  section that are located in the county of Kenosha, Manitowoc, Milwaukee,
				  Ozaukee, Racine, Sheboygan, Washington or Waukesha and that were initially
				  constructed on or before February 1, 2001.
(2) NO x emissions
				  optimization.
(a) The requirements of this
				  subsection do not apply to emissions units which are subject to the emission
				  limits of sub. (3).
(b) Except as
				  provided under par. (a), (c), or (f) the following categories of NOx emissions
				  units listed under this subsection shall complete a combustion optimization to
				  minimize NOx emissions in accordance with s.
				  NR
				  439.096 by December 31, 2002:
1. Solid fuel-fired boilers with a maximum
				  design heat input of 75 million Btu per hour or greater and operated during the
				  2000 ozone season or a later ozone season with a capacity factor of at least
				  20%.
2. Natural gas-fired boilers
				  with a maximum design heat input of 75 million Btu per hour or greater and
				  operated during the 2000 ozone season or a later ozone season with a capacity
				  factor of at least 20%.
3.
				  Distillate or residual fuel oil-fired boilers with a maximum design heat input
				  of 75 million Btu per hour or greater and operated during the 2000 ozone season
				  or a later ozone season with a capacity factor of at least 20%.
4. Cement kilns, lime kilns and calciners
				  with a maximum design heat input of 75 million Btu per hour or greater and
				  operated during the 2000 ozone season or a later ozone season with a capacity
				  factor of at least 20%.
5. Reheat
				  furnaces, annealing furnaces and galvanizing furnaces with a maximum design
				  heat input of 75 million Btu per hour or greater and operated during the 2000
				  ozone season or a later ozone season with a capacity factor of at least
				  20%.
6. Glass manufacturing
				  furnaces with a maximum design heat input of 75 million Btu per hour or greater
				  and operated during the 2000 ozone season or a later ozone season with a
				  capacity factor of at least 20%.
(c) An emissions unit described in par. (b)
				  which first operates with a capacity factor exceeding 20% in an ozone season
				  after the 2000 ozone season shall complete a combustion optimization by
				  December 31 of the calendar year following that ozone season.
(d) The owner or operator of an NO
				  x emissions unit subject to a combustion optimization
				  requirement under par. (b) shall operate the emissions unit in a manner
				  consistent with the results of the combustion optimization.
(e) The owner or operator of a source subject
				  to the NO x emissions optimization requirements of this
				  subsection shall perform monitoring sufficient to determine compliance with the
				  requirements of this subsection. The monitoring required under this paragraph
				  shall be either continuous monitoring of NO x emissions
				  or periodic monitoring of parameters adequate to ascertain the quality of the
				  combustion and shall conform to the source's approved combustion optimization
				  plan pursuant to s.
				  NR
				  439.096.
(f) An emissions unit that is capable of
				  firing secondary fuel is not subject to the requirements under this subsection
				  when utilizing only a secondary fuel if any of the following apply:
1. The emissions unit heat input capacity or
				  maximum design power output while utilizing the secondary fuel is less than the
				  applicability thresholds under this subsection.
2. The emissions unit burns the secondary
				  fuel only during any of the following periods:
a. Supply interruption or curtailment of
				  primary fuel. The secondary fuel usage under this paragraph may not exceed 500
				  hours within a 12 consecutive month time period unless the owner or operator
				  obtains a fuel variance under s.
				  NR
				  436.06.
b.
				  Periodic testing, maintenance, or operator training of the secondary fuel when
				  the periodic testing, maintenance, or operator training does not exceed a
				  combined total of 48 hours during any calendar year.
3. The secondary fuel constitutes less than 1
				  percent on an energy equivalent basis of the emissions unit's fuel consumption
				  within the most recent 12 consecutive month time period.
