monitoring equipment shall complete the installation and performance tests of
the equipment and begin monitoring and recording not later than April 1, 1989,
except as provided in pars. (a) and (b). The department may grant requests for
extensions of the time provided for installation of monitors for facilities
unable to meet the prescribed time frame if the owner or operator of the
facility demonstrates that good faith efforts have been made to obtain and
install the devices within the prescribed time frame.
(a) For new sources, monitoring and recording
shall begin upon startup.
(b) For
boilers connected to a single stack which have individual coal burning rates of
less than 25,000 tons per year but which have a combined coal burning rate of
25,000 tons or more per year, monitoring and recording shall begin not later
than January 1, 1993.
(4) MONITORING SYSTEM MALFUNCTION. The
department may grant a temporary exemption from the monitoring and reporting
requirements of this section during any period of monitoring system malfunction
if the source owner or operator shows, to the satisfaction of the department,
that the malfunction was unavoidable and is being repaired as expeditiously as
practicable.
(5) MINIMUM MONITORING

equal to or greater than 250 million Btu per hour shall install, calibrate,
maintain and operate a continuous monitoring system which meets the performance
specifications of sub. (6) for the measurement of opacity from each stack
serving a coal fired boiler or boilers with a maximum combined coal burning
rate equal to or greater than 25,000 tons per year, unless the source utilizes
an alternative method of compliance determination approved, in writing, by the
department.
2.
Sulfur
dioxide. The owner or operator of any steam generating unit shall
install, calibrate, maintain and operate a continuous monitoring system which
meets the performance specifications of sub. (6) for the measurement of sulfur
dioxide if one of the following applies:
a.
The facility total heat input capacity is equal to or greater than 250 million
Btu per hour and the facility has a control system which reduces sulfur dioxide
emissions by more than 5% of the uncontrolled sulfur dioxide emission
rate.
b. The maximum coal burning
rate of all boilers at the facility which emit to a stack without a sulfur
dioxide control system is equal to or greater than 100,000 tons of coal per
year, unless the source utilizes an alternative method of compliance
determination approved, in writing, by the department which meets the
requirements of s.
NR 439.085.
3. Nitrogen oxides. The owner or operator of
a fossil fuel fired steam generating unit with a capacity greater than 1000
million Btu per hour heat input which is located in a nonattainment area for
nitrogen oxides shall install, calibrate, maintain and operate a continuous

emits nitrogen oxides at levels 30% or more below the applicable emission
limit.
4. Oxygen or carbon dioxide.
The owner or operator of a fossil fuel fired steam generating unit where
measurement of oxygen or carbon dioxide in the flue gas is required to convert
either sulfur dioxide or nitrogen oxides continuous emission monitoring data,
or both, to units of the applicable emission limitation shall install,
calibrate, operate and maintain a continuous monitoring system for the
measurement of percent oxygen or carbon dioxide which meets the performance
specifications of sub. (6).
