or connections to covers required by s.
NR 464.08, or if an instrument reading of 500 parts per
million by volume or greater above background is measured, or if enclosure
openings are not maintained at negative pressure, then the following corrective
actions shall be taken as soon as practicable:
1. A first effort to repair or correct the
closed-vent system shall be made as soon as practicable but no later than 5
calendar days after the problem is identified.
2. The repair or corrective action shall be
completed no later than 15 calendar days after the problem is identified. Delay
of repair or corrective action is allowed if the repair or corrective action is
technically infeasible without a process unit shutdown or if the owner or

(15) Each
owner or operator of a control device subject to the monitoring provisions of
this section shall operate the control device in a manner consistent with the
minimum or maximum, as appropriate, operating parameter value or procedure
required to be monitored under subs. (1) to (14) and established under this
chapter. Except as provided in sub. (16), s.
NR 464.03(5) or 464.06(7), operation
of the control device below minimum operating parameter values or above maximum
operating parameter values established under this chapter or failure to perform
procedures required by this chapter shall constitute a violation of the
applicable emission standard of this chapter and be reported as a period of
excess emissions.
(16) The
procedures of this paragraph apply to each owner or operator of an open
biological treatment system complying with sub. (10) whenever a monitoring
parameter excursion occurs, and the owner or operator chooses to conduct a
performance test to demonstrate compliance with the applicable emission limit.
A monitoring parameter excursion occurs whenever the monitoring parameters
specified in sub. (10) (a) 1. to 3. or any of the monitoring parameters
specified in sub. (10) (c) are below minimum operating parameter values or
above maximum operating parameter values established in sub. (14).

the parameter excursion period.
3.
Steps shall be taken to minimize total HAP emissions to the atmosphere during
the parameter excursion period.
(b) A parameter excursion is not a violation
of the applicable emission standard if the results of the performance test
conducted using the procedures in this paragraph demonstrate compliance with
the applicable emission limit in s.
NR
464.06(5) (b).
1. Conduct a performance test as specified in
40 CFR
63.457 using the monitoring data specified in
sub. (10) (a) to (c) that coincides with the time of the parameter excursion.
No maintenance or changes shall be made to the open biological treatment system
after the beginning of a parameter excursion that would influence the results
of the performance test.
2. If the
results of the performance test specified in subd. 1. demonstrate compliance
with the applicable emission limit in s.
NR
464.06(5) (b), then the parameter
excursion is not a violation of the applicable emission limit.
3. If the results of the performance test
specified in subd. 1. do not demonstrate compliance with the applicable
emission limit in s.
NR 464.06(5) (b) because the total HAP
mass entering the open biological treatment system is below the level needed to
demonstrate compliance with the applicable emission limit in s.
NR
464.06(5) (b), then the owner or
operator shall perform the following comparisons:
a. If the value of fbio (MeOH) determined
during the performance test specified in subd. 1. is within the range of values
established during the initial and subsequent performance tests approved by the
department, then the parameter excursion is not a violation of the applicable
standard.
b. If the value of fbio
(MeOH) determined during the performance test specified in subd. 1. is not
within the range of values established during the initial and subsequent
performance tests approved by the department, then the parameter excursion is a
violation of the applicable standard.
4. The results of the performance test
specified in subd. 1. shall be recorded as specified in s.
NR 464.10(6).
(c) If an owner or operator determines that
performing the required procedures under par. (b) for a nonthoroughly mixed
open biological system would expose a worker to dangerous, hazardous or
otherwise unsafe conditions, all of the following procedures shall be
performed:
1. Calculate the mass removal or
percent reduction value using the procedures specified in
40 CFR
63.457(l) except the value
for fbio (MeOH) shall be determined using the procedures in Appendix E of 40
CFR part 63, incorporated by reference in s.
NR 484.04(25r).
2. Repeat the procedures in subd. 1. for
every day until the unsafe conditions have passed.
3. A parameter excursion is a violation of
the standard if the percent reduction or mass removal determined in subd. 1. is
less than the percent reduction or mass removal standards specified in s.
NR
464.06(5) (b), as appropriate, unless
the value of fbio (MeOH) determined using the procedures in 40 CFR part 63
Appendix E, as specified in subd. 1., is within the range of fbio (MeOH) values
established during the initial and subsequent performance tests previously
approved by the department.
4. The
determination that there is a condition that exposes a worker to dangerous,
hazardous or otherwise unsafe conditions shall be documented according to
requirements in s.
NR 464.10(5) and reporting in s.
NR 464.11(6).
5. The requirements of pars. (a) and (b)
shall be performed and met as soon as practical but no later than 24 hours
after the conditions have passed that exposed a worker to dangerous, hazardous
or otherwise unsafe conditions.
