Steps shall be taken to repair or adjust the operation of the process to end the parameter excursion period. NR 464.09(16)(a)3.3. Steps shall be taken to minimize total HAP emissions to the atmosphere during the parameter excursion period. NR 464.09(16)(b)(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). NR 464.09(16)(b)1.1. Conduct a performance test as specified in 40 CFR 63.457 using the monitoring data specified in sub.

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. NR 464.09(16)(b)2.2. 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. NR 464.09(16)(b)3.3. 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: NR 464.09(16)(b)3.a.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.

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. NR 464.09(16)(c)(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: NR 464.09(16)(c)2.2. Repeat the procedures in subd. 1. for every day until the unsafe conditions have passed. NR 464.09(16)(c)3.3. 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. NR 464.09(16)(c)4.4. 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). NR 464.09(16)(c)5.5. 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.
