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:

NR 464.09(11)(f)1. 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.

NR 464.09(11)(f)2. 2. The repair or corrective action shall be completed no later than 15 calendar days after the problem is identified.

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.

NR 464.09(16)(b)3.b. 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.

NR 464.09(16)(b)4. 4. The results of the performance test specified in subd. 1. shall be recorded as specified in s. NR 464.10 (6).

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)1. 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).

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.
