NR 462.06(2)(a)7. 7. If you demonstrate compliance with an applicable mercury emission limit through fuel analysis, and you plan to burn a new type of fuel, you shall recalculate the mercury emission rate using Equation 11 of s.

NR 462.06(2)(a)7.c. c. Recalculate the mercury emission rate from your boiler or process heater under these new conditions using Equation 11 of s. NR 462.05 (7). The recalculated mercury emission rate shall be less than the applicable emission limit.

NR 462.06(2)(a)8. 8. If you demonstrate compliance with an applicable mercury emission limit through performance testing, and you plan to burn a new type of fuel or a new mixture of fuels, you shall recalculate the maximum mercury input using Equation 7 of s. NR 462.05 (7). If the results of recalculating the maximum mercury input are higher than the maximum mercury input level established during the previous performance test, then you shall conduct a new performance test within 60 days of burning the new fuel type or fuel mixture according to the procedures in s. NR 462.05 (3) to demonstrate that the mercury emissions do not exceed the emission limit. You shall also establish new operating limits based on this performance test according to the procedures in s. NR 462.05 (7) (c).

NR 462.06(2)(a)9. 9. If your unit is controlled with a fabric filter, and you demonstrate continuous compliance using a bag leak detection system, you shall initiate corrective action within one hour of a bag leak detection system alarm and complete corrective actions according to your SSMP and operate and maintain the fabric filter system such that the alarm does not sound more than 5% of the operating time during a 6-month period. You shall also keep records of the date, time and duration of each alarm, the time corrective action was initiated and completed and a brief description of the cause of the alarm and the corrective action taken. You shall also record the percent of the operating time during each 6-month period that the alarm sounds. In calculating this operating time percentage, if inspection of the fabric filter demonstrates that no corrective action is required, no alarm time is counted. If corrective action is required, each alarm shall be counted as a minimum of one hour. If you take longer than one hour to initiate corrective action, the alarm time shall be counted as the actual amount of time taken to initiate corrective action.

NR 462.06(2)(d) (d) Consistent with ss. NR 460.05 (4) and 460.06 (4) (a), deviations that occur during a period of startup, shutdown or malfunction are not violations if you demonstrate to the department’s satisfaction that you were operating in accordance with your SSMP. The department will determine whether deviations that occur during a period of startup, shutdown or malfunction are violations, according to the provisions in s. NR 460.05 (4).

NR 462.06(3) (3) How do I demonstrate continuous compliance under the emission averaging provisions?
