NR 665.1033(13)(b)(b) Incinerated in a hazardous waste incinerator for which any of the following conditions has been met: NR 665.1033(13)(b)2.2. The owner or operator has designed and operates the incinerator according to the interim license requirements of subch. O. NR 665.1033(13)(c)(c) Burned in a boiler or industrial furnace for which any of the following conditions has been met: NR 665.1033(13)(c)2.2. The owner or operator has designed and operates the boiler or industrial furnace according to the interim license requirements of subch. H of ch. NR 666. NR 665.1033(14)(a)(a) Determines that the components of the closed-vent system are unsafe to monitor because monitoring personnel would be exposed to an immediate danger as a consequence of complying with sub. (11) (a) 2. b. NR 665.1033(14)(b)(b) Adheres to a written plan that requires monitoring the closed-vent system components using the procedure in sub. (11) (a) 2. b. as frequently as practicable during safe-to-monitor times. NR 665.1033 HistoryHistory: CR 05-032: cr. Register July 2006 No. 607, eff. 8-1-06; correction in (13) (a) 2. made under s. 13.92 (4) (b) 7., Stats., Register March 2013 No. 687. NR 665.1034(1)(1) Each owner or operator subject to this subchapter shall comply with the test methods and procedures requirements in this section. NR 665.1034(2)(2) When a closed-vent system is tested for compliance with no detectable emissions, as required in s. NR 665.1033 (11), the test shall comply with all of the following requirements: NR 665.1034(2)(d)2.2. A mixture of methane or n-hexane and air at a concentration of approximately, but less than, 10,000 ppm methane or n-hexane. NR 665.1034(2)(f)(f) Traverse the instrument probe around all potential leak interfaces as close to the interface as possible as described in Method 21 in appendix A of 40 CFR part 60, incorporated by reference in s. NR 660.11. NR 665.1034(2)(g)(g) Compare the arithmetic difference between the maximum concentration indicated by the instrument and the background level with 500 ppm for determining compliance. NR 665.1034(3)(a)(a) Conduct performance tests to determine total organic compound concentrations and mass flow rates entering and exiting control devices and reduce data according to all of the following methods and calculation procedures: NR 665.1034(3)(a)2.2. Method 18 or Method 25A in Appendix A of 40 CFR part 60, incorporated by reference in s. NR 660.11, for organic content. If Method 25A is used, the organic HAP used as the calibration gas shall be the single organic HAP representing the largest percent by volume of the emissions. The use of Method 25A is acceptable if the response from the high-level calibration gas is at least 20 times the standard deviation of the response from the zero calibration gas when the instrument is zeroed on the most sensitive scale. NR 665.1034(3)(a)3.3. Each performance test shall consist of 3 separate runs; conduct each run for at least one hour under the conditions that exist when the hazardous waste management unit is operating at the highest load or capacity level reasonably expected to occur. For the purpose of determining total organic compound concentrations and mass flow rates, average the results of all runs. Compute the average on a time-weighted basis.
