NR 664.1033(15)(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. (12) (a) 2. b.

NR 664.1033(15)(b)(b) Adheres to a written plan that requires monitoring the closed-vent system components using the procedure in sub. (12) (a) 2. b. as frequently as practicable during safe-to-monitor times.

NR 664.1033 HistoryHistory: CR 05-032: cr. Register July 2006 No. 607, eff. 8-1-06; correction in (14) (a) 2. made under s. 13.92 (4) (b) 7., Stats., Register March 2013 No. 687.

NR 664.1034(1)(1) Each owner or operator subject to this subchapter shall comply with the test methods and procedures requirements in this section.

NR 664.1034(2)(2) When a closed-vent system is tested for compliance with no detectable emissions, as required in s. NR 664.1033 (12), the test shall comply with all of the following requirements:

NR 664.1034(2)(a)(a) Monitoring shall comply with Method 21 in appendix A of 40 CFR part 60, incorporated by reference in s. NR 660.11.

NR 664.1034(2)(b)(b) The detection instrument shall meet the performance criteria of Method 21 in appendix A of 40 CFR part 60, incorporated by reference in s. NR 660.11.

NR 664.1034(2)(c)(c) The instrument shall be calibrated before use on each day of its use by the procedures in Method 21 in appendix A of 40 CFR part 60, incorporated by reference in s. NR 660.11.

NR 664.1034(2)(d)1.1. Zero air (less than 10 ppm of hydrocarbon in air).

NR 664.1034(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 664.1034(2)(e)(e) Determine the background level according to Method 21 in appendix A of 40 CFR part 60, incorporated by reference in s. NR 660.11.

NR 664.1034(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 664.1034(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 664.1034(3)(3) Performance tests to determine compliance with s. NR 664.1032 (1) and with the total organic compound concentration limit of s. NR 664.1033 (3) shall comply with all of the following:

NR 664.1034(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 664.1034(3)(a)1.1. Method 2 in appendix A of 40 CFR part 60, incorporated by reference in s. NR 660.11, for velocity and volumetric flow rate.

NR 664.1034(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 664.1034(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.
