Universal Citation: WI Admin Code § NR 665.1063

Current through August 26, 2024

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

(2) Leak detection monitoring, as required in ss. NR 665.1052 to 665.1062, shall comply with all of the following requirements:

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

(b) The detection instrument shall meet the performance criteria of Method 21.

(d) Calibration gases shall be all of the following:

1. Zero air (less than 10 ppm of hydrocarbon in air).

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.

(e) Traverse the instrument probe around all potential leak interfaces as close to the interface as possible as described in Method 21.

(3) When equipment is tested for compliance with no detectable emissions, as required in ss. NR 665.1052(5), 665.1053(9), 665.1054 and 665.1057(6), the test shall comply with all of the following requirements:

(a) Comply with sub. (2) (a) to (d).

(b) Determine the background level, as set forth in Method 21.

(c) Traverse the instrument probe around all potential leak interfaces as close to the interface as possible as described in Method 21.

(d) Compare the arithmetic difference between the maximum concentration indicated by the instrument and the background level with 500 ppm for determining compliance.

(4) According to the waste analysis plan required by s. NR 665.0013(2), an owner or operator of a facility shall determine, for each piece of equipment, whether the equipment contains or contacts a hazardous waste with an organic concentration that equals or exceeds 10 percent by weight using any of the following:

(a) Methods described in ASTM Methods D2267-88, E169-87, E168-88 or E260-85, incorporated by reference in s. NR 660.11.

(b) Analyze each sample and compute the total organic concentration of the sample using Method 9060A of EPA SW-846, incorporated by reference in s. NR 660.11, or analyze for its individual organic constituents.

(c) Application of the knowledge of the nature of the hazardous waste stream or the process by which it was produced. This method requires documentation of a waste determination. Examples of documentation that shall be used to support a determination under this paragraph include production process information documenting that no organic compounds are used, information that the waste is generated by a process that is identical to a process at the same or another facility that has previously been demonstrated by direct measurement to have a total organic content less than 10 percent or prior speciation analysis results on the same waste stream where it can also be documented that no process changes have occurred since that analysis that could affect the waste total organic concentration.

(5) If an owner or operator determines that a piece of equipment contains or contacts a hazardous waste with organic concentrations at least 10 percent by weight, the determination can be revised only after following the procedures in sub. (4) (a) or (b).

(6) When an owner or operator and the department do not agree on whether a piece of equipment contains or contacts a hazardous waste with organic concentrations at least 10 percent by weight, the procedures in sub. (4) (a) or (b) can be used to resolve the dispute.

(7) Samples used in determining the percent organic content shall be representative of the highest total organic content hazardous waste that is expected to be contained in or contact the equipment.

(8) To determine if pumps or valves are in light liquid service, the vapor pressures of constituents may be obtained from standard reference texts or may be determined by ASTM D2879-86, incorporated by reference in s. NR 660.11.

(9) Performance tests to determine if a control device achieves 95 weight percent organic emission reduction shall comply with s. NR 665.1034(3) (a) to (d).
