Current through August 26, 2024

(1) Each remanufacturer or other person that stores or treats the hazardous secondary material subject to the provisions of this subchapter shall comply with the test methods and procedures requirements provided in this section.

(2) Leak detection monitoring, as required in ss. NR 661.1052 to 661.1062, shall comply with all of the following requirements:

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

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

(d) Calibration gases shall be all of the following:
1. Zero air of 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) The instrument probe shall be traversed around all potential leak interfaces as close to the interface as possible as described in Reference Method 21 in appendix A of 40 CFR part 60, incorporated by reference in s. NR 660.11.

(3) When equipment is tested for compliance with no detectable emissions, as required in ss. NR 661.1052(5), 661.1053(9), 661.1054, and 661.1057(6), the test shall comply with all of the following requirements:

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

(b) The background level shall be determined as set forth in Reference Method 21 in appendix A of 40 CFR part 60, incorporated by reference in s. NR 660.11.

(c) The instrument probe shall be traversed around all potential leak interfaces as close to the interface as possible as described in Reference Method 21 in appendix A of 40 CFR part 60, incorporated by reference in s. NR 660.11.

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

(4) A remanufacturer or other person that stores or treats the hazardous secondary material shall determine, for each piece of equipment, whether the equipment contains or contacts a hazardous secondary material with organic concentration that equals or exceeds 10 percent by weight using any of the following:

(a) Methods described in ASTM Methods D 2267-88, E 169-87, E 168-88, E 260-85, 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 secondary material stream or the process by which it was produced. Documentation of a material determination by knowledge is required. 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 material 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 material stream when it can also be documented that no process changes have occurred since that analysis that could affect the material total organic concentration.

(5) If a remanufacturer or other person that stores or treats the hazardous secondary material determines that a piece of equipment contains or contacts a hazardous secondary material with organic concentrations at least 10 percent by weight, the determination may be revised only after following the procedures specified in sub. (4) (a) or (b).

(6) When a remanufacturer or other person that stores or treats the hazardous secondary material and the department do not agree on whether a piece of equipment contains or contacts a hazardous secondary material with organic concentrations at least 10 percent by weight, the procedures specified in sub. (4) (a) or (b) may 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 secondary material 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 D-2879-86, 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 the procedures specified in s. NR 661.1034(3) (a) to (d).
