NR 664.1063(4)(c) (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% 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.

NR 664.1063(5) (5) If an owner or operator determines that a piece of equipment contains or contacts a hazardous waste with organic concentrations at least 10% by weight, the determination can be revised only after following the procedures in sub. (4) (a) or (b).

NR 664.1063(6) (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% by weight, the procedures in sub. (4) (a) or (b) can be used to resolve the dispute.

NR 664.1063(7) (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.

NR 664.1063(8) (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.

NR 664.1063(9) (9) Performance tests to determine if a control device achieves 95 weight percent organic emission reduction shall comply with s. NR 664.1034 (3) (a) to (d).
