(a) An owner or operator subject to the requirements of Section 66264.1057 may elect to have all valves within a hazardous waste management unit comply with an alternative standard that allows no greater than two percent of the valves to leak.
(b) The following requirements shall be met if an owner or operator decides to comply with an alternative standard which allows two percent of the valves to leak:
(1) an owner or operator shall notify the Department that the owner or operator has elected to comply with the requirements of this section;
(2) a performance test as specified in paragraph (c) of this section shall be conducted initially upon designation, annually, and at any other time required by the Department upon a determination by the Department that a performance test is necessary to protect human health or to the environment; and
(3) if a valve leak is detected, it shall be repaired in accordance with Sections 66264.1057(d) and (e).
(c) For the purpose of determining when the alternative standard should be allowed under subsection (a), performance tests shall be conducted in the following manner:
(1) all valves subject to the requirements in Section 66264. 1057 within the hazardous waste management unit shall be monitored within one week period by the methods specified in Section 66264.1063(b);
(2) if an instrument reading of 10,000 ppm or greater is measured, a leak is detected; and
(3) the leak percentage shall be determined by dividing the number of valves subject to the requirements in Section 66264.1057 for which leaks are detected by the total number of valves subject to the requirements in Section 66264.1057 within the hazardous waste management unit.
(d) If an owner or operator decides to no longer comply with this section, the owner or operator shall notify the Department in writing that the work practice standard described in Section 66264.1057(a) through (e) will be followed.

(d) In accordance with the waste analysis plan required by Section 66264.13(b), an owner or operator of a facility shall determine, for each piece of equipment, whether the equipment contains or contacts a hazardous waste with organic concentration that equals or exceeds ten percent by weight using the following:

Examples of documentation that shall be used to support a determination under this provision 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 ten 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 total organic concentration of the waste.
(e) If an owner or operator determines that a piece of equipment contains or contacts a hazardous waste with organic concentrations at least ten percent by weight, the determination can be revised only after following the procedures in subsection (d)(1) or (d)(2) of this section.
(f) 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 ten percent by weight, the procedures in paragraph (d)(1) or (d)(2) of this section shall be used to resolve the dispute.
(g) 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.
(h) 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 under Section 66260.11).
(i) Performance tests to determine if a control device achieves 95 weight percent organic emission reduction shall comply with the procedures of Section 66264.1034(c)(1) through (c)(4).
