Utah Admin. Code R315-265-1063 - Air Emission Standards for Equipment Leaks - Test Methods and Procedures

(a) Each owner or operator subject to Sections R315-265-1050 through R315-265-1064 shall comply with the test methods and procedures requirements provided in Section R315-265-1062.

(b) Leak detection monitoring, as required in Sections R315-265-1052 through R315-265-1062, shall comply with the following requirements:

(1) Monitoring shall comply with Reference Method 21 in 40 CFR part 60.

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

(3) The instrument shall be calibrated before use on each day of its use by the procedures specified in Reference Method 21.

(4) Calibration gases shall be:

(i) zero air, less than 10 ppm of hydrocarbon in air; and

(ii) a mixture of methane or n-hexane and air at a concentration of about, but less than, 10,000 ppm methane or n-hexane.

(5) The instrument probe shall be traversed around each potential leak interface as close to the interface as possible as described in Reference Method 21.

(c) When equipment is tested for compliance with no detectable emissions, as required in Subsections R315-265-1052(e), R315-265-1053(i), Section R315-265-1054, and Subsection R315-265-1057(f), the test shall comply with the following requirements:

(1) The requirements of Subsections R315-265-1062(b)(1) through R315-265-1062(b)(4) shall apply.

(2) The background level shall be determined, as set forth in Reference Method 21.

(3) The instrument probe shall be traversed around each potential leak interface as close to the interface as possible as described in Reference Method 21.

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

(d) In accordance with the waste analysis plan required by Subsection R315-265-13(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 10% by weight using the following:

(1) methods described in ASTM Methods D 2267-88, E 169-87, E 168-88, E 260-85, incorporated by reference in Section R315-260-11;

(2) method 9060A, incorporated by reference in Section R315-260-11, of "Test Methods for Evaluating Solid Waste", EPA Publication SW-846 or analyzed for its individual organic constituents; or

(3) application of the knowledge of the nature of the hazardous waste stream or the process that produced the waste. Documentation of a waste determination by knowledge is required. Examples of documentation that shall be used to support a determination under Subsection R315-265-1063(d) 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 facility or another facility that has previously been demonstrated by direct measurement to have a total organic content less than 10%, or earlier speciation analysis results on the waste stream when it can also be documented that no process changes have occurred since that analysis that could affect the waste total organic concentration.

(e) 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 Subsection R315-265-1063(d)(1) or R315-265-1063(d)(2).

(f) If an owner or operator and the director 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 Subsection R315-265-1063(d)(1) or R315-265-1063(d)(2) can 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 procured from standard reference texts or may be determined by ASTM D-2879-86, incorporated by reference in Section R315-260-11.

(i) Performance tests to determine if a control device achieves 95 weight percent organic emission reduction shall comply with the procedures of Subsections R315-265-1034(c)(1) through R315-265-1034(c)(4).
