Section 115.215 - Approved Test Methods

Compliance with the emission specifications, vapor control system efficiency, and certain control requirements, inspection requirements, and exemption criteria of §§ 115.211- 115.214 and 115.217 of this title (relating to Emission Specifications, Control Requirements, Alternate Control Requirements, Inspection Requirements, and Exemptions) must be determined by applying one or more of the following test methods and procedures, as appropriate.

(1) Flow rate. Test Methods 1-4 (40 Code of Federal Regulations (CFR) Part 60, Appendix A) are used for determining flow rates, as necessary.
(2) Concentration of volatile organic compounds (VOC).
(A) Test Method 18 (40 CFR Part 60, Appendix A) is used for determining gaseous organic compound emissions by gas chromatography.
(B) Test Method 25 (40 CFR Part 60, Appendix A) is used for determining total gaseous nonmethane organic emissions as carbon.
(C) Test Methods 25A or 25B (40 CFR Part 60, Appendix A) are used for determining total gaseous organic concentrations using flame ionization or nondispersive infrared analysis.
(3) Performance requirements for flares and vapor combustors.
(A) For flares, the performance test requirements of 40 CFR §60.18(b) apply.
(B) For vapor combustors, the owner or operator may consider the unit to be a flare and meet the performance test requirements of 40 CFR §60.18(b) rather than the procedures of paragraphs (1) and (2) of this section.
(C) Compliance with the requirements of 40 CFR §60.18(b) will be considered to demonstrate compliance with the emission specifications and control efficiency requirements of § 115.211 and § 115.212 of this title.
(4) Vapor pressure. Use standard reference texts or ASTM International Test Methods D323-89, D2879, D4953, D5190, D5191, or D6377 for the measurement of vapor pressure. For the purposes of temperature correction, the owner or operator shall use the actual storage temperature. Actual storage temperature of an unheated tank or vessel may be determined using either the measured temperature or the maximum local monthly average ambient temperature as reported by the National Weather Service. Actual storage temperature of a heated tank or vessel must be determined using either the measured temperature or the temperature set point of the tank or vessel.
(5) Leak determination by instrument method. Use Test Method 21 (40 CFR Part 60, Appendix A) for determining VOC leaks.
(6) Gasoline terminal test procedures. Use the additional test procedures described in 40 CFR §60.503(b) - (d) (February 14, 1989), for pre-test leak determination, emission specifications test for vapor control systems, and pressure limit in transport vessel.
(7) Vapor-tightness test procedures for marine vessels. Use 40 CFR §63.565(c) (September 19, 1995) or 40 CFR §61.304(f) (October 17, 2000) for determination of marine vessel vapor tightness.
(8) Flash point. Use ASTM Test Method D93 for the measurement of flash point.
(9) Minor modifications. Minor modifications to these test methods may be used, if approved by the executive director.
(10) Alternate test methods. Test methods other than those specified in paragraphs (1) - (8) of this section may be used if validated by 40 CFR Part 63, Appendix A, Test Method 301. For the purposes of this paragraph, substitute "executive director" each place that Test Method 301 references "administrator."
