Current through Reg. 49, No. 28; July 12, 2024
For the Beaumont-Port Arthur, Dallas-Fort Worth, El Paso,
						and Houston-Galveston-Brazoria areas, as defined in §
											115.10 of
						this title (relating to Definitions) and Gregg, Nueces, and Victoria Counties,
						compliance with the requirements in this division must be determined by
						applying the following test methods, as appropriate:
(1) Methods 1 - 4 (40 Code of Federal
					 Regulations (CFR) Part 60, Appendix A) for determining flow rates, as
					 necessary;
(2) Method 18 (40 CFR
					 Part 60, Appendix A) for determining gaseous organic compound emissions by gas
					 chromatography;
(3) Method 21 (40
					 CFR Part 60, Appendix A-7) for determining volatile organic compounds
					 concentrations for the purposes of determining the presence of leaks and
					 determining breakthrough on a carbon adsorption system or carbon adsorber. If
					 the owner or operator chooses to conduct a test to verify a vapor-tight
					 requirement, Method 21 is acceptable;
(4) Method 22 (40 CFR Part 60, Appendix A)
					 for determination of visible emissions from flares;
(5) Method 25 (40 CFR Part 60, Appendix A)
					 for determining total gaseous nonmethane organic emissions as carbon;
(6) Methods 25A or 25B (40 CFR Part 60,
					 Appendix A) for determining total gaseous organic concentrations using flame
					 ionization or nondispersive infrared analysis;
(7) test method described in
					 40 CFR
					 §60.113a(a)(1)(ii)
					 (effective April 8, 1987) for measurement of storage tank seal gap;
(8) true vapor pressure must be determined
					 using standard reference texts or ASTM International Test Method D323, D2879,
					 D4953, D5190, D5191, or D6377 for the measurement of Reid vapor pressure,
					 adjusted for actual storage temperature in accordance with American Petroleum
					 Institute Publication 2517. For the purposes of temperature correction, the
					 owner or operator shall use the actual storage temperature. Actual storage
					 temperature of an unheated storage tank may be determined using the maximum
					 local monthly average ambient temperature as reported by the National Weather
					 Service. Actual storage temperature of a heated storage tank must be determined
					 using either the measured temperature or the temperature set point of the
					 storage tank;
(9) mass flow meter,
					 positive displacement meter, or similar device for measuring the volumetric
					 flow rate of flash, working, breathing, and standing emissions from crude oil
					 and condensate over a 24-hour period representative of normal operation. For
					 crude oil and natural gas production sites, volumetric flow rate measurements
					 must be made while the producing wells are operational;
(10) test methods referenced in paragraphs
					 (2), (5), and (6) of this section or Gas Processors Association Method 2286,
					 Tentative Method of Extended Analysis for Natural Gas and Similar Mixtures by
					 Temperature Programmed Gas Chromatography, to measure the concentration of
					 volatile organic compounds in flashed gases from crude oil and condensate
					 storage;
(11) test methods other
					 than those specified in this section may be used if validated by 40 CFR Part
					 63, Appendix A, Test Method 301 and approved by the executive director;
					 or
(12) minor modifications to
					 these test methods approved by the executive director.
