Section 139.14 - Emissions of VOCs(a) The following are applicable to tests for determining volatile organic content: (1) Test methods and procedures for the total volatiles content, solids content, exempt solvent content, water content and density of surface coatings shall be equivalent to those specified in § 139.4(1) and (5) (relating to references).(2) Test methods and procedures for VOCs in effluent water shall be equivalent to those specified in § 139.4(16), expressed as pentane.(3) For determining the solvent content of wastes in dry cleaning facilities, test methods and procedures shall be equivalent to those specified in § 139.4(17).(4) Results shall be reported in accordance with the units specified in the appropriate section of Chapter 129 (relating to standards for sources).(b) The following are applicable to tests for determining the emissions of VOCs:(1) Test methods for VOC emissions shall use a technique having at least a 95% collection efficiency for VOCs.(2) Except for those sources or systems specified in this subsection, the test methods and procedures and equipment for VOCs, excluding carbon dioxide, carbon monoxide and methane shall be equivalent to those specified in EPA Method 25 or as specified in § 139.4(5). The owner or operator of a source may exclude ethane from the VOC measurement. If ethane is excluded, the measurement of ethane shall be reported separately.(3) For gasoline vapor recovery systems, test methods and procedures and equipment for VOCs shall be equivalent to those specified in EPA Method 25B or as specified in § 139.4(5).(4) For determining the magnitude of VOC leaks from petroleum refinery equipment, from synthetic organic chemical and polymer manufacturing equipment and from surface active agent manufacturing equipment, test methods and procedures shall be equivalent to those specified in EPA Method 21 or as specified in § 139.4(5). The owner or operator of a source may exclude methane and ethane from this measurement. If methane and ethane are excluded, the measurement of methane and ethane together shall be reported.(5) For determining the VOC leak tightness of truck tanks, test methods and procedures shall be equivalent to those specified in EPA Method 27 or as specified in § 139.4(5).(6) For determining the magnitude of VOC leaks from gasoline tank trucks and vapor collection systems, test methods and procedures shall be equivalent to those specified in EPA Method 21 or as specified in § 139.4(5).(7) Results shall be reported in accordance with the units specified in the appropriate section of Chapter 129.(8) Test methods for the determination of RVP in gasoline shall be in accordance with the procedures in 40 CFR Part 80 , Appendix E (relating to test for determining Reid vapor pressure (RVP) of gasoline and gasoline-oxygenate blends).The provisions of this § 139.14 adopted March 3, 1972, effective 3/20/1972, 2 Pa.B. 383; amended April 27, 1979, effective 8/1/1979, 9 Pa.B. 1447; corrected May 11, 1979, effective 8/1/1979, 9 Pa.B. 1534; amended June 19, 1981, effective 6/20/1981, 11 Pa.B. 2118; amended August 12, 1983, effective 8/13/1983, 13 Pa.B. 2478; amended August 24, 1984, effective 3/24/1984, 14 Pa.B. 3090; amended May 6, 1988, effective 5/7/1988, 18 Pa.B. 2098; amended November 25, 1994, effective 11/26/1994, 24 Pa.B. 5899; amended October 31, 1997, effective 11/1/1997, 27 Pa.B. 5601; amended June 9, 2000, effective 6/10/2000, 30 Pa.B. 2995.
