Section 115.137 - Exemptions(a) For the Beaumont/Port Arthur, Dallas/Fort Worth, El Paso, and Houston/Galveston areas, the following exemptions shall apply. (1) Any volatile organic compound (VOC) water separator used exclusively in conjunction with the production of crude oil or condensate is exempt from § 115.132(a) of this title (relating to Control Requirements) if the emissions from the separator have a combined weight of VOC equal to or less than 100 pounds (45.4 kg) in any continuous 24-hour period. When emissions from multiple sources (including, but not limited to, VOC water separators, treaters, storage tanks, and saltwater disposal tanks) are routed through a common vent, the calculation of VOC emissions for purposes of this exemption shall be based upon the total of all emission sources which are routed to the common vent. It is unacceptable to disconnect any of the multiple sources routed through a common vent for purposes of complying with this exemption.(2) Any single or multiple compartment VOC water separator which separates materials having a true vapor pressure of VOC less than 0.5 pounds per square inch absolute (psia) (3.4 kPa) obtained from any equipment is exempt from § 115.132(a) of this title.(3) Any single or multiple compartment VOC water separator which is designed solely to capture stormwater, spills, or exterior surface cleanup waters is exempt from this division (relating to Water Separation), provided that the separator is fully covered. These separators are not required to be equipped with pressure/vacuum vents or vapor control systems.(b) For Gregg, Nueces, and Victoria Counties, the following exemptions shall apply. (1) VOC water separators used exclusively in conjunction with the production of crude oil or condensate are exempt from § 115.132(b) of this title.(2) Any single or multiple compartment VOC water separator which separates less than 200 gallons (757 liters) a day of materials containing VOC obtained from any equipment is exempt from § 115.132(b) of this title.(3) Any single or multiple compartment VOC water separator which separates materials having a true vapor pressure of VOC less than 1.5 psia (10.3 kPa) obtained from any equipment is exempt from § 115.132(b) of this title.(4) In Gregg County, any single or multiple compartment VOC water separator which separates materials obtained from any equipment in a facility other than a petroleum refinery is exempt from § 115.132(b) of this title.(5) Any single or multiple compartment VOC water separator which is designed solely to capture stormwater, spills, or exterior surface cleanup waters is exempt from this division, provided that the separator is fully covered. These separators are not required to be equipped with pressure/vacuum vents or vapor control systems.(c) For Aransas, Bexar, Calhoun, Matagorda, San Patricio, and Travis Counties, the following exemptions shall apply.(1) VOC water separators used exclusively in conjunction with the production of crude oil or condensate are exempt from § 115.132(c) of this title.(2) Any single or multiple compartment VOC water separator which separates less than 200 gallons (757 liters) a day of materials containing VOC obtained from any equipment is exempt from § 115.132(c) of this title.(3) Any single or multiple compartment VOC water separator which separates materials having a true vapor pressure of VOC less than 1.5 psia (10.3 kPa) obtained from any equipment is exempt from § 115.132(c) of this title.(4) Any single or multiple compartment VOC water separator which is designed solely to capture stormwater, spills, or exterior surface cleanup waters is exempt from this division, provided that the separator is fully covered. These separators are not required to be equipped with pressure/vacuum vents or vapor control systems.30 Tex. Admin. Code § 115.137
