Texas Administrative Code › Title 30 - ENVIRONMENTAL QUALITY › Part 1 - TEXAS COMMISSION ON ENVIRONMENTAL QUALITY › Chapter 115 - CONTROL OF AIR POLLUTION FROM VOLATILE ORGANIC › Subchapter B - GENERAL VOLATILE ORGANIC COMPOUND SOURCES › Division 4 - INDUSTRIAL WASTEWATER › Section 115.147 - Exemptions

Current through Reg. 49, No. 28; July 12, 2024
The following exemptions apply in the Beaumont/Port
						Arthur, Dallas/Fort Worth, El Paso, and Houston/Galveston areas.
(1) Any plant with an annual volatile organic
					 compounds (VOC) loading in wastewater, as determined in accordance with §
											115.148
					 of this title (relating to Determination of Wastewater Characteristics), less
					 than or equal to ten megagrams (Mg) (11.03 tons) is exempt from the control
					 requirements of §
											115.142 of
					 this title (relating to Control Requirements).
(2) At any plant with an annual VOC loading
					 in wastewater, as determined in accordance with §
											115.148
					 of this title greater than ten Mg (11.03 tons), any person who is the owner or
					 operator of the plant may exempt from the control requirements of §
											115.142 of
					 this title one or more affected VOC wastewater streams for which the sum of the
					 annual VOC loading in wastewater for all of the exempted streams is less than
					 or equal to ten Mg (11.03 tons).
(3) Unless specifically required by this
					 division (relating to Industrial Wastewater), any piece of equipment of a
					 wastewater storage, handling, transfer, or treatment facility to which the
					 control requirements of §
											115.142 of
					 this title apply is exempt from the requirements of any other division of this
					 chapter. This paragraph does not apply to pieces of equipment or components
					 which are subject to the requirements of Subchapter D, Division 3, and/or
					 Subchapter H of this chapter (relating to Fugitive Emission Control in
					 Petroleum Refining, Natural Gas/Gasoline Processing, and Petrochemical
					 Processes in Ozone Nonattainment Areas; and Highly-Reactive Volatile Organic
					 Compounds).
(4) If compliance with
					 the control requirements of §
											115.142 of
					 this title would create a safety hazard in a component of a wastewater storage,
					 handling, transfer, or treatment facility, the owner or operator may request
					 the executive director to exempt that component from the control requirements
					 of §
											115.142 of
					 this title. The executive director shall approve the request if justified by
					 the likelihood and magnitude of the potential injury and if the executive
					 director determines that reducing or eliminating the hazard is technologically
					 or economically unreasonable based on the emissions reductions that would be
					 achieved.
(5) Wet weather retention
					 basins are exempt from the requirements of this division.
(6) Petroleum refineries in the Beaumont/Port
					 Arthur area are exempt from the requirements of this division.
(7) The following exemptions apply to
					 petroleum refineries in the Houston/Galveston area.
(A) Petroleum refineries are exempt from the
					 requirement in §
												115.142 of
					 this title that after December 31, 2002, the control requirements apply from
					 the point of generation of an affected VOC wastewater stream until the affected
					 VOC wastewater stream is either returned to a process unit, or is treated to
					 reduce the VOC content of the wastewater stream by 90% by weight and also
					 reduce the VOC content of the same VOC wastewater stream to less than 1,000
					 parts per million by weight, provided that petroleum refineries continue to
					 apply the requirement in §
												115.142 of
					 this title that the control requirements apply from the point of generation of
					 an affected VOC wastewater stream until the affected VOC wastewater stream is
					 either returned to a process unit, or is treated to remove VOC so that the
					 wastewater stream no longer meets the definition of an affected VOC wastewater
					 stream.
(B) Junction boxes are
					 exempt from the requirements of §
												115.142(1)(D)(ii)
					 of this title, provided that after December 31, 2002 they continue to comply
					 with the requirements of §
												115.142(1)(D)(i)
					 of this title.
(C) Properly
					 operated biotreatment units are exempt from the requirements of
					 §§115.142(3), 115.144(4), and 115.145(7) and (8) of this title
					 (relating to Control Requirements; Inspection and Monitoring Requirements; and
					 Approved Test Methods).
