Texas Administrative Code › Title 30 - ENVIRONMENTAL QUALITY › Part 1 - TEXAS COMMISSION ON ENVIRONMENTAL QUALITY › Chapter 214 - SECONDARY CONTAINMENT REQUIREMENTS FOR UNDERGROUND STORAGE TANK SYSTEMS LOCATED OVER CERTAIN AQUIFERS › Section 214.2 - Definitions

Current through Reg. 49, No. 28; July 12, 2024
The following words and terms, when used in this chapter,
				  shall have the following meanings and supercede the definitions in Chapter 334
				  of this title (relating to Underground and Aboveground Storage Tanks), unless
				  the context clearly indicates otherwise.
(1) Ancillary equipment -- Any devices that
				are used to distribute, meter, or control the flow of petroleum substances or
				hazardous substances into or out of an underground storage tank (UST),
				including, but not limited to, piping, fittings, flanges, valves, and
				pumps.
(2) Existing UST system -- A
				UST system which is used or designed to contain an accumulation of regulated
				substances for which installation either had commenced prior to December 22,
				1988, or had been completed on or prior to December 22, 1988. Installation will
				be considered to have commenced if the owner or operator had obtained all
				federal, state, and local approvals or permits necessary to begin physical
				construction at the site or installation of the tank system, and if either a
				continuous on-site physical construction or installation program had begun or
				the owner or operator had entered into contractual obligations (which could not
				be canceled or modified without substantial loss) which required that the
				physical construction at the site or installation of the tank system was to be
				completed within a reasonable time.
(3) Major aquifer -- An aquifer defined by
				the Texas Water Development Board (TWDB) as supplying large quantities of water
				in large areas of the state.
(4)
				New UST system -- A UST system which is used or designed to contain an
				accumulation of regulated substances for which installation commenced after
				December 22, 1988; or a UST system which is converted from the storage of
				materials other than regulated substances to the storage of regulated
				substances after December 22, 1988.
(5) Outcrop -- The surface extent of a major
				aquifer as mapped by the TWDB in which the host geologic formations are exposed
				at the land surface or overlain by alluvial or soil covers.
(6) Replaced -- The permanent removal from
				service (in accordance with all applicable requirements of Chapter 334 of this
				title) of a UST system and the installation of any replacement UST system in
				accordance with all applicable requirements of this chapter and Chapter 334 of
				this title.
(7) Secondary
				containment -- A method by which a secondary wall or barrier is installed
				around a UST system in a manner designed to prevent a release of a regulated
				substance from migrating beyond the secondary wall or barrier before the
				release can be detected. A secondary containment system may include an
				impervious liner, jacket, containment boot, sump, or vault surrounding a
				primary tank or piping system or a double-wall tank or piping system.
(8) Underground storage tank (UST) -- Any one
				or combination of underground tanks and any connecting underground pipes used
				to contain an accumulation of regulated substances, the volume of which,
				including the volume of the connecting underground pipes, is 10% or more
				beneath the surface of the ground.
(9) Underground storage tank (UST) system --
				A UST, connected underground piping, underground ancillary equipment, and
				containment system, if any.
(10)
				Upgraded --
(A) The addition, improvement,
				retrofitting, or renovation of an existing UST system with equipment or
				components as required to initially meet upgrading requirements with regard to
				corrosion protection, spill and overfill prevention, and release detection as
				specified in Chapter 334 of this title.
(B) The addition, improvement, retrofitting,
				or renovation of a new UST system with equipment or components as required to
				bring that system into initial compliance with the installation requirements
				which were:
(i) applicable after December 22,
				1988 and before September 29, 1989 under EPA rules (40 Code of Federal
				Regulations Part 280); or
(ii)
				applicable on or after September 29, 1989 under Chapter 334 of this
				title.
