The following words and terms, when used in this subchapter, shall have the following meanings, unless the context clearly indicates otherwise.

1. (1) Action level--The concentration of constituents in the native soil or water at which corrective action will be required. Exceeding an action level warrants further assessment of the site, but does not mandate that site cleanup be required. Based upon the results of the site assessment, the need for site cleanup will then be determined and cleanup levels will be set. Action levels should not be used as cleanup levels; they are simply levels which signal the need for additional assessment.
2. (2) Adjacent landowner--A person who owns legal title to land which is within reasonably close proximity to property where a regulated underground storage tank (UST) or aboveground storage tank is located whether or not the land is contiguous to the property containing the tank.

4. (4) Commingled--See definition in §334.2 of this title (relating to Definitions).
5. (5) Confirmed--In the context of a release being confirmed by the agency under this subchapter, means that the executive director has determined that sufficient evidence exists to prove that a release of petroleum products has occurred from a petroleum storage tank subject to regulation under this chapter.
6. (6) Contract of subrogation--A document of agreement between the executive director and the eligible tank owner and operator which authorizes the executive director to recover costs reimbursed from persons who performed corrective action activities at leaking petroleum storage tank sites.
7.

9. (9) Eligible owner--Any person who meets the eligibility requirements prescribed in §334.310 of this title and who held or currently holds legal possession or ownership of an interest in a petroleum storage tank. For the purposes of this subchapter, if the actual ownership of the petroleum storage tank is uncertain, unknown, or in dispute, the fee simple owner of the surface estate of the tract on which the petroleum storage tank is located is considered the petroleum storage tank owner unless that person can demonstrate by appropriate documentation, including a deed reservation, invoice, bill of sale, or by other legally acceptable means that the petroleum storage tank is owned by another person. A person that has registered as an owner of a petroleum storage tank with the commission under §334.7 of this title (relating to Registration for Underground Storage Tanks (USTs) and UST Systems) (or a preceeding rule section concerning tank registration) after September 1, 1987, shall be considered the petroleum storage tank owner until such time as documentation demonstrates to the executive director's satisfaction that the legal interest in the petroleum storage tank was transfered to a different person subsequent to the date of the tank registration. This definition is subject to the limitations found in Texas Water Code, §26.3514, Limits on Liability of Lender; §26.3515, Limits on Liability of Corporate Fiduciary; and §25.3516, Limits on Liability of Taxing Unit.

12. (12) Initial abatement measures--The mitigation of all existing or potential fire, explosion, or vapor hazards, including the removal of phase-separated product, to provide adequate protection of human health, safety, and the environment in emergency situations or other situations where emergency actions must be implemented to prevent further impacts to the environment.
