Alabama Administrative Code › Title 335 - ALABAMA DEPARTMENT OF ENVIRONMENTAL MANAGEMENT › WATER DIVISION - WATER QUALITY PROGRAM › Chapter 335-6-15 - TECHNICAL STANDARDS, CORRECTIVE ACTION REQUIREMENTS AND FINANCIAL RESPONSIBILITY FOR OWNERS AND OPERATORS OF UNDERGROUND STORAGE TANKS › Section 335-6-15-.02 - Definitions

Current through Register Vol. 42, No. 9, June 28, 2024
The following words and terms, when used in this chapter,
				  shall have the following meanings unless the context clearly indicates
				  otherwise:
(a) "Aboveground release"
				means any release to the surface of the land or to surface water. This
				includes, but is not limited to, releases from the aboveground portion of an
				UST system and aboveground releases associated with overfills and transfer
				operations as the regulated substance moves to or from an UST system.
(b) "ADEM" means the Alabama Department of
				Environmental Management.
(c)
				"Airport hydrant fuel distribution system" means an UST system which fuels
				aircraft and operates under high pressure with large diameter underground
				piping that typically terminates into one or more hydrants (fill stands). The
				airport hydrant fuel distribution system begins where fuel enters one or more
				tanks from an external source such as a pipeline, barge, rail car, or other
				motor fuel carrier.
(d) "Ancillary
				equipment" means any devices including, but not limited to, such devices as
				underground piping, fittings, flanges, valves, and pumps used to distribute,
				meter, or control the flow of regulated substances to and from an
				UST.
(e) "Belowground release"
				means any release to the subsurface of the land, including releases to
				groundwater. This includes, but is not limited to, releases from the
				belowground portions of an underground storage tank system and belowground
				releases associated with overfills and transfer operations as the regulated
				substance moves to or from an underground storage tank.
(f) "Beneath the surface of the ground" means
				beneath the ground surface or otherwise covered with earthen
				materials.
(g) "Cathodic
				protection" is a technique to prevent corrosion of a metal surface by making
				that surface the cathode of an electrochemical cell. For example, an
				underground storage tank system can be cathodically protected through the
				application of either galvanic anodes or impressed current.
(h) "Cathodic protection tester" means a
				person who can demonstrate an understanding of the principles and measurements
				of all common types of cathodic protection systems as applied to buried or
				submerged metal piping and underground storage tank systems. At a minimum, such
				persons must have education and experience in soil resistivity, stray current,
				structure-to-soil potential, and component electrical isolation measurements of
				buried metal piping and underground storage tank systems. Such persons must
				also be certified, and then recertified every 3 years, as successfully
				completing in-class and field training from a corrosion expert. Certification
				may no longer be recognized by the Department and/or the certifying
				organization if a certified individual is not recertified within 90 days or
				another time period approved by the Department after expiration of their
				certification, there is evidence of fraud, or the tester is determined by the
				Department to not be capable of properly performing cathodic protection
				testing. At a minimum, certification training shall encompass all of the
				following and recertification training shall include the training outlined in
				subparagraphs (h)3. through 5. of this rule, or be in accordance with NACE
				International certification and recertification requirements:
1. Basics of corrosion which include the
				following discussions:
(i) What corrosion
				is;
(ii) Significance and costs of
				corrosion;
(iii) Conditions for
				corrosion to occur;
(iv)
				Electrochemical aspects of corrosion;
(v) Environmental effects on UST systems such
				as oxygen, temperature, corrosivity of the environment, concentration of
				corrosive element, and galvanic coupling;
(vi) Types of corrosion;
(vii) Galvanic series and Electromotive Force
				series; and
(viii) Corrosion
				properties of different metals and nonmetals.
