(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) "Ancillary equipment" means any devices
				  including, but not limited to, such devices as piping, fittings, flanges,
				  valves, and pumps used to distribute, meter, or control the flow of regulated
				  substances to and from an UST.

(d) "Beneath the surface of the ground" means
				  beneath the ground surface or otherwise covered with earthen
				  materials.
(e) "Cathodic
				  protection" is a technique to prevent corrosion of a metal surface by making
				  that surface the cathode of an electrochemical cell. For example, a tank system
				  can be cathodically protected through the application of either galvanic anodes
				  or impressed current.
(f) "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 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 tank systems.
(g) "CERCLA" means the Comprehensive
				  Environmental Response, Compensation, and Liability Act of 1980, as
				  amended.
(h) "Class A operator"
				  means the individual who has primary responsibility to operate and maintain the

				  The Class B operator typically implements in-field aspects of operation,
				  maintenance, and associated recordkeeping for the UST system.
(j) "Class C operator" means the individual
				  responsible for initially addressing emergencies presented by a spill or
				  release from an UST system. The Class C operator typically controls or monitors
				  the dispensing or sale of regulated substances.
(k) "Coastal zone" means all coastal waters
				  and submerged lands seaward to the State's jurisdictional limits and all lands
				  and waters in the counties of the State which contain any one or more of the
				  critical areas. These counties are Beaufort, Berkeley, Charleston, Colleton,

(l) "Community Water System (CWS)" means a
				  public water system that serves at least 15 service connections used by
				  year-round residents of the area served by the system; or regularly serves at
				  least 25 year-round residents. The following are included as part of the
				  community water system:
(1) The wellhead for
				  groundwater and/or intake point(s) for surface water;
(2) Collection, treatment, storage, and
				  distribution facilities that are part of the community water system;
				  and
(3) The piping distribution
				  system that delivers the water to the community.
