South Carolina Code of Regulations › Chapter 61 - DEPARTMENT OF HEALTH AND ENVIRONMENTAL CONTROL › Subchapter 61-58 - State Primary Drinking Water Regulations › Section 61-58.B - Definitions

Current through Register Vol. 48, No. 6, June 28, 2024
(1) "Act" means the
			 State Safe Drinking Water Act of 1976, and amendments.
(2) "Action level" is the concentration of
			 lead or copper in water specified in R.61-58.11.B(1),
			 Lead and Copper Action Levels, which determines requirements under
			 R.61-58.11, Control of Lead and
			 Copper. The action for lead is 0.015 mg/L and the action level for copper is
			 1.3 mg/L.
(3) "Administrator" means
			 the Administrator of the United States Environmental Protection
			 Agency.
(4) "Aerator" means the
			 device embedded in the water faucet to enhance air flow with the water stream
			 and to prevent splashing.
(5)
			 "Annular space" means the space between the well casing and the formation or
			 the space between the inner casing and outer casing where two casings are
			 used.
(6) "Aquifer" means a
			 geologic formation, group of formations, or part of a formation that contains
			 sufficient saturated permeable material to yield significant quantities of
			 groundwater to wells and springs.
(7) "Aquifer Storage and Recovery (ASR) Well"
			 means a water well which allows potable water to be injected into a subsurface
			 aquifer to be recovered by pumping at a later date.
(8) "Artificial filter" means filter material
			 which is placed in the annular space to increase the effective diameter of the
			 well, and to prevent fine-grained sediments from entering the well.
(9) "Backflow prevention device" means any
			 device approved by the Department for use in preventing backflow under
			 prescribed limited conditions of use.
(10) "Bag filters" are pressure-driven
			 separation devices that remove particulate matter larger than 1 micrometer
			 using an engineered porous filtration media. They are typically constructed of
			 a non-rigid, fabric filtration media housed in a pressure vessel in which the
			 direction of flow is from the inside of the bag to outside.
(11) "Bank filtration" is a water treatment
			 process that uses a well to recover surface water that has naturally
			 infiltrated into ground water through a river bed or bank(s). Infiltration is
			 typically enhanced by the hydraulic gradient imposed by a nearby pumping water
			 supply or other well(s).
(12)
			 "Bedrock" means the parent solid rock formation underlying weathered rock and
			 soil.
(13) "Best available
			 technology" or "BAT" means the best technology, treatment techniques, or other
			 means which either the Department or the Environmental Protection Agency (EPA)
			 finds, after examination for efficacy under field conditions and not solely
			 under laboratory conditions, are available (taking cost into
			 consideration).
(14) "Board" means
			 the South Carolina Board of Health and Environmental Control charged with
			 responsibility for implementation of the Safe Drinking Water Act.
(15) "Boil Water Notice/Advisory" means a
			 notice, whether written or verbal, issued by the Department, or the owner or
			 operator of a public water system, notifying the users of the water system that
			 the water is/may be contaminated and to boil the water (vigorous rolling boil
			 for at least one minute) prior to using it for drinking or cooking. The notice
			 shall give the reason for its issuance and corrective actions being
			 taken.
(16) "Booster Pump" means
			 any pump installed within a water distribution system for the purpose of
			 increasing the water pressure in the water distribution system, including
			 distribution storage facilities downstream from the pump. The term booster pump
			 does not apply to the so called low service and high service pumps at water
			 treatment plants.
(17) "Business
			 Plan" for the purpose of these regulations means a document consisting of three
			 sub- plans, a "Facilities Plan", a "Management Plan", and a "Financing Plan"
			 which is intended to show how a water system will be self-sustaining and have
			 the commitment and the financial, managerial and technical capability to
			 consistently comply with the State Safe Drinking Water Act and these
			 Regulations.
(18) "Cartridge
			 filters" are pressure-driven separation devices that remove particulate matter
			 larger than 1 micrometer using an engineered porous filtration media. They are
			 typically constructed as rigid or semi-rigid, self-supporting filter elements
			 housed in pressure vessels in which flow is from the outside of the cartridge
			 to the inside.
(19) "Centralizer"
			 means device to keep the casing and screen aligned in the center of the
			 borehole to ensure proper emplacement of grout around the casing and artificial
			 filter around the screens.
(20)
			 "Certified Laboratory" means a laboratory approved by the Department under
			 Regulation
			 61- 81.
(21) "Certified Tester" means any person
			 holding an up-to-date backflow prevention assembly tester certification card
			 issued by the Department. Certified testers fall into one of the following
			 classifications:
(a) General Tester -any
			 person who has successfully completed an approved backflow prevention training
			 and certification course which is sponsored by or approved by the Department,
			 and who has personal possession of or whose employer owns a backflow prevention
			 assembly test kit. This person provides the service of testing backflow
			 prevention assemblies to the general public.
(b) Inspector Tester -any person with the
			 same qualifications as the General Tester, except the Inspector Tester must be
			 employed by a municipality, water district, subdivision, or other public water
			 system. The Inspector Tester is normally involved in the management of a
			 backflow prevention program, and does not sell his services to the general
			 public.
(c) Limited Tester -any
			 person with the same qualifications as the General Tester except the prescribed
			 test(s) is (are) conducted only on backflow prevention assemblies which are
			 owned by his employer. The Limited Tester does not provide testing services to
			 the general public.
(d)
			 Manufacturer's Agent -any person with the same qualifications as the General
			 Tester except the prescribed test(s) is (are) conducted as an extension of his
			 duties as a representative of a particular backflow prevention
			 company.
