South Carolina Code of Regulations › Chapter 61 - DEPARTMENT OF HEALTH AND ENVIRONMENTAL CONTROL › Subchapter 61-58.16 - Ground Water Rule › Section 61-58.16.F - Treatment Technique Requirements For Ground Water Systems

Current through Register Vol. 48, No. 6, June 28, 2024
(1) Ground water
			 systems with significant deficiencies or source water fecal contamination.
(a) The treatment technique requirements of
			 R.61-58.16.F must be met by ground water systems when a significant deficiency
			 is identified or when a ground water source sample collected under
			 R.61-58.16.E(1)(c)
			 is fecal indicator positive.
(b) If
			 directed by the Department, a ground water system with a ground water source
			 sample collected under R.61-58.16.E(1)(b),
			 R.61-58.16.E(1)(d), or R.61-58.16.E(2) that is fecal indicator positive must
			 comply with the treatment technique requirements of R.61-58.16.F.
(c) When a significant deficiency is
			 identified at a Subpart H public water system that uses both ground water and
			 surface water or GWUDI, the system must comply with R.61-58.16.F except in
			 cases where the Department determines that the significant deficiency is in a
			 portion of the distribution system that is served solely by surface water or
			 GWUDI.
(d) Unless the Department
			 directs the ground water system to implement a specific corrective action, the
			 ground water system must consult with the Department regarding the appropriate
			 corrective action within 30 days of receiving written notice from the
			 Department of a significant deficiency, written notice from a laboratory that a
			 ground water source sample collected under R.61-58.16.E(1)(c)
			 was found to be fecal indicator positive, or direction from the Department that
			 a fecal indicator positive sample collected under R.61-58.16.E(1)(b),
			 R.61-58.16.E(1)(d), or R.61-58.16.E(2) requires corrective action. For the
			 purposes of R.61-58.16, significant deficiencies include, but are not limited
			 to, defects in design, operation, or maintenance, or a failure or malfunction
			 of the sources, treatment, storage, or distribution system that the Department
			 determines to be causing, or have the potential for causing, the introduction
			 of contamination into the water delivered to consumers.
(e) Within 120 days, or earlier if directed
			 by the Department, of receiving written notification from the Department of a
			 significant deficiency, written notice from a laboratory that a ground water
			 source sample collected under R.61-58.16.E. (1)(c) was found to be fecal
			 indicator positive, or direction from the Department that a fecal indicator
			 positive sample collected under R.61-58.16.E(1)(b),
			 R.61-58.16.E(1)(d), or R.61-58.16.E(2) requires corrective action, the ground
			 water system must either:
(i) Have completed
			 corrective action in accordance with applicable Department plan review
			 processes or other Department guidance or direction, if any, including
			 Department-specified interim measures; or
(ii) Be in compliance with a
			 Department-approved corrective action plan and schedule subject to the
			 following conditions:
(A) Any subsequent
			 modifications to a Department-approved corrective action plan and schedule must
			 also be approved by the Department.
(B) If the Department specifies interim
			 measures for the protection of public health pending Department approval of the
			 corrective action plan and schedule or pending completion of the corrective
			 action plan, the system must comply with these interim measures as well as with
			 any schedule specified by the Department.
(f) Corrective action alternatives. Ground
			 water systems that meet the conditions of R.61-58.16.F(1)(a) or (b) must
			 implement one or more of the following corrective action alternatives:
(i) Correct all significant
			 deficiencies.
(ii) Provide an
			 alternate source of water.
(iii)
			 Eliminate the source of contamination.
(iv) Provide treatment that reliably achieves
			 at least 4-log treatment of viruses (using inactivation, removal, or a
			 Department-approved combination of 4-log virus inactivation and removal) before
			 or at the first customer for the ground water source.
(g) Special notice to the public of
			 significant deficiencies or source water fecal contamination.
(i) In addition to the applicable public
			 notification requirements of R.61-58.6.E(2),
			 a community ground water system that receives notice from the Department of a
			 significant deficiency or notification of a fecal indicator positive ground
			 water source sample that is not invalidated by the Department must inform the
			 public served by the water system under R.61-58.12.C(11)(f)
			 of the fecal indicator positive source sample or of any significant deficiency
			 that has not been corrected. The system must continue to inform the public
			 annually until the significant deficiency is corrected or the fecal
			 contamination in the ground water source is determined by the Department to be
			 corrected under R.61-58.16.F(1)(e).
(ii) In addition to the applicable public
			 notification requirements of R.61-58.6.E(2),
			 a non-community ground water system that receives notice from the Department of
			 a significant deficiency must inform the public served by the water system in a
			 manner approved by the Department of any significant deficiency that has not
			 been corrected within 12 months of being notified by the Department, or earlier
			 if directed by the Department. The system must continue to inform the public
			 annually until the significant deficiency is corrected. The information must
			 include:
(A) The nature of the significant
			 deficiency and the date the significant deficiency was identified by the
			 Department.
(B) The
			 Department-approved plan and schedule for correction of the significant
			 deficiency, including interim measures, progress to date, and any interim
			 measures completed.
(C) For systems
			 with a large proportion of non-English speaking consumers, as determined by the
			 Department, information in the appropriate language(s) regarding the importance
			 of the notice or a telephone number or address where consumers may contact the
			 system to obtain a translated copy of the notice or assistance in the
			 appropriate language.
(iii) If directed by the Department, a
			 non-community water system with significant deficiencies that have been
			 corrected must inform its customers of the significant deficiencies, how the
			 deficiencies were corrected, and the dates of correction under
			 R.61-58.16.F(1)(g)(ii).
