South Carolina Code of Regulations › Chapter 61 - DEPARTMENT OF HEALTH AND ENVIRONMENTAL CONTROL › Subchapter 61-58.11 - Control of Lead and Copper › Section 61-58.11.L - Reporting Requirements

Current through Register Vol. 48, No. 6, June 28, 2024
All water systems shall report all of the following information
				to the Department in accordance with this section.
(1) Reporting requirements for tap water
			 monitoring for lead and copper and for water quality parameter monitoring.
(a) Notwithstanding the requirements of
			 R.61-58.6.B(1),
			 except as provided in paragraph (1)(a)(viii) of this section a water system
			 must report the information specified in paragraphs (1)(a)(i) through (ix) of
			 this section for all tap water samples specified in R.61-58.11.H and for all water
			 quality parameter samples specified in R.61-58.11.I within the first ten
			 (10) days following the end of each applicable tap sampling monitoring period
			 specified in R.61-58.11.H and
			 R.61-58.11.I (i.e., every six (6)
			 months, annually, every three (3) years, or every nine (9) years). For tap
			 sampling periods with a duration less than six (6) months, the end of the tap
			 sampling monitoring period is the last date samples can be collected during
			 that tap sampling period as specified in R.61-58.11.H and R.61-58.11.I.
(i) The results of all tap samples for lead
			 and copper including the location of each site and the site selection criteria
			 under R.61-58.11.H(1)(c) through
			 (j), used as the basis for which the site was
			 selected for the water system's sampling pool, accounting for R.61-58.11.H(1)(k);
(ii) Documentation for each tap water lead or
			 copper sample for which the water system requests invalidation pursuant to
			 R.61-58.11.H(5)(b)
			 above;
(iii) Water systems with
			 lead service lines, galvanized service lines requiring replacement, or lead
			 status unknown service lines in the lead service line inventory conducted under
			 R.61-58.11.F(1)
			 must re-evaluate the tap sampling locations used in their sampling pool prior
			 to the compliance date specified in R.61-58.11.B(1) and
			 thereafter prior to the next round of tap sampling conducted by the system, or
			 annually, whichever is more frequent.
(A) By
			 the start of the first applicable tap sampling monitoring period in
			 R.61-58.11.H(4),
			 the water system must submit a site sample plan to the Department in accordance
			 with R.61-58.11.H, including a list of
			 tap sample site locations identified from the inventory in R.61-58.11.F(1),
			 and a list of tap sampling water quality parameter (WQP) sites selected under
			 R.61-58.11.I(1)(a). The site sample
			 plan must be updated and submitted to the Department prior to any changes to
			 sample site locations. The Department may require modifications to the site
			 sample plan as necessary.
(B) For
			 water systems with lead service lines with insufficient lead service line sites
			 to meet the minimum number required in R.61-58.11.H, documentation in
			 support of the conclusion that there are an insufficient number of lead service
			 line sites meeting the criteria under R.61-58.11.H(1)(c) or
			 (d) for community water systems or
			 R.61-58.11.H(1)(h)
			 for non-transient, non-community water systems, as
			 applicable;
(iv) The 90th
			 percentile lead and copper concentrations measured from among all lead and
			 copper tap water samples collected during each tap sampling period (calculated
			 in accordance with R.61-58.11.B(3)(d),
			 unless the State calculates the water system's 90th percentile lead and copper
			 levels under paragraph (8) of this section;
(v) With the exception of initial tap
			 sampling conducted pursuant to R.61-58.11.H(4)(a)(i),
			 the water system must identify any site which was not sampled during previous
			 tap sampling periods, and include an explanation of why sampling sites have
			 changed;
(vi) The results of all
			 water quality parameter tap samples that are required to be collected under
			 R.61-58.11.I(2) through
			 (7);
(vii) The results of all samples collected at
			 the entry point(s) to the distribution system for applicable water quality
			 parameters under R.61-58.11.I(2) through
			 (5);
(viii) A water system shall report the
			 results of all water quality parameter samples collected under Section I(3) -
			 (6) above, during each six (6)-month monitoring period specified in Section
			 I(4) above, within the first ten (10) days following the end of the monitoring
			 period unless the Department has specified a more frequent reporting
			 requirement . ; and
(ix) By the
			 start of the first applicable tap sampling period in R.61-58.11.H(4),
			 the water system must submit to the Department a copy of the tap sampling
			 protocol that is provided to individuals who are sampling. The Department shall
			 verify that wide-mouth collection bottles are used and recommendations for
			 pre-stagnation flushing and aerator cleaning or removal prior to sample
			 collection are not included pursuant to R.61-58.11.H(2).
			 The tap sampling protocol shall contain instructions for correctly collecting a
			 first-draw sample for sites without lead service lines and a first-draw and a
			 fifth liter sample for sites with lead service lines, where applicable. If the
			 water system seeks to modify its tap sampling protocol specified in this
			 paragraph (1)(a)(ix), it must submit the updated version of the protocol to the
			 Department for review and approval no later than sixty (60) days prior to
			 use.
