			 arsenic above 0.005 mg/L and up to and including 0.01 mg/L:
(a) Shall include in its report a short
			 informational statement about arsenic, using language such as: While your
			 drinking water meets State and Federal standards for arsenic, it does contain
			 low levels of arsenic. The Federal standard balances the current understanding
			 of arsenic's possible health effects against the cost of removing arsenic from
			 drinking water. EPA continues to research health effects of low levels of
			 arsenic, which is a mineral known to cause cancer in humans at high
			 concentrations and is linked to other health effects such as skin damage and
			 circulatory problems.
(b) May write
			 its own educational statement, but only in consultation with the
			 Department.

South Carolina Code of Regulations › Chapter 61 - DEPARTMENT OF HEALTH AND ENVIRONMENTAL CONTROL › Subchapter 61-58.15 - Stage 2 Disinfection Byproducts Requirements › Section 61-58.15.G - Conditions Requiring Increased Monitoring

Current through Register Vol. 48, No. 6, June 28, 2024
(1) If a system is required to monitor at a
			 particular location annually or less frequently than annually under
			 R.61-58.15.C or
			 R.61-58.15.E, they must increase monitoring to dual sample sets once per
			 quarter (taken every 90 days) at all locations if a TTHM sample is greater than
			 0.080 mg/L or a HAA5 sample is greater than 0.060 mg/L at any
			 location.
(2) A system is in
			 violation of the MCL when the LRAA exceeds the R.61-58.15 MCLs in
			 R.61-58.5.P,
			 calculated based on four consecutive quarters of monitoring (or the LRAA
			 calculated based on fewer than four quarters of data if the MCL would be
			 exceeded regardless of the monitoring results of subsequent quarters). A system
			 is in violation of the monitoring requirements for each quarter that a
			 monitoring result would be used in calculating an LRAA if they fail to
			 monitor.
(3) A system may return to
			 routine monitoring once they have conducted increased monitoring for at least
			 four consecutive quarters and the LRAA for every monitoring location is less
			 than or equal to 0.060 mg/L for TTHM and less than or equal to 0.045 mg/L for
			 HAA5.
South Carolina Code of Regulations › Chapter 61 - DEPARTMENT OF HEALTH AND ENVIRONMENTAL CONTROL › Subchapter 61-58.15 - Stage 2 Disinfection Byproducts Requirements › Section 61-58.15.H - Operational Evaluation Levels

Current through Register Vol. 48, No. 6, June 28, 2024
(1) A system has exceeded the operational
			 evaluation level at any monitoring location where the sum of the two previous
			 quarters' TTHM results plus twice the current quarter's TTHM result, divided by
			 4 to determine an average, exceeds 0.080 mg/L, or where the sum of the two
			 previous quarters' HAA5 results plus twice the current quarter's HAA5 result,
			 divided by 4 to determine an average, exceeds 0.060 mg/L.
(2) Operational Evaluations
(a) If a system exceeds the operational
			 evaluation level, they must conduct an operational evaluation and submit a
			 written report of the evaluation to the Department no later than 90 days after
			 being notified of the analytical result that causes them to exceed the
			 operational evaluation level. The written report must be made available to the
			 public upon request.
(b) The
			 operational evaluation must include an examination of system treatment and
			 distribution operational practices, including storage tank operations, excess
			 storage capacity, distribution system flushing, changes in sources or source
			 water quality, and treatment changes or problems that may contribute to TTHM
			 and HAA5 formation and what steps could be considered to minimize future
			 exceedences.
(i) A system may request and the
			 Department may allow them to limit the scope of their evaluation if they are
			 able to identify the cause of the operational evaluation level
			 exceedance.
(ii) A request to limit
			 the scope of the evaluation does not extend the schedule in paragraph (2)(a) of
			 this section for submitting the written report. The Department must approve
			 this limited scope of evaluation in writing and the system must keep that
			 approval with the completed report.

				plus they meet the reduced monitoring criteria in R.61-58.15.E(1),
				and they do not change or add monitoring locations from those used for
				compliance monitoring under R.61-58.13. If the system's
				monitoring locations under this part R.61-58.15 differ from the
				monitoring locations under R.61-58.13, the system may not
				remain on reduced monitoring after the dates identified R.61-58.15.B
				for compliance with this part R.61-58.15.

(1) Reporting
(a) Systems must report the following
			 information for each monitoring location to the Department within 10 days of
			 the end of any quarter in which monitoring is required:
(i) Number of samples taken during the last
			 quarter.
(ii) Date and results of
			 each sample taken during the last quarter.
(iii) Arithmetic average of quarterly results
			 for the last four quarters for each monitoring location (LRAA), beginning at
			 the end of the fourth calendar quarter that follows the compliance date and at
			 the end of each subsequent quarter. If the LRAA calculated based on fewer than
			 four quarters of data would cause the MCL to be exceeded regardless of the
			 monitoring results of subsequent quarters, the system must report this
			 information to the Department as part of the first report due following the
			 compliance date or anytime thereafter that this determination is made. If a
			 system is required to conduct monitoring at a frequency that is less than
			 quarterly, they must make compliance calculations beginning with the first
			 compliance sample taken after the compliance date, unless they are required to
			 conduct increased monitoring under R.61-58.15.G.
(iv) Whether, based on R.61-58.5.P(2)(b)
			 and this part R.61-58.15, the MCL was
			 violated at any monitoring location.
(v) Any operational evaluation levels that
			 were exceeded during the quarter and, if so, the location and date, and the
			 calculated TTHM and HAA5 levels.
