Current through Register Vol. 51, No. 14, July 12, 2024
A. The Approving
				  Authority may grant to a supplier of water a variance or variances from certain
				  requirements of this chapter. The requirements for obtaining variances are as
				  follows:
(1) The Approving Authority may
				  issue a variance based on the condition that the supplier of water installs the
				  best technology, treatment techniques, or other means, which the Approving
				  Authority finds are available when taking costs into consideration, and based
				  upon an evaluation that indicates that alternative sources of water are not
				  reasonably available;
(2) The
				  Approving Authority may issue a variance to a supplier of water after
				  documentation and consideration of findings set in
				  40 CFR §
												142.20;
(3) The Approving Authority may issue to
				  systems serving fewer than 10,000 persons a variance from a maximum contaminant
				  level, or a treatment technique in accordance with 40 CFR §§ 142.301 -142.313,
				  Subpart K, except for microbial contaminants that are included in subparts H,
				  P, S, T, W, and Y of the 40 CFR § 141 .
(4) Variances from the treatment technique
				  requirements of 40 CFR § 141, Subpart H, may not be granted;
(5) Variances from the total coliform and E.
				  coli maximum contamination levels may not be granted; beginning April 1, 2016
				  the total coliform maximum contaminant level is no longer effective;
(6) Variances from a maximum contaminant
				  level for any synthetic organic chemical may only be granted if the:
(a) Conditions of §A(4) of this regulation
				  are met; and
(b) Requirements of
				  Regulation .03-1 of this chapter are met;
(7) Except as otherwise provided in this
				  regulation, variances from a maximum contaminant level may be granted if the
				  Approving Authority finds that:
(a)
				  Characteristics of the raw water sources (which are reasonably available to the
				  system) are such that the system cannot meet the requirements respecting the
				  maximum contaminant levels of this regulation when application has been made of
				  the best technology, treatment techniques, or other means, which the Approving
				  Authority finds are generally available, taking costs into consideration;
				  and
(b) The granting of a variance
				  does not result in an unreasonable risk to the health of persons served by the
				  system;
(8) Variances
				  for a treatment technique other than treatment technique requirements of 40 CFR
				  § 141, Subpart H, may be granted if the Approving Authority finds that the
				  supplier of water applying for the variance has demonstrated that the treatment
				  technique is not necessary to protect the health of persons because of the
				  nature of the raw water source of the system.

				  water that collects 40 or more samples a month;
(2) Two or more samples collected in any
				  month are positive for total coliform for any supplier of water that collects
				  less than 40 samples a month;
(3) A
				  total coliform repeat sample is positive following a fecal coliform-positive or
				  E. coli-positive routine sample; or
(4) Any repeat sample is positive for fecal

Current through Register Vol. 51, No. 14, July 12, 2024
A. A supplier of water using a surface water
				  source or a ground water source under the direct influence of surface water
				  shall perform turbidity monitoring as required by
				  40 CFR §§
											141.70-
				  141.75.
B. Filtered and unfiltered public water

				  regulation until June 29, 1993. A supplier of water using unfiltered surface
				  water or ground water under the direct influence of surface water, which is
				  required by the Approving Authority to filter, but which has not installed
				  filtration, shall continue to comply with §§C and D of this regulation until
				  filtration is installed, even beyond June 29, 1993.
C. The supplier of water shall take samples
				  at a representative entry point to the water distribution system at least once

				  compliance with Regulation .08 of this chapter.
D. If a measurement indicates the maximum
				  allowable limit has been exceeded, the sampling and measurements shall be
				  repeated, preferably in 1 hour. If the repeat sample confirms that the maximum
				  allowable limit has been exceeded, the supplier of water shall report to the
				  Approving Authority as directed in Regulation .19 of this chapter. If the
				  results of the repeat sample are less than the first sample, the second value
				  should be used in the calculation of the monthly average; otherwise, repeat
				  samples may not be used in calculating the monthly average. If the monthly
				  average of the daily samples exceeds the maximum allowable limit, or if the
				  average of two samples taken on consecutive days exceeds 5 TU, the supplier of
				  water shall notify the Approving Authority as directed in Regulation .19 of
				  this chapter and shall notify the public as directed in Regulation .20 of this
				  chapter.
E. Measurements of
				  turbidity shall be made by the Nephelometric Method in accordance with the
				  methods specified in 40 CFR
				  §

				  turbidity monitoring may be used by a supplier of water only with approval by
				  the Approving Authority.
F.
				  Suppliers of water at systems serving 10,000 or more individuals shall meet the
				  turbidity monitoring requirements in
				  40 CFR §
											141.173(a) in addition to
				  the requirements of §§A-E of this regulation.
G. Suppliers of water at systems serving
				  fewer than 10,000 individuals shall meet the turbidity monitoring requirements
				  in 40 CFR §§

Current through Register Vol. 51, No. 14, July 12, 2024
A. This
				  regulation applies to a community water system (CWS). A CWS, both surface and
				  ground water, designated by the Approving Authority as vulnerable shall sample
				  for beta particle and photon radioactivity.
B. Monitoring.
(1) Suppliers of water shall collect
				  quarterly samples for beta emitters and annual samples for tritium and
				  strontium-90 at each entry point to the distribution system, after this called
				  a sampling point, beginning within the next calendar quarter after being
				  notified by the Approving Authority.
(2) Suppliers of water at systems already
				  designated as vulnerable by the Approving Authority shall continue to sample
				  until the Approving Authority reviews and either reaffirms or removes the
				  designation.
(3) If the gross beta
				  particle activity minus the naturally occurring potassium-40 beta particle
				  activity at a sampling point has a running annual average (computed quarterly)
				  less than or equal to 50 picocuries per liter (pCi/l) (screening level), the
				  Approving Authority may reduce the frequency of monitoring at that sampling
				  point to once every 3 years.

Current through Register Vol. 51, No. 14, July 12, 2024
A. This regulation
				  applies to a community water system (CWS). The Approving Authority may require
				  more frequent monitoring than specified in Regulations .13 and .13-1 of this
				  chapter, or may require confirmation samples at its discretion. The results of
				  the initial and confirmation samples shall be averaged for use in compliance
				  determinations.
B. Suppliers of
				  water shall monitor at the time designated by the Approving Authority during
				  each compliance period.
C.
				  Compliance with Regulation .09 of this chapter shall be determined based on the
				  analytical results obtained at each sampling point. If one sampling point is in
				  violation of an MCL, the system is in violation of the MCL.
D. For a CWS monitoring more than once per
				  year:
(1) Compliance with the MCL is
				  determined by a running annual average at each sampling point;
(2) If the average of any sampling point is
				  greater than the MCL, the system is out of compliance with the MCL;
				  and
(3) If any sample result causes
				  the running average to exceed the MCL at any sample point, the system is out of
				  compliance with the MCL immediately.
