Current through Vol. 24-12, July 15, 2024
Rule 602.
(1)
				  Beginning April 1, 2016, a community or noncommunity water supply is in
				  compliance with the MCL for E. coli for samples taken under R 325.10704a to R
				  325.10704k unless 1 or more of the following conditions occur:
(a) The supply has an E. coli-positive repeat
				  sample following a total coliform-positive routine sample.
(b) The supply has a total coliform-positive
				  repeat sample following an E. coli-positive routine sample.
(c) The supply fails to take all required
				  repeat samples following an E. coli-positive routine sample.
(d) The supply fails to test for E. coli when
				  a repeat sample tests positive for total coliform.
Note to this subrule: For purposes of the public
					 notification requirements in
					 R 325.10401a to
					 R 325.10409, violation of the MCL
					 may pose an acute risk to health.
Michigan Administrative Code › Department - Environmental Quality › Drinking Water And Municipal Assistance Division › Supplying Water to the Public › Part 6 - STATE DRINKING WATER STANDARDS AND ANALYTICAL › Section R. 325.10603 - Radionuclides; MCLs; applicability

Current through Vol. 24-12, July 15, 2024
Rule 603.
(1)
				  Community water supplies, also known as "supplies" in this rule and R
				  325.10604, shall comply with the MCLs in this rule and compliance shall be
				  determined under R 325.10604.
(2)
				  The MCLs for radionuclides are all of the following:
(a) The maximum contaminant level for
				  combined radium 226 and radium 228 is 5 picoCurries per liter (pCi/l). The
				  combined radium-226 and radium-228 value is determined by the addition of the
				  results of the analysis for radium-226 and the analysis for
				  radium-228.
(b) The maximum
				  contaminant level for gross alpha particle activity, including radium 226, but
				  excluding radon and uranium, is 15 pCi per liter.
(c) Both of the following apply to the MCL
				  for beta particle and photon radioactivity:
(i) The average annual concentration of beta
				  particle and photon radioactivity from man-made radionuclides in drinking water
				  shall not produce an annual dose equivalent to the total body or any internal
				  organ greater than 4 millirems per year.
(ii) Except for the radionuclides listed in
				  table 1 of this rule, the concentration of man-made radionuclides causing 4
				  millirems total body or organ dose equivalents shall be calculated on the basis
				  of a 2-liter-per-day drinking water intake using the 168-hour data listed in
				  the publication entitled "maximum permissible body burdens and maximum
				  permissible concentration of radionuclides in air or water for occupational
				  exposure," nbs (national bureau of standards) handbook 69, as amended August,
				  1963, United States department of commerce, which is adopted by reference in R
				  325.10112. If 2 or more radionuclides are present, then the sum of their annual
				  dose equivalent to the total body or to any organ shall not be more than 4
				  millirem per year. Table 1 Average Annual Concentrations Assumed to Produce a
				  Total Body or Organ Dose of 4 Millirem Per Year Radionuclide Critical organ pCi
				  per liter Tritium Total body 20,000 Strontium-90 Bone marrow 8
(d) The maximum contaminant level
				  for uranium is 30 micrograms per liter (ug/l).

Current through Vol. 24-12, July 15, 2024
Rule 604.
(1)
				  Compliance with R 325.10603 shall be determined based on the analytical result
				  or results obtained at each sampling point. If 1 sampling point is in violation
				  of an MCL, then the supply is in violation of the MCL. All of the following
				  provisions apply:
(a) For supplies monitoring
				  more than once per year, compliance with the MCL is determined by a running
				  annual average at each sampling point. If the average of any sampling point is
				  greater than the MCL, then the supply is out of compliance with the
				  MCL.
(b) For supplies monitoring
				  more than once per year, if any sample result causes the running average to
				  exceed the MCL at any sample point, then the supply is out of compliance with
				  the MCL immediately.
(c) Supplies
				  shall include all samples taken and analyzed under this rule, R 325.10603, R
				  325.10725, R 325.10726, R 325.10728, R 325.10729, and R 325.10730 in
				  determining compliance, even if that number is greater than the minimum
				  required.
(d) If a supply does not
				  collect all required samples when compliance is based on a running annual
				  average of quarterly samples, then compliance shall be based on the running
				  average of the samples collected.
(e) If a sample result is less than the
				  detection limit, then zero shall be used to calculate the annual average,
				  unless a gross alpha particle activity is being used instead of radium-226, or
				  uranium, or both. If the gross alpha particle activity result is less than the
				  detection limit, then half the detection limit shall be used to calculate the
				  annual average.

(2) Compliance with the MCLs in table 1 of
				  this rule shall be determined based on the analytical results obtained at each
				  sampling point. If 1 sampling point is in violation of the MCL, then the supply
				  is in violation of the MCL. All of the following provisions apply:
(a) For supplies monitoring more than once
				  per year, compliance with the MCL is determined by a running annual average at
				  each sampling point.
(b) Supplies
				  monitoring annually or less frequently whose sample result exceeds the MCL
				  shall begin quarterly sampling. Compliance with the MCL shall be based on the
				  running annual average. For the purpose of calculating the running annual
				  average, the initial exceedance shall be considered the result for the first
				  quarter. If the department requires a confirmation sample under R
				  325.10716(15), then the average of the initial exceedance and the confirmation
				  sample shall be considered the result for the first quarter.The supply shall
				  not be considered in violation of the MCL until it has completed 1 year of
				  quarterly sampling.
(c) If any
				  sample result causes the running annual average to exceed the MCL at any
				  sampling point, then the supply is out of compliance with the MCL
				  immediately.
(d) If a supply fails
				  to collect the required number of samples, then compliance shall be based on
				  the total number of samples collected.
(e) If a sample result is less than the
				  detection limit, then zero shall be used to calculate the annual
				  average.

					 not more than 0.05% acrylamide dosed at 1 part per million, or equivalent, and
					 not more than 0.01% epichlorohydrin dosed at 20 parts per million, or
					 equivalent. This rule establishes treatment techniques for acrylamide and
					 epichlorohydrin in place of maximum contaminant levels.
