Appendix A to R.61-58.6 -
				Endnotes
[Dagger] Until March 31, 2016
[Double Dagger] Beginning April 1,
				2016
1 Violations and other situations
				not listed in this table (e.g., failure to prepare Consumer Confidence
				Reports), do not require notice, unless otherwise determined by the Department.
				The Department may, at its option, also require a more stringent public notice
				tier (e.g., Tier 1 instead of Tier 2 or Tier 2 instead of Tier 3) for specific
				violations and situations listed in this Appendix, as authorized under
				R.61-58.6.E(2)(a) and
				(3)(a).
2 MCL-Maximum contaminant level,
				MRDL-Maximum residual disinfectant level, TT-Treatment technique
3 The term Violations of State
				Primary Drinking Water Regulations (SPDWR) is used here to include violations
				of MCL, MRDL, treatment technique, monitoring, and testing procedure
				requirements.
4 Failure to test for fecal coliform
				or E. coli is a Tier 1 violation if testing is not done after any repeat sample
				tests positive for coliform. All other total coliform monitoring and testing
				procedure violations are Tier 3.
5 Systems that violate the turbidity
				MCL of 5 NTU based on an average of measurements over two consecutive days must
				consult with the Department within 24 hours after learning of the violation.
				Based on this consultation, the Department may subsequently decide to elevate
				the violation to Tier 1. If a system is unable to make contact with the
				Department in the 24-hour period, the violation is automatically elevated to
				Tier 1.
6 Systems with treatment technique
				violations involving a single exceedance of a maximum turbidity limit under the
				Surface Water Treatment Rule (SWTR) Interim Enhanced Surface Water Treatment
				Rule (IESWTR), or the Long Term 1 Enhanced Surface Water Treatment Rule
				(LT1ESWTR) are required to consult with the Department within 24 hours after
				learning of the violation. Based on this consultation, the Department may
				subsequently decide to elevate the violation to Tier 1. If a system is unable
				to make contact with the Department in the 24-hour period, the violation is
				automatically elevated to Tier 1.
7 Most of the requirements of the
				Interim Enhanced Surface Water Treatment Rule, R.61-58.10.B - C become effective
				January 1, 2002 for surface water systems and ground water systems under the
				direct influence of surface water serving at least 10,000 persons. However,
				R.61-58.10.H(3) has
				some requirements that become effective as early as April 16, 1999. The Surface
				Water Treatment Rule remains in effect for systems serving at least 10,000
				persons even after 2002; the Interim Enhanced Surface Water Treatment Rule adds
				additional requirements and does not in many cases supersede the SWTR.
8 The arsenic MCL citations are
				effective January 23, 2006. Until then the citations are R.61-58.5(B)(2).
9 The arsenic Tier 3 violations MCL
				citations are effective January 23, 2006. Until then, the citations are
				R.61-58.C(7).
10 Failure to take a confirmation
				sample within 24 hours for nitrate or nitrite after an initial sample exceeds
				the MCL is a Tier 1 violation. Other monitoring violations for nitrate are Tier
				3.
11 The uranium MCL, Tier 2 violation
				citations are effective December 8, 2003 for all community water
				systems.
12 The uranium Tier 3 violation
				citations are effective December 8, 2000 for all community water
				systems.
13 Community and non-transient
				non-community surface water systems and ground water systems under the direct
				influence of surface water serving 10,000 must comply with new DBP MCLs,
				disinfectant MRDLs, and related monitoring requirements beginning January 1,
				2002. All other community and non-transient non-community systems must meet the
				MCLs and MRDLs beginning January 1, 2004. Transient non-community surface water
				systems and ground water systems under the direct influence of surface water
				serving 10,000 or more persons and using chlorine dioxide as a disinfectant or
				oxidant must comply with the chlorine dioxide MRDL beginning January 1, 2002.
				Transient non-community surface water systems and ground water systems under
				the direct influence of surface water serving fewer than 10,000 persons and
				using only ground water not under the direct influence of surface water and
				using chlorine dioxide as a disinfectant or oxidant must comply with the
				chlorine dioxide MRDL beginning January 1, 2004.
14 R.61-58.5.L, and R.61-58.13.C(1) -
				(2) apply until R.61-58.14 and R.61-58.15 take effect under the
				schedule in R.61-58.14.
15 Failure to monitor for chlorine
				dioxide at the entrance to the distribution system the day after exceeding the
				MRDL at the entrance to the distribution system is a Tier 2 violation.
16 If any daily sample taken at the
				entrance to the distribution system exceeds the MRDL for chlorine dioxide and
				one or more samples taken in the distribution system the next day exceed the
				MRDL, Tier 1 notification is required. Failure to take the required samples in
				the distribution system after the MRDL is exceeded at the entry point also
				triggers Tier 1 notification.
17 Some water systems must monitor
				for certain unregulated contaminants listed in R.61-58.5.T
18 This citation refers to the
				requirements of R.61-58.9 that "a schedule
				prescribed ...for a public water system granted a variance [or exemption] shall
				require compliance by the system ..."
19 In addition to R.61-58.9 specifies the items and
				schedule milestones that must be included in a variance for small systems.
				20 Other waterborne emergencies require a Tier 1
				public notice under R.61-58.6.E(2)(a)
				for situations that do not meet the definition of a waterborne disease outbreak
				given in R.61-58.B(174) but
				that still have the potential to have serious adverse effects on health as a
				result of short-term exposure. These could include outbreaks not related to
				treatment deficiencies, as well as situations that have the potential to cause
				outbreaks, such as failures or significant interruption in water treatment
				processes, natural disasters that disrupt the water supply or distribution
				system, chemical spills, or unexpected loading of possible pathogens into the
				source water.
21 The Department may place other
				situations in any tier they believe appropriate, based on threat to public
				health.
22 Failure to collect three or more
				samples for Cryptosporidium analysis is a Tier 2 violation requiring special
				notice as specified in R.61-58.6.E(11).
				All other monitoring and testing procedure violations are Tier 3.
