(5) Notifying all customers served by the
			 water system, as prescribed by OAR
			 333-061-0042, when
			 reporting requirements are not being met, when public health hazards are found
			 to exist in the system, or when the operation of the system is subject to a
			 permit or a variance;

Oregon Administrative Rules › Chapter 333 - OREGON HEALTH AUTHORITY, PUBLIC HEALTH DIVISION › Division 61 - DRINKING WATER › Section 333-061-0030 - Maximum Contaminant Levels and Action Levels

Current through Register Vol. 63, No. 7, July 1, 2024
(1) MCLs and action levels (ALs) for
			 inorganic chemicals apply to all community and NTNC water systems and are
			 listed in Table 1, except the MCL for fluoride which applies only to community
			 water systems and the MCL for nitrate which applies to all water systems.
(a) Compliance with the MCLs for inorganic
			 contaminants is calculated pursuant to OAR 333-061-0036(2)(h).
(b) Exceeding the secondary contaminant level
			 for fluoride as specified in section (6) of this rule requires a special public
			 notice as specified in OAR 333-061-0042(7).
(c) The lead action level is exceeded if the
			 concentration of lead in more than 10 percent of tap water samples collected
			 during any monitoring period conducted in accordance with OAR
			 333-061-0036(10)(a) through (e)  is greater than 0.015 mg/L (that is, if the
			 "90th percentile" lead level is greater than 0.015 mg/L). The copper action
			 level is exceeded if the concentration of copper in more than 10 percent of tap
			 water samples collected during any monitoring period conducted in accordance
			 with OAR 333-061-0036(10)(a) through (e)  is greater than 1.3 mg/L (that is, if
			 the "90th percentile" copper level is greater than 1.3 mg/L).
(A) The 90th percentile lead and copper
			 levels shall be computed as follows: The results of all lead or copper samples
			 taken during a monitoring period shall be placed in ascending order from the
			 sample with the lowest concentration to the sample with the highest
			 concentration. Each sampling result shall be assigned a number, ascending by
			 single integers beginning with the number 1 for the sample with the lowest
			 contaminant level. The number assigned to the sample with the highest
			 contaminant level shall be equal to the total number of samples taken. The
			 number of samples taken during the monitoring period shall be multiplied by
			 0.9. The contaminant concentration in the numbered sample yielded by this
			 calculation is the 90th percentile contaminant level.
(B) For water systems serving fewer than 100
			 people that collect five samples per monitoring period, the 90th percentile is
			 computed by taking the average of the highest and second highest
			 concentrations. For a water system allowed by the Authority to collect fewer
			 than five samples the sample result with the highest concentration is
			 considered the 90th percentile value.

			 conducted by the water supplier or a representative thereof. Minimum elements
			 of the investigation include review and identification of atypical events that
			 could affect distributed water quality or indicate that distributed water
			 quality was impaired; changes in distribution system maintenance and operation
			 that could affect distributed water quality (including water storage); source
			 and treatment considerations that bear on distributed water quality, where
			 appropriate (for example, whether a ground water system is disinfected);
			 existing water quality monitoring data; and inadequacies in sample sites,
			 sampling protocol, and sample processing.
(b) A level 2 coliform investigation is
			 conducted by the Authority or a party approved by the Authority and is a more
			 detailed and comprehensive examination of a water system (including the
			 system's monitoring and operational practices) than a level 1 investigation.
			 Minimum elements include those that are part of a level 1 investigation and
			 additional review of available information, internal and external resources,
			 and other relevant practices. Water suppliers must comply with any expedited
			 actions or additional actions required by the Authority in the case of an

			 authorized to approve the formation, dissolution, consolidation and expansion
			 of water systems not owned by cities. In doing so, counties or boundary
			 commissions should consider whether water service is extended in a logical
			 fashion and whether water systems have a financial base sufficient for
			 operation and maintenance.
(4) The
			 Authority may delegate upon request any of its duties as set forth in these
			 rules to counties. In doing so, theAuthority shall require assurances that the
			 county shall:

Current through Register Vol. 63, No. 7, July 1, 2024
Water suppliers must pay an annual fee to partially defray the
				cost of the Authority's regulation of public water systems.
(1) The fee is based on the classification of
			 the water system according to Table 44.
(a)
			 For campgrounds where multiple handpumps exist, a single fee will be
			 assessed.

			 systems, the fee is based upon the number of service connections or the
			 population served by the water system and water treatment applied at the water
			 system.
(A) Only water treatment applied to
			 comply with a water quality standard or treatment technique is considered when
			 determining this fee. The Authority does not consider supplemental
			 fluoridation, disinfectant residual maintenance, or treatment for secondary
			 contaminants to be treatment for purposes of determining this fee.

			 250 service connections or less but serving more than 1,000 people, the lesser
			 of the two fees will be assessed.
(C) For water systems with more than 250
			 service connections, the fee is based on the number of connections.
(D) For water systems without a distribution
			 system and where water is exclusively delivered on a wholesale basis, the fee
			 is based on the total population served by the water systems purchasing water
			 directly from the wholesaler.
