Current through June 17, 2024
Comprehensive performance evaluation
				  (CPE)
is a thorough review and analysis of a treatment plant's
				  performance-based capabilities and associated administrative, operation and
				  maintenance practices. It is conducted to identify factors that may be
				  adversely impacting a plant's capability to achieve compliance and emphasizes
				  approaches that can be implemented without significant capital improvements.
				  For the purpose of compliance with 179 NAC 17 and 179 NAC 19, the comprehensive
				  performance evaluation must consist of at least the following components:
				  Assessment of plant performance; evaluation of major unit processes;
				  identification and prioritization of performance limiting factors; assessment
				  of the applicability of comprehensive technical assistance; and preparation of
				  a CPE report.
Disinfection profile
is a summary
				  of
Giardia iambiia
inactivation through the treatment plant.
				  The procedure for developing a disinfection profile is contained in 179 NAC
				  17-004 (Disinfection profiling and
				  benchmarking) in 179 NAC 17 and 179 NAC 19-007.01 to 19-007.07 (Disinfection
				  profile) in 179 NAC 19.
Ground water under the direct influence of
				  surface water (GWUDI)
means any water beneath the surface of the
				  ground with significant occurrence of insects or other macroorganisms, algae,
				  or large-diameter pathogens such as
Giardia iambiia
or
Cryptosporidium,
or significant and relatively rapid shifts in
				  water characteristics such as turbidity, temperature, conductivity, or pH which
				  closely correlate to climatological or surface water conditions. Direct
				  influence must be determined for individual sources in accordance with the
				  criteria established by the Director.
The Director determination of direct influence may be based
				  on site-specific measurements of water quality and/or documentation of well
				  construction characteristics and geology with field
				  evaluation.

Current through June 17, 2024
007.01 What It Is,
				Who Must Develop One
A disinfection profile is a graphical representation of a
				  system's level of
Giardia iambiia
or virus inactivation
				  measured during the course of a year. Community and non-transient non-community
				  water systems that use surface water or ground water under the direct influence
				  of surface water and serve fewer than 10,000 persons must develop a
				  disinfection profile unless the Director determines the system's profile is
				  unnecessary. The Director may approve the use of a more representative data set
				  for disinfection profiling than the data set required under 179 NAC 19-007.03
				  to 19-007.07.
007.02
				Criteria used by the Director to determine that a profile is unnecessary
The Director may only determine that a system's profile is
				  unnecessary if a system's TTHM and HAA5 levels are below 0.064 mg/L and 0.048
				  mg/L, respectively. To determine these levels, TTHM and HAA5 samples must be
				  collected after January 1, 1998, during the month with the warmest water
				  temperature, and at the point of maximum residence time in the distribution
				  system. The Department may approve a more representative TTHM and HAA5 data set
				  to determine these levels.
007.03 Development of a disinfection profile,
				when to begin
A disinfection profile consists of three steps:
1. First, collect data for several parameters
				from the plant as discussed in 179 NAC 19-007.04 over the course of 12 months.
				Systems serving between 500 and 9,999 persons must begin collecting the data no
				later than July 1, 2003. Systems serving fewer than 500 persons must begin to
				collect data no later than January 1, 2004.
2. Second, use this data to calculate weekly
				log inactivation as discussed in 179 NAC 19-007.05 and 19-007.06; and
3. Third, use these weekly log inactivations
				to develop a disinfection profile as specified in 179 NAC 19-007.07.

Current through June 17, 2024
008.01 Who Must
				Develop a Disinfection Benchmark
Systems that use surface water or ground water under the
				  direct influence of surface water that are required to develop a disinfection
				  profile under 179 NAC 19-007.01 through 19-007.07 must develop a disinfection
				  benchmark if they decide to make a significant change to their disinfection
				  practice. These systems must consult with the Director for approval before
				  implementing a significant disinfection practice change.
008.02 Significant changes to disinfection
				practices include:
1. Changes to the point of
				disinfection;
2. Changes to the
				disinfectant(s) used in the treatment plant; or
3. Changes to the disinfection
				process.

009.01 All systems
				that use surface water or ground water under the direct influence of surface
				water and serve fewer than 10,000 persons, are required to filter, and utilize
				filtration other than slow sand filtration or diatomaceous earth filtration
				must meet the combined filter effluent turbidity requirements of 179 NAC
				19-009.02 to 19-009.04. Systems that use slow sand or diatomaceous earth
				filtration are not required to meet the combined filter effluent turbidity
				limits of 179 NAC 19, but they must continue to meet the combined filter
				effluent turbidity limits in 179 NAC
				13-006.
009.02 Strengthened Combined Filter Effluent
				Turbidity Limits
Systems must meet two strengthened combined filter effluent
				  turbidity limits:
1. The first
				combined filter effluent turbidity limit is a "95th
				percentile" turbidity limit that systems must meet in at least 95% of the
				turbidity measurements taken each month. Measurements must continue to be taken
				as described in 179 NAC 13-007.01 and 13-007.03. Monthly reporting must be
				completed according to 179 NAC 19-011.01. The following table describes the
				required limits for specific filtration technologies.

0.3 NTU.
2. All other "Alternative" Filtration
A value determined by the Director (not to exceed 1
								NTU) based on the demonstration described in 179 NAC 19-009.03.
2.
				The second combined filter effluent turbidity limit is a "maximum" turbidity
				limit which your system may at no time exceed during the month. Measurements
				must continue to be taken as described in 179 NAC 13-007.01 and 13-007.03.
				Monthly reporting must be completed according to 179 NAC 19-011.01. The
				following table describes the required limits for specific filtration
