Current through June 17, 2024
Clean Compliance History
means, for
				  the purposes of 179 NAC 26, a record of no maximum contaminant level (MCL)
				  violations under 179 NAC
				  2-002.04C; no
				  monitoring violations under 179 NAC
				  3-004 or 179 NAC 26; and no coliform
				  treatment technique trigger exceedances or treatment technique violations under
				  179 NAC 26.
Code of Federal Regulations (CFR)
means the Code of Federal Regulations as it existed on the effective date of
				  these regulations, and any CFR citations mentioned in these regulations are
				  hereby incorporated by reference. Copies of the CFR as it existed on the
				  effective date of these regulations can be obtained on the DHHS website at
http://dhhs.ne.gov/publichealth/Pages/enh_pwsindex.aspx
or by requesting via email a copy from the Department at:
DHHS.drinkgwater@nebraska.gov
or by calling
				  402-471-2541.
Department
means the Division of
				  Public Health of the Department of Health and Human Services.
Level 1 Assessment
means an
				  evaluation to identify the possible presence of sanitary defects, defects in
				  distribution system coliform monitoring practices, and (when possible) the
				  likely reason that the system triggered the assessment. It is conducted by the
				  system operator or owner. Minimum elements 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 (e.g., whether a ground water
				  system is disinfected); existing water quality monitoring data; and
				  inadequacies in sample sites, sampling protocol, and sample processing. The
				  system must conduct the assessment consistent with any Department directives
				  that tailor specific assessment elements with respect to the size and type of
				  the system and the size, type, and characteristics of the distribution
				  system.
Level 2 Assessment
means an
				  evaluation to identify the possible presence of sanitary defects, defects in
				  distribution system coliform monitoring practices, and (when possible) the
				  likely reason that the system triggered the assessment. A Level 2 assessment
				  provides a more detailed examination of the system (including the system's
				  monitoring and operational practices) than does a Level 1 assessment through
				  the use of more comprehensive investigation and review of available
				  information, additional internal and external resources, and other relevant
				  practices. It is conducted by an individual approved by the Department, which
				  may include the system operator. Minimum elements 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 (e.g., whether a
				  ground water system is disinfected); existing water quality monitoring data;
				  and inadequacies in sample sites, sampling protocol, and sample processing. The
				  system must conduct the assessment consistent with any Department directives
				  that tailor specific assessment elements with respect to the size and type of
				  the system and the size, type and characteristics of the distribution system.
				  The system must comply with any expedited actions or additional actions
				  required by the Department in the case of an
E. coli
MCL
				  violation.
Sanitary Defect
means a defect that
				  could provide a pathway of entry for microbial contamination into the
				  distribution system or that is indicative of a failure or imminent failure in a
				  barrier that is already in place.
Seasonal System
means a
				  non-community water system that is not operated as a public water system on a
				  year-round basis and starts up and shuts down at the beginning and end of each
				  operating season.
