Nebraska Administrative Code › Topic - HEALTH AND HUMAN SERVICES SYSTEM › Title 179 - PUBLIC WATER SYSTEMS › Chapter 12 - CONTROL OF LEAD AND COPPER › Section 179-12-007 - LEAD SERVICE LINE REPLACEMENT REQUIREMENTS

Current through June 17, 2024
007.01 Systems that
				fail to meet the lead action level in tap samples taken pursuant to 179 NAC
				12-009.04B, after
				installing corrosion control and/or source water treatment (whichever sampling
				occurs later), must replace lead service lines in accordance with the
				requirements of 179 NAC 12-007. If a system is in violation of 179 NAC
				12-004 or
				12-006 for failure to install source
				water or corrosion control treatment, the Director may require the system to
				commence lead service line replacement under 179 NAC 12-007 after the date by
				which the system was required to conduct monitoring under 179 NAC
				12-009.04B has
				passed.
007.02 Replacement Schedule
12-007.02A A water system must replace
				annually at least 7% of the initial number of lead service lines in its
				distribution system. The initial number of lead service lines is the number of
				lead lines in place at the time the replacement program begins. The system must
				identify the initial number of lead service lines in its distribution system,
				including an identification of the portion(s) owned by the system, based on a
				materials evaluation, including the evaluation required under 179 NAC 12 -
				009.01 and relevant legal authorities ( e.g., contracts, local ordinances)
				regarding the portion owned by the system. The first year of lead service line
				replacement begins on the first day following the end of the monitoring period
				in which the action level was exceeded under 17 9 NAC 12 - 007.01. If
				monitoring is required annually or less frequently, the end of the monitoring
				period is September 30 of the calendar year in which the sampling occurs. If
				the Director has established an alternate monitoring period, then the end of
				the monitoring period will be the last day of that period.
12-007.02B Any water system resuming a lead
				service line replacement program after the cessation of its lead service line
				replacement program as allowed by 179 NAC 12-007.06 must update its inventory
				of lead service lines to include those sites that were previously determined
				not to require replacement through the sampling provision under 179 NAC
				12-007.03. The system will then divide the updated number of remaining lead
				service lines by the number of remaining years in the program to determine the
				number of lines that must be replaced per year (7% lead service line
				replacement is based on a 15 - year replacement program, so, for example,
				systems resuming lead service line replacement after previously conducting two
				years of replacement would divide the updated inventory by 13). For those
				systems that have completed a 15 - year lead service line replacement program,
				the Director will determine a schedule for replacing or retesting lines that
				were previously tested out under the replacement program when the system
				re-exceeds the action level.
