Ohio Administrative Code › Title 3745 - Ohio Environmental Protection Agency › Chapter 3745-81 - Primary Drinking Water Rules › Section 3745-81-84 - Control of lead and copper - lead service line requirements

Current through all regulations passed and filed through July 1, 2024
All water systems that replace lead
				service lines, replace water mains in areas that contain or are likely to
				contain lead service lines, or exceed the lead action level after the
				implementation of corrosion control or source water treatment shall comply with
				all applicable requirements in this rule.
(A)
								
								Requirements for
			 public water systems that exceed the lead action level in tap water
			 monitoring pursuant to paragraph (D)(2) of rule
			 3745-81-86
			 of the Administrative Code, after installing corrosion control
			 or
			 source water treatment (whichever sampling occurs later).
(1)
									The water system
			 shall identify the initial number of lead service lines in its distribution
			 system, including an identification of the portion owned by the system, based
			 on a materials evaluation, including the evaluation required under paragraph
			 (A) of rule
			 3745-81-86
			 of the Administrative Code and relevant legal authorities regarding the portion
			 owned by the system (e.g., contracts and local ordinances).
(2)
									The water system
			 shall replace annually at least seven per cent 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 first year of lead service line replacement shall begin on the
			 first day following the end of the monitoring period in which the action level
			 was exceeded under paragraph (A) of this rule. If monitoring is required
			 annually, or triennially, the end of the monitoring period is September
			 thirtieth of the calendar year in which the sampling occurs. If the director
			 has established an alternate period, then the end of the monitoring period will
			 be the last day of that period.
The director shall require a public
				water system to replace lead service lines on a shorter schedule than that
				required by this rule, taking into account the number of lead service lines in
				the system, where such a shorter replacement schedule is feasible. The director
				shall make this determination in writing and notify the system of the finding
				within six months after the system is required to commence lead service line
				replacement based on monitoring referenced in this paragraph.
(3)
									If the
			 water system is in violation of rule
			 3745-81-81
			 or rule
			 3745-81-83
			 of the Administrative Code for failure to install source water treatment or
			 corrosion control treatment, the director may require the system to commence
			 lead service line replacement under this rule after the date by which the
			 system was required to conduct monitoring under paragraph (D)(2) of rule
			 3745-81-86
			 of the Administrative Code has passed.
(4)
									Any public water
			 system may cease replacing lead service lines whenever first- draw samples
			 collected pursuant to paragraph (B)(2) of rule
			 3745-81-86
			 of the Administrative Code meet the lead action level during each of two
			 consecutive monitoring periods and the system submits the results to the
			 director. If first-draw tap samples monitored in any such water system
			 thereafter exceed the lead action level, the system shall recommence replacing
			 lead service lines, pursuant to paragraph (C) of this rule.
(5)
									Any water system
			 resuming a lead service replacement program after the cessation of its lead
			 service line replacement program, as allowed by paragraph (A)(4) of this rule,
			 shall update its inventory of lead service lines. 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 (seven per cent lead service line replacement is based on a fifteen year
			 replacement program: e.g., systems resuming lead service line replacement after
			 previously conducting two years of replacement would divide the updated
			 inventory by thirteen). For those systems that have completed a fifteen 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
(6)
									The water system
			 shall replace lead service lines in accordance with the requirements of
			 paragraph (C) of this rule.
(7)
									The water system
			 shall report to the director the information specified in paragraph (E) of rule
			 3745-81-90
			 of the Administrative Code.
