Ohio Administrative Code › Title 3745 - Ohio Environmental Protection Agency › Chapter 3745-81 - Primary Drinking Water Rules › Section 3745-81-86 - Control of lead and copper - monitoring requirements for lead and copper in tap water

Current through all regulations passed and filed through July 1, 2024
(A) Sample site location
			 and mapping requirements.
(1)
									
									Each public water system
			 shall complete a materials evaluation of the distribution
			 system in order to identify a pool of targeted sampling sites that meets the
			 requirements of this rule and is sufficiently large to ensure that the public
			 water system can collect the number of lead and copper tap samples required in
			 paragraph (C) of this rule. All sites from which first-draw samples are
			 collected shall be selected from this pool of targeted sampling sites. Sampling
			 sites may not include taps that have point-of-use or point-of-entry
			 treatment devices designed to remove inorganic contaminants.
(2) A public water system shall use any
			 information on lead, copper, and galvanized steel that
			 the system
			 has collected in corrosivity monitoring when conducting a materials evaluation.
			 When such information is insufficient to locate the requisite number of lead
			 and copper sampling sites that meet the targeting criteria in paragraph (A) of
			 this rule, the public water system shall review the following sources of information
			  in order to identify a
			 sufficient number of sampling sites:
(a) All plumbing
			 codes, permits, and records in the files of the building
			 department which indicate the plumbing materials that
			 are installed within publicly and privately owned structures connected to the
			 distribution system.
(b)
			 Inspections and records of the distribution system that indicate the material
			 composition of the service connections that connect a structure to the
			 distribution system.
(c) All
			 existing water quality information, which includes the results of all prior
			 analyses of the system or individual structures connected to the system,
			 indicating locations that may be particularly susceptible to high lead or
			 copper concentrations.
In addition, the system shall seek to
				collect such information where possible in the course of normal operations
				(e.g., checking service line materials while reading water meters or performing
				maintenance activities).
(3) The sampling sites selected for a
			 community public water system's sampling pool ("tier one sampling sites") shall
			 consist of single family structures that meet one of
			 the following:
(a) Contain copper pipes
			 with lead solder installed after 1982 and before
			 1989 or contain lead pipes; or.
(b) Are served by a lead service line. When
			 multiple-family residences comprise at least twenty per cent of the structures
			 served by a public water system, the system may include these types of
			 structures in the sampling pool.
(4) Any community public water system with
			 insufficient tier one sampling sites shall complete the sampling pool
			 with "tier two sampling sites", consisting of buildings, including
			 multiple-family residences, that meet one of the
			 following:
(a) Contain copper pipes with
			 lead solder installed after 1982 and before 1989
			 or contain lead pipes; or.
(b) Are served by a lead service
			 line.
(5) Any community
			 public water system with insufficient tier one and tier two sampling sites
			 shall complete the sampling pool with "tier three sampling sites",
			 consisting of single family structures that contain copper pipes with lead
			 solder installed before 1983. A community public water system with insufficient
			 tier 1, tier 2, and tier 3 sampling sites shall complete
			 the
			 sampling pool with representative sites throughout the distribution system. For
			 the purpose of this paragraph, a representative site is a site in which the
			 plumbing materials used at that site would be commonly found at other sites
			 served by the public water system.
(6) The sampling sites selected for a
			 nontransient noncommunity public water system ("tier one sampling sites") shall
			 consist of buildings that meet one of the
			 following:
(a) Contain copper pipes
			 with lead solder installed after 1982 and before
			 1989 or contain lead pipes.
(b) Are
			 served by a lead service line.
(7) A nontransient noncommunity public water
			 system with insufficient tier one sites that meet the targeting criteria in
			 paragraph (A)(6) of this rule shall complete the sampling pool
			 with sampling sites that contain copper pipes with lead solder installed before
			 1983. If additional sites are needed to complete the sampling pool, the
			 nontransient noncommunity water system shall use representative sites
			 throughout the distribution system. For the purpose of this paragraph, a
			 representative site is a site in which the plumbing materials used at that site
			 would be commonly found at other sites served by the public water
			 system.
(8) Any public water system
			 whose distribution system contains lead service lines shall draw fifty per cent
			 of the samples collected during each monitoring period from sites
			 that contain lead pipes, or copper pipes with lead solder, and fifty per cent
			 of those samples from sites served by a lead service line. A public water
			 system that cannot identify a sufficient number of sampling sites served by a
			 lead service line shall collect first-draw samples from all of the sites
			 identified as being served by such lines.
(9)
									Mapping
			 requirements.
The owner or operator of a community or
				nontransient noncommunity water system shall do all of the following, as
				applicable:
(a)
										Community water systems.
The owner or operator shall identify
				and map areas of the system that are known or likely to contain lead service
				lines, and identify characteristics of buildings served by the system that may
				have solder, fixtures or pipes that contain lead. Characteristics of buildings
				may be described in a narrative referenced in paragraph (A)(9)(d) of this
				rule.
(b)
										Single building community water systems and
			 nontransient noncommunity water systems.
The owner or operator shall identify
				and map areas of the system with solder, fixtures or pipes containing lead in
				buildings served by the system. Characteristics of the system may be described
				in a narrative referenced in paragraph (A)(9)(d) of this rule.
(c)
										Submit
			 a copy of the applicable map to the Ohio department of health and the Ohio
			 department of job and family services.
(d)
										The applicable
			 map, and a list of sampling site locations identified in paragraphs (A)(1) to
			 (A)(8) of this rule including the contact information for the owner and
			 occupant for each sampling site shall be submitted to the director. Water
			 systems may submit a narrative providing additional detail (e.g., description
			 of the building and the plumbing materials) with the map and list of sampling
			 site locations. The documentation submitted shall be acceptable and
			 complete.
(e)
										The owner or operator of an existing community or
			 nontransient noncommunity water system shall complete the initial submission of
			 the information specified in paragraphs (A)(9)(a) or (A)(9)(b) of this rule in
			 accordance with section
			 6109.121 of the Revised Code.
			 The owner or operator of a new community or nontransient noncommunity water
			 system shall complete the initial submission of the information specified in
			 paragraph (A)(9)(a) or (A)(9)(b) of this rule when applying for plan approval
			 in accordance with Chapter 3745-91 of the Administrative Code.
(f)
										The water system
			 owner or operator shall update and resubmit information required in paragraphs
			 (A)(9)(a) to (A)(9)(d) of this rule once every five years, beginning five years
			 after March 9, 2017.
