Ohio Admin. Code 3745-81-80 - Control of lead and copper - general requirements
(A) Applicability. The requirements of rules
3745-81-80 to
3745-81-90 of the Administrative
Code are based on the national primary drinking water regulations for lead and
copper. Unless otherwise indicated, each of the provisions of these rules
applies to community water systems and nontransient noncommunity water systems
(hereinafter referred to as "water systems" or "systems").
(B) Scope. These regulations establish a
treatment technique that includes requirements for corrosion control treatment,
source water treatment, lead service line replacement, and public education.
Lead and copper action levels, measured in samples collected at consumers'
taps, may trigger these requirements.
(C) Lead and copper action level s, and lead threshold level s.
(1) The lead action level is exceeded if, at any time during the monitoring period, the
concentration of lead in more than ten per cent of tap water samples collected
during any monitoring period conducted in accordance with rule
3745-81-86 of the Administrative
Code is greater than 0.015 milligram per liter, i.e., if the ninetieth
percentile lead level is greater than 0.015 milligram per liter.
(2) The copper action level is exceeded
if, at any time during the monitoring period, the
concentration of copper in more than ten percent of tap water samples collected
during any monitoring period conducted in accordance with rule
3745-81-86 of the Administrative
Code is greater than 1.3 milligrams per liter, i.e., if the ninetieth
percentile copper level is greater than 1.3 milligrams per liter.
(3) The ninetieth percentile lead and copper
levels shall be computed as follows:
(a) The
analytical results of all lead or copper samples taken during a monitoring
period shall be placed in ascending order from the sample with the lowest
concentration to the sample with the highest concentration. Each analytical
result shall be assigned a consecutive whole number, beginning with the number
one for the sample with the lowest contaminant level. The number assigned to
the sample with the highest contaminant level shall be that of the total number
of samples analyzed.
(i)
If less than the minimum number of samples required by
rule 3745-81-86 of the Administrative
Code have been taken, the minimum number of samples shall be used in
calculations.
(ii)
If greater than or equal to the minimum number of
samples required by rule
3745-81-86 of the Administrative
Code have been taken, the total number of samples shall be used in
calculations.
(b)
The number of samples taken during the monitoring period shall be multiplied by
0.9.
(c) The contaminant
concentration in the numbered sample with the number yielded by the calculation
in paragraph (C)(3)(b) of this rule is the ninetieth percentile contaminant
level.
If the result of the calculation in
paragraph (C)(3)(b) of this rule is not a whole number, the concentrations for
the samples above and below the result shall be iterated to yield the ninetieth
percentile
(d) For public water systems that monitor
five samples per monitoring period, the ninetieth percentile is computed by
taking the average for the two samples with highest concentrations.
(e) For public water systems that have been
allowed by the director to collect fewer than five samples under rule
3745-81-86 of the Administrative
Code, the sample result with the highest concentration is considered the
ninetieth percentile value.
(4)
The lead
threshold level is exceeded at 0.015 milligrams per liter concentration of lead
in an individual tap water sample.
(D) Corrosion control treatment requirements.
(1) All water systems shall install and
operate optimal corrosion control treatment as defined in rule
3745-81-01 of the Administrative
Code.
(2) Any water system that
complies with the applicable corrosion control treatment requirements approved
by the director under rules
3745-81-81 and
3745-81-82 of the Administrative
Code shall be deemed in compliance with the treatment requirement contained in
paragraph (D)(1) of this rule.
(E) Source water treatment requirements. Any
system exceeding the lead or copper action level shall implement all applicable
source water treatment requirements specified by the director under rule
3745-81-83 of the Administrative
Code.
(F) Lead service line
replacement requirements. Any system
exceeding
that
replaces lead service lines, replaces water mains in areas that contain or are
likely to contain lead service lines or exceeds the lead action level
after implementation of applicable corrosion control and source water treatment
requirements shall complete the
lead service line
replacement requirements contained in rule
3745-81-84 of the Administrative
Code.
(G) Consumer notification, lead public notification
and public education
requirements.(2)
(3) Public education. Any system exceeding the lead
action level shall implement the public education requirements contained in
rule 3745-81-85 of the Administrative
Code.
(1) Consumer notification.
Pursuant to paragraph (D) of rule
3745-81-85 of the Administrative
Code, all
the owner
or operator of a public water systems
system shall
provide a consumer notice of lead tap water monitoring results to persons
served at the sites (taps) that are sampled.
(2)
Lead public
notification . Any system with results of lead tap water monitoring that show an
exceedance of the lead action level shall provide lead public notification in
accordance with rule
3745-81-85 of the Administrative
Code.
(H) Monitoring and
analytical requirements. Monitoring of tap water for lead and copper,
monitoring for water quality parameters, monitoring of source water at each
entry point to the distribution system for lead and copper, and analyses of
these monitoring samples shall be completed in compliance with rules
3745-81-86 to
3745-81-89 of the Administrative
Code and Chapter 3745-89(laboratory approval) of the Administrative
Code.
(I) Reporting requirements.
Public water systems shall report to the director any information required by
the treatment provisions of rules
3745-81-80 to
3745-81-90 of the Administrative
Code.
(J) Recordkeeping
requirements. Public water systems shall maintain records in accordance with
rule 3745-81-90 of the Administrative
Code.
(K) Violation of primary
drinking water regulations. Failure to comply with the applicable requirements
of rules
3745-81-80 to
3745-81-90 of the Administrative
Code, including requirements established by the director pursuant to these
provisions, shall constitute a violation of the Administrative Code primary
drinking water regulations for lead and/or
or
copper.
