Ohio Admin. Code 3745-81-83 - Control of lead and copper; source water treatment requirements
Public water systems shall complete the applicable
(A) Deadlines for completing source water
treatment steps.
(1) Step one: a system
exceeding the lead or copper action level shall complete source water at the
entry point to the distribution system monitoring for lead and copper (in
accordance with paragraph (B) of rule
3745-81-88 of the Administrative
Code), make a treatment recommendation, and submit approvable plans, if needed,
to the director (in accordance with paragraph (B)(1) of this rule) no later
than one hundred eighty days after the end of the monitoring period during
which the lead or copper action level was exceeded.
If monitoring is required annually, triennially, or less
frequently, the end of the monitoring period is September thirtieth of the
calendar year in which the sampling occurs. If the
(2) Step two:
the director shall complete the review and approval of plans regarding source
water treatment (in accordance with paragraph (B)(2) of this rule) within six
months after submission of monitoring results under step one.
(3) Step three: if the director requires
installation of source water treatment, the system shall install the treatment
(in accordance with paragraph (B)(3) of this rule) within twenty-four months
after completion of step two.
(4)
Step four: the system shall complete follow-up tap water monitoring (in
accordance with paragraph (D)(2) of rule
3745-81-86 of the Administrative
Code) and source water at the entry point to the distribution system monitoring
(in accordance with paragraph (C) of rule
3745-81-88 of the Administrative
Code) within thirty-six months after completion of step two.
(5) Step five: the director shall review the
system's installation and operation of source water treatment and specify
maximum permissible source water at the entry point to the distribution system
levels (in accordance with paragraph (B)(4) of this rule) within six months
after completion of step four.
(6)
Step six: the system shall operate in compliance with the director -specified
maximum permissible lead and copper source water at the entry point to the
distribution system levels (in accordance with paragraph (B)(4) of this rule)
and continue monitoring (in accordance with paragraph (D) of rule
3745-81-88 of the Administrative
Code).
(B) Description
of source water treatment requirements.
(1)
System treatment recommendation. Any system which exceeds the lead or copper
action level shall recommend in writing to the director the installation and
operation of one of the source water treatments listed in paragraph (B)(2) of
this rule. A system may recommend that no treatment be installed based upon a
demonstration that source water treatment is not necessary to minimize lead and
copper levels at user's taps.
(2)
Director determination regarding source water treatment. The director shall
complete an evaluation of the results of all source water at the entry point to
the distribution system monitoring submitted by the water system to determine
whether source water treatment is necessary to minimize lead or copper levels
in water delivered to users' taps. If the director determines that treatment is
needed, the system shall submit approvable plans for source water treatment
selected from ion exchange, reverse osmosis, lime softening, or
coagulation /filtration . If the director requests additional information to aid
in the review, the water system shall provide the information by the date
specified in the director 's request. The director shall notify the system in
writing of the determination and set forth the basis for the decision.
(3) Installation of source water
treatment. Each system shall properly install and operate the source water
treatment approved by the director under paragraph (B)(2) of this rule.
(4) Director 's review of source
water treatment and specification of maximum permissible levels of lead and
copper at source water at the entry points to the distribution system. The
director shall review the source water at the entry point to the distribution
system monitoring completed by the water system both before and after the
system installs source water treatment, and determine whether the system has
properly installed and operated the source water treatment approved by the
director . Based upon the review, the director shall specify the maximum
permissible lead and copper concentrations for finished water entering the
distribution system. Such levels shall reflect the contaminant removal
capability of the treatment properly operated and maintained. The director
shall notify the system in writing and explain the basis for the decision.
(5) Continued operation and
maintenance. Each water system shall maintain lead and copper levels below the
maximum permissible concentrations specified by the director at each sampling
point monitored in accordance with rule
3745-81-88 of the Administrative
Code. The system is out of compliance with this paragraph if the level of lead
or copper at any sampling point is greater than the maximum permissible
concentration specified by the director .
(6) Modification of director treatment
decisions. Upon the director 's initiative or in response to a request by a
water system, the director may modify the approval of the source water
treatment plans under paragraph (B)(2) of this rule, or maximum permissible
lead and copper concentrations for finished water entering the distribution
system under paragraph (B)(4) of this rule. A request for modification by a
system shall be in writing, explain why the modification is appropriate, and
provide supporting documentation. The director may modify the approval where
the director concludes that such change is necessary to ensure that the system
continues to minimize lead and copper concentrations in source water at the
entry point to the distribution system. A revised approval shall be made in
writing, set forth the new treatment requirements, explain the basis for the
director 's decision, and provide an implementation schedule for completing the
treatment modifications.
