(A) Leachate sampling and analysis.
Throughout the operation, closure, and post-closure care, the owner or operator
shall do the following:
(1) Sample and test
leachate in accordance with the following unless the facility was licensed and
operating on December 22, 2005, and was not required to have a leachate
monitoring system on that date. For the purposes of this rule, a "leachate
monitoring system" is any leachate collection system that includes sump risers
or other access that can be used for collecting samples of leachate.
(a) Sampling frequency.
(i)
An
The owner or
operator shall sample leachate at the facility at least annually.
(ii) If the owner or operator recirculates
leachate after
the effective date of this
rule
January 1, 2013, the owner or
operator shall sample leachate at the facility at least quarterly.
(b) Sampling locations.
(i) At least annually
an
the owner
or operator shall obtain at least one representative leachate sample from a
minimum of one sump collecting leachate from areas of the facility containing
disposed material. Within every five year period,
an
the owner or
operator shall obtain at least one representative leachate sample from each
sump collecting leachate from areas of the facility containing disposed
material.
(ii) At least quarterly
an
the owner
or operator that has recirculated leachate through a facility after
the effective date of this rule
January 1, 2013 shall obtain at least one
representative leachate sample from each sump capable of collecting leachate
from such areas of the facility receiving the recirculated leachate.
[Comment: The director or health
commissioner of the licensing authority may utilize authority under
section 3714.04 of the Revised Code to
specify different sampling locations and frequencies than required by this rule
as deemed appropriate.]
(c) Field analysis. During each leachate
sampling event,
an
the owner or operator shall measure the pH, specific
conductance, temperature, and turbidity for each sump from which a sample is
taken.
(d) Laboratory analysis.
(i)
An
The owner or
operator shall analyze each leachate sample for the parameters listed in rule
3745-400-21
of the Administrative Code.
(ii)
The practical quantitation limit (PQL) used for laboratory analysis shall be
the following:
(a) The lowest concentration
level that can be reliably achieved during routine laboratory operating
conditions that are reasonably available for the analytical method chosen by
the owner or operator, unless paragraph (A)(1)(d)(iii) of this rule
applies.
(b) Lower than the primary
drinking water standard for the parameter included in Chapter 3745-81 of the
Administrative Code, if one exists, and the secondary drinking water standard
for the parameter included in Chapter 3745-82 of the Administrative Code, if
one exists, unless paragraph
(A)(1)
(d)(ii)
(A)(1)(d)(iii) of this rule
applies.
(iii) If the
PQL does not comply with paragraph (A)(1)(d)(ii) of this rule
,
then an
the owner or operator shall do one of the following:
(a) Choose alternative sampling or analytical
procedures or choose an alternative analytical method that will result in a PQL
that complies with paragraph (A)(1)(d)(ii) of this rule and reanalyze the
sample or resample.
(b) Identify
and report interferences that prevent the use of a PQL meeting the requirements
of paragraph (A)(1)(d)(ii) of this rule and provide a written justification in
the leachate report why the use of another procedure or method in accordance
with paragraph (A)(1)(d)(iii)(a) of this rule is impractical.
(c) Conclude that the parameter has been
detected in leachate for the purpose of conducting ground water detection
monitoring in accordance with paragraph (B) of this rule.
(e) Submitting the sampling and
analysis results.
An
The owner or operator shall submit to the director and
approved board of
the health
commissioner of the
licensing authority the following information not later than seventy-five
days after each leachate sampling event:
(i)
The results of the field analysis required by paragraph (A)(1)(c) of this
rule.
(ii) The results of the
laboratory analysis of the parameters listed in rule
3745-400-21
of the Administrative Code in the same order as listed in rule
3745-400-21
of the Administrative Code.
(iii)
Identification of the leachate parameters required by paragraph (B) of this
rule to be monitored in ground water.
(iv) Quality control data used by the
laboratory to determine whether the analysis results are accurate.
(v) The method detection limits, PQLs, and
analysis methods used.
(vi) Forms
in the leachate sampling and analysis plan that were completed during leachate
sampling and analysis.
(2) Develop and comply with a leachate
sampling and analysis plan that contains the following:
(a) A description of the equipment,
procedures, and techniques to be used to sample and analyze leachate in
accordance with this rule. Sample collection, preservation, and handling
methods described in the plan shall provide for collection of representative
samples of leachate.
[Comment: An
The owner or operator is not required to include
references to specific laboratory analysis methods, specific method detection
limits, or specific practical quantitation limits in the leachate sampling and
analysis plan.]
(b) Blank
forms to be used to record the information obtained during leachate sampling
and analysis including at a minimum the following types of forms:
(i) Forms for recording field analysis
results and conditions encountered at the facility during a sampling
event.
(ii) Forms for recording the
chain of custody of leachate samples.
(B) Additional requirements to
monitor ground water for leachate parameters.
(1) The owner or operator of a facility with
a ground water monitoring system and a leachate monitoring system that can be
used for conducting the leachate sampling required by paragraph (A) of this
rule shall monitor ground water for parameters that have been detected in the
facility's leachate.
(2) If Ohio
EPA or the licensing authority has detected a parameter listed in rule
3745-400-21
of the Administrative Code through conducting sampling in accordance with
paragraph (A) of this rule with the exclusion of paragraph (A) (1)(d)(iii)(c),
Ohio EPA or the licensing authority may require that the owner or operator add
a parameter listed in rule
3745-400-21
of the Administrative Code that is detected by the Ohio EPA or the licensing
authority to the ground water monitoring parameter list.
(3) The owner or operator of a facility that
has a ground water monitoring system and does not have a leachate monitoring
system that can be used for conducting the leachate sampling required by
paragraph (A) of this rule shall monitor ground water for the parameters listed
in rule
3745-400-21
of the Administrative Code.
(4) The
owner or operator shall monitor ground water for the additional parameters
required by this rule in accordance with rule
3745-400-10
of the Administrative Code.
[Comment: The director or the health
commissioner of the licensing authority may utilize authority under
section 3714.04 of the Revised Code
should the addition of parameters required by this paragraph no longer be
determined appropriate.]
