Design and Operation
PURPOSE: This rule pertains to the design
and operation of a utility waste landfill.
(1) General Provisions. This rule is intended
to provide for utility waste landfill operations
that will have minimal impact on the environment. The rule sets forth requirements
and the method of satisfactory compliance to
ensure that the design, construction and operation of utility waste landfills will protect the
public health, prevent nuisances and meet
applicable environmental standards. The
requirement subsections contained in this rule
delineate minimum levels of performance
required of any utility waste landfill operation. The satisfactory compliance subsections
are presented as the authorized methods by
which the objectives of the requirements can
be realized. The satisfactory compliance subsections are based on the practice of landfilling utility waste. If techniques other than
those listed as satisfactory compliance in
design or operation are used, it is the obligation of the utility waste landfill owner/operator to demonstrate to the department in
advance that the techniques to be employed
will satisfy the requirements. Procedures for
the techniques shall be submitted to the
department in writing and approved by the
department in writing prior to being
employed. Notwithstanding any other provision of these rules, when it is found necessary
to meet objectives of the requirement subsections, the department may require changes in
design or operation as the condition warrants.
This rule applies to new utility waste landfill
construction and operating permits issued on
or after the effective date of this rule.

5. The owner/operator shall specify in
the operating record one (1) or more of the
following statistical methods to be used in
evaluating groundwater monitoring data for
each monitoring constituent. The statistical
test chosen shall be conducted separately for
each constituent—

(ANOVA) followed by multiple comparisons
procedures to identify statistically significant
evidence of contamination. The procedure
shall include estimation and testing of the
contrasts between each downgradient well’s
mean and the upgradient means for each
parameter;
B. An ANOVA based on ranks followed by multiple comparisons procedures to
identify statistically significant evidence of
contamination. The procedure shall include
estimation and testing of the contrasts
between each downgradient well’s median
and the background medians for each parameter;
C. A confidence interval procedure in
which an interval for each parameter in each
downgradient well is constructed around the
mean/median of the particular well’s data or
data residuals and compared to the
mean/median of pooled background well
data;
D. A prediction interval procedure in
which an upper prediction limit for an interval for each parameter in each well is compared to subsequently obtained values from
the same well;
E. A prediction interval procedure in
which an upper prediction limit for an interval for each parameter constructed on the
pooled background well data or data residuals is compared to subsequently obtained values from each downgradient well;
F. A tolerance interval procedure in
which an upper tolerance limit for an interval
for each parameter’s pooled background well
data is compared to each downgradient well’s
concentration values;
G. A multicomparison procedure utilizing any recommended U.S. Environmental
Protection Agency combinations of intra-well
and inter-well procedures for each parameter;
H. A control chart approach meeting
the
performance
standards
of
part
(11)(C)5.J.(III), that gives control limits for
each parameter;
I. A different statistical test method
that meets the performance standards of subparagraph (11)(C)5.J. of the rule. The owner/operator must submit the statistical test
method to the department for approval before
the use of the alternative test; and
J. Any statistical method chosen
under paragraph (11)(C)5. of this rule shall
comply with the following performance standards, as appropriate:
(I) The statistical method used to
evaluate groundwater monitoring data shall
be appropriate for the distribution of the concentration data for the chemical parameters
or hazardous constituents. If the distribution
of the concentration data for the chemical
parameters or hazardous constituents is
shown by the owner/operator to be inappropriate for a normal data distribution theory
test, then the data should be transformed or a
distribution-free (nonparametric) theory test
should be used. If the concentration data distributions for the constituents of each well
differ, more than one (1) statistical method
will be needed;
(II) If an individual well comparison procedure is used to compare an individual compliance well constituent concentration
with background constituent concentration or
a groundwater protection standard, the test
shall be done at a Type I error level no less
than 0.01 for each testing period. If a multiple comparisons procedure is used, the Type
I experiment-wide error rate for each testing
period shall be no less than 0.05, however,
the Type I error of no less than 0.01 for individual well comparisons shall be maintained.
This performance standard does not apply to
tolerance intervals, prediction intervals or
control charts;
(III) If a control chart approach is
used to evaluate groundwater monitoring
data, the specific type of control chart and its
associated parameter values shall be protective of human health and the environment.
The selection of this method shall be determined after considering the number of samples in the background data base, the data
distribution, and the range of the concentration values for each constituent of concern;
(IV) If a confidence interval, tolerance interval or a prediction interval is used
to evaluate groundwater monitoring data,
then the level of confidence for each interval,
and the percentage of the population that each
interval contains, shall be protective of
human health and the environment. Selection
of one (1) or more of these methods shall be
determined after considering the number of
samples in the background data base, the data
distribution, and the range of the concentration values for each constituent of concern;
(V) The statistical method shall
account for data below the limit of detection
with one (1) or more statistical procedures
that are protective of human health and the
environment. Any practical quantization limit that is used in the statistical method shall be
the lowest concentration level that can be reliably achieved within specified limits of precision and accuracy during routine laboratory
operating conditions that are available to the
facility; and
(VI) If necessary, the statistical
method shall include procedures to control or
correct for seasonal and spatial variability as
well as temporal correlation in the data.
6. Response to statistical analysis.
A. If the comparison for the upgradient wells shows a statistically significant
increase (or pH change) over background, the
owner/operator shall submit this information
to the department.
B. If the comparisons for downgradient wells show a statistically significant
increase (or pH change), resulting from the
landfill, over background, the owner/operator
shall within ninety (90) days of the last sampling event obtain additional groundwater
samples from those downgradient wells
where a statistically significant difference
was detected, split the samples in two (2),
and obtain analyses of all additional samples
to determine whether the significant statistical difference was a result of laboratory error.
C. If the additional samples show a
statistically significant increase (or pH
change) over background, the owner/operator
must demonstrate to the department within
ninety (90) days that a source other than the
utility waste landfill caused the contamination
or that the statistically significant increase
resulted from an error in sampling, analysis,
statistical evaluation or natural variation. If
the owner/operator cannot make this demonstration to the department, the owner/operator shall submit a plan to the department for
a groundwater assessment monitoring program and implement the program as
described in subparagraphs (11)(C)6.D.
through H. of this rule. The plan shall specify the following:
(I) The number, location and depth
of wells;
(II) Sampling and analytical methods for the monitoring parameters listed in
Appendix I of this rule on a quarterly basis;
(III) Evaluation procedures, including any use of previously gathered groundwater quality information;
(IV) The rate and extent of migration of the contaminant plume in the groundwater; and
(V) The concentrations of the contaminant plume in the groundwater.
D. After obtaining the results from
the initial or subsequent sampling events
required in subparagraph (9)(C)6.D. the
owner/operator shall—
(I) Within fourteen (14) days, notify the department and place a notice in the
operating record identifying the constituents
that have been detected;
(II) Within ninety (90) days, and on
a quarterly basis after that, resample all wells
and conduct analysis for all constituents listed in Appendix I to this rule and notify the
department of the constituent concentrations.

sampled (background and downgradient)
shall be collected and analyzed during these
sampling events;
(III) Establish background concentrations for any new constituents detected
during subsequent monitoring events; and
(IV) Establish groundwater protection standards for all new constituents detected during subsequent monitoring events.
E. If the concentrations of all constituents listed in Appendix I to this rule are
shown to be at or below background levels as
established in paragraph (11)(C)3. of this rule

owner/operator may reinstate detection monitoring at the utility waste landfill as specified
under subparagraph (11)(C)3.C. of this rule.
F. If the concentrations of any constituents listed in Appendix I of this rule are
above background values, but all concentrations are below the groundwater protection
standard established under subparagraph
(11)(C)6.D. of this rule using the statistical
procedures in paragraph (11)(C)5. of this
rule, the owner/operator shall notify the
department and the department may require
the owner/operator to—
(I) Continue assessment monitoring; or
(II) Develop a corrective measures
assessment, or both.
G. If one (1) or more constituents listed in Appendix I of this rule are detected at
levels above the groundwater protection standard as established under subparagraph
(11)(C)6.D., the owner/operator shall—
