(A) Site characterization for employment of
the recompacted soil liner requirement.
(1) A
recompacted soil liner, as described in paragraph (F)(5)(a) of rule
3745-400-07 of the
Administrative Code, is required for all unfilled areas in a
facility except
when the in situ or added geologic material separating the uppermost
aquifer
system from the bottom of the
leachate collection system in unfilled areas
meets the criteria in paragraphs (A)(2) and (A)(3) of this rule and one of the
following:
(a) When, in a facility that was in
operation or under construction on September 30, 1996, the in situ or added
geologic material separating the uppermost aquifer system from all placed
debris meets the criteria in paragraphs (A)(2) and (A)(3) of this
rule.
(b) When the unfilled areas
of a
facility that was in operation or under construction on September 30, 1996

constructed on existing placed
debris in accordance with paragraph (F)(5)(d) of
rule
3745-400-07 of the
Administrative Code.
(c) When the
unfilled areas of a facility that was in operation or under construction on
September 30, 1996 meet the requirements of paragraph (A)(1) of this rule and a
minimum fifteen foot horizontal separation exists between existing placed

cm/sec.
(3) Added
geologic material, if any, shall meet the requirements in paragraph (F)(5)(b)
of rule
3745-400-07 of the
Administrative Code.
(B)

ground water monitoring requirement. A
ground
water monitoring well system, as described in paragraph (A) of rule
3745-400-10 of the
Administrative Code, is required for a
facility accepting
debris on or after
September 30, 1996, unless all of the following conditions are met:
(1) The limits of debris placement are not
within five feet of the uppermost aquifer system.
(a)(2) The
five feet of isolation material between the
uppermost

shall have
has
a permeability equivalent to at least five feet of soil with a maximum
permeability of 1 x 10
-6 cm/sec
.
(b) None
and none of the geological material
to be included as the minimum five feet of isolation
material shall have
has a permeability
greater than 1 x 10-5 cm/sec.
.
(2)(3) The limits of
debris placement are not within the boundaries of a sole source aquifer
designated by the
Administrator
administrator of the United States environmental
protection agency under the "Safe Drinking Water Act", 88 Stat.
1660 (1974),
42 U.S.C.
300F.
(3)(4) The limits of
debris placement are not within the limits of any unconsolidated aquifer
systems delineated on the Ohio department of natural resources ground water
resource maps as yielding at least one hundred gallons per minute.
(4)(5)
The limits of debris placement are not within the limits of an Ohio EPA
endorsed wellhead protection area or source water protection area for ground
water.
(5)(6) The limits of
debris placement are not within one thousand feet of a public water supply well
in a public water supply well field delivering less than seventy-five thousand
gallons per day.

debris placement are not within one thousand five hundred feet of a public
water supply well in a public water supply well field delivering seventy-five
thousand or more gallons per day.
(7)(8) The limits of
debris placement are not within one thousand feet of any water supply well or
developed spring.
[Comment: New facilities required to
have ground water monitoring must implement the system prior to accepting
debris for disposal {see paragraph (R)(4) of rule 3745-400-11 of the
Administrative Code}.]
(C) Site characterization report.
(1) The purpose of the site characterization
report is to have a
qualified ground water scientist provide documentation that
the standards established in rule
3745-400-06 of the
Administrative Code
(prohibited locations),
paragraph (A) of this rule
(liner), and
paragraph (B) of this rule
(ground water monitoring)
are met and that the
ground water monitoring system as outlined in
rule
3745-400-10 of the
Administrative Code is capable of determining the quality of the
ground water
under the
facility.
The
The site characterization
report is a part of the facility design plan as outlined in paragraph (A) of
rule 3745-400-07 of the
Administrative Code. The owner or operator of a new facility shall submit
the
a site
characterization report in narrative form with
the first license application.
using such maps and cross sections as to clearly convey
the nature of the site and the hydrogeology beneath the facility. If the
facility meets the standards in paragraph (A) of this rule, the hydrogeologic
investigation may be conducted and described in phases.
The site characteristics shall be
documented in a narrative report using such maps and cross sections as to
clearly convey the nature of the site and the hydrogeology beneath the
facility. If the facility meets the standards in paragraph (A) of this rule,
the hydrogeologic investigation can be conducted in phases, of which each phase
shall be described in the site characterization report.
(2) The site characterization
report shall contain documentation that the ground water scientist meets the
qualifications of a qualified ground water scientist as defined 3745-400-01 of the Administrative
Code.
(3) The
qualified
ground water scientist shall
make
prepare and sign a
written final summary as to whether the standards
established in rule
3745-400-06 of the
Administrative Code
(prohibited locations),
paragraph (A) of this rule
(liner), and
paragraph (B) of this rule
(ground water
monitoring) are met
. The final summary
shall state
by stating each standard and
whether the standard has been met.
The final summary
shall be signed by the qualified ground water scientist.
(4) The site characterization report shall
contain the following publicly available information to support the final
summary:
(a) An applicable map prepared under
the "National Flood Insurance Act of 1968" 82 Stat.
572,

facility is located with respect to the one hundred year
flood plain of a watercourse. If no such map has been prepared for the
watercourse, the location of the
facility and the delineation of the one
hundred year flood plain shall be shown on a plan sheet
. The

boundaries of the one-hundred-year flood plain of a watercourse
shall be determined by the
applicant for a
license based upon a design storm of seven inches of precipitation in
twenty-four hours and upon standard methodologies set forth in "Urban Hydrology
for Small Watersheds" and section 4 of the "National Engineering Hydrology
Handbook."
[Comment: Note that the above mentioned maps also include flood
plains not associated with a watercourse. Location in such flood plains is not
