Fabricated structures - A subsurface geological exploration shall be completed
for fabricated structures as described in this paragraph:
(1) For fabricated structures storing solid
manure.
Evaluate the suitability of the soil to
provide the appropriate load bearing strength for the proposed fabricated
structure by use of a soil survey or by a geological exploration conducted in
accordance with this rule. The director may require on-site subsurface
geological explorations depending on the soil survey, depth of the structure to
be installed below existing grade and type of structural loading of the
fabricated structure. The geological report shall meet the requirements in
paragraph (C) of this rule.
(2) For fabricated structures storing liquid
manure.
The subsurface geological exploration and report, described in paragraph (C) of this rule, shall be
completed under the supervision of
a professional geologist or
a professional engineer and shall be in
compliance with and describe the following:
(a) The subsurface geological exploration
shall include a minimum of three test pits or borings. The test pits or borings
must be at regular intervals and within a reasonable distance of the boundaries
of the proposed fabricated structure. Additional test pits or borings may be
required by the director,
the professional engineer, or
the professional geologist.
(b) The test pits or borings shall extend a
minimum of five feet below the planned bottom of the fabricated structure. In
addition, a representative number of test pits or borings shall extend deep
enough to determine if the fabricated structure meets the siting criteria from
the uppermost aquifer described in rule
901:10-2-02

shall evaluate the suitability of the soil to provide the appropriate load
bearing strength for the proposed fabricated structure as set forth in the
appendix to rule
901:10-2-05

subsurface geological exploration shall determine soil strength values so that
lateral earth pressures can be calculated as set forth in the appendix to rule
901:10-2-05
of the Administrative Code.
(g) The
subsurface geological exploration shall evaluate whether the proposed
fabricated structure is to be located within a karst area; and
(h) Ground water quality characteristics.
(i)
Ground water shall be sampled from a well
existing at the facility.
(ii)
If no well
exists as the facility, ground water shall be sampled from a well that is
nearby as approved by the department. If no nearby existing well is available
for sampling prior to construction of a new facility, then the director may
allow sampling prior to approval of stocking as described in paragraph (B)(4)
of rule
901:10-2-01
of the Administrative Code.
(iii)
A well
installed or otherwise approved for use to satisfy the requirements of this
rule, shall also be used to satisfy the annual ground water sampling and
analysis required by rule
901:10-2-08
of the Administrative Code.
(i) In the event that the director determines
that ground water monitoring shall be required to satisfy the requirements of
this rule or rule
901:10-2-02
of the Administrative Code, then a ground water monitoring program shall be
designed, installed, and implemented as approved by the director in a permit to
install and permit to operate.
(B)

Lagoons - A subsurface geological
exploration shall be completed for manure storage ponds or manure treatment
lagoons as described in this paragraph.

completed under the supervision of
a professional geologist or
a professional engineer, and shall be in compliance with and describe
the following:
(1) The subsurface
geological exploration shall include a minimum of four test pits or borings.
The test pits or borings must be at regular intervals and within a reasonable
distance of the boundaries of the proposed manure storage pond or manure
treatment lagoon. Additional test pits or borings may be required by the
director,
the professional engineer, or
the
professional geologist.

borings shall extend deep enough to determine if the manure storage pond or
manure treatment lagoon meets the siting criteria from the uppermost aquifer
described in rule
901:10-2-02
of the Administrative Code. Upon completion, any boring or pit used for
sampling shall be properly plugged and sealed. Any pit used for sampling that
is within the construction boundaries of the concentrated animal feeding
facility, the manure storage pond or the manure treatment lagoon shall be
restored by the addition of cohesive soil compacted in lifts no greater than
six inches;
(3) The classification
of the soil material shall be provided, as set forth in the appendix to this
rule;
(4) The in-situ hydraulic
conductivity of the soil material shall be determined, based on lab results,
within five feet below the planned bottom of the manure storage pond or manure
treatment lagoon;
(5) The
subsurface geological exploration shall evaluate the suitability of the soil
material to provide adequate sealing of the bottom of the manure storage pond
or manure treatment lagoon and construction of the planned embankments as
described in rule
901:10-2-06
of the Administrative Code;
(6) The
subsurface geological exploration shall evaluate whether the proposed manure
storage pond or manure treatment lagoon is to be located within a karst
area;
(7) Ground water quality
characteristics.
