F. For solid waste disposal facilities
regulated under Part III (9VAC20-81-100 et
seq.), site hydrogeologic and geotechnical reports by professional geologist or
professional engineer.
1. The site
investigation for a proposed landfill facility shall provide information
regarding the geotechnical and hydrogeologic conditions at the site to allow a
reasonable determination of the usefulness of the site for development as a
landfill. The geotechnical exploration efforts shall be designed to provide
information regarding the availability and suitability of onsite soils for use
in the various construction phases of the landfill including liner, cover,
drainage material, and cap. The hydrogeologic information shall be sufficient
to determine the characteristics of the uppermost aquifer underlying the
facility. Subsurface investigation programs conducted shall meet the minimum
specifications here.
a. Borings shall be
located to identify the uppermost aquifer within the proposed facility
boundary, determine the ability to perform groundwater monitoring at the site,
and provide data for the evaluation of the physical properties of soils and
soil availability. Borings completed for the proposed facility shall be
sufficient in number and depth to identify the thickness of the uppermost
aquifer and the presence of any significant underlying impermeable zone in the
waste management boundary. Impermeable zone shall not be fully penetrated
within the anticipated fill areas, whenever possible. The number of borings
shall be at a minimum in accordance with Table 5.1 as follows:

b.
The department reserves the right to require additional borings in areas in
which the number of borings required by Table 5.1 is not sufficient to describe
the geologic formations and groundwater flow patterns below the proposed solid
waste disposal facility.
c. In
highly uniform geological formations, the number of borings may be reduced, as
approved by the department.
d. The
borings shall employ a grid pattern, wherever possible, such that there is, at
a minimum, one boring in each major geomorphic feature. The borings pattern
shall enable the development of detailed cross sections through the proposed
landfill site.
e. Subsurface data
obtained by borings shall be collected by standard soil sampling techniques.
Diamond bit coring, air rotary drilling, or other appropriate methods, or a
combination of methods shall be used as appropriate to characterize competent
bedrock. The borings shall be logged from the surface to the lowest elevation
(base grade) or to bedrock, whichever is shallower, according to standard
practices and procedures. In addition, the borings required by Table 5.1 shall
be performed on a continuous basis for the first 20 feet below the lowest
elevation of the solid waste disposal facility or to the bed rock. Additional
samples as determined by the professional geologist or professional engineer
shall be collected at five-foot intervals thereafter.
f. Excavations, test pits, and geophysical
methods may be employed to supplement the soil boring investigation.
g. At a minimum, four of the borings shall be
converted to water level observations wells, well nests, piezometers, or
piezometer nests to allow determination of the rate and direction of
groundwater flow across the site. All groundwater monitoring points or water
level measurement points shall be designed to allow proper abandonment by
backfilling with an impermeable material. The total number of wells or well
nests shall be based on the complexity of the geology of the site.
h. Field analyses shall be performed in
representative borings to determine the in situ hydraulic conductivity of the
uppermost aquifer.
i. All borings
not to be utilized as permanent monitoring wells, and wells within the active
solid waste disposal area, shall be sealed and excavations and test pits shall
be backfilled and properly compacted to prevent possible paths of leachate
migration. Boring sealing procedures shall be documented in the hydrogeologic
report.
2. The
geotechnical and hydrogeologic reports shall at least include the following
principal sections:
a. Field procedures.
Boring records and analyses from properly spaced borings in the facility
portion of the site. Final boring logs shall be submitted for each boring,
recording soils or rock conditions encountered. Each log shall include the type
of drilling and sampling equipment, date the boring was started, date the
boring was finished, a soil or rock description in accordance with the United
Soil Classification System or the Rock Quality Designation, the method of
sampling, the depth of sample collection, the water levels encountered, and the
Standard Penetration Test blow counts, if applicable. Boring locations and
elevations shall be surveyed with a precision of 0.01 foot. At least one
surveyed point shall be indelibly marked by the surveyor on each well. All
depths of soil and rock as described within the boring log shall be corrected
to National Geodetic Vertical Datum, if available.
b. Geotechnical interpretations and report
including complete engineering description of the soil units underlying the
site.
(1) Soil unit descriptions shall include

discussed.
(2) Soil units that are
proposed for use as a drainage layer, impermeable cap, or impermeable liner
material shall be supported by laboratory determinations of the remolded
permeability. Remolded hydraulic conductivity tests require a Proctor
compaction test (ASTM D698) soil classification liquid limit, plastic limit,
particle size distribution, specific gravity, percent compaction of the test
sample, remolded density and remolded moisture content, and the percent
saturation of the test sample. Proctor compaction test data and hydraulic
conductivity test sample data shall be plotted on standard moisture-density
test graphs.
(3) The geotechnical
report shall provide an estimate of the available volume of materials suitable
for use as liner, cap, and drainage layer. It shall also discuss the
anticipated uses of the onsite materials, if known.
c. Hydrogeologic report.
(1) The report shall include water table
elevations, direction, and calculated rate of groundwater flow and similar
information on the hydrogeology of the site. All raw data shall be submitted
with calculations.

shall contain a discussion of field test procedures and results, laboratory
determinations made on undisturbed samples, recharge areas, discharge areas,
adjacent or areal usage, and typical radii of influence of pumping
wells.
(3) The report shall also
contain a discussion of the regional geologic setting, the site geology, and a
cataloging and description of the uppermost aquifer from the site investigation
and from referenced literature. The geologic description shall include a
discussion of the prevalence and orientation of fractures, faults, and other
structural discontinuities, and presence of any other significant geologic
features. The aquifer description shall address homogeneity, horizontal and
vertical extent, isotropy, the potential for groundwater remediation, if
required, and the factors influencing the proper placement of a groundwater
monitoring network.
(4) The report
shall include a geologic map of the site prepared from one of the following
sources as available, in order of preference:
