In addition, the borings required by Table 7.1 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 registered geologist or 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 ground water flow across the site. All ground water 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 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 estimates of soil unit thickness, continuity across the site, and genesis. Laboratory determination of the soil unit's physical properties shall be 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 should 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 should also discuss the anticipated uses of the on-site materials, if known.
c. Hydrogeologic report.
(1) The report shall include water table elevations, direction and calculated rate of ground water flow and similar information on the hydrogeology of the site. All raw data shall be submitted with calculations.
(2) The report 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 should address homogeneity, horizontal and vertical extent, isotropy, the potential for ground water remediation, if required, and the factors influencing the proper placement of a ground water 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:
(a) Site specific mapping prepared from data collected during the site investigation;
(b) Published geologic mapping at a scale of 1:24,000 or larger;
(c) Published regional geologic mapping at a scale of 1:250,000 or larger; or
(d) Other published mapping.
(5) At least two generally orthogonal, detailed site specific cross sections, which shall sufficiently describe the geologic formations identified by the geologic maps prepared in accordance with subdivision 2 c (4) of this subsection at a scale which clearly illustrates the geologic formations, shall be included in the hydrogeologic report. Cross sections shall show the geologic units, approximate construction of existing landfill cells base grades, water table, and surficial features along the line of the cross section. Cross section locations shall be shown on an overall facility map.
(6) Potentiometric surface maps for the uppermost aquifer which sufficiently define the ground water conditions encountered below the proposed solid waste disposal facility area based upon stabilized ground water elevations. Potentiometric surface maps shall be prepared for each set of ground water elevation data available. The applicant shall include a discussion of the effects of site modifications, seasonal variations in precipitation, and existing and future land uses of the site on the potentiometric surface.
(7) If a geological map or report from either the Department of Mines, Minerals, and Energy or the U.S. Geological Survey is published, it shall be included.
F. For solid waste management facilities regulated under Part VI (9VAC20-80-320 et seq.) of this chapter:
1. A cataloging and description of aquifers, geological features or any similar characteristic of the site that might affect the operation of the facility or be affected by that operation.
2. If a geological map or report from either the Department of Mines, Minerals, and Energy or the U.S. Geological Survey is published, it shall be included.
G. For sanitary landfills, a VDOT adequacy report prepared by the Virginia Department of Transportation. As required under § 10.1-1408.4 A 1 of the Code of Virginia, the report will address the adequacy of transportation facilities that will be available to serve the landfill, including the impact of the landfill on the local traffic volume, road congestion, and highway safety.
H. For sanitary landfills, a Landfill Impact Statement (LIS).
1. A report must be provided to the department that addresses the potential impact of the landfill on parks, recreational areas, wildlife management areas, critical habitat areas of endangered species as designated by applicable local, state, or federal agencies, public water supplies, marine resources, wetlands, historic sites, fish and wildlife, water quality, and tourism. This report shall comply with the statutory requirements for siting landfills in the vicinity of public water supplies or wetlands as recorded in §§ 10.1-1408.4 and 10.1-1408.5 of the Code of Virginia.
