Resumes of key personnel for each project will be provided during project planning.   2.0 GEOTECHNICAL SERVICES TEMSG offers a comprehensive range of geotechnical services as outlined under Scope of Services (Section 1.2). These services are available to our clients throughout the various phases of a project, from site selection and project feasibility evaluation, through planning, design and construction. TEMSG has a commitment to provide Geotechnical consulting services with a high degree of professional excellence and proficiency. Our geotechnical consulting services are performed by a professional technical staff and/or consultants which includes geotechnical engineers, engineering geologists, geophysicists, environmental scientists, material testing engineers, field technicians, and civil engineers.  2.1  Geotechnical Studies This activity normally requires the combined expertise of our geotechnical engineers and engineering geologists, and may range in scope from feasibility-level studies intended to validate project concepts to more comprehensive design-phase geotechnical investigations. These studies describe and depict subsurface conditions for construction of different types of engineering structures. Working with other design professionals, the project team performs the appropriate subsurface explorations, testing and analyses. Based on the obtained data, we provide recommendations and design criteria for earthwork, structural support, selection of materials, and other elements of the project which depend on subsurface conditions. 2.2  Geologic Studies TEMSG provides geologic studies both as a part of geotechnical engineering studies and as individual or component geologic investigations. Typical studies have included assessments of rock units to verify suitability of manufactured slopes and identify excavation characteristics; stability analyses and erosion potential for natural slopes and coastal bluffs; subsidence potential evaluations; and studies to determine the past, present, and probable future occurrence of groundwater. TEMSG professionals can identify and characterize sites located within officially designated State of California and local County geologic hazard zones for active earthquake faults, liquefaction potential, landslide potential, and subsidence. Continuous professional development assures clients that hazard zone investigations are performed according to the latest technical guidelines and procedures, thus minimizing project delays and future risks. The scope of studies provided ranges from field reconnaissances to more complex evaluations of geologic conditions using multiple subsurface and remote sensing techniques. These include drilled bore holes, large-diameter shafts for downhole observations, direct push exploration methods, stereoscopic aerial photographic analysis, and geophysical methods. 2.3  Seismic Risk Analyses Most projects in seismically active areas such as California normally demand engineering mitigation for potential strong ground shaking. Utilizing the latest available data and analysis tools, we provide design parameters for ground motion according to the desired hazard level, according to deterministic or probabilistic models. Site classification studies and seismic design coefficient determinations are also performed, meeting the needs of the latest adopted edition of the Uniform Building Code and upcoming International Building Code. 2.4  Municipal Services Our staff possesses considerable experience providing geotechnical, geologic, engineering, and material testing support to municipal agencies.

Geophysical surveys can extend one-dimensional borehole data into two- and three-dimensional depictions of the subsurface. Geotechnical investigations can include applied geophysical methods to directly measure certain soil and rock engineering properties, as well as quantitatively evaluate site response in seismically active regions. Environmental investigations utilize geophysical means to detect buried objects, delineate contaminant migration pathways, and map the lateral extent of landfills and pits. Because most geophysical methods are non-destructive and use small, portable equipment, it is possible to collect subsurface data in areas of difficult terrain or at already-developed sites that are not suitable for traditional drill-and-sample methods. The selection of the appropriate survey depends on the physical characteristics of the site and the type of data sought. TEMSG conducts all exploration, testing, and monitoring programs utilizing trained operators and qualified professionals experienced in the selected method.  4.1  Seismic Methods The velocities and/or amplitudes of compressional and shear waves in soil and rock can be measured to deduce a number of important engineering properties. Exploration and construction monitoring services include the following: Seismic Refraction & Reflection Surveys: Utilizing state-of-the-art multi-channel digital equipment, these survey techniques can rapidly and inexpensively determine depths to bedrock or groundwater, map buried subsurface topography, and assist in locating buried fault planes. Refraction surveys allow TEMSG to supply project owners and contractors with vital information regarding rippability of bedrock or cemented alluvial units, using both published and proprietary correlations developed through years of experience. Downhole Seismic Surveys: The same tools used for surface refraction surveys can be used to generate vertical profiles of sonic wave velocities in drilled boreholes. Borehole shear wave measurements are the most accurate and precise means of assessing site stiffness in accordance with the latest adopted building codes. The availability of the seismic piezo-cone also allows TEMSG to perform assessments in Cone Penetration Test (CPT) soundings. Blast & Vibration Monitoring: Blasting and quarrying operations, pile driving, and heavy equipment passage can generate ground vibrations potentially damaging to nearby improvements. Monitoring can assure that vibrations are maintained within threshold values to prevent undue hazard or liability to project operators.  4.2  Magnetic Surveys Portable proton precession magnetometers offer a quick, efficient means of locating buried ferromagnetic objects such as underground storage tanks, steel drums, pipelines, and wells. Magnetic surveys are a common part of comprehensive environmental investigations of large areas, where surface maps of potential targets are needed prior to more-detailed subsurface drilling and sampling assessments.  4.3 Electrical Resistivity Resistivity methods in general rely on measurements of the electric potential differences across an array of electrodes inserted into the ground. By incrementally changing the geometry of the array, a two-dimensional vertical model of the subsurface is generated. The method is especially suitable for delineation of fluid-phase contaminants in shallow subsurface aquifers and identifying lateral changes in water quality. Geotechnical and geologic investigations may utilize this method to help define depths to bedrock or identify possible sheared zones associated with active faults.  4.4  Ground Penetrating Radar Ground penetrating radar (GPR) provides a two-dimensional profile along the track of a transceiver pulled along the ground surface. The method allows for precise soil profiling between subsurface boreholes and trenches. Environmental and geotechnical investigations faced with detecting buried non-metallic objects, unknown fills, voids, or disturbed ground are candidates for this method. TEMSG is committed to staying abreast of the latest uses for this increasingly capable tool, including uses to identify active faults in younger alluvium, pavement analysis, and spring or sinkhole detection.  4.5  Electromagnetic Induction Profiling Man-made electric currents can induce small currents in the ground or in buried objects, currents that will differ depending upon the conductivity and magnetic susceptibility of the subsurface. The induced currents produce magnetic fields that can be measured from the surface using small hand-held equipment, such that large areas can be surveyed in a day. The uses for this technique are similar to those listed for magnetic or resistivity surveys.  4.6  Downhole Geophysical Logging TEMSG professionals are experienced with the tools, techniques, and interpretation of geophysical logs that can be applied to exploratory soil and rock boreholes, CPT soundings, and water well development. Downhole logs can offer substantial enhancements to traditional discrete sampling or coring when continuity of data is vital or geometric orientation is important. Common geophysical surveys include electrical resistivity, spontaneous potential, natural gamma radiation, and neutron backscatter. Relatively new methods exist to directly view, pick, and analyze rock strata and discontinuity orientations by means of borehole image systems and acoustic logs. Many of these systems allow for remote processing and statistical analysis of the image data to complement surface measurements made on recovered samples.  5.0 ENVIRONMENTAL SERVICES Environmental Services are provided by our constituent firm, Remediation Sciences, Inc. (RSI), which is a full-service environmental consulting and services company dedicated to the detection, identification and remediation of pollution problems resulting from the use, handling, storage, and disposal of hazardous chemicals and toxic substances.

RSI's personnel maintain constant contact with governmental regulations that impact the clients' operations.  5.1  Scope of Environmental Services Remediation Sciences, Inc. Provides a full spectrum of environmental services from initial site assessments to remediation and final closure. RSI offers the following services: Phase l and Phase ll Environmental Site Assessments Drilling and Installation of Monitoring Wells Underground Storage Tank Removals Neutron Logging and Subsurface Mapping, utilizing U.S. Patent # 4754136 Verification of Naturally Occurring "Passive Remediation" Soil and Groundwater Investigations Groundwater Remediation Contaminated Soil Remediation Bioremediation Soil Sampling Third Party Evaluations The RSI staff members are experts in the remediation of contaminated soil and groundwater. RSI's personnel have carried out numerous remediation projects with outstanding results, including the above-ground treatment of contaminated soil using bioremediation techniques and in-situ cleanup of intact soils. RSI has designed and implemented efficient, cost effective vapor extraction, air sparging, bioventing, and pump-and-treat systems for soil and groundwater remediation projects. RSI personnel are also pioneers of a process that mechanically precesses excavated soils, effectively bioremediating contaminated soils in as little as two weeks. When bioremediation methods are specifically required, RSI utilizes naturally-occurring microorganisms (not genetically engineered) that are specially screened and cultivated for their petroleum hydrocarbon-degrading capabilities. The strains of bacteria used have the ability to function in low-oxygen environments, and are also effective in highly saline (up to 20% salt) and high temperature environments (up to 140°F). RS's goal is always to recommend and implement remediation systems that most effectively serve client's needs in a professional, timely, cost-effective and safe manner.  5.2  Specialized Environmental Services Modified Bioremediation Process RSI's method of modified bioremediation has proven more effective than conventional land farming techniques. In this process, untreated materials are loaded into a soil shredder and carried to the processing area where they are ground into small particles, separating out construction debris and larger rocks. During the break-down process, prior to exit, the soil is inoculated with biomaterials from RSI's uniquely calibrated spray system. The treated soils are then stockpiled on-site and maintained at optimum conditions until remediation is complete. Interim and final confirmation samples are collected to verify biodegradation of the contaminants and to monitor nutrient and moisture conditions. When targeted clean-up levels are reached, remediated soils can be used as on-site fill material or transported to a Class III landfill. The advantage of this bioremediation process over the usual landfarming technique is that by grinding the soil into small, homogeneous particles, the surface area on which the bacteria can act is greatly increased, thereby effecting more expeditious and thorough digestion of contaminant hydrocarbons and reducing the remediation time in some cases to as little as two weeks. Neutron Logging and Subsurface Mapping RSI's subsurface mapping and monitoring technology was developed in the early 1980's and patented in 1988. RSI personnel have applied this unique patented technology (U.S. Patent #4754136) to afford clients significant cost savings at facilities where conditions are such that subsurface contamination can be left in place and allowed to "passively remediate". The application of the subsurface mapping and monitoring system involves a modified well-logging technique; neutron logging is combined with headspace vapor analyses. Absorbed phase leading or residual staining from previous leakage of petroleum hydrocarbons is logged, or mapped, using neutron backscatter logging in vadose zone monitoring wells. Once discovered, contaminants are identified by sampling the vapors at depths demonstrating elevated hydrogen levels. The collected vapors are then analyzed by gas chromatography, allowing component level identification of extremely high sensitivity. The vapors are also analyzed for fixed gases to verify the natural biodegradation or "passive remediation" of the petroleum hydrocarbon contamination by the indigenous microorganisms. RSI principals are industry pioneers in this passive approach, sharing in the development and application for in-situ measurement of such naturally occurring processes. Furthermore, the RSI test system is nondestructive and can be periodically re-applied to the site to verify the stability and on-going natural biodegradation of the subsurface contaminant plume. Natural biodegradation eliminates the need for costly excavation methods that might be required using conventional techniques. Over the past five years, members of the RSI staff have received closure on numerous sites in California and Nevada where mitigation efforts fall within the parameters of the RSI mapping and biodegradation protocols.  5.3  Typical Environmental Projects Neutron Logging The patented RSI system was utilized at a privately owned service station in Southern California. Other nationally known engineering firms had determined that excavation of the site must be incorporated into the mitigation measures. RSI personnel determined that existing anomalies on the site were, in fact, already naturally biodegrading, and that no excavation and no additional mitigation of any kind would be necessary at the site. Instead, the work of naturally occurring bacteria was monitored as they alone caused degradation of subsurface contaminants. No additional costs were incurred and this site was fully approved as mitigated. Modified Bioremediation Upon removal of two USTs at an Orange County public facility, it was determined that diesel and waste oil-contaminated soil required remediation. Diesel fuel contamination was detected at concentrations as high as 7,500 ppm TPH. RSI personnel proposed bioremediation utilizing the soil shredder. After only fifteen days, six samples were collected from the treated stockpile and analyzed for TPH using DOHS Test Method 8015M for diesel fuel and motor oil. One of the six samples showed a result of 11 ppm for diesel fuel. The remaining five samples were below the detection limit of 10 ppm. Treated soils were used on-site for backfill following the granting of closure from the lead regulatory agency  6.0 CONCLUSIONS TEMSG has a commitment to provide Geotechnical, Geological, Municipal, Material Testing, and Environmental Consulting services with a high degree of professional excellence and proficiency.
