' 4.0 CONCLUSIONS <br /> The following conclusions are formulated based on review of available data and results of the RBCA <br /> ' analysis performed at the site <br /> • Petroleum hydrocarbon and MTBE concentrations in soils and groundwater detected following <br /> ' remediation efforts at the site do not pose a significant risk to daily site occupants under <br /> commercial/industrial land use, <br /> • Petroleum hydrocarbons and MTBE concentrations in soils and groundwater detected following <br /> remediation efforts at the site do not pose a significant risk to existing residential receptors at offsite <br /> ' locations, <br /> Petroleum hydrocarbons and MTBE concentrations in soils detected following remediation efforts at <br /> the site do not pose a significant risk to future construction workers at the site, and <br /> ' Prior to initiation of construction work, an appropriate health and safety plan should be developed to <br /> ensure construction worker health and safety <br /> 5.0 REFERENCES <br /> ' Association for the Environmental Health of Soils (AEHS), 1997, Exposure Pathway Modeling for RBCA, <br /> 7th Annual West Coast Conference on Contaminated Soils and Groundwater March <br /> American Society for Testing and Materials (ASTM), 1995 Standard Guide for Risk-Based Corrective <br /> Action Applied at Petroleum Release Sites, E 1739-95 <br /> ' ASTM, 1998 Standard Provisional Guide for Risk-Based Corrective Action, PS 104-98 <br /> California Department of Toxic Substance Control(DTSC), 1994 Califorma Cancer Potency Factors <br /> ' Update Office of Environmental Health Hazard Assessment State of California Environmental <br /> Protection Agency (Cal-EPA) November 1, 1994 <br /> ' DTSC, 1999 Preliminary Endangerment Assessment Office of Environmental Health Hazard Assessment <br /> State of California Environmental Protection Agency(Cal-EPA) <br /> Domencio, P A, 1987, An Analytical Model for Multidimensional Transport of a Decaying Contaminant <br /> Species,Journ Hydrol, v 91, p 49-58 <br /> ' ETIC Environmental Engineering„ Inc (ETIC),2000 Confirmation Soil Baring Results and Request for <br /> Case Closure, 2000 1605 South Eldorado Street, Stockton, CA <br /> GSI, 1995 Tier I and Tier Il R13CA Spreadsheet System, Version 1 0 <br /> ,GSI, 1997 Tier I and Tier 11 RBCA Spreadsheet System, Version 101 <br /> GSI, 1999 RBCA Toolkit for Chemical Releases <br /> Heath, R C , 1989 Basic Ground-Water Hydrology Published by the US Government Printing Office for <br /> ' the USGS, Third Edition <br /> ' 15 <br />
