STANDARD ENVIRONMENTAL RECORD SOURCES <br />A computer search of federal, state and regional regulatory agency databases was <br />performed by Environmental Data Resources Inc. (EDR), a data retrieval company, to <br />identify and locate properties in areas of concern that have been reported as sites <br />known or suspected to contain underground storage tanks, or to have been the scene <br />of hazardous materials spills. Additionally, sites permitted to manufacture, utilize, <br />generate, store, treat or dispose of hazardous materials and/or hazardous wastes are <br />identified and located. A list and description of databases investigated, in compliance <br />with ASTM E1527-13 and USEPA AAI, is included in EDR Report provided in <br />Appendix C. <br />3.3.1. SUBJECT PROPERTY DATABASE SEARCH <br />The property address 3009 Pock Lane, Stockton, California, was not listed on any <br />governmental databases within the EDR Report. <br />3.3.2. SITE VICINITY DATABASE SEARCH <br />Sites with recognized environmental conditions surrounding the subject property are <br />typically of concern to the subject property when they are located in an up-gradient <br />direction from the property with respect to the ground water flow direction. Typically, <br />groundwater would represent the migration medium for contaminants over significant <br />distances. Sites located in equi-gradient or down-gradient directions from the subject <br />property are less likely to impact the subject property. <br />AGI retained EDR to provide current regulatory database information compiled by a <br />variety of federal and state regulatory agencies. A copy of the complete database is <br />included in Appendix C. The following information was obtained: <br />Regulatory Agency <br />Database <br />Appropriate Minimum <br />Search Distance (AMSD) <br />Number of Sites within <br />AMSD <br />RCRA - Non Generators / No <br />Longer Regulated <br />0.25 3 <br />Leaking Underground Fuel Tank <br />Report (GEOTRACKER) <br />0.5 5 <br />Hazardous Substance Storage <br />Container Database <br />0.25 3 <br />"Cortese" Hazardous Waste & <br />Substances Sites List <br />0.5 5 <br />CERS HAZ WASTE 0.25 1 <br />EnviroStor Database 1 6 <br />Proposition 65 Records 1 1 <br />Hazardous Waste & Substance Site <br />List <br />0.5 4 <br />AG l's review of the referenced databases also considered the !potential or likelihood of <br />contamination from adjoining and nearby sites. To evaluate which of the adjoining and <br />nearby sites identified in the regulatory database report present an environmental risk <br />to the subject property, AGI considered the following: <br />The type of database on which the site is identified; <br />The topographic position of the identified site relative to the subject property; <br />The direction and distance of the identified site from the subject property;
