Aurora Street, <br /> Property Location and E. Jackson Street in Stockton, California. Figure 1 illustrates <br /> the Site Location Map. <br /> General Setting The general setting is mixed commercial/residential. <br /> Property Type Auto Repair/Service <br /> 2.2 OBJECTIVE <br /> The subject site was used for auto repair services since the 1960's. Based on past use of hazardous <br /> materials at the property, there is the risk of a release of these materials that could potentially affect the <br /> subsurface. The objective of this limited subsurface investigation is to determine the soil conditions at the <br /> subject property. <br /> ENCON's investigation included contacting Underground Service Alert (USA) prior to drilling, conducting <br /> a utility clearance survey, and advance eight soil borings at suspected past use of hazardous materials to <br /> a maximum depth of approximately 20 feet below ground surface (bgs) in the areas of potential <br /> environmental concern. <br /> 2.3 SCOPE OF WORK <br /> To accomplish the aforementioned objective, ENCON performed the following tasks: <br /> Pre-Field Activities: <br /> ENCON performed a Site Visit to verify existing conditions and pre-mark boring locations and notified <br /> Underground Service Alert (USA) on November 25th, 2013 of the intent to excavate or drill so that <br /> subsurface utilities would be marked to avoid potential damage. ENCON contracted Cruz Brothers <br /> Locators (CBL) to conduct a geophysical survey to clear utility lines and search for any subsurface <br /> anomalies on November 25th, 2013. <br /> A Site-specific Health and Safety Plan (Level D Health & Safety according to OSHA CFR 1910.120), <br /> Boring Plan, and Work-Schedule were prepared and ENCON notified the Property Owner of the proposed <br /> work schedule. A drilling permit application was submitted to the San Joaquin County Environmental <br /> Health Department. <br /> Encon Solutions, Inc. <br /> -5- <br />
