Should ENGEO. be contracted to observe the abandonment of any of the <br /> installed geotechnical equipment, we will contact the San Joaquin County Environmental Health <br /> Department to ensure the abandonment is done according to county regulations. <br /> At least 48 hours prior to our subsurface explorations, we will mark the site for an Underground <br /> Service Alert (USA) utilities check. Following the completion of project, the holes will be <br /> backfilled with neat cement grout in accordance with San Joaquin County regulations. <br /> If you have any questions on any portion of this work plan, please call and we will be glad to <br /> discuss them with you. <br /> Very truly yours, <br /> ENGEO INCORPORATED <br /> Richard G dol o /sef�J. otl <br /> Attachments: Figure 1 —Vicinity Map <br /> Figure 2—Sample Location Map <br />
