Weber Street <br /> Stockton, California 952.02 <br /> Re: Work Plan Addendum <br /> PG & E Trench Project <br /> Byron Road, Tracy, California <br /> Dear Mr, Infurna: <br /> ECM Group (ECM) has prepared this work plan addendum to provide additional <br /> information for the upcoming soil and ground water sampling at the subject site. <br /> The following items address comments on the work plan submitted for this project. <br /> 1 . A vicinity map and site plan are attached. The site plan was reduced from <br /> blueprints of the planned trenching work. Boring locations are spaced <br /> approximately 100 ft apart along the trench alignment.. <br /> 2. ECM has contacted PG&E staff to obtain a copy of the encroachment permit <br /> for the trenching project. The encroachment permit will be forwarded to <br /> your office directly by PG&E or City of Tracy staff. <br /> 3. Soil cuttings generated during the drilling work will be stockpiled on and <br /> covered with visqueen. The soil will be stored on site pending the analytic <br /> results. The soil cuttings will be added to trench spoils for reuse as backfill, <br /> unless the analytic result's indicate that an alternative disposal method is <br /> required. <br /> Thank you for your prompt attention to this permit. Please call if you have any <br /> questions. <br /> Sincere 'l <br /> EC ro <br /> L~hYe J.
