Re-excavation & resample steps: At this time we arerequesting a re-excavation <br /> and resample. The tank excavation, itself, has;lbeenjbackfilled. Our plan is to <br /> excavate an area approximately 10 feet wide y 18 fe 15 feet <br /> to 18 feet from the east side of the previoujtan excavation westward under he <br /> trac 'A—w-+t4 an obvious odor and/or discoloration will be stockpile on <br />' ite, on plastic and covered with same, Other excavated soil will be stock a' ed <br /> on site in a separate area. efu aminated <br /> s ' from, in and ar a excavated area. See drawing "C" for proposed exca- <br /> vation p acement of newly excavated soil . <br /> There will be approximately 97 to 11.7 cubic yards of soil excavated, depending <br /> on depth of excavation. See drawing "C" for plannedjlexcavation to 15 feet deep and <br /> 18 feet dee. We will be prepared to take as many samples .as the SJLHD deems neces- <br /> sary. —plan t take bottom samples from the excavated area as shown in drawing <br /> which also sh ws proposed sampling locations of' the previously removed stock- <br /> 'led soil and the site of the newly excavated soil stockpile area. We will test <br /> forL <br /> H (see i�hlighted area of the attached copy of Tank Plan Review Checklist- <br /> MinVer' cation Lab Analyses) . If water is encountered, we will be prepared <br /> ater samples and test as requested. <br /> Hopefully the sample result levels are low enough to allow remediation of <br /> the excavated soil on site. <br /> If the level of contaminates show too high] for remediation, the soil will <br /> be transported to a proper hazardous waste facility for disposal , namely Kettleman <br /> City, or possibly a Class 2 site, such as Forward, Inc. If the soil is removed <br /> from the site, it shall be transported under proper licensure. Any manifests <br /> l-;_produced during transfer shall have a copy provided to SJLHD within 30 days. <br /> i <br /> 6. Timing: Sampling could be scheduled within one week':following your review of <br /> this work plan. Advance inspection notice of at least 48 hours will be given ? <br /> to SJLHD for resampling inspection. The sample analysis should be ready for <br /> your review within two weeks after they have been taken. <br /> r <br /> i <br /> i <br /> jE <br /> I <br />
