Musco Family Olive Company - 2 - 2 December 2016 <br /> Class II Site Inspection Report <br /> November 2016 Site Inspection <br /> On 8 November 2016 staff conducted a second site inspection connected with the <br /> decommissioning of Pond A. Photograph 10 shows sections of the liner had not been <br /> completely removed. As shown in Photographs 11 through 16, all residual liquids, solids, and a <br /> majority of the primary liner had been removed. The LCRS sand was exposed and Musco had <br /> performed sample collection of the sand for chemical analysis. Musco's contractor was <br /> performing the last removal of soil and other residuals that would also be disposed of at <br /> Altamont Landfill. Staff inspected the LCRS sand for possible staining or standing liquid. As <br /> shown in Photograph 12, the sand appeared to be of uniform size and was relatively clean <br /> looking. Musco is waiting for laboratory analysis of the sand prior to removing it from the pond. <br /> Removal of the LCRS sand from the pond is a requirement of the approved clean closure plan <br /> and not dependent on the laboratory results. Once the LCRS sand is removed, the secondary <br /> clay liner will be exposed and sampled in accordance with the approved Clean Closure Work <br /> Plan, Revision 3.0. <br /> Next Steps <br /> Musco has been communicating with staff when certain project phases have been completed <br /> and the next phase will start. Currently, Musco intends to perform the removal of the LCRS <br /> sand between the end of November and early December, weather dependent. Following <br /> removal of the LCRS sand, the secondary clay liner and underlying native material will be <br /> sampled in accordance with the approved Clean Closure Work Plan, Revision 3.0. Staff intends <br /> to conduct a third inspection when the secondary clay liner is exposed and sampling is being <br /> conducted. <br /> Please call me at 916-464-4737 or email me at tdelfrate(a)-waterboards.ca.gov if you have <br /> questions. <br /> TODD A.
