~ Inspection Report Page 2 of 2 13 December 2018 <br /> . P P 9 <br /> Harvest-Lathrop Composting Facility <br /> San Joaquin County <br /> over compacted native soil to construct an all-weather low permeability compost working surface. <br /> Photo 2 shows the existing unlined wastewater pond. The wastewater pond had very little storage <br /> capacity due to accumulated solids. Photos 3 through 8, 10, and 11 shows various areas where <br /> ponding and rutting had occurred. Photo 4 shows a road that was recently constructed using <br /> compacted aggregate base. The road showed signs of rutting and ponding. Photo 9 shows the area <br /> where incoming green waste is stockpiled prior to placement in windrows for composting. <br /> 3. DISCUSSION: <br /> The inspection showed that the facility has numerous areas where ponding has occurred on the <br /> working area and the working surface is currently not capable of handling equipment traffic without <br /> damage due to rutting under wet conditions. Furthermore, it is questionable whether the Discharger's <br /> existing unlined wastewater pond has enough capacity to contain wastewater runoff during the 2018- <br /> 2019 wet season. Also, there is concern weather the Discharger's proposed improvements to the <br /> working surface by adding 12 inches of compacted aggregate base will provide an all-weather working <br /> surface without damage due to vehicle traffic. This concern is supported by the observation made in <br /> Photo 4 where ponding and rutting had occurred on a recently constructed road using aggregate base <br /> material. Finally, there was little evidence that the Discharger had begun improvements to the facility in <br /> accordance with those specified to be completed by 1 November 2018. <br /> 4. CONCLUSIONS/RECOMMENDATIONS: <br /> The inspection found that the Discharger's facility is currently in very poor condition at the onset of the <br /> 2018-2019 wet season and that the Discharger has not complied with the requirements of the NOA to <br /> make improvements such as construction/reconstruction of Wastewater Detention Ponds 1 and 2, <br /> associated pan lysimeters, and enough of the working pad area, access roads, and drainage ditches <br /> that feed the detention ponds to allow the Discharger to operate through the 2018-2019 wet season, <br /> including piezometers for gr ' aration monitoring. <br /> 'y, <br /> KU <br /> 01 <br /> Vin Jain, #M30 g <br /> Water Resources Contro + <br /> Title 27 Permitting and Min <br /> Attachments: <br /> Attachment 1.
