FORWARD LANDFILL <br /> CANNERY MUD OPERATION PLAN <br /> Cannery muds are derived from the removal of dirt from produce in preparation for <br /> canning. The produce comes into the cannery with dirt from the field or orchards where <br /> it is grown. The dirt must be removed prior to canning by washing with water. Mud is <br /> the portion of the resulting material that settles out of the rinsate water and is collected <br /> and transported in roll-off containers rather than the tanker trucks used for the rinsate <br /> water. The solids or mud contain approximately 40 to 50 percent solids when delivered <br /> to the site. <br /> The cannery mud is unloaded from the roll-off containers on an approximately 2.5 to 3 <br /> foot thick clay-lined pad that has been constructed above the Class II WMUs FU-04 and <br /> FU-05. The approximately 5 acre mud drying pad is roughly divided into three sections <br /> which are worked systematically to allow sufficient area for rapid drying. The pad is <br /> bermed and is constructed with clays from the same on-site source as used to obtain clay <br /> liner material for the base liner of the Class II WMUs. The clay-lined pad prevents <br /> percolation of water into the underlying waste mass. <br /> Forward has two equipment operators assigned to the cannery mud drying operation. <br /> Cannery mud is off-loaded from the roll-off containers and immediately spread to a <br /> thickness of approximately 2 to 3-inches with a tractor and box scraper, making sure <br /> there is no moisture accumulation on the clay pad. The mud is initially allowed to air dry <br /> for approximately 4 to 5 hours. A disc is then used to turn the muds and allow further air <br /> drying. The following day, the muds are checked to assess if the material is dry. If the <br /> muds are not sufficiently dry, they are again turned with a disc and allowed to air dry. <br /> The cannery mud typically dries within 24 to 48 hours. Once the cannery mud is suitably <br /> dry, it is pushed into a stockpile using a bulldozer, loaded into a dump truck with a front- <br /> wheel loader, and transported to the active face. <br /> This operation has not been a source of flies or odors due to the rapid drying of muds and <br /> the minimal amount of organic material that is in the cannery mud. Operators have been <br /> trained to differentiate between mud loads and residual material loads to prevent the <br /> mingling of residual material with mud loads. A minor percentage of residual materials <br /> (whole fruits and vines, pomace, culls, leaves, peels, and seeds) are occasionally found in <br /> the cannery mud. These residual materials are loaded onto a dump truck and moved to <br /> Forward Resource Recovery Facility for composting. <br />
