' Draft Environmental Impact Report p p Page III-25 Forward Inc. Landfill Expansion t appropriate facility, and the rejected load would be recorded on the load checking occurrence sheet. If the vehicle has already left the site when unacceptable or hazardous wastes are found, r . i the containerized materials would be moved to a hazardous waste storage locker for temporary storage and disposal within 90 days. The container would be labeled with the generator's name r.. ry. and the date and time of the delivery. The generator would be informed that they must remove the materials and dispose of the waste at an appropriate disposal facility. If the generator refuses to handle the removal of the unacceptable or hazardous waste,Forward would arrange for the proper disposal of the materials. G, If hazardous waste is discovered that is not containerized, such that reloading the waste onto the vehicle is not possible, the area would be marked off, and all employees would be instructed to evacuate the area. Forward would notify the Manteca-Lathrop Fire Department, San Joaquin County of Emergency Services, Governor's Office of Emergency Services, and the SanTJoaq uin r. County_I'ublic_Health Sevice`s..(Enwironmental'Healt Division). The�appropriate-agency -- r would handle the containment and clean-up of the hazardous material. If the non- containerized waste is not hazardous,but is otherwise unacceptable, Forward would remove the waste from the processing area, contain it,and mark the waste as unacceptable. The generator would be informed that he must remove the waste from the site and dispose if it at a site licensed to accept the material. Incidents of unacceptable non-containerized waste would t be recorded in a load checking occurrence sheet. Once approved by Forward for acceptance, the wastes would be placed directly into the mixing t basin(described below),and solidified as soon as practicable. Forward may also store liquids outside of the mixing basin provided they are in water-tight,structurally sound containers(e.g., drums)and on paved portions of the solidification area. Typically only one type of liquid would ` TE, be added to the mixing basins at a time, solidified, and then removed for disposal. However, in some cases, such as with drums, different types of liquids may be solidified in the mixing basins at one time. In these cases, the Generator Waste Profile Sheet would be reviewed to ensure that the liquids are compatible, prior to solidification. The solidification agent(typically ash,auto shredder ..w waste,or green waste)may be added either before or after the liquid has been deposited into the mixing basin. If the solidification agent(e.g., ash)has the potential to create airborne dust, then the F. liquids would be placed in the basin after the solidification agent. Solidification agents may be stored in the solidification area,but typically would be placed there just prior to use. Dust and odors are not anticipated to be significant based on the review of similar practices at other landfills;however,any dust or odor conditions that may arise from the solidification agents or the mixing process would be identified and handled in accordance with current practices at the landfill. The basin would be filled with an appropriate amount of liquid and solidification agent to ensure complete mixing and to prevent overtopping during mixing and/or a storm event. The solidification agent would be mixed/combined with the liquid waste until there is thorough F blending of the liquid waste and solidification agent and no free liquids are observed. Typical mixing equipment consists of an excavator or backhoe bucket with a smooth blade or straight &I rubber cutting edge. Splashing and spillage would be minimized by limiting the amount of liquid and solidification agent in the mixing basin and by careful mixing by the equipment operator. The ► total mixing time is dependent upon the initial solids content of the liquids waste to be solidified and the solidification agent used. Typically, mixing occurs in about ten minutes. Minimal bulking occurs during the solidification process. Generally,the liquid waste fills the voids in the solidification agent.
