HYDRD-SERRCH , INC . ID :303-279-7988 RUG 17 '95 13:07 No .013 P . 11 <br /> 0 <br /> approximately 2 feet above the top of the screen. Partial development of the filter pack will he <br /> initiated by surging prior to the placement of the well seal to allow for settling of the filter pack <br /> material. Approximately three feet of bentonite pellets will then be placed above the filter pack <br /> and hydrated. The remainder of the annulus will be filled with a cement/bentonite slurry. <br /> After a cement curing period of 24 hours, the well will be fully developed to produce clear, silt <br /> free water. Well development procedures to be utilized for this stage include mechanical surging <br /> and pumping. Development of the well will be considered satisfactory upon stabilization of the <br /> specific capacity (Q/s) based on measurements taken during the pumping phase of development. <br /> The surface completions of the recovery wells will consist of 2-foot by 2-foot below grade <br /> vaults. <br /> Short-term testing will be performed en the wells following cumpledull activities. T7)cse tests <br /> will aid in pump design for equipment installation and confirm the number of recovery wells <br /> required to provide containment for the site_ <br /> 6.4 Disposal of Drilling Wastes <br /> Drilling fluids and cuttings generated as part of the well installation procedures will be separated <br /> in a cyclone and/or portable mud pits equipped with a shale shaker. Drilling fluids will be <br /> transferred to tanks for temporary storage before treatment and disposal. Cuttings which will <br /> consist of clays, silt, sand, and gravel will be stored temporarily in roll-off bins. <br /> Disposal procedures for solid wastes will be selected on the basis of the results of laboratory <br /> analyses. If contaminants are detected above RWQCB or Federal standards, the waste will be <br /> transported by a licensed hauler under proper manifests to an appropriate facility. Appropriate <br /> documentation will be provided as required by the disposal facility. If all contaminants are <br /> detected below RWQCB and Federal standards, the solid material may be hauled to a San <br /> Joaquin County Class III landfill upon approval from the RWQCB, The liquid waste will be <br /> (uaw/vs) 41 Ct)a)np.rro <br />
