5 i GETTLER-RYAN INC. FIELD METHODS AND PROCEDURES Site Safety Plan Field work performed by Gettler-Ryan Inc (G-R) is conducted in accordance with G-R's Health and Safety Plan and the Site Safety Plan G-R personnel and subcontractors who perform work at the site are briefed on the contents of these plans prior to initiating site work The G-R geologist or engineer at the site when the work is performed acts as the Site Safety Officer G-R utilizes a photoionization detector (FID) to monitor ambient conditions as part of the Health and Safety Plan Well Abandonment Prior to well abandonment, the total depth of the well and the depth-to-water in the well casing are measured and recorded Groundwater monitoring wells are abandoned by filling the well casing with neat cement using a tremme pipe and pump The trenue is removed and the cement in the well casing is pressurized to approximately 10 pounds per square inch (psi) for approximately 2 minutes The well box is removed and the upper S feet of well casing is drilled out The boring is then backfilled with neat cement or native material, depending on local regulations iWell Destruction Prior to well destruction, the total depth of the well and the depth-to-water in the well casing are measured and recorded Groundwater monitoring wells are destroyed by drilling the well boring out to remove the casing, sandpack, and seal material The boring is advanced at least one foot past the installed depth of the well to insure that all the casing and seal material are removed Upon completion of drilling, the boring is backfilled to ground surface with neat cement placed using a trenue pipe and pump Storine and Samolinu of Drill Cuttings Drill cuttings are stockpiled on and covered with plastic sheeting or stored in drums depending on site conditions and regulatory requirements Stockpile samples are collected and analyzed for disposal classification on the basis of one composite sample per 100 cubic yards of soil Stockpile samples are composed of four discrete soil samples, each collected from an arbitrary location on the stockpile The four discrete samples are then composited in the laboratory prior to analysis Each discrete stockpile sample is collected by removing the upper 3 to G inches of soil, and them driving the stainless steel or brass sample tube into the stockpiled material with a hand, mallet, or drive sampler The sample tubes are then covered on both ends with teflon sheeting or aluminum foil, capped, labeled, and placed in a cooler with blue ice for preservation A chain-of-custody form is initiated in the field and accompanies the selected soil samples to the analytical laboratory Stockpiled soils are covered with plastic sheeting after completion of sampling A-1
