Lodi City Landfill November 16,2011 North of Awani Drive,Lodi,California Project No. 104690061 • Notify applicable regulatory agency and other personnel of the planned site investigation schedules a minimum of one week prior to conducting the fieldwork. • Obtain an approved well and boring permit from the San Joaquin County Environmental Health Department to drill and construct the LFG monitoring wells. • Stake the proposed LFG monitoring well and exploratory trench locations in the field with survey flagging and wooden stakes or spray paint based on this work plan and information obtained during the October 2011 site reconnaissance. • Notify Underground Service Alert (USA), a public utility locator, of the proposed LFG monitoring well boring and exploratory trench locations a minimum of 48 hours before field activities start so that they can contact representatives of utility companies in the area. • Arrange for and oversee a geophysical survey to evaluate potential subsurface utility con- flicts at each proposed LFG well and exploratory trench location. • Retain a qualified, experienced C-57-licensed drilling contractor to provide equipment and a 40-hour Occupational Safety and Health Administration (OSHA) trained operator to drill borings and construct LFG wells. The planned subcontractor will provide appropriate cur- rent certificates, experience, and training, relevant to the planned site investigation. They will drill approximately 10 borings and construct LFG wells in each boring to depths that correspond to the depth of wastes in that area or to depths shallower than groundwater. The LFG monitoring wells will be constructed in general accordance with applicable portions of Title 27 California Code of Regulations(CCR) for LFG monitoring programs. • Retain a licensed, qualified, and experienced backhoe contractor to provide equipment and a 40-hour Hazardous Waste Operations and Emergency Response (HAZWOPER) trained op- erator to excavate/backfill exploratory trenches and a 40-hour HAZWOPER trained technician to provide dust control. The planned subcontractor will provide appropriate cur- rent certificates,experience, and training,relevant to the planned site investigation. • Provide a California registered professional geologist, engineering geologist or engineer; or personnel experienced in such investigations and working directly under said professional, to observe and document subsurface drilling and exploratory excavations and other field activi- ties. The field personnel will observe exploratory trench excavations, spoils, and sidewalls, collect samples,and document observations and sample locations with photographs and on in- dividual trench logs. Similarly,field personnel will collect samples and document observations and sample locations with photographs and on individual boring/well construction logs. They will indicate the depths/locations, types, and estimated percentages of wastes based on field observations and graphically present this information on individual trench and boring logs. 104690061 R Eng.dm 18 t#hyo 4/ uur e
