21 July 2015 AGE Project No. 14-3154 Page 7 of 15 • Permitting and pre-field work activities; • Advancement of soil borings for collection of soil/groundwater samples; • Collection of groundwater samples from three or more monitoring wells; • Groundwater sample analysis; • Infiltrated groundwater sample collection and analysis; • Soil trenching to quantify the potential for disposal site conditions; • Determine the vertical/horizontal extent of the waste; • Soil sample analysis; and • Report preparation. Each of these tasks is discussed below in detail. PERMITTING AND PRE-FIELD WORK PREPARATIONS Applicable soil boring permits will be obtained from SJCEHD. An update to the health and safety plan presently on-file will be prepared in accordance with Occupational Safety and Health Guidance Manual for Hazardous Waste Site Activities (National Institute for Occupational Safety and Health Administration, U.S. Coast Guard and U.S. Environmental Protection Agency, 1985). Prior to mobilization, the area of excavation will be clearly marked and a utility clearance obtained through Underground Service Alert. The SJCEHD will be contacted at least 48 hours prior to conducting any field work. SOIL BORING AND SAMPLING AGE proposes to advance a total of five soil probe borings utilizing a direct push drilling rig and six boring utilizing hand auger tooling to evaluate the presence and define the type or extent of petroleum hydrocarbon, metals-impacted or production waste chemicals. Soil and groundwater samples will be selectively collected between 5 feet and approximately 25 feet bsg. The anticipated depth to groundwater from soil borings is approximately twenty feet bsg. Shallow soil sampling will be conducted at approximately one-foot bsg for historical surface water ponds. Proposed soil boring locations are depicted in Figure 2. A description of proposed soil boring locations is provided below: Advanced GcoEnvironmental,Inc.
