Work Plan for Phase II ESA September 11, 2014 Pap6 Properties, Inc. 10842 S Harlan Rd, French Camp, CA SCOPE OF WORK Appropriate investigative methodologies will be employed to assess the potential impacts to the subject property. 1.5 Drill Borings and Sample Soil and Groundwater • The proposed boring locations will be marked in white paint and Underground Service Alert and the property owner will be notified at least three (3) business days prior to drilling. • A drilling permit for the soil borings will obtained from the LOP. • Four (4) soil borings will be drilled at locations shown on Figure 2. The borings will be 2-inches in diameter and will be installed with direct-push (Geoprobe)technology by a drilling contractor with a current C-57 license. The drilling contractor will hand vacuum to five (5) feet for utilities prior to utilizing direct push. Up to two (2) additional borings may be installed, depending upon site conditions and the opinion of the geologist onsite. • The soil borings will be continuously sampled and field screened for the presence of petroleum hydrocarbon vapors using a photoionization device (PID). • Soil samples will be collected in each boring at intervals of five (5) feet,to a depth of up to 24 feet. The ends of each soil sample will be secured with plastic caps and the sampled will be labeled. • If groundwater is encountered, one grab groundwater sample will be collected from each boring using a low-flow pump. Water samples will be collected in new, clean VOAs provided by the laboratory. • Soil and water samples will be submitted to a State-certified laboratory for analytical testing. • Each boring will be backfilled with neat cement grout in accordance with LOP requirements and concrete patch will be applied to the top four(4) inches of the boring. • Investigative-derived wastes will be placed in DOT-approved steel drums, sealed, and labeled pending results of the analytical report. If the contents are determined to be hazardous,they will be transported to an appropriate TSDF by a licensed hazardous-waste disposal contractor. 1.6 Laboratory Analysis • Soil samples will be analyzed for Total Petroleum Hydrocarbons (TPH) as Diesel by EPA Method 80156, with Silica Gel Cleanup. • Water samples will be analyzed for Naphthalene and BTEX by EPA Method 8260B. QUALITY ASSURANCE/QUALITY CONTROL PLAN (QA/QC) 1.7 Field QA/QC • Sampling instruments will include a stainless steel hand auger, stainless steel Power Probe with probe sections lined with dedicated non-reactive plastic sleeves and sample vessels. • Sampling staff will wear clean, disposable nitrile gloves for each sample collected to reduce the risk of cross-contamination. ® PA004.02PH11(14) 2 1:\Pape\004 Kenworth\02.French Camp\2014\Phase II ESA Work Plan.docx �nLLUOrf.
