Based on an inspection of <br /> the facilities on February 20, 2014 and information provided as discussed <br /> above, ERM has formulated a soil sampling plan as outlined below. The <br /> objective of the sampling is to determine whether impacts to soil have <br /> occurred, and to provide an order of magnitude assessment of the <br /> impacts. <br /> Health and Safety Plan <br /> A health and safety plan (HASP) will be formulated that will address all <br /> hazards and govern field activities related to the soil sampling. The <br /> HASP will govern activities of ERM, subcontractor and any other <br /> personnel present during field activities. The HASP will address safety <br /> issues related to work in the vicinity of a gas compressors. <br /> Soil Sampling <br /> Samples will be collected in areas either observed to be impacted or <br /> considered to have potential to be impacted by site operations. <br /> North Compressor Station- Units K3-K6 (Figure 2) <br /> Potential sources of impacts to soil are as follows: <br /> • Leaks from compressor containment areas (4) <br /> Soil samples will be collected from eight locations; two locations <br /> proximal to each of the four containment areas as illustrated on <br /> Figure 2. Samples will be collected from these borings at depths of <br /> 0-0.5 feet, 4.5-5 feet, and 9.5-10 feet below ground surface (bgs). If <br /> impacts are observed at the bottom of the boring and groundwater is <br /> not observed, the boring will be advanced until staining is not <br /> observed or groundwater is encountered. Samples will be collected <br /> every 5 feet in depth. <br /> • Leaks, spray from air exchangers (4) <br /> Soil samples will be collected from four locations; one location at <br /> each of the air exchange units as illustrated on Figure 2. Samples will <br />
