20 September 2012 <br />AGE Project No. 12-2193 <br />Page 2 of 3 <br />• On-site chemicals and potential hazardous substances as well as physical hazards. <br />• Risk analysis for existing site conditions, and description of personal protective <br />equipment to be used by personnel. <br />• Site control measures, including work zones and security measures, and entry <br />procedures for confined spaces, if required. <br />• Exposure monitoring plan with monitoring methods, emergency response plan <br />addressing hazardous material/waste releases, and medical surveillance <br />requirements. <br />All field personnel will be trained in hazardous materials communication and will have <br />completed a 40 -hour Health and Safety Course as specified in OSHA Hazardous Waste <br />Operations and Emergency Response Standard [29 CFR 1910.120(e)], and 8-hourannual <br />refresher courses as necessary. <br />AGE proposes to advance shallow soil borings every 20 liner feet adjacent to the line run <br />for the collection of soil samples. All borings will be advanced using a 2 -inch diameter <br />hand -auger to clear each location for utilities and then with a direct push sampling tool and <br />1.25 -inch soil sampling tools. Borings will be advanced outside of the line trench at an <br />angle of approximately 30 degrees from vertical to obtain samples beneath the line. <br />Proposed boring location are illustrated on Figure 1. The locations will be evaluated with <br />EHD staff prior to soil sample collection. <br />Samples will be collected from each location at a depths of approximately four to six <br />vertical feet (eight to ten angled feet). Each sample will be collected using a soil sampler <br />and stainless steel or acetate sleeves. Upon sample retrieval, the ends of a selected <br />sleeve will be covered with Teflon sheets, capped and sealed with tape. Appropriately <br />sealed and labeled samples will be placed in a chilled container under ice and transported <br />under chain -of -custody procedure to Cal Tech Environmental Laboratories, a California <br />Department of Public Health certified laboratory located in Paramount, California. The <br />collected soil samples will be analyzed for: <br />• Total Petroleum Hydrocarbons quantified as diesel (TPH-d) in accordance with EPA <br />Method 8015 Modified. <br />Benzene, toluene, ethyl benzene and xylenes (BTEX) and fuel oxygenating <br />compounds in accordance with EPA Method 8260B. <br />Advanced GeoEnvironmental, Inc. <br />
