Work Plan <br /> November 16,2006 <br /> SCOPE OF WORK <br /> The proposed scope of services will include the following: <br /> Preliminary Activities <br /> Health and Safety Plan <br /> Since the proposed work may involve hazardous substances and potentially dangerous conditions, it will <br /> be necessary to develop a Health and Safety Plan that is specific to this site. The Occupational Safety and <br /> Health Administration (OSHA), under Hazardous Waste Operations & Emergency Response 29 CFR <br /> 1910.120, requires the development of this plan. The site Health and Safety Plan is designed to reduce <br /> the risk of physical or chemical exposures that may affect workers in the proposed work area. The site <br /> Health and Safety Plan includes information about chemicals expected on the site, health and safety <br /> procedures for working on-site and emergency response procedures. <br /> Utility Markout <br /> California law requires that at least 72 hour notice is required prior to the initiation of any subsurface <br /> work (drilling, backhoe operation, etc.), that Underground Service Alert be contacted and a utility <br /> inspection be performed at the subject property. This inspection consists of the marking of underground <br /> utility locations by participating utilities. <br /> Subsurface Investigation <br /> Four soil borings will be completed on the property to ten feet below grade level (BGL) with a Geoprobe <br /> drilling rig. The borings will be completed at the former hazardous waste storage area to the south of <br /> Building 5, at the storm water retention pond near Building 6, at the glue rinse area/interceptor at <br /> Building 4, and along the rail road spur. <br /> Continuous soil samples will be collected from land surface to the terminal depths of the borings. The <br /> samples will be field screened with a photo-ionization detector (PID) to determine if volatile organic <br /> vapors are present. One soil sample per boring (total of four samples) will be selected for chemical <br /> analysis based upon the PID measurements and field observations. The soil samples will be analyzed for <br /> volatile organic compounds (VOCs) by EPA Method 8260 and for semi-volatile organic compounds <br /> (SVOCs) by EPA Method 8270. Additionally, the samples from the retention pond and rail road spur <br /> will be analyzed for RCRA metals. <br /> Following the soil sampling activities, ground water samples will be collected at the rear of Building 5 <br /> and at the glue rinse area/interceptor at Building 4. To collect the ground water samples, the borings at <br /> these locations will be deepened to 30 feet BGL. Temporary wells constructed of one-inch inside <br /> diameter (ID) well screen and riser pipe will be constructed in the two borings, or the ground water <br /> samples will be collected through stainless steel sampling points. The ground water samples will be <br /> retrieved with a low-flow peristaltic pump or with disposable bailers, and will be analyzed for VOCs and <br /> SVOCs by EPA Methods 8260 and 8270,respectively. <br /> 2 <br />
