Refuse <br />Refuse will not be excavated in this investigation. The following is provided for <br />completeness. <br />The landfill contains household refuse, demolition debris, tree trimmings, and <br />miscellaneous refuse. To the best knowledge of the County, hazardous materials <br />have not been disposed at the site. However, some items that are currently defined as <br />hazardous waste (paint, insecticides, etc.) may have been included in household <br />waste disposed at the site. <br />Potential hazards associated with the direct contact with refuse include: <br />1.Biological infection <br />2.Household hazardous waste <br />Unidentified drums may be present in the refuse. If drums are uncovered during pot- <br />holing and excavation, the area shall be cordoned off and the CIWMB and EHD <br />officers notified. The area shall be flagged and excluded from the work zone until the <br />drum can be better characterized. At no time shall workers attempt to remove or <br />handle any such item. If any suspicious odors or other materials are observed by <br />workers, the suspect debris and/or source shall be cordoned off and CIWMB and EHD <br />shall be contacted to conduct air monitoring or other identification as appropriate. <br />5.3 Drilling <br />Workers will not break the plane of an excavation or borehole with mouth or nostrils <br />unless the safety of the excavation is first monitored to verify that the environment <br />meets OSHA requirements for oxygen and combustible gas. Such monitoring will be <br />with portable electronic test equipment designed for that purpose with (Lantec GEM or <br />equivalent). <br />Workers will not perform work that involves sources of combustion (such as welding <br />equipment), or any other work that generates temperatures that could ignite methane, <br />unless the safety of the area has been verified. <br />In the event that the oil pipeline which runs along the work area is damaged when <br />drilling, the owner of the pipeline (Russell Guidry 310-816-2063) will be immediately <br />contacted. <br />5.4 Equipment <br />The driller will provide all necessary drilling equipment. It is anticipated that a truck <br />mounted drill rig will be used. <br />Work Plan —Groundwater Monitoring Well Installation 7 San Joaquin County <br />Corral Hollow Sanitary Landfill Public Works/Solid Waste <br />
