5.4 REFUSE <br />n� <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 <br />materials have not been disposed at the site. However, some items that are <br />currently defined as hazardous waste (paint, insecticides, etc.) may have been <br />included in household 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 <br />pot -holing and excavation, the area shall be cordoned off and the CIWMB and <br />EHD officers notified. The area shall be flagged and excluded from the work <br />zone until the drum can be better characterized. At no time shall workers attempt <br />to remove or handle any such item. If any suspicious odors or other materials <br />are observed by workers, the suspect debris and/or source shall be cordoned off <br />and CIWMB and EHD shall be contacted to conduct air monitoring or other <br />identification as appropriate. <br />5.5 DRILLING <br />Characterization of materials encountered during drilling will be performed by <br />inspection above original grade. Workers will not break the plane of an drilling <br />location with mouth or nostrils unless the safety of the excavation is first <br />monitored to verify that the environment meets OSHA requirements for oxygen <br />and combustible gas. Such monitoring will be with portable electronic test <br />equipment designed for that purpose with (Lantec GEM or equivalent). <br />Workers will not perform work that involves sources of combustion (such as <br />welding equipment) or any other work that generates temperatures that could <br />ignite methane, unless the safety of the area has been verified. <br />In the event that the oil pipeline which runs along the work area is ruptured when <br />drilling, the owner of the pipeline (Russell Guidry 310-816-2063) will be <br />immediately contacted. <br />Work Plan — Soil Gas Monitoring Well Installation San Joaquin County <br />Corral Hollow Sanitary Landfill Public Works Department <br />Page 6 of 7 Solid Waste Division <br />
