PART 1 GENERAL <br /> 1.01 SUMMARY <br /> Section covers the installation of four (4) dual landfill gas (LFG) extraction <br /> wells at Harney Lane Landfill (HLSL), located at 14750 E. Harney Lane, <br /> Lodi, California (Figure 1). <br /> The Contractor shall do all work as shown on the construction drawings and <br /> as specified here-in. <br /> 1.02 SITE CONDITIONS <br /> A. General <br /> 1. The new LFG wells will be installed in refuse; therefore, work of this <br /> contract includes excavation of refuse or contact with refuse. <br /> 2. The drilling locations of the new LFG Extraction wells are near existing <br /> LFG extraction wells and laterals. <br /> 3. A high pressure condensate sump air line and a condensate discharge <br /> line are along the header. <br /> 4. During drilling, lateral trench excavation, or header connection the <br /> Contractor shall protect existing LFG piping. The Contractor shall be <br /> liable for damage to existing LFG system piping. <br /> B. Refuse <br /> HLSL 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. Unidentified drums may be <br /> present in the refuse at HLSL. If drums are removed during drilling, the <br /> area will be cordoned off and San Joaquin County Environmental Health <br /> (EHD) officers notified. The area shall be flagged and excluded from the <br /> work zone until the drum can be characterized. <br /> C. Landfill Gas (LFG) <br /> When buried in a landfill, refuse and other organic material produces LFG, <br /> which is approximately 50 percent methane by volume and may contain <br /> other contaminants. The lower explosive limit of methane is 5 percent by <br /> volume. The Contractor shall ensure the work area meets all safety <br /> requirements. <br /> Construction Specifications San Joaquin County <br /> Dual LFG Extraction Wells Public Works Department <br /> Harney Lane Sanitary Landfill Page 1 of 13 Solid Waste Division <br /> Revised 11-18-09 <br />
