Nevada Division of Environmental Protection - Bureau of Waste Management

Site Summary — The landfill property is located approximately 1.5 miles east of downtown Elko, Nevada and is owned by the City of Elko. It encompasses approximately 320 acres in the northeast quarter of Section 13, T. 34 N., R. 55 E and the northwest quarter of Section 18, T. 34 N, R. 56 E. The Elko area is situated in a northeast-trending structural valley bounded by the Adobe Range to the northwest, the Elko Hills to the east, and by an unnamed range of hills to the west.

Site Location Description— The original disposal area is constructed without a liner or leachate collection system however groundwater monitoring is conducted. The City of Elko recently requested a modification to the existing permit to include a lateral expansion that will include a liner with leachate collection. Upon reaching capacity, a final cover will be constructed, and the Permittee will be responsible for 30 years of post-closure care. The Class I MSW facility accepts waste predominantly from the local community and to a lesser extent the adjacent counties.

Final Cover — The Final Cover Configuration from bottom to top consists of 12 inch foundation layer, 18 inch screened native soil layer, and 6 inch erosion layer.

Perimeter Landfill Gas Monitoring — The City of Elko will conduct landfill gas probe Monitoring of the perimeter landfill. Monitoring the gas probes will be on a quarterly basis using appropriate monitoring equipment. Any buildings including the gate house will also be monitored for landfill gas on a quarterly basis.

Closure Sequencing — The Elko Landfill excavation and fill sequencing has been designed to maximize landfill capacity, schedule soil movement to minimize need for multiple handling, minimize landfilled area not final closed, and bring landfilled areas to final grade as soon as practical.

Post Closure — The Elko Landfill will implement various improvements during landfill operations and before final landfill closure. Those improvements include such items as: 1) landfill gas perimeter monitoring probe installations; 2) drainage detention basins; 3) perimeter drainage ditches; 4) access roads; and 5) site security.

Closure Construction — The closure construction items that are necessary to be constructed when final graded landfill areas are final covered with soil will include:

final cover soils (12 inch interim cover/foundation layer, 18 inch screened native soil layer, and 6 inch erosion layer)
vegetation (BLM native desert seed mix),
landfill surface drainage ditches,
landfill slope downdrain culverts,
drainage erosion protection,
top deck headwall diversion berms, and
construction quality assurance testing and certification
