The landfill is situated in a location accessable by rail or truck. (Truck/rail routes). From Interstate 8 the preferred route is through the Reservation south for approximately seven miles with one highway crossing at Highway 94. Several upgrades to the roads and crossings within the Reservation are required by the Environmental Impact Statement prior to operations commencing.

Liner Design

The liner system for the Campo Landfill is very close to that for a Class 2, hazardous waste design. Yet, tribal and federal standards will only permit the disposal of Class 3, municipal solid waste.

The landfill will include a double liner system comprised of a composite liner and a additional, single synthetic liner. The liner system will incorporate a primary leachate collection and removal system (LCRS) above the secondary liner, and a secondary LCRS serving as a leak detection system (LDS) under the primary liner. Beneath both is a vadose (definition – water of solutions in the earth’s crust above the permanent ground water level) zone monitoring system. The LCRS and LDS are designed to collect all the leachate in the landfill and safely divert it to removal points. The base of the landfill will be graded to ensure that there will be a minimum 5-foot separation between the highest ground water elevations and the base of the landfill. Protection of ground water resources and safe containment of the waste and its byproducts is the primary function of the double liner system.

Landfill Gas Control

The Campo EPA established a requirement for gas controls in excess of those required under federal or State of California standards. As the waste is deposited, gas collection piping will be laid at appropriate intervals to draw off methane and other trace gases to flares. The flares will operate with a destruction efficiency established by federal standards.
