Landfill Case History
Campbell Mountain Landfill Case History
and Shingle landfill case history.
In early November 1999, a 250,000
cu. yd. cell of the Delta Shake and Shingle Landfill erupted in
Flames. The initial extinguishment efforts by the Landfill owner
accelerated combustion of the construction waste. Within weeks,
smoke from the fire cast a thick haze over the Vancouver skyline,
streams in the area were threatened by leachate from the fire
fight and workers on adjacent properties were being affected by
smoke and odors. On November 27th, the mayor of Delta declared
a State of Local Emergency and the British Columbia Fire Commissioner
ordered the Delta Fire Department to take control and extinguish
Complicating the firefight at the
landfill was the presence of a high pressure natural gas main
that provides heating fuel for nearly on half million customers
in Vancouver, as well as a large volume sewer force main, a water
supply main, a high voltage transmission line and a railway line.
All of these utilities were located immediately adjacent to the
landfill in unstable peats, and were potentially threatened
if a slope failure or excessive settlement were to occur during
The extinguishment strategy involved
closing up the 200 x 200 yd. burn Zone, rapid construction of
PVC lined cool down areas on expropriated property, excavation
and wetting down of the burning material, and ultimately replacement
of the extinguished material back in the landfill.
Geotechnical design and monitoring
of the lay down areas on top of and adjacent to the landfill were
key aspects of the project as the gas pipeline company had zero
tolerance for stress induced displacements.
The fire was fully extinguished
over a period of two months at a cost of exceeding $2.4 million.
The extinguished material was placed back in the landfill in a
fire-proof manner and properties expropriated during the fire
fight were restored to their owners at a cost of $1.6 million.
