Oxford Energy had a major stake in a major local scrap tire pile operation. It was the largest single collection of waste tires on the west coast, when it mostly burnt down in 1997. Filbin had begun trucking used tires into Ed's Tire Disposal even before construction of I-5, the road being built between 1956 and 1979, depending on location. Oxford Energy had begun dumping near Westley in various piles since the 1950s. Oxford Energy officials heard about it causing an eyesore and environmental blight in 1984 and approached both Filbin and the county, proposing the tire-to-energy project, but it was turned down on environmental grounds. It was under a 24 hour security guarding regime in 1987. About 10,000-20,000 tires were being dumped there each day during 1987. In 1997, when dump had grown to about 6,000,000 tires during 1997 the state stepped in under a special local legislative mandate to dispose of them. Shortly after the local photographer, Mr Burtynsky, had photographed Oxford Pile #8 during 1997, a lightning strike in the facility started a fire in the old tire pile that took weeks to extinguish.
