Fans blow methane from housing development built on landfill

EVERETT, Wash. (AP) — A Washington state residential development is using fans to blow away methane gas emitted from a decommissioned landfill on which the homes were built. The Everett Herald reports two fans at either end of the Riverfront Development in Everett suck the gas from the soil and blow out the vapor through a steel pipe. Plans for the six-phase development along the Snohomish River owned by Shelter Holdings include 1,250 multi-family units. The property is expected to generate small amounts of methane for years, but the production rate has slowed substantially and likely will continue to diminish over time.
