Spokane County commissioners are expected to award a $2.9 million contract Tuesday to a Port Angeles firm - the low bidder to cap the leaky old Colbert Landfill.
The landfill was closed in the mid-1980s after being named to the federal Superfund list of toxic cleanup sites.
It opened in 1968 at Yale and Elk-Chattaroy roads.
Taxpayers already have spent $11 million to clean nearby groundwater polluted by leaching chemicals from the 40-acre site.
The low bidder is Delhur Industries, a Port Angeles company that also has a small office in Hermiston, Ore.
The construction firm currently has a Hanford Nuclear Reservation contract and was used in the past to cap three other landfills in Spokane County.
“We do a lot of landfill work,” said company official Rick Hurworth.
Nine other firms bid from $3.2 million to $4.6 million to cover the landfill with a thick polyethylene cover and 2 feet of drainage sand and topsoil, said Bill Wedlake, county landfill closure manager.
The work must be completed by Nov. 30.
Commissioners on Tuesday also will hold a hearing on a proposed subdivision one-half mile east of Glenrose Road and 25th Avenue.
The subdivision would be called Morgan Murphy Estates and would involve slicing 208 acres into 41 lots and single-family homes. The developer is Steve Herling, general manager of KXLY-TV.
The commission also will hold a final hearing on whether to spend nearly $1 million on a new office building at Geiger Corrections Center.
