The dust has settled from the March blast at the Williams Northwest Pipeline natural gas facility in Plymouth, WA, that injured five people, and now the final costs will be $69 million.

A pressure vessel ruptured at the facility, throwing a piece of shrapnel into a liquid natural-gas storage tank at the processing plant in Plymouth, just across the Columbia River from Umatilla, Oregon.

The blast forced hundreds of people to evacuate within a 2-mile radius of the plant and went across the Columbia River to Umatilla, OR.

At the time, the Benton County Sheriff’s Department said they got help from the wind which helped blow the gas away.

Federal safety investigators are still looking into the cause of the accident.

A spokeswoman for the Salt Lake City-based company, Michele Swaner, said full operations resumed in November and repairs should wrap up by April.

Two storage tanks hold up to 14 million gallons of liquid natural gas to meet peak winter demands on the pipeline that carries gas through Washington, Oregon, Idaho, Wyoming, Utah and Colorado.
