Washington Releases Annual Environmental Monitoring Report

In the spring of 2017, the Office of Radiation Protection, Environmental Public Health Division, Washington State Department of Health released US Ecology Washington’s Annual Environmental Monitoring Report for Calendar Year 2015.

Each year, US Ecology Washington submits an annual report, which is required by state law and the Washington State Department of Health’s license conditions as per Washington Administrative Code (WAC) 246-250-600.  WAC 246-250-340 also requires environmental monitoring.

US Ecology Washington receives and disposes low-level radioactive waste at the Hanford Site near Richland, Washington.

The report is now available on the agency’s website at www.doh.wa.gov.  For additional information, please contact Kate Lynch at (360) 236-3259 or at kate.lynch@doh.wa.gov.

Special Inspection Conducted at Columbia Nuclear Generating Station

On December 12, 2016, the U.S. Nuclear Regulatory Commission (NRC) announced that the agency has begun a special inspection at the Columbia Generating Station to review circumstances surrounding the shipment of some low-level waste to a disposal facility.  The plant, operated by Energy Northwest, is located near Richland, Washington.


On November 9, 2016, workers at the plant shipped a single package of low-level nuclear waste to the
 U.S. Ecology disposal facility about 10 miles away.  When the package containing contaminated filters arrived, workers at the disposal facility noted a discrepancy between the radiation levels specified in the shipping manifest and dose rates they measured on the shipping container.  US Ecology personnel measured radiation levels more than seven times higher than documented in the shipping manifest.  The package was rejected and taken back to the plant where it is currently being stored.

The following day, the Washington State Department of Health (WDOH) notified Columbia Generating Station officials that their disposal permit privileges to US Ecology were being suspended until a written plan containing corrective actions was approved and an on-site inspection conducted by state officials is completed.

Special Inspection

“The purpose of the NRC’s special inspection is to better understand the circumstances surrounding this event, which revealed weaknesses in the licensee’s process for packaging and preparing radioactive waste shipments,” NRC Region IV Administrator Kriss Kennedy said.  “While there was no undue risk to the public, had a transportation accident occurred, there was a potential that members of the public could have been exposed to radiation levels in excess of NRC regulatory limits.”

The three-member NRC team spent about a week on site evaluating the licensee’s cause analysis and the adequacy of corrective actions.  An inspection report documenting the team’s findings will be publicly available within 45 days of the end of the inspection.
