We conduct reviews about every five years when some contamination remains on-site after cleanup.
The Metro Lake Union site is on the north shore of Lake Union, at 1602 N Northlake Way, Seattle. Starting in 1925, the site was a bulk petroleum fueling terminal. It has three areas: two tax parcels and the public right-of-way (ROW) between the two tax parcels. The two parcels are referred to as the North Yard and the South Yard. The South Yard had a warehouse, two docks, and a railroad spur. The North Yard contained aboveground storage tanks for petroleum products, transfer piping, loading racks, and various small buildings.
In 1999, King County Metro and Chevron entered into a consent decree with Ecology. In 2009, Metro sold the North Yard property to Touchstone NLU. The 2007 prospective purchaser consent decree (PPCD) required a limited cleanup of contaminated soils within the North Yard property line. In 2016, the Touchstone NLU portion of the site was given a No Further Action determination for soils within the North Yard. Ecology determined that the requirements of the 2007 PPCD had been satisfied and the PPCD was dismissed. The 1999 Consent Decree remains in effect for soils outside of the North Yard and groundwater throughout the site.
