Cleanup plan revised for Sea-Tac Airport sites in Burien and SeaTac
Comments sought; meeting set on plans for former apartments and Lora Lake

BURIEN – The Port of Seattle would remove or contain contaminated soil and sediment on its property at the former Lora Lake Apartments in Burien and nearby at Sea-Tac Airport in SeaTac under revisions  to a proposed legal agreement between the port and the Washington Department of Ecology.

Ecology is gathering public comments on the proposal and related documents through June 17, 2015, and will hold a public meeting to explain and answer questions about the draft plan.

Proposed cleanup plan
The draft agreement, called a consent decree, and cleanup plan reflect public comments Ecology received on earlier proposals, issued in 2013. Work under the revised proposal would begin in 2017.

The contamination came from industrial activities that pre-dated construction of the apartment complex, later purchased by the airport as part of a safety zone for the Third Runway.  Lora Lake is an artificial lake where groundwater filled a former peat mine.

The proposal divides the cleanup – to be overseen by Ecology – into three parts and includes these actions:

Companion stormwater project
A city of Burien storm drain conveys stormwater from a 78-acre area upstream of the former apartment complex to Lora Lake. Burien proposes to re-route this storm water to a Low Impact Development infiltration facility south of the former apartment complex. Ecology has offered Burien a $1.45 million grant for this work as part of a Water Quality Financial Assistance program.

The cleanup proposal includes an alternate stormwater management plan in case the city stormwater project does not proceed.
