SUBJECT:

 

Model Toxics Control Act Agreed Order for remediation of the Lora Lake

ACTION REQUESTED 

 
Authorization for the Chief Executive Officer to execute an Agreed Order with the Washington 
Department of Ecology (Ecology), issued under the Model Toxics Control Act (MTCA), for 
environmental investigation of and evaluation of remediation methods for the Lora Lake Apartments 
property. 
 

SYNOPSIS 
 

Soil and ground water at the Lora Lake Apartments site was contaminated prior to the Port of Seattle 
gaining ownership.  The contamination is the result of former industrial operations from the 1940s – 
1980s.  Remediation of the contamination is required by state law, and is necessary for productive 
reuse of the site by future redevelopment or other actions. 
 
Preliminary investigations performed as part of the Third Runway project have defined the general 
character of the contamination.  The Port has used the results of these investigations as a basis for 
protecting against mobilization of contaminants from the site.   
 
The Port has negotiated with Ecology to define the scope of an Agreed Order under which the Port 
will protect the site from contaminant migration during demolition of the existing apartment building 
above-ground structures, and then perform a Remedial Investigation (RI) and Feasibility Study (FS). 
The results of the RI/FS will form the basis for site remediation.   
 
Authorization of expenditures for the Lora Lake Apartments property environmental management 
activities were previously approved by the Commission in its 2009 Port Environmental Reserve 
spending authorization of December 15, 2008.  No additional authorization of funds is being 
requested at this time.
