Ecology invites you to comment on an Agreed Order (legal agreement) and Public Participation Plan for the Carson Cleaners cleanup site (Site). The Site is located at 4701 Brooklyn Ave NE in Seattle’s University District neighborhood.

The legal agreement between Ecology, Tahn Associates LLC, and Carson Cleaners requires the Potentially Liable Persons (PLPs) to conduct a Remedial Investigation and Feasibility Study, and prepare a Draft Cleanup Action Plan. Ecology would like your input on:

·        Draft Agreed Order: This legal agreement requires the PLPs to investigate and describe contamination (Remedial Investigation), analyze cleanup options (Feasibility Study), and develop a draft Cleanup Action Plan (dCAP). The dCAP describes how the selected cleanup alternative will be performed. The public will have a chance to make public comments after these documents are created.

·        Public Participation Plan:  This document explains how people can participate in the cleanup process.

Ecology will accept comments on these documents from April 26, 2021 – May 25, 2021. For more information on the Site, contact the site manager. If ten or more persons request a public meeting about the above documents, Ecology will provide notice and hold an online meeting for the community.

BACKGROUND

The former Carson Cleaners operated a dry-cleaning business as a tenant on the property from the early 1960s until 2014. During the 2018-2019 environmental cleanup of the Chevron 90129 Site across the street, chemicals commonly used in dry cleaning operations were discovered in the southwestern portion of the Chevron property and along the edge of NE 47th Street. These chemicals were in the form of halogenated volatile organic compounds (HVOC). After studying the groundwater flow direction, it was determined that these chemicals may have come from Carson Cleaners.

Tahn Associates LLC purchased the property in 2012 and is the current owner. As the owners of the property, Ecology determined that Tahn Associates LLC is a PLP in this cleanup.

Contamination

Chemicals present in soil and groundwater:

·        Halogenated Volatile Organic Compounds (HVOCs)

o   Trichloroethylene (TCE),

o   Tetrachloroethylene (PCE),

o   Vinyl Chloride (VC),

o   1,1-Dichloroethene and 1,2-Dichloroethene, known collectively as Dichloroethene (DCE)


STATE CLEANUP PROCESS

 

The Model Toxics Control Act (MTCA) is Washington’s environmental cleanup law. It provides requirements for contaminated site cleanup and sets standards that protect human health and the environment. Ecology enacts the MTCA and oversees cleanups. The MTCA site cleanup process is completed in steps over a variable timeline (see graphic below with current step highlighted in red).
