We are inviting public comment on cleanup documents for the Carson Cleaners cleanup site.

We invite you to review and comment on the following documents:

  • Draft Agreed Order: This legal agreement requires the potentially liable persons (PLP) to:
    • Investigate and describe contamination (Remedial Investigation).
    • Analyze cleanup options (Feasibility Study).
    • Develop a draft Cleanup Action Plan (dCAP). The dCAP describes how the selected cleanup alternative will be performed.

The public will have another chance to make public comments after these documents are created. 

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 owners of the property, Tahn Associates LLC is a PLP in this cleanup. 

Chemicals present in soil and groundwater: 

  • Halogenated Volatile Organic Compounds (HVOCs)
    • Trichloroethylene (TCE) 
    • Tetrachloroethylene (PCE) 
    • Vinyl chloride (VC) 
    • 1,1-dichloroethene and 1,2-dichloroethene, known collectively as dichloroethene (DCE)
