Dear Jill Ding:
Thank you for the opportunity to provide comments on the Tiger Food Processing Facility.
Based on review of the State Environmental Policy Act (SEPA) checklist associated with this
project, the Department of Ecology (Ecology) has the following comments:
Section B, Environmental Elements; Subsection 7, Environmental Health.
The proposed project is located on a site listed on the Model Toxic Control Act (MTCA)
Confirmed and Suspected Contaminated Sites List – Graphic Packaging International site
(cleanup site ID 11481, facility site ID 14693954).
Soil and groundwater immediately adjacent to the building was contaminated with chlorinated
solvents including trichloroethene (TCE), cis-1,2-dichloroethene (cis-1,2-DCE), and vinyl
chloride (VC). Sub-slab soil vapor samples and indoor air samples collected inside the building
contained benzene, 1,2,4-trimethylbenzene, and/or acrolein above the MTCA cleanup levels.
Ecology recommends that the proponent update the checklist to add the contamination
information, and describe mitigation measures to address the following:
Hazardous waste operations worker training, health/safety plan, and site control
requirements, per WAC 296-843.
Management of potential contaminated soil encountered during excavations, including
sampling, containment, and disposal at a permitted facility.
