Dear Alex Morganroth:
Thank you for the opportunity to provide comments on the State Environmental Policy Act
(SEPA) notice of application utilizing the optional determination of nonsignificance (ODNS/NOA)
process for the Taxiway A Reconstruction/Rehab and Associated Improvements Project. Based
on review of the checklist associated with this project, the Department of Ecology (Ecology) has
the following comments:
We recommend the following updates be made to the Environmental Checklist:
Section B, Environmental Elements; Subsection 7, Environmental Health.
The proposed SEPA project is located adjacent to two contaminant sites listed on the MTCA
Confirmed and Suspected Contaminated Sites List: Renten Municipal Airport Fire Training Area
(cleanup site ID 2546, facility site ID 20554), and Cedar River Trail (cleanup site ID 2857, facility
site ID 39825723). Historically, soil and/or groundwater on these cleanup sites are
contaminated with metals, chlorinated volatile organic compounds (CVOCs), and
polychlorinated biphenyls (PCBs).
Please add the contamination information in the checklist. Please 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 and groundwater encountered during
excavations, including sampling, containment, and disposal at a permitted facility.
