Comments
We recommend the following updates be made to the Environmental
Checklist: Section B, Environmental Elements; Subsection 3, Water;
subsection b, Groundwater. Based on Subsection 1 subsection c,
“Groundwater was observed as shallow as 4 feet from existing
ground surface” at the proposed project property. Please provide
information about how deep the excavation will be conducted during
the project, and if dewatering is needed to address the shallow
groundwater. If dewatering will be conducted, please provide the
details about permitting, water handling and disposal. Section B,
Environmental Elements; Subsection 7, Environmental Health. The
proposed project is located on a site listed on the Model Toxics
Control Act (MTCA) Confirmed and Suspected Contaminated Sites
List – Boeing Renton BFE Building (cleanup site ID 14577, facility
site ID 12083). Historically, groundwater and soil vapor at this
cleanup site is contaminated with petroleum hydrocarbons, metals
and volatile organic compounds (VOCs). The current data is available
in the Revised Remedial Investigation Report, dated May 5, 2021.
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.
• Impacts of the construction project on ongoing contaminant
remediation at the site, including procedures to prevent damage to
site monitoring wells. Thank you for considering these comments
from Ecology. If you have any questions or would like to respond to
these comments, please contact Jing Song from the Toxics Celanup
Program at (425) 229-2565 or by email at jing.song@ecy.wa.gov.
