Comments
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 UW Medicine Testing Lab CUP project. Based on review of the
checklist associated with this project, the Department of Ecology
(Ecology) has the following comments: This proposed project is
located in an area that may have been contaminated with heavy metals
due to the air emissions originating from the old Asarco smelter in
north Tacoma (visit Ecology’s Tacoma Smelter Plume map search
tool: https://apps.wa.gov/ecy/dirtalert/). Soil contamination from the
former Asarco smelter poses a risk to human health and the
environment. Children are at especially high risk from direct exposure
to contaminated soil. Construction workers, landscapers, gardeners,
and others who work in the soils are also at risk. Ecology
recommends that the lead agency include the following as conditions
of approval, prior to the issuance of any site development permits or
the initiation of grading, filling, or clearing: • Sample the soil and
analyze for arsenic and lead following the 2019 Tacoma Smelter
Plume Guidance. The soil sampling results shall be sent to Ecology
for review. • If lead or arsenic are found at concentrations above the
Model Toxics Control Act (MTCA) cleanup levels (Chapter 173-340
WAC); the owners, potential buyers, construction workers, and others
shall be notified of their occurrence. The MTCA cleanup level for
arsenic is 20 parts per million (ppm) and lead is 250 ppm. • If lead,
arsenic and/or other contaminants are found at concentrations above
MTCA cleanup levels, the applicant shall: 1) Develop soil
remediation plan and enter into the Voluntary Cleanup Program with
Ecology. For more information on the Voluntary Cleanup Program,
visit Ecology website at: https://ecology.wa.gov/Spills-

options/Voluntary-cleanup-program. 2) Obtain an opinion letter from
Ecology stating that the proposed soil remediation plan will likely
result in no further action under MTCA. The applicant shall provide
to the local permitting agency the opinion letter from Ecology. 3)
Prior to finalizing site development permits, provide to the local land
use permitting agency “No Further Action” determination from
Ecology indicating that the remediation plans were successfully
implemented under MTCA. • If soils are found to be contaminated
with arsenic, lead, or other contaminants, extra precautions shall be
taken to avoid escaping dust, soil erosion, and water pollution during
grading and site construction. Contaminated soils generated during
site construction shall be managed and disposed of in accordance with
state and local regulations, including the Solid Waste Handling
Standards regulation (Chapter 173-350 WAC). For information about
soil disposal contact the local health department in the jurisdiction
where soils will be placed. The link below provides a fact sheet that
explains more how the arsenic and lead clean-up levels were set and
why Ecology sees that they are protective for human health:
