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-Cleanup/Contamination-
cleanup/Cleanup-process/Cleanup-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:

Thank you for considering these comments from Ecology. For
assistance and information about Tacoma Smelter Plume and soils
contamination, contact Diana Ison with the Toxics Cleanup Program at
