This guidance was created to encourage cleanup of Asarco contaminated soil during property development. It provides straightforward directions on soil sampling and cleanup of soil contaminated with arsenic and lead within the Tacoma Smelter Plume. In July, we launched a revised version of the guidance, replacing the older, 2012 version.
The guidance was written primarily for developers who build residential housing or commercial buildings. However, anyone who wants to sample and clean up their Asarco contaminated soil within the Tacoma Smelter Plume can use this guidance. The guidance streamlines the sampling and cleanup process and eliminates the need to develop separate sampling and cleanup plans. When developers use the remedies covered in this guidance to clean up their properties before building structures, Ecology is able to issue timely opinion letters stating that the cleanup meets state requirements.
