Description In April 2016, the Washington State Department of Ecology compiled a draft list of frequently asked questions (FAQs) for public comment. The comments Ecology received were addressed and the FAQs were finalized in June 2016. See link to “Response to Comments,” above.

In October 2016, Ecology removed the “Draft” watermark from Attachment A. No other changes were made to Memo No. 15 published in June 2016.

The FAQs are intended to address several policy issues related to using empirical demonstrations for contaminated site cleanups. The FAQs are also intended to provide sufficient information for completing an empirical demonstration in accordance with the provisions in WAC 173-340-747(9). This document can be used at any cleanup site that meets the requirements for empirical demonstrations, including Ecology-supervised sites and independent cleanup sites.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
