Description This memorandum provides petroleum vapor intrusion guidance from the Washington State Department of Ecology (Ecology). To ensure consistency with the Model Toxics Control Act (MTCA) and Ecology’s previous petroleum vapor intrusion guidance, this memo proposes several changes to the vapor intrusion data tables in Ecology’s Cleanup Levels and Risk Calculator (CLARC). You’re invited to comment on these proposed changes through September 22, 2017. Submit your comments to Mark Gordon at marg461@ecy.wa.gov or via website above.
This draft memo was revised in November 2017 by adding a formerly missing row to Table B-3. No other changes were made to this draft.
REQUEST A COPY 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.
