Project Details

Environmental Partners, Inc. (EPI) performed extensive environmental investigations and remedial actions at several contaminated in-town properties in Port Gamble, Washington. EPI obtained no further action (NFA) determinations from the Washington State Department of Ecology (Ecology) for all of the in-town properties including a former gasoline/service station and a mortuary.

EPI was retained by Pope Resources to investigate oil seeping from the hillside behind the historical general store and museum in Port Gamble. Using a combination of geophysical surveys and targeted test pits EPI identified two 40-foot-long, single wall, leaking underground storage tanks that were likely installed in the early 1900s. The tanks contained Bunker C fuel oil and the released Bunker C followed abandoned product distribution piping and utility corridors. EPI designed and oversaw the removal of impacted soils and installed groundwater monitoring wells to demonstrate, to Ecology’s satisfaction, that groundwater was not impacted by the Bunker C release. Based on the site characterization and remediation work EPI successfully obtained an NFA determination for the site.
