Subject: RE: Tri-Met Powell Garage, ECSI 6113
Importance: Normal
Attachments: Affected Area.jpg; Close-up of weeping.JPG; Parking lot.jpg; What we believe to be diesel fuel or a similar oil is weeping up between the joints in the concrete. Unfortunately Trimet has not investigated any further after an initial geophysical survey to look for a potential source (none identified). The pavement was potentially earmarked for removal/reconstruction last summer which would have permitted closer inspection of the issue and removal of contaminated media but this was put on hold. The weeping is occurring on the southern end of the parking area and extends for several hundred feet (see photos and diagram). From: Steve L.

Information available online is limited “oil weeping from the ground”. Can you provide additional site information concerning where the area of concern is located, its extent, etc? Thanks. Steve L.
