"Decommission Ground Water Monitoring Well Located on Bonneville Power
Administration (BPA) Fee-owned Property
CX(s) Applied: B3.1
Date: 12/14/2011
Location(s): Washington
Offices(s): Bonneville Power Administration
Bonneville Power Administration (BPA) proposes to allow Seattle City Light access to a BPA fee-owned right-of-way (ROW) for the purpose of decommissioning a Seattle City Lightowned well. Seattle City Light historically installed ground water monitoring wells as part of the Boundary Dam licensing process in the 1950s and 1960s to study the impact of the Dam on ground water levels. One of these wells exists on BPA fee-owned ROW approximately 650 feet ahead-on-line from tower 107/1 [Ref Bell-Boundary #3]. Seattle City Light will hire a contractor to perform the work in accordance with the requirements for well decommissioning in the Washington Administrative Code 173-160-381. The project will involve the use of a trackhoe to pull the top 4-feet of well casing then the well will be grouted closed with a stable filler material such as bentonite. The contractor will be required to restore the site and remove any man-made materials from the site upon completion."
