Corps of Engineers completes Mack Point study

Jan 18, 2013

According to the Dec. 31 Army Corps of Engineers report for Maine, a Congressional Resolution passed in July 2000 at the request of the Maine Department of Transportation called for a study of Searsport Harbor with a view toward deepening he existing 35-foot deep channel in support of port activities at the state and private terminal facilities at Mack Point. The Reconnaissance Study was completed in Sept. 2004. A feasibility cost-sharing agreement was executed with the Maine Department of Transportation in December 2005. The feasibility study costs are estimated at about $800,000 and are cost-shared — 50-percent federal and 50-percent non-federal.

Work on the study began in June 2006 and the Corps held a coordination meeting on the project with state and federal agencies in August 2006. Initial study efforts in 2006 included site surveys for cultural resources and geotechnical conditions. During 2007 additional subsurface testing was conducted and a sediment sampling plan developed. In the spring of 2008 sediment sampling in the channel area was performed and analytical results will be used for the disposal suitability determination. Preparation of the draft feasibility report, including project costs, economic benefits and environmental assessment, was completed in 2012 and is under review. Public review of the draft feasibility study and environmental assessment is planned for 2013.
