June 7, 2010 - update: Fort Halifax dam removal and erosion

Monday, June 7, 2010

A Morning Sentinel article today describes how the Maine Department of Environmental Protection is requiring FPL Energy Maine Hydro, the company that removed its Fort Halifax dam in July 2008, to stabilize the riverbank beneath the Fort Hill cemetery.

After years of legal battles, FPL removed the Fort Halifax dam from the mouth of the Sebasticook River in Winslow, Maine. As a condition of its dam removal permit, FPL was required to "closely monitor the slope adjacent to the cemetery and promptly remediate any slumping or erosion" in order "to protect the Fort Hill Cemetery from irreparable harm." Back in April, the riverbank suffered after another major landslides. FPL commissioned a study by Findlay Engineering Inc. of Yarmouth, which concluded that heavy rains and a small earthquake 41 miles away were contributing factors, but largely absolved FPL of responsibility.

Today, the news breaks that the Maine DEP is challenging FPL's study. DEP points to soil loss during the dewatering process, and a resulting lack of work by FPL to re-stabilize the slope after drawdown.
