Release of PCBs during dredging much worse that expected
ALBANY — Dredging a portion of the upper Hudson River released almost 25 times more PCBs into the water than expected, General Electric said Thursday in calling for changes in performance standards before the massive Superfund cleanup resumes.
GE and the U.S. Environmental Protection Agency each released draft evaluations Thursday of last year’s dredging of PCB “hot spots” north of Albany. The dredging was a test run for the far larger Phase 2 of the cleanup, which regulators want to start in 2011. The second phase of dredging would represent about 90 percent of the cleanup and could take five years.
