The U.S. Environmental Protection Agency says it wants to hear from Vermonters about plans to improve the cleanup of a Superfund site in Burlington.
Starting tomorrow and continuing until August 15th, the EPA wants input on recommended changes to an underwater cap built around the Pine Street Canal site to stem contamination from reaching Lake Champlain.
For 10 years, a plume of contaminated groundwater was stable. But beginning in 2008, benzene concentrations increased and coal tar has been intermittently found at the former gas plant site.
Now, the EPA is proposing the addition of a vertical barrier below the ground surface at the northwestern corner of the site – between the canal and bike path – and it wants public input on the change.
The plan is on the EPA’s web site, at http://www.epa.gov/ne/superfund/sites/pinestreet .
