The PownPownal Dam 5.5.12 035al Tannery site is located on the Hoosic River in North Pownal, Vermont. Previously at the site there was an eighteenth-century grist mill was followed by a mid-nineteenth-century woolen mill, a cotton mill and finally a tanning company. The dam has been inactive since 1988.

For over 25 years while the tanning company was in operation, wastewater from the tanning process was discharged directly into the Hoosic River. This affected the Hoosic River to such a negative extent, that swimming in the river and eating local fish became a health risk. In 1999 the EPA placed the Pownal Tannery site on the Superfund program’s National Priorities List. Hoosic River Hydro conducted an Environmental Site Assessment Report in 2015, and is beginning with Brownfields clean up in 2016. The capacity of the site will be restricted to 500MW in order to join the Vermont Group Net Metering program.
