Oil is shipped to Cyn Environmental in Stoughton, MA for recycling and resale for industrial burners.

In 2006, this included waste paint, transformers (536 were disposed), and universal waste.

Hazardous Waste (lb)

10,306 (includes PCB waste)

15,015 (does not include PCB waste – see below)

Oily solids are shipped to BFI-Niagara Falls which is a Class C Subtitle Landfill.  Mercury bulbs are shipped to Complete Recycling Solutions in Fall River, MA for reclamation

We manage our hazardous waste in compliance with applicable regulations and practice hazardous waste minimization efforts, to the extent possible. 

The majority of waste was oily absorbents and debris from vehicle maintenance and our power generating plants.  Other hazardous wastes generated include mercury waste from broken light bulbs, citrus-based solvents contaminated with oil and grease, and a waste fuel/water mixture. [EN31]

Universal Waste (lb)

2,794

1,795

All UW are shipped to Complete Recycling Solutions in Fall River, MA for reclamation

Universal waste is recycled.  Types of universal wastes generated include batteries, mercury-containing light bulbs, and light ballasts.

PCB Waste (lb)

Included in hazardous waste data for 2005, above.

34,955

PCB wastes are shipped to the TCI facility in Pell City, AL for incineration.

Includes PCB waste with >50 ppm PCBs, which is regulated as VT01 waste.  Green Mountain Power has been actively trying to increase the amount of PCB waste generated, because this means that the PCB oil is being phased out of equipment and replaced with non-PCB oil.  While this does increase disposal costs, it is better environmentally to reduce the overall amount of PCBs in use.
