MassDEP publishes these as percentages rather than volumes, so no dollar figure is derivable from this source. The volumes are in this system's own Annual Statistical Report.

Figures are as filed unless stated otherwise. If a number here is wrong it is wrong in the filing or wrong in
our reading of it, and both are worth knowing: ammar@municorn.us
