Our project, a small non-profit farm house renovation, is using a wood fired biomass boiler. Wood for the boiler is timber blow-down from the 917 acre largely wooded property contiguous to the project site and owned by the same owner. EAc2 allows for "untreated wood waste", but states that "forestry biomass waste" is ineligible. I am making the assumption that blow-down is untreated wood waste and that forestry biomass waste is a by-product of timber management practices. Does anyone want to weigh in????
