The Department of Environmental Protection seeks public comment on proposed amendments to Chapter 150, Control of Emissions from Outdoor Wood Boilers. The Department is proposing reduced setback and stack height for outdoor pellet boilers meeting a 0.06 lbs/MMBtu heat output emissions limit. The proposed particulate emission standard is for determining a reduced setback and stack height only and is not a standard for controlling or limiting the sale of outdoor pellet boilers. The Department is especially interested in comment on the 0.06 lbs/MMBtu heat output emissions limit, and whether an alternative emission limit is more appropriate. Comments are due February 20, 2009. http://www.maine.gov/dep/air/regulations/docs/pbnotic150.pdf. for announcement, and http://www.maine.gov/dep/air/regulations/docs/chap150postsjan152009b.pdf for text of amendments
