Environment (Air Quality)

This bill amends Maine's regulations for outdoor wood and pellet boilers. It allows boilers meeting a new particulate matter emission standard (0.32 pounds per million BTUs) to avoid property setback requirements, as long as they meet stack height rules set by the Department of Environmental Protection. The bill also prohibits the department from creating rules that ban smoke plumes from these boilers, regardless of whether smoke crosses property lines. This directly affects Maine homeowners and businesses using outdoor wood or pellet boilers for heating. The changes aim to make cleaner-burning bioenergy systems more accessible while maintaining specific emission and operational standards.
