Biomass-burning facilities have been granted a three-year exemption from a new U.S. EPA rule limiting greenhouse gases while the agency studies the effect of plant emissions on climate change, as reported in The New York Times. According to the article, during the exemption period, industrial plants that burn woody biomass and landfills that release the greenhouse gases from decomposing biomass won't need permits before starting construction and won't need Title V operating permits. The final rule is available here.
