NCASI technical reports NCASI is an organization that supports environmental science and data to promote the sustainable use of resources and has technical expertise in developing emission factors for the forest product industry,
scenario. The HAP emission factors for ABBK are taken from EPA’s Chapter 1.6: “Wood Residue Combustion in Boilers,” whereas We Energies’ permit only lists an HF emission factor, which is higher than that reported by ABBK.
