Feasibility Study

DESCRIPTION:

A 250 MMBtu/hour wood-fired power plant proposed for a site in Randolph. Tech was charged with identifying the potential emissions, estimating emissions, and modeling these emissions offsite through complex terrain. Complex terrain is defined as off-site receptors that are located in higher elevations than the original stack or source. Modifications are necessary to the traditional Gaussian dispersion models to account for this complex terrain. On-site meteorological data was collected to characterize the air flow in this unique complex terrain. Air permitting included: examining potential offsite impacts, as well as a control technology assessment, and start-up and compliance visibility and air monitoring requirements. Emissions from the adjacent Vermont Castings plant were also incorporated to consider the combined potential emissions.

Key Points

• Emission estimating, dispersion modeling, and an impact assessment was completed for a wood-fired plant and nearby Vermont Castings plant
• An air permit was completed for the new wood-fired power plant
