Eric Edwalds

Senior Environmental Scientist

Profile Picture

Eric Edwalds has nearly 30 years of experience with air dispersion modeling, ambient air monitoring, meteorology, fugitive-dust generation and transport, and statistical analysis of environmental data. His dispersion modeling project experience ranges from simple screening analyses to modeling for complex Prevention of Significant Deterioration (PSD) applications involving long-range transport, PSD increment consumption and expansion, visibility, air toxics, and deposition. His work encompasses preparation and negotiation of dispersion modeling protocols, extensive use of geographic information systems (GIS), emission calculations, reporting, and results presentations, as well as analysis of ambient air and meteorological data and “what if” scenarios.

Eric’s recent project work includes conducting modeling for Minnesota's taconite processing facilities to comply with the Minnesota Pollution Control Agency's air dispersion modeling requirements for the long-term strategy portion of the regional-haze state implementation plan. He has also been conducting dispersion modeling for environmental impact statements and air permit applications for refining, energy, forest-products, and mining clients.
