Air Quality Impact Assessment * Climate Change Analysis * Health Risk Assessment
Air quality assessments for industrial and land use development require an understanding
of the emission sources, viable control strategies, and the science and art of realistically
modeling impacts. Innovative mitigation is also necessary to protect the environment and ensure
regulatory compliance. Aspen personnel have decades of combined experience providing air quality and
related services for a wide range of projects types including electricity generation, transmission lines,
pipelines, rapid transit, and airports, for a variety of government and industrial clients.
