Air Quality Permitting
Greenfield’s knowledgeable staff gives our clients a complete and insightful understanding of all of their air quality permitting needs. Our professionals are experienced in ISO 14000, Title V, NSR/PSD, state construction and operating, as well as variance and specialty permits. The permitting naturally includes MACT/BACT/RACT/LAER issues where appropriate. Accurate, complete and timely permit applications, coupled with our relationships with EPA and state regulatory personnel, help to prevent potentially expensive red tape delays and ensure that your permit application receives the prompt attention desired.

Dispersion Modeling
Greenfield Environmental’s modelers are experienced in all aspects of dispersion modeling. Our engineers have modeled for criteria, hazardous and Title III high-risk pollutants using numerous EPA dispersion models, including ISC, SCREEN, DEGADIS, PUFF, FDM, etc. We have disputed and beaten state agency “experts”, established new air sheds for polluting sources, identified individual sources as primary origin of specific pollutants, defined risk levels of hazardous pollutants for new and modified sources, determined levels of control required and/or new source locations and/or stack and building heights to ensure regulatory compliance, and many other interesting projects. Experience with the dispersion models and knowledge of the regulations involved make Greenfield Environmental a valuable asset in addressing your air quality concerns.
