Air Quality

A Breath of Fresh Air

At GeoInsight, we are committed to the professional development of our staff. Our EHS compliance specialists, scientists, and engineers continue to emphasize staying up to date on the ever-evolving regulatory and technological innovations that apply to air emissions in various industry sectors throughout New England.
Whether you need support with facility design, maintenance, compliance and/or operations, we can provide.


We work closely with you to understand your unique processes, facility layout and challenges. Our goal is to listen to you and to support you in ways that not only meet regulatory requirements but are also easy to implement within your business. From source registration (mobile and stationary) and applicability determinations/exemption analyses, to individual new source reviews and Title V permitting, to greenhouse gas evaluations and reporting, our team can support your in-house EHS staff with your permitting needs.

Air Emissions Inventory and Air Toxics Compliance Determinations

Our air experts work across diverse industries to provide: 

  • Emissions characterization and tracking
  • Regulated Air Toxic Pollutants (RTAPS) evaluations in New Hampshire
  • Maximum Achievable Control Technology (MACT) standards
  • Air modeling
  • Pollution prevention
  • New source performance standard evaluations
  • National Emission Standards for Hazardous Air Pollutants (NESHAPs) evaluations

Air Modeling

Our air emissions modeling capabilities can assist you with facility design, air permit evaluations and permit application. We use the American Meteorological Society/United States Environmental Protection Agency Regulatory Model (AERMOD) to model the dispersion of emissions from stationary and mobile sources. With AERMOD we can account for terrain, land use, meteorology, emission rates, exhaust flow rate/temperature, stack height/diameter, and building geometry.
