Consulting services offered by AER in air quality include computer model simulations, data analysis, project management, and litigation support. These services cover a broad range of issues such as air toxics, ozone (and other photochemical smog pollutants), particulate matter (PM2.5 and PM10), visibility degradation (including plume opacity), indoor air pollution, and atmospheric deposition.
AER staff are on the forefront of research, development, and applications for particulate matter (PM) and regional haze issues, providing guidance to the U.S. EPA, state agencies, and major industry groups. AER’s expertise includes the development of new state-of-the-science PM models, application of research-grade and regulatory models, data analysis and design of monitoring programs.
AER has also developed an air quality modeling system for air toxics that has been successfully applied for mercury to spatial scales ranging from the globe to regional watersheds. Other air toxics studies have focused, for example, on dioxins/furans, benzene and diesel particles.
AER staff have hands-on experience with all the photochemical
smog models currently used for regulatory applications and have
applied advanced versions of those models to provide more accurate
assessments of air quality impacts. In addition, AER has conducted
extensive data analyses to understand the processes that govern
ozone and PM formation. AER has installed air quality models at
the facilities of clients and provided on-site training of future
users.
AER also offers consulting services in risk assessment. These
services include the application of existing techniques for conducting
public health and ecological risk assessments of routine and/or
accidental releases, the development and use of more refined approaches
to risk assessment including probabilistic analyses, and litigation
support. AER scientists and engineers have conducted regulation-driven
health risk assessments for a large variety of facilities including
refineries, incinerators, hazardous waste transfer, storage and
disposal (TSD) facilities, oil production fields, power plants,
marine terminals, research laboratories and hospitals. All those
risk assessments have been approved by the responsible regulatory
agencies. If needed, AER staff will meet with regulatory agencies
and the public to present and explain the results of the risk
assessments.
