AIR QUALITY DISPERSION MODELING

Weston has the qualified, technical resources, and industry experience to conduct air dispersion and deposition modeling in support of air quality permitting, air toxics, risk management, and visibility analyses. Weston has conducted specialty projects for clients, such as complex terrain dispersion modeling, accidental release, and cooling tower icing/fogging studies.

AIR POLLUTION CONTROL ENGINEERING

Our air quality experts have broad expertise in technical and economic evaluation of air pollution controls, including process optimization to reduce emissions, material substitution, and add-on controls, such as fume incineration, catalytic oxidizer, carbon adsorption, absorption, thermal and catalytic NOx reduction, fabric filtration, electrostatic precipitation, and scrubbing. Weston provides the following air pollution services:

COMPLIANCE AUDITING

Weston brings senior air staff highly experienced in performing audits of clients’ compliance with federal, state, and local air regulations and programs and due diligence audits (prior to or subsequent to) mergers and acquisitions.

SITING/LICENSING/PERMITTING

Weston conducts facility siting studies for clients to determine the best location for new construction or facility expansion, including the siting of wind energy facilities. Siting studies may include an assessment of the schedule and cost to obtain environmental permits and the need for baseline monitoring and on-site evaluations. Screening dispersion modeling and permitting reconnaissance are often included in the study to assess data collection requirements and identify potential “fatal flaws” for a site.
