Sullivan Environmental Consulting, Inc. performs dispersion modeling to support permit applications, including Prevention of Significant Deterioration (PSD) permits, state air permits, and modeling to support Title V.

Obtaining the necessary air quality permits to construct or modify a facility can range in difficulty from routine to extremely complex. Complications arise in situations where there is difficulty demonstrating compliance with national ambient air quality standards, state air toxics guideline values, or increments. In difficult situations such as these, experience in emissions assessment and dispersion modeling analysis is critical for successful and cost-effective consulting support. In addition, we are affiliated with firms that specialize in emissions assessment, air pollution control evaluation, permitting issues, and other engineering skills needed to provide comprehensive air quality support.
