ESS works with clients to develop permitting and compliance strategies that minimize regulatory burdens, maximize operating flexibility, and facilitate business goals. We develop the best permitting strategy to achieve these goals, while streamlining the permitting process to facilitate timely review and approval.

Our staff is expert in conducting emissions control technology analyses (RACT, BACT, MACT, or LAER), with first-hand experience in both traditional and advanced technology control systems. We also bring extensive experience in dispersion modeling to assess air quality impacts and address federal Prevention of Significant Deterioration (PSD) requirements and air toxics limitations, as well as plume behavior and impact studies related to fogging, icing, shadowing, and mineral deposition.

We are experts at developing and analyzing technical data to prepare comprehensive application documents and reports. ESS staff bring many years of experience in developing and managing emissions testing programs to acquire emissions information where established emissions factors may not exist.
