Air Permitting and Regulatory Assistance


For over 40 years, TRC has supported clients with every aspect of air quality systems design, permitting, licensing, compliance assistance and engineering, as well as auditing, due diligence review for asset acquisitions and litigation support and expert witness services. As a result of our broad experience and up-todate regulatory information, we can handle the largest and most complex air projects to save our clients time and money.


The Clean Air Act Amendments (CAAA) and subsequent regulations established by the EPA provide the basic framework to protect human health and the environment by addressing our country’s most pressing air quality issues. These federal laws and regulations are supplemented with state and local regulations. TRC is a nationally recognized leader in the air quality industry, having successfully completed thousands of air quality projects, complying with federal, state and local requirements. TRC maintains the technical expertise, experience, innovative personnel, and in-depth regulatory knowledge needed to tackle the complex issues raised by the CAAA. TRC air staff have been advising our clients on the potential impacts of the newly promulgated and proposed regulations as noted below. Each of these regulatory requirements must be taken into account in the overall air permitting strategy for a facility.
