Career Highlights

Since 2009, Stewart has been involved in all aspects of Clean Air Act (CAA) administration including: drafting air quality permits (Title V, Synthetic Minor, Conditional Major, and Construction); preparing applications [Title V Operating, New Source Review (NSR) Preconstruction, and State/Local CAA permits]; developing environmental managements systems and compliance tools; providing litigation support services; negotiating source-specific State Implementation Plan (SIP) requirements; and preparing air dispersion modeling evaluations [National Ambient Air Quality Standard (NAAQS) compliance demonstrations, Significant Impact Level (SIL) determinations, and risk assessments for emissions of toxic air contaminants (TAC)].
Between 2018 – 2020, Stewart led preconstruction air permit application teams which successfully permitted capital projects exceeding $500,000,000 for new “greenfield” stationary sources.

He was the primary author for preconstruction air permit applications on experimental post-combustion CO2 capture systems (PCCCS) collocated with coal-fired electric utility steam generating units. The PCCCS permitted projects were awarded $19,700,000 in funding by U.S. Department of Energy’s National Energy Technology Laboratory.

He provided litigation support services which reduced client administrative penalties by more than $250,000.
Stewart successfully developed technical petition materials (including SIL determinations and NAAQS compliance demonstrations) that identified flaws in a CAA Administrator’s area-wide attainment modeling demonstration which ultimately resulted in the timely redesignation of a SO2 NAAQS nonattainment area.

He has also developed strategic solutions for compliant modeling of TAC emissions for multiple PSD sources subject to human health risk-based emission standards within the Louisville Metro Air Pollution Control District Strategic Toxic Air Reduction Program.
