STI has supported a number of industrial clients by developing site-specific air monitoring programs to assess compliance with relevant regulations and to inform litigation-related issues. STI’s technical work for our industrial clients has also included short-term field studies, data analysis, emissions assessment, and air quality modeling, and we have also participated in negotiations between our private clients and regulatory agencies. Types of industrial clients assisted include bulk material handling facilities, landfills, petroleum refineries, and oil and gas operators.
