Tim, who has more than 30 years of consulting-industry experience, established Barr’s air-quality testing practice in the early 1990s and now oversees projects involving stack testing and ambient air monitoring, as well as wind-resource assessments and meteorological monitoring. He has managed or participated in hundreds of stack tests encompassing the full range of U.S. Environmental Protection Agency test methodologies for clients in the mining, power, forest-products, manufacturing, pharmaceutical, and agricultural sectors. By providing stack-testing training to Barr staff and clients, he creates a shared understanding of methodologies and responsibilities that fosters successful projects.
Tim helps clients respond to air-emission challenges by evaluating control-device performance and the process variables that can influence pollutant emissions, and by translating stack-testing data into meaningful information for use in developing site-specific corrective actions. His experience also includes measuring the effectiveness of technologies that reduce mercury emissions to the air. In addition, he has participated in numerous research and engineering test projects, such as one in which multimedia testing was used to measure emissions of perfluoroalkyl substances (PFAS); the data were then incorporated into mass balance calculations to characterize emissions across an entire industry.
