Summary of Expertise:

Listed with other top experts in: 

AIR POLLUTION MEASUREMENT; ENVIRONMENTAL AIR SAMPLING; EXHAUST EMISSION MEASUREMENT. Expert co-founded Entropy, Inc., the largest air source sampling company in the country and was its President for 20 years. He is nationally recognized in the field of emission measurement methodology and has 33 years of air pollution testing experience. While at the EPA, Expert was largely responsible for the development of both the testing methodology and equipment that subsequently became EPA Methods 1 through 8. He went on to become the principal author of Methods 1 through 8 and developed and directed the source sampling courses. He also authored numerous emission measurement papers for publication. Since leaving the EPA in 1972, Expert has assisted in the improvement of most of the EPA's methods and co-authored the F-factors papers.

SMOKESTACK ANALYSIS; SMOKESTACK EMISSION; SMOKESTACK FLOW. Expert has worked extensively with smokestack emission analysis. He developed a method for calculating power plant emission rates and has published writings on the determination of fluorides in stack gases, methods to interpret stack sampling data, and field checking meter calibrations on EPA-type sampling trains.

EMISSION CHARACTERIZATION. Having sampled thousands of power boiler smokestacks, Expert authored two extensive research projects that characterize coal and oil emissions. He developed the F-factor, which converts emissions concentrations into weight per unit heat values, from which most combustion regulations are written. He has also authored six papers on combustion emissions.

AIR ANALYSIS INSTRUMENT; AIR-POLLUTION MONITORING EQUIPMENT; POLLUTION GAS ANALYZER. Expert co-founded Nutech Corporation in 1974, a smokestack sampling instrument company. He was Vice President of Nutech from 1974 to 1976 and designed the company's first products. These instrument designs are still the standard of source sampling equipment today. He also authored six air-sampling equipment papers for publication.

PARTICULATE MONITORING; PARTICULATE TESTING. Expert was largely responsible for developing both the testing methodology and equipment that subsequently became Method 5, which is EPA's method for measuring particulates. These methods were refined in field applications under Expert's direction. He was also one of the three principal authors of Methods 1 through 8 and was active in the EPA's efforts to win their final approval. In addition, during his 11-year association with the Public Health Service and EPA, Expert developed and directed the source sampling courses for the Air Pollution Training Institute.
