Relevant Experience

Mr. Smith has been president of Walter Smith & Associates, Inc since 1993.  For 20 years prior to that, Mr. Smith was the co-founder and President of Entropy, Inc., at that time the largest source sampling company in the country.  He is nationally recognized in the field of emission measurement methodology and has over 50 years of air pollution control and testing experience.  Mr. Smith served as the Chief of Source Sampling Unit of the Division of Air Pollution in the Public Health Service before the creation of the Environmental Protection Agency (EPA).  Mr. Smith was largely responsible for the development of both the testing methodology and equipment that subsequently became EPA Methods 1 through 8. These methods were refined in field applications under Mr. Smith's direction. Mr. Smith was also one of the three principal authors of Methods 1-8 and was active in EPA efforts to win their final approval. Additionally, during his 11-year association with the Public Health Service and EPA, Mr. Smith developed and directed the source sampling training courses for the Air Pollution Training Institute (including the 450 course).  He also co-authored more than 40 papers for publication; assisted state and local agencies in the development of air-resource management programs; and performed research studies on air emissions from all types of sources.

He left the EPA in 1972, I co-founded and was President of Entropy, Inc. from 1972 to 1993. While I was president, Entropy became the largest stack sampling company in the country. Since Mr. Smith left the EPA in 1972, he has assisted in the improvement of EPA Methods 1-7,10,13,16, 17, 18, VOST, PM10, MM5, and co-authored the F factors. He has also developed methods such as the 3 dimensional determination of gas flows (now method 2F), enforcement of fugitive emissions, instrumental techniques, and calibration and quality assurance methods.  He is responsible for training thousands of people how to do stack sampling.

He retired from Entropy after 21 years in 1993 started Walter Smith & Associates.  Now, he spends most of his time consulting, overseeing stack tests, reviewing protocols and reports, providing expert testimony or teaching courses about stack emission measurement through Walter Smith & Associates, Inc.
