BOX 162-171 Environmental Products and Services Company, 1952-2001
The Environmental Products and Services Company (EPSCO) series documents Hall's involvement with this company in the 1980s and 1990s. The company was founded by William J. Armiger Jr. and consisted of a group of independent consultants who pooled their talents to treat large air pollution control and electrostatic precipitation problems. Hall led projects and studies and was referred to as the "dean of electrostatic precipitation" in final EPSCO reports. Technical reports from H. J. Hall Associates were usually incorporated into EPSCO reports for clients. Hall worked closely with Willliam J. Armiger Jr., Philip B. Crommelin Jr., J. Albert Hudson, Jack R. McDonald, and Bill D. Pfoutz on the application, design, and operation of electrostatic precipitators in the electric utility industry. The series showcases EPSCO and Hall's involvement with the hot side to cold side conversion of electrostatic precipitators. In the 1970s, the hot side precipitator concept was developed and thought to be the answer to high-resistivity coals. Eventually, many precipitators began to fail due to inadequate structural design fuel analysis or undersized equipment. Hall and other EPSCO consultants provided inspections, performance predictions and modifications, and recommendations for hot side to cold side conversion of electrostatic precipitators. This series also chronicles Armiger's founding of EPSCON, the engineering and installation company created to complement EPSCO, and further documents the merger of EPSCON with F.L. Smidth & Co. of Denmark into EPSCON-FLS.
Material types include blueprints, brochures, consultant agreements, correspondence, data, drawings, graphs, memoranda, newspaper clippings, notes, photographs, printed matter, proposals, research material, studies, technical reports, and other papers.

BOX 172-185 Writing and Lecture File, 1947-2002
The Writing and Lecture File contains lectures, speeches, and writings reflecting the breadth of Hall's contributions to the areas of air pollution control and electrostatic precipitation. The papers and publications file consists primarily of a chronological file with drafts, notes, and published editions of scientific papers and technical reports. The lectures and seminars file includes a chronological file with drafts, notes, research material, and papers presented at conferences. Also included are topical files containing background data, notes, and research material relating to lectures and seminars presented by Hall. Reflected in the series are Hall and Jacob Katz's collaborations on electrostatic precipitation seminars, which they presented throughout the United States from 1981 to the late 1990s. Thomas R. Keeler later joined them and presented along with Katz on the operation and maintenance of electrostatic precipitators while Hall focused on the technical aspects.
Material types include bibliographies, blueprints, conference proceedings, consulting agreements, correspondence, charts, drawings, graphs, photographs, speeches, supporting material for lectures, reports, and other printed matter.
