Inventory of Emission for the City of Chicago

A review of the methodology used in the development and implementation of a comprehensive emission inventory survey with emphasis on manufacturing plants. This inventory, a major goal in the Dynamic Air Resource Management Program for the City of Chicago, is a principal objective of a Five-Year Technical Assistance Agreement with the United States Public Health Service, Division of Air Pollution and Chicago’s Department of Air Pollution Control. Information obtained through a 75 percent response from a questionnaire mailed to 7312 manufacturing firms provided the basis for this inventory. Data on the delinquent firms was obtained from on-site evaluation by department engineers. This report will also cover computer processing and tabulation of survey data.
