The report gives results of a 3-year program to assess the environmental impact of petroleum refining atmospheric emissions. This volume contains Appendices C, D, and E. Appendix C presents the quality assurance program and a statistical analysis of the emissions data. It describes quality control procedures for screening, sampling, analyzing, species identification, and data validation. It discusses the accuracy and precision of the various data types. Appendix D describes the procedures used to develop a detailed environmental assessment of refineries. Refinery emission rate data were used to predict ambient pollutant levels near a model refinery. The environmental effects and the potential hazard to the public are discussed. Appendix E is a detailed review and evaluation of pollution control technology. The state-of-the-art of fugitive and process emission controls in refineries is reviewed. Available controls are described. Control technologies used in related industries are examined for potential applicability in the refining industry.
