The report details the techniques and results of Joint Project studies of atmospheric emissions from eight miscellaneous sources in oil refineries. Because the emissions from these operations or equipment were of a minor nature or were already well defined and understood through previous available studies, independent field testing was carried out in only one of the eight source studies. The estimates of emissions presented were generally based on field inspections, letter surveys, literature surveys, and existing test data or loss estimates supplied by the Los Angeles County Air Pollution Control District or the Western Oil and Gas Association.
