This document is one volume of a sixteen-volume report presenting an overall assessment of the particulate problem, which was conducted by GCA/Technology Division for EPA. This particular document is one of fourteen single-area volumes that provide working summaries of data gathered in the fourteen urban areas studied. These city reports primarily provide documentation and background information for Volume I of the study - National Assessment of the Particulate Problem - Final Report (PB-263 665). Volume I should be considered the primary output of the report. For the purpose of this study, major attention was directed at that portion of the region under the authority of the Bay Area Air Pollution Control District. The total land area within its jurisdiction is over 5600 square miles with almost 500 square miles of water surface area. The center of the AQCR is the San Francisco Bay, a large shallow basin ringed by hills as high as 2000 feet which tapers into a series of sheltered valleys. This topography gives the area great potential for trapping and accumulating air pollutants.
