the COTP zone
could be divided into two areas by a line equidistant from the two airports. The diagram
shows the San Francisco COTP zone with a dispersant staging site at the Mendocino
County Airport for the northern area of the COTP zone with a EDAC Transit Distance of
85 nautical miles and a dispersant staging site at the Half Moon Bay Airport for the
southern area of the COTP zone with a EDAC Transit Distance of 72 nautical miles.
