transit distance for vessel
response plans for COTP San Francisco using the Sonoma County Airport as the primary
dispersant staging point. Using a Geographic Information System as in this example, or
manually with a nautical chart, the distance from the staging point to the furthest extent
of the 50 NM off shore contour is measured as 94 nautical miles. This is entered as the
One Way Transit Distance in the DMP2 to calculate the EDAC value for a specific
platform within the San Francisco COTP zone using the Sonoma County Airport as the
primary dispersant staging site.
