DearMr Pate:

Enclosed is a copy of the Humboldt. Bay Power Plant Update newsletter which will be sent to people living within ten miles of the power plant during September,1993. As required by the Nuclear Powerplant Communities Information Act of 1985, this newsletter is distributed once every two years. This is the third publication. Again, your agency has been listed as a resource for people who would like more information about the plant's status and any discharges.

Sincerely, Edward V. Waage Supeivisor Emergency Planning EVW:dag Enclosure 1,
