My thanks for your thoughtful reply of December 2 (Attachment A) to the November 4 letter of the Concerned Cal Poly Faculty and Staff addressed to NRC Chairman Palladino regarding two specific reasons for the lack of public confidence in the Emergency Response Plan for the Diablo Canyon Nuclear Power Plant. It is indeed heartening to receive such a personal and courteous letter; we are most appreciative.

In your last paragraph you kindly wrote: "Please feel free to contact us if you wish to provide further data reflecting on your concerns . . . " Without wishing to be a burden to your office, I'd like to update one of the concerns mentioned in our November 4 letter and bring a new chapter of another, older concern to your attention.

One of our concerns in our previous letter was with an often flooded area known as the " Twin Bridges" or " Twin Trestles". Money to replace the bridges was said to be unavailable for at least three years. According to the Telegram-Tribune story of November 15 (Attachment B), County officials apparently realize a problem exists on one of only two ways out of Los Osos / Baywood Park (the other route is a two lane road leading into the city of San Luis Obispo which is also subject to flooding) and they intend to rebuild the Bridges. Unfortunately, the article states that the effort could begin at the earliest in fiscal 1985-86, many, many months after full-power operations at Diablo Canyon are scheduled to be gin.

The other concern we would like to bring to your attention is the continuing problem with si. ens being used as the primary method of notifying the population within the Basic Emergency Planning Zone. P er the Tele gram-Tribune article of March 8 (Attachment C), power is interrupted several times each winter and when electricity is lost, the sirens which "do work off regular power lines", are los t. Whether the explanations offerred by 8312200425 831209 PDR ADOCK 05000275 H PDR

9 December 1983 Mr. John B. Martin Page Two by the PG & E spokeswoman in the article are adequate is something for the NRC, FEMA and the California State OES to decide. We certainly do not believe there is an adequate back-up systern.

We are barely into our winter season and as Attachments D, E and F make clear, power has thrice been disrupted in the area. U ndoubtedly, there will be additional partial or complete losses of power in our area this winter and each time some or virtually all of the sirens will be out of commission. Such back-up systems as expecting everyone to have a battery powered radio at the ready or counting on police cars with sirens to pick up the stack are pale imitations of a fully operating siren system.

Our thanks for your attention to the matters raised. We appreciate your understanding why our group has continuing gravg doubts about the Emergency Response Plan and why public confidence in this Plan is so low.

Sincerely, i
