M N. M mY W. We i nsve asety ruoloved your hear of Nov. 22,1998 in which tir. harague denied my request that me SoNSS be immemetely shut does ponen0 a more thorough review of the sehmic deks.

I was told West there would be a peelen proosse during whidt I assumed that I wedd be able to

psesent information and date. I now assume that the request for a shuttown is separate tem the i petMon process and West is why your denial was leeued Gret.1 Wilnk Stat you should have at least j ist me autant somethin0 before this dodelen was made.

Mr. 48reOlia then used some other SCE dela to substantiste his denial and hasty conclusions He stated that there is insufflaient evidence to warrant immediate acthm, but I have not had the chonos to submit any evidonos yet! He also elated that he wig evaluste my age 0sNons, but I have not even had the chenes to submit any yet! Even if my request is to sepended into two i parts, an smargency part and a lengthier potillon process, R should be snede clearer to whom l, and when information is to be submlued i i have enclosed a heter paper on etw unowtainties or seismic niek needesino . This is omy sw 1 beginning at what we be presented. I we aho submt an ousne of the rnsterlei to be presented neer i enske corredians or addnions to the No*M that is eming pubashed in the Federal Reghter7 No information was included about this part rj #w prooses other.

er these procedursi misunderstananos and teceos are typical of your hendun0 of emergency and alhar aquests, I prey they improve before we amoede. W ehey are inecouve of a systemsee ademostremve prehism, then not only is s. Campomie in denser, but se rest of the country.

set was taken from a recent paper by M.D. petersen, et al, (Seismic Hazenf Anseyels, AEG,1-j ases). Their canoeuelon that me enere t.as An0stes, ventwo and orange Counces are high nesent erees. Acceleremons of 0.de (pDs),1.ca (o.Seec SA), and 0.5e(1.eec SA) een occur esody everywhus. 640her acostereuons occur near an of the known faut zones. Simber fl0ures oeutd be estoubted for omer areas in S. Coluomie, such as San Diego, W. Riverside, San

They also conomde that even mou0h mese askedssons am bened on a tooed consensus of

~aent sciengAc opinion, numerous uncertainties selet in assumptions about most of the key pommsters. The modnes are sensys being odeesd sah each event. This is charactedstic of the edstory of me science. 40 years a0o, we dient even know that the San Andnes Fault had oRests of ever 300 mues! Yes, we have come a long way towenis underelanen0 to spectander geology and tectonics of S. CaNomie, but Wiem are sel a lot of things we need to know to enske certeln artices decisions on maior construction projects, post and present. We need to continuesy upgrade the colouleuons because #te awareness of the seismic eleks is so dramatically incrossed wth each event.

The esveral diesserous earthquakes we have had in S. Coelfomie were fun of surprises and we were adually very lucky we edn't have greater loss of IWo. These events are the womings that we should heed before an even greater estastrophy occurs. We must plan for the mitl0stion of an event gmotor then any recently expertenced on our local emell faults. We must propers for a gaat event on the Sodhom San Andress Fault. This event could emelly be l>8, and wEl probably be much greater then the San Francisco Quake, h>8+.

There are a lot of things we shouki do as soon as posetile. Some are docussed below.

Not only should the plant be tempodly shut down, but also the weste store 0s situation should be i

doet wth as an "Immedlete Emegpacy Hazant". The weste should be prepared for transport out of tie 8. Catfomis Seismic Zone. I believe that severed temporary abas are aveNeblo.

Almost anypteos is safer then in a pool at the boed! This foollity for storing weste was never

! desi0ned for the current unapes and this is totally unarmfda* and a violation of numerous I rules, regulat'ons, laws, human rl0 hts and basic common sense. The weste should be kW as

We need to set the esemple for other feelities. This operation should tie state of the art. If this leni posette, then it should be shut down pennenently.

i helgions of people are at nok, the Pacinc Ocean is et risk and the future of Amerlos is at risk.
