Dear M!'.'.. Boyd:
30 October 1969 R,ef.erence-is made to yo~r letter.of 7 January 1969 :r:egarding Docket 5o:_:z-zs-r.. Co*n.*sume'rs Pow.er Company Is. ?.alisades. PlaJ:lt' Final Safety Ana.lysis.
. Re(of.. and ;Amendmeri~ Nos.. 9, 10, 11, 12,. 14 * & _15 'thereto. ' Pursuant withe our'. arrangements' :Mr'. R. A. Jachowski of: *CERG has re'vi_ewed this report J:-rom_* trye v~*e"Wp*o~nt.of the evaluation -,of* the d~sign. water.level at *the*
plant site resulting~ from storm surge*_ and *wave. :i;unup_..
. ~.
~.
Frorri *the "tlat~ presented.in the report, it was *not. pos~ible to ascertain
- the elevatiori -of' the -m~imum design water level: for the plant site.*.. The-most rec-ent. reference to, the m(;!Ximum. wa~er lev~~ -appears in Amendment: 15, response to.question* 2.4 which implies a maximum*.flood level of El.-?93.5 feet~.:.It is. apparent that* the appliccitlt has not made "any calculations *. _*
relevant to -the*.* eyalµat.ion of the surge in the southern basin of Lake
'Michigan a~sO'ci~teci with the Probable. Maximum meteorofog:i.cal.~ve,nt ~nd. its
. --gf_f~cJs on* the design and operation of.. the plant.* The only method.-presently ava:i,,labie by which' the'maximt.lm surge level may be derived is presented in
- a. paper entitled "The* Predict:t'on of 'Surges in' the Southern Bas*in.of Lake.*
- Michigan" by *G. W. Rlatman, S*. cM; Irish and L. A. Hughes; mop.thly Weath~r Review., Vol. ** 93; No. 5, May* f965-:
App.lying th~ method described in this *.
Peiper, *assuming a pressure rise of O. 2i inches (8 mb) and sh_oaling factor of*3.5, the resultant maximum surge height at the Palisades Plant is 13.6 feet *.. Combinip.g the surge with the maximum lake~ level (El.* 583.. 6* USC&GS
.
- DatuJD.) results-' in a maximum design water level *elevatio~ of 597. 2 feet above USC&GS.Datum.
Similar ca.1ci:i1atioris *per.formed for the;.. cDonald C. Cook Plant,. 23 miles southwest; resulteq in a maxiiiiµ1ll design*wai:er level elevation of* 594. 5 feet USC&GS Datuin.*

__ ;_:*' }{r. Roger S-. Boyd 30 October 1969 It should b_e recogni_zed that the applic'ation of this method of surge predicition is based on intuitive judgment.
The relative close proximity of the D. C. Cook*Plant was considered in the final evaluation of the design water level. It:is therefore the opinion of this office that_ the maximum:
design water level for the Palisades Plant should be established at no less than El. 594. 5_ feet USC&GS Datum but preferably recommended ai: E*l. 597. 2 feet USC&GS Datum.
