B. F. Bees J. Mavidian R. T. Eeutes I. Spieklee D. Anderson Boston and McLemore of GAI started the meeting by reviewing the PSAR meterial.
Photographe of the 19% flaed were presented. A large plaa map of the Three-Mile Island vicinity see presented. The nep had 1936 53Gs measurements, other 1936 messersemats, 1964 messerseesta, and design flood computations. GAI described the esiculational methods. sees differences in reference data between 53GS and GAI were
. z - :f. SAI had isopisthe constructed acrees the a==W depicting tha coreputer predictise of the 1936 flood. The predic-tiene estandad free the Terk Eevee Bas, louer part, above Three-Mile Island to the upper and of Bill Island. Fredictises were ~295 feet at the laser end of Three-Mile Island to ~ 297 feet at the apper end.
The modified GAI emie=1stimme new show fairly good es-emeest with Escs measure-meats at the west shore (Goldsboro) directly opposite the middle of Three-Mile Island. Photographs takaa (and left with BEL) at the messerement point on the afternoon of March 19, 1936, verify the deemesated numbers very well. Two measur====e= en the east shore above Three-Mile Island toad to verify the pre-dictione. Bowever, Meyer had a point (sepublished) indicating 3 feet in escass of the GAI observaties, and 2 feet in excese of prediction. Be real difference is ---a :::f, des to the tahmeest errer la these type of calemistions.
GAI stated their salculatimmal methods correlated well with the 1964 fleed.
GAI them presented a separate may em the design flood samputations. The new' dika elevaties is 307 feet. unter elevation around the upper and of Three-Mile Island is 303-304 feet. The assoas height (3-4 feet) is for wave actise.
Flaat elevetime is 304 feet. Four feet of freeboard is considered a require-meat for wave action.
BEL and cassultants --=d.
Relative merits of asking for more computations was considered. We them asse the applicant two choices:

4 Roger S, Eoyd Nove:nber 27, 1967 1.
Calculate water dilferentials due to the bend in the river that mi;ht have caused height differential, er 2.
Raise the dike 2 feet (in wave-action areas).
The applicant stated that he favored No. 2.
We also notified ;.he '.pplicent that the periaanent access bridge to the island must terrr.in open during the design flood.
The applicant may subsequently recalaulate and request a lowering of the dike due to iaproved calculations.
