DOW RESPCUSE TO EMERGENCY PLAN QUESTIONS This memorandu.1 uill respond to questicns with respect to the Dow emergency plan, posed during the testimeny of W. L. Tisdale.
1.
fonduct of Plant-Wide Hypothetical With respect to the hypothetical problems regularly conducted by Dou as a test of its
)
energency plan, Mr. Tisdale testified that Dow has not considered it necessary to design a plant-wide hypothetical. During cross-examination, Mr. Tisdale promised to consider whether such a plant-wide hypothe-tical nicht be a " good idea" in light of the plan to construct a nuclear plant across the Tittabawassee River (Tr. 3180).
Dow believes that its continuing experiences with real problems and with the hypothe-tical tests conducted on parts of its emergency plan, demonstrate that its emer-gency plan will work, in whole as well as in part. Nevertheless, and although the conducting of a plant-wide hypothetical involves najor effort, if a construction permit is granted, Dow will conduct a plant-wide hypothetical which will test the overall operation cf its emergency plan in the event of a nuclear episode. The plant-wide hypothe-tical will be of the same nature as present unit and zone hypotheticals, involving tagging and the like, without actual plant-wide shut-I down.

2.
Effect of Fog On Emergency Plan Mr. Tisdale was acked.uring crosc-cramination whether evacuation migat not take somewhat longer than under nor?.al circumstances, if it were necessary during"an accidental vapor release reculting in fog" (Tr. 3182).
The kind of acbiden'-al vapor " fog" which occurs frcm time to time at the Dcw Midland plant, does not prncent any significant probl?m incorar an evacuation is concerned. Dow personnel are well trained in their assigriments, so that even im-paired vicibility would not present a significant roblem. However, to thic point the kinds of p' fog" involved,which in the paat have always been of small dimensions, have not significantly affected visibility. Moreover, a hypothetical test has been conducted using Navy smoke bombs (Tr. 3233) and real evacuations have been held during actual vapor releases without problem.
Nevertheless, if a construction permit is granted, Dow will ccnduct another " hypothetical" during an actual accidental vapor release, as a test of its emergency plan under such circumstances.
3 Time Required to Evacuat ',
Low Population Zone At Applicant's request, Dow has agreed to evacuate the entire Dow Midland plant upon a signal from the proposed nuclear plant.
d Upon inquiry by the Hearing Board, Mr. Tisdale said he would study and report whether evacu-ation of the low population zone alene would take less time than evacuation of the whole plant (estimated to take slightly over 45 minutes).
(Tr. 3125).
Dow believes that it could evacuate god of the low pcpulation zone to outside the low popu-lation boundary, in about fifteen minutes and the balance in about ten more minutes, for a o
