Sirs:
In accordance with our meeting of April l'0, 1980 at the U. S.
Geological Survey Offices in Reston, Virginia, it is my under-standing that the following maps will be prepared on behalf of the Atomic Safety and Licensing Board for the restart hearings for Three Mile Island Unit 1:
l.
A map of the area within a 20-mile radius of Three Mile Island, showing planimetric details, land use/
T
)
land cover, and concentric circles centered on TMI and spaced at 5-mile intervals, at a scale of 1:100,000.
2.
A map of the area within a 50-mile radius of Three Mile Island, showing planimetri details, land use/
land cover, and concentric circles centered on TMI and spaced at 10-mile intervals, at a scale of 1:250,000.
In regard to format, A.
For each of the two cases, the maps will be prepared as a mounted exhibit, 46 X 58 inches, with clear overlays of (1) population density (by census units) and (2) a point source diagram indicating prevailing wind directions at TMI.
B.
For each of the two cases, as a full-size duplicate of A, unmounted, on paper which can be folded or rolled, without overlays, for use by the parties.

d l 1 In addition, there will be prepared an 11-1/2 X 15 inch C.
version of the 20-mile zone map, at 1:250,000 scale, as described by Mr. Wray.
For use by the parties, we will need 30 copies of the maps in formats B and C.
We have no objection to, and in fact encourage, wide dissemination of these maps to the public by whatever means you feel is appropriate.
Please let me know if this interpreta-tion of our meeting agrees with yours.
In connection with the hearing process, it may be necessary to have someone from USGS to serve as an expert witness in describing l
how the maps are made, on what information they are based, their i
accuracy and timeliness, and so on.
It'is possible, in fact likely, that a written description of the maps along with a written affidavir from the responsible person at USGS may suffice.
- However, should the need arise, we would like to have someone from USGS prepared to attend the hearing when the maps are introduced as exhibits.
1 The main purpose of thest-map exhibits is to serve as a common frame of reference for the c7ard, parties, and public during tee upcoming TMI-l restart hearings, particularly in relation to the discussion of emergency planning.
The planimetric/ land use-land cover maps we examined appear to be ideal for this purpose in that a great deal of relevant information is presented in a
~
,~
readily visualized form, yet all of the information is derived from standard data bases of the Commonwealth of Pennsylvania's Department of Environmental Resources and the U. S. Department of the Interior's Geological Survey.
Consequently, it is our opinion that these maps provide a factual and totally objective representation of the area surrounding the Three Mile Island Nuclear Station.
Based on our discussion of the cartographic capabilities of the USGS, I am aware that many other types of in-formation, such as proposed evacuation routes, mass care facilities, and access control points, could also be displayed.
However, to l
avoid any appearance of subjective selection of information, we wish to limit the board's exhibits as we described above.
The meeting at USGS was extremely interesting and informative.
Again, I continue to be amazed at the sophisticated mapping capa-bilities displayed by USGS.
We look forward to receipt of the map exhibits for the TMI area, and we believe that these ma will make a substantial contribution in " setting the stage"psfor presentation of evidence in the hearings.
Ve truly yours, i
o Linda W. Little, Ph.D.
