Dear Larry:

1 ,

.l I want to thank you for agreeing to meet with myself and our contractor to discuss the technical aspects of setting up an Emergency Response Data System .{j

.i

.i (ERDS) with your facilities. As I explained in our conversation, the intent of I

] this effort overall is to provide us with a detailed understanding of the )'

q availability of the data we desire, the potential for transmitting the data to

  • us, and the hardware and software necessary for use to handle the data. For-d your information, I have enclosed three documents which describe: the person-A nel and reference material we need access to; a sample of our questions on the parameters; and our computer and telecommunications information needs. I m

.j We are attempting to make this data collection effort complete anough so that

j no subsequent trips to any site will be necessary and that we obtain sufficient 3 information to implement the system should we do so. Therefore, as discussed, f
i we will plan on arriving at your downtown corporate offices at 9
00 a.m. on

! December 2,1985 to obtain as much information as possible at that location. A 3 determination will be made while we are there as to whether or not travel to l

'j the sites is necessary. I l )

{ Should you have any concerns or question please call me at (301)492-4155.

Sincerely, i i

John B. Hickman

lij It is recognized that the key disciplines necessary to support El the ERDS survey will represent different departments and  ;

organizational relationships unique to each utility surveyed l i)i (e . g. , Corporate vs. Plant Site Engineering staff). It is j

3 believed that most of the appropriate personnel will be the j

?.j i same as those on the project teams for SPDS and Emergency l 1 Response Facility Data Acquisition System development.  !

l 1

!l The appropriate utility manager to coordinate the ERDS site

.l survey is likely to be the same individual who is responsible l j. for SPDS, RG1.97 or ERF upgrade programs. The approximate lj man-hours for each site survey are based on a 2 to 2b day .

Lj survey for a single unit site or a 2 unit site where both units are identical and a common Data Acquisition System has been installed at a common TSC or EOF.
