l. EPA Comments In addition to general comments, which do not require a response, EPA had a specific comment on hydrology.

As indicated earlier to Mr. Regan, a brief response on this should be obtained from the Site Branch.

2. Interior No Interior comments have been received to date.

i

3. Commerce Commerce commented on meteorological assumptions used in the accident analysis.

We suggest the following response be in-cluded in Section XII.

"A comment was made that X/Q values and their probabilities should be provided.

The meteorological conditions used in the analysis approximate the dispersion conditions which would prevail at least 50% of the time at a typical site.

The value used for a short duration release at 610 meters agrees with the applicants value.

However, use of alternative meteorological assumptions, such as indicated in the Department of Commerce comment, does not significantly affect the overall environmental risk."
