Dear Mr. O'Reilly:
In reference to your letters of August 12, 1980 and June 24, 1980, and our letter dated July 18, 1980, Serial Number 585, regarding an apparent item of non-compliance reported in IE Report Numbers 50-338/80-25 and 50-339/80-26, we are forwarding the attached supplemental response.
Although previous corrective action was taken, we still recommend that the infraction be deleted or changed to an open item and we support that recommen-dation with Attachment 2 which corroborates our view.
Very ruly yours, k
B. R.

Dear Mr. Hopper:
In the attached table are our results of stable iodide content in VEPCO nilks from February 1979 through June 1980. The pre-June 1980 samples have concentrations between < 0.03 (listed as 0.0) and 0.77 mg/ liter while the June 1980 values were between 0.56 and 0.81.
In the forper case there are 46 resuits; in the latter, only three.
Since there are only three results representing no addition of fomhldehyde I believe it is too early to draw a conclusion, especially since there are a few formaldehyde results in the range of the June 1980 results.
My interpretation of the Health Physics article by Montgomery and Gibson is that there can be a protein-bound iodine problem with milk samples using formaldehyde but that the data in the article is insufficient, even by the admission of the authors, to extrapolate the results to a generalization of the issue.
For example, according to the article the temperature of the milk at the time of the addition of formaldehyde can have a significant affect on the protein-binding.
The authors also admit that milk from other areas of the country (as opposed to the Cincinnati, Ohio area)..."may differ in oxidase activity, stable iodide concentration and other constituents that could affect protein hinding of formaldehyde-preserved milk".
Therefore as I mentioned in the first paragraph that I would consider it too soon after the change of the sample collection procedure of not adding formal-dehyde to pass judgement on this issue.
Sincerely, 0, AM 75@
