February 1, 1995 Mr. Edward Truskowski Radiation Safety Officer Cintichem, Inc.

P.O. Box 816 Tuxedo, New York 10987

Dear Mr. Truskowski:

I am writing to confirm the discussions we had yesterday and this morning regarding strontium-90 analyses of water discharged through the 001 outfall at the Cintichem site.

Paragraph V(A) (1) of the Order on Consent (amendment 4) requires that water from the retention pond (S-12) be sampled and analyzed for gamma emitters before the water is batch released to the 001 outfall. Under section 380-6.1(b) (2) of 6 NYCRR Part 380, Cintichem is required to evaluate the concentrations and quantities of r3dionuclides released to the environment.

Therefore, although it is not specified in the Order, Cintichem 4 must also analyze S-12 samples for strontium-90. Samples collected at 5-12 during any one period of continuous pumping may be composited for Sr-90 analysis. )

We also discussed compositing some S-12 samples that are taken before the batch releases from the retention pond.

However, the Department will not approve that at this time. The S-7 diversion was only recently made permanent, on January 23,  !

1995. Before that date, the water from S-7 diluted the water in the retention pond. It also may have masked variations in the Sr-90 concentration of the pond water. Therefore, we do not yet know the current concentration of Sr-90 at S-12, nor how that concentration varies over time. We need to evaluate such data l before deciding how many samples should be composited. ]

Cintichem should continue to analyze for Sr-90 the individual batch samples from S-12. We will discuss the possibility of compositing samples after the Department receives the Sr-90 results for February, if there is sufficient data from l that time period.

Please call me (518-457-2225) if you have any questions.
