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 that time period.
Please call me (518-457-2225) if you have any questions.
Yours truly, i
