RE: SECOND QUARTER 1990 REPORT EAST ROATCAP CREEK
Dear Mr. Clapton,
In response to your letter dated August 10, 1990. Item #1 in your
letter will be forth coming from Richard Mills on how the situation
of the waste disposal area will be handled.
On Item #2, I have reviewed the stream flow data that was submitted
as part of the East Roatcap Creek monitoring. After reviewing the
information, I find, that our method to estimate stream flow was of
a poor quality and didn't give us any useful information. 2 have
gone back 3 years and looked up what stream gauge data that we have
for stream monitoring point SW #6, which is a stream gauge
approximately 1/4 mile below the point that the lower East Roatcap
Creek sample is taken from and I have used this information and the
information that we had gathered at the time of the sampling and
updated the Roatcap Creek monitoring report. Please note at the
bottom of the monitoring sheet there will be a explanation of how
the information was derived, when we had no actual stream gauge
data. Enclosed will be a copy of the updated information.
If you have any questions or comments on this matter please feel
free to contact me at [phone].
