- 3201 Gentlemen:
At a part of the processing of the State Permit for the claiborne Enrichment Center near Homer, Louisiana, we have been in contact with Phil Hammond of Duke Engineering concerning certain details of the receiving water, Bluegill Pond.
In conversation with Mr.
Hammond on October 18, 1992, we requested the following information and he asked us to put this request in letter form to you.
1.
As a part of the evaluation of the Pond as a receiving stream, we need information on the physical configuration of the Pond.
A scale drawing of the Pond, showing depths or contours, would be suitable for our calculations.
Volonstric calculations i
would also be very helpful.
Please mart ae position of the outfall on the drawing.
2.
We understand that Duke Engineering is takino quarterly field water quality readings of conductance, pH, temperature, dissolved oxygen, and alkalinity on Lake Avalyn.
We request a copy of that data, both past and future (through June 1993),
to be used as an aid in assessing the characteristics of the l
receiving water.
l 3.
Our permit considerations include computations involving hardness and TSS characteristics.
There are no hardness or TSS data available for the receiving water or for nearby and similar waters.
We therefore request that samples for hardness and TSS be taken at Bluegill Pond (vicinity of the outfall) on a twice a month basis, beginning as soon as possible, and that the results of the analysis of those samples be provided to DEQ.
Max Forbes, of our Engineering Section, discussed with Mr. Hammond the taking of quarterly samples; we now feel that a hardness and TSS data base of suf ficient size (about 10 determinations of each) to permit 15 percent 11es of these characteristics must be developed as soon as possible, and that more frequent sampling is therefore i
called for.
4.
Discussion with the permit writer assigned reveala a concern on your part that concentrations of sulf ate in the groundwater supply could cause concentrations of that elemer.t in your effluent to be above the permissable level. To properly l

document the natural sulfate condition, we request that available data on sulfate in the groundwater supply be provided to the Ground Water Protection Division of DEQ; the address is : La. Dept. of Environmental Quality, GWPD, P.O.
Box 82215, Baton Rouge, La. 70884-2215.
If sufficient data to provide a reasonable picture of sulf ate concentrations are not available, we would suggest a sampling program to establish a data base; that data should also be provided to DEQ.
In paragraph 3 above, we requested that data on hardness and TSS be gathered for Bluegill Pond. Since sulfate may also be a concern in the receiving water, we request that sampling for sulfate in Bluegill Pond be done with the sampling for hardness and TSS; this will provide a background for further e
considerations.
5.
Representatives of DEQ are likely to be in the Home crea before December; we request your permission to visit BO;6J ll i
Pond and Lake Avalyn to take one set of sulf ate, hardness, and TSS samples. If permission is granted, please furnish contact information for a local (Homer area) representative of L.E.S.-
L.P..
We appreciate your cooperation in responding to these requests; this information wil] expedite the processing of the permit.
If you have questions on any of the requests, please contact Cheryl LeJeune at 504-765-0525.
Sincerely, t
