Subject:
Catawba Nuclear Station -NPDES Permit No. SC0004278 Sodium Bromide Request for Permanent Approval File: CN-702.13 1
Dear Mr. Eleazer:
)
This letter is being written to request that sodium bromide be approved u a permanent treatment compound for the control of algae in the cooling towers at Catawba Nuclear station. As you may recall, Catawba has been using this compound on a temporary basis in order to determine the effectiveness of its use. The use of sodium bromide will allow the station to reduce the total amount of treatment chemicals used.
In your letter dated September 15,1994, you stated that before sodium bromide can be used permanently as a maintenance chemical in the cooling towers, the NPDES permit will have to be modified to add Free Available Oxidant (FAO) to the permit.
We would like to propose that Free Available Chlorine (FAC) continue to be listed on the NPDES permit and that the permit not be modified until the next permit renewal. The actual -
analytic 6 method will be unchanged regardless of whether the analysis is reported as FAC or l
. FAO.
Both sodium hypochlorite and sodium bromide' are oxidants.
Since sodium l
hypochlorite has historically been the only oxidant used, FAC has been more appropriate to report. Regardless of whether you report FAC or FAO the results are the same. The station monitors this outfall to ensure that the discharge is below permit limits prior to blowdown.
