Mr. James M. Moore, !!!
Alabama Department of Environmental Management I

Dear Mr. Moore:
/
t On October 28, 1986 approval was ranted to Alabama Power j
Company,inaccordancewith$ection423.13(te(2)ofEPA'sSteamElectric
)
Effluent Guidelines as well as the ***footn on page I-lb of the above i
referenced permit to conduct an extended service water chlorination study.
This study was nec,essary to determine what additional measures were needed to provide an adequate macroinvertebrate control program.
The object of this study was to determine the minimum combined chlorine concentration and t
exposure time necessary for macroinvertebrate control.
The Nuclear Regulatory Commission (NRC) has documen(Corbicula)h various reports ted throug I
and bulletins their concern with flow blockage of cooling water for various components (i.e., license holders must demon) strate the use of a program safety related equipment. As a result of NRC's concerns I
and requirements i
adequately control items such as biofouling within their facility.
Per the approval given to conduct the chlorination study, attached i
is a report which assesses the minimum level of chlorination possible for I
Corbicula control. We request you review the enclosed report, which
{
demonstrates the need for additional treatment in order to provide adequate control of the macroinvertebrate problem which could result in fouling in the service water system at Farley Nuclear Plant.
Based on the study results Corbiculacontrolwe request approval to chlorinate the service water system for j
provided for in the(in accordance with the conclusions of the report) as l
above referenced EPA and ADEM regulations and conditions. This program will be conducted as follows:
1.
The servvce water system chlorination program will be initiated annually, beginning May 1 or upon initiation of tre Corbicula's spring spawn (whichever occurs first) and continue through December 31.
2.
Each chlorination period will last for eight weeks or until greater than 90% mortality is reached (whichever occurs first) in indicator organisms.
e Mr. James M. Moore, III Page 2 April 15, 1988 3.
Chlorine concentrations will be maintained such that at least 0.20 mg/l free available chlorine is present at the main discharge surge tank, while not exceeding 0.2 mg/l total residual chlorine at the river discharge structure.
4.
Each unit will be chlorinated at a nominal frequency of eight weeks between the end of one treatment and the start of the next treatment.
5.
During chlorination of a unit's service water system for Corbicula control, the opposite unit will be treated with the existing chlorination program of three intermittent treatments per day to control microfouling.
We are requesting temporary approval to perform the above chlorination treatment program until your office has reviewed the report and an agreement is reached on a permanent chlorination program.
Monitoring will be performed as previously approved per the November (87)-
January (88) chlorination of Unit 1.
We would appreciate your timely notification of this approval, since the arrival of the 1988 spring spawning season will necessitate initiation of a control program in the near future.
Should you have any questions, please contact Mr. Mike Godfrey at 250-4194.
l' Sincerely,,
A0r
