Permit (C04876), NPDES Permit CT0003263, dated December 14,1992.                                 ,
Dear Mr. Grier Millstone Nuclear Power Station l
Modification Request - CT0003263 Hydrazine and Coolina Water Flows On May 7,1996 representatives of Northeast Nuclear Energy Company (NNECO) and Northeast Utilities Service Company (NUSCO) met with you to discuss the need for modifications to NNECO's Millstone                ;
                                                                                                                    ~
Station NPDES Permit, Reference. Pursuant to those discussions NNECO herein requests that Permit CT0003263 be modified as follows:
Hydrazine - DSNs 001B6. 001B9. 001C4. 001C6. 001C6 M. 001C9. 001B. and 001 C:
The current NPDES Permit, Reference, allows hydrazine discharge for Discharge Serial Numbers (DSNs) 001B9, 001C4 , 001C6, 001C6(b), and 001C9. Each DSN has a discharge concentration limit (mg/l) which is monitored (up pipe) before discharge to the quarry through its respective unit cooling discharge      ,
pipe, DSN 001B and 001C. When calculated with individual flows, the permit authorizes a daily total l    discharge of 76 kilograms (kg) of hydrazine to the environmental.
The Millstone Station Chemistry Department has determined that the Condensate Polisher Regeneration Sumps of Units II and III are a source of hydrazine not specifically defined in the permit. Therefore,
,    NNECO is proposing these additional sources be identified and authorized for hydrazine discharge.
However, NNECO is not proposing an additional quantity of hydrazine be authorized, rather that by shifting control to the end of pipe (establish a mass limit for hydrazine at DSNs 001B and 001C only) the i
total permitted amount of hydrazine discharged can actually be reduced from 76 kg/ day to 65 kg/ day. A procedure to accomplish this through internal controls has been drafted and is included in Attachment A.

Therefore, NNECO is requesting that Permit CT0003263 be modified identifying DSN 001B6 as a source                   i i
Sf hydrazine and that the discharge of hydrazine be permitted as follows:
D.SE          Max Concentration / Batch     Max Quantitv/Dav*                                              .

* Maximum quantity per day from DSNs 001B6,001B9,001C4,001C6,001C6(b),
and 001C(9).
i                        " When discharging, two unit circulating water pumps must,be running.
1 In order to further minimize the discharge of hydrazine DSNs 001B1(a) and 001B8 will not discharge whenever DSNs 001B6 and 001B9 are discharging, and DSNs 001C4,001C6,001C6(b), and 001C9 will                          ,
'              not discharge whenever DSNs 001Cl(a) & 001C8 are discharging. DSNs 001B1(a),001B8,001Cl(a),
;              and 001C8 are specified to discharge on a frequency of only two to five times a year and therefore not pan of this modification request.
l l
Condenser Cooline Water Flows - DSNs 001 A. 001B. and 001C:
When the present NPDES permit was written in December 1992, the flows were changed from " average"                    ;
to " maximum," however, the average flow values from the former NPDES permit were inadvertently used                  l as maximum flows in the present permit. NNECO requests that the flows be changed to the following; 001A           680,000,000 gallons per day                                                          .
001B           870,000,000 gallons per day                                                          !
001C         1,400,000,000 gallons per day l
Enclosed is a completed Permit Application Form, a check in the amount of $500.00, and revised pages 1               .
and 2 of Attachment O for DSN's 001 A,001B, and 001C with the new flow rates.
l l              As discussed at the May 7,1996 meeting, the modification to the cooling water flows requires NNECO to                I give public notice ofits intent to modify the permit. Enclosed is a copy of the notice to be placed in the New London Dav. A cenified copy of the notice will be sent to you following its publication.                          l I

1.1   Objective l                    Provide instructions for managing NPDES discharges that contain bydrarine for the purpose of ensuring NPDES permit compliance.
1.2 Discussion NPDES limits have been established for hydrazine at the end of the pipe for Unit 2 cooling water discharge (DSN 001B). Because hydrazine may be discharged from up to 2 up-pipe independent sources, a discharge control program is required. NPDES monitoring is performed and j                   controlled by the Millstone Station Chemistry Department.
This procedure does not address the infrequent hydrazine discharges related to steam generator secondary side wet layup drainage discharge 2
(DSN 001B-1(a)) and condenser hotwell discharges (DSN 001B-8) 4 other than to prevent discharges of hydrazine from other up-pipe sources
;                    during these discharges.
l                    A permit system similar to that used for controlling radioactive discharge i is used to control hydrazine discharges. For each planned hydrazine discharge, the total hydrazine content (mass) is conservatively determined.
An evaluation is then made to determine if the planned discharge is within the daily hydrazine loading allotted for Unit 2. If the hydrazine loading
;                    from the planned discharge is within the limitation, Chemistry Supervision
<                    will authorize the discharge. NO HYDRAZINE DISCHARGE CAN TAKE
;                    PIACE WITHOUT CHEMISTRY DEPARTMENT AUTHORIZATION.
:                    Tb avoid Operations or Maintenance Department scheduling delays, work schedules involving hydrazine discharges should be communicated to Chemistry wellin advance of required discharges.

1.1 l
Provide instructions for managing NPDES discharges that contain                   i hydrazine for the purpose of ensuring NPDES permit compliance.
1.2 Discussion NPDES limits have been established for hydrazine at the end of the pipe for Unit 3 cooling water discharge (DSN 001C). Because hydrazine may be discharged from up to 4 up-pipe independent sources, a discharge               l control program is required. NPDES monitoring is performed and                    (
controlled by the Millstone Station Chemistry Department.
This procedure does not address the infrequent hydrazine discharges related to steam generator secondary side wet layup drainage discharge (DSN 001C-1(a)) and condenser hotwell discharges (DSN 001C-8) other than to prevent discharges of hydrazine from other up-pipe sources during these discharges.
j A permit system similar to that used for controlling radioactive discharges is used to control hydrazine discharges. For each planned hydrazine discharge, the total hydrazine content (mass) is conservatively determined.
An evaluation is then made to determine if the planned discharge is within        )
l the daily hydrazine loading allotted for Unit 3. If the hydrazine loading         !
l                                               from the planned discharge is within the limitation, Chemistry Supervision will authorize the discharge. NO HYDRAZINE DISCHARGE CAN TAKE PLACE WITHOUT CHEMISTRY DEPARTMENT AUTHORIZATION.                                 I Tb avoid Operations or Maintenance Department scheduling delays, work schedules involving hydrazine discharges should be communicated to                )
l                                               Chemistry well in advance of required discharges.
