ATTACHMENT TO LICENSE AMENDMENTS AMENDMENT NO. 40 TO FACILITY OPERATING LICENSE NO. DPR-42 AMENDMENT N0. 34 TO FACILITY OPERATING LICENSE N0. DPR-60 DOCKET NOS. 50-282 AND 50-306 Revise Appendix B as follows:
Remove Page Insert Page B-6 B-6 1390 074
B-6 Soecification:
The cooling water system shall be chlorinated for not more than a total of 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> per day. During chlorination periods, the total residual chlorine concentration at the outfall of the circulating water vsystem shall not exceed 0.05 ppm.
If chlorine treatmen't of the cooling water system is 30 minutes or less per day, the total residual chlorine concentration at the outfall shall not exceed 0.1 ppm.
Corrective action will be taken if the protection condition is exceeded.
If chlorination of other systems is necessary, the same standards apply.*
l Basis:
The circulating water system condensers are cleaned mechanically.
Nor= ally only the cooling water system is chlorinated. The protection conditions of this specification will provide protection of the aquatic biota in the receiving waters.
2.4.2 Corrosion Inhibitors and pH Control Agents Objective:
To avoid a significant deterioration in the river's water quality, by limiting the discharge of certain chemicals from the plant.
Specification:
The amount of certain che=1cals discharged to the river shall not exceed the following cumulative annual amounts as follows:
ammonia 3,300 lb/yr.
hydrazine 2,800 lb/yr.
morpholine.
700 lb/yr.
cyclohexylamine These chemicals are discharged at the outfall.
No other corrosion inhibitors shall be discharged.
~4hile re=aining within the above annual limits, daily blevdown discharge may vary as operations require, but under no conditions exceed a saximum of 30 pounds per day of a=monia at the outfall, with proportionately lower amounts of the other chemicals specified above.
If the stated daily or annual protection conditions are exceeded, correc:ive action will be taken.
Basis:
The only release of corrosion-inhibitor chemicals in plant operation is from the all volatile water chemistry trea:=ent (AVT) required for the steam-generator secondary water treatment system.
During nor=al full power opera: ion, the steam generator blowdown ficw is normally saintained at 120 gpm (total for both units).
- A special chlorination treatment of the circulating water system, similar to that described in Exhibit C of the Licensee's amendment request letter dated October 30, 1979, is permissible for the purpose of destroying parasitic amoeba.
Th is treatment is to be completed by December 31, 1979.
