1.2 CllEMICAL DISCHARGE LIMITS- I'!y,0fl hCC335 ;#9 ,

Objective

$$NQ To insure that all chemical releases from the station are controlled so as to be nontoxic to aquat,1c organisms and non-deleterious to downstream water quality in Hartwell Reservoir.

Applicability Applies to release of chemical effluents from the station.

Specification A. Limits for chemical wastes released from the Waste Water Treatment System and the Low Level Radwaste System shall not exceed the concen-

~

trations indicated in Table 1.2-1, " Monitoring of Chemical Wastes fror.

Oconee Nuclear Station."

B. Chlorine or other chemical biocides will not be used for condenser cleaning.

Monitoring The pH, specific conductivity, and concentrations of chemicals to be released from the station shall be monitored as specified in Table 1.2-1.

Reporting Requirements In the event any of the above specified limits are exceeded, a report shall be made within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> by telephone to the Director of the Regional Regu-latory Operations Office, followed by a written report within one week to the Director of the Regional Inspection and Enforcement Office (cc to Director of Nuclear Reactor Regulation).

The written report and to the extent possible, the preliminary telephone report, will:

(a) describe, analyze and evaluate the occurrence, including extent and magnitude of the impact, (b) describe the cause of the occurrence, and (c) indicate the corrective action (including any significant changes made in procedure) taken to preclude repetition of the occurrence and to prevent similar occurrences involving similar components or systems.

Bases The chemical monitoring and effluent limits specified in Table 1.2-1 will assure that concentrations of chemical effluents are maintained at levels that will provide adequate protection of aquatic and downstream water quality.

The limits specified in Table 1.2-1 are consistent with NPDES regulations (l),

State Water Quality Standards (2) Public Drinking Water Standards (3), and published toxicity data (4).

Monitoring is performed on a weekly frequency from a composite sample obtained
