1.2 CHEMICAL DISCHARGE LIMITS Objective:

To insure that all chemical releases from the station are controlled and diluted so as to be non-toxic to aquatic organisms in Hartwell Reservoir.

Applicability:

Applies to release of chemical effluents from the station.

Specification: A. Chemical wastes and the resulting chemical concentra-tions in the Keowee River shall not exceed the maximum concentrations given in Table 1.2-1 " Chemical Wastes from Oconee Station."

3. All water discharged from the wastewater collection basin shall have a pH between 6.0 and 9.0.

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

Monitoring: A. The pH and specific conductance of the wastewater col-lection basin ef fluent shall be determined and recorded daily.

B. A chemical inventory system shall be maintained to show the quantities used for each chemical in Table 1,2-1 and for any other environmentally significant chemicals which may be used. A combination of purchasing records and physical inventories shall be used to determine chemical usage.

Bases:

Continuous dilution of the station chemical discharges will assure that concentrations of chemical effluents are  !

maintained at low values. Table 1.2-1 is the same as l Table III-14 in the Oconee 1, 2, and 3 Final Environmental S tatement.

Requiring that the effluents result in chemical concentrations which are not toxic assures that aquatic organisms are protected.

Records of chemical usage plus sampling of effluent wastewater are used to monitor the quantity and strength )

of chemicals discharged,  ;
