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, 1
