Section I Technical Specification 2.0 ENVIRONMENTAL PROTECTION CONDITION I-l l

2.0 ENVIRONMENTAL PROTECTION CONDITION Requirements of 2.3 (Chemical Analyses and Chemical Use Report) have been met as demonstrated by Table 1, and the following summary.

2.3 Chemical Chemical Analyses River watet samples were collected by plant personnel and analyzed monthly from January through December at the river water intake structure and the discharge canal of Cooper Nuclear Station.

Analyses for turbidity, specific conductance, chlorine, copper, iron, potassium, sodium, and pH were conducted by plant personnel as specified in the Cooper Nuclear Station Environmental Technical Specifications (ETS). Turbidity and specific conductance values in the discharge canal were within the ETS limitations of less than 10% greater than the inlet values.

Total chlorine concentration in the discharge canal was less than 0.02 mg/l and, therefore, did not exceed the ETS maximum criterion of 0.1 mg/1.

Concentrations of copper, iron, potassium, and sodium in the discharge canal did not indicate any substantial increase due to plant operation.

The analyses for pH at the inlet and the discharge canal were well within the ETS limitations of 6.5 to 9.0 pH.

1-2

The limitations of the above mentioned parameters were not exceeded; therefore, there has not been any significant chemical effect on the Missouri River water due to station operation in 1981.

4.0 ENVIRONMENTAL SURVEILLANCE AND SPECIAL STUDIES Requirements of 4.1.1.2 (Plant Cooling Water Systems Fish Entrapment) have been met as demonstrated by Tables 1-4 and the following summary.

4.1.1.2 Plant Cooling Water Systems Fish Entrapment Limits Samples of fish impinged on the traveling screens were collected in accordance with the Environmental Technical Specifications (ETS). Sampling was conducted hourly at least twice per month with the July, August, and September collections being performed during hours of darkness.

A total of 287 fish, representing 14 taxa, were collected during 29 hourly collection periods in 1981 (Table 1). >bnthly impingement rates ranged from 0 to 24 fish /hr. with higher rates coinciding with the occurrence of young-of- ,

the-year gizzard shad and freshwater drum.

The most common species impinged were gizzard shad, freshwater drum, river carpsucker, and carp which collectively comprised 91.6% of the total. Game fish including sauger, white bass, white crappie, catfish, and bluegill comprised only 2.4% of the fish impinged. Species composition and relative abundance of fish impinged in 1981 were similar to those in previous years (Table 2).

As in previous years, diurnal rates were lower than nocturnal rates (Table 3).

Peak impingement of 54 fish /hr. occurred during a nocturnal sampling period in August. This rate was below the 90 fish /hr. limit established by the ETS.

II-2

Fish impinged on the traveling screens at Cooper Nuclear Station are returned to the river via a continuous wash system. Of the fish impinged during 1981, 45.3% were classified as alive and active (Table 4) and might have survived the impingement process.
