2.2.2 Discharge Velocity Not Applicabic.

2.2.3 Flow Rate Restrictions Not Applicabic.

2.2.4 Reservoir Drawdown Not Applicable.

2.3 Chemical Objective To protect the local biota from lethal and sublethal effects of chemical discharges. To assure that the most sensitive use of the receiving mediun by human populations is protected. To minimize degradation of the quality of the receiving medium.

Specification All plant chemical discharges except that from the plant sanitary system shall be diluted by the plant circulating water during release to assure that the stated objective can be achieved.

Monitoring Requirements Sampling will be done in accordance with National Pollutant Discharge Permit No. AR0001392 as issued by the Environmental Protection Agency.

Results of sampling shall be submitted to the Nuclear Regulatory Commission concurrent with submittal to the Environmental Protection Agency, s

in 2.4 Radioactive Discharge

. 0bjective To define the limits and conditions for the controlled release of radioactive effluents on the environs to ensure that these rsleases are as low as practicable. These releases should not result in radiation exposures in unrestricted areas greater than a few percent of natural. background exposure. The release rate for all effluent discharges should be within the limits specified in 10 CFR Part 20.

To assure that the release of radioactive material to unrestricted areas

' meet the as-low-as-practicablo concept, the following objectives apply:

For liquid wastes:

a. The annual total ~ quantity of radioactive materials in 11iquid waste, excluding tritium and dissolved gases, should not exceed 5 curies;

~

b. . The annual average concentration of radioactive materials in liquid waste upon release from the Restricted Area, excluding tritium and dissolved noble gases, shall not exceed 2 x 10-8 pCi/ml; and

c. The annual average concentration of dissolved gases in liquid wgste, pCi/ml.

upon release from the Restricted Area, shall not exceed 2 x 10-For gaseous wastes:

a. Averaged over a yearly interval, the release rate of noble gases and other radioactive isotopes, except.I-131~and particulate radio-isotopes,with half-lives greater than eight days, discharged from the plant should result in a dose rate at the site boundary of less_ than .

10 mrem to the whole_ body or any organ'of an individual.

4-1 (Next h is 4-6) 4.0 . ENVIRONMENTAL SURVEILLANCE

, The surveillance program provides an examination of the aquatic eco-system of Lake Dardanelle -in the vicinity of the plant as well as providing information on air, precipitation, ground water, soil, vege-tation and milk by radiological analysis of samples in the area of the plant.

Since the aquatic ecosystem is the most likely to be affected both chemically and radiologically by plant operation, more emphasis has been placed on its surveillance. The waters of Lake Dardanelle are subjected to frequent chemical and radiological analyses. Organisms that live in the lake are studied biologically and subjected to radiological testing. Studies are also made on the effects of impingement and entrainment of organisms in the cooling water system.

Provision is also made for temperature monitoring and controlling the rate of change in water temperature (Specification 2.1.4).

Results of the program, in,cluding the reports submitted in accordance with Specification S.6, will be reviewed as specified in S.3.

. (1) h'ater Quality Objectives:

To determine effects of plant operation on the physical and chemical parameters at selected points covered in the pre-operational background surveys.

Specification:

(a) Monthly samples will be taken at points shown on Figure 4-3 and subjected to chemical tests listed in Table 4-5.

(b) Physical measurements listed in Table 4-4 will be made monthly.

Reporting Requirements:

These measurements are made by personnel of the University of Arkansas at Little Rock and results will be reported in the Semiannual Report of the UALR Project and will be included in reports filed under Specification 5.6.1.

Bases:

This program is essentially a continuation of the Dardanelle Background Survey begun by the University of Arkansas at Little Rock in 1968.

(2). Thermal Measurements Objective

To determine the effects of plant operation on the temperature

'of the Reservoir in those areas most likely to be affected.

Specification:

(a) Monthly sampics shall be taken at points shown in Table 4-3.

(b) Sampics shall be taken at one, two, five, and seven feet below the surface, and at five-foot intervals from that point to the bottom elevations.

-(c) Readings shall be made with an approved multi-thermister measuring probe and instrument.

Reporting Requirements:

Same as " Water Quality" above.

Bases:

Same as " Water Quality" above.

(1) General Ecological Survey Obj ective:

The purpose of this survey is to provide information on the compatability of Arkansas Nuclear One (ANO) with the planktonic, nektonic, and benthic populations of the Dardanelle Reservoir.

Preoperational' monitoring- studies have been conducted since

1968, approximately five years prior to operation of Unit 1.
