ANNUAL ENVIRONMENTAL MONITORING REPORT, 1981 SUPPLEMENT A post-submittal review of the Annual Environmental Monitoring Report, ANO-1 & 2, 1981 by the Safety Review Committee has identified several items that require clarification and/or explanation in the subject report.

1. The Environmental Technical Specification Table 4-3 states that the Trawling Survey will have "2 samples in each area every other week l March, April, May, June". One page 41, item number 3 in the report indicates that sampling began on March 27, 1981. This is generally true for most years of the program. The rationale for this apparent deviation from Appendix "B" specifications follows:

The fishery survey of the reservoir was designed to characterize the fishery in the reservoir and aid in the assessment of the impact on the reservoir due to the operation of ANO. Since this was the first study of its kind for the reservoir, sampling times were widely bracketed to ensure complete data for each type of sampling gear.

The meter net is a trawl used early in the year to detect spawning activity.

The first two years of sampling with the meter r.. indicated that no significant spawning activity took place in the first weeks of Match. Subsequent years of sampling confirmed this observation.

(See table below.) Sionificant spawning appears to begin in April,

reaching a peak from mid-April through May. Discussions with Arkansas Tech personnel, other environmental consultants and NRC staff revealed that the trawling survey could meet the intent of the survey by beginning meter netting in April. Therefore, meter net sampling was changed to weekly samples beginning the last week in March through July, weather permitting. However, no formal technical specification change has been submitted.

Since the objectives of the trawling survey are being met, we believe that the intent of this technical specification has been satisfied.

The technical specifications also require replicate samples be taken in each area for the trawling survey and the shoreline seine. All the tables in the report are a composite of the replicate samples in each area. Procedures for sampling are itemized beginning on page 42 of the report and the reader is referred to these pages for sampling specifics.

Meter net sampling results for the first two sample dates from 1974 through 1981. Areas and replicate samples are composited into one total sample per date.

2. The complete date on which monthly water quality data were collected was not reported in Appendix I-IV of the Dardanelle Reservoir -

Illinois Bayou Embayment Survey, The day of sampling was inadvertently omitted in the title of the computer processed version of the data tables. Sampling in 1981 was performed on the following dates:

January 24 July 18 February 20 August 29 March 25 September 19 April 29 October 23 May 20 November 14 June 20 December 29 Corrections will be made to computer software so that the 1982 report will contain the complete date.

3. Water temperature data reported in the Dardanelle Reservoir -

Illinois Bayou Embayment Survey (Appendix I, Tables 8-19) indicate differences greater than 15*F existed between the ANO intake (Station 16) and discharge canal (Station 1).

ANO Unit I has three thermal Limiting Conditions for Operation (ETS Section 2.1). One LCO limits the maximum change in te:nperature across the condenser. Under normal operating conditions with four circulating water pumps in operation, a maximum differential temperature of 15 F is permitted. If one or two circulating water pumps is inoperable, the maximum differential temperature across the condenser is limited to 30 F. These limits are monitored and maintained using hourly measurements from the condenser inlet and discharge canal RTD's.

One objective of the Dardanelle Reservoir Survey is to define the horizontal and vertical area of thermal influence by ANO on the temperature of the reservoir. Temperature data are not collected simultaneously and at the appropriate locations to determine the differential accurately. In fact, measurements at the areas of the intake and discharge are often made hours apart, so they can only be used for estimating differences between the two locations and thus i

are not intended to monitor compliance with the 15 F AT '

specification.

4. ANO Unit 1 Environmental Technical Specification (Section 4.1.1.a.6(b)) requires that data on " local fishing conditions" be  !

collected monthly at each of the 18 sampling sites on Dardanelle Reservoir. These data are not presented in this report.

From the date of Environmental Technical Specification issuance to about 1974, reporting of " local fishing conditions" as a " physical" water quality parameter was attempted. Little useful data was collected and reported, however, because of the subjective .:ature of the specification. Observations could not be quantified and trending from year to year was impossible. The implied objective of the specification was later interpreted to be that of monitoring the effect of ANO on the fishery resource of the reservoir. This monitoring effort was then incorporated into the Arkansas Tech University Fishery Research Project, which was implemented in 1974.

5. In the report on Thermal Impact Evaluation after a scheduled ANO Unit 1 shutdown, a change in temperature of greater than 10 F is reported on January 2, 1981.

The discharge temperature at 2200 hours0.0255 days <br />0.611 hours <br />0.00364 weeks <br />8.371e-4 months <br /> on January 2, 1981, was 48.13 F, not 58.13 F as reported. At no hourly interval was the rate of change greater than 5*F as specified in ETS Section 2.1.4.

6. The following paragraphs should be added to page 456:

During 1981 there were two brief periods (six samples analyzed) in which the iodine-131 dose equivalent activity in the reactor coolant exceeded 1.0 pCi/g. These " spikes" were of short duration as the primary demineralizers were able to reduce the iodine concentration to normal levels.

In accordance with ANO-2 Technical Specification 3.4.8, these events were reported as Licensee Events Reports (LER)81-008 and 81-008 Rev. 1.

7. Minor typographical errors or omissions on pages 418, 425, 427, 446 and 448, and page 7 of Attachment 1 have been corrected and the pages attached.

8. The Table of Chemical Usage (page 451, attached) has been revised to include a " Total" column for comparison with Technical Specification limits given in Table 3.1.

I

9. Table 1 page 347 was inadvertently repeated on page 353.

10. On page 385 it is stated that, "ANO Unit 2 reached criticality in December 1978." This should be, "ANO Unit 2 reached criticality in September 1978."

11. On page 406 the sentence, "In comparison with 1980 data, no iodine-131 was detected in any milk samples collected in 1981."

should read, "No iodine-131 was detected in any milk samples collected in 1981."

MILK' ANIMAL SURVEY APRIL 14-15, 1981 In accordance with Environmental Technical Specification 4.2.10, a survey was conducted April 14-15, 1981 to determine the location of animals which produce milk for human consumption. Milk producing animals (milk cows) are divided into two categories defined'as:

1. Class A Dairies - Dairies in which milk is intended primarily for human consumption as Grade A milk.

2. Individual Milk Cows - Family cows in which the milk is intended primarily for home use.
