1 Appendix 1 - Influent and Effluent Monitoring Data for November 1988

I

OVERVIEW (3'.

During the month of November, discharges occurred from Discharge Paths 001 (once through cooling water),

001A, 001B, 001D, 001E,

001F, 001G, 001H, 001J, 001L, 001N, 001P, and 002 through 013.

No discharges occurred form Discharge Paths 001C, 001I, 001K, and 001M.

B.

C.

The annual analysis for arsenic in a composite sample of Discharges

001B, D, F, H, I, and L was performed in October 1988.

Due to the length of the analysis, the result was not included in the report for October.

Therefore, the result has been included in this report and can be found in Appendix l.

On November 8, 1988, effluent samples of the Domestic Sanitary Waste System, Discharge 001N, indicated that the limits for oil and grease, non-filterable residue and settleable solids had been exceeded.

The concentration of these parameters increased due to an increase in the blanket depth in the react tank.

Adjustments in the frequency of solids removal from the react tank were made to lower the blanket depth.

An increase in filamentous growth was not associated with the current condition of the system.

Analysis results on November 19, 1988, indicate that the system parameters returned to within the limits.

The anaysis results for each effluent parameter for the month of

November, along with the parameter l.imits, are listed below:

November Data for Discharge 001N Date 11/01/88 11/08/88*

• two samples taken during different portions of decant cycle Parameter

~Nhi A

~Oil Oil 5 Grease NFR SS 15 mg/1 60 mg/1 1.0 mg/1 20 mg/1 3.0 mg/1 D.

In all cases, chemical, radiochemical, and toxicity analyses were performed in accordance with chemical analysis procedures contained in the Diablo Canyon Power Plant, Units 1 and 2

Plant Manual, Volume 8, by State approved laboratories, or laboratories meeting the requirements specified in the California Regional Water guality Control Board Central Coast Region "Standard Provisions and Reporting Requirements" dated January 25, 1985.

Receiving water monitoring was performed in accordance with approved biological and oceanographic procedures.

SUMMARY

OF MONITORING PROGRAM A.

Monitorin of Plant Influent and Effluent 1.

2.

The results of the November plant influent and effluent monitoring are reported in Appendix 1.

I' static bioassay of Discharge 001 is performed quarterly in January, April, July, and October.

B.

Monitor in of Receivin Waters Ecolo ical Studies at Diablo Can on 2.

Ecological studies in the vicinity of Diablo Cove, referred to as the Diablo Canyon Marine Environmental Monitoring Program (MEM), continue.

Sediment Anal sis 3.

Sediment samples were collected and analysis reported in September.

Aerial Photo ra h

of Kel Beds Aerial photography (infrared film type 2443) of kelp beds in the vicinity of Diablo Canyon is required in February,

June, and October.

4 ~

Surface Water Tem erature 5.

Surface water temperatures are mapped every other month.

Stratified Water Tem eratures Stratified water temperatures are measured in February,

June, and October.

6.

H and Dissolved Ox en of Receivin Waters 7.

Sampling of pH and dissolved oxygen is scheduled in February,

June, and October.

Incident Li ht Measurements 8.

Incident light measurements are reported quarterly in reports submitted in March, June, September, and December.

In situ Bioassa Results of the Mussel Watch program will be reported to the Board directly from the California Department of Fish and Game in their periodic report for this program.
