Appendix 3 - Incident Light Measurements - Fourth quarter. 1987

OVERVIEW

A. During the month of December, discharges occurred from DischargePaths 001 (once through cooling water), 001B, 001D, 001E, 001F,001G, 001H, 001J, 001L, 001N, 001P, and 002 through 013. Nodischarges occurred from Discharge Paths 001A, 001C, 001I, 001K,and 001M.

B. In all cases, chemical, radiochemical, and toxicity analyses wereperformed in accordance with chemical analysis procedurescontained in the Diablo Canyon Power Plant, Units 1 and 2 PlantManual, Volume 8, by State approved laboratories, or laboratoriesmeeting the requirements specified in the California RegionalWater guality Control Board Central Coast Region "StandardProvisions and Reporting Requirements" dated January 25, 1985.Receiving water monitoring was performed in accordance withapproved biological and oceanographic procedures.

SUMMARY OF MONITORING PROGRAM

A. Monitoring of Plant Influent and Effluent

1. Results of monitoring of plant influent and effluent inDecember are reported in Appendix 1.

2. A static bioassay of Discharge 001 is performed in January,April, July, and October.

B. Monitoring of Receivi~n Waters

l. ~Ei 1R i i 1 C

Ecological studies in accordance with the Thermal EffectsMonitoring Program (Provision D.4.a) continue.

2. Sediment Analysis

Sediment samples are collected in September.

3. ~A

Aerial photography (infrared film type 2443) of kelp beds inthe vicinity of Diablo Canyon is required in February, June,and October.

4. Surface Water Temperature

7. Incident L~i ht Measurements

Incident light measurements for the fourth quarter of 1987 arereported in Appendix 3.

8. In situ Bioassay

Results of the Mussel Watch program will be reported to theBoard directly from the California Department of Fish and Game

in their periodic report for this program.

APPENDIX 2

Surface Seawater TemperaturesDecember 21, 1987

.Surface water temperatures were measured on December 21,

1987 between 1405 and 1528 PST. A towable electronic

bathythermograph (TOWED-BT) was used for thermal plume mapping.

The TOWED-BT is a self-contained underwater unit. The TOWED-BT

uses a platinum resistance, pressure independent temperature

sensor. The sensor has a response time of 0.25 seconds, with an

accuracy of + 0.1'F (0.05'C). An oil filled strain gauge

pressure transducer accurate to 0.3Z (full scale) is used to

determine depth of the instrument (TSK, 1985). Temperature and

depth data are collected at f.ve-second intervals. All data are

recorded in internal IC memory. Data were retrieved after the

test using a photomagnetic coupler and microcomputer.

The positions during the thermal plume mapping were

determined with a Motorola MiniRanger III system. The MiniRanger

III system is a range-range navigation system, with an accuracy

of + 0.5 m when used with a data processor.

Intake and discharge temperatures were measured using Sea

Data TR-2 temperature recorders. The Sea Data units have a

manufacturer's specified accuracy of + 0.2'F (0.1'C) with a

response time of two seconds (Sea Data, 1984). The temperature

sensor at the intake is located in intake conduit, behind the

circulating water pumps. The discharge temperatures are measured

on the center wall at the top of the discharge structure.

Offshore ambient temperature was defined as the lowest

temperature recorded during the thermal plume mapping.

Temperature and position data were merged and surface

isotherms, in degrees above the ambient temperature (AT), were

computer generated (Figure 1). Discharge volumes reported for

Units'1 and 2 are the circulating water pump volumes. The area

covered by each 2'F isotherm was calculated and is presented in

Table 1. When an isotherm is not completely enclosed within the

sampling boundary, the boundary is used as the limit in

determining the areal extent of the contour (White, 1986)., These

values, are within the range of isotherm areas reported by Tu et

al (1986).

Incident Light MeasurementsFourth quarter 1987

0INCIDENT LIGHT MEASUREMENTS

Incident light measurements are reported as micro-Einsteins per meter-squared per second of incident photosynthetically active radiation(PAR). Light is measured by photosensors at three underwater stationsand at a shore station. Light values are sampled synchronously everytwenty minutes subtidally, and every five minutes on land, andmagnetically recorded. Light values are corrected for individualcali'bration factors prior to reporting.

Values reported this quarter are similar to those reported the fourthquarter of 1986, except for the South Diablo Cove station in Decemberand the North Diablo Cove station in November where reduced values aredue to biofouling on the sensor probe.
