l CALIFORNIA REGIONAL WATER QUALITY CONTROL BOARD SAN DIEGO REGION NPDES NO. CA0001228 MONITORING AND REPORTING PROGRAM No.88-001 FOR SOUTHERN CALIFORNIA EDISON COMPANY SAN ONOFRE NUCLEAR GENERATING STATION, UNIT 1 SAN DIEGO COUNTY A. MONITORING PROVISIONS

1. Samples and measurements taken as required herein shall bw represen-tative of the volume and nature of the monitored discharge. All samples shall be taken at the monitoring points specified in this Order and, unless otherwise specified, before the effluent joins or is diluted by any other vaste stream, body of water, or substance.

Monitoring points shall not he changed without notification to and the approval of the Executive Officer.

2. Appropriate flow measurement devices and methods consistent with accepted scientific practices shall be selected and used to ensure the accuracy and reliability of measurements of the volume of monitored discharges. The devices shall be installed, calibrated and maintained to ensure that the accuracy of the measurements are 1 consistent with the accepted capability of that type of device. i Devices selected shall be capable of seasuring flows with a maximum deviation of less than 25 percent from true discharge rates through- i out the range of expected discharge volumes. Guidance in selection, l installation, calibration and operation of acceptable flow measure-  !

sent devices can be obtained from the following references:

2. A grab sample is defined as an individual sample of at least 100 milliliters collected over a period not exceeding 15 minutes. Grab samples shall be collected at times when wastewater flows and characteristics are most demanding on the treatment f acilities.

3. Temperature shall be recorded at a minimum frequency of once every two hours. The average and maximum temperature for each 24-hour period shall be reported.

4. Samples shall be collected and analyzed for pH during chlorination.

Combined discharge monitoring shall be conducted at a point in the circulating water syntes downstreme of the condenser, downstream of the point (s) at which the component cooling and turbine plant cooling water streams reenter the circulating water streas, and downstream of the point (s) at which all in-plant vaste steams enter the circulating water stream. Combined discharge samples shall be collected immediately following collection of cooling water intake samples.

7. Samples shall be collected and analysed for hydrazine on the day (s) of the sonth when the hydrazine concentration is the greatest, but no less frequently than once each month.

8. Samples shall be collected and onlyzed for toxicity concentrations no less frequently than once each week if, at any time, the toxicity concentration exceeds 0.55 tu. Collection and analysis of samples for toxicity concentration on a weekly basis shall continue until measured toxicity concentration is less than 0.55 tu. In addition, the toxietty concentration shall be determined when the hydraniu concentration is anticipated to be at a maximus. Toxicity concentration shall be sensured in the following manners (a) Toxicity Concentration (Tc)

TIJs (percent vaste giving 50 percent survival of test organissa) i shall be determined by seatic or continuous Tow bioassay techniques using standard test species. If epecific iu ntifiable substances in vastewater can be demonstrated by the discharger as being rapidly rendered harmless upon discharge to the marine environment, but not as a result of dilution, the Tim may be determined after the test semples are adjusted to remove the influence of those substances.

When it is not possible to measure the 96-hour TLa due to greater than 50 percent survival of the test species in 100 percent waste, the toxicity concentration shall be calculated by the expression:

Te (tu) = log (100-S) 1.7 5 = percentage sutvival in 100 percent waste.

If S > 99 Tc shall be reported as sero.

If the calculated value for toxicity concentration in the combined discharge falls below the limit of detection of the test method specified in the code of federal roulations 40 CFR, Part 136 "Guidelines Establishing Test Procedures for Analysis of Pollutants " or by a more sensitive method specified by the State Water Resources Control Board or the Regional Board, the limit of detection shall serve as the limiting effluent concentration. The limit of detection of acute toxicity in standard test methods is less than, or equal to. 0.59 tu.
