Approved By - Procedure N imber Rev ShanSundram ogtle Electric Genierating Plant 360C: 1 Date Approved NPDES PERMIT IMPLEMENTATION AND CONTROL Page Number 12/09/2004 ,! of 48 INFORMATION USE 1.0 PURPOSE This procedure outlines sampling and shipping instructions for compliance with the Vogtle National Pollutant Discharge Elimination System (NPDES) permit (See Figure 4). It also outlines instructions for handling the quarterly report, flow study, breakdown logs, and priority pollutant certification.

2.0 PRECAUTIONS AND LIMITATIONS 2.1 If any conflict results between this procedure and the NPDES permit, this procedure shall be revised to conform to the NPDES permit.

2.2 IMMEDIATELY notify laboratory supervision of any NPDES Waste Treatment System that is inoperable, bypassed or overflowing.

2.3 Due to plant Vogtle's unique Circulating Tower Flume blowdown design, simultaneous chlorination is interpreted by Corporate Environmental Affairs as being in compliance with the NPDES permit.

2.4 Biological growth and stability index are controlling factors in determining the need for simultaneous chlorination.

2.4 NPDES samples should be obtained and analyzed early in the day so that an additional sample or confirmatory sample can be obtained and analyzed within the same day if deemed necessary by Chemistry Management.

2.5 NPDES exceedences may require a 24-hour notification to the Georgia EPD. Therefore, for all exceedences immediately notify the Control Room and Chemistry Management.

2.6 Waste water retention basin (wwrb) samples must be obtained from either the main or alternate sample points while the basins are being discharged. Samples obtained while the basins are on "recirc" are considered "information only" and are not normally considered to be valid samples for the NPDES compliance. These information only samples should be annotated accordingly on the log sheet and in the database.

2.7 The NPDES permit expiration date may be extended by the Georgia Department of Natural Resources-EPD beyond the date shown on the original permit. Written notification of this extension should be filed with Environmental Services.

3.0 PREREQUISITES AND INITIAL CONDITIONS Sampling for environmental parameters shall be conducted periodically per Procedure 30025-C, "Periodic Analysis Scheduling Program".

1. Within 90 days of Division notification a screening program study plan detailing the test methodology and test organisms shall be submitted for conducting a forty-eight hour static acute test of the final effluent.

Note: If residual chlorine is present in the final effluent from a treatment and/or disinfection process, a prechlorinated or dechlorinated sample will be tested.

2. Within 90 days of Division approval of the study plan, the permittee shall conduct and submit the results of the forty-eight hour static acute test.

The Division will then review the results of the forty-eight hour static acute test. If the test criteria specified in the study plan are exceeded, then the permittee shall within 90 days of written notification by the Division repeat steps 1.

and 2. a;ove replacing the forty-eight hour static acute test with the ninety-six hour test.

The Division will then review the results of the ninety-six hour test. If the criteria* detailed in the ninety-six hour test indicates toxicity, then the permittee shall within 90 days of written notification by the Division submit to the Division a plan to reduce the toxicity of the effluent. Within 270 days of Division approval of this plan, the permittce shall implement the plan and initiate follow-up biomonitoring of the effluent in accordance with the approved toxicity reduction plan. The toxicity reduction plan shall not be complete until the permittee meets the criteria detailed in the ninety-six hour test plan.

If there are substantial composition changes in the permettee's effluent, the permittee may be required to repeat the forty-eight hour static acute test upon notification by the Division. Unless otherwise advised, the permittee shall perform biomonitoring of the effluent as provided in C. 1. and 2. above, at a minimum of once every three years upon notification by the Division. On a case specific basis, chronic toxicity testing procedures may be required.

Upon approval by the Division, all of the plans will become part of the requirements of this permit.

• The 96 hour0.00111 days <br />0.0267 hours <br />1.587302e-4 weeks <br />3.6528e-5 months <br /> criteria shall define toxicity as a greater than 10% mortality of the exposed test organisms in 96 hours0.00111 days <br />0.0267 hours <br />1.587302e-4 weeks <br />3.6528e-5 months <br /> or less when the test solution contains volumes of effluent and dilution water proportional to the plant daily average flow and the 7Q10 flow of the receiving stream, as determined using test procedures and methods, and statistical methods for evaluating test results, developed by the permittee and approved by the Division pursuant to this section or revised pursuant to Part III.B. 16. above.
