6. §316(b) ofthe Clean Water Act (CWA) & Cooling Water Intake Structures

a. Nothing in this permit authorizes take for the purposes of a facility 's compliance with the Endangered Species Act.

b. EPD has made a site~specific determination that closed~cycle cooling represents final BTA for impingement mortality and entrainment. The permittee shall operate a closed-cycle recirculating system to achieve compliance with this site-specific determination. The permittee must monitor the actual intake flows at a minimum frequency of daily. The monitoring must be representative of normal operating conditions, and must include measuring cooling water withdrawals, make-up water, and blowdown volume. In lieu of daily intake flow monitoring the permittee may monitor the cycles of concentration at a minimum frequency of daily. Monitoring will be included in the OMR and submitted in accordance with Part I.D of the permit.

c. The permittee must either conduct visual inspections or employ remote monitoring devices on at least a quarterly basis during the period in which the cooling water intake structure is in operation. Such inspections must ensure that the cooling towers operated to comply with 40 CFR 125.94 (impingement mortality and entrainment requirements) are maintained and operated to function as designed.

The permittee must prepare an inspection report documenting the inspections or monitoring and the inspection report shall be submitted as an attachment to the DMR in accordance with Part I.D of the permit. The inspection report shall contain the following minimum elements:

1. Date, time, and location of the inspection or remote monitoring; ii. Water withdrawal rate during the time of the inspection; iii. Equipmentffechnology identified as needing maintenance, repair or replacement, if any; and iv. Name(s) and signature(s) of the inspector(s)

An inability to conduct visual inspections or employ remote monitoring devices because of adverse weather conditions during a monitoring period will not constitute failure to monitor as long as those conditions are docwnented in the inspection report. Documentation of an adverse event interfering with the visual inspections or remote monitoring (with date, time, and written description) must be submitted with the DMR.

d. The permittee shall submit an annual certification statement signed by the responsible corporate officer certifying either; no substantial operational changes have occurred at the facility that impact cooling water withdrawals or operation of the cooling water intake structures, or that substantial modifications have occurred.

The certification statement should be submitted as an attachment to the DMR due June 15th.

STATE OF GEORGIA DEPARTMENT OF NATURAL RESOURCES Page 32 of34 ENVIRONMENTAL PROTECTION DIVISION Permit No. GA0026786

1. If the information contained in the previous year's annual certification is still pertinent, the permittee may simply state as such in a letter to the Director and the letter shall constitute the annual certification.

n. If substantially modified operation of any unit has occurred at the facility that impacts cooling water withdrawals or operation of the cooling water intake structures, the permittee shall provide a summary of those changes in the report. In addition, revisions to the information required at 40 CFR t 22.2 t (r) must be submitted with the next permit application.

e. The permittee shall retain records of all submissions related to the permit application and permit conditions outlined in Part III.C.3 of this permit until the subsequent has been issued.

f. The permittee may in subsequent permit applications, request to reduce the information required in the 40 CfR 122.21(r) permit applications studies, if conditions at the facility and in the waterbody remain substantially unchanged since the previous application so long as the relevant previously submitted information remains representative of current source water, intake structure, cooling water system, and operating conditions. The permittee must submit its request for reduced cooling water intake structure and waterbody application information to the Director at least two years and six months prior to the expiration of its NPDES permit. The permittee's request must identify each element in this subsection that it determines has not substantially changed since the previous permit application and the basis for the determination.

7. Thermal Mixing Zone & Temperature Modeling

a. The approved thermal mixing zone is defined as the segment of the river extending 81 feet downstream from the point of discharge with a width of 22 feet extending from the west river bank. The downstream sampling location for compliance with the temperature requirements outlined in Part I.A. t of this permit is along the downstream edge of the defined mixing zone at a depth of one ( 1) meter.

b. Within 24 months of the effective date of the permit, the permittee shall develop a temperature model for Outfall No. 001 and submit the model to EPD for review and approval. The model shall reflect the critical periods of the year, the summer months during low flow for the 90 °f maximum water quality standard and for the winter months for the delta 5 °f water quality standard. The results of the model will be used to verify the extent of the established mixing zone. EPD may reopen the permit to modify the extent of the mixing zone if the model indicates such a need.

STATE OF GEORGIA DEPARTMENT OF NATURAL RESOURCES Page 33 of34 ENVIRONMENTAL PROTECTION DIVISION Permit No. GA0026786

8. Benchmark Monitoring

a. External outfall nos. 013 and 0 14 shall be subject to the following benchmarks:

Benchmark Monitoring Monitoring Parameter Concentration Frequency Oil & Grease 15 mg/L Annual Dissolved Copper 0.0038 mg/L Annual Dissolved Nickel 0.15mg/L Annual Dissolved Zinc 0.04 mg/L Annual

b. Benchmark concentrations are not effluent limitations; a benchmark exceedance, therefore, is not a non-compliance with a permit eftluent limitation. If after collection of the annual sample, if the value of any parameter exceeds the benchmark, the permittee must review the selection, design, installation, and implementation of control measures in the Stormwater Pollution Prevention Plan (SWPPP) to determine if modifications are necessary to meet the benchmarks in this permit, and either:

1. Make the necessary modifications and continue sampling each subsequent quarter until the benchmark is met; or

n. Make a determination that no further pollutant reductions are technologically available and economically practicable and achievable in light of best industry practice to meet the non-numeric technology-based effluent limits identified in the SWPPP, in which case permittees must continue monitoring once per year. This determination is a one-time occurrence during the permit term and can be relied upon for the duration of the permit term, so long as there are no significant construction or changes in design, operation, or maintenance at the facility that significantly changes the nature of pollutants discharged in stormwater from the facility or significantly increases the quantity of pollutants discharged. Permittees must document the rationale for concluding that no further pollutant reductions are achievable, and retain all records related to this documentation with the SWPPP. Permittees must notify EPD of this determination as required by Section Part I.D of this permit.

iii. Permittees must review control measures and perform any required corrective action as quickly as possible (or document why no corrective action is required). If after modifying control measures and additional quarterly monitoring, the sample value still exceeds the benchmark, permittees must again review control measures and take one of the two actions above.

c. The permittee shall have a written Stormwater Pollution Prevention Plan onsite.

STATE OF GEORGIA DEPARTMENT OF NATURAL RESOURCES Page 34 of34 ENVIRONMENTAL PROTECTION DIVISION Pennit No. GA0026786 D. Biomonitoring and Toxicity Reduction Requirements

1. The permittee shall comply with effluent standards or prohibitions established by section 307(a) of the Federal Act and with chapter 391-3-6-.03(5)(e) of the State Rules and may not discharge toxic pollutants in concentrations or combinations that are harmful to humans, animals, or aquatic life.

If toxicity is suspected in the effluent, EPD may require the permittee to perform any of the following actions:

a. Acute biomonitoring tests;

b. Chronic biomonitoring tests;

c. Stream studies;

d. Priority pollutant analyses;

e. Toxicity reduction evaluations (TRE); or

f. Any other appropriate study.

2. EPD will specify the requirements and methodologies for performing any of these tests or studies. Unless other concentrations are specified by EPD, the critical concentration used to determine toxicity in biomonitoring tests will be the effluent instream wastewater concentration (IWC) based on the representative plant flow of the facility and the critical low flow of the receiving stream (7Q 10). The endpoints that will be reported are the effluent concentration that is lethal to 50% of the test organisms (LCSO) if the test is for acute toxicity, and the no observed effect concentration (NOEC) of effluent if the test is for chronic toxicity.

The permittee must eliminate effluent toxicity and supply EPD with data and evidence to confirm toxicity elimination.
