TECHNICAL REPORT 1.0 - INDUSTRIAL THE FOLLOWING IS REQUIRED FOR ALL APPLICATIONS, RENEWAL, NEW, AND AMENDMENT

1. FACILITY/SITE INFORMATION (Instructions, page 24)

a. Describe the type of activity and general nature of your business.

South Texas Project (STP) Electric Generating Station is a nuclear fueled, steam-electric generating facility. Electricity is generated from steam driven turbines.

b. SIC Code(s) 4911 NAICS Code(s) 221113 , ,

c. Describe the wastewater generating processes.

Main Cooling Reservoir - Outfall 001 Outfall 001 is the discharge point for the 7,000-acre main cooling reservoir. This reservoir is part of the main recirculating cooling water loop used to remove heat from the steam-electric generating units. There has not been a discharge from Outfall 001 since March 1997 other than minor permitted leakage through the closed spillway gates and relief wells. If a discharge were to occur, blowdown from the main cooling reservoir would make up the largest percentage of wastewater. A discharge from Outfall 001 would flow to the Colorado River (Colorado River Tidal in Segment 1401 of the Colorado River Basin).

All internal outfalls (Outfall 101, 201, 401, and 601) discharge to the main cooling reservoir. Outfall 501 would also discharge to the reservoir via Outfall 101, but has not discharged since 1992.

Low Volume Wastewater (Outfalls 101 and 201)

Low volume wastewater results from water treatment operations, boiler blowdown, HVAC blowdown, floor drains and SPCC sources and their associated oily water treatment system discharges, and other miscellaneous sources. Boiler blowdown is from one auxiliary steam boiler, released to reduce impurities in the water that can cause corrosion and boiler tube failure. Service water is demineralized and regeneration of the demineralizer resin beds produces an acidic and caustic wastewater that is treated at the neutralization basins along with boiler blowdown. The floor drain system captures condensate and water from production and maintenance areas that may contain oil or grease, which is then transported to the oily waste treatment system where the oil is separated from the water. The first flush of storm water from some production and storage areas is also treated in the oily waste system. Other non-process storm water flow is directed through designated storm water outfalls.

Treated Domestic Wastewater (Outfalls 401 and 601)

Domestic wastewater is treated onsite in two package treatment systems consisting of aeration, clarification, and disinfection. Car wash water, air conditioning condensate, HVAC cooling tower blowdown, and storm water are commingled with the domestic wastewater prior to treatment.

Metal Cleaning Waste (Outfalls 501)

Metal cleaning waste has not been discharged since 1992. Cleaning of metal using chemical or non-chemical liquids produces a waste that would be discharged through Outfall 501 to the neutralization basins (Outfall 101). Storm water may also be discharged through Outfall 501.

d. Provide a list of raw materials, major intermediates, and products handled at your facility.

• Because there have been no discharges from Outfall 001 since 1997, samples were taken from the Main Cooling Reservoir for effluent characterization, as allowed per the application instructions (pg. 37).

• • EPA 200.7 used for titanium analysis.

• • • Initial test results for sulfites ranged from 24-52 mg/L, but are believed to be false positives due to matrix interference. These samples were collected from the Main Cooling Reservoir. It is an open air impoundment where oxygen in the water would readily oxidize sulfite to sulfate. Dissolved oxygen was measured in the recirculating loop from the reservoir following the sulfite analyses and found to be over 5 mg/L, indicating that no sulfite could be present.

Nuclear Operating Company South T*has ProlotElectric Generating Statibon PO. Box 289, Wadsworth. TCxas 77483 May 24, 2007 NOC-TX-07016176 PFN: W02 STI No. 32165797 Mr. Kelly Holligan Team Leader, Industrial Wastewater Permits Texas Commission on Environmental Quality P.O. Box 13087 Austin, TX 78711-3087 Re: Cooling Water Intake Structures Phase II Rules South Texas Project Electric Generating Station TPDES Permit No. 01908

Dear Mr. Holligan:

Thank you for meeting with my staff on May 15, 2007 to discuss the South Texas Project Electric Generating Station (STPEGS) cooling reservoir and other wastewater discharge permit issues. Based on our discussion, STP Nuclear Operating Company (STPNOC) is submitting the following information regarding the Main Cooling Reservoir (MCR) and the applicability of the regulations for cooling water intake structures. We are confident that the South Texas Project Station (STP) complies with the regulation by employing a closed-cycle recirculating cooling system as defined in 40 CFR §125.93. Pursuant to 40 CFR §125.94(a)(1)(i), cooling water flow for this facility is commensurate with a closed-cycle recirculating cooling system, as demonstrated below. Additional technical information is included in letters dated March 7, 2005 and August 18, 2005 previously submitted to the Texas Commission on Environmental Quality (TCEQ).

STP is located on 12,220-acres in Matagorda County, approximately 15 miles southwest of Bay City along the west bank of the Colorado River. The facility consists of two electric-generating units, which share a closed-cycle recirculating cooling reservoir. Water from the MCR is passed through the cooling loops of both units then returned to the MCR for heat dissipation before cycling back through the cooling systems.

The MCR is a perched, off-channel, on-site industrial cooling impoundment of approximately 7,000 acres, impounding over 202,600 acre-feet of cooling water at its maximum operating level.

Dikes are installed in the MCR that channel the water flow to maximize circulation time for heat dissipation before the water is recirculated back to the generating units. Blowdown from the MCR to the Colorado River has not occurred since March 1997. Should blowdown be required it would occur through an underground pipe that discharges back into the Colorado River. This point is designated as Outfall 001 in the TPDES Penmit No. 01908. The MCR is also equipped with a gated spillway for emergency use. The MCR is not a "water of the U.S." as defined at 40 CFR § 122.2. The MCR is not considered a "water of the State" based on internal and external outfall designations in the permit. The MCR is on private property and exists solely for

Mr. Kelly Holligan May 24, 2007 Page 2 industrial cooling. It is not a publicly managed water body and has no recreational uses. The general public has never had access to the MCR nor is any planned in the foreseeable future.

The only sources of new water to the MCR are direct rainfall and make-up water diverted periodically from the Colorado River, primarily at high river flows. Water from the Colorado River is pumped approximately 1 mile via a 108 inch pipe to the MCR. To protect inflows during low river flow conditions, the water right for STP includes a special provision to limit diversion from the Colorado River to 55% of the flow over 300 cubic feet per second, to protect inflows during low river flow conditions. Currently, the intake consists of trash racks, rotating screens with 3/8 inch mesh and 4 pumps. In addition, the reservoir makeup pumping facility has the following design:

• The traveling water screens are flush with the river shoreline;

• The maximum approach velocity to the traveling water screens is 0.5 feet per second;

• Fish passageways were constructed in the wing walls between the traveling screens to facilitate fish migration parallel to the screen surfaces; and

" A sluice and discharge line was installed for the purpose of returning all impinged organisms directly to the river, downstream of the intake structure, immediately after being backwashed from the screens.

The pumps are operated intermittently based on reservoir level, river flow, and the operability of the makeup pumping facility. A cooling reservoir evaporates less water per unit of heat dissipated than a cooling tower, thus dissolved solids build up more slowly over time. This is complemented by the designed seepage from the MCR, which maintains the structural integrity of the reservoir embankment. Rainfall further dilutes the dissolved solids in the MCR. These factors minimize the blowdown and make-up required to maintain MCR water quality. As a result, intake water flow for cooling purposes at STP reflects best technology available (closed-cycle recirculating systems) for minimizing adverse environmental impact.

As was discussed in the May 15, 2007 meeting, several provisions of the Phase II rule are in the process of being suspended by the U.S. Environmental Protection Agency and the Regional Administrators have been authorized to review the applicability of the rule on a case by case basis using Best Professional Judgment. Based on that authorization and the information provided, STPNOC is requesting that TCEQ designate the MCR as a closed-cycle recirculating system. We are also requesting concurrence that the MCR does not meet the definition of a "water of the State". If you have any questions or require additional information, please contact Ms. S. L. Dannhardt at (361) 972-8328.

Dear Mr. Gangluff:

I received your letter dated May 24, 2007, requesting that the Main Cooling Reservoir (MCR) be designated as a closed-cycle recirculating system and as not water in the state.

The Texas Commission on Environmental Quality (TCEQ) does not have an official method of "designating" a facility's operation as a closed-cycle recirculating system. However, we have reviewed the information you submitted and based on our best professional judgement, we consider your facility to be a closed-cycle recirculating system. As mentioned in your letter, the federal rule governing the 316(b)

Phase II cooling water intakes is currently in the process of being suspended. For the time being, implementation of the 316(b) requirements will be based on best professional judgement (BPJ) and subject to EPA Region VI review.

We also concur that the Main Cooling Reservoir (MCR) at your facility does not meet the definition of water in the state.

If you have any questions, please contact me at (512) 239-2369.

Sincerely, Kelly Holligan, Leader Industrial Team Water Quality Division KH/jp P.O. Box 13087 Austin, Texas 78711-3087

BANI(S Water Well Report ENVIRONMENTAL DATA ADIVISION OF THE BANKS GROUP DISCLAIMER Water Well Report Research Mapping TM The Banks Environmental Data Water Well ReportTM is prepared from existing state water well databases and additional file data/records research conducted at Texas' regulatory authorities. Submission of driller's log records upon completion of a drilled water well became mandatory in 1985. The state of Texas has processed these records into several different filing systems within two state regulatory authorities. The water well files, records and map locations are maintained by the Texas Commission on Environmental Quality (TCEQ) and the Texas Water Development Board (TWDB). Actual water well site locations of this report are geocoded and geoplotted directly from the drilling records, drilling schedules, and driller's logs and maps submitted by the water well driller and maintained at these two primary water well regulatory authorities. Below is a description of the filing systems utilized for well drilling records.

Texas Water Development Board (TWDB)

The Texas Water Development Board maintains two datasets of located water well records:

TWDB Groundwater Data-These well files are water well site locations that have been verified with a field inventory inspection by TWDB personnel. The wells are assigned a State Identification Number unique to that well (ex. 65-03-401) and plotted on county base maps, U.S.G.S. 7.5 minute topographical quadrangle maps, as well as in-house and on line geographic information systems. Records may also include analytical data attached with each drilling record.

TWDB Submitted Drillers Reports- A Database created from the online Texas Well Report Submission and Retrieval System (A cooperative TDLR, TWDB system) that registered water-well drillers use to submit their required reports. Reports that drillers submit by mail are geoplotted/geocoded by a TWDB staff member. These wells are assigned a unique tracking number by the Texas Well Report Submission and Retrieval System. This system was introduced in February 2001 as an option for drillers to use, and will be mandatory in the future.

Texas Commission on Environmental Quality The Texas Commission on Environmental Quality (TCEQ) maintains two datasets of water well records.

Water Utility Database (WUD) - This database contains a collection of data from Texas Water Districts, Public Drinking Water Systems and Water and Sewer Utilities who submit information to the TCEQ. These wells are assigned unique numbers with correlate to the Public Water System they act as a source for (example- $2200199A, G2200322A). The WUD does not contain Drillers Reports or analytical data. This data was provided to Banks in digital format.

TCEQ Central Records-Several different types of Driller's Reports are filed with TCEQ Central Records according to the State Grid Number.

Plotted water well files are water well site locations that have been determined from map information submitted on water well logs and subsequently plotted on TWDB county highway base maps. The accuracy and location of these wells is relative to the information provided on the drillers report. TWDB assigned letters to the correlating grid number to identify these wells (example 59-1A). In some instances, a single well number can represent more than one well location. This type of mapping and filing procedure ceased in June 1986.

Partially numbered water wells -Well Reports that were provided a State Identification Number by the TWDB which establishes the well location somewhere within a 2.5 minute quadrant of a 7.5 minute quadrangle map. This method was the standard procedure from 1986 through 1991. From 1991 to the 2001, Texas Well Reports contain a grid location box, where drillers are provided a place to mark an X where within the 2.5 minute quadrant is located. These locations have not been verified by the state.

Unnumbered water well files are water well site locations that have been processed since June 1990. These well records are filed solely on their county location and are not provided a State Identifiation Number nor are they mapped.

Disclaimer Banks Environmental Data has performed a thorough and diligent search of all wells recorded with the Texas Water Development Board and the Texas Commission on Environmental Quality. All mapped locations are based on information obtained from the TWDB and the TCEQ. Although Banks performs quality assurance and quality control on all research projects, we recognize that any inaccuracies of the records and mapped well locations could possibly be traced to the appropriate regulatory authority or the water well driller. Many water well schedules may have never been submitted to the regulatory authority by the water well driller and, thus, may explain the possible unaccountability of private drilled wells. It is uncertain if the above listing provides 100% of the existing well locations within the area of review.
