Appendix B of the South Texas Project Operating License requires the NRC be provided a copy of the application for renewal of the TPDES Permit at the same time the application is submitted to the permitting agency. Due to misinterpretation of Appendix B, this requirement was not fulfilled in a timely manner and is being tracked in the Corrective Action Program. The requirement to submit the wastewater discharge permit application is being evaluated for deletion from Appendix B.

There are no commitments in this letter.

Texas Commission on Environmental Quality 12100 Park 35 Circle Austin, Texas 78753 Re: TPDES Permit Renewal Application South Texas Project Electric Generating Station TPDES Permit No. 01908

Dear Sir/Madam:

STP Nuclear Operating Company (STPNOC) submits the enclosed TPDES permit renewal application (one original and three copies) for the South Texas Project Electric Generating Station (STPEGS). STPNOC is the authorized agent for the owners of the facility. The Texas Commission on Environmental Quality (TCEQ) transferred the permit to the STPNOC on September 18, 2003. Attached is the order transferring the permit to the STPNOC and a copy of the check for the permit renewal fee that has been sent to the Revenues Section of the TCEQ.

Although the STPEGS is a major power generating facility, it is not subject to the recently promulgated CWA §316(b) regulations. The facility employs recycle cooling water technology rather than the once through cooling systems affected by the Phase II regulations.

If you have any questions regarding this letter, or the enclosed application or attachments, please contact Doug Welch at (713) 945-7892 or by e-mail at dbwelchgtxgenco.com.

SUMMARY

Water Well Report Tiesearch Mapping Protocol The Banks Information Solutions, Inc. Water Well Report is prepared from existing state water well databases and additional file datalrecords research conducted at Texas' regulatory authorities. Submission of drilleres 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 four filing systems utilized for well drilling records.

Texas Water Development Board (TWDB)

Texas Water Development Board maintains a file system of located water well locations. 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 and plotted on county base maps, U.S.G.S. 7.5 minute topographical quadrangle maps, and in-house geographic Information system. Records will also Include analytical data attached with each drilling record. This Is the current protocol for maintaining water well records within the TWDB.

Texas Commission on Environmental Quality (TCEQ)

The Texas Commission on Environmental Quality maintains a file system of plotted, partially numbered, and un-numbered water well locations. 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. This type of mapping and filing procedure ceased In June 1986. Partially numbered water well files are water well site locations processed from 1986 through 1990. These wells are provided a State Identification Number which establishes the well location somewhere within a 2.5 minute quadrant of a 7.5 minute quadrangle map, but the site location has never been precisely mapped or verified by a State of Texas staff member. Un-numbered 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 Identiflation Number nor are they mapped. This Is the current protocol for maintaining water well records within the TCEQ.

Disclaimer Banks Information Solutions, Inc. 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. Therefore, Banks Information Solutions, Inc. cannot gaurantee the accuracy of the data or well location(s) of those maps and records maintained by Texas' regulatory authorities.

APPENDIX TR-lc Cross Reference-Technical Report, Page 1, Part 1.c.

l.e. Describe the wastewater generating process.

Wastewater is produced at the South Texas Project Electric Generating Station through several processes necessary for electricity generation.

Main Cooling Reservoir (Outfall 001)

Outfall 001 has not discharged since March 1997 other than minor permitted leakage through the closed spillway gates. Blowdown from the 7,000-acre main cooling reservoir would make up the largest percentage of wastewater if a reservoir discharge were to occur. This reservoir is part of the main recirculating cooling water loop used to remove heat from the two steam-electric generating units. Water from the reservoir would be discharged through Outfall 001 to Colorado River Tidal - Stream Segment 1401. Again, Outfall 001 has not discharged since March 1997. Because no discharge has occurred since then, no sampling data was provided with this application. Reference Appendix TR-2b Figure 1 of 6 for a simplified flow diagram.

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. These internal outfalls discharge from the various systems described below and within this permit application.

Reference Appendix TR-2b Figures 1 through 6.

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 water from the one-auxiliary steam boiler that is released to reduce concentrations of impurities in the water that would cause corrosion and boiler tube failure.

Demineralizer regeneration wastewater results from demineralizing service water to purify and treat it before being used in plant systems. 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 have the potential to have oil or grease contamination. The water is then transported to the oily waste treatment system where the oil is separated from the water. The first flush of stormwater from some production and storage areas is also treated in the oily waste system with other non-process stormwater flow directed through the designated stormwater outfills. Reference Appendix TR-2b Figures 2 and 3 of 6.

Treated Domestic Wastewater (Outfalls 401 and 601)

Domestic wastewater is treated on-site in two package treatment systems consisting of aeration, clarification, and disinfection. Car wash water, air conditioning condensate, and HVAC cooling tower blowdown are commingled with the domestic wastewater prior to treatment. Reference Appendix TR-2b Figures 4 and 5 of 6.

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). Reference Appendix TR-2b Figure 2 of 6.

MEDICAL CONDITIONS POSSIBLY AGGRAVATED BY EXPOSURE:

Inhalation of product may aggravate existing chronic respiratory problems such as asthma, emphysema or bronchitis. Skin contact may aggravate existing skin disease.

NOTES TO PHYSICIAN:

All treatments should be based on observed signs and symptoms of distress in the patient. Consideration should be given to the possibility that overexposure to materials other than this product may have occurred.

This material is an acid. The primary toxicity of this product is due to its irritant effects on mucous membranes.

INHALATION: If cough or shortness of breath occurs, evaluate the possibility of bronchitis or pneumonitis. Chest x-ray and arterial blood gases can be used to determine the presence of pulmonary edema.

In severe cases, use of humidified oxygen and assisted ventilation including positive end expiratory pressure (PEEP) may be needed.

Parenteral steroids may be useful in limiting the extent of pulmonary damage.

SKIN: Wash exposed area thoroughly with soap and water. Chemical burns from strong acids are generally treated the same as thermal burns.

Toxicological Information and Interpretation LD50 - lethal dose 50% of test species, 2140 mg/kg, rat.

Chronic Toxicity:

This product contains the substances that are considered to be "probable" or "suspected" human carcinogens as follows:

The International Agency for Research on Cancer (IARC) and the National Toxicology Program (NTP) have classified "occupational exposure to strong inorganic acid mists containing sulfuric acid" as a known human carcinogen (IARC Category 1). This classification applies only to sulfuric acid when generated as a mist. There is still debate in the scientific community whether the studies reviewed by IARC and NTP adequately controlled for confounding occupational exposures and personal habits such as cigarette smoking and alcohol consumption. A few epidemiology studies have suggested a possible association between sulfuric acid exposure and laryngeal or lung cancer; however, in all these studies, workers were exposed to many other chemicals, some of which are recognized carcinogens, such as diethylsulfate and nickel.

Considering the multiple chemical exposures and other limitations of the studies, we disagree with IARC's conclusion that a cause and effect relationship between cancer and "occupational exposure to strong inorganic acid mist containing sulfuric acid" has been demonstrated.

Also more recent epidemiological studies have failed to find any association between "occupational exposure to strong inorganic acid mist containing sulfuric acid" and laryngeal or lung cancer. ACGIH has classified "sulfuric acid as contained in strong inorganic acid mists" as a suspect human carcinogen. This classification does not apply to sulfuric acid per se.

Lifetime animal studies in hamsters, rats and guinea pigs were conducted in the 1970's under sponsorship of the Environmental Protection Agency (EPA) or the National Institutes of Environmental Health Sciences (NIEHS). All three lifetime studies were negative for carcinogenic effects. These studies were not formally published by the government agencies because they were satisfied that sulfuric acid mist was not a carcinogenic problem. Because these studies were not published, IARC or NTP did not consider them in their deliberations.
