TXU ENERGY COMANCHE PEAK STEAM ELECTRIC STATION UNITS1 &2 2003 ANNUAL ENVIRONMENTAL OPERATING REPORT (NON-RADIOLOGICAL)

FACILITY OPERATING LICENSE NOS. NPF-87 & 89

Attachment to TXX-04078 Page 2 of 9 I. INTRODUCTION This report describes implementation of the Environmental Protection Plan (EPP) for the calender year 2003 as required by Appendix B to Facility Operating License Nos. NPF-87

& 89 for Comanche Peak Steam Electric Station (CPSES) Units 1 & 2.

During 2003, the CPSES Nonradiological Environmental Monitoring Program was effective in implementing and monitoring all CPSES environmental regulatory commitments.

Program effectiveness in 2003 was substantiated by TXU Corporate environmental audits, compliance evaluations conducted by the CPSES Nuclear Overview Department, and department self-assessments.

II. SCOPE Section 5.4.1 of the EPP requires that CPSES submit to the NRC an Annual Environmental Operating Report that shall address the following environmental protection activities:

A. Summaries and analyses of the results of the environmental protection activities required by Section 4.2 of the EPP, including a comparison with related preoperational studies, operational controls (as appropriate), and previous nonradiological environmental monitoring reports, and an assessment of the observed impacts of plant operation on the environment. If harmful effects or evidence of trends toward irreversible damage to the environment are observed, a detailed analysis of the data and a proposed course of mitigating action is required.

Section 4.2 of the EPP pertains to results from:

1. Groundwater levels and station water use monitoring.

2. Water treatment facility outages impact assessment and reporting.

B. The report shall also include:

1. A list of EPP noncompliances and the associated corrective actions.

2. A list of all changes in station design and operation, tests, and experiments made in accordance with Subsection 3.1 of the EPP which involved a potentially significant unreviewed environmental question.

3. A list of nonroutine reports submitted in accordance with Subsection 5.4.2 of the EPP.

4. A summary list of Texas Pollutant Discharge Elimination System (TPDES) permit related reports relative to matters identified in Subsection 2.1 of the EPP which were submitted to the Texas Commission on Environmental Quality (TCEQ) during the report period. Subsection 2.1 of the EPP pertains to aquatic matters that are addressed by the effluent limitations, and the monitoring requirements contained in the TCEQ TPDES station wastewater discharge permit.

Attachment to TXX-04078 Page 3 of 9 Ill. RESULTS OF ACTIVITIES A. As required by Subsection 4.2 of the EPP, the following are summaries and analyses of the environmental protection activities during 2003. Based on the results of these activities, there were no observed adverse environmental impacts resulting from plant operation during 2003.

1. Groundwater Pumpage As indicated in Table 1, groundwater pumpage during 2003 averaged 18.0 gals./min. (gpm) or 9,441,000 total gallons withdrawn for the year. This withdrawal rate represents a 18% decrease from the 2002 average rate of 22.0 gpm. Groundwater withdrawal was highest in October at 23.6 gpm and lowest in November with an average withdrawal rate of 11.7 gpm.

Groundwater withdrawn during 2003 was used primarily for potable and sanitary purposes with only a very small amount used as make-up to the plant fire protection system. No groundwater was used to supplement the station's Surface Water Treatment System.

The average annual pumpage rate of 18.0 gpm for 2003 represents 14.2%

of the predicted operational pumpage (127 gpm) identified in Section 3.3 of the Station's Environmental Report - Operational License Stage. This rate also represents approximately 11 % of the actual average withdrawal rate (158 gpm) reported in the Station's Final Environmental Statement -

Operating License Stage (Section 5.3.1.2) for the period 1975 to May 1979.

The combined annual rate for all recorded preoperational groundwater pumpage averaged 68.8 gpm, while the average operational pumpage for the period 1990 through 2003 was 28.2 gpm. Therefore, the average operational rates are 59% less than the groundwater pumpage during the preoperational period. Figure 1 illustrates the annual fluctuation of groundwater withdrawal over the entire preoperational and operational period.

2. Groundwater Levels As indicated in Table 2, the groundwater level in the on-site observation well OB-3 (intersection of Highway 56 and the Plant Access Road) fluctuated during 2003 from a high level in April of 528.1 ft. Mean Sea Level (MSL) to a low level in September of 522.9 ft. MSL. Overall, the water level in OB-3 during the reporting period (January through December) decreased 1.9 ft.

(0.6m).

The 2003 annual average groundwater levels in well OB-3 and OB-4 were 525.8 ft. MSL and 558.6 ft. MSL, respectively. These average levels demonstrated an increase of 0.1 ft. (0.03m) for OB-3 and a decrease of 1.1 ft. (0.3m) for OB-4 from the respective average 2002 levels (Figure 2).

3. Surface Water Treatment System Operation The station's Water Treatment System processed 166,876,900 total gallons (317.5 gpm) of surface water during 2003 for plant process use. There were no outages during 2003 that required reporting in accordance with Section 4.2.2 of the EPP.

The following is a summary list of monthly surface water usage:

EPP Noncompliance and Corrective Actions - Subsection 5.4.1(1)

There were no noncompliances with the requirements of the EPP during the reporting period.

C. Changes In Station Design or Operation, Tests, and Experiments Made In Accordance With Subsection 3.1 Which Involved A Potentially Significant Unreviewed Environmental Question.

There were no changes in station design, operation, tests or experiments conducted during the reporting period that are reportable under this subsection.

D. Nonroutine Reports Submitted In Accordance With Subsection 5.4.2 Other than those nonroutine reports identified in section III.E, there were no other nonroutine reports submitted under this subsection.

2. There was one (1) TPDES wastewater discharge permit noncompliance in 2003. This noncompliance pertained to the release of fire protection water to Squaw Creek Reservoir. A written report of the release was submitted to the TCEQ on February 28, 2003, (TXX-03054) with a copy to the NRC.

There was no observed environmental impact to Squaw Creek Reservoir as a result of the release of approximately 8,000 to 9,000 gallons of fire protection water to this water body.
