TV ELECTRIC COMANCHE PEAK STEAM ELECTRIC STATION UNIT 1 1990 ANNUAL ENVIRONMENT AL OPERATING REPORT (NONRAD10 LOGICAL)

, Attachment to VXX 93163 Page 2 of 7

1. INTRODUCTION This annual environmental operating report describes implementation of the Environmental Protection Plan (EPP) as required by Appendix B to the Unit 1 Facility Operating License NPF 87. The EPP requires that this report cover the operational period from the date of issuance of Unit 1 low power operating license (February 8,1990) through December 31, 1990.

4 However, to facilitate data reduction and comparison, this report also includes January with the actual operational months of 1990.

11. SCOPE Section 5.4.1 of the EPP requires that Comanche Peak Steam Electric Station (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 cbserved impacts of plant operation on the environment. If harmful effect or evidence of trends towards irreversible damage to the environment are observed, a detailed analysis of the data and a nroposed 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 corrective actions taken to remedy them.

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

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

4. A summary list of-National Pollutant Discharge Elimination System (NPDES) permit related reports relative to matters identified in Subsection 2.1 which were sent to the EPA Region VI during the report period. Subsection 2.1 of the EPP pertains to-aquatic matters that are addressed by the effluent limitations, monitoring requirements and the Section 316(b) demonstration requirement (effects of intake structure on aquatic biota during operation) contained in the EPA NPDES station wastewater l discharge permit.

1. Groundwater Pumpage As indicated in Table 1. groundwater pumpage during 1990 averaged 27.8 gals / min or 14.598.400 total gallons withdrawn for the year.

This rate represent 22% of the predicted operational pumpage (127 gals / min) identified in the station's Environmental Report -

Operating License Stage (Section 3.3) and 17.6% of the actual average withdrawal : ate (158 gols/ min) reported in the station's Final Environmental Statement Operating Licensing Stage (Section 5.3.1.2) for the period 1975 to May 1979.

Table 2 provides the annual well pumpage rates for the period 1987 through 1989 as well as 1990. This data supplements the preoperational cata previously reported to the NRC in Attachment 1 to TV Electric correspondence logged TXX-6677, dated September 6. 1987. The combined annual rate for all recorded preoperational groundwater pumpage averaged 68.8 gals / min.

Therefore the operational rates recorded for 1990 are 59% lower than the groundwater pumpage from recorded preoperational annual pumpage rates.

All groundwater withdrawn during 1990 was used for potable and sanitary purposes only and no groundwater was used to supplement the station's Surface Water Treatment System for plant make up.

The surface Water Treatment System provided 1.075.600 gols of treated water for potable use during 1990 to supplement the on-site groundwater production wells.

2. Groundwater Levels As indicated in Table 3. the groundwater levels during 1990 in Observation Wells 0B 3 and 08 4 increased 1.00 ft and 0.50 ft, respectively. The overall groundwater level change during the period September 1987 through December 1989 is included in Table

3. This data supplements the preoperational data previously reported to the NRC in Attachment 1 to TU Electric correspondence logged TXX-6677, dated September 6. 1987.

3. Surface Water Treatment System Operation The station's Surface Water Pretreatment System processed 31.767.974 total gallons for station make up water use during 1990. This represents an annual average flow to the plant demineralizers, including Vendor supplied demineralizers. of 60.1 gals / min. There were no outages during 1990 that required reporting in accordance with Section 4.2.2.

. Attachaent to TXX 91163 Page 4 of 7 B. 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 or operation, nor 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 There were no nonroutine reports submitted under this subsection.

E. NPDES Permit Related Reports Relative To Matters identified In Subsection 2.1 Routine monthly Discharge Monitoring Reports (DMR) for all waste water outfall were submitted to the EPA and state agencies for each month during 1990. The following is a summary list of correspondence submitted to the EPA relating to these DMRs.

Month Honitotid (9.glygbe r/Dat e January TXX 90078/2 23 90 i February TXX 90116/3 23 90 March TXX 90166/4 25 90 April TXX 90196/5 25 90 May TXX 90234/6 25 90 June TXX 90266/7 25 90 July TXX 90308/8 24 90 August TXX 90351/9 25 90 September TXX 901006/10 25 90 October TXX 901038/11 21 90 November TXX 901065/12 21 90 December TXX 91041/1 25 91 There was one waste water permit non-compliance reported during 1990.

This non compliance resulted when the two hour chlorination limit was exceeded for the circulating water system (Outfall 201).

A verbal notification was also made to the state agency (Texas Water Commission) on October 24, 1990, concerning an overflow of a sewage lift station. This incident was also verbally reported to the NRC on October 24, 1990. A written notification (TXX 88706, cross reference TXX 91009) was submitted to the Texas Water Commission on October 29, 1990.
