  • ANNUAL ENVIRONMENTAL OPERATING REPORT (NON-RADIOLOGICAL)

FACILITY OPERATING LICENSE NOs. NPF-87 & 89

I. INTRODUCTION This report describes implementation of the Environmental Protection Plan (EPP) for the calendar year 2015 as required by Appendix B to Facility Operating License Nos. NPF-87 & 89 for Comanche Peak Nuclear Power Plant (CPNPP) for Units 1 & 2.

During 2015, the CPNPP Non-radiological Environmental Monitoring Program was effective in implementing and monitoring all CPNPP environmental regulatory commitments. Program effectiveness in 2015 was substantiated by Luminant Corporate environmental audits and compliance evaluations of the CPNPP Environmental program.

II. SCOPE Section 5.4.1 of the EPP requires that CPNPP 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, induding a comparison with related preoperational studies, operational controls (as appropriate), and previous non-radiological 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 actions are 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.
8. The report shall also include:
1. A list of EPP non-compliances 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 non-routine 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.

C. Additional information added but not required:

1. Squaw Creek Reservoir (SCR) make-up and release data (Figure 3)
2. Annual Rainfall data (Figure 4) 2

111. 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 2015. Based on the results of these activities, there were no observed adverse environmental impacts resulting from plant operation during 2015.

1. Groundwater Pumpage As indicated in Table 2, groundwater pumpage during 2015 averaged 0.137 gals /min. (gpm) or 71900 total gallons withdrawn for the year. This withdrawal rate represents a 51 % increase from the 2014. This was due to adding the recreation area restrooms to the system. CPNPP continues to be supplied by Somervell County Water District (SCWD) which started in January 2012.

Groundwater withdrawal dropped to <1 gpm after Somervell County Water District (SCWD) became our supplier.

Groundwater withdrawn during 2015 was used primarily for potable and sanitary purposes. No groundwater was used to supplement the station's Surface Water Treatment System.

The average annual pumpage rate of 0.137 gpm for 2015 represents <1 % 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 0.1 % of the actual average withdrawal rate (158 gpm) reported ih the Station's Final Environmental Statement - Operating License Stage (Section 5.3.1.2) for the period 1975 to May 1979.

2. Groundwater Levels As indicated in Table 1, the groundwater level in the on-site observation well 08-3 (intersection of Highway 56 and the Plant Access Road) fluctuated during 2015 from a low level in September of 603.78 ft. Mean Sea Level (MSL) to a high level in June of 611.76 ft. MSL. Overall, the water level in 08-3 during the reporting period (January through December) increased 3.57 ft. = 1.09 m The 2015 annual average groundwater levels in wells OB-3 and OB-4 were 608.07 ft. MSL and 549.02 ft. MSL respectively.

3

3. Surface Water Treatment System Operation The station's Water Treatment System processed 202,445,000 total gallons of surface water during 2015 for plant process use. No outages in 2015 that required reporting in accordance with Section 4.2.2 of the EPP.

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

I Month I Gallons Clarified I January 14,790,000 February 14,187,000 March 15,520,000 April 17,397,000 May 17, 172,000 June 16,405,000 July 18,715,000 AUQUSt 18,715,000 September 17,473,000 October 18,222,000 November 16,554,000 December 17,295,000 Total annual production 202,445,000 B. EPP Noncompliance and Corrective Actions - Subsection 5.4.1(1)

There were no non-compliances 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. Non-routine Reports Submitted In Accordance With Subsection 5.4.2 None 4

E. Texas Pollutant Discharge Elimination System (TPDES) Permit-Related Reports Relative to Matters Identified In Subsections 2.1 and 5.4.1

1. Routine monthly electronic Discharge Monitoring Reports (netDMR) for all wastewater outfalls were submitted to the Texas Commission on Environmental Quality (TCEQ) for each month during 2015. The following is a summary list of correspondence pertaining to netDMRs and TPDES permit related documents.

Month Monitored Log Number/Date January TXE-15031 02/20/2015 February TXE-15048 03/20/2015 March TXE-15070 04/20/2015 April TXE-15080 05/20/2015 May TXE-15097 06/19/2015 TXE-15109 07/20/2015 June TXE-15110 07/20/2015 (Bio-monitorinq Reoort)

2. Bio-monitoring was on a semi-annual frequency in 2015. The first half sample was conducted in February and the second in October. All required test were passed satisfactorily for the two test performed in 2015.
3. There were no excursions in 2015 with reference to TPDES wastewater discharge permit.
4. There were fift~en (15) incidental spills in 2015 with none being reportable.

Petroleum - 11, Sewage - 3, Chemical - 1 and Process Water - 0 F. Environmental maintains Squaw Creek Reservoir (SCR) for the primary purpose of providing quality cooling water for CPNPP and managing SCR water inventory within operational guidelines for both make-up and release. A secondary function is to minimize removal rate from Lake Granbury during periods of drought or when water conservation measures implemented by the State.

5

Figures 3 and 4 provide historical data related to SCR net water released and associated rainfall.

Additionally, the overall net make-up and release has an impact on the tritium (H3) concentration in SCR. Taking into account environmental factors, operating SCR at a lower level (between 774' and 775' mean sea level (MSL)) versus at greater than or equal to 775.08' with release over spillway has slightly increased the tritium concentration in SCR. However, this slight increase fluctuates and is basically negligible.

The description of the monitoring and evaluation of tritium impact to Members of the Public is contained in CPNPP 2015 Radiological Environmental Report.

I. INTRODUCTION This report describes implementation of the Environmental Protection Plan (EPP) for the calendar year 2015 as required by Appendix B to Facility Operating License Nos. NPF-87 & 89 for Comanche Peak Nuclear Power Plant (CPNPP) for Units 1 & 2.

During 2015, the CPNPP Non-radiological Environmental Monitoring Program was effective in implementing and monitoring all CPNPP environmental regulatory commitments. Program effectiveness in 2015 was substantiated by Luminant Corporate environmental audits and compliance evaluations of the CPNPP Environmental program.

II. SCOPE Section 5.4.1 of the EPP requires that CPNPP 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, induding a comparison with related preoperational studies, operational controls (as appropriate), and previous non-radiological 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 actions are 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.
8. The report shall also include:
1. A list of EPP non-compliances 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 non-routine 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.

C. Additional information added but not required:

1. Squaw Creek Reservoir (SCR) make-up and release data (Figure 3)
2. Annual Rainfall data (Figure 4) 2

111. 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 2015. Based on the results of these activities, there were no observed adverse environmental impacts resulting from plant operation during 2015.

1. Groundwater Pumpage As indicated in Table 2, groundwater pumpage during 2015 averaged 0.137 gals /min. (gpm) or 71900 total gallons withdrawn for the year. This withdrawal rate represents a 51 % increase from the 2014. This was due to adding the recreation area restrooms to the system. CPNPP continues to be supplied by Somervell County Water District (SCWD) which started in January 2012.

Groundwater withdrawal dropped to <1 gpm after Somervell County Water District (SCWD) became our supplier.

Groundwater withdrawn during 2015 was used primarily for potable and sanitary purposes. No groundwater was used to supplement the station's Surface Water Treatment System.

The average annual pumpage rate of 0.137 gpm for 2015 represents <1 % 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 0.1 % of the actual average withdrawal rate (158 gpm) reported ih the Station's Final Environmental Statement - Operating License Stage (Section 5.3.1.2) for the period 1975 to May 1979.

2. Groundwater Levels As indicated in Table 1, the groundwater level in the on-site observation well 08-3 (intersection of Highway 56 and the Plant Access Road) fluctuated during 2015 from a low level in September of 603.78 ft. Mean Sea Level (MSL) to a high level in June of 611.76 ft. MSL. Overall, the water level in 08-3 during the reporting period (January through December) increased 3.57 ft. = 1.09 m The 2015 annual average groundwater levels in wells OB-3 and OB-4 were 608.07 ft. MSL and 549.02 ft. MSL respectively.
