LUMINANT POWER COMANCHE PEAK NUCLEAR POWER PLANT UNITS I & 2 2014 ANNUAL ENVIRONMENTAL OPERATING REPORT (NON-RADIOLOGICAL)
FACILITY OPERATING LICENSE NOs. NPF-87 & 89 I
I.
INTRODUCTION This report describes implementation of the Environmental Protection Plan (EPP) for the calendar year 2014 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 2014, the CPNPP Non-radiological Environmental Monitoring Program was effective in implementing and monitoring all CPNPP environmental regulatory commitments. Program effectiveness in 2014 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, including 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.
B.
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
- 2.
Annual Rainfall data 2
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 2014. Based on the results of these activities, there were no observed adverse environmental impacts resulting from plant operation during 2014.
- 1.
Groundwater Pumpage As indicated in Table 2, groundwater pumpage during 2014 averaged 0.0906 gals /min. (gpm) or 47600 total gallons withdrawn for the year. This withdrawal rate represents a 38% decrease from the 2013. This was due primarily to correcting a potable water leak associated with Rifle Range toilet. 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 2014 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 0.0906 gpm for 2014 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 0.6 % 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.
Since transfer to SCWD in January 2012, the combined annual rate for all recorded pre-operational groundwater pumpage averaged 68.8 gpm, while the average operational pumpage for the period 1990 through 2014 was 20.69 gpm. Therefore, the average operational rates are 70% less than the groundwater pumpage during the pre-operational period.
NOTE: Average operational pumpage for the period since transfer to SCWD (2012 thru 2014) was 0.48 gpm which is 99.3% less than the groundwater pumpage during the pre-operational period.
- 2.
Groundwater Levels As indicated in Table 1, the groundwater level in the on-site observation well OB-3 (intersection of Highway 56 and the Plant Access Road) fluctuated during 2014 from a low level in November of 603.22 ft. Mean Sea Level (MSL) to a high level in April of 607.94 ft. MSL. Overall, the water level in OB-3 during the reporting period (January through December) decreased 2.69 ft. = 0.82 m.
The 2014 annual average groundwater levels in wells OB-3 and OB-4 were 606.1 ft. MSL and 547.9 ft. MSL respectively.

- 3.
Surface Water Treatment System Operation The station's Water Treatment System processed 212,557,000 total gallons of surface water during 2014 for plant process use. No outages in 2014 that required reporting in accordance with Section 4.2.2 of the EPP.
The following is a summary list of monthly surface water usage:

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 2014. The following is a summary list of correspondence pertaining to netDMRs and TPDES permit related documents.

- 2. Bio-monitoring was on a semi-annual frequency in 2014. The first half sample was conducted in February and the second in July. All required test were passed satisfactorily for the two test performed in 2014. The previously mentioned agreement to allow usage of the 4-day Daphnia magna instead of Ceriodaphnia dubia when the TDS is above 2800 mg/L is now included in the permit.
- 3. There was one excursion in 2014 with reference to TPDES wastewater discharge permit. Excursion was pH related and documented on Condition Report 2014-013121. It occurred in December of 2014 and noted on associated netDMR for December (not reportable).
- 4. There were twenty-two (22) incidental spills in 2014 with none being reportable.

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.
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 2014 Radiological Environmental Report. (Reference TXX-1 5053) 6
