I.
INTRODUCTION This report describes implementation of the Environmental Protection Plan (EPP) for the calendar year 2016 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 2016, the CPNPP Non-radiological Environmental Monitoring Program was effective in implementing and monitoring all CPNPP environmental regulatory commitments. Program effectiveness in 2016 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.

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 2016. Based on the results of these activities, there were no observed adverse environmental impacts resulting from plant operation during 2016.
- 1.
Groundwater Pumpage As indicated in Table 2, groundwater pumpage during 2016 averaged 0.098 gals /min. (gpm) or 51500 total gallons withdrawn for the year. This withdrawal rate represents a 28% decrease from the 2015. 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 2016 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 0.098 gpm for 2016 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 in 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 2016 from a low level in January of 610. 77 ft. Mean Sea Level (MSL) to a high level in December of 617.98 ft. MSL. Overall, the water level in 08-3 during the reporting period (January through December) increased 7.21 ft. = 2.20 m The 2016 annual average groundwater levels in wells 08-3 and 08-4 were 616.09 ft. MSL and 555.07 ft. MSL respectively.

Surface Water Treatment System Operation The station's Water Treatment System processed 183,455,000 total gallons of surface water during 2016 for plant process use. No outages in 2016 that required reporting in accordance with Section 4.2.2 of the EPP.
The following. is a summary list of monthly surface water usage:
