Appendix DATA-2014 provides references to the data used to develop the Compliance Recertification Application (CRA) of 2014 (CRA-2014). Interpretation and analysis of those data are provided in the appropriate sections of the CRA-2014.

Title 40 CFR § 194.15(a)(1), (2), (3), and (5) (U.S. EPA 1996), Content of Recertification Applications, require that the U.S. Department of Energy (DOE) provide information obtained since the Compliance Certification Application (CCA) (U.S. DOE 1996) related to site geology, hydrology, and meteorology. Additional monitoring results and the results of laboratory investigations completed after the CRA-2009 (U.S. DOE 2009a) must also be provided, as well as information regarding the waste emplaced in the disposal system.

The DOE uses various programs to capture and analyze relevant information. These programs and the resulting information are discussed in the appropriate sections of this appendix.

In the initial U.S. Environmental Protection Agency (EPA) certification of compliance for the Waste Isolation Pilot Plant (WIPP) (U.S. EPA 1998), the EPA agreed that 10 compliance monitoring parameters (COMPs) would be monitored during the operational period of the project. Monitoring is performed to detect substantial deviations from expected conditions in the WIPP performance assessment (PA). The locations of the data for the COMPs in this appendix are listed below:

The Delaware Basin Drilling Surveillance Program (DBDSP) monitors drilling activities in the Delaware Basin. This section provides a brief discussion of the program and identifies the relevant data reports.

The EPA requires the DOE to demonstrate the expected containment performance of the disposal system using a PA. The PAs documented in the CCA, CRA-2004 (U.S. DOE 2004), CRA-2009, and CRA-2014 demonstrated that the DOE complies with the EPA's containment standards for undisturbed and human intrusion scenarios.

The criteria in 40 CFR § 194.33 (U.S. EPA 1996) require the use of historic drilling information to derive the drilling rate for PA intrusion scenarios. The DBDSP continues to monitor drilling-related activities, providing data used to determine whether the assumptions and scenarios used in PA remain valid, and uses the monitoring data to determine the drilling rate. These monitoring activities will continue until the DOE and the EPA agree that no additional benefit can be gained by further monitoring.

The two COMP parameters monitored by the DBDSP are the drilling rate (67.3 boreholes per square kilometer) (U.S. DOE 2012a) and the probability of encountering a Castile brine reservoir (4.5%) (Callicoat 2013a), which are discussed in the annual reports for this program and also in the COMPs assessments described in Section DATA-10.0. Other information collected by this program include drilling-related data, mining information, and seismic information.

Relevant data generated through the Delaware Basin Monitoring Program are provided in the following reports published since the CRA-2009:

Subsidence monitoring measures vertical movement of the land surface relative to a reference location. This section provides a brief discussion of the Subsidence Monitoring Program (SMP) and identifies the relevant data reports.

The SMP uses a leveling survey to measure the relative vertical height differences between benchmarks. A level survey consists of using one benchmark's elevation as a constant elevation and determining the elevation of all other benchmarks relative to it. Comparison between level surveys allows vertical movement patterns to be established over time. These comparative surveys allow substantial deviation of actual subsidence from expected subsidence to be detected.

Each year approximately 15 miles of leveling surveying is completed utilizing nine vertical control loops consisting of 48 subsidence monuments and 14 National Geodetic Survey vertical control points. Subsidence rates are small and are approximately at the resolution level of the survey accuracy. The benchmarks with the highest rates are seen above the mined panels. All subsidence rates fall within the predicted values. Data generated through the SMP are provided in the following reports published since the CRA-2009. Each report includes previous years' data.

The Geotechnical Monitoring Program (GMP) measures in situ geotechnical data in the WIPP repository. This section provides a brief discussion of the GMP and identifies the relevant data reports.

The GMP obtains in situ data to support the continuous assessment of underground facilities. A detailed description of the geotechnical programs and procedures is presented in WP 07-1, WIPP Geotechnical Engineering Program Plan (Nuclear Waste Partnership 2012). Specifically, the program provides for

· Early detection of conditions that could affect operational safety

· Guidance for design modifications and remedial actions

· Data for interpreting the behavior of underground openings compared to established design criteria

The GMP collects data through instrumentation and observation. These data are used to confirm the understanding of geomechanical characteristics and aid in assessing the stability and performance of the underground facility. Constituent programs, described below, include the Geosciences Program, the Geomechanical Monitoring Program, and the Rock Mechanics Program.

The Geosciences Program includes the collection of underground data used to assess the repository by documenting the existing geologic conditions and characteristics and monitoring excavation response. Activities associated with this program include geologic and fracture mapping of the excavation surface, core logging, and borehole observations.

The Geomechanical Monitoring Program includes monitoring the geomechanical response of the underground openings after mining using instrumentation installed in the shafts and drifts of the facility. Geotechnical instrumentation installed underground in the shafts and drifts includes tape extensometer points, convergence meters, borehole extensometers, piezometers, strain gauges, load cells, and crack meters. The instrumentation is sensitive enough to detect small changes in rock displacements and stresses.

To determine significant deviations from expected conditions, the Management and Operating Contractor uses the Rock Mechanics Program to assess the performance of the underground excavation for safety and stability during the operational phase. The results from these assessments allow the identification of potentially unstable areas and the application of remedial actions, if necessary. Field data are used to compare the actual mechanical performance of the excavations to expected results. Analytical methods, such as numerical modeling, determine the potential effects of mining new excavations, excavation sequence, and long-term behavior of the repository. Extensive experimental work and observations have established an understanding of time-dependent geomechanical properties of the salt that are used to predict its in situ mechanical performance. These assessments rely heavily on the in situ instrumentation data and field observations from the Geoscience and Geomechanical Monitoring Programs.

Data generated through the GMP are reported annually in the Geotechnical Analysis Report. References for reports prepared since the development of the CRA-2009 are provided below. Each report includes previous years' data. Four parameters, relating to information collected by the GMP, are required to be monitored by the DOE. These are creep closure, extent of deformation, initiation of brittle deformation, and displacement of deformation features. Creep closure and displacement of deformation features are quantitative. Extent of deformation and initiation of brittle deformation are qualitative. These four parameters are discussed and analyzed in the COMPs reports listed in Section DATA-10.2.

The Groundwater Monitoring Program (GWMP) collects and analyzes data for various wells at or near the WIPP site. This section briefly describes the GWMP and identifies relevant reports.

One function of the GWMP is the collection of groundwater data from the Culebra Dolomite Member of the Rustler Formation (hereafter referred to as the Culebra), such as water levels and water quality, from numerous wells located at and near the facility. The Culebra was selected as the focus of the GWMP. It has been extensively studied during past hydrologic characterization programs and was found to be the most likely hydrologic pathway to the accessible environment for any potential human-intrusion-caused release scenario. Data obtained through this program are used to generate the Culebra groundwater composition and the Culebra groundwater flow COMPs. Details on how the program is implemented are provided in Appendix MON-2014.

The water quality data collected by the GWMP are discussed and analyzed in the reports listed below and also in the COMPs reports listed in Section DATA-10.2. This analysis provides validation of the various Culebra hydrological models for CRA-2014. Appendix HYDRO-2014 and the COMPs reports provide analyses of the water levels and the fluid density of the water columns in the various wells used in gathering data for the WIPP hydrological model. The following reports have been published since the CRA-2009:

The Meteorological Monitoring Program measures atmospheric data for the WIPP site. This section provides a brief description of the program and relevant reports.

The primary WIPP meteorological station is located 600.5 meters (m) (1,970 feet (ft)) northeast of the Waste Handling Building. The main function of the station is to provide data for atmospheric modeling. The station measures and records wind speed, wind direction, and temperature at elevations of 2, 10, and 50 m (6.5, 33, and 165 ft). The station records ground-level measurements of barometric pressure, relative humidity, precipitation, and solar radiation.

The annual site environmental reports listed in Section DATA-5.2 provide data relevant to the Meteorological Monitoring Program. The CCA, Appendix CLI provides information on past (long-term) climatic conditions and predicted future conditions at the WIPP site. A discussion of the wind, rainfall, and temperature variation can be found in CRA-2014, Section 15.


Two types of information related to waste characteristics are collected: (1) information regarding waste that has been emplaced in the WIPP underground repository, and (2) information regarding future inventory that will be emplaced in the WIPP underground repository during the entire lifetime of the project. This section provides a brief description of the programs and a list of relevant reports.

Information concerning waste that has been emplaced in the repository is tracked and recorded using the Waste Data System (WDS), formerly the WIPP Waste Information System. Information concerning future wastes to be emplaced in the WIPP is developed through periodic updates of the Annual Transuranic Waste Inventory Reports. The inventory for the CRA-2014 PA is from the Performance Assessment Inventory Report -2012 (Van Soest 2012) based on the Annual Transuranic Waste Inventory Report-2012 (U.S. DOE 2012e), that provides updated inventory information. The DOE anticipates that these inventory updates will have only a small impact on normalized releases relative to the CRA-2014 PA, and therefore have no significant impact on compliance.

Summary information generated by the WDS on emplaced waste and radionuclides is provided in the following reports published since the CRA-2009. See page 21 of the Annual Change Report 2011/2012, DOE/WIPP-12-3496 (U.S. DOE 2012f) for a detailed listing of the emplaced waste in the repository.

Information regarding WIPP monitoring wells is identified in this section, and relevant data are provided.

Information provided in this section was reported in DOE/WIPP 95-2092, Revision 1, Waste Isolation Pilot Plant Borehole Data Report (the CCA, Appendix BH). The CCA, Appendix BH serves as a central document providing data on boreholes. The report contains a comprehensive database of wells drilled in support of the WIPP Project and boreholes that were located within the 16-section land withdrawal area.

Attachment A to this appendix provides updates on all of the monitoring wells used in the CCA, Appendix BH, and the new monitoring wells drilled since the initial certification. The attachment also adds wells that were in use, but inadvertently omitted from the CCA, Appendix BH. There were 6 wells drilled and 7 wells plugged during the CRA-2014 monitoring period from October 1, 2007, through December 31, 2012.


The WIPP Repository Investigations Program conducts research activities to confirm assumptions, reduce uncertainty, and resolve issues regarding the conceptual models and parameters used in PA. The program is briefly described in this section and references to relevant reports are provided.

The DOE has implemented and/or continued several experimental activities designed to address specific issues and needs of the WIPP repository. In addition, other investigations have been initiated to examine impacts of planned changes. The general areas covered under these investigations include

· Geochemistry

· Actinide chemistry

· Engineered barriers

· Rock mechanics (Sandia National Laboratories)

Data acquired by the DOE from the repository investigations are available in the following reports, publications, and technical memoranda published since the CRA-2009.

Annually, the Compliance Monitoring Program (CMP) extracts data from the repository investigations and five of the monitoring programs described above (DBDSP, SMP, GMP, GWMP, and WDS) to derive values for the 10 COMPs described in Section DATA-1.0 and to evaluate whether significant changes in the parameters have occurred. The CMP activities are briefly described in this section. Data generated under the CMP are also identified.

The objective of the CMP is to provide assurance that any deviations from the expected long-term performance of the repository are identified at the earliest possible time. The CMP is implemented in accordance with DOE/WIPP 99-3119, Compliance Monitoring Implementation Plan for 40 CFR §191.14(b), Assurance Requirement (U.S. DOE 2012i). Annual evaluations of the compliance parameters follow the requirements found in Sandia National Laboratories SP 9-8, Monitoring Parameter Assessment Per 40 CFR 194.42, Revision 1 (Wagner 2011).

The data and the results of the annual COMPs assessments performed in accordance with the requirements of the CMP are provided in the following reports published since the CRA-2009. There are no COMPs data or results that indicate a reportable event or condition adverse to predicted performance.

The Exhaust Shaft Hydraulic Assessment, now the Shallow Subsurface Water Investigation, was initiated in September 1996 to investigate the source and extent of water seepage into the exhaust shaft at the WIPP. An investigation of rising water levels in the Culebra was initiated in 1999. These hydrologic investigations are briefly described in this section. Sources of data generated from the investigations are also identified.

Investigations of water entering the exhaust shaft led to the observation of a shallow perched groundwater horizon in a saturated layer within the lower Santa Rosa Formation and the upper Dewey Lake Redbeds Formation, about 15 m (49 ft) below ground surface. During the original drilling and geological mapping of the shaft, no water was encountered at that horizon, indicating that the presence of water may be related to site activities subsequent to shaft drilling. Three wells and 12 piezometers were installed over an 80-acre area between September 1996 and July 1997 (INTERA 1997). In 2007, three more piezometers were installed. No new piezometers have been installed since 2007. Water-level and water-quality parameters continue to be monitored and reported on a regular basis.

During the 1999 annual COMPs assessment, Culebra water levels in many of the WIPP monitoring wells exceeded the CCA ranges of uncertainty established for equilibrium freshwater heads to calibrate transmissivity fields needed for Culebra flow and transport calculations. Culebra water-level rises had also been observed at the time of the CCA submittal in 1996 but were attributed to natural recovery of water levels following years of hydraulic well testing at the WIPP site and grouting of the WIPP shafts. Subsequent to the 1999 COMPs assessment, Culebra water levels showed a continued rise even though water levels at the WIPP site were thought to have fully recovered from hydraulic testing and shaft grouting. In response to this observation, the DOE initiated an investigation into the cause of the water-level rise and the impact of the rise on the long-term performance of the WIPP, which is discussed in Appendix HYDRO-2009 and Appendix HYDRO-2014. Culebra water-level rises peaked around 2008 and have shown a continuing gradual decline since that time.

Data acquired from the two hydrologic investigations are provided in the reports cited below for the Shallow Subsurface Water Investigation and the Culebra water-level rise investigation.

The Geotechnical Analysis Reports listed in Section DATA-4.2 provide data relevant to the Shallow Subsurface Water Investigation. Additional detailed information on this subject is contained in "Hydrologic Assessment of Shallow Subsurface Water" (Daniel B. Stephens & Associates, Inc. 2008), and "Assessment of Lead in PZ-13 Near the Site and Preliminary Design Validation (SPDV) Pile at Waste Isolation Pilot Plant" (Daniel B. Stephens & Associates, Inc. 2010).
