**Attachment B Documents Reviewed**1.0 Executive Summary

**The U.S. Environmental Protection Agency (EPA) con ducted an inspection of the**  **Department of Energy’s (DOE) Waste Isolation Pilot Plant (WIPP) from July 22 to July 24, 2008**  **as part of our continuing WIPP oversight program. The purpose of this inspection was to verify**  **that DOE continues to adequately monitor ten parame ters listed in the Compliance Certification**  **Application (CCA), Volume 1, Section 7.0, in partic ular Table 7-7 (See Table 1, COB-M2008-**  **1). Attachment A contains the inspection plan and the checklist used by the EPA inspector, and**  **Attachment B lists documents reviewed by the EPA.**

**The inspection examined the implementation of moni toring for geomechanical,**  **hydrological, waste activity, drilling related, and subsidence parameters. The EPA inspector**  **toured locations where measurements are taken, revi ewed parameter databases, and reviewed**  **documents and procedures directing these monitoring activities.** 

**The inspector found that DOE effectively implement ed the monitoring programs at WIPP**  **for all areas reviewed. EPA did not have any findi ngs or concerns. The inspector also**  **confirmed that the results of DOE monitoring progra ms are reported annually.** 

2.0 Scope

**The EPA WIPP Compliance Criteria (40 CFR Part 194. 42(a)) require DOE to “conduct**  **an analysis of the effects of disposal system param eters on the containment of waste in the**  **disposal system.” The results of these analyses we re included in the 1996 Compliance**  **Certification Application (CCA), confirmed in the 2 004 Compliance Recertification Application**  **(CRA), and were used to develop pre-closure and pos t-closure monitoring requirements.** 

**Volume 1, Section 7.0, of the CCA documented DOE’s analysis of monitoring**  **parameters. Table 7-7 of the CCA lists the ten par ameters that DOE determined may affect the**  **disposal system. These parameters are grouped into major categories and listed in Table 1. EPA**  **accepted these ten monitoring parameters in the 199 8 Certification Decision and confirmed them** 

**in the 2006 Recertification Decision.**

4.0 Performance of the Inspection

**The inspection began on Tuesday, July 22, 2008, wit h an opening meeting (COB-A2008-**  **S1a, -S1b) where changes in the parameter monitorin g programs since the previous inspection**  **were discussed by site staff (COB-M2008-I1 to -I8). On July 23, 2008 the inspection continued**  **with interviews and demonstrations of various aspec ts of each parameter monitoring area. On**  **July 24, 2008 the EPA inspector examined the databa se(s) used to store Delaware Basin**  **parameters and the WIPP Waste Information System (W WIS) waste computer database system.**  **The underground, where geomechanical measurements a re taken, was also inspected. The** **inspection closeout meeting was held on July 24, 20 08 in Carlsbad New Mexico (Sign-in sheet** 

**COB-A2008-S1a).**

**The EPA inspector reviewed three fundamental areas to verify continued implementation**  **of the DOE parameter monitoring program during the pre-closure phase: 1) written plans and**  **procedures, 2) quality assurance procedures and rec ords, and 3) results of the monitoring**  **program in the form of raw data, intermediate repor ts, and final annual reports, if appropriate.**  **The inspection checklist in Attachment A provides d etails of these inspection activities.** 

**The EPA inspector reviewed various activities to ve rify effective procedure**  **implementation. The inspector observed a demonstra tion of the WWIS and reviewed the**  **Delaware Basin Drilling Surveillance Program, Groun dwater Monitoring Program, and the**  **Geomechanical Monitoring Program.**

4.1 Monitoring of Geomechanical Parameters

**DOE committed to measure four geomechanical parame ters in the CCA: creep closure,**  **extent of deformation, initiation of brittle deform ation, and displacement of deformation features**  **(Table 2). WIPP has four programs that supply info rmation for these four parameters: the**  **geomechanical monitoring program, the geosciences p rogram, the ground control program, and**  **the rock mechanics program. These programs are doc umented in the WIPP Geotechnical**  **Engineering Program Plan, WP 07-01 (COB-M2008-E). The results of the geotechnical program**  **are reported in the Geotechnical Analysis Report fo r July 2006 - June 2007, DOE/WIPP-08-**  **3177, Volumes 1 and 2 (COB-M2008-A1 and -A2).**

**Geomechanical staff manually measured convergence values in the underground (Figure**  **1, Vertical Convergence Measurement) and the inspec tor examined the results documented in** **6**

**field data forms. After taking the measurements th e inspector observed staff inputting these data**  **into the computer database (COB-M2008-S42 to S49). The inspector found that procedures are**  **adequate for proper measurements: procedures are im plemented adequately; documents and field**  **data forms are controlled; and data is adequately c hecked, using check prints when necessary, to**  **assure adequate quality.**

4.2 Monitoring of Hydrological Parameters

**DOE committed to measure two hydrological paramete rs**  **in the CCA: Culebra groundwater composition and cha nges in the**  **Culebra groundwater flow direction. Related parame ters are** 
**measured and documented in the WIPP environmental monitoring program. These programs are documented**  **in the WIPP Groundwater Monitoring Program Plan, WP 02-1 (**  **COB M2008-C). Results of this program are documented i**  **n the WIPP Site Environmental Report for 2006, DOE/WIPP 07-222**  **5 (COB A2008-C). This document describes the groundwater**  **monitoring program and reports results for the previous year.** 

**During the 2008 inspection the EPA inspector reque sted**  **information about changes in the program since last year. The**  **opening meeting presentation noted that two new Cul ebra wells**  **were drilled and 2 wells were plugged since last ye ar (COB**  **M2008-I2a). The current well monitoring network c onsists of 47**  **Culebra, 11 Magenta, 3 dual Culebra/Magenta complet ions, 1**  **Dewey Lake, 2 Bell Canyon, and 20 shallow Santa Ros a/Dewey**  **Lake wells. Besides examining the Site Environment al Report**  **for 2006 the inspector examined flow direction maps , well**  **location maps, water level measurements, and water chemistry**  **data (COB-M2008-S24, -S40, -S41, and –S51) during t he 2008**  **inspection. The inspector found the hydrological m onitoring**  **program to be improving and adequate.**

4.3 Monitoring of Waste Activity Parameters

**DOE committed to monitor the activity of waste emp laced in the CCA. This parameter is**  **part of the extensive database collected for each c ontainer shipped to WIPP and is stored in the**  **WIPP Waste Information System (WWIS). The WWIS is a software system that screens waste**  **container data and provides reports on the Transura nic (TRU) waste sent to WIPP. The**  **requirements for the WWIS are discussed in the WIPP Waste Information System Program and**  **System Data Management Plan, WP 08-NT.01 (COB-M2008 -H2). DOE yearly reports waste**  **activity information in the Annual Change Report Ta ble 3 (DOE/WIPP 07-3317; COB-M2008-**  **Pa, -Pb). Vertical Convergence Measurement** **WWIS staff demonstrated that the WWIS can receive data and that the WWIS can** 

**generate needed reports. The inspector obtained co pies of the Nuclide Report (COB-M2008-**  **W1) and WWIS Shipment Summary Reports (COB-M2008-W2 and -W3). The inspector**  **verified that DOE tracks and annually reports the w aste activity at WIPP.** 

4.4 Monitoring of Drilling Related Parameters

**DOE committed to measure two drilling related para meters in the CCA: the drilling rate**  **and the probability of encountering a Castile brine reservoir. These parameters are measured as**  **part of the Delaware Basin Drilling Surveillance Pl an, WP 02-PC.02 (COB-M2008-G). This**  **surveillance program measures and records many para meters related to drilling activities around**  **the WIPP site. The results of the surveillance pro gram are documented annually in the Delaware**  **Basin Monitoring Annual Report, DOE/WIPP 07-2308 (COB-M2008-**  **M).**

**The inspector reviewed the drilling surveillance database,**  **examined drilling rate changes, and permitted and active injection wells**  **while interviewing staff. The inspector received and reviewed Texas** 

**and New Mexico well database ACCESS files and maps of oil and gas**  **wells around WIPP, (Figure 2, Oil and Gas Wells Around WIPP) (COB**  **M2008-D1 to -D3). The inspector verified that DOE tracks and reports**  **the drilling rate and the number of**

**Castile brine encounters near WIPP and reports results annually.** 

4.5 Monitoring of Subsidence Parameters

**DOE committed to measure subsidence at the WIPP si te. This parameter is documented**  **as part of the WIPP Underground and Surface Surveyi ng Program, WP 09-ES.01 (COB-M2008-**  **B). DOE performs subsidence surveys at the site an nually during pre-closure operations. The**  **results of this program are reported annually in th e WIPP Subsidence Monument Leveling**  **Survey – 2007, DOE/WIPP 08-2293 (COB-M2008-F).**

**Subsidence staff demonstrated the Office Procedure (Section 2 of WP 09-ES4001: COB**  **M2008-N) to the EPA inspector which describes the s teps taken to process raw field survey data**  **and to calculate final surface elevations published in their annual report (COB-M2008-S62 to -**  **S64). The inspector examined the procedure, Subsid ence Software Installation and Checkout**  **Oil and Gas Wells Around WIPP (Red Dots) 8** 

**Form/Report (COB-M2008-S60), used to qualify comput er software to support the subsidence**  **program. The inspector confirmed that the computer code is qualified appropriately using hand**  **calculations (COB-M2008-S61). DOE demonstrated tha t the subsidence parameter is measured**  **and reported yearly.**

5.0 Summary of finding, observation, concerns, and recommendations.

**Based on program documents, interviews, and field demonstrations during the inspection,**  **EPA concludes that the monitoring program covers th e ten monitoring parameters required by**  **EPA’s 1998 Certification Decision. This inspection determined that the monitoring, sample**  **collection, and sample/data analysis procedures wer e complete and appropriate; that staff were**  **adequately trained and implemented the procedures a dequately; and that appropriate quality**  **assurance measures are applied. EPA continues to f ind that DOE has maintained adequate**  **parameter monitoring during the past year and has t he procedures and requirements in place to**  **sustain their program into the next year. EPA has no findings or concerns.**
