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 10 to July 12,**  **2007, as part of our continuing WIPP oversight prog ram. The purpose of this inspection was to**  **verify that DOE continues to adequately monitor ten parameters listed in the Compliance**  **Certification Application (CCA), Volume 1, Section 7.0, in particular Table 7-7 (See Table 1,**  **COB-M2006-1). Attachment A contains the checklist and the inspection plan used by the EPA**  **inspector, and Attachment B lists documents reviewe d by the EPA inspector.** 

**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, through its contract or Washington TRU Solutions (WTS),**  **effectively implemented the monitoring programs at WIPP for all areas. EPA did not have any**  **findings or concerns. The inspector also confirmed that the results of DOE monitoring programs**  **are reported annually.**

2.0 Scope

**The WIPP Compliance Criteria (40 CFR Part 194.42(a )) require DOE to “conduct an**  **analysis of the effects of disposal system paramete rs on the containment of waste in the disposal**  **system.” The results of these analyses were includ ed in the 1996 Compliance Certification**  **Application (CCA), confirmed in the 2004 Compliance Recertification Application (CRA), and**  **were used to develop pre-closure and post-closure m onitoring 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 th e 1998 Certification Decision and** 

**confirmed them in the 2006 Recertification Decision . This inspection was performed under**  **authority of 40 CFR 194.21, which authorizes EPA to verify the continued effectiveness of the**  **parameter monitoring program at WIPP. Inspection a ctivities included an examination of**  **monitoring and sampling equipment both on and off s ite, and in the underground. EPA also**  **reviewed numerous sampling procedures and measureme nt techniques and verified**  **implementation of an effective quality assurance pr ogram (see the document list in Attachment**  **B).**

4.0 Performance of the Inspection

**The inspection began on Tuesday, July 10, 2007, wit h an opening meeting (COB-A2007-**  **S2) where changes in the parameter monitoring progr ams since the previous inspection were**  **discussed by site staff (COB-M2007-I4a to –I4g). O n July 11, 2007 the inspection continued**  **with interviews and demonstrations of various aspec ts of each parameter monitoring area. On**  **July 12, 2007 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.** **3**

**The underground, where geomechanical measurements a re taken, was also inspected. The**  **inspection closeout meeting was held on July 12, 20 07 in Carlsbad New Mexico (COB-A2007-**  **S2b).**

**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-M2007-C). The results of the geotechnical**  **program are reported in the Geotechnical Analysis R eport for July 2005 - June 2006,**  **DOE/WIPP-07-3177, Volumes 1 and 2 (COB-M2007-A and -A2).**

**The EPA focused on geomechancial monitoring parame ters during this inspection, in**  **particular values that are measured manually – such as convergence points, observation**  **boreholes, mapping of roof fractures, and stratigraphic mapping (see Table 2). These** 

**manual measurements are used to track and confirm long-term performance of these four**  **monitor parameters. The inspector, before the inspection, selected measurements points (COB**  **M2007-G8) in Room 1 of Panel 4: convergence points – roof to floor, E520-S3480-2 A-C and wall**  **to wall, E520-S3480 B-D (COB-M2007-G1,-G5); observation borehole, OH 530 (COB-M2007-G2,-**  **G11,-G12,-G13, scratch rod measurement-Figure 1); roof fracture mapping in Room 1 Panel 4**  **(COB-M2007-G7a,-G7b,-G7c); and, mapping of stratigraphy in Room 1 Panel 4 (COB-M2007-G9,**  **stratigraphy mapping-Figure 2). A remote measured extensometer (51X-GE-00376) point**  **was also selected for review (COB-M2007-G10).**

**Geomechanical staff manually measured these values while the inspector observed**  **implementation of procedures and examined the resul ts documented in field data forms or plots.**  **After taking the measurements the inspector observe d staff inputting these data into the computer**  **database (COB-M2007-G14). The inspector found that procedures are adequate for proper**  **measurements: procedures are implemented adequately; documents and field data forms are**  **controlled; and, data is adequately checked, using check prints when necessary, to assure**  **adequate quality.**

4.2 Monitoring of Hydrological Parameters

**DOE committed to measure two hydrological parameters in the CCA: Culebra**  **groundwater composition and changes in the Culebra groundwater flow direction. Related parame**  **ters are measured and documented in the WIPP environmental monitoring program. These progr**  **ams are documented in the WIPP Groundwater Monitoring Program Plan, WP 02-1 (COB-M**  **2007-B). Results of this program are**

**documented in the Waste Isolation Pilot Plant Site Environmental Report for 2005, DOE/WIPP**  **06-2225 (COB-M2007-I). This document describes the groundwater monitoring program and**  **reports results for the previous year. Figure 1 Scratch Rod Measurement** 

**Figure 2 Stratigraphy Mapping 5** 

**During the 2007 inspection the EPA inspector reque sted information about changes in the**  **program since last year. The opening meeting prese ntation noted that five new Culebra wells**  **were drilled and 4 wells plugged since last year (C OB-M2007-I4b). The current well**  **monitoring network consists of 45 Culebra, 10 Magen ta, 5 dual Culebra/Magenta completions, 1**  **Dewey Lake, 2 Bell Canyon, and 17 shallow Santa Ros a/Dewey Lake wells. Besides examining**  **the Site Environmental Report for 2005 the inspecto r examined flow direction maps, well**  **location maps, water level measurements, and water chemistry data and plots (COB-M2007-H1,**  **-H1a, -H1b, -H2, -H3, -H4, -H5, -H6, -H7a, -H7b, -H 8, -H10, -H16, -H19, and -H20) during the**  **2007 inspection. The inspector found the hydrologi cal monitoring 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-M2007 -E). DOE yearly reports waste**  **activity information in the Annual Change Report Ta ble 3 (DOE/WIPP 06-3177; COB-M2007-**  **K).**

**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-M2007-**  **W1), WWIS Shipment Summary Reports (COB-M2007-W2 an d -W3) and WWIS Waste**  **Container Data Reports (COB-M2007-W4, -W5, -W6, and -W7). The inspector verified that**  **DOE tracks and annually reports the waste 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-M2006-F). 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 06-2308 (C OB-M2007-H).** 

**The inspector reviewed the drilling surveillance d atabase, examined drilling rate changes,**  **and permitted and active injection wells while inte rviewing staff. The inspector received and** 

**reviewed Texas and New Mexico well database ACCESS files, maps of oil and gas wells around**  **WIPP, and well plugging documents. (COB-M2007-H12, -H13, -H15, -H17, -H18, -H21, -H22,**  **-H22a, -H22b, and -H23). The inspector verified th at DOE tracks and reports the drilling rate** 

**and the number of Castile brine encounters near WIP P.** **6**

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-M2006-**  **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 – 2006, DOE/WIPP 07-2293 (COB-M2007-D).**

**Subsidence staff demonstrated the Office Procedure (Section 2 of WP 09-ES4001 (COB**  **M2006-P)) to the EPA inspector which describes the steps taken to process raw field survey data**  **and to calculate final surface elevations published in their annual report (COB-M2007-S1, -S2, -**  **S3, -S4, and –S5). DOE demonstrated that the subsi dence 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. For these reasons, EPA continues to find that DOE has**  **maintained adequate parameter monitoring during the past year and has the procedures and**  **requirements in place to sustain their program into the next year. EPA has no findings or** 

**concerns. 7**
