1.0 EXECUTIVE SUMMARY 

 The U.S. Environmental Protection Agency (EPA or the Agency) conducted an inspection of the 

U.S. Department of Energy’s (DOE) Waste Isolation Pilot Plant (WIPP) near Carlsbad, New Mexico, 

from May 10 through May 12, 2011, in accordance with 40 CFR 194.21. The WIPP is a disposal 

system for defense-related transuranic (TRU) waste as defined by the WIPP Land Withdrawal Act.1

 

EPA certified that WIPP complies with the Agency’s radioactive waste disposal regulations (Subparts B 

and C of 40 CFR Part 191) on May 18, 1998. 

The purpose of this annual inspection is to determine that waste sent to WIPP during the past year 

has been emplaced in the underground facility in the manner specified in DOE’s Compliance 

Certification Application and other approvals. The inspection reviews the site’s ability to receive, 

process, and emplace contact-handled and remote-handled TRU wastes within the repository, the 

emplacement of magnesium oxide (MgO) backfill in appropriate amounts to fulfill DOE commitments 

and requirements, and the maintenance of records pertaining to waste shipping, packaging, and 

emplacement, including the electronic Waste Data System (WDS). EPA examined selected activities, 

such as RH and CH waste processing, waste emplacement activities, and record keeping. 

 EPA concluded that DOE’s emplacement activities are adequate, that cellulosic, plastic and rubber 

material (CPR) is appropriately tracked and recorded, that MgO balances are calculated properly, and 

that MgO is emplaced properly. EPA observed the use of the proper waste emplacement procedures in 

the underground and successful implementation of the WDS bar code reader. EPA did not identify any 

findings or concerns during this inspection.

2.0 INSPECTION PURPOSE AND SCOPE 

 The purpose of this annual inspection is to verify that contact-handled (CH) and remote-handled 

(RH) transuranic (TRU) waste sent to WIPP during the past year has been emplaced in the underground 

facility in the manner specified in DOE’s Compliance Certification Application (EPA Air Docket A-93-

02, Item II-G-01) and other approvals. EPA performed this inspection under the authority of 40 CFR 

194.21, which authorizes the Agency to inspect WIPP during its operational period to verify continued 

compliance with EPA’s WIPP Compliance Criteria and the certification decision of May 18, 1998. 

Emplacement of waste and backfill, in particular, is relevant to compliance because the emplacement 

method supports the models that DOE uses in the WIPP performance assessment. 

 The primary focus of this year’s inspection was to evaluate the changes relative to the 

emplacement activities, particularly with regard to the handling and emplacement of the Standard Large 

Box (SLB II) and documentation since the annual inspection of 2010. 

 Activities within the scope of this inspection included: demonstration of the WIPP site’s ability 

to receive, process, and emplace remote-handled (RH) and contact-handled (CH) TRU wastes within the 

repository, the use of magnesium oxide (MgO) backfill in amounts to fulfill certification requirements 

and other approvals, maintenance of relevant waste packaging records, including the electronic Waste 

Data System (WDS) and the verification of appropriately implemented quality assurance practices. The 

review and examination of documents related to these activities is an important part of the inspection 

process. The WIPP site is operated by Washington TRU-Solutions (WTS) under contract to DOE, and 

the majority of waste related activities onsite are described by or controlled through WTS procedures. A 

list of WTS procedures examined during this inspection is provided in Attachment G.

3.0 INSPECTION TEAM, OBSERVERS, AND PARTICIPANTS 

 The inspection team consisted of three EPA staff. Thomas Kesterson and Julia Marple of the 

New Mexico Environment Department observed the inspection activities. A partial list of inspection 

participants is provided in Table A.

4.0 PERFORMANCE OF THE INSPECTION 

The inspection took place from May 10 to May 12, 2011, at DOE’s Carlsbad Field Office 

(CBFO) and at the Waste Isolation Pilot Plant (WIPP) facility, which is located approximately 26 miles 

south east of Carlsbad, New Mexico. The opening meeting with CBFO and WTS personnel was held on 

the morning of May 10, 2011. Several DOE and WTS staff presented information addressing program 

status, updates and changes since the last EPA emplacement inspection which took place from June 29 

to July 1, 2010. The primary focus of emplacement inspection was to determine the nature and extent of 

changes taken place in the areas of emplacement activities and documentation since last year’s 

inspection, particularly with regard to the handling and emplacement of the Standard Large Box (SLB 

II). In the opening meeting Ed McGary presented the status and results of MgO program at the WIPP. 

EPA inspectors accompanied CBFO and WTS personnel into the underground repository on the 

morning of May 11, in order to examine waste packages and MgO that had been emplaced in Panels 5 

and 6. Inspectors reviewed paper records documenting that waste emplacement and MgO tracking were 

conducted in accordance with procedures. Inspectors selected several containers and recorded their 

numbers (see Figure 3 for container locations); the records for these containers were examined both in

the repository, and later using the WDS computer database, to verify correct waste information is 

recorded by DOE. WTS personnel answered EPA questions about how waste is handled and emplaced. 

The inspectors also examined air monitoring locations, and observed the measurement of geotechnical 

parameters and mining in Panel 7. 

During the afternoon of May 11, EPA inspectors observed operations CH and RH bay areas of 

the waste handling building aboveground. Also on May 11, inspectors remotely accessed the WDS, and 

were able to generate Container and Canister Data Reports for the RH boreholes and CH waste 

containers observed in the underground that morning. On the morning of May 12, inspectors discussed 

record-keeping procedures with WDS data administrators at the Carlsbad Field Office, and WTS 

personnel generated additional reports and queries for the inspectors. EPA presented its preliminary 

observations at a close-out meeting on the afternoon of May 12. 

5.0 WASTE EMPLACEMENT/WDS 

Wastes received at the repository include contact-handled (CH) transuranic wastes from Argonne 

National Laboratory-East (ANL-E) in Illinois, Los Alamos National Laboratory (LANL) in New 

Mexico, Idaho National Laboratory (INL), Hanford Site in Washington, Rocky Flats Environmental 

Technology Site (RFETS) in Colorado, Savannah River Site (SRS) in South Carolina, the Nevada Test 

Site (NTS) in Nevada, and the Oak Ridge National Laboratory (ORNL) in Tennessee. These wastes are 

received and emplaced in several configurations: Standard Waste Boxes (SWBs), 55-gallon drums 

assembled in groups of seven called a Seven Pack, 100 gallon drums for supercompacted waste, and Ten 

Drum Overpacks (TDOP). RH wastes from INL, ORNL, and SRS have been emplaced in the WIPP, 

using the 72-B canister. 

The repository is subdivided into panels, each panel consisting of seven rooms. At the time of 

the inspection, CH waste was being emplaced in Panel 5, Room 1 and RH waste in the walls of Panel 6, 

Room 7. CH waste containers are stacked in columns (waste stacks) combining SWBs, drum packs, and 

TDOPs (see Figures 2 and 3). TDOPs are always placed on the floor of the room, occupying the bottom 

and middle position of a waste column. SWBs and drums may be emplaced in any order, with most 

wastes emplaced as received. The waste columns are in a series of staggered rows, with a row 

consisting of three columns that span the distance of a disposal room from left to right (Figure 2). RH 

waste is placed in the walls on eight foot centers (Figures 1, 4, and 5).

Figure 2 Illustrates the arrangement of disposed contact-handled waste in underground. 

Represented are stacks of seven-packs of drums and standard waste boxes. 

 In Panel 6, Room 7 inspectors observed boreholes drilled to emplace RH containers, and 

observed the Horizontal Emplacement/Retrieval Equipment set up to emplace a RH canister (Figure 4). 

While underground in Panel 5, Room 1, EPA inspectors selected recently emplaced CH waste 

packages for review. The inspector noted the shipment identification numbers as read by the 

underground escort directly off the emplaced containers (See Figure 3 for CH locations). The containers 

selected are identified in Table B below.

Since the last inspection, DOE informed EPA of plans to emplace CH waste in the repository 

using a new container, the Standard Large Box, or SLB-II. The SLB-II requires the use of a new 

shipping container, the TRUPACT-III. At the time of this inspection, no waste had been shipped to 

WIPP using the SLB-II. While in the Waste Handling building on May 11, EPA inspectors observed the 
10

construction and testing of specialized robotic equipment, including the Yard Transfer Vehicle, which 

will be used to move and unload the TRUPACT-III in preparation for emplacement of the SLB-II. An 

EPA inspector returned to observe a demonstration of this equipment and implementation of relevant 

procedures on June 14, 2011. EPA will continue its oversight to verify that the emplacement of waste 

using the SLB-II is conducted appropriately. 

On the morning of May 12 at CBFO, inspectors met with WTS personnel, who answered 

questions and generated the Nuclide Report, Waste Emplacement Report and the MgO safety factor 

calculations. All electronic records were found to contain required waste stream, container, and 

emplacement information. 

6.0 MAGNESIUM OXIDE BACKFILL

` 

 Magnesium oxide (MgO) is the engineered barrier used in the repository as backfill, as specified 

in DOE’s Compliance Certification Application (CCA). EPA requires DOE to maintain an MgO safety 

factor (excess factor) to ensure that adequate MgO is chemically available to control the chemistry of 

each room after closure. EPA approved lowering the required safety factor to 1.2 from 1.67 in a letter 

dated February 11, 2008, requiring the emplacement of sufficient MgO to react with 1.2 times the 

amount of carbon present in the repository. Conditions of EPA’s agreement stipulate that DOE must 

ensure a minimum reactivity of 96% for the MgO emplaced, and maintain the safety factor on a roomby-room basis. DOE instituted this change in March 2009, and it was a focus of EPA’s 2009 inspection. 

During the opening meeting, Edward McGary and Gene Valett gave a presentation updating 

DOE’s MgO Program and management. The following information was provided: 

 MgO bulk shipment deliveries from Manistee, Michigan continue on an as-needed basis. 

. 

 The local bagger vendor (Questa Fertilizer, Loving, NM) continues with super sack 

deliveries on an as needed basis (Generally delivered weekly). 

 The lab of record (ALS Laboratory Group, Fort Collins, Colorado) continues to conduct 

reactivity analysis sample testing on an as needed basis or whenever bulk shipment of 

MgO is requested. 

 All necessary documentation for the MgO program continues according to the RIDS 

documentation system. 

 No technical changes to the program since the last EPA Annual WIPP Inspection in 

2010. 

 Reactivity results since last visit: 

1. Average reactivity from June 29th - September 30th was 97.3% (June 29th EPA 

Annual WIPP Inspection for FY 2010). 

2. Average reactivity from October 25th - February 15th was 98.0 

3. The average reactivity for the above is 97.65. 

Process steps guiding MgO placement and documentation in the underground continue to be 

found in WP 05-WH1025, CH Waste Downloading and Emplacement, and WP-05-WH.02, WIPP Waste 

Handling Operations WDS User’s Manual. Waste Handling Engineers (WHE) may record the quantity 

and placement of MgO electronically using a WWIS/WDS bar code reader, or manually via paper forms 
11

if a bar code reader is unavailable. The appropriate forms (CH Waste Downloading and Emplacement 

Data Sheet and Supersack/BRT Emplacement Data Sheet) are included as Attachments 1 and 3 of WP 

05-WH1025. While in the underground repository, EPA inspectors verified that the proper procedures 

were used to track MgO emplacement in Panel 5, Room 1 and that MgO was emplaced on top of the CH 

waste stacks as stipulated. At the conclusion of each shift, the WHE must electronically verify the 

safety factor of 1.2 using the WDS. MgO safety factor calculations made using the WDS allowed 

inspectors to verify that a MgO safety factor in excess of 1.2 is being maintained in Panel 5, Room 1. 

Checklist items 12-17 and 24 specifically relate to MgO management and demonstrate that DOE 

has appropriate processes in place to ensure that MgO is properly emplaced. 

DOE is emplacing waste stacked 2-3 containers high topped with MgO Supersacks. Figure 3 

shows all container types being shipped to date. Large drums are Ten Drum Overpacks (TDOPs), black 

barrels are 100-gallon drums with supercompacted waste, smaller white containers are standard waste 

boxes, and standard 55-gallon drums appear in 7-packs. 3000 lb MgO supersacks are visible on top of 

the stacks.

7.0 COMPARISON WITH INVENTORY LIMITS 

In the Summary of Waste Emplacement Inventory Report, available through the EPA dashboard, 

EPA was provided data for emplaced waste, including total activities of the ten EPA-tracked 

radionuclides, total weights of ferrous and non-ferrous metals, and the CPR/MgO balance by room, as of 

April 7, 2011. More detailed data on the total amounts of specific materials emplaced was provided by 

WDS staff, using a script to run a custom WDS query. 

 EPA establishes limits for certain waste components at WIPP by approving performance 

assessment inventory estimates. Some limits, such as for iron and other metals, are minimum limits. 

The amount of iron and steel are now at 21,762,561kg. The minimum limit of 2 x 107

 kg iron has now 

been met for the repository. Other waste component limits are maximum limits. Of special concern is 

the maximum limit on the total amount of cellulosic, plastic and rubber (CPR) materials. In the original 

CCA, DOE calculated 2.2 x 107

 kg of CPR, establishing EPA’s limit. In the subsequent performance 

assessment baseline calculations, DOE added packaging materials to the calculations, and now the CPR 

limit for WIPP is 2.4 x 107

 kg (see Table C). CPR values are tracked on a per container basis and the 

current CPR values as of March 31, 2011are listed in Table C. 

 As of this inspection the WIPP contained almost 5,429,253.20 kg of CPR in waste and 

1,540,281.56 kg of CPR in packaging material. In addition, emplacement CPR, such as the slip sheets 

used to aid the emplacement of the containers, accounts for another 437,035.28 kg of CPR. This is a 

total of 7,406,570.04 kg of cellulosic, plastic and rubber material. The mass of rubber materials currently 

accounts for approximately 4.7% of the total mass of CPR, compared to 4.3% in 2010, 3.4% in 2009, 

5% in 2008, 4.7% in 2007, and 7% in 2006. The WIPP currently contains approximately 30% of its 

maximum limit for CPR. The repository held 29% of its limit for CPR in 2009, 24% in 2008, and 21% 

in 2007.

8.0 SUMMARY OF RESULTS

 The inspectors reviewed emplacement operations, WTS procedures, and records associated with 

selected containers. The surface processing of CH and RH waste as well as underground operations 

were reviewed and found to be adequate, according to specified plans documented in the CCA. EPA 

concludes that DOE’s emplacement activities and records are adequate, and that CPR and MgO are 

appropriately tracked. EPA identified no findings or concerns with the emplacement portion of the 

inspection.

 # Questions: Comments and Objective Evidence Results

Waste Emplacement

1 Is waste being emplaced in the 

underground facility in the 

manner specified in DOE’s 

Compliance Certification/ ReCertification or other relevant 

documentation?

Yes. Procedure WP 05-WH1025, CH Waste 

Downloading and Emplacement, Section 2, describes 

the CH emplacement procedures. Visual verification 

of the emplaced waste in Rows 146 through 148 of 

Panel 5, Room 4 confirmed waste emplacement in 

accordance with facility procedure and CCA 

documentation . 

RH processing procedures for 72-B (WP 05-WH1710, 

WP 05-WH1725) and 10-160-B (WP 05-WH1722) 

containers are consistent with the approach discussed 

in the CCA documentation. Emplacement in the 

repository walls with borehole plugs was verified 

during inspection of the underground. 

Satisfactory

2 Are CH waste containers stacked 

in columns appropriately given 

the type of container?

Yes. In WP 05-WH1025, CH Downloading and 

Emplacement, a note at step 2.25 specifies appropriate 

stacking of CH container types. Attachment 2 of the 

same procedure specifies payload assembly 

positioning. Visual verification confirmed adherence 

to procedure (e.g. TDOPs placed in bottom position of 

waste columns.)

Satisfactory
22

3 Are records adequate? 

Randomly select 3-4 CH and 2-3 

RH waste containers to verify 

records for waste approval, 

shipment, and receipt.

Yes. TRU Waste Receipt WP 08-NT3020, Rev.18 

describes the process. Records produced are Uniform 

Hazardous Waste Manifest, TRU Waste Receipt 

Checklist, Shipment Summary Report, RH waste 

Processing Data Sheet, Radiological Survey Report, 

and Waste Emplacement Report. CH waste produces 

comparable records. EPA reviewed records and found 

the records to be adequate and traceable.

4 Is DOE properly emplacing 

backfill material (magnesium 

oxide [MgO]) with the waste 

packages? 

Are supersacks placed on top of 

waste stacks according to 

procedure?

Yes. 3000-pound supersacks were observed to be 

emplaced on top of each waste assembly at the active 

waste face in Panel 5 Room 1. WP 05-WH1025, CH 

Waste Downloading and Emplacement, Section 3.0, 

establishes procedure for emplacement of MgO.

Satisfactory

5 Verify documentation for the 

containers listed in item 3 - waste 

generator site transmittal of waste 

to WIPP, WIPP approval, 

shipment certification for 

transport to WIPP, shipment 

initiation documentation, 

shipment received at WIPP 

records, waste emplaced in the 

underground, and placement of 

engineered barrier [MgO].

Inspectors examined paper records maintained 

underground and electronic records kept aboveground 

for the selected containers. Site operators 

demonstrated the use of the WDS bar code reader to 

track emplacement of waste and MgO. 

Documentation was determined to be adequate.

Satisfactory
23

RH Waste 

Emplacement Questions

 

6 Are RH containers approved for 

receipt, received, processed, and 

emplaced properly?

Yes. Inspection of the underground and RH handling 

area showed procedures to be in agreement with WP 

05-WH1710, 72-B RH Processing, and WP 05-

Question: Procedure 

12 Do DOE procedures reflect an 

MgO safety factor to 1.2?

Partially. WP 05-WH1025, CH Waste Downloading 

and Emplacement, Rev. 1, Section 3.0, Backfill, 

establishes procedures to maintain a safety factor of 

1.2 or greater per room on a daily basis. Procedures in 

the WDS User’s Manual, WP-05-WH.02, Rev. 0, 

Sections 6.2.5, 9.5.3, and Attachment 1 reflect the 1.2 

safety factor and the use of 3,000-lb. supersacks as 

necessary. WHEs were observed to be using current 

procedures and the WDS bar code reader to record 

MgO emplacement in the underground. 

Satisfactory

13 Are both CPR and MgO 

calculated and tracked on a roomby-room basis?

Yes. Calculations are performed by the Waste 

Handling Engineer at the conclusion of each shift, 

through the WDS, using the MgO Balance Report or 

Daily Report, as required by WP 05-WH1025, CH 

Waste Downloading and Emplacement, Rev. 1, 

Section 3.0, Backfill.

Satisfactory

14 Are sampling and analytical 

procedures in place to ascertain 

that emplaced MgO maintains a 

minimum of 96% reactivity?

Yes. Specification D-0101, Prepackaged MgO 

Backfill, Rev. 8 and WP 05-WH1105, MgO Sample 

Records Management, Rev. 0, set forth analytical and 

document management procedures to verifying that 

each shipment of MgO maintains a 96 +/- 2% 

reactivity.

Average reactivity from October 25th (2010) - 

February 15th (2011)was 98.0 

The average reactivity for the above is 97.65. 

Satisfactory

15 Is the acceptance of the MgO 

backfill material from the supplier 

documented?

Yes. WP 05-WH1105, MgO Sample Records 

Management, Rev. 0, Sec. 2.0 requires each shipment 

to be numbered, and the MgO supplier to provide an 

Analysis of Shipment and a sample under Chain of 

Custody for each shipment. Supersacks in the 

underground were observed by inspectors to be 

marked with unique ID numbers, traceable to their 

original shipments. 

Satisfactory

16 For the MgO needed for high 

CPR, are there procedures or 

documentation for the WHE or 

WHM (or other appropriate 

personnel) identifying when and 

where additional MgO is needed?

Yes. General procedures are found in the WIPP 

Waste Handling Operation WDS User’s Manual, WP 

05–WH.02, Attachment 1, Special Requirements for 

Additional MgO. Section 3 of WP 05-WH1025 calls 

for notification of the WHM if daily reports show the 

MgO safety factor of a room to be less than 1.2.

Satisfactory

17 Is there documentation that 

identifies how MgO should be 

placed with high CPR waste?

Yes. WP 05-WH1025, CH Waste Downloading and 

Emplacement, Attachment 3, Supersack/BRT 

Emplacement Data Sheet; and WP 05-WH1058, CH 

Waste Handling Abnormal Operations, Sec. 4.0, BRT

# Question: Records/WDS 

Do the characterization module, 

certification module, shipping 

module, and inventory module 

adequately record required 

information?

WWIS modules have been replaced by WDS 

Dashboards. Reports available through the EPA 

Dashboard contain the container number, shipment 

number, emplacement data and underground location. 

EPA staff queried the WDS to verify that this 

information is recorded correctly.

Satisfactory

19 Does the WDS adequately 

document waste shipment and 

emplacements information for 

waste containers selected? (Item 3 

above) CH, RH

Yes. Canister, Overpack, and Container Data Reports 

were retrieved, all of which correctly reflected 

container number, shipment number, and 

emplacement information in the underground.

Satisfactory

20 Do records verify that contact 

handled waste container surface 

doses fall within statutory 

requirements? Where are CH 

surface dose records maintained? 

Yes. CH surface dose measurements are recorded in 

the Container Data Report. Dose limits for each of the 

containers examined by EPA inspectors (listed in Item 

3) were below statutory limits. 

Satisfactory

21 Review a Waste Container Data 

Report. Does this report 

adequately record the Waste 

Stream Profile Form information?

Yes. For all containers inspected, inspectors found 

Container and Canister Data Reports to contain Waste 

Stream IDs, as well as all necessary radiological and 

chemical profile information.

Satisfactory

22 Review the Shipment Summary 

Report. Does the report correctly 

record the containers shipped? 

CH, RH 

By querying the Shipment number, the Shipment Data 

report may be generated. Inspectors verified that the 

report reflects the containers shipped. 

Satisfactory

23 Review the Waste Emplacement 

Report. Does this report 

adequately record the date of 

receipt, and disposal locations of 

containers? CH, RH 

Yes. See Item 21. Satisfactory

24 Is DOE assuring that the 1.2 

safety factor being maintained on 

a room basis?

Does the WDS accurately 

calculate the safety factor and 

recommend the proper amount of 

MgO to emplace?

Yes. See questions 12-17.

EPA inspectors reviewed InSEI Matrix Requirements 

WWIS2-REQ-2126 and -2127 to verify that the WDS 

software calculates MgO excess appropriately.
