Executive Summary
This report supports the U.S. Environmental Protection Agency (EPA)'s proposed baseline approval of the contact-handled (CH) transuranic (TRU) waste characterization program implemented by the Advanced Mixed Waste Treatment Project (AMWTP) at the U.S. Department of Energy's (DOE's) Idaho National Laboratory (INL), located near Idaho Falls, Idaho, consistent with the limitations described in this report. This baseline inspection:
 Evaluates AMWTP-implemented changes to the Acceptable Knowledge (AK) process, referred to as Enhanced AK, addressing the waste characterization process deficiencies noted by the DOE Accident Investigation Board; and
 Is subject to public comment on the EPA's proposed approval of the waste characterization components inspected as part of the baseline inspection.
 In October 2006, the EPA approved the AMWTP's contact-handled (CH) TRU waste characterization program. (EPA Docket No. A-98-49; II-A4-66, October 2006) Between 2006 and 2015, the EPA conducted continued compliance inspections to verify that the AMWTP continue to characterize CH TRU waste using the EPA-approved waste characterization program components. The EPA also approved Tier 1 changes that added new waste streams, equipment, processes and procedures or significantly revised the EPA-approved waste characterization activities. However, the changes to the DOE's WIPP Waste Acceptance Criteria due to the February 2014, radiation release necessitated that the AMWTP make changes to their waste characterization program particularly acceptable knowledge. The EPA determined that these changes to the Waste Acceptance Criteria and the Enhanced Acceptable Knowledge process implemented at TRU generator sites are significantly different from the processes the EPA evaluated during previous site-specific inspections. As a result, the EPA informed the DOE that a new AMWTP baseline inspection and approval would be a necessary step to evaluate the technical adequacy of the newly-implemented Enhanced Acceptable Knowledge process at the AMWTP. 
The EPA conducted a baseline inspection (EPA Inspection No. EPA-AMWTP-Fluor Inspection No. 08.17-8) of the waste characterization program for the CH TRU debris, solid, and soil waste at the AMWTP on August 8 - 10, 2017, in accordance with 40 CFR Part 194 of the Code of Federal Regulations [40 CFR 194.8(b)]. Upon the Agency's final approval, the DOE may resume emplacing AMWTP CH TRU waste in the Waste Isolation Pilot Plant (WIPP). Also upon the EPA's final approval of the AMWTP's newly-implemented changes, the DOE may resume disposal of AMWTP CH TRU waste streams characterized in the manner discussed in this report.
The scope of the baseline inspection included:
 The acceptable knowledge process, focusing on the Enhanced AK process for CH TRU waste.
 The nondestructive assay (NDA) process, specifically, four Canberra Integrated Waste Assay Systems (IWAS), the Retrieval Box Assay System (RBAS), the Waste Assay Gamma Spectrometer (WAGS) and the Stored Waste Examination Pilot Plant (SWEPP) Gamma-Ray Spectrometer (SGRS).
 Visual examination (VE) and real-time radiography (RTR) using three RTR units for characterizing the physical waste components of TRU waste containers belonging to all CH waste summary categories (S5000, heterogeneous debris; S4000, soils; and S3000, homogeneous solids).
Attachment K is a list of all documentation reviewed, including all documentation revised during the inspection process and the batch data reports.
This baseline inspection evaluated the AMWTP's CH TRU waste characterization program for technical adequacy. When approved, the AMWTP will be allowed to continue using the program components to characterize contact-handled waste in accordance with the conditions and restrictions discussed in this report. The EPA is proposing to approve the AMWTP waste characterization program implemented to characterize contact-handled transuranic waste as documented in this report. Specifically, the proposed approval includes:
       The AK process for transuranic waste at the AMWTP, including the Enhanced AK process
       The four NDA systems (IWAS, RBAS, WAGS and SGRS) for characterizing CH TRU waste
       The VE and RTR processes to identify waste material parameters and the physical form of CH TRU waste.
Any changes to the waste characterization activities after the date of the baseline inspection must be reported to and, if applicable, approved by the EPA according to Table 1. All Tier 1 changes must be submitted for approval before their implementation and will be evaluated by the EPA. Upon approval, the EPA will post the results of the evaluations through the EPA website and the WIPPNEWS list. The AMWTP must submit Tier 2 changes that have been implemented four times a year, at the end of each fiscal quarter.
The EPA's final approval decision about the AMWTP's CH TRU waste characterization program will be conveyed to the DOE separately by letter following the Agency's review of public comments received responding to the proposed approval discussed in this report. This information will be provided through the EPA website and by emails to the WIPPNEWS list, in accordance with 40 CFR 194.8(b)(3).

Purpose of Baseline Inspections
On May 18, 1998, the EPA certified that the WIPP would comply with the radioactive waste disposal regulations in 40 CFR Part 191. In that certification, the EPA also included Condition 3, which states that "the Secretary shall not allow shipment of any waste from...any waste generator site other than [LANL] for disposal at the WIPP until the Agency has approved the processes for characterizing those waste streams for shipment using the process set forth in §194.8." The approval process described in 40 CFR 194.8 requires the DOE to (1) provide the EPA with information on AK for waste streams proposed for disposal at the WIPP, and (2) implement a system of controls used to confirm that the total amount of each waste component that will be emplaced in the WIPP will not exceed limits identified in the most recent WIPP Compliance Certification Application. 
The rule applying to this baseline inspection can be found in the Federal Register (Vol. 69, No. 136, pp. 42571 - 42583, July 16, 2004). According to these regulatory changes, the EPA must perform a baseline inspection of a TRU waste generator site's waste characterization program to determine technical adequacy of the processes, procedures and equipment implemented for characterizing WIPP-bound waste. This review is based on the demonstration that the program's components, with applicable conditions and limitations, can adequately characterize TRU wastes and comply with the regulatory requirements imposed on TRU wastes destined for disposal at the WIPP. An EPA Inspection Team conducts an onsite inspection to verify that the site's system of controls is technically adequate and properly implemented. Specifically, the EPA's Inspection Team verifies compliance with 40 CFR 194.24(c)(4), which states the following:
      Any compliance application shall: . . . Provide information which demonstrates that a system of controls has been and will continue to be implemented to confirm that the total amount of each waste component that will be emplaced in the disposal system will not exceed the upper limiting value or fall below the lower limiting value described in the introductory text of paragraph of this section. The system of controls shall include, but shall not be limited to: measurement; sampling; chain of custody records; record keeping systems; waste loading schemes used; and other documentation. 
In other words, the purpose of the baseline inspection is to evaluate the implementation of 40 CFR Part 194 requirements by assessing whether the DOE sites that characterize TRU waste prior to disposal at the WIPP are capable of adequately doing so. The EPA may also conduct follow-up inspections to address issues remaining from the baseline inspection or to seek further clarification/discussion related to waste characterization processes evaluated during a baseline inspection. By approving the waste characterization systems and processes at the AMWTP for CH TRU waste, the EPA confirms that it has evaluated the capabilities of systems and processes implemented by the site to accomplish two tasks: (1) identification and measurement of waste components, such as plutonium (Pu), that must be tracked for compliance and (2) confirmation that the waste in any given container has been properly identified as belonging to the group of approved waste streams. 
Purpose of This Report
This report documents the basis for the EPA's proposed approval of the AMWTP waste characterization program for CH TRU wastes. Specifically, this report:
 Describes the AMWTP waste characterization systems proposed for approval.
 Delineates a specific set of CH wastes proposed for approval.
 Provides objective evidence supporting the proposed approval basis for all waste characterization systems.
 Identifies all relevant system limitations and/or conditions for each waste characterization system and/or waste containers that are subject to this proposed approval.
Scope of Inspection
The scope of Baseline Inspection No. EPA-AMWTP-Fluor Inspection No. 08.17-8 included the technical adequacy of the waste characterization systems used by the AMWTP to characterize solid (S3000), soil (S4000) and debris (S5000) CH TRU waste. The EPA conducted this baseline inspection of the AMWTP on August 8 - 10, 2017, at INL near Idaho Falls, Idaho.
The purpose of this inspection was to determine the site's compliance with 40 CFR 194.24. The EPA Inspection Team evaluated the AMWTP waste characterization systems with respect to AK, seven NDA systems, and VE and RTR as nondestructive examination systems.
The EPA performed this inspection by executing the following:
 Obtained and reviewed site procedures, reports and other technical information used to characterize CH TRU waste.
 Observed NDA, VE and RTR processes implemented at the AMWTP.
 Prepared technical questions prior to the inspection based on the activities listed in (1) above.
 Interacted with Carlsbad Field Office (CBFO) and the AMWTP personnel to arrange inspection logistics.
 Evaluated the AMWTP's implementation of waste characterization processes for adequacy and demonstrating compliance with 40 CFR 194.24 requirements.
 Conducted the baseline inspection to verify the technical adequacy and/or qualifications of CH waste characterization personnel, procedures, processes and equipment, as documented in the AMWTP's records.
 Evaluated the correlations of containers to identify common attributes.
 Communicated all pertinent information to CBFO and AMWTP personnel.
 Conducted entrance, exit and daily briefings for CBFO and AMWTP management personnel for all segments of the inspection.
 Obtained and reviewed AMWTP documents that were revised and/or created in response to inspection.
 Issued the draft inspection report and proposed approval.
During an inspection, the EPA does not approve characterization data; that function is the sole responsibility of the entity being evaluated  -  the AMWTP in this case. The EPA evaluates the site's waste characterization processes to characterize CH TRU waste. The AMWTP evaluation consisted of reviewing training records and interviewing waste characterization personnel to assess their understanding of (1) the EPA's TRU waste characterization and WIPP waste disposal requirements, (2) waste characterization processes implemented and available as alternatives and (3) the AMWTP's documentation and record-keeping procedures. 
In addition, the EPA evaluation focused on observing equipment operations and waste characterization practices at the AMWTP controlled by site procedures, and inspecting records related to each of the waste characterization processes within the inspection's scope. An important aspect of this evaluation is the objective evidence documenting the effectiveness of the waste characterization processes. Objective evidence typically takes the form of AK, NDA, VE and RTR records, including batch data reports. During this inspection, the EPA selected samples of each of these items, based on the number and variety of items each waste characterization process produced, consistent with standard auditing techniques. Based on an evaluation of the waste characterization processes in conjunction with the objective evidence, the EPA determined the technical adequacy of these processes and associated records within the inspection's scope.

Technical Evaluation
Sections 6.2 through 6.5 of this report detail the four technical areas assessed during this inspection: AK, NDA, RTR and VE. Completed inspection checklists are included in Attachments C, D, E, F, G, H, I and J.
Advanced Mixed Waste Treatment Project Background 
The AMWTP is located in the Idaho National Laboratory (INL) site, approximately 80 miles west of Idaho Falls, Idaho. The primary mission of the AMWTP since December 2008 has been characterization and treatment of TRU waste from across the DOE complex. 
Previous EPA Inspections/Approvals
The EPA initially approved the AMWTP's CH TRU waste characterization program in October 2006 (A-98-49; II-A4-66; October 3, 2006). Between 2006 and 2015, as shown in Attachemnt A, the EPA conducted continued compliance inspections to verify that the AMWTP continued to characterize CH TRU waste using the EPA-approved waste characterization program components. The EPA also approved Tier 1 changes that added new waste streams, equipment, processes and procedures or significantly revised the EPA-approved waste characterization activities. However, the changes to the DOE's WIPP Waste Acceptance Criteria due to the February 2014, radiation release necessitated that the AMWTP make changes to their waste characterization program particularly acceptable knowledge. The EPA determined that these changes to the Waste Acceptance Criteria and the Enhanced Acceptable Knowledge process implemented at TRU generator sites are significantly different from the processes the EPA evaluated during previous site-specific inspections. As a result, the EPA informed the DOE that a new AMWTP baseline inspection and approval would be a necessary step to evaluate the technical adequacy of the new Enhanced Acceptable Knowledge process at the AMWTP. 
After June 2015, when the WIPP Waste Acceptance Criteria, Rev. 8.0, became effective, the AMWTP revised the EPA-approved AK process to incorporate the revised AK requirements. As stated previously, the Agency determined that these AK changes to be significantly different than what the EPA had approved as part of the October 2006 baseline approval, thus requiring a new baseline inspection and approval. The EPA's decision to conduct a baseline inspection of the AMWTP does not imply a change to the regulatory framework in 40 CFR Part 194. 
Acceptable Knowledge (AK)
Waste Characterization Element Description
The EPA evaluated the AMWTP's AK waste characterization program for CH TRU waste characterization, focusing on the new Enhanced AK process. The EPA conducted this inspection by reviewing documents and records associated with a representative sample of S3000 (homogeneous solids) and S5000 (heterogeneous debris) waste. Inspection details and specific documents and records evaluated for each Item summarized below are recorded in the AK checklist that is included in Attachment C. The EPA did not evaluate any AK documentation related to S4000 (soil) waste streams; however, the EPA determined that the AK process for characterization of S4000 would be the same as the process evaluated during this inspection. Completion of documentation associated with the creation and characterization of an S4000 waste stream by the AMWTP is a Tier 2 reporting requirement, as described below (see Table 1).
Technical Evaluation
The EPA examined personnel training and qualifications and found them to be adequate.
The AMWTP provided qualification cards for all Acceptable Knowledge Experts and Site Project Managers that actively work with the AMWTP waste characterization program. The EPA reviewed example qualification cards and screenshots of the qualifications/certifications database showing the qualification dates and expiration dates for all AMWTP AK Experts and Site Project Managers. The EPA also interviewed a portion of the listed AK Experts and Site Project Managers and one Waste Certification Official. The EPA has no issues with AMWTP personnel qualifications for AK Experts, Waste Certification Officials, or Site Project Managers.
Submission to the EPA of a list of AK Experts and Site Project Managers who performed work in these roles for the AMWTP waste characterization program in the previous quarter is a Tier 2 reporting requirement (see Table 1).
The EPA assessed nonconformance and discrepancy resolution documentation and found it to be adequate. 
The EPA evaluated sample AK resolution checklists, discrepancy resolution reports and nonconformance reporting and found that the discrepancies were adequately documented and resolved. The EPA also observed use of the AK Resolution Ledger to track AK resolution checklists and associated action items. The AMWTP AK process includes reviewing the AK Resolution Ledger for open action items periodically and any time an AK summary report or generator-site-specific AK document is being revised. 
The EPA assessed documentation of waste stream definitions and waste traceability and found that the definitions are adequately supported and waste containers are adequately traceable.
The EPA evaluated waste stream definitions documented in two AK summary reports and supported by various source documents, AK documents and topic-specific reference documents (i.e., RPT-TRUW-05, RPT-TRUW-07 and RPT-TRUW-12). During this evaluation, the EPA verified:
 All waste within a waste stream was generated from a single process or activity.
 All waste within a waste stream is similar in material and physical form, and the expected physical parameters are adequately described.
 The expected radiological parameters are adequately documented.
 Any use of AK (and associated limitations) in NDA is clearly documented and communicated between AK and NDA personnel.
 Waste containers assigned to specific waste streams are traceable from generation through characterization and have documentation supporting inclusion in the waste stream.
Notification to the EPA upon completion of or substantive modification to all AK summary reports, AK documents and the three topic-specific reference reports RPT-TRUW-05, RPT-TRUW-07 and RPT-TRUW-12 are T2 changes (see Table 1).
The EPA evaluated implementation of the Enhanced Acceptable Knowledge process and found it to be adequate.
The Enhanced AK process is intended to document (1) evaluation of container-specific AK to provide reasonable assurance that the waste container management and packaging activities are bounded by the applicable AK and (2) evaluation of waste-stream-specific AK to provide reasonable assurance that all potential chemical incompatibilities have been identified and evaluated for impact to long-term isolation of TRU waste.
The AMWTP currently has two ways of documenting the container-specific evaluation: (1) the Interface Waste Management Documents List (IWMDL; FRM-2274) form documenting the waste-stream-generating process for containers generated using current/present-day procedures or (2) an AK assessment memorandum for existing waste streams with unshipped containers. The AMWTP does not consider an IWMDL form complete and available for demonstrating container-specific evaluations until all the procedures listed in an IWMDL form have been evaluated. The AMWTP is still in the process of conducting walk-down evaluations of each of the procedures listed on their first IWMDL form. The EPA reviewed the signed IWMDL form and an example completed checklist for one of the procedures and interviewed the AK Expert responsible for conducting the walk-downs. The process is reasonable, and the EPA will continue to review the process during future evaluations. 
The AMWTP will document using AK assessment memoranda that the AK associated with each container has been reviewed and all waste handling procedures and waste management documents have been accurately and completely accounted for. When completing the AK assessment memorandum for the Waste Stream BNINW216 containers at the WIPP Waste Handling Building, AMWTP AK experts evaluated the Rocky Flats (where the waste was originally generated prior to 1980 and buried at the Idaho National Laboratory) procedures and controlled documents that were already in the AMWTP record but did not attempt to fill in any holes between revisions. This approach is reasonable for waste streams from facilities such as Rocky Flats where operations varied little over the years, but it may not be appropriate for other waste streams. The EPA will continue to review the process during future evaluations.
The waste-stream-specific evaluation for chemical compatibilities is currently being documented on a chemical compatibility evaluation (CCE) memorandum. In general, the AMWTP intends to generate one chemical compatability evaluation memorandum for each waste stream that has containers yet to be emplaced at the WIPP. The primary source of information for the chemical compatability evaluation memorandum is the AK summary report, but the AK expert also reviews relevant source documents to identify additional chemicals not deemed necessary for inclusion in the AK summary report. An additional chemist and transportation personnel are involved in decisions about quantity and reaction potential. The EPA reviewed the only draft (yet to-be-CBFO-approved) AMWTP chemical compatability evaluation memorandum available during the inspection and found that the assumptions that form the bases of the chemical compatability evaluation memorandum's conclusions are clearly documented to support the DOE's chemical compatibility determination. In this case, submission of the final chemical compatability evaluation memorandum is a Tier 2 reporting requirement. 
As part of the corrective actions resulting from the February 2014 event at the WIPP, CBFO "established criteria [in the Basis of Knowledge (BoK)] that must be used by the WIPP Certified Programs to evaluate TRU waste containing one or more oxidizing chemicals to determine acceptability at the WIPP as-is and to identify when additional evaluation or treatment is required." As in the AK assessment process, the AMWTP documents this evaluation for each container destined for emplacement at the WIPP. The primary sources of information for the evaluation are the AK assessment and chemical compatability evaluation memoranda. The AK assessment for the Waste Stream BNINW216 containers at the WIPP Waste Handling Building identified the quantities of liquid absorbed in each container. For the Basis of Knowledge analysis, the AK expert completed bounding calculations to show that appropriate quantities of absorbent were used during packaging. The technical assumptions used to evaluate the subject containers against the specified criteria of the Basis of Knowledge for the treatment and management of oxidizing materials are clearly documented in the example Basis of Knowledge memorandum the EPA reviewed.
The sample IWMDL form and AK assessment, chemical compatability evaluation and Basis of Knowledge memoranda that the EPA reviewed adequately demonstrate implementation of the Enhanced AK process. However, as a result of the AK assessment, chemical compatability evaluation and Basis of Knowledge memoranda are being considered as "memoranda" instead of "reports". As a result, currently, the AMWTP does not have a strong system in place to control the review and revision processes for these documents. The AMWTP was aware of this weakness and indicated that they are "working on it." Submission of theses documents upon completion is a Tier 2 change reporting requirement. The EPA will continue to evaluate the Enhanced AK process during future evaluations. 
Notification to the EPA upon completion of or substantive modification to Enhanced AK documentation, including IWMDL forms and AK assessment, chemical compatability evaluation and Basis of Knowledge memoranda, are Tier 2 changes (see Table 1). Note that this Tier 2 requirement applies to all substantive modifications and reissuances of these documents, not just those modifications that are considered "revisions."
The EPA evaluated the waste stream certification process and found it to be adequate.
The EPA evaluated samples of the documents commonly associated with Site Project Manager certification of the waste streams, including Reconciliation with Data Quality Objectives forms, characterization information summaries, waste stream profile form packages and AK accuracy reports. The EPA found that the AMWTP's certification process is adequate and appropriately documented.
Notification to the EPA upon completion of or substantive modification to all waste stream profile forms and any associated change notices is a Tier 2 reporting requirement (see Table 1).
Notification to the EPA upon completion of or substantive modification to AK accuracy reports (annually, at a minimum) is also a Tier 2 reporting requirement (see Table 1).
The EPA evaluated the AMWTP's overall system of controls and found them to be adequate.
The EPA evaluated the AMWTP's completeness of the sampled AK summary reports and AK documents and general compliance with the AK procedure as evidenced by successful completion of the required forms and found the documents to be complete. The applicable waste stream documentation includes estimates of the total waste volume and the percentage of the waste volume that is above and below 100 nanocuries per gram (nCi/g).
The WIPP Land Withdrawal Act (Public Law 102-579) as amended by Public Law 104-201 states that waste identified for emplacement at the WIPP must be defense in origin, must not be spent nuclear fuel and must not be high-level waste. The EPA received sample AK summary reports and AK documents. In these documents, the DOE states that the waste has a defense origin and does not contain spent nuclear fuel or high-level waste. (For more details, see references C191A, TRUW-09 and TRUW-83 for AKSRs, as well as TRUW-56, TRUW-06 and TRUW-XX.)
The overall system of controls also includes the NDA, RTR and VE controls described in sections 6.3 through 6.5 of this report. The EPA finds that the system of controls in place at the time of this baseline inspection are adequate for ensuring the long-term isolation of TRU waste.
Any change to the payload management status of approved waste streams by the AMWTP is a Tier 2 reporting requirement (see Table 1). Changes to AMWTP procedures impacting the processes described in this report and requiring CBFO approval are also to be reported as Tier 2 changes (see Table 1).
Acceptable Knowledge Conclusion
Changes to Tiering
The EPA did not identify any Tier 1 changes relative to the AK process at the AMWTP. The EPA identified several Tier 2 changes, as described throughout section 6.2 and summarized in Table 1. The Tier 2 reporting requirements for AK are:
 Submission of a list of active AMWTP CH AK Experts and Site Project Managers who performed work during the previous quarter
 Notification to the EPA upon completion of or substantive modification to:
 RPT-TRUW-05, RPT-TRUW-07 and RPT-TRUW-12 
 AK accuracy reports (annually, at a minimum)
 Waste stream profile forms and any associated change notices
 AK summary reports and generator-site-specific AK documents
 Site procedures requiring CBFO approval
 The payload management status of approved waste streams
 Enhanced AK documents such as Interface Waste Management Documents List forms and AK assessment, chemical compatability evaluation and Basis of Knowledge memoranda
The language in Table 1 regarding AK documentation applies to all AMWTP CH waste streams, unless specifically stated otherwise.
The Enhanced AK process, as implemented, provides extensive documentation of generator-site and AMWTP waste treatment and packaging practices and can support the AMWTP's assessment that the WIPP-bound AMWTP TRU waste containers as processed do not exhibit characteristics of ignitability and reactivity, the main causes of the February 2014 WIPP radiation release.
Summary of Acceptable Knowledge Findings and Concerns
The EPA did not identify any AK-related findings or concerns. No open issues related to AK result from this inspection.
Proposed Acceptable Knowledge Baseline Approval
The EPA is proposing to approve the AK process, as observed during this inspection and in the context of the limitations described in this report. See Table 1 for AMWTP CH AK Tier 1 and Tier 2 changes resulting from this baseline inspection. 
Nondestructive Assay (NDA)
Waste Characterization Element Description 
The EPA evaluates several characteristics of an NDA measurement system during a technical inspection, including the range of conditions for which the instrument is capable of producing technically defensible data with regard to two aspects:
 Activity -- The nuclear disintegration rate of specific radiation types (neutron or gamma), typically special nuclear material or TRU radionuclides. Units of activity and mass are interchangeable by applying a conversion based on a radionuclide's specific activity.
 Physical characteristics -- The physical attributes of waste matrices as they relate to a radiometric system, i.e., how the matrix's physical properties interact with the radiations that originate within the sample and affect the system's ability to detect them. Examples include attenuation of photons and moderation and absorption of neutrons.
The AMWTP performs NDA on CH TRU wastes using the following seven NDA systems: 
 IWAS units Z-211-102 and Z-211-103, located in Building WMF-634
 IWAS units Z-390-100 and Z-390-101, located in Building WMF-676 
 WAGS, located in the SWEPP
 SGRS, located in the SWEPP 
 RBAS, located in Building WMF-634
The AMWTP uses these systems to identify and quantify the activities of the 10 WIPP-tracked radionuclides americium-241 ([241]Am), cesium-137 ([137]Cs), [238]Pu, [239]Pu, [240]Pu, [242]Pu, strontium-90 ([90]Sr), uranium-233 ([233]U), [234]U and [238]U and their uncertainties. Measurement data support a determination regarding the TRU alpha activity concentration of CH TRU waste containers. During this baseline inspection, the EPA inspected these seven AMWTP NDA systems, all of which had been evaluated and approved for characterizing TRU wastes at the AMWTP previously. The sections that follow describe all systems in detail.
The design and performance specifications of the four IWAS units are identical, although there are operational distinctions between the Z-211 and the Z-390 systems. As discussed in section 6.1, the SGRS and WAGS units were previously operated by INL-CCP and were transitioned to the AMWTP in 2015 (EPA Air e-Docket No. EPA-HQ-OAR-2001-0012-0466; April 4, 2016). The RBAS is a relatively new unit for CH TRU assays at the AMWTP, and EPA initially approved it in 2015 (EPA Air e-Docket No. EPA-HQ-OAR-2001-0012-0459; October 19, 2015). Specifically, the EPA reviewed the following elements of the NDA process for all seven AMWTP NDA systems:
 Capability of the measurement hardware and software to perform the required analyses for the radionuclides of interest, including their uncertainties, in the waste matrices of interest
 Technical adequacy of the NDA documents, procedures and controls
 Knowledge, understanding and training of NDA personnel at the AMWTP
Batch Data Reports Reviewed
During this inspection, the EPA evaluated batch data reports for all seven NDA systems. The specific batch data reports are listed below by assay system, including their AMWTP identifier and the types of containers that were assayed. As with all AMWTP records, the NDA batch data reports exist in electronic format only.

Technical Evaluation
Integrated Waste Assay System Units Z-211-102, Z-211-103, Z-390-100 and Z-390-101
The Z-211-102 and Z-211-103 IWAS units are located in Building WMF-634. The Z-390-100 and Z-390-101 IWAS units are located in the processing facility, Building WMF-676; they are also referred to as the in-plant systems by virtue of their location within the waste processing facility at the AMWTP. The following sections describe all four units; any differences are noted. 
 The EPA verified that the designs and essential functions of the four Integrated Waste Assay System units were technically adequate and essentially the same.
The Z-211 and Z-390 IWAS units are identically designed NDA systems that combine active neutron and passive neutron assays with gamma spectrometry in a single system. All four IWAS units quantify TRU radionuclides in 55-gallon drums; however, the Z-211 systems also assay 55-gallon overpacks (83- or 85-gallon). All four systems can assay a variety of waste matrices, including combustibles, glass, organic and inorganic sludge, and metals. However, the Z-390 systems are limited to assaying only debris wastes, while the Z-211 systems assay debris and solids. During the period from June 1, 2016, through August 9, 2017, the Z-390-100 unit assayed 7,121 drums, the Z-390-101 unit assayed 5,205 drums, the Z-211-102 unit assayed 4,463 drums and the Z-211-103 unit assayed 4,216 drums. Not all these assays are germane to this inspection, because assay results of containers that show less than 100 nCi/g of TRU radionuclides indicate that the containers are not WIPP eligible (i.e., are not TRU waste).
IWAS passive neutron assays use more than 100 helium-3 ([3]He) proportional counters, arranged in a 4Π geometry to detect the neutrons emitted from spontaneous fission, typically associated with [240]Pu or other even-numbered Pu isotopes. The IWAS estimates the quantity of [240]Pu (referred to as the [240]Pu effective or [240]PuEFF) based on the measured neutron flux. Other radionuclides are quantified by combining the observed [240]Pu value with isotopic ratios that are measured using two broad-energy germanium (BEGe) detectors, described below, or are based on approved AK isotopics. The system uses an Add-A-Source technique to correct for the effects of the waste matrix on the container's neutron emission by introducing a californium-252 ([252]Cf) source into the measurement chamber. The system's response to the [252]Cf source with the waste present is compared to the response without waste to provide a container-specific matrix correction.
In the active neutron mode, a pulsed source of 14 mega-electron volt neutrons is thermalized by the high-density polyethylene walls of the measurement chamber, and potentially the waste matrix itself, and induces fission in fissionable radionuclides, most notably [239]Pu. The IWAS detects the fission-induced neutrons in one of four Fast Neutron Detector Packs located in the walls of each of the drum measurement chamber. Each Fast Neutron Detector Pack consists of several [3]He proportional counters surrounded by high density polyethylene walls and wrapped in a thin layer of cadmium. Using a differential die-away analysis, the [239]Pu content is quantified, referred to as the [239]Pu effective or [239]PuEFF. Other radionuclides are quantified by combining the observed [239]PuEFF with isotopic ratios from the broad-energy germanium detectors or AK, in the same manner as with the [240]PuEFF for passive neutron assays.
In the gamma-ray assay mode, the two broad-energy germanium detectors located in the chamber walls determine radionuclide ratios and the absolute quantity of gamma-emitting radionuclides. The broad-energy germanium detectors are withdrawn from the chamber to prevent neutron damage from active neutron assays and they are reinserted post-active neutron assay. Gamma spectra from the broad-energy germanium detectors are analyzed with Canberra's NDA-2000 software and Multi-Group Analysis, which estimates the radionuclide ratios based on the relative heights of specific gamma energy peaks. When Multi-Group Analysis fails to provide a valid result, NDA-2000 uses default isotopics based on previous assays of either weapons-grade Pu, if [239]Pu is the dominant Pu isotope, or an isotopic mix consistent with heat-source Pu, if [238]Pu is the dominant Pu isotope. In some cases, TRU radionuclides are not detected but there may be significant quantities of depleted uranium. The Multi-Group Analysis-Uranium software package analyzes spectra from predominantly uranium-bearing wastes. Of course, drums containing only U with no measurable TRU signal are not eligible for shipment to the WIPP. The decision to use measured or default isotopic ratios is an automated function of the NDA software. There are no operator inputs or selections, and the NDA system does not use information directly from AK or the Waste Tracking System in making this determination.
The EPA had no concerns regarding the designs and essential functions of the four Integrated Waste Assay System units.
New equipment or substantive physical modifications to approved equipment is a T1 change (see Table 1). Notification to the EPA upon substantive modification to software for approved NDA equipment is a T2 change (see Table 1).
The EPA verified that the calibration of the Integrated Waste Assay Systems was adequate and noted that there were no major system changes apart from routine maintenance.
Canberra Industries calibrated all four IWAS units at its factory in Meriden, Connecticut, before shipment to the AMWTP. The calibration of each system was verified and documented in site acceptance reports CI-IDA-NDA-0051 through CI-IDA-NDA-0054.
The BEGe detectors are calibrated for gamma energies between 59 and 1,408 kiloelectron volts (keV). The active neutron calibrations are valid for absorber-moderator indices between 1.0 and 2.7, and the passive neutron for moderator indices between 1.0 and 3.0. This calibration is appropriate for a variety of waste matrices, including glass, combustibles, metal and sludge. The applicable waste sludge waste codes are 001, 002, 003 and 004; debris waste codes are 320, 330, 336, 339, 371, 374, 393, 432, 440, 441, 442, 480 and 481. The system has a stated upper limit of 12 grams (g) for [240]Pu mass, which correlates to approximately 200 g weapons grade Pu. The administrative control limit on the overall matrix correction factor is less than 6.0. The gamma calibration is applicable for low atomic number (low Z) materials (Z < 15) with densities up to 1.6 grams per cubic centimeter (g/cm[3]) and uses a matrix correction factor (which accounts for waste matrix effects) generated by a multi-energy matrix correction factor curve. To determine a drum's appropriate gamma measurement range, the system generates a bulk density, assuming that the drum is 100% full. 
The AMWTP presents the gamma operating range of the instruments as 0.010 to 200 g of weapons-grade Pu, although it is not a mass calibration in the strict sense. In theory, there is no mass limit, provided that the photon energy is between 59 and 1,480 keV and all operational and spectral parameters are acceptable. The software automatically selects the operational mode (i.e., gamma, active neutron or passive neutron) that is reported for each assay event based on the results that have the smallest total measurement uncertainty (TMU). Conceptually, the active neutron mode is selected for a weapons grade Pu content between 0.010 and 0.250 g, while the passive neutron mode is appropriate for measurements between 0.100 and 200 g weapons-grade Pu. Initially, the system was configured to automatically perform the active neutron assay first, but operational experience has shown that this mode was rarely used as the assay of record and its automatic use has been deactivated. It can still be used, but the operator must initiate it deliberately, which would typically happen if the passive neutron and gamma data indicated it was needed. The gamma-ray mode is most likely to be chosen to assay waste matrices with low-Z materials or low Pu content.
The EPA had no concerns regarding the technical adequacy of the IWAS NDA systems.
Extension of or changes to approved calibration ranges for approved equipment is a Tier 1 change (see Table 1). Notification to the EPA upon changes to the approved operating ranges of approved NDA systems upon CBFO approval is a Tier 2 change (see Table 1).
Notification to the EPA upon changes to IWAS procedures that require CBFO approval is a Tier 2 change (see Table 1).
The EPA verified that determination and documentation for the total measurement uncertainty (TMU) for the Integrated Waste Assay Systems are adequate.
The determination of TMU for all four IWAS units is documented in one document, CI-IDA-NDA-0055, "Total Measurement Uncertainty for the AMWTP Integrated Waste Assay Systems," Revision 1, July 30, 2003. The EPA evaluated this document and found that it addresses all major components of TMU. Uncertainty sources for the passive neutron mode included calibration, counting statistics, matrix/source distribution effects and elevated backgrounds due to high Z matrices. The active neutron mode TMU determination also includes contributions of calibration, counting statistics, matrix/source distribution effects, neutron multiplication and self-shielding. The gamma based TMU determination includes contributions from calibration, counting statistics, self-absorption, matrix and source heterogeneity and measurement of isotopic ratios.
The EPA had no concerns regarding the technical adequacy of the TMU determination and its documentation for the four IWAS units.
The EPA confirmed that the AMWTP's determination and documentation of the lower limit of detection, including the minimum detectable concentration, of the Integrated Waste Assay Systems was technically adequate.
The lower limit of detection (LLD) is defined as that level of radioactivity that, if present, yields a measured value greater than the critical level with a 95% probability, where the critical level is defined as that value measurements of the background will exceed with 5% probability. The LLD is a strong function of both the ambient background and the system's detection efficiency. NDA-2000 calculates the LLD and the minimum detectable concentration for each assay event based on the background and efficiency associated with that particular measurement.
The AMWTP determined nominal LLDs and minimum detectable concentrations for a variety of matrices for the active neutron, passive neutron and gamma modes by assaying surrogate drums of those matrices without radioactive sources. Matrices used for active neutron and passive neutron assays included combustibles, metals, glass and inorganic and organic sludge. For the gamma mode, the AMWTP estimated the LLD and minimum detectable concentration values for four matrices that varied in density from 0.0284 to 1.58 g/cm[3]. The nominal values were reported in CI-IDA-NDA-0053 through CI-IDA-NDA-0054, which the EPA Inspection Team reviewed and deemed to be adequate.
The EPA had no concerns regarding the determination and documentation of the LLD for the IWAS NDA systems.
The EPA assessed training of all Integrated Waste Assay Systems personnel and found it to be adequate.
All AMWTP personnel associated with the calibration, operation, data review and approval of the four IWAS units had current training, as evidenced by the screenshot of the qualifications/certifications database dated July 24, 2017, that the AMWTP provided before the inspection. The EPA has no concerns regarding the training of AMWTP IWAS NDA personnel.
Submission to the EPA of a list of all NDA personnel who performed work during the previous quarter remains an NDA Tier 2 change (see Table 1). Specifically, the list must include all IWAS operators, Expert Analysts and Independent Technical Reviewers.
The EPA established that the Integrated Waste Assay Systems successfully participated in the Carlsbad Field Office-sponsored Performance Demonstration Program.
All four IWAS units successfully participated in the CBFO-sponsored Performance Demonstration Program (PDP) Cycle 24A, as documented in the CBFO memorandum dated June 29, 2017. The systems met all PDP performance criteria and were approved for use without restriction. The four IWAS units are scheduled to participate in the CBFO-sponsored PDP annually. The EPA has no concerns regarding the AMWTP's participation in the CBFO-sponsored PDP.
The EPA confirmed that the AMWTP performed replicate testing of the Integrated Waste Assay Systems, and that all assays complied with the criteria for the U.S. Environmental Protection Agency Replicate Testing Protocol.
The purpose of the replicate testing performed as part of this inspection is to provide the EPA with an independent means to verify that the IWAS units can provide reproducible results for the determination of the quantity of 10 WIPP-tracked radionuclides ([241]Am, [137]Cs, [238]Pu, [239]Pu, [240]Pu, [242]Pu, [90]Sr, [233]U, [234]U and [238]U) and the TRU alpha activity concentration. This is accomplished by having the IWAS units reassay drums they previously measured to demonstrate each system's ability to do the following:
 Produce results consistent with the reported TMU by comparing the sample standard deviation for a number of replicate measurements taken over several hours or days to the reported TMU.
 Provide reproducible results over longer periods of time, such as weeks or months, by comparing the results of the replicate measurements to the original reported values.
As part of this inspection, the EPA requested that the AMWTP reassay five drums that the EPA selected from a list of drums previously assayed on the Z-211-102 and Z-211-103 units. Container Nos. 10597312 and 10612378 were chosen for the Z-211-102 unit, and Container Nos. 10596959, 10597411 and 10610103 were chosen for the Z-211-103 unit. The AMWTP reassayed all chosen containers five times, and EPA compared the results to the original assay data. Two statistical tests, a χ[2] test and a t-test, were performed, and the raw data and results of the statistical analysis are included in Attachments D.1 through D.5. The χ[2] test, which is also known as the goodness-of-fit test or the chi-squared test for independence, is used to show how observed data compare with data we would expect to obtain according to a specific hypothesis. The EPA applied it in this instance to show whether the replicate measurements differed from the expected original measurement. The t-test is a statistical tool that is used to tell if two sets of data are statistically different from one another. The EPA applied it to the replicate data to see if there were statistically significant differences between the original assay values and the average of the five replicate measurements.
The χ[2] test for all replicate analyses showed that the observed variances in the replicate measurements are less than or equal to the reported uncertainties within the statistical limits of the test. The t-test for all replicate analyses also showed no statistically significant differences between the original assay values and the average of the five replicate measurements. The EPA had no issues relative to replicate testing for the Z-211-102 and Z-211-103 IWAS units performed for this inspection at the AMWTP.
The AMWTP was not able to adjust the drum-handling protocols for the Z-390 IWAS units because the AMWTP WMF-636 process involves crushing all drums post-assay, rendering them unavailable for reassay. Accordingly, the EPA chose to forego replicate testing for the Z-390-100 and Z-390-101 IWAS units.
Summary of Evaluation of Integrated Waste Assay System Units Z-211-102, Z-211-103, Z-390-100 and Z-390-101
Based on the results of this evaluation, the EPA has no technical issues or concerns with the four IWAS units for assaying CH TRU waste.
Retrieval Box Assay System
 The EPA assessed the design and operational history of the Retrieval Box Assay System and determined they were adequate.
The Pajarito Scientific Company RBAS is designated as AMWTP Instrument No. Z-212-105 and is located in Building WMF-639 at the AMWTP, the same building that houses the Z-211-102 and Z-211-103 IWAS units. The RBAS is also used to certify low-level radioactive waste and for "safety significant" assays, i.e., assays to determine the fissile gram equivalent content of containers before bringing them into Building WMF-676 for processing as facility feed. The RBAS has been operational at the AMWTP to certify low-level radioactive waste and determine fissile gram equivalent since 2004. The EPA originally approved the RBAS for CH TRU assays in 2015 (see EPA Air e-Docket No. EPA-HQ-OAR-2001-0012-0459; October 19, 2015).
The RBAS is an imaging passive neutron/active neutron measurement system supplemented by a high-purity germanium gamma detection system. The passive neutron and active neutron data are used in conjunction with gamma-based isotopic determinations using Fixed-Energy Response Function Analysis with Multiple Efficiencies to quantify specific radionuclides and/or determine an item's fissile gram equivalent. Isotopic information can also be provided by approved AK. Integration of the neutron and isotopic data for each item is performed off line by the RBAS WIPP Analysis Reporting Software for Expert Analysis. Neutron measurements are matrix sensitive, particularly with respect to an item's hydrogen content. Accordingly, active neutron and passive neutron assays are typically discussed in terms of absorber indices for active neutron and moderator index for passive neutron. These indices represent the RBAS's response to specific matrices and nuclear material loadings and are combined into an absorber-moderator index for active neutron assays, while the moderator index is used for passive neutron assays, as discussed in section 6.3.1. 
The EPA has no concerns regarding the description, history or proposed application of the RBAS at the AMWTP for assaying CH TRU wastes.
New equipment or substantive physical modifications to approved equipment remains a Tier 1 change (see Table 1). Notification to the EPA upon substantive modification to software for approved NDA equipment remains a Tier 2 change (see Table 1).
The EPA verified that system calibrations for the Retrieval Box Assay System have been performed as required and are appropriate for the waste matrices the system will measure.
The RBAS had been calibrated initially at the Pajarito Scientific Company factory in Nashville, Tennessee, in 2001, as documented in the RBAS calibration test report/site acceptance test report PSC-5431-CRR-001. The AMWTP used [252]Cf sources for the passive neutron mode calibration and depleted uranium sources for the active neutron calibration, in conjunction with surrogate matrices in a fiberglass reinforced plastic (FRP) box. Certificates for the [252]Cf and depleted uranium sources are provided in Appendix 7 to PSC-5431-CRR-001. The [252]Cf sources were commercially available from Frontier Technology Corporation and were traceable to the national standards base [i.e., the National Institute of Standards and Technology (NIST)]. Robert Marshall's group at Los Alamos National Laboratory certified the fourteen depleted uranium sources for radionuclide content and traceability in 1991. The [252]Cf sources for passive neutron calibration represent a [240]PuEFF mass of approximately 11.55 g, equivalent to 194.05 g WG Pu. The [240]PuEFF provides a basis for comparing passive neutron measurements because it includes all even-numbered Pu isotopes. 
The depleted uranium sources used for active neutron calibration represented 0.862 g [239]PuEFF, a useful basis for comparing active neutron measurements because it includes all fissile radionuclides (i.e., [239]Pu, [233]U and [235]U). Each [252]Cf and depleted uranium source was measured twice at 42 reference points in a fiberglass reinforced plastic box for a total of 84 measurements. All radionuclide sources were appropriately documented and are appropriate for calibration of a passive and active neutron system.
Before beginning WIPP assays, the AMWTP amended the original RBAS calibration by adding metals and mixed debris (organic/inorganics), both of which required new absorber-moderator index values, as described in PSC-5431-CCR-001. This addition required adjusting the active neutron assay configuration for debris in Standard Waste Boxes to better match the matrix and absorber-moderator index values. Specifically, a manual override for active neutron assays for box size is recommended, while passive neutron assays are still selected automatically. A specific matrix selection has also been identified for sludge waste in 55-gallon drums inside a Standard Waste Box. Additionally, the active neutron threshold for [239]PuEFF was set such that any measured value greater than 8 g [240]PuEFF would be based on the passive neutron response. Both changes were technically adequate and appropriately documented in PSC-5431-CCR-001.
Fixed-Energy Response Function Analysis with Multiple Efficiencies typically provides statistically valid isotopic data for mass loadings above approximately 10 g total Pu. The RBAS WIPP Analysis Reporting Software for Expert Analysis software usually selects AK-based isotopics for values below 10 g of total Pu. Specific AK default parameter sets in the RBAS library provide values for [238]Pu, [239]Pu, [24][0]Pu, [241]Pu, [242]Pu and [241]Am for weapons grade and heat source Pu. The AMWTP evaluated the accuracy of Fixed-Energy Response Function Analysis with Multiple Efficiencies gamma data for three Pu standards at 8.9, 74.7 and 157.1 g of total Pu. Results of the analysis are shown in PSC-5431-CCR-001, Table 10.25. All results were acceptable.
The EPA has no concerns regarding the technical adequacy and documentation of the RBAS passive and active mode calibrations.
Extension of or changes to approved calibration ranges for approved equipment is a T1 change (see Table 1). Notification to the EPA upon changes to the approved operating ranges of approved NDA systems upon CBFO approval is a T2 change (see Table 1).
Notification to the EPA upon changes to RBAS procedures that require CBFO approval is a T2 change (see Table 1).
The EPA verified that determination and documentation for the total measurement uncertainty of assays performed by the Retrieval Box Assay System are adequate.
The AMWTP determined the TMU for the RBAS initially in 2002 and modified it most recently in 2004, as documented in BII-5112-TMU-001, Revision 2. The determination used NIST-traceable Pu sources assayed in a fiberglass reinforced plastic box and included the contributions of the following components for passive neutron and active neutron assays:
 Random error
 Background effects
 Matrix effects (heterogeneous and homogeneous)
 Neutron or gamma interferences
 Source distribution
 Box size effects
 Self-shielding, absorption and neutron multiplication
 Calibration uncertainties
The contributions of these components were added in quadrature, based on the assumption that all sources of error are independent. 
The AMWTP's determination of TMU for the RBAS was technically adequate and appropriately documented. The EPA has no concerns regarding the TMU determination for assaying CH TRU waste.
The EPA confirmed that the AMWTP's determination and documentation of the lower limit of detection, including the minimum detectable concentration, of the Retrieval Box Assay System was technically adequate.
The LLD for the RBAS is a function of the item's weight and the absorber-moderator index for absorber-moderator index active neutron assays and the moderator index for passive neutron assays; as such, it is complex. However, the criterion of interest is whether the RBAS has adequate sensitivity to support a TRU determination at the 100 nCi/g criterion. The AMWTP performed a series of replicate measurements with a variety of surrogate matrices in Standard Waste Boxes, fiberglass reinforced plastic and shredder boxes for both active neutron and passive neutron assays to establish and document that the RBAS had the required sensitivity.
The AMWTP determined the LLD for [238]Pu, [239]Pu, [240]Pu, [241]Pu, [242]Pu and [241]Am for both active neutron and passive neutron assays, for all measurement configurations, as shown in PSC-5431-CRR-001, Figure 8.2 and Figure 8.3. For the other WIPP-tracked or significant radionuclides, the AMWTP developed minimum detectable activity equivalent values (ratios) relative to Pu; minimum detectable activity values of zero will be reported for [234]U and [90]Sr.
The EPA has no concerns regarding the ability of the RBAS to sort TRU and non-TRU waste at the 100 nCi/g criterion.
The EPA assessed personnel training and found it to be adequate.
All AMWTP personnel associated with the calibration, operation, data review and approval of the RBAS had current training, as evidenced by the screenshot of the qualifications/certifications database dated July 24, 2017, that the AMWTP provided to the EPA before the inspection. The EPA has no concerns regarding the training of AMWTP RBAS NDA personnel.
Submission to the EPA of a list of all NDA personnel who performed work during the previous quarter remains an NDA Tier 2 change (see Table 1). Specifically, the list must include all RBAS operators, Expert Analysts and Independent Technical Reviewers.
The EPA established that the RBAS successfully participated in the Carlsbad Field Office-sponsored Performance Demonstration Program.
The RBAS successfully participated in the CBFO-sponsored PDP Cycle B16A, as documented in the CBFO memorandum dated October 20, 2016. The system met all performance criteria and was approved for use without restriction. The RBAS is scheduled to participate in the CBFO-sponsored PDP annually. The EPA has no concerns regarding the AMWTP RBAS's participation in the CBFO-sponsored PDP.
EPA replicate testing of the Retrieval Box Assay System was not performed. 
The EPA determined that replicates were not required as part of this inspection, based on the limited use of the RBAS for WIPP-certified assays. The EPA may request replicate analyses for the RBAS at a future inspection.
Summary of Evaluation of the Retrieval Box Assay System 
Based on the results of this evaluation, the EPA has no technical issues or concerns with the RBAS for assaying CH TRU wastes.
SWEPP Gamma-Ray Spectrometer
 The EPA verified that the design and essential functions SWEPP Gamma-Ray Spectrometer were adequate and that neither had changed for several years.
The SGRS was initially operated under the INL-CCP waste characterization program, and was transitioned to the AMWTP in October 2015. At that time, the EPA inspected the AMWTP TRU waste characterization program with the newly-acquired characterization equipment and processes, including the SGRS, and approved the program for characterizing CH TRU wastes for WIPP. Documentation for the SGRS's design, initial calibration and performance testing is provided by INL-CCP records, and these serve as the system's calibration of record. Accordingly, the EPA's technical evaluation of the system's design, initial calibration and performance testing occurred during the 2015 continued compliance inspection (see EPA E-DOCKET NO. EPA-HQ-OAR-2001-0012-0466). 
Between June 1, 2016, and August 11, 2017, the SGRS assayed 7,395 drums. The EPA inspectors observed the assay of Drum No. 10568514, which was one of the replicates selected by the EPA. For this baseline inspection, the EPA technical personnel reviewed the more recent INL-CCP records that reflected the system's design and performance history and indicate its continued adequacy for assaying CH TRU wastes. The EPA determined that the design and essential functions of the SGRS were technically adequate and appropriately documented in AMWTP documents.
New equipment or substantive physical modifications to approved equipment remains a Tier 1 change (see Table 1). Notification to the EPA upon substantive modification to software for approved NDA equipment remains a Tier 2 change (see Table 1).
The EPA verified that the calibration of the SWEPP Gamma-Ray Spectrometer was adequate for the wastes that the AMWTP currently assays and noted that the system has had no major changes apart from routine maintenance.
The EPA verified that the system's calibration was unchanged since the last inspection. The AMWTP performed a calibration verification in the last year after replacing Detector 4, documented in Work Order 510249. All aspects of the calibration verification were technically acceptable and appropriately documented.
The EPA has no concerns regarding the calibration of the SGRS NDA system.
Extension of or changes to approved calibration ranges for approved equipment is a Tier 1 change (see Table 1). Notification to the EPA upon changes to the approved operating ranges of approved NDA systems upon CBFO approval is a Tier 2 change (see Table 1).
Notification to the EPA upon changes to SGRS procedures that require CBFO approval is a Tier 2 change (see Table 1).
The EPA verified that determination and documentation for the total measurement uncertainty for the SWEPP Gamma-Ray Spectrometer are adequate.
The AMWTP documented the technical basis and derivation of TMU for assays performed on the SGRS in CCP-INL-SGRS-002, as required. The EPA Inspection Team verified that this document was technically adequate, addressed all appropriate contributors to the system's TMU and that it was unchanged since its initial publication in 2005.
The EPA has no concerns regarding TMU for the SGRS NDA system.
The EPA confirmed that the AMWTP's determination and documentation of the lower limit of detection, including the minimum detectable concentration, of the SWEPP Gamma-Ray Spectrometer was technically adequate.
Instruments performing TRU/non-TRU waste discrimination must have a minimum detectable concentration of less than 100 nCi/g of TRU radionuclides. Minimum detectable activities are instrument specific and depend on measurement conditions such as background rate and matrix. CCP-INL-SGRS-001, Revision 1, April 2008, adequately documents the technical basis for the system's LLD, including reporting thresholds for specific non-measured radionuclides [242]Pu and [90]Sr. The EPA Inspection Team verified that this document is applicable under the AMWTP waste characterization program and that the SGRS has adequate sensitivity to sort TRU/non-TRU wastes at 100 nCi/g.
The EPA has no concerns regarding the determination of the LLD for the SGRS NDA system.
The EPA assessed personnel training and found it to be adequate.
All AMWTP personnel associated with the calibration, operation, data review and approval of the SGRS had current training, as evidenced by the screenshot of the qualifications/certifications database dated July 24, 2017, that was provided prior to the inspection. There were no concerns regarding the training of AMWTP SGRS personnel.
Submission to the EPA of a list of all NDA personnel who performed work during the previous quarter remains an NDA Tier 2 change (see Table 1). Specifically, the list must include all SGRS operators, Expert Analysts and Independent Technical Reviewers.
The EPA established that the SWEPP Gamma-Ray Spectrometer successfully participated in the Carlsbad Field Office-sponsored Performance Demonstration Program.
The SGRS successfully participated in the CBFO-sponsored PDP, Cycle 24A. The system met all performance criteria and was approved for use without restriction. The SGRS is scheduled to participate in the CBFO-sponsored PDP annually. The EPA has no concerns regarding the AMWTP SGRS participation in the CBFO-sponsored PDP.
The EPA verified that the replicate testing of the SWEPP Gamma-Ray Spectrometer, complied with the criteria for the U.S. Environmental Protection Agency Replicate Testing Protocol.
The purpose of the replicate testing performed as part of this inspection is to provide the EPA with an independent means to verify that the SGRS can provide reproducible results for the determination of the quantity of 10 WIPP-tracked radionuclides ([241]Am, [137]Cs, [238]Pu, [239]Pu, [240]Pu, [242]Pu, [90]Sr, [233]U, [234]U and [238]U) and the TRU alpha concentration. This is accomplished by the SGRS reassaying drums it previously measured to demonstrate the system's ability to do the following:
 Produce results consistent with the reported TMU by comparing the sample standard deviation for a number of replicate measurements taken over several hours or days to the reported TMU.
 Provide reproducible results over longer periods of time, such as weeks or months, by comparing the results of the replicate measurements to the original reported values.
As part of this inspection, the EPA requested that the AMWTP reassay three drums that the EPA randomly selected from a list of drums previously assayed on the SGRS. Drum Nos. 10568514, 10565693 and 10566849 were reassayed five times, and the results were compared to the original assay data. Two statistical tests, a χ[2] test and a t-test as described in section 6.3.1, were performed. Data and results of the statistical analysis are included in Attachments H.1 through H.3.
For Drum Nos. 10565693 and 10566849, the χ[2] test showed that the observed variances in the replicate measurements are less than or equal to the reported uncertainties within the statistical limits of the test. The t-test for Drum Nos. 10565693 and 10566849 also showed no statistically significant differences between the original assay values and the average of the five replicate measurements.
All χ[2] values for the replicate measurements of Drum No. 10568514 were not significant. However, the t-test for [238]Pu was highly significant, while the remaining values were not significant. The primary isotope measured by direct gamma was [239]Pu. Measured isotopic ratios were used to calculate activities for [238]Pu, [240]Pu, [241]Pu and [242]Pu. There was variability in the Multi-Group Analysis results between the original and the average of the replicate measurements. The original measurement had a measured isotopic ratio for [238]Pu that was less than the values for all replicate measurements, which resulted in a highly significant t-test for [238]Pu. This is more an artifact of the statistical evaluation and does not represent a true measurement issue. The overall assay results are acceptable.
Summary of Evaluation of the SWEPP Gamma Ray Spectrometer 
Based on the results of this evaluation, the EPA has no technical issues or concerns with the SGRS for assaying CH TRU wastes.
Waste Assay Gamma System
 The EPA verified that the design and essential functions of the Waste Assay Gamma System were technically adequate and that neither had changed for several years.
 The WAGS was initially operated under the INL-CCP waste characterization program, and was transitioned to the AMWTP in October 2015. At that time, the EPA inspected the AMWTP TRU waste characterization program with the newly-acquired characterization equipment and processes, including the WAGS, and approved the program for characterizing CH TRU wastes for WIPP. Documentation for the WAGS's design, initial calibration and performance testing is provided by INL-CCP records, and these serve as the system's calibration of record. Accordingly, the EPA's technical evaluation of the system's design, initial calibration and performance testing occurred during the 2015 continued compliance inspection (see EPA DOCKET NO. A-98-49; II-A4-206 or EPA E-DOCKET NO. EPA-HQ-OAR-2001-0012-0466). 
Between June 1, 2016, and August 9, 2017, the WAGS assayed 3,651 containers. The instrument was idle on the day of inspection due to a lack of containers to assay; however, the system's status was operable, and the EPA was able to evaluate its performance.
The EPA reviewed the electronic WAGS logbook and batch data report Nos. ASY16-04097 and ASY16-03498 and found them to adequately document drum assays. The EPA observed objective evidence that WAGS operators appropriately recorded all daily performance measurements and that all checks were within acceptance criteria. Specifically, WAGS operators evaluated background, daily performance check, full width at half maximum, energy calibration (gain) and [133]Ba transmission source checks. The AMWTP had established and documented warning and control limits, 2 and 3 sigma (σ) limits, respectively, for all parameters, as appropriate, and boundary limits for full spectrum background of ~40 counts per second, full width at half maximum and amplifier gain.
Due to the approximately 10-year half-life of [133]Ba, the software decay corrects the [133]Ba transmission to adjust the count rate boundary limits throughout their operational lives. The EPA observed WAGS personnel using the current revisions of the WAGS operating procedure. All operational aspects of the WAGS operation were acceptable. The EPA verified that the operational range of the WAGS was adequate for the wastes that the AMWTP currently assays.
New equipment or substantive physical modifications to approved equipment remains a Tier 1 change (see Table 1). Notification to the EPA upon substantive modification to software for approved NDA equipment remains a Tier 2 change (see Table 1).
The EPA verified that the calibration of the Waste Assay Gamma System was adequate and noted that there were no major system changes apart from routine maintenance.
The EPA verified that the system's calibration was adequate for the type of CH TRU wastes that the AMWTP assays with the WAGS, and that the calibration had not been changed for several years. The AMWTP did perform one calibration verification in the last year after replacing BEGe detectors Nos. 2 and 5, which was documented in an AMWTP Work Order, which did confirm the existing calibration. All aspects of the WAGS calibration verification were technically acceptable and appropriate documented. 
The EPA has no concerns regarding the calibration of the WAGS NDA system.
Extension of or changes to approved calibration ranges for approved equipment is a Tier 1 change (see Table 1). Notification to the EPA upon changes to the approved operating ranges of approved NDA systems upon CBFO approval is a Tier 2 change (see Table 1).
Notification to the EPA upon changes to WAGS procedures that require CBFO approval is a Tier 2 change (see Table 1).
The EPA verified that the AMWTP documented the total measurement uncertainty of assays performed on the Waste Assay Gamma System, and that they were technically adequate and appropriately documented. 
The AMWTP documented the technical derivation for TMU of assays performed on the WAGS in CCP-WAGS-002, and the EPA verified that the TMU document was technically adequate, included all appropriate contributors to uncertainty and was unchanged since its initial publication in 2005. The EPA reviewed WAGS batch data report Nos. ASY16-04097 and ASY16-03498 and found the TMU values consistent with CCP-WAGS-002 and adequate for CH TRU wastes.
The EPA has no concerns regarding the technical adequacy or documentation of TMU of the AMWTP WAGS NDA system.
The EPA confirmed that the AMWTP's determination and documentation of the lower limit of detection, including the minimum detectable concentration, of the Waste Assay Gamma System was technically adequate.
The EPA Inspection Team verified that CCP-INL-WAGS-001, Revision 1, April 2008, adequately documents the technical basis for the system's LLD, including reporting thresholds for the specific non-measured radionuclides [242]Pu, [234]U and [90]Sr.
The EPA has no concerns regarding the AMWTP's determination and documentation of the LLD for the WAGS NDA system.
The EPA assessed personnel training and found it to be adequate.
All AMWTP NDA personnel associated with the calibration, operation, data review and approval of the WAGS had current training, as evidenced by the list of employees by qualifications/certifications dated July 24, 2017, that the AMWTP provided before the inspection. The EPA has no concerns regarding the training of AMWTP personnel.
Submission to the EPA of a list of all NDA personnel who performed work during the previous quarter remains an NDA Tier 2 change (see Table 1). Specifically, the list must include all NDA operators, Expert Analysts and Independent Technical Reviewers.
The EPA established that the Waste Assay Gamma System successfully participated in the Carlsbad Field Office-sponsored Performance Demonstration Program.
 The WAGS successfully participated in the CBFO-sponsored PDP, Cycle 24A, as documented in the CBFO memorandum dated June 29, 2017. The system met all performance criteria and was approved for use without restriction. The WAGS is scheduled to participate in the CBFO-sponsored PDP annually. The EPA has no concerns regarding participation of the AMWTP WAGS in the CBFO-sponsored PDP.
EPA replicate testing of the Waste Assay Gamma System was not performed. 
For logistical reasons, the EPA determined that replicates were not required as part of this inspection. The EPA may request replicate analyses for the WAGS at a future inspection.
Summary of Evaluation of the Waste Assay Gamma System 
Based on the results of this evaluation, the EPA has no technical issues or concerns with the WAGS for assaying CH TRU wastes
Nondestructive Assay Conclusion
Changes to Tiering
During an inspection, the EPA evaluates an NDA system's technical capabilities, and these define the operational envelope in which WIPP measurements will occur. Changes to a system's operation with respect to its ability to measure activity and/or waste matrices may represent a different set of conditions from those that EPA evaluated and approved during the inspection. For this reason, certain system changes are Tier 1 changes. Other less significant but still important changes are designated as Tier 2 changes.
Based on the NDA inspection and the results discussed above, the EPA assigns the following AMWTP items or actions as Tier 1 changes that will require EPA review and approval prior to implementation:
 New NDA equipment: A system or component not previously evaluated by the EPA. Specifically, this is defined as a physically distinct or different system or apparatus. An assay system that is reported to be the equivalent of or identical to a previously approved system but that has not been formally inspected and approved by the EPA is a new system and must be approved by the EPA prior to implementation to characterize WIPP wastes.

 Physical modifications to approved equipment: Changes to existing NDA equipment include all changes and/or modifications to approved equipment that have the potential to affect the quality of NDA data used for the purposes of waste characterization and/or waste isolation. This does not include minor or safety-related changes (e.g., addition of hand rails) that do not have the potential to affect waste characterization data.

 Extension or changes to an approved calibration range for approved equipment: Those changes that affect the determination of activity or matrix of any of the seven NDA systems proposed for approval during this inspection. Examples of changes in this category include changing a system's operating system (e.g., first use of Canberra NDA 2000), identification of a systematic problem with a software package and subsequent modifications to address the problem (e.g., use of an incorrect value for a radionuclide's transition probability in NDA 2000), and introduction of a new version of an existing software package beyond what is in current use. 

T2 NDA changes that do not require EPA approval prior to implementation but require reporting and submission of documentation discussing changes by the AMWTP include the following:
 Changes to software for approved equipment that do not affect the determination of activity or matrix by an NDA system
 Changes to the approved operating ranges of approved NDA systems upon CBFO approval
 Changes to procedures that require CBFO approval
Summary of Nondestructive Assay Findings and Concerns
The EPA did not identify any findings or concerns for any of the seven NDA units at the AMWTP. 
Proposed Nondestructive Assay Baseline Approval
The NDA baseline conditions that the EPA Inspection Team evaluated consist of the seven NDA systems described in this report.
The EPA is proposing to approve each NDA system, along with its range of applicability for activity and matrix, and any limitations, as described in this report and detailed in the NDA checklists (Attachments D, E, F, G and H). The EPA has found the NDA procedures, personnel and equipment evaluated at the AMWTP during this inspection to be acceptable for this waste characterization element.
Real-Time Radiography (RTR)
Waste Characterization Element Description
The EPA evaluated the documentation that the AMWTP prepared to support the RTR process to characterize CH TRU wastes using three RTR units, RTR Unit Nos. Z-213-101, Z-213-106 and 1001. The EPA had previously approved these RTR units for SCG S5000 and S3000 wastes. The Z-213-101 and Z-213-106 RTR units were approved under the AMWTP's TRU characterization program, and the No. 1001 RTR unit was approved under the INL-CCP TRU characterization program. 
This baseline inspection consisted of reviewing technical records and batch data reports, which, as with all AMWTP records, exist in electronic format only. The EPA Inspection Team prepared an inspection checklist (see Attachment I) that included the aspects of the RTR systems described below. This was followed by an onsite inspection of the RTR units, including observation of the RTR process for the 1001 RTR unit and one of the WMF-634 units, Z-213-106, focusing on the following: 
       Capability of the RTR hardware and software to perform the required analyses
       Technical adequacy of the NDE documents and procedures to support the AMWTP's RTR operation to characterize CH TRU wastes
       Knowledge, understanding and training of the personnel involved in the AMWTP program 
The EPA evaluation included the aspects listed below.
 The EPA evaluated the operation of the AMWTP real-time radiography units and established that they are technically adequate for nondestructive examination of CH TRU wastes, and that they are the same units that the EPA had approved previously.
The Z-213-101 and Z-213-106 RTR units are co-located located in Building WMF-634 at the AMWTP, the same building as the IWAS and RBAS NDA systems described in sections 6.3.1 and 6.3.2 of this report. The No. 1001 RTR Unit is located in the SWEPP at INL, in the same building as the WAGS and SGRS NDA systems described in sections 6.3.3 and 6.3.4 of this report. EPA technical personnel confirmed that the EPA had approved these RTR units previously, as discussed in sections 6.3.3.and 6.3.4 of this report, and that none of them had been moved or substantially modified since their previous EPA evaluations. 
The EPA evaluated the technical specifications of the units and the detailed instruction for performing RTR, as documented in AMWTP Procedure TPR-8089, and for data validation, documented in AMWTP Procedures MCP-4005 and MCP-4006. The EPA determined that the Z-213-101, Z-213-106 and 1001 RTR units were technically adequate for x-ray radiographic examination of the CH TRU wastes that the AMWTP intends to characterize and ship to the WIPP. The EPA also determined that the operating and data validation procedures were adequate. The EPA had no concerns regarding the operation of the AMWTP RTR units.
New RTR equipment or substantive physical modifications to approved RTR equipment are new Tier 1 changes (see Table 1). Submission to the EPA of a list of AMWTP RTR operators and Independent Technical Reviewers that performed work during the previous quarter and notification to the EPA upon substantive modification to site procedures requiring CBFO approval are new Tier 2 changes (see Table 1).
 The EPA observed the examined real-time radiography process and determined it was adequate.
The EPA observed AMWTP personnel execute the RTR process using two of the three RTR units, as described below. The AMWTP considers the Z-213-101 and Z-213-106 RTR units to be equivalent, and they perform the majority of the RTR events used for WIPP certification. The EPA chose to observe the RTR process using the Z-213-106 RTR unit, because it was operational at the time of this inspection. The 1001 RTR unit is older and is used less frequently for WIPP certification; the EPA also observed the operation of this RTR unit.
RTR Unit Z-213-106
The EPA observed AMWTP personnel operate the Z-213-106 RTR unit using AMWTP Procedures TPR-8089 and TPR-8086 on Container No. 10624612, a 55-gallon drum in an 85-gallon overpack, from RTR Batch No. RTR17-00136. The Z-213-101 RTR unit can accept up to four containers; this container was in position No. 2. The RTR operator performed Image Quality Indicator No. 080912IQI1010 before examining drums after system startup and provided documentation that an independent replicate scan had been performed for this batch. The Image Quality Indicator contained all pertinent information and was reviewed and approved by the Shift Supervisor on AMWTP Form No. 1578. A second AMWTP RTR operator reviewed the replicate scan and found it to be acceptable. The audiovisual record of this scan is stored in RTR File Number 1RTR17-00206.
Using the controls, the RTR operator manipulated the drum and examined its contents, noted that the container had a fill factor of 80% and initiated two nonconformance reports (NCRs) for this container. NCR No. 113071 was initiated for the presence of a prohibited item, an aerosol can. NCR No. 113073 was initiated for liquid observed in two places in the drum, at the bottom of the drum and in a plastic bag at mid-height in the drum. AMWTP personnel changed monitor screens to initiate the NCRs, attached the appropriate forms to the container's record and physically affixed a tag to the container upon completion of the RTR event.
RTR Unit 1001
The EPA observed AMWTP personnel operate the RTR-1001 unit for Container No. 10624626, which had a previous RTR examination, documented in batch data report No. RTR-17-00002. The AMWTP performed this RTR event during this inspection for demonstration purposes; this was not intended to be used for WIPP certification. The RTR operator used AMWTP Procedures TPR-8089 and TPR-8120 and performed an Image Quality Indicator and replicate scan before beginning the RTR event. Using the controls, the RTR operator manipulated the drum, examined its contents and determined that the drum's contents were impenetrable, which was consistent with the previous RTR event, requiring the initiation of an NCR to change the container's waste matrix code assignment to 5490, as detailed in RPT-TRUW-05. The AMWTP RTR operator determined and recorded the drum's fill height and recorded all pertinent RTR characterization data electronically.
The EPA determined that the AMWTP RTR process was technically adequate and appropriately documented. The EPA had no concerns regarding the AMWTP's execution of the RTR process.
 The EPA examined real-time radiography batch data reports and found they were adequate.
The AMWTP provided documentation for four RTR batch data reports to support the EPA's review for this baseline inspection. This included the completed batch data report Nos. RTR-17-00111, RTR-16-00176, RTR-17-00009 and RTR-17-00140, and the audiovisual copy of each examination. The batch data reports contained all required elements; a list of these items is provided with the RTR checklist (see Attachment I).
The EPA determined that the records for RTR at the AMWTP were acceptable and that they appropriately documented the RTR process for CH TRU waste that the AMWTP intends to ship to the WIPP. The EPA had no concerns regarding the AMWTP's documentation of the RTR process.
 The EPA examined real-time radiography training records and found them to be adequate.
The AMWTP provided a list of all AMWTP personnel trained for RTR, including 22 RTR Operators and nine Level 1 Independent Technical Reviewers, all of whom were qualified in accordance with MCP-4026. The EPA reviewed the written and audiovisual training records for selected AMWTP RTR personnel. The training records included:
 NDE training container inventory sheets for RTR training drums
 Training container evaluation data sheets
 Audiovisual recordings of training/test examinations
 RTR Qualification Package No. QPOT03A0
 AMWTP training records for dates covering the time period when AMWTP batch data report Nos. RTR-17-00111, RTR-16-00176, RTR-17-00009 and RTR-17-00140 were generated.
The EPA determined that operators were trained appropriately and that all RTR personnel were included on the list that the AMWTP provided during this baseline inspection. All hard-copy and electronic training records were readily available for the EPA's review. The EPA had no concerns regarding training for AMWTP RTR personnel.
Submission to the EPA of a list of all RTR personnel who performed work during the previous quarter is a new RTR Tier 2 change (see Table 1). Specifically, the list must include all RTR operators and Independent Technical Reviewers. This requirement ensures that the EPA has a complete picture of ongoing AMWTP RTR waste characterization activities, which will inform the scope of future EPA RTR evaluations.

Visual Examination (VE)
Waste Characterization Element Description
The AMWTP has three types of VE to support the characterization of WIPP CH TRU wastes. They are essentially the same process with respect to the procedural controls and types of documentation each requires; they differ only in the site where the examinations occur.
The AMWTP conducts VE inside the waste treatment building, Building WMF-676, covered under Procedure TPR-8041. The AMWTP refers to this as Facility VE, performed according to Procedure TPR-8041. It is conducted concurrently with AMWTP assembling waste containers in a separate area using remote equipment. Wastes in boxes or other containers are brought into the enclosed processing area in WMF-676, where they are emptied, sorted and placed in new 55-gallon drums using remote-handling equipment. AMWTP VE personnel conduct VE while the drums are being compiled. There were two AMWTP VE Experts for Facility VE, Lawrence J. Walker and Ron Grise.
The AMWTP also conducts VE at the Accelerated Retrieval Project (ARP) and Sludge Repackaging Project (SRP), which the AMWTP refers to as Visual Examination Activities at Radioactive Waste Management Complex, covered under AMWTP Procedure TPR-7997. The ARP and SRP are both areas of active waste removal within the Subsurface Disposal Area at the AMWTP, where personnel excavate wastes from essentially shallow land burial. All work occurs within enclosures (glovebox-like areas), in which wastes are removed, examined and loaded into new 55-gallon drums. AMWTP personnel conduct the VE of record as the wastes are examined and loaded into drums. There were two AMWTP Visual Examination Experts for ARP/SRP VE, Luke Grover and Matt Hudson.
The AMWTP refers to the third type as Non-Facility VE Operations, covered in AMWTP Procedure TPR-8103. This VE can occur anywhere onsite at the AMWTP, but the AMWTP typically conducts this type of VE in conjunction with Facility VE, described above. While conducting Facility VE, operators encounter items that must be removed and set aside. The usual AMWTP practice is to begin accumulating these items in a new 55-gallon drum, which remains open in the processing building (WMF-634) facility, until sufficient items have been accumulated to fill the drum. Upon closure, the drum is processed as newly-generated waste. Typically, this type of VE is performed under the direction of the Facility Visual Examination Experts, Lawrence J. Walker and Ron Grise.
All AMWTP VE procedures contain complete and detailed instructions for performing VE and require the operators to (1) document the waste's waste material parameters and the presence or absence of prohibited items and (2) verify the waste matrix code and waste item description code. All AMWTP VE data are electronically recorded in accordance with the instructions in the VE procedures.
The EPA evaluated the documentation that the AMWTP prepared to support the VE process to characterize CH TRU wastes, which the EPA had previously approved for SCG 3000, 4000 and 5000 wastes. This baseline inspection consisted of reviewing technical records and batch data reports, which, as with all AMWTP records, exist in electronic format only. The EPA Inspection Team members prepared a VE inspection checklist (see Attachment J), that included the aspects of VE described below. This was followed by an onsite inspection of facility VE and VE at the SRP, focusing on the following:
 Capability of the VE process to confirm the waste's waste material parameters, waste matrix code and item description code and document the presence or absence of prohibited items
       Technical adequacy of AMWTP documents and procedures to support VE operations to characterize CH TRU wastes
       Knowledge, understanding and training of AMWTP personnel performing VE for CH TRU wastes
The EPA T1 evaluation included the aspects listed below.
 The EPA observed the contact-handled visual examination process and found it to be technically adequate for visual examination of AMWTP contact-handled transuranic wastes.
The EPA observed VE operations in Room 231, north box-line, of Building WMF-676. Two VE operators sorted waste from Box No. 10623990, from AMWTP CH TRU Waste Stream BN-510, for packaging in 55-gallon Drum No. 1045147. The AMWTP performed VE in accordance with AMWTP Procedure TPR-8103, "Non-Facility Visual Examination Operations." From the facility control room, one operator manipulated the waste with a remote-control arm, while the other operator electronically entered data in an electric format. At the end of packaging, both operators verified the data entry and electronically signed off the data sheet. A Visual Examination Expert was present during the VE event, and all VE operations were technically adequate and appropriately documented.
The EPA also observed the AMWTP VE process at the SRP (also called ARP-5), in accordance with AMWTP Procedure TPR-7997, on Container No. 1617, an SCG S3100 inorganic sludge with an item description code of CW-126 and a net weight of 116.5 kilograms (~239 pounds). The process that the EPA observed consisted of the following steps:
 Unloading material removed from the disposal area into a large, sliding tray
 Sorting the sludge material to remove prohibited or nonconforming items
 Confirming the waste matrix code, waste material parameters and item description code
 Entering VE data electronically, including confirmation by a second AMWTP VE operator
 Radiation surveys conducted by AMWTP Health Physics staff
 Closing drum and tightening with a calibrated torque wrench
 Affixing the appropriate labels
 Weighing the drum on a precalibrated scale
Two AMWTP VE Operators and an AMWTP Visual Examination Expert were present at the VE event. All data were entered by one operator and confirmed by the second operator. The EPA technical inspectors had access to observe all aspects of the VE process at the SRP and viewed all data entry by AMWTP VE personnel.
The EPA had no concerns regarding the CH TRU VE characterization process for the AMWTP.
 The EPA examined visual examination characterization records and found them to be adequate.
The EPA reviewed the following VE batch data reports from VE activities at SRP, ARP and WMF-676:
 SRP batch data report Nos. VEAB-16-00159, VEAB-16-00016
 ARP batch data report Nos. ARP-15-00023, ARP-15-00028
 WMF-676 batch data report No. VNC-16-00019
The EPA determined that the VE batch data reports were complete, were technically adequate and contained all appropriate information to support VE for CH TRU wastes.
The EPA had no concerns regarding the CH TRU VE characterization records for the AMWTP.
 The EPA examined contact-handled visual examination training records and found them to be adequate.
Training for all AMWTP VE personnel was current, including readings/indoctrination and On-the-Job-Training practical requirements (Tailgate Briefings), based on qualification packages that the AMWTP provided for review during this baseline inspection. All VE operators and Independent Technical Reviewers were included on the formal AMWTP training/qualification listing. The EPA reviewed training records in detail for selected operators. The AMWTP provided a complete list of all VE operators, Visual Examination Experts and Independent Technical Reviewers that were qualified at the time of the baseline inspection. All AMWTP Visual Examination Experts had formal Visual Examination Expert appointment letters. The EPA determined that CH TRU VE personnel had adequate training and that their training records were complete and readily available for EPA inspection. 
Submission to the EPA of a list of all VE personnel who performed work during the previous quarter remains a VE T2 requirement (see Table 1). Specifically, the list must include all VE operators, Independent Technical Reviewers and Visual Examination Experts to ensure that the EPA has a complete picture of AMWTP waste characterization activities and potentially inform the scope of future EPA evaluations.
The EPA had no concerns regarding the CH TRU VE training records for AMWTP personnel.
Visual Examination Conclusion

Conclusions
This proposed approval is based on the EPA's baseline inspection conducted on August 8 - 10, 2017, in and near Idaho Falls, Idaho. The EPA evaluated the AMWTP's CH TRU waste characterization program and determined it to be technically adequate. The proposed approval includes:
       The AK process for AMWTP CH TRU waste, including the Enhanced AK process
       Four IWAS, the RBAS, the WAGS and the SGRS NDA systems for characterizing CH TRU waste
       The RTR process using three RTR units to identify waste material parameters and the physical form of CH TRU waste
       The VE process to identify waste material parameters and the physical form of CH TRU waste.
Any changes to the waste characterization activities from the date of the baseline inspection must be reported to and, if applicable, approved by the EPA, according to Table 1. All Tier 1 changes must be submitted for approval before their implementation and will be evaluated by the EPA. Upon approval, the EPA will post the results of the evaluations through the EPA website and the WIPPNEWS list. The AMWTP must submit Tier 2 changes that have been implemented four times a year, at the end of each fiscal quarter.

Nondestructive Assay Baseline Inspection Checklist:
Z-211 Integrated Waste Assay System (IWAS) Z-211-102 and Z-211-103 
EPA Inspection No.: AMWTP-Fluor 08.17-8	Inspection Date: August 8 - 10, 2017
                           Technical Element/Aspect
                                  Yes, No, NA
                        Comments and Objective Evidence
 General System Attributes
   
   
 Is the NDA system the Integrated Waste Assay System Z-211-102 and Z-211-103? Where is it located?
                                       Y
The IWAS Z-211-102 and Z-211-103 units are in WMF Building 634 at the AMWTP located on DOE's INL site. Confirmed by direct observation during the inspection.
 Describe the Integrated Waste Assay System Z-211-102 and Z-211-103. 
                                       Y
The Z-211-102 and Z-211-103 IWAS units assay CH retrievably-stored or newly-generated wastes in 55- and 85-gallon containers. For PN assays, each IWAS unit uses [3]He proportional counters in a 4Π geometry to detect [240]Pu or other spontaneous fission neutrons. The IWAS estimates the [240]PuEFF based on direct neutron measurement. Individual radionuclides can be estimated by combining the measured [240]PuEFF with ratios of other radionuclides measured with two BEGe gamma detectors. An AAS matrix-correction technique is correct for matrix effects. During the AAS measurement, a [252]Cf source is introduced into the drum measurement chamber. The response of the system to the [252]Cf source with the waste matrix present is compared with the recorded response of the system to the same source when no waste matrix is present, and a correction factor is derived from that ratio.
 System Performance
   
   
 Are the container types, types of TRU waste, and the operational parameters for the Integrated Waste Assay System Z-211-102 and Z-211-103 defined and reasonable? 
                                       Y
The Integrated Waste Assay System Z-211-102 and Z-211-103 IWAS units assay CH TRU waste in 55-gallon drums and 55-gallon/83-gallon overpacks. Both are capable of assaying a variety of waste matrices, including combustibles, glass, organic and inorganic sludge, and metals. Both systems are limited to assaying only debris, and debris and solids. Because of the multi-modal system design and the ability to correct for matrix effects on both the gamma and neutron measurement elements independently, the systems are essentially matrix-independent within the range of demonstrated applicability for each measurement technique.
 How many waste containers were assayed by the Integrated Waste Assay System Z-211-102 and Z-211-103?
                                       Y
The Z-211-102 assayed 4,463 and the Z-211-103 assayed 4,216 waste containers. At the time of assay, all containers were believed to be TRU; however, many drums do not meet the TRU waste criteria and fall out as LLW. Exact numbers were not provided by AMWTP personnel.
 Are the Integrated Waste Assay System Z-211-102 and Z-211-103 able to report quantitative values and uncertainties for the WIPP-tracked radionuclides?
                                       Y
Direct Measurements: [239]Pu, [238]Pu, [240]Pu, [241]Am, [233]U, [238]U and [137]Cs.
In the absence of sufficient gamma signal or other interference that prohibits the use of MGA, NDA 2000 uses default values for WG Pu or HS Pu as a function of the main radionuclide detected, i.e., [239]Pu or [238]Pu. Other gamma emitters may be measured directly and reported, when applicable.
[242]Pu is determined by correlation; [90]Sr and [234]U are scaled to [137]Cs and [235]U and/or [238]U, respectively.
Confirmed with NDA personnel during inspection.
 Have background measurements been taken each operational day? Have any instances of problematic background radiation been documented?
                                       Y
NDA BDRs that were evaluated contain evidence of the background performance for both systems.
 Have system performance checks been completed at least once per operational day? Are the procedures for the performance checks technically adequate for the Integrated Waste Assay System Z-211-102 and Z-211-103, including gamma matrix correction checks, and gamma peak position and resolution checks?
                                       Y
This was confirmed in the electronic logbook and with personnel in the operations area.
 System Calibration & Calibration Verifications
   
   
 Do the Integrated Waste Assay System Z-211-102 and Z-211-103 have a calibration of record? Were consensus standards used in the initial calibration? If so, which standards?
                                       Y
Both IWAS units were calibrated in Meriden, CT, prior to their shipment to the AMWTP. Upon receipt/installation at the AMWTP, calibrations were verified as documented in SATR CI-IDA-NDA-0051 and CI-IDA-NDA-0052. Calibrations for both IWAS units were done in accordance with CI-IDA-NDA-0031. AMWTP-RPT-TRUW-03, Revision 5, references consensus standards ASTM C1030, ASTM C1207 and ASTM C1316.
 Are the calibration, execution of performance checks and operation of the Integrated Waste Assay System Z-211-102 and Z-211-103, the calculation of radionuclide values and the review/validation of Integrated Waste Assay System Z-211-102 and Z-211-103 data governed by controlled-copy (formal) procedures?
                                       
Verification of the instruments' calibration has been performed many times, as documented on the summary provided by J. Seamans, including routine maintenance and replacement of the gamma detector(s).
 Are the current revisions of procedures in use for the Integrated Waste Assay System Z-211-102 and Z-211-103?
                                       
Operations procedures are available as hard copies in the control room. All other procedures were available digitally to the operators, all procedures are current and copies of each were found and easily accessible in the control room for the Z-211-102 and Z-211-103 systems.
 Are the isotopic contributions of unmeasured radionuclides derived using a certain method?
                                       
[241]Am and Pu isotopics are determined by FRAM software; site-approved AK is used for default isotopics. Confirmed with AMWTP NDA personnel during evaluation.
 Were traceable radionuclide sources used for calibration confirmation and/or verifications?
                                       
As verified in Work Order dated June 21, 2017
 Have the operational ranges with respect to matrix (density) and activity been determined for the Integrated Waste Assay System Z-211-102 and Z-211-103? 
                                       
Operating ranges are specified in SATRs CI-IDA-NDA-0051 and CI-IDA-NDA-0052. The IWAS calibrations are not mass calibrations in a strict sense, although the AMWTP expresses the operating range as 0.010 g - 200 g WG Pu. In theory, any assay within energy range for gamma or AAS range for PN that meets measurement criteria is acceptable.
Matrices used for AN and PN calibration include combustibles, glass, organic and inorganic sludges (solids), and metals. For gamma mode, matrices with densities up to 1.6 g/cm[3] were used. Matrices for all operational modes are representative with respect to physical form and activity.
 Have calibration verifications been completed for the Integrated Waste Assay System Z-211-102 and Z-211-103? If so, what is the date of the last calibration verification? Have any others been completed in the last year?
                                       
As verified in Work Order associated with system Z-211-102 dated June 21, 2017. Both BEGe detectors replaced.

 Operator and reviewer signatures?
                                       
The EPA reviewed IWAS Z-211-102 and Z-211-103 BDRs to confirm they contain appropriate information. All necessary information is provided.
 Total Measurement Uncertainty
   
   
 Is the magnitude of the TMU values observed in the Integrated Waste Assay System Z-211-102 and Z-211-103 BDRs examined during the inspection within the expected range?
                                       
Confirmed TMU determination is the same for both Z-211 IWAS units, and both are documented in CI-IDA-NDA-0055, TMU for the AMWTP Integrated Waste Assay System, Revision 1, July 30, 2003.
 Lower Limit of Detection
   
   
 Has the LLD for the Integrated Waste Assay System Z-211-102 and Z-211-103 been determined? Is the LLD determination appropriate for the types of TRU waste the AMWTP expects to assay on the Integrated Waste Assay System Z-211-102 and Z-211-103? Is the technical basis for the LLD determination documented?
                                       
LLDs are determined for each assay modality measurement. Nominal values are reported in the Site Acceptance Test Reports CI-IDA-NDA-0051 and CI-IDA-NDA-0052 for Z-211-102 and Z-211-103, respectively.
 Are the Integrated Waste Assay System Z-211-102 and Z-211-103 used to discriminate TRU/Non-TRU wastes at the 100 nCi/g criterion? If so, do the Integrated Waste Assay System Z-211-102 and Z-211-103 have the required sensitivity? 
                                       
SATRs CI-IDA-NDA-0051 and CI-IDA-NDA-0052 for Z-211-102 and Z-211-103, respectively.
 Are there any instances where an LLD value for a non-measured radionuclide is not provided based on a lack of technical feasibility?
                                       
Several BDRs show concentrations near the LLD however this is associated with LLW drums.

Nondestructive Assay Baseline Inspection Checklist:
Z-390 Integrated Waste Assay System (IWAS) Z-390-100 and Z-390-101
EPA Inspection No.: AMWTP-Fluor 08.17-8	Inspection Date: August 8 - 10, 2017
                           Technical Element/Aspect
                                  Yes, No, NA
                        Comments and Objective Evidence
 General System Attributes
   
   
 Is the NDA system the Integrated Waste Assay System Z-390-100 and Z-390-101? Where is it located?
                                       Y
EPA inspectors found the IWAS Z-390-100 and Z-390-101 units are located in Building 676 at the AMWTP at DOE's Idaho National Laboratory site. Confirmed during inspection.
 Describe the Integrated Waste Assay System Z-390-100 and Z-390-101. 
                                       Y
The Z-390-100 and Z-390-101 IWAS units assay CH retrievably-stored or newly-generated wastes in 55- and 85-gallon containers. For PN assays, each IWAS unit uses [3]He proportional counters in a 4Π geometry to detect [240]Pu or other spontaneous fission neutrons. The IWAS estimates the [240]PuEFF based on direct neutron measurement. Individual radionuclides can be estimated by combining the measured [240]PuEFF with ratios of other radionuclides measured with two BEGe gamma detectors. An AAS matrix-correction technique is correct for matrix effects. During the AAS measurement, a [252]Cf source is introduced into the drum measurement chamber. The response of the system to the [252]Cf source with the waste matrix present is compared with the recorded response of the system to the same source when no waste matrix is present, and a correction factor is derived from that ratio.
 System Performance
   
   
 Are the container types, types of TRU waste and the operational parameters for the Integrated Waste Assay System Z-390-100 and Z-390-101 defined and reasonable? 
                                       Y
The IWAS Z-390-100 and Z-390-101 units are capable of assaying the radiological components of TRU waste in 55-gallon drums. Both are capable of assaying a variety of waste matrices, including combustibles, glass, organic and inorganic sludge, and metals. Both systems are limited to assaying only debris wastes. Because of the multi-modal system design and the ability to correct for matrix effects on both the gamma and neutron measurement elements independently, the systems are essentially matrix-independent within the range of demonstrated applicability for each measurement technique.
 How many waste containers were assayed by the Integrated Waste Assay System Z-390-100 and Z-390-101?
                                       Y
Z-390-100 assayed 7,121 drums, and Z-390-101 assayed 5,205 drums since June 1, 2016. Z-390-101 had less use because the conveyer that feeds the system was broken for approximately a month.
	
 Are the Integrated Waste Assay System Z-390-100 and Z-390-101 able to report quantitative values and uncertainties for the WIPP-tracked radionuclides?
                                       Y
The Z-390 systems provide quantitative values and uncertainties for [238]Pu, [239]Pu, [240]Pu, [242]Pu, [241]Am, [233]U, [234]U, [238]U, [90]Sr and [137]Cs.
Site Acceptance Test Reports CI-IDA-NDA-0053 and CI-NIDA-NDA-0054 for Z-390-100 and Z-390-101, respectively.
Confirmed with NDA personnel during inspection.
 Have background measurements been taken each operational day? Have any instances of problematic background radiation been documented?
                                       Y
Background measurements are taken between each assay. The EPA witnessed this during the inspection
 Have system performance checks been completed at least once per operational day? Are the procedures for the performance checks technically adequate for the Integrated Waste Assay System Z-390-100 and Z-390-101, including gamma matrix correction checks, and gamma peak position and resolution checks?
                                       Y
Performance measurements are taken daily, as confirmed in the electronic logbook. The procedures for the performance checks are technically adequate for the IWAS Z-390-100 and Z-390-101 units.
 System Calibration & Calibration Verifications
   
   
 Do the Integrated Waste Assay System Z-390-100 and Z-390-101 have a calibration of record? Were consensus standards used in the initial calibration? If so, which standards?
                                       Y
Both IWAS units were calibrated at the Canberra factory prior to their shipment to the AMWTP. Upon installation at the AMWTP, factory calibrations were verified as documented in SATR CI-IDA-NDA-0053 and CI-IDA-NDA-0054. Calibration activities for both IWAS units were done in accordance with CI-IDA-NDA-0031. AMWTP-RPT-TRUW-03, Revision 5, references consensus standards ASTM C1030, ASTM C1207 and ASTM C1316.
 Are the calibration, execution of performance checks and operation of the Integrated Waste Assay System Z-390-100 and Z-390-101, the calculation of radionuclide values and the review/validation of Integrated Waste Assay System Z-390-100 and Z-390-101 data governed by controlled-copy (formal) procedures?
                                       Y
Verification of the instruments' calibration has been performed many times, as documented on summary forms provided by the AMWTP, including routine maintenance and replacement of the gamma detector(s).
 Are the current revisions of procedures in use for the Integrated Waste Assay System Z-390-100 and Z-390-101?
                                       Y
These procedures are current, and copies of each were found and easily accessible in the IWAS control rooms for the Z-390-100 and Z-390-101 IWAS units.
 Are the isotopic contributions of unmeasured radionuclides derived using a certain method?
                                       Y
[241]Am and Pu isotopics are determined by FRAM software; site-approved AK is used for default isotopics. Confirmed with AMWTP NDA personnel during evaluation.
 Were traceable radionuclide sources used for calibration confirmation and/or verifications? 
                                       Y
Traceable standards were used, as verified by inspector.
 Have the operational ranges with respect to matrix (density) and activity been determined for the Integrated Waste Assay System Z-390-100 and Z-390-101? 
                                       Y
Operating ranges are specified in SATRs CI-IDA-NDA-0053 and CI-IDA-NDA-0054. The IWAS calibrations are not mass calibrations in a strict sense, although the operating range is expressed in 0.010 g - 200 g WG Pu. In theory, any assay within energy range for gamma or AAS range for PN that meets measurement criteria is acceptable.
Matrices used for AN and PN calibrations include combustibles, glass, organic and inorganic sludges (solids), and metals. For gamma mode, matrices with densities up to 1.6 g/cm[3] were used. Matrices for all operational modes are representative with respect to physical form and activity.
 Have calibration verifications been completed for the Integrated Waste Assay System Z-390-100 and Z-390-101? 
                                       Y
Calibration verifications are documented in work orders at the AMWTP; none have been performed since Fluor took over operations on the systems.
 Do the Integrated Waste Assay System Z-390-100 and Z-390-101 meet the requirements for accuracy and precision as specified in DOE/WIPP-02-3122, Appendix A, Table A-2 for calibration verifications?
                                       Y
The requirements for accuracy and precision specified in DOE/WIPP-02-3122, Appendix A, are met as specified in Site Acceptance Test Reports CI-IDA-NDA-0053 and CI-IDA-NDA-0054.
 Have any NCRs related to the Integrated Waste Assay System Z-390-100 or Z-390-101 been issued since the last EPA Continued Compliance inspection?
                                       Y
There have been no system NCRs on the Integrated Waste Assay System Z-390-100 and Z-390-101 since the last inspection. Confirmed during interviews with AMWTP personnel during inspection. A list of assay-specific NCRs was provided to the EPA.

 Describe the Retrieval Box Assay System. 
                                       Y
The RBAS is an imaging PN-AN measurement system supplemented by an HPGe gamma detection system. The passive and/or active neutron data are used in conjunction with gamma-based isotopic determinations using PC-FRAM to quantify specific radionuclides and/or determine an item's FGE. Isotopic information can also be provided by approved AK. Integration of the neutron and isotopic data for each item is performed off line by the RBAS WIPP Analysis Reporting Software for Expert Analysis (RWARS-EA).
 System Performance

 Describe the Waste Assay Gamma System. 
                                       
The WAGS is a standard Canberra IQ3 Assay System gamma system and consists of six high-resolution BEGe gamma detectors, a drum turntable, shielded enclosure, and supporting electronics. The six gamma detectors are arranged in two groups of three, the North bank and the West bank; the detectors in each group are aligned vertically (i.e., aligned to one central vertical axis). The North bank detectors (North top, North middle and North bottom) acquire spectra for quantitative analyses. Under the supplemental calibration, each of the North bank detectors is fitted with a removable filter made of 3 mm Pb, 3 mm Cd, and a thin layer of Cu with the Cu layer closest to the detector. These filters reduce dead time. The North bank detectors are positioned 180 degrees from a set of three [1][33]Ba sources that are used for matrix density corrections. Spectra are acquired simultaneously and represent the upper, middle and lower segments of the drum volume. Data may be individually transmission-corrected to compensate for density, or they may be summed and analyzed against a multi-curve efficiency when the density prohibits sufficient transmission of the [133]Ba photons. The West bank detectors (West top, West middle and West bottom) acquire spectra for isotopic analyses and are positioned 90 degrees relative to the North bank. Under the supplemental calibration, each of the West bank detectors has been fitted with a 32 mm Cd filter.

CCP-INL-SGRS-001, SWEPP Gamma-Ray Spectrometer (SGRS) Calibration, Confirmation and Verification Report, Revision 2, November 14, 2012.
 Have the operational ranges with respect to matrix (density) and activity been determined for the SWEPP Gamma-Ray Spectrometer? 
                                       Y
Range ~0.010 g to 200 g Total Pu (calibration-based and administrative). Limited by LLD and system dead-time. Calibration assumes that the matrices are mainly Z < 15, which includes debris, soil/gravel and solids. Waste matrices outside range and/or presence of denser materials (Z>15) require expert review.
 Has a calibration verification been completed for the SWEPP Gamma-Ray Spectrometer? If so, what is the date of the last calibration verification? Have any others been completed in the last year?
                                       Y
A calibration verification was completed following the replacement of detector 4. The AMWTP work order associated with this verification was provided to the EPA reviewers.
 Does the SWEPP Gamma-Ray Spectrometer meet the requirements for accuracy and precision as specified in DOE/WIPP-02-3122, Appendix A, Table A-2 for calibration verifications?
                                       Y
As documented in CCP-INL-SGRS-001, Revision 2, SWEPP Gamma-Ray Spectrometer (SGRS) Calibration, Confirmation, and Verification Report, Revision 2, dated November 14, 2012; and INST-TRUW-8.1.4, Waste Assay Gamma Spectrometer/SWEPP Gamma-Ray Spectrometer Post-Maintenance Calibration and Verification.
 Have any NCRs related to the SWEPP Gamma-Ray Spectrometer been issued since the last EPA Continued Compliance inspection?
                                       Y
A list of Type 1 NCRs was provided to the EPA during the inspection.
 Do the BDRs contain:
 Testing facility name, testing batch number, container numbers, and signature of the SPM or designee?
 Table of contents?
 Background and performance check data or control charts for the relevant time period?
 Separate testing report sheets for each container?
                                       Y
The EPA reviewed SGRS BDRs to confirm they contain all appropriate information.
 Do the RDSs include:
 Method/procedure used?
 Date of radioassay?
 Activities and associated TMU for individual radionuclides?
 TRU alpha concentration and its associated TMU?
 Operator and reviewer signatures?
                                       Y
The EPA reviewed SWEPP Gamma-Ray Spectrometer BDRs to confirm they contain RDSs with all appropriate information.
 Total Measurement Uncertainty
   
   
 Is the magnitude of the TMU values observed in the SWEPP Gamma-Ray Spectrometer BDRs examined during the inspection within the expected range?
                                       Y
The TMU for the SGRS is documented in CCP-INL-SGRS-002, Total Measurement Uncertainty for the SGRS Assay System, dated April 21, 2005.
 Lower Limit of Detection
   
   
 Has the LLD for the SWEPP Gamma-Ray Spectrometer has been determined? Is the LLD determination appropriate for the types of TRU waste the AMWTP expects to assay on the SWEPP Gamma-Ray Spectrometer? Is the technical basis for the LLD determination documented?
                                       Y
Reporting thresholds for [90]Sr and other radionuclides are determined and documented appropriately. 
 Is the SWEPP Gamma-Ray Spectrometer used to discriminate TRU/Non-TRU wastes at the 100 nCi/g criterion? If so, does the SWEPP Gamma-Ray Spectrometer have the required sensitivity? 
                                       Y
TRU discrimination is regularly done on the instrument, as evidenced by the large number of drums that fall out as non-TRU (typically these are LLW).
 Are there any instances where an LLD value for a non-measured radionuclide is not provided based on a lack of technical feasibility?
                                       Y
A reporting threshold for [234]U is not determined, based on the AMWTP's statement that it "is not technically feasible to determine a unique reporting threshold for [234]U," a technical position supported by DOE/WIPP-02-31224.
 PDP Participation
   

 Has the SWEPP Gamma-Ray Spectrometer participated successfully in the CBFO NDA PDP? If so, identify the last cycle.
                                       Y
The SGRS last successfully participated in the CBFO PDP drum Cycle 24A. Evidence of this was provided to EPA inspectors.
 Training

 Do all operators have current CCP training as verified on an LOQI?
                                       Y
All operators have current training as verified in the out-of-plant LOQI-equivalent document.
 Are SWEPP Gamma-Ray Spectrometer data reviewed and approved by qualified personnel? If so, identify the name of the individuals performing technical review and approval of SWEPP Gamma-Ray Spectrometer BDRs.
                                       Y
In the BDRs reviewed by the EPA, data review was performed by J. Law and B. Dial.

 Do AMWTP procedures provide complete instructions for operators to perform the CH RTR examination and complete associated documentation?
                                       Y
The EPA observed the RTR examination of the Z-213-106 and 1001 RTR units. The operator had performed the necessary equipment checks before the EPA's arrival. The EPA observed the entire RTR examination of the Z-213-106 and 1001 drums, including generation of the electronic and audiovisual records. Waste items were identified by the operator on the audiovisual recording and entered electronically into the RTR data sheet; the WMC was verified; and the container's fill height was determined. The operator used the appropriate AMWTP procedures to guide the examination and referenced the waste stream AK summary, as necessary. The RTR procedures for both units include detailed operational instructions and tables for waste item weights and prohibited items. Both operators were able to describe the NCR process and when NCRs are initiated. The EPA reviewed a list of qualified individuals and determined that the RTR operators for both units were properly qualified.
