ENVIRONMENTAL PROTECTION 

AGENCY 

[EPA–HQ–OAR–2012–0036; FRL–9636–4] 

Proposed Approval of the Central 

Characterization Project’s RemoteHandled Transuranic Waste 

Characterization Program at the 

Savannah River Site 

AGENCY: Environmental Protection 

Agency. 

ACTION: Notice of availability; opening 

of public comment period. 

SUMMARY: The Environmental Protection 

Agency (EPA) is announcing the 

availability of, and soliciting public 

comments for 45 days on, the proposed 

approval of the radioactive, remotehandled (RH), transuranic (TRU) waste 

characterization program implemented 

by the Central Characterization Project 

(CCP) at the Savannah River Site (SRS) 

in Aiken, South Carolina. This waste is 

intended for disposal at the Waste 

Isolation Pilot Plant (WIPP) in New 

Mexico. 

In accordance with the WIPP 

Compliance Criteria, EPA evaluated the 

characterization of RH TRU debris waste 

from SRS–CCP during an inspection on 

August 30–September 1, 2011, with a 

follow-up inspection on December 6–7, 

2011, at SRS. Using the systems and 

processes developed as part of the U.S. 

Department of Energy’s (DOE’s) 

Carlsbad Field Office (CBFO) program, 

EPA verified whether DOE could 

adequately characterize RH TRU waste 

consistent with the Compliance Criteria. 

The results of EPA’s evaluation of SRS– 

CCP’s RH program and its proposed 

approval are described in the Agency’s 

inspection report, which is available for 

review in the public dockets listed in 

ADDRESSES. EPA will consider public 

comments received on or before the due 

date mentioned in DATES. 

This notice summarizes the waste 

characterization processes evaluated by 

EPA and EPA’s proposed approval. As 

required by the 40 CFR 194.8, at the end 

of a 45-day comment period EPA will 

evaluate all relevant public comments 

and revise the inspection report as 

necessary. If appropriate, the Agency 

will then issue a final approval letter 

and inspection report. 

DATES: Comments must be received on 

or before April 9, 2012.

II. Background 

DOE is developing the WIPP, near 

Carlsbad in southeastern New Mexico, 


srobinson on DSK4SPTVN1PROD with NOTICES
Federal Register / Vol. 77, No. 37 / Friday, February 24, 2012 / Notices 11113 

1A companion CH waste stream has the same 

summary category group, same waste stream 

Continued 

as a deep geologic repository for 

disposal of TRU radioactive waste. As 

defined by the WIPP Land Withdrawal 

Act (LWA) of 1992 (Pub. L. 102–579), as 

amended (Pub. L. 104–201), TRU waste 

consists of materials that have atomic 

numbers greater than 92 (with half-lives 

greater than twenty years), in 

concentrations greater than 100 

nanocuries of alpha-emitting TRU 

isotopes per gram of waste. Much of the 

existing TRU waste consists of items 

contaminated during the production of 

nuclear weapons, such as rags, 

equipment, tools, and sludges. 

TRU waste is itself divided into two 

categories, based on its level of 

radioactivity. Contact-handled (CH) 

TRU waste accounts for about 97 

percent of the volume of TRU waste 

currently destined for the WIPP. It is 

packaged in 55-gallon metal drums or in 

metal boxes and can be handled under 

controlled conditions without any 

shielding beyond the container itself. 

The maximum radiation dose at the 

surface of a CH TRU waste container is 

200 millirems per hour. CH waste 

primarily emits alpha particles that are 

easily shielded by a sheet of paper or 

the outer layer of a person’s skin. 

Remote-handled (RH) TRU waste 

emits more radiation than CH TRU 

waste and must therefore be both 

handled and transported in shielded 

casks. Surface radiation levels of 

unshielded containers of remotehandled transuranic waste exceed 200 

millirems per hour. RH waste primarily 

emits gamma radiation, which is very 

penetrating and requires concrete, lead 

or steel to block it. 

On May 13, 1998, EPA issued a final 

certification of compliance for the WIPP 

facility. The final rule was published in 

the Federal Register on May 18, 1998 

(63 FR 27354). The Agency officially 

recertified WIPP on November 18, 2010 

(75 FR 70584). Both the certification and 

recertification determined that WIPP 

complies with the Agency’s radioactive 

waste disposal regulations at 40 CFR 

part 191, subparts B and C, and is 

therefore safe to contain TRU waste. 

The final WIPP certification decision 

includes conditions that (1) prohibit 

shipment of TRU waste for disposal at 

WIPP from any site other than Los 

Alamos National Laboratories (LANL) 

until EPA determines that the site has 

established and executed a quality 

assurance program, in accordance with 

194.22(a)(2)(i), 194.24(c)(3) and 

194.24(c)(5) for waste characterization 

activities and assumptions (Condition 2 

of Appendix A to 40 CFR part 194); and 

(2) (with the exception of specific, 

limited waste streams and equipment at 

LANL) prohibit shipment of TRU waste 

for disposal at WIPP (from LANL or any 

other site) until EPA has approved the 

procedures developed to comply with 

the waste characterization requirements 

of 194.22(c)(4) (Condition 3 of 

Appendix A to 40 CFR part 194). The 

Agency’s approval process for waste 

generator sites is described in 194.8 

(revised July 2004). 

Condition 3 of the WIPP Certification 

Decision requires EPA to conduct 

independent inspections at DOE’s waste 

generator/storage sites of their TRU 

waste characterization capabilities 

before approving their program and the 

waste for disposal at the WIPP. The 

Agency’s inspection and approval 

process gives EPA (a) discretion in 

establishing technical priorities, (b) the 

ability to accommodate variation in the 

site’s waste characterization 

capabilities, and (c) flexibility in 

scheduling site waste characterization 

inspections. 

As described in Section 194.8(b), 

EPA’s baseline inspections evaluate 

each waste characterization process 

component (equipment, procedures and 

personnel training/experience) for its 

adequacy and appropriateness in 

characterizing TRU waste destined for 

disposal at WIPP. During an inspection, 

the site demonstrates its capabilities to 

characterize TRU waste(s) and its ability 

to comply with the regulatory limits and 

tracking requirements under 194.24. A 

baseline inspection may describe any 

limitations on approved waste streams 

or waste characterization processes 

[194.8(b)(2)(iii)]. In addition, a baseline 

inspection approval must specify what 

subsequent waste characterization 

program changes or expansion should 

be reported to EPA [194.8(b)(4)]. The 

Agency is required to assign a Tier 1 

(T1) or Tier 2 (T2) designation to the 

reportable changes depending on their 

potential impact on data quality. A T1 

designation requires that the site notify 

EPA of proposed changes to the 

approved components of an individual 

waste characterization process (such as 

radioassay equipment or personnel), 

and that EPA approve the change before 

it is implemented. A waste 

characterization element with a T2 

designation allows the site to implement 

changes to the approved components of 

individual waste characterization 

processes (such as visual examination 

procedures) but requires EPA 

notification. The Agency may choose to 

inspect the site to evaluate technical 

adequacy before approval. EPA 

inspections conducted to evaluate T1 or 

T2 changes are follow-up inspections 

under the authority of 194.24(h). In 

addition to the follow-up inspections, 

EPA may opt to conduct continued 

compliance inspections at TRU waste 

sites with a baseline approval under the 

authority of 194.24(h). 

The site inspection and approval 

process outlined in 194.8 requires EPA 

to issue a Federal Register notice 

proposing the baseline compliance 

decision, docket the inspection report 

for public review, and seek public 

comment on the proposed decision for 

a period of 45 days. The report must 

describe the waste characterization 

processes EPA inspected at the site, as 

well as their compliance with 194.24 

requirements. 

III. Proposed Baseline Compliance 

Decision 

EPA has performed a baseline 

inspection of RH TRU waste 

characterization activities at SRS–CCP 

(EPA Inspection No. EPA–SRS–CCP– 

RH–08.11–8). The purpose of EPA’s 

inspection was to verify that the waste 

characterization program implemented 

at SRS–CCP for characterizing RH TRU, 

retrievably-stored, debris waste is 

technically adequate and meets the 

regulatory requirements at 40 CFR 

194.24. 

The inspection took place from 

August 30–September 1, 2011, with a 

follow-up inspection on December 6–7, 

2011, at SRS. The Agency’s inspection 

team evaluated: The use of acceptable 

knowledge (AK); dose-to-curie (DTC) in 

conjunction with radionuclide-specific 

scaling factors derived in part by 

measurement with the In Situ Object 

Counting System (ISOCS) and historical 

assays of containers from the CH 

counterpart waste stream at SRS 

(SRW027–FB–Pre-86–C); and real-time 

radiography (RTR) to confirm the 

physical form and waste material 

parameters (WMP) of waste drums. 

The inspection’s scope included one 

RH TRU waste stream, SR–RH–FBL.01, 

consisting of debris waste from the FB– 

Line at SRS. This waste was generated 

by glovebox operations, 

decontamination, housekeeping, 

maintenance and construction activities 

conducted from 1975 through 1984. 

EPA proposes to approve the SRS–CCP 

waste characterization program 

implemented to characterize RH debris 

waste from Waste Stream SR–RH– 

FBL.01 that was evaluated during this 

baseline inspection and is documented 

in this report. The proposed approval 

includes the following: 

(1) The AK process for RH TRU debris 

waste streams that have companion 1 CH 

debris waste streams. 


srobinson on DSK4SPTVN1PROD with NOTICES
11114 Federal Register / Vol. 77, No. 37 / Friday, February 24, 2012 / Notices 

definition, and same radiological and physical 

properties as the subject RH waste stream. In this 

case, the only difference between containers in the 

companion CH waste stream and those in the 

subject RH waste stream is the waste’s external dose 

rate; i.e., less than or greater than 200 millirem per 

hour (mrem/hr), which makes the waste CH or RH, 

respectively. 

(2) The radiological characterization 

of eight drums in Waste Stream SR–RH– 

FBL.01 using the ORTEC/ISOCS prior to 

the baseline inspection and historical 

assays of companion CH debris waste 

streams for assigning radionuclide 

values, according to the limitations 

discussed in Section 8.2 of the 

inspection report. 

(3) The radiological characterization 

process using DTC and scaling factors 

generated through use of the Mobile 

Characterization Services (MCS)/ISOCS 

and historical assays of companion CH 

debris waste streams for assigning 

radionuclide values for RH waste, as 

documented in CCP–AK–SRS–581, 

Revision 1, supported by the calculation 

packages (or equivalent documentation), 

and subject to the limitations discussed 

in Section 8.2 of this report. 

(4) The RTR process to identify WMPs 

and the physical form of RH TRU debris 

waste. 

Once this approval is final, SRS– 

CCP’s RH TRU waste characterization 

program will be able to characterize RH 

waste from Waste Stream SR–RH– 

FBL.01 in accordance with the 

conditions and restrictions discussed in 

the accompanying inspection report and 

summarized in Table 1 below. After 

EPA finalizes the SRS–CCP RH waste 

characterization program approval, 

additional debris waste stream(s) having 

a companion CH waste stream(s) may be 

disposed of at WIPP provided that an 

approved radiological scaling factor 

development process is used. 

Further, the MCS/ISOCS use is 

limited to the generation of specific 

radionuclide ratios (scaling factors), i.e., 

the activity of plutonium (Pu) isotopes 

plutonium-239 (239Pu), plutonium-240 

(240Pu) and plutonium-241 (241Pu) to 

americium-241 (241Am). Its use for 

direct quantification of any 

radionuclides including plutonium-238 

is prohibited. 

A Tier 1 change approval is necessary 

when: 

• The radiological scaling factors 

development process used for 

characterizing RH debris waste differs 

from the process approved; 

• An RH TRU debris waste stream 

characterized for WIPP disposal does 

not have a companion CH waste stream; 

• An RH TRU non-debris waste 

stream from a summary category group 

solids (S3000) or soils and gravel 

(S4000) is characterized for WIPP 

disposal; and 

• Using the ORTEC/ISOCS for RH 

debris waste characterization in the 

future. 

Table 1 below (which is outlined in 

the inspection report) identifies the 

proposed tiering changes based on the 

baseline inspection elements.
