Proposed Approval of the Central Characterization Project's 
Remote-Handled 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, remote-handled (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,

[[Page 11113]]

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 remote-
handled 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.
---------------------------------------------------------------------------

    \1\ A companion CH waste stream has the same summary category 
group, same waste stream 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.

---------------------------------------------------------------------------

[[Page 11114]]

    (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.

* SRS-CCP will report all T2 changes to EPA every three months.
** Substantive modification refers to a change with the potential to
  affect SRS-CCP's RH waste characterization process; e.g., the use of
  an inherently different type of measurement instrument or the use of
  probes not described in CCP-TP-504, excluding changes related solely
  to safety or to address administrative concerns.
*** Notification to EPA is not necessary when document updates are
  editorial in nature or are required solely to address administrative
  concerns.

IV. Availability of the Baseline Inspection Report for Public Comment

    EPA has placed the report discussing the results of the Agency's 
inspection of the SRS-CCP Site in the public docket as described in 
ADDRESSES. In accordance with 40 CFR 194.8, EPA is providing the public 
45 days to comment on these documents. The Agency requests comments on 
the proposed approval decision, as described in the inspection report. 
EPA will accept public comment on this notice and supplemental 
information as described in Section 1 above. The Agency will not make a 
determination of compliance before the 45-day comment period ends. At 
the end of the public 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, both of which will be posted on the WIPP Web site.
    Information on the certification decision is filed in the official 
EPA Air Docket, Docket No. A-93-02 and is available for review in 
Washington, DC, and at the three EPA WIPP informational docket 
locations in Albuquerque, Carlsbad, and Santa Fe, New Mexico. The 
dockets in New Mexico contain only major items from the official Air 
Docket in Washington, DC, plus those documents added to the official 
Air Docket since the October 1992 enactment of the WIPP LWA.
