ACTION: Notice of availability; opening of public comment period. cprice-sewell on PRODPC62 with NOTICES AGENCY: SUMMARY: The Environmental Protection Agency (EPA or we) is announcing the availability of, and soliciting public comments for 45 days on, the proposed approvals of the radioactive, remotehandled (RH), transuranic (TRU) waste characterization programs implemented by the Central Characterization Project (CCP) at Idaho National Laboratory (INL) and Argonne National Laboratory (ANL). This waste is intended for disposal at the Waste Isolation Pilot Plant (WIPP) in New Mexico. These are the first proposed approvals for the characterization of RH waste. In accordance with the WIPP Compliance Criteria, EPA evaluated the characterization of RH TRU debris waste from INL–CCP and ANL–CCP during inspections conducted the weeks of June 12, 2006, and September 11, 2006, respectively. Using the systems and processes developed as part of the U.S. Department of Energy’s (DOE’s) Carlsbad Field Office (CBFO) program to characterize RH TRU waste, EPA verified whether DOE could adequately characterize RH TRU waste consistent with the Compliance Criteria. The results of EPA’s evaluations of the INL– CCP and ANL–CCP programs and their proposed approvals are described in the Agency’s inspection reports, which are VerDate Aug<31>2005 16:09 Nov 07, 2006 Jkt 211001 available for review in the public dockets listed in ADDRESSES. We 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 approvals.

II. Background DOE is developing the WIPP, near Carlsbad in southeastern New Mexico, 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 PO 00000 Frm 00039 Fmt 4703 Sfmt 4703 65489 emits gamma radiation, which is very penetrating and requires concrete, lead, or steel to block it. On May 13, 1998, EPA announced its final compliance certification decision to the Secretary of Energy (published May 18, 1998, 63 FR 27354). This decision stated that the WIPP will comply with EPA’s radioactive waste disposal regulations at 40 CFR Part 191, Subparts B and C. The final WIPP certification decision includes conditions that (1) Prohibit shipment of TRU waste for disposal at WIPP from any site other than the Los Alamos National Laboratories (LANL) until the 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 EPA’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. EPA’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 WC inspections. As described in Section 194.8(b), EPA’s baseline inspections evaluate each WC 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 WC program changes or expansion should be reported to EPA [§ 194.8(b)(4)]. The E:\FR\FM\08NON1.SGM 08NON1 65490 Federal Register / Vol. 71, No. 216 / Wednesday, November 8, 2006 / Notices cprice-sewell on PRODPC62 with NOTICES Agency is required to assign Tier 1 (T1) and Tier 2 (T2) to the reportable changes depending on their potential impact on data quality. A T1 designation requires that the site must notify EPA of proposed changes to the approved components of an individual WC process (such as radioassay equipment or personnel), and EPA must also approve the change before it can be implemented. A WC element with a T2 designation allows the site to implement changes to the approved components of individual WC 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, if warranted, 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 WC processes EPA inspected at the site, as well as their compliance with § 194.24 requirements. All waste characterization site approvals for WIPP, up until this point, have been applicable only to contacthandled (CH) TRU waste. The aforementioned inspections at INL–CCP and ANL–CCP mark the first two inspections related to RH waste. EPA previously issued a preliminary approval of DOE’s general framework for characterizing RH waste on March 26, 2004 (Docket A–98–49, Item II–B2– VerDate Aug<31>2005 15:11 Nov 07, 2006 Jkt 211001 21). This approval requires DOE to provide site-specific RH waste characterization plans and characterization procedures for EPA approval prior to implementing them for characterizing RH waste. III. Proposed Baseline Compliance Decisions EPA has performed baseline inspections of RH TRU waste characterization activities of INL–CCP (EPA Inspection No. EPA–INL–CCP– RH–06–06–8) and ANL–CCP (EPA Inspection No. EPA–ANL–CCP–RH–09– 06–8). The purpose of EPA’s inspections were to verify that the RH waste characterization programs implemented at both INL–CCP and ANL–CCP for characterizing RH TRU, retrievablystored, debris waste (S5000) are adequate. EPA evaluated whether the RH waste characterized meets the regulatory requirements at 40 CFR 194.24. During these inspections, EPA evaluated the adequacy, implementation, and effectiveness of the waste characterization activities at INL– CCP and ANL–CCP. The Agency’s evaluation focused on the individual components—equipment, procedures, and personnel training/experience of the following waste characterization processes: acceptable knowledge (AK), radiological characterization using a dose-to-curie (DTC) procedure, visual examination (VE), and load management. The RH waste characterization programs at INL–CCP and ANL–CCP are based on DOEprovided upper-tier documents. A. June 2006 INL–CCP RH Inspection Results At INL, EPA’s inspection team identified one finding in the area of VE and six concerns that needed to be addressed by DOE. Two of these PO 00000 Frm 00040 Fmt 4703 Sfmt 4703 concerns were in VE and four in AK. DOE responded to the EPA finding and concerns and the Agency determined the DOE responses were satisfactory. EPA’s inspection team determined that INL–CCP’s RH WC program activities were technically adequate. (For complete discussion of EPA’s findings, concerns, and technical evaluation, see EPA INL CCP RH Inspection Report A– 98–42, II–A4–69 in the accompanying EPA Docket.) EPA is proposing to approve CCP’s AK, DTC, and VE processes implemented at INL in the configuration observed during a June 2006 inspection and during two subsequent follow-up inspections (July & August), and as described in the inspection report A–98–42, II–A4–69. The proposed approval includes the following: (1) The AK process for RH retrievablystored TRU debris in one waste stream, Idaho National Laboratory Waste Stream No. ID–ANLE–S5000, Lots 1 through 20, as defined in CCP–AK–INL–500, Revision 2, June 1, 2006. (2) The radiological characterization process using dose-to-curie (DTC) and modeling-derived scaling factors for assigning radionuclide values to one RH waste stream for which the scaling factors are applicable, as described in CCP–AK–INL–501, Revision 1. (3) The VE process used for a total of 8 retrievably-stored RH debris waste drums included in three batch data reports—BDR No.’s RHINLVE 6001–03. CCP has terminated the use of VE process for this waste until further notice. If CCP decides to use VE in the future EPA inspection and approval is necessary. Any changes to the WC activities from the date of the baseline inspection must be reported to and, if applicable, approved by EPA, according to Table 1 below.

All T1 changes must be submitted for approval before their implementation and will be evaluated by EPA. Upon approval, EPA will post the results of the evaluations through the WIPP Web site and the WIPP–NEWS list, as described above. EPA will post T2 changes approximately every three months beginning with the date of EPA’s approval of the TRU WC program implemented at INL–CCP. EPA expects the first report of INL–CCP’s T2 changes approximately three months from date of EPA’s approval of the TRU WC program implemented at INL–CCP. In this notice, EPA is not proposing to approve WIPP Waste Information VerDate Aug<31>2005 15:11 Nov 07, 2006 Jkt 211001 System (WWIS) for tracking of waste contents of RH debris wastes. Although the WWIS is currently approved by EPA for tracking CH waste, this system has not been demonstrated by DOE for the Agency for tracking RH waste. Therefore, in accordance with 194.8(b)(2)(iii), EPA is placing a limitation on this proposed baseline that requires DOE to provide WWIS information as a T1 change. EPA will review the WWIS database populated with actual RH waste content data when the RH modules have been completed. EPA may conduct the evaluation of the WWIS during this comment period; however, no final decision or approval of the WWIS will be made until a baseline approval is finalized. No RH waste can be shipped to WIPP for disposal until EPA approves the WWIS PO 00000 Frm 00041 Fmt 4703 Sfmt 4703 database through the T1 process. Similarly, if INL–CCP intends to use an RTR unit to evaluate RH drum contents, EPA will also evaluate this process as a T1 change. Although EPA may evaluate INL–CCP’s RTR prior to a baseline approval, no decision or approval regarding RTR will be made until a baseline approval is finalized. B. September 2006 ANL–CCP RH Inspection Results At ANL, EPA’s inspection team identified three concerns; two in VE and one in AK. DOE responded to the EPA concerns and the Agency determined that the DOE responses were satisfactory. EPA’s inspection team determined that ANL–CCP’s RH WC program activities were technically adequate. (For a complete discussion of E:\FR\FM\08NON1.SGM 08NON1 65492 Federal Register / Vol. 71, No. 216 / Wednesday, November 8, 2006 / Notices EPA’s findings, concerns, and technical evaluation, see EPA ANL CCP RH Inspection Report A–98–42, II–A4–70 in the accompanying EPA Docket.) EPA is proposing to approve CCP’s AK, DTC, and VE processes implemented at ANL in the configuration observed during the September 2006 inspection and as described in the inspection report A– 98–49, II–A4–70. The proposed approval includes the following: (1) The AK process for RH retrievablystored TRU debris in one waste stream, Waste Stream AERHDM, as defined in CCP–AK–ANLE–501, Revision 0, July 21, 2006. (2) The radiological characterization process using DTC and modelingderived scaling factors for assigning radionuclide values to one RH waste stream for which the scaling factors are applicable, as described in CCP–AK– ANL–501, Revision 1.

Proposed Approvals of the Central Characterization Project's 
Remote-Handled Waste Characterization Programs at Idaho National 
Laboratory and Argonne National Laboratory

AGENCY: Environmental Protection Agency.

ACTION: Notice of availability; opening of public comment period.

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

SUMMARY: The Environmental Protection Agency (EPA or we) is announcing 
the availability of, and soliciting public comments for 45 days on, the 
proposed approvals of the radioactive, remote-handled (RH), transuranic 
(TRU) waste characterization programs implemented by the Central 
Characterization Project (CCP) at Idaho National Laboratory (INL) and 
Argonne National Laboratory (ANL). This waste is intended for disposal 
at the Waste Isolation Pilot Plant (WIPP) in New Mexico. These are the 
first proposed approvals for the characterization of RH waste.
    In accordance with the WIPP Compliance Criteria, EPA evaluated the 
characterization of RH TRU debris waste from INL-CCP and ANL-CCP during 
inspections conducted the weeks of June 12, 2006, and September 11, 
2006, respectively. Using the systems and processes developed as part 
of the U.S. Department of Energy's (DOE's) Carlsbad Field Office (CBFO) 
program to characterize RH TRU waste, EPA verified whether DOE could 
adequately characterize RH TRU waste consistent with the Compliance 
Criteria. The results of EPA's evaluations of the INL-CCP and ANL-CCP 
programs and their proposed approvals are described in the Agency's 
inspection reports, which are available for review in the public 
dockets listed in ADDRESSES. We 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 approvals. As required by the 40 
CFR 194.8, at the end of a 45-day comment period EPA will evaluate 
public comments received, and if appropriate, finalize the reports 
responding to the relevant public comments, and issue final reports and 
approval letters to DOE.

DATES: Comments must be received on or before December 26, 2006.

II. Background

    DOE is developing the WIPP, near Carlsbad in southeastern New 
Mexico, 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 announced its final compliance certification 
decision to the Secretary of Energy (published May 18, 1998, 63 FR 
27354). This decision stated that the WIPP will comply with EPA's 
radioactive waste disposal regulations at 40 CFR Part 191, Subparts B 
and C.
    The final WIPP certification decision includes conditions that (1) 
Prohibit shipment of TRU waste for disposal at WIPP from any site other 
than the Los Alamos National Laboratories (LANL) until the EPA 
determines that the site has established and executed a quality 
assurance program, in accordance with Sec.  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 Sec.  
194.22(c)(4) (Condition 3 of Appendix A to 40 CFR Part 194). The EPA's 
approval process for waste generator sites is described in Sec.  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. EPA'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 WC inspections.
    As described in Section 194.8(b), EPA's baseline inspections 
evaluate each WC 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 Sec.  194.24. A baseline inspection may 
describe any limitations on approved waste streams or waste 
characterization processes [Sec.  194.8(b)(2)(iii)]. In addition, a 
baseline inspection approval must specify what subsequent WC program 
changes or expansion should be reported to EPA [Sec.  194.8(b)(4)]. The

[[Page 65490]]

Agency is required to assign Tier 1 (T1) and Tier 2 (T2) to the 
reportable changes depending on their potential impact on data quality. 
A T1 designation requires that the site must notify EPA of proposed 
changes to the approved components of an individual WC process (such as 
radioassay equipment or personnel), and EPA must also approve the 
change before it can be implemented. A WC element with a T2 designation 
allows the site to implement changes to the approved components of 
individual WC 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 Sec.  194.24(h). In addition to the follow-up inspections, 
if warranted, EPA may opt to conduct continued compliance inspections 
at TRU waste sites with a baseline approval under the authority of 
Sec.  194.24(h).
    The site inspection and approval process outlined in Sec.  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 WC processes EPA inspected at the 
site, as well as their compliance with Sec.  194.24 requirements.
    All waste characterization site approvals for WIPP, up until this 
point, have been applicable only to contact-handled (CH) TRU waste. The 
aforementioned inspections at INL-CCP and ANL-CCP mark the first two 
inspections related to RH waste.
    EPA previously issued a preliminary approval of DOE's general 
framework for characterizing RH waste on March 26, 2004 (Docket A-98-
49, Item II-B2-21). This approval requires DOE to provide site-specific 
RH waste characterization plans and characterization procedures for EPA 
approval prior to implementing them for characterizing RH waste.

III. Proposed Baseline Compliance Decisions

    EPA has performed baseline inspections of RH TRU waste 
characterization activities of INL-CCP (EPA Inspection No. EPA-INL-CCP-
RH-06-06-8) and ANL-CCP (EPA Inspection No. EPA-ANL-CCP-RH-09-06-8).
    The purpose of EPA's inspections were to verify that the RH waste 
characterization programs implemented at both INL-CCP and ANL-CCP for 
characterizing RH TRU, retrievably-stored, debris waste (S5000) are 
adequate. EPA evaluated whether the RH waste characterized meets the 
regulatory requirements at 40 CFR 194.24. During these inspections, EPA 
evaluated the adequacy, implementation, and effectiveness of the waste 
characterization activities at INL-CCP and ANL-CCP. The Agency's 
evaluation focused on the individual components--equipment, procedures, 
and personnel training/experience of the following waste 
characterization processes: acceptable knowledge (AK), radiological 
characterization using a dose-to-curie (DTC) procedure, visual 
examination (VE), and load management. The RH waste characterization 
programs at INL-CCP and ANL-CCP are based on DOE-provided upper-tier 
documents.

A. June 2006 INL-CCP RH Inspection Results

    At INL, EPA's inspection team identified one finding in the area of 
VE and six concerns that needed to be addressed by DOE. Two of these 
concerns were in VE and four in AK. DOE responded to the EPA finding 
and concerns and the Agency determined the DOE responses were 
satisfactory. EPA's inspection team determined that INL-CCP's RH WC 
program activities were technically adequate. (For complete discussion 
of EPA's findings, concerns, and technical evaluation, see EPA INL CCP 
RH Inspection Report A-98-42, II-A4-69 in the accompanying EPA Docket.) 
EPA is proposing to approve CCP's AK, DTC, and VE processes implemented 
at INL in the configuration observed during a June 2006 inspection and 
during two subsequent follow-up inspections (July & August), and as 
described in the inspection report A-98-42, II-A4-69. The proposed 
approval includes the following:
    (1) The AK process for RH retrievably-stored TRU debris in one 
waste stream, Idaho National Laboratory Waste Stream No. ID-ANLE-S5000, 
Lots 1 through 20, as defined in CCP-AK-INL-500, Revision 2, June 1, 
2006.
    (2) The radiological characterization process using dose-to-curie 
(DTC) and modeling-derived scaling factors for assigning radionuclide 
values to one RH waste stream for which the scaling factors are 
applicable, as described in CCP-AK-INL-501, Revision 1.
    (3) The VE process used for a total of 8 retrievably-stored RH 
debris waste drums included in three batch data reports--BDR No.'s 
RHINLVE 6001-03. CCP has terminated the use of VE process for this 
waste until further notice. If CCP decides to use VE in the future EPA 
inspection and approval is necessary.
    Any changes to the WC activities from the date of the baseline 
inspection must be reported to and, if applicable, approved by EPA, 
according to Table 1 below.

\***\ Substantive modification refers to a change with the potential to affect INL's RH WC process, e.g., the
  use of an inherently different type of measurement instrument or the use of the high range probe as described
  in CCP-TP-504.

    EPA will notify the public of the results of its evaluations of 
proposed T1 and T2 changes through the WIPP Web site and by forwarding 
e-mails to the WIPP-NEWS list. All T1 changes must be submitted for 
approval before their implementation and will be evaluated by EPA. Upon 
approval, EPA will post the results of the evaluations through the WIPP 
Web site and the WIPP-NEWS list, as described above. EPA will post T2 
changes approximately every three months beginning with the date of 
EPA's approval of the TRU WC program implemented at INL-CCP. EPA 
expects the first report of INL-CCP's T2 changes approximately three 
months from date of EPA's approval of the TRU WC program implemented at 
INL-CCP.
    In this notice, EPA is not proposing to approve WIPP Waste 
Information System (WWIS) for tracking of waste contents of RH debris 
wastes. Although the WWIS is currently approved by EPA for tracking CH 
waste, this system has not been demonstrated by DOE for the Agency for 
tracking RH waste. Therefore, in accordance with 194.8(b)(2)(iii), EPA 
is placing a limitation on this proposed baseline that requires DOE to 
provide WWIS information as a T1 change. EPA will review the WWIS 
database populated with actual RH waste content data when the RH 
modules have been completed. EPA may conduct the evaluation of the WWIS 
during this comment period; however, no final decision or approval of 
the WWIS will be made until a baseline approval is finalized. No RH 
waste can be shipped to WIPP for disposal until EPA approves the WWIS 
database through the T1 process. Similarly, if INL-CCP intends to use 
an RTR unit to evaluate RH drum contents, EPA will also evaluate this 
process as a T1 change. Although EPA may evaluate INL-CCP's RTR prior 
to a baseline approval, no decision or approval regarding RTR will be 
made until a baseline approval is finalized.

B. September 2006 ANL-CCP RH Inspection Results

    At ANL, EPA's inspection team identified three concerns; two in VE 
and one in AK. DOE responded to the EPA concerns and the Agency 
determined that the DOE responses were satisfactory. EPA's inspection 
team determined that ANL-CCP's RH WC program activities were 
technically adequate. (For a complete discussion of

[[Page 65492]]

EPA's findings, concerns, and technical evaluation, see EPA ANL CCP RH 
Inspection Report A-98-42, II-A4-70 in the accompanying EPA Docket.) 
EPA is proposing to approve CCP's AK, DTC, and VE processes implemented 
at ANL in the configuration observed during the September 2006 
inspection and as described in the inspection report A-98-49, II-A4-70. 
The proposed approval includes the following:
    (1) The AK process for RH retrievably-stored TRU debris in one 
waste stream, Waste Stream AERHDM, as defined in CCP-AK-ANLE-501, 
Revision 0, July 21, 2006.
    (2) The radiological characterization process using DTC and 
modeling-derived scaling factors for assigning radionuclide values to 
one RH waste stream for which the scaling factors are applicable, as 
described in CCP-AK-ANL-501, Revision 1.
    (3) The VE process for retrievably-stored RH debris waste.
    Any changes to the WC activities from the date of the baseline 
inspection must be reported to and, if applicable, approved by EPA, 
according to Table 2 (as seen below).

    In this notice, EPA is not proposing to approve WIPP Waste 
Information System (WWIS) for tracking of waste contents of RH debris 
wastes. Although the WWIS is currently approved by EPA for CH waste, 
the system has not yet been demonstrated by DOE for the Agency for 
tracking RH waste. Therefore, in accordance with 194.8(b)(2)(iii), EPA 
is placing a limitation on this proposed baseline that requires DOE to 
provide WWIS information as a T1 change. EPA will review the WWIS 
database populated with actual RH waste content data when the RH 
modules have been completed. EPA may conduct the evaluation of the WWIS 
during this comment period; however, no final decision or approval of 
the WWIS will be made until a baseline approval is finalized. No RH 
waste can be shipped to WIPP for disposal until EPA approves the WWIS 
database through the T1 process. In the future, if ANL-CCP intends to 
use an RTR unit to evaluate RH drum contents, EPA will evaluate this 
process as a T1 change.

IV. Availability of the Baseline Inspection Report for Public Comment

    EPA has placed both reports discussing the results of EPA's 
inspections of INL-CCP and ANL-CCP 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 decisions and tiering designations, as described 
in EPA's inspection reports. EPA will accept public comment on this 
notice and supplemental information as described in Section 1.B. above. 
EPA 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 reports 
as necessary. If appropriate, the Agency will then issue approval 
letters and final inspection reports, both of which will be posted on 
the WIPP Web site. DOE must obtain EPA approval of the WWIS, through 
the T1 change system prior to the disposal of RH waste at WIPP.
    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 New Mexico (as listed in ADDRESSES). The dockets in New
