physical properties for the high-level waste stored in the Hanford Tank Farms.’’

DOE intends to conduct large-scale testing with simulants selected to represent the vast majority of the waste in the tank farms, consistent with the approach used in WTP’s pulse jet mixing test program conducted to date. The WTP design and planned operations approach is intended to address residual uncertainty with other actions and design features. These include (1) waste feed pre-qualification activities; and (2) specific design features, including the ability to inspect vessels and equipment for vessel heel dilution and cleanout, that would enable waste particles that may not be mixing with
the bulk of the waste to be moved forward
to the melters.

• Sub-recommendation 3: This subrecommendation calls for ‘‘ * * * verification and validation of any computational models used by the WTP project team (e.g., Low Order Accumulation Model and FLUENT) based on the results from the ‘large-scale testing.’ ’’

The verification and validation effort is expected to be completed prior to the ‘‘large scale testing. ’’ The WTP project intends to compare the results from the ‘‘large scale testing’’ with the computational models.

• Sub-recommendation 4: This subrecommendation calls for ‘‘ * * * including demonstrating that representative samples can be obtained even if the assumed WTP design particle size or density is exceeded. This will ensure that the sampling system does not exclude large, dense particles and artificially bias the measured particle size and density distribution.’’

The vessel testing activities will include determining the acceptability of vessel sampling in conditions where sampling may be challenged by mixing performance, i.e., solids-containing vessels. There may be cases where the sample system operation during normal vessel operations does not retrieve some large dense particles for analysis. As noted above, this is planned to be accommodated by the feed-prequalification process and by the ability to pull a sample during the heel dilution and cleanout process, when larger, denser particles would be retrieved into the sample system. Consequently, the large-scale testing program is not intending to demonstrate that normal sampling activities can retrieve all waste particles.

DOE is committed to the safe design and operation of its nuclear facilities, consistent with the principles of Integrated Safety Management, and values input on how DOE can improve its activities. We look forward to working further with the Board and its staff on preparation of the DOE’s Implementation Plan for Recommendation 2010–2 so that the WTP project can complete its design and construction activities while promoting nuclear safety for the life of WTP operations.

**Proposed Agency Information Collection** 

**AGENCY :**  Office of Energy Efficiency and Renewable Energy, Department of Energy.

**ACTION :**  Notice and Request for
Comments.

**SUMMARY :**  The Department of Energy (DOE) invites public comment on a proposed collection of information to support the Weatherization Assistance Program ARRA–Period Evaluation that DOE is developing for submission to the Office of Management and Budget (OMB) pursuant to the Paperwork Reduction Act of 1995. Comments submitted in response to this notice will be summarized and/or included in the request for OMB approval of this information collection; they also will become a matter of public record. Information about the operation of the program, energy used before and after weatherization, energy used by control group low-income homes, the effectiveness of specific energy efficiency measures, customersatisfaction with the program, and nonenergy benefits is needed for a comprehensive and rigorous evaluation of the program operated during the American Recovery and Reinvestment Act of 2009 (ARRA), which includes Program Years 2009, 2010, and 2011.

**DATES :**  Comments regarding this proposed information collection must be received on or before May 10, 2011. If you anticipate difficulty in submitting comments within that period, contact the person listed in **ADDRESSES** as soon as possible.

**ADDRESSES :**  Written comments may be sent to: Bruce Tonn, Environmental Sciences Division, Oak Ridge National Laboratory, One Bethel Valley Road, P.O. Box 2008, MS–6038, Oak Ridge, TN 37831–6038, Fax #: (865) 576–8646, tonnbe@ornl.gov.

**FOR FURTHER INFORMATION CONTACT :**  Requests for additional information or copies of the information collection instrument and instructions should be directed to Bruce Tonn, Environmental Sciences Division, Oak Ridge National Laboratory, One Bethel Valley Road, P.O. Box 2008, MS–6038, Oak Ridge, TN 37831–6038, Fax #: (865) 576–8646, tonnbe@ornl.gov.

The plan for this evaluation can be found at http://weatherization.ornl.gov. The surveys and data forms that comprise this information request can also be found at http:// weatherization.ornl.gov.

**SUPPLEMENTARY INFORMATION :**  This package contains: (1) OMB No.: 1910– NEW; (2) Package Title: The Weatherization Assistance Program ARRA–Period Evaluation; (3) Type of
Review: Regular; (4) Purpose: This collection of information is necessary for a complete evaluation of the program that will weatherize approximately 600,000 low-income homes in Program Years 2009, 2010 and 2011; (5) Estimated Number of Total Respondents: 6,996. Information will be collected from seventy-four grantees (fifty states, five U.S. territories, Washington DC, two Native American tribes, and sixteen Weatherization Innovation grantees); one-thousand and nine local weatherization agencies; approximately one thousand utilities; approximately two thousand residents; and approximately 2,913 individuals working in the weatherization field; (6) Estimated Number of Total Responses: 8,196; (7) Estimated Number of Total Burden Hours: The estimated burden is 67,000 hours; (8) Estimated Reporting and Recordkeeping Cost Burden: There is no reporting or recordkeeping cost burden associated with this request.

Authority: Section 6861 of title 42 of the United States Code and 10 CFR 440.25 authorize the collection of this information.

Issued in Washington, DC on March 3,

2011. Cathy Zoi, Assistant Secretary, Energy Efficiency and Renewable Energy.
