**SUPPLEMENTARY INFORMATION :**  I. Background

The Energy Policy and Conservation Act (EPCA), as amended by section 312(c) of the Energy Independence and Security Act (EISA 2007), requires the DOE to prescribe a test procedure to measure the energy use of walk-incoolers and freezers (collectively, walkins). See 42 U.S.C. 6314(a). DOE recently satisfied this requirement by issuing a final rule establishing a test procedure for manufacturers to use when measuring the energy use or energy efficiency of certain walk-in components: panels, non-display doors, display doors, and refrigeration systems. See 76 FR 21580 (April 15, 2011) (final rule prescribing walk-in test procedures) and 76 FR 33631 (June 9, 2011) (notice containing corrected formulas).

Since the publication of that rulemaking, DOE recognized a need to clarify the date by which manufacturers must begin using the test procedure. The **SUMMARY** and **DATES** sections of the preamble text to the final rule stated that the test procedures will be mandatory for making representations of energy usage or energy efficiency starting October 12, 2011; that is, 180 days after publication of the test procedure final rule. In this notice, DOE proposes to add regulatory text to clarify that the compliance date for using the test procedure for certifications of compliance is the same as the date for compliance with the energy conservation standards currently under development. DOE plans to issue the final rule by 2012 and manufacturers must comply with these standards within three years of publication of the final rule. DOE may also provide for a delayed effective date if the Secretary determines this three-year period is inadequate. (42 U.S.C. 6313(f)(4)(B)) DOE is also proposing to add regulatory text to clarify that only component manufacturers are required to submit certifications of compliance with the current standards.

II. Need for Clarification

DOE is publishing this notice to address questions from walk-in manufacturers regarding how to comply with their certification requirements under 10 CFR part 429, subpart B and Appendix A, which collectively prescribe the process for manufacturers to follow when certifying their commercial equipment as compliant under the relevant energy conservation standards. DOE recently indicated that walk-in manufacturers must comply with these requirements starting on October 1, 2011. 76 FR 38287, 38292 (June 30, 2011). EPCA, through amendments established by the Energy Independence and Security Act of 2007, Pub. L. 140–110 (Dec. 19, 2007) (EISA 2007), specified a test procedure that must be followed when determining the insulation value of the insulating foam used in walk-in applications, and manufacturers have raised questions as to whether they should continue using these procedures when certifying their equipment or use the new procedures that DOE promulgated in April 2011.

EISA 2007 prescribed several design requirements for walk-ins and specified that the R value (a representation of the thermal insulating characteristics of insulating foam) shall be the 1/K factor multiplied by the thickness of the panel, and the K factor shall be based on ASTM test procedure C518–2004. EPCA also prescribed certain temperature conditions for calculating the R value. (42 U.S.C. 6314(a)(9)(A)) Since 2009, these design requirements and test procedure provisions currently apply to all newly manufactured walk-ins. See 42 U.S.C. 6314(a)(9). See also 10 CFR Part 431.306(a)–(b) and 10 CFR 304(b)(1)–(4).

In addition to the above provisions, EPCA requires that DOE issue a test procedure for walk-ins. See 42 U.S.C. 6314(a)(9)(b). As noted above, DOE complied with that requirement by publishing a final rule prescribing a test procedure that covers the various key components comprising a walk-in. See 76 FR 21580 and 76 FR 33631.

Although the April 2011 test procedure continues to remain effective under today’s proposal, the procedure prescribed by the EISA 2007 amendments must continue to be used by manufacturers for certificationpurposes. At this time, the statutorilyprescribed procedure for determining an R value must also continue to be used when making representations regarding the energy-related performance of the relevant walk-in components. To the extent that a manufacturer chooses to make representations regarding the energy-related performance of the relevant walk-in components beyond the R-value of the foam used in panels, the April 2011 test procedure must be used for those representations. Once energy conservation standards that are performance based are established in 2012 for walk-in equipment, manufacturers must exclusively use the April 2011 test procedure when certifying their components as well as when making representations regarding that equipment’s energy-related performance.

To clarify walk-in manufacturer responsibilities, DOE is proposing to add regulatory text to specify when the current and new test procedures must be used. DOE is also proposing additional language to clarify when tests must be performed on walk-in panels and when tests may be performed on insulation foam used in the construction of panels, but that has not yet been incorporated into a walk-in panel. DOE invites comment on its proposed resolution to this issue. Finally, DOE is also clarifying that manufacturers arenot and will not be required to test nonfoam members and/or edge regions using the ASTM C518 test procedure prescribed in EPCA. Non-foam members and edge regions are only considered in the U-factor testing using ASTM C1363, which is part of the new DOE test procedures.

In addition, DOE’s recent certification, compliance and enforcement rulemaking indicated that only manufacturers of walk-in cooler and freezer components are required to submit certification reports. 76 FR 38287, 38292 (June 30, 2011). As such, DOE is proposing to add regulatory text to clarify that the WICF component manufacturers are the entities responsible for certifying compliance to the Department.

Finally, DOE’s recent certification, compliance and enforcement rulemaking extended the compliance dates for certification of several types of commercial equipment. 76 FR 38287, 38292. Specifically, DOE extended the certification compliance date for manufacturers of metal halide lamp fixtures to October 1, 2011. Since the issuance of the final rule, additional information has come to the attention of the DOE regarding a lack of sufficient


### 48747 Federal Register / Vol. 76, No. 153 / Tuesday, August 9, 2011 / Proposed Rules

test data to support certification on the full sample required by DOE’s regulations. To provide parity with similarly situated manufacturers of other types of commercial equipment, DOE is proposing to extend the certification compliance date further for manufacturers of metal halide lamp fixtures, requiring submittal of a certification report no later than 1 year following publication of a final rule.

IV. Procedural Issues and Regulatory
Review

A. Review Under Executive Order 12866

This proposed rule has been determined not to be a ‘‘significant regulatory action’’ under section 3(f) of Executive Order 12866. Accordingly, this action was not subject to review under the Executive Order by the Office of Information and Regulatory Affairs (OIRA) in the Office of Management and Budget (OMB).
B. Review Under the Regulatory Flexibility Act

The Regulatory Flexibility Act (5
U.S.C. 601 et seq. ) requires preparation of an initial regulatory flexibility analysis (IRFA) for any rule that by law must be proposed for public comment, unless the agency certifies that the rule, if promulgated, will not have a significant economic impact on a substantial number of small entities. As required by Executive Order 13272, ‘‘Proper Consideration of Small Entities in Agency Rulemaking,’’ 67 FR 53461 (August 16, 2002), DOE published procedures and policies on February 19,


### 48748 Federal Register / Vol. 76, No. 153 / Tuesday, August 9, 2011 / Proposed Rules

2003, to ensure that the potential impacts of its rules on small entities are properly considered during the DOE rulemaking process. 68 FR 7990. DOE has made its procedures and policies available on the Office of the General Counsel’s Web site: http:// www.gc.doe.gov

.

DOE reviewed this proposed rule under the provisions of the Regulatory Flexibility Act and the procedures and policies published on February 19, 2003. This proposed rule would merely extend the compliance date of a rulemaking already promulgated. To the extent such action has any economic impact it would be positive in that it would allow regulated parties additional time to come into compliance. DOE did undertake a full regulatory flexibility analysis of the original test procedures rulemaking. That analysis considered the impacts of that rulemaking on small entities. As a result, DOE certifies that, if adopted, this proposed rule, which would clarify the application of the test procedures, would not have a significant economic impact on a substantial number of small
entities.

C. Review Under the National Environmental Policy Act

DOE has determined that this rule falls into a class of actions that are categorically excluded from review under the National Environmental Policy Act of 1969 (42 U.S.C. 4321 et

seq. ) and DOE’s implementing regulations at 10 CFR part 1021. Specifically, this rule amends an existing rule without changing its environmental effect and, therefore, is covered by the Categorical Exclusion in 10 CFR part 1021, subpart D, paragraph A5. Accordingly, neither an environmental assessment nor an environmental impact statement is required.

V. Approval of the Office of the Secretary

The Secretary of Energy has approved publication of today’s NOPR.

Discussion

In May 2008, we received a report of an uncontained separation of a first stage turbine disk, P/N 3107079–1. The disk was installed in a TPE331–11U turboprop engine. That disk, which has a 20,000-cycle life, failed after accumulating 8,314 cycles-in-service.The fracture revealed a large meltrelated oxide cluster inclusion in the web area of the disk, which occurred during the forging alloy melting process. The disk was produced from Waspaloy material, from Heat Lot 9–7121, which was melted by Special Metals in 1980. We have determined that approximately 360 turbine disks were produced from the same heat lot as the failed forged turbine disk and therefore may have similar inclusions. This condition, if not corrected, could result in uncontained failure of the first stage turbine disks made from these billets and damage to the airplane.

Relevant Service Information

We reviewed Honeywell International Inc. Alert Service Bulletin (ASB) TPE331–72–A2156, dated December 2, 2008. The Honeywell ASB TPE331–72– A2156, dated December 2, 2008, provides S/Ns of the affected turbine disks and describes procedures for initial and repetitive fluorescent penetrant inspection (FPI) and eddy current inspection (ECI) of the first stage turbine disk.

FAA’s Determination

We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design.
Proposed AD Requirements

This proposed AD would require:

• For turbine disks that have an S/N listed in Table 1 of this proposed AD with 4,100 or fewer cycles-since-new (CSN) on the effective date of this proposed AD, performing an initial FPI and ECI within 4,500 CSN or at the next access, whichever occurs first.

• For turbine disks that have an S/N listed in Table 1 of this proposed AD with more than 4,100 CSN on the effective date of this proposed AD, performing an initial FPI and ECI within 400 cycles-in-service after the effective date of this proposed AD or at the next access, whichever occurs first.

• Thereafter, for turbine disks that have an S/N listed in Table 1 of this proposed AD, perform a repetitive FPI and ECI at each scheduled hot section inspection, but not to exceed 3,600 hours-since-last inspection.

The proposed AD would require that you do these actions using the service information described previously.
