Energy Conservation Program: Energy Conservation Standards for Distribution Transformers; Correction

AGENCY:

Office of Energy Efficiency and Renewable Energy, Department of Energy.

ACTION:

Notice of proposed rulemaking and public meeting; correction.

SUMMARY:

The U.S. Department of Energy (DOE) published a notice of proposed rulemaking on February 10, 2012, which proposed to amend DOE regulations regarding energy conservation standards for distribution transformers. It was recently discovered that values in certain tables of the proposed rule are inaccurate or absent. This notice corrects these inaccuracies as described.

DATES:

DOE will accept comments, data and information regarding this correction before and after the February 23, 2012, public meeting, but no later than April 10, 2012.

SUPPLEMENTARY INFORMATION:

Background

Title III, Part B of the Energy Policy and Conservation Act of 1975 (EPCA or the Act), Public Law 94-163 (42 U.S.C. 6291-6309, as codified), established the Energy Conservation Program for "Consumer Products Other Than Automobiles." Part C of Title III of EPCA (42 U.S.C. 6311-6317) established a similar program for "Certain Industrial Equipment," including distribution transformers. The Energy Policy Act of 1992 (EPACT 1992), Public Law 102-486, amended EPCA and directed DOE to prescribe energy conservation standards for distribution transformers. (42 U.S.C. 6317(a)) On October 12, 2007, DOE published a final rule that established energy conservation standards for liquid-immersed distribution transformers and medium-voltage, dry-type distribution transformers (72 FR 58190). The Energy Policy Act of 2005 (EPACT 2005), Public Law 109-25, amended EPCA to establish energy conservation standards for low-voltage, dry-type distribution transformers. (42 U.S.C. 6295(y)) On February 10, 2012, DOE published a proposed rule with amended energy conservation standards for liquid-immersed, medium-voltage dry-type, and low-voltage, dry-type distribution transformers (77 FR 7282).

Need for Correction

As published, values in certain tables of the proposed rule are inaccurate or absent. DOE solicits public comment on the changes contained in this document as part of the February 10 NOPR.
