On May 16, 2012, the U.S. Department of Energy (DOE) published a final rule in the Federal Register that amended the energy conservation standards and test procedures for certain commercial heating, air-conditioning, and water-heating equipment. Due to a drafting error, there was a typographical error (i.e., an incorrect symbol) for one equipment class of computer room air conditioners in a table to the applicable test procedure provision. This final rule rectifies this error.

Energy Conservation Program for Certain Industrial Equipment: 
Energy Conservation Standards and Test Procedures for Commercial 
Heating, Air-Conditioning, and Water-Heating Equipment; Correction

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

ACTION: Final rule; technical correction.

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

SUMMARY: On May 16, 2012, the U.S. Department of Energy (DOE) published 
a final rule in the Federal Register that amended the energy 
conservation standards and test procedures for certain commercial 
heating, air-conditioning, and water-heating equipment. Due to a 
drafting error, there was a typographical error (i.e., an incorrect 
symbol) for one equipment class of computer room air conditioners in a 
table to the applicable test procedure provision. This final rule 
rectifies this error.

DATES: Effective: March 5, 2015. The incorporation by reference of 
certain publications listed in the rule was approved by the Director of 
the Federal Register as of July 16, 2012.

SUPPLEMENTARY INFORMATION:

I. Background

    On May 16, 2012, DOE's Office of Energy Efficiency and Renewable 
Energy published an energy conservation standards and test procedure 
final rule in the Federal Register titled, ``Energy Conservation 
Standards and Test Procedures for Commercial Heating, Air-Conditioning, 
and Water-Heating Equipment'' (hereafter referred to as the ``May 2012 
final rule''). 77 FR 28928. Since the publication of that final rule, 
it has come to DOE's attention that, due to a technical oversight, the 
May 2012 final rule incorrectly included a typographical error 
regarding the symbol for one equipment class of the subject computer 
room air conditioners, which made it appear that there was more than 
one entry for that equipment class in the table showing the compliance 
date for use of the applicable test procedure. This final rule corrects 
this error, thereby eliminating the duplicative listing.

II. Need for Correction

    As published, the May 2012 final rule mischaracterizes one computer 
room air conditioner equipment class in the table showing the 
compliance date for use of the applicable test procedure. In the May 
2012 final rule, Table 2 on page 28990 contains a typographical error 
in the third column (``Cooling capacity'') for the equipment type, 
Computer Room Air Conditioners. The entry for the second line, 
``<65,000 Btu/h and <760,000 Btu/h,'' should be corrected to read 
``>=65,000 Btu/h and <760,000 Btu/h.'' At no place in the May 2012 
final rule did DOE discuss any intention to have two separate entries 
for computer room air conditioners <65,000 Btu/h in the test procedure, 
and DOE notes that this was a typographical error in the final rule as 
published in the Federal Register. Thus, the table has been corrected 
to eliminate this error. Accordingly, DOE finds that there is good 
cause under 5 U.S.C. 553(b)(B) to not issue a separate notice to 
solicit public comment on the changes contained in this document. 
Issuing a separate document to solicit public comment would be 
impractical, unnecessary, and contrary to the public interest.

III. Procedural Requirements

    DOE has concluded that the determinations made pursuant to the 
various procedural requirements applicable to the May 16, 2012 energy 
conservation standards and test procedure final rule for certain 
commercial heating, air-conditioning, and water-heating equipment 
remain unchanged for this final rule technical correction. These 
determinations are set forth in the May 16, 2012 final rule. 77 FR 
28928, 28983-86.
