I. History of Standards Rulemakings for 

Metal Halide Lamp Fixtures and 

Regulatory Authority 

A. Background 

Title III of the Energy Policy and 

Conservation Act (EPCA) of 1975, 

Public Law 94–163, (42 United States 

Code (U.S.C.) 6291 et seq.) established 

an energy conservation program for 

major household appliances and 

industrial and commercial equipment. 

More specifically, Part B of Title III (42 

U.S.C. 6291–6309) establishes the 

‘‘Energy Conservation Program for 

Consumer Products Other Than 

Automobiles.’’ 1 Subsequent 

amendments to EPCA have given DOE 

the authority to regulate the energy 

efficiency of several additional kinds of 

equipment, including MHLFs, which 

are the focus of this document. 

The following summarizes the 

pertinent legislative and regulatory 

history for MHLFs. DOE is conducting 

its first rulemaking cycle to review and 

consider amendments to the energy 

conservation standards in effect for 

MHLFs, as required under 42 U.S.C. 

6295(hh)(2). 

By way of background, on December 

19, 2007, the President signed the 

Energy Independence and Security Act 

of 2007 (EISA 2007) which made 

numerous amendments to EPCA and 

directed DOE to undertake several new 

rulemakings for appliance energy 

conservation standards. (Pub. L. 110– 

140) The MHLF provisions, section 324 

of EISA 2007, amended EPCA by: 

• Inserting definitions pertaining to 

‘‘metal halide ballast,’’ 2 ‘‘metal halide 

lamp,’’ 3 and ‘‘metal halide lamp 

fixtures’’ 4 (among others) into section 

321 of EPCA (42 U.S.C. 6291(62), (63), 

and (64)); 

• Amending section 323(b) of EPCA 

to direct DOE to develop a test 

procedure for metal halide (MH) lamp 

ballasts based on the American National 

Standard Institute (ANSI) Standard 

C82.6–2005, Ballasts for High-Intensity 

Discharge (HID) Lamps-Methods of 

Measurement (42 U.S.C. 6293(b)(18)); 

• Amending section 324(a)(2) of 

EPCA by directing the Federal Trade 

Commission (FTC) to conduct a labeling 

rulemaking for MHLFs (42 U.S.C. 

6294(a)(2)(C)); and 

• Amending section 325 of EPCA by 

prescribing energy conservation 

standards for MHLFs, requiring that 

they contain ballasts that meet or exceed 

defined efficiency levels. Compliance 

with the EISA 2007-prescribed 

standards was required as of January 1, 

2009. (42 U.S.C. 6295(hh)(1)) As stated 

in the statutory language, the Secretary 

is directed to publish a final rule no 

later than January 1, 2012 to determine 

whether the energy conservation 

standards established by EISA 2007 for 

MHLFs should be amended, with any 

amendment applicable to products 

manufactured on or after January 1, 

2015. (42 U.S.C. 6295(hh)(2)(B)) 

The following statutory provisions are 

directly relevant to the energy 

conservation standards rulemaking for 

MHLFs. As amended by EISA 2007, 

EPCA regulates MHLFs designed to be 

operated with lamps rated greater than 

or equal to 150 watts (W), but less than 

or equal to 500 W by prescribing 

performance requirements for the MH 

lamp ballasts used in those MHLFs. 

Both MH lamps and ballasts are energyusing components of MHLFs. For this 

MH lamp wattage range, MHLFs must 

contain the ballasts described at 42 

U.S.C. 6295(hh)(1)(A). 

In addition to prescribing minimum 

efficiency requirements for the 

previously described MH lamp ballasts 

contained in MHLFs, EISA 2007 

amended EPCA to exclude certain types 

of MH lamp fixtures from the statutorily 

prescribed energy conservation 

standards as described at 42 U.S.C. 

6295(hh)(1)(B). 

Pursuant to section 310 of EISA 2007, 

EPCA further directs DOE to incorporate 

standby mode and off mode energy use 

in any amended (or new) standard 

adopted after July 1, 2010. (42 U.S.C. 

6295(gg)(3)) Because this energy 

conservation standards rulemaking must 

be completed by January 1, 2012, the 

requirement to incorporate standby 

mode and off mode energy use into the 

energy conservation standards analysis 

is applicable. The application of 

standby mode and off mode energy use 

in this rulemaking is discussed in detail 

in the TSD. 

The following statutory provisions 

(and associated rulemakings) are related 

to MHLFs but are separate from the 

current standards rulemaking: 

• In conjunction with energy 

conservation standards for MHLFs, 

EPCA required DOE to undertake a 

determination to see if energy 

conservation standards for High 

Intensity Discharge (HID) lamps 

(including MH lamps) would be 

technologically feasible and 

economically justified, and would result 

in significant energy savings. (42 U.S.C. 

6317(a)(1)) DOE completed the HID 

determination and published a final rule 

(75 FR 67975) on July 1, 2010 

concluding that energy conservation 

standards for certain HID lamps are 

technologically feasible and 

economically justified. 

• DOE completed a test procedure 

rulemaking for MH lamp ballasts, as 

required by EPCA through amendments 

from EISA 2007. (42 U.S.C. 6293(b)(18)) 

The final rule test procedure for MH 

lamp ballasts was published in the 

Federal Register on March 10, 2010. 75 

FR 10950. 

• The FTC is directed to conduct a 

labeling rulemaking as part of the 

requirements set forth by EISA 2007 for 

MHLFs. (42 U.S.C. 6294(a)(2)(C)) To this 

end, the FTC published a final rule in 

the Federal Register on July 9, 2008, 

amending 16 CFR part 305, ‘‘Rule 

Concerning Disclosures Regarding 

Energy Consumption and Water Use of 

Certain Home Appliances and Other 

Products Required Under the Energy 

Policy and Conservation Act 

(‘Appliance Labeling Rule’).’’ 73 FR 

39221. On October 23, 2008, the FTC

Federal Register / Vol. 76, No. 63 / Friday, April 1, 2011 / Proposed Rules 18129 

published in the Federal Register 

additional amendments to 16 CFR part 

305 for MHLFs in the form of technical 

corrections. 73 FR 63066. Both final 

rules fulfilled the FTC’s obligations 

under EISA 2007 pertaining to labeling 

requirements for MHLFs and MH lamp 

ballasts. 

B. Current Rulemaking Process 

On December 30, 2009, DOE 

published a notice announcing the 

availability of the framework document, 

‘‘Energy Conservation Standards 

Rulemaking Framework Document for 

Metal Halide Lamp Fixtures,’’ and a 

public meeting to discuss the proposed 

analytical framework for the 

rulemaking. 74 FR 69036. DOE also 

posted the framework document on its 

Web site describing the procedural and 

analytical approaches DOE anticipated 

using to evaluate the establishment of 

energy conservation standards for 

MHLFs. This document is available at 

http://www1.eere.energy.gov/buildings/ 

appliance_standards/commercial/pdfs/ 

mh_ecs_framework.pdf. 

DOE held a public meeting on January 

26, 2010, to describe the various 

rulemaking analyses DOE would 

conduct, such as the engineering 

analysis, the life-cycle cost (LCC) and 

payback period (PBP) analyses, and the 

national impact analysis (NIA); the 

methods for conducting them; and the 

relationship among the various 

analyses. Manufacturers, trade 

associations, and environmental 

advocates attended the meeting. The 

participants discussed multiple issues 

including the scope of covered MHLFs, 

test procedures, a system approach and 

ballast efficiency metric, DOE’s 

engineering analysis, LCCs, efficiency 

levels, and energy savings. 

Comments received since publication 

of the framework document have helped 

DOE identify and resolve issues 

involved in the preliminary analyses. 

Chapter 2 of the preliminary TSD 

summarizes and addresses the 

comments DOE received. 

II. Summary of the Analyses 

DOE conducted in-depth technical 

analyses in the following areas for the 

MHLFs currently under consideration: 

(1) Engineering, (2) energy use 

characterization, (3) markups to 

determine product price, (4) LCC and 

PBP, and (5) national impact. The 

preliminary TSD presents the 

methodology and results of each 

analysis. The analyses are described in 

more detail below. 

DOE conducted several other analyses 

that either support the five major 

analyses or are preliminary analyses 

that will be expanded in the Notice of 

Proposed Rulemaking (NOPR). These 

include the market and technology 

assessment; the screening analysis, 

which contributes to the engineering 

analysis; and the shipments analysis, 

which contributes to the NIA. DOE has 

begun some preliminary work on the 

manufacturer impact analysis and 

identified the methods to be used for the 

LCC subgroup analysis, the 

environmental assessment, the 

employment analysis, the regulatory 

impact analysis, and the utility impact 

analysis. DOE will expand on these in 

the NOPR. 

A. Engineering Analysis 

The engineering analysis establishes 

the relationship between manufacturer 

selling price and equipment efficiency. 

This relationship serves as the basis for 

cost-benefit calculations for individual 

consumers, manufacturers, and the 

nation. The engineering analysis 

identifies representative baseline 

models, which is the starting point for 

analyzing technologies that provide 

energy efficiency improvements. A 

baseline model refers to a model (or 

models) having features and 

technologies typically found in 

equipment currently offered for sale. 

The baseline model in each equipment 

class represents the characteristics of 

certain MHLFs in that class and, for 

fixtures already subject to energy 

conservation standards, is usually a 

model that just meets the current 

standard. Chapter 5 of the preliminary 

TSD discusses the engineering analysis. 

B. Energy Use Characterization 

The energy use characterization 

provides estimates of annual energy 

usage for MHLFs, which DOE uses in 

the LCC and PBP analyses and the NIA. 

DOE developed energy usage estimates 

for all of the equipment classes analyzed 

in the engineering analysis as the basis 

for its energy use estimates. Chapters 2 

and 6 of the preliminary TSD provide 

detail on the energy use 

characterization. 

C. Markups To Determine Installed 

Price 

DOE derives the installed prices for 

equipment based on manufacturer 

markups, retailer markups, distributor 

markups, contractor markups, builder 

markups, and sales taxes. In deriving 

these markups, DOE has determined the 

distribution channels for product sales, 

the markup associated with each party 

in the distribution channels, and the 

existence and magnitude of differences 

between markups for baseline 

equipment (baseline markups) and for 

more efficient equipment (incremental 

markups). DOE calculates both overall 

baseline and overall incremental 

markups based on the equipment 

markups at each step in the distribution 

channel. The overall incremental 

markup relates the change in the 

manufacturer sales price of higher 

efficiency models (the incremental cost 

increase) to the change in the retailer or 

distributor sales price. Chapters 2 and 7 

of the preliminary TSD provide detail 

on the estimation of markups. 

D. Life-Cycle Cost and Payback Period 

Analyses 

The LCC and PBP analyses determine 

the economic impact of potential 

standards on individual consumers. The 

LCC is the total consumer expense for 

equipment over its lifetime. The LCC 

analysis compares the LCCs of 

equipment designed to meet possible 

energy conservation standards with the 

LCCs of equipment likely to be installed 

in the absence of standards. DOE 

determines LCCs by considering (1) 

Total installed cost to the purchaser 

(which consists of manufacturer selling 

price, sales taxes, distribution chain 

markups, and installation cost); (2) the 

operating expenses of the equipment 

(energy use and maintenance); (3) 

equipment lifetime; and (4) a discount 

rate that reflects the real consumer cost 

of capital and puts the LCC in presentvalue terms. The PBP represents the 

number of years needed to recover the 

increase in purchase price (including 

installation cost) of more efficient 

equipment through savings in the 

operating cost. PBP is equal to the 

change in total installed cost due to 

increased efficiency divided by the 

change in annual operating cost from 

increased efficiency. Chapters 2 and 8 of 

the preliminary TSD provide detail on 

the LCC and PBP analyses. 

E. National Impact Analysis 

The NIA estimates the national energy 

savings (NES) and the net present value 

(NPV) of total consumer costs and 

savings expected to result from new 

standards at specific efficiency levels 

(referred to as candidate standard 

levels). DOE calculated NES and NPV at 

each efficiency level for each candidate 

standard for MHLFs as the difference 

between a base-case forecast (without 

new standards) and the standards-case 

forecast (with standards). DOE 

determined national annual energy 

usage by multiplying the number of 

units in use (by vintage) by the average 

unit energy usage (also by vintage). 

Cumulative energy savings are the sum 

of the annual NES determined over a 

specified time period. The national NPV 


jlentini on DSKJ8SOYB1PROD with PROPOSALS
18130 Federal Register / Vol. 76, No. 63 / Friday, April 1, 2011 / Proposed Rules 

is the sum over time of the discounted 

net savings each year, which consists of 

the difference between total operating 

cost savings and increases in total 

installed costs. Critical inputs to this 

analysis include shipments projections, 

retirement rates (based on estimated 

product lifetimes), and estimates of 

changes in shipments and retirement 

rates in response to changes in product 

costs due to standards. Chapters 2 and 

10 of the preliminary TSD provide 

detail on the NIA. 

DOE consulted with interested parties 

on all of the analyses and invites further 

input on these topics. The preliminary 

analytical results are subject to revision 

following review and input from the 

public. A revised TSD will be made 

available upon issuance of a NOPR. The 

final rule will contain the final analysis 

results and be accompanied by a final 

rule TSD. 

DOE encourages those who wish to 

participate in the public meeting to 

obtain the preliminary TSD and be 

prepared to discuss its contents. 

However, public meeting participants 

need not limit their comments to the 

topics identified in the preliminary 

TSD. DOE is also interested in receiving 

information on other relevant issues that 

participants believe would affect energy 

conservation standards for this 

equipment or that DOE should address 

in the NOPR. 

DOE welcomes all interested parties, 

regardless of whether they participate in 

the public meeting, to submit comments 

and information in writing by May 16, 

2011. 

The public meeting and associated 

Webinar will be conducted in an 

informal, conference style. A court 

reporter will be present to record the 

minutes of the meeting. There shall be 

no discussion of proprietary 

information, costs, prices, market 

shares, or other commercial matters 

regulated by U.S. antitrust laws. 

After considering all comments and 

additional information it receives from 

interested parties or through further 

analyses, DOE will prepare and publish 

in the Federal Register a NOPR. The 

NOPR will include proposed energy 

conservation standards for the 

equipment covered by the rulemaking. 

Members of the public will have an 

opportunity to submit written and oral 

comments on the proposed standards.

Background 

On August 26, 2010, Turbomeca 

applied for type certification for a new 

model Arriel 2D turboshaft engine. This 

engine consists of an axial air intake, an 

axial compressor and a centrifugal 

compressor driven by a single-stage 

turbine, a direct-flow annular 

combustion chamber, and a single-stage 

free turbine which drives a reduction 

gear assembly located at the rear end. 

The accessory gearbox, located at the 

front end, is driven by the gas generator 

turbine. 

The engine will incorporate a novel or 

unusual design feature, which is a 30- 

minute power rating. This rating was 

requested by the applicant to support 

rotorcraft search and rescue missions 

that require extensive operations at high 

power. This type of rating is generally 

associated with multi-engine
