**Consumer Products and Certain Commercial and Industrial Equipment:**  **Notice of Policy Amendment Regarding Full-Fuel-Cycle Analyses** 

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

**ACTION :**  Notice of policy amendment.

**SUMMARY :**  On August 18, 2011, the U.S. Department of Energy (DOE) announced its intention to use full-fuel-cycle (FFC) measures of energy use and greenhouse gas and other emissions in the national impact analyses and environmental assessments included in future energy conservation standards rulemakings.
While DOE stated in that notice that it intended to use the Greenhouse Gases, Regulated Emissions, and Energy Use in Transportation (GREET) model to conduct the analyses, the Department
also said that it would review alternative methods, including the use of the National Energy Modeling System (NEMS) developed by DOE’s Energy Information Administration (EIA). After evaluating both NEMS and GREET, DOE has determined that NEMS is ultimately a more appropriate tool to calculate FFC measures of energy use and greenhouse gas and other emissions. Therefore, DOE intends to use the NEMS model, rather than the GREET model, as the basis for deriving the energy and emission multipliers used to conduct FFC analyses in support of future energy conservation standards rulemakings. The public is free to send in comments on this policy amendment at any time.
DOE will address comments on this policy amendment in the first notice of proposed rulemaking (NOPR) to utilize the NEMS-based approach for the FFC.

**SUPPLEMENTARY INFORMATION :**  I. Introduction and Discussion
On August 18, 2011, the U.S. Department of Energy (DOE) published a policy statement announcing its intention to use full-fuel-cycle (FFC) measures of energy use and greenhouse gas and other emissions in the national impact analyses and environmental assessments included in future energy conservation standards rulemakings. (76 FR 51281) While DOE stated in that
notice that it intended to use the Greenhouse Gases, Regulated Emissions, and Energy Use in Transportation (GREET) model to conduct the analysis, the Department also said that it would, from time to time, review alternative approaches to estimating these factors, including use of the National Energy Modeling System (NEMS) developed by DOE’s Energy Information Administration (EIA). (76 FR 51287) As indicated in the FFC policy statement notice, NEMS would continue to be utilized by DOE to estimate primary (or site) energy consumption for national impact analyses and environmental assessments, while GREET would be used to develop the energy and emission multipliers necessary to convert the NEMS-based primary energy and emission impacts into FFC values. Because of concerns about the potential
effects of certain inconsistencies in the underlying assumptions and forecasts used by GREET and NEMS, subsequent to publication of the policy statement,
DOE initiated a further review to determine whether NEMS (rather than GREET) might be used to develop the necessary FFC multipliers.

During this review process, DOE examined a new methodology to develop FFC multipliers using the data and projections generated by NEMS and published in EIA’s Annual Energy Outlook (AEO). While the AEO does not provide direct calculations of FFC metrics, it does provide extensive information about the energy system, including projections of future oil, natural gas and coal supply, energy use for oil and gas field and refinery operations, and fuel consumption and emissions related to electric power production. This information is used to define a set of parameters representing the amount of energy used in the fuel production chain. For example, the petroleum fuel production chain consists of extraction, separation, refining and distribution of final

Each of these process steps consumes energy in the form of diesel or fuel oil, natural gas, or grid electricity. The data are used to estimate an intensity parameter for each fuel type, which is equal to the total amount of that fuel needed to produce one unit of the final product. The FFC energy and emissions factors are defined as a function of these parameters, using
a formula that is described in detail in: ‘‘A Mathematical Analysis of Full Fuel Cycle Energy Use’’; [http://
www.sciencedirect.com/science/article/ pii/S0360544211006803] 1 Energy, Volume 37, Issue 1, January 2012, Pages

698–708;

By using the FFC multipliers derived from NEMS, DOE would be able to ensure that the assumptions and inputs used in FFC analyses are consistent with the assumptions and inputs used to estimate primary energy savings and emissions impacts. In addition, this approach would make it easier for DOE to update the multipliers with each new edition of the AEO. The GREET model, in contrast, uses a representation of the energy production system to develop its own internal projections, which inevitably will differ some from those in
the AEO.

Based on this assessment, DOE is proposing to use this NEMS-based approach to estimating the FFC energy and emission impacts of alternative energy conservation standards levels in energy conservation standards rulemakings that reach the notice of proposed rulemaking (NOPR) stage after August 17, 2012. Rulemakings that do not reach the NOPR stage before August 17, 2012 will continue to use the estimates of primary energy and emission impacts described in the notices of proposed rulemaking. DOE
has not used the GREET model to estimate FFC energy and emission impacts in any past or current rulemakings but has started to use the NEMS-based approach to estimating these impacts in several energy conservation standards preliminary analyses.

II. Public Participation

DOE invites all interested parties to
submit comments on this issue in writing at any time. In addition, interested parties will have an opportunity to review and comment on the specific methodologies employed by DOE to calculate FFC energy and emission impacts in NOPRs. See the

**ADDRESSES** section of this notice for more information on how to submit a

comment.

III. Procedural Issues and Regulatory

Review

A. Review Under the National Environmental Policy Act 1969

DOE has determined that this policy

amendment 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 policy
amendment describes methods for data analysis and how DOE plans to incorporate such data analysis into future energy conservation standards. For this reason, and because the policy amendment does not establish an energy conservation standard or take any action that might have an impact on the environment, it is covered by the Categorical Exclusion A9 under 10 CFR part 1021, subpart D. Accordingly,
neither an environmental assessment nor an environmental impact statement is required.

B. Review Under the Information Quality Bulletin for Peer Review

In consultation with the Office of Science and Technology Policy (OSTP), OMB issued on December 16, 2004, its ‘‘Final Information Quality Bulletin for Peer Review’’ (the Bulletin). 70 FR 2664 (Jan. 14, 2005). The Bulletin establishes
that certain scientific information shall be peer reviewed by qualified specialists before it is disseminated by the Federal government, including influential scientific information related to agency regulatory actions. The purpose of the Bulletin is to enhance the quality and credibility of the government’s scientific information. Under the Bulletin, NEMS is ‘‘influential scientific information,’’
which the Bulletin defines as ‘‘scientific information that the agency reasonably
can determine will have or does have a clear and substantial impact on important public policies or private sector decisions.’’ 70 FR 2664, 2667 (Jan. 14, 2005). The NEMS model, which is in the public domain, has been reviewed through its development and applications over the past 18 years.

IV. Approval of the Office of the Assistant Secretary

The Assistant Secretary of DOE’s Office of Energy Efficiency and Renewable Energy has approved publication of this final policy. Issued in Washington, DC, on August 9,

2012. Kathleen B. Hogan, Deputy Assistant Secretary for Energy Efficiency, Energy Efficiency and Renewable Energy.

**Airworthiness Directives; Embraer S.A. Airplanes** 

**AGENCY :**  Federal Aviation Administration (FAA), Department of Transportation (DOT).

**ACTION :**  Final rule.

**SUMMARY :**  We are superseding two existing airworthiness directives (AD) for all Embraer S.A. Model ERJ 170 and ERJ 190 airplanes. Those ADs currently require revising the airplane flight manual (AFM) to introduce limitations for the use of auxiliary power unit (APU) bleed and to prohibit dispatch with a failed air management system (AMS) controller card. This new AD requires replacing the AMS controller processor module with one containing new software, and a new AFM revision. This AD was prompted by reports of the possible loss of automatic activation of the engine inlet ice protection system. We are issuing this AD to prevent the possibility of a right-hand (RH) engine compressor stall after the APU becomes the active bleed source for the left side, which may result in an engine failure; and to prevent the intermittent
communication failure between the
AMS controller cards and both secondary power distribution assemblies (SPDAs), which could lead
to the loss of automatic activation of the engine inlet ice protection system when flying in icing conditions, which could result in ice accretion in the engine inlet and subsequent dual engine failure.

**DATES :**  This AD becomes effective September 21, 2012.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of September 21, 2012.
