# Chapter 6: **Results of Final**  **and Alternative Standards**  The heavy- duty

truck segment is very

complex. The sector consists of a diverse group of impacted parties, including engine manufacturers, chassis manufacturers, truck manufacturers, trailer manufacturers, truck fleet owners and the public. The final standards that the agencies have laid out today are largely shaped to maximize the environmental and fuel savings benefits of the program respecting the unique and varied nature of the sector . In developing this final rulemaking , we considered a number of alter natives that could have resulted in fewer or potentially

greater GHG and fuel consumption reductions than the program we are finalizing. This section summarizes the alternatives we considered and presents assessments of technology costs, CO 2 

### reductions, and fuel savings associated with each alternative. The agencies reduced the number of alternatives analyzed in this final rulemaking from those analyzed in the draft EIS and at proposal because we did not receive any comments supporting standard setting for a smaller subset than HD pickup trucks, combination tractors, and vocational vehicles . As discussed below, the agencies have refined some of the alternatives presented in the draft EIS and at proposal in response to the comments received. 

## 6.1 **What Are**  **the A** **lternatives that the Agencies Considered**  **?** In developing alternatives, NHTSA must consider EI SA's requirement for the MD/HD fuel efficiency

program noted above. 49 U.S.C. 32902(k)(2) and (3) contain the following three requirements specific to the MD/HD vehicle fuel efficiency improvement program: (1) The program must be “designed to achieve the maximum feasible improvement”; (2) the various required aspects of the program must be appropriate, cost- effective, and technologically feasible for MD/HD vehicles; and (3) the standards adopted under the program must provide not less than four model years of lead time and three model ye ars of regulatory stability . In considering these various requirements, NHTSA will also account for relevant environmental and safety considerations. Each of the alternatives presented b y NHTSA and EPA represents, in part, a different way the agencies could establish a HD program pursuant to EI SA and the CAA . The agenc ies are finalizing Alternative 3 . The alternatives below represent a broad range of approaches under consideration for finalizing the HD vehicle fuel efficiency and GHG emissions standards. The alternatives in order of increasing fuel efficiency and GHG emissions reductions are: 

## 6.1.1 **Alternative 1: No Action** A “no action” alternative assumes that the agencies would not issue a rulemaking regarding a MD/HD fuel efficiency improvement program, and is considered to comply with National Environmental Policy Act (NEPA) and to provide an analy tical baseline against which to compare environmental impacts of the other regulatory alternatives. 1 

### The agencies refer to this as the “No Action Alternative” or as a “no increase ” or “baseline” alternative. As described

### Regulatory Impact Analysis

6 - 2

in RIA Chapter 5, this no - action alternative is considered the reference case. The estimated fleet-wide fuel efficiency of this reference case is included in Table 6 - 1. **Table 6**  **- 1**  **Estimated F**  **leet -** **W ide**  **F uel**  **Efficienc y by**  **M odel**  **Y ear for Alternative 1 (** **B aseline)**  **[ gallon**  **s /100**  **mi les**  **]**

In this way, it provides a comparison between today ’s new trucks and the increased cost and reduced fuel consumption of future compliant vehicles. The agencies recognize that there is substantial uncertainty in determining an appropriate baseline against which to compare the effects of the proposed action. The lack of prior regulation of HD fuel efficiency means that there is a lack of historic data regarding trends in this sector. Therefore, in this final rulemaking the agencies have also included an analys is using a baseline derived from annual projections developed by the U.S. Energy

Information Administration (EIA) for the Annual Energy Outlook (AEO). For this alternative baseline, the agencies analyz ed the new truck fuel economy projections for Light Commercial Trucks, along with the Medium- and Heavy- Duty Freight Vehicles developed in AEO 2011. 2 

### The agencies converted the fuel economy improvements into CO 2 

### emissions reductions relative to a 2010 model year (see RIA Chapter 6). The baseline derived from the AEO forecast provides a comparison between the impacts of the proposed standards and EIA’s projection of future new truck performance absent regulation. This alternative baseline is informative in showing one possible projection of future vehicle performance based on other factors beyond the regulation the agencies are finalizing today . The AEO forecast makes a number of assumptions that should be noted. AEO 2011 assumes improved fuel efficiency for 8500 - 10,000 heavy- duty pi ckups due to the light- duty 2012 - 2016 MY vehicle rulemaking . We project a similar capability for fuel economy improvement as AEO does for this class of vehicles; however, the agencies recognize that absent regulation manufacturers may decline to add the necessary technologies to reach the level of our proposed standards . For medium and heavy- duty vocational vehicles , AEO 2011 projects a small reduction in fuel efficiency over time (an increase in fuel consumption), similar to that achieved under the MY 20 10 baseline. For Class 8 combination tractors, the AEO 2011 baseline projects an annual improvement of approximately 0.3 percent .

### 6 - 7 in order to meet two goals. First, we sought to create an alternative that regulated the same engine and vehicle categories as the preferred alternative , but at lower stringency (10 - 20 percent lower) than the preferred alternative. Second , we wanted an alternative that reflected removal of the least cost effective technology that we believed manufacturers would add last in order to meet the preferred alternative. In other words, we wanted an alternative that as closely as possible reflected the last increment in stringency prior to reaching our preferred alternative. Please see Table 2. 39 in RIA Chapter 2 for a list of all of the technologies, their cost and relative effectiveness. The resulting Alternative 2 is based on the same technologies used in Alternative 3 except as follows for each of the three categories. The combination tractor standard would be based on removal of the Bin IV aerodynamic package and weight reduction technologies which decreases the average combination tractor GHG emissions and fuel consumption reduction by approximately 1 percent. The road load impacts of this alternative are listed in Table 6 - 6 . **Table 6**  **- 6**  **Estimated Reductions in Rolling Resistance and Aerodynamic Drag Coefficients from Reference**  **Case for Alternative 2 (Model Years 2014 and Later)**

## 6.1.4 **Alternative 4**  **: 20**  **Percent More Stringent than**  **Preferred Alternative** Like Alternative s 2 and 3 , this alternative would set GHG emissions and fuel efficiency standards for HD pickup trucks and vans and for Class 2b through 8 vocational vehicles and combination tractors and the engines installed in them . The difference between Alternative 3 and 4 is the level of stringency for each of the standards. Alternative 4 represents a stringency level which is 20 percent more stringent than the preferred approach. The agencies derived the stringency

level based on similar goals as for Alternative 2 . Specifical ly, we wanted an alternative that would reflect an incremental improvement over the preferred alternative based on adding the next most cost effective technology in each of the categories. In general, we thought these were the technologies most likely to be applied by

manufacturers if a more stringent standard were set. However, as discussed in the feasibility discussion in Section III .A.2.vi, III.B, and III.C.2.v of the preamble to the final rules , we are not finalizing this level of stringency because we do not believe that there is adequate lead time for these technologies to be developed and introduced in the timeframe of this rulemaking. Reflecting that given unlimited resources it might be possible to introduce these technologies in this timeframe by, for example, constructing new factories in one to two years and otherwise operating entirely outside the normal redesign cycle , we are unable to estimate what those real costs might be (e.g. to build new factories in only one to two ye ars), we have denoted the cost for this alternative with a +c. The +c is intended to make clear that the cost estimates we are showing do not include additional costs related to pulling ahead the development and expanding manufacturing base for these technologies.

have we estimated the cost of the capital to do so, or whether capital would be available. See 75 FR at 25,451 (May

7, 2010). The resulting Alternative 4 is based on the same technologies used in Alternative 3 except as follows for each of the thre e categories. The combination tractor standard would be based on the addition of Rankine waste heat recovery (which, as the agencies have found will not be available in the time frame of this rulemaking ; see Section III.A.2.b.ii of the preamble and Chapter 2.4.2.7 of this RIA) and 100 percent application of Bin IV aerodynamics to high roof sleeper cab combination tractors . The agencies assumed 59 percent of all combination tractors are long-haul tractors and of those, 80 percent are high roof sleeper cabs. The agencies assumed a 12 kWh waste heat recovery s ystem would reduce CO 2 

### emissions by 6 percent at a cost of $8,400 per truck. 4 

### The estimated reduction in CO 2 

### emissions from the engine for this alternative is included in Table 6 - 12 . The impact of 100 percent application of Bin IV aerodynamic technology package would lead to a total 20.7 percent reduction in Cd values for high roof sleeper cabs over a 2010 MY baseline tractor. The incremental cost of this technology over the preferred case is $ 1,027 for each high roof sleeper cab tractor . The impact of the aerodynamic package on the road load is included in Table 6 - 13 .

and thus interfere with a chief purpose of these vehicles) . The estimated total vehicle CO 2

## 6.1.5 **Alternative 5**  **: Maximum Technology Penetration**  **plus Trailers**  Alternative 5 builds on Alternative 4 through additional hy brid powertrain application rates in the HD sector and by adding a performance standard for fuel efficiency and GHG emissions of commercial trailers . This alternative includes all elements of Alternative 4, plus the application of additional hy brid powertrains to the pickup trucks, vans, vocational vehicles, and tractors. In addition, the agencies applied aerodynamic technologies to commercial box trailers, along with tire technologies for all commercial trailers. The agencies set the hybrid penetration for each category, as described in Table 6 - 17 . The agencies do not believe that it is possible to achieve hybrid technology penetration rates at or even near these levels in the timeframe of this rulemaking. However, we believe it is useful to consider what a future standard based on the use of such advanced technologies could achieve. As with Alternative 4, we include a +c in our cost estimates for this alternative to reflect additional costs not estimated b y the agencies. The agencies assumed that a hy brid powertrain would provi de a 32 percent reduction in CO 2 

### emissions and fuel consumption of a vocational vehicle at a projected cost of $ 26,667 per vehicle , based on the average of the NAS report findings for box trucks, bucket trucks, and refuse vehicles . 6 

### The agencies are projecting a cost of $9,000 per vehicle for the HD pickup trucks and vans with an effectiveness of 18 percent , again based on the NAS report. 6 

### The effectiveness of hybrid powertrains installed in tractors was assumed to be 10 percent at a cost of $25,000 based on the NAS report. 6 

### Lastly, the effectiveness of hyb rid powertrains installed in tractors was assumed to be 10 percent at a cost of $25,000 based on the NAS report. 6 

### For the analys is of vocational vehicles in this alternative, the agencies assumed that hy brid technology

would be applied only in diesel - fueled trucks. In HD pickups and vans, the agencies assumed that hybrid technology would be evenly divided between diesel and gasoline vehicles. **Table 6**  **- 17**  **: Hybrid Penetration by Vehicle Class** 

### MY 2014 MY 2017 HD Pickup Trucks & Vans 10,000 units 50% Vocational Vehicles 10,000 units 50% Combination tractors 0% 5 % The combination tractor technology package for Alternative 5 includes the preferred alternative technologies, waste heat recovery (assuming, contrary to our technical finding, that the technology

will be available) and Advanced SmartWay aerodynamic package used in Alternative 4, application of hy brid powertrains discussed above, in addition to a regulation for commercial trailers pulled by combination tractors . The agencies assumed a trailer program would mirror the SmartWay program and include tire and aerodynamic requirements . The agencies added low rolling resistance tires to all commercial trailers, which are assumed to have 1 5 percent lower rolling resistance than the baseline trailer tire and is equivalent to the target value required b y SmartWay . The aerodynamics of the box trailers were assumed to improve the coefficient of drag for the combination tractor-trailer by 10 percent through the applic ation of technologies such as trailer skirts and gap reducers. 7

### 6 - 13 reductions in drag coefficient and rolling resistance coefficient from the MY 2010 baseline. The agencies assessed the benefits of a commercial trailer regulation by changing the road load associated with the combination tractors. Table 6 - 18 describes the road load reductions. As stated above for hybrids, the agencies do not believe that it is possible to achieve technology penetration rates at or even near these levels in the timeframe of this rulemaking. However, we believe it is useful to consider what a future standard based on the use of such technologies could achieve. **Table 6**  **- 18**  **Estim ated Reductions in Rolling Resistance and Aerodynamic Drag Coefficients from** **Reference Case for Alternative 5 (Model Years**  **2014 and Later)**

brid powertrains in ten percent of tractors, plus the costs of trailers. The costs for the trailer program of Alternative 5 were derived based on the assumption that trailer aerodynamic improvements would cost $2,150 per trailer. This cost assumes side fairings and gap reducers and is based on the ICF cost estimate. 8 

### The agencies applied the aerodynamic improvement to only

box trailers, which represent approximately 60 percent of the trailer sales. The agencies used $ 528 per trailer for low rolling resistance based on the agencies’ estimate of $ 66 per tire in the tractor program. Lastly, the agencies assumed the trailer volume is equal to three times the tractor volume based on the 3:1 ratio of trailers to tractors in the market today . The fuel e fficienc y results for Alternative 5 are summarized in Table 6 - 1 9 . **Table 6**  **- 1**  **9 Estim** **ated F**  **leet -** **W ide**  **F uel**  **Efficiency by**  **M odel**  **Y ear for**  **Alternative 5**  **[ gallons/100**  **mi les]**

### NEPA requires agencies to consider a “no action” alternative in their NEPA analyses and to compare the effects of not taking action with the effects of the reasonable action alternatives to demonstrate the different environmental effects of the action alternatives. See 40 CFR 1502.2(e), 1502.14(d).CEQ has explained that “[T]he regulations require the analysis of the no action alternative even if the agency is under a court order or legislative command to act. This analysis provides a benchmark, enabling decision makers to compare the magnitude of environmental effects of the action alternatives. It is also an example of a reasonable alternative outside the jurisdiction of the agency which must be analyzed. [See 40 CFR 1502.14(c).] * * * Inclusion of such an analysis in the EIS is necessary to inform Congress, the public, and the President as intended by NEPA.
