## Chapter 9. **Economic and Other Impacts**  **9.1 Framework** 

**for Benefits and Costs** The net benefits of the HD National Program consist of the effects of the program on:

• the engine and truck program costs ,

• fuel savings associated with reduced fuel usage resulting from the program ,

• greenhouse gas emissions,

• other air pollutants,

• noise, congestion, accidents resulting from truck use ,

• refueling savings ,

• energy

security impacts,

• increased driving due to the “rebound” effect. The benefits and costs of this rule are anal yz ed using 3 percent and 7 percent discount rates. These rates are intended to represent the social opportunity cos ts of capital; they

are not necessarily

the discount rates that private decision - makers use. 

### 9.2 **Conceptual Framework for Evaluating Impacts** This regulation is motivated primarily by the goals of reducing emissions of greenhouse gases and promoting U.S. energy security b y reducing consumption and imports of petroleum based fuels. These motivations involve classic externalities, meaning that private decisions do not incorporate all of the costs associated with these problems; these costs are not borne completel y b y the households or businesses whose actions are responsible for them. In the absence of some mechanism to “internalize” these costs

– that is, to transfer their burden to individuals or firms whose decisions impose them

– individuals and firms will co nsume more petroleum - based fuels than is socially optimal. Externalities are a classic motivation for government intervention in markets. These externalities, as well as effects due to changes in emissions of other pollutants and other impacts, are discu ssed in Sections VIII.H

– VIII.K. In some cases, these classic externalities are by themselves enough to justify the costs of imposing fuel efficiency

standards. F or some discount rates and some projected social costs of carbon, however, the reductions in these external costs are less than the costs of new fuel saving technologies needed to meet the standards . (See T able s 9 - 18 and 9 - 1 9 in the RIA .) Nevertheless , th is regulation reduces trucking companies’ fuel costs; according to our estimates, these savings**Regulatory Impact Analysis**

9 - 2

in fuel costs are by themselves sufficient to pay for the technologies over periods of time considerabl y shorter than vehicles’ expected lifetimes under the assumptions used for this anal ys is (e.g., AEO 2011 projected fuel prices). If these estimate s are correct, then the entire value of the reductions in external costs represents additional net benefits of the program, beyond those resulting from the fact that the value of fuel savings exceeds the costs of technologies necessary to achieve them. It is often asserted that there are cost - effective fuel - saving technologies that markets do not take advantage of

. This is commonly

known as the “energy gap” or “energy paradox.” S tandard economic theory suggests that in normally functioning competitive mar kets, interactions between vehicle buyers and producers would lead producers to incorporate all cost effective technology

into the vehicles that they offer, without government intervention. Unlike in the light - duty

vehicle market, the vast majority of vehicles in the medium - and heavy- duty truck market are purchased and operated b y businesses with narrow profit margins, and for which fuel costs represent a substantial operating expense. Even in the presence of uncertainty and imperfect information

– conditions that hold to some degree in every

market

– we generally

expect firms to attempt to minimize their costs in an effort to survive in a competitive marketplace, and therefore to make decisions that are in the best interest of the company and its owners and/or shareholders. In this case, the benefits of the rules would be due exclusively to reducing the economic costs of externalities resulting from fuel production and consumption. However, as discussed below in Section VIII. E, the agencies have estimated that the application of fuel - saving technologies in response to the final standards would , on average, yi eld private returns to truck owners of 140 percent to 420 percent (see Table VIII - 21 below). The agencies have also estimated that the application of these technologies would be significantly

lower in the absence of the final standards ( i.e. , under the “no action” regulatory

alternative), meaning that truck buyers and operators ignore opportunities to make investments in higher fuel efficiency that appear to offer significant cost savings . As discussed in the NPRM, there are several possible explanations in the economics literature for why

trucking companies do not adopt technologies that would be expected to increase their profits: there could be a classic market failure in the trucking industry

– market power, externalities, or asy mmetric or incomplete (i.e., missing market) information; there could be institutional or behavioral rigidities in the industry (union rules, standard operating procedures , statutory

requirements, loss aversion, etc.), whereb y participants collective ly do not minimize costs; or the engineering estimates of fuel savings and costs fo r these technologies might overstate their benefits or understate their costs in real - world application s . To try to understand why trucking companies have not adopted these seemingl y cost effective fuel - saving technologies, the agencies surveyed published literature about the energy paradox, and held discussions with numerous truck market participants. The proposal discussed five categories of possible explanations derived from these sources . Collectively , these five hy potheses may explain the apparent inconsistency between the engineering anal ys is, which finds a number of cost - effective methods of improving fuel efficiency , and the observation that many of these technologies are not widely adopted.******* **E.O. 12866 Review –**  **Revised Version –**  **Do Not Cite, Quote, or Release During Review** *******

9 - 3 These hypotheses include imperfect information in the original and resale markets, split incentives, uncertainty

about future fuel prices, and adjustment and transactions costs. As the discussion indicated, some of these explanations suggest failures in the private market for fuel saving technology

in addition to the externalities caused by producing and consuming fuel that are the primary

motivation for the rules. Other explanations suggest market - based behaviors that may impl y additional costs of regulating truck fuel efficiency that are not accounted for in this anal ys is. As noted above, an additional explanation

– adverse effects on other vehicle attributes

-- did not elicit supporting information in the public comments. Anecdotal evidence from various segments of the trucking industry suggests that many

of the hy potheses discussed here may play a role in explaining the puzzle of why truck purchasers appear to under- invest in fuel efficiency , although different explanations may apply to different segments, or even different companies. The published literature does not appear to include empirical analysis or data related to this question. The agencie s invite d comment on these explanations, and on any data or information that could be used to investigate the role of any or all of these five hypotheses in explaining this energy paradox as it applies specificall y to trucks . Some comments expressed dissatisfaction about the explanations presented; they argued that these arguments were not sufficient to explain the phenomenon. These comments argued that the truck owners and operators are better judges of the appropriate amount of fuel efficiency than are government agencies; they choose not to invest because of warranted skepticism about these technologies. The agencies also request ed comment and information regarding any other hy potheses that could explain the appearance that cost - effective fuel - saving t echnologies have not been widel y incorporated into trucks . The following discussion summarizes the fuller discussion provided in the NPRM and includes discussion of the comments received. 

### 9.2.1 **Information Issues in the Original Sale Markets** One potential hypothesis for why the trucking industry does not adopt what appear to be inexpensive fuel saving technologies is that there is inadequate or unreliable information available about the effectiveness of many fuel - saving technologies for new vehicles. If reliabl e information on the effectiveness of many new technologies is absent, truck buyers will understandabl y be reluctant to spend additional money to purchase vehicles equipped with unproven technologies. This lack of information can manifest itself in multiple way s. For instance, the problem may arise purely because collecting reliable information on technologies is costly (also see Section VIII.A. 5 on transaction costs). Moreover, information has aspects of a public good , in that no single firm has the in centive to do the costly experimentation to determine whether or not particular technologies are cost - effective, while all firms benefit from the knowledge that would be gained from that experimentation. Similarly, if multiple firms must conduct the same tests to get the same information, costs could be reduced by some form of coordination of information gathering. While its effect on information is indirect, we expect the requirement for the use of new technologies included in this program will circumvent these information issues, resulting in their adoption, thus providing more readily available information about their benefits. The agencies**Regulatory Impact Analysis**

9 - 4

appreciate, however, that the diversity of truck uses, driving situations, and driver behavior will lead to variation in the fuel savings that individual trucks or fleets experience from using specific technologies. One commenter noted that the SmartWay program targets semi - truck owners and thus should have the largest impact on that sector, rather than vocational o r medium - duty trucks. However, the gap between actual investment in fuel efficiency and the agencies’ estimates of optimal investment is largest for combination tractors. Some of the difference in magnitude is likely to be due to the higher vehicle miles traveled for semi - trucks compared to medium - duty and vocational vehicles: more driving means more fuel savings. Additionally , not even a majority of semi - trucks are owned b y participants in SmartWay ; non - participants are unlikel y to get all the benefits of participants. Other explanations, noted below, are also likely to play a role. This observation may

also suggest some limitations of improved information provision as a means of addressing the “efficiency gap.” 

### 9.2.2 **Information Issues in the Resale Market** In addition to issues in the new vehicle market, a second hypothesis for why trucking companies may

not adopt what appear to be cost - effective technologies to save fuel is that the resale market may

not adequatel y reward the addition of fuel - saving techno logy to vehicles to ensure their original purchase b y new truck buye rs. This inadequate pay back for users beyond the original owner may

contribute to the short payback period that new purchasers appear to expect. 1 The agencies requested data and information on the extent to which costs of fuel saving equipment can be recovered in the resale truck market. No data were received. One reviewer disputed this theory

on the basis that people are willing to pay more for better vehicles, new or used. It is not clear, however, whether buye rs of used vehicles can tell which are the better vehicles. 2 Some of this unwillingness to pay for fuel - saving technology may be due to the extension of the information problems in the new vehicle market into resale markets. Buyers in the resale market have no more reason to trust information on fuel - saving technologies than buyers in the original market. Because actual fuel efficiency of trucks on the road depends on many factors, including geography and driving styl es or habi ts, even objective sources such as logs of truck performance for used vehicles may not provide reliable information about the fuel efficiency that potential purchasers of used trucks will experience. A related possibility

is that vehicles will be used for different purposes b y their second owners than those for which they were originall y designed, and the fuel - saving technology is therefore of less value. It is possible, though, that the fuel savings experienced by the secondary

purchasers may not match those experienced b y their original owners if the optimal secondary new use of the vehicle does not earn as many benefits from the technologies. One commenter asks whether the fuel - saving technology

is unvalued because it is unproven or overrated. In that case, the premium for fuel - saving technology in the secondary

market should accurately reflect its value to potential buyers participating in that market, even if it is lower than its value in the original market, and the market has not failed. Because the information necessary to optimize use in the******* **E.O. 12866 Review –**  **Revised Version –**  **Do Not Cite, Quote, or Release During Review** *******

9 - 5 secondary market may

not be readil y available or reliable, however, buye rs in the resale market may have less ability than purchasers of new vehicles to identify and gain the advantages of new fuel - saving te chnologies, and may thus be even less likely

to pay a premium for them. For these reasons, purchasers’ willingness to pay for fuel efficiency

technologies may

be even lower in the resale market than in the original equipment market. Even when fuel - saving technologies will provide benefits in the resale markets, purchasers of used vehicles may not be willing to compensate their original owners fully for their remaining value. As a result, the purchasers of original equipment may expect the resale market to provide inadequate appropriate compensation for the new technologies, even when those technologies would reduce costs for the new buyers. This information issue may partially explain what appears to be the very short pay back periods required for new technologies in the new vehicle market. 

### 9.2.3 **Split I**  **ncentives in the M**  **edium -**  **and H**  **eavy -**  **D uty**  **T ruck**  **I ndustry**  A third hy

pothesis explaining the energy paradox as applied to trucking involves split incentives. When markets work effectivel y, signals provided by transac tions in one market are quickly transmitted to related markets and influence the decisions of buyers and sellers in those related markets. For instance, in a well - functioning market s ys tem, changes in the expected future price of fuel should be transmitte d rapidl y to those who purchase trucks, who will then reevaluate the amount of fuel - saving technology to purchase for new vehicles. If for some reason a truck purchaser will not be directly responsible for future fuel costs, or the individual who will be responsible for fuel costs does not decide which truck characteristics to purchase, then those price signals may not be transmitted effectivel y, and incentives can be described as “split.” One place where such a split may occur is between the owners and operators of trucks. Because they

are generally

responsible for purchasing fuel, truck operators have strong incentives to economize on its use, and are thus likely to support the use of fuel - saving technology . However, the owners of trucks or trailers are often different from operators, and may be more concerned about their longevity or maintenance costs than about their fuel efficiency , when purchasing vehicles. As a result, capital investments by truck owners may

be channeled into equipment that improv es vehicles’ durability or reduces their maintenance costs, rather than into fuel - saving technology . If operators can choose freel y am ong the trucks they drive, competition among truck owners to employ operators would encourage owners to invest in fuel - saving technology . However, if truck owners have more ability to choose among operators, then market signals for improved fuel savings that would normally be transmitted to truck owners may

be muted. Truck fleets that rent their vehicles may provide an example: renters may observe the cost of renting the truck, but not its fuel efficiency ; if so, then the purchasers will aim for vehicles with lower costs, to lower the cost of the rental. It might be possible to test this theory

by comparing the fuel effic iency of trucks by

owner - operators with those that are leased b y operators. The agencies have not had the data to conduct such a test. One commenter noted that there are always tradeoffs in an investment decision: a purchaser may

prefer to invest in other vehicle attributes than fuel efficiency. In an efficient market, however, a purchaser should invest in fuel - saving technology as long as the increase in fuel - saving technology

costs less than the expected fuel savings. This result should hold**Regulatory Impact Analysis**

9 - 6

regardles s of the level of investment in other attributes, unless there are constraints on a purchaser’s access to investment capital. The agencies believe that truck fleets do have an incentive to make investments in fuel efficiency , and that this assumption is reflected in the regulatory

anal ys is. The agencies also believe, however, that sufficient evidence suggests that truck fleets are not availing themselves of all the opportunities for efficiency improvements. In addition, the NAS report notes that split inc entives can arise between tractor and trailer operators. 3 Trailers affect the fuel efficiency of shipping, but trailer owners do not face strong incentives to coordinate with truck owners. EPA and NHTSA are not regulating trailers in this action. By

itse lf, information provision may be inadequate to address the potential underinvestment in fuel efficiency resulting from such split incentives. In this setting, regulation may contribute to fuel savings that otherwise may be difficult to achieve. 

### 9.2.4 **Uncertaint y A** **bout Future Cost Savings** Another hypothesis for the lack of adoption of seemingl y fuel saving technologies may be uncertainty

about future fuel prices or truck maintenance costs . When purchasers have less than perfect foresight about future operating e xpenses , they may implicitly

discount future savings in those costs due to uncertainty about potential returns from investments that reduce future costs. In contrast, the immediate costs of the fuel - saving or maintenance - reducing technologies are certain and immediate, and thus not subject to discounting . Inthis situation, both the expected return on capital investments in higher fuel efficiency and potential variance about its expected rate may play a role in a firm’s calculation of its pay back period o n such investments. In the context of energy efficiency investments for the home, Metcalf and Rosenthal (1995) and Metcalf and Hassett (1995) observe that households weigh known, up - front costs that are essentially

irreversible against an unknown stream of future fuel savings. 4 Notably , in this situation, requiring households to adopt technologies more quickl y may make them worse off by imposing additional risk on them . Greene et al (2009) also find s support for this explanation in the context of light - duty fuel economy decisions: a loss - averse consumer’s expected net present value of increasing the fuel economy of a passenger car can be very close to zero , even if a risk- neutral expected value calculation shows that its buyer can expect significant net benefits from purchasing a more fuel efficient car . 5 Supporting this hy pothesis is a finding b y Dasgupta et. al (2007) that consumers are more likely

to lease than buy

a vehicle with higher maintenance costs because it provides them with the option to retur n it before those costs become too high. 6 However, the agencies know of no studies that have estimated the impact of uncertainty on perceived future savings for medium - and heavy- duty vehicles . Purchasers’ uncertainty

about future fuel prices implies that mandating improvements in fuel efficiency

can reduce the expected utility associated with truck purchases. This is because adopting such regulation requires purchasers to assume a greater level of risk than they would in its absence, even if the future f uel savings predicted by

a risk - neutral calculation actually******* **E.O. 12866 Review –**  **Revised Version –**  **Do Not Cite, Quote, or Release During Review** *******

9 - 7 materialize. One commenter expressed support for this argument. Thus the mere existence of uncertainty about future savings in fuel costs does not by itself assure that regulations requiring improved fuel efficiency

will necessaril y provide economic benefits for truck purchasers and operators. On the other hand, because risk aversion reduces expected returns for businesses, competitive pressures can reduce risk aversion: risk- neutral companies can make higher average profits over time. Thus, significant risk aversion is unlikely to survive competitive pressures. 

### 9.2.5 **Adjustment and Transactions Costs** Another hypothesis is that transactions costs of changing to new technologies (how easily drivers w ill adapt to the changes, e.g.) may slow or prevent their adoption. Because of the diversity in the trucking industry , truck owners and fleets may like to see how a new technology works in the field, when applied to their specific operations, before they adopt it. One commenter expressed support for this argument. If a conservative approach to new technologies leads truck buye rs to adopt new technologies slowly , then successful new technologies are likel y to be adopted over time without market interventi on, but with potentially significant delays in achieving fuel saving, environment, and energy security benefits. In addition, there may

be costs associated with training drivers to realize the potential fuel savings enabled b y new technologies, or with acc elerating fleet operators’ scheduled fleet turnover and replacement to hasten their acquisition of vehicles equipped with new fuel - saving technologies. Here, again, there may be no market failure; requiring the widespread use of these technologies may

imp ose adjustment and transactions costs not included in this analy sis. As in the discussion of the role of risk, these adjustment and transactions costs are ty pically immediate and undiscounted, while their benefits are future and uncertain; risk or loss av ersion may further discourage companies from adopting new technologies. To the extent that there may be transactions costs associated with the new technologies, then regulation gives all new truck purchasers a level playing field, because it will require all of them to adjust on approximately the same time schedule. If experience with the new technologies serves to reduce uncertainty and risk, the industry as a whole may become more accepting of new technologies. This could increase demand for future new technologies and induce additional benefits in the legacy fleet through complementary efforts such as SmartWay . 

### 9.2.6 **Additional Hypotheses** In the public comments, two additional ideas were raised for the lack of adoption of what appears to be cost - effective fue l - saving technology . The first suggestion is that tighter diesel emissions standards caused fuel efficiency for diesel trucks to decline in the past decade. Because engine manufacturers would have to invest heavily (both financially

and with personnel) in emissions reduction technologies, they would not invest in fuel efficiency . The costs associated with the decline in fuel efficiency due to the emissions regulations were accounted for in that rulemaking. A second suggestion is that a truck may be a “positional good”

– that is, a good whose value depends on how it compares to the goods owned b y others. If trucks confer status on their owners or operators, and if that status depends on easily observable characteristics, then owners**Regulatory Impact Analysis**

9 - 8

may invest disproportionately in status - granting characteristics rather than less visible characteristics, such as fuel efficiency . Because status depends on comparisons to others, an “arms race” may

develop in which all parties spend additional money on visible characteristics but may not manage to make themselves better off. In this case, regulation may improve welfare: b y increasing the requirements for non - positional fuel efficiency , regulation could reduce expenditures made purel y for competition rather than actual inc rease in welfare. In a competitive business, cost reduction provides a major opportunity cost to investing in status rather than in fuel - saving technology ; thus, this argument may play less of a role in the heavyduty market than in the consumer market fo r vehicles. Both these hypotheses leave open the question, though, why additional investments were not made in fuel efficiency if they would provide rapid pay back. Truck purchasers should, in principle, be willing to buy additional fuel - saving technology as long as it is cost - effective, regardless of other vehicle attributes. Limited access to capital, if it is a problem in this sector, might provide some reason for the “crowding out” of the purchase of fuel - saving technology . The agencies received no evidence indicating that constrained access to capital might explain the efficiency gap in this market. 

### 9.2.7 **Summary** On the one hand, commercial vehicle operators are under competitive pressure to reduce operating costs, and thus their purchasers would be expec ted to pursue and rapidly adopt cost effective fuel - saving technologies. On the other hand, the short pay back period required b y buyers of new trucks is a sy mptom that suggests some combination of uncertainty about future cost savings, transactions costs, and imperfectly functioning markets. In addition, widespread use of tractor- trailer combinations introduces the possibility that owners of trailers may have weaker incentives than truck owners or operators to adopt fuel - saving technology f or their trailers. The market for medium - and heavy- duty trucks may face these problems, both in the new vehicle market and in the resale market. Provision of information about fuel - saving technologies through voluntary programs such as SmartWay will assist in the adoption of new cost - saving technologies, but diffusion of new technologies can still be obstructed. Those who are willing to experiment with new technologies expect to find cost savings, but those may be difficult to prove. As noted above, because individual results of new technologies vary , new truck purchasers may find it difficult to identify or verify the effects of fuel - saving technologies. Those who are risk- averse are likel y to avoid new technologies out of concerns over the possibility of inadequate returns on the investment, or with other adverse impacts. Competitive pressures in the freight transport industry can provide a strong incentive to reduce fuel consumption and improve environmental performance. However, not every driver or trucking fleet operating today has the requisite ability

or interest to access the technical information, some of which is already provided by SmartWay, nor the resources necessary to evaluate this information within the context of his or her own freight operation. It i s unclear, as discussed above, whether some or many of the technologies would be adopted in the absence of the program. To the extent that they would have been adopted, the costs and the benefits attributed to those technologies may not in fact be due to the program and may therefore be overstated. Both baselines used project substantially less adoption than the******* **E.O. 12866 Review –**  **Revised Version –**  **Do Not Cite, Quote, or Release During Review** *******

9 - 9 agencies consider to be cost - effective. The agencies will continue to explore reasons for this slow adoption of cost - effective technologies. 

### 9.3 **Re bound Effect**  The VMT rebound effect refers to the fraction of fuel savings expected to result from an increase in fuel efficiency that is offset by

additional vehicle use. If truck shipping costs decrease as a result of lower fuel costs, an increase in tr uck VMT may

occur. Unlike the light duty rebound effect, the heavy- duty (HD) rebound effect has not been extensively studied. Because the factors influencing the HD rebound effect are generally different from those affecting the light - duty rebound effect , much of the research on the light - duty sector is not likely to apply to the HD sectors. O ne of the major differences between the HD rebound effect and the light - duty rebound effect is that HD vehicles are used primarily for business purposes. Since the se businesses are profit driven, decision makers are highl y likely to be aware of the costs and benefits of different operating and shipping decisions, both in the near- term and long - term. Therefore, both truck operators and shippers are likely to take into account changes in the overall operating costs per mile when making operating and shipping decisions that affect truck usage . Another difference from the light - duty case is that, a s discussed in the recent NAS Report, when calculating the change in tr ucking costs that causes the rebound effect, all components of truck operating costs should be considered. The cost of labor and fuel generally constitute the two largest share s of truck operating costs , depending on the price of petroleum, distance trave led, type of truck, and commodity . 7 8 See Figure 9 - 1. In addition , the equipment depreciation costs associated with the purchase or leas e of the truck is also a significant component of total operating costs. Even though vehicle purchases are lump - sum co sts , they are likely to be considered as operating costs by trucking firms, and these costs are, in many cases, expected to be passed onto the final consumers of shipping services. By partially offsetting the reduction in fuel costs resulting from higher fuel efficiency , higher vehicle purchase or lease prices could thus help temper the magnitude of the fuel economy rebound effect relative to that for light - duty vehicles, in which vehicle depreciation costs may not be considered an operating cost by vehicl e owners . When calculating the net change in operating costs, both the increase in new vehicle costs and the decrease in fuel costs per mile should be taken into consideration. The higher the net cost savings, the higher the expected rebound effect. Conv ersel y, if the upfront vehicle costs outweighed future cost savings and total costs increased, shipping costs would rise, which would likely result in a decrease in truck VMT. In theory, other cost changes resulting from any requirement to achieve higher fuel economy, such as changes in maintenance costs or insurance rates , sh ould also be taken into account, although information on potential changes in these elements of truck operating cost s is extremel y limited.**Regulatory Impact Analysis**

According to the NAS study , it is “not possible to provide a confident measure of the rebound effect , ” yet NAS concluded that a rebound effect likely exists and that “estimates of fuel savings from regulatory standards will be somewhat misestimated if the rebound effe ct is not considered.” While we believe the HD rebound effect needs to be studied in more detail, we have attempted to capture the potential impact of the rebound effect in our anal ys is. For this rule , we have used a rebound effect for single unit trucks of 15 percent , a rebound effect for medium - duty (2b and 3) trucks of 10 percent , and a rebound effect for combination tractors of 5 percent . That is, we assume that for every 1 percent decrease in operating costs for trucks ($/mile), we anticipate a 0.15 percent , 0.10 percent , and 0.05 percent increase in VMT for single unit trucks, MD trucks, and combination tractors, respectivel y. For this rule, we do not discern between short - run and long - run rebound effects, although these effects may

differ, as discussed below. These VMT impacts are reflected in the estimates of total GHG and other air pollution reductions presented in Chapter 5 of the RIA .******* **E.O. 12866 Review –**  **Revised Version –**  **Do Not Cite, Quote, or Release During Review** *******

9 - 11 

### 9.3.1 **Factors Affecting the Magnitude of the Rebound Effect** The HD rebound effect is driven by the interaction of several different factors. In the short - run, decreasing the fuel cost per mile of operating trucks could lead to a decrease in delivered prices for product s shipped by truck . Lower delivered prices could stimulate additional demand for those products, which would then result in an increase in truck usage and VMT. In the long - run, shippers could reorganize their logistics and distribution networks to take advantage of lower truck shipping costs. For example, shippers may shift away

from other modes of s hipping such as rail, barge, or air. In addition, shippers may also choose to reduce the number of warehouses, reduce load rates, and make smaller, more frequent shipments, all of which could also lead to an increase in HD VMT. Finally , the benefits of the fuel savings could ripple through the economy , which could in turn increase overall demand for goods and services shipped by

trucks , and therefore increase HD VMT. Conversel y, if a fuel efficiency regulation leads to net increases in the cost of trucking because fuel savings do not fully offset the increase in upfront vehicle costs, then the price of trucking services could rise, spurring a decrease in HD VMT and a shift to alternative shipping modes . These effects would also ripple through the economy . As discussed in Section 8 of the preamble, the magnitude of the rebound effect is likely to be determined b y the extent of market failures that affect demand for fuel economy in HD fleets, such as split incentives and imperfect information, as well as ra tional firm responses to the tradeoff between higher certain upfront vehicle costs and lower but uncertain future expenditures on fuel. 

### 9.3.2 **Options for Quantifying the Rebound Effect**  As described in the previous section, the fuel economy rebound effect for h eavy- duty vehicles has not been studied as extensively as the rebound effect for light - duty vehicles, and virtually no research has been conducted on the medium - duty truck rebound effect. In this rule , we discuss four options for quantifying the rebound e ffect. 

### 9.3.2.1 **Aggregate Estimates** The aggregate approximation approach quantifies the overall change in truck VMT as a result of a percentage change in freight rates . It is important to note that most of the aggregate estimates measure the change in freight demanded (tons or ton - miles), rather than a change in fuel consumption or VMT. The change in ton s or ton - miles is more accurately characterized as a freight elasticity. Therefore, it may not be entirely appropriate to interpret these freight elasticities as measure s of the rebound effect, although these terms are sometimes used interchangeabl y in the literature. 9 Given these caveats, freight elasticity estimates rel y on estimates of aggregate price elasticity of demand for trucking services, given a perc entage change in trucking prices, which is generally referred to as an “own price elasticity .” Estimates of trucking own - price elasticities vary widely (from positive 1.72 to negative 7.92) , though a 2004 literature survey

found aggregate elasticity estim ates generall y fall in the range of - 0.5 to - 1.5 . 10 See Figure 9 - 2. In other words, given an own price elasticity of - 1.5, a 10 percent decrease in trucking prices leads to a 15 percent increase in truck shipping demand.**Regulatory Impact Analysis**

9 - 12

Another challenge of estimating the rebound effect using f reight elasticities is that these values appear to v ary substantially based on the demand elasticity measure (e.g., ton or ton mile), the model specification (e.g., linear functional form or log linear), the length of the trip , an d the ty pe of cargo. Ingeneral, elasticity estimates of longer trips tend to be larger than elasticity estimates for shorter trips. In addition, elasticities tend to be larger for lower- value commodities compared to higher - value commodities. Although these factors explain some of the differences in estimates , much of the observed variation cannot be explained quantitatively . For example, a recent study that controlled for these variables onl y accounted for about half of the observed variation . 11 An other important variable influencing freight elasticity estimates is whether potential mode shifting is taken into account. Although the total demand for freight transport is generally determined b y economic activity , there is often the choice of shipping freight on modes other than truck . This is because the United States has extensive rail, waterway and air transport networks in addition to an e xtensive highway network ; these networks often closel y paralle l each other and are often viable choices for freight transport for many long - distance routes within the continent. If rates go down for one mode, there will be an increase in demand for that mode and some demand will be shifted from other modes. This “cross - price elasticity” is a measure of the percentage change in demand for shipping b y another mode (e.g., rail) given a percentage change in the price of trucking. Aggregate estimates of cross - price elasticities also vary widel y, and there is no general consensus on the most appropriate value to use f or analy tical purposes. The NAS report cites values ranging from 0.35 to 0.59. 12 Other reports provide significantly different cross - price elasticities, ranging from 0.1 13 to 2.0 . 14******* **E.O. 12866 Review –**  **Revised Version –**  **Do Not Cite, Quote, or Release During Review** *******

When considering intermodal shift , one of the most relevant kinds of shipments are those that are competitive between rail and truck modes. These trip s generall y include long - haul shipments greater than 500 miles, which weigh between 50,000 and 80,000 pounds (the legal road limit in many

states). Special kinds of cargo like coal and short - haul deliveries are of less interest because they

are generall y not economically transferable between truck and rail modes, and they would not be expected to shift modes except under an extreme price change. However, the total amount of freight that could potentially be subject to mode shifting has also not been studi ed extensively . 

### 9.3.2.2 **Sector -**  **Specific Estimates** Given the limited data available regarding the HD rebound effect, the aggregate approach greatl y simplifies many of the assumptions associated with calculations of the rebound effect. In reality , however, respon ses to changes in fuel efficiency and new vehicle costs will vary significantl y based on the commodities affected. A detailed, sector specific approach, would be expected to more accurately reflect changes in the trucking market in response to the standards in this rule . For example, input - output tables could be used to determine the trucking cost share of the total delivered price of a commodity . Using the change in trucking prices described in the aggregate approach, the product - specific demand elastic ities could be used to calculate the change in sales and shipments for each product. The change in shipment increases could then be weighted b y the share of the trucking industry total, and then summed to get the total increase in trucking output. A simp lifying assumption could then be made that the increase in output results in an increase in VMT. To the best of our knowledge, this ty pe of detailed data has not yet been collected, therefore we were unable to use this methodology for estimating the rebound effect for this rule. 

### 9.3.2.3 **Econometric Estimates** Similar to the methodology used to estimate the light - duty rebound effect, the HD rebound effect could be modeled econometricall y by estimating truck demand as a function o f economic activity

(e.g., GDP) and different input prices (e.g., vehicle prices, driver wages, and fuel costs per mile). This ty pe of econometric model could be estimated for either truck VMT or ton - miles as a measure of demand. The resulting elasticity estimates could then be used to determine the change in trucking demand, given the change in fuel cost and truck prices per mile from these standards. One of the challenges associated with an econometric anal ys is is the potential for omitted variable bias, which could either overstate or understate the potential rebound effect if the omitted variable is correlated with the controlled variables. 

### 9.3.2.4 **Other Modeling Approach**  **es** Regulation of the heavy- duty vehicle industry has been studied in more detail in Europe, as the European Commission (E C) has considered allowing longer and heavier trucks for freight transport. Part of the analysis considered by the EC relies on country- specific modeling of changes in the freight sector that would result from changes in regulations. 15 This approach attempts to explicitly

calculate modal shift decisions and impacts on GHG emissions. Although similar ty pes of anal ys is have not been conducted extensively in the U.S., research is currently underway that explores the potential for intermodal shifting in the U .S. For example, Winebrake******* **E.O. 12866 Review –**  **Revised Version –**  **Do Not Cite, Quote, or Release During Review** *******

9 - 15 and Corbett have developed the Geospatial Intermodal Freight Transportation (GIFT) model, which evaluates the potential for GHG emissions reductions based on mode shifting, given existing limitations of infrastructure and other route characteristics in the U.S. 16 This model connects multiple road, rail, and waterway transportation networks and embeds activity- based calculations in the model. Within this intermodal network, the model assigns various economic, time - of - delivery , energy , and environmental attributes to real - world goods movement routes. The model can then calculate different network optimization scenarios, based on changes in prices and policies. 17 However, more work is needed in this area to determine whether this ty pe of methodology

is appropriate for the purposes of capturing the rebound effect. 

### 9.3.3 **Estimates of the Rebound Effect**  The aggregate methodology was used by

Cambridge S ys tematics, Inc. (CSI) to show several examples of the magnitude of the rebound effect. 18 Intheir paper commissioned by the NAS in support of the HD report, CSI calculated an effective rebound effect for two different technology

cost and fuel savings scenarios associated with an example Class 8 combination tractor . Scenario 1 increased average fuel economy from 5.59 mpg to 6.8 mpg, with an additional cost of $22,930. Scenario 2 increased the average fuel economy to 9.1 mpg, at an incremental cost of $71,630 per vehicle. Both of these scenarios were based on the technologies and targets fro m a recent Northeast States Center for a Clean Air Future (NESCCAF) and International Council on Clean Transportation (I CCT) report . 19 The CSIexamples provided estimates using a range of own price elasticities ( - 0.5 to - 1.5) and cross - price elasticities (0 .35 to 0.59) from the literature. For these calculations, CSIassumed 142,706 million miles of truck VMT and 1,852 billion ton - miles were affected. The truck VMT was based on the Bureau of Transportation Statistics (BTS) highway miles for combination tractors in 2006, and the rail ton miles were based on the 2006 BTS total railroad miles. This assumption may overstate the potential rebound effect, since not all highway miles and rail ton miles are in direct competition. However, this assumption appears to be reasonable in the absence of more detailed information on the percentage of total miles and ton - miles that are subject to potential mode shifting. For CSI’s calculations, all costs except fuel costs and vehicle costs were taken from the 2008 ATRI study . It is not clear from the report how the new vehicle costs were incorporated into the per mile operating costs calculations. For example, in both the ATRIreport and the CSI report, assumptions about depreciation , useful life, and the opportunity c ost of capital are not explicitly discussed. Based on these two scenarios, CSIfound a rebound effect of 11 - 31 percent for Scenario 1 and 5 - 16 percent for Scenario 2 when the fuel savings from reduced rail usage were not taken into account (“First reboun d effect”). When the fuel savings from reduced rail usage were included in the calculations, the overall rebound effect was between 9 - 13 percent for Scenario 1 and 3 - 15 p ercent for Scenario 2 (“Second Rebound Effect”). See Table 9 - 1 . CSIincluded a number of caveats associated with these calculations. Namely , the elasticity estimates derived from the literature are “heavil y reliant on factors including the type of demand measures analyzed (vehicle - miles of travel, ton - miles, or tons), geography , trip l engths, markets served, and commodities transported .” Furthermore, the CSIexample only focused on Class 8 trucks and did not attempt to quantify the potential rebound effect for any**Regulatory Impact Analysis**

9 - 16

other truck classes. Finally , these scenarios were characterized as “sk etches” and were not included in the final NAS report. In fact, the NAS report asserted that it is “not possible to provide a confident measure of the rebound effect”, yet concluded that a rebound effect likely exists and that “estimates of fuel savings f rom regulatory

standards will be somewhat misestimated if the rebound effect is not considered.” **Table 9**  **- 1**  **Range of Rebound Effect Estimates from Cambridge Systematics Aggregate Assessment**  Scenario 1 (6.8 mp g, $22,930) Scenario 2

(9.1 mpg, $71,630) “First Rebound Effect” (increase in truck VMT resulting from decrease in operating costs) 11 - 31% 5 - 16% “Second Rebound Effect” (net fuel savings when decreases from rail are taken into account) 9 - 13 % 3 - 15% As an alternative, using the econometric approach, NHTSA has estimated the rebound effect in the short - run and long run for single unit (Class 4 - 7) and combination (Class 8) trucks . As shown in Table 9 - 2 , the estimates for the long - run rebound effect are larg er than the estimates in the short run, which is consistent with the theory that shippers have more flexibility to change their behavior (e.g., restructure contracts or logistics) when they are given more time. In addition, the estimates derived from the national data also showed larger rebound effects compared to the state data. 20 One possible explanation for the difference in the estimates is that the national rebound estimates are capturing some of the impacts of changes in economic activity. Histori cally , large increases in fuel prices are highl y correlated with economic downturns, and there may not be enough variation in the national data to differentiate the impact of fuel price changes from changes in economic activity . In contrast, some states m ay see an increase in output when energy prices increase (e.g., large oil producing states such as Texas and Alaska), therefore the state data may

be more accurately

isolating the impact of fuel price changes from that of changes in economic activity . It is important to note that these estimates of the rebound effect reflect the partial effects of fuel prices and fuel economy changes on truck usage, but not the effect of truck prices. Therefore, these estimates do not take into account the partially offsetting impacts of increases in new vehicle costs that are likel y to result from regulations requiring higher fuel economy. For example, if the increase in new vehicle prices associated with increased fuel economy offset half of the resulting savings in fue l costs, then the effective rebound effect would be half of the value shown in Table 9 - 2.

9 - 17 As discussed throughout this section, there are multiple methodologies for quantifying the rebound effect, and these different methodologies produce a large range of potential values of the rebound effect. However, for the purposes of quantifying the rebound effect for this program , we have used a rebound effect with respect to changes in fuel costs per mile on the lower range of the long - run estimat es. Given the fact that the long - run state econometric estimates are generally

more consistent with the aggregate estimates, for this program we have chosen a rebound effect for vocational vehicles of 15 percent that is within the range of estimates from both methodologies. Similarly, we have chosen a rebound effect for combination tractors of 5 percent. To date, no estimates of the HD pickup truck and van ( Class 2b and 3) rebound effect have been cited in the literature. Since these vehicles are used for very different purposes than heavy- duty vehicles, it does not necessarily seem appropriate to apply one of the heavy- duty estimates to the HD pickup trucks and vans . These vehicles are more similar in use to large light - duty vehicles, so for the purp oses of our analy sis, we have chosen to apply the light - duty rebound effect of 10 percent used in the recent final rule establishing fuel economy and GHG standards for MYs 2012 - 2016 light - duty vehicles to this class of vehicles. 

### 9.3.4 **Application of the Rebou**  **nd Effect to**  **VMT Estimates** It should be noted that the NHTSA econometric analy sis attempts to isolate the rebound effect with respect to changes in the fuel cost per mile driven. As described previously , the rebound effect should be a measure of the chang e in VMT with respect to the change in overall operating costs. Therefore, NHTSA’s rebound estimates with respect to fuel costs per mile must be “scaled” to appl y to total op erating costs. For example, we assumed the elasticity of C lass 8 truck use with respect to fuel cost per mile driven is - 0.05 (which corresponds to a 5 percent fuel economy rebound effect), and that fuel costs average 4 5 percent of total truck operating costs ; therefore , the elasticity

of truck use with respect to total operating cost s is - 0.05/0.4 5 = - 0.11 . This calculation would correspond to an “overall” rebound effect value

– that is, a rebound effect with respect to total truck operating costs

– of - 11 percent . In other words, cutting fuel costs per mile by 10 percent would correspond to onl y a 4. 5 percent decline in total truck operating costs, so the elasticity

of truck use with respect to total operating costs would have to be 2.3 times (100%/4 5 %) larger than the elasticity of truck use with respect to fuel cost alone, in order to produce the same response in truck VMT (4 .5 %* - 0.11 = 10%* - 0.05). We conducted similar calculations for 2b/3 trucks assuming fuel costs are on average 2 1 percent of total operating costs, and for vocational vehicles assuming fuel costs are on average 2 5 percent of total operating costs. Furthermore, due to timing constraints we assumed an “average” incremental technology

cost including indirect costs, as shown in Table 9 - 3 , based on the estimates developed for the NPRM, which di ffer slightl y from the values included in RIA Chapter 7 .

9 - 18

For the purposes of this rulemaking , we made several additional simplifying assumptions when appl ying the overall rebound effect to each class of truck. For example , we assumed that per mile vehicle costs were based on the new vehicle cost (e.g., $100,000 for the reference case Class 8 combination tractor) divided b y the total lifetim e number of expected vehicle miles (e.g., 1.26 million miles for a Class 8 combination tractor , 288,000 miles for 2b/3 trucks, and 334,000 miles for vocational vehicles ). We recognize that this calculation implicitly assumes that truck depreciation is strictly

a function of usage , and that it does not take into account the opportunity cost of alternative uses of capital. As a result, the new vehicle cost per mile assumptions used in these calculations represent a smaller percentage of total operating cost s compared to the ATRI and CSIexamples. Furthermore, this assumption implies that the new vehicle buyer and the used vehicle buye r value fuel economy in the same way. Although anecdotal evidence suggests fuel efficiency

may not be taken into account in the used vehicle market , this phenomenon is not well understood and therefore not taken into account in this analy sis . Other simplifying assumptions include the use of an average cost rather than a marginal cost . Some shippers may use a marginal cost to determine whether to increase their fuel usage, however we do not have any data on when shippers might use a marginal cost calculation rather than an average cost calculation. Although using a marginal cost might be more appropriate for calculating the rebound effect, we do not have a methodology for calculating the marginal cost . 21 In the costs and benefits summarized in Chapter 9.5 , we have not taken into account any potential fuel savings or GHG emission reductions from the rail, air or water- borne shipping sector s due to mode shifting. However, we have provided CSI ’s example calculations in Table 9 - 1. The rebound effect values used in the cost and benefit anal ys is fall within the range of the “second rebound effect” identified in the CSIanaly sis , which does account for offsetting savings from reduced rail shipping . In addition, we have not attempted to capture how current market failures might impact the rebound effect. The direction and magnitude of the rebound effect in the HD truck market are expected to vary

depending on the existence and ty pes of market failures affecting the fuel economy of the trucking fleet. If firms are already accuratel y accounting for the costs and benefits of these technologies and fuel savings, then these regulatio ns would increase their net costs, because trucks would already include all cost - effective fuel saving technologies. As a result, the rebound effect would actuall y be negative and truck VMT would decrease as a result of these regulations. However, if firms are not optimizing their behavior today due to factors such as lack of reliable information (see p reamble Section VIII.A. for further discussion), it is more likely that truck VMT would increase. If firms recognize their lower net costs as a result of these regulations and pass those costs along to their customers, then the rebound effect would increase truck VMT. This response assumes that trucking rates include both truck purchase costs and fuel costs, and that the truck purchase costs included in the rates spread those costs over the full expected lifetime of the trucks. If those costs are spread over a shorter period, as the expected short pay back period implies, then those purchase costs will inhibit reduction of freight rates, and to the extent that they

do so the rebound effect will be proportionall y smaller. As discussed in more detail in p reamble Section VIII.A, if there are market failures such as split incentives, estimating the rebound effect may depend on the nature of the failures. For******* **E.O. 12866 Review –**  **Revised Version –**  **Do Not Cite, Quote, or Release During Review** *******

9 - 19 example, if the original purchaser cannot fully recoup the higher upfront costs through fuel savings before selling the vehicle nor pass those costs onto the resale buyer, the firm would be expected to raise shipping rates. A firm purchasing the truck sec ond - hand might lower shipping rates if the firm recognizes the cost savings after operating the vehicle, leading to an increase in VMT. Similarly, if there are split incentives and the vehicle buyer is n o t the same entity that purchases the fuel, than there would theoreticall y be a positive rebound effect. In this scenario, fuel savings would lower the net costs to the fuel purchaser, which would result in a larger increase in truck VMT. If all of these scenarios occur in the marketplace, the ir consequ ences for the rebound effect will depend on the extent and magnitude of their relative effects, which are also likel y to vary across truck classes (for instance, split incentives may be a much larger problem for C lass 7 and 8 combination tractor than they are for heavy- duty pickup trucks). 

### 9.4 **Monetized CO 2**  

### Impacts We assigned a dollar value to reductions in carbon dioxide (CO 2 ) emissions using recent estimates of the “social cost of carbon” (SCC). The SCC is an estimate of the monetized damages associated with an incremental increase in carbon emissions in a given year. Itis intended to include (but is not limited to) changes in net agricultural productivity, human health, property damages from increased flood risk, and the value of ecos ys tem services due to climate change. The SCC estimates used in this analy sis were developed through an interagency process that included EPA, DOT/NHTSA, and other executive branch entities, and concluded in February 2010. We first used these SCC estimates in the benefits anal ys is for the final joint EPA/DOT Rulemaking to establish Light - Duty Vehicle Greenhouse Gas Emission Standards and Corporate Average Fuel Economy Standards; see th at rulemaking ’s preamble for discussion about application of the SCC (75 FR 25324; 5/7/10 ). The SCC Technical Support Document (SCC TSD) provides a complete discussion of the methods used to develop these SCC estimates. 22 The interagency

group selected four SCC values for use in regulatory anal yses, which we have applied in this anal ysis: $ 5, $22, $36, and $6 7 per metric ton of CO 2 emissions in 2010, in 2009 dollars. 23 , 24 The first three values are based on the average SCC from three integrated assessment models, at discount rates of 5, 3, and 2.5 percent, respectively . SCCs at several disco unt rates are included because the literature shows that the SCC is quite sensitive to assumptions about the discount rate, and because no consensus exists on the appropriate rate to use in an intergenerational context. The fourth value is the 95th percentile of the SCC from all three models at a 3 percent discount rate. It is included to represent higher- than - expected impacts from temperature change further out in the tails of the SCC distribution. L ow probability , high impact events are incorporated into all of the SCC values through explicit consideration of their effects in two of the three models as well as the use of a probability density function for equilibrium climate sensitivity . Treating climate sensitivity probabilistically

results in more high temperature outcomes, which in turn lead to higher projections of damages. The SCC increases over time because future emissions are expected to produce larger incremental damages as physical and economic systems become more stressed in response to greater climatic change. Note that the interagency group estimated the growth rate of the SCC**Regulatory Impact Analysis**

9 - 20

directly using the three integrated assessment models rather than assuming a constant annual growth rate. This helps to ensure that the estimates are internally consist ent with other modeling assumptions. Table VIII.G.1 - 1 presents the SCC estimates used in this analysis. When attempting to assess the incremental economic impacts of carbon dioxide emissions, the analy st faces a number of serious challenges. A recent rep ort from the National Academies of Science (NRC 2009) points out that any assessment will suffer from uncertainty, speculation, and lack of information about (1) future emissions of greenhouse gases, (2) the effects of past and future emissions on the clim ate sy stem, (3) the impact of changes in climate on the physical and biological environment, and (4) the translation of these environmental impacts into economic damages. 25 As a result, any effort to quantify and monetize the harms associated with climate change will raise serious questions of science, economics, and ethics and should be viewed as provisional. The interagency

group noted a number of limitations to the SCC analysis, including the incomplete way

in which the integrated assessment models cap ture catastrophic and non catastrophic impacts, their incomplete treatment of adaptation and technological change, uncertainty in the extrapolation of damages to high temperatures, and assumptions regarding risk aversion. The limited amount of research linking climate impacts to economic damages makes the interagency

modeling exercise even more difficult. The interagency group hopes that over time researchers and modelers will work to fill these gaps and that the SCC estimates used for regulatory

anal ys is by

the Federal government will continue to evolve with improvements in modeling. Additional details on these limitations are discussed in the SCC TSD. In light of these limitations, the interagency group has committed to updating the current estimates as the science and economic understanding of climate change and its impacts on society improves over time. Specificall y, the interagency group has set a preliminary goal of revisiting the SCC values in the next few years or at such time as substantially updated models become available, and to continue to support research in this area. Applying the global SCC estimates, shown in Table 9 - 4 , to the estimated reductions in domestic CO 2 emissions for the final program, we estimate the dollar value of the climate related benefits for each anal ys is year. For internal consistency , the annual benefits are discounted back to net present value terms using the same discount rate as each SCC estimate (i.e. 5 percent , 3 percent , and 2.5 percent) rather than 3 percent and 7 percent . A The SCC estimates are presented in and the associated CO 2 benefit estimates for each calendar ye ar are shown in Table 9 - 5.

A It is possible that other benefits or costs of proposed regulations unrelated to CO 2 emissions will be discounted at rates that differ from those used to develop the SCC estimates.******* **E.O. 12866 Review –**  **Revised Version –**  **Do Not Cite, Quote, or Release During Review** *******

### 9.5 **Additional Impacts**  **9.5.1 Noise,**  **Congestion , and Accidents**  Section 9.2 discusses the likely sign of the rebound effect. If net operating costs of the vehicle decline, then we expect a positive rebound effect. Increased vehicle use associated with a positive rebound effect also contributes to increased traffic congestion, motor vehicle accidents, and highway

noise. Depending on how the additional trave l is distributed throughout the day and on where it takes place, additional vehicle use can contribute to traffic congestion and delay s by

increasing traffic volumes on facilities that are already heavily traveled during peak periods. These added delay s i mpose higher costs on drivers and other vehicle occupants in the form of increased travel time and operating expenses. Because drivers do not take these added costs into account in deciding when and where to travel, they must be accounted for separately a s a cost of the added driving associated with the rebound effect. Increased vehicle use due to a positive rebound effect may also increase the costs associated with traffic accidents. Drivers may take account of the potential costs they (and their passeng ers) face from the possibility of being involved in an accident when they decide to make additional trips. However, they probabl y do not consider all of the potential costs they impose on occupants of other vehicles and on pedestrians when accidents occur , so any increase in these “external” accident costs must be considered as another cost of additional rebound- effect driving. Like increased delay

costs, any

increase in external accident costs caused by added driving is likely to depend on the traffic co nditions under which it takes place, since accidents are more frequent in heavier traffic (although their severity may be reduced b y the slower speeds at which heavier traffic ty

pically moves). Finally , added vehicle use associated with a positive rebound effect may also increase traffic noise. Noise generated b y vehicles causes inconvenience, irritation, and potentially even discomfort to occupants of other vehicles, to pedestrians and other b ys tanders, and to residents or occupants of surrounding property. Because these effects are unlikely to be taken into account by the drivers whose vehicles contribute to traffic noise, they represent additional externalities associated with motor vehicle use. Although there is considerable uncertainty in measuring their value, any increase in the economic costs of traffic noise resulting from added vehicle use should be included together with other increased external costs from the rebound effect. EPA and NHTSA rel y on estimates of congestion, accident, and noise cos ts caused by pickup trucks and vans, single unit trucks, buses, and combination tractors developed b y the Federal Highway

Administration to estimate the increased external costs caused by added driving due to the rebound effect. 26 The FHWA estimates are intended to measure the increases in costs from added congestion, property damages and injuries in traffic accidents, and noise levels caused b y various classes of trucks that are borne b y persons other than their drivers (or “marginal” external costs). EPA and NHTSA employed estimates from this source previously in the anal ys is accompanying the light - duty 2012 - 2016 vehicle rulemaking . The agencies continue to find them appropriate for this anal ys is after reviewing the procedures used by FHWA to develop them and considering other available estimates of these values.**Regulatory Impact Analysis**

9 - 28

FHWA’s congestion cost estimates for trucks , which are weighted averages based on the estimated fractions of peak and off - peak freeway

travel for each class of trucks, already account for the f act that trucks make up a smaller fraction of peak period traffic on congested roads because they

try to avoid peak periods when possible. FHWA ’s congestion cost estimate s focus on freeway s because non - freeway effects are less serious due to lower traffic volumes and opportunities to re - route around the congestion. The agencies, however, applied the congestion cost to the overall VMT increase, though the fraction of VMT on each road ty pe used in MOVES range from 27 to 29 percent of the vehicle miles on freeway s for vocational vehicles and 53 percent for combination tractors . The results of this analy sis potentiall y overestimate the congestions costs associated with increased truck use, and thus lead to a conservative estimat e of benefits . EPA and NHTSA estimated the costs of additional vocational vehicle travel using a weighted average of 15 percent of the FHWA estimate for bus cost s and 85 percent of the FHWA estimate for single unit truck costs to reflect the make - up of this segment. The low, mid, and high cost estimates from FHWA updated to 200 9 dollars are included in Table 9 - 3 . **Table 9**  **- 10**  **Low -**  **Mid -**  **High Cost Estimates ( 2009**  **$/mile)**

used in the light - duty

2012 - 2016 vehicle rulemaking anal ys is. These costs are multiplied by

the annual increases in vehicle miles travelled from the rebound effect to yi eld the estimated increases in congestion, accident, and noise externality costs during each future ye ar. EPA and NHTSA use the aggregate per mile costs, as shown in Table 9 - 4 in 2009 dollars .

### 9.5.2 **Savings due to Reduced Refueling Time** Reducing the fuel consumptio n of heavy- duty trucks will either increase their driving range before they

require refueling , or lead truck manufacturers to offer, and truck purchasers to buy , smaller fuel tanks . Keeping the fuel tank the same size will allow truck operators to reduc e the frequency

with which drivers ty

picall y refuel their vehicles , by extending the upper limit o n the distance they

can travel before requiring refueling. Alternatively , if truck purchasers and manufacturers respond to improved fuel economy by reducing th e size of fuel tanks , the smaller tank will require less time to fill during each refueling stop . Because refueling time represents a time cost of truck operation, these time savings should be incorporated into truck purchasers’ decisions about how much fuel - saving technology they purchase as part of their choices of new vehicles. The savings calculated here thus raise the same questions discussed in p reamble VIII.A and RIA Section 9.1: does the apparent existence of these savings reflect failures in the market for fuel economy, or does it reflect costs that are not addressed in this analysis? The response to these questions could vary across truck segment. See those sections for further anal ys is of this question. No direct estimates of the value o f extended vehicle range or reduced fuel tank size are readil y available . Instead, this analysis calculate s the reduction in the annual amount of time a driver of each type of truck will spen d filling its fuel tank; this reduced time could result either f rom fewer refueling events, if new trucks’ fuel tank s stay the same size, or from less time spent filling the tank during each refueling stop , if new trucks’ fuel s tank are made proportionatel y smaller. As discussed in Section 9.2 in this RIA , the average number of miles each type of truck is driven annuall y will increase under the regulation, as truck operators respond to lower fuel costs (the “rebound effect”). The estimates of refueling time with the regulation in effect allow for this increase in truc k use. However, EPA’s estimate of the rebound effect does not account for any reduction in net operating costs from lower refueling time. Because the rebound effect should measure the change in VMT with respect to the net change in overall operating costs , refueling time costs would ideally factor into this calculation. The effect of this omission is expected to be minor because refueling time savings are small relative to the value of reduced fuel expenditures. The savings in refueling time are calculate d as the total amount of time the driver of a ty pical truck in each class will save each ye ar as a consequence of pumping less fuel into the vehicle ’s tank . The calculation does not include any reduction in time spent searching for a fuel ing station or other time spent at the station; it is assumed that time savings occur onl y when truck operators are actually refueling their vehicles . The calculation uses the reduced number of gallons consumed by truck type and divides that value b y the fuel dispense rate (shown in Tabl e 9 - 13 ) to determine the number of hours saved in a given ye ar. The calculation then applies DOT - recommended values of travel time savings to convert the resulting time savings to their economic value. The DOT - recommended value of travel time per vehicle - hour for truck drivers is $22. 36 in 2009 $ (converted from $ 18.10 in 2000$). 28 The inputs used in the anal ys is are included Tabl e 9 - 13 .

**9.6 The Effect**  **of Safety Standards and Voluntary Safety Improvements on Vehicle**  **Wei ght**  Safety standards developed by NHTSA in previous rulemakings may make compliance with the fuel efficiency

and CO 2 emissions standards more difficult or may reduce the projected benefits of the program. The primary way that safety

regulations can impact fuel efficiency and CO 2 emissions is through increased vehicle weight, which reduces the fuel efficiency (and thus increases the CO 2 emissions) of the vehicle. Using MY 2010 as a baseline, this section discusses the effects of other government regulation s on MY s 2014 - 2016 medium and heavy- duty vehicle fuel efficiency and CO 2 emissions . At this time, no known safety standards will affect new models in MY 2017 or 2018. NHTSA’s estimates are based on cost and weight tear- down studies of a few vehicles and c annot possibly cover all the variations in the manufacturers’ fleets. NHTSA also requested, and various manufacturers provided, confidential estimates of increases in weight resulting from safety improvements. Those increases are shown in subsequent tabl es. We have broken down our anal ys is of the impact of safety standards that might affect the MY s 2014 - 20 16 fleets into three parts: 1) those NHTSA final rules with known effective dates, 2) proposed rules or soon - to - be proposed rules b y NHTSA with or wi thout final effective dates, and 3) currentl y voluntary safety improvements planned b y the manufacturers. 

### 9.6.1 **Weight Impacts of Required Safety Standards** NHTSA has undertaken several rulemakings in which several standards would become effective for medium - and heavy- duty (MD/HD) vehicles between MY 2014 and MY 2016. We will examine the potential impact on MD/HD vehicle weights for MY s 2014 - 2016 using MY 2010 as a baseline.

1. FMVSS 119, Heav y Truck Tires Endurance and High Speed Tests 2. FMVSS 121, Air Brake Sy stems Stopping Distance 3. FMVSS 214, Motor Coach Lap/Shoulder Belts 4. MD/HD Vehicle Electronic Stability Control Sy stems 

### 9.6.1.1 **FMVSS 119, Heavy Truck Tires Endurance and High Speed Tests** NHTSA tentatively

determined that the FMVSS No. 119 performance tests develope d in 1973 should be updated to reflect the increased operational speeds and duration of truck tires in commercial service. A Notice of Proposed Rulemaking (NPRM) was issued December 7, 2010 (75 FR 60036). It proposed to increase significantly the stringen cy

of the endurance test and to add a new high speed test. The data in the large truck crash causation study (LTCCS) that preceded that NPRM found that J and Lload range tires were having proportionately more problems than the other sizes and the agency ’ s test results indicate that H, J , and Lload range tires are more likel y to fail the proposed requirements among the targeted F, G, H, J and L load range tires. 30 To address these problems, the H and J load range tires could potentially use improved rubber compounds, which would add no weight to the tires, to reduce heat retention and improve the durability of the tires. The L load range tires, in contrast, appear to need to use high tensile strength steel chords in the tire bead, carcass and belt areas, which would enable a weight reduction with no strength penalties. Thus , if the update to FMVSS No. 119 was******* **E.O. 12866 Review –**  **Revised Version –**  **Do Not Cite, Quote, or Release During Review** *******

9 - 33 finalized, we anticipate no change in weight for H and J load range tires and a small reduction in weight for L load range tires. This proposal could become a final rule with an effective date of MY 2016. 

### 9.6.1.2 **FMVSS No. 121, Airbrake Systems Stopping Distance** FMVSS No. 121 contains performance and equipment requirements for braking s ys tems on vehicles with air brake sy stems. The most recent major final rule affecting FMVSS No. 121 was published on July

27, 2009 , and became effective on November 24, 2009 (MY 2009). The final rule requires the vast majority of new heavy truck tractors (approximately 99 percent of the fleet) to achieve a 30 percent reducti on in stopping distance compared to currentl y required levels. Three - ax l e tractors with a gross vehicle weight rating (GVWR) of 59,600 pounds or less must meet the reduced stopping distance requirements by August 1, 2011 (MY 2011) , while two axle tractors and tractors with a GVWR above 59,600 pounds must meet the reduced stopping distance requirements b y the later date of August 1, 2013 (MY 2013). NHTSA determined that there are several brake s ystems that can meet the requirements established in the final rule , including installation of larger S - cam drum brakes or disc brake s ys tems at all positions, or hy brid disc and larger rear S - cam drum brake s ys tems. According to data provided by a manufacturer (Bendix) in response to the NPRM , the heaviest drum b rakes weigh more than the lightest disc brakes , while the heaviest disc brakes weigh more than the lightest drum brakes. For a three - axle tractor equipped with all disc brakes, then, the total weight could increase b y 212 pounds or could decrease b y 134 p ounds compared to an all - drum - braked tractor , depending on which disc or drum brakes are used for comparison. The improved brakes may add a small amount of weight to the affected vehicle s for MY s 2014 - 2016 , resulting in a slight increase in fuel consumpti on. 

### 9.6.1.3 **FMVSS No. 208, Motor coach Lap/Shoulder Belts** NHTSA is proposing lap/shoulder belts for all motorcoach seats. About 2,000 motorcoaches are sold per year in the United States. Based on preliminary results from the agency ’s cost/weight teardown studi es of motor coach seats, 31 NHTSA estimate s that the weight added b y 3 - point lap/shoulder belts ranges from 5.96 to 9.95 pounds per 2 - person seat. This is the weight only

of the seat belt assembly itself , and does not include changing the design of the seat , reinforcing the floor, walls or other areas of the motor coach. Few current production motor coaches have been installed with lap/shoulder belts on their seats, and the number of vehicles with these belts already installed could be negligible. Assuming a 54 passenger motor coach, the added weight for the 3 - point lap/shoulder belt assembl y would be in the range of 161 to 269 pounds (27 * (5.96 to 9.95)) per vehicle. This proposal could become a final rule with an effective date of MY 2016. 

### 9.6.2 **Electronic Stability Control Systems (ESC) for Medium**  **- and Heavy**  **- Duty**  **(MD/HD) Vehicles** The purpose of an ESC system for MD/HD vehicles is to reduce crashes caused by rollover or b y directional loss - of - control. ESC monitors a vehicle’s rollover threshold and lateral stability using vehicle speed, wheel speed, steering wheel angle, lateral acceleration, side slip**Regulatory Impact Analysis**

9 - 34

and yaw rate data and upon sensing an impending rollover or loss of directional control situation automatically

reduces engine throttle and applies braking fo rces to individual wheels or sets of wheel to slow the vehicle down and regain directional control. ESC is not currentl y required in MD/HD vehicles , but could be proposed to be required in the se vehicles by NHTSA. FMVSS No. 105, Hydraulic and electric brake s ys tems, requires multipurpose passenger vehicles, trucks and buses with a GVWR greater than 4,536 kg (10,000 pounds) to be equipped with an antilock brake s ys tem (ABS). All MD/HD vehicles hav ing a GVWR of more than 10,000 pounds, are required to have ABS installed by that standard. In addition to the existing ABS functionality, ESC requires sensors including a yaw rate sensor, lateral acceleration sensor, steering angle sensor and brake pressure sensor along with a brake solenoid valve. According to data provided by Meritor WABCO, the weight of an ESC sy stem for the model 4S4M tractor is estimated to be around 55. 5 pounds, and the weight of the ABS only is estimated to be 45.5 pounds. Thus, we estimate the added weight for the ESC for the vehicle to be 10 (55. 5

– 45.5) pounds. 

### 9.6.3 **Summary –**  **Overview of Anticipated Weight Increases** Table 9 - 16 s ummarizes estimates made by NHTSA regarding the weight added by the above discussed standards or likely rulemakings. NHTSA estimates that weight additions required b y final rules and likely NHTSA regulations effective in MY 2016 compared to the MY 2010 fleet will increase motor coach vehicle weight b y 171 - 279 pounds and will increase other heavy- duty truck weights by 10 pounds. **Table 9**  **- 16**  **: Weight Additions Due to Final Rules or Likely NHTSA Regulations: Comparing MY 2016 to the**  **MY 2010 Baseline Fleet** Standard Number Added Weight in pounds MD/HD Vehicle Added Weight in kilograms MD/HD Vehicle 119 0 0 121 0 a 0 a 208 Motor coaches only 161 - 269 73 - 122 MD/HD Vehicle Electronic Stability Control Sy stems 10 4.5 Total Motor coaches 171 - 279 77.5 - 126.5 Total All other MD/HD vehicles 10 4.5 Note: NHTSA’s final rule on Air Brakes, docket NHTSA - 2009 - 0083, dated July 2 7, 2009, concluded that a small amount of weight would be added to the brake systems but a weight value was not provided . 

### 9.6.4 **Effects of Vehicle Mass Reduction on Safety**  NHTSA and EPA have been considering the effect of vehicle weight on vehicle safety for the past several years in the context of our joint rulemaking for light - duty vehicle CAFE and******* **E.O. 12866 Review –**  **Revised Version –**  **Do Not Cite, Quote, or Release During Review** *******

9 - 35 GHG standards, consistent with NHTSA’s long - standing consideration of safety effects in setting CAFE standards. Combining all modes of impact, the latest anal ys is b y NHTSA for the MYs 2012 - 2016 final rule 32 found that reducing the weight of the heavier light trucks (LT > 3,870) had a positive overall effect on safety , reducing societal fatalities. In the context of the current rulemaking for HD fuel consumption and GHG standards, one would expect that reducing the weight of medium - duty trucks similarl y would, if anything, have a positive impact on safety. However, given the large difference in weight between light duty vehicles and medium - duty trucks, and even larger difference between light - duty vehicles and heavy- duty vehicles with loads, the agencies believe that the impact of weight reductions of medium - and heavy- duty trucks would not have a noticeable impact on safety for any of these classes of vehicles. Howev er, the agencies recognize that it is important to conduct further study and research into the interaction of mass, size and safety to assist future rulemakings, and we expect that the collaborative interagency work currentl y on - going to address this issue for the light - duty vehicle context may

also be able to inform our evaluation of safety effects for the final HD vehicle rule. We intend to continue monitoring this issue going forward, and may take steps in a future rulemaking if it appears that the MD/HD fuel efficiency and GHG standards have unforeseen safety consequences. The American Chemistry Council stated in comments to the agencies that plastics and plastic composite materials provide a new way to lighten vehicles while maintaining passenger safety. They

added that properties of plastics including strength to weight ratio, energy absorption, and flexible design make these materials well suited for the manufacture of medium - and heavy- duty vehicles. They submitted supporting analyses with their co mments. The National School Transportation Association stated that added structural integrity requirements increase weight of school buses, and thus decrease fuel economy . They asked that if there are safety and fuel economy trade - offs manufacturers sho uld be able to receive a waiver from the regulation requirements. Since no weight reduction is required for school buses

– or any other vocational vehicle

– the agencies do not believe this is an issue with the current regulation. 

### 9.7 **Petroleum ,**  **Energy and Na**  **tional Security impact**  **9.7.1** 

### Security **Impacts** Th e HD National Program is designed to reduce fuel consumption and GHG emissions in medium - and heavy- duty (HD) vehicles, which will result in improved fuel efficiency and , in turn, help to reduce U.S. petroleum imp orts. A reduction of U.S. petroleum imports reduces both financial and strategic risks caused b y potential sudden disruptions in the supply of imported petroleum to the U.S. This reduction in risk is a measure of improved U.S. energy security. This section summarizes the agencies’ estimates of U.S. oil import reductions and energy security benefits of the final HD National Program . Additional discussion of this issue can be found in Chapter VIII of the preamble. The agencies recognize that potential national and energy security risks exist due to the possibility

of tension over oil supplies. Much of the world’s oil and gas supplies are located in countries facing social, economic, and demographic challenges , thus making them even more**Regulatory Impact Analysis**

vulnerable to potential local instability . For example, in 2010 just over 40 percent of world oil supply came from OPEC nations, and this share is not expected to decline in the AEO 2011 projections through 203 0. Approximately 28 percent of global suppl y is from Persian Gul f countries alone. As another measure of concentration, of the 137 countries/principalities that export either crude oil or refined petroleum product, the top 12 have recently accounted for over 55 percent of exports. B Eight of these countries are member s of OPEC, and a 9 th is Russia. C Ina market where even a 1 - 2 percent suppl y loss raises prices noticeably , and where a 10 percent supply loss could lead to a significant price shock, this regional concentration is of concern. ” Historically , the countrie s of the Middl e East have been the source of eight of the ten major world oil disruptions 33 , with the 9 th originating in Venezuela, an OPEC member. Because of U.S. dependence on oil, the military could be called on to protect energy resources through such measures as securing shipping lanes from foreign oil fields. To maintain such military

effectiveness and flexibility, the Department of Defense identified in the Quadrennial Defense Review that it is “increasing its use of renewable energy supplies and re ducing energy

demand to improve operational effectiveness, reduce greenhouse gas emissions in support of U.S. climate change initiatives, and protect the Department from energy price fluctuations.” 34 The Department of the Navy has also stated that the Navy and Marine Corps rely far too much on petroleum, which “degrades the strategic position of our country and the tactical performance of our forces. The global supply of oil is finite, it is becoming increasingl y difficult to find and exploit, and over time cost continues to rise .” D In remarks given to the White House Energy

Security Summit on April 26, 2011, Deputy Security of Defense William J. Lynn, III noted the direct impact of energy security on military

readiness and flexibility . According to Deputy

Security Ly nn, “ Today , energy

technology

remains a critical element of our military

superiority . Addressing energy needs must be a fundamental part of our military planning.” E Thus, to the degree to which the final rule reduces reliance upon importe d energy supplies or promotes the development of technologies that can be deployed by either consumers or the nation’s defense forces, the United States could expect benefits related to national security, reduced energy

costs, and increased energy supply . The s e benefit s are why President Obama has identified this rule as a key component for improving energy efficiency

and putting America on a path to reducing oil imports in the Blueprint for a Secure Energy Future. F Although the agencies recognize that there clearl y is a benefit to the United States from reducing dependence on foreign oil, the agencies have been unable to calculate the monetary benefit that the United States will receive from the improvements in national security expected to

9 - 37 result from thi s rule. In contrast, the other portion of the energy security premium, the U.S. macroeconomic disruption and adjustment cost that arises from U.S. petroleum imports is included in the energy

security benefits estimated for this program. To summarize, the agencies have included onl y the macroeconomic disruption portion of the energy security benefits to estimate the monetary

value of the total energy

security benefits of this program. The agencies have calculated energy

security in very specific terms, as the reduction of both financial and strategic risks caused b y potential sudden disruptions in the supply of imported petroleum to the U.S. Reducing the amount of oil imported reduces those risks, and thus increases the nation’s energy security. **9.7.2 Impact o**  **n U.S. P**  **etroleum I**  **mports** In 200 8 , U.S. petroleum import expenditures represented 21 percent of total U.S. imports of all goods and services. G In200 8 , the United States imported 66 percent of the petroleum it consumed , and the transportation sector accounted for 70 percent of total U.S. petroleum consumption . This compares roughl y to 3 7 percent of petroleum from imports and 55 percent consumption of petroleum in the transportation sector in 1975. H Itis clear that petroleum imports have a significant imp act on the U.S. economy . Requiring lower GHG - emitting heavyduty vehicles and improved fuel economy in the U.S. is expected to lower U.S. petroleum imports. EPA used the MOVES model to estimate the reduced consumption in fuel due to this rule. A detaile d explanation of the MOVES model can be found in Chapter 5 o f this RIA. Based on a detailed anal ys is of differences in fuel consumption, petroleum imports, and imports of refined petroleum products and crude oil among the Reference Case, High Economic Gro wth, and L ow Economic Growth Scenarios presented in AEO 2011 , NHTSA and EPA estimate that approximately

50 percent of the reduction in fuel consumption resulting from adopting improved fuel GHG standards and fuel economy standards is likely to be reflected in reduced U.S. imports of refined fuel, while the remaining 50 percent would be expected to be reflected in reduced domestic fuel refining . Of this latter figure, 90 percent is anticipated to reduce U.S. imports of crude petroleum for use as a refinery feedstock, while the remaining 10 percent is expected to reduce U.S. domestic production of crude petroleum. Thus , on balance, each gallon of fuel saved as a consequence of improved fuel heavy- duty GHG standards and fuel economy standards is anticipated t o reduce total U.S. imports of crude petroleum or refined fuel by 0.95 gallons. I Based upon the fuel savings estimated b y the MOVES model and the 95 percent oil import factor, the reduction in U.S. oil imports from this rule are estimated for the years 2 020, 2030, 2040, and 2050 (in millions of barrels per day (MMBD)) in Table 9 - 17 below.

security is broadly defined as protecting the U.S. economy against circumstances that result in significant short - and long - term increases in energy costs. Most discussion of U.S. energy security revolves around the topic of the economic costs of U.S. dependence on oil imports. The U.S.’s energy security problem is that the U.S. relies o n imported oil from potentially unstable sources. In addition, oil exporters have the ability to raise the price of oil b y exerting monopol y power through the formation of a cartel, the Organization of Petroleum Exporting Countries (OPEC). Finally , these factors contribute to the vulnerability of the U.S. economy to episodic oil supply shocks and price spikes. In 2008, U.S. net expenditures for imports of crude oil and petroleum products were $326 billion (in 2007$, see Figure 9 - 3).

One effe ct of the HD National Program is that it promotes more efficient use of transportation fuels in the U.S . The result is that it reduces U.S. oil imports, which reduces both financial and strategic ris ks associated with a potential disruption in supply or a spike in the cost of a particular energy

source. This reduction in risks is a measure of improved U.S. energy security. For this rule, an “oil premium” approach is utilized to identify those energy security related impacts which are not reflected in the market price of oil, and which are expected to change in response to an incremental change in the level of U.S. oil imports.

import reductions developed in a 1997 ORNL Report by L eib y, Paul N., Donald W. Jones, T. Randall Curlee, and Russell L ee, entitled “ Oil Imp orts: An Assessment of Benefits and Costs. ” M When conducting this analysis, OR NL considered the full cost of importing petroleum into the U.S. The f

ull economic cost is defined to include two components in addition to the purchase price of petroleum itsel f. These are: (1) the higher costs for oil imports resulting from the effect of U.S. import demand on the world oil price and on OPEC market power ( i.e. , the “ demand” or “monopsony” costs); and (2) the risk of reductions in U.S. economic output and disrup tion to the U.S. economy caused b y sudden disruptions in the supply of imported oil to the U.S. ( i.e. , macroeconomic disruption/adjustment costs). Maintaining a U.S. military presence to help secure stable oil supply from potentiall y vulnerable regions of the world was not included in this analy sis because its attribution to particular missions or activities is difficult (as discussed further below). The literature on the energy security for the last two decades has routinel y combined the monopsony

and the macroeconomic disruption components when calculating the total value of the energy

security premium. However, in the context of using a global value for the Social Cost of Carbon (SCC) the question arises: h ow should the energy security premium be used when some benefits from the rule, such as the benefits of reducing greenhouse gas emissions, are calculated using a global value? Monopsony benefits represent avoided pay ments by the U.S. to oil producers in foreign countries that result from a decrease in the world oil price as the U.S. decreases its consumption of imported oil. Although there is clearl y a benefit to the U.S. when considered from a domestic perspective, the decrease in price due to decreased demand in the U.S. also represents a loss to other countries. Given the redistributive nature of this monopsony effect from a global perspective, it is excluded in the energy

security benefits calculations for this program. In contrast, the other portion of the energy

security premium, the U.S. macroeconomic disruption and adjustment cost that arises from U.S. petroleum imports, does not have offsetting impacts outside of the U.S., and, thus, is included in the energy security benefits estimated for this program. To summarize , the agencies have in cluded only the macroeconomic disruption portion of the energy security benefits to estimate the monetary value of the total energy

security benefits of this program . S ection VIII.I of the preamble contains more discussion of how the monopsony and macroec onomic disruption/adjustment components are treated for this analysis. As part of the process for developing the ORNL energy security estimates, EPA sponsored an independent , expert peer review of th e 2008 ORNL study . A report compiling the peer reviewers’ comments is provided in the docket. N Inaddition, EPA worked with ORNLto address comments raised in the peer review and to develop estimates of the energy security benefits associated with a reduction in U.S. oil imports. In response to peer reviewer comments, ORNLmodified its model by changing several key

parameters involving OPEC supply behavior,

9 - 41 the responsiveness of oil demand and suppl y to a change in the world oil price, and the responsiveness of U.S. economic output to a change in the world o il price. For this rulemaking , ORNLfurther updated the energy security premium by incorporating the most recent oil price forecast and energy market trends from the AEO 2011 (Earl y Release) into its model. In order for the energy security premium to be u sed in EPA’s MOVES model, ORNLdeveloped energy security premium estimates for a number of different ye ars ( i.e., 2020, 2030, and 2035 ) , Table 19 - 9 provides estimates for energy security premium for the ye ars 2020, 2030 and 2035, O as well as a breakdown of the components of the energy security premium for each year. The components of the energy security premium and their values are discussed below.

**9.7.3.2 Effect of Oil Use on**  **the Long**  **- Run Oil Price**  The first component of the full economic costs of importing petroleum into the U.S. follows from the effect of U.S. import demand on the world oil price over the long - run. B ecause the U.S. is a sufficientl y large purchaser of foreign oil supplies , its purchases can affect the world oil price. This monopsony power means that increases in U.S. petroleum demand can caus e the world price of crude oil to rise, and conversel y , that reduced U.S. petroleum demand can reduce the world price of crude oil. Thus , one benefit of decreasing U.S. oil purchases , due to the increased availability

and use of other transportation fuels , is the potential decrease in the crude oil price paid for all crude oil purchased. The demand or monopsony effect can be readily

illustrated with an example. If the U.S. imports 10 million barrels per day at a world oil price of $50 per barrel, its total daily bill for oil

O AEO 2011 forecasts energy market trends and values only to 2035. Th e post - 2035 energy security premium values are assumed to be equal to the 2035 estimate.**Regulatory Impact Analysis**

9 - 42

imports is $500 million. If a decrease in U.S. imports to 9 million barrels per day causes the world oil price to drop to $49 per barrel, the dail y U.S. oil import bill drops to $441 million (9 million barrels times $49 per barrel). While the world oil price only declines $1, the resulting decrease in oil purchase pay ments of $59 million per day ($500 million minus $441 million) is equivalent to an incremental benefit of $59 per barrel of oil imports reduced, or $10 more than the newl y- decreased world price of $49 per barrel. This additional $10 per barrel “import cost premium” represents the incremental external benefits to the U.S. for avoided import costs beyond the price paid oil purchases. This additional benefit arises only to the extent that reduction in U.S. oil imports affects the world oil price. ORNL estimates this component of the energy security benefit in 2020 to be $1 1.29 /barrel, with a range of $ 3.86 /barrel to $ 21.32 /barrel of imported oil reduced. It is important to no te that the decrease in global petroleum prices resulting from this rulemaking could spur increased consumption of petroleum in other sectors and countries, leading to a modest uptick in GHG emissions outside of the United States. This increase in global fuel consumption could offset some portion of the GHG reduction benefits associated with the rule. The agencies have not quantified this increase in global GHG emissions in the RIA. 

### 9.7.4 **Macroeconomic Disruption Adjustment Costs** The second component of the oil import premium, “macroeconomic disruption/adjustment costs ,” arises from the effect of oil imports on the expected cost of disruptions. A sudden increase in oil prices triggered b y a disruption in world oil supplies has two main effects: (1) it increa ses the costs of oil imports in the short - run and (2) it can lead to macroeconomic contraction, dislocation and Gross Domestic Product (GDP) losses. ORNL estimates the composite estimate of these two factors that comprise the macroeconomic disruption/adju stment costs premium to be $7. 11 /barrel in 2020, with a range of $ 3.50 /barrel to $ 11.40 /barrel of imported oil reduced. There are two main effects of macroeconomic disruption/adjustment costs. The first is the short - run price increase from an oil shock. The oil price shock results in a combination of real resource shortages, costly short - run shifts in energy supply , behavioral and demand adjustments by

energy users, and other response costs. Unlike pure transfers, the root cause of the disruption price increase is a real resource supply reduction due, for example, to disaster or war. Regions where supplies are disrupted, such as the U.S., suffer very high costs. Businesses’ and households’ emergency responses to suppl y disruptions and rapid price increa ses consume real economic resources. While households and businesses can reduce their petroleum consumption, invest in fuel switching technologies, or use futures markets to insulate themselves in advance against the potential costs of rapid increases in oil prices, when deciding how extensively to do so, they

are unlikely to account for the effect of their petroleum consumption on the magnitude of costs that supply interruptions and accompanying price shocks impose on others. As a consequence, the U.S. e conomy

as a whole will not make sufficient use of these mechanisms to insulate itself from the real costs of rapid increases in energy prices and outlays that usuall y accompany oil supply interruptions. Th erefore, the ORNLestimate of macroeconomic disrup tion/adjustment costs that******* **E.O. 12866 Review –**  **Revised Version –**  **Do Not Cite, Quote, or Release During Review** *******

9 - 43 the agencies use to value energy security benefits includes the increased oil import costs stemming from oil price shocks that are unanticipated and not internalized by advance actions of U.S. consumers. The second main effect of macroeconomic disruption/adjustment costs is the macroeconomic losses during price shocks that reflect both aggregate output losses and “allocative” losses. The former are a reduction in the level of output that the U.S. economy can produce full y using i ts available resources; and the latter stem from temporary dislocation and underutilization of available resources due to the shock, such as labor unemploy ment and idle plant capacity . The aggregate output effect, a reduction in “potential” economic output, will last so long as the price is elevated. It depends on the extent and duration of any disruption in the world supply

of oil, since these factors determine the magnitude of the resulting increase in prices for petroleum products, as well as whether and how rapidl y these prices return to their pre disruption levels. In addition to the aggregate contraction, there are “allocative” or “adjustment” costs associated with dislocated energy markets. Because supply disruptions and resulting price increases o ccur suddenl y, empirical evidence shows they also impose additional costs on businesses and households which must adjust their use of petroleum and other productive factors more rapidl y than if the same price increase had occurred gradually. Dislocational effects include the unemplo ym ent of workers and other resources during the time needed for their intersectoral or interregional reallocation, and pauses in capital investment due to uncertainty. These adjustments temporaril y reduce the level of economic output that can be achieved even below the “potential” output level that would ultimately be reached once the economy’s adaptation to higher petroleum prices is complete. The additional costs imposed on businesses and households for making these adjustments reflect their limited ability to adjust prices, output levels, and their use of energy , labor and other inputs quickly and smoothly in response to rapid changes in prices for petroleum products. Since future disruptions in foreign oil supplies are an uncertain prospect, each of the disruption cost components must be weighted b y the probability that the supply

of petroleum to the U.S. will actually

be disrupted. Thus, the “expected value” of these costs

– the product of the probability

that a suppl y disr

uption will occur and the sum of costs from reduced economic output and the economy’ s abrupt adjustment to sharply higher petroleum prices

– is the relevant measure of their magnitude. Further, when assessing the energy security value of a policy to reduc e oil use, it is only

the change in the expected costs of disruption that results from the policy that is relevant. The expected costs of disruption may change from lowering the normal (i.e., pre - disruption) level of domestic petroleum use and imports, from any induced alteration in the likelihood or size of disruption, or from altering the short - run flexibility (e.g., elasticity) of petroleum use. In summary , the steps needed to calculate the disruption or security premium are: 1) determine the likelihood of an oil supply disruption in the future; 2) assess the likely impacts of a potential oil supply

disruption on the world oil price; 3) assess the impact of the oil price shock on the U.S. economy (in terms of import costs and macroeconomic losses); and 4 ) determine how these costs change with oil imports. The value of price spike costs avoided by reducing oil imports becomes the oil security portion of the premium.**Regulatory Impact Analysis**

9 - 44

**9.7.4.1.1 Cost of Existing U.S. Energy Security Policies**  The last often - identified component of the full economic costs of U.S. oil import s are the costs to the U.S. taxpayers of existing U.S. energy security policies. The two primary examples are maintaining the Strategic Petroleum Reserve (SPR) and maintaining a military presence to help secure a stab le oil supply from potentiall y vulnerable regions of the world. The SPR is the largest stockpile of government - owned emergency crude oil in the world. Established in the aftermath of the 1973 - 74 oil embargo, the SPR provid es the U.S. with a response opti on should a disruption in commercial oil supplies threaten the U.S. eco nomy . It also allows the U.S. to meet part of its International Energy Agency obligation to maintain emergency oil stocks, and it provides a national defense fuel reserve. While the c osts for building and maintaining the SPR are more clearl y related to U.S. oil use and imports , historically these costs have not varied in response to changes in U.S. oil import levels. Thus, while SPR is factored into the ORNL anal ys is, the cost of maintaining the SPR is excluded. U.S. military

costs are excluded from the anal ys is performed b y ORNL because their attribution to particular missions or activities is difficult. Most military forces serve a broad range of security and foreign policy objectiv es. Attempts to attribute some share of U.S. military costs to oil imports are further challenged b y the need to estimate how those costs might vary with incremental variations in U.S. oil imports. 

### 9.7.4.2 **Energy S**  **ecurity B**  **enefits of this Program**  Using the same methodology as the peer- reviewed model, but updating the anal ys is using AEO 2011 world oil price values and the estimated fuel savings from the rule using the MOVES model, EPA has calculated the energy security benefits of the rule for the years 2020, 203 0, 2040, and 2050 P . Since the Agency is taking a global perspective with respect to valuing greenhouse gas benefits from the rule, onl y the macroeconomic adjustment/disruption portion of the energy

security premium is used in the energy security benefits estimates present below. These results are shown below in Table 9 - 20. **Table 9**  **- 20**  **U.S. Energy Security Benefits of the Heavy -**  **Duty Vehicle Rulemaking**  **in 2020, 203 0,**  **2040 and**  **2050 (in m** **illions of 2009$)** YEAR BENEFITS 2020 $499 2030 $1,132 2040 $1,477 2050 $1,710

P In order to determine the energy security benefits for beyond 2035, world oil prices were extrapolated from an average grow

th rate for the years 2017 to 2035. This is shown in the spreadsheet labeled "AEO2011 Price Projects_with_final_release.xlsx", which is in the Docket for this rule.******* **E.O. 12866 Review –**  **Revised Version –**  **Do Not Cite, Quote, or Release During Review** *******

### 9.8 **Summary of Benefits and Costs** In this section, the agencies present a summary of technology costs, fuel savings, benefits, and net benefits of the pro gram . Table 9 - 21 sho ws the estimated annual monetized costs of the program for the indicated calendar years. The table also shows the net present values of those costs for the calendar years 2012 - 2050 using both 3 percent and 7 percent discount rate s . Q Table 9 - 22 shows the estimated annual monetized fuel savings of the final program. The table also shows the net present values of those fuel savings for the same calendar ye ars using both 3 percent and 7 percent discount rates. In this table, the aggregat e value of fuel savings is calculated using pre - tax fuel prices since savings in fuel taxes do not represent a reduction in the value of economic resources utilized in producing and consuming fuel. Note that fuel savings shown here result from reductions in fleet - wide fuel use. Thus , they grow over time as an increasing fraction of the fleet meets the 2018 standards .

As discussed in Section 8.5, there are some limitations to the SCC analy sis, including the incomplete way in which the integrated assessment models capture catastrophic and non - catastrophic impacts, their incomplete treatment of adaptation and technological change, uncertainty in the extrapolation of damages to high temperatures, and assumptions regarding risk aversion.

Inaddition, these monetized GHG benefits exclude the value of reductions in non - CO 2 GHG emissions (C H 4 , N 2 O , HFC ) expected under this program . Although EPA has not monetized the benefits of reductions in non - CO 2 GHGs, the value of these reductions should not be interpreted as zero. Rather, the net reductions in non - CO 2 GHGs will contribute to this rule ’s climate benefits, as explained in Section III.F of the preamble .

The same discount rate used to discount the value of damages from future emissions (SCC at 5, 3, 2.5 percent) is used to calculate net present value of SCC for internal consistency. Refer to the SCC TSD for more detail. b Section 8.5 of the RIA notes that SCC increases over time. Corresponding to the years in this table (2020 - 2050) , the SCC estimates range as follows: for Average SCC at 5%: $ 7 - $16; for Average SCC at 3%: $ 2 7 - $46 ; f or Average SCC at 2.5%: $ 43 - $ 67 ; and for 95 th percentile SCC at 3%: $ 83 - $1 40 . Section VIII.F also presents these SCC estimates. c Note that “B” indicates unquantified criteria pollutant benefits in the year 2020. For the analysis of the final program, we only modeled the rule’s PM 2.5 - and ozone - related im pacts in the calendar year 2030. For the purposes of estimating a stream of future - year criteria pollutant benefits, we assume that the benefits out to 2050 are equal to, and no less than, those modeled in 2030 as reflected by the stream of estimated future emission reductions. The NPV of criteria pollutant - related benefits should therefore be considered a conservative estimate of the potential benefits associated with the final program. d Non - GHG - related health and welfare impacts (related to PM 2.5 and o zone exposure) range between $110 and $340 million in 2030, 2040, and 2050. $200 was chosen as the mid -point of this range for the purposes of estimating total benefits across all monetized categories. e The monetized GHG benefits presented in this analys is exclude the value of changes in non - CO 2 GHG emissions expected under this program (see RIA Chapter 5) . Although EPA has not monetized changes in non - CO 2 GHGs, the value of any increases or reductions should not be interpreted as zero. f Negative sign r epresents an increase in Accidents, Noise, and Congestion.

### 9.9 **Employment Impacts**  **9.9.1 Introduction**  Although analysis of employ ment impacts is n ot part of a cost - benefit analy sis (except to the extent that labor costs contribute to costs), employ ment impacts of federal rules are of particular concern in the current economic climate of sizeable unemploy ment. The recently issued Executive Order 135 63, “Improving Regulation and Regulatory Review” (January

18, 2011), states, “ Our regulatory s ys tem must protect public health, welfare, safety, and our environment while promoting economic growth, innovation, competitiveness, and job creation ” (emphasis added). Although EPA and NHTSA did not undertake an employ ment anal ys is of the******* **E.O. 12866 Review –**  **Revised Version –**  **Do Not Cite, Quote, or Release During Review** *******

9 - 55 proposed rules, several commenters suggested that we undertake an employ ment anal ys is for the final rulemaking. Consistent with Executive Order 13563 , we have provided a discus sion of the potential employ

ment impacts of the Heavy- Duty National Program . In recent rulemakings, EPA has generally focused its employ

ment anal ys is on the regulated sector and the suppliers of pollution abatement equipment. However, in this rule, the agencies are offering qualitative assessment for related industries of interest. For the regulated sector, the agencies rel y on Morgenstern et al. for guidance. 35 Our general conclusion is that employ ment impacts in the regulated sector (truck and engine manufacturing) and the parts sectors depend on a combination of factors, some of which are positive, and some of which can be positive or negative . In the related industries, the anal ys is concludes that effects on employ ment in the transport and shipping sectors are ambiguous; the fuel supplying sectors may face reduced emplo ym ent; and there may be increased general emplo ym ent due to reduction in costs that may

be passed along to the transport industry and thus to the public. Because measuring emplo ym ent effects depends on a variety of inputs and assumptions, some of which are known with more certainty than others, and because we did not include employ ment anal ys is in the NPRM and provide opportunity for public comment on the methods, we here present a qualitative discussion. Because the discussion is qualitative, and we thus do not know magnitudes (and, in some cases, directions), we do not sum the net effects on employ ment. We also note that the employment effects may be different in the immediate implementation phase than in the ongoing compliance phase; this analy sis focuses on the longer- term effects rather than the immediate effects. When the economy is at full employment, an environmental regulation is unlikely to have much impact on net overall U.S . employ ment ; instead, labor would primarily be shifted from one sector to another. These shifts in employ ment impose an opportunity cost on society , approximated by

the wages of the employees, as regulation diverts workers from other activities in the eco nomy. 36 Inthis situation, any effects on net employ

ment are likel y to be transitory as workers change jobs . For example , some workers may need to be retrained or require time to search for new jobs, while shortages in some sectors or regions could bid up wages to attract workers. R It is also true that , if a regulation comes into effect during a period of high unemploy ment, a change in labor demand due to regulation may affect net overall U.S. employ ment because the labor market is not in equilibrium. Either negative or positive effects are possible. Schmalansee and Stavins 37 point out that net positive employ ment effects are possible in the near term when the economy is at less than full employ ment due to the potential hiring of idle labor resources b y th e regulated sector to meet new requirements (e.g., to install new equipment) and new economic activity in sectors related to the regulated sector. In the longer run, the net effect on employ ment is more difficult to predict and will depend on the way in wh ich the related industries respond to the regulatory requirements. As Schmalansee and Stavins note, it is possible that the magnitude of the effect on emplo ym ent could vary over time,

R Although the employment level would not change substantially, there would be costs to the workers associated with shifting from one activity to another. Jacobson, Louis S., Robert J. LaLonde, and Daniel G. Sul livan, “Earnings Losses of Displaced Workers.” American Economic Review 83(4) (1993): 685 - 709.**Regulatory Impact Analysis**

region, and sector, and positive effects on employment in some regions o r sectors could be offset by negative effects in other regions or sectors. For this reason, they urge caution in reporting partial employ

ment effects since it can “paint an inaccurate picture of net employ ment impacts if not placed in the broader economic context.” This rulemaking is expected to have a relativel y s mall effect on net employment in the United States through the regulated sector

– the truck and engine manufacturer industry

– and several related sectors, specificall y, industries that suppl y the truck and engine manufacturing industry (e.g., truck parts), the trucking industry itself, other industries involved in transporting goods (e.g., rail and shipping); the petroleum refining sector, and the retail sector. According to the U.S. Bureau of Labor Statistics, about 1.25 million people were employed in the truck transportation industry

and about 675,000 people were employed in the motor vehicle parts industry between 2010 and 2011. 38 Although heavy- duty vehicles (HD) account for approximatel y 4 percent of the vehicles on the road, these vehicles consume more than 20 percent of on - road gasoline and diesel fuel use. As discussed in Chapter 5 of this RIA, this rulemaking is predicted to reduce the amount of fuel these vehicles use, and thus aff ect the petroleum refinery

industry . The petroleum refinery industry employed about 65,000 people in the U.S. in 2009, the most recent ye ar that emplo yment estimates are available for this sector. 39 Finally , since the net reduction in cost associated with th e s e rule s is expected to lead to lower transportation and shipping costs, in a competitive market a substantial portion of those cost saving s will be passed along to consumers, who then will have additional discretionary income (how much of the cost is passed along to consumers depends on market structure and the relative price elasticities). Determining the direction of employ ment effects even in the regulated industry may be difficult due to the presence of competing effects that lead to an ambiguous adjustment in employ ment as a result of environmental regulation. Morgenstern, Pizer and Shih40 identify three separate way s that employ ment levels may

change in the regulated industry in response to a new (or more stringent) regulation.  Demand effect: h igher production costs due to the regulation will lead to higher market prices ; higher prices in turn reduce demand for the good, reducing the demand for labor to make that good. In the authors’ words, the “extent of this effect depends on the cost increa se passed on to consumers as well as the demand elasticity of industry

output.”  Cost effect : As go up, plants add more capital and labor (holding other factors constant), with potentially

positive effects on employ ment; in the authors’ words, as “producti on costs rise, more inputs, including labor, are used to produce the same amount of output.”  Factor-shift effect : post - regulation production technologies may be more or less laborintensive (i.e., more/less labor is required per dollar of output). In the authors’ words, “environmental activities may be more labor intensive than conventional production,” meaning that “the amount of labor per dollar of output will rise,” though it is also possible that “cleaner operations could involve automation and les s employ ment, for example.” The “demand effect” is expected to have a negative effect on emplo ym ent, the “cost effect” to have a positive effect on employ ment, and the “factor- shift effect” has an ambiguous effect on******* **E.O. 12866 Review –**  **Revised Version –**  **Do Not Cite, Quote, or Release During Review** *******

9 - 57 employ ment. Without more information w ith respect to the magnitudes of these competing effects, it is not possible to predict the total effect environmental regulation will have on employ ment levels in a regulated sector . Morgenstern et al. estimate d the effects on emplo yment of spending on po llution abatement for four highly polluting/regulated industries (pulp and paper, plastics, steel, and petroleum refining). They conclude that increased abatement expenditures generall y have not caused a significant change in employ ment in those sectors. More specifically , their results show that, on average across the industries studied, each additional $1 million spent on pollution abatement results in a (statistically insignificant) net increase of 1.5 jobs. While the specific sectors Morgenstern et al. examined are different than the sectors considered here, the methodology

that Morgenstern et al. developed is useful in this context. 

### 9.9.2 **Overview of Affected Sectors**  The above discussion focuses on employ ment changes in the regulated sector, but the regulate d sector is not the only source of changes in employ ment. In these rules, the regulated sectors are truck and engine manufacturers; they are responsible for meeting the standards set in these rules. The effects of these rules are also likely to have impacts beyond the directl y regulated sector. Some of the related sectors which these rules are also likely to impact include: motor vehicle parts producers, to the extent that the truck and engine industries purchase components rather than manufacture them in - house; shipping and transport, because many companies in this sector purchase trucks and their operating costs will be affected by both higher truck prices and fuel savings; oil refineries due to reduced demand for petroleum - based fuels; and the final r etail market, which is where any net cost reductions due to fuel savings are ultimately

expected to be experienced. We acknowledge that there may be impacts in other sectors that are not discussed here, but we have sought to include the sectors where we t hink the impacts are most direct. The foll owing discussion describes the direction of impacts on employ ment in these industries. The effects of the HD rule on net U.S. employ ment depend, not only on their relative magnitudes, but also on employ ment level s in the overall economy. As previously

discussed, in a full - employ ment economy

these sector- specific impacts will be mostly offset b y emplo ym ent changes elsewhere in the economy and would not be expected to result in a net change in jobs. However, in an economy with significant unemplo yment these changes may affect net employ

ment in the U.S. 

### 9.9.2.1 **Truck and Engine Manufacturers**  The regulated sector consists of truck and engine manufacturers. Emplo yment associated with manufacturing trucks and engines may be a ffected b y the demand, cost, and factor - shift effects. 

### 9.9.2.1.1 Demand Effect The demand effect depends on the effects of this rulemaking on HD vehicle sales. If vehicle sales increase, then more people will be required to assemble trucks and their components. If vehicle sales decrease, emplo ym ent associated with these activities will unambiguousl y decrease. The effects of this rulemaking on HD vehicle sales depend on the**Regulatory Impact Analysis**

9 - 58

perceived desirability of the new vehicles. Unlike in Morgenstern et al.’s study , where the demand effect decreased employ ment, there are countervailing possibilities in the HD market due to the fuel savings resulting from this program. On one hand, this rulemaking will increase vehicle costs; b y itself, this effect would reduce vehicle sales . In addition, while decreases in vehicle performance would also decrease sales , this rule is not expected to have any negative effect on vehicle performance . On the other hand, this rulemaking will reduce the fuel costs of operating the vehicle; by

itse lf, this effect would increase vehicle sales, especiall y if potential buyers have an expectation of higher fuel prices. The agencies have not made an estimate of the potential change in vehicle sales. However , as discussed in Preamble Section VIII.E.5 , the agencies have estimated an increase in vehicle miles traveled (i.e., VMT rebound) due to the reduced operating costs of trucks meeting these new standards. Since increased VMT is most likely to be met with more drivers and more trucks, our projection o f VMT rebound is suggestive of an increase in vehicle sales and truck driver employ ment (recognizing that these increases may be partiall y offset by a decrease in manufacturing and sales for equipment of other modes of transportation such as rail cars or b arges). As discussed in Preamble Section VIII.A., the agencies find that the reduction in fuel costs associated with this rulemaking outweigh the increase in vehicle cost. This finding is puzzling insofar as market forces should lead truck manufacturers and buyers to install all cost effective fuel - saving technology , but the agencies find that they have not. Preamble Section VIII.A discusses various hy potheses that have been suggested to explain this phenomenon. Some of the explanations suggest that vehicle manufacturers and buyers will benefit from the rulemaking, and vehicle sales will increase; others suggest that the opposite might occur. The agencies do not have strong evidence supporting one specific explanation over another. As a result, the ag encies do not suggest a direction for changes in employ ment due to changes in vehicle sales . However, some in the heavy- duty i ndustry indicate the potential for an increase in jobs. As stated by Tom Linebarger (President and Chief Operatin g Officer of Cummins ) and Fred Krupp (President of the Environmental Defense Fund), "Finally , strong environmental standards play

a crucial role in getting innovations to market that will create economic opportunity

for American companies and jobs for American workers. . . . It helps that Cummins and other forward - thinking businesses view this as an opportunity to innovate and increase international market share." 41 

### 9.9.2.1.2 Cost Effect The truck and engine manufacturing sector has great flexibility in how to respond to the requirement for reduced greenhouse gases and increasing fuel efficiency , with a broad suite of technologies being available to achieve the standards . These technologies are described in detail in Chapter 2 of this RIA. Among these technologies, a distinctio n can be made between technologies that can be “added on” to conventional trucks versus those that replace features of a conventional truck. “Added on” features , such as auxiliary power units, require additional labor to install the technologies on trucks , thus clearl y i ncreasing labor demand (the “cost effect”). The pure cost effect always increases employ ment, though the net effect on the regulated industry depends on its effects in combination with the demand and factor - shift effects. 

### 9.9.2.1.3 Factor- Shift Effe ct******* **E.O. 12866 Review –**  **Revised Version –**  **Do Not Cite, Quote, or Release During Review** *******

9 - 59 For “replacement” technologies, the predicted impact on labor demand from regulation depends on the change in the amount of labor used build and to install one type of technology compared to another. In some cases, the new technologies are predicted to be more complex than the existing technologies and may therefore require additional labor installation inputs. In other cases, the opposite may be true: labor intensity

may be lower for some replacement technologies. M ost of the technologies that are exp ected to be used to meet these standards are replacement technologies. For example, almost all of the engine improvements involve replacement technologies that are not expected to significantl y change the labor requirements. Similarly, regulations of the chassis on vocational vehicles will only require the installation of a different type of tire, which is also not expected to have large labor intensity impacts. Therefore, the potential magnitude of the factor shift effect is expected to be relativel y sm all, though perhaps slightly

positive due to the additional labor needed to install more complex technologies. 

### 9.9.2.1.4 Summary for the Truck and Engine Manufacturing Sector For the truck and engine manufacturing sector, the demand effect may result in either in creased or decreased employ ment; the cost effect is expected to increase employ ment; and the factor- shift effect is expected to have a small, possibly slightl y positive effect on employment in this sector. The net effect on employ ment in this sector depends on the sum of these factors. 

### 9.9.2.2 **Motor Vehicle Parts**  **Manufacturing Sector**  Some vehicle parts are made in - house and would be included directly in the regulated sector . Others are made by independent suppliers and are not directl y regulated, but they will b e affected b y the rules as well. The parts manufacturing sector will be involved primaril y in providing “add - on” parts, or components for replacement parts built internally . If demand for these parts increase s due to the increased use of these parts , emp loy ment effects in this sector are expected to be positive. If the demand effect in the regulated sectors is significantly negative enough, it is possible that demand for other parts may decrease. As noted, the agencies do not predict a direction for the demand effect. 

### 9.9.2.2.1 Transport and Shipping Sectors Although not directl y regulated by these rules, employ ment effects in the transport and shipping sector are likel y to result from these regulations. I f the overall cost of shipping a ton of freight decreases because of increased fuel efficiency (taking into account the increase in upfront purchasing costs), in a perfectl y competitive industry these costs savings will be passed along to customers. With lower prices, demand for shipping would lead to an increas e in demand for truck shipping services (consistent with the VMT rebound effect anal ys is) and therefore an increase in employ

ment in the truck shipping sector . In addition, if the relative cost of shipping freight via trucks becomes cheaper than shipping by other modes (e.g., rail or barge), then employ ment in the truck transport industry is likely to increase. If the trucking industry is more labor intensive than other modes, we would expect this effect to lead to an overall increase in employ ment in the transport and shipping sectors. Such a shift would, however, be at the expense of employ

ment in the sectors that are losing business to trucking. The first effect

– a**Regulatory Impact Analysis**

9 - 60

gain due to lower shipping costs

– is likely to lead to a net increase in employ ment. The second effect, due to mode - shifting, may increase employment in trucking, but decreases in other shipping sectors. 

### 9.9.2.2.2 Fuel Suppliers In addition to the effects on the trucking industry and related truck parts sector, these rules will result in reductions in fuel use that lower GHG emissions. Fuel saving, principally reductions in liquid fuels such as diesel and gasoline, will affect emplo ym ent in the fuel suppliers industry sectors, principally

the P etroleum Refinery

sector. 42 Expected fuel consumption reductions b y fuel typ e, and b y heavy- duty vehicle type, can be found in Table VIII - 7. These reductions reflect impacts from the new fuel efficiency and GHG standards and include increased consumption from the rebound effect. These fuel savings are monetized in Table VIII - 8 by multiplying the reduced fuel consumption in each ye ar b y the corresponding estimated average fuel price in that year, using the Reference Case from the AEO 2011. In 2014, the pre - tax fuel savings is $1.2 billion (2009$). While the se figures represent a level of fuel savings for purchasers of fuel, it also represents a loss in value of output for the petroleum refinery

industry . Since 50 percent of the fuel would have been refined in the U.S., the loss in output to the U.S. Petroleum Refinery sector is $600 million (2009$), which will result in reduced sectoral employ ment. 43 Because this sector is very capital - intensive, the employ ment effect is not expected to be large. 

### 9.9.2.2.3 Fuel Savings As a result of this rulemaking, it is anticipate d that trucking firms will experience fuel savings. Fuel savings lower the costs of transportation goods and services. In a competitive market, the fuel saving that initially accrue to trucking firms are likel y to be passed along as lower transportation costs that, in turn, could result in lower prices for final goods and services. Alternativel y, the savings could be kept internall y in firms for investments or for returns to firm owners. In either case, the savings will accrue to some segment of consumers: either owners of trucking firms or the general public. In both cases, the effect will be increased spending b y consumers in other sectors of the economy , creating jobs in a diverse set of sectors, including retail and service industries. As mentione d above, the value of fuel savings from this rulemaking is projected to be $1.2 billion (2009$) in 2014, according to Table VIII - 8. If all those savings are spent, the fuel savings will stimulate increased employ ment in the economy through those expenditures. I f the fuel savings accrue primarily to firm owners , they may either reinvest the money or take it as profit. Reinvesting the money in firm operations would increase employment directly . If they take the money

as profit, to the extent that these o wners are wealthier than the general public, they may spend less of the savings, and the resulting employ ment impacts would be smaller than if the savings went to the public . Thus, while fuel savings are expected to decrease employ ment in the refinery

sec tor, they

are expected to increase employ ment through increased consumer expenditures.******* **E.O. 12866 Review –**  **Revised Version –**  **Do Not Cite, Quote, or Release During Review** *******

### 9.9.3 **Summary** The net emplo ym ent effects of this rulemaking are expected to be found throughout several key

sectors: truck and engine manufacturers, the trucking industry , tru ck parts manufacturing, fuel production, and consumers. For the regulated sector, the demand effect may result in either increased or decreased employ ment, depending on the net effect on HD vehicle sales ; the cost effect is expected to increase employment in the regulated sector; and the factorshift effect is expected to have a small, possibly slightly positive effect on employ ment, though we cannot definitively

say this is the case without quantification. The net effect depends on the combination of the se effects. In creased expenditures by truck and engine parts manufacturers are expected to require increased labor to build parts , though this effect also depends on any changes overall demand, and on in the labor intensity of production of new parts ; inc reased complexity

of technologies may

impl y increased labor inputs for some parts, though others might be less labor- intensive . It is possible, if access to capital markets is limited, that this rule might displace other HD sector investment, which would reduce employ ment associated with those activities. Lo wer prices for shipping are expected to lead to an increase in demand for truck shipping services and, therefore, an increase in employ ment in that sector , though this effect may be offset somewhat b y changes in employ ment in other shipping sectors . Reduced fuel production implies less employ ment in the fuel provision sectors. Finall y, any net cost savings would be expected to be passed along to some segment of consumers: either the general public or the owners of trucking firms, who are expected then to increase employ ment through their expenditures . Given the job creation as a result of the $1.2B (2009$) in fuel savings in 2014 and the possible employ

ment increases in the manufacturing and parts sectors, we find it highl y unlikely that there would be significant net job losses related to this policy . Given the current level of unemplo ym ent, net positive employ ment effects are possible, especially in the near term, due to the potential hiring of idle labor resources by the regulated sector to plan for and meet new requirements. In the future, when full employment is expected to return, any changes in employ ment levels in the regulated sector due to this program are mostly expected to be offset b y chan ges in emplo ym ent in other sectors.**Regulatory Impact Analysis**

These estimates are derived from time - series re gression of annual national aggregate VMT for the period 1970 - 2008 on measures of nationwide economic activity, including aggregate GDP, the value of durable and nondurable goods production, and the volume of U.S. exports and imports of goods, and variable s affecting the price of trucking services (driver wage rates, truck purchase prices, and fuel costs), and from regression of VMT for each individual state over the period 1994 - 2008 on similar variables measured at the state level. 21 Memo from Energy and Environmental Research Associates, LLC Regarding HDV Rebound Effect, dated June 8, 2011. 22 Docket ID EPA - HQ - OAR - 2009 - 0472 - 114577, Technical Support Document: Social Cost of Carbon for Regulatory Impact Analysis Under Executive Order 12866, Interagency Wor king Group on Social Cost of Carbon , with participation by Council of Economic Advisers, Council on Environmental Quality, Department of Agriculture, Department of Commerce, Department of Energy, Department of Transportation, Environmental Protection Agenc y, National Economic Council, Office of Energy and Climate Change, Office of Management and Budget, Office of Science and Technology Policy, and Department of Treasury (February 2010).

9 - 64 23 The interagency group decided that these estimates apply only to CO 2 emissions. Given that warming profiles and impacts other than temperature change (e.g. ocean acidification) vary across GHGs, the gro up concluded “transforming gases into CO 2 - equivalents using GWP, and then multiplying the carbon equivalents by the SCC, would not result in accurate estimates of the social costs of non - CO 2 gases” (SCC TSD, pg 13). 24 The SCC estimates were converted from 2007 dollars to 2008 dollars using a GDP price deflator (1.021) and again to 2009 dollars using a GDP price deflator (1.009) obtained from the Bureau of Economic Analysis, National Income and Product Accounts Table 1.1.4, Prices Indexes for Gross Domestic Product . 25 National Research Council (2009).

Of this latter figure, 90 percent is anticipated to reduce U.S. imports of crude petroleum for use as a refinery feedstock, while the remaining 10 percent is expected to reduce U.S. domes tic production of crude petroleum. Because we do not expect to see a significant reduction in crude oil production in the U.S., we do not expect this rule to have a significant impact on the Oil and Gas Extraction industry sector in the U.S. (NAICS 211000 ).
