SUMMARY

The 101st Congress, in amending the Clean Air Act (P.L. 101-549), established new programs designed to produce both cleaner cars and cleaner fuels as elements of an enlarged campaign against urban air pollution. In addition to tightening emission standards for conventional vehicles using conventional fuels, the amendments set up a pilot clean car/clean fuel program for both fleet and private California vehicles, starting in model year (MY) 1996, and for fleet vehicles in the more-polluted ozone and carbon monoxide (CO) nonattainment areas outside of California starting in MY1998. The clean fuels envisioned include clean gasoline, natural gas, propane, methanol, ethanol, and over a longer time frame, hydrogen and electricity.

CO nonattainment areas are required to provide oxygenated gasoline from November through February each year, starting in November 1992. The amendments also require that gasoline for use by all vehicles, not just clean fuel vehicles, in the nine worst ozone nonattainment areas be reformulated to generate fewer emissions of ozone-forming and toxic pollutants. This reformulated gasoline (RFG) is to be sold in the nine areas starting in 1995; other ozone nonattainment areas can opt in to the program on application.

In December 1993, EPA issued its rule defining the RFG program. One important issue, however, the role of ethanol in refor-mulated gasoline, remained unresolved. A White House proposal by President Bush in October 1991 that 30% of the oxygen be derived from renewable resources was put forth by EPA for comment in mid-December 1993. Refiners, the methanol industry, and some environmentalists opposed the requirement. The ethanol industry and the agricultural sector supported it. EPA issued the rule on June 30, 1994. The American Petroleum Institute, National Petroleum Refiners Association, and American Methanol Institute sued to block implementation. On September 13, the U.S. Court of Appeals for the District of Columbia issued a stay, blocking implementation. On Apr. 29, 1995, the Court rejected the rule, concluding that EPA lacked the authority to specify "the manner of compliance or the precise formula."

Currently, ethanol has between 5 and 10% of the RFG oxygenate market, mostly in the Chicago and Milwaukee areas.

The 102nd Congress, in its last days, passed the Energy Policy Act of 1992 (P.L. 102-486), a 31-title bill containing a modest alternative fuels mandate. The program focuses on fleet vehicles owned and operated by Federal, State, and municipal governments, plus those owned and operated by companies involved in alternative fuels production, distribution, or marketing. Private fleets must purchase AFVs, starting in 1999, with the percentages of AFVs increasing from 20% in 1999 to 70% in 2006 and thereafter. States are invited to develop their own programs of economic and regulatory incentives to promote use of alternative fuels in vehicles other than their own and to apply for Federal financial and technical assistance to implement their programs. The conference agreement also provides tax incentives for the purchase of alternative fuel vehicles and for development of retail service stations. These incentives phase out in 2004.

MOST RECENT DEVELOPMENTS

The U.S. Court of Appeals for the District of Columbia, which in September 1994 stayed EPA's rule mandating the use of ethanol in RFG, heard oral arguments in the case in February 1995 and ruled in April 1995 that EPA did not have the authority to mandate ethanol use. The court refused to hear an appeal by EPA.

Counties in Pennsylvania, New York, Maine, and Wisconsin which opted in to the RFG program before it began have opted out for reasons of cost or alleged health and performance effects. Interest in other ozone nonattainment areas in opting in to RFG is currently very low. New studies of health effects and engine performance are under way.

The Department of Energy (DoE) has issued proposed rules defining the requirements for AFV purchases applicable to fleet vehicles owned by providers of alternative fuels, establishing a credit program for fleets which purchase AFVs sooner than required or purchase more vehicles than required, and establishing the criteria under which States can set up incentive programs for purchasers of AFVs in their States. Neither the House- nor the Senate-passed appropriations bills funding DOE alternative fuels programs for FY1996 provide funds to cover the incremental costs of acquiring alternative fuel vehicles for the Federal fleet. The House Appropriations committee has attached a series of riders to EPA appropriations one of which would prevent EPA from making further efforts to mandate a market share for ethanol in RFG. The Senate Appropriations Committee bill did not include such a rider. In conference, all but one of the riders were removed. The one remaining deals with foreign refiner baselines for reformulated gasoline.

BACKGROUND AND ANALYSIS

History of Vehicle Emission Controls

The Clean Air Act first provided authority to establish Federal emission standards for automobiles and light trucks in 1963; most other mobile sources were regulated subsequently. These Federal standards first took effect with the 1968 model year and preempted State auto emission standards, except for California, which is permitted to request a waiver annually to allow stricter standards. EPA conducts a testing and certification program to ensure that new model vehicles -- including imports -- meet the standards.

The 1970 Act required that emissions of CO and HC be reduced 90% by 1976 and emissions of nitrogen oxides (NOX) be reduced 90% by 1976 from the emissions allowed in 1970. In 1973 the EPA Administrator delayed the deadlines and set interim standards. The 1977 amendments further delayed the deadlines, to 1982 for CO and HC, and to 1985 for NOX; also, the emission reduction goal for NOX was reduced to 75%, with the 90% reduction set as a research goal.

The 1977 amendments also mandated equivalent reductions in emissions from heavy duty trucks, to be effective in 1982 for HC and CO and in 1983 for NOX and particulates. Through a series of administrative and technical delays, the schedules for NOX and particulates were delayed until 1994, with interim standards to be met in intermediate years.

Faced with the forecast that vehicle emissions would not be reduced enough by the mandated standards to compensate for the inexorable increase in vehicle miles traveled, Congress in the 1990 Amendments tightened emission standards again (for cars, the HC standard is reduced by 40%, the NOX standard by 60%). These standards will be phased in over the 1994-6 model years. If a study due in 1997 shows both that significant numbers of cities remain out of attainment and that technology at reasonable cost is available, another round of tightened standards will be imposed in 2004. For heavy duty trucks, the NOX standard was delayed until 1998 to allow more time for the necessary technologies to be developed.

Because emissions vary so widely as vehicles age, EPA has been concerned that these two new rounds of tighter emission standards will probably exhaust the potential for reduced vehicle-related emissions so long as conventional gasoline and diesel oil remained the predominant motor vehicle fuels. Yet VMT will continue to increase, so that by 2010 at the latest, vehicle-related emissions will again be increasing. Alternative fuels such as methanol, ethanol, natural gas, propane, and perhaps hydrogen or fuel cells, show promise in both theory and test use of being intrinsically less ozone-forming both in themselves and through their tailpipe emission products. Experience in Denver and other cities has demonstrated that adding oxygen, either in alcohol or ether form, to gasoline significantly reduces CO emissions, particularly in older cars and in newer cars whose engines or emission control equipment are not functioning properly.

In response to these considerations, the 1990 Amendments require that gasoline sold in CO nonattainment cities contain at least 2.7% oxygen, starting in 1992. The Amendments also require that a cleaner, "reformulated" gasoline be sold, starting in 1995, in the nine worst ozone nonattainment areas (Los Angeles, San Diego, Houston, Baltimore, Philadelphia, New York, Hartford, Chicago, and Milwaukee). Other ozone nonattainment areas will be able to opt in to the reformulated gasoline program as supplies of reformulated gasoline expand.

Alternative fuels other than gasoline will be stimulated by two programs. California has developed a program requiring low emission vehicles (LEVs) and ultralow emission vehicles (ULEVs) to be introduced starting in 1996 at 150,000 vehicles per year and rising to 300,000 vehicles per year in 1999. Second, in all of the most seriously polluted ozone nonattainment areas and the worst CO nonattainment areas (about two dozen metropolitan areas), centrally fueled fleets of 10 or more vehicles become subject to a requirement, starting in 1998, that a portion of any new vehicles be "clean fuel vehicles." The portion is 30% in 1998, 50% in 1999, and 70% in 2000 except for heavy duty trucks (constant at 50%). The clean fuel vehicles must be the same as those sold in California, and the fleet program applies to California fleets as well.

Gasoline, no matter how reformulated, was not expected to be a contender for qualification as a "clean alternative fuel." However, it is not closed out by definition, so it might qualify as a result of advances in technology in either the vehicle, the gasoline formulation, or some combination of these. Recent advances in both vehicle technology and emission control technology for gasoline-fueled cars have led to a growing consensus that, except for zero emission vehicles, gasoline will carry the day unless additional regulatory requirements beyond those in the Clean Air Act Amendments are put in place by State authorities. However, the potential for diesel fuel to meet the "clean alternative fuel" standards for heavy duty engines is more problematic.

Implementation Issues

Although there is considerable evidence that tighter emission standards in new cars, oxygenates in gasoline, reformulated gasoline, and alternative fuels will all contribute to reduced emissions from vehicle traffic, a number of very difficult practical obstacles must be overcome before these changes can be put into place on a large scale and make a measurable difference in air quality. These issues will play out over a number of years, as experience is gained and fed back into design, engineering, and production of both vehicles and fuels.

EPA and other interested parties participated in a year-long regulatory negotiation process (reg-neg) to streamline to the extent possible the process of rulemaking and implementation for the gasoline-related regulatory requirements. This process concluded with an agreement signed in August 1991 by auto, oil, ethanol, methanol, and environmental interests, as well as the EPA itself.

Oxygenated Fuels for CO Nonattainment Areas

The first deadline of significance was adding oxygenates to gasoline in some 40 cities starting in the 1992-3 winter. The amended Act requires no less than 2.7% oxygen no later than November 1 each winter, continuing through the end of February (some individual cities are subject to longer periods because of local conditions).

The 40 cities consume some 2.8 billion gallons of gasoline per month (29% of national demand). Most of the oxygen is being supplied in either one of two forms -- ethanol or methyl tertiary butyl ether (MTBE), although, since EPA promulgated a "sub-sim" rule (56 FR 5352, Feb. 11, 1991) defining a wide range of gasoline formulation as "substantially similar" to gasoline, methanol, tertiary butyl alcohol (TBA), ethyl tertiary butyl ether (ETBE), other ethers, and mixtures of some of these are playing minor roles. Mandated oxygen demand will be 2.7% of the 2.8 billion gallons, or 80 million gallons per month (some 330,000 bbl/day if it were all MTBE).

Early in the 1992-3 winter, complaints began arising about nausea, headaches, and other health effects allegedly caused by MTBE-containing gasoline. Alaska was the source of most complaints, although some also arose in other areas. EPA and the MTBE industry immediately reviewed the many health studies and initiated more. Currently it appears that the complaints cannot be tied to the presence of MTBE, but the issue remains active, particularly in Alaska and New Jersey and, more recently, in Wisconsin and Texas.

During the 1993-94 control period, contract oxygenate prices for control period delivery were firm at about $1.10 per gallon for MTBE and about $1.30 per gallon for ethanol. Spot prices remained soft throughout the winter (60-70 cents per gallon for MTBE, $.95-$1.05 per gallon for ethanol), led in part by low oil prices and in part by plentiful oxygenate supplies.

Both ethanol and MTBE prices were soft in 1994 until late summer, when escalating methanol prices, plus the forthcoming winter oxygenate season, caused MTBE prices to rise. The cycle of higher prices during the winter oxygenate season and lower prices the rest of the year continued in 1995, despite the additional oxygenate demand created by the first year of mandated RFG use.

Price pressure from increased oxygenate demand in the winter may not be as great in the future as it has been for the past several years. A number of carbon monoxide nonattainment areas are coming into compliance, are being redesignated as attainment, and are or soon will be no longer subject to the 2.7% oxygen minimum. In most of these areas, oxygenate use will continue, but at a somewhat lower concentration than 2.7%.

Reformulated Gasoline (RFG)

As indicated earlier, P.L.101-549 mandates the sale of reformulated gasoline in the nine worst ozone nonattainment areas, beginning Jan. 1, 1995. These cities have gasoline demands of about 1.9 billion gallons per month, representing about 19% of national gasoline demand. Six of these areas (Los Angeles, New York, Baltimore, San Diego, Philadelphia, and Hartford) are also CO nonattainment areas; hence their monthly winter demand for oxygenate is accounted for above. Chicago, Houston, and Milwaukee, however, represent further mandated oxygenate demand.

The six ozone/CO areas will have to have 2.0% oxygen for 8 months and 2.7% for 4 months (the mandated 4 months becomes about 5 months, as some time is needed before the startup date to feed the oxygenate into inventory and to service stations). The other three will have to have 2.0% oxygen year-round and represent additional mandated oxygenate demand of about 10 million gallons of oxygen per month (2% of 500 million gallons of gasoline per month).

Ozone nonattainment cities other than the nine specified in the legislation for receipt of reformulated gasoline in 1995 can opt in to the program. Connecticut, Delaware, Kentucky, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, Pennsylvania, Rhode Island, Texas, and Virginia have opted in for their nonattainment areas. The whole State of New York opted in. Other States are also considering opting in. The more areas that opt in, the greater the demand for reformulated gasoline will be. However, as the 1995 RFG entry date approached, 28 counties in Pennsylvania, nine in New York, and two in Maine opted out, choosing alternative means of achieving the needed emissions reductions. Gasoline price increases and concerns about supply were the primary reasons. In February 1995, Wisconsin asked that sales of RFG be temporarily suspended, citing health effects as the stimulus. The request was denied, but the health effects issue remains alive.

Reformulated gasoline is much more than oxygen content. The law requires that it have, besides 2.0% oxygen, a maximum benzene content of 1.0% and no heavy metals. It must meet three performance specifications: from a baseline of standard vehicles using a standard gasoline, ozone-forming VOC emissions must, during the high ozone season, be at least 15% less; toxic air pollutant emissions (benzene, butadiene, formaldehyde, acetaldehyde, and polycyclic organic matter [POM]) must be at least 15% less throughout the year; and NOX emissions cannot be more than the baseline. By 2000, the 15% reductions are to be replaced with 25% reductions (administratively adjustable based on evidence available at the time).

EPA was required to issue, within one year of enactment, regulations specifying how the reformulated gasolines' compositions and performances are to be measured and how qualifying fuels are to be certified. EPA was, also in the same time frame, to define the baseline emission levels for VOCs and air toxics. It missed the deadline (Nov. 15, 1991). EPA tried to provide some certainty by agreeing to a "simple model" as the basis for reformulated gasoline certification in 1995 and 1996, while developing a "complex model" for use thereafter. The simple model relies on volatility and oxygen content (56 FR 31176, July 9, 1991, and 57 FR 13416, Apr. 16, 1992).

The oil industry prepared to produce reformulated gasoline for 1995 on the basis of the "simple model" in the reg-neg agreement. However, there was a concern on the part of the ethanol industry, that the performance requirements for reformulated gasoline, which include sharp restrictions on fuel volatility, would preclude the use of ethanol at gasohol concentrations (10%) and would make it difficult, particularly in the first 2 years, when the simple model dominates, for ethanol at any concentration to be a component of reformulated gasoline. The industry was concerned that both California's final rule and EPA's proposed rule set volatility standards that seemed to preclude ethanol use without either a volatility waiver or a major additional change in gasoline composition. Ethanol interests sought to include in energy legislation, the Energy Policy Act in the 102nd Congress, some proposed remedies for this concern. Since the Energy Policy Act as passed was silent on this issue, the debate focussed on EPA and the White House as EPA prepared the final rule on reformulated gasoline.

On Oct. 1, 1992, the White House, responding at least in part to intense pressure from the National Corn Growers Association and the Renewable Fuels Association, intervened in the rule-making process. It decreed that in Northern ozone nonattain-ment areas where the reg-neg agreement had accepted an RVP of 8.1 psi for RFG, an RVP of 7.8 would be required. Up to 30% of the RFG sold would be granted a 1 psi waiver so that ethanol could be used as the oxygen source. The idea was that the average RVP would still meet the original 8.1 psi level. The State could grant the waiver to more than 30% of the RFG by requiring a commensurate reduction in base RVP. Alternatively, the State could take credit for the emission reductions inherent in a 7.8 RVP RFG, should less ethanol be used than would have been allowed.

In the Southern ozone nonattainment cities, where the reg-neg agreement had specified an RVP of 7.2, up to 20% of the gasoline could be granted a 1 psi waiver, while the base RVP would be reduced to 7.0.

This intervention by the White House was viewed by a number of participants in the reg-neg process as invalidating the reg-neg agreement, in which the Administration was one of the signatories. With respect to RFG, the environmentalists, the oil industry, and the methanol industry believed that their interests would be damaged -- the environmentalists primarily because of their views that NOX emissions would increase in violation of the Clean Air Act's requirement that they not do so; the oil industry because it would be required to bear the additional costs (estimated by the White House to be 0.3 cents per gallon but estimated by the industry to be much higher because of, among other factors, the distribution problems associated with additional grades of gasoline); and the methanol and MTBE industries, which stood to lose sales of up to 700 million and 2 billion gallons per year respectively.

The ethanol industry would benefit by a potential increased market, after all opt-ins, of one to two billion gallons per year -- an approximate doubling of its probable share of the national gasoline market prior to White House intervention. This would represent an increased corn demand of 400 to 800 million bushels per year (5 to 10% of current production). The highway tax revenue loss would be $540 million to $1.08 billion per year. The impact on corn prices would probably be modest, with some studies implying it would be negligible and others implying that it might add 8 to 16 cents per bushel.

The final RFG rule was released on Dec. 15, 1993 and published in the Federal Register about 2 months later (59 FR 7716, Feb. 16, 1994). It includes the latest version of EPA's "complex model" which all refineries must use by 1998. Refineries can choose between the "simple model" and the "complex model" until then.

The complex model includes a requirement for a reduction in NOX emissions by 5-7% in Phase II RFG, starting in 2000. The oil industry believes this requirement also violates the reg-neg agreement, which stated there would be no NOX increase. EPA responds that the NOX reduction is an important factor in the agency's estimates of reduction in ozone levels to be derived from the RFG program.

The role of ethanol. The role of ethanol was removed and treated separately in a notice of proposed rulemaking (58 FR 68343, Dec. 27, 1993), wherein 30% of the oxygen required must come from renewable oxygenates (which means in practice, ethanol). The requirement would be year-round; averaging and trading would be allowed. It was promulgated essentially as proposed, and might increase ethanol consumption by as much as 650 million gallons per year in the early years, increasing as additional cities opt into the RFG program.

The methanol and petroleum industries viewed the renewable oxygenate standard (ROS) rule with distaste similar to that they expressed when the renewable mandate was first proposed. Their objections were based on alleged lack of statutory authority on EPA's part, on the economic impacts of the proposal, and on environmental impacts other than on the RFG program.

The issue of environmental impacts ballooned in the first half of 1994 into a major debate. A DOE analysis made prior to the proposed rule's issuance had concluded that the use of ethanol, partly as ethanol and partly as ETBE, would decrease emissions of greenhouse gases and decrease oil imports, both by small amounts. A later, more comprehensive, version of this analysis came to the opposite conclusion, again by small amounts. Analyses by the Department of Agriculture and the Institute for Local Self-Reliance concluded that the environmental and energy impacts would be favorable. Analyses by Resources for the Future and James Sweeney of Stanford University, on the other hand, concluded the opposite. All of the analyses concluded that the differences would be small.

EPA issued its final rule requiring 30% renewable oxygenate (15% the first year) on June 30, 1994. It allowed annual averaging and did not allow a volatility waiver, thus precluding use of ethanol in the summer season, although ETBE could be used. As expected, API, joined by the National Petroleum Refiners Association, and the American Methanol Institute, sued to block implementation.

Several Members of Congress sought to block EPA implementation of the rule by amending EPA's appropriations to prevent expenditure of appropriated funds on its implementation or enforcement. In the House, the move died in the Appropriations Committee. In the Senate, it also failed in committee but was proposed as a floor amendment. After 5 hours of debate, it was tabled 51-50, with Vice President Gore casting the deciding vote.

The issue then moved to the court system. The U.S. Court of Appeals for the District of Columbia decided on Sept. 13, 1994, to issue a stay against implementation of the rule pending judicial review, which will be expedited and may be completed by mid-1995. The Court decided further to deny the API-NPRA-AMI request for a summary reversal of the rule. On Apr. 29, 1995, the Court ruled that EPA did not have legal authority to mandate a specific role for ethanol. The Court has refused to hear an appeal from EPA. The House Appropriations Committee, in marking up EPA appropriations for FY1996, added a provision which would prevent EPA from making any further efforts to mandate a market share for ethanol. This provision did not survive during conference.

Ethanol Tax Incentives. Ethanol from biomass has received special tax incentives since the late 1970s. The incentive is currently 54 cents per gallon of ethanol used as or in highway fuel. As a result of the reformulated gasoline program and the emphasis on reduced gasoline volatility, ethanol is more attractive as a blending agent in the form of the ether (ethyl tertiary butyl ether, or ETBE). The Treasury Department recently ruled (60 FR 40079, Aug. 7, 1995) that the ethanol part of ETBE qualifies for the 54 cents per gallon incentive.

With about 1.1 billion gallons of ethanol per year qualifying for the tax incentive, the cost to the Highway Trust Fund is about $600 million per year. (This is partially offset by reduced commodity price support payments for corn.) As a revenue loss to the Government, this incentive has been under attack by some Members (Senators Bradley and Nickles have made moves to eliminate it). The House Ways and Means Committee originally put in its reconciliation package a provision which would reduce the incentive to 51 cents per gallon, make it available only as a blender tax credit, and limit it to blenders already in operation or under construction as of Sept. 15, 1995. This change, should it be enacted, would sharply reduce the attractiveness of ethanol as a blend component, not only because of the reduction from 54 cents to 51 cents but also because, as a tax credit, it requires that the tax be paid first and be recovered (if there is sufficient tax obligation by the company) through its subsequent income tax filings.

Ethanol advocates claim that currently the loss of revenues to the Highway Trust Fund is more than compensated for by a reduction in price support payments through the Department of Agriculture to corn farmers, resulting from the higher corn prices generated by the increased corn demand. The General Accounting Office (GAO) issued a report in September 1995 which supports this contention.

GAO assumes no change in the corn price support program and assumes that corn production would decline less than corn demand would decline, leading to a significant reduction in corn price. Given these assumptions, its analysis concludes that the increase in price support payments caused by the lower corn prices would be larger than the increase in Highway Trust Fund revenues caused by the lower incentive and the reduced ethanol volumes which would follow, resulting in a net loss of $2.5 to $6.3 billion from 1996 to 2000 compared to the current situation. Where in the range the answer falls depends on a number of other judgments, including how much corn acreage would be planted and how much ethanol would continue to flow into gasoline.

According to the American Corn Growers Association, the Clinton Administration has indicated that it would consider vetoing any bill containing a proposal to eliminate tax incentives for ethanol. This threat, plus widespread resistance to the proposal in both House and Senate, led to removal of the provision from later versions of the reconciliation package.

Foreign Refiner Baselines

Another late-blooming issue was EPA's decision to grant individual baselines to foreign refiners able to document the properties of their 1990 gasolines. This decision upset a number of domestic refiners because foreign refiners are not subject to several provisions of the Clean Air Act that increase domestic refiners' costs. Congress decided to block implementation of the EPA's rule through EPA appropriations bill.

As the RFG startup period of Jan. 1, 1995, approached, concern was expressed that the combination of the RFG rule's complexity and the reduction of gasoline imports expected to result from congressional intervention in the foreign refiner baseline issue would create spot shortages and price spikes. Testimony before the Energy and Power Subcommittee on September 29 included one projection of price increases up to 31 cents per gallon. Price increases have instead been between 5 and 10 cents per gallon, and there have been no shortages. The opt-outs in Pennsylvania, New York, and Maine have reduced demand for RFG by about 7%.

Venezuela has taken its concern over the foreign refiner baseline to the World Trade Organization, where an arbitration process has begun. Meanwhile, the only appropriations bill rider which has survived prohibits EPA from implementing individual baselines for foreign refiners.

Alternative Fuels and Clean Vehicles

EPA has promulgated standards for clean fuel fleet vehicles that for HC and NOX are half the emissions allowed for 1994 conventional vehicles, effective with the 1996 model year. A second phase is mandated for MY2001 cars, with even lower standards. Although the amendments lay out specific emission standards for tailpipe exhausts for cars and light duty trucks, they also provide that any alternative more-stringent set of standards issued by California would preempt those in the amendments.

All ozone nonattainment areas designated Serious, Severe, or Extreme and CO nonattainment areas with CO levels of 16 ppm or higher must revise their SIPs to require that fleets of 10 or more vehicles under the control of a single person must include clean fueled vehicles as part of any new vehicle purchase, starting in 1998. The percentages are 30% in MY1998, 50% in MY1999, and 70% in MY2000 for cars and light duty trucks (LDTs), and 50% for heavy duty trucks. The requirement does not apply to leased and rented cars or law enforcement and emergency vehicles.

California has established a pilot program, starting in MY1996 at 150,000 vehicles per year and expanding in MY1999 to 300,000 per year. Fleet purchases are to be counted towards these target numbers, with other sales to the public at large.

In essence, these amendments were designed to let California lead the way in promoting alternative-fueled vehicles. California has been moving in this direction for more than a decade, has accumulated a great deal of experience and momentum, and has the country's worst air pollution problems as its incentive to keep on moving forward. There are many debates within California, such as how fast, which alternative fuel, how to provide the appropriate incentives and disincentives, and whether to provide for a role for reformulated gasoline as an alternative ("clean") fuel.

California has adopted clean car standards for 1995 and beyond. These new standards call for four new levels of "cleanliness," labeled transitional low emission vehicles (TLEV), low emission vehicles (LEV), ultra low emission vehicles (ULEV), and zero emission vehicles (ZEV). Each level is cleaner than the level before it, with ZEVs envisioned as achievable only with fully electric vehicles. Each year, the rule requires that the new car composite fleet emission level be lower than the year before, thus requiring that an ever larger proportion of ever-cleaner vehicles be sold. ZEV sales must be at least 2% by 1998, increasing each year thereafter, according to the plan. California has also written a new rule for its own reformulated gasoline, approved in late November 1991 to take effect in 1996.

As the deadline (Model Year 1998) for ZEV entry into the new car fleet approaches, and as the problems of battery cost and performance appear to remain formidable, resistance to the ZEV part of the mandate is growing stronger. The California Air Resources Board (CARB) and Governor Wilson continue to affirm their support of the role of ZEVs. As 1996 began, CARB staff proposed that the 2% mandate for 1998 be suspended and that automakers negotiate agreement with CARB on how many ZEVs each would produce. The later year requirements are not yet affected.

Beyond California is the issue of opt-in by other States. Other States can opt in to create a clean car/clean fuel program using the same cars and fuels as are used in California. Other States are authorized to institute incentives for clean cars such as exemption from HOV lane requirements, preferences in parking place assignments, and preferential registration fees. New York and Massachusetts have adopted California's programs.

The auto industry sued, primarily on the basis that not using California gasoline would mean that auto industry would in essence be required to produce a "third car" (U.S., California, and now a New York version) in contravention of Section 177 of the CAAA. The U.S. District Court in the northern district of New York ruled in favor of the auto industry. In July 1993, the New York judge vacated his decision on the basis of new evidence, so New York can now proceed to implement. The auto industry appealed; in February 1994, the Second Circuit Court of Appeals upheld New York's adoption of the LEV program.

Following New York's lead, the Ozone Transport Commission (OTC), which includes the 12 Northeast States and the District of Columbia, voted on Feb. 1, 1994, to petition EPA to impose a commission-wide LEV program. The vote was 9-4. EPA has responded in favor of the OTC petition, allowing each State to decide for itself on the role of ZEVs. New York, Massachusetts, Vermont and Connecticut have included ZEVs in their plans. Negotiations continue, however, among EPA, the auto industry, and other stakeholders for an alternative program under which the auto industry would produce nationally (other than California) cars meeting emission standards more stringent than the current ones -- an alternative which would, the auto industry claims, reduce emissions more than the California option at less cost.

Proposed National Energy Strategy (NES)

In the 102nd Congress, the Bush Administration's National Energy Strategy proposed an intensified alternative fuels program which would displace some 1.35 million barrels of gasoline per day (350,000 from fleets) from use in the transportation sectors by 2010. This is the fuel that would be used by some 65 million cars averaging 30 miles per gallon and driving 10,000 miles per year, or 130 million using alternative fuels half the time.

The alternative fuels provisions of the Clean Air Act are expected to affect 5-10 million cars and perhaps 100,000 barrels of gasoline per day over the same period, unless major market areas other than California opt in to the California program and unless the California requirements are met with cleaner reformulated gasoline and improved vehicle emission control systems. Clearly, the NES proposed a very ambitious program, particularly given that operating experience on alternative fuel cars subject to current and upcoming regulatory requirements is very limited, current U.S. production of alternative-fueled vehicles other than LPG-fueled vehicles produced by retrofit is less than 10,000 per year, there is almost no alternative fuel delivery infrastructure, the fuels and vehicles tend to cost more than gasoline and diesel-fueled systems, and fuel production capacity of this scale would (except for natural gas and LPG) have to be built.

The NES fuel program mandating alternative fuels for fleets would phase in sooner than the Clean Air Act clean car program, would affect small fleets (10 vehicles or more) in nonattainment cities subject to Clean Air Act requirements, and would extend to all cities of over 250,000 regardless of air quality status. In the cities to which the fleet mandate would be extended, fleets of 20 or more would be affected. The NES proposal would omit reformulated gasoline and diesel fuel from the definitions of alternative fuels. This wording change would settle the issue of whether or not the Clean Air Act mandates for fleets would lead to alternative fuel use.

Most of the alternative fuel vehicles claimed by NES to be coming onto the roads by 2010 would get there as a result of (1) development of alternative fuel vehicle (AFV) technologies and economics from the mandated fleet program, (2) a projected approximate doubling in gasoline price over the two decades, and (3) new AFV and fuel production technologies developed under an expanded R&D program in the Department of Energy.

Congressional Debate on Alternative Fuels

The Senate Committee on Energy and Natural Resources in markup on S. 341 (reported as S. 1220), its comprehensive energy policy bill, added an accelerated Federal AFV fleet program to serve as spearhead for its State and private fleet programs (similar to but slightly less restrictive than those proposed in the NES) to follow several years later. This program was approved by the full Senate with minor amendments as part of S. 2166 (successor bill to S. 1220) on Feb. 19, 1992. The House Energy and Power Subcommittee proposed a similar program (somewhat less prescriptive for State and local fleets and focusing on fuel providers' fleets in the private sector) in a bill marked up and approved in subcommittee in October 1991 (H.R. 776). H.R. 776 was reported out to the House from the Energy and Commerce Committee in mid-March 1992. The House Government Operations and Public Works and Transportation Committees, in their markups of H.R. 776, added some detailed provisions related to Federal fleet operations and relationships to transportation programs. These remained in the House-passed version.

Sentiment also had been building in favor of using the tax code to address the unfavorable economics of alternative fuels. S. 1178 (Rockefeller), H.R. 1497 (Andrews), and H.R. 2960 (Synar) took the approach of tax credits for investments in alternative fuel infrastructure and vehicles. The House Ways and Means Committee, in marking up H.R. 776, adopted provisions similar to H.R. 1497, permitting accelerated depreciation of the full cost of the qualifying engine, exhaust, and fuel systems of dedicated AFVs and of refueling installations, subject to some constraints on total amounts allowed and phasing out after 2001. Two major issues appeared: (1) whether the depreciation benefit for dual-fueled vehicles should be based on the incremental cost of the qualifying systems, as in the Ways and Means amendment, or on total cost of these systems as intended by Representative Levin (CR, May 27, 1992: H3801) and Senator Rockefeller (S. 1178) and (2) whether electricity should qualify under refueling property.

The Senate Finance Committee marked up H.R. 776 on June 16, specifying (1) that the incremental cost of a dual-fuel light duty vehicle should be defined as no less than $1200 or if actually greater, no more than $2000, (2) that electrical recharging equipment should qualify as refueling property, but batteries would not, and (3) that electric vehicles (EVs) would be eligible for a 15% income tax credit. The net effect of the EV provision would be to bring EVs much closer to economic equivalence to other vehicles, while the greater incentive for dual-fueled vehicles would tend to make methanol, ethanol, and LPG dual-fueled vehicles economically attractive enough to appeal to some potential buyers not under mandate. The maximum for refueling property would be $75,000 compared to the House's $100,000. Otherwise, the provisions of the two chambers were the same.

Another Approach

Another new thrust affecting motor fuels came from Senator Jeffords (S. 716). This bill would mandate that a specified minimum percentage of motor fuels be produced from domestic nonpetroleum resources. In the early years of such a mandate, most would probably come from additives to gasoline such as ethanol and MTBE -- already going into gasoline in response to Clean Air Act requirements. S. 716 would affect the sources of methanol, butylenes, and ethers. In later years, alternative fuels (and perhaps synthetic fuels) would probably generate large portions of the domestic nonpetroleum content.

The Senate Committee on Energy and Natural Resources considered the S. 716 concept in its markup sessions on S. 341 in May 1991. It decided to charge DOE to develop a program to promote domestic nonpetroleum replacement and alternative fuels, to study the feasibility of setting a percentage goal, to follow the number of AFVs and FFVs likely to be sold, and to seek commitments from fuel producers to produce enough such fuels to supply the AFVs and FFVs in use.

As passed by the House, H.R. 776 included a provision setting a national goal of 10% replacement of gasolines and diesel fuel by 2000 and 30% by 2010, at least half of the replacement fuels being domestic, with the Department of Energy responsible for evaluating the practicability of achieving and developing appropriate programs to achieve these goals.

In floor debate on H.R. 776, Representative Jontz offered an amendment which would have specified the method to reach 10% replacement, by requiring that two octane numbers in gasoline be provided by domestic renewable components. Such a requirement equates to 10% ethanol. The amendment was defeated, 211-198.

The Conference Agreement

The Federal fleet purchase requirements common to both predecessor bills were retained. However, fuel use requirements were delayed somewhat (33% in 1997 to 75% in 1999 and later) to permit infrastructure development. The House version for State fleets prevailed.

For private fleets, alternative fuel vehicles would be required initially of fuel providers only (30% in 1996, rising to 90% in 1999), applicable only to the business units of the companies engaged in sale of alternative fuels. For other private companies and local governments, fleet purchase percentage goals phase in at 20% in 1999, rising to 70% in 2006 and later.

The Department of Energy (DOE) would be empowered to implement, modify, or waive these requirements under a 3-year rule-making process (1993-1996). Should DOE choose, as a result of this process, not to carry out a private fleet program, it would be required to undertake a second rule-making (1998-2000), this time to phase in fleet purchase goals starting at 20% in 2002, rising to 70% in 2005.

This agreement provides a leadership role in alternative fuel use to Federal and State governments and to fuel providers, to be followed, after time has provided an opportunity for lessons to be learned and technologies to be improved, by diffusion into general private fleets taking into consideration the lessons learned in the early years.

On the tax side, the House provisions (incremental costs only, for dual-fueled vehicles, plus the higher allowances for refueling property) prevailed, except that a tax credit for electric vehicles was retained from the Senate version (at 10% rather than the Senate's 15%).
