EPA Finalizes 2013 Renewable Fuel Standards to Help Promote American Energy Independence, Reduce Carbon Pollution
EPA also announces steps to address concerns about the E10 blend wall
WASHINGTON – As part of an ongoing effort to enhance energy security and reduce carbon pollution, the U.S. Environmental Protection Agency (EPA) today finalized the 2013 percentage standards for four fuel categories that are part of the Renewable Fuel Standard (RFS) program established by Congress. Most of these fuels are produced by American farmers and growers domestically and help reduce the carbon pollution that contributes to climate change.
The final 2013 overall volumes and standards require 16.55 billion gallons of renewable fuels to be blended into the U.S.fuel supply (a 9.74 percent blend). This standard specifically requires:
• Biomass-based diesel (1.28 billion gallons; 1.13 percent)
• Advanced biofuels (2.75 billion gallons; 1.62 percent)
• Cellulosic biofuels (6.00 million gallons; 0.004 percent)
These standards reflect EPA’s updated production projections, which are informed by extensive engagement with industry and a thorough assessment of the biofuels market.
During this rulemaking, EPA received comments from a number of stakeholders concerning the “E10 blend wall.” Projected to occur in 2014, the “E10 blend wall” refers to the difficulty in incorporating ethanol into the fuel supply at volumes exceeding those achieved by the sale of nearly all gasoline as E10. Most gasoline sold in the U.S. today is E10. In the rule issued today, EPA is announcing that it will propose to use flexibilities in the RFS statute to reduce both the advanced biofuel and total renewable volumes in the forthcoming 2014 RFS volume requirement proposal.
EPA is also providing greater lead time and flexibility in complying with the 2013 volume requirements by extending the deadline to comply with the 2013 standards by four months, to June 30, 2014.
A January 2013 ruling by the U.S. Court of Appeals required the agency to reevaluate projections for cellulosic biofuel to reflect market conditions; the final 2013 standard for cellulosic biofuel announced today was developed in a manner consistent with the approach outlined in that ruling.
The Energy Independence and Security Act (EISA) established the RFS program and the annual renewable fuel volume targets, which steadily increase to an overall level of 36 billion gallons in 2022. To achieve these volumes, EPA calculates a percentage-based standard for the following year. Based on the standard, each refiner and importer determines the minimum volume of renewable fuel that it must ensure is used in its transportation fuel.

Proterra All Electric Bus Visits CT DOT
![]() |
| Proterra EcoRide™ BE35 is an all electric bus. |
Newington, CT – Today at the Connecticut Department of Transportation Office, a new type of bus was shown and test driven. The Proterra EcoRide™ BE35 is an all electric bus. It will be expanding its public service this year to six transit authorities. It has already been in use for about a year now at Foothill Transit in the San Gabriel Valley northeast of Los Angeles, and it has been featured on Jay Leno’s Garage channel. Also the Worcester (MA) Regional Transit Authority will receive three transit buses along with the on-route charging station provided by a $4.4-million Federal Transit Authority Clean Fuels grant.
Proterra’s on-route fast charge system allows the bus to “automatically connect to an overhead system that links the bus to a high-capacity charger without driver involvement. The bus is then rapidly charged in 5-10 minutes while passengers load and unload,” as stated on the company’s website.
The composite body of the bus reduces the weight of the bus by 20-40% of a traditional steel or aluminum transit bus while still being crash and element resistant meaning more batteries can be added without going over weight. The battery cells sit on the bottom of the bus to give even weight distribution and a low center of gravity.
The ride on the bus was very quiet. The noise only noise came from the air conditioner’s compressor, which the company says they are working to reduce that noise as well. There was absolutely no diesel smell, in fact, one rider said “it has a new car smell.”
The bus is the first of its kind to pass the rigorous testing of the Altoona Bus Research and Testing Center. “The technology is proven; out company is performing and winning orders as a result,” says Garrett Mikita, president and CEO of Proterra, Greenville, SC.

CT Clean Cities Future Fuels Update
Greater New Haven Clean Cities was awarded an American Recovery and Reinvestment Act (ARRA) grant. The grant included $13.1 million in federal funding through the U.S. Department of Energy and $16.6 million in non-federal funds provided by over 30 partner organizations. The collaboration will lead to development and implementation of a state-wide fuel neutral effort that will deploy 267 alternative fuel vehicles (AFVs) and 5 public access and 5 private fleet access fueling stations as part of the Connecticut Clean Cities Future Fuels Project. You can learn more at the project’s website, http://www.ct-futurefuels.com/.
If you are interested in finding out more about what alternative fuels are best for your fleet visit http://www.afdc.energy.gov/ or email Lee Grannis at grannis@nhcleancities.org.
Below are graphs and charts that illustrate the Connecticut Clean Cities Future Fuel results as of June 30, 2013.
The project consists of 7 compressed natural gas (CNG) stations of which 4 are public access stations and 3 are fleet only access stations, 1 liquefied natural gas (LNG) with CNG station where the LNG side is fleet only access, but the CNG is public access, 1 fleet only access biodiesel station of B20, and electric charging stations with 4 as public use and 4 for fleet only use.
The graph above illustrates how much fuel was used by vehicles that were obtained as part of the project and fuel used by vehicles that companies outside of the project purchased because it made economic sense to do so. This graph shows that businesses are finding it beneficial to switch their fleet from traditional petroleum fuel to alternative fuels. Below are the numbers as to the number and type of vehicles obtained through the project.
The graph below gives the number of miles driven by in project vehicles by quarter. Thus far in the project over 20.2 million miles have been driven by these alternative fuel vehicles.

July 2013 Question of the Month
Question of the Month: What are the key terms to know when discussing natural gas vehicles (NGVs) and their fueling infrastructure?
Answer: As with all alternative fuels, it is important to know how to “talk the talk” when it comes to natural gas. Becoming familiar with the terms below will help you better understand NGVs and the associated fueling infrastructure, so that you can ask the right questions and make informed decisions:
Fuel Types
Vehicle Types
Fuel Measurement and Characteristics
Station Components
CNG Infrastructure Types
Additional information on natural gas production and distribution, NGVs, and natural gas infrastructure can be found on the Alternative Fuel Data Center website. The NGVAmerica website also provides a wealth of information on natural gas and NGVs.

| Enviro Express of Bridgeport, CT build a L/CNG station where they fuel their natural gas vehicles. |
Answer: As with all alternative fuels, it is important to know how to “talk the talk” when it comes to natural gas. Becoming familiar with the terms below will help you better understand NGVs and the associated fueling infrastructure, so that you can ask the right questions and make informed decisions:
Fuel Types
- Compressed Natural Gas (CNG): CNG is one of two forms of natural gas used to power vehicles. CNG is a gaseous fuel stored in a cylinder on the vehicle at a high pressure (see “psi” below). It may be kept in the vehicle cylinder for long periods of time without venting. A CNG vehicle gets about the same fuel economy as a conventional gasoline vehicle on a gasoline gallon equivalent basis (see “GGE” below). CNG is used in light-, medium-, and heavy-duty vehicle applications.
- Liquefied Natural Gas (LNG): LNG is produced by super-cooling natural gas to negative 260°F in order to convert it to a liquid. The fuel is stored in a double-walled, vacuum-sealed pressure vessel. LNG is appropriate for trucks and other heavy-duty applications that require a long range because liquid is more dense than gas (CNG) and more energy can be stored by volume in the vehicle’s tank. LNG stored in a vehicle will increase in temperature and pressure over time and vent; therefore, LNG should be used within a week or two of fueling.
- Renewable Natural Gas (RNG): Also known as biogas or biomethane, this emerging fuel source is derived from decaying organic materials, such as waste from plants, landfills, wastewater, and livestock. After purification, RNG may be compressed or liquefied to fuel vehicles.
Vehicle Types
![]() |
| The Town of Glastonbury has CNG light duty vehicles that they fuel at their own CNG station. |
- Natural Gas Vehicle (NGV): There are three different types of NGVs available:
- Dedicated Vehicle: Dedicated vehicles are designed to run only on natural gas and are used in both light-duty and heavy-duty applications. In general, dedicated NGVs demonstrate better performance and have lower emissions than bi-fuel vehicles (see below).
- Bi-fuel Vehicle: These vehicles are able to run on either natural gas or gasoline because they have two separate fueling systems. Bi-fuel vehicles are typically light-duty models.
- Dual-fuel Vehicle: These vehicles are traditionally used in heavy-duty applications and have fuel systems that run on natural gas, but use diesel fuel for ignition.
Fuel Measurement and Characteristics
- CNG and LNG may be measured in:
- Gasoline Gallon Equivalents (GGE): A unit of measure that represents the quantity of fuel that contains the same amount of energy as one gallon of gasoline. Measuring fuel in GGEs is a good way of comparing natural gas to gasoline, particularly when looking at fuel price or range. A GGE is equal to about 5.66 pounds of CNG and 1.55 gallons of LNG.
- Diesel Gallon Equivalent (DGE): A unit of measure that represents the quantity of fuel that contains the same amount of energy as one gallon of diesel. A DGE is equal to about 6.34 pounds of CNG and 1.72 gallons of LNG.
- CNG is also measured in:
- Cubic feet (ft3): CNG is a gas, so it may be measured by volume. MCF represents 1,000 cubic feet.
- Pounds (lbs.): CNG may also be measured in mass. Approximately 21 cubic feet of CNG equals one pound.
- LNG is also measured in gallons, much like gasoline or diesel.
- Pounds per Square Inch (psi): Psi is a measurement of the CNG pressure when it is stored in a dispenser or vehicle cylinder. CNG is typically stored onboard a vehicle at a pressure of 3,000 to 3,600 psi. The vehicle psi rating is important because it indicates the psi that the fuel system, vehicle cylinder, and the safety hardware are capable of handling safely.
Station Components
- CNG stations have the following components:
- Compressor: The device used to compress CNG to a high pressure.
- Storage Tank: Once the gas is compressed, the CNG is moved to storage vessel(s) or tank(s) specially designed for the fuel.
- Temperature Compensation: The temperature of CNG is important because it affects the density and energy per unit volume of the fuel. At higher temperatures, CNG expands and becomes less dense, causing it to contain less energy per unit volume as it would at a lower temperature. The temperature compensation devices ensure that the CNG is delivered to the vehicle at the appropriate temperature.
- Dispenser: The device used to transfer CNG into a vehicle’s tank. A CNG typically dispenser displays the pressure and temperature at which the tank is being filled and then calculates the amount of fuel being delivered.
- LNG stations also have storage tanks and dispensers, but do not require a compressor or temperature compensation devices.
CNG Infrastructure Types
- The following are two different types of CNG infrastructure:
- Fast-fill: Drivers fueling their vehicles at a fast-fill station can fill up in approximately the same amount of time as a conventional vehicle at a gasoline or diesel station. This set-up is best suited for retail stations, where vehicles arrive in need of a quick fill, and CNG can be dispensed alongside gasoline or other fuel dispensers. Fast-fill stations receive low-pressure fuel from the local utility line and employ a compressor on site. Once compressed, the CNG is stored at high pressures so it can be delivered quickly to a vehicle. As such, fast-fill stations may have smaller compressors but a larger storage capacity than time-fill stations.
- Time-fill: At a time-fill station, a vehicle may take several minutes to many hours to fill up; the time depends on the number of vehicles fueling, compressor size, and storage. Time-fill stations are typically used for fleets with central refueling locations or private stations that allow vehicles to fill up overnight. Time-fill stations can also work for smaller applications, such as residential fueling infrastructure. The fuel is also drawn from a local utility line into a compressor on site. Time-fill stations may have larger compressors and the vehicles are generally filled directly from the compressor, not from fuel stored in tanks. Time-fill stations have an advantage over fast-fill stations in that their heat of recompression is less so that vehicles at these stations usually get a fuller tank of fuel than with fast-fill.
Additional information on natural gas production and distribution, NGVs, and natural gas infrastructure can be found on the Alternative Fuel Data Center website. The NGVAmerica website also provides a wealth of information on natural gas and NGVs.

June 2013 Question of the Month
Question of the Month: What are the requirements for state and alternative fuel provider fleets under the Energy Policy Act of 1992 (EPAct 1992) and subsequent regulations and directives?
Answer:
EPAct 1992 mandates that certain state government and alternative fuel provider fleets in the United States acquire specified percentages of alternative fuel vehicles (AFVs) on an annual basis as they add light-duty vehicles (LDVs) to their fleets. Below we have described a number of means beyond simply acquiring AFVs by which these fleets may achieve compliance.
The U.S. Department of Energy (DOE) is responsible for overseeing compliance with these requirements, which were promulgated and published at 10 CFR Part 490 as the Alternative Fuel Transportation Program. Information about state and alternative fuel provider “covered fleets” (fleets subject to EPAct 1992 requirements) and the requirements associated with this compliance program are outlined below for each fleet type.
State Fleets
Covered Fleets
State government (including state agency and state university) fleets are considered covered fleets if all of the following conditions are met:
The following resources may be used to determine whether a state fleet is covered:
Requirement
Like federal fleets regulated under EPAct 1992, a covered state fleet must acquire in a model year the number of AFVs that is equal to at least 75% of the fleet’s non-excluded LDV acquisitions.
Compliance Methods
Covered state fleets may meet their requirements using multiple means through one of two compliance methods:
For a summary of compliance methods, visit the following website: http://www1.eere.energy.gov/vehiclesandfuels/epact/compliance_methods.html.
Inclusion of Hybrid Electric and Plug-in Electric Vehicles
Currently, all-electric vehicles (EVs) and some plug-in hybrid electric vehicles (PHEVs) qualify as AFVs under Standard Compliance. DOE published a notice of proposed rulemaking in October 2011, pursuant to Section 133 of the Energy Independence and Security Act of 2007, that would allocate AFV credits for covered fleet acquisitions of the following vehicles:
For more information on this proposed rulemaking, please see the proposed rule fact sheet (http://www1.eere.energy.gov/vehiclesandfuels/epact/pdfs/section_133_proposed_rule.pdf) and the full notice (http://www.gpo.gov/fdsys/pkg/FR-2011-10-31/pdf/2011-26761.pdf).
Alternative Fuel Provider Fleets
Covered Fleets
A covered alternative fuel provider is any entity that meets one of the following conditions:
An alternative fuel provider is not covered if its principal business involves:
In addition to meeting this definition, alternative fuel provider fleets are also subject to the same conditions for inclusion as state fleets (see above). For example, if a fleet does not own, operate, lease, or otherwise control at least 50 non-excluded LDVs, then it is not considered a covered fleet.
The Decision Tree for Alternative Fuel Provider Fleets (http://www1.eere.energy.gov/vehiclesandfuels/epact/alt_decision_tree.html) may be used to determine whether an alternative fuel provider fleet is covered.
Requirement
A covered alternative fuel provider fleet must acquire in a model year the number of AFVs that is equal to at least 90% of the fleet’s non-excluded LDV acquisitions.
Compliance Methods
Covered alternative fuel provider fleets have the same options for achieving compliance as state fleets.
Additional information on state and alternative fuel provider requirements and compliance options, as well the annual reporting requirements, may be found on DOE’s EPAct Transportation Regulatory Activities website (http://www1.eere.energy.gov/vehiclesandfuels/epact/index.html). In addition, the online Clean Cities University course on Understanding EPAct-Regulated Fleets (http://www1.eere.energy.gov/cleancities/toolbox/university.html) provides an overview of state and alternative fuel provider requirements.

State Fleets
Covered Fleets
State government (including state agency and state university) fleets are considered covered fleets if all of the following conditions are met:
- They own, operate, lease, or otherwise control 50 or more light-duty vehicles (LDVs; vehicles with a gross vehicle weight rating of 8,500 pounds or less) within the United States and are not on the list of excluded vehicles. Excluded vehicles include emergency, law enforcement, and non-road vehicles;
- At least 20 of those vehicles are used primarily within a single metropolitan statistical area (MSA)/consolidated MSA (CMSA), based on 1980 census data. A list of covered MSA/CMSAs can be found online: https://www.afdc.energy.gov/vehiclesandfuels/epact/state/progs/dyn_msa.cgi; and
- Those same 20 vehicles are centrally fueled or capable of being centrally fueled, meaning they are capable of being fueled at least 75% of the time at a location that is owned, operated, or controlled by the fleet or is under contract with that fleet for fueling purposes.
The following resources may be used to determine whether a state fleet is covered:
- Decision Tree for State Government Fleets: http://www1.eere.energy.gov/vehiclesandfuels/epact/state_decision_tree.html
- State Government Fleet Compliance with the Energy Policy Act of 1992: Self-Audit Procedures: http://www1.eere.energy.gov/vehiclesandfuels/epact/pdfs/selfaudit_procedures.pdf
Requirement
Like federal fleets regulated under EPAct 1992, a covered state fleet must acquire in a model year the number of AFVs that is equal to at least 75% of the fleet’s non-excluded LDV acquisitions.
Compliance Methods
Covered state fleets may meet their requirements using multiple means through one of two compliance methods:
- Standard Compliance: Fleets can acquire the requisite number of new or used AFVs, convert conventional vehicles to run on an alternative fuel within four months of acquisition, or obtain AFV credits from other covered fleets. Covered fleets earn one credit for each light-duty AFV that is acquired beyond the fleet’s annual requirement for the model year. Credits earned by going beyond compliance are banked for future use. Credits may also be traded with other fleets. Covered fleets may also meet up to 50% of their AFV-acquisition requirements by purchasing biodiesel blends of at least B20 for use in medium- and heavy-duty vehicles. One credit toward compliance is earned for every 450 gallons of neat biodiesel (B100) or every 2,250 gallons of B20 purchased for use. Credits earned for biodiesel purchase for use may not be banked. In addition, a fleet may earn credits for its medium- and heavy-duty AFV acquisitions, but only after the fleet has met its light-duty AFV acquisition requirements.
- Alternative Compliance: Covered fleets may obtain a waiver from the AFV acquisition requirements of Standard Compliance by submitting and then implementing a DOE- approved plan to reduce the fleet’s annual petroleum consumption. The plan must result in petroleum reductions equal to what the fleet would have achieved if all its AFVs were running on alternative fuel all the time. The plan must also include a sufficient level of data and information to support the fleet’s compliance requirements, particularly information on fuel use. Alternative Compliance petroleum reduction methods include, among others, hybrid electric vehicle (HEV) use, alternative fuel use, reduction in vehicle miles traveled, idle-time reduction, and truck stop electrification.
For a summary of compliance methods, visit the following website: http://www1.eere.energy.gov/vehiclesandfuels/epact/compliance_methods.html.
Inclusion of Hybrid Electric and Plug-in Electric Vehicles
Currently, all-electric vehicles (EVs) and some plug-in hybrid electric vehicles (PHEVs) qualify as AFVs under Standard Compliance. DOE published a notice of proposed rulemaking in October 2011, pursuant to Section 133 of the Energy Independence and Security Act of 2007, that would allocate AFV credits for covered fleet acquisitions of the following vehicles:
- HEVs would receive one-half credit
- PHEVs (those that do not already meet the definition of an AFV) would receive one-half credit
- Fuel cell electric vehicles (those that do not already meet the definition of an AFV) would receive one-half credit
- Neighborhood electric vehicles would receive one-fourth credit
For more information on this proposed rulemaking, please see the proposed rule fact sheet (http://www1.eere.energy.gov/vehiclesandfuels/epact/pdfs/section_133_proposed_rule.pdf) and the full notice (http://www.gpo.gov/fdsys/pkg/FR-2011-10-31/pdf/2011-26761.pdf).
Alternative Fuel Provider Fleets
Covered Fleets
A covered alternative fuel provider is any entity that meets one of the following conditions:
- The entity’s principle business involves producing, storing, refining, processing, transporting, distributing, importing, or selling any alternative fuel (other than electricity);
- The entity’s principle business involves generating, transmitting, importing, or selling electricity at wholesale or retail; or
- The entity produces, imports, or produces and imports in combination, an average of 50,000 barrels per day or more of petroleum, and 30% or more of its gross annual revenues are derived from producing alternative fuels.
An alternative fuel provider is not covered if its principal business involves:
- Transforming alternative fuels into products that are not alternative fuels; or
- Using alternative fuel as a feedstock, or fuel, in the manufacturing of products that are not alternative fuels.
In addition to meeting this definition, alternative fuel provider fleets are also subject to the same conditions for inclusion as state fleets (see above). For example, if a fleet does not own, operate, lease, or otherwise control at least 50 non-excluded LDVs, then it is not considered a covered fleet.
The Decision Tree for Alternative Fuel Provider Fleets (http://www1.eere.energy.gov/vehiclesandfuels/epact/alt_decision_tree.html) may be used to determine whether an alternative fuel provider fleet is covered.

April 2013 Question of the Month
Question of the Month: What are the federal emissions and fuel economy standards for current and future on-road vehicles? Have any related emissions and fuel regulations been passed recently?
Answer: Corporate Average Fuel Economy (CAFE) standards and the associated greenhouse gas (GHG) emissions standards set requirements for new light-, medium-, and heavy-duty vehicle models with the goal of improving the overall fuel efficiency and environmental impact. Fuel economy standards for light-duty vehicles were introduced in the Energy Policy and Conservation Act (EPCA) of 1975; regulations were established for on-road vehicles beginning with Model Year (MY) 1978. EPCA grants the U.S. Department of Transportation's National Highway Traffic Safety Administration (NHTSA) the authority to regulate CAFE standards, with the requirement that new standards may not be proposed more than five model years at a time.
In 2010, NHTSA partnered with the U.S. Environmental Protection Agency (EPA) to issue the first joint program that includes both fuel economy requirements under NHTSA’s CAFE program and emissions standards under EPA’s GHG emissions program. Starting with MY 2012 vehicles, manufacturers are required to improve fleet-wide fuel economy and reduce fleet-wide GHG emissions by approximately 5% each year. By 2016, vehicles must meet an estimated combined average emissions level of no more than 250 grams of carbon dioxide per mile. If the industry met this carbon dioxide standard solely through fuel economy improvements, vehicles would have an average fuel economy of 35.5 miles per gallon (mpg). For more information, see the EPA fact sheet:
NHTSA and EPA established the CAFE and GHG emissions standards for MY 2017 through MY 2025 passenger cars and light-duty trucks in 2012 in two phases, which are broken down as follows:
Model Years
|
Average Fleet-Wide Fuel Economy
| |
Phase 1
|
MY 2017-MY 2021
|
40.3-41.0 mpg (by MY 2021)
|
Phase 2*
|
MY 2022-MY 2025
|
48.7-49.7 mpg (by MY 2025)
|
*Proposed, pending final rule
For more information, refer to the EPA fact sheet.
In 2011, NHTSA and EPA set the first-ever standards to reduce GHG emissions and improve fuel efficiency of medium- and heavy-duty vehicles (vehicles with a gross vehicle weight rating greater than 10,000 pounds). The standards cover MY 2014 through MY 2018 on-road vehicles and are tailored to each of three main regulatory subcategories:
· Combination tractors (also known as semi trucks);
· Heavy-duty pickup trucks and vans; and
· Vocational vehicles (such as delivery, refuse, and tow trucks; transit, shuttle, and school buses; and emergency vehicles).
The requirements provide flexibility through an emissions and fuel consumption credit system to help reduce the overall costs of the program and to allow manufacturers time to make necessary technological improvements.
For more information on fuel economy and GHG emissions standards, refer to the NHTSA CAFE – Fuel Economy, EPA Transportation and Climate, andFuelEconomy.gov websites.
On March 29, 2013, EPA announced their Tier 3 Vehicle Emission and Fuel Standards Program, which includes more stringent tailpipe emissions standards for non-methane organic gas (NMOG), nitrogen oxides (NOx), and particulate matter (PM); more stringent evaporative vehicle emissions; and lower sulfur content of gasoline. This proposal aligns vehicle standards with the GHG emissions standards outlined above, as well as the California Low Emission Vehicle Program, allowing automakers to sell the same vehicle models in every state. The standards would apply to light-duty trucks, medium-duty passenger vehicles, and some heavy-duty vehicles and include different phase-in schedules based on vehicle class from MY 2017 to MY 2025. The proposed gasoline sulfur standard would make emission control systems more effective for both existing and new vehicles. For more information, refer to the proposed rule and the EPA Tier 3 Vehicle Emission and Fuel Standards Program website.
For more up-to-date information about federal and state vehicle standards, refer to the Alternative Fuels Data Center (AFDC) Federal Incentives and Laws website.
