U.S. Update

Federal - Energy Independence & Security Act of 2007

Renewable requirement for diesel must met by biodiesel 500 million gallons in 2009 1 billion gallons in 2012

U.S. House Extends Biodiesel Tax Incentive

Extends biodiesel tax incentive for 1 year through Dec. 31, 2009. Provides $1 per gallon incentive for all biodiesel regardless of feedstock. Shuts down the abusive "splash and dash" loophole that currently allows foreign produced fuel to enter the U.S, claim the biodiesel tax incentive, and be shipped to a third country for end use. Properly defines tax benefits available to co-processed renewable diesel. Waiting for Senate approval

California Differences & Special Regulatory Issues

California Petrodiesel B1-B5 B6-B19 B100 D975 D975 D975 D6751 Hawaii D975 No Spec No Spec D6751 Nevada D975 No Spec No Spec Other

California Biodiesel Specification

The Department of Food and Agriculture, Division of Measurement Standards, has adopted performance and drivability specifications for biodiesel fuel as follows: Biodiesel blending stock and biodiesel fuel blends must meet the specifications set forth by ASTM D975 for blended biodiesel and D6751 for pure biodiesel (B100). Additionally, blends of B5 or higher must display a sign on each dispenser that reads: "This fuel contains biodiesel. Check the owner's manual or with your engine manufacturer before using."

California - Executive Order

Issued by Gov. Schwarzenegger 04/25/2006

Executive Order that, among other things, establishes a target for the state of California to produce and use a minimum of its biofuels within California as follows: 20 percent by 2010 40 percent by 2020 75 percent by 2050 Biofuels includes both ethanol and biodiesel.

Biodiesel Blend Use Requirement San Francisco

The City of San Francisco mandated that diesel vehicles used by San Francisco's public agencies must use at least B20 blends by December 31, 2007. All departments were required to phase in B20 in incremental stages in 2007 to reach 100% use in all diesel vehicles and other diesel equipment.

Biofuels Procurement Preference Hawaii

Contracts for the purchase of diesel fuel are to be awarded with preference given to bids for biofuels or blends of biofuel and petroleum fuel. When purchasing fuel for use in diesel engines, the preference is $0.05 per gallon of B100; for blends containing both biodiesel and petroleumbased diesel, the preference is applied only to the biodiesel portion of the blend. Biodiesel must meet ASTM D6751 specification.

Fuel Quality Issues & ASTM Standards

BQ-9000 "Quality Assurance Program"

"Specifies requirements for a quality assurance program where an organization needs to demonstrate its ability to provide product that meets ASTM D 6751... and applicable regulatory requirements, and to address quality assurance through the effective application of the program..."

Helps ensure that end-user is getting high-quality biodiesel!

Fuel Quality


Fuel quality is of the utmost concern and importance to the biodiesel industry. ASTM D 6751 is the specification for biodiesel fuels regardless of the feedstock source and/or processing method. · National Quality Program (BQ-9000) launched for Biodiesel Marketers and Producers · Assures "cradle-to-grave" fuel quality

"cradle" "grave"


BQ-9000 Information Through the NBB

Find information on the requirements for the program and a list of accredited producers and marketers on the NBB website.

Quality Control

In 2006, 41% of B100 samples tested met ASTM D6751 specification In 2007, 89.6% of B100 samples tested met ASTM D6751 specification 100% of BQ-9000 certified fuel met ASTM D6751 specifications Currently, one third of production capacity is BQ-9000 Certified

Definition of Biodiesel

Biodiesel, n. -- a fuel comprised of monoalkyl esters of long chain fatty acids derived from vegetable oils or animal fats, designated B100, and meeting the requirements of ASTM D 6751. Straight Vegetable Oil is not biodiesel. Other biomass products are not biodiesel.

New ASTM Standards passed June 19, 2008

Filter Plugging Issues

Breakdown of Filter Plugging Sources

From April 2007 to March 2008 - Filter Plugging Problems Addressed by the National Biodiesel Hotline Microbial Only High Water and Microbial High Water Only Biodiesel Contaminants No problem Found Improper blending Other Oxidation, Oil Contaminants Biodiesel Didn't Meet Specification Outside Temperature Was Below Cloud Point ULSD Paraffin's 21% 18% 15% 10% 10% 8% 8% 5% 5% 3%

Microbial Growth

Several filters showed high content of live microbial organisms or a build-up of dead microbial material. The filters with microbial contamination often had an odor different from the normal fuel smell. MEG Corp believes that the lack of sulfur in biodiesel and ULSD aids in the build-up of such organisms since sulfur is a key component of many biocides and is a natural inhibitor of bacterial and fungal growth.

Treatment and Prevention


-Three major groups: Fuel soluble, Water soluble,

and Universally soluble. -Need to be EPA registered and compatible with the lubricant.

Preventing Fuel Contamination

- Preventing contamination from air and water requires proper tank maintenance and cleaning

Paraffin Wax

The material on these filters was solid until touched or warmed to room temperature, then it melted. Laboratory analysis showed this material was in fact paraffin/hydrocarbon in nature. The high level of paraffin material could be from the way ULSD is processed. When the temperature of the fuel is at or below its cloud point, paraffin material will precipitate out and collect on the bottom of the tank. As a point of note, when the heavy paraffin's are disturbed from the filters, they liquefy. The minor ingredients associated with biodiesel will not liquefy and require heat to go back into solution. Paraffin build-up does not come from biodiesel fuel.


Filters with a black and shiny surface but no microbial growth odor or gel or sediment indicate they may be plugged by oxidation build-up. Because many newer engines run at higher temperatures, there may be a black "asphaltene" type material collecting on the filter. This phenomenon has been seen all around the country, often in newer engines.


Hot Fuel Return

New Technology delivers the unused fuel from the engine block back to the fuel tank much faster. This hot fuel will cause degradation and oxidation of the fuel, which in turn can plug filters.



Coking Fuel

Monoglyceride Build-up

This filter tested positive for high concentrations of saturated monoglyceride material. Monoglyceride is one substance that can precipitate out of fuel if the glycerin levels are too high in the biodiesel used in the blend.

Terminal Blending

Terminal Blending

Biodiesel is added to a stream of diesel fuel as it travels through a pipe or hose in such as way that the biodiesel and diesel fuel become thoroughly mixed by the turbulence encountered in the pipe.

Other Blending Methods

Splash Blending ­ Biodiesel and diesel are loaded separately. Product mixes due to agitation during blending, transport and delivery. In-Tank Blending ­ Biodiesel and diesel are loaded separately or simultaneously at enough of a fill rate that fuels are sufficiently mixed without need for additional mixing or agitation.

Benefits of Terminal Blending

Preferred method of mixing biodiesel blends No added steps for trucks to load biodiesel Better accuracy of bio-blend percentages Better mixing in cold weather Blending documentation on a single bill of lading Movement towards biodiesel at the terminal ­ over 30 terminals nationwide
