Steps 5-6

Step 4

Steps 1-3


Appointing a Project Manager (like a fleet maintenance or hands-on person interested in biodiesel), then have them:

1. Read the Department of Energyʼs “Biodiesel Handling and Use Guidelines”

2. Reach out to fleet operators of biodiesel blends with similar fleet sizes and applications.

3. Require a D-6751 ASTM spec sheet from the distributor to ensure that your fuel has been tested to meet the most recent specifications.


Step 1: Educate Step 1

  Handling and Use

  Compatibility and Cost   High Blend Characteristics

•  Biodiesel Solvency

•  Cold Flow– Specify your feedstocks!

•  Microbial Growth

•  Oxidative Stability– Ask about additives

  Know your trucks and your people!


Step 2: Research Step 2

•  Clean ALL tanks and ALL storage •  Get the rubber OUT (Viton & Teflon) •  Review containment regulations and compliance •  Work hard for maintenance buy-in and create a solid maintenance schedule •  Apply a filtration system to at least 5 microns •  Use protocols to prevent contamination •  Create paper trails from supplier to end user You can be stopped by gelling, poor maintenance: clogged filters, dirty tanks and infected tanks– BUT NOT BY GOOD FUEL


Step 3: PLAN Step 3


Step 4: Contact Fuel Distributor   Visual inspection of quality operations- Permits and ethics?

  BQ 9000 equivalent program- Procedural compliance?

  Feedstock choices impact sustainability and cloud point

  Certificates of Analysis- Who does their COA? Lab on site?

  Availability– reliable producers?

  Customer service- reference check? Good paper trail?

  Cost history- Bulk discount levels?

  Location– transportation surcharges?

  Experience – years of distribution or production?

Step 4

  It is wise to start small– have your PROJECT MANAGER focus on logistics (feedstock control, producer/distributor relations, individual trucks, tanks, piping, filters, education)

  Individual engines/tanks may demonstrate different carbon deposit build-ups. Have spare parts on-hand, keep an eye on drips, & change oil

  To minimize the possibility of disturbance to your fleet systems apply lower blend levels at first to a few vehicles (if feasible) and work up as you and your fleet adjust to the new fuel

  Biodiesel is easy to phase in and out, so you can maintain flexibility in technology deployment

  Never let your guard down- feedstocks and producers do change


Step 5: Pilot Step 5

USE A FIELD TEST TO PRE-DETERMINE QUALITY Batch-specific samples of B100 for testing critical parameters, such as ʻBiodiesel Quality Status Reportʼ

Distributor has a quality program* that includes: 1. Acid Number/oxidative stability 2. Free and total Glycerin 3. Flash point 4. Cold Flow 5. Water and sediment

Fleet Manager has a quality program* that includes above & secure storage: 1. Remote sensor log 2. Sticking for water 3. Bacterial growth (filter changes) 4. Acid number (fuel degradation)

quality program*-- will vary by location, fleet, distributor, use, etc


Step 6

Step 6: Sampling

Everything from a broken headlight to a faulty alternator has been blamed on biodiesel. Without a strict record keeping regime, there is no means of documenting maintenance and cost impacts of biodiesel.

This can be especially effective if you have a solid record keeping system already in place. •  Biodiesel Program File

1.  Create a vehicle list in Excel 2.  Educational Resources 3.  Training and Quality Processes 4.  Check Lists

•  Infrastructure 1.  Create a tank list in Excel 2.  Tank drawings 3.  Tank History Bridging the Biodiesel Gap

Audit is intended to establish baseline of system and verify old tanks are clean for new good clean fuel before a fleet begins a B20 program

Step 7: Record Keeping Step 7

Have you taken step 1-7 again?

Approach pyramid again and review to be sure all elements from compatibility, storage and fueling are in place.

•  B5 pilot does not mean you are ready for B20.

•  B20 Pilot does not mean you are ready for B20 Fleet-wide.

•  B20 Fleet-wide does not mean you are ready for high blend levels. Bridging the Biodiesel Gap

Step 8: Go Fleet Wide Step 8

By diversifying your fueling sources and stabilizing prices, your company can save money and prepare for the future.

Beyond the economic advantages, many companies are finding that by doing the right thing for the environment, our national security, and vehicle performance they are directly benefiting from the marketing advantages of using biodiesel.

Stickers on vehicles, press releases about environmental responsibility, participation in industry panels, and leadership in the realm of sustainability all come with biodiesel use. Over 700 fleets currently use biodiesel or a biodiesel blend.

Your fleet can be next.


Step 9

Step 9: Market your Success


• Fuel and labor prices: It now costs nearly twice as much as a year ago to grow, harvest and ship commodities to Europe from the Gulf Coast of the U.S.

•  Dollar decline: Makes food imports more expensive at the store and creates greater demand for US agricultural exports.

• Trade restrictions: Major exporting countries are applying export taxes and/or bans on exports to control local prices, in effect reducing global supply.

• Increased food demand in developing countries: Diets are changing in countries like China and India, moving from starchy foods to meat and poultry. 10-16lbs of grain for one lb of meat.

• Climate change: Severe weather events (drought, heat, rain) in farming regions around the world have reduced harvests of cereal crops.

•  Speculators: have flocked onto commodity exchanges, pushing futures prices for grains above those that actual supply and demand would probably dictate.


Step 1

•  Limited petroleum supply

•  National energy security

•  Need to reduce greenhouse gas emissions

Step 1


Processing Technology is Continually being adapted for decentralized Rural and Urban Biomass production for fleets and distributors.

When sourcing your fuel begin looking for this local, sustainable optional and begin by inquiring with your local public and private utility operators. For example…

The San Francisco PUC launched the SFGreasecycle program to solve the problem of grease inappropriately being disposed of down the drain. By offering collection of all types of Fats, Oils and Grease (FOG) sufficient quantities are generated for local biofuel production, ultimately designated for the Public Fleet.

AB 32 and Carbon Share What the Carbon Share is: “In 2006 California passed the Global Warming Solutions Act (AB32), committing the state to reduce carbon dioxide emissions to 1990 levels by 2020. Cap and dividend is a simple, market based way to reduce CO2 emissions without reducing household incomes. It caps fossil fuel supplies, makes polluters pay, and returns the revenue to everyone equally. AB32 gave the California Air Resources Board (CARB) the authority to impose an economy -wide cap on state-wide greenhouse gas emissions

Regulated companies like fuel distributors and fleets will buy the shares and return it to the government agency.

Step 1


  EPA regulates Renewable Identification Numbers (RINs) to track compliance and volumes

  RINs MUST be tracked by Product Transfer Documents (PTDs) whenever change of ownership occurs

  For more information on creating and tracking: http://www.epa.gov/otaq/renewablefuels/index.htm

Step 1


You may save money in the end through reduced maintenance, improved marketing or diesel price fluctuations. You should ensure that you dedicate the initial funds and time for a smooth transition.

The transition to a biodiesel blend may include some upfront costs, such as a component compatibility review, that may save you money in the long run.

•  You may need to install or clean out a tank •  Dedicate employee training time •  Purchase filters, hoses, etc. for increased initial maintenance •  Be prepared to pay more or less for the blend


Compatibility and Cost Step 2

High Blend Characteristics (+) Lubricity 1% biodiesel replaces 65% of lacking lubricity of ULSD.

2% or higher totally replaces it = improved performance

Cetane # Higher cetane = improved combustibility – varies with feedstock

Safety in Handling Higher flash point and biodegradability= improved safety and handling

Less Smoke Less soot and toxics = reduction in plume and odor. B100 exhibits up to 47% decrease of particulates that carry the toxic chemicals resulting from combustion.

Quieter More complete combustion + lubricity = reduction of knocks and pings (noticeable at idle)

Lower Toxicity Absence of aromatics = reduced PAHs (cancer causing compounds)– Diesel has 20-25% aromatics


Step 2

High Blend Characteristics (-) Solvency Change fuel filter frequently as biodiesel will remove

accumulated deposits. Check fuel lines. Paint precautions.

Fuel Gelling B100 @ 20-55+º depending on feedstock; 0-25º for B20; recommend lower blends in winter

Microbial Growth More organically digestible by bacteria that commonly impact diesel systems

Elastomer, Pump and Seal Compatibility

Check compatibility/replace parts for engines prior to 1994

Oxidation Stability Donʼt store for long periods (6 months+) or expose to sunlight. Old fuel can become acidic and form sediments and varnish. Additives can retard this.

Energy Content 8% fewer BTUʼs per gallon, but also higher cetane #, lubricity, better combustion offsets lower BTU.


Step 2

Strong Solvency can (and will):

•  Lift sludge from tanks and lines i.e. fuel filter changing– change your filters after 2 days/months.

•  Can remove paint without cleaning

•  Degrade rubber parts- elastomer compatibility

•  Be confused with microbial growth or fuel quality– all of which can impact filter plugging

•  Pure biodiesel will dissolve asphalt– stop drips. Bridging the Biodiesel Gap

Step 2

Biodiesel Solvency


Sediments, bacterial slime, precipitates and free water can be trapped by filters along with any insoluble impurities associated with the fuel But…deteriorated fuel & acids can damage engines

Step 2

Biodiesel Solvency: Some problems get caught

Cold weather can cloud and even gel any diesel fuel, including biodiesel.

As of 2008, all ASTM biodiesel has been cold soak tested to help determine cold flow. In cold weather, a B20 will have a cloud point approximately 2 to 10° Fahrenheit.

•  cloud point- crystals are formed •  pour point- crystals impact flow •  cold filter plugging point- flow impacts filter

B20 has been used successfully in climates below -20ºF

Similar precautions employed for petroleum diesel in cold weather are needed for fueling with B20.

•  blending with #1 diesel (kerosene) •  using fuel heaters and parking indoors •  adding a cold-flow improvement additive


Step 2

Cold Flow- Fuel Gelling

Source: NRELʼs Biodiesel Handling and Use Guidelines


Step 2

Cold Flow- Fuel Gelling


•  Was the fuel exposed to cold temperatures?

•  Did it get cold and then warm up?

•  Cold flow is not Cold Filter Plug Point • 2-11 degree below Cloud point is estimated as your CFPP

•  Have you checked fuel (diesel and biodiesel) specifications?

•  When was your fuel produced?

•  Were additives blended? By whom?

Step 2

Water/fuel interface is where the bacteria lives. Monitor infrastructure regularly:

•  Stick the tank with modified water detecting paste • Sargel • Color Kut • Algae-X Test Kit (take sample for growth results) • Fleet Biodiesel Test Kit

•  Install desiccant filters for vents

Biocides are recommended for conventional and biodiesel fuels wherever biological growth in the fuel has been a problem. Biocides are toxic – use sparingly at recommended dosages. Eliminate all water from tanks.

If biological contamination is a problem, water contamination needs to be controlled at the fuel-water interface. Anaerobic colonies, usually sulfur reducing, can be active in sediments on tank surfaces and cause corrosion. Same biocides that work on diesel will work with biodiesel.


Microbial Growth Step 2


•  Have you tested for water?

•  Have you ensured this is not a sludge or cold flow issue?

•  Have you tested for microbial growth? • Field test kit • Lab analysis

•  Have you shocked your tank with biocides?

•  Increased filter changing intervals will be an indication of growth

Step 2

•  ASTM D6751 demands 3 hours minimal

•  Some distributors are concerned that the 3 hours is not enough because of excessive heat or prolonged storage by the end user.

•  Re-test for oxidative stability.

•  The biodiesel specification contains parameters for insuring adequate fuel stability for normal applications

•  The shelf life of biodiesel blends is recommended by NBB as 6 months unless the fuel is treated with additives and protected from water intrusion– in which case it can extend the shelf life.

Bridging the Biodiesel Gap 8/31/2008

Step 2


•  Have you checked the condition of you vehicle tank or storage tanks?

•  When have you checked fuel filters and tank filters?

•  Have you checked equipment compatibility? •  Tanks at Distributor and Fleet and vehicle? •  Hoses at Distributor and Fleet and vehicle?

•  Trace your fuel. Was the delivery method checked? •  Delivery tanker washed out? •  Did the tanker clean out? •  Tanks tested for water?

•  How long have you been using?

• Have you re-checked stability and water parameters as a rusty or contaminated tank can negatively impact these parameters easily?

Step 2


Mechanics can tell customers: “You got bad fuel” “We have to drain your tank” “Your fuel system is junked-up” “Your fuel pump should be changed”

All this means = CHANGE YOUR FUEL FILTER and see if that works first.

Mechanics push more expensive solutions often because fuel filter changing with regular diesel will not solve typical problems. They also donʼt understand how frequently fuel filters need to be changed, if they donʼt work with biodiesel– this is not a typical response. Mechanics tell customer: “Your fuel pump should be changed”– so clarify what is wrong with it.

Step 2


•  Is the elastomer in question listed as a known biodiesel compatible material?

•  Have you checked all transfer hoses and tanks for fuel residues that was put in the tank/hose/pump prior to biodiesel?

•  Is there evidence of sediment or rust particles in your tank?

•  When was your fuel produced? How was it stored? Was it exposed to heat?

•  Have you re-tested for oxidation stability? Did the fuel contain anti-oxidants? Is this dose documented?

Seals leaking? Or are mechanics of it failing? Are the vehicle or transfer hoses hard? Soft?

See NBB “Materials Compatibility”

Step 2


•  Identify the date of the first symptom •  Go back to your samples •  Hire a Consultant to analyze the Blend samples. •  Pull samples from the storage tank –send to consultant/ laboratory for analysis. •  Review your Blend Sheets from the date of the first issue •  Review the COA (Certificate of Analysis) from your Supplier –send to the consultant/laboratory •  Construct a Work Plan to solve your Customerʼs issue.

When quality standards fail and customer concerns grow. What do you do?

Step 2



  Biodiesel is electrically conductive = more corrosive

  Biodiesel can oxidize: producing corrosive peroxides

  Solvents can degrade elastomers

  Biodiesel effects may be slow to appear –important to system designers and testing organizations

  Biodiesel can exhibit counterintuitive blend level effects

  Biodiesel can be more aggressive when water contaminated

  Biodiesel can be more aggressive in acidic conditions

  Biodiesel can be more aggressive with age Alternative Fuels Lead UST Section/Division of Water Quality State Water Resources Control Board Sacramento, California, February 2008


Compatibility Precautions Step 3

  Avoid vulnerable metals (Copper, Brass, Lead, Zinc, Tin )

  Avoid off-spec fuel, water, and “old” fuel

  Insist on guarantee of ASTM D6751 fuel quality

  Ask polymer manufacturers for advice

  Select UST system components tested at > 500 hours exposure

  Ask supplier for “Rancimat” test certification on each fuel drop

  Keep everything free of water Robert Hodam, MSE, MBA Alternative Fuels Lead UST Section/Division of Water Quality State Water Resources Control Board Sacramento, California, February 2008


Step 3

•  NO DIFFERENT THAN DIESEL

•  Dispose of rags properly-

•  Tied into flash point (gasoline is the worst)

•  Rag service

•  Dispose in air tight or water filled

•  Oiled rags can spontaneously combust


Step 3

Absorbent/Rags

Precaution: Biodiesel is electrically conductive inferring it induces greater corrosion.

Update: Biodiesel is slightly more conductive than diesel. However, the difference is not great enough to induce noticeable corrosion increase. This was proven by the research published by the Steel Tank Institute. Additives are often added to diesel to make it more conductive to reduce fire hazard. Corrosion is not a concern due to electrical conductance in diesel or biodiesel.


Biodiesel Compatibility Step 3

Precaution: Biodiesel can oxidize: producing corrosive peroxides.

Update: Recent ASTM Biodiesel specifications ensure that oxidation stability and acid number are sufficient to avoid these concerns.

When biodiesel oxidation does occur, the peroxides formed are nothing like H202 that is normally considered peroxide.

Peroxides, however, are the first step in oxidation and will lead to fuel deterioration through polymer formation and acids.


Step 3

Biodiesel Compatibility

Precaution: Biodiesel has frequently been out of spec and contaminated with corrosives.

Update: Fuel quality has been a persistent problem in the last several years. While the initial National Renewable Energy Laboratory survey on quality indicated perhaps 50%* of biodiesel on the market place was out of specification, the current survey published by NREL in March 2008 reported over 90% of biodiesel nationwide meets ASTM D-6751

ASTM compliance through enforcement of existing state and federal fuel quality regulations should always be a priority.


Step 3


Precaution: Water contamination makes biodiesel more aggressive.

Update: Water contamination is a problem for any fuel. Free water is extremely corrosive . Dissolved phase water, in turn, can increase the conductivity of the fuel, diesel or biodiesel-- and therefore accelerate electrolysis.


Step 3


Precaution: Acidic conditions make biodiesel more aggressive to some polymers.

Update: Acidic contaminants are controlled in Biodiesel fuel quality by measuring Total Acid Number (TAN) . The ASTM specification for TAN is 0.5 mg KOH/g . The national average acid number is 0.3 mg KOH/g.

These low acid values means these fuels are non-aggressive with respect to acid content. However, oxidized biodiesel (out of specification) can form acids over time in the presence of heat, moisture, bacteria and metal ions.

Biodiesel which meets the legal requirement to meet the ASTM specification is not aggressive to most polymers, although always confirm compatibility with the manufacturers.


Step 3


Precaution: Biodiesel may degrade elastomers cured using metal oxides.

Update: This formulation is the only formulation to present elastomeric swelling, and is the one on which based all previous suppositions. We believe it has no implications for UST systems operating at ambient temperatures.



Precaution: Changes in elastomeric properties may be delayed.

Update: While this is true on certain elastomers, long-term durability tests referenced from a recent DuPont study were carried out at 125 degrees C.

This well exceeds the temperatures experienced by UST systems, and this failure mode does not occur at lower temperatures.

To extrapolate this accelerated test to real world conditions would equate to 3 or 4 decades of trouble-free use at ambient storage temperatures and normal engine operation temperatures.



Precaution: Aging makes biodiesel more aggressive.

Update: DuPont data that was conducted at extreme conditions not subjected to by UST systems.

Specifics were not given as to what properties of the biodiesel changed due to aging for this experiment.

The ASTM specification includes oxidative stability as a requirement, so the properties of biodiesel remain constant during its useable shelf-life.

It is presumed that this “aged” biodiesel exceeded some ASTM parameter such as oxidation stability, acid number and water and sediment.


Step 3



Field reports indicated a cleaning effect is still a possibility even with the B5 blends, especially if your fuel storage and handling systems are old or have not been carefully maintained.

Depending on the condition and age of your fueling infrastructure, you should clean any fuel tanks that will store biodiesel to remove any build up of sediment before transitioning to biodiesel or a biodiesel blend.

Develop a tank management quality program for your site to ascertain the ongoing status of your fuel and tanks. Take regular bottom samples to verify lack of moisture content and microbial activity. Depending on how quickly you use the fuel an additive may be recommended.

Maintain dry tanks and insist on dry fuel


Tanks and Storage Step 3

•  What Tank? ALL TANKS!

•  Distributor UST? •  Delivery Tanker? •  Your Storage tank(s)? •  Vehicle Tank?

•  Storage tank materials include: Aluminum, steel, fluorinated polyethylene, Fiberglass, fluorinated polypropylene and Teflon

•  Must meet local requirements for diesel storage

• Should not be stored over 6 months without precautions: •  Testing regularly •  Additives may be used for prolonged storage •  Fuel Rotation- drain and use fuel every 6 months

•  See NBB “Materials Compatibility”


Step 3

1)  Ideally use a wet/dry stinger to clean tanks Do this now to pay off later:

•  less fuel filter changes •  Less down time •  Less maintenance costs •  May lose contaminated fuel •  May have to do this later anyway

2)  Invest in Bacon Bomb/sample thief to sample bottom of tank for contaminants regularly

3)  Sump pump and wet/dry vacuum

4)  Keep it clean: regular cleaning, changing filters and desiccant filter on top.

Clean to the bottom! Clean means clean!


Step 3

Clean Your Tanks

Usually your 2” rain cap can be replaced with a desiccant filter. Note: Commonly used in moist environments: •  Size appropriately for air flow rate during fuel delivery •  Size for appropriate desiccant filter changing intervals, ideally change annually (check with manufacturer)


Step 3

Tank Breathers

  Federal Trade Commission's (FTC) fines of up to $11,000/day for non-compliance

  Labels must be on pumps by Dec. 16, 2008

  6%-20% biodiesel or biomass-based diesel, retailers can either specify the exact blend being vended or can opt for more general language

  Above 20%, the exact blend ratio is required

  For biodiesel, the label will be blue and appear as "BXX"

  The rule doesn't require labels for pumps with 5% or less of either biodiesel blends or biomass-based diesel

  For more information, visit www.ftc.gov


Retailers must Label! Step 3


  ASTM spec fuel that is improperly stored, transported and handled can go out of specification

  Observed distribution problems include:   Storage tanks contaminated with water or bad fuel

(ULSD or B20); bacteria slime builds in tank and eventually released by biodiesel

  Trucks not clean; carry over residues to fuel   Improper techniques for blending and fueling   Aged fuel – oxidized, precipitates, sediments   Mixed batches of fuel from various suppliers

Step 3

Biodiesel Storage: Fuel Quality Can Deteriorate

Is switching from petroleum diesel to a biodiesel blend considered a change of stored substance?

“Yes. When any percentage of biodiesel is added to an UST system that has been permitted to store petroleum diesel fuel, it is considered a change of stored substance. California Code of Regulations, Title 23, section 2711 requires the UST owner or operator to inform the local regulatory agency of the hazardous substances that are stored, or are proposed to be stored, in the UST system. Section 2711 also requires the owner or operator to notify the local agency of any changes to that information within thirty days unless required to obtain approval before making the change. We strongly advise local regulatory agencies to require notification from the UST owner/operator PRIOR to any change of stored substance. This will allow the local agency to determine ahead of time whether or not the UST system is suitable for storing the new substance.”

California EPA Kevin L. Graves, P.E. Underground Storage Tank Program Manager February 28, 2008


Step 3

California Biodiesel Storage



  pHlip test   Color change- reject fuel (purple= alkaline = soap or methanol or catalyst and

yellow= acidic = old= not stable)   Interface between two layers (no third layer, ideally a mirror surface– although this

takes time and higher temps)

  Confirm the Basics   Oxidative Stability: Can change easily and should be confirmed after leaving your

producer   Water: Because of Biodieselʼs ability to attract and hold water, this parameter should

be checked and confirmed after leaving your producer

  Make decision to take/reject fuel   Spill containment- between tanker and hose and between hose and storage tank   Filter- to at least 10 micron into storage tank (pressure cage is better than not

watching speed flow decrease to determine filter clogging)   Watch for overflow of storage tank

Step 4


  Sample-do independent 3rd party testing for (at least partial) ASTM D-6751

  COA (Certificate of Analysis)- required before delivery and at time of delivery   Total Glycerin- how much below .24 is it? Even .2 may raise eyebrows   Stability test- When was it performed and is 3 hours enough?   Cloud point- checking your summer and winter parameters

  1 Visual test-- Clarity- can you read a newspaper behind your fuel?   Cloud Point- Get to know your cloud point and check temp of liquid   May be glycerides, but may be lack of filtering or non-compatible   May be a sign of moisture   May be a sign of soaps   If not clear, keep draining out tank until you get the sample you want to see. If you go

beyond 10 gallons, the whole lot is likely bad   Compare feedstocks– changes dramatically (even canola that is not bleached my be

green)

Step 4


DISTRIBUTOR TRAINING - Comprises information for the purchase and transferring for resale of biodiesel in bulk quantities.

California Air Resources Board, H&S 43026 Definition of "Motor Vehicle Fuel Distributor"

For purposes of this section, "motor vehicle fuel distributor" means any person who (1) refines, blends, or otherwise produces motor vehicle fuel, or (2) with an ownership interest in the fuel, transports or causes the transport of motor vehicle fuel at any point between a production or import facility and a retail outlet, or sells, offers for sale, or supplies motor vehicle fuel to motor vehicle fuel retailers.

Step 4


To successfully sell biodiesel, the operational characteristics and physical properties of the fuel need to be understood to be able to adequately address customers concerns and requests. After achieving an in depth understanding of what biodiesel is and how it operates in diesel engines, the next steps are to implement biodiesel as another fuel product for sale.

The most important item is the quality of the incoming biodiesel purchased. Different than diesel, protective measures must be maintained to preserve the integrity of the product at each stage of storage, blending and delivery. A Biodiesel Quality Manual should be used as a process management tool that details each step in the distribution chain of the product. In general, this manual will help create the process for getting good quality biodiesel in and checking the quality right as it is sold through a Biodiesel Status Report.

Step 4


Quality Manual Programs

The National Biodiesel Board (NBB) www.nbb.org has an industry standard program for both Biodiesel Marketers or Distributors and Producers. The BQ-9000 Quality Management Program brings an industry standard approach and provides updated information and developing best management practices.

“The National Biodiesel Accreditation Program is a cooperative and voluntary program for the accreditation of producers and marketers of biodiesel fuel called BQ-9000. The program is a unique combination of the ASTM standard for biodiesel, ASTM D 6751, and a quality systems program that includes storage, sampling, testing, blending, shipping, distribution, and fuel management practices. “

More information at www.bq-9000.org

Step 4


Purchasing Incoming fuel purchased for distribution must be carefully selected and screened for ongoing quality verification. One bad batch of fuel can cause significant problems for you and your customer. Fuel quality is a constant variable and producers must have adequate manufacturing technology and extensive fuel testing capabilities. Producers must consistently provide quality fuel and be able to provide their own quality management procedures.

Require documentation: •  (certificate of analysis) COA •  Previous (bill of lading) BOL

Step 4

  Tank cleaning– same issues as above

  Contamination with other petroleum products (i.e gasoline, engine oils)

  Oxidized diesel fuel– can be demonstrated by black slimy material in filter or in tanks

  Blending– can you count?

  Equipment compatibility? Part of hoses?

  Not filtering properly

  Retail station must filter to 5 micron (not very much)

  RINs: basic currency for the RFS program for credits, trading, and use by obligated parties and renewable fuel exporters to demonstrate compliance, as well as track the volumes of renewable fuels

  “New Holland, has approved the use of 20 percent B20 in all of its equipment using New Holland engines.” (www.newholland.com)

  “John Deere is a strong advocate for the production and use of biodiesel fuel. Developing alternative, renewable energy is good for the consumer, the environment, and the American farmer.” (www.deere.com)

  “Cummins Inc. today (March 20, 2007) announced the approval of biodiesel B20 blends for use in its 2002 and later emissions-compliant ISX, ISM, ISL, ISC and ISB engines. This includes the recently released 2007 products.” (www.cummins.com/)

  “Case IH equipment globally is leaving the factory with a biodiesel blend in the tank. And, all Case IH engines are warranted for approved B5 blends and most engines are warranted up to the B20 level.” (www.caseih.com)

OEM Statements


Step 5

  Caterpillar has a “Tiered biodiesel blend approval structure based on equipment type and model.” (www.cat.com)

  “GM currently approves the use of certified biodiesel blends of up to 5% (B5 blend biodiesel) in its 2006 Duramax engine sold in the U.S., and is aggressively researching the use of 20% mix for its future diesel models.” (www.gm.com)

  “Any recent-model Ford truck with a diesel engine can run on a mixture including up to 5 percent biodiesel (B5) . . . Ford is working with researchers and other partners to develop a biodiesel fuel that will allow utilization of at least 20 percent biodiesel (B20) in future diesel vehicles.” (www.fleet.ford.com/)

  International will warranty engines using up to and including the B5 blend. Association (EMA). International's warranty policy does not deny coverage solely for the use of blends higher than B5, but only if the failure is attributed to the use of higher biodiesel blends. (www.internationaldelivers.com/)

OEM – Current issues


Step 5

Blue-tech technologies keeps B20 warranty issues:   Chrysler/dodge/sprinter– 2009   Mercedes thinks it will be ok?

Volkswagen: Post injection of fuel which is diluting engine oil because the flashpoint of biodiesel is higher, therefore not burning completely and condensing into engine oil

Engine oil needs to be low soot-- specific to post combustion fuel technologies (canʼt be Rotella)

All major U.S. OEMs support B5 and lower blends, provided they are made with biodiesel meeting ASTM D 6751, the existing ASTM International standard for pure biodiesel (B100)

Many are progressing toward support for B20 pending approval of a new ASTM standard for B20 blends

Use of blends higher than B5 will not necessarily void existing warranties

Step 5

“Itʼs a no-brainer to use biodiesel,” . . . By using the biodiesel weʼve eliminated the particulate and the big black plume. Weʼre doing good for the environment and weʼre reducing our petroleum use by 20 percent.” Arlington Countyʼs fleet of biodiesel-fueled vehicles is approximately 350 vehicles, which includes 125 school buses, all its heavy trucks, and all its construction equipment. “Our operators really donʼt notice a difference,”

-- Ric Hiller - Bureau Chief, Arlington County Virginia

“There is much less smoke at the B20 level and both the mechanics and bus drivers have noted the difference, not to mention the kids.” Hettler tracked statistics like the time the buses idle, the miles per hour they drive, oil analysis, and the mileage the buses get.

-- Wayne Hettler, Garage Foreman & Head, Mechanic Michigan school district


Municipalities Using Biodiesel Step 5

April, 2008 Denver's Department of Public Works began using B20 in 2004 during a pilot program. Since then, the city has gradually increased its biodiesel use and now fuels the city's entire diesel fleet of approximately 1,000 vehicles and equipment with B20. That does not include Denver International Airport, which also uses B20.

In Colorado Springs, the diesel fleet of more than 2,400 vehicles and equipment runs on B20. In fact, Colorado Springs has been recognized as a national leader in the effort to utilize cleaner-burning biodiesel in its fleet. The city was recently named the top municipal biodiesel fleet in the nation by Government Fleet Magazine.

Since Colorado Springs first began using B20 in 2003, the city has made a significant contribution to environmental protection. As of early 2008, the city had used 1.6 million gallons of B20. City officials estimate that this amount is equivalent to 500 vehicles not being driven for one year, or a reduction of over five million pounds of carbon dioxide being released into the atmosphere.”

-- Denver Post



August, 2007 “The City of Kingsport has been looking into using biodiesel for some time and got started about six months ago when they began putting B5 in their 1,000 gallon tank at the cityʼs landfill. About 10 pieces of equipment used the B5 there.

In April they moved the blend up to B20. As things went well during that trial phase, city Assistant Manager David Light decided to approach city council about moving the rest of the fleet to biodiesel.

“They were supportive,” says Light of that meeting. “It was then that we made plans to move our main fueling center 10,000-gallon underground tank to B5. Weʼve been on B5 for about two months now and we plan to ramp up to B20 over the next nine or so months. So far we have not had any major problems – some fuel filter change-outs, but nothing else.”

-- Assistant Manager, David Light

"I never used diesel-fired pressure washers before because I didn't like diesel fumes, but biodiesel fumes are pleasant and food grade. . . I'm not doing it as a feel-good thing--I want to make a better product.”

-- Jim Klein, Winemaker “This (biodiesel) replaces the solvent that we have to pay to get replaced every three months, and this other microbial cleaner we tried that's a hazard to dispose of. The biodiesel is so much cheaper--we can use the same 5 gallons for months. And it's safer. It's not flammable.”

Biodiesel Integration Process

At Coast Oil, biodiesel is embraced as an overall fantastic and flexible product that works really well especially in blended form. Biodiesel offers our customers options not only in environmental effects, but economical as well when biodiesel costs are lower than regular diesel. By offering competitive pricing on various consistent high quality blends, their customers can save by having fuel choices. For Coast Oil, this means good product growth and expanded business.


Step 5

To accommodate the quality concerns of their customers, Coast Oil has integrated a BQ-9000 Quality Management System.

Distributor: Coast Oil

“As soon as we made a transition to Biodiesel , 3 of our subcontractors transitioned as well!!” “ Our demolition and debris business has served the Bay Area for over 20 years and have a wide range of modern equipment running on B99.9 biodiesel - from large dump trucks, dump trailers, pick-up trucks, bobcats. Cleaner burning biodiesel provides a healthier work environment for our staff and our clients. We exclusively purchase biodiesel made from 100% recycled vegetable oil to ensure we are engaged in sustainable business practices. -- Paul Sonnabend and David Sherman, Owners


Construction: Hurricane Hauling & Demolition Inc.

Step 5


Distributor has a sampling program that includes quality: 1. Acid Number 2. Free and total Glycerin 3. Flash point 4. Water (Note: May want to send to local testing laboratory for low cost testing) Batch-specific samples of B100 for testing critical parameters, such as ʻBiodiesel Quality Status Reportʼ

Fleet Manager has a sampling program that includes above & secure storage: 1. Water 2. Remote sensor log 3. Sticking for water 4. Bacterial growth (filter changes) 5. Acid number (fuel degradation) 6. D 7371 (%Bio)– “rancimat”


Step 6

Sampling

  Complete Reaction – avoid partially reacted fuel!

  Removal of Glycerin – residues accumulate in engine

  Removal of Catalyst – destroys gaskets and seals

  Removal of Alcohol – lowers flash point of fuel

  Absence of Free Fatty Acids – aged, oxidized fuel


Distributor and fleet managers should be aware of basic principles of biodiesel handling:

Step 6


 Residues in storage tanks, filters and lines  Clogged dispenser filters, then bus filters  Dissolved contaminants foul injectors  Coking of injectors and varnish on valves  Rough engine operation, smoke, wear  Crankcase oil deterioration, polymerization   Long term or catastrophic engine damage

Step 6

Anticipating and Avoiding Fuel Problems Associated with Deteriorated B20 Fuel


  Biocides can inhibit growth of bacteria and mold when traces of water contaminate fuel – common problem in storage tanks, particularly in humid climates

  Maintain seals and gaskets on caps and steel lids over the fill pipe sump

  Pump fill pipe sump; never let it drain into tank

  Monitor, monitor, monitor; Polish fuel regularly

  Filtration of fuel to at least 3 microns

  Fuel “polished” (filtered to remove water and sediment) as required

Step 6

More on additives and techniques

1. Each Distributor may recommend varying additives:

•  Stabilizer-Prevents Oxidation (Ketone) •  Winterized Fuel •  Bug-Out –Prevents Algae and Bacteria •  Anti-Gel -to “0”F. •  Dehazer –Disperses Entrained Water

2. Fleet Manager should verify quantities and compatibility of any additives that are added by producer or distributor.

3. Additional additives may be required


Step 6

Additives



Step 7

  Certification   Transportation   Storage   Quality Sampling   Biodiesel Blending


 Certification of Analysis – Producers full verification of ASTM standards when sampled properly provide proof of biodiesel quality. Be sure to request this upon transfer of product.

 Field Testing – spot testing for drivers and trained biodiesel managers to read and record. Several industry examples include pHlip tests and

 Third Party Laboratory Analysis - for certain parameters (BQSR) report. This report is important for understanding the key properties that are sensitive to change. Verification of quality after time and transportation is essential to make sure that the fuel still meets ASTM requirements.

 See the sample BQSR report in the resource folder for more information.

Step 7


Transportation Previous Bill of Lading for the bulk material that was on the vehicle just prior to biodiesel loading. This is particularly important for distributor fleets that transfer gasoline too. Verifying Diesel was transported prior provides proof that gasoline or bulk lubricating oils were not mixed. Even the small amount of gasoline will increase the flash point beyond acceptable ranges.

See the Tank Truck Inspection Form in the Resource folder for more information.

Step 7


Storage – Use tanks that only are compatible and have been inspected for integrity. Testing for the same parameters as the BQSR is recommended.

Baseline Analysis testing of the tanks monthly provide verification that stratification and/or oxidation is occurring.

Quarterly Analysis may be done when there is a stable rotation of fuel from known producers. This analysis will verify that the fuel is not changing in storage and that off product was not received.

Step 7


Step 7

Biodiesel Quality Sampling

Purchase BQSR Report – ensures the biodiesel integrity

Storage Tank BQSR Report - ensures biodiesel is stable in storage

Blending Analysis Tests – ensures biodiesel is blended appropriately Some customers may periodically require sampling to occur at the point of delivery. This fuel can be tested for the blend percentage to verify fuel integrity and billing details.

Sample Retention – compatible storage jars in an environmentally appropriate storage area for at least 60 days Samples must be labeled with lot number, date, tank, and operator that connect to purchasing and customer records. This connects the sample and test results to the original raw materials and production batches.


Record must be kept of biodiesel purchase receipts, lot number, and quantity received, producer origin and storage tanks.

Sufficient organization of the related documents such that retained samples can be identified with the relevant COA, previous Bill of Ladings, Blending Worksheets, BQSR reports and Tank Truck inspection forms that contain identification and tracking information that references customerʼs order numbers.

In summary: At time of delivery Customer gets CoA, BQSR, previous BoL and Truck Inspection Forms for rail car unloading and delivery vehicle, Blending worksheet, storage tank BQSR, and copy of Distributors Quality Control Management Program.
