Slide3: New Fuel Justification Fuel Specification Procurement Education Quality Management Compatibility of existing Infrastructure Tank Cleaning & Prep Storage Requirements Quantity Measurements Quality Measurement Long term quality Ordering Strategy Distribution DESC Fuel Introduction Process (Fuel Logistics) Acquisition Processes Handling & Storage Processes Quality Assurance & Forecasting ProcessesJustification of New Fuels: Justification of New Fuels Energy Policy Act (EPAct) 1992 EO 13149 DoD Strategy Established National Energy Policy Goals Towards Energy Security with provisions on Energy Conservation, Environmental Preservation, Petroleum Fuel Consumption, and Alternative Fuel Usage Established the Fleet Management Program which put stipulations on gasoline fuel consumption and introduction of alternative fuel vehicles Established DoD policy for procuring Alternative Fuel Vehicles and Alternative FuelsSlide5: What are the new fuels? Biodiesel Fuel (B100) Fuel Ethanol Mono alkyl esters of long chain fatty Acids made from vegetable oils and animal fats B20- 80% Diesel Fuel+ 20% Biodiesel Commerical Item Description A-A-59693 A Made from grain/feedstock products E85- 85% Fuel Ethanol+15% Gasoline Fuel Ethanol (Ed75-Ed85) ASTM-5798Slide6: How Do I Acquire Alternative Fuels from DESC? DESC buys fuel and energy products for both Military and Federal Civilian Agencies Slide7: What Should The Requirements Document Include? Location Current Point of Contact Projected Annual Usage (Gallons) Number & size of Tanks Preferred Method of Delivery Frequency of Deliveries At A Minimum:Slide8: How Does DESC Purchase Alternative Fuels? (e.g. B20, E85) DESC consolidates requirements by Geographic regions designated as Customer Organized Groups (COGs) Prepares solicitation packages and Advertises to potential suppliers Suppliers bid on the entire region or specific line itemsGround Fuels Division (DESC-PE/PL): Ground Fuels Division (DESC-PE/PL) Kathryn Riso x9511 Kathryn Riso x9511 Kathryn Riso, x9511 Kathryn Riso x9511 Tyler Parker, x9536 Vacant, x8461 Dave Peterson, x9510 Mark Jones, x9520 Kathryn Riso x9511 COGs- Customer Organized Groups & Corresponding Contracting Officers Slide10: Solicitation Package Contents Fuel Specifications Quality Assurance Provisions Quantity Measurements Delivery Requirements Points of Contact Informs potential suppliers of the terms and conditions for bidding including………………..Slide11: New Fuel Justification Fuel Specification Procurement Education Quality Management Compatibility of existing Infrastructure Tank Cleaning & Prep Storage Requirements Quantity Measurements Quality Measurement Long term quality Ordering Strategy Distribution DESC Fuel Introduction Process (Fuel Logistics) Acquisition Processes Handling & Storage Processes Quality Assurance & Forecasting ProcessesBiodiesel Properties: Biodiesel Properties Per Specification Clause C16.27 B20 Biodiesel (DESC Oct 2003) PRODUCT COMPOSITIONAL REQUIREMENTS 20% +/- 1% mono-alkyl esters of long chain fatty acids derived from virgin vegetable oil blend stock and/or yellow grease blend stock per ASTM D 6751. 80% minimum low sulfur diesel fuel oil conforming to ASTM D 975, grade low sulfur number 1-D or grade low sulfur number 2-D. SIGNIFICANT PRODUCT PERFORMANCE REQUIREMENTS 1. Appearance per ASTM D 4176 – Clear & Bright 2. Cloud Point Per ASTM D 2500(test) and ASTM D 975 (characteristics)Biodiesel Properties: Biodiesel Properties Per Specification Clause C16.27 B20 Biodiesel (DESC Oct 2003) PRODUCT LOW TEMPERATURE PERFORMANCE Lower temperature defined by 1 of the 2 properties: Cloud Pt, Cold Filter Plugging Point (CFPP) Cloud Point tested per ASTM D 2500 < or = 10th percentile minimum ambient temperature in the geographical area and seasonal timeframe in which the B20 is to be used, when tested per ASTM D 975 3. Max CFPP of the B20 shall be a minimum of 10 degrees Celsius below 10th percentile minimum ambient temperature in the geographical area and seasonal timeframe in which the B20 is to be used, when tested per ASTM D 6371Biodiesel Quality Assurance: Biodiesel Quality Assurance Techniques NOT permitted by DoD Specification Splash Tank Blending In Receipt Tanks Truck Manifold Blending Manifold Receipt Tank Receipt Tank NOTE: AFTER FIRST SHIPMENT OF BIODIESEL, FILTERS SHOULD BE CHECKED AND MAY NEED TO BE CHANGED DUE TO THE CLEANING CAPABILITIES OF THE BIODIESEL PRODUCT. Biodiesel Fuel Management: Biodiesel Fuel Management Fuel Tank Cleaning Requirements USE EXISTING DIESEL TANKS (1) DETERMINE AMOUNT OF WATER IN THE TANK WITH WATER FINDING PASTE. (2) LOOK AT WATER FINDING PASTE FOR ANY CLUMPS OF SLUDGE OR SEDIMENT AND FROM THIS, ESTIMATE LEVEL OF SLUDGE OR SEDIMENT IN THE BOTTOM OF THE TANK. (3) IF TANK DOES NOT CONTAIN MORE THAN 1/4 INCH OF WATER AND LESS THAN 1/2 INCH OF TOTAL WATER, SLUDGE AND SEDIMENT, THEN DRAW THE TANK DOWN AS LOW AS POSSIBLE AND REFILL WITH BIODIESEL. (4) IF WATER/SLUDGE/SEDIMENT LAYER IS GREATER THAN 1/2 INCH, ATTEMPT TO DRAIN AS MUCH AS POSSIBLE. IF IT CAN BE DRAINED TOTHE REQUIREMENTS IN 3 ABOVE, THEN DO SO. THEN DRAW THE TANK DOWN AS LOW AS POSSIBLE AND REFILL WITH BIODIESEL. (5) IF DRAINING CANNOT BE ACCOMPLISHED, THEN THE TANK SHOULD BE CLEANED BEFORE PUTTING BIODIESEL IN THE TANK.E85 Specifications: E85 Specifications ASTM D5798-99 Standard Specification for Fuel Ethanol (Ed75Ed85) For Automotive Spark-Ignition Engines Source: DOE: Handbook for Handling, Storing, and Dispensing E85 E85 Fuel Management: E85 Fuel Management Use of Existing Fueling Systems Many metal and fiberglass tanks which meet EPA codes, Dec. 98 are compatible with E85 In many cases, existing, gasoline, diesel, or other hydrocarbon fueling systems are suitable to store and dispense E85 Fiberglass tanks manufactured before 1992 MAY NOT able to store E85 Contaminated fuel is the most common source of operational problems with E85!!! Preparing Existing Fueling Systems DO NOT use plated steel tanks!!! Tank cleaning is required to remove gasoline particulates. The cleaning technique chosen will depend on the previous fuel stored and the condition of the tank!

DESC ground fuel customers receive fuels by 3 transportation modes: Transport Truck with meter Truck & Trailer with meter Tank Wagon (equipped with meter by default) Note: Quantity measurement and delivery conditions are defined in F1.01-1 “Delivery Conditions for Transport Trucks, Trucks and Trailers, and Tank Wagons” in DESC Ground Fuel Contracts. Government Determination Receiving government entity determines fuel quantity Meter measurement OR Weight (using calibrated scales) OR 3. Calibrated meter on receiving tank systemSlide20: How does the government determine the quantity of a fuel delivery? Note: Quantity measurement and delivery conditions are defined in F1.01-1 “Delivery Conditions for Transport Trucks, Trucks and Trailers, and Tank Wagons” in DESC Ground Fuel Contracts. Contractor Determination Contractor may determine fuel quantity by: Calibrated meter on the delivery conveyance OR Gauging the delivery conveyance OR Certified receiving tank markers OR 4. Load rack meter or calibrated scalesQuality Assurance Requirements: Quality Assurance Requirements Contractor Quality Activities Alternative Fuels are supplied under Posts, Camps and Stations (PC&S) FOB Destination Contracts Quality Assurance criteria and responsibilities are defined in E Clauses of the contract Contractors are responsible for having a Quality System and product Quality assurance including maintaining records, sampling and testing of productQuality Assurance Requirements: Quality Assurance Requirements Government Inspection and Acceptance are usually by receiving activities at destination Receiving locations should report delivery and quality problems to contracting officer and quality problems to DESC-BQ Contractor may be required to submit samples to government laboratory Government reserves right to perform quality inspections at all times Alternative fuels are commercial products and there is no government inspection at the vendor facilities Government Quality ActivitiesHandling & Storage Strategy: Handling & Storage Strategy Gasoline/ Ethanol Fuel (E85) Diesel/ Biodiesel (B20) Standard gasoline is refined or blended to be consumed with minimum storage time. Gasoline intended for extended storage requires additives which improve storage quality E85 is handled and stored in a manner consistent with Gasoline; however, Fuel operating equipment and materials should be evaluated for compatibility. Standard diesel fuel is also refined to be consumed With minimum storage time. Standard diesel fuel is blended with additives to improve cold temperature storage. Biodiesel fuel storage requirements are similar to those of standard diesel. Additives are available which can assist with storage and cold temperature handling Summary: Summary You should now know and understand…. You do not have the permission to view this presentation.
