This letter will confirm that Northern Illinois Gas intends to provide a CNG tank trailer to be used for refueling the City of Elgins test program vehicles. The trailer has a usable capacity of approximately 54 equivalent gallons. Northern Illinois Gas personnel will transport and refill the trailer as required to conduct the evaluation. It is agreed that the test period will last four months and that there will be no charge to the city for use of the trailer. However, there will be a pickup and delivery charge to transport the trailer between Naperville and Elgin. The fee for this will be $25.00 per hour Portal-to-Portal. Additionally, the natural gas used will be charged to the city in accordance with our Rate 10 plus our gas supply charge which currently is 23.24 cents per therm. A copy of Rate 10 is enclosed. Also, Northern Illinois Gas will assist the City of Elgin in conducting economic analysis of the program and offer technical support in the conversion of the test vehicles. Please feel free to contact me if you have any questions or concerns regarding this project. Sincerely, Scot F. Koif General Engineer cc: F. Blazek D. Grote T.

En �OfEtc Agenda Item No. n �� July 17, 1991 MEMORANDUM TO: Mayor and Members of the City Council FROM: City Manager SUBJECT: Alternate Fuels PURPOSE: The intent herein is to solicit Council approval to proceed with a pilot program for the use of Compressed Natural Gas (CNG) . BACKGROUND: We are in an era that promises stricter clean air rules, especially regarding vehicle air quality standards. Amendments to the Clean Air Act suggest that 30% of all govern- mental fleets be converted to an alternate fuel by 1995 . The intent of these conversions will be to reduce air pollution, reduce dependency on foreign oil and lower fuel costs . The staff Alternate Fuels Task Force has researched various options such as Methanol, Propane, Ethanol and Com- pressed Natural Gas (CNG) . See attached memo dated 12-14-90 from Terry Podzimek, Garage Supervisor. The task force has narrowed the list of choices to CNG for numerous reasons such as price, availability, less pollution and safety. Accordingly, options have been considered whereby a pilot program can be established as a test sample for the entire City fleet of roughly 220 vehicles . Northern Illinois Gas (NI-Gas) was contacted and several meetings have transpired to date relative to supply and filling capabilities without the need of a compressor station. The two closest CNG equipment suppliers were contacted regarding vehi- cle conversions and service. During preliminary discussions with both suppliers it became readily apparent that Automotive Natural Gas, Inc. (ANGI ) in Milton, Wisconsin was much more interested in assisting the task force in developing the re- quirements for a pilot program than the other firm. In addi- tion to being responsive to City informational needs, ANGI is experienced in converting vehicles to CNG and has performed several conversions for NI-Gas . r , December 14, 1990 MEMORANDUM TO: Larry Rice, City Manager FROM: Terry Podzimek, Garage Manager SUBJECT: -Alternate Fuel Evaluation And Comparison PURPOSE: The intent of this memorandum is to provide information relative to the four (4) most popular alternate fuels and provide cost estimates for same. BACKGROUND: The four (4) fuels which will be analyzed are as follows: 1. Compressed Natural Gas (C.N.G. ) 2. Methanol 3. Propane - Liquified Petroleum Gas (L.P.G. ) 4. Ethanol . The pros and cons of each fuel will be discussed. Each fuel demonstrates various positive and negative characteristics. Approximate costs for conversions and cost/gallon and cost/mile factors will be discussed. The following characteristics are as compared to gasoline in a non-dedicated engine. • A. COMPRESSED NATURAL GAS (C.N.G. ) 1. ECONOMIC COMPETITIVENESS: Current cost for a gallon of gasoline is $1.22. Estimated cost for an equivalent gallon of natural gas is $. 62 - $.70. 2. AVAILABILITY: Surplus is estimated at a 35 - 50 year supply. Technology improvements could drastically increase that estimate. 3. REPRESENTATIVE TYPE OF FLEET: Light and heavy duty. Central refueling location ideal. 4. EXHAUST EMMISIONS: Nitrogen Oxides (NOx) - Same or higher Hydro carbons (HC) - Same or higher Carbon Monoxide (CO) - Lower Natural gas vehicles have no evaporative or running loss emissions and a small amount of refueling emissions. In diesel engines particulate matter (soot) is drastically reduced. The E.P.A. currently has no emissions standards for N.G.V. "s. • Alternate Fuels Page 3 the risk of accidental ignition. The methods of refueling are as follows: A. Outdoor Fast Fuel B. Outdoor Time Fuel C. Indoor Fast Fuel D. Indoor Time Fuel Time fuel is when vehicles are connected to a central hose bank at the end of the day and slowly refueled overnight. This method eliminates the need for auxiliary storage tanks at the refueling site, but still requires a compressor. This method usually takes eight (8) to ten (10) hours. Fast fuel is when the vehicle pulls up to a dispenser and refuels in three (3) to five (5) minutes, very much like an ordinary gasoline dispenser. This method also requires a compressor (to compress the natural gas to 3500 psi) and auxiliary storage tanks to supply already compressed gas for immediate refueling. 11. REFUELING INFRASTRUCTURE: Commercial refueling stations are in use through out the country. Currently there are 260 locations in 36 states with additional stations in the planning stages. One is being considered in Elgin. To purchase a refueling station for fueling city vehicles the cost is estimated at $42,000. This figure is an approximate cost dependent upon the number of vehicles to be fueled at once and the number of convenience •and safety options specified. There are more than 30,000 N.G.V"s in operation in the United States, with over 500,000 in service world wide. 12. RETURN INVESTMENT: It is estimated on a 200 vehicle fleet conversion, a five (5) percent return of the initial investment could be realized in approximately three years. B. METHANOL 1. ECONOMIC COMPETITIVENESS: Current cost for a gallon of gasoline is $1.22 per gallon. Estimated cost for a gallon of methanol is $1.57. 2. AVAILABILITY: Limited - Good future potential. Additional Methanol plants are entering production worldwide. 3. REPRESENTATIVE TYPE OF FLEET: Light and heavy duty with central refueling location. 4. EXHAUST EMISSIONS: Nitrogen Oxides (NOx) - Same or higher Hydro Carbons (HC) - Same or lower Carbon Monoxide (CO) - Lower Methanol emissions are very similiar to gasoline emissions. E.P.A. emission standards which take affect in 1991 are Alternate Fuels Page 5 C. PROPANE - LIQUIFIED PETROLEUM GAS (L_P_G. ) 1. ECONOMIC COMPETITIVENESS: Current city cost for a gallon of gasoline is $1.22 per gallon. Estimated cost for a equivalent gallon of propane is $1.75. Due to the fact propane is a by- product of crude oil refining, the cost of propane fluctuates with the cost of crude oil. 2. AVAILABILITY: Propane is the nations fourth largest energy source. It is produced by 250 gas and oil companies. Production estimates are predicted to be very good with supplies adequate into the year 2004. Eighty five percent of all propane used in the United `States is produced domestically thus reducing foreign dependancy. The remaining 15 percent is produced in Canada and Mexico. • 3. REPRESENTATIVE TYPE QF FLEET: Light and Medium Duty. Central refueling location. 4. EXHAUST EMISSIONS: Nitrogen Oxides (N0x) - Lower Hydro Carbons (HC) - Lower Carbon Monoxide (CO) - Lower Propane vehicles have no evaporative emissions due to the closed fuel system. Propane reduces emissions in vehicles both with and without emission controls. Currently the E.P.A. does not have emission standards for propane vehicles. 5. FUEL VOLUME: One and one half times the volume of propane is required to drive the same distance as a gallon of gasoline. 6. FUEL STORAGE CONTAINER WEIGHT: Since propane is not stored under extremely high pressures (350 psi) fuel storage container weight is only slightly heavier than a comparable gasoline tank. A typical propane tank would compare in weight to a typical diesel fuel tank. - 7. OPERATING CHARACTERISTICS: A. Driving Range: Approximately 10 percent less than gasoline. B. Performance: Five to Fifteen percent power loss. C. Cold Weather Starts: Better than gasoline. Propane enters the engine as a gas thus eliminating vaporizing problems, resulting in better starts. A well tuned engine is necessary to fully realize the benefits. D. Cold Engine Driveability: Better than gasoline - see above. E. Knock Resistance: Better than gasoline due to the 110 octane rating. 8. MAINTENANCE CHARACTERISTICS: A. Engine wear: Better than gasoline due to clean burning properties of propane. Carbon buildup is substantially Alternate Fuels Page 7 Carbon Monoxide (CO) - Lower Ethanol emissions are very similiar to gasoline emissions. E.P.A. emission standards are comparable to a conventionally fueled vehicle. 5. FUEL VOLUME: One and one half times the volume of ethanol is required to equal that of gasoline. 6. FUEL STORAGE CONTAINER WEIGHT: The same tank used for gasoline or diesel can be used for ethanol without any modifications, although to achieve the same driving range a larger tank is needed, thus increasing the weight. 7. OPERATING CHARACTERISTICS: A. Driving Range: Approximately 10 to 15 percent less than gasoline. B. Performance:, Power gain, but less than methanol. C. Cold Weather Starts: Worse than gasoline - usually vehicles are switched to ethanol once running. D. Cold Engine Driveability: Worse than gasoline due to poor vaporizing characteristics of ethanol. E. Knock Resistance: Better than gasoline due to 110 octane rating. 8. MAINTENANCE CHARACTERISTICS: A. Engine Wear: Worse than gasoline. Ethanol lacks the lubricating properties of gasoline or diesel. B. Maintenance Costs: Worse than gasoline. 9. CONVERSION COSTS: A. Cars and Pick-up Trucks - $500.00 B. Large trucks and buses - $1000.00 10. REFUELING PROCEDURE: Refueling of vehicles is identical to that of gasoline or diesel fueled vehicles. Ethanol can be stored in underground storage tanks. 11. REFUELING INFRASTRUCTURE: The existing infrastructure used for gasoline and diesel can be used for ethanol. Currently ethanol is used in gasoline in small quantities (ten percent) as an additive. 12. RETURN INVESTMENT: Unknown at this time. SUMMARY COMPARISON INFORMATION The following chart represent a summary comparison of the above discussed fuels. Additional areas are compared. The rating system is on a scale of 0 to 3 (0 signifying no concern, 3 high concern) . Alternate Fuels Page 9 initially, payback potential is greatly increased. All four alternate fuels demonstrate decreases in exhaust emissions. Full performance and emission benefits cannot be realized until the major automobile manufacturers develop a dedicated (designed specifically for an alternate fuel) engine. When this happens the full potential of a high octane fuel will be seen. The power loss, driving range, and mileage problems will be decreased or eliminated and exhaust emissions should be reduced even further. CONCLUSION: The Clean Air Act was signed November 15, 1990. It includes mandatory fleet conversion for government fleets. An incrementing percentage of all fleets (with ten or more vehicles up to 26,000 lb's G.V.W. ) will be required to be converted to an alternate fuel starting in 1998, and continuing thereafter. It is suggested the city proceed with C.N.G. as an alternate fuel source. The following alternatives should be considered: A. Convert all equipment. B. Convert a few pieces to analyze benefits. C. Invest in a refueling station: D. Rely on outside refueling source. Contact should be made with Northern Illinois Gas to ask for their aassistance in preparing a pilot program for fleet conversion.
