1.Bio-diesel is safe, biodegradable, and reduces serious air pollutants such as soot, particulates, carbon monoxide, hydrocarbons and air toxins. Bio-Diesel acts like a detergent additive, loosening and dissolving sediments. Bio-diesel is also a superior lubricant. 2.We feel the improvements in emissions, reduction in odor and quieter operation of diesel powered vehicles/equipment will offset any cost difference in the fuel. Why Does the City of Brooklyn Park Use Bio-diesel?

Bio-Diesel Today Six Years Later We are: –Still using B-20 now & into 2008 –One of the first in the State to use Bio-Diesel for all diesel equipment in the fleet (100 vehicles ) –Blending B-20 with half #1 diesel & half #2 diesel for Winter Months (Artic blend) –Have always bought Biodiesel Standard (ASTM D 6751) American Society for Testing and Materials (ASTM) product(s) from a reliable vender

Biodiesel is an alternative fuel produced from vegetable oils or animal fats. Pure Bio-diesel contains no petroleum and yet is miscible with petrodiesel fuels. Bio-diesel has been shown to increase the lubricating qualities of the fuel. Biodiesel is a renewable fuel that is produced in the United States and it’s use helps reduce dependence on overseas oil imports. Biodiesel burns cleaner than petroleum diesel. Using Bio-diesel lessens exposure to harmful emissions that we breathe working around or riding in diesel powered vehicles/equipment. Minnesota has passed a law that states B-2 will come into use when two things occur; 8 million gallons of biodiesel must be in place and, secondly a federal or state tax credit of 2 to 3 cents per gallon must be in place, or June 30 th 2005 is reached. (Rochester and Albert Lea Plants opened!) There is nothing for mechanics or drivers to change when using B-20 or B-5. There have been observed no lubricity or gelling problems and no complaints from drivers or mechanics. To date the city has not found a “down side to the product, B-20 or B-5. Because B-20 or B-5 is better for the environment, is a natural lubricant and a renewable resource, in the long run it is a better investment for the city to use. The city intends to continue looking at all options available to our fleet of vehicles/equipment to best serve the citizens of our city. We will work closely with others to develop “win – win” strategies placing us in the forefront of technology. Conclusions and Recommendations
