1 City of Seattle CITY OF SEATTLE 2015 Biodiesel Implementation FINANCE AND ADMINISTRATIVE SERVICES

2 2015 Biodiesel Transition Green Fleet Feedstock Savings The 2014 Green Fleet Action Plan aims to reduce fleet GHG emissions by 42% by Transitioning to biodiesel is a central part of this strategy. Used cooking oil (UCO) is the city s feedstock of choice. By procuring a contract for biodiesel made from 100% UCO, the city ensured delivery of a high quality, BQ9000 certified product that met desired specifications. By choosing a robust, competitive reference price (Portland OPIS B5 SME) and going through a competitive bid process, the city received cost effective pricing that will save significantly over prices offered on the State contract. 2

6 Transition Plan June 2015 Phase 1: Wet Hose 284 vehicles over seven locations Controlled group of vehicles easily monitored /serviced should issues arise Fueled for two weeks prior to next phase Phase 2: Large Tanks Allow tanks to drop to 30% First delivery of B10 on Friday -closed over weekend Fuel polishing the following Monday Opened Tuesday - fueled for two weeks prior to next large tank transition Phase 3: Small Tanks Visually inspect/bacon bomb tanks Transitioned small tanks in weekly batches of seven Inspect fuel samples visually on a weekly basis for 1 month, then monthly thereafter 6

7 Quality Control Fuel testing Vendor drop samples taken for each fuel delivery and retains for 6 months for testing if necessary. Large tanks samples taken 1 week after each tank transition and visually inspected for quality issues in addition to regular on-going maintenance. Small tanks samples taken monthly and inspected for quality issues in addition to regular on-going maintenance. All UCO biodiesel is BQ9000 certified. Tank cleaning Fuel samples taken and visually inspected for all tanks 1 month before transition. Preliminary cleaning (water removal) was necessary at some site locations. Fuel polishing suggested in place of scrubbing walls of emptied tanks. Similar result for far less money and access was an issue at some sites. 7

8 Quality Control Cont d Vehicle fuel filters and tanks Vehicle fuel filters changed 1-3 weeks after transition. Vehicle fuel tanks visually inspected at and filters changed at each PM service during the first year of transition. Fuel site maintenance Dispenser nozzle filters changed one week after transition 2 micron pore size - and flow rate monitored closely for on-going timely filter replacement. Weekly/monthly site maintenance will continue as normal. Seasonal blends B10 November through February 4 months B20 March through October 8 months Biodiesel not used in stationary or low use equipment 8

9 Late October Update Going great! No complaints from drivers or maintenance staff New vendor has been responsive and easy to work with Lessons learned: Fuel polishing should be monitored and verified Bringing stakeholders into the process early is vital for robust plan Broad engagement helps others take ownership of the plan Use 2 micron filers on fuel dispensers and monitor flow rate 9
