2. By Way of Introduction • Vandenberg AFB consists of 98,000 acres & is the 3rd largest Air Force base in U.S.; • Accessed by approximately 520 miles of roads; • Estimated 2004 base population 9,836 personnel: • 32% military personnel; • 33% military dependents; • 14% federal civil employees; & • 21% contractor employees

3. E-85 Dispensing Facility • One dispenser with a 10,000 gallon UST; • Phase I and II Emission Vapor Recovery (uncertified); • Dedicated electronic user key assures E-85 use for applicable vehicles; • Services approximately 137 government owned vehicles (2004 inventory): • 92 of 118 Light Duty Autos • Remainder fueled by gasoline (25) & CNG (1) • 19 of 75 Light Duty Trucks • Remainder fueled by gasoline • 26 of 101 Medium Duty Trucks • Remainder fueled by gasoline (55) & CNG (20)

4. Construction • Upgrades to the Military Vehicle Fueling Facility included the installation of an E-85 dispenser, nozzles, hoses, breakaways, drop tubes, piping and uncertified Phase I & II EVR equipment.

7. Operations • Initial year (2004) averaged 3,425 gallons per month (Start up Dec 2003);

8. Operations • 2005 averaged 6,905 gallons per month

9. Regulatory Requirements • Quarterly testing to assure operation & compliance • Quarterly & Annual reporting to SBCAPCD • Quarterly & Annual reporting to CARB • Throughput limits: 1.2 million gal/yr • Emission limits: 4.17 lbs/day; 0.76 T/yr

10. Quarterly Testing Requirements • TP-201.1B – Static Torque of Rotatable Phase I Adaptors • TP-201.1C – Pressure Integrity of Drop Tube/Drain Valve Assembly • TP-201.1E – Leak Rate and Cracking Pressure of Relief Valves • TP-201.3 – Static Pressure Performance Determination • TP-201.4 – Dynamic Back Pressure & Liquid Removal Note: TP-201.6 – Liquid Removal Rate Determination • Determined not applicable in Jan ‘04

11. Regulatory Status of the Facility • 03 Mar 03 – CARB approves facility as an R&D site; • 09 Jul 03 – SBCAPCD issues Authority to Construct 11023; • 09 Dec 03 – Facility begins initial operations; • 16 Apr 04 – SBCAPCD issues Permit to Operate 11023; • 18 Mar 05 – CARB approves two-year extension for facility to operate as a R&D site until 01 Apr 07.

12. The Way Ahead • Updated Equipment List due to CARB by 01 Apr 06; • No modifications to the equipment to date; • CARB certification remains an issue • throughput requirements and location of the facility; • Once certification process begins, VAFB to will acquire approval from applicable CA agencies • e.g., measurements, fire, and occupational health; • High percentage blends (> 10%; E-10) of ethanol remain unclear as to AQ impact • Agreed upon emission factors are still under development for higher blends such as E-85; • Vandenberg AFB is motivated, in part, by complying with Presidential Executive Order 13149 • 20% fossil fuel use reduction (1999 baseline) at federal facilities
