The Dripless Nozzle Saving the Environment One Drop at a Time Matthew D. Millard

“The Air Is Cleaner, But Not Clean Enough” CARB  Cars Pollute 90% less now than in 1970  Zero-emission vehicles actually exist  Keep businesses that pollute in check  Vapor Recovery system I and II  Enforced liquid retention in hoses maximum  Enforced Post-Fueling Drips From Nozzle (3 drops maximum)

The Problem

NO POST FILL DROPS!! Valve Open Opens from Minor Back Pressure Valve Closed The Solution…A Dripless Valve

Environmental Impact  132,086 gallons/Year Spilled  Significant VOC Source  Toxicological Risk  Water Contamination  Over $500,000/year 22 Spilled Semi Trucks National Defense Center for Energy and Environment

The Future Is in Your Hands  California Needs Enforced Dripless Valves, just as it needed vapor recovery, zero emission vehicles, etc.  CARB is the only entity that can help. Thank you for your time Matthew D. Millard UCSD Inorganic Chemistry Ph.D. candidate Cell

Generation I Dripless Valve

Generation II

Solution is to STOP THE DRIP Not put a requirement on how many Tp-201.2D (Post-Fueling Drips From Nozzles)
