Adding 10% or 15% ethanol to gasoline causes a reactivity that leads to a 1 point increase in Reid Vapor Pressure, causing higher VOC's that will cause higher ozone pollution. Ozone is like acid to the lungs. This is the reason that the EPA has not given approval for E15 year round. Thousands of deaths are attributed to the waver already given to E10, why would anybody make the same mistake again knowing the deaths this waver has caused. The EPA needs to revoke the E10 waver and reduce the ozone danger to everybody. Every Environmental group is against the corn ethanol mandate. The EPA needs to stop this madness.
