This was intended to allow local agencies to respond to the call by making changes in operational behavior designed to reduce volatile organic compounds. Additionally, the local governments provided information to the citizens through local cable programming and signs in public buildings. There were 9 missed calls. In order to capture all high ozone days with an advisory in the future, the Division will be required to err on the conservative side and potentially over-predict. Given the closeness of the region to violating the ozone standard, the Division has indicated that they may have to call more red days next summer.
Historical data is provided in several tables .
The refiners agreed to make the reduction from Memorial Day through Labor Day. The APCD staff randomly sampled the fuel at metro area gasoline stations and reported that the average RVP was approximately 8.15 psi. It is assumed that this level provided at least the 0.5 psi reduction anticipated. One source of the hydrocarbons that contributes to ozone is spilled and evaporated fuel. By eliminating the overfilling of the fuel tank, small fuel spills, drips and excess evaporation are eliminated.
