Code Orange Days To Rise With New Standards

Environmental officials are expecting an increase this summer in the number of ozone action days as a result of the change in Federal regulations governing ground-level ozone. The Clean Air outreach coordinator for the Baltimore Metropolitan Council, Russ Ulrich, says the new rules slightly reduce the allowable ozone content in the air before a declaration of Code Orange, indicating the air is unhealthy for some sensitive people. Ulrich says local areas that too often exceed the limits could lose federal transportation improvement funding. Ground-level ozone is created by nitrous oxides from car exhaust and power plants in the presence of heat and sunlight.
