While there remains much to
be done in controlling toxic air pollutants, Vermont has been proactive
in developing and implementing programs to reduce hazardous air pollutant
emissions. These programs include:
and Maintenance Program for Motor Vehicles
Motor vehicles are a major source of toxic air pollution. Equipment installed
by manufacturers to reduce this pollution is of little benefit when
not operating properly. This program requires checks for the
presence and/or function of important components of a vehicle's
emission control system as part of the annual Motor Vehicle Inspection
Program administered by the Department of Motor Vehicles. The program
requires a visual check of the vehicle's catalytic converter, a
check for the presence of a fuel tank cap, and a check of vehicle's
diagnostic system (OBD) on model year 1996 and newer vehicles.
Stage I & II Gasoline Vapor Recovery Program
new environmental regulations have led to the phase-in of gasoline
vapor controls at many filling stations in Vermont. These controls
are referred to as Stage I and Stage II Vapor Recovery Systems.
Stage I captures gasoline vapors displaced from a station's underground
storage tanks when fuel trucks make a delivery. Stage II captures
gasoline vapors displaced from motorists' fuel tanks during refueling.
Both systems create a closed loop which keeps gasoline vapors from
escaping into the air. Gasoline vapors contain more than 200 chemicals,
many of which are toxic or carcinogenic (cause cancer), such as
benzene. Stage I and II Vapor Recovery systems will help reduce
our exposure to these toxic chemicals.
Low Emission Vehicle Program
2000 model year, vehicles sold in Vermont will have to meet the
state of California emission standards. This will result in cars
that are 50 to 70% less polluting than the conventional vehicle.
The program will require zero emission vehicles to be sold in
Vermont, once the technology is demonstrated to meet certain performance
