New York State is legally obligated to regulate fuels under US EPA guidelines. DEC's principal mobile source fuel programs are:
- Control of gasoline volatility
- Oxygenated gasoline
- Reformulated gasoline
- Low-sulfur diesel fuel
- Gasoline vapor recovery
DEC is also actively working on future fuel programs to reduce ozone and to abate diesel particulate and nitrogen oxide emissions, and to assess and limit adverse health effects from exposure to fuels and associated combustion products in both air and water.
Fuel programs usually have a short initiation period and immediately cause emission reductions in all vehicles. In most cases, these emission reduction benefits from cleaner fuels extend to engines in non-mobile applications (lawn and garden, boats, stationary engines). The consumer may also benefit from greater engine durability and save money by using less fuel.
