How Long To Clean Air?
Don't expect it to let up soon. The USEPA announced that stricter clean air regulations will likely stay in effect for another 10-15 years.
The two major sources of pollution to clean up the air: nitrogen oxide and sulfur releases from power plants and diesel fuel and large truck engines.
If past experience is any indicator, we can look probably think in terms of another 30 years, possibly 45.
