Brilliant! (not) I just can't understand how anyone would consider fouling air and or water that is common to all his or her neighbors. There is a cost to operating a diesel engine and the cost to the environment is part of it. Pollution controls on internal combustion engines place more of the cost of the pollution on the owner/operator, where they should be and less on the health and welfare of your neighbors. Can anyone seriously doubt the value of pollution controls on machinery or over the road vehicles after witnessing what the air quality was like in major U.S. cities, before and after. Just look at the situation China is in right now where you can hardly breathe due to pollution from coal plants and vehicles and machinery. The argument that, "Oh, I live in the country so I should be exempt", is false. Take responsibility for the mess you are making by shouldering the cost of cleaning it up at the source. Take a deep breath and have a nice day.
