Many pollutants such as oil and grease also bind to sediments, and are then transported into waterways along with the sediment. EPA investigators inspected the Redding site in 1998 and again in 1999 after two earlier violation notices from the Central Valley Regional Water Quality Control Board went unheeded. American voters support clean diesel trucks and clean diesel fuel, according to a new national survey conducted on behalf of the American Lung Association. To enable use of advanced pollution controls, EPA also would require that refiners remove nearly all the sulfur from diesel fuel. Nearly nine of ten voters favored requiring 18 wheelers and other big diesel vehicles to use the best available pollution control technology even if it costs them more money, the survey found.
Voters also believe cleaner diesel fuel can have a positive impact on the nation's air quality.
More than 75 percent of voters said cleaner diesel fuel will make a difference in cleaning up air pollution. Voters favored diesel fuel cleanup even when told it would increase costs to consumers. Kala, a two year old male Asian elephant, died on November 29 of endothelial inclusion body disease, a herpes virus specific to elephants. Derby and her partner Ed Stewart , along with other animal welfare experts, said that the stress of being separated too early from his mother compromised Kala's immune system, leading to his viral infection and death. Kala was less than two years old when he was taken from his mother and the trauma of it must have been devastating.
