Progress in Controlling Emissions:
Some progress has already been made in slowing the emission
of sulfur oxides. These decreases are the result of the 1975
Clean Air Act and and the 1990 Amendments.
In the Northeast there has been a steady decrease in the sulfate
content of the air and rain. The rate of acidifying lakes has
also slowed as well. To actually reverse the trend, the amount
of acid rain will have to be reduced much further. Some scientist
think that at least of 50 % reduction is required.
Solutions - Use Low Sulfur Coal:
The amount of sulfur oxides emitted by a power plant can be
reduced by burning coal with a very low percentage of sulfur
present. Low sulfur coal (0-1% sulfur) is surface mined in the
Western states of Wyoming and Montana. Transportation costs are
High sulfur coal (2-4% sulfur) is currently mined in the Midwestern
states of Illinois, Indiana, Ohio, West Virginia, and Kentucky.
If a complete switch to low sulfur coal is made, many coal miners
will lose jobs.
