Farmers fear dust rules won't reflect rural life  INDIANAPOLIS -
INDIANAPOLIS (AP) - As they begin the fall harvest, wary farmers
are watching a federal debate over whether to clamp down on one
of rural life's constant companions - the dust clouds that farm
machinery kick up in fields and along unpaved roads.  Farming
groups have urged the U.S. Environmental Protection Agency to
retain its current standards for dust, soot and other
microscopic particles, arguing that tighter restrictions would
be unworkable and that dust isn't a real pollutant.  Grain
farmer Charles Schmitt, who farms about 2,000 acres of corn and
soybeans near the southwestern Indiana town of Haubstadt, called
the possibility of tougher rules on dust "ridiculous."  The
59-year-old, who's farmed for more than four decades, said
there's little farmers can do to reduce dust, especially after a
dry summer like this year's that left his fields parched.
"Mother Nature has more to do with it than we do - there's going
to be dust and dirt no matter
