What:  In 1997 the Environmental Protection Agency(EPA)
            
 established new ozone standards.  The EPA also placed special
            
 restrictions on twenty-two states in the Ohio Valley and Midwest
            
 regions to prevent emissions from coal-burning power plants from
            
 being carried into the New England States by wind currents. 
            
 (Tennessee is one of these twenty-two states.)  Both of these
            
 rulings were recently either struck down or placed on hold by
            
 	Why:  The regulations put into place in 1997 by the EPA were
            
 more restrictive than the 1990 standards.  The regulations limit
            
 the amount of ground level ozone and fine particle pollution
            
 permitted.  Ground level ozone is produced by nitrogen oxide(NOx)
            
 which is  created by burning fossil fuels.  Since gasoline and
            
 diesel are both fossil fuels, then NOx is a major component of
            
 automobile emissions.  Several members of the trucking and fossil
            
 fuel industries, as well as members of the twenty-two state
            
 region, have challenged the regulations in Federal Court and have
            
 been successful in blocking the implementation of the new rules. 
            
 In the past two months, two separate Federal Court Of Appeals
            
 panels have ruled that the EPA’s authority to establish clean air
            
 standards is not properly delegated by Congress under the Clean
            
 Air Act.  Therefore, since the EPA is a part of the Executive
            
 branch of government and not the Legislative, they have no
            
 authority to produce regulations on their own.  The plaintiffs in
            
 the case also argued that the amount of pollution a person can
            
 tolerate has not been established and until it is the EPA should
            
 not make the current regulations more restrictive.  
            
 	How:  The main actors in this event are the American
            
 Trucking Associations and their fellow plaintiffs, the twenty-two
            
 state coalition, the EPA, and the Federal Appeals Court.
            
 	Why would the American Trucking Associations and other
            
 fossil fuel burning industries want to...
