  discharges. Storm water discharge regulations under this Act require a permit for certain construction 
  activities and discharges from industrial operations and facilities, which may aÅect our operations. If a 
  landÑll or transfer station discharges wastewater through a sewage system to a publicly-owned treatment 
  works, the facility must comply with discharge limits imposed by that treatment works. In addition, states 
  may adopt groundwater protection programs under this Act or the Safe Drinking Water Act that could 
  aÅect solid waste landÑlls. Furthermore, development which alters or aÅects wetlands must generally be 
  permitted prior to such development commencing, and certain mitigation requirements may be required 
  by the permitting agencies. 
  
  (4)*The Clean Air Act, as amended.*The Clean Air Act imposes limitations on emissions from 
  various sources, including landÑlls. In March 1996, the U.S. EPA promulgated regulations that require 
  large municipal solid waste landÑlls to install landÑll gas monitoring systems. These regulations apply to 
  landÑlls that commenced construction, reconstruction or modiÑcation on or after May 30, 1991, and, 
  principally, to landÑlls that can accommodate 2.5 million cubic meters or more of municipal solid waste. 
  The regulations apply whether the landÑll is active or closed. The date by which each aÅected landÑll is 
  required to have a gas collection and control system installed and made operational varies depending upon 
  calculated emission rates at the landÑll. Many state regulatory agencies also currently require monitoring 
  systems for the collection and control of certain landÑll gas. We do not expect that compliance with any 
  new state regulations will have a material eÅect on us.
