This 17th annual report on municipal solid waste disposal and remaining landfill capacity is arranged by Illinois EPA administrative regions. Featured are specification pages describing the chief characteristics of 56 municipal solid waste landfills; their status (active, inactive, closed, under development); locations and hours of operation; tipping fees; quantities of wastes received in 2001, 2002 and 2003; remaining capacities on Jan. 1, 2003, and Jan. 1, 2004; solid waste management fees paid in 2003; names, addresses and phone numbers of landfill owners and operators. Quantities reported by landfills are given in gate cubic yards; as a convenience to the reader, those volumes are divided by 3.3 to provide rough equivalents in tons. The report also includes scaled-down specifications for 111 municipal solid waste transfer stations and 59 compost facilities. During 2003, 50 landfills reported receiving 57.0 million gate cubic yards of waste. This volume was almost 2.4 million gate cubic yards more than the total received during 2002, a 4.4 percent increase. As of Jan. 1, 2004, 49 landfills reported remaining capacities totaling 674.6 million gate cubic yards, or 26 million gate cubic yards less than on Jan. 1, 2003, a decline of 3.7 percent. Dividing wastes disposed during 2003 by capacity remaining on Jan. 1, 2004, suggests a landfill life expectancy in Illinois of 12 years, at current (2003) disposal rates, barring capacity adjustments, until capacity is depleted.
