Bath Landfill : Decatur, Illinois.

"32571"--Colophon.

Bath, Inc. Landfill : Macon County, Illinois.

The 17-acre landfill southwest of Decatur on the south bank of the Sangamon River was permitted in 1974 as a demolition debris landfill. It originated as an open dump in 1918. The site had a history of not complying with the state landfill rules in the 1980s. The landfill also exceeded its permitted waste disposal limits, by the time that the operations stopped in 1991. The owner failed to comply with an August 1994 court order requiring proper cover to be installed and maintained. Visible leachate seeps (leachate is water that has traveled through the landfill and contacts waste material) and exposed refuse were observed along the bank of the Sangamon River. ... This landfill was one of the 33 landfills in Illinois identified by the Illinois EPA in 1998 as most in need of immediate repairs. The state legislature responded by passing legislation that allocated $50 million over five years to address these 33 sites. These 33 landfills are being managed through the Abandoned Landfill Program.
