Illinois Administrative Code
Title 35 - ENVIRONMENTAL PROTECTION
Part 615 - EXISTING ACTIVITIES IN A SETBACK ZONE OR REGULATED RECHARGE AREA
Subpart G - ON-SITE WASTE PILES
Section 615.462 - Required Closure

A waste pile is considered to be a landfill and thereby subject to the closure requirements of Subpart D unless the operator can demonstrate to the Agency that the wastes are not accumulated over time for disposal. At the minimum, such demonstration must include photographs, records, or other observable or discernable information, maintained on a yearly basis, that show that within the preceding year the waste has been removed for utilization or disposed of elsewhere.
