Coal Combustion Residual Surface Impoundments
Recent News
Navigation
35 Illinois Administrative Code Part 845 (Part 845) was created to satisfy a statutory mandate found in Public Act 101-171 which created Section 22.59 of the Act, directing the Illinois Pollution Control Board (IPCB) to adopt rules for a coal combustion residuals (CCR) surface impoundment permitting program.
Part 845 contains rules for the design, construction, operation, corrective action, closure and post-closure care of surface impoundments containing CCR at power plants. The rule includes groundwater protection standards applicable to each CCR surface impoundment at the waste boundary and requires each owner or operator to monitor groundwater.
CCR, or commonly referred to as coal ash, is formed when coal is burned at power plants. CCR consists of fly ash, bottom ash, boiler slag, flue gas or fluid bed boiler desulfurization by-products. CCR was commonly wet deposited, known as sluicing, into surface impoundments also called ponds.
The Illinois EPA recognizes seventy-two CCR surface impoundments at power generating facilities, based on best available information. Some of the surface impoundments are lined with impermeable materials, while others are not. Illinois EPA believes there are up to 6 CCR surface impoundments with protective liners. Unlined or non-protective liners may allow contaminants from the CCR to leach into the groundwater.
For more information on the reason and development of these rules, the reader is encouraged to read the Statement of Reasons for Part 845.
Who does this affect?
Part 845 applies to owners and operators of CCR surface impoundments, both on-site and off-site at electric utilities and independent power producers.
