A current or former quarry, mine, or other excavation site where CCDD or uncontaminated soil is used as fill.

CCDD includes any of the following materials generated from construction or demolition activities:
· Uncontaminated broken concrete free from protruding metal bars
· Bricks
· Rock
· Stone
· Reclaimed asphalt pavement
· When uncontaminated soil is mixed with any of these materials, the uncontaminated soil is also considered CCDD.

Uncontaminated soil is soil generated during construction, remodeling, repair or demolition of utilities, structures and roads that does not contain contaminants in concentrations above IEPA-established TACO Most Conservative Standards – You can learn more about the Maximum Allowable Concentrations of Chemical Constituents In Uncontaminated Soil Used as Fill Material on the IEPA website http://www.epa.illinois.gov/topics/waste-management/waste-disposal/ccdd/index

As the owner of any soil or CCDD taken to a fill operation, you must certify that it is either uncontaminated or that it meets the MAC Standard.

Depending on where the material is coming from influences what happens.  If not sure you should hire an Environmental Professional to determine if it is contaminated and provide a pH test and certification by the owner of such.
If the material is from residential and/or agricultural the form LPC-662 is used and if your consultant determines your material is coming from a industrial/commercial property after doing research then from LPC-663 is used.
