Clean Construction or Demolition Debris (CCDD)

CCDD fill operators may measure the quantity of material received at their sites by either 1) weight, in tons, where the operator has weighed the CCDD or uncontaminated soil received with a device for which certification has been obtained under the Weights and Measures Act [225 ILCS 470], or 2) volume, in cubic yards, based on the known capacity of the hauling vehicle.

Yes. The fee applies to CCDD or uncontaminated soil if 1) the CCDD fill operation is located off the site where the CCDD or uncontaminated soil was generated, and 2) the CCDD fill operation is owned, controlled, and operated by a person other than the source site owner or operator of the CCDD or uncontaminated soil. It doesn't matter whether the source site owner or operator is a tax-exempt entity.

Chemical analyses must be conducted in accordance with "Test Methods for Evaluating Solid Waste, Physical/Chemical Methods" U.S. EPA Publication No. SW-846 as amended.

The appropriate sampling protocol will depend on the site and the suspected contaminants; this decision should be made by the licensed Professional Engineer or Professional Geologist who is responsible for certifying that the soil is uncontaminated.

The source site owner or operator or professional engineer should coordinate with the receiving facility in advance to make sure all soil received is properly certified. In many cases, one certification form per job site may be sufficient.

If using a source site certification form, the addresses where the soil originated should be listed. If using a professional engineer/professional geologist certification form, the address of the location of the stockpiled soil should be listed (e.g., a municipal public works yard). In both instances, the source site owner or operator or professional engineer/professional geologist should coordinate with the receiving facility.

LPC-662 must be signed by either the source site owner or operator. This form is used when the soil does not come from a "potentially impacted property." In cases where a load contains soil from multiple sites, the owner or operator of each source site must sign a LPC-662.

Part 1100 defines a "potentially impacted property" as "property on which a historical or current use, or contaminant migration from a proximate (nearby or adjoining) site, increases the presence or potential presence of contamination." The definition is "intended to identify soil that is more likely to be contaminated and in need of professional evaluation and certification" before it is placed in a fill site. Referenced in the definition are six different environmental site assessment standards or policies that may be used to help determine whether a property is potentially impacted.

If a property is determined to be "potentially impacted property", then any soil from that property must be evaluated, sampled and certified by either a professional engineer or a professional geologist using the LPC-663 form before it can be placed in a fill site.

If the professional engineer or professional geologist determines that the soil is not from a "potentially impacted property," then form LPC-662, the uncontaminated soil certification form for source site owners and operators, should be used. In this scenario, the source site owner or operator would sign the form and could attach supporting documentation prepared by the professional engineer or professional geologist affirming that the property is not potentially impacted and, consequently, does not require analytical testing for comparison to the MAC table.

Please note: all soil brought to fill operations for disposal, including soil mixed with CCDD, must have been pH-tested and must be certified on LPC-662 or LPC-663 forms, as applicable, to comply with the pH standard range of 6.25 to 9.0. In all cases, source site owners and operators are advised to coordinate with the receiving facility.

Yes. CCDD and uncontaminated soil fill operations are prohibited from accepting soil for disposal unless it is within the pH range of 6.25 to 9.0. All soil brought to fill operations for disposal, including soil mixed with CCDD, must have been pH-tested and must be certified on LPC-662 or LPC-663 forms, as applicable, to comply with the pH standard. The pH standard applies only to the soil component of CCDD or to uncontaminated soil. See QB8/AB8 and consult with the receiving facility for methods for soil pH testing.

The rule does not specify a method for soil pH testing. Therefore, any reproducible method generally regarded as accurate is acceptable. Bench-top methods are available from two organizations mentioned in the CCDD rule (Section 1100.104, Incorporations by Reference). Both the U.S.EPA and ASTM International provide procedures for determining pH in soil, SW-846 Method 9045D and Method D4972-01 2007, respectively. Also, numerous field kits and direct-read instruments are commercially available. These kits and instruments can provide reproducible and accurate results provided that the manufacturer's operating procedures are closely followed.

Soil pH is an important indicator for the nutritional maintenance of agricultural fields, golf courses, gardens, and commercial and personal lawns. Guidance is available from farm service organizations and landscapers regarding the number and acquisition of soil pH data to assure representative results. pH equipment manuals are also a good source for guidance. However, landscapers are generally only concerned with surface soil pH where source site owners must be concerned with varying depths of soil and fill operators are responsible for all soils that they receive.

The source site owner/operator, professional engineer, or professional geologist should coordinate with the receiving facility in advance to make sure the pH testing method selected is acceptable.

There is a single MAC Table provided by Illinois EPA. The same table applies to both CCDD fill operations and uncontaminated soil fill operations. In some cases an individual contaminant in the table may have more than one MAC. This occurs where the rules allow the background concentration of a contaminant to be used as the MAC in place of a more stringent value. MACs based on background are designated in the MAC table on the Agency’s website using footnotes (e) and (f).

Tables G and H of 35 Ill. Adm. Code 742.Appendix A contain multiple background concentrations for each contaminant. The applicable background concentration is based on the location of the CCDD fill operation or uncontaminated soil fill operation where soil is placed. Therefore, soil accepted at a fill operation can contain concentrations of a contaminant up to the background concentration that applies to the fill operation’s location. Because background concentrations differ based on location, Illinois EPA recommends coordination with the receiving facility to ensure that the proper background concentrations for that facility are being met.

Yes. However, only inorganic chemicals are eligible and not all of them qualify. Twenty-one inorganic chemicals presently qualify for this alternative compliance method. They are identified in the Agency MAC table by the footnote "m". While the Agency endorses all the TACO-based MAC criteria, the alternative, extraction-based results reflect the most trustworthy estimation of a soil's potential to contaminate groundwater.

Extraction-based TCLP/SPLP tests are not appropriate for determining compliance of Arsenic to its MAC. The primary exposure route of concern for Arsenic is the ingestion of contaminated soil. The drinking water route, which extraction testing exemplifies, is a secondary concern.

The Arsenic MAC was developed using the 35 IAC 1100.Subpart F methods. The first determination is described in 1100.605(a)(1) of the rule which directs the user to find the lowest TACO pathway-specific value for the Residential and Construction Worker receptors.

For Arsenic, the available choices for the ingestion pathway include 0.4 mg/kg and 61 mg/kg, residential and construction worker, respectively, and for the inhalation pathway, 750 mg/kg and 25,000 mg/kg, residential and construction worker, respectively. For the soil component of the groundwater ingestion pathway, section 1100.605(a)(3)(A) directs the user to the receptor-independent pH-specific value of 29 mg/kg. The lowest value of the above array is the residential soil ingestion objective of 0.4 mg/kg. Arsenic is unique in that the value of 0.4 mg/kg does not appear in the TACO rules where it has been replace by a footnote referencing Arsenic’s background concentrations. However, this value must be considered when using Subpart F of the CCDD rules.

The value of 0.4 mg/kg would be the final MAC except that section 1100.605(b) specifies that no MAC should be less than the TACO location-based background concentrations for that chemical. Thus, the MACs for Arsenic are its respective background values of 11.3 mg/kg for non-MSA counties and 13.0 mg/kg for MSA counties.

No. Analytical results cannot be averaged. Samples from potentially impacted property cannot be composited. Samples from a site that is not potentially impacted property can be composited if they are composited in accordance with 35 Ill. Adm. Code 1100.610(d). Samples for volatile chemicals can never be composited.

In order to be used as fill in a CCDD fill operation, painted CCDD must be certified by a professional engineer or a professional geologist utilizing the LPC-667 Form developed by the Agency. Except in the circumstances involving pavement markings discussed in answer AB13 below, sampling and analyzing the paint on the CCDD is an integral part of the certification process.

Yes, certification is always necessary for painted CCDD to be used as fill in a CCDD fill operation. However, if the CCDD is limited to broken concrete, asphalt pavement or other roadway CCDD and the paint on it is limited to pavement markings that comply with IDOT specifications for pavement markings, a professional engineer or professional geologist may attach the information used to determine that all these conditions have been met as provided for in Item d of Part 3 of the LPC-667 Form. In such cases, the paint does not need to be sampled and analyzed unless the professional engineer or professional geologist determines they are necessary to confirm compliance with IDOT specifications.

No. The Intergovernmental Agreement expired on August 27, 2012, the date the most recent amendments to the CCDD rules took effect.

An inspector designated by the facility must inspect every load before its acceptance at the facility utilizing an elevated structure, a designated ground level inspection area, or another acceptable method as specified in the Agency permit. In addition to a visual inspection, the inspector must use an instrument with a photo ionization detector utilizing a lamp of 10.6 eV or greater or an instrument with a flame ionization detector, or other monitoring devices approved by the Agency, to inspect each load. All instruments shall be interpreted based on the manufacturer's margin of error. Any reading in excess of background levels using any of these instruments must result in the rejection of the inspected load. In addition, any reading in excess of background levels on any monitoring device used by the Agency during an Agency inspection must result in the rejection of the inspected load.

No. CCDD facilities and uncontaminated soil fill operations are required by the regulations to reject any load that results in a PID reading above background level.

When a load is rejected the fill operation must provide the driver with a written notice containing certain information, including the reasons the load was rejected. The fill operation must also record information about the load and make the information available to the Agency. Rejected loads must be disposed of at a permitted landfill unless the requirements of 35 Ill. Adm. Code 1100.205(a)(5) are satisfied, in which case the load can be taken to a fill operation. Those requirements include correcting the reasons for rejection, and re-testing and re-certifying any soil.

Please note: The CCDD facility or soil only fill operation may reject any load at their own discretion. The responsibility falls to them to make sure only CCDD and uncontaminated soil are accepted for fill.

The CCDD rules apply to current or former mines, quarries, other excavations.

An "other excavation" is a "pit other than a quarry or mine created primarily for the purpose of extracting resources, including but not limited to, clay or other soil and does not includes holes, trenches, or similar earth removal created as part of normal construction, removal, or maintenance of a structure, utility, or transportation infrastructure."

For purposes of the CCDD rules, this definition applies only to soil that is generated from construction or demolition activities and used as fill material at CCDD facilities and uncontaminated soil fill operations.

In many cases the answer is yes. Sediments composed of naturally occurring materials are considered to be types of soil and dredging is considered to be a construction activity. Therefore, dredged sediments composed of naturally occurring materials, that have been properly certified to be uncontaminated soil, may be used as fill in CCDD fill operations and uncontaminated soil fill operations.

Yes, if the material is not removed as part of a cleanup or removal of contaminants (e.g., fill operators may accept clean overburden or other on-site soil or material that is not contaminated and is not being removed or treated as part of the remediation activities).

In such instances, the source site would be a potentially impacted property, requiring use of the LPC-663 uncontaminated soil certification form.

No. The CCDD rules only regulate the placement of soil in mines, quarries, and "other excavations". Outside of these areas uncontaminated soil may be used as set forth in Section 3.160(b) of the Environmental Protection Act. (415 ILCS 5/3.160(b)). No soil certification forms are required for uncontaminated soil placed outside of CCDD facilities and uncontaminated soil fill operations.

There is no numeric standard that provides an easy reference for when soil used outside of CCDD facilities and uncontaminated soil fill operations is considered uncontaminated. The MAC table applies ONLY to soil placed for disposal at CCDD facilities or uncontaminated soil fill operations.

No. The regulations do not provide a grandfathering clause for any projects or entities for any reason.
