Service Is Our Middle Name
CCDD stands for Clean Construction Demolition Debris which occurs when uncontaminated soil mixes with broken concrete without protruding metal bars, bricks, rock, stone, or reclaimed asphalt pavement. When this occurs, the soil is considered CCDD. For a more detailed description of what constitutes CCDD, please visit the Illinois EPA CCDD Site.
CCDD and its respective regulations are an Illinois specific program. Soil that falls under this classification can be disposed of at specific CCDD/USFO (Uncontaminated Soil Fill Operation) Sites as long as it is able to be proven that the soil meets the MAC (Maximum Allowable Concentrations) table requirements.
However, even if soil meets the MAC requirements, that doesn't guarantee that one of these facilities will accept disposal of your soil. Individual facility operators may have additional requirements or conditions. TSC has been an industry leader in getting excavated soil into CCDD/USFO facilities since the inception of the law over a decade ago.
The industry knowledge gained over this time has gotten excavated soil into nearly all of the CCDD/USFO facilities in the six-county Chicago suburban area, and, thereby, the awareness gained of their individual acceptance criteria, greatly improves your chances of disposal acceptance when you go with TSC.
In order to properly and legally dispose of your CCDD/USFO soil, there is a process that must be completed.
You will need a PIP (Potentially Impacted Property) Report. The first step of this process is the PIP investigation.
The PIP Report
In order to determine the condition of your site and sign off on the soil, we must conduct this investigation.
This includes a number of different action items: historical research, state and federal database searches, a site visit, and subsequent sampling and analysis.
Historical Research
Environmental professionals at TSC will comb through historical aerials, topographic maps, and other available historical
documents in order to see where at your jobsite are appropriate excavation locations to sample from for the purpose of determining
if there have been potential environmental impacts to the site, either from on or offsite.
Likewise, for what potential contaminants would be appropriate to sample for. If, for example, during this research, we learn the site was located next to a railroad, that would indicate that we should test for certain railroad related contaminants. Similarly, if the jobsite had, currently or previously, been a water treatment plant, that would lend itself to a separate, specific set of tests.
State and Federal Databases
Continuing on with the research phase, we'll look through State and Federal databases for your jobsite and
the surrounding properties, in order to see what public conditions are already known about it. This can save
you time and headaches by being able to identify things such as the historical presence of underground storage tanks.
All of this research will be included in the final report, so you are able to see the logic of why we are testing what we are testing.
Site Visit and Sampling
A site visit is then conducted as part of the investigation in order to get further clarification on things we found from
our earlier research or to spot other areas that may be of interest for sampling. The point of this is that we are thoroughly
looking through every possible avenue to get you accurate results. There is the research component, but this "boots on the ground"
approach is equally important to getting proper results.
If we are taking samples at the same time, then we may do that now too, or, we may complete staking of sampling locations for utility clearance/JULIE purposes for a return visit for sampling. Otherwise, TSC has the distinct advantage of having their own drill rig fleet for environmental and geotechnical samples.
Oftentimes, we will combine geotechnical engineering work with our environmental work as it can save both time and money for our clients as well as improving the accuracy of the samples taken since we are able to go much deeper then by traditional hand auger. Doing so can give us a sample that is much more representative of the conditions of the site soil to be excavated.
PID Screening and Lab Analysis
After samples have been collected, Environmental Professionals will use PID (Photo-Ionization Detector) screening to determine if volatile
chemicals are present in high enough concentrations to be a concern. This is a way that TSC differentiates itself from our competitors.
This preemptive check is very important as many of the CCDD/USFO facilities also use a PID device to screen soil as it is coming into their property. If soil fails this test at the entrance to their facility, then the soil will still be rejected regardless of a clean PIP report.
Once samples have been screened using the PID, we use a third party lab for soil sample analysis. Using a lab separate from ourselves further lends itself to our report's accuracy as they don't have a vested interest in the results. Usual turnaround time for the lab portion is about a week.
Reporting
Once we get the lab results, we are generally able to get a report out quickly to you that details the historical and database research from earlier,
the site visit, and finally the sampling results. Based on the testing results of the soil samples, we are able to tell you whether your site passed
or failed based on our research and comparison of sample results to the CCDD/USFO MACs.
If your site passes...
If your site passes then we will indicate that in the report and we will fill out the respective LPC-662/663 form.
For an LPC-663, a TSC Professional Geologist will sign and stamp the form for your CCDD/USFO soil, certifying it for disposal.
If your site qualified for LPC-662, the site's soil owner can sign that form themselves with the assurance gained from TSC's
thorough site property research.
You'll then be able to take your soil to the CCDD/USFO facility of you or your contractor's choice for disposal.
Keep in mind that the CCDD/USFO facility will require the full PIP report along with the LPC-662/663 form for acceptance.
Failure to produce the entire PIP report to the CCDD/USFO almost guarantees rejection of soil.
If your site fails...
If your site fails, TSC will outline the avenues that can be taken from that point, and we have extensive experience with getting your CCDD/USFO
rejected soil into a Subtitle D landfill facility. In accordance with this, TSC can also offer its experience with performing additional
sample locations around any failing soil sample in order to reduce the footprint of soil that will have to be excluded from disposal at a CCDD/USFO facility.
