Fill in the LPC-663 Uncontaminated Soil Certification

LPC-663 Uncontaminated Soil Certification: worksheet

I. Source Location Information

Describe the location of the source of the uncontaminated soil.

Soil gathered from several sites into one stockpile: on LPC-662 list each address the soil came from; on LPC-663 give the stockpile’s address.

County

Approximate center of the site, to five decimal places. No N.

The form prints the minus sign; enter the number without it, to five decimal places. No W.

Identify how the lat/long data were determined

The site’s 10-digit Bureau of Land number.

What is the LPC-663 form?

Illinois EPA’s certification that soil from potentially impacted property is uncontaminated soil, with a pH between 6.25 and 9.0, before it goes to a clean construction or demolition debris (CCDD) fill operation or an uncontaminated soil fill operation. A licensed professional engineer (PE) or licensed professional geologist (PG) evaluates the site, samples the soil, has it analysed and signs and seals the form.

The certification must be on Illinois EPA’s own form. Fill in this worksheet, then copy the answers into the LPC-663 PDF, print it, sign it, seal it and attach the evidence. The PDF only opens in Adobe Acrobat Reader; a phone or browser shows a “Please wait” page.

LPC 662 vs 663

LPC-662 is signed by the source site owner or operator, for soil from a site that is not potentially impacted property. LPC-663 is signed and sealed by a PE or PG, and is required for soil from potentially impacted property: a property where a past or current use, or contamination migrating from a nearby site, makes contamination more likely.

If the PE or PG concludes the site is not potentially impacted, the owner or operator signs LPC-662 instead and can attach the professional’s findings. Soil gathered from several places into one stockpile is certified on LPC-663 at the stockpile’s address.

What goes with LPC-663

Section III references the attachments: where the soil was sampled and why those points are enough, and the lab results showing every constituent within the maximum allowable concentrations set under Part 1100, Subpart F, and the pH within 6.25 to 9.0. The lab package includes the chain of custody, the lab report, the lab’s accreditation status and its certification that the analysis meets the accreditation rules.

Analysis follows U.S. EPA SW-846. The sampling plan is the PE’s or PG’s decision, based on the site and the contaminants suspected.

Questions

Does a certified load still get checked at the fill site?

Yes. Every load is inspected by eye and with a PID or FID meter before it is accepted, and any reading above background means rejection, whatever the certification says. Illinois EPA CCDD questions

Does each load need its own LPC-663?

Not usually. Illinois EPA says one certification per job site may be enough; agree it with the fill operation before the first load. Illinois EPA CCDD questions

What happens to a rejected load?

The driver gets a written notice with the reasons. The load goes to a permitted landfill, or back to a fill operation only once the reasons are fixed and the soil is re-tested and certified again. 35 Ill. Adm. Code 1100.205

Is the soil certification needed for painted concrete?

Painted CCDD has its own PE or PG certification, LPC-667. Illinois EPA CCDD forms
