True North was retained by an architect on behalf of a school district to perform Leaking Underground Storage Tank (LUST) consulting services associated with a diesel fuel release at a former commercial and trucking logistics property they had acquired. A 10,000-gallon diesel fuel UST had been abandoned in place historically and was removed in July 2016 as part of the demolition phase of a larger improvement project.
The Illinois Office of the State Fire Marshal reported a release during removal of the tank, and the Illinois Emergency Management Agency and Illinois EPA LUST Program assigned the property a LUST incident number. Due to contaminated soils, the district elected to perform remedial activity (i.e., selective soils removal) in accordance with 35 IAC 734 to address impacts and prepare the site for future school grounds use. True North oversaw the remedial activities, including removal of impacted soils and collection of confirmatory soil samples in accordance with 35 IAC 734. The Illinois EPA also requested True North perform a groundwater investigation. Following completion of the remedial and assessment work required by the Illinois EPA, True North prepared technical reports for submittal to the Illinois EPA LUST Program, including a Combined 45-Day & Early Action Tier 1 Remediation Objectives Compliance Report and Site Investigation Completion Report meeting the requirements of 734. Ultimately, it met the regulatory requirements of the LUST program, and Illinois EPA issued a No Further Remediation Letter for the reported release. The site was subsequently improved as intended for use by the district.
