Village of Lansing, IL
Former Police Station
Leaking Underground Storage Tank

​

Project Description

In 2011, a 10,000-gallon fiberglass unleaded gasoline/diesel fuel UST system that was installed at this former police station property in 1979, was removed from the site. Upon removal of the tank, a Leaking Underground Storage Tank (LUST) release incident was reported to the Illinois Emergency Management Agency (IEMA) and Robinson Engineering’s affiliate company,

GEOCON Professional Services, LLC completed the required Early Action, Site Investigation and Corrective Action activities and reporting to the Illinois Environmental Protection Agency (IEPA) for the LUST incident (20110966).

Key Project Elements

• Early Action activities included leaving contaminated media in the ground based on an assessment of risk, excavation sampling for BTEX, MTBE and PNA analytical testing and 20-Day Certification and 45-Day Reporting.

• Stage 1 and 2 Site Investigation activities included the completion of nine soil borings and seven shallow monitoring wells to define the extents of soil and groundwater contamination surrounding the former tank basin.

• Corrective Action activities included a Tier 2 Groundwater Evaluation, soil gas sampling for vapor intrusion pathways and the implementation of Institutional Controls which included: a full concrete slab-on grade or full concrete basement floor and walls for future potential buildings in the area of the remaining contamination, an on-site groundwater use restriction and an industrial/commercial land-use restriction. The IEPA issued a No Further Remediation Letter on February 20, 2015 to the Village for the LUST incident.

• GEOCON prepared reimbursement claims after each phase of work and the Village received 100% reimbursement of eligible costs from the Illinois UST Fund for the LUST incident less the $5,000.00 deductible established for the incident by the Office of the Illinois State Fire Marshal (OSFM).
