Underground Storage Tanks
According to the United States Environmental Protection Agency (US EPA), approximately 585,000 underground storage tanks (USTs) store petroleum or hazardous substances nationwide. Leaking underground storage tanks contaminante subsurface soils and pose a threat to groundwater quality. In Illinois, the Office of the State Fire Marshal (OSFM) and the Illinois Environmental Protection Agency (IEPA) are the regulatory agencies responsible for the management of UST related issues to ensure the protection of public health and safety.Hygieneering offers technical expertise associated with UST requirements and regulations and has successfully managed the closure of USTs through the OSFM removal or abandonment-in-place process. Hygieneering also offers environmental consulting services pertaining to leaking USTs and has successfully managed remediation of leaking UST sites under the IEPA’s Leaking Underground Storage Tank (LUST) Program. The LUST Program oversees remedial activities associated with a petroleum release from a UST system. Once the site has met its remediation objectives and requirements, the IEPA issues a No Further Remediation Letter (NFR) for the leaking UST incident. The NFR letter is signifies that remedial objectives and regulatory requirements have been satisfied.
