By adhering to EPA’s “All Appropriate Inquiry” and ASTM E 1527-13 standards, LEL’s assessments are compliant with EPA’s Brownfields program.

Missouri has adopted the risk-based process which allows for more consistent decision-making from the Missouri Department of Natural Resources (MDNR). This process helps guide environmental remediation and monitoring with the end goal of “No Further Action” (NFA). Our consultants are well versed with the MRBCA Guidance document and with our environmental expertise can streamline any project from start to finish.


The Missouri Petroleum Storage Tank Insurance Fund (PSTIF) provides coverage to owners for underground and aboveground petroleum storage tank systems (UST and AST). Additionally, funds are available for the cleanup of tank site where USTs or ASTs were operated in the past if the property meets certain criteria. Leigh Environmental has years of experience working alongside PSTIF and we can help you apply for coverage, file claims, and check for coverage eligibility.
