Environmental Engineering & Consulting Projects

Phase I & II ESAs: Completed Phase I & II Environmental Site Assessments (ESA) following the current United States Environmental Protection Agency (USEPA) and the American Society of Testing and Materials (ASTM) guidelines for a historic clay mining and brick manufacturing plant property in Morgan County, Missouri.  Reviewed historical documents and public records; conducted interviews with past and current owners, the local historical society, and adjacent property owners; and performed a site characterization consisting of the collection of soil and groundwater samples.  Compared the analytical results to current Missouri Risk-based Corrective Action (MRBCA) guidance Risk-Based Target Levels (RBTLs) and prepared ESA reports. 

Brownfield/Voluntary Cleanup Program:  Development of a Remedial Action Plan and leaking underground storage tank (LUST) closure report for a petroleum contaminated site in Cole County, Missouri.  Field activities included the collection of environmental samples and removal of petroleum-contaminated soil and LUSTs in accordance with the Missouri Risk-based Corrective Action (MRBCA) Petroleum Storage Tank (PST) technical guidance document.  Project work was performed under the Missouri Brownfields Revolving Loan Fund administered by the Missouri Environmental Improvement and Energy Resources Authority (EIERA) with oversight by the MDNR Brownfields/Voluntary Cleanup Program (B/VCP).

SPCC Plan: Prepared a Spill Prevention, Control and Countermeasure (SPCC) Plan for a petroleum bulk storage facility in Franklin County, Missouri in accordance with the United States Environmental Protection Agency (USEPA) requirements of 40 CFR Part 112.  The SPCC Plan included the identification of potential sources of oil discharges and provided solutions to minimize the possibility of discharge occurrence.  Services included a site inspection, oil inventory, secondary containment evaluation, and the development of procedures and site plans.
