PM Environmental, Inc. was retained to complete a Phase I and Phase II Environmental Site Assessment (ESA) and cost to remediation documentation for the Warrior Asphalt Refining Property in Tuscaloosa, Alabama. The site has been a bulk petroleum storage facility and heavy distillate refinery for over 60 years.
The Phase I ESA identified Recognized Environmental Conditions (RECs) at the facility, which allowed the scope for a Phase II ESA to be completed. The primary RECs were associated with the petroleum storage and refining operations.
The Phase II ESA was conducted in two phases and consisted of a network of soil borings and a combination of temporary and permanent monitoring wells. A combination of chemical analysis was completed in soil and groundwater samples to delineate impacted areas. Soil impact was detected, and delineated during the investigations. Free phase hydrocarbons (fph) was detected in two areas, and was also delineated. Minimal dissolved groundwater impact was detected outside of the fph plumes.
PM completed cost estimates for remediation based on Alabama Department of Environmental Management (ADEM) regulations and the Voluntary Cleanup Program (VCP). These findings were presented by PM to representatives of the buying and selling entities and their legal counsel. Both sides accepted the findings and used the results in final negotiations for the purchase.
