Background: Historically, there have been three gasoline underground storage tanks (USTs) along with three fuel dispensers located at the Brothers Discount facility. The site was abandoned following Hurricane Katrina and is currently vacant and unoccupied. A line leak test conducted in March 1988 confirmed a release of regular unleaded gasoline while under operation of Berwick Bay Oil Company (BBOC). It was subsequently determined that an estimated 3,600 gallons of fuel was released. An automated, air compressor driven free product recovery system was installed onsite on December 30 ,1996 to aid in free product recovery. The Site has been sold and operated under various Facility names until being abandoned after Hurricane Katrina in 2005. On June 19, 2018, the Site was placed in the LDEQ Abandoned Tank Closure and Assessment Program. The USTs, dispensers, and associated product lines were removed by EDI Environmental Services, Inc. on May 20, 2020. The LDEQ issued a No Further Action (NFA) for the sampling results from the UST Closure on June 17, 2020.
Leaaf’s Role: Leaaf was contracted through Louisiana Department of Environmental Quality’s (LDEQ’s) Underground Storage Tank Division‘s Abandoned Sites Program to determine the current horizontal and vertical extent of contamination remaining in the soil and groundwater. Leaaf prepared a Site Investigation Work Plan and Cost Estimate for LDEQ. Following approval of the plan, Leaaf conducted Risk Evaluation/Corrective Action Program (RECAP) Management Option (MO)-1 site investigation at the site. Based on recommendation from Leaaf, LDEQ issued an NFA notification for the Brothers Discount site.
