RPS was retained to facilitate the purchase and redevelopment of a 2.2-acre property along the Atlanta Beltline, a comprehensive redevelopment program along former railroad corridors, in downtown Atlanta. Former site occupants included an oil distribution company, a gas station, and several automobile service facilities.
Highlights
- Former oil distribution, gas station, and auto repair site
- Soil and Groundwater Investigation
- Soil and Groundwater Sampling
- Site Enrollment into Brownfield Program
- Prospective Purchaser Corrective Action Plan
- Cleanup up to Unrestricted Use Criteria
Challenge
RPS conducted a preliminary site investigation by installing and sampling four soil borings and nine temporary groundwater points to characterize site conditions and identify any potential subsurface impacts. Results indicated residual subsurface impacts and RPS worked with the purchaser to enroll the site in the Brownfield Program and development of a Prospective Purchaser Corrective Action Plan (CAP). The Georgia Environment Protection Division (EPD) required additional investigation to further characterize site conditions, which included installation and sampling of 29 soil borings and three permanent groundwater wells. The additional characterization data was utilized to develop a corrective action strategy for removing impacted media from the site to meet unrestricted use criteria.
Solution
Corrective measures were implemented at the site. A former above ground storage tank area was excavated to remove petroleum impacted soils. During the excavation activities, tow legacy underground storage tanks (USTs) were discovered. The USTs were registered with the Georgia Underground Storage Tank Management Program and closed under the Brownfields CAP. Approximately 1,749 tons of soil were excavated and transported for off-Site disposal at the Republic Services Pine Ridge Landfill. Post-excavation confirmatory testing indicated impacts had been removed to residential criteria.
A Compliance Status Report detailing the investigation and remedial activities was prepared and submitted to the EPD certifying compliance with residential unrestricted use criteria. The Georgia EPD issued a “limitation of liability” for the site on October 13, 2020.
