    We tracked each site from the day of the notice to proceed (NTP) to the submittal of reports. Detailed stand-alone documentation -- highlighting State Historic Preservation Office (SHPO) exemptions -- was produced promptly and delivered to the client to meet its regulatory requirements. ATC teamed with a local cultural resources firm to obtain SHPO approvals as needed.  Additional services included geotechnical and foundation investigations, as well as wetland and wildlife permitting.

 

Environmental Due Diligence: Crude Oil Production Facilities

Situation:  A petroleum client was preparing to close facilities over a 300+ square-mile area that operated from the early 1960’s to 2005:  production wells, storage tanks, pumping stations and pipelines. The transaction was part of a process to return leases for crude production facilities to the landowner.

 

Results: ATC helped this petroleum client significantly reduce its liability and risk and achieve a documented cost savings of $480,000. The strategic approach included development and implementation of a Phase II Due Diligence effort. By leveraging refining and transportation business unit relationships, ATC helped the client reduce transportation costs and eliminate tipping fees for crude-impacted soils.  Regulatory closure was granted to 22 of the 23 identified sites.

 

Brownfield Assessment & Redevelopment

Situation:  A five-acre wooded municipal site was targeted for redevelopment.  The plan:  build a small sewage treatment plant to address the city’s sewage-overflow problem.  The facility would hold three          1.5-million gallon tanks in which high-flow sewage would be held and/or treated on-site.  This was a classic Brownfield.  It had remained vacant since its municipal well was closed 20 years ago, its groundwater affected by an adjacent property under remediation.  

 

Results:  ATC helped the client save approximately $260,000 in waste disposal costs by managing impacted materials on-site.  Our concurrent plan of environmental and geotechnical drilling saved an additional $10,000 and ensured consistent and representative data collection.  Further, we developed site-specific exposure models and associated human-health risk calculations to facilitate local on-site waste management.  Among the payoffs:  the development of engineering controls to mitigate exposure pathways.  We implemented excavation and off-site disposition methods to remediate areas of environmental impact, primarily from residual 55-gallon drums, pesticides and paint waste.  ATC continues to monitor construction and environmental impact and perform associated materials testing.
