Regulatory Agency: Pennsylvania Department of Environmental Protection (PADEP)
Contaminants: Petroleum Hydrocarbons
Remediation: Engineering Control and Limited Soil Excavation and Offsite Disposal
Scope: Lump Sum Remediation to Closure: Investigate, Investigate, Design/Build
- Careful evaluation of site characterization data highlighted the potential benefits of conducting a site-specific risk assessment.
- Specific risk assessment protocols and procedures were chosen that exceeded the ACT 2 requirements to add technical weight to the findings.
- Requirements for active remediation were eliminated and PADEP closed the case.
- ESI was able to share project efficiencies with the client resulting in a 50 percent rebate of the approved project cost.
Photo: ESI’s routine evaluation of risk assessment as a remediation pre-design tool was able to eliminate soil remediation at several facility locations where the Pennsylvania Department of Environmental Protection had open cases.
ESI was awarded a lump-sum contract of $1,400,000 to remediate petroleum hydrocarbons soil contamination at this specialty grease blending manufacturing and packaging facility.

Project work included performing a proper site characterization and installing engineering controls.
With effective site characterization, proper design and implementation of engineering controls, and knowledge of the ACT 2 process, ESI utilized the risk-based, site-specific remedial endpoints to reduce the client’s expenditures associated with the installation of a permanent remediation system, long-term system operation, and post- closure monitoring.
