RCRA Corrective Action - Streamlined and Sensible 

Taking full advantage of the RCRA Cleanup Reforms of 1999 and 2001 and working closely with EPA Region 2, NJDEP and our client, Princeton Geoscience greatly facilitated RCRA Facility Investigation (RFI) progress at an active solvent recycling facility in New Jersey. We used abbreviated, dynamic workplans and regular progress updates and data transmittals in lieu of formal reporting for each phase of work; fully utilized existing data for offsite areas and followed a site-wide rather than area by area investigative approach onsite. Major accomplishments to date: Documented Environmental Indicators prior to EPA’s target date; assessed/delineated extent of volatile organic compound (VOC) extent in soil and groundwater, including dense, non-aqueous phase liquid (DNAPL) in the soil and bedrock; conducted vapor intrusion (VI) sampling/assessment onsite and on four adjacent properties; developed a conceptual site model (CSM) that accounts for complex site conditions; prepared a three-dimensional groundwater flow model (MODFLOW); applied for and obtained an NJDEP Water Allocation Permit; obtained initial approvals from EPA and NJDEP for extraction and treatment system modifications to optimize a bedrock groundwater remedy that has operated since 1980. Current activities: Completing final delineation of offsite soil impact and DNAPL extent; negotiating final remedial system permit requirements; and establishing institutional controls, including Deed Notices and a groundwater Classification Exception Area (CEA). Planned activities: A Corrective Measures Study (CMS) will be conducted in streamlined fashion by applying NJDEP’s Remedial Action Selection guidance. The multi-phase RFI and CMS will be documented in a single RFI/CMS Report.
