The property, formerly operated by TR Metro Chemicals Inc. (TR Metro), consists of 2.5 acres located at the foot of Hudson Avenue, in the Borough of Ridgefield, Bergen County, New Jersey. The site is bordered on the west by Conrail Railroad and light industry; on the south by a parking lot and a shopping center; on the east by Route 1 (Broad Avenue); and on the north Hudson Street and industrial facilities. It is designated on the Ridgefield Zoning Map for light manufacturing. TR Metro was the tenant of Brenner Ridgefield, LLC and operator an organic chemical storage and distribution business at the Site between 1987 and 1995. A General Information Notification was filed on June 29. 1995 under N.J.A.C. 7:26B Industrial Site Recovery Act (ISRA). TR Metro ceased operations at the Site in September 1995. Since the ISRA filing, the site has undergone several investigations which have included a Preliminary Assessment (1995), A Remedial Action Work Plan (RAWP-1997), and subsequently, a Remedial Action Report (RAR-2000) were prepared and submitted to the NJDEP and described the site investigations and remedial actions which had been conducted to address the Areas of Concern (AOCs) identified in the 1995 Preliminary Assessment. The remedial actions included, the closure of 14 underground storage tanks and 23 aboveground storage tanks as well as the installation of a soil vapor extraction/air sparging system (SVE/AR) to address groundwater recovery and treatment. The RAR-2000 recommended natural attenuation for groundwater. Having outstanding environmental issues, and no response from the NJDEP on the RAR-2000, Brenner Ridgefield LLC, retained E2PM to complete the environmental work at the site and to address continuing groundwater contamination of BTEX and chlorinated VOCs. At this time the SVE/AR system had not functioned for several years and E2PM decommissioned the system. E2PM performed additional soil sampling and groundwater monitoring to evaluate the following:

• Evaluate if previously unidentified sources remained at the Site in the location of the former aboveground storage tanks.
• Evaluate potential for off-site sources of groundwater contamination.
• Evaluate the state of the groundwater treatment system and former storm water management systems at the site which include the perimeter trench and oil water separator system.
• Evaluate uninvestigated areas for potential remaining soil impacts.
• Evaluate fill material used at the Site.
• Evaluate the potential for vapor intrusion in the onsite structure.

E2PM remedial investigations continue to detect elevated levels of VOCs including benzene, xylene, chlorinated compounds, methylene chloride and chloroform that exceed the NJDEP Groundwater Quality Criteria. In addition, concentrations of methylene chloride, xylene, tetrachloroethene, vinyl chloride and chlorobenzene, arsenic and zinc that exceed the impact to groundwater (IGW) NJDEP soil cleanup criteria. The perimeter trench drain system was visibly inspected and housekeeping issues have been identified and continue to be addressed by E2PM. A Remedial Action Work Plan is being developed to address areas of soil impact which exceed NJDEP Soil Remediation Standards as well as continued groundwater investigation and monitoring activities.

E2PM services were provided to resolve the outstanding environmental issues identified at the Site; and since July 2010, E2PM has provided all environmental consultation and investigative services under the NJDEP LSRP program under the NJDEP Site Remediation Reform Act, N.J.S.A. 58:10C-1 et seq. (“SRRA”) and Executive Order #140, implementing the new law. This is an ongoing project and it is E2PM’s intent to bring this case to closure with the issuance of a Response Action Outcome (RAO) for soils, followed by a RAO for groundwater at a later date.
