Design and construction of the site-wide remedy as described in the Record of Decision issued by the U.S. Environmental Protection Agency (USEPA) on September 27, 2012 is underway.
- Construction of the bedrock and overburden groundwater containment, extraction, treatment, and reinjection system, a major component of the site-wide remedy, is complete and the system is fully operational. The dedicated on-site groundwater treatment facility, located on Polhemus Lane in Bridgewater, will be operated long-term and groundwater will be monitored pursuant to requirements set forth by USEPA and New Jersey Department of Environmental Protection (NJDEP).
- Pre-design and design activities related to the site-wide soils remedy, including design of the stabilization/solidification treatment process for waste materials located in Impoundments 3, 4 and 5, will occur in 2022.
Impoundments 1 and 2
On September 25, 2018, the USEPA issued a Record of Decision (ROD) for Operable Unit 8 (OU8), commonly referred to as Impoundments 1 and 2. USEPA and Wyeth Holdings LLC (WH) executed an Administrative Order on Consent on September 30, 2019 that allows WH to move forward with design and engineering for the remedy as described in the ROD.
- In 2020, as part of the remedial design phase, a field demonstration of the remedy was performed. Information was collected to support the remedial design, such as the rate of material removal and preferred containers for shipping of the dewatered material to off-site treatment facilities. The demonstration work was safely completed and met air quality standards approved by both USEPA and NJDEP.
- In 2021, a larger scaled-up campaign was being performed to refine the remediation process and collect additional data for the final design. This work has been suspended as a result of flooding from Tropical Depression Ida. The project team will focus on flood recovery and final remedy design.
Impoundment 8 Facility
The Impoundment 8 Facility, located on Polhemus Lane, was designed to receive material exclusively from other areas of the Site as part of a multi-phase remediation program. The facility is regulated under the Resource Conservation and Recovery Act (RCRA) and work is addressed with oversight by the NJDEP, and the concurrence of the USEPA.
Less than 40% of the facility has been used to receive materials remediated during earlier remedial actions on the site, with the remaining capacity unused. Based upon USEPA’s selected remedies, the Impoundment 8 Facility will not receive any more material. Therefore, Wyeth is moving forward with plans to implement a final closure and post-closure care plan in accordance with RCRA regulations.
- WH is implementing a NJDEP-approved Remedial Action Work Plan which calls for a portion of the material within the Impoundment to be redistributed and regraded to lower the profile, improve aesthetics and allow for stormwater management. A final impermeable cover system will be put in place, along with a vegetative cover. Work is expected to continue through the end of the year.
- A community Air Monitoring Program (CAMP) is in place on-site, at perimeter fence line locations and near the intersection of Radel Avenue & Newberry Street to monitor the air for volatile organic compounds (VOC) and dust. Real-time monitors notify the team in the event that dust or VOC levels reach an advisory level – which is set well-below air quality criteria. In addition, manual equipment readings are used to further monitor for volatile organics, dust and odors.
- Redistribution and regrading of the material to lower the peak height of the impoundment is complete.
- Construction of the clean cap, which will consist of heavy-duty leak-proof liners, clean soil and grass vegetation to cover and permanently hold this material in place is currently underway. Construction of the cover system is anticipated to be completed by the end of November 2021. Vegetation will be planted in early spring 2022.
