PUBLIC NOTICE: DIAMOND ALKALI SUPERFUND SITE - LPRSA and NBSA SAMPLE DISPOSAL SET FOR AUGUST 15, 2024

PLEASE TAKE NOTICE THAT on August 15, 2024, the United States Environmental Protection Agency intends to proceed with the disposal of certain samples that were collected by EPA from 2005 to 2019 from the Lower Passaic River Study Area and Newark Bay Study Area, as part of EPA’s performance of response actions. The material to be disposed of consists of samples from sediment cores and traps, biota tissue samples, water samples and rinsate blank samples.

EPA analyzed most of the samples, using EPA-approved methodologies and has final validated data reported in accordance with the applicable Quality Assurance Project Plans (“QAPPs”).

EPA provides notice that it plans to dispose of certain Samples, as described herein, unless another entity takes custody of those Samples, in accordance with the terms of this notice.

Each of the Samples is beyond the holding time which is the period of time following the collection of the sample beyond which the sample will be unable to provide viable results. In addition, the volume of material remaining for certain Samples may be insufficient for laboratory analysis. EPA specifically reserves the right to argue in any forum that the Samples exceed their applicable holding time and are not viable for purposes of analysis, or that the results of any analyses performed on such Samples are flawed and/or unreliable and inadmissible as evidence.
The NBSA samples are 75 sediment split samples collected by EPA in oversight of the Occidental Chemical Corporation (“OCC”) Phases I (2005), II (2007) and III (2016) sediment coring for the remedial investigation. The oversight QAPPs governing the sampling are posted on ourNewarkBay.org or ourPassaic.org, in the Digital Library, "Sampling\Newark Bay" folder.
The LPRSA samples were collected by EPA in its performance of the lower 8.3-mile (“OU2”) remedial investigation/focused feasibility study (“RI/FFS”), and in its oversight of the 17-mile (“OU4”) remedial investigation performed by the Cooperating Parties Group (“CPG”), the River Mile 10.9 (“RM10.9”) removal action performed by the CPG, and the OU2 remedial design (“RD”) performed by OCC. The QAPPs governing the sampling are posted on ourPassaic.org, in the Digital Library, “Sampling\Passaic River” folder.
1. The OU2 RI/FFS samples are 644 sediment samples, two rinsate blanks and three water samples collected by EPA for the high resolution sediment coring (2005), low resolution sediment coring (2006), Dundee Lake (2007) and Empirical Mass Balance (2007-2008) programs.
2. The OU4 samples are 196 sediment split samples and 50 biota split samples collected by EPA in oversight of the CPG sediment and biota sampling from 2008 through 2013.
3. The RM10.9 samples are six sediment split samples collected by EPA in 2013 in oversight of the CPG’s performance of the RM10.9 removal.
4. The OU2 RD samples are 237 sediment split samples collected by EPA in oversight of the OCC pre-design investigation (2017 through 2019).
5. There are also two National Institute of Standards and Technology quality control sediment samples.
The Samples will be disposed of on August 15, 2024, unless the individual identified in Paragraph 7 receives written notice on or before August 8, 2024 that: (1) the interested party objects to EPA’s disposal of the Samples and provides a detailed and well-founded basis for such objection; and/or (2) the interested party is willing to take ownership and custody of the Samples and, if so, must execute an Ownership and Custody Agreement pursuant to Paragraph 5.
EPA has prepared an Ownership and Custody Agreement reflecting reasonable terms for transferring ownership and custody of the Samples to the interested party. The terms of the Ownership and Custody Agreement are non-negotiable. According to the terms of the Ownership and Custody Agreement, those interested parties who seek to obtain the Samples agree to accept responsibility for the transportation, care, storage, handling, maintenance, chain of custody, notice of later testing, and ultimate disposal of the Samples. The Ownership and Custody Agreement will also provide a date certain for the interested party to remove the Samples from the controlled storage units or otherwise take responsibility for payment of storage fees. A copy of the Ownership and Custody Agreement will be provided to an interested party upon EPA’s receipt of the notice described in Paragraph 4. The Ownership and Custody Agreement must be executed and returned within 30 days of EPA’s receipt of the notice described in Paragraph 4. EPA reserves its right to assert that any person or party that does not request an Ownership and Custody Agreement, or requests the Ownership and Custody Agreement but does not execute and return it within 30 days, has waived any claims or arguments regarding the transfer or disposal of the Samples by EPA.
In the event an interested party objects to EPA’s disposal of the Samples, the costs of storing these laboratory samples are considered response costs under CERCLA until (1) the party withdraws its objection or EPA concludes there is no valid basis for the objection or (2) EPA transfers ownership and custody to the interested party. If an interested party objects to disposal of a Sample but does not request to take custody thereof and EPA determines there is no valid basis for the objection, EPA will dispose of the Sample after making such determination.
If you are interested in obtaining ownership and custody of the Samples, please provide written notice in accordance with Paragraph 4 to Frances M. Zizila, 290 Broadway, 17th Floor, New York, NY 10007 and by email to zizila.frances@epa.gov. Notice must be received by August 8, 2024. In the event more than one private party demonstrates an interest in obtaining the Samples, the Samples will be provided on a first come, first serve basis.

Proposed Consent Decree with 85 Potentially Responsible Parties for Public Comment [December 2022]

EPA and the U.S. Department of Justice announce a proposed consent decree, a legal document, with 85 potentially responsible parties, requiring them to pay a total of $150 million to support the cleanup work and resolve their liability for discharging hazardous substances into the Lower Passaic River, which is part of the Diamond Alkali Superfund site. This consent decree is open for a 90-day public comment period and is available for review on the Justice Department website. Additional information is available on EPA’s Diamond Alkali Superfund Profile Page under “Site Documents & Data”.

EPA has updated the Community Involvement Plan (CIP) for the Upper 9 miles of the Lower Passaic River Study Area. The CIP was developed to encourage community involvement and to facilitate communication between EPA and community members, environmental groups, government officials, the media, and other parties interested in the site and cleanup actions at the site. This CIP provides the backbone of the community involvement program and serves as a useful resource that the cleanup team can turn to for advice on appropriate activities for community involvement. This CIP will serve as a roadmap for EPA in providing opportunities to share information with the public and to receive input during the interim and final cleanup action design and cleanup. It will be updated, as needed, to ensure opportunities for meaningful public participation continue throughout the interim cleanup action and beyond. This CIP is focused to fit the communication needs associated with the cleanup of the upper 9 miles of the LPRSA. It is structured to provide the reader with a high-level understanding of the work being done and to share EPA’s plans for keeping the community engaged and aware.

Record of Decision (ROD) for the Upper 9 Miles of the Lower Passaic River [September 2021]

EPA has finalized its decision on an interim cleanup plan for the sediment of the upper 9 miles of the Lower Passaic River that addresses sediment acting as a source of contamination for the Lower Passaic River Study Area, which is the lower 17 miles of the river.

The interim cleanup plan, called a Record of Decision, includes dredging approximately 387,000 cubic yards of contaminated sediment over approximately 96 acres from river mile 8.3 to the Dundee Dam. Contaminated sediment will be dredged to the depth(s) necessary to construct a sediment cap that does not diminish water depth or exacerbate flooding both under current conditions and considering climate change impacts.

After dredging, an engineered cap will be placed to prevent contamination in the sediment from entering the water column and fish tissue. Dredged sediment will be dewatered locally and transported off-site for disposal. Once the sediment is dredged and the cap placed, the water column, fish tissue, and sediment will be monitored to determine the final remedy for the river. The estimated cost of the remedy is $441 million.

The Record of Decision, including a Responsiveness Summary containing all of EPA’s responses to public comments on the cleanup proposal, is available here.

As part of a study of the Lower Passaic River being conducted by the Cooperating Parties Group, under EPA oversight, a detailed characterization of a mudflat adjacent to Riverside County Park in Lyndhurst found relatively high concentrations of dioxins/furans, PCBs, mercury and other contaminants. EPA collected samples of surface soil from Riverside Park at the end of January 2012 to look into whether dioxins, PCBs and mercury may have been carried into the park by periodic flooding. The results show that the measured concentrations of dioxins, PCBs and mercury present in soil are well below levels of concern. Based on its analysis, EPA does not plan on further sampling of the park's recreational areas and deems that cleanup actions on soil in the park are not warranted in this instance. The sampling report is posted on the Agency’s Diamond Alkali web site here (click on "Additional Documents").

Restoration Opportunities Identified for the Lower 8 Miles and Tributaries of the Lower Passaic River: Now Available for Review

Flooding of athletic fields along the Passaic River following Hurricane Irene and Tropical Storm Lee prompted the U.S. Environmental Protection Agency to collect samples of soil and sediment in late September at four locations in North Arlington and Lyndhurst, New Jersey. EPA proactively undertook an assessment to determine potential health impacts at these sites. Soil samples were collected from these recreational fields to screen for the presence of dioxins, furans and dioxin-like polychlorinated biphenyls (PCBs). Sampling was done out of an abundance of caution in connection with the on-going study of contaminated sediments in the Lower Passaic River. The results show that the measured concentrations of dioxins and PCBs in soil are below levels of concern. Fact sheet and the final report are available here (click on "Additional Documents").

Tierra Solutions, Inc. began mobilization and site preparation activities at the Diamond Alkali site for the Phase 1 Removal Action on July 12, 2011. EPA and the Army Corps of Engineers will oversee the work which will take place in 2011 and 2012 at two locations. About 40,000 cubic yards of contaminated sediment will be removed from within a sheet pile enclosure adjacent to the Diamond Alkali site, piped to an upland processing facility one quarter mile downstream on Blanchard Street, dewatered, and loaded in sealed containers for transport off-site for disposal. For a schedule, go to "Removal" under "Project Activities". Click here for a link to the Interim Final Community Health and Safety Plan.

Lower Passaic Environmental Dredging Pilot Successfully Completed

On December 5, 2005 New Jersey DOT, EPA and the U.S. Army Corps of Engineers launched a dredging and sediment decontamination pilot of a complexity never before conducted during an on-going feasibility study. Despite the brutal winter conditions on the river, the partner agencies achieved their dredging goal of removing close to 5,000 cubic yards of sediment. Three feet of sediments contaminated with PCBs, mercury, metals and dioxin, among others, were removed from the bottom of the Passaic River in a 1.5 acre area adjacent to downtown Newark. Some of the world's finest technical experts were brought to bear on this effort. It began a two-part evaluation of environmental dredging and sediment decontamination technologies that will include the collection of data on environmental dredging technology performance, productivity, re-suspension and treatability of contaminated sediments. The pilot project even made the cover of the December 2005 edition of WORLD DREDGING Mining and Construction. (Click here for cover)
