Risk Assessment Workshop for the Newark Bay Study Area [June 2011]:
On June 28 and 29 2011, a Human Health and Ecological Baseline Risk Assessment Workshop for the Newark Bay Study Area was conducted.
The participants included representatives from the EPA, NOAA, USACE, USFWS and Tierra Solutions.

Final Phase I and Phase II Sediment Deposition Report [October 2011]:
The Phase I and Phase II Sediment Deposition Report assesses the radiochemical data
collected as part of the Newark Bay Study Area (NBSA) Phase I and Phase II Sediment
Investigation Programs. The report provides a summary of methods used for sediment dating,
estimates deposition rates, and estimates the 1940 horizon depth.

Final Screening-Level Ecological Risk
Assessment [December 2008]: In order to
identify the potential for contaminants within the
Newark Bay Study Area to adversely affect ecological
receptor populations and to determine whether additional
ecological evaluation is necessary, a screening-level
ecological risk assessment (SLERA) was performed. This
SLERA includes a conceptual site model, the contaminants
of potential ecological concern, and a preliminary
exposure assessment performed using conservative

completed during Phase I and Phase II of the Remedial
Draft Natural Resource Damage Assessment Plan
NOAA and USFWS announce the availability of a draft
Natural Resource Damage Assessment Plan for public
comment. The Natural Resource Damage Assessment Plan is
one step in the damage assessment process. It serves to
document exposure of natural resources to hazardous
substances and identify anticipated procedures for
evaluating natural resource injuries potentially caused
by such exposure.

Phase 2 Remedial Investigation Work Plan
Approved [October 2007]:
EPA has approved the Newark Bay Phase 2 Remedial
Investigation Work Plan (RIWP) which was developed by
Tierra Solutions, Inc. (TSI) in accordance with the
requirements of an EPA Administrative Order on Consent
dated February 2004. The RIWP briefly summarizes the
Phase 1 sediment sampling program (a detailed evaluation
of the Phase 1 and 2 results will be performed upon
receipt of the validated Phase 2 data), it describes the
Phase 2 project quality objectives for the field work,
and it outlines the tasks to be performed during the
Phase 2 sediment investigation program. The primary
purpose of Phase 2 is to characterize sediments in
select areas of Newark Bay that have had significant
accumulation of sediments since 1940. The
characterization of sediments during Phase 2 will
enhance EPA's understanding of contaminant deposition
and distribution patterns over time in Newark Bay and it
will help identify upland sources of contaminants.
Collection and analysis of sediment cores began on
October 23, 2007 within varied geomorphic units in
Newark Bay (e.g., navigation channels, sub-tidal flats).
Fifty-two sediment cores will be collected and analyzed
for select contaminants. Phase 2 work is generally
considered to be an extension of Phase 1 work. A Phase 3
effort will be needed in the future to fully accomplish
all of the remedial investigation goals.
The Phase 2 RIWP includes an Investigation Work Plan,
Sampling and Analysis Plan, Site Management Plan, and
Quality Assurance Project Plan (Volumes 1 & 1a), and a
Health and Safety/Contingency Plan (Volume 2).

Second Municipality Workshop Held
A second workshop for municipalities was held on July
12, 2007 in Newark, bringing together municipalities in
the lower 8 miles of the Passaic River and in the Newark
Bay area with federal-state partner agencies to discuss
possibilities for integrating municipality plans and
visions with federal-state cleanup and restoration
projects. This workshop was a follow-up to the April 18,
2007 municipality workshop.

Workshop Held to Discuss Integration of
Municipality Plans & Visions with Federal-State Cleanup
& Restoration Projects
A municipalities workshop was held on April 18, 2007
in Newark, bringing together municipalities throughout
the lower Passaic River and Newark Bay with
federal-state partner agencies and key stakeholder
groups to discuss possibilities for integrating
municipality plans and visions with federal-state
cleanup and restoration projects.
The partner agencies provided the more than 75 in
attendance with an opportunity to initiate or continue a
dialogue between waterfront municipalities and
federal-state agencies. Discussions also took place on
how to continue the coordination of municipal
redevelopment activities with agency cleanup and
restoration work. You can find out more about the
meeting by reading the
COMMUNITY INVOLVEMENT PLAN FINALIZED
The partner agencies have prepared and completed the
Community Involvement Plan (CIP) for the Lower Passaic
River Restoration Project and Newark Bay Study. The
commitment of the partner agencies to active and open
public involvement forms the basis of this document. The
CIP provides a toolbox of options for keeping the public
informed and for soliciting input. As a living document
for a dynamic project, the CIP will be reviewed
annually, and updated as needed to reflect project
progress and changes to community needs, concerns,
issues, and contacts.

EPA Demonstrates Bold, New Technology That Turns
Contaminated Sediment into Useable Soil
On March 24, 2006, EPA hosted an event in Woodbridge,
New Jersey demonstrating an exciting new technology that
takes contaminated sediment and turns it into high
quality top soil. This soil washing process is patented
by BioGenesis Enterprises, Inc., and is being used to
treat approximately 4500 cubic yards of sediment from
the Passaic River.
