Executive Summary
For over two decades, the Niagara River has been the focus of attention between four environmental
agencies in the United States and Canada (Athe Four PartiesiS). On February 4, 1987, the Four Parties
signed a Declaration of Intent (DOI) to achieve significant reductions of toxic chemical pollutants in the
Niagara River. The DOI outlined the principles and activities to be followed and was combined with a
detailed annual work plan which forms the Niagara River Toxics Management Plan (NRTMP). The Four
Parties agreed upon a specific list of 18 'priority toxics" targeted for reduction through the NRTMP. A
key sub-objective and milestone of the NRTMP DOI was to achieve a 50% reduction of ten specific
priority toxics believed to be from significant Niagara River sources by 1996.
In a 1988 study report, 33 hazardous waste site clusters were identified and prioritized in order of
potential for toxic pollutant loadings to the Niagara River. The 33 cluster sites were placed into three
categories: Category I (sites with loadings greater than 50 lbs/day), Category II (sites with loadings
between 1 and 50 lbs/day), and Category III (sites with loadings less than 1 lb/day). The EPA and
NYSDEC consolidated the list of 33 cluster sites into a priority list of 26 sites consisting mostly of
Category I and II, which were determined to be responsible for -700 lbs/day of the 18 priority toxic
chemical loadings to the Niagara River, and, represented the most significant input of non-point source
loadings (99.9%) from the U.S. side of the basin. The complete remediation of these sites became the
primary focus of the NRTMP to achieve the common goals of the Four Parties agreement. In December
1996, the Four Parties formally re-affirmed, by Letter of Support, their commitment to continue
reductions of priority toxic loadings to the Niagara River. Overall, the NRTMP has met its 50% reduction
goal for the ten targeted priority toxics, and some by more than 75% through actions addressing point and
non-point sources of toxic contamination. Key actions addressing non-point sources include completing
21 of the total 26 priority hazardous waste sites to date. Water quality monitoring data for the period
April 2004 through March 2005 shows annual average concentrations for 6 of the 18 priority toxics
(Arsenic, Lead, total chlordane, pp-DDD, octachlorostyrene (OCS), and benzo(a)anthracene (a PAH) are
now substantially below the most stringent agency water quality criteria at Fort Erie (FE) and Niagara-on-
the-Lake (NOTL).
Today, the commitment to reduce toxic loadings through the NRTMP continues. The Four Parties are in
the process of evaluating past achievements and future opportunities that exist to coordinate with other
related program initiatives occurring within the basin utilizing available expertise and resources. Further
evaluation is needed on the opportunities that exist to continue to reduce toxic contaminant levels from
U.S. sources within the Niagara River. To meet this challenge, the Niagara River Secretariat is currently
evaluating input received over the past year from the general public and involved public and private
stakeholders on the future of the NRTMP. The Secretariat plans to integrate the input received into an
Options White Paper with recommendations to be presented to the Four Parties Coordinating Committee.
Based on feedback and direction on course of action received from the Coordinating Committee, the
Secretariat will revise the NRTMP Scope and Workplan based on consensus reached among the
Coordinating Committee members.

Introduction
Since 1987, the Niagara River has
been the focus of attention for four
environmental agencies in the U.S.
and Canada, called AThe Four
Parties®1. The Four Parties signed a
Niagara River Declaration of Intent,
pledging cooperation to achieve significant reductions of toxic chemical pollutants in the
Niagara River (DOI 1987). The Declaration of Intent and a work plan form the Niagara River
Toxics Management Plan (NRTMP).

Under the NRTMP, the Four Parties identified
18 persistent toxic chemicals as Apriority
toxics! Actions to reduce the inputs of these
priority toxics to the Niagara River have been
aimed at point sources and non-point sources.
Significant point sources on both sides of the
Niagara River have been identified and are
being addressed in U.S. and Canadian point
source plans. The Four Parties summarize
progress in controlling point sources in an
annual report, last issued in October 2007
(The Niagara River Secretariat, 2007). The
next progress report with 20-year trend
analysis is expected to be completed in
2009/10.
Non-point sources of toxic chemicals to the Niagara River (e.g., leachate from hazardous waste
sites, storm water runoff, atmospheric deposition) are more difficult to quantify and control.
Given the limited information available about non-point sources, the U.S. has proceeded with its
actions based on the assumption that hazardous waste sites are the most significant non-point
sources of toxic chemicals to the Niagara River.
In 1988, an EPA study estimated potential toxic pollutant loadings to the Niagara River from all
known hazardous waste sites on the U.S. side of the Niagara River (Gradient Corp/Geotrans Inc
1988). The study compiled a list of 70 sites into 33 "cluster sites" largely based on the manner
in which data has historically been collected. The study further placed them into three categories
based on their potential loadings (in lbs/day) to the Niagara River. Figure 1 shows the locations
of these 33 site clusters, as well as several other additional hazardous waste sites.

The study showed that a total estimated 694 lbs/day (315 kg/day) of toxic chemicals have the
potential of migrating from these 33 cluster sites to the Niagara River. Because collection of
site-specific transport data is ongoing, estimates were made based on certain assumptions, e.g.,
that groundwater flow is horizontal, and that pollutants behave in a conservative manner. These
assumptions yielded conservative estimates (i.e., estimates of toxic loadings that are expected to
be higher than the actual loadings).
Table 1 presents the 33 cluster sites divided into the three categories, based on
Gradient/Geotrans 1988 estimates of their potential toxic loads to the Niagara River. The
categories are as follows:
Category I: Sites with loading greater than 50 lb/day
Category II: Sites with loadings from 1 to 50 lb/day
Category III: Sites with loadings less than 1 lb/day
Sites from Category I and II collectively represented 99.9% of the total estimated loadings.
In November 1989, EPA and NYSDEC issued a report which prioritized the 33 cluster sites into
a list of 26 hazardous waste sites, consisting mostly of Category I and II, which were determined
to be responsible for the -700 lbs/day of the 18 priority toxic chemical loadings to the Niagara
River (EPA/NYSDEC 1989). Since 1989, EPA and NYSDEC have reevaluated the universe of
hazardous waste sites to identify those that new information shows are significant sources of
toxic chemicals to the Niagara River. Two sites have been removed as insignificant sources of
toxics, and four sites have been added as significant sources. This update reports on remediation
progress at the resulting 26 priority hazardous waste sites.
EPA estimates actual input loading reductions from completed hazardous waste site remedial
actions ("RAs") have been from -700 lbs/day to less than 50 lbs/day; representing an
approximate 94% reduction from the 1988 baselines for PCBs, DDT, mirex, octachlorostyrene,
chlordane, hexachlorobenzene, benz (a) anthracene, lead and others to the Niagara River. This
estimate is based primarily on assuming 100% reduction at sites where the final RA is
completed. It does not include the load reductions at other sites where interim remedial controls
are in place, e.g., groundwater pump-and-treat systems are functioning at 3 of the 4 sites where
remediation is underway and are expected to have already reduced off-site loadings. Since
estimates could not be made for these sites with on-going remediation, actual reductions to date
may be greater than the estimated 94%. Table 2 identifies the sites where final RAs are
complete and the sites where remediation is not yet completed, but which have interim
operational remedial systems that are expected to have reduced contaminant loads to the Niagara
River.
4
-------
Final RAs currently underway are expected to be completed at one additional site by the end of
2010 and another site by the end of 2011. Upon completion of these 2 additional RAs, EPA:s
best estimates are that the estimated toxic chemical inputs from all sites collectively should be
reduced by almost 98% from the 1989 inputs (EPA/NYSDEC 1989).
Other estimates have been made of the potential loadings of the NRTMP priority chemical
concentrations in groundwater and groundwater flow to the Niagara River from priority waste
sites. These estimates are based on information that was not available when the
Gradient/Geotrans estimates were developed. For example, a report by several site PRPs
addressing groundwater loadings for ten of the NRTMP priority waste sites estimated priority
chemical loadings from ten sites at 5.6 lbs/day (2.5 kg/day) prior to RA, and 0.0048 lbs/day
(0.002 kg/day) after RA completion, a reduction of over 99% (CRA 1998). Since these
estimates only consider the NRTMP priority chemicals, they are not comparable to the
Gradient/Geotrans estimates of total toxic chemical loading. In addition, the report also used
some assumptions (i.e. non-conservative assumptions) that would tend to reduce load estimates.
Therefore, although actual loadings are likely greater than the estimates, the estimates do
corroborate the reduction in toxic chemical loadings to the Niagara River achieved through
remedial programs.
In addition to remediation efforts at the waste sites themselves, it is also important to recognize
the role of the Niagara Falls Waste Water Treatment Plant (WWTP) in reducing toxic inputs
from a number of waste sites to the Niagara River. Based on information available in 1987, the
U.S. identified the Falls Street Tunnel, a major unlined industrial sewer cut into the bedrock
under the City of Niagara Falls, as the largest source of toxic pollutants from any of its point
sources. By the mid-1980s, the Tunnel was only receiving overflows of wastewater from the
sewers of a Niagara Falls industrial area, in addition to contaminated groundwater infiltrating
from major waste sites via cracks in the Tunnels bedrock walls. In contrast to flows from other
point sources, effluent from the Falls Street Tunnel entered the Niagara River untreated. In
1993, EPA and NYSDEC required the City of Niagara Falls to treat the Falls Street Tunnel
discharges during dry weather at the Niagara Falls WWTP. Data gathered by the U.S. indicate
that WWTP treatment of the Tunnels dry weather discharge has reduced mercury loadings by
70%) relative to 1980 loads, tetrachloroethylene loadings by 85%, and the loadings of four other
priority toxic chemicals by almost 100%.
Since the Falls Street Tunnel captures portions of the upper Lockport bedrock groundwater flow
from seven hazardous waste sites, the actions taken to control discharge from the Tunnel reduce
loadings from the following sites:
DuPont, Buffalo Avenue Solvent Chemical
OCC, Buffalo Avenue CECOS International
Frontier Chemical, Royal Avenue DuPont Necco Park
Durez Division, Packard Road Facility (formally OCC)
For this report, estimates of site loading reductions do not include those obtained through
treatment of the Falls Street Tunnel dry weather flow.

Status of Remediation Progress
Overview
As of the release of this 2009 NRTMP report, final RAs have been completed at 21 of the 26 sites
which includes all ACategory 1" sites (those with estimated contaminant loads of >50 lbs/day of
priority toxic chemicals to the river). It is expected that the post-remedial Operation, Maintenance
and Monitoring (OM&M) technology installed at certain sites could be operated, maintained and
monitored for continued effectiveness for up to 30 years or longer at other sites.
The remaining five sites (Mobil Oil, Frontier Chemical - Royal Ave., Vanadium Corporation,
Bethlehem Steel Corporation, and Buffalo Color Corporation Plant Site) have RAs pending or
underway. Three of the five sites (Mobil Oil, Vanadium Corporation, and Bethlehem Steel
Corporation) are operating interim remedial systems while progressing with completion of their final
RAs. Estimated RA completion date for Vanadium Corporation is December 2010 and for Mobil Oil,
December 2011. NYSDEC is currently negotiating a Corrective Measures Study (CMS) Consent
Order with Tecumseh Redevelopment (current owner of the Bethlehem Steel Corporation site) to
complete the remaining projects needed at the site with construction schedules. The other two sites
(Frontier Chemical - Royal Ave. and Buffalo Color Corporation Plant Site) have completed their
respective Remedial Investigation/Feasibility Studies (RI/FS) for their sites. The remedial
investigation of the Frontier Chemical - Royal Ave. site, operable unit (OU) No. 2 (deep bedrock
groundwater), is on-going and is expected to be completed in 2010. In 2009, the Buffalo Color
Corporation Plant Site was accepted into the NYS Brownfield Clean-up Program. A Remedial Work
Plan was approved in May 2009 and design activities will continue into 2010 as plant structures are
being demolished.

The sites in interim remediation are also under investigation or design, and therefore are listed twice.
Bolded sites have updated project highlights reported below in more detail.
These sites, though not completed, have operational remedial systems that are expected to
have reduced contaminant loadings to the Niagara River.
1 Preliminary investigations were completed. Two Interim Remedial Measure (IRMs) have been completed by PRPs for
OU#l and OU#2. A "No Further Action" Record of Decision was issued for OUs #1 and #2 in March 2006.
2 The RI/FS for soils and the upper bedrock (OU1) were completed in 2004 with a ROD issued in March 2006. An RI/FS
is still required for the deeper bedrock groundwater (OU2).
3 In 2004 DEC approved an interim corrective measures plan for the remediation of the Benzol Plant Area (i.e., the Coke
Oven Area). Recovery-well installation was completed in December 2004. The system includes LNAPL recover and
groundwater collection and treatment. The system began operating in April 2005.
Project Highlights
For each individual waste site, status summary tables are provided in Appendix A. Also, detailed site
information for all 26 sites can be found in NYSDEC's Environmental Site Remediation Database
website located at... http://www.dec.nv.gov/cfmx/extapps/derexternal/index.cfm?pageid=3. Updated
highlights of completed hazardous waste sites with continuing work and progress made at the five
remaining sites with RAs underway, particularly since the October 2008 NRTMP progress report, are
summarized below.
8
-------
Occidental Chemical - Durez
• Initial remediation of the site was completed in 1995. Based on post remedial monitoring
additional contaminated sediment from the bottom of the Pettit Creek cove area was removed
in May 2000. The most recent report from caged mussel bio-monitoring (-2006), indicates
elevated concentrations of dioxins and furans remain in sediment. A work plan for source
investigation and additional sediment removal, as needed, has been submitted by the
Company and approved by NYSDEC. The purpose of the work is to determine the source of
the recontamination and evaluate remedial alternatives. This work began in mid 2008 and a
progress report was submitted in 2009. NYSDEC has requested additional follow-up work
based on the results of the progress report.
Dupont Plant Site. Buffalo Avenue
• The lower reach of Gill Creek (OU#2), which was heavily contaminated with DuPont and
Olin plant site chemicals, was partially remediated in 1982. The remaining creek remediation
was completed in 1992 under a Consent Order. Pilot testing was conducted in 2002 and
construction of the full scale SW Plant Ground Water Recovery System (GWRS) remedy
began in 2004. The GWRS construction was completed in September 2005 and is in
operation. In 2007, DuPont performed a GWRS overhaul and replacement.
• Blast fractured bedrock trenches that were installed in the SW plant area to optimize
groundwater collection in that area have greatly increased hydraulic containment and pump
rates. The GWRS upgrades replaced the original steam stripper and added a therm-ox unit to
treat off-gasses to handle additional flow from trenches creating greater treatment reliability
and reducing system down time. Over 133,000 pounds of organic contaminants have been
removed from groundwater since startup through 2009 by the GWRS and Olin pumping
systems.
Vanadium Corporation
$ A Record of Decision compiling the results of operable units OU#l, OU#2, and OU#3 was
issued in March 2006.
$ Remedial actions were completed at OU#l and OU#2 in 2007.
$ The Remedial Design for the last remaining operable unit, OU #3, to address remaining
surficial waste and slag was completed in 2007. The remedial action for OU#3 should begin
in the Spring of 2010. Estimated Completion Date: December 2010
Buffalo Color Corporation Site
$ In March 2005 Honeywell (a potentially responsible party) entered into an Order on Consent
to address groundwater contamination at the site by designing and installing a groundwater
collection system. Design was completed in 2005. The construction was completed in 2007.
9
-------
$ Honeywell performed a bulk chemical removal at the Site starting in December 2005 and it is
presently complete. The site though is not considered RCRA clean. The site has been
transferred from NYSDEC's RCRA unit to the Division of Environmental Remediation.
$ Honeywell has completed their RI/FS for Areas A,B,C and E. as part of the June 30, 2006
Consent Order. The fieldwork began in January 2007 with a draft report Remedial
Investigation Report submitted in September 2007. The RI/FS was completed in 2008. As a
result of the RI/FS, a Brownfield Cleanup Plan application was submitted and was approved
by the NYSDEC in April 2009. The Remedial Work Plan was approved in May 2009.
Demolition of the plant buildings began in late 2009 and will continue through early 2010.
Design activities will continue into 2010. Remedial Action work is expected to be
performed in 2010/11.
Bethlehem Steel Corporation (BSC) Site
$ BSC has completed the field work for the site investigation, and has prepared Resource
Conservation and Recovery Act Facility Investigation (RFI) and human health risk
assessment reports. These had been delayed due to negotiations over the scope and the need
to collect additional data, but were finally submitted in December 2004.BSC completed
limited remedial technology studies for two areas that appear to be the primary sources of
groundwater contamination at the facility (the Acid Tar Pits and Coke Oven Areas). The EPA
and NYSDEC found the studies to be technically flawed and of limited value. BSC continues
to study various potential remedial technologies.
$ In 2004 DEC approved an interim corrective measures plan for the remediation of the Benzol
Plant Area (i.e., the Coke Oven Area). In November 2004, NYSDEC issued a consent order
to administer this project. Recovery-well installation was completed in December 2004. The
system, which began operating in April 2005, includes LNAPL recover and groundwater
collection and treatment.
$ In 2005, Tecumseh Redevelopment Inc., a subsidiary of ISG and Mittal Steel, submitted
brownfield applications to NYSDEC for two more parcels containing about 300 acres. Since
any future CMS or CMI activities will require a new order, permit or other agreement,
NYSDEC is currently negotiating a corrective action order with ISG for this work. Numerous
areas of the site that are not regulated under the RCRA program have been proposed for
clean-up under NYS Brownfield program.
In one of these areas, eight windmills were constructed at the site under the Brownfield
Cleanup Program in 2007. A Corrective Measures Study (CMS) Order with Tecumseh
Redevelopment (current owner) was signed in June 2009. The results of this study should
be complete by the end of 2010.
10
-------
Frontier Chemical. Royal Avenue
$ In January 2001 the site was referred for RI/FS action under the NY State Superfund program.
The Focused Remedial Investigation was begun in 2001. The RI/FS for the soils and upper
bedrock (OU#l) was completed in early 2004. A Record of Decision (ROD) for site soils and
upper bedrock groundwater (Operable Unit (OU) #1) was issued in March 2006. It requires
the excavation and off-site treatment/disposal of contaminated soil source areas with
control/treatment of overburden and upper bedrock groundwater. A Consent Order for the
investigation and evaluation of the deeper bedrock groundwater (OU#2) and further
investigation of subsurface soils to delineate on-site contamination was signed on August 15,
2008. The RI/FS for OU#2 and pre-design sampling activities are underway. Subsequent
design, construction and operation of the remedy will either be done by the PRPs under an
Order, or by the NYSDEC using the State Superfund program. Estimated Start of RA:
Late 2010/2011.
Mobil Oil
$ Exxon/Mobil has entered the Brownfield Cleanup Program to complete subsequent
remediation activities under a BCP Agreement with NYSDEC dated April 3, 2006. In spring
2006 a Conceptual Site Plan (CSP) was approved by the State. The Site has been divided into
nine geographic areas for the purpose of assessing environmental conditions and reporting the
results of area-specific activities according to the nature of their historical primary
operations. Now that sitewide remedial investigation is complete, the site was divided into
five OUs based upon the anticipated phasing of subsequent remedial actions considering
environmental media to be addressed, potential remedial approach and geographic areas. The
remaining OUs are:
OU#2: Soil, groundwater and any free product located to the north of Prenatt St. and south of
Elk St.
OU#3: Main Free Product Plume and contaminated soil and groundwater south of Prenatt
Street.
OU#4: Soil and groundwater within the Eastern Tank Yard Area (ETYA).
OU#5: Buffalo River sediment impacted by Exxon/Mobil historical operations
In Spring 2006 the State executed a Brownfield Cleanup Agreement and approved a
Conceptual Site Plan addressing the various operable units of the plant site. OU#l, which
addressed the soil impacts in the Elk Street Properties Area determined to be attributable to
the former Tank 60 release from 1976, was completed in 2007.
Estimated Completion Date: December 2011

Estimated Remediation Costs
Estimates of the cost of remediation are available for most of the 26 priority hazardous waste sites.
Where available, individual project costs for each site are provided for quick reference in summary
tables located in Appendix A of this report. As indicated below, the total costs incurred to date are
estimated to be at least $442,869,000. Total future additional remedial and O&M costs are estimated
to reach at least $262,150,000.
Based on available estimates for 21 sites, following is the total amount incurred to date (costs for the
remaining 5 sites are unavailable):
Federal $ 39.832 million
State $ 7.425 million
PRPs $ 395.772 million
Total $ 443.029 million
Based on available estimates for 12 sites, the total additional remedial and O&M costs expected in
the future are as follows (costs for the remaining 14 sites are unavailable):
Federal $ 1.875 million
State $ 0.710 million
PRPs $ 259.564 million
Total $ 262.149 million
The estimated costs to date cannot be compared to the estimated costs expected in the future, because
different sites are included in the estimates. It is also difficult to compare the relative contributions of
federal, state, and PRP expenditures, because cost information for some sites was incomplete (e.g.,
some sites may have been able to provide federal or state costs but not PRP costs, and so on).
However, the cost information does provide a sense of the magnitude of U.S. expenditures for
hazardous waste site remediation in the Niagara River basin.
Future Challenges and Opportunities for the NRTMP
A number of related initiatives are underway that present opportunities for possible merging or
coordination with other activities and resources. These current initiatives include coordination of the
NRTMP with the Niagara and Buffalo River AoC RAP process; future monitoring, data collection
and analysis; and remediation of additional pollutant sources.
Area of Concern (AoC) RAP and Delistings - The AoC delisting initiative is a top priority for the
Four Parties over the next several years. The Beneficial Use Impairments (BUIs) listed by both the
binational Niagara River AoC and Buffalo River AoC are believed to be based on impacts of toxics
chemicals which have been closely linked to the hazardous waste site inputs to the rivers. Formal
coordination of the NRTMP and AoC RAP mechanism would achieve greater resource efficiency and
public understandings.

-------
Niagara River Area of Concern Remedial Action Plan: The Niagara River Area of Concern (AoC),
located in Erie and Niagara counties, extends from Smokes Creek near the southern end of the
Buffalo Harbor and north to the mouth of the Niagara River at Lake Ontario. In 1994, the NYSDEC,
through an appointed Remedial Advisory Committee (RAC), completed and published a Remedial
Action Plan (RAP). To date, the RAC has identified 5 BUIs to be addressed and 2 BUIs needing
further assessment (see Table 3). Past municipal and industrial discharges and hazardous waste
disposal sites have been a source of contaminants to the Niagara River which have been linked to
several BUIs in the AoC. Of the 26 priority waste sites discussed in this report, 21 sites are located
directly in the Niagara River watershed basin. Of these 21 sites, nineteen sites have completed
remedial construction and two sites (Frontier Chemical Royal Ave. and Vanadium Corporation) have
remedial actions currently underway. It is understood by the Four Parties that the NRTMP initiative
contributes greatly towards the restoration of wildlife and aquatic habitats, re-designation of
beneficial uses from impaired to un-impaired, and the ultimate de-listing of the Niagara River AoC.
Therefore, it is noted by the joint agencies as an example of bi-national cooperation on the Niagara
River and as an important contribution to the RAP process in the AoC. It is expected that RAP
implementation will progress at an aggressive pace over the next several years while the NRTMP
works towards removing all remaining toxic pollutant inputs to the river.
Buffalo River Area of Concern Remedial Action Plan: The Buffalo River AoC is located in the
City of Buffalo in Western New York State. The river flows from the east and discharges into Lake
Erie near the head waters of the Niagara River. In 1989, a RAP was prepared by the NYSDEC for
the Buffalo River AoC. The NYSDEC acted as RAP coordinator from 1989 - 2005 until the U.S.
EPA Great lakes National Program Office selected the Buffalo Niagara Riverkeeper (BNR) as RAP
implementation lead coordinators. To date, the BNR has identified 6 BUIs to be addressed and 3
BUIs needing further assessment (see Table 4). Of the 26 priority waste sites discussed in this report,
one site (Bethlehem Steel Corporation Site) has direct local impacts to Buffalo Harbor to the north
and on the western boundary of Lake Erie and four sites (Buffalo Color Corporation Site, Buffalo
Color - Area D, Mobil Oil, and Iroquois Gas-Westwood Pharmaceutical) have direct local impacts to
the Buffalo River. These five sites are part of the NRTMP 26 priority sites since they in turn have
impacts to the head waters of the Niagara River (see Figure 1). Two of the sites (Buffalo Color-Area
D and Iroquois Gas-Westwood Pharmaceuticals) have completed remedial construction and the other
three sites (Mobil Oil, Buffalo Color Corporation Site, and Bethlehem Steel) have remedial actions
currently underway. Bethlehem Steel and Mobil Oil operate interim remedial systems while final
remedial actions are completed. These NRTMP waste sites are listed as part of the Buffalo River
RAP to be addressed towards restoring beneficial uses. Restoration and re-designation of the BUIs in
Lake Erie, Buffalo and Niagara Rivers will ultimately result in delisting of the Buffalo River AoC as
well as the Niagara River AoC.

TABLE 3
TABLE 4
Niagara River AoC Beneficial Use Impairments
Of the 14 beneficial uses, five are impaired for the
Niagara River:
1. Restrictions on fish and wildlife
consumption
2. Fish tumors or other deformities
3. Degradation of Benthos
4. Restriction on dredging activities
5. Loss of fish and wildlife habitat
In addition, the designation of two beneficial uses need
further assessment to determine their status:
1. Degradation of fish and wildlife
populations
2. Bird or animal deformities or
reproductive problems
Buffalo River AoC Beneficial Use Impairments
Of the 14 beneficial uses, six are impaired for the
Buffalo River:
1. Restrictions on fish and wildlife
consumption
2. Fish tumors or other deformities
3. Degradation of aesthetics
4. Degradation of Benthos
5. Restriction on dredging activities
6. Loss of fish and wildlife habitat
In addition, the designation of three beneficial uses
need further assessment to determine their status:
1. Tainting of fish and wildlife flavor
2. Degradation of fish and wildlife
populations
3. Bird or animal deformities or
reproductive problems
Future Monitoring, Data Collection and Analysis - In addition to the effectiveness of pollutant
removal at the waste sites themselves, it is important to note that there are three components to the
NRTMP monitoring plan: Environment Canada (EC) Upstream/Downstream (U/D Program); Bio-
monitoring (mussels, young-of-year fish, wildlife); and source track down & analysis screening.
Anticipated in 2009/10, the Niagara River Secretariat will prepare a trend analysis report covering the
past 20 years of data collected in-water and compare concentration inputs at Fort Erie and Niagara-
on-the-Lake. The U/D Program is expected to continue to be a valuable tool for assessing overall
progress and future priorities as explained below in more detail.
NRTMP Monitoring Program Plan: The NRTMP's primary mechanism for measuring
improvements in water quality is the Environment Canada (EC) U/D Program. The U/D Program
measures approximately 50 organic chemicals and includes the 18 NRTMP Priority Toxics in the
dissolved and particulate phases at the head (Fort Erie) and the mouth (Niagara-on-the-Lake) of the
Niagara River where it enters Lake Ontario (Figure 2). Water quality data is collected year-round
and EC publishes a formal U/D Program report on every ~2 years of data. The most recent U/D
Program report was published in 2007 and includes data from 2004/2005. Since 1987, high quality
US and Canadian government monitoring program information provide clear evidence of reductions
for most of the 18 Niagara River Priority Toxics in water, sediment and biological indicators in the
range of 50% or greater by the 1996 target year. The Niagara River Secretariat 20-year data trend
report, expected in 2009/10, should be a useful tool for setting priorities such as future track down
and analysis studies to identify potential new sources of contaminants, new emerging chemicals, and
NRTMP management strategies for reducing these chemicals.

Remediation of Additional Pollutant Sources - The 1989 EPA/NYSDEC Hazardous Waste Site
Report identified the NRTMP's original 26 waste sites as highest priorities due to their potential to
contribute over 90% of the total toxic chemical loadings to the Niagara River. These 26 sites and the
estimated loadings were based on earlier studies and often on preliminary data. Although these 26
sites were of top priority for the NRTMP, numerous investigations and remediations at other site
areas, some consisting of multiple individual sites, were being addressed under New York State's
remedial programs. The additional efforts by NYSDEC and EPA have included six additional sites
described below now known to be significant contributors of toxic contamination to the river but for
which insufficient data existed in 1989 to include them in the NRTMP. The NRTMP is considering
the need for a revised assessment of the toxic contamination contributions from all known hazardous
waste sites to the river using current methods and techniques. For a quick reference, see the summary
tables for these projects located in Appendix B of this report. Also, detailed site information for all
sites can be found in NYSDEC's Environmental Site Remediation Database website located at
http://www.dec.ny.gov/cfmx/extapps/derexternal/index.cfm?pageid=3 .

-------
Fourth Street Site - NYSDEC #915167
The site is located on Fourth and Village Court streets in the City of Buffalo and is located in a mixed
residential, commercial, and recreational setting approximately 1500 feet from the Lake Erie
shoreline. The Citizens Gas Works operated on this property staring from the early 1900's.
From 1934 to 1958, a portion of the property was also used by Greyhound Bus Company to service
its vehicles. During a site evaluation in 1992 black tar material was found in one area of the property.
Soil/tar and groundwater samples were tested during the investigation and results showed contained
up to 3300 ppm of benzene, 3000 ppm of toluene, 2700 ppm of xylenes, 3000 ppm of phenolic
compounds, and 53,000 ppm of PAHs. Site groundwater also exceeded groundwater standards for
benzene, toluene, xylenes, PAHs, and phenolic compounds. In August 1996, NYSDEC/NYSDOH did
additional testing which detected surface soil samples containing up to 420 ppm of PAHs.
The tar material was found to be a hazardous waste as it failed TCLP for benzene. The City of Buffalo
conducted an investigation and submitted the RI/F S report in January 2001. A Record of Decision (ROD)
was issued in 2001 requiring the removal of all contaminated tar materials from the site. The
construction of the remedy began in July 2005 and was completed in early 2006. The site has entered the
long term site management phase. Implementation of the environmental easement and reclassification of
the site is expected in 2010.
Former Buffalo Service Center - NYSDEC #C915194
This site is the location of a former Manufactured Gas Plant (MGP) which was operated by various
companies from 1848 to 1948. The site was initially investigated by the owner - National Fuel Gas
during the period 1989 to 2004. The investigation confirmed the presence of MGP wastes (containing
benzene, toluene, ethylbenzene, xylenes, polycyclic aromatic hydrocarbons, total cyanides) in soil
and groundwater at the site. In June 2005 a volunteer applied to the Brownfield Cleanup Program to
remediate the site in preparation for building an office building. The site remediation consisted of
excavation and off-site disposal of contaminated soils above the predetermined cleanup levels and
backfilling with clean soil/material. Work began in summer 2005 and was completed in early 2006.
An environmental easement requiring a Site Management Plan was filed on September 7, 2006 in the
Erie County Clerk's office. Remaining groundwater contamination will be monitored by an Operation
& Monitoring Plan. A Certificate of Completion was issued on November 30, 2006. The cleanup has
resulted in the construction of an approximately 350,000 square foot Health Now building by Duke
Realty at the remediated site. Groundwater at the site is being monitored in accordance with the Site
Management Plan, dated October 2, 2006.
Alltift Landfill - NYSDEC #915054
This site is a former landfill that was previously used for the disposal of domestic and industrial
wastes. Environmental studies documented surface and groundwater contamination. According to
Phase II Investigation documentation, Allied Corp. (National Aniline Division) disposed
miscellaneous organic chemicals, chrome sludge, copper sulfate, nitrobenzene, monochlorobenzene,
and naphthalene on a monthly basis in the landfill. A smaller landfill containing automobile shredder
wastes, demolition debris, fly-ash and sand wastes was situated on top of the older chemical waste
landfill. This smaller landfill was operated between 1975 and 1984. A Consent Order for the
completion of a RI/FS of the site was signed by Allied Signal in 1991.
16
-------
A RI/FS report was submitted in 1992 indicated that groundwater and the ponds adjacent to the site
were impacted by the landfill. Contaminants of concern include metals, pesticides, PCBs, chlorinated
solvents and PAHs and would be tributary to the Buffalo River drainage basin.
A Record of Decision (ROD) was signed on March 27, 1995 requiring: capping, waste consolidation,
wetlands restoration, and groundwater collection. Remedial action began in 2004 and was completed
in 2005. An operation, maintenance and monitoring plan was put in place in 2006 and
implementation is ongoing.
Steelfields Site - NYSDEC # V00619
The Steelfields Site is located in the City of Buffalo adjacent to the Buffalo River. The site is comprised
of four distinct areas based on the historical operations that occurred there. These areas are known as:
Area I-Republic Steel Area, Area II-Donner-Hanna Coke Plant, Area III- Republic Steel Warehouse, and
the Area IV-Coke Storage Yard. The former above-ground facilities were demolished previously by the
LTV Steel Company. Today the site is largely vacant except for the former "August Feine" building
located just north of Area II where a newly constructed containment cell exists. In 2006, Area IV was
separated from the site and entered into the Brownfield Cleanup Program as Steelfields Area IV
Site#C915204. Area IV is also listed on the NYS Registry as a Class 3 hazardous waste site under Site
#915017. The Steelfields site was the location of a former steel and coke-making facility. The site had
significant amount of fill material (2 to 20 feet in depth) from past activities. The fill consisted of waste
slag and coke, in addition to significant quantities of chemically contaminated soils from past disposal
practices on the site. LTV Steel, the previous Volunteer for this site (V00133) went bankrupt in 2000. In
October 2002 Steelfields Ltd. purchased the site out of bankruptcy. Steelfields Ltd. entered into the
Voluntary Cleanup Program and agreed to undertake the necessary investigation and cleanup of the 218
acres. A work plan outlining the work to be performed was approved in 2002. Remedial work was
completed on approximately 90 acres known as Area 1 in 2004. Remedial work was completed in all
areas of the site by October 2007. Declaration of Covenants and Restrictions were filed for Area I in
2007 and for Areas II & III in 2008. Long term Site Management is ongoing.
Niacet Corporation — NYSDEC # V00373
The Niacet facility, formally a Union Carbide Corporation facility, is located on 19.42 acres at the
intersection of 47th St and Pine Ave in the City of Niagara Falls. The facility is an active manufacturing
facility first constructed in 1925 and operated as the Niacet Chemical Company. The plant originally
produced acetaldehyde, paraldehyde, aldol and crotonaldehyde. The production of acetic acid was begun
in 1928 and the manufacture of sodium acetate and other acetates began in 1935. Vinyl acetate
production was added in 1937. In 1957 the facility name was changed to Union Carbide Corporation. The
plant produced a variety of wastes including mercury/aluminum sludge, 2-ethylexoate, zincacetate, acetic
acid, acetate salts and overflows from the vinyl division. In 1978 Niacet purchased the property from
Union Carbide Corporation and currently manufactures specialty chemical products for food,
pharmaceutical and industrial applications. A site investigation was completed in 2002 indicating the
presence of mercury contaminated soil. A supplemental site investigation was completed in March 2006.
A draft Remedial Action Selection Report (RAS) was submitted in November 2006. The draft RAS was
not acceptable and the Department requested revisions to the RAS were requested. Resubmission of the
RAS is pending resolution of the contaminated soil disposal characterization and classification issues.

-------
Spaulding Fiber Site — NYSDEC #915050/E915050
The 46 acre Spaulding Composites Site is located at 310 Wheeler Street in the City of Tonawanda.
Spaulding manufactured composite laminates and vulcanized fiber between 1911 and 1992 at this now
abandoned facility. The paper used to produce vulcanized fiber, and many of the phenolic resins used in
the production of the composite laminates, were also manufactured on site. Site drainage and contaminant
transport was tributary to the Niagara River through the municipal storm sewer system. All
RI/FS/Corrective Measure Studies have been completed for RCRA/Superfund portions of the site. The
Record of Decision (ROD) for this site was issued in March 2003. Seventeen Solid Waste Management
Units (SWMUs)within approximately 2.5 acres of property around the plant buildings were identified
(included in four separate operable units) as requiring remediation as a part of the SSF project; the rest of
the property is being addressed as part of an Environmental Remediation Project (ERP). Remediation of
OU#2 was performed as an IRM to address PCB contamination of surface and subsurface soils.
Remediation of OUs (#1, #3 & #4) is underway and is scheduled to be completed by the Summer of
2010 under the State Superfund Program. The RI/F S for the ERP portion of the site was completed and a
no- action ROD for the project for OU#7 was issued in March 2009. Design documents for OUs (#5 &
#6) have been completed and the remedial work is also expected to be completed by the summer of 2010.
