The Buffalo River Restoration Partnership, also known as the Great Lakes Legacy Act Project Coordination Team, is working on the cleanup of the contaminated sediment in the Buffalo River. The partnership includes the U.S. Environmental Protection Agency (USEPA) Great Lakes National Program Office, the USEPA Region 2, the U.S. Army Corps of Engineers, Honeywell, Buffalo Niagara Waterkeeper, the New York Department of Environmental Conservation, the City of Buffalo, and Erie County.

What is the timeframe of the cleanup?

計劃發生在兩階段的河流。Phase I dredging is fully funded and began in August 2011 and will continue through November 2011. The U.S. Army Corps of Engineers is taking the lead on the dredging of the federal navigation channel (or center of the river) in 2011, which is being funded by the Great Lakes Restoration Initiative. Phase II of the project is under remedial design, with a proposed start date in 2012. Phase II is the cleanup of contaminated sediments outside of the navigational channel, including side slopes. Phase II dredging will be lead by the U.S. Environmental Protection Agency Great Lakes National Program Office under the Great Lakes Legacy Act and take approximately two years (through 2013), which will include habitat restoration.



Is the funding for all phases of dredging secure?



到目前為止已經花了超過600萬美元Remedial Investigation/Feasibility Study and Remedial Design. There are no guarantees that Phase II dredging will be implemented, however the Buffalo River Restoration Partnership is committed to the restoration of the Buffalo River. Significant personnel time and resources has been dedicated to the effort for more than seven years.



Will dredging impact recreation on the river?

美國軍隊的工程兵團2010年期間的環境評估表明,預計將對水和下水設施的項目沒有產生不利影響,疏浚不應該對飲用水產生任何不利影響。I級沉積物的評價包括在內對水牛港,GLRI的發現沒有重大影響和環境評估(U.S. Army Corps of Engineers 2010). The evaluation of the Phase II sediment will be included in the U.S. Army Corps of Engineers Environmental Assessment. The City of Buffalo is constantly monitoring intakes to ensure high quality drinking water. Multiple controls are in place to ensure protection of drinking water throughout phases I and II. Although dredging causes a short-term disruption of sediment in the river, this project will use four primary methods to limit this occurrence. First, the dredging will occur at a slow, controlled pace. Second, a closed clamshell bucket will be used to dig the sediment; compared to other buckets, it has a smoother, tighter close. Third, barges will be prohibited from overflowing excess water into the river. Finally, dredging will not occur during exceedingly high river flow events.

Although there will be temporary resuspension of sediment at the dredging site, analyses by the Corps indicates degradation is not expected in the quality of the surface water. The U.S. Army Corps of Engineers conducted modeling to evaluate the impacts of Phase I dredging and did not identify long-term impacts to surface water quality. They are currently conducting similar modeling for Phase II. The results of their modeling will be used to identify if additional engineering controls will be needed during dredging to minimize short-term water quality impacts. Sediment sampling was performed to provide an estimate of the contaminant concentrations in the surface sediment both before and after dredging. The existing surface concentrations were used to identify the areas to be dredged. The environmental dredging in these areas will continue until the criteria in sediment quality guidelines have been achieved. The 2010 U.S. Army Corps of Engineers Environmental Assessment (see Q9) recommends that in areas of the Ship Canal with the potential to release higher concentrations of soluble copper, that under the best of conditions the dredge production rate should be restricted to about 3000 cubic yards per day. Care would be taken to minimize the disturbance of the sediment bed by minimizing the number of lifts used to achieve the desired channel depth. In addition, barge overflow and bucket draining would be avoided. These measures will help to minimize the release of copper to the water column during dredging. The U.S. Army Corps of Engineers Engineer Research and Development Center has conducted similar evaluations for the U.S. Environmental Protection Agency Great Lakes National Program Office to ascertain what, if any, specific measures need to be implemented to ensure that Phase II dredging is also performed to reduce the potential for contaminant releases to the water column. This evaluation is pending and scheduled to be completed in 2011.

After dredging is done, what is planned to improve water quality?


Buffalo River is at the receiving end of a large watershed. Once the contaminated sediment is removed, what will keep the river from again filling with contaminated sediment from the watershed?

Comprehensive chemical analyses within the river and the upper tributaries have shown that sediment being carried downstream is much cleaner than the historical sediment currently below the surface of the Buffalo River.

After the dredging, will the sediment be clean enough for other beneficial uses?


Is placement of dredged sediment from Phase I and II in the Confined Disposal Facility (CDF) safe?

Yes, the U.S. Army Corps of Engineers has determined that placement in the CDF is and will be protective of human health and the environment. All dredged sediment will be placed in the existing U.S. Army Corps of Engineers CDF 4 located in the Outer Buffalo Harbor adjacent to the Buffalo Harbor South Entrance Channel. The U.S. Army Corps of Engineers Engineer Research and Development Center performed two separate evaluations of the various tests of the sediment to be dredged under Phases I and II. The conclusions of these evaluations indicate that internal concentrations of contaminated pore water or carrier water will not cause lake contamination. Also, additional and ongoing upgrades have been made to ensure integrity of CDF walls.

How does the dredged sediment in Phase I differ from other material in the Confined Disposal Facility (CDF)?




Will there be ongoing water quality monitoring during dredging operations? Who will perform the monitoring and who will pay for it?

Water quality monitoring is not planned for Phase I. Prior to dredging, impacts to the water column due to sediment resuspension, including suspended solids and contaminant concentrations, are assessed through predictive lab tests and modeling. Modeling is based on sediment contaminant concentrations, partitioning parameters and geotechnical properties. Results are compared to federal water quality criteria established for the protection of aquatic life to ascertain the potential for adverse risk. The 2010 Environmental Assessment (see Q9) for Phase I indicates there is the potential for short-term risks to aquatic life from water column impacts during dredging. Methods to reduce short-term risk are described in Q7. Short-term adverse affects must be compared to the long-term improvements in overall water quality resulting from to the permanent removal of contaminated sediments from the aquatic system. Water quality monitoring is planned for Phase II and will be incorporated into the project cost. Final construction monitoring requirements will be worked out by the state and federal regulatory agencies during the project permitting process. Responsibilities for monitoring activities will be determined during design and contracting activities.

Will there be long-term monitoring of the river after dredging is completed?

階段I沒有計劃長期監測。對於第二階段,目前正在製定疏浚後期(3-5歲)的長期監測計劃作為補救設計的一部分。水牛河補救措施計劃還將製定延長的長期監測協議(> 5年),並將在最終確定一次公眾審查。根據每個計劃的具體目標,可以對以下一個或多個措施進行監測 - 沉積物化學/毒性,水質,棲息地質量,魚類組織濃度和底棲群落。

The Buffalo River Restoration Partnership is in close contact with various shoreline property owners including the operators of the marinas. We are working with the owners on the dredging schedule to minimize impact on the slip owners’ usage of the river. Due to the magnitude of sediment to be removed, we cannot guarantee whether there will be restrictions or impacts on the access to slips at certain times of the year.


Urban rivers often contain large amounts of debris and experienced dredging contractors are accustomed to dealing with this. The dredges and supporting equipment used is sufficient for clearing large debris and properly disposing of it. The Buffalo River Restoration Partnership will continue to communicate and coordinate with police as we move through remedial design and construction.





There are several sites that are very environmentally hazardous along the banks. Have you identified them all and fixed them so they don’t leak back into the river?

Over the years many hazardous waste disposal sites along the Buffalo River have been identified and either are being addressed through New York State’s cleanup programs or already have been remediated. These sites include Sovereign Specialty Chemicals, Steelfields (Former Republic Steel and Former Donner-Hanna Coke), Buffalo Color, and Exxon Mobil. Remedial actions at these sites were designed to remove, treat, or contain contamination and to prevent the migration of residual contaminants to the river. In the future, as information becomes available, the New York Department of Environmental Conservation (NYDEC) will continue investigations to ensure upland sites do not impair the Buffalo River.
