DEC Releases Report on Hudson River Cleanup

The New York State Department of Environmental Conservation (DEC) has released an independent report on the U.S. Environmental Protection Agency’s (EPA) review of the cleanup of PCB contamination in the Hudson River.

Using EPA’s guidance, DEC found out that the cleanup is not protective of the public or the environment. In an effort to improve the cleanup, New York State sent a letter with the report to EPA prior to EPA’s anticipated release of its Five Year Review in 2017.

In the report, DEC determined that high concentrations of PCBs remain in fish in portions of the Hudson River resulting in human health and ecological risks in excess of EPA’s acceptable risk range.

DEC also found that, as highlighted in a previous Five Year Review, higher than anticipated sediment concentrations will remain after dredging, indicating that the targeted reductions in fish PCB concentrations will not be achieved in the time frames EPA relied upon when choosing the remedial plan for the Hudson River.

It’s simple. DEC is calling on the EPA to finish the job and hold GE accountable for cleaning up the Hudson River,” said DEC Commissioner Basil Seggos. “If EPA won’t do the job and protect New Yorkers and the environment, DEC is ready to step in and lead.”

DEC developed the report using EPA’s basis for selecting the remedy and the data and information gathered during the dredging project, which reveal cancer and non-cancer health risks well above the acceptable risk range for people who ate fish from both the Upper Hudson River (between Hudson Falls and Troy) and the Lower Hudson River (from Troy south to Manhattan). Risks to ecological receptors such as fish-eating animals were also above EPA’s acceptable range.

In addition, DEC considered EPA’s rationale for selecting the dredging remedy. EPA chose the dredging remedy, under which significant amounts of PCBs would be removed from the sediments of the Upper Hudson, primarily because of the time estimated to achieve targeted fish PCB concentrations.

Specifically, EPA stated that a delay of 10 years in reaching target fish concentrations of 0.4 mg/kg within 5 years of the completion of dredging and 0.2 mg/kg within 16 years of the completion of dredging was unacceptable.

This delay formed the basis for EPA’s rejection of alternative remediation methods. Based on data collected to date, it is clear that the dredging performed will not meet these targeted fish PCB concentrations, and EPA will not be able to deliver on the projected benefits to public health and the environment from this cleanup unless additional actions are undertaken, said DEC in the release.

DEC recently called on EPA to perform additional sampling in order to complete a detailed evaluation of the dredging, including increasing the sampling of sediment and fish tissue to the scale and frequency necessary to optimize the remedy through further remedial work in order to achieve the targeted fish PCB reductions originally identified. DEC also recommends that EPA expand the investigation of remedial efficacy to include the portion of the site between the Federal Dam at Troy and the Battery in New York City.

According to DEC, this work is necessary to determine the nature and extent of PCB contamination in the sediments, water, and biota of the Lower Hudson, and to evaluate remedial alternatives to address the currently uncontrolled and unacceptable risks to human health and the environment.

EPA currently plans to collect only 375 samples, or fewer than 10 samples for every mile of river. DEC has concluded that at least 1,800 samples are needed to have the statistical power to draw timely, science-based conclusions from the sampling results.

Under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and the National Contingency Plan (NCP), EPA is required to monitor effectiveness of the remedy to affirm that it is meeting the goals set by the Record of Decision (ROD).

In March, EPA committed to perform a five year review of the remedy, which it expects to issue in the spring of 2017. EPA must take additional remedial action if the remedy fails to meet the goals required by the ROD, including reducing PCB levels in fish within the timeframe EPA originally anticipated.

3rd International Congress Hydraulic Engineering Structures and Dredging

Russia’s leading maritime industry Media Group PortNews (www.portnews.ru) holds a traditional annual Congress “Hydraulic Engineering Structures and Dredging” in Moscow. 

The two-day Congress includes the 7th International Forum of Dredging Companies and the 3rd Technical Conference “Modern Solutions for Hydraulic Engineering”.

Infrastructure development is among the real sources of Russia’s economy growth. Construction of port facilities and new hydraulic engineering structures on the country’s inland waterways constitute an essential part of all infrastructure projects. It is important to take into account the best international practices to implement these projects effectively.

The program of the Congress will be devoted to the latest technologies for dredging and hydraulic engineering works. Speakers and delegates will refer to real projects to discuss specifics features of dredging works, as well as dedicated fleet and equipment involved.
