Fact Sheet
Draft Onondaga Lake Sediment Management Intermediate Design Submittal and Associated NYSDEC Comments Available for Review

Onondaga Lake Bottom Site (#7-34-030)
Onondaga County - June 2010


The draft Onondaga Lake Sediment Management Intermediate Design (dated February 2010) has been submitted by Honeywell and reviewed by the New York State Department of Environmental Conservation (NYSDEC) and the United States Environmental Protection Agency (EPA). This document provides intermediate-level design information on the management of sediments to be dredged as part of the Onondaga Lake remedy. The design document and NYSDEC's comment letter associated with the document (dated May 29, 2010) are available for review in the locations listed on page four

Sediment Management Intermediate Design Submittal for the Onondaga Lake Bottom Site

The Onondaga Lake remediation plan was separated into four designs in order to advance critical design components so that dredging activities can begin as scheduled in May 2012.

This design document describes how the dredged lake-bottom sediments will be pumped through a double-walled pipe up to the Sediment Consolidation Area (SCA) located on Wastebed 13, how the sediments will be managed within the SCA, and how water that drains from the sediments will be collected and transported to the SCA Water Treatment Plant. Comprehensive efforts to protect the public's health and safety are an important part of the work to restore Onondaga Lake. Health and safety plans are reviewed by the NYSDEC and the New York State Department of Health and are incorporated in to every stage of the restoration.

The design team will continue to work with the community to ensure that the health and safety of the surrounding community and environment is maintained throughout the remedy. A dredging and SCA operations health and safety plan is being developed and will be available for public review and comment in the summer of 2011 and will include:

  • Site Security & Community Health and Safety Plan
  • Air Quality Monitoring and Mitigation Plan
  • Spill Contingency Plan

Components of the Onondaga Lake remedy that are discussed in the Sediment Management Intermediate Design include:

  • Transport of sediments in a slurry (sediment/water mixture) from the shoreline through a double-walled pipe to the Sediment Consolidation Area (SCA)
  • Pre-processing of the sediment slurry prior to being pumped into the geotextile tubes (e.g., screen of larger material, sand separation, addition of polymer to aid in the dewatering of the sediment slurry within the geotextile tubes)
  • Use of geotextile tubes for dewatering of sediment slurry
  • Management of stormwater and water draining from geotextile tubes
  • Management of debris removed from the lake to facilitate dredging and capping
  • Traffic Management Plan
  • Noise Abatement Plan

Water draining from the geotextile tubes will be collected and pumped to the Sediment Consolidation Area Water Treatment Plant that will also be located in close proximity to the SCA. The design of the Sediment Consolidation Area Water Treatment Plant is discussed in separate design documents and can be accessed at the locations listed on page four.

Dredging debris management will consist of recycling, placing the debris within the SCA, or disposing the material off-site depending on the nature of the debris.

Next Design Submittal

Public comments will be incorporated into the next design submittal related to these elements of the remedy, the Draft Sediment Management Final Design, which is scheduled to be submitted during January 2011.

Public Participation

Public input is encouraged throughout the design process. In May, 2009 the DEC released for public review the draft Onondaga Lake Dredging, Sediment Management & Water Treatment Initial Design Submittal. The NYSDEC issued a fact sheet announcing the availability of the document. In May, 2009, as part of the Onondaga Lake bottom remediation program Citizen Participation Plan, the NYSDEC formed a Lead Community Participation Working Group. This group, made up of volunteer community members, meets on a regular basis to ensure the public has a forum to contribute information, opinions, perspectives, and recommendations about the program.

DEC will consider public input on the draft Sediment Management Intermediate Design received by August 16, 2010 as we move ahead with the remedial design process.

Project Contact List

The NYSDEC intends to use electronic mailing as much as possible for environmental and economic reasons. If you would like to begin receiving information electronically on the Onondaga Lake Bottom site, such as this fact sheet, please sign up for the Onondaga Lake News email list by visiting the NYSDEC website. Once signed up, please also notify the NYSDEC at via email to stop receiving printed copies in the mail.
