| Sydney Tar Ponds and Coke Ovens site (Muggah Creek Watershed Cleanup) | |
| Start Date: | 1/1/1980 |
| End Date: | n/a |
| Location: | Sydney, Nova Scotia (Sydney Tar Ponds) Sydney Harbor estuary and Muggah Creek |
| Project Scale: | Active or Inprogress. |
| Media Treated: | Soil. |
| Clean up of Site Involved: | Site Characterization & Assessment, Monitoring. |
| Site Condition: | The toxic wastes including tar and gases from the coke ovens, benzene, kerosene, and naphthalene.More than 80 years of this type of coke-oven operation left the ground water and surface water in the area seriously contaminated with arsenic, lead and other toxins. It also led to the accumulation of some 700,000 tonnes of chemical waste and raw sewage, 40,000 tonnes of which are PCBs (Polychlorinated Biphenyls). |
| Proposed Site Usage: | none - strictly cleanup |
| Reasons for Success: | Public Participation Plan (January 2002 to May 2002) - JAG gets input from over 600 members of the community on issues that experts should bear in mind when cleanup options for the sites are evaluated and on possible future uses of the sites.Remedial Action Evaluation Report (January 2002 to January 2003)- Using information from the JAG Public Participation Plan, Phase II and III Environmental Site Assessments, the Technology Demonstration, and other successful cleanups, four cleanup options are developed and evaluated for the Tar Ponds and four for the Coke Ovens.Public Participation Plan (February 2003 to April 2003)- JAG receives community input on the four options developed for each of the two sites.Public Participation Plan (April 2003)- Using the community input and the technical reports, JAG makes a recommendation to government on acceptable cleanup options. |
| Regulatory Approvals Required: | Government Approval (April 2003 to Summer 2003)- Governments select a cleanup option based on the JAG recommendation, the technical reports, and other information. |
| Exceedance of Set Standards: | n/a |
|
Technologies Used: |
Technology Demonstration (March 2000 to October 2002) - Remediation industry conducts laboratory tests to treat Tar Ponds sediments. Seven different trains using eleven technologies tested.Technical experts will present the community and government with a final list of cleanup options. Those options will be selected based on technical knowledge and the preferences of the community. (on-going) |
|
Description: Phase II and III Investigation and Risk Assessment (March 2000 to October 2002) - Over 2,000 samples of water, groundwater, soil, sediment and biota collected during two sampling periods. Eight major reports with over 10,000 pages describing the types and locations of contaminants, and their impact, if any, on the environment and community.Environmental Assessment (Summer 2003 to Fall 2004)- The cleanup project is reviewed in a coordinated manner to meet federal and provincial environmental assessment requirements and to ensure that the selected option properly considers the effects of proposed projects on the bio-physical environment as well as on the social and economic environments of the people to be affected.Big Cleanup (Winter 2004/2005)- The Big Cleanup begins. |
