New Route Chosen for Coke Ovens Brook

first_imgAn engineering report on the Tar Ponds and Coke Ovens cleanuprecommends rerouting Coke Ovens Brook along two branches. Previous studies recommended moving the brook to an area where itwill not pick up contaminated groundwater as it passes throughthe Coke Ovens site. Moving the brook will also permit a morethorough cleanup of the stream bed, where contaminantsaccumulated during a century of coke production. The full report of the conceptual design by the engineering firmsDillon Consulting Ltd. and Franz Environmental Inc. is availableon the Sydney Tar Ponds Agency website at www.gov.ns.ca/STPA/reports/Coke_Ovens_Brook_Realignment_2004.pdf . The Sydney Tar Ponds Agency will commission a detailedengineering design of the realignment, and conduct anenvironmental screening. Work on the project will begin in thesummer of 2005. “This is an exciting development,” said Richard Morykot, theSydney Tar Ponds Agency engineer who supervised the project.”It’s the first concrete step in the big cleanup.” The newly realigned brook will have two branches. The south branch will start at the outflow from the MAID Pond,behind the Schwartz building on Vulcan Avenue. It will run alongthe southern boundary of the Coke Ovens site, parallel to VulcanAvenue, through an area known as Mullin’s Bank. Near the westernboundary of the site, the brook will merge with Cagney Brook andrun north, parallel to Victoria Road, and then follow theexisting channel under the Victoria Road overpass. The north branch will run along the Whitney Pier side of theSydney Coal Railway track and the SPAR road, picking up flowsfrom several smaller brooks along the way. It will cross underthe tracks and the Spar Road at a point just east of Lingan Road,and follow the rail spur through the Coke Ovens site to join thesouth branch at the Victoria Road overpass. Part of the relocated south branch will be piped underground, andportions of both branches will be lined with synthetic materialor clay to prevent recontamination. Engineering work continues on three other projects that have beenadvanced to prevent environmental damage while the cleanupundergoes mandatory environmental assessment. The projectsinclude the construction of a coffer dam at Battery Point, theclean up of the cooling pond at the southwest corner of the Syscoproperty, and the relocation of the Victoria Road water main. The report was funded under the 1999 federal-provincial-municipalcost share agreement for the Tar Ponds and Coke Ovens cleanup.last_img
