CPWG TOUR OF WASTEBEDS 1-8, May 24, 2011

NOTES by Cara Burton of the CPWG

The tour was conducted by the DEC’s Bob Edwards and lasted about one and one half hour. The walking tour went along the access road at the west end of the fair parking lot to the Point and back. David Coburn, from Onondaga County Parks, was also present.

History of WB1-8:
• Created early 1900’s by Solvay Process
• 350 acres
• 26 million cubic yards
• Part of 690 is on the wastebeds
• Closed when dike broke in 1940’s; dike broke as no “engineered berms”.
• Because the beds are unsubstantially fortified, this affects current possible uses for the sites.
• The new wastebeds created in Camillus have engineered berms.

Environmental problem with wastebeds is the base of the beds have groundwater issues, b-zene compounds and phenols; before Semet tar beds were created. Slurry was pumped up and then dried. The resulting waste compressed and now the base is 10 feet below lake level.

Around 1954, some of the property was deeded to New York State (the Fair parking area) and Onondaga County (shoreline). The shoreline is designated permanent parkland.
The group then started the walk to cliffline.
Shoreline “cove”/beach will have wetlands created:
• The “seeps”, white streams on flat area by shoreline have concentrated ‘zenes.
• Now is not good habitat, demonstrated by only grass having grown since 1940’s.
• Will have groundwater barriers again, but this will not be walls. Will be a trench with recovery wells. Trench give opportunity for run-off from both sides of trench---waterside & Cliffside---so water doesn’t run off into lake.
• Will revitalize this area to make up for the loss at Willis Ave. beds.
> 2.5 acre wetland to connect areas
> 7 acres other adjacent wetlands
> Flatlands will be dredged (taken to WB13) & new soil imported.
• The wetlands not connected to other remediated areas will be on the “highlands”. This will minimize rainwater coming down from the ridge area. Will use rainwater to make the wetlands, a.k.a. phytoremediation. A barrier will keep the rainwater from sinking into earth.

• The white cliffs will be stabilized.
• Gravel will stabilize along the shoreline; an issue is wave energy.
• The lake trail will go along the ridge.
• Question as to whether will have “hemi-marsh” (see: Waterfowlhabitat.pdf)
