Trim Blasting Continues on West Slope
 
CHATTANOOGA, Tenn. – Today, crews continued with trim blasting by setting off a series of trim blasts on the western side of the slide area to remove an unstable plane of rock on the slope face.  The blasts were set off removing 20’ by 20’ sections of the unstable slope as part of the overall remediation plan.  Crews also worked on the east side of the slope where they continued scaling operation to remove loose debris to make the work area below safe for drilling operations to take place.  A catchment pad of loose gravel was dumped on the roadway surface below the eastern side of the slope.  The blanket of gravel serves as an energy dissipater for falling boulders to lessen the possibility of the boulders striking TVA Dam #2 or the cable anchor bridge suspended above Dam #2.
 

Polk County US-64 Rockslide Update for December 10

CHATTANOOGA, Tenn. – Today, crews with Blalock & Sons and subcontractor Dyno Nobel set off a series of trim blasts on the western side of the slide area to remove an unstable plane of rock on the slope face.  Several small blasts were used to remove 20’ by 20’ sections of the unstable slope as part of the overall remediation plan.  On the eastern side of the rockslide, crews continued scaling the area to remove loose debris and make the area below safer for drilling.  A catchment pad of loose gravel was dumped on the roadway surface below the eastern side of the slope to help absorb energy from falling boulders.  The blanket of gravel lessens the possibility of boulders striking TVA Ocoee 2 Dam or the cable anchor bridge suspended above the dam.
 
The contractor plans to continue blasting on the west side of the slope tomorrow and is scheduled to begin hauling blast and slide debris from the site as soon as possible. This will allow the contractor to continue to progress eastward with drilling and trim blasting operations.  Debris removal work is expected to continue through the weekend.
