LUZERNE — One week after a mine subsidence opened in Toby’s Creek behind Luzerne Lumber, the state Department of Environmental Protection (DEP) issued another update on the efforts to fill in the hole and stabilize the creek bed.
DEP spokesperson Colleen Connolly stated that a cofferdam was placed on the creek over the weekend to stop the water flow to the subsidence.
On Sunday, an additional 80 cubic yards of concrete was injected into the subsidence, increasing the total concrete used to about 280 cubic yards, according to Connolly.
The concrete was covered with clay and rocks, and the flow in Toby Creek has noticeably increased.
Connolly mentioned that the DEP anticipates some settling of the installed material and will continue to monitor over the next few days.
