Hanson Aggregates Pennsylvania has applied to the state Department of Environmental Protection Moshannon District Mining Office in Philipsburg to revise its permits to extend its Oak Hall Quarry, quarry PA depth by 200 feet, reports State College.
The application includes a request to increase the depth of mining at the quarry 200 feet below the existing approved pit floor elevation. The proposed permit area involves 315 acres. The current permit area is 331 acres.
A spokesman for Lehigh Hanson, the Irving, Texas-based U.S. parent company of the quarry operator, said the company has done “extensive hydrologic testing” which focused on ensuring “there would not be depletion or adverse impacts on Spring Creek.”
“There is not going to be any additional impact beyond what we’re doing now,” said Jeff Sieg, director of corporate communications for Lehigh Hanson.
But some local residents are petitioning for a public hearing on an application concerned about blasting at the limestone quarry.
