Blasting to begin at State High project site

R.C. Bowman, a Mill Hall-based contractor, will begin subsurface rock blasting this week to loosen solid bedrock for excavation at the State High project site.

Five to six detonations will be done through mid-July, depending on site conditions, according to a press release from State College Area School District.

The construction team will clear a 300-foot radius around the blast zone for safety purposes. About one minute before detonations an air horn will sound three times, followed by the blast and an all-clear horn.

Blasting will be controlled through the use of protective blasting mats and existing top soil to prevent material from becoming airborne, though minor ground vibrations or sound may be heard by those near the site. Blasts will occur during normal working hours and be limited to no more than once a day.

Philipsburg-based Douglas Explosives will conduct the blasting.
