Buried 500-pound bombs found at Ravenna Arsenal

When a white phosphorus rifle grenade detonated at a disposal area within the former Ravenna Arsenal in 2007, it was the tip-off to a new potentially explosive problem.


Now, evidence of at least three 500-pound general purpose bombs and a 105 mm projectile have been found in the area, known as Rocket Ridge.


On Wednesday, the Restoration Advisory Board of the former Army ammunition plant east of Ravenna learned of plans to survey the 80- by 90-foot area to determine the type and number of suspect munitions, and how to deal with them.


Brian Stockwell of PIKA International said it is not known if the munitions are dangerous, or if there are more in the site adjacent to Sand Creek.


Rocket Ridge is a hillside within an open demolition area used in the 1940s and ’50s to burn out or detonate defective and off-specification munitions made at the arsenal. The “demilitarized” munitions were then dumped over the hillside.


Stockwell said the area looks “like an upside down hippopotamus” and may be four or five feet deep. He said it is “highly possible” more bombs will be discovered in the pile.


The arsenal made about 60,000 aerial bombs during World War II, sized from 100 to 2,000 pounds, said Mark Patterson, U.S. Army co-chairman of the RAB.


Plans are to determine if the 500-pound bombs are fuzed. If not, they can be removed, Stockwell said.


“The consensus is they probably aren’t,” he said.


If they are, it would have to be determined how best to deal with them.


An exploding 500-pound bomb, with about 200 pounds of high explosive, has a fragmentation radius of about 2,500 feet, Stockwell said, still well within the arsenal boundary.


Rocket Ridge was discovered in 2004. Before the corroded white phosphorus grenade self-ignited in 2007, it was believed the site contained no dangerous munitions, Patterson said. There were no injuries in that incident.


Plans are to deal with the known bombs and projectile and then survey the area later this year and determine what else is on the site. A contract to clean up the site next year would follow.


Before the three weeks of field work and investigation can begin, Stockwell said it will take about a week to build an access road to the site and a week to remove vegetation.


In other business, the RAB was updated on asbestos and munition debris clean up work at the Winklepeck Burning Ground which has now been turned into a firing range by the Ohio Army National Guard.


About 7,300 cubic yards of soil and about 10 tons of metal debris were removed.
