Douglas Walker, 44, a maintenance worker on the grounds, was charged with second-degree reckless endangerment and third degree assault.
During an investigation, Orange and Rockland Utilities said that they believe some excavation work was performed on the grounds and that a gas pipe was bent and separated from a gas main resulting in an underground gas leak that seeped into the building through a “honeycomb” of drains.
South Nyack-Grand View Police Chief Brent Newbury said that the accident was unintentional but, “he should have been more responsible.”
Five Nyack College employees, two students and a South Nyack-Grand View Police Officer on patrol outside the building were injured during the blast.
