The Coast Guard has cleaned up the explosives, and the port was back to normal operations Friday.
"The incident response for the entire event was safe and was brought to a successful conclusion," said Port State Facility Lt. Robert Jones, facility security officer. "As a party in interest, the State Port Facility, shall have a direct interest in the investigation of the incident."
The spill caused no reported injuries or environmental damage.
