PORT TOWNSEND — East Jefferson Fire Rescue and Port Ludlow Fire & Rescue firefighters extinguished a fire at the Port Townsend Paper Mill on Tuesday morning. The fire originated in a large concrete vault and no other damage was reported, Chief Bret Black said. The cause of the fire has not been determined due to access issues. “It was not safe to put anyone in the room. It was a confined space,” Black said. “We had to stage ourselves back a ways and spray inside the vault,” he explained. The building’s sprinklers were not activated, he said.
