Rick Van Unen wants to clear the air.The owner of Van Unen Miersma Propane, the site of Wednesday’s four-hour standoff between police and a gunman, believes the stories of an exploding tank have been grossly exaggerated.There was fire, to be sure, but no tank exploded.“Get hit by a propane truck, now there’s a story,” Van Unen said on Friday.The propane yard at the southwest corner of the Austin Road and Highway 99 interchange became the backdrop for a lengthy standoff that resulted in freeway and railroad closures, reports of gun fire and eventually the arrest of Manteca resident Jason Stowers, 32.The drama, as it was played out on television and the Internet, was spiked by the involvement of an industrial-sized propane tank and transport truck.“You could see it all over Facebook,” Van Unen said. “You’ve got people in Modesto wondering if their families are going to be OK.”Van Unen confirms there was a fire when Stowers crashed into a re-sale tank on the property. That particular tank is used to fill smaller propane tanks for barbecues and such.The tank was knocked off its cement base and turned over, disconnecting a hose and vapor line.
