The trustee has also announced that the two looming Asarco stacks will be knocked down on April 13, 2013, after sunrise. Both the 828' and 612' chimney columns will come down at the same time in an event involving pushing the stacks onto their sides like falling trees. Explosives will create a hole on one side of the base of each stack, like an ax creating a hole on one side of a tree, helping direct the columns into planned fall zones. Earthen berms and elevated mist systems will help reduce the spread of potentially harmful dust.
Interstate 10, which runs along the eastern edge of the primary site, will be closed 15 minutes before the blast and tentatively reopen as soon as 15 minutes afterward. Paisano Drive on the western edge will be closed to traffic three hours prior to demolition and could reopen one hour after the stacks fall. There will be no public viewing areas for the event, but local broadcasters are expected to carry it live on television.
