Following crew mobilization, Health and Safety orientation, and installation of environmental controls, VIASANT crews initiated wet dust suppression measures to mitigate cross contamination of the adjacent ship channel and industrial properties during decommissioning activities. Site demolition activities included mechanical razing of the rotary hearth, air intake furnace, hot and cold plenum, 135 foot exhaust stack, 60 foot tall hopper elevator and four baghouses.
All refractory brick, brick fines and chrome waste residuals removed during demolition of the furnace and rotary hearth were immediately contained for placement within lined 20 cubic yard roll-off boxes. More than 100 loads of Cr+6 hazardous brick and residuals were properly contained and shipped off site for encapsulation at a licensed hazardous waste disposal facility.
All demolition steel was staged at a designated zone, neutralized and wet decontaminated prior to shipment off site as scrap. Approximately 1,800 tons of cleaned demolition steel was sized and shipped off site for recycling.
All project decontamination rinsate and dust suppression water was collected, filtered and transferred to the site waste water treatment facility for proper handling prior to discharge. With the exception of universal waste and chrome contaminated refractory brick and residuals, 100% of the razed structures were recycled.
Following demolition activities, waste management and recycling, VIASANT crews neutralized and wet decontaminated the vacant concrete pad and surrounding areas leaving the site in a stable, environmentally clean condition available for reuse by the client. |
