Unocal (Beaumont Terminal)
Peeling lead contaminated paint had to be removed and steel surfaces prepared for repainting. Simple sandblast operations had been done traditionaly. Those yielded large quantities of lead contaminated used blast sand that was D008 prior to Landfilling in a RCRA Subtitle C Facility
Multiple tanks required repainting. Several had lead paint of various lead concentrations up to 12% lead. The Wheelaborator Company used steel shot to remove over 80% of the lead paint surface. Treated sand blast (Blastox) was used on inacessible or difficult surface configurations and generated some limited quantities of used blast sand containing immovilized lead paint particles. The steel shot paint removal generated drummed lead paint chips and dust.
From multiple crude oil tank painting operations, five roll-off boxes of non-hazardous used blast sand was integrated into a recycle operation and became part of an asphalt paving product used for parking lot paving or highway maintenance. Eleven drums of paint chips and dust were shipped to CWM's Carlyss, La. facility to be stabilized and landfilled as allowed under RCRA subtitle C.
Details of Reductions
Additional Information :
The successful use of technology costs more in the cost of extended operations with several companies schedules having to be meshed together. This facet of the project is not assessed. Disposal costs appear to be reduced by approximately $500,000 compared to traditional methods. Blastox and Wheelabrator operations are now an institution.
