Abstract
Due to the existing and proposed regulations on chromium and in particular CCC emissions, AAPPSO tasked OCRC to investigate alternative environmentally acceptable pretreatments to ensure the Army's compliance. The results of the corrosion performance assessment identified that CCC could be eliminated from the RRAD process if enhanced quality assurance procedures were implemented. The elimination of CCC saved the Depot $200,000 in handling, treatment, and disposal costs (per year) as well as $3,000,000 in facility modernization. The alternative process of providing an adequate surface profile provided by redgarnet blast and enhanced quality controls has enabled RRAD to reduce their hazardous waste generation without compromising the quality of their product.
