(d) INTENDED USE

This material will be used in the chemical process as a "detackifier" for the ink sludge in the Bureau's Wastewater Pretreatment Plant. Without the "detackifier" added prior to the sulfuric acid, the sludge will precipitate to the bottom of the tank and form a tar like material, which is non-pumpable through the system.
