Removal of Asbestos-Containing Coatings (ACC) from gas transmission pipelines. Final report, January 1991-October 1993
Corrosion control coatings on transmission pipelines may contain asbestos as a secondary component of the coating. Current environmental and health regulations require a wet removal process for asbestos materials that provides close control of airborne emissions and asbestos fibers in effluent water. Modification of current line-traveling, water jet equipment was successfully completed in developing an economic removal process for asbestos-containing coatings (ACC). Materials handling components were added in yard experiments that permitted water jet removal, slurry filtration, and residue containerization meeting emission control levels, while providing pipe cleanliness suitable for recoating. Field evaluations under in-the-ditch and over-the-ditch conditions on 16-, 26- and 30-inch pipelines verified the achievement of design coating removal rates and asbestos emission control that meets current regulations.
