Bridge maintenance painting employs solvent-based coatings that generate volatile organic compounds (VOCs) that contribute to air-quality problems. Methods for capturing VOCs during normal Kentucky Transportation Cabinet (KYTC) maintenance painting operations were investigated. One method, activated carbon adsorption, is adaptable to KYTC operations. Related factors including area of bridge, coating systems, containment volumes and VOC out gassing rates were reviewed. A commercial source of activated carbon adsorption equipment was identified and issues related to employing that technology for bridge painting were identified.
