a key practice required to control petcoke fugitive emissions. There are three primary techniques that should be considered to maintain optimal moisture content and control potential petcoke emissions (i.e. fugitive dust) during storage: 1) pile maintenance, 2) wetting with water, and 3) treating with an anti-dust chemical agent. 6.2 Pile ...Web
