Hundreds of firefighters have been battling a trash fire inside Montgomery County’s incinerator plant since Thursday, and the smoldering blaze in a giant storage pit will continue to emit smoke and disrupt some nonresidential waste deliveries for days, fire officials said Sunday.

County Fire and Rescue Service units met an 85-foot tower of trash ablaze at about 6:30 p.m. Thursday inside the Montgomery County Resource Recovery Facility, about two miles southwest of Dickerson, fire department spokesman Pete Piringer said in a recorded statement Sunday.
