ReceivedDec 17, 2025
Maryland Department of the Environment issued a Notice of Violation to Reworld Montgomery, Inc. after a September 2025 stack test found Unit 3 of the Resource Recovery Facility emitting dioxins and furans at 54.8 ng/dscm—nearly double the permitted 30 ng/dscm limit. A significant tear in the unit's baghouse filter was identified as a contributing cause; Reworld shut down the unit, completed repairs, and conducted an engineering retest on Dec. 1, 2025, which showed emissions within allowable limits. Montgomery County DEP was notified Nov. 14 and says it will engage third-party professionals to evaluate possible health risks.
