"Environmental groups have appealed a ruling by a federal commission that last month granted Maryland’s Conowingo Dam a new 50-year license.
The groups are concerned that the license missed an opportunity to address several environmental problems caused by the hydroelectric dam, but they also contend that the Federal Energy Regulatory Commission ran afoul of certain legal duties in issuing it.
At one time, the dam, which spans the Susquehanna River, a Chesapeake Bay tributary that flows between Harford and Cecil counties, trapped a significant amount of sediment and pollutants that would have flowed downstream. But now it’s full, and when big storms come, the trapped debris and nutrients rush down the river and into the bay, burying underwater vegetation and contributing to damaging algae blooms."
