Neal Run Restoration Area

The Neal Run Restoration Project has undergone several phases.  Phase I involved the removal of 37, 608 tons of coal refuse and the installation of over 2500 feet of Oxidation Precipitation Channels (OPCs), also known as Terraced Iron Formations (TIFs).  This project was completed in 2012 and resulted in low-PH iron removal.  During the summer of 2018, an Auto-Flushing, Vertical Flow Pond (AFVFP) containing 715-tons of crushed limestone to generate alkalinity for metal removal and a 1/4-acre settling pond for the retention of metal precipitates was constructed.
