CDPS002 Upgradicnt of all possible point and nonpoint flows from the Mine. BB -A Discharge from pipe fed from Mine. 1313-13 Discharge from settling pond below Mine that captures all Mine point source releases. BB -C Location below BB -B, BB -A, CDPS001 and CDPS002 that may also collect any nonpoint contribution. BB -D Location below all other sampling sites, located immediately adjacent to access road.
