A subbasin is a unit of the national Watershed Boundary Dataset, and water crosses state lines: a permit is placed here by the outfall EPA names as its representative discharge point.
12 of the permits in subbasin 04040001 carry a numeric limit on Cyanide, total [as CN], and 6 of those have a recorded exceedance. Nationwide the same parameter appears in 2,531 permits.
