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.
4 of the permits in subbasin 04040001 carry a numeric limit on Nickel, sludge, total, dry weight [as Ni], and 0 of those have a recorded exceedance. Nationwide the same parameter appears in 2,556 permits. A permit carrying several parameters is counted under each of them, so the parameter counts for one subbasin add up to more permits than it holds. The other parameters named in this subbasin are listed below.
