Since the 1980s, the U.S. Environmental Protection Agency (EPA) has collected industry-sector data on stormwater discharge. The linked presentation provides a comparison of these historic industrial stormwater results to the many of the ADEQ stormwater benchmark concentrations. The results are discussed in context of which stormwater benchmark parameters have a higher potential for exceedance of benchmark values. This presentation also discusses which of the industrial sectors have a higher potential for exceedance of their specific benchmark values.
Note: NDDH uses the same benchmark concentrations used by EPA and many other States; although the this linked presentation was specific to Minnesota, the analysis and conclusions apply to Norh Dakota.
