While the differences between Wisconsin allowance of concentration of chronic and acute copper and nickel, and chronic endrin and selenium are slight and in some cases Wisconsin's proposed equations for concentration of metals in water is stricter than that of the EPA, it should be noted that the formula for the concentration for Chronic Nickel Criteria for cold water, warm water sportfish, warm water forage fish, and limited forage fish is more lax than that set out by the EPA. While this is merely a note and not a demand for action, the EPA would do well to remember that giving any amount of autonomy to a state in terms of environmental protocol opens the gate for more autonomy. In the future it might be best if all rules adopted by states were as strict as or stricter than the national rules.
