For metals criteria involving equations with hardness, the hardness shall be set as 25 mg/L if actual hardness is < 25mg/L and setat 400 mg/L if actual hardness is > 400 mg/L. The concentration causing impairment for nutrient listings is the median.3Priority and schedule for this WBID reflects the priority established for the WBID in the 1998 303(d) list.
