Abstract:
Site‐specific acute and chronic toxicity tests with un‐ionized ammonia were conducted in Tittabawassee River water from Midland, Michigan. The results of these tests were used by the State of Michigan Department of Natural Resources (MDNR) to establish site‐specific acute and chronic un‐ionized ammonia water quality criteria for the portion of the river at Midland. The acute water‐quality criterion established by the state using walleye data from this study was 1.0 mg/L un‐ionized ammonia nitrogen. The chronic criterion established using fathead minnow embryo‐larval data was 0.095 mg/L un‐ionized ammonia nitrogen. The chronic criterion was used in determining the assimilative capacity for ammonia in this portion of the river. The MDNR allocated a portion of the assimilative capacity to each discharger and set effluent limitations based on the allocated capacities. Ammonia effluent limits have been set in the National Pollutant Discharge Elimination System (NPDES) permits of the Dow Chemical Company and the City of Midland. Ammonia effluent limits will be set in the NPDES permit of the Consumers Power Company.
