If a river with a seasonal low flow of 200cfs has a water quality standard for phosphorus of 0.02mg/l at total-P, find out the TMDL for P. Dispersed agricultural runoff contributes about 10lbs of P/day. If the MOS is set at 4lbs of P/day, what would be the maximum WLA of P from a pulp and paper mill’s WWTP discharging to the river? Ignore all other point and nonpoint sources?
