DOTMDL

The capacity of the DWSC to assimilate oxygen demand exerted by incoming loads of oxygen demanding substances is a function of the flow rate through the DWSC and of temperature. Based on equitability and other considerations, this TMDL apportions loading capacity (pounds of oxygen demand exerted in the DWSC per day), less a margin of safety in equal amounts to each of the three main contributing factors. To account for flow measurement error and technical uncertainty, a forty-percent margin of safety is imposed on the total loading capacity. Each of the three main contributing factors is also equally responsible for reducing the excess net oxygen demand exerted in the DWSC.
