Lake Lee has a phosphorus total maximum daily load $($TMDL$)$ established at $656\mathrm{.}03k\frac{g}{y}r.$ The only known point source, a local wastewater treatment

plant, is permitted to discharge $0\mathrm{.}68lb\frac{m}{?}$ day of phosphorus into Lake Lee. The total phosphorus $($TP$)$ loading from the farmland within the Lake Lee

watershed is estimated at $253\mathrm{.}85k\frac{g}{y}r.$ The associated established margin of safety is $10\%.$ To meet Lake Lee's phosphorus TMDL$,$ the additional

allowable TP load allocation within the Lake Lee watershed is most nearly

A$.220k\frac{g}{y}r$

B$.260k\frac{g}{y}r$

C$.340k\frac{g}{y}r$

D$.480k\frac{g}{y}r$
