After meeting again with Resource Engineering and further discussions with Jerry Hodge, it is my opinion that the surcharge formula in its present form is not suitable for La Porte's current circumstances and recommend that it be altered to a simpler ratio-type formula. The formula currently in our ordinance is very similar to (and probably based on) a method suggested by the • E.P.A. The E.P.A. model formula and La Porte's current formula are re-written and re-arranged here fora simple comparison.* odel ormula Cs = Vol [Bc (BOD - 250) + Sc (SS - 300)] T t ~ ~ l .a Porte's :urrent • ,urcharge ISS = Vol [0.085 (BOD - 250) + 0.056 (SS - 300)] ormula As you can see each element of the two formulas correlate with the exception of the variables Bc and Sc. The E.P.A. formula defines Bc and Sc as: Bc = Operation & maintenance cost for treatment of a unit of BOD Sc = Operation & maintenance cost for treatment of a unit of TSS _ ~'~ `I
