For each billing period where applicable, the extra loading surcharge (“ELS”) provided by Chapter 923 and Section 923.046 shall be charged and billed directly to each respective industrial user liable for such charge by the Director. Where extra loadings are substantially uniform over the billing period in question in the opinion of the Service Director, the Director may charge and bill the ELS using an extra loading surcharge rate (“ELSR”) which shall be equal to the ordinary household waste (OW) volume rate or sewer rental fee applicable to the industrial user for operation, maintenance, and replacement (“R”) during the period in question multiplied by the sum of fractions by which the loadings exceed the OW loadings multiplied by the budget fraction factors attributable to each of such loadings, to wit: 30.1% for SS; 58.5% for BOD; 4.1% for P; and 0.4% for O&G. The Service Director may also arrange to have such charge included and combined with OW billings if the excess loadings are substantially uniform and recurring in the opinion of the Director. Provided further, however, that the Director shall periodically audit all ELS billings and then charge and bill the respective user an ELS adjustment charge equivalent to the amount by which the ELS computed on a cost per pound basis exceeds the ELS collected using the ELSR billing method, if any.
