i <br />I <br />s' <br />i <br />(b) Which discharge wastewaters into <br />I <br />the system having an average concentration <br />in excess of 270 B.O.D. or 270 S.S.; <br />�i <br />shall pay, in addition to the ordinary user charge imposed by <br />i!! Batesville Ordinance No. 892 of 1978 as amended, a surcharge <br />which shall be computed as follows: <br />Monthly surcharge = A x 8.34 [B (SS -270) <br />+ C (BOD - 270)] Where: <br />A = millions of gallons of wastewater <br />discharged per month. <br />S.S. = suspended solids content <br />i' <br />II expressed in milligrams /liter. <br />,i <br />B.O.D. = biochemical oxygen demand <br />i <br />�! expressed in milligrams/liter. <br />B = cost per pound for treatment of <br />suspended soli -ds. <br />u <br />ii C = cost per pound for treatment of <br />i <br />concentrations having B.O.D. <br />2. That from the date of passage of this ordinance <br />i, to November 1, 1981, the average cost per pound for treatment <br />I of suspended solids (i.e. "B" in the above formula) shall be <br />i' $0.02 per pound; and the average cost per pound for treatment <br />of concentrations having biochemical oxygen demand (i.e. "C" in <br />the above formula) shall be $0.11 per pound. On and after <br />November 1, 1981, and annually thereafter, the values for factors) <br />B and C shall be determined as follows: <br />i <br />B = Suspended Solids = 1.0% (total 0 & M costs)_ <br />Cost Per Pound total pounds of S.S. treated in preceding <br />FY <br />C = B.O.D. Cost = 60% (total 0 & M costs) <br />Per Pound total pounds of B.O.D. in preceding FY <br />3. Each user falling into the category set out in <br />paragraph 1 above shall provide to and maintain for the use of <br />the Batesville Utilities Commission or its designee a suitable <br />accessible inspection chamber or manhole on the user's premises <br />- 2 - <br />
