C. Major Commercial and Industrial Users are those having (1) a sewage discharge of at least 25,000 gallons per day, or having a daily discharge which is (2) intermittent or irregular in strength, amount or nature. Major Commercial and Industrial Users shall have monthly sewer charges, which may consist of all of the following charges:

Annual Capital Cost Recovery

Volume	$475,740 per million gallons per day of flow capacity
BOD	$37,868 per 1,000 lbs. per day of B.O.D. removal capacity2
SS	$37,390 per 1,000 lbs. per day of S.S. removal capacity3
NH3	$183,650 per 1,000 lbs. per day of NH3 removal capacity4

Operating and Maintenance Cost Recovery

Volume	$1,450.94 per million gallons
BOD	$247.75 per 1,000 lbs.2
SS	$411.75 per 1,000 lbs.3
NH3	$3,362.58 per 1,000 lbs.4

D. All classes of user shall be charged $4.45 per year for infiltration/inflow, which is already included in the rates shown under Tables A and B.

The volume of sewage shall be based upon a fixed percentage of water usage as noted, or based on standard methods acceptable to the Director.

The City may require the installation of special metering and sampling devices whenever the Director deems that such devices are required to determine the volume and/or strength of the sewage. A customer may also request the installation of a special metering device. Whenever special metering devices are installed, they shall be devices approved by the Director, and the cost of furnishing and installing said devices shall be borne by the customer.
____________________________________________________________________________ 

¹ HCF is the volume of sewage measured in hundred cubic feet, equal to 748 gallons. 

² BOD, Biochemical Oxygen Demand, is the quantity of oxygen utilized in the biological oxidation of organic matter under standard laboratory conditions for 5 days at a temperature of 20 degrees Centigrade. The determination of the charge for BOD is as follows: BOD in parts per million x 8.34 x volume in million gallons = pounds of BOD. 


³ SS, Suspended Solids, is that which either floats on the surface or is in suspension in sewage and which is determined by laboratory filtering. The determination of the charge for Suspended Solids is as follows: SS in parts per million x 8.34 x volume in million gallons = pounds of Suspended Solids. 


⁴ NH3, Ammonia, is that form of nitrogen in the tri-negative oxidation state, which is chemically definable as the compound NH3. The determination of the charge for Ammonia is as follows: NH3 in parts per million x 8.34 x volume in million gallons = pounds of Ammonia.
