. . I Ordinance No. 1357 , Page 5. (b) The wastes will not impair the treatment process: (c) The discharger of the wastes enters into a con- tractual agreement with the City of La Porte provid- ing for a surcharge over and above the existing sewer rates, said contractual agreement to be incor- porated fully by reference into the terms of the annual permit contemplated in Sections 18 and 19, infra. The surcharge on industrial wastes is to be computed on the following basis: ISS = (BOD + ~ ) X (0 & M Cost) X (Vol): where 250 300 (l)ISS represents Industrial Waste Surcharge in Dollars: . (2)BOD represents the Biochemical Oxygen Demand (mg/l) of the Industrial Waste as determined under standard laboratory cond i tions for a period of 5 days at 200 C. Note: for concentrations less than or equal to 250 mg/l the value of BOD shall be considered 0: (3)SS represents Waste (mg/l). than or equal be considered Suspended Solids of the Industrial Note: For concentrations less to 300 mg/l the value of SS shall zero: (4)0 & M Cost represents Operations and Maintenance Cost of La Porte I s Wastewater Treatment Facil- ity(s). Note: The operations and maintenance cost as determined by the City of La Porte shall be periodically updated and defined by companion ordinances which concurrently establish water and sewer rates: I (5)vol represents Volume Discharged in Thousand Gallons. I The volume of wastes may be determined by the same methods used to calculate the regular sewer service charge. For establishments discharging less than 20,000 gallons per day, the BOD and suspended solids values may be determined from standard values for vari- ous industries established by the Approving Authority, and may also be incorporated as a condition into the terms of the annual permit contemplated in Sections 18 and 19, infra. The Approving Authority in said case may elect to follow the provisions of Section 14, supra. Provided, that in all cases in which the discharge from any establishment exceeds 20,000 gal- lons per day, the provisions of Sections 14 and 15, supra, shall be followed. Whenever samples of the discharges of any establishment are collected, pur- suant to the terms of said Sections 14 and l5, supra, the BOD and suspended solids values shall be determined by the Approving Authority, and a report of said samples shall be made. All sampling and testing contemplated herein shall be pursuant to the provisions of Section 15, supra, and a finding shall be made establishing whether such samples are in compliance
