(A) Major industrial users shall provide a sampling station which shall be monitored as required to calculate appropriate user charges. Charges to major industrial users shall be established on the basis of metered flow and tested strength of wastewater discharges.
(B) Monthly flow units shall be calculated from readings from individual industry owned flow meters. Monthly loadings of BOD, SS and oil and grease are calculated from laboratory analysis of individual composited wastewater samples applied to flows during the sampling period. Individual industry charges shall be based upon actual usage. Discharges over a weekend shall be measured with the next analysis and charged for actual sewage discharged at the rates established herein. Grease loadings in excess of 100 milligrams per liter are billed for the same rate as for solids except as modified by surcharges.
