A. Periodic measurements of flow rates, flow volumes, COD and suspended solids for use in determining the annual industrial wastewater treatment charge, and such measurements of other constituents believed necessary by the district engineer, shall be made by all industrial wastewater dischargers, unless specifically relieved in writing of such obligation by the district engineer.
B. All wastewater analyses shall be conducted in accordance with the appropriate procedure contained in "standard methods."
