Sampling of the effluent of waste discharges may be accomplished manually or by the use of mechanical equipment to obtain a 24-hour composite sample which would be representative of the total effluent. Samples shall be taken at such intervals as determined by the approving authority as necessary to maintain a control over the discharges from the establishment. The methods used in the examination of all wastewater to determine suspended solids, BOD and concentrations of prohibited wastes shall be as set forth in § 50.16 of this chapter. All costs for sampling and testing of industrial discharges, as ordered by the approving authority, shall be paid by the person making such discharges. All tests shall be conducted by qualified personnel and in accordance with Standard Methods. Test results shall be reported within a reasonable time.
