§ 28-02-240. Compliance with standards—Industrial wastes.

All measurements, tests and analyses of the characteristics of waters and wastes shall be determined in accordance with the latest edition of "Standard Methods for the Examination of Water and Wastewater," published jointly by the American Public Health Association and American Water Works Association and the Water Pollution Control Federation, and shall be determined at the control manhole provided, or upon suitable samples taken at such control manhole. The control manhole provided shall be located so that sampling of the industrial waste will be performed before discharge into the public sewer system. Sampling shall be carried out by customarily accepted methods to reflect the effect of constituents upon the wastewater treatment works and to determine the existence of hazards to life, limb and property. (The particular analyses involved will determine whether a twenty-four-hour composite of all outfalls of a premise is appropriate or whether a grab sample or samples should be taken. Normally, but not always, COD, BOD and settleable solids analyses are obtained from twenty-four-hour composites of all outfalls whereas pH's are determined from periodic grab samples.)
