§ 51.072 MEASUREMENTS; TESTS; ANALYSES.
   (A)   General provisions.
      (1)   All measurements, tests, and analyses of the characteristics of waters and wastes to which reference is made in this chapter shall be determined in accordance with the latest edition of “Standard Methods for the Examination of Water and Waste Water,” published by the American Public Health Association, or methods approved by the state environmental protection agency or Manual of Laboratory Methods for Sewage Plants published by the state department of public health. Substances shall be determined at the control manhole provided, or upon suitable samples taken at the control manhole. Sampling shall be carried out by customarily accepted methods to reflect the effect of constituents upon the sewage works and to determine the existence of hazards to life, limb, and property.
      (2)   The particular analyses involved will determine whether a 24-hour composite of all outfalls of a premise is appropriate or whether a grab sample or samples should be taken. Normally, but not always, BOD and suspended solids analyses are obtained from 24-hour composites of all outfalls whereas pH's are determined from periodic grab samples.
   (B)   Any person discharging wastes having concentrations greater than the normal concentrations as set forth herein shall upon notification by the approving authority install a composite sampler with a compatible pacing (metering) device for monitoring the substances. The pacing and sampling devices shall be of a type approved by the Operator. All testing and measuring procedures for the analysis of pollutants shall be in conformance with 40 CFR Part 136.
   (C)   The cost of all required measurements, tests, and analyses shall be borne by the contributor.
   (D)   No statement contained in §§ 51.065 to 51.075, inclusive, shall be construed as presenting any special agreement or arrangement between the city and any industrial concern whereby an industrial waste of unusual strength or character may be accepted by the city for treatment, subject to payment therefore, in accordance with the provisions of this chapter, by the industrial concern, provided the payments are in accordance with federal and state guidelines for user charge system and industrial cost recovery system.
