(A)   Wastes discharged into the public sewers shall be subject to periodic inspection and a determination of character and concentration. The determinations shall be made as often as deemed necessary by the Secretary.
   (B)   When automatic flow measurement and sampling facilities are not available, the samples shall be collected by the city in such a manner to be representative of the composition of the wastes. The sampling may be accomplished either manually or by the use of mechanical equipment. Access to the sampling locations shall be granted to the secretary or his or her duly authorized representatives at all times.
   (C)   All measurements, tests, and analyses of the characteristics of waters and wastes to which reference is made in these rules and regulations shall be determined by the city in accordance with the latest edition of standard methods and shall be determined at a control manhole provided, or taken at said control manhole. In the event that no special manhole has been required, the control manhole shall be considered to be the nearest downstream manhole in the public sewer to the point at which the building sewer is connected. Sampling shall be carried out by the city 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.
