(A) The admission into the public sewers of any waters or wastes having:
(1) A 5-day Biochemical Oxygen Demand greater than 300 parts per million by weight, or
(2) Containing any quantity of substances having the characteristics described in § 50.087, or
(3) having an average daily flow greater than 2% of the average daily sewage flow of the City shall be subject to the review and approval of the Inspector. Where necessary in the opinion of the Inspector, the owner shall provide, at his expense, such preliminary treatment as may be necessary to, (a) reduce the Biochemical Oxygen demand to 300 parts per million and the suspended solids to 350 parts per million and the suspended solids to 350 parts per million by weight, or (b) reduce objectionable characteristics or constituents to within the maximum limits, provided for in § 50.087 or, (c) control the quantities and rates of discharge of such waters or wastes.
(B) (1) Plans, specifications, and any other pertinent information relating to proposed preliminary treatment facilities shall be submitted for the approval of the Inspector and of the Sanitary Water Board of the State of Illinois, and no construction of such facilities shall be commenced until said approvals are obtained in writing. Where preliminary treatment facilities are provided for any waters or wastes, they shall be maintained continuously in satisfactory and effective operation by the owner at his expense.
(2) When required by the Inspector, the owner of any property that is served by a building sewer carrying industrial wastes shall install a suitable control manhole in the building sewer to facilitate observation, sampling and measurement of the wastes. Such manhole, when required, shall be accessibly approved by the Inspector. The manhole shall be installed by the owner at his expense and shall be maintained by him so as to be safe and accessible at all times.
(3) All measurements, tests, and analysis of the characteristics of waters and wastes to which reference is made herein shall be determined in accordance with “Standard Methods for the Examination of Water and Sewage” and shall be determined at the control manhole provided for herein or upon suitable samples 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.
(C) (1) Testing procedures provided herein shall, be consistent with the October 16, 1973, “Federal Register” 40 C.F.R. Part 136 entitled “Guidelines Establishing Test Procedures for Analysis of Pollutants”, any Federal Regulations regarding Pretreatment, and any other appropriate Federal Regulations.
(2) No statement contained in this Section shall be construed as preventing any special agreement or arrangement between the City and any industrial concern whereby any industrial waste of unusual strength or character may be accepted by the City for treatment, subject to payment therefor by the industrial concern.
