Whenever an industrial plant or other establishment discharges or proposes to discharge industrial wastes into any waters, sewer, drain, watercourse or natural outlet in the City of Chicago and it becomes necessary either to:
(a) Reduce or modify the objectionable characteristics or constituents of such industrial wastes to meet the limits or requirements provided for in Section 11-4-1040 hereof and to prevent pollution; or
(b) Control the quantities and rates of discharge of such industrial wastes over a 24-hour day and a seven-day week to prevent surge discharges which may place an unreasonable burden upon the sewage works of the Metropolitan Water Reclamation District.
The commissioner shall require the owner, operator or tenant of such industrial plant, or other establishment, to provide adequate preliminary treatment or handling facilities to accomplish such a result. Before any permit for the construction of preliminary treatment or handling facilities shall be issued, plans, specifications and other pertinent data or information relating to such proposed treatment or handling facilities shall be submitted by the industry for the approval of the commissioner. No permit shall be issued and no construction of such facilities shall be commenced without the prior written approval of the commissioner; and no substantial alteration or addition to or in the sewer or drain or in the preliminary treatment or handling facilities shall be made without the prior written approval of the commissioner.
