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, such plant or establishment shall either:
1. Reduce or modify the objectionable characteristics or constituents of such industrial wastes to meet the limits or requirements of Section 18-29-805.2 and to prevent pollution; or
2. 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 on the metropolitan water reclamation district.
The commissioner of water management shall require the owner, operator or tenant of such industrial plant or 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 is issued, plans, specifications and other pertinent data or information relating to such proposed treatment or handling facilities shall be submitted for the approval of said commissioner. No permit shall be issued and no construction of such facilities shall be commenced without the prior written approval of said 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 said commissioner.
