No person, firm or corporation shall discharge, or cause to be discharge, any stormwater, groundwater, roof runoff, or subsurface drainage to the POTW except as authorized by a wastewater contribution permit issued by the city in accordance with divisions 3 and 4 of this article.

(b)

Stormwater, other than that exempted under [subsection] (a) of this section, and all other unpolluted drainage, shall be discharged only to such sewers as are specifically designated as storm sewers or to a natural outlet approved by the city and other regulatory agencies, if different from the city. Unpolluted industrial cooling water or unpolluted process waters may be discharged to storm sewers or to natural outlets only after written approval of the city manager and the appropriate approval authority, if different from the city.

(c)

Except as otherwise provided herein, no waters or wastes may be discharged to the POTW or any sewer of any type or designation having:

(1)

A five-day BOD greater than three hundred (300) mg/l or one thousand two hundred (1,200) pounds per twenty-four-hour period;

(2)

Containing more than three hundred fifty (350) mg/l or five hundred (500) pounds per twenty-four-hour period of suspended solids (TSS);

(3)

Having an average daily flow greater than two (2) percent of the average daily water consumption of the city.

Such flows shall be subject to the review and permit processes of the city. Where necessary, in the opinion of the city, the owner shall provide, at his expense, such pretreatment as may be necessary to limit pollutants such as BOD and TSS as required in the industrial waste permit of the user, and control the quantities and rates of discharge of such wastes. Plans, specifications and any other pertinent information relating to the proposed pretreatment facilities shall be submitted for the approval of the city, and no construction of such facilities shall be commenced until the approvals are obtained in writing.
