Section 38-104. Special Uses of Wastewater Sewers. <br /> <br /> Ail discharges of s%ormwater, surface water, groundwater, <br />roof runoff, subsurface drainage, or other waters not intended <br />to be treated in the treatment facility shall be made to storm <br />sewers, or natural outlets designed for such discharges. Any <br />connection, drain, or arrangement which will permit any such <br />waters to enter any other wastewater sewer shall be deemed <br />to be a violation of this Article. <br /> <br />Section 38-105. Restricted Discharges. <br /> <br /> (a) No person shall discharge or cause to be discharged <br />to any of the City's wastewater facilities any substances, <br />materials, waters, or wastes in such quantities or concen- <br />trations which will: <br /> <br /> (1) Create a fire or explosion hazard including, <br />but not Iimi%ed to, gasoline, benzene, naptha, fuel oil, or <br />other flarm~able or explosive liquid, solid, or gas; <br /> <br /> ~2) Cause corrosive damage or hazard to structures, <br />equipment, or personnel of the wastewater facilities, but in <br />no case discharges with the following property: <br /> <br />(i) Having a pH lower than 5.0 or greater than <br /> <br />9.0; <br /> <br /> (3~ Cause obstruction to the flow in sewers, or <br />other interference with the operation of wastewater facilities <br />due to accumulation of solid or viscous materials; <br /> <br /> ~4) Constitute a rate of discharge or substantial <br />deviation from normal rates of discharge ("slug discharge"), <br />sufficient to cause interference in the operation and per- <br />formance of the wastewater facilities; <br /> <br /> C5) Contain heat in a~ounts which will accelerate <br />the biodegradation of wastes, causing the formation of excessive <br />amounts of hydrogen sulfide in the wastewater sewer or inhibit <br />biological activity in the wastewater treatment facilities, <br />but in no case shall th~ discharge of heat cause the temperature <br />in the City wastewater sewer to exceed 58° C (150° F) or the <br />temperature of the infiuent to the treatment facilities to exceed <br />40° C (104° P) unless the facilities can accomodate such heat; <br /> <br /> (6) Contain more than 100 milligrams per liter of <br />nonbiodegradabte oils of mineral or petroleu~ origin; <br /> <br />fT) Contain floatable oils, fat, or grease; <br /> <br />8 <br /> <br /> <br />
