A. Stormwater And Surface Water Runoff:
1. No person shall discharge, or cause to be discharged, any stormwater, surface water, groundwater, roof runoff, subsurface drainage, uncontaminated cooling water, or unpolluted industrial process waters to any sanitary sewer.
2. Stormwater and all other unpolluted drainage shall be discharged to such sewers as are specifically designated as storm sewers, or to a natural outlet approved by the village. Industrial cooling water or unpolluted process waters may be discharged, on approval of the village, to a storm sewer or natural outlet.
B. Prohibited Discharges:
1. No user shall contribute or cause to be contributed, directly or indirectly, any pollutant or wastewater which will interfere with the operation or performance of the publicly owned treatment works (POTW) or will pass through the POTW.
2. No user shall contribute or cause to be discharged, directly or indirectly, any of the following described substances into a village sewer or otherwise to the facilities of the SMSD:
a. Any liquids, solids or gases which, by reason of their nature or quantity, are, or may be, sufficient, either alone or by interaction, to cause fire or explosion or be injurious in any other way to the operation of the POTW.
b. Solids or viscous substances, including fats, oil or grease, which will or may cause obstruction to the flow in a sewer or other interference with the operation of the POTW.
c. Any wastewater having a pH less than 5.0 or an extreme base condition or having any other corrosive property capable of causing damage or hazard to structures, equipment, or personnel of the system.
d. Any wastewater containing toxic pollutants in sufficient quantity, either singly or by interaction, to injure or interfere with any wastewater treatment process, constitute a hazard to humans or animals, or exceed the limitation set forth in national categorical pretreatment standards promulgated by the USEPA in accordance with section 307(b) and (c) of the act.
e. Any noxious or malodorous liquids, gases, or solids which, either singly or by interaction, are capable of creating a public nuisance or hazard to life or are sufficient to prevent entry into the district sewers for their maintenance and repair.
f. Any substance which may cause the SMSD effluent or treatment residues, sludges, or scums to be unsuitable for reclamation and reuse or to interfere with the reclamation process. In no case shall a substance discharged to the SMSD cause the SMSD to be in noncompliance with sludge use or disposal criteria; the SMSD IEPA sludge disposal operating permit, guidelines or regulations developed under section 405 of the act; or any criteria, guidelines, or regulations affecting sludge use or disposal developed pursuant to the solid waste disposal act, the clean air act, the toxic substances control act, or state standards applicable to the sludge management method being used.
g. Any substance which will cause the SMSD to violate its NPDES permit and/or other IEPA sludge disposal operating permits.
h. Any substance with objectionable color not removed in the treatment process, such as, but not limited to, dye wastes and vegetable tanning solutions.
i. Any wastewater having a temperature at the point of discharge to the POTW which will inhibit biological activity in the POTW treatment plant resulting in interference. In no case shall wastewater be introduced to the district facilities which exceeds sixty five degrees centigrade (65°C) (140°F) at the SMSD treatment plant.
j. Any slug load.
k. Any wastewater containing any radioactive wastes or isotopes of such half life or concentration as exceeds limits established by the SMSD in compliance with applicable state or federal regulations.
l. Any wastewater which causes a hazard to human life or creates a public nuisance.
C. Industrial Discharges: Industrial users must comply with all applicable ordinances of the SMSD. In addition, industrial wastes must be handled in a manner which will create no local hazards or nuisances for workers or village inhabitants. (1984 Code § 7-4-4)
