No discharger shall contribute or cause to be discharged, directly or indirectly, any of the following described substances into the wastewater disposal system or otherwise to the facilities of the City:
(a) Any liquids, solids or gases which by reason of their nature or quantity are, or may be, sufficient either alone or by interaction with other substances that exhibit characteristics of explosivity. At no time shall two successive readings on a meter capable of reading L.E.L (lower explosive limit) at a point at the nearest accessible point to the POTW in a sanitary sewer, at the point of discharge into the POTW, or at any point in the POTW be more than five percent (5%) nor any single reading greater than ten percent (10%).
(b) Solids or viscous substances such as, but not limited to, straw, metal fragments, glass, rags, plastics, garbage that has not been properly shredded and other wastes which obstruct the flow in a sewer or the risk thereof or cause interference to the operation of the POTW or the risk thereto.
(c) Any wastewater having pH less than 5.0 or higher than 11.0 or having a corrosive property that causes damage or hazard to structures, equipment or personnel of the system or the risk thereto.
(d) Any wastewater containing toxic pollutants that either singly or by interaction cause damage or interference with any wastewater treatment process or the risk thereto, or constitute a hazard to humans or animals or a risk thereto, or exceed the limits established by the City in compliance with applicable State and Federal regulations.
(e) Any noxious or malodorous liquid, gas or solid that either singly or by interaction creates damage or prejudice to others or the public or hazard to life or the risk thereof or is sufficient to prevent entry into the sewers for their maintenance and repair.
(f) Any substance which shall cause the POTW's effluent or treatment residues, sludges or scums to interfere with the City's goals for reclamation and reuse or to be unsuitable for reclamation and reuse or to interfere with the reclamation process.
(g) Any substance which will cause the POTW to violate it NPDES and/or other disposal system permits or the risk thereof.
(h) Any substance with such color not removed in the treatment process, such as but limited to dye wastes and vegetable tanning solutions, which place the City of Mansfield in violation of its NPDES permit.
(i) Heat in amounts which will inhibit biological activity in the POTW, but in no case heat in such quantities that the temperature at the POTW exceeds 40 degrees C (104 degrees F) unless the Approval Authority, upon request of the POTW, approves alternate temperature limits.
(j) Any slugload.
(k) Any unpolluted water including but not limited to non-contract cooling water.
(l) Any wastewater containing any radioisotopes of such half-life or concentration as exceed limits established by the City of Mansfield.
(m) Sewage containing more than fifty milligrams per liter of grease and oil.
(n) Biochemical oxygen demand, chemical oxygen demand, suspended solids, or nitrogen in concentrations which cause damage or interference to the POTW or the risk thereto.
(o) Flows of magnitude of variation which cause damage or interference to the POTW or the risk thereto.
(p) Any "pass through" of the wastewater treatment plant.
(q) Waters or wastes containing substances which are not amenable to treatment or reduction by the wastewater treatment processes employed, or are amenable only to such degree that the wastewater treatment plant effuent cannot meet the requirements of other agencies having jurisdiction over discharge to the receiving waters.
