1040.13  PROHIBITED DISCHARGES GENERALLY.
   Except as provided in this chapter, no person shall discharge or cause to be discharged to any public sewer, ditch, drain or culvert any of the following:
   (a)   Any water, waste or vapor containing heat in an amount which will accelerate the biodegradation of wastes, cause the formation of excessive amounts of hydrogen sulfide in the sewerage works or inhibit biological activity in the wastewater treatment plant.  In no case shall a heated discharge cause the temperature in the public sewer to exceed sixty-five degrees Celsius (150 degrees Fahrenheit), or cause the temperature of the influent at the treatment plant to exceed forty degrees Celsius (104 degrees Fahrenheit);
   (b)   No person shall discharge, or cause to be discharged, directly or indirectly, any substance which causes an interference or pass through of the POTW, or which disrupts or inhibits the POTW, its treatment processes, operations, or its sludge processes, use, or disposal. No person shall discharge, or cause to be discharged, directly or indirectly, any substance, which constitutes a slugload.  No person shall discharge or cause to be discharged, directly or indirectly, any of the following described substances into the sewer system: any solid or viscous substance capable of causing obstruction to the flow in the sewers, or other interference with the proper operation of the sewer system, for example, but not limited to: construction materials, ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, wood, plastic, fur, wax and/or fat, oils and greases;
(Ord. 09-14.  Passed 4-6-09; Ord. 12-44. Passed 12-17-12.)
   (c)   Any water or wastes containing over 200 mg/l of hydrocarbon fog. “Hydrocarbon fats, oils and grease” means those substances as detected and quantified by the SGT-HEM portion of USEPA Method 1664;
(Ord. 09-14.  Passed 4-6-09; Ord. 12-44. Passed 12-17-12.)
   (d)   Any water or wastes containing petroleum oil, nonbiodegradable cutting oil or products of mineral oil origin if discharged in amounts that can pass through or cause interference. Industrial cooling water which may be polluted with insoluble oils, grease or suspended solids shall be pretreated to remove the pollutants, and the resultant wastewater shall be discharged according to the provisions of Section 1040.12;
   (e)   Any water or wastes which will create a fire or explosion hazard, including, but not limited to, gasoline, benzene, naphtha, fuel oil or other flammable or explosive liquid, solid or gas, or any wastestreams with a closed-cup flashpoint of less than 140 degrees Fahrenheit or sixty degrees Centigrade as determined by the test method specified in 40 CFR 261.21;
   (f)   Any water or waste containing more than ten mgll of hydrogen sulfide, sulfur dioxide or nitrous oxide;
   (g)   Any garbage that has not been properly shredded to a degree that all particles will be carried freely under normal flow conditions prevailing in the public sewer;
   (h)   Any water or wastes containing phenolic compounds in excess of 40.00 mg/l.  These limits may be modified if the aggregate of contributions throughout the service area creates treatment difficulties or produce a prohibitive effluent discharge to receiving waters. 
(Ord. 91-59.  Passed 10-21-91; Ord. 12-44. Passed 12-17-12.)
   (i)   Any water or waste, acid or alkaline in reaction, having corrosive properties capable of causing damage or hazard to structures, equipment and personnel of the Division of Water and Sanitary Sewage. Free acids or alkalies of such a waste must be neutralized at all times, within the permissible pH range of six to twelve.
(Ord. 98-48. Passed 10-19-98.)
   (j)   Any water or waste containing strong acid iron pickling wastes or concentrated plating solution, whether neutralized or not;
   (k)   Any water or waste which results in the presence of toxic or poisonous solids, liquids, gases, vapors or fumes within the POTW in sufficient quantity, either singly or by interaction with other wastes, to cause acute worker health and safety problems; to pass through or cause an interference which inhibits or disrupts the sewage works; to constitute a hazard to animals; to create a public nuisance; to prevent entry into the sewers for maintenance and repair; to cause the treatment plant effluent, residues, sludges or scums to be unsuitable for reclamation and reuse; or to cause a violation of any requirement of the POTW's NPDES permit.
   (l)   Any water or waste containing suspended solids of such a character and quantity that unusual provisions, attention or expense is required to handle such solids at the wastewater treatment plant;
   (m)   Any slugload of any pollutant, including oxygen-demanding pollutants, released in a single extraordinary discharge episode of such a volume or strength as to cause interference in the sewerage works;
   (n)   Any water or waste containing more than 0.02 mgll total identifiable chlorinated hydrocarbons; or
   (o)   Any water or waste which causes a detrimental environmental impact or causes the quality of the wastewater treatment plant effluent to violate the NPDES permit limitations or applicable water quality standards.
