Section 710.080 Prohibited Discharges.

[R.O. 2008 §710.080; Ord. No. 5050 §1, 5-11-1992]

No person shall discharge or cause to be discharged the following described substances, materials, waters, or wastes if it appears likely in the opinion of the Director of Public Works, that such wastes can harm the POTW or equipment, have an adverse effect on the receiving stream, or can otherwise endanger life, limb, public property, or constitutes a nuisance. In forming an opinion as to the acceptability of these wastes, the Director of Public Works will give consideration to such factors as the quantities of subject wastes in relation to flows and velocities in the sewers, materials of construction of the sewers, nature and capacity of the POTW, degree of treatability of wastes in the wastewater treatment works and other pertinent factors. But in no case will a federally mandated prohibition be altered to be less stringent. The substances which must be considered include, but are not limited to, the following:

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 to cause fire or explosion or be injurious in any other way to the POTW or to the operation of the POTW. At no time shall two (2) successive readings on an explosion hazard meter, at the point of discharge into the POTW (or at any point in the system) be more than five percent (5%) nor any single reading over ten percent (10%) of the Lower Explosive Limit (LEL) of the meter. Flash point limit of less than 140°F (60°C) shall be observed.

Prohibited materials include, but are not limited to: Gasoline, fuel oil, hexane, kerosene, naphtha, benzene, toluene, xylene, ethers, alcohols, ketones, aldehydes, peroxides, chlorates, perchlorates, bromates, carbides and hydrides.

Any waters or wastes containing toxic or poisonous solids, liquids, or gases in sufficient quantity, either singly or in interaction with other wastes, to injure or interfere with the POTW, constitute a hazard to humans or animals; create a public nuisance, or create any hazard in the receiving waters of the wastewater treatment works. A toxic pollutant shall include, but not be limited to, any pollutant identified pursuant to Section 307 (a) of the Act.

Any herbicides and pesticides.

Any waters or wastes having a pH lower than 5.5 or higher than 9.5, or having any other corrosive property capable of causing damage or hazard to structures, equipment and/or personnel of the POTW.

Solids, natural man-made fibers, insoluble or emulsified oils, fats, greases, slurries or viscous substances in quantities or of such size capable of causing obstruction to the flow in sewers, or other interference with the proper operation of the POTW such as, but not limited to, ashes, cinders, sand, paraffin, mud, straw, shavings, metal, sawdust, glass, rags, feathers, tar, plastics, wood, unground garbage, whole blood, paunch manure, hair and fleshings, paper dishes, cups, milk containers, bones, spent lime, grinding compounds, grass clippings, spent grain, spent hops, asphalt residues, chemical residues, acid residues, entrails, paint residues, whey, food processing bulk solids, etc., either whole or ground by garbage grinders.

Septic tank sludge, and all other trucked or hauled wastes, except that such sludge may be discharged at selected locations as designated for this purpose by the Director of Public Works.

Any substance which may cause the POTW's effluent or any other product of the POTW such as residues, sludge 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 POTW, cause the POTW to be in non-compliance with sludge or disposal criteria, guidelines or regulations developed under Section 405 of the Act; 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 criteria applicable to the sludge management method being used.

Any substance which will cause the POTW to violate its NPDES Permit or the receiving water quality standards.

Any pollutants, including oxygen demanding pollutants (BOD, etc.) released at a flow rate and/or pollutant concentration which a user knows or has reason to know will cause interference to the POTW. In no case shall a slug load have a flow rate or contain concentration or qualities of pollutants that exceed, for any time period longer than fifteen (15) minutes, more than five (5) times the average twenty-four (24) hour concentration, quantities or flow during normal operation. As specified in 40 CFR 403.5(b)(4), the discharge of any pollutant, including oxygen-demanding pollutants (such as Biochemical Oxygen Demand (BOD), released in a discharge at a flow rate or pollutant concentration which will cause interference, is prohibited. The Federal regulations also provide an affirmative defense for a user if that user meets both parts of a two-part test set out in 40 CFR 403.5(a)(2). The user must satisfy two conditions:

It did not know, or have reason to know, that its discharge would cause pass through or interference; and

It was in compliance with existing limits for each pollutant in its discharge; or, if a limit was not enacted for such pollutants(s), its discharge directly before and during the pass through or interference did not change substantially from its prior discharge(s) which occurred when the POTW remained in compliance with its NPDES Permit.

12.

Any waters or wastes containing reducing substances of an organic or inorganic nature, toxic or non-toxic, which exert an immediate chlorine demand, shall not be discharged into the POTW or if the discharge of such agents will prevent the achievement of an adequate chlorine residual in the effluent of the wastewater treatment works.

13.

Any waters or wastes containing phenols or other taste or odor-product substances, in concentrations exceeding limits established by the Director, after treatment of the composite sewage, to meet the requirements of the State, Federal, or other public agencies of jurisdiction for such discharge to the receiving waters. In no case shall any waste contain phenolic compounds in excess of five-tenths milligrams per liter (0.5 mg/l) expressed as phenols.

14.

Any radioactive wastes or isotopes of such half-life or concentrations as may exceed limits established by the Director of Public Works in compliance with applicable State and Federal regulations.
