In addition to the general discharge prohibitions, the following specific pollutants shall not be introduced into the POTW or otherwise to the facilities of the City:
(A) Pollutants which by reason of their nature or quantity may create a fire or explosion hazard or be injurious to the POTW or the operation of the POTW including, but not limited to, wastestreams with a closed cup flashpoint of less than 140° F. or 60° C. using the test methods specified in 40 CFR 261.21.
(B) Pollutants which will cause corrosive structural damage to the POTW, but in no case dischargers with pH lower than 6.0 or higher than 9.5.
(C) Solid or viscous substances in quantities or of such size capable of causing obstruction to the flow in sewers, or other interference with proper operation of the sewage works such as, but not limited to, ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, unground garbage, whole blood, paunch manure, hair and fleshings, entrails and paper dishes, cups, milk containers and the like, either whole or ground by garbage grinders with particles greater than one- half inch in any dimension, or any material which can be disposed of as trash.
(D) Any slug load, which shall mean any pollutant, including oxygen demanding pollutants (BOD and the like) released in a discharge at a flow rate and/or pollutant concentration which may cause interference with the POTW.
(E) Heat in amounts which may inhibit biological activity in the POTW resulting in interference, but in no case heat in such quantities that the temperature at the POTW treatment plant exceeds 40° C. (104° F.) unless the Approval Authority, upon request of the POTW, approves alternate temperature limits.
(F) Petroleum oil, nonbiodegradable cutting oil, or products of mineral oil origin in amounts that may cause interference or pass through.
(G) Pollutants which may result in the presence of toxic gases, vapors, or fumes within the POTW in a quantity that may cause acute worker health and safety problems, injure or interfere with any sewage treatment process, create a public nuisance, or create any hazard in the receiving waters of the sewage treatment plant.
(H) Any trucked or hauled pollutants, except at discharge points designated by the POTW.
(I) Any waters or sewage containing pollutant concentrations greater than those listed on the federal categorical pretreatment standards for a particular subcategory. If the federal standard is more stringent than limitations proposed under this chapter for sources in that subcategory, the federal standards shall immediately supersede the limitations imposed under this chapter. The Superintendent shall notify all affected users of the applicable reporting requirements under 40 CFR Section 403.12.
(J) Any wastewater containing any radioactive waste or isotopes of such half life or concentration as exceeds limits established by the Authority in compliance with applicable state or federal regulations.
(K) Any wastewater with color of sufficient light absorbency to interfere with treatment plant process, prevent analytical determinations, or create any aesthetic effect on the treatment plant effluent, such as, but not limited to, dye wastes and vegetable tanning solutions.
(L) Any discharge into the collection system or the wastewater treatment plant which contains any material in excess of the concentrations allowed by the Local Limits.
(M) Soluble substances in a concentration that increases the viscosity to greater than 10% over the viscosity of water or in amounts that will cause obstruction to the flow in the POTW resulting in interference.
(N) Any solvent extractable, including, without limitation, oil grease, wax, or fat, whether emulsified or not, in excess of applicable local limits; or other substances that solidify or become viscous (with a viscosity of 110% of water) at temperatures between 32 degrees Fahrenheit and 150 degrees Fahrenheit in amounts that cause obstruction to the flow in sewers or other interference with the operation of the POTW.
(O) Any pollutant that results in excess foaming during the treatment process. Excess foaming is any foam that interferes with the treatment process.
(P) Any medical infectious waste.
(Q) Any sludge, precipitate or waste resulting from any industrial or commercial treatment or pretreatment of any wastewater or air pollutants.
(R) Any non-contact cooling water, air-conditioning water, swimming pool water, storm water, surface water, groundwater, roof runoff, and surface or subsurface drainage except as authorized by law, and as approved by the Superintendent.
(S) Any discharge into the collection system or the wastewater treatment plant which contains any material in excess of the concentrations allowed by the Local Limits or that causes the POTW to violate its NPDES permit, the receiving water quality standards, or associated local, state or federal laws, rules, or regulations, or interferes with the reclamation, reuse or disposal process for treatment residues, sludge, or scums.
