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 treatment plant. These general prohibitions apply to all such users of the treatment plant whether or not the user is subject to National Categorical Pretreatment Standards or any other National, State, or local pretreatment standards or requirements. The following limitations and prohibitions shall apply to all users of the treatment plant:
A. No person shall directly or indirectly discharge or cause to be discharged any stormwater, surface water, foundation drain water, groundwater, roof runoff, surface drainage, or unpolluted industrial cooling water to any sewer connection to the authority’s wastewater treatment plant. All connections which would result in the discharge of infiltration or inflow are hereby specifically prohibited.
B. Except as otherwise provided, discharge of wastewaters into the sewer system containing any one of the following constituents is hereby prohibited:
(1) Containing more than 15 mg/l of petroleum oils, non-biodegradable cutting oils, or other products of mineral oils origin.
(2) Containing more than 100 mg/l of fats, oils or grease or other products of an animal or vegetable origin.
C. Except as otherwise provided, no person shall discharge or cause to be discharged any waste or other matter or substance:
(1) Having a temperature higher than 150 degrees Fahrenheit or less than 32 degrees Fahrenheit, or containing heat in amounts which will inhibit biological activity in the treatment plant resulting in interference; but, in no case heat in such quantities that the temperature of the in fluent to the treatment plant exceeds 104 degrees Fahrenheit.
(2) Containing any liquids, solids or gases which by reason of their nature or quantity are, or may be, sufficient either alone or in interaction with other substances to cause fire or explosion or may be injurious in any other way to the treatment plant. At no time shall two successive readings on an explosion hazard meter, at the point of discharge into the system (or at any point in the system) be more than 5 percent, nor any single reading over 10 percent, of the lower explosive limit (LEL) of the meter. Prohibited materials include, but are not limited to, gasoline, kerosene, naphtha, benzene, toluene, xylene, ethers, alcohols, ketones, aldehydes, peroxide, chlorates, perchlorates, bromates, carbides, hydrides and sulfides and any other substances which the Authority, the Commonwealth of Pennsylvania or EPA has notified the user is a fire hazard or a hazard to the system.
(3) Containing any noxious or malodorous gas or substance, which either singly or by interaction with other wastes, is capable of creating a public nuisance or hazard to life or preventing entry into sewers for their maintenance or repair.
(4) Containing garbage that has not been ground to such a degree that all particles will be carried freely in suspension under flow conditions normally prevailing in the sanitary sewers, with no particles under any circumstance, greater than ½ inch in any dimension.
(5) Containing any solid or viscous substances in quantities or of size capable of causing obstruction to the flow in sewers, or other interference with the proper operation of the wastewater facilities. Such substances include, but are not limited to, ashes, cinders, sand, mud, straw, shavings, metal, glass, bones, rags, feathers, tar, plastic, wood, paunch manure, butchers offal, whole blood, bentonite, lye, building materials, rubber, hair, leather, porcelain, china, ceramic wastes, asphalt, paint and waxes.
(6) Having a pH, stabilized, lower than 6.0 or higher than 9.0 or having a corrosive or scale forming property capable of causing damage or hazards to structures, equipment, bacterial action, or health or safety hazards to operating personnel of the sewer system or the wastewater treatment plant.
(7) Containing a toxic or poisonous substance in sufficient quantity, either singly or by interaction with other pollutants, to injure or interfere with any sewage treatment process, to constitute a hazard to humans or animals or to create any hazard in the receiving stream of the sewage treatment plant; or to exceed the limitation set forth in a categorical pretreatment standard; limiting the concentration in mg/l of the following ions in the discharges into the sanitary sewer system to:
(a) | Arsenic | 0.04 mg/l. |
(b) | Cadmium | 0.90 mg/l. |
(c) | Chromium (total) | 9.0 mg/l. |
(d) | Chromium (hexavalent) | 1.0 mg/l. |
(e) | Copper | 1.0 mg/l. |
(f) | Cyanides | 0.08 mg/l. |
(g) | Lead | 0.10 mg/l. |
(h) | Mercury | 0.10 mg/l. |
(i) | Nickel | 0.90 mg/l. |
(j) | Zinc | 1.0 mg/l. |
(8) Containing any substance which may cause the treatment plant effluent or any product of the treatment plant such as residues, sludges, or scums, to be unsuitable for reclamation and reuse or to interfere with reclamation process. In no case shall the substance discharged to the treatment plant cause the treatment plant to be in noncompliance with any criteria, guidelines, or regulations affecting the sludge use or disposal developed pursuant to the Solid Waste Disposal Act, 42 U.S.C. §6962, or Commonwealth of Pennsylvania criteria applicable to the sludge management method being used.
(9) Containing total solids of such character and quantity that unusual attention or expense is required to handle such materials at the sewage treatment plant, except as may be approved by the authority, or as may be otherwise provided herein.
(10) Containing any toxic radioactive isotopes.
(11) Containing color from any source that when diluted with distilled water 1 to 10 will have a luminescence of 10 percent or better and a purity of 90 percent or less, at its dominant wave length by the tristimulus method.
(12) Having a chlorine demand in excess of 10 mg/l.
(13) Prohibited by any permit by the Commonwealth of Pennsylvania, or by the U.S. Environmental Protection Agency or any other Federal agency.
(14) Containing wastes which are not amenable to biological treatment or reduction in existing treatment facilities, specifically non-biodegradable complex carbon compounds.
(15) Quantities of flow or concentrations, or both, which constitute a “slug” as defined in this Part.
(16) Any waters which are used for the purpose of diluting wastes which would otherwise exceed applicable maximum concentration limitations.
(17) Ammonia nitrogen in such an amount that would cause the authority to be in noncompliance with regulations of the Commonwealth of Pennsylvania.
(18) Wastes containing more than 10 milligrams per liter of hydrogen sulfide, sulfur dioxide, nitrous oxide or any of the halogens.
D. No provision in this Section shall be construed to provide lesser discharge standards than are presently or may hereafter be imposed and required by the U.S. Environmental Protection Agency or the Commonwealth of Pennsylvania.
E. Nothing in this Section shall be construed as preventing any special agreement or arrangement between the Borough and any user of the treatment works whereby wastewater of unusual character is accepted for treatment should such wastewater be deemed by the Borough to be acceptable for treatment without harm to the treatment works or people operating it and should such wastewater be in compliance with categorical pretreatment standards and all other appropriate local, State and Federal regulations.
F. Upon the promulgation of the Federal Categorical Pretreatment Standards for a particular industrial subcategory, the Federal standard, if more stringent than limitations imposed under this Part for sources in that subcategory, shall immediately supersede the limitations imposed under this Part. Where a user, subject to a National Categorical Pretreatment Standard, has not previously submitted an application for a permit, the user shall apply for a permit, and the user shall apply for such a permit within 180 days.
G. Unless special permission is granted by the Borough, no user shall ever increase the use of process water or, in any way, attempt to dilute a discharge as a partial or complete substitute for adequate treatment to achieve compliance with the limitations contained in the Federal Categorical Pretreatment Standards, or in any other pollutant-specific limitation developed by the authority or the Commonwealth of Pennsylvania.
