(a) No wastes shall be discharged, either directly or indirectly, into any sewer within the City Sewer Service Area without prior approval from the Village.
(b) 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 POTW. These general prohibitions apply to all such Users of a POTW whether or not the User is subject to National Categorical Pretreatment Standards or any other national, State, or local Pretreatment Standards or Requirements. A User may not contribute the following substances to any POTW:
(1) 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. They will not constitute a hazard to humans or animals, create a public nuisance, or create any hazard in the receiving waters of a sewage treatment plant, including but not limited to those metals or toxic substances mentioned in this chapter as discharge to the public sewer. 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 five percent (5%) nor any single reading over ten percent (10%) 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, peroxides, chlorates, perchlorates, bromates, carbides, hydrides and sulfides and any other substances which the Village, the State or EPA has notified the User is a fire hazard or a hazard to the system.
(2) Solid or viscous substances which may cause obstruction to the flow in a sewer or other interference with the operation of the wastewater treatment facilities such as, but not limited to: grease, garbage with particles greater than one-half inch (½") in any dimension, animal guts or tissues, paunch manure, bones, hair, hides or fleshings, entrails, whole blood, feathers, ashes, cinders, sand, spent lime, stone or marble dust, metal, glass, straw, shavings, grass clippings, rags, spent grains, spent hops, waste paper, wood, plastics, gas, tar, asphalt residues, residues from refining, or processing of fuel or lubricating oil, mud, or glass grinding or polishing wastes.
(c) 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 Village Administrator that such wastes can harm either the sewers, sewer system or equipment, sewage treatment process or equipment, or have an adverse effect on the receiving stream, or can otherwise endanger life, limb, public property, or constitute a nuisance. Informing his opinion as to the acceptability of these wastes, the Village Administrator shall 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 of the sewage treatment process, capacity of the sewage treatment plant, degree of treatability of wastes in the sewage treatment plant, and other pertinent factors. The substances prohibited are:
(1) Maximum allowable temperature into sewers or waterways. Any liquid or vapor having a temperature higher than 150 degrees F., or causing the temperature at the treatment facility to exceed 104 degrees F.
(2) Maximum allowable ether solubles. Any water or waste containing fats, wax, grease, or oils whether emulsified or not, in excess of eighty mg/l ether soluble or containing substances which may solidify or become viscous at temperatures between 32 degrees F. and 140 degrees F.
(3) Regulation of garbage grinders. Any garbage that has not been properly shredded. The installation and operation of any garbage grinder equipped with a motor of three-fourth horsepower (0.76 hp metric) or greater shall be subject to the review and approval of the Village Administrator.
(4) Prohibition of acid and plating wastes. Any waters or wastes containing strong acid wastes, or concentrated plating solutions whether neutralized or not, are prohibited.
(5) Maximum metal concentrations. Any water or wastes containing iron, chromium, copper, zinc, or similar objectionable or toxic substances, or wastes exerting an excessive chlorine requirement, to such degree that any such material received in the composite sample at the wastewater treatment works exceed the limits established by the Village Administrator or this chapter for such materials. Materials such as copper, zinc, chromium, or similar toxic substances shall be limited to the following average quantities in the sewage as it enters the POTW. Concentration at the wastewater treatment plant shall not exceed three times the average concentration:
Material | Parts per Billion |
Arsenic | 50 |
Barium | 800 |
Cadmium | 5 |
Chromium | 300 |
Copper as Cu | 500 |
Iron | 1000 |
Lead | 40 |
Mercury | .5 |
Zinc as Zn | 1000 |
and with contributions from individual establishments subject to control in volume and concentration by the Village Administrator.
(d) Permissible Cyanide Levels. Maximum cyanide to be accepted into sewer system will be one milligram per liter with no dilution and five milligrams per liter with high dilution. Both stated figures shall be regulated at the discretion of the Village Administrator.
(e) Prohibition of Taste or Odor Causing Substance. Any waters or wastes containing phenols or other taste or odor-producing substances, in such concentrations exceeding limits which may be established by the Village Administrator as necessary, 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, are prohibited. Any waters or wastes that contain phenols in excess of 0.40 parts per million by weight are prohibited (400 parts per billion). These limits may be modified by the Village Administrator if the aggregate of contributions throughout the Mingo Junction area of service create treatment difficulties, or produce a plant effluent discharge to receiving waters, which may be prohibitive.
(f) Prohibition of Radioactive Wastes. Any radioactive wastes or isotopes of such half-life (over 100 days) or concentration as may exceed limits established by the Village Administrator in compliance with applicable State or Federal regulations. The radioactive isotopes I131 and p32 used at hospitals are not prohibited, if properly diluted at the source.
(g) Prohibition of Corrosive Wastes. Any water or wastes, acid or alkaline in reaction, and having corrosive properties capable of causing damage or hazard to structures, equipment or personnel of the Mingo Junction Water Pollution Control System. Any waters or wastes having a pH lower than 5.5. Any water or waste having a pH higher than 9.0. Free acids and alkalis of such waste must be neutralized at all times.
(h) Prohibition of Noxious Substances. Any noxious or malodorous gas or substance, which either singly or by interaction with other waste, is capable of creating a public nuisance or hazard to life or of preventing entry into sewers for their maintenance or repair, are prohibited.
(i) Prohibition of Excessive Waste Concentration. Materials which exert or cause:
(1) Abnormal concentrations of inert suspended solids (such as, but not limited to, Fullers earth, lime slurries, and lime residue) or of inert dissolved solids (such as, but not limited to, sodium chloride, calcium chloride and sodium sulfate) from ion exchange softeners.
(2) Excessive discoloration (such as, but not limited to, dye wastes and vegetable tanning solutions).
(3) Abnormal BOD, chemical oxygen demand, suspended solids, phosphorus or chlorine requirements in such quantities as to constitute a significant load on the wastewater treatment works.
(4) Unusual volume of flow or concentration of wastes constituting "slugs" as defined herein. 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 minutes more than three times the average twenty-four hour concentration, quantities, or flow during normal operation.
(j) Prohibition of Non-Treatable Wastes. Waters or wastes containing substances which are not amenable to treatment or reduction by the wastewater treatment processes employed, or are amenable to treatment only to such degree that the wastewater treatment plant effluent cannot meet the requirements of other agencies having jurisdiction over discharge to the receiving waters.
(k) Any substance which will cause the Village wastewater plant to violate its NPDES and/or State Disposal System Permit or the receiving water quality standards.
(l) Any wastewater having a temperature which will inhibit biological activity in the Village wastewater treatment plant resulting in interference, but in no case wastewater with a temperature at the introduction into the wastewater plant which exceeds 30°C. (85°F.).
(m) Any wastewater containing toxic pollutants in sufficient quantity, either singly or by interaction with other pollutants, to injure or interfere with any wastewater treatment process, constitute a hazard to humans or animals, create a toxic effect in the receiving waters of the wastewater treatment plant, or to exceed the limitation set forth in a Categorical Pretreatment Standard. A toxic pollutant shall include, but not be limited to, any pollutant identified pursuant to Section 307(a) of the Act.
(n) If any waters or wastes are discharged, or are proposed to be discharged to the public sewer, which waters contain the substances or possess the characteristics enumerated herein, and which in the judgement of the Village Administrator may have a deleterious effect upon the sewage works, processes, equipment, or receiving waters, or which otherwise create a hazard to life or constitute a public nuisance, the Village Administrator may:
(2) Reject the wastes specified in this chapter.
(3) Require pretreatment to an acceptable condition for discharge to the public sewers.
(4) Require control over the quantities and rates of discharge to an acceptable condition.
(5) Require payment to cover the added cost of handling and treating extra strength wastes or unusual discharges not covered by existing taxes or sewer charges.
(o) 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 chapter for sources in that subcategory, shall immediately supercede the limitations imposed under this chapter. The Village Administrator shall notify all affected Users of the applicable reporting requirements under 40 CFR, Section 403.12.
(p) No user shall ever increase the use of process water or attempt to dilute a discharge as a partial or complete substitute for adequate treatment to achieve compliance with Categorical Pretreatment Standards or those developed by the State or Village.
(q) No statement contained in this section shall be interpreted as preventing any special agreement or arrangement between the Village and any industrial concern whereby an industrial waste of unusual strength or character may be accepted by the Village for treatment. In all such cases, the provisions set forth in the Village ordinance establishing charges will be governing factors in any contracts entered into.
(r) Every person, firm or corporation whose premises are served by a sanitary sewer connection and discharges wastes other than "domestic sewage" into the sewerage system of the Village shall be charged and shall pay a Sewage Surcharge in addition to the Sewer Service Charge for "domestic sewage."
Such surcharge shall be based on four constituents of the water or wastes applicable:
(1) Total Suspended Solids.
(2) B.O.D., five days at 20 degrees Centigrade.
(3) C.O.D., potassium dichromate-sulfuric acid oxidation.
(4) Phosphorus.
Whenever the wastes are ruled acceptable to wastewater treatment and the wastewater contains suspended solids, B.O.D., and/or C.O.D., or phosphorus in excess of "domestic sewage", the excess shall be subjected to a surcharge derived in accordance with the following formula:
SC = (SS-280) x F x 8.34 x C + (BOD-240) x F x 8.34 x Cb =
F x 8.34 [(SS-280)Cs + (BOD-240)Cb].
SC = Total surcharge based on average daily flow.
SS = Total suspended solids in wastes as discharged in milligrams per liter.
280 = Suspended solids concentration in "domestic sewage" in milligrams per liter.
F = Flow in millions of gallons per day of wastes as discharged.
Cs = Cost to treat one pound of suspended solids in cents per pound. Total OM & R
cost attributable to SS (25%)/Total pounds suspended solids removed.
BOD = Total B.O.D. in wastes as discharged in milligrams per liter.
240 = B.O.D. concentration in "domestic sewage" in milligrams per liter.
Cb = Cost to treat one pound of B.O.D. in cents per pound. Total OM & R cost
attributable to BOD (25%)/Total pounds B.O.D. removed.
OR
SC = (SS-280) x F x Cs + (COD-500) x F x 8.34 Cc =
F x 8.34 [(SS-280/Cs + (COD-500) Cc]
COD = Total C.O.D. in wastes as discharged in milligrams per liter.
500 = C.O.D. concentration in "domestic sewage" in milligrams per liter.
Cc = Cost to treat one pound of C.O.D. in cents per pound per day.
Cc = Total operation cost attributable to COD/Total pounds C.O.D. removed.
OR
SCp = (P-10) x 8.34 x F x Cp
P = Total phosphorus in wastes as discharged in milligrams per liter.
10 = Total phosphorus concentration in "domestic sewage" in milligrams per liter.
F = Flow in millions of gallons per day.
Cp = Cost to treat one pound of phosphorus in cents per pound per day.
Whenever a waste cannot be analyzed by a B.O.D. test, the C.O.D. result shall prevail in calculating the Surcharge. Whenever both testing methods are possible, the Superintendent shall determine which analysis shall apply in computing the Surcharge based on which will provide the higher Surcharge.
(s) The Village Administrator shall, on or before February 1, of each year, review the Strength Surcharge for the Water Pollution Control Department the previous year. Increases or decreases in the cost of treating and disposing of excess amounts of B.O.D., suspended solids, C.O.D. and phosphorus shall be reflected on a proportionate basis in the Strength Surcharge on the basis of cost per pound. Increases or decreases in the actual cost of gathering samples, testing and reporting the results of analysis done on industrial sewage shall be reflected on a proportionate basis. Changes in the Strength Charge as determined by the Village Administrator shall be approved by a majority of Council.
(t) The costs to treat the B.O.D., C.O.D., suspended solids, or phosphorus will be based on those portions of the total OM & R cost of the sewerage works attributable to BOD, SS, and COD. These costs shall be adjusted annually to remain current with the OM & R costs and shall be submitted to Council for approval and passage in ordinance form.
(u) Any person who fails to pay the proper Surcharge shall reduce the level of their waste to the strength of "normal sewage". Failure to reduce the level of waste to "normal sewage" or failure to terminate operations within sixty days after written notification thereof shall be considered to be a misdemeanor and, upon conviction thereof, shall be fined not less than one hundred dollars ($100.00) nor more than five hundred dollars ($500.00) per day; each day shall constitute a separate violation.
