(a) No person shall discharge or cause to be discharged any storm water, surface water, ground water, roof run-off, subsurface drainage, cooling water or unpolluted industrial process waters to any sanitary sewer.
(b) Storm water and all other unpolluted drainage shall be discharged to such sewers as are specifically designated as combined sewers or storm drains, or to a natural outlet approved by the Administrator. Industrial cooling water or unpolluted process waters may be discharged, upon approval of the Administrator, to a storm drain, combined sewer or natural outlet.
(c) Whenever a combined sewer is replaced with a separate sanitary sewer and a separate storm drain, connections to such combined sewer shall be disconnected. Owners of abutting properties shall then arrange to connect their facilities to the separate systems provided at their sole cost and expense in accordance with the provisions of this chapter.
(d) Except as hereinafter provided, no person, firm or corporation shall discharge or cause to be discharged any of the following described waters or wastes to any public sewer:
(1) Any liquid or vapor having a temperature higher than 150°F.
(2) Any water or waste which contains more than 150 parts per million, by weight, of either soluble fats, oil, emulsions or grease.
(3) Any gasoline, benzene, naphtha, fuel oil or other flammable or explosive liquid, solid or gas.
(4) Any garbage that has not been properly shredded.
(5) Any ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastic, wood, paunch manure, or any other solid or viscous substance capable of causing obstruction to the flow in sewers or other interference with the proper operation of the sewage works.
(6) Any waters or wastes having a pH lower than 6.0 or higher than 9.0, or having any other corrosive property capable of causing damage or hazard to structures, equipment and personnel of the sewage works.
(7) Any wastes or waters containing a toxic or poisonous substance in sufficient quantity to injure or interfere with any sewage treatment process, constitute a hazard to humans or animals, or create any hazard or pollution in the receiving waters of the sewage treatment plant, such as cyanides, radio- active substance, isotopes, and similar materials.
(8) Any waters or wastes containing suspended solids of such character and quantity that unusual attention or expense is required to handle such materials at the sewage treatment plant, or having a chlorine demand greater than 30 mg/l.
(9) Any noxious or malodorous gas or substance capable of creating a public nuisance, or substances causing the release of noxious or poisonous gases after discharge into the public sewer system.
(10) The limits at the industry’s sewer outlet for plating wastes, toxic wastes, greases, oils and oil emulsions will be stipulated in individual contracts between the Village and the industry at the time the industry requests permission to use the Village’s sanitary sewer system for the discharge of its industrial waste. Said limits shall be calculated and determined by the Village for each industry in a manner to assure that the concentrations of the several wastes at the sewage treatment works will not exceed those stipulated in subsection (d)(11) hereof when diluted with sewage.
Under no conditions will the discharge of concentrated plating baths or acid pickling liquor to the sanitary sewer system be permitted.
(11) The limits of toxic wastes discharged into the public sanitary sewer system shall not exceed the following tentative limits as received at the treatment works:
Iron |
15 ppm |
Zinc |
2 ppm |
Cyanide |
1 ppm |
Copper |
1 ppm |
Nickel |
3 ppm |
Chromium (hexavalent) |
2 ppm |
Chromium (trivalent) |
1 ppm |
Phenols |
10 ppm |
Lead |
0.5 ppm |
Cadmium |
4 ppm |
If the concentration of any industrial wastes exceeds the limits stipulated above, as received at the municipal sewage treatment plant, the largest contributor of such waste(s) followed in order by the next largest contributors shall reduce, by acceptable pretreatment and/or flow regulation or both, the amounts wasted to the public sewer until the aggregate of any such waste concentration at the treatment works shall not exceed the above prescribed limits.
(e) (1) Grease, oil and sand interceptors shall be provided when, in the opinion of the Administrator, they are necessary for the proper handling of liquid wastes containing grease in excessive amounts, or any inflammable wastes, sand and other harmful ingredients; except that such interceptors shall not be required for private living quarters or dwelling units. All interceptors shall be of a type and capacity approved by the Administrator, and shall be located as to be readily and easily accessible for cleaning and inspection.
(2) Grease and oil interceptors shall be constructed of impervious materials capable of withstanding abrupt and extreme changes in temperature. They shall be of substantial construction, watertight and equipped with easily removable covers which when bolted in place shall be gastight and watertight.
(f) Where installed, all grease, oil and sand interceptors shall be maintained by the owner, at his expense, in continuously efficient operation at all times.
(g) The admission into the public sewers of any waters or wastes having (1) a 5-day Biochemical Oxygen Demand greater than 200 parts per million by weight, or (2) containing more than 250 parts per million by weight of suspended solids, or (3) containing any quantity of substances having the characteristics described in subsection (d), or (4) having an average daily flow greater than two percent (2%) of the average daily sewer flow from the Village, subject to the review and approval of the Administrator. Where necessary in the opinion of the Administrator, the owner shall provide, at his expense, such preliminary treatment as may be necessary to, (1) reduce the Biochemical Oxygen Demand to 200 parts per million and the suspended solids to 250 parts per million by weight, or (2) reduce objectionable characteristics or constituents to within the maximum limits provided in subsection (d), or (3) control the quantities and rates of discharge of such waters or wastes. Plans, specifications and any other pertinent information relating to proposed treatment facilities shall be submitted for the approval of the Superintendent and of the Water Pollution Control Commission of the State of Ohio, and no construction of such facilities shall be commenced until said approvals are obtained in writing.
(h) Where any treatment facilities are provided for any waters or wastes, they shall be maintained continuously in satisfactory and effective operation, by the owner of such treatment facilities at his expense.
(i) When required by the Administrator, the owner of any property served by a building sewer carrying industrial wastes shall install a suitable control manhole in the building sewer to facilitate observation, sampling and measurement of the wastes. Such manholes, when required, shall be accessibly and safely located, and shall be constructed in accordance with plans approved by the Administrator. The manhole shall be installed by the owner at his expense, and shall be maintained by him so as to be safe and accessible at all times.
(j) All measurements, tests, and analyses of the characteristics of waters and wastes to which reference is made in subsection (d) and (g) shall be determined in accordance with the latest “Standard Methods for the Examination of Water and Sewage”, published by USPH Service and shall be determined at the control manhole provided for in subsection (i), or upon suitable samples taken at said control manhole. In the event that no special manhole has been required, the control manhole shall be considered to be the nearest downstream manhole in the public sewer to the point at which the building sewer is connected.
(k) No statement contained in this chapter will be construed 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, subject to a surcharge payment therefor by the industrial concern as established in subsection (l).
(l) Where it has been determined by the Administrator that industrial waste of unusual or extra strength may be accepted for treatment without detriment to the Village sewage works, said industrial waste of unusual or extra strength may be discharged providing that:
(1) The owner shall comply with subsections (i) and (j) hereof, and
(2) Shall pay the added costs of receiving, conveying and treating all wastes which exceed either by volume or content normal sewage limitations by and through the multiplier factor of regular charges as determined by the following formula:
F = 1+ R (SS - 250) + R (BOD - 200)
500 300
Where:
F equals the multiplier factor of regular rates
R equals the ratio of expense for treatment to the total system expense
SS equals strength of discharge in mg/l of SS
BOD equals strength of discharge in mg/l of BOD
(m) (1) Users shall notify the Administrator immediately upon accidentally discharging wastes in violation of this chapter to enable countermeasures to be taken by the Village to minimize damage to the community sewer, treatment facility, treatment processes and the receiving waters.
(2) This notification shall be followed, within fifteen days of the date of occurrence, by a detailed written statement describing the causes of the accidental discharge and the measures being taken to prevent future occurrence.
(3) Such notification will not relieve users of liability for any expense, loss or damage to the sewer system, treatment plant, or treatment process, or for any fines imposed on the Village on account thereof.
(4) In order that employees of users be informed of Village requirements, users shall make available to their employees copies of this chapter together with such other wastewater information and notices which may be furnished by the Village from time to time directed toward more effective water pollution control. A notice shall be furnished and permanently posted on the user’s bulletin board advising employees whom to call in case of an accidental discharge in violation of this chapter.
(5) Any direct or indirect connection or entry point for persistent or deleterious wastes to the user’s plumbing or drainage system should be eliminated. Where such action is impractical or unreasonable, the user shall appropriately label such entry points to warn against discharge of such wastes in violation of this chapter.
