No industrial user shall discharge or cause to be discharged, directly or indirectly, any of the following described substances into the wastewater disposal system or otherwise to the facilities of the Authority:
(a) Any solids, liquids or gases which, by themselves or by interaction with other substances, may cause fire or explosion hazards, including, but not limited to, waste streams with a closed cup flashpoint of less than 140°F or 60°C using the test method specified in 40 C.F.R. Part 261.21;
(b) Any noxious or malodorous solids, liquids or gases, which, either singly or by interaction with other substances, are capable of creating a public nuisance or hazard to life, or preventing entry into sewers for their maintenance and repair;
(c) Any solids, greases, slurries or viscous material of such character or in such quantity that may cause an obstruction to the flow in the sewer or otherwise cause interference;
(d) Any discharge which will cause the Authority’s facilities to violate its NPDES and/or other disposal system permits;
(e) Any discharge that causes or contributes to interference or pass through of the treatment plant;
(f) Any liquids having a pH lower than 6.0 or higher than 12.0, or having any corrosive property capable of causing damage or hazard to structures, equipment or personnel of the sewage disposal works;
(g) Any discharge which may cause the sewage treatment plant’s treatment residues, sludges or scums to be unsuitable for reclamation and re-use or disposal or to interfere with the reclamation or disposal process in use or contemplated for use;
(h) Any wastewater having a temperature which will inhibit biological activity at the sewage treatment plant, resulting in interference, but in no case wastewater with a temperature at the introduction into the treatment plant which exceeds 40°C (104°F);
(i) Any discharge with objectionable color not removed in the treatment process, such as, but not limited to, dye, wastes and vegetable tanning solutions;
(j) Any pollutant, including oxygen demanding pollutants (BOD and the like) released in a discharge at a flow rate and/or pollutant concentration which will cause interference or pass through or which is a slug load;
(k) Any unpolluted water, including, but not limited to, non-contact cooling water;
(l) Any wastewater containing any radioactive wastes or isotopes of such half-life or concentration as exceed limits established in compliance with applicable state or federal regulations;
(m) Any wastewater which causes a hazard to human life, creates a public nuisance or is in any other way injurious to persons, property, animals or the operation of the sewage disposal works;
(n) Any wastewater containing toxic pollutants in sufficient quantity, either singly or by interaction, to injure or interfere with any wastewater treatment process, constitute a hazard to humans or animals, or exceed the limitations set forth in the national categorical pretreatment standards;
(o) Any garbage, whole, ground or shredded, except as may be allowed and subject to control in volume and concentration by the Authority;
(p) Petroleum oil, nonbiodegradable cutting oil or products of mineral oil origin in amounts that will cause interference or pass through;
(q) Any discharge or pollutants which result in the presence of toxic gases, vapors or fumes in the sewage disposal works in a quantity that may cause acute worker health and safety problems;
(r) Any trucked or hauled pollutants, including industrial and septic wastes, into any location of the sewer disposal works at any time;
(s) Any wastewater exceeding the local limits established by the Water Reclamation Department and approved by Ohio EPA. The local limits currently implemented may be viewed at: https://www.solonohio.org/DocumentCenter/View/12628/Local-Limits-Table
(t) Any wastewater exceeding the daily average concentration for the following parameters is prohibited unless the wastewater is assessed for surcharge:
Pollutant | Daily\Average Concentration (mg/l) |
Pollutant | Daily\Average Concentration (mg/l) |
Ammonia (NH3) | 15 |
Biochemical oxygen demand (BOD) | 250 |
Oil and grease*1,*2 (OG) | 100 |
Phosphorous (total) (TP) | 20 |
Suspended solids (SS) | 300 |
*1 A grab sample, multiple grab samples or a composite sample will be analyzed to determine daily average concentrations for oil and grease. | |
*2 Hexane or a suitable alternative solvent will be used to perform the oil and grease test. | |
(u) Any discharge determined by the Authority to be unacceptable as set forth below:
(1) Contains materials or discharges which would constitute a hazard to life and limb of personnel engaged in inspection, maintenance and operation of the system;
(2) Contains materials or discharges which are toxic as defined in § 1044.02(xx) of this chapter;
(3) Contains materials or discharges which are in any way deleterious to any part of the sewage disposal works;
(4) Contains concentrations of any toxic or deleterious materials or discharges in excess of any limits set thereon in accordance with this chapter;
(5) Causes the Authority to incur additional operating expenses in the handling or treatment thereof;
(6) Is incompatible with the treatment process or inhibits the performance of the treatment process at the Authority’s treatment facility;
(7) Is of such volume or contains such a quantity of solids, or other material load, which would cause the treatment facility to exceed its design capacity;
(8) Causes a treatment facility of the Authority not to meet effluent requirements set by state or federal regulatory agencies or causes, such effluent to have a degradive effect on the receiving body of the facility;
(9) Contains viable pathogenic organisms in such quantity as to be a hazard to public health; and
(10) Causes a treatment facility of the Authority not to meet effluent requirements as established by the Authority’s NPDES permit.
