Except as otherwise provided in the pretreatment standards adopted by the City in Section 1040.11, no person shall discharge into the public sanitary sewerage system industrial wastes having any of the following characteristics:
(a) Wastes containing liquids, solids or gases which by reason of their nature or quality may cause fire or explosion or be in any other way injurious to persons, the structures of the public sanitary sewerage system or its operation.
(b) Wastes having a temperature in excess of 150 degrees Fahrenheit or less than thirty-two degrees Fahrenheit.
(c) Wastes having a pH lower than 5.5 or higher than 9.5 or having any corrosive property capable of causing damage or hazard to structures, equipment or personnel of the public sanitary sewerage system. Where Council deems it advisable, it may require any person discharging industrial wastes to install and maintain, in an approved manner, a suitable device to continuously measure and record the pH of the wastes so discharged.
(d) Wastes containing any noxious or malodorous gas or substance which either singly or by interaction with sewage or other wastes is likely, in the opinion of Council, to create a public nuisance or hazard to life or prevent entry to sewers for their maintenance and repair;
(e) Wastes containing ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, hair, chemical or paint residues, greases, lime slurry or viscous material of such character or in such quantity as, in the opinion of Council, may cause an obstruction to the flow in sewers or otherwise interfere with the proper operation of the public sanitary sewerage system. Attention is called to the fact that the maximum permissible concentration will vary throughout the system, depending upon the size of the particular receiving sewer and the flows therein.
(f) Wastes containing insoluble, nonflocculent substances having a specific gravity in excess of 1.5;
(g) Wastes containing soluble substances in such concentrations as to cause the specific gravity of the waste to be greater than 1.1;
(Ord. 9-60. Passed 2-23-60.)
(h) Wastes containing any of the following substances in concentrations exceeding those shown in the following table:
Maximum Permissible Concentration(mg/1)
Oil and Grease
Total Toxic Organics
32 to 120 F
*The term TTO shall mean Total Toxic Organics, which consist of the following parameters. The concentration of TTO is the summation of all quantifiable parameters greater than 0.01 milligrams per liter:
2-Chloroethyl Vinyl Ether
Benzo (a) anthracene
Benzo (b) pyrene
Benzo (b) fluoranthene
Benzo (g,h,i) perylene
Benzo (k) fluroanthene
bis (2-chloroethoxy) methane
bis (2-chloroethoxy) ether
bix (2-chloroisopropyl) ether
bis (2-ethylhexyl) phthalate
4-Bromophenol phenyl ether
Butyl Benzyl phthalate
4-chlorophenol phenyl ether
Ideno (1,2,3-cd) Pyrene
(Ord. 13-00. Passed 7-20-00; Ord. 08-05. Passed 5-31-05.)
(i) Wastes containing more than 100 p.p.m. by weight of fat, oil or grease;
(j) Wastes containing more than ten p.p.m. of any of the following gases: hydrogen sulfide, sulfur dioxide, nitrous oxide or any of the halogens; Wastes containing gases or vapors, either free or occluded, in concentrations toxic or dangerous to humans or animals;
(k) Any waste containing toxic substances in quantities sufficient to interfere with the biochemical processes of the sewage treatment works or that will pass through the sewage treatment works and exceed the State requirements for the Shenango River;
(l) Any waste containing toxic radioactive isotopes without a special permit.
