Legal Documents of Gatlinburg

No person shall discharge or cause to be discharged any of the following, but not limited to, described waters or wastes to any public sewer. The admission of any of the wastes described in this section to the extent and degree forbidden or excluded shall subject such person or user to such corrective action or remedy as is available to the city, and penalties described in § 18-245.

1. Any gasoline, benzene, naptha, fuel oil, or other flammable or explosive liquid, solid or gas.
2. Any waters or wastes containing toxic or poisonous solids, liquids, or gases in sufficient quantity, either singly or by interaction with other wastes, to injury or interfere with any sewage treatment process, constitute a hazard to humans or animals, create a public nuisance, or create a hazard in the receiving waters of the sewage treatment plant.
3. Any waters or wastes having a pH higher than 9.0 or lower than 5.5, or having other corrosive property capable of causing damage or hazard to structures, equipment, and personnel of the sewage works.
4. Solid or viscous substances in quantities or of such size capable of causing obstruction to the flow in sewers, or other interference with the proper operation of the sewage works such as, but not limited to, ashes, cinders, sand, mud, straw, shavings, metal, glass, feathers, tar, plastics, wood, unground garbage, whole blood, paunch manure, air and fleshings, entrails, milk containers, paper dishes, cups, paper and plastic products such as plates, cups, forks, knives, spoons, straws, butter pats, either whole or ground by garbage grinders, and degreasers such as sulfuric acid, or solvents.
5. 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 superintendent that such wastes can harm either the sewers, sewage treatment process, or equipment; have an adverse effect on the receiving stream, or can otherwise endanger life, limb, public property or constitute a nuisance. In forming his opinion as to the acceptability of these wastes, the superintendent will 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, and other pertinent factors. The substances prohibited are:
   1. Any liquid or vapor having a temperature higher than one hundred fifty degrees (150°) F. or 65° C.
   2. Any water or waste containing fats, wax, grease or oils, whether emulsified or not, in excess of fifty milligrams per liter (50 mg/l) or containing substances which may solidify or become viscous at temperatures between thirty-two (32) and one hundred fifty (150) degrees F (0 and 65°C). Admittance of grease, oils, wax or fats to any extent into the sewer system shall be conditioned on the user supplying an inspection manhole satisfactory to the superintendent, downstream from the user's building drain, grease traps or other collectors.
   3. Any garbage that has not been properly shredded. The installation and operation of any garbage grinder equipped with a motor of three-fourths (3/4) horsepower (0.76 hp metric) or greater shall be subject to the review and approval of the superintendent.
   4. Any waters or wastes containing strong acid iron pickling wastes, or concentrated plating solutions, whether neutralized or not.
   5. Any waters or wastes containing objectionable or toxic substances; or wastes exerting an excessive chlorine requirement to such degree that any such materials received in the composite sewage treatment works exceed the limits established by the superintendent and/or the Division of Sanitary Engineering, and Tennessee Department of Health, for such materials.
   6. Any waters or wastes containing phenols or other taste or odor producing substances, in such concentrations exceeding limits which may be established by the superintendent as necessary, after treatment of the composite sewage, to meet the requirements of state, federal, and other public agencies of jurisdiction for such discharge to the receiving waters.
   7. Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the superintendent in compliance with applicable state or federal regulations.
   8. Any waters or wastes having a pH in excess of 9.0.
   9. Materials which exert or cause:
      1. Unusual concentrations of inert suspended solids (such as, but not limited to, Fullers earth, lime slurries, and lime residues) or of dissolved solids (such as, but not limited to, sodium chloride and sodium sulfate.)
      2. Excessive discoloration (such as, but not limited to, dye wastes and vegetable tanning solutions).
      3. Unusual Biochemical Oxygen Demand, or chlorine requirement in such quantities as to constitute a significant load on the sewage treatment works.
      4. Unusual volume of flow or concentration of wastes constituting "slugs" and defined herein.
   10. Waters or wastes containing substances which are not amenable to treatment or reduction by the sewage treatment processes employed, or are amenable to treatment only to such degree that the sewage treatment plant effluent cannot meet the requirements of other agencies having jurisdiction over discharge to the receiving waters.
   11. Any waters or wastes exceeding the following standards:
   12. The admission of any incompatible wastes listed in Table I shall not be admitted to any degree into the sewer system without first obtaining the consent of the superintendent. The superintendent shall first determine the daily average maximum concentration (mg/l) and instantaneous maximum concentration (mg/l) of the listed incompatible wastes, as well as any other toxic or hazardous materials that a user may discharge into the sewer system. The values listed are the maximum that may be admitted and approved by the superintendent to admit said incompatible, toxic or hazardous wastes shall be conditioned on the user supplying an approved inspection manhole downstream from the user's building drain, grease trap or other collection device. The object of these requirements is to enable the city to verify quality and quantity of discharges into the sewer system. The superintendent shall refer to appropriate Tennessee State Department of Health regulations to determine whether the toxidity or hazardous qualities, as well as the maximum strengths, of any wastewaters are admissible into the sewer system.
