No person shall discharge or cause to be discharged any of the following-described waters or wastes to any public sewers:

(1)

Any liquid or vapor having a temperature higher than 150° F. 65° C. or in such quantities that the temperature at the treatment works influent exceeds 104° F. 40° C.

(2)

Any waters or wastes which contain grease or oil or other substance that will solidify or become discernibly viscous at temperatures between 32° and 150° F.

(3)

Any waters or wastes containing emulsified oil and grease exceeding an average of 50 parts per million [417 pounds per million gallons] ether soluble matter.

(4)

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. 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 5% nor any single reading over 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, ketones, aldehydes, peroxides, chlorates, perchlorates, bromates, carbides, hydrides and sulfides and any other substances which the town, the state or EPA has notified the user is a fire hazard or a hazard to the system.

(5)

Any noxious or malodorous gas, such as hydrogen sulfide, sulfur dioxide or nitrous oxide, or other substance which, either singly or by interaction with other wastes, is capable of creating a public nuisance or hazard to life or of preventing entry into sewers for their maintenance and repair.

(6)

Any garbage that has not been properly pulverized or ground to fine powder.

(7)

Any ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastic, wood, paunch manure, hair and fleshings, entrails, lime slurry, lime residues, beer and distillery slops, chemical residues, paint residues, cannery waste, bulk solids or any other solid or viscous substance capable of causing obstruction to the flow of the sewers or other interference with the proper operations of the sewerage system.

(8)

Any waters or wastes, acid and alkaline in reaction having corrosive properties capable of causing damage or hazard to structures, equipment and personnel of the sewerage system. Free acids and alkalies must be neutralized, at all times, within a permissible pH range of 6.0 to 9.5.

(9)

Any cyanides in excess of two parts per million by weight as CN.

(10)

Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by applicable local, state or federal regulations.

(11)

Any waters or wastes that, for a duration of 15 minutes, have a concentration greater than five times the average of that of normal sanitary sewage as measured by suspended solids and BOD and/or which are discharged continuously at a rate exceeding 1,000 gallons per minute except by special permit.

(12)

Any stormwater, cistern or tank overflow, cellar drain, discharge from any vehicle wash rack or water motor or the contents of any privy vault, septic tank or cesspool or the discharge of effluent from any air-conditioning machine or refrigeration unit.
