   Persons proposing to or who actually discharge industrial wastes which contain none of the prohibited ingredients or characteristics set forth in §§ 51.110 through 51.118 of this code, other than excessive concentrations of BOD5, suspended solids and grease, hydrogen sulfide or ammonia shall be required to pretreat their wastes to meet the requirements of normal strength wastewater with the exception that wastes may be accepted for treatment if all the following requirements are met:

   (A)   The wastes will not cause damage to the sanitary sewer system;

   (B)   The wastes will not impair the wastewater treatment process; and

   (C)   The discharger of the waste agrees to pay a surcharge over and above the published sewer rates when the waste strength exceeds that of normal strength wastewater.

(Prior Code, § 51.131) Penalty, see § 51.999

§ 51.132 PRETREATMENT REQUIREMENTS.

   (A)   When the City Engineer or Director of Public Works determines that any industrial waste will be harmful to the structures, treatment processes or operation of the wastewater treatment works, or detrimental to the wastewater treatment facility effluent, the person discharging the waste shall provide, at the person’s own expense, preliminary treatment or processing facilities as may be determined by the Director of Public Works as necessary to make the waste acceptable for admission to the public sanitary sewers.

   (B)   When the City Engineer or Director of Public Works determines that an industrial waste must be pretreated, the owner shall submit plans and specifications of the proposed pretreatment facilities to the City Engineer or Director of Public Works for review. After the plans and specifications are reviewed as approved, the owner shall proceed to provide pretreatment facilities. If the pretreatment facilities are completed according to the plans and specifications, and the owner provides a proper sewer connection permit from the plant to the sanitary sewers, the Nebraska Department of Environment and Energy will issue the owner an industrial waste discharge permit authorizing such connection and permitting the owner to discharge waste into the sanitary sewers at the rate and in the quantity stated in the permit. The owner, at the owner’s expense, shall maintain these pretreatment facilities continuously in satisfactory and effective operation.
