9-1D-7: CONTROL MANHOLES AND TEST LOCATIONS:

When required by the public works supervisor, the owner of any property served by a building sewer carrying industrial wastes shall install a suitable control manhole or other suitable sampling point, with measuring and sampling devices included, in the building sewer to facilitate observation, sampling, and measurement of the waters or wastes. Such sampling point and appurtenances, when required, shall be readily accessible and safely located and shall be constructed in accordance with plans engineered and stamped by a licensed Montana professional engineer and approved by the public works supervisor. The sampling point and appurtenances shall be installed by the owner at his/her expense and shall be maintained by him/her so as to be readily and safely accessible at all times, with all equipment maintained in continuously satisfactory and accurate operational condition. (Ord. 04-01, 2-10-2004)

9-1D-8: WASTEWATER TESTING AND ANALYSES:

All measurements, tests and analyses of the characteristics of the waters and wastes to which reference is made in sections 9-1D-1 and 9-1D-4 of this article shall be determined in accordance with 40 CFR part B6, guidelines establishing test procedures for the analysis of pollutants, unless otherwise specified, and shall be determined at the sampling point provided for in section 9-1D-7 of this article upon suitable samples taken at such sampling point. In the event that no sampling point has been required, the sampling point shall be considered to be the nearest manhole downstream to a point in the public sanitary sewer at which the building sewer is connected. All sampling and testing will be done by an agency approved by the public works supervisor and at the expense of the owner of the property generating the need to sample. (Ord. 04-01, 2-10-2004)

9-1D-9: SEPTAGE DISPOSAL:

   A.   Prohibited Discharge: It is prohibited to discharge septage either directly or indirectly into any municipal wastewater system/storm sewer system, or any appurtenance thereof without paying a septage disposal fee and obtaining a septage disposal permit. Permitted septage disposal shall be performed at locations approved by the public works supervisor.

   B.   Permit: All septage haulers must obtain an annual permit issued by the city clerk's office. Proof of insurance must be provided before a permit will be issued. Both the city and the septage hauler will have copies of the permit. The annual fee for a permit, effective July 1 to June 30 of the following year, is on file with the city clerk.

   C.   Restrictions: Only domestic septic tank waste will be accepted.

   D.   Manifest: A manifest form must be completed for each load. It must be signed by the owner of the waste and the septage hauler and will be kept as a record by the city.

   E.   City Contact: Haulers must call the city office on the day they plan to dump. No dumping will be allowed unless supervised by a city employee. The employee will show the septage hauler where to dump.

   F.   Hours Of Operation: Dumping will be only allowed Monday through Friday, seven o'clock (7:00) A.M. to three o'clock (3:00) P.M., except holidays.

   G.   Waste: It is recommended the septage hauler thin his loads with water to keep from having the load rejected because it is thick and not fluid enough.

   H.   Discharge Limit: Reserved.

   I.   Prohibited Waste: No person or entity hauling wastewater shall discharge or cause to be discharged anything described as follows:

      1.   Pollutants that will create a fire or explosion hazard.

      2.   Pollutants that will cause corrosive structural damage.

      3.   Pollutants that are thick or will cause obstruction to flow.

      4.   Pollutants whose concentrations will interfere with the operation of the wastewater treatment plant (i.e., crude oil).

      5.   Agricultural waste.

      6.   Car wash holding tanks or sumps.

   J.   Observation, Sampling, And Testing: The city is empowered to observe and reject the waste or require testing to provide a laboratory analysis of the wastewater. The cost of analysis shall be paid for by either the generator or the hauler of the wastewater.

   K.   Rejected Waste: The city may refuse or decline to accept wastewater from any septage hauler it determines to be in violation of these regulations or any city code. The city may also reject any waste when there is any question of any detrimental effect to the wastewater treatment plant. Other actions may include:

      1.   Require pretreatment to an acceptable condition for discharge (i.e., dilution).

      2.   Require control over the quantities and rates of discharge.

   L.   Rates: Septage haulers shall pay rates appropriate for this special city service. Charges will be paid at the time of disposal. The disposal rates are on file with the city clerk. (Ord. 04-01, 2-10-2004)

9-1E-2: ACTIONS OF THE SUPERVISOR:

Whenever the public works supervisor determines that a significant industrial user is contributing to the municipal wastewater system any of the substances referred to in article D of this chapter in such amounts as to interfere with the operation of the municipal wastewater system or to constitute a harmful contribution to the municipal wastewater system, the public works supervisor shall:

   A.   Notify or cite the significant industrial user in accordance with section 9-1E-10 of this article and develop and apply specific effluent limitations and pretreatment requirements for the significant industrial user to correct the interference with or harm to the municipal wastewater system.
