G. 
Installation – Means of Measurement. The Director shall determine what commercial businesses and industries should be required to install an approved means of measurement, including but not limited to an improved flume or an automatic recording device.

2. 
In the event of a failure of payment of the user charge as provided herein for properties located outside of the City limits, the Director is authorized and directed to disconnect such property from the POTW.
F. 
Disposition of Moneys Received – Sewer Enterprise Fund. The funds received from the collection of the charges or rentals authorized by this chapter shall be deposited with the City Treasurer and shall be accounted for and be known as the "Sewer Enterprise Fund," and when appropriated by the City Council shall be available for the payment of the interest on any or all sewer bonds issued and outstanding or which may be issued for the sanitary and sewage facilities and to retire such bonds when any become due and the payment of the cost and expenses of acquisition, construction, maintenance, and repair of the City sewage system, treatment and disposal works and extensions and improvements thereto.

A. 
General Prohibitions. No user shall introduce or cause to be introduced into the POTW any pollutant or wastewater which causes pass through or interference. These general prohibitions apply to all users of the POTW whether or not they are subject to categorical pretreatment standards or any other national, State, or local pretreatment standards or requirements.
B. 
Specific Prohibitions. No user shall introduce or cause to be introduced into the POTW the following pollutants, substances, or wastewater:
1. 
Pollutants which create a fire or explosive hazard in the POTW, including, but not limited to, wastestreams with a closed-cup flashpoint of less than one hundred forty (140) degrees Fahrenheit (sixty (60) degrees Celsius) using the test methods specified in 40 CFR § 261.21;
2. 
Wastewater having a pH less than 5.5 or more than 9.0, or otherwise causing corrosive structural damage to the POTW or equipment;
3. 
Solid or viscous substances in amounts which will cause obstruction of the flow in the POTW resulting in interference but in no case solids greater than one-half (0.5) inch or one and twenty-seven hundredths (1.27) centimeters in any dimension;
4. 
Pollutants, including oxygen-demanding pollutants (BOD, etc.), released in a discharge at a flow rate and/or pollutant concentration which, either singly or by interaction with other pollutants, will cause interference with the POTW;
5. 
Wastewater having a temperature greater than one hundred five (105) degrees Fahrenheit (forty (40) degrees Celsius), or which will inhibit biological activity in the treatment plant resulting in interference;
6. 
Petroleum oil, nonbiodegradable cutting oil, or products of mineral oil origin, in amounts that will cause interference or pass through;
7. 
Pollutants which result in the presence of toxic gases, vapors, or fumes within the POTW in a quantity that may cause acute worker health and safety problems;
8. 
Trucked or hauled pollutants including septic tank waste;
9. 
Noxious or malodorous liquids, gases, solids, or other wastewater which, either singly or by interaction with other wastes, is sufficient to create a public nuisance or a hazard to life, or to prevent entry into the sewers for maintenance or repair;
10. 
Wastewater which imparts color which cannot be removed by the treatment process, such as, but not limited to, dye wastes and vegetable tanning solutions, which consequently imparts color to the treatment plant's effluent;
11. 
Wastewater containing any radioactive wastes or isotopes except in compliance with applicable State or Federal regulations;
12. 
Storm water, surface water, groundwater, artesian well water, roof runoff, street drainage, yard drainage, subsurface drainage, swimming pool drainage, condensate, deionized water, noncontact cooling water, and unpolluted wastewater, unless specifically authorized by the Director;
13. 
Sludges, screenings, or other residues from the pretreatment of industrial wastes;
14. 
Medical wastes, except as specifically authorized by the Director in a wastewater discharge permit;
15. 
Wastewater causing, alone or in conjunction with other sources, the treatment plant's effluent to be considered toxic to plant or animal life;
16. 
Detergents, surface-active agents, or other substances which may cause excessive foaming in the POTW;
17. 
Fats, oils, or greases of animal or vegetable origin in concentrations greater than 100 milligrams per liter (100 mg/l), except as specifically authorized by the Director in the wastewater discharge permit;
18. 
Wastewater causing two (2) readings on an explosion hazard meter at the point of discharge into the POTW, or at any point in the POTW, of more than five percent (5%) or any single reading over ten percent (10%) of the lower explosive limit of the meter.
Pollutants, substances, or wastewater prohibited by this section shall not be processed or stored in such a manner that they could be discharged to the POTW.
(Ord. 12-004)
A. 
The local limits listed in subsection B of this section are established to prevent pass through, interference, and short-circuiting at the wastewater treatment plant; and to protect against detrimental impacts to the environment, including the natural groundwater resource, in the vicinity of the wastewater treatment plant. No person shall discharge wastewater containing in excess of these local limits, unless specifically authorized by the Director, or his/her authorized designee, in the wastewater discharge permit.
The local limits listed in subsection B of this section apply at the point where the wastewater is discharged into the publicly owned wastewater collection system. The concentration based on local limits listed in subsection B of this section shall be instantaneous peak limits, unless specifically stated otherwise. All concentration-based local limits for metallic substances are for "total" metal, unless indicated otherwise, and are the maximum allowable for any given sample.
