[R.O. 2017 § 700.210; Ord. No. 04-40 § 3-1, 10-19-2004]
No person shall discharge anything other than wastewater to the POTW. Any connection, drain or arrangement which will permit any other water to enter the POTW shall be deemed to be a violation of this Chapter.
[R.O. 2017 § 700.220; Ord. No. 04-40 § 3-2, 10-19-2004]
A. 
These general restrictions apply to all users of the POTW whether or not the user is subject to National Categorical Pretreatment Standards or any other National, State or local pretreatment standards or requirements.
B. 
No person shall contribute or cause to be contributed, directly or indirectly, any pollutant or wastewater which acting alone or in conjunction with other substances present in the POTW interferes with the operation or performance of the POTW or which causes or contributes to interference or pass-through. A person shall not contribute substances to the POTW which may:
1. 
Create a fire or explosion hazard including, but not limited to, gasoline, benzene, naphtha, fuel oil or other flammable or explosive liquids, solids or gases with a closed cup flash point of less than one hundred forty degrees Fahrenheit (140° F.) [sixty degrees Celsius (60° C.)] (the RCRA ignitability standard for liquid characteristic waste) using the test methods specified in 40 CFR 261.21. At no time shall two (2) successive readings over a one-hour period on any explosion hazard meter, at the point of discharge into the POTW, or at any point in the POTW, be more than five percent (5%) nor shall any single reading be over ten percent (10%) of the lower explosive limit (LEL).
2. 
Cause corrosive damage or hazard to structures, equipment or personnel of the POTW. In no case shall the discharges have a pH lower than five point zero (5.0) or higher than twelve point five (12.5).
3. 
Cause obstruction to the flow in the POTW or other interference with the operation of the wastewater facilities due to accumulation of solid or viscous material such as, but not limited to, grease, garbage with particles greater than one-half (1/2) inch in any dimensions, animal tissues, paunch manure, bones, hair, hides or fleshings, entrails, blood, feathers, ashes, cinders, sand, spent lime, stone or marble dust, metal, glass, straw, shavings, rags, plastics, tar, asphalt, residues from refining or processing of fuel or lubricating oil, mud or glass grinding or polishing wastes.
4. 
Constitute a rate of discharge sufficient to cause interference with the operation and performance of POTW.
5. 
Contain heat in amounts which will inhibit biological activity of the POTW treatment plant. In no case shall the temperature of the point of connection to the POTW exceed one hundred fifty degrees Fahrenheit (150° F.) [sixty-five degrees Celsius (65° C.)] or cause the temperature at the treatment plant influent to exceed one hundred four degrees Fahrenheit (104° F.) [forty degrees Celsius (40° C.)].
6. 
Contain any garbage that has not been properly shredded.
7. 
Contain petroleum oil, non-biodegradable cutting oil or products of mineral oil origin in amounts that will cause interference or pass-through.
8. 
Contain any noxious or malodorous liquids, gases or solids which either singly or by intersection with other wastes are sufficient to create a public nuisance or hazard to life and property or that result in toxic gases, vapors and fumes in a quantity that may cause acute worker health and safety problems.
9. 
Contain radioactive waste or isotopes of such half-life or concentration as may exceed limits defined by applicable State and Federal regulations.
10. 
Contain any odor- or color-producing substances exceeding concentration limits which may be established by the Director of Public Works for the purpose of meeting the POTW's NPDES permit.
11. 
Contain any substances which may cause the POTW's effluent or any product of the POTW, such as residues, sludges or scums, to be unsuitable for reclamation and reuse or interfere with the reclamation process where the POTW is pursuing a reuse and reclamation program.
12. 
Contain toxic pollutants in sufficient quantity to injure or interfere with the wastewater treatment process, constitute a hazard to humans or other life forms, create a toxic effect in the receiving waters of the POTW, or exceed the limitation set forth in an applicable categorical pretreatment standard.
13. 
Contain compatible pollutants of such concentration, quantity or rate of discharge that the POTW treatment efficiency is impaired or unusual attention or expense is required to handle such materials in the POTW.
14. 
Contain fats, oils or grease of animal or vegetable origin greater than one hundred (100) milligrams per liter that will cause interference or pass-through.
15. 
Contain any trucked or hauled pollutants, except at points and times designated by the Director in accordance with Sections 700.170 and 700.180.
16. 
Contain any medical wastes, except as specifically authorized by the Director.
17. 
Contain pollutants, including oxygen demanding pollutants (BOD5, 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.
18. 
Contain stormwater, surface water, groundwater, well water, roof runoff, subsurface drainage, swimming pool drainage, condensate, deionized water, cooling water and unpolluted wastewater, unless specifically authorized by the Director.
19. 
Contain sludges, screenings or other residues from the pretreatment of industrial wastes.
20. 
Contain wastewater causing, alone or in conjunction with other sources, the treatment plant's effluent to fail a toxicity test.

[R.O. 2017 § 700.240; Ord. No. 04-40 § 3-4, 10-19-2004]
A. 
No user subject to an applicable Federal Categorical Pretreatment Standard or any other National, State or local pretreatment standard or requirement shall discharge or cause to be discharged to the POTW wastewater containing substances in excess of the quantity prescribed unless otherwise provided in this Section.
B. 
Upon application by a user, the Director may revise any limitations on substances specified in the applicable pretreatment standards to reflect removal of the substances by the wastewater treatment facility. EPA approval is required before removal credits may be granted by the Director. The revised discharge limit for specified substances shall be derived in accordance with 40 CFR 403.7 and 403.11.
C. 
Upon application by a user, the Director may adjust any limitations on substances specified in the applicable pretreatment standards to consider factors relating to such persons which are fundamentally different from the factors considered by EPA during the development of the pretreatment standards. Request for and determinations of a fundamentally different factor adjustment shall be in accordance with 40 CFR 403.13.
D. 
The Director shall notify any user affected by the provisions of this Section and shall establish an enforceable compliance schedule for each.
[R.O. 2017 § 700.250; Ord. No. 04-40 § 3-5, 10-19-2004]

[R.O. 2017 § 700.260; Ord. No. 04-40 § 3-6, 10-19-2004]
Nothing in this Chapter shall be construed as preventing any special agreement or arrangement between the City and any user of the POTW, whose wastewater discharge is not subject to State or Federal regulations, whereby wastewater of unusual strength or character is accepted into the system and specially treated subject to any payments or user charges as may be applicable.
[R.O. 2017 § 700.270; Ord. No. 04-40 § 3-7, 10-19-2004]
No user shall increase the use of process water or in any way attempt to dilute a discharge as a partial or complete substitute for adequate treatment to achieve compliance with the limitations contained in applicable standards or any other specific pollutant limitation developed by the City and State.
[R.O. 2017 § 700.280; Ord. No. 04-40 § 3-8, 10-19-2004]
A. 
The Director may require any industrial user to develop and implement an accidental discharge/ slug control plan. At least once every two (2) years the Director shall evaluate whether each significant industrial user needs such a plan. Any industrial user required to develop and implement an accidental discharge/slug control plan shall submit a plan which addresses, at a minimum, the following:
1. 
Description of discharge practices, including non-routine batch discharges.
2. 
Description of stored chemicals.
3. 
Procedures for immediately notifying the POTW of any accidental or slug discharge. Such notification must also be given for any discharge which would violate any of the restricted discharges in Section 700.220, with procedures for follow-up written notification within five (5) days.
4. 
Procedures to prevent adverse impact from any accidental or slug discharge. Such procedures include, but are not limited to, inspection and maintenance of storage areas, handling and transfer of material, loading and unloading operations, control of plant site runoff, worker training, building of containment structures or equipment, measures for containing toxic organic pollutants, including solvents, and/or measures and equipment for emergency responses.
[R.O. 2017 § 700.290; Ord. No. 04-40 § 3-9, 10-19-2004]
A. 
Any user who commences the discharge of hazardous waste shall notify the POTW, the EPA Regional Waste Management Division Director and State hazardous waste authorities, in writing, of any discharge into the POTW of a substance which, if otherwise disposed of, would be a hazardous waste under 40 CFR 261. Such notification must include the name of the hazardous waste as set forth in 40 CFR 261, the EPA hazardous waste number and the type of discharge (continuous, batch or other). If the user discharges more than one hundred (100) kilograms of such waste per calendar month to the POTW, the notification also shall contain the following information to the extent such information is known and readily available to the user: an identification of the hazardous constituents contained in the wastes, an estimation of the mass and concentration of such constituents in the waste stream discharged during that calendar month, and an estimation of the mass of constituents in the waste stream expected to be discharged during the following twelve (12) months. All notifications must take place no later than one hundred eighty (180) days after the discharge commences. Any notification under this Subsection needs to be submitted only once for each hazardous waste discharged. However, notifications of changed conditions must be submitted under Section 700.310. The notification requirement in this Section does not apply to pollutants already reported by users subject to categorical pretreatment standards under the self-monitoring requirements of Subsections (A), (C) and (D) of Section 700.310.
B. 
Dischargers are exempt from the requirements of Subsection (A) of this Section during a calendar month in which they discharge no more than fifteen (15) kilograms of hazardous wastes, unless the wastes are acute hazardous wastes as specified in 40 CFR 261.30(d) and 261.33(e). Discharge of more than fifteen (15) kilograms of non-acute hazardous wastes in a calendar month, or of any quantity of acute hazardous wastes as specified in 40 CFR 261.30(d) and 261.33(e), requires a one-time notification. Subsequent months during which the user discharges more than such quantities of any hazardous waste do not require additional notification.
C. 
In the case of a new regulations under Section 12001 of RCRA[1] identifying additional characteristics of hazardous waste or listing any additional substance as a hazardous waste, the user must notify the Director, the EPA Regional Waste Management Division Director and State hazardous waste authorities of the discharge of such substance within ninety (90) days of the effective date of such regulations.
[1]
Editor's Note: See 42 U.S.C. § 6901 et seq.
D. 
In the case of any notification made under this Section, the user shall certify that it has a program in place to reduce the volume and toxicity of hazardous wastes generated to the degree it has determined to be economically practical.
E. 
This Section does not create a right to discharge any substance not otherwise permitted to be discharged by this Chapter, a permit issued thereunder or any applicable Federal or State law.
[R.O. 2017 § 700.295; Ord. No. 05-28 §§ 1 — 7, 10-18-2005]
A. 
Purpose. This Section is intended to ensure to the extent possible that the operating cost of lift stations and force mains will not be subsidized by users of the sewer system who are outside the area served by the force main and lift station. Due to the higher operating costs and the environmental problems that can occur with the operation of lift stations and force mains, the City has determined that construction of such facilities should occur under the limited circumstances described in this Section.
B. 
Definitions. As used in this Section, the following terms shall have these prescribed meanings:
INCREMENTAL COST TO CONSTRUCT GRAVITY SEWERS
The cost per square foot, which needs to be collected so that after ten (10) years sufficient funds are available to build gravity sewers to replace the lift station and force main multiplied times the number of square feet served by the proposed lift station and force main.
TEN-YEAR FIXED COST
The cost to check and repair a lift station for a ten-year period.
TEN-YEAR VARIABLE COST
The average utility cost for a ten-year period per square foot times the number of square feet served by the proposed lift station and force main.
THE DIFFERENCE IN COST
The ten-year fixed cost plus the ten-year variable cost to operate the lift station and force main, plus the incremental cost to construct gravity sewers.
C. 
Apportionment Of Costs. If the City finds the cost to install a gravity sewer is less than the cost to install the lift station and force main plus the difference in cost, then the gravity sewer shall be constructed at the cost of the developer. If, however, the City finds the cost to install the gravity sewer is greater than the cost to install the lift station and force main plus the difference in cost, then the City may decide to pay the developer the difference and require the developer to install the gravity sewer. If the City decides not to pay the additional cost for installation of the gravity sewer, the City may allow the developer to install gravity sewers or install the lift station and force main. If the developer elects to install the lift station and force main, then the developer shall pay the City the difference in cost.
D. 
Connection To Existing Lift Stations. A request by a property owner or developer to connect a new development to a sewer system served by an existing lift station will be reviewed by the City on a case-by-case basis. The City will not allow a new development to connect to a lift station unless there is sufficient capacity in the lift station and force main to serve the additional property or unless the developer increases the capacity of the lift station and force main in an amount sufficient to serve the new property as determined by the City. If the City finds the costs to install a gravity sewer is less than the cost to expand the lift station and force main plus the ten-year variable cost and the incremental cost to construct gravity sewers, then the gravity sewer shall be constructed at the cost of the developer. If, however, the City finds the cost to install the gravity sewer is greater than the cost as computed above, then the City may decide to pay the developer the difference and require the developer to install the gravity sewer. If the City decides not to pay the additional cost for installation of the gravity sewer, the City may allow the developer to install gravity sewers or connect to an existing lift station and force main and expand said lift station and force main if necessary. If the developer elects to connect to the existing lift station and force main, then the developer shall pay the City the ten-year variable cost, plus the incremental cost to construct gravity sewers. These additional fees shall not be assessed for any existing subdivisions which are served by existing lift stations. Fees also shall not be assessed for existing subdivisions under development in phases where the lift station and force main now serving the subdivision were planned to serve all phases of the development. Nothing contained herein shall be construed to prohibit the City from entering into a contract with a developer which allows the developer to recover a reasonable portion of the developer's ten-year fixed cost from third parties who are developing outside the sewer district and want to connect to the lift station and force main.
E. 
Annual Statement Of Difference In Costs. If there is any increase in the costs, the Director of Public Works or the City's Engineer shall file an annual statement with the City Clerk of ten-year fixed costs, the ten-year variable cost and the incremental cost to construct gravity sewers before such costs are used to compute the difference in cost. A copy of the first annual statement has been filed with this Ordinance No. 05-28 in the City Clerk's Office. A public meeting shall be held by the Director of Public Works to discuss the proposed increases and to obtain input from the public. After the public hearing the Director of Public Works may file with the City Clerk the annual statement of difference in costs. Any increase in the annual statement of difference in costs shall not become effective until thirty (30) days after it has been filed with the City Clerk. In the event a member of the Board of Aldermen files a written objection with the City Clerk within thirty (30) days after the annual statement has been filed, then the new annual statement of difference in costs shall not become effective until after it has been approved by the Board of Aldermen.
F. 
Prohibition Against Certain Lift Stations. Notwithstanding any other provision of this Section to the contrary, lift stations will not be considered acceptable where overflows of raw sewage from the lift station would flow into environmentally sensitive areas such as sinkholes, losing streams, spring recharge areas, public water supplies or other environmentally sensitive areas, except where additional design and construction features of the lift station overcome environmental concerns to the satisfaction of the Director of Public Works.
G. 
If a developer is allowed by the City to expand the capacity of a lift station and this expansion requires the replacement by the developer of the existing emergency generator, or motors, or pumps or other equipment, upon the replacement of such equipment with the new equipment approved by the City, and the installation of the equipment at developer's expense and dedication of the equipment to the City, the developer may remove and retain any equipment which the developer has replaced, for developer's own use, "as is," without any warranties by the City, express or implied. Developer shall furnish satisfactory proof to the City of payment of all labor and materials in connection with the acquisition and installation of new equipment, and the removal of existing equipment.
