[Ord. No. 979 §§1 — 2, 4-2-2012]
No person shall discharge or cause to be discharged any storm water, surface water, ground water, roof runoff, subsurface drainage, including interior and exterior foundation drains, uncontaminated cooling water, or unpolluted industrial process waters to any sanitary sewer.
[Ord. No. 979 §§1 — 2, 4-2-2012]
Storm water and all other unpolluted drainage shall be discharged to such sewers as are specifically designated storm sewers or to a natural outlet approved by the Superintendent. Industrial cooling water or unpolluted process waters may be discharged on approval of the Superintendent. Industrial cooling water or unpolluted process waters may be discharged on approval of the Superintendent to a storm sewer or natural outlet.
[Ord. No. 979 §§1 — 2, 4-2-2012]
A. 
No person shall discharge or cause to be discharged any of the following described waters or wastes to any public sanitary sewers:
1. 
Any gasoline, benzene, naphtha, fuel oil or other flammable or explosive liquid, solid or gas.
2. 
Any waters or wastes containing toxic or poisonous solids, liquids or gases in sufficient quantity, either singly or by interaction with other wastes, to injure or interfere with any sewage treatment process, constitute a hazard to humans or animals, create a public nuisance, or create any hazard in the receiving waters of the sewage treatment plant including, but not limited to, cyanides in excess of two (2) milligrams per liter as CN in the wastes as discharged to the public sewer.
3. 
Any waters or wastes having a five (5) day biochemical oxygen demand greater than two hundred fifty (250) parts per million (1,000,000) by weight, or containing more than three hundred (300) parts per million (1,000,000) by weight of suspended solids, or having an average daily flow greater than two percent (2%) of the average sewage flow of the City shall be subject to the review of the Superintendent. Where necessary in the opinion of the Superintendent, the owner shall provide, at his expense, such preliminary treatment as may be necessary to reduce the biochemical oxygen demand to two hundred fifty (250) parts per million (1,000,000) by weight, or reduce the suspended solids to three hundred (300) parts per million (1,000,000) by weight, or control the quantities and rates of discharge of such waters or wastes. Plans, specifications and other pertinent information relating to proposed preliminary treatment facilities shall be submitted for the approval of the Superintendent and no construction of such facilities shall be commenced until such approvals are obtained in writing. A surcharge will be provided for excess BOD and suspended solids. The user charge established by the Board of Aldermen should be consulted.
4. 
Any waters or wastes having a pH lower than five and one-half (5.5) or having any other corrosive property capable of causing damage or hazard to structures, equipment and personnel of the sewage works.
5. 
Solids or viscous substances in quantities or of such size capable of causing obstruction to the flow in sewers, or other interference with the proper operation of the sewage works such as, but not limited to, ashes, cinders, sand, mud, straw, shavings, metal, glass, rags, feathers, tar, plastics, wood, unground garbage, whole blood, paunch manure, hair and fleshings, entrails and paper dishes, cups, mild containers, etc., either whole or ground by garbage grinders.
[Ord. No. 979 §§1 — 2, 4-2-2012]
A. 
No person shall discharge or cause to be discharged the following described substances, materials, waters or wastes if it appears likely in the opinion of the Superintendent that such wastes can harm either the sewers, sewage treatment process or equipment, have an adverse effect on the receiving stream, or can otherwise endanger life, limb, public property or constitute a nuisance. In forming his/her opinion as to the acceptability of these wastes, the Superintendent will give consideration to such factors as the quantities of subject wastes in relation to flows and velocities in the sewers, materials of construction of the sewers, nature of the sewage treatment process, capacity of the sewage treatment plant, and other pertinent factors. The substances prohibited are:
1. 
Any liquid or vapor having a temperature higher than one hundred fifty degrees Fahrenheit (150°F)(65°C).
2. 
Any water or wastes containing fats, wax, grease or oils, whether emulsified or not, in excess of fifty (50) milligrams per liter or containing substances which may solidify or become viscous at temperatures between thirty-two degrees Fahrenheit (32°F) and one hundred fifty degrees Fahrenheit (150°F) (0°C and 65°C).
3. 
Any garbage that has not been properly shredded. The installation and operation of any garbage grinder equipped with a motor of three-fourths (¾) horsepower (0.76 hp metric) or greater shall be subject to the review and approval of the Superintendent.
4. 
Any waters or wastes containing strong acid iron pickling wastes or concentrated plating solutions whether neutralized or not.
5. 
Any waters or wastes containing iron, chromium, copper, zinc, and similar objectionable or toxic substances; or wastes exerting an excessive chlorine requirement to such degree that any such material received in the composite sewage at the sewage treatment works exceeds the limits established by the Superintendent for such materials.
6. 
Any waters or wastes containing phenols or other taste- or odor-producing substances in such concentrations exceeding limits which may be established by the Superintendent as necessary, after treatment of the composite sewage, to meet the requirements of State, Federal, or other public agencies of jurisdiction for such discharge to the receiving waters.
7. 
Any radioactive wastes or isotopes of such half-life or concentration as may exceed limits established by the Superintendent in compliance with applicable State or Federal regulations.
8. 
Any waters or wastes having a pH in excess of nine and one-half (9.5).
9. 
Materials which exert or cause:
a. 
Unusual concentrations of inert suspended solids such as, but not limited to, Fuller's earth, lime slurries and lime residues or of dissolved solids such as, but not limited to, sodium chloride or sodium sulfate.
b. 
Excessive discoloration such as, but not limited to, dye wastes and vegetable tanning solutions.
c. 
Unusual BOD, chemical oxygen demand, or chlorine requirements in such quantities as to constitute a significant load on the sewage treatment works.
d. 
Unusual volume of flow or concentration of wastes constituting "slugs" as defined herein.
10. 
Waters or wastes containing substances which are not amenable to treatment or reduction by the sewage treatment processes employed or are amenable to treatment only to such degree that the sewage treatment plant effluent cannot meet the requirements of other agencies having jurisdiction over discharge to the receiving waters.
[Ord. No. 979 §§1 — 2, 4-2-2012]
A. 
If any waters or wastes are discharged or are proposed to be discharged to the public service, which waters contain the substances or possess the characteristics enumerated in Section 710.690 "Prohibited Substances" above and which in the judgment of the Superintendent may have a deleterious effect upon the sewage works, processes, equipment or receiving waters, or which otherwise create a hazard to life to constitute a public nuisance, the Superintendent may:
1. 
Reject the wastes;
2. 
By certified letter, detail the violation(s) observed by the Superintendent and notify the violator that he/she must meet with the Superintendent to review the alleged violations within ten (10) business days.
3. 
After such meeting, the violator shall be given sixty (60) calendar days for first (1st) violation or thirty (30) days for successive violations to develop and implement a plan to come into compliance with this Article. Such plan must also include a time frame within which compliance will be attained. The Superintendent may require such plan to include pretreatment of the waste to bring it to an acceptable level prior to discharge and/or control of the quantity or rate of discharge to the system. If, after the appropriate time period, the violator has not complied with this Subsection, the City will start to impose an excess processing fee as set forth in Subsection (4) below.
If the City feels that the violator is not making adequate attempts to resolve the problem, the City may make all processing fees and lab cost retroactive back to the date of the first (1st) notification as stated in Subsection (2) above.
4. 
From the time of the original notice until future compliance is attained, the Superintendent shall make weekly tests of the discharge in question. The violator shall be responsible for the fees associated with said tests. Furthermore, the violator shall be responsible for added cost of treatment of non-compliant wastes not already covered by existing taxes or sewer charges. Such fees shall be calculated using the following formula:
(A-B) MGD x (8.34 lbs.) x (C)=Daily Fine
A
=
Average monthly non-compliant test results measured as an average of weekly test
B
=
Maximum allowed discharge under prohibited substance
MGD
=
Million gallon day
8.34
=
Weight of one (1) gallon of water in pounds
C
=
Cost of processing a pound of the non-compliant discharge ($/lb.). The City will determine cost/lb.
5. 
Once the violator's discharge has met the required limits as set forth in Section 710.690 "Prohibited Substances", the violator will be required to be monitored weekly for an additional month, with the violator being responsible for all costs associated with the monitoring. Once the violator has reached and maintained discharge limits below those that are set forth in the Section 710.690 "Prohibited Substances", the City will review the finding and decide whether to drop the violator back to a random monitoring requirement, with the City covering the cost for these random monitoring tests.
If, during the random monitoring, the violator begins to exceed the limits as set forth in Section 710.690 "Prohibited Substances", the Superintendent shall notify the violator, by certified letter, that the City is placing the violator back on a weekly monitoring status, until at which time the violator's discharge meets the required limits as set forth in Section 710.690 "Prohibited Substance". The violator will be responsible for paying all cost and fines incurred during this monitoring.
6. 
If the Superintendent believes at any time that the violator is not acting in good faith, then the Superintendent reserves the right to reject any such discharge.
7. 
Any violator aggrieved by a decision of the Superintendent may appeal such a decision to the Board of Aldermen of the City of Concordia.
[Ord. No. 979 §§1 — 2, 4-2-2012]
Grease, oil and sand interceptors shall be provided when, in the opinion of the Superintendent, they are necessary for the proper handling of liquid wastes containing grease in excessive amounts, or any flammable wastes, sand or other harmful ingredients; except that such interceptors shall not be required for private living quarters or dwelling units. All interceptors shall be of a type and capacity approved by the Superintendent and shall be located as to be readily and easily accessible for cleaning and inspection.
[Ord. No. 979 §§1 — 2, 4-2-2012]
Where pre-treatment or flow-equalizing facilities are provided for any waters or wastes, they shall be maintained continuously in satisfactory and effective operation by the owner at his/her expense.
[Ord. No. 979 §§1 — 2, 4-2-2012]
When required by the Superintendent, the owner of any property serviced by a building sewer carrying industrial wastes shall install a suitable control manhole together with such necessary meters and other appurtenances in the building sewer to facilitate observation, sampling and measurement of the wastes. Such manhole, when required, shall be accessibly and safely located and shall be constructed in accordance with plans approved by the Superintendent. The manhole shall be installed by the owner at his/her expense and shall be maintained by him/her so as to be safe and accessible at all times.
[Ord. No. 979 §§1 — 2, 4-2-2012]
All measurements, tests and analyses of the characteristics of waters and wastes to which reference is made in this Chapter shall be determined in accordance with the latest edition of "Standard Methods for the Examination of Water and Wastewater" published by the American Public Health Association and shall be determined at the control manhole provided or upon suitable samples taken at said control manhole. In the event that no special manhole has been required, the control manhole shall be considered to be the nearest downstream manhole in the public sanitary sewer to the point at which the building sewer is connected. Sampling shall be carried out by customarily accepted methods to reflect the effect of constituents upon the sewage works and to determine the existence of hazards to life, limb and property. (The particular analyses involved will determine whether a twenty-four (24) hour composite of all outfalls of a premises is appropriate or whether a grab sample or samples should be taken. Normally, but not always, BOD and suspended solids analyses are obtained from twenty-four (24) hour composites of all outfalls whereas pHs are determined from periodic grab samples.)
[Ord. No. 979 §§1 — 2, 4-2-2012]
No statement contained in this Article shall be construed as preventing any special agreement or arrangement between the City and any industrial concern whereby an industrial waste of unusual strength or character may be accepted by the City for treatment, subject to payment therefore, by the industrial concern.
