Unusual volume of flow or concentration of wastes constituting slugs as defined herein.
9. 
Waters or wastes containing substances which are not amenable to treatment or reduction by the sewage treatment plant 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, such as NPDES permit requirements.
10. 
Any wastewater containing petroleum oil, non-biodegradable cutting oil or products of mineral oil origin in amounts that will cause interference or pass through.
11.

1. 
Reject the wastes, or
2. 
Require, at the owner's expense, pretreatment facilities to reduce objectionable characteristics or constituents to within the maximum limits provided for in Subsection (D) of this Section and/or Federal or State pretreatment standards, and/or

All businesses or activities where oils, greases or fats are cleaned from eating and food preparation utensils and equipment shall be required to install a grease separator before the discharge enters the City's sanitary sewer system. Any business or activity that produces discharge containing sand or similar materials must have a separator or interceptor installed. Such separators shall not be required for dwellings or private living quarters.
2. 
All required interceptors/separators shall have a sampling tee or manhole installed on the discharge side of a design to be submitted by the engineer or contractor and approved by the Director of Public Works.

7. 
For non-food-preparation establishments such as commercial repair garages, car washes, bottling plants, laundries and slaughterhouses that produce discharge containing oils, dissolved greases, sand or other heavy solid waste shall install appropriate interceptors in accordance with the International Plumbing Code as adopted by the City of Mount Vernon.
8. 
Where a food service establishment can document to the satisfaction of the City's Public Works Department that all food preparation occurs off premises or in establishments such as a church, senior center, or other similar organizations where food preparation does not exceed but once per month, the establishment shall install a grease separator in accordance with the International Plumbing Code currently adopted by the City and Subsection (H) of this Section. The minimum separator size shall be no less than seventy (70) pounds capacity.
G.

H. 
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 accessible 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.

All measurements, tests and analyses of the characteristics of water and wastes to which reference is made in this Article shall be determined in accordance with the latest edition of Standard Methods for the Examination of Water and Wastewater, published jointly by the American, Public Health Association, the American Water Works Association and the Water Pollution Control Federation 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 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-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-hour composites of all outfalls whereas pHs are determined from periodic grab samples.)
J. 
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, therefor, by the industrial concern.

Any State requirements and limitations on discharges shall apply to any case where they are more stringent than Federal requirements and limitations. Any facilities required to pretreat wastewater to a level acceptable to the City shall be provided, operated and maintained at the user's expense. Detailed plans showing the pretreatment facilities and operating procedures shall be submitted to the City for review and shall be acceptable to the City before construction of the facility. The review of such plans and operating procedures will in no way relieve the user from the responsibility of modifying the facility as necessary to produce an effluent meeting Federal categorical pretreatment standards. Any subsequent changes in the pretreatment facilities or method of operation shall be reported to and be acceptable to the City prior to the user's initiation of the changes.
[R.O. 2004 § 710.070; Ord. No. 2.48 § 7, 12-8-1992]
