A. 
No person shall discharge or cause to be discharged any stormwater, surface water, groundwater, roof runoff or subsurface drainage to any public sanitary sewer.
B. 
Stormwater, groundwater and all other unpolluted drainage shall be discharged to such sewers as are specifically designated as storm sewers or drainage ditches. Discharge of cooling water or process water to a natural outlet shall require approval of the Niagara County Health Department and a permit as required by the New York State Pollution Discharge Elimination System (SPDES) or other equivalent permit requirements.
C. 
The Village shall cause users' properties to be inspected at the time of any sale or transfer of real property and shall require permanent removal of any such private stormwater, surface water, groundwater, roof runoff or subsurface drainage connections to the Village of Middleport wastewater collection system.
[Added 5-16-2022 by L.L. No. 2-2022]
A. 
Grease, oil or grit traps shall be provided when, in the opinion of the Superintendent, they are necessary for the handling of liquids containing greases or any flammable wastes or grits; except that such traps shall not be required for a single-family detached dwelling unit. All traps shall be of a type and capacity approved by the Superintendent, and shall be located to be readily and easily accessible for cleaning and inspection. Grease and oil traps shall be constructed of impervious materials capable of withstanding abrupt and extreme changes in temperature. They shall be of substantial construction, watertight and equipped with easily removable covers which when secured in place shall be gastight and watertight.
B. 
Where required, all grease, oil and grit shall be installed and maintained by the owner at his expense.
A. 
Except where otherwise authorized pursuant to § 150-25 of this Part 1, no person shall discharge or cause to be discharged into the sanitary sewers any waters or wastes, as measured at the point of discharge, which contain BOD greater than 250 mg/l; or more than 250 mg/l of suspended solids; or any quantity of substances having a peak flow greater than 2% of the average daily sewage flow of the Village.
B. 
Where necessary in the opinion of the Village, the owner shall provide, at his expense, such pretreatment as may be necessary to reduce the BOD and/or suspended solids to 250 mg/l, or to reduce objectionable characteristics or constituents to within limits provided for in this Part 1 or control the quantities and rates of discharge of such waters or wastes.
C. 
Plans, specifications and other pertinent information relating to the proposed pretreatment facilities shall be prepared and submitted to a professional engineer licensed in the State of New York, for approval of the Village, and no construction of such facilities shall be commenced until said approvals are obtained in writing and until approval is received from any federal or state agency having approving power.
D. 
Where pretreatment facilities are provided for any waters or wastes, they shall be operated and maintained continuously by the owner at his expense.
E. 
The Village may require the owner of any industry discharging industrial wastes or may require any other owner to install equipment to monitor instantaneous flow rates, volume of flow per day and to collect samples therefrom. The Village may require that a suitable manhole be constructed to house the required equipment. A parshall flume shall be required as the control section for flow and volume data. A continuous chart plotting instantaneous flow rate versus time and an eight-digit totalizer shall be provided. The flow sampler shall be flow-proportional refrigerated composite sampling. The Village may require the use of a twenty-four-hour discreet sampler where conditions dictate.
F. 
Industrial users shall provide with their permit application, as required in Article VII, information which describes their proposed waste in quantity and character. The industry shall provide constituent concentrations for all parameters as required by the Village. Waste concentrations shall be determined from composite samples taken over a sufficient period of time to develop a representative sample. Discreet samples may be required by the Village to determine maximum hourly concentrations of constituents. Flow data shall be taken over a sufficient period of time to develop a probability plot representative of the discharge of the industry. The collection of data shall be supervised by the Village or a duly authorized representative. Industrial users shall continue to submit to the Village periodic reports describing the quantity and character of the discharge. The interval of the report, the parameters to be tested for and the flow data required shall be noted in the applicant's approved permit.
All measurements, tests and analyses the characteristics of waters and wastes to which reference is made in Article V et seq. shall be determined in accordance with generally accepted engineering and chemical principles, as approved by the Superintendent, and shall be determined at the control manhole provided for in § 150-22E, or upon suitable samples taken at said control manhole. In the event that no special manhole has been constructed, 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.
To determine the sewage flow from any establishment, the Village may use one of the following methods:
A. 
The amount of water supplied to the premises by the Village or a private water company as shown upon the water meter if the premises are metered.
B. 
The number of gallons of sewage discharged, into the sewer system as determined by measurements taken with a wastewater flow meter.
C. 
A figure determined by the Village of any combination of the foregoing or by any other equitable method.
Notwithstanding §§ 150-22A and B, where the strength of sewage from a nondomestic user of the POTW system exceeds 250 mg/l of either BOD or suspended solids or other prohibited waste discharge, such wastes, in the sole discretion of the Village, may be permitted to be discharged to the POTW by the Village, if the Village can adequately treat such wastes. In all such cases, an added charge, as noted below, will be made against such establishment according to the strength of such wastes. The strength of such wastes shall be determined by appropriate sampling methods taken over a sufficient period of time to ensure a representative sample. At the discretion of the Superintendent, analysis of samples shall be made by an independent laboratory. The costs of this sampling and analysis shall be borne by the user, whether owner or lessee. Added charges shall be determined by the Village of Middleport. These charges shall be based upon the cost of operation, maintenance, depreciation, amortization plus sufficient coverage for the POTW, and may contain a surcharge to the user over and above the actual cost to the Village in an amount to be established by the Village. Nothing in this section shall be interpreted to require the Village to accept any such waste.
