The Village shall receive and treat all industrial wastes except as stipulated under Section 925.02. In order to provide for equality among the users of the sewerage system, the acceptable wastes shall be evaluated in terms of both quantity and quality.
(a) Quantity. The quantity shall be measured volume of waste water expressed in gallons or cubic feet. All new and existing industrial waste connections shall be provided by the owner and the sampling and measuring facilities at the discretion of the Village or the owner shall provide derived volumes of wastes in a manner which reflects accuracy satisfactory to the Village.
(b) Quality; Surcharge.
(1) When either or both the total suspended solids and B.O.D. of acceptable wastes or waste water exceeds the values ascribed to normal waste waters, the excess concentration of either or both, as the case may be, shall be evaluated volumetrically in terms of normal waste and be subject to surcharge on the derived volume in accordance with the following formula:
Sv= (Sw-2800) x 0.90 x F x 133.690 + (Bw-1700) x 0.90 x F x 133.690
2900 1700
which reduced to its simplest form is:
Sv = F (Sw-2800) 43 + (B2-1700) 71
Sv: The derived volume of wastes subject to surcharge expressed in cubic feet.
Sw: The pounds per million gallons in the waste as discharged denoting suspended solids.
Bw: The pounds per million gallons of the waste as discharged denoting B.O.D.
0.90: Factor allowance for ninety percent degree of removals.
F: The flow expressed in millions of gallons of the wastes as discharged.
133,690: Factor to convert millions of gallons to an equivalent in cubic feet.
(2) The equivalent volume of normal waste water as derived from the excess above normal strength of any water and wastes shall be subject to a surcharge for the volume of equivalent normal waste water as computed from the formula, at a flat rate for each 100 cubic feet, as previously computed. This rate shall be the prevailing minimum rate on a volume basis, as provided for in Ordinance No. 1068.
(3) The surcharge is in addition to the present fixed charges for normal wastewater.
(c) Pretreatment. The Village shall have the right to require pretreatment of waste when in its opinion the same is necessary to meet permit requirements and to protect the integrity of its system. (Ord. 97-23. Passed 8-11-97.)
(d) Grease, Sand and Oil Traps. Grease, oil and sand interceptors shall be provided when in the opinion of the Utilities Director or Wastewater Treatment Plant Superintendent, they are necessary for proper handling of liquid wastes containing floating grease or oil in excessive amounts, or any flammable wastes, sand or other harmful ingredients. (A trap for the interception of grease, oil and mud shall be provided on a connection from a restaurant, club, hotel, residential dwelling consisting of more than 4 units, food, or bakery establishment, commercial or institutional kitchen, public garage, automobile washing station, slaughter or packing house.) The Utilities Board may grant exemption from the street application of this provision upon application and for good cause shown.
All interceptors shall be of a type and capacity approved by the Utilities Director or Wastewater Treatment Plant Superintendent, and shall be located as to be readily and easily accessible for cleaning and inspections. All interceptors 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 bolted in place shall be gas tight and watertight. Where installed, all grease, oil and sand interceptors shall be maintained by the owner(s) at the owner(s)’ expense, in continuous efficient operation at all times.
In the maintenance of these interceptors, the owner(s) shall be responsible for the proper removal and disposal of appropriate means of the captured material and shall maintain records of the dates and means of disposal, which shall be subject to review by the Utilities Director or Wastewater Treatment Plant Superintendent. Any removal and hauling of the collected material must be performed by currently licensed waste disposal firms unless approved otherwise by the Utilities Director or Wastewater Treatment Plant Superintendent.
Where the potential for the discharge of flammable substances exists, the user may be required to install and maintain an approved combustible gas detention meter.

(e) Amalgam Management at Dental Offices.
(1) This section applies to any dental office that places or removes amalgam. If work in a dental office is limited to work that does not involve placing or removing amalgam, such as orthodontics, periodontics, oral and maxillo-facial surgery, endodontics or prosthodontics, then this section does not apply.
(2) All dental offices shall implement best management practices for amalgam as established by the American Dental Association by July 5, 2005.

(Ord. 04-27. Passed 12-13-04.)
(f) Control Manhole. If so ordered by the Village, the owner or operator of any premises or facility discharging industrial wastes into the system shall install at his own cost and expense, suitable monitoring equipment to facilitate the accurate observation, sampling and measurement of wastes. Such equipment shall be maintained in proper working order and kept safe and accessible at all times.
The monitoring equipment shall be located and maintained on the industrial user’s premises outside of the building. When such a location would be impractical or cause undue hardship on the user, the Village may allow such a facility to be constructed in the public right of way, and located so that it will not be obstructed by public utilities, landscaping or parked vehicles.
(g) Industrial Permit Reports. All industrial users who discharge or propose to discharge wastewater to the wastewater treatment system shall maintain such records of production and related factors, effluent flow, and pollutant amounts and concentrations of such pollutants that are necessary to demonstrate compliance with the requirements of this chapter and any applicable State or Federal pretreatment standards or requirements.
Such records shall be made available upon request by the Village. All such records relating to compliance with pretreatment standards shall be made available to officials of the EPA upon demand.
(h) Notification Procedures. Each industrial user shall provide protection from accidental discharge of prohibited materials or other wastes regulated by this chapter. Facilities to prevent accidental discharge of prohibited materials shall be provided and maintained at the owner’s or operator’s own cost and expense. Detailed plans showing facilities and operating procedures to provide this protection shall be submitted to the Village for review, and shall be approved by the Village before construction of the facility. Review and approval of such plans and operating procedures shall not relieve the industrial user from the responsibility to modify his facility as necessary to meet the requirements of this chapter.
If, for any reason, a facility does not comply with or will be unable to comply with any prohibition or limitations in this chapter, the facility responsible for such discharge shall immediately notify the Village so that corrective action may be taken to protect the treatment system. In addition, a written report addressed to the Village detailing the date, time and cause of the accidental discharge; the quantity and characteristics of the discharge; and the corrective action taken to prevent future discharges, shall be filed by the responsible industrial facility within five days of the occurrence of the noncomplying discharge.
(i) Annual Audit/Review and Notification. The sewer service charge and user charges shall be reviewed annually by the Village in order to determine whether or not they are sufficient to defray the fixed charges, amortization costs, and annual cost of OM&R of the sewerage system. If the difference between the total annual revenue derived and total annual cost is sufficient to justify an increase or decrease in the sewer service charge or user charges, the Village will adjust the rates as required. The purpose of the annual review is also to maintain a proportional user charge.
Each user to be notified at least annually, in conjunction with a regular bill, of the rate and that portion of the sewer service charge which is attributable to OM&R costs of wastewater treatment services.
