[Adopted 12-8-1975 by Ord. No. 1624]
A. 
The discharge of water or wastes into the sewerage system shall have prior approval by the Board of Commissioners if:
(1) 
The five-day twenty-degree-Celsius BOD is greater than 300 parts per million.
(2) 
The suspended solids content is greater than 350 parts per million.
(3) 
The chlorine demand is greater than 15 parts per million.
(4) 
The average daily flow is greater than 400 gallons per day.
(5) 
The content is of a toxic or nonbiodegradable substance.
(6) 
The wastes are considered by the Commissioners to offer possibilities of harm to any of its sewerage facilities.
B. 
Wastes described by one or more of the above characteristics shall be referred to herein as "industrial wastes."[1]

Editor's Note: Original Sections 1 and 2, which immediately preceded this section and dealt with sewer rates, were superseded by the current annual Sewer Rental Ordinance.
[Amended 1-12-1976 by Ord. No. 1629]
All existing industrial establishments which, upon the date of adoption of these rules and regulations, are discharging industrial wastes to the sewerage system shall, upon request by the Board of Commissioners, file, within three weeks, a questionnaire supplied by the Township, which shall furnish all pertinent data, including quantity of flow and an analysis of the water discharged to the sewerage system. The Board of Commissioners may, at its discretion, require regular self-inspections and analysis by the user.
A. 
New users. New establishments shall not begin to discharge any industrial waste into the system until the establishment has first submitted a written application to the Board of Commissioners for permission to do so and accompanied same with a detailed report prepared by a registered professional engineer acceptable to the Board. The report must set forth a complete analysis of quantities, loading the characteristics, present and future, in conformance with the provisions of this article.
B. 
Existing users. Existing establishments which are already connected may continue to discharge without an immediate detailed report to the Board of Commissioners. However, the Board may, in the future, require that those industries furnish a detailed report prepared by a registered professional engineer acceptable to the Authority. The report must set forth a complete analysis of quantities, loading and characteristics, present and future, in conformance with the provisions of this article.
C. 
Right of refusal. The Board of Commissioners reserves the right to refuse any industrial waste or discharge, to require pretreatment facilities or to compel discontinuance of the use of Township facilities. Should the Board decide to accept such industrial wastes, they will be accepted only after satisfactory agreements have been entered into between the Board and the industrial user, which may provide for the pretreatment of such industrial wastes by the industrial establishment to prevent the discharge of wastes deemed to be harmful to the system.
A. 
Analysis method. Analysis shall be made by using the laboratory methods for the examination of industrial waste as set forth in the latest edition of Standard Methods for Examination of Water and Sewage, as published by the American Public Health Association. Samples collected shall be of the twenty-four-hour composite-type, collected over a three-day period.
B. 
Manholes. Any user discharging industrial or industrial and domestic wastes into the sewerage system shall construct and maintain, at its expense, suitable control manholes to allow measurement and sampling of their wastes. These manholes shall be approved by and be accessible to authorized representatives of the Township.
C. 
Pretreatment. If required in the opinion of the Board of Commissioners, the user shall provide, at his expense, whatever pretreatment may be necessary to bring the waste being discharged within the limits set forth in these rules and regulations.
D. 
Flow measurement. If required in the opinion of the Board of Commissioners, the discharger of industrial wastes shall install a suitable device for continuously indicating, recording and totaling the flow discharged to the sewer system. All measuring devices and related facilities shall be approved by and be under the control of the Board of Commissioners. The discharger shall install and maintain such facilities at his own expense.
A. 
If the nature of the industrial waste received from any user imposes a burden on the Township facilities or if treatment of same results in an increase to the Township in the cost of operating and maintaining the system, the Board of Commissioners will impose an additional service charge, hereinafter called the "surcharge," upon the user. Said charges shall be collected in addition to and by the same means as the regular sewer rents set forth under Article II of this chapter and shall be subject to the same penalties. The charges shall also be subject to an annual review by the same means as and at the same time as regular sewer rents.
[Amended 1-12-1976 by Ord. No. 1629]
B. 
BOD provision. if an industrial waste is found to have a BOD in excess of 300 parts per million, the discharge of said waste shall be surcharged an amount equal to the product obtained by multiplying the actual volume of waste discharged in thousand gallons by the BOD surcharge rate. The BOD surcharge rate shall be determined by the following formula:
[Amended 6-30-1986 by Ord. No. 1960]
RBOD
=
0.00834 A (B-300)- + K
Where
RBOD
=
The BOD surcharge rate in cents per 1,000 gallons of waste discharged.
0.00834
=
Constant to convert parts per million to pounds per 1,000 gallons.
A
=
The average annual fixed operating and maintenance cost of treatment processes per pound of BOD received at the treatment plant.
B
=
The average BOD of the industrial waste expressed in parts per million as determined in accordance with this article.[1]
300
=
The maximum BOD permissible without surcharge.
K
=
Constant, in dollars, equal to engineering, legal and administrative costs incurred in determining surcharge.

Editor's Note: Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. I.)
C. 
Suspended solids provision. If an industrial waste is found to have an average suspended solids concentration in excess of 350 parts per million, the producer of said waste shall be surcharged an amount equal to the product obtained by multiplying the actual volume of waste discharged in thousand gallons by the suspended solids surcharge rate. The suspended solids surcharge rate shall be determined by the following formula:
Rss
=
0.00834 C (S-350) + K
Where
Rss
=
The suspended solids surcharge rate in cents per 1,000 gallons of waste discharged.
0.00834
=
Constant to convert parts per million to pounds per 1,000 gallons.
C
=
The average annual fixed operating and maintenance costs of the sludge digestion, drying and disposal operations per pound of suspended solids received at the treatment plant.
S
=
The average suspended solids concentration of the industrial waste expressed in parts per million as determined in accordance with this article or generally accepted standards in industry.
[Amended 6-30-1986 by Ord. No. 1960]
350
=
The maximum suspended solids concentration permissible without surcharge.
K
=
Constant, in dollars, equal to engineering, legal and administrative costs incurred in determining surcharge.
D. 
Provision for other characteristics. Upon the issuance of any permit for the discharge of industrial waste requiring treatment of characteristics other than BOD and suspended solids, the Board of Commissioners shall establish the rent to be paid for the use permitted thereunder, and upon approval by the Board, such rent shall be deemed imposed under this article.
