In addition, an annual excess usage charge shall be computed on the previous calendar year's water usage as reported by the Borough of Park Ridge Water Department and the BCUA's current calendar year's equivalent rate per gallon of flow and billed in accordance with the procedures as set forth in § 81A-7H.
C. 
Threshold for imposition of excess usage charge.
(1)

To determine the annual excess user charges for all users, the charges are calculated based on the following formula:
Annual Excess User Charge = (Vu – 250,000 gallons) x Re
Where:
Vu
=
Previous calendar year's sewer usage (in gallons) calculated by the sum of the first and second quarter billed water consumption (in gallons) multiplied by two.

=
[Rf + (1.0 x Rbod x Cbod x 8.34) + (1.0 x Rtss x Ctss x 8.34)] / 1,000,000
Where:
Rf
=
Current year's annual BCUA flow rate for treatment of a unit of wastewater flow (rate/million gallons).
Rbod
=
Current year's annual BCUA BOD rate for treatment of a unit of BOD (rate/1,000 pounds).
Cbod
=
Average BCUA municipal BOD concentration in milligrams per liter.
Rtss
=
Current year's annual BCUA TSS rate for treatment of a unit of TSS (rate/1,000 pounds).
Ctss
=
Average BCUA municipal TSS concentration in milligrams per liter.
Commercial and Industrial Users
Re
=
[Rf + (1.5 x Rbod x Cbod x 8.34) + (1.5 x Rtss x Ctss x 8.34)] / 1,000,000
Where:
Rf
=
Current year's annual BCUA flow rate for treatment of a unit of wastewater flow (rate/million gallons).
Rbod
=
Current year's annual BCUA BOD rate for treatment of a unit of BOD (rate/1,000 pounds).
Cbod
=
Average BCUA municipal BOD concentration in milligrams per liter.
Rtss
=
Current year's annual BCUA TSS rate for treatment of a unit of TSS (rate/1,000 pounds).
Ctss
=
Average BCUA municipal TSS concentration in milligrams per liter.
(4) 
For all real property containing multiple dwelling units that are supplied water through an individual meter, the sewer usage for each dwelling unit shall be calculated based on the total sewer usage divided by the number of dwelling units.

B. 
Connection fee calculation. The sewer connection fee shall be $1,880 per equivalent dwelling unit as defined herein. The Borough shall recompute the sewer connection fee per equivalent dwelling unit at the end of each budget year as required by law. The number of equivalent dwelling units for all facilities shall be calculated as follows:
(1) 
A single-family dwelling unit shall be equal to one equivalent dwelling unit (EDU).
(2) 
For all other facilities, the number of equivalent dwelling units shall be calculated as the ratio of projected average daily usage of the proposed facility to the New Jersey Department of Environmental Protection's recognized single-family residential demand of 300 gallons per day or 108,000 gallons per year. The projected average demand for the facility shall be calculated using the flow standards adopted by the New Jersey Department of Environmental Protection "Projected Flow Criteria" established in accordance with N.J.A.C. 7:14A-23.3 and are incorporated herein by reference.
(3) 
If any existing building or buildings which are connected to the Park Ridge sewer system are located on the property to be developed and will be disconnected prior to the construction of the new facility, the equivalent dwelling units shall be calculated as the ratio of the projected net increase in the average daily usage of the proposed facility pursuant to the NJDEP-recognized single-family demand of 300 gallons per day or 108,000 gallons per year. The projected average net increase in the average daily usage shall be calculate as the difference between the projected average daily usage of the proposed facility less the prior year's average daily usage of the existing facilities that will be disconnected. The sewer connection fee shall be based upon the net average increase.
