A. Calculating User Surcharge: The user charge of each large commercial-industrial user and tax-exempt user and small nonresidential commercial user shall be calculated by the user by the table set forth in Section 8-1-10 of this Chapter.
B. Billing: The Sanitary District will bill tax-exempt users who elect to pay on an annual basis pursuant to subsection F of this Section for the user surcharge due. Any large commercial-industrial user which owes a user surcharge shall remit the amount of the user surcharge simultaneously with the certified statement. The Sanitary District shall also bill any user who is in any manner delinquent in the performance of its obligations under this Chapter. The billing frequency shall be not more than once per month, nor less than once per year. All such bills shall be due and payable twenty (20) days after the date thereof. The Sanitary District reserves the right to bill delinquent users based on estimated quantities.
C. Interest: Interest at the rate of seventy-five one-hundredths percent (0.75%) per month or for any fraction thereof shall be added to any overdue payments. Such interest shall accrue from the date any remittance was due until the same is paid. Interest shall not be charged upon previously assessed and unpaid interest.
D. Reevaluation Of Remitted Amounts; Additional Bills: The Sanitary District shall reevaluate any and all data and certified statements submitted to it by a user pursuant to this Chapter, reevaluate its own data, call for more data or develop additional data as it deems necessary and subsequently bill the user for any deficiency indicated as due thereafter. The transmittal of any bill to a user shall not stop the District from rebilling for any deficiency determined to exist due to any subsequent reevaluation.
E. Residential Users: Users in this case shall under no circumstances be billed by the Sanitary District, nor be liable to pay user surcharge under this Section.
F. Tax-Exempt Users Reporting Option: Tax-exempt users whose sewer discharge does not exceed:
1. A flow of twenty five thousand (25,000) gallons per day (94,625 liters per day); and
2. A BOD of twenty five (25) pounds per day (11.32 kilograms per day); and (Ord. 928, 3-6-1990)
3. A suspended solids of thirty five (35) pounds per day (15.88 kilograms per day); and whose sewer discharge does not contain toxic, hazardous or injurious materials as defined in Appendix A (see Section 8-1-14 of this Chapter), may petition the Sanitary District, in writing, to report and pay its user surcharge annually on the basis of Sanitary District approved estimates for flow or water meter readings, if available, BOD concentrations at 119 mg/l and suspended solids concentrations at 168 mg/l. Tax-exempt users which are not authorized to use this option shall report in accordance with subsection 8-1-9B3 of this Chapter. A user's petition hereunder shall be submitted to the Sanitary District with the filing of the annual certified statement. Such petitions may be granted or denied upon such reasonable terms and conditions as may be determined by the Sanitary District. (Ord. 928, 3-6-1990; amd. 1998 Code)
G. Adequate Measurement Facilities Option: Users presently without adequate individual facilities for the measurement of wastes as required in Section 8-1-9 of this Chapter must, during the period of construction of such facilities, file with the Sanitary District reasonable estimates of concentrations of BOD and suspended solids until such time as adequate facilities for measurement are installed; provided, that the following requirements are met:
1. The user files its election annually by January 1 or the first regular business day thereafter, of the current year; (Ord. 928, 3-6-1990)
2. The Superintendent of Public Works approves the estimated concentrations;
3. Volume of flow used for reporting quantities must be based on measured water use by the user;
4. The estimated concentration must be used throughout the year;
5. A date approved by the Superintendent of Public Works for the completion of measurement and sampling facilities, as required in Section 8-1-9 of this Chapter, must be given; (Ord. 928, 3-6-1990; amd. 1998 Code)
6. Upon completion of the measurement and sampling facilities, a sampling program, as described in Section 8-1-9 of this Chapter, must be instituted. The results of this sampling program will be used to calculate the user charge liability during the period covered by the election filing;
7. If the results of the sampling program (as mentioned in subsection G6 of this Section) show that the user charge liability of the company is greater than the amount estimated during the election filing period, the user shall pay the Sanitary District the additional user charge surcharge within ninety (90) days of the measurement and sampling facilities completion date. If the results of the sampling program show that the user's user charge liability is less than the amount estimated during the election filing period, the Sanitary District will credit the overcharge to the company's future user charge liability; and
8. If the user fails to pay the additional user charge liability as set forth in the foregoing subsection G7 of this Section within the ninety (90) day period, the Sanitary District will assess interest as described in subsection C of this Section. (Ord. 928, 3-6-1990)
A. Appeal To Superintendent Of Public Works: In the event that any user subject to this Chapter wishes to be heard regarding the amounts billed, its user classification or any other matters relating thereto, such user shall make a detailed written request to the Superintendent of Public Works to be heard, specifying the reasons therefor.
