4. Quality Surcharge Fee.
(a) Quality Surcharge Fee Requirement. The Sewer Service Charge (SSC), as established under Sections 64.41 of the Code, recovers the cost of treatment of domestic strength wastes discharged to the POTW for treatment. The SSC is paid by all of the users of the POTW. However, industrial wastewater discharged by Industrial Users (IUs) can vary significantly in strength from that of domestic sewage. Industrial wastewater strength can be higher or lower than that of the domestic sewage. A permittee whose discharge is determined to contain BOD or SS, as defined in Subsection A of Section 64.00 of this Code, with concentrations in excess of the designated BOD and SS values in the Board Rules and Regulations shall pay a quality surcharge fee.
(b) Quality Surcharge Fee Determination. A fee based on the quality/strength of the Wastewater discharged into the POTW shall be paid quarterly in arrears by all Industrial User or permittees in possession of a valid Industrial Wastewater Permit where the Wastewater of said permittees is found to be subject to the City’s Quality Surcharge Fee and which is treated in a City treatment plant. The permittee may choose to be billed for the City’s Quality Surcharge Fee based on either the provisions of Subsections 64.30D4(b)(1) or 64.30D4(b)(2) below.
(1) Permittees whose discharge is determined to contain BOD or SS, as defined in Subsection A of Section 64.00 of this Code, with concentrations in excess of the designated BOD and SS values in the Board Rules and Regulations shall pay a Quality Surcharge Fee (QSF) according to the following formula and provisions.
The Quality Surcharge Fee, for these permittees, shall be determined pursuant to the following formula:
C = V [ a(SS-DSS) + b(BOD-DBOD)]k
“C” is the Quality Surcharge Fee.
“V” is the average daily volume of wastewater discharged in gallons and shall be deemed (1) the volume of water supplied to the premises, adjusted as determined by the Board to account for water not discharged into the POTW (2) the metered volume of wastewater discharged into the POTW, in accordance with a measuring device approved by the Board, or (3) a figure determined by the Board, based upon any other equitable method.
“SS” is the suspended solids as defined in Subdivision 75 of Subsection A of Section 64.00 of this Code, expressed in milligrams per liter.
“BOD” is the biochemical oxygen demand of the wastewater as defined in Subdivision 6 of Subsection A of Section 64.00 of this Code, expressed in milligrams per liter.
“DSS” is the suspended solids concentration designated by the Board in the Board Rules and Regulations.
“DBOD” is the biochemical oxygen demand concentration designated by the Board in the Board Rules and Regulations.
“a”, is the verifiable cost assessed for each pound of suspended solids, as determined by the Board.
“b”, is the verifiable cost assessed for each pound of biochemical oxygen demand, as determined by the Board.
“k” is (365 x 8.34)/1,000,000, a dimensional constant to convert C to dollars.
If the term containing SS or BOD is negative, a value of zero shall be used for the term.
(i) In determining the amount of Quality Surcharge Fee to be paid by various industrial users, the Board may establish industry-wide averages for SS and BOD values. The Board may group permittees into appropriate discharge volume ranges each of which shall be represented by an average discharge volume. Where sampling and volume measurements of any permittee are not practical for physical, economic or other reasons, these averages may be used in establishing such permittee’s Quality Surcharge Fee.
(ii) Any permittee whose fee has been determined in the above manner who is not satisfied that the averages are applicable to its discharge, may submit appropriate engineering data to the Board for its consideration. If the Board finds that such permittee’s discharge differs significantly from the averages established, it may determine the fee on a more appropriate basis.
(2) Permittees whose discharge is determined to contain BOD or SS, as defined in Subsection A of Section 64.00 of this Code, with concentrations less than the designated BOD and SS values in the Board Rules and Regulations may petition the Board to pay a Low-Strength SSC Rate as defined in Section 64.41.01(n), of the Code. Upon qualification, such permittee may be allowed to pay a Low-Strength SSC Rate where the Low-Strength SSC Rate excludes the cost component associated with the domestic sewage strength included in the SSC rate. However, should such a permittee petition and be allowed to pay a Low-Strength SSC Rate, such permittee shall simultaneously become subject to the Zero-Based Quality Surcharge Fee (QSF) as defined in Subsection 64.30D4(c) below. This fee is to recover the treatment cost associated with removal of BOD and SS, as defined below, in the permittee’s discharge. This fee is also representative of and a replacement for the strength cost component of the Sewer Service Charge (SSC) not included in the Low-Strength SSC Rate as defined in Section 64.41.01(n) of the Code.
The Quality Surcharge Fee, for these permittees, shall be determined pursuant to the following formula:
C = V [ a(SS) + b(BOD)]k
where:
C, V, a, b, k, BOD and SS are defined under Section 64.30, Subsection D4(b) above.
(c) Zero-Based Quality Surcharge Fee Qualifications and Requirements. Any discharger, in possession of a valid Industrial Wastewater Permit, that petitions to pay a Low-Strength SSC Rate and a Zero-Based QSF, shall meet the following qualifications and requirements:
(1) The discharger, if not in possession of a valid Industrial Wastewater Perrmit, must apply for and obtain an industrial wastewater discharge permit as defined under Subsection 64.30.C.1. of the Code.
(2) The permittee must petition, in writing, to the Board to be placed on the Zero-Based Quality Surcharge Fee;
(3) The permittee must submit analytical data of its discharge, at the time of and with its petition, to demonstrate that the strength of its discharge does qualify for the Low-Strength SSC Rate;
(4) The permittee shall become subject to self monitoring of its discharge, per Industrial Waste Management Division policies and also as defined and established in Section 9 of the Board’s Rules and Regulations and,
(5) The permittee shall install a sampling facility, for the purposes of self-monitoring, in accordance to the requirements set forth by the Director.
(d) Determination of Surcharge Fees for Ground Solid Wastes. Where ground solid wastes such as garbage, market refuse, food plant wastes and hospital wastes are discharged to the POTW, their weights shall be recorded prior to disposal or may be estimated by the Board, and a dry weight loading calculated for determination of surcharges. Food processors which grind food plant wastes for discharge to the POTW and hospitals which grind infectious wastes for discharge to the POTW may be required to report quarterly the total weight of material ground for surcharge determination.
