(a) The volume of flow used in determining the total discharge of wastewater for payment of user charges and surcharges shall be based on the following: (1) Metered water consumption as shown in the records of meter readings maintained by WSACC.. If a person discharging wastewater into the public sewers produces evidence to the Executive Director that a significant percent of the total annual volume of water used for all purposes does not reach the public sewers, then an estimated percentage of total water consumption to be used in determining; non - domestic wastewater discharge may be agreed upon between the Fxecutive Director and the person discharging such non - domestic wastewater into the public sewer. The EXeLUtive Director shall ascertain whether substantial evidence has been provided to prove a significant percent of water does not reach the pubic sewers; or (2) if required by WSACC or at the individual discharges option, other flow monitoring devices which measure the actual volume of wastewater discharged to the sewer. Such devices shall be accessible and safely located, and the measuring system shall be installed in accordance with plans approved by WSACC and the governing municipality. The metering system shall be installed and maintained at the user's expense according to arrangements that may be made with 'WSACC. (3) Where any user procures all or part of his water supply from sources other than WSACC, the user shall install and maintain at his own expense water meters of a type approved by WSACC for the purposes of determining the proper volume of wastewater discharged to such sewers. (b) The character and concentration of the constituents of wastewater used in determining surcharges shall be determined by samples collected and analyzed by WSACC. Samples shall be collected in such manner as to be representative of the actual discharge and shall be analyzed using procedures set forth in 40 CFR Par? 136. (c) The determination by the Executive Director or his duly appointed representatives of the character and concentration of the wastewater discharge shall be binding as a basis for charges. (d) Any source that discharges non - domestic wastewater in excess of the levels listed above may be subject to surcharges. (e) The Executive Director may assess surcharges to users to recover any additional costs incurred by WSACC for the handling and disposal of sludge. 3.4 Pretreatment Program Administration Chare-es The schedule of charges and fees adopted by WSACC may include charges and fees for: (a) reimbursement of costs of setting up and operating the pretreatment program; 23 Attachment number 4 H -3 Page 278
