Environmental Protection Agency (EPA) approved techniques. Sampling methods, location, times, durations, and frequencies ate to be determined on an individual basis by the Approving Authority. The Approving Authority may inspect the monitoting facilities of any industrial wastewater discharger to determine compliance with the requirements of this Ordinance. The Discharger shall allow the Approving Authority or its representatives, upon presentation of credentials of identification, to entet upon the ptemises of the Discharger foc the purposes of inspection, sampling, or records examination. Should the industrial waste discharger at any time, for any reason, cefuse to allow inspection of the records relating to industrial discharges, then the Approving Authority is hereby expressly authorized to seek a Special inspection warrant under Section 66.122 of the Wisconsin Statutes. (1) Monitoring Facilities Each person discharging industrial process wastewater shall provide and maintain at the Discharger's own expense, a monitoring facility to allow inspection, sampling, and flow measurement of each wastewater discharge to the wastewatet system. Each monitoring facility shall be situated on the Dischargez's premises, except where such a location would be impcactical or cause undue hardship on the Discharger, the Authority may concur with the monitoring facility being constructed in the public street or sidewalk area provided that the facility is located so that access will not be obstructed. There shall be ample room in and near each facility to allow accutate sampling and prepacation of samples for analysis. Plans for the monitoring facility and sampling and measuring equipment shall be approved by the Appzoving Authority prior to commencement of construction. The facilities, including all equipment and appurtenances, shall be accessible at all times and shall be maintained at all times in a safe and proper operating condition at the expense of the Discharger. All monitozing facilities shall be constructed and maintained in accordance with all applicable construction standards and specifications.

(D) Prov� �on fo D d� �on In the event that a person discharging industrial waste into the public sewers ptoduces evidence satisfactory to the Approving Authority that a percentage of the total annual volume of water used for all purposes does not reach the public sanitary sewer, then the determination of the water consumption to be used in computing the waste volume and strength discharged into the public sanitary sewer may be made a matter of agreement between the Approving Authority and the person discharging the waste. Devices for measuring water not discharged to the sanitary sewers may be required by the Approving Authority. :i�• � . - - r- - (1) Domestic Category A is defined as normal or domestic wastewater having organic concentrations of biochemical oxygen demand (BOD), suspended solids and phosphorus no greater than 210, 340 and 12 milligrans per liter (mg/1), respectively. The sewer charge for Category A wastewater is as follows: Minimum Charge - 53.40 per billing period Volume Charge - 50.85 per 100 cubic feet (a) Summer Sprinkling Rates The Sewer Utility will adjust the sewage bills for the months o£ August, September and October, which represent consumption that occurred during the summer months. The bills will be based on the average of the previous three quarters of consumption or upon the actual consumption, whichever is lower. The above sewage rates will apply only to those indi- viduals who have resided at the indicated address for at least four quarters. Anyone who has not acquired a full year of water consumption is ineligible for the summer rates . 21 - llu - ORDINANCE # 6 Residential customers who do not have the necessary consumption record referred to above to be eligible £or the reduced summer sewerage billing may, upon request to the City Department of Administration, be granted the summer credit based on either an established pattern o£ consumption that includes the summer quarter at a previous Oshkosh address, or acceptable quarters before and/or after said summer quarterly billing. Excluded from the summer wat er pollution control rates are those residences which have installed a metering device which purports to measure the amount of water that does not enter the sanitary sewers (deduct meters). These consumers will be filled on water consumption that actually enters the sanitary sewer. (2) Commercial Those commercial establishments which discharge wastes of the same pollutional strength as domestic sewage will be billed at the Category A rate as set forth in Section 24- 6.5(E)(1). Commercial firms which discharge wastes exceeding domestic sewage in strength will be billed at the Category B rate as set forth in Section 24-6.6(E)(3).

(3) Industrial Industries discharging wastes into the public sanitary sewer system shall be billed in accordance with the Category B Wastewater Service charge if theiz wastewaters have net loadings gzeater than that of the domestic concentrations as defined in Section 24-6.6(E)(1) above.

The Category B Wastewater Service Charge shall reflect the unit costs of treating the volume of wastes and, BOD, suspended solids, and phosphorus. The Category B charge is as follows: Fixed Charge - 53.40 per billing period Volume - 30.37/100 cubic feet BOD - 30.166 pound Phosphorus - 51.00/pound The Category B charges for volume, BOD, suspended solids and phosphorus shall be computed in accordance with the formula presented below: C1 = Charge to industry for collecting and treating BOD, suspended solids, and phosphorus.
