WASTE DISCHARGE REQUIREMEMTS ORDER NO. -9- CITY OF ESCALON ESCALON WASTEWATER TREATMENT FACILITY SAN JOAQUIN COUNTY statistically greater than background (upstream) surface water quality. Background surface water quality shall be determined when the required monitoring program provides sufficient data. F. Provisions: 1. As described in Discharge Specification B.2, the Discharger shall submit a technical report which describes the implemented WWTP improvements. The report is required at least 30 days prior to the Discharger's desire to increase the flow rates as described in Discharge Specification B.3. 2. By 1 January 2001, the Discharger shall submit a technical report, prepared under the supervision of a registered engineer, which identifies sources of TDS in industrial wastewater, and recommends ways to reduce TDS. The report shall also evaluate reclamation alternatives both at the industrial discharger facilities and the WWTP. The report shall present a tabulation of all data used in evaluating the industrial wastewater flow. 3. By 1 January 2001 Discharger shall submit a Sludge Management Plan which describes the annual volume of sludge generated by the facility and specifies the proposed testing and disposal practices. 4. By 31 May 2001, the Discharger shall submit a report, pursuant to Section 13267 of the California Water Code, indicating whether the discharge to the ponds has caused, or is likely to cause, constituent concentrations to exceed background concentrations. The report shall be prepared under the supervision of a registered geologist or registered engineer. If monitoring data indicates wastewater has degraded groundwater quality beyond background concentrations, the Discharger shall submit a Wastewater Disposal Mitigation Plan (WDMP) within 90 days of request by the Executive Officer. The WDMP shall address the magnitude and extent of groundwater contaminants, evaluate contaminant control alternatives, evaluate appropriate effluent limits, and select a preferred contaminant control alternative. The selected contaminant control alternative must comply with State Water Resources Control Board Resolution No. 68-16, Title 27 CCR, and the most recent Basin Plan. The WDMP shall include a proposed project schedule for design and construction. 5. The Discharger shall comply with Monitoring and Reporting Program No. , which is part of this Order, and any revisions thereto, as ordered by the Executive Officer. 6. The Discharger shall comply with the"Standard Provisions and Reporting Requirements for Waste Discharge Requirements", dated 1 March 1991, which is attached hereto and made part of this Order by reference. This attachment and its individual paragraphs are commonly referenced as "Standard Provision(s)".
