WASTE DISCHARGE REQUIREMENTS ORDER NO. - 16- CALIFORNIA NATURAL PRODUCTS WASTEWATER TREATMENT FACILITY SAN JOAQUIN COUNTY c. By 4 December 2003, the Discharger shall submit a Salinity Reduction Workplan that identifies ways to reduce the salinity of wastewater discharged to the land application areas. The workplan shall identify high strength waste streams and means to remove or reduce their loading rate to the wastewater system, alternative chemicals that can be substituted that will result in better crop uptake, and opportunities to reuse/recycle high strength wastewater that will result in reduced loading rates. The workplan shall include an implementation schedule. d. By 5 January 2004, the Discharger shall submit an Operation and Maintenance (O&M) Plan for the wastewater treatment facility land application areas and landscaped areas. The O&M Plan shall instruct field personnel on how to manage the day-to-day discharge operations to comply with the terms and conditions of this order and how to make field adjustments, as necessary, to preclude nuisance conditions (e.g., standing water, runoff from landscaped areas, and objectionable odors from ponded wastewater). It shall also - include a nuisance condition troubleshooting flowchart and a description of notification requirements if bypass occurs. Operating personnel shall keep a copy of the O&M Plan at the facility for reference. Key operating personnel shall be familiar with its contents. e. By 5 January 2004, the Discharger shall submit an evaluation of the Septic Tank Use and condition. The evaluation should describe the use of the tanks, types and volume of wastewater discharged to the tanks, describe the size and construction of the tanks and leachfrelds, and summarize maintenance of the tanks and leachfields. If the tanks are deemed inadequate for the intended purpose and may cause degradation of groundwater quality, a schedule for improvement of the septic tanks or connection to the City wastewater system shall be provided. Alternatively, in lieu of submitting the evaluation, the Discharger may submit a schedule for connection of all domestic waste streams to the City wastewater system. f. By 2 April 2004, the Discharger shall submit a Groundwater Well Installation Report. The report shall be consistent with, and include the items listed, in the second section of Attachment C. g. By 30 June 2004, the Discharge shall submit a Salinity Reduction Implementation Report that describes the improvements that have been constructed or procedures implemented, which result in reduced wastewater salinity. h. By 1 June 2005, the Discharger shall submit a Groundwater Quality Study Report. For each groundwater monitoring parameter/constituent identified in the MRP, the report shall present a summary of monitoring data, calculation of the concentration in background monitoring wells, and comparison of background groundwater quality to that in wells used to monitor all four land disposal areas. Determination of background quality shall be made using the methods described in Title 27, Section 20415(e)(10), and shall be based on data from at least four consecutive quarterly(or more frequent) groundwater monitoring events. For each monitoring parameter/constituent, the report shall compare measured VN.�w Joaquin Non]5 StaF60bl'1<nTSan Joaquin\Cal Nab Pmduns\WDR 07MW RJuly 03.dm
