WASTE DISCHARGE REQUIREMENTS ORDER R5-2013-0028 -40- DELICATO VINEYARDS, INC. DELICATO FAMILY VINEYARDS SAN JOAQUIN COUNTY ii. Pre-reduction flow estimates and analytical results for all contributing waste streams, and estimated annual mass discharge rates for TDS, FDS and key salinity constituents (i.e., sodium, chloride, sulfate, and potassium), as performed to comply with CAO R5-2004-0705 . iii. Current flow estimates and analytical results for all contributing waste streams, and estimated annual mass discharge rates for TDS, FDS and key salinity constituents (i.e., sodium, chloride, sulfate, and potassium). iv. Comparison of pre-reduction and current mass discharge rates to quantify the salinity reduction that was achieved after adoption of CAO R5-2004-0705. v. An evaluation of the feasibility of additional salinity control measures above and beyond those that have already been implemented. Estimates of capital and operation/maintenance costs for each option shall be provided. h. By 1 May 2015, the Discharger shall submit an Agricultural Beneficial Uses Study Report that documents a study of local agricultural uses of groundwater; the types of crops that are or could be grown in the area based on climate and soil type; and an assessment of the water quality needed to sustain reasonable crop yields. The study shall include information on the history of irrigation water supply sources and a review of published information regarding the salinity of local groundwater prior to 1968. The study area shall include at least properties within one mile of the facility. Information sources and published references shall be cited and appended if not prohibited by copyright. The report shall evaluate and propose site-specific numeric water quality objectives to interpret the Basin Plan's narrative objectives for protection of agricultural beneficial uses of groundwater for TDS, EC, sodium, and chloride. i. By 1 February 2017, the Discharger shall submit a Pond Liner Integrity Evaluation Workplan that specifies the means and methods that the Discharger proposes to use to evaluate all geosynthetic liner systems to comply with Discharge Specification B.16. j. By 1 May 2018, the Discharger shall submit a Groundwater Limitations Compliance Report that demonstrates statistically significant decreasing trends in groundwater for TDS, sulfate, sodium, chloride and manganese in each compliance well. If compliance with Groundwater Limitation G.3 is not demonstrated for each constituent in each well, the report shall include a description of the specific additional treatment or control measures that will be implemented to achieve compliance with the Groundwater Limitations unless the report demonstrates that another source of pollutants is
