Steve Gikas and Lori Gikas -2- 26 September 2013 Golden Gate Nut Company/California Nuggets, Inc. Discharge Requirements that will ensure compliance with applicable policies and regulations. The burden, including costs of the reports, bears a reasonable relationship to the need for the reports because this information was previously required by the Cleanup and Abatement Order and in addition, is necessary in order to prepare Waste Discharge Requirements. Pursuant to Water Code section 13267, the Board hereby orders GGNC/CNI-to submit a technical report that contains the following information by 15 October 2013. Items 1 through 4 shall be prepared by a registered professional engineer or geologist. 1. A preliminary engineering evaluation of options for structural and operational improvements to the wastewater treatment, storage, and disposal system designed to ensure that: a. The conditions that lead to the current groundwater pollution will be stopped; b. Shallow groundwater-gaahty-will be restored to a non-polluted condition within a reasonable timeframe; and c. GGNC/CNI will fully implement best practicable treatment or control of the discharge to ensure compliance with the Basin Plan by a date certain, which will be set by the Board. The evaluation shall include specific future dates (after adoption of WDRs) by which GGNC/CNI proposes to complete the final evaluation and selection of treatment/control options, and to fully implement the selected options. 2. Definition of the volume of the existing lined wastewater pond with two feet of freeboard (based on the measured geometry, including depth, of the pond); the date of liner installation for the pond; and documentation of construction quality assurance measures and liner leak testing performed prior to liner acceptance (if any exists). 3. A water balance based on current wastewater character and flows that demonstrates: a. The additional LAA acreage required to prevent overloading with water, nitrogen, BOD, and salts. b. The volume of additional wastewater storage required. The water balance must demonstrate adequate wastewater storage and disposal capacity for both the average rainfall year and the 100-year return period total annual precipitation, including consideration of at least the following: • A minimum of two feet of freeboard in each pond at all times (unless a registered civil engineer determines that a lower freeboard level will not cause overtopping or berm failure). • Historical local evapotranspiration, pan evaporation, and lake evaporation data (monthly average values). • Local precipitation data with the 100-year return period annual total distributed monthly in accordance with mean monthly precipitation patterns. • Proposed land application area hydraulic loading rates distributed monthly in accordance with expected seasonal variations based on crop evapotranspiration rates. 4. A description of the specific structural and operational controls that have been, or will be, implemented to ensure that wastewater does not leave the designated land application
