WASTE DISCHARGE REQUIREMENTS ORDER R5-2013-0028 -19- <br /> DELICATO VINEYARDS, INC. <br /> DELICATO FAMILY VINEYARDS <br /> SAN JOAQUIN COUNTY <br /> expansion to 72 MGY with 130 acres of LAAs. Below is a summary of current and <br /> projected BOD loading estimates for the proposed modified LAAs. <br /> Total Annual Flow Land Application Area Max BOD Loading <br /> (MGY) (lbs/ac/day) <br /> Current: 48.1' 202 Acres (Uncropped): 285 <br /> Phase I: 56 23 Acres (Cropped): 106 <br /> 107 Acres (Vineyards): 76 <br /> Phase II: 72 23 Acres (Cropped): 183 <br /> 107 Acres (Vineyards): 105 <br /> ' 2002-2011 average. <br /> 2 2012 RWD calculations for existing conditions were based on 20 acres of LAAs. <br /> The projected future BOD loading rates are moderate and should not pose a threat <br /> of nuisance or pollution. <br /> Antidegradation Analysis <br /> 79. State Water Resources Control Board Resolution 68-16 ("Policy with Respect to <br /> Maintaining High Quality Waters of the State") (hereafter Resolution 68-16) <br /> prohibits degradation of high-quality groundwater unless it has been shown that: <br /> a. The degradation is consistent with the maximum benefit to the people of the <br /> state. <br /> b. The degradation will not unreasonably affect present and anticipated future <br /> beneficial uses. <br /> c. The degradation does not result in water quality less than that prescribed in <br /> state and regional policies, including violation of one or more water quality <br /> objectives, and <br /> d. The discharger employs best practicable treatment or control (BPTC) to <br /> minimize degradation. <br /> 80. The Discharger has been monitoring groundwater quality at the site since 2001. <br /> Although a winery has operated at the site since 1924, it is not possible to <br /> determine pre-1968 groundwater quality for the shallow groundwater at or <br /> upgradient of the site. Therefore, determination of compliance with <br /> Resolution 68-16 for this facility must be based on available ambient background <br /> groundwater quality. <br /> 81. Constituents of concern that have the potential to degrade groundwater are TDS, <br /> sodium, chloride, sulfate, nitrate, and manganese are summarized in the following <br /> table and paragraphs: <br /> Constituent Effluent and Groundwater Potential <br /> Concentrations (m /L) Water Quality <br />
