WASTE DISCHARGE REQUIREMENTS ORDER NO. R5-2014-0006 _20- FORWARD INC.AND REPUBLIC SERVICES INC. FORWARD CLASS II LANDFILL SAN JOAQUIN COUNTY b. Waste will be spread thinly, no more than 3 inches deep, to ensure complete drying within five days. c. Waste will be turned twice daily with a cultivating device to facilitate drying. 83.Groundwater degradation with nitrogen species such as ammonia and nitrate can be prevented by minimizing percolation below the root zone of crops and ensuring that the total nitrogen load does not exceed crop needs over the course of a typical year. Where there is sufficient unsaturated soil in the vadose zone, excess nitrogen can be mineralized and denitrified by soil microorganisms. 84.Excess BOD is developed by excessive waste application that depletes oxygen in the vadose zone creating anoxic conditions. At the surface, this can result in nuisance odors and fly- breeding. When insufficient oxygen is present below the ground surface, anaerobic decay of organic matter can create reducing conditions that convert naturally occurring metals from insoluble to a more soluble reduced form. This condition can be exacerbated by acidic soils and excess moisture. If reducing conditions do not reverse as the percolate moves down through the vadose zone, the dissolved metals (primarily iron, manganese and arsenic) can degrade shallow groundwater quality. Many aquifers contain enough dissolved oxygen to reverse the process. ANTIDEGRADATION ANALYSIS FOR LAND APPLICATION OF CANNERY WASTE 85. State Water Resources Control Board Resolution 68-16 ("Policy with Respect to Maintaining High Quality Waters of the State") (hereafter Resolution 68-16) prohibits degradation of groundwater unless it has been shown that: a. The degradation is consistent with the maximum benefit to the people of the state. b. The degradation will not unreasonably affect present and anticipated future beneficial uses. c. The degradation does not result in water quality less than that prescribed in state and regional policies, including violation of one or more water quality objectives, and d. The discharger employs best practable treatment or control (BPTC) to minimize degradation. 86. Degradation of groundwater by some of the typical waste constituents associated with discharges of decompostable organic waste, such as cannery waste is not consistent with the maximum benefit to the people of the state when there are other viable means of disposal that would have less environmental impact, such as use for livestock feed. 87.Groundwater quality has been monitored at the site since 1988. Based on the data available, it is not possible to determine pre-1968 groundwater quality. Therefore, determination of compliance with Resolution 68-16 for this facility must be based on existing
