Tom Wise - 2 - 4 February 2005 Designated waste means either of the following: (a) Hazardous waste that has been granted a variance from hazardous waste management requirements pursuant to Section 25143 of the Health and Safety Code. (b) Nonhazardous waste that consists of, or contains, pollutants that, under ambient environmental conditions at a waste management unit, could be released in concentrations exceeding applicable water quality objectives or that could reasonably be expected to affect beneficial uses of the waters of the state as contained in the appropriate state water quality control plan. Disposal Method Wastewater is discharged to a storm water pond on the east side of the facility. Discharge of the wastewater is not appropriate because the wastewater is not contained in a Class II impoundment, or adequately treated as required by Title 27 Section 20250. The discharge owastewater is likely to degrade groundwater quality by increasing the TDS concentration in groundwater. Conclusions Based on evaluation of the available data, wastewater generated at the facility is classified as designated waste as defined by California Water Code 13173(b). California Water Code Section 20090 does riot exempt the wastewater from the requirements of Title 27. Because the wastewater is designated waste, the discharge cannot be issued Waste Discharge Requirements that allow land application and are a violation of WDRs Order No. 96-117 Discharge Prohibition A.3, which states: Discharge of waste classified as "hazardous"or "designated, " as defined in Sections 2521(a) and 2522(a) of Chapter 15, is prohibited. Furthermore, WDRs Groundwater Limitations D.1,D.2, D.S, and D.6 are all applicable to the discharge because the result of the discharge is likely to impact groundwater quality. The WDRs' Groundwater Limitations state the following: The Discharge shall not cause underlying groundwater to: 1. Be degraded. 2. Contain chemicals, heavy metals, or trace elements in concentrations that adversely affect beneficial uses or exceed maximum contaminant levels specified in 22 CCR, Division 4, Chapter 15. I 5. Contain taste or odor producing substances in concentrations that cause nuisance or adversely affect beneficial uses. 6. Contain concentrations of chemical constituents in amounts that adversely affect agricultural use. The Title 27 program could possibly regulate the wastewater generated at the facility, but significant improvements to storage areas and/or treatment of the wastewater prior to discharge would be required to comply with Title 27 requirements.
