Environ. Healthl MfMICES 304 Weber Ave. 3rd Floor Stockton, CA 95202 There is apparently some misunderstanding of how waste should be classified and managed at Forward landfill. Waste Discharge Requirements Order No. R5-2003-0049 (WDRs) permit Forward Inc. and Allied Waste Industries to discharge designated waste, nonhazardous solid waste, and inert waste to constructed waste management units. All three of these waste classes may be discharged to Class II waste management units at the facility. while Class III units may not accept designated wastes, even as daily or interim cover material. Section 13173 of the Water Code defines designated waste as 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- arrrbient 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." Without a variance from DTSC, hazardous waste may not be discharged at the Forward facility. Therefore, any nonhazardous waste that contains soluble constituents that poses a threat to water quality may only be discharged to a Class II waste management unit. Contaminated soils accepted at the facility for disposal or for use as cover material must also be classified and managed according to the above requirements. Monitoring and Reporting Program No. R5-2003-0049 (a part of Forward's WDRs) sets specific designated levels for soluble cadmium, chromium (VI), copper, lead, mercury, nickel, zinc, TPH- diesel, TPH-gasoline, and BTEX. The WDRs allow waste containing these constituents to be discharged to a Class III waste management unit only if the WET extract concentrations are below the designated levels. Wastes containing these specified constituents at or above the designated levels may be discharged to Class II units. The WDRs do not establish designated levels for other constituents. However, all designated waste must be discharged to a Class II unit. It is the responsibility of the discharger and the landfill to characterize and classify the waste for appropriate disposal. In 1989, all Class III landfills in the Central Valley Region were sent information (copy attached) on how to properly classify waste for acceptance at their facilities. Page 3 of that letter presents a formula for determining designated levels. To further assist in making these determinations, the attached document "Recommended Waste cceptance Limits for Inorganics at Class III Landfills" (recommended limits) may be used as California Environmental Protection AAenc Ca Recycled Paper
