R� REPUBL 1 C f!i' SERVICES Mr. Brendan Kenny Engineering Geologist Central Valley Regional Water Quality Control Board 11020 Sun Center Drive, Suite 200 Rancho Cordova, CA 95670 July 25, 2016 RE: Forward Landfill—Second Quarter 2016 Dear Mr. Kenny: In accordance with WDR Order No. R5-2014-0006, Forward Incorporated (Forward) is pleased to submit this Second Quarter 2016 Monitoring Report for the Forward Landfill. According to the Forward Landfill Operations Manager, standard observations have been conducted weekly during the reporting quarter. The Forward Landfill Operations Manager also reported that no surface water was discharged from the facility during the reporting period. During the second quarter 2016 monitoring period, notices of violation (NOVs) were issued by the Central Valley Regional Water . Quality Control Board (RWQCB) for Illegal acceptance of hazardous waste from Woodland Biomass, incomplete monitoring of the landfill and compost facility, exceedances of the nitrogen loading limit for the cannery waste land application area, exceedances of the water quality protection standards in several groundwater monitoring wells, and submittal of an incomplete monitoring report. Forward is currently preparing formal responses to these NOVs. For the Forward Unit, environmental monitoring for the second quarter 2016 yielded results similar to previous quarters. A non-statistical indication of release was identified at wells MW-16 and MW-17 as a result of one or more volatile organic compound (VOCs)measured at quantifiable concentrations. For the inorganic monitoring parameters, one or more concentration limits(CLs)were exceeded at wells MW-2A, MW-10, MW-18, MW-19, MW-22, and MW-24. Verification sampling for the organic and inorganic CL exceedances is scheduled for July 2016. For constituent concentrations in "tracking mode", increasing temporal trends were calculated for diisopropyl ether in well MW-16 and for carbon tetrachloride and chloroform in well MW-17. Surface water monitoring stations were reported dry during the second quarter 2016 monitoring period. For vadose zone monitoring no VOCs were detected in the sample collected from lysimeter LY-BG-1; all of the other lysimeters were reported dry. For the Austin Unit, one CL was exceeded for nitrate as nitrogen in well AMW-12. In addition, the WQPS for iron was exceeded at well AMW-10. Verification sampling for wells AMW-10 and AMW-12 is scheduled for July 2016. Although, several CLs were also exceeded in well AMW-6, it is recognized that well AMW-6 should have been identified as a CAP well in the M&RP. For the corrective action program (CAP) wells, 16 of 28 wells reported one or more VOCs exceeding a practical quantitation limit (PQL), with CAP well AMWA having the greatest number of VOCs (14), including 10 measured above a PQL. For surface water, toluene was detected at a quantifiable concentration at background surface water monitoring station ASW-1, no other CL exceedances were noted for during the second quarter 2016 monitoring period. Since surface water station ASWA is currently dry, verification sampling will be performed during the next sampling event when flow is reported at ASW-1. For the vadose zone, seven VOCs were measured in the sample collected from suction lysimeter FU-05, all of the other lysimeters
