Water Quality Monitoring Report Forward Landfill compost facility received 24,877 tons of green waste and produced 10,291 tons of compost (Appendix A). During the fourth quarter 2017 monitoring period, Forward personnel reported water in the compost facility retention basin; however, no leachate from compost stockpiles or compost windrows was noted. The analytical results for the compost facility retention basin are discussed in Section 2.1.6. 1.5 Landfill Gas Monitoring In accordance with Title 27 California Code of Regulations (27CCR), Article 6, SCS Field Services (SCS) conducts quarterly gas monitoring of Title 27 perimeter gas probes, on-site structures at the Forward Landfill, and Point of Compliance (POC) landfill gas (LFG) monitoring probes. During the fourth quarter 2017 monitoring period, methane levels exceeded the regulatory limit of one percent by volume in two POC gas probes, while no methane was detected in the any of the on-site structures. As part of the CAP, Forward operates a landfill gas (LFG) extraction system to control LFG emissions (i.e. source control). Cornerstone Environmental Group (Cornerstone) and SCS perform the operations and maintenance (O&M) for the LFG extraction system and collected LFG is routed and split between the Ameresco Landfill Gas to Energy Facility (LFGEF) and Forward's blower/flare station (BFS). Summary tables for the BFS and LFG extraction wells, and the fourth quarter 2017 perimeter LFG monitoring probe and on- site structure testing report are presented in Appendix C. During the fourth quarter 2017 monitoring period SCS reported 43.3 hours of downtime for the BFS. Based on the BFS data prepared by Cornerstone, the instantaneous total flow rate of LFG readings taken December 22, 2017 was 1,464 standard cubic feet per minute (scfm) at the Ameresco LFGEF and 2,643 scfm at the Forward BFS. A summary of the LFG and destruction system operations and maintenance for the fourth quarter 2017 are presented in Appendix C. 1.6 Cannery Waste Land Application Monitoring Cannery waste and land application monitoring (CWLAM) and groundwater analytical results for the CWLAM detection monitoring system are presented in Section 3.1.6. Facility Inspection logs, weekly total mass nitrogen application, composite waste sample analytical results, and the annual land application monitoring summary were presented in Appendixes D and F of the Third Quarter 2017 Water Quality Monitoring Report — Forward Landfill. A nutrient management plan will be submitted to the RWQCB under separate cover. 1.7 Leachate Recirculation and Monitoring Leachate recirculation is performed at the Forward Landfill in accordance with the RWQCB approved Leachate Recirculation Plan dated March 3, 2017. The volume of leachate and a location map of the leachate recirculation (discharge) on the facility are presented in Appendix A. Leachate monitoring and analytical results for the Forward and Austin Units are presented in Sections 2.1.6 and 3.1.9, respectively.
