down due to power failure; resumed Flare at 7am on auto mode. Personnel monitored flare start up. Collected data for CLF and RR1. Collected data for CLF and RR1. Flare shut down at 10:45am to 1:15pm. While Flare was shut down the flow meter was replaced. Flare shut down to install new PLC by Pat Cullen and Pat Doresy. The Flare was shut down from 9:45am to 11:45am. Meeting with Mario and Lou to discuss mowing at CLF and RR1. Collected data for CLF and RR1. Turned Flare off at 9:50am to Grease blowers and exercised valves. Also changed 2032 batteries in PLC. Collected data on CLF. Installed program on computer to view Yokogawa data, then uploaded data from Yokogawa onto program. Collected data for CLF and RR1. Greased blowers and exercised valves at Flare. Took monthly readings of flow meter. Pat Cullen and Kevin worked on Flare from 11am to 12pm. Supplies delivered for landfill restoration projects. Collected data on CLF and RR1. Construction project started by Cornerstone and Croton landfill crew. Isolated RR1 header from Flare so work could begin. CLF crew excavated a 6" header near RR1 EW-23. They then proceeded to cut the pipe and drain the water that was causing the blockage. To remediate the water issue in the RR1 header, the CLF crew along with cornerstone created a trap. The trap would collect the water from the header and drain it to a nearby leachate manhole, all while keeping the system free from 02. Tested the RR1 header for air leaks by applying vacuum at the flare. Then tested the quality of gas at the flare to monitor for air leaks. The RR1 header showed low 02, which meant the work had been successful. Changed PID at flare from -15.0 to -14.0 Greased blowers and exercised valves at Flare. Took monthly readings of flow meter.

CLF crew along with Cornerstone camera main header to find an air leak on RR1. A break in the header was discovered near RR1 EW-19. The header was broken at a Y section of the pipe. We proceeded to excavate and replaced the cross section of pipe. Collected data on CLF and RR1. Turned on East header of CLF Greased blowers and exercised valves at Flare. Took monthly readings of flow meter. Excavated RR1 EW-7 to remove water from line. Flare shut down at 7:00am due to power outage. Monitored the restarted of the Flare at 9:15am. Greased blowers and exercised valves at Flare. Flare shut down at 2:45am due to power outage. Monitored the restarted of the Flare at 7:15am. Flare was shut down at 10:45 for work to be done on the PLC by Pat Cullen. Monitored the restarted of the Flare at 1:30pm. JM from Cornerstone came to bore test gas migration areas near the Parks department's bathhouse, which is located along the North West side of CLF. Collected data along the north header on CLF. Fixed two wells in the process on collecting data, well EW-2 and EW-15. Collected data on CLF and RR1. Removed water from vaults on RR1 Greased blowers and exercised valves at Flare. Took monthly readings of flow meter. Removed water from vaults on RR1 then proceeded to collect data. Collected data on CLF and RR1. Flare was shut down at 9:00am to work on new lighting. Monitored the restarted of the Flare at 11:00am. Shut Flare down to switch out nitrogen tank. Monitored the restarted of the Flare. CLF crew began investigation into the North header on CLF. We cut into the header and sent a camera in to find water or obstructions. No water or obstructions were found. Cornerstone instruction on how to record data for well field. Proceeded to collect data for the month for CLF and RR1. Crew continued camera work on CLF headers. Greased blowers and exercised valves at Flare. Took monthly readings of flow meter. 2014 Work and Activity Performed October 10, 2014 • October 17-21, 2014 October 27-28, 2014 • • November 3, 2014 • • November 10, 2014 November 18-21 2014 December 2, 2014 December 4, 2014 • • • • • • • • • December 8, 2014 December 15-19, 2014 • • • Investigated RR1
