According to SCS Field Services, Inc.,the landfill gas collection and destruction system experienced the following periods of downtime during the second quarter 2014: • April 30,8:45 a.m.—9:18 a.m.:Flare A-2 shut down for alarm testing. + April 30, 12:08 p.m.—3:20 p.m.:Flare A-2 shut down for alarm testing and system maintenance. • May 1,3:26 am.—1:13 p.m.:Flare A-2 shut down for system construction activities. • May 3,2:37 a.m.—8:53 a.m.:Flare A-2 shut down for system construction activities. • May 3,9:20 am.—12:23 pm.:Flare A-2 shut down for system construction activities. • May 5, 11:00 a.m. —12:47 p.m.:Flare A-2 shut down for testing. + May 5, 1:46 p.m.—2:12 p.m.:Flare A-2 shut down for testing. • May 6, 11:48 a.m.—3:16 p.m.:Flare A-2 shut down during testing of Flare A-1. • June 17, 11:19 a.m.—2:16 p.m.:Low temperature shut down of Flare A-2. • June 25,4:43 a.m.— 11:39 am.:Flare A-2 shut down for system construction activities. Based on information provided by SCS Field Services,Inc.,the landfill gas extraction and destruction system operated at approximately 1,800 to 3,011 cubic feet per minute during the second quarter 2014. This is equivalent to about 2,592,000 to 4,345,840 cubic feet per day. Based on the June 25, 2013 Annual Compliance Emissions Test Report prepared by Blue Sky Environmental, Inc., Flare A-2 destroys an average of 12.7 lbs/hour of non-methane organics, and back-up Flare A-1 destroys an average of 10.7 lbs/hour of non-methane organics. Non-methane organics are considered equivalent to VOCs. During the period of April 1 through June 30,2014,Flare A-2 operated approximately 2,145 hours out of a possible 2,184 hours (98.2% operational rate). At the average VOC destruction rate provided in the Source Test Report,Flare A-2 destroyed approximately 27,242 pounds of VOCs during the second quarter 2014.
