<br />(scfin), inlet pressure, outlet pressure, gas temperature at the inlet and outlet, and equivalent British
<br />Thermal Units (BTUs) consumed. The landfill gas collection and destruction system undergoes
<br />periodic maintenance to re -balance the collection vacuums to produce the highest percentage of landfill
<br />gas (e.g., methane) and to minimize the collection of oxygen.
<br />According to SCS Field Services, Inc., the landfill gas collection and destruction system experienced
<br />the following periods of downtime during the third quarter 2015:
<br />• July 10, 6:46 a.m. — 2:21 p.m.: Flares A-1 and A-2 down for testing.
<br />• July 14, 8:41 a.m. — 5:42 p.m.: Flare A-2 down for variable frequency drive (VFD) installation.
<br />• July 15, 7:44 a.m. —1:35 p.m.: Flare A-2 down for variable frequency drive (VFD) installation,
<br />• July 25, 9:02 a.m. —12:30 p.m.: Flare A-2 down due to construction activities.
<br />• July 30, 8:35 a.m. — 9:00 a.m.: Flare A-2 down due to construction activities.
<br />• August 6, 9:05 p.m. — 9:16 pm.: Flare A-2 down due to low temperature shutdown.
<br />• August 26, 7:32 p.m. — August 27, 8:00 a.m.: Flare A-2 due to low temperature shutdown.
<br />• September 11, 11:58 a.m. —12:04 p.m.: Flare A-2 down for low temperature shutdown test.
<br />• September 22, 7:13 p.m. — September 23, 5:06 p.m.: Flare A-2 down due to failure of
<br />compressor unit for auto shutdown valves.
<br />Based on information provided by SCS Field Services, Inc., the landfill gas extraction and destruction
<br />system operated at approximately 1,509 to 2,002 cubic feet per minute during the third quarter 2015.
<br />This is equivalent to about 2,172,960 to 2,882,880 cubic feet per day. Based on the data presented in
<br />the June 26, 2015 Annual Compliance Emissions Test Repoli prepared by Blue Sky Environmental,
<br />Inc., Flare A-2 destroys an average of 20.1 lbs/hour of non -methane organics, and back-up Flare A-1
<br />destroys an average of 17.6 lbs/hour of non -methane organics, Non -methane organics are considered
<br />equivalent to VOCs. During the period of July 1 through September 30, 2015, Flare A-2 operated
<br />approximately 2,147 hours out of a possible 2,208 hours (97.2% operational rate). At the average VOC
<br />destruction rate provided in the Source Test Report, Flare A-2 destroyed approximately 43,155 pounds
<br />of VOCs during the third quarter 2015.

<br />quarter 2015 as provided by SCS Field Services, Inc.
