2017 Semi -Annual Compliance Report
January 29, 2018
Overview of System Maintenance and Repairs
For the time period from July 1, 2017 through December 31, 2017, which is the period covered
by this report, all processes that comprise the innovative swine waste treatment system were
operational, and electricity generation was capable for the majority of the reporting period. The
following summarizes, in general, the operations of the system for the reporting period:
During the warmer, summer months, biogas production was substantial, and at times, the rate
at which biogas was accumulated and stored beneath the HDPE cover exceeded the capacity of
the microturbine, and the flare was used periodically to augment biogas use. During the
reporting period, the electricity generation system had an up -time of approximately 55% (102
days of 185), although there were 29 days with SCADA system errors that could have
erroneously reported uptime, so the actual uptime may have varied by as much as 15%. Down-
time resulted from maintenance activities (described in more detail, below) and scheduled
down -time due to reduced biogas production at the very end of the reporting period due to
cooler temperatures affecting biogas generation. The following graph illustrates the operating
times and amount of electricity generated by the system for the reporting period:

Although the generation reported from the SCADA system indicates approximately 85 MWh of
electricity generation for the period, the reported values from the electricity meter used for
measuring REC transfer to Duke Energy reports approximately 101 MWh of generation. The 16
MWh discrepancy can be attributed to the 29 days of SCADA reporting malfunction, as
described above. As an additional depiction of the electrical generation efficiency of the
system for the reporting period, the following graph illustrates the power generation rate,
expressed in kilowatts (kW). As typical, the generation efficiency increases in the cooler

Biogas flow is also monitored and recorded for the system. The disposition of the biogas may
only occur through use by the microturbine and flare, controlled release through venting, or
through leaks from the system, which cannot be measured. The following graph illustrates the
measured biogas usage for the system. Flare usage, as indicated by measured flow to the flare
meter, for the reporting period may also be surmised from the graph. It should be noted that
days that indicate zero flow may also indicate a disruption with the data acquisition system,
which was observed to occur more significantly in the latter half of 2017, as described above.

The environmental treatment system was operational for the entirety of the reporting period;
however, required maintenance activities and disrepair led to reduced duplicity of certain
environmental treatment system components, such as the aeration system pumps. The
anaerobic mixing system uptime was 75% for the reporting period, while the aeration system
uptime was reported as 53%. However, SCADA reporting errors, as described above, most likely
accounted for a lower reported uptime. Maintenance activities for the environmental
treatment system included mixing, jet motive, and flush pump maintenance, and repairs to the
cover (welding small cracks, holes, and tears resulting from normal wear).
The farm staff also experienced difficulty in maintaining a regular flushing schedule to remove
waste from the animal barns, which resulted in increased maintenance activities to ensure
environmental system operation. The following graph depicts operating times for the
environmental treatment system. Additional observations of system performance are noted in
the operator log included with this report.

Overall, the system performed very well during the reporting period - from power generation,
greenhouse gas emission reduction, and environmental performance perspectives. While no
major system disruptions or significant maintenance activities were required during the
reporting period, the following describes the routine activities invested in the system operation
(also noted in the operator log):

Site visit to check on why MT might have shut down other than low gas. Pumped surface water
and found the Gas MH half full of water and choking off gas flow. Pumped out MH and started
MT
8/16/2017
Site visit to take water samples. Discounted solar panel for manhole pump and hooked up a
battery charger to maintain battery life.
8/28/2017
Site visit to meet with Digester repair folks, they are replacing motor on pump 2 and I found that
pump 2 was in fault they checked it and it is running a little high in Amps. I did a walk on the
cover to check for leaks. Checked in with Kevin and checked out Basin pumps and cleaned up the
office some. We had a very hard time with pumps and valves and we may have a clogged pipe
We are running on one pump
8/29/2017
Site visit to continue work on the clogged digester pump. Stated MT and checking on some
meter issues
9/5/2017
Site visit able to unclogged dig pumps by back flushing using the aeration pumps and fire hose.
Hopping to get more gas from 2 pumps running now. System running good with gas we have.
9/6/2017
Site visit to check on computer issues, could not log on. Found plug breaker was tripped that ran
computer and internet, must of happen during thunderstorm last night. All other systems cont.
to run.
9/19/2017
Site visit to check. Found MT will not stay running. Contacted E-finity to log in and check system.
All else looks good, Skid is running and we have gas.
10/2/2017
Retook fecal sample out of aeration basin. Digester mixing pump still tripping breaker. Gas is
getting low, not sure how much longer we can run.
10/9/2017
The MT started stopping and starting again this morning. After talking with Efinity we
found a bad cooling fan that caused the electrical components to overheat. They are
going to try to overnight one and I can replace it in the tomorrow.
10/16/2017
MT has been down and we have a strong gas build up. I started Flare at 9:20 gas flow at 35
SCFM.Tech. worked on MT from 1-4:30 no avail we will continue to flare. Called Tech about one
digester pump he will get back to schedule a repair visit. System: # 2 Digester pump down and #
1 Digester pump kicks the breaker now and then. Basin all
systems are OK
10/19/2017
1 had shut the flare down at 6:30 Wednesday morning. Site visit to start flare MT is down start at
35 SCFM-- 8588502.1 System: # 2 Digester pump down and # 1 Digester pump kicks the breaker
now and then. Basin all systems are OK. Pumped surface water off NE corner of Digester. Used
Vacuum to clean out Gas MH. Used mulch mower to mow center Aisle between Digester and
Basin. I talked to Andrew on Monday about the need to mow rather than weed eat because of
the debris going into Basin.
10/25/2017
Got several problems with mixing pumps. Digester -Pump 1 broke the collar that connects the
motor to pump shaft -Pump 2 will run but trips the breaker some
Preferred Sources will be on site Mon, depending on if the new motor, for Pumps 2 if needed,
shows up this will Aeration -Pump 1 broken the belts (should be in next week)- Pump 2 will not
pump Thinking the intake side of the aeration line is clogged tried to back flush with digester
pump 2(when it is running) but not having any luck. Hopefully once we get both digester pump
running we can have more pressure to blow anything out of the Aeration line. Also with the new
belts for the aeration pump both of them running could be able to get pumping again.
10/26/2017
Efinity on site to repair MT, found bad liner and temp gauge in unit. Everything back up and
running. Mixing Pumps are still down.
10/27/2017
Mike with Pro'Pump was on site today hooking part of the new monitoring system for flush
pumps I worked with Andrew and Landon with their flushing clogged line and our pumps that
are down Josh Amon is supposed to be here to work on Dieser pumps next week A -Basin Pump
Belts should be here the first of next week

10/30/2017
Site visit to install new belts and get Basin Pumps running and back on line. Completed Primed
the pumps and they are now running and set on auto. We hope to get digester pumps up and
running Wednesday
10/31/2017
Site visit: I noticed the Basin Pumps had failed they were turning but not pumping. I shut them
down and worked the remainder of the day trying to get them to pump. I had very little success.
I will try again tomorrow. Josh Amon is scheduled to come to LRF to work on the Digester pumps
on Wednesday
11/1/2017
Site visit: Josh Amon came today and worked on both Digester pumps he and his helper were
from 10:15 until 6:00, he was able to get both pumps running but one has a leak in the priming
cap and is so full of sludge ha we had to shut it down. Josh will order and install a new cap. I
spent the whole day working on the Basin pumps. I finally had to open the right-hand pump and
found that the check valve flapper had broken off and was in the pump. I still could not get them
to prime and run. I contacted Mike Osborne and he is to send me some data. IU assisted Josh
with his repair in between my attempts.
11/6/2017
Site visit: I worked on getting the Basin Pumps to working I pumped and ran the Blower for
about 3.5 to 4 hrs. The digester (Only one was working) is clogged Kevin and I will work on it
tomorrow. I found a small snag (may have come from Mower) in the cover at the ground /cover
edge on the North side. I taped it and if we have time we might weld it tomorrow. I shut the MT
down to save the gas for tomorrow.
11/7/2017
Site visit: Kevin and Marvin met with Jeff C. and the testing team from Duke. The Chiller failed,
and we were unable to do gas test. Kevin called in for service on the chiller and conditioner and
they are scheduled to come to LRF tomorrow. Kevin and I were able to flush out the crossover
line Digester to Basin and flush out the Digester pump. The basin Pumps are still not working
properly. We will try again tomorrow.
11/8/2017
Site visit: I met with service man to find out about the chiller and after checking everything and
consulting with all the Tech discovered a bad heat exchanger and all the coolant had leaked out.
They are ordering the needed parts and will return to complete the service call as soon as
possible. The basin Pumps are still not working properly. I was able to remove the Vacuum gauge
and will get parts to re -install. We will try again tomorrow to get them running.
11/10/2017
Site visit: I met with service Tech and installed heat exchanger and loaded Glycol. I worked on
Basin Pumps and got them running for 6 hours with blower running 3 tried to restart them but
failed time for the man MT is running and I reattached cable for Flush Pump the crossover pipe is
flowing great. I am going home.

Water Quality samples were taken in each quarter. Results from these samples are
further detailed below. Air Quality samples were last taken in June 2017 representing
warm season, or summer, conditions; additional warm season samples will be taken in
the summer of 2018. Air quality samples representative of a cool season (winter)
conditions were taken on November 16, 2017. Results from these sampling efforts are
further detailed below.
a. Results of Waste Water Analysis
Water quality samples were taken in each quarter. Samples were analyzed by Research
Analytical Laboratories, Inc. in Kernersville. The initial 31 and 411 quarter samples
resulted in higher fecal coliform counts than expected, and thus, and additional sample
was taken. The re -sampling resulted in lower, compliant results. The following table

b. Results from Ammonia Emissions Sampling and Analysis
Emissions from Animal Waste Treatment and Storage System
Ammonia nitrogen emissions from the aeration basin and lagoon were quantified to determine
if significant volatilization of NH3-N occurred from this part of the waste management system.
Emissions from the water surfaces were determined using a buoyant convective flux chamber
(BCFC) which method was described in details and illustrated with pictures in the February 15,
2012 report. Sampling took place on November 16, 2017 between 10 am and 12:30 pm. It was a
nice and sunny day, relatively windy (2-5 m/s). Temperature was 65 F.
Results were as follows:
• Size of the chamber: 50.8 cm wide by 53.3 cm long and 2.5 cm in height.
• Air sampling flow rate: 0.40 L/min
• Average ammonia concentrations in sweep air from the aeration basin while aeration was
off: 28 ppm (4 samples) or on average in mass concentration 0.0159 g-N/m3
Loyd Ray Farms, Inc.
Innovative Animal Waste Management System Permit No. AW1990031 Page 11 of 18

2017 Semi -Annual Compliance Report January 29, 2018
• Ammonia concentrations in sweep air while aeration was on was not measured, earlier
monitoring indicated that ammonia concentration in sweep air during aeration was slightly
lower.
The total emission from the aeration basin can be calculated from the air sampling flow rate, the
surface of the chamber and the surface area of the aeration basin. The latter surface is
nominally 24,500 ftZ (or 2277 M2). Emission rate is calculated as follows:
NH3 emission rate = NH3 concentration x Sampling flow rate x Aeration basin area / Buoyant chamber
area
After unit conversion, one obtains values of 3.2 g/h. This corresponds to a NH3 emission rate of
0.538 kg NH3-N/week. This is a very low value compared to the allowable emissions of 106 ke
NH3-N/week from the swine waste treatment and storage structures as specified in Section
1.6.a.i of the Swine Animal Waste Management Permit.
Surface emission rate of NH3 from the lagoon was determined following the same method.
Average concentration of ammonia in the sweep air (with the same chamber and at the same
flowrate of 0.4 L/min) was 21.3 ppm. With the surface area of the lagoon (19,425 M2), emission
of NH3 from the lagoon are estimated to be 3.50 kg NH3-N/week.
Results for the emissions from the aeration basin and the lagoon are summarized in the table
below. Total ammonia (TAN) in the aeration basin and lagoon at the time of sampling is also
reported for information and were relatively low. The low overall emissions reported this period
are consistent with the lower than usual TAN concentrations. These numbers all show the
system is performing well.

Emission rate

3.50 kg NH3-N/week
Total emission (lagoon +
aeration basin)
4.04 kg NH3-N/week
Thus, together lagoon and aeration basin contribute to the emission of 4.04 kg NH3-N/week.
This is well below the allowable 106 kg NH3-N/week.
Emissions from the Barns
Ammonia emissions from the barns were also determined on June 6, 2017. It should be noted
that accurate determination of emissions from animal houses is a difficult exercise. This is
because of the variable nature of the emission, the difficulty in accurately measuring air flow
from the fans on the animal houses, and the fact that fan operation is automated, i.e., they are

reported below exist and can be important.
Ammonia in the exhaust air from the barns was determined using Draeger tubes. Details on the
concentrations and number of fans on at the time of sampling are shown in the table below.

The total emission of ammonia can be estimated by multiplying the ammonia concentration in
each of the barn's exhausts by the exhaust flowrate of that barn (33,000 cfm for large fans and
13,000 cfm for the small fans). At the time of sampling, total exhaust flow was 342,000 cfm and
concentrations ranged from 2 to 10 ppm (see Table above). The calculated total weekly
ammonia emissions from the barns was 320 kg 1411113-N/week.
Adding the emission from the treatment system and the lagoon (4.04 kg NH3-N/week) to the
emissions from the barns (320 kg NH3-N/week) amounts to a total of 324 kg NH3-N/week from
the swine farm. This is below the allowable value of 476 kg NH3-N/week specified in Section
1.6.a.iii of the Swine Animal Waste Management Permit.
Emissions from the Sprayfield
Emissions from the sprayfield were not assessed during this reporting period due to previously
reported complications in performing the assessment and inability to detect emissions from the
sprayfields from previous attempts by Duke University.

6. Odor Sampling
l
Results of odor sampling — 11/16/201�
Odor was monitored to comply with Section 1.6.b.ii of the Swine Animal Waste
Management Permit. One monitoring event was conducted on November 16, 2017.
Sampling took place at about 10 am. It was a nice.and sunny day, unusually warm for
the season (65 F) but relatively windy (2-5 m/s). Several measurements for wind speed
and direction were taken to ensure that data were representative. The average wind
speed was 3.1 m/s, however, the wind speed was very variable with strong gusts of
variable direction up to 4.5 m/s. The wind direction and points for monitoring odor are
shown in Figure 1, below.
Odor was monitored by Marc Deshusses. Odor panelist rules were listed in the previous
report and are not repeated here. Odor was monitored using a Nasal Ranger
(http://www.nasalranger.com/) field olfactometer, following the manufacturer
recommended instructions.

Odor could not be detected at the 2 D/T level. This indicates that the odor level was
lower than 2 D/T. Then the Nasal Ranger was taken off the nose and ambient air was
sniffed and compared to odorless air from the Nasal Ranger. This was to determine
whether a difference could be detected between ambient air and odorless air from the
Nasal Ranger. No significant difference could be detected.
Sampling downwind
Odor sampling at location #1 found odor at the 2 D/T level. The measurement was
difficult to reproduce as odor (as recorded without the olfactometer) was typically
coming in gusts with the wind. Note that Location #1 is not at the property line.
Sampling was repeated a little further away at location #2. No odor could be detected at
the 2 D/T level. This indicates that the odor level was lower than 2 D/T. Then the Nasal
Ranger was taken off the nose and ambient air was sniffed and compared to odorless air
from the Nasal Ranger. This was to determine whether a difference could be detected
between ambient air and odorless air from the Nasal Ranger. No significant difference
could be detected.
These results indicate that odor levels complied with Section 1.6.b.ii of the Swine Animal
Waste Management Permit

This Semi -Annual Compliance Report provides an overview of the manner in which the subject
facility has maintained compliance with the conditions of the Innovative Animal Waste
Management System permit for the reporting period from July 1, 2017 through December 31,
2017. During this reporting period, the system was operated in accordance with the Innovative
Swine Waste Treatment System, and subject to the requirements thereof.
In addition to addressing compliance with the conditions of the permit, this report provides a
brief overview of the system maintenance and repairs (page 5-7) and then lists all sampling and
reporting requirements per the Innovative Animal Waste Management System Permit, No.
AW1990031 (page 8-10). For each requirement, this report records monitoring that occurred
and a brief explanation for each (page 10-15).
The report was completed on behalf of Loyd Ray Farms, Inc., by Cavanaugh & Associates, P.A.,
under the direction of the Duke Carbon Offsets Initiative (DCOI). Please contact Matt Arsenault
at 919-613-7466 with any questions. A copy of this report will be provided to Loyd Ray Farms,
Inc., and will be maintained on -site with the other permit compliance documentation.

2017 Semi -Annual Compliance Report

Overview of System Maintenance and Repairs
For the time period from July 1, 2017 through December 31, 2017, which is the period covered
by this report, all processes that comprise the innovative swine waste treatment system were
operational, and electricity generation was capable for the majority of the reporting period. The
following summarizes, in general, the operations of the system for the reporting period:
During the warmer, summer months, biogas production was substantial, and at times, the rate
at which biogas was accumulated and stored beneath the HDPE cover exceeded the capacity of
the microturbine, and the flare was used periodically to augment biogas use. During the
reporting period, the electricity generation system had an up -time of approximately 55% (102
days of 185), although there were 29 days with SCADA system errors that could have
erroneously reported uptime, so the actual uptime may have varied by as much as 15%. Down-
time resulted from maintenance activities (described in more detail, below) and scheduled
down -time due to reduced biogas production at the very end of the reporting period due to
cooler temperatures affecting biogas generation. The following graph illustrates the operating
times and amount of electricity generated by the system for the reporting period:

Although the generation reported from the SCADA system indicates approximately 85 MWh of
electricity generation for the period, the reported values from the electricity meter used for
measuring REC transfer to Duke Energy reports approximately 101 MWh of generation. The 16
MWh discrepancy can be attributed to the 29 days of SCADA reporting malfunction, as
described above. As an additional depiction of the electrical generation efficiency of the
system for the reporting period, the following graph illustrates the power generation rate,
expressed in kilowatts (kW). As typical, the generation efficiency increases in the cooler

Biogas flow is also monitored and recorded for the system. The disposition of the biogas may
only occur through use by the microturbine and flare, controlled release through venting, or
through leaks from the system, which cannot be measured. The following graph illustrates the
measured biogas usage for the system. Flare usage, as indicated by measured flow to the flare
meter, for the reporting period may also be surmised from the graph. It should be noted that
days that indicate zero flow may also indicate a disruption with the data acquisition system,
which was observed to occur more significantly in the latter half of 2017, as described above.
