Dear Christine,
On March 7, 2024, the Animal Feeding Operations Program of the Division of Water Resources
issued the subject Additional Information Request. We respectfully submit below, responses to
the individual requests:
Request: Pipe and Pit P-1 Location — The location of the pipe between P-1 and P-2 on
Drawing 22301-G-100 is shown to be between Barn 100 and the waste pond. However,
photographs and notes from DWR staff indicate that the pipe appears to have been installed
in/along the south and west sides waste pond embankment. DWR staff also expressed
concern regarding the installation of P-1; indicating that P-1 appears to have been installed in
the waste pond or have disturbed the waste pond embankment. Please provide engineering
design details for any and all locations where a waste storage structure or lagoon was or is to
be disturbed. Provide installation details. A Professional Engineer will need to specifically
certify that any damage to a waste pond or lagoon has been repaired to meet NRCS
Standards.
Response: Please see the attached AYES drawing dated March 17, 2024 showing engineering
and design details for P-1, P-2, and associated piping where the wastewater storage structure
was disturbed. This is an as -built drawing showing the correct locations of the installed pits and
piping and it is sealed and the work is certified by an AYES PE.
2. Request: Influent/Effluent Sampling — Please indicate location for sampling of influent to
and effluent from each digester. Your January 19, 2024 response stated that this information
is included in the O&M Plan. Please indicate, specifically, where this information can be
found. The O&M Plan should clearly state the location for influent and effluent sampling.
This should also be shown on one of the diagrams.
Response: Please see the attached O&M Manual excerpt indicating the locations for sampling of
influent and effluent from the digester. The pits referenced in the description of the sample points
are shown on the PFDs/P&IDs.

3. Request: Digester Berm/Stormwater Management —During the January site visit, Sustain
RNG staff indicated that a berm or some other stormwater management structures would be
put in place at the downslope of the digester. Please provide additional information regarding
planned stormwater management.
Response: Please see the attached letter from the Lincoln County Natural Resources
Department stating that the land disturbance activity was found to be in compliance with the
Lincoln County Soil Erosion and Sedimentation Control Ordinance and the North Carolina
Sedimentation Pollution Control Act of 1973 and has been completed.
Respectfully,

Version 1.0
Beam Dairy Manure Anaerobic Digester Sampling Program
A. Obiective
To establish a standardized procedure for collecting and analyzing samples from the influent
and effluent of a dairy manure anaerobic digester to ensure optimal operation and compliance
with environmental regulations.
B. Sampling Frequency
1. Influent: Grab samples to be collected twice weekly. Samples will be collected from pit #5
(MRP).
2. Effluent: Grab samples to be collected twice weekly. Samples will be collected from pit #6
(digester discharge).
C. Sample Collection
1. Equipment: Use clean containers for sample collection.
2. Procedure:
- For influent, collect samples before the manure enters the digester. Use sample container
attached to long handle pole.
- For effluent, collect samples where the manure exits the digester.
- Take grab samples from a consistent location each time to maintain comparability.
- Label each sample with the date, time, and specific location of collection.
D. Shipping to Laboratory
- Pack samples in a cooler with ice packs to maintain a temperature below 4°C.
- Ship samples to the laboratory on the day of collection for timely analysis.
E. Laboratory Analysis
- **Parameters to be analyzed**:
- pH
- Chemical Oxygen Demand (COD)
- Biological Oxygen Demand (BOD)
- Total Suspended Solids (TSS)
- Volatile Fatty Acids (VFA)
- Ammonia -Nitrogen (NH3-N)
- Total Kjeldahl Nitrogen (TKN)
- Phosphorus
- Methods: Follow standard methods for the examination of water and wastewater. Only labs
meeting required standards for testing will be utilized. All testing methods will be reviewed and
approved by the Sustain RNG technical team, led by Jim Wallace, PhD.
