State Digester General Permit — Design Revision
Dear Ms. Lawson,
Roeslein & Associates, on behalf of the farm owner, hereby submits the following revision for digester design at Hot Dog Farm #2.
As discussed, we are revising the design to eliminate the mixing well at the digester. This mixing pump pulled water from the
digester and discharged water back into the digester. Influent into the digester will either come from a wet well lift station between
the barns and digester or directly from the barns via gravity pipe. The sampling protocol document verbiage has been updated to
clarify that all digester influent sampling will be taken via cleanout in the influent piping prior to entering the lagoon.
To facilitate your review of the enclosed documentation, the following is an itemized breakdown:
1. One (1) revised copy Sampling Protocol and Schedule
2. One (1) copy of revised General Arrangement Plan to reflect eliminated mixing pump
3. One (1) copy of revised Hydraulic Profile Plan to reflect eliminated mixing pump
Please do not hesitate to contact me or my office if you have any questions, comments or require any additional information.
Thank you,
G . ;�

Sampling protocol and schedule for Monarch sites
Date: 08/23/2024
R08.23.24
Sample collection at all sites should be done using the sampling protocol outlined below. A submittal sheet will be sent to the person in charge
of sampling prior to sampling. The respective person is responsible for print submittal forms, conducting sampling, label samples as per submittal
form, safely storing (refrigerated containers during storage) and shipping samples to the respective lab (instructions on submittal form)
Required accessories:
1. Telescopic sampler extendable to 18 feet and the pendulum beaker
2. Gloves and sampling containers
3. Ice packs.
4. Sampling submittal forms
5. Safety supplies
During sampling event two people should be responsible while supporting tasks (shipping etc.) can be conducted by the person in charge alone.

Sampling protocol for digester samples
1. Influent and effluent samples are intended to be collected for all sites from shortlisted digesters on a quarterly basis. Sampling to be
conducted by two persons at the site.
2. Label all sampling containers with respective sampling ids.
3. The influent sample must be collected from a "cleanout" just prior to entering the lagoon using the telescopic sampler and 5-gallon
bucket while following all site -specific safety policies, including Lagoon Access Safety Procedure
4. The effluent sample must be collected from the crossover pipe/wet well using the telescopic sampler and 5-gallon bucket while following
all site -specific safety policies, including Lagoon Access Safety Procedure
5. Procedure for sample collection from a Cross over pipe
a. On opening the valve on crossover pipe it is recommended to allow enough time to pass such that the standing debris in the
pipe is flushed out and a good representative sample can be collected.
b. Collect 3 x 500 mL samples using the sampler into a clean 5-gallon bucket.
c. Repeat this procedure 2 more times, while collecting all the samples into the same 5-gallon bucket.
d. Allow sufficient time between two collection events such that pipe contents are flushed.
e. At the end of the sampling event, you may have — 1.3-1.5-gallon sample, homogenize the contents of the bucket gently mixing
using the sampler and the pendulum beaker on the sampler.
6. Sampling for sample collection from a wet well or cleanout.
a. Using the telescopic sampler (beaker attached to the rod) gently homogenize contents of the wet well.
b. Collect 6-8 beakers of sample into a 5-gallon bucket from different areas of the wet well/cleanout to get a representative sample.
c. Gently homogenize the contents of the bucket.
7. Grab a sample from the homogenized mixture to fill the labeled sampling container (influent or effluent) and put the container cap
tightly ensuring a watertight seal.
8. If the samples are to be stored for more than 2 hours before shipping, store them in a refrigerator preferably 4°C or lower.
9. If refrigeration is not available use frozen icepacks to cool the samples and replace icepacks at regular intervals, store the samples in a
well -ventilated space.
10. DO NOT STORE SAMPLES IN REFRIGERATORS MEANT FOR FOOD STORAGE
11. Ship samples to the lab (details in the submittal form) to deliver overnight. Include ice packs in the shipping box to keep samples cool
during transit.

Sampling protocol for lagoon liquid samples (Secondary lagoon
1. Lagoon liquid samples are intended to be collected from all the open lagoons at every site on a quarterly basis.
2. Label all sampling containers with respective sampling ids. (Refer sample list for Sample IDs)
3. The sample must be collected from the multiple spots (6-8) in the open lagoon using the telescopic sampler and 5-gallon bucket while
following all site -specific safety policies, including Lagoon Access Safety Procedure
4. Use the 18 feet telescopic sampler to reach lagoon water surface from the berm, it is needed that the sampling in charge is accompanied
by another operator onsite for this sampling for ease of equipment handling and safety.
5. Collect 2 x 500 mL samples at each spot, using the sampler into a clean 5-gallon bucket.
6. Repeat this procedure at all 6-8 randomly chosen spots along with periphery of the lagoon, collect all the samples into the same 5-gallon
bucket.
7. At the end of the sampling event, you may have — 1.3-1.5-gallon sample, homogenize the contents of the bucket gently mixing using the
sampler and the pendulum beaker on the sampler.
8. Grab a sample from the homogenized mixture to fill the labeled sampling container and put the container cap tightly ensuring a
water/airtight seal.
9. If the samples are to be stored for more than 2 hours before shipping, store them in a refrigerator preferably 4C or lower or use frozen
icepacks to cool the samples in a small container and replace icepacks at regular intervals, store the samples is a well -ventilated space.
10. DO NOT STORE SAMPLES IN REFRIGERATORS MEANT FOR FOOD STORAGE
11. Ship samples to the lab (details in the submittal form) to deliver overnight. Include ice packs in the shipping box to keep samples cool
during transit.

Sludge survey and sampling from secondary lagoon
1. The secondary lagoon, source of sludge, will be examined for sludge levels once every four years.
2. Sludge levels in the covered digesters will be examined once every four years appropriate sludge management plans will be put in
place to keep sludge levels in the digester under control.
3. Sludge sampling, from the secondary lagoon, will be conducted during sludge management events to determine sludge
composition especially Nitrogen, Phosphorus, potassium, and other micronutrients.
4. This sampling protocol is intended to help evaluate progression of sludge level in the secondary lagoon and covered digeste and
ensure agronomic land application.
5. Sludge sampling will be conducted using a sludge judge, while sludge surveys will be conducted using sonar devices that can be
remotely controlled from the berm following all site -specific safety policies, including Lagoon Access Safety Procedure.
