Application No. ADS310239
Please see below for responses to the request for additional information, dated June 18, 2024, in relation to the digester permit
application for Melvin Bostic Farm. The original Additional Information Request is attached.
o Mailing Address
• The mailing address in the application has been revised to the correct location. Please reference revised Digester
Volume Calculations issued as part of these responses.
o Setbacks
• The digester setback markings have been revised to better reflect the shape of the digester and provide accurate
measurement from the perimeter of the top of the embankment. Please reference revised drawing RA270-27000-2
issued as part of these responses.
The landowner has obtained a signed waiver from Janice Bland regarding the 1500 foot setback requirement. This
document has been included in the application. Please reference waiver letter issued as part of these responses.
o Waste Level Gauge
• The waste levels in the digester will be measured by a level gauge in the digester wet well. Detail RA-STD-274-2 WET
WELL LEVEL INDICATOR has been revised to better convey this information. Please reference revised detail drawing
issued as part of these responses.
• A gravity transfer line will be installed between existing lagoon 27500A and 27500B. The following verbiage has been
added to the Digester Volume Calculations page in the permit application:
To avoid over -filling Lagoon 27500B in the event of a historic rainfall, it is the recommendation of Roeslein that pumping
begins at 460,667 cuft. This would reduce the operating height of Lagoon 27500B from 10.65 ft. to 10.13 ft. (44.63 ft.
elevation). This modification will ensure the 12 in. of freeboard required (per the NRCS Anaerobic Digester standard) in
Lagoon 27500B after the historic rainfall event.
Please reference revised Digester Volume Calculations issued as part of these responses.
o Liner Thickness
• The new digester will be lined with 60-mil HDPE material. The Digester Narrative has been revised to state that a 60-mil
thick HDPE liner will be installed (not 80-mil). Please reference revised Narrative issued as part of these responses.
Page 1 of 2

ENCINEERS • MANUFACTURERS • CONSTRUCTORS
o Irrigation Map
• The irrigation map has been included in the Waster Utilization Plan (WUP). It has been marked up to note the removal of
two existing pulls 6A, 6B, & 7. Please reference revised WUP plan issued as part of these responses.
o Emergency Action Plan
• An Emergency Action Plan specific to anaerobic digesters has been included in the application. Please reference
Environmental Spill Response and Common Safety Practices for On -Farm Anaerobic Digestion Systems documents
issued as part of these responses.
o Operation and Maintenance Plan
• The Anaerobic Digester System 0&M states that, "Sample tests should be performed periodically and to permitting
requirements, to allow evaluation of the wastewater."; pg. 6 of 17. A daily and weekly inspection checklist is provided on
pg. 17 of 17. Sampling schedule and protocol is included with recordkeeping data tables provided on pg. 5 of 5.
o Stormwater Outlet
• The drawings have been revised to indicate both sets stormwater (cover rainwater) outlet locations on site. Detail RA-
STD-277 RAINWATER OUTLET has been added to the drawing set. Please reference revised drawing RA270-27000-3
and detail drawing RA-STD-277 issued as part of these responses.
o Biogas Use as a Renewable Energy Resource
• Session Law 2023-63 — We intended to be using the generated gas as a renewable energy source within 6 months of gas
production. We will provide a portable, temporary flare as needed while commissioning the digester if we are not able to
use the gas within this timeframe. The digester permit application cover letter and digester narrative have been revised
to state this. Please reference these revised documents issued as part of these responses.
• The location of the temporary flare has been indicated on the GENERAL ARRANGEMENT drawings. Please reference
revised drawing RA270-27000-3 issued as part of these responses.
o Air Quality Permitting
• A copy of the Air Permit Applicability request letter issued to the NCDEQ on May 31, 2024 has been attached to the
comment responses. This letter is referenced in the digester permit application cover letter.
Please let us know if you have any further comments or need any further information. Thank you.
Sincerely,
Roeslein & Associates, Inc.

State Digester General Permit
Dear Ms. Lawson,
AFO Permit Application
Roeslein & Associates, on behalf of the farm owner, hereby submits the following application to NCDEQ Division of Water
Resources for review of the State Digester General Permit application package for Melvin Bostic Farm. The subject project is
located in Duplin County, North Carolina.
The digester constructed on this property will meet setback parameters as required per the Swine Farm Siting Act with the
exception of the 1500 ft. residence setback. The farm owner has obtained a signed waiver from Janice Bland as the digester is
approximately 1400 ft. from her residence. The digester is beyond 2500 ft. from any public building, beyond 500 ft. from property
lines, and beyond 500 ft. from any public water source.
Subsurface drain tile in the area of the new digester will be relocated according to NRCS standard to a minimum distance of 15
feet beyond the embankment toe.
Digester influent and effluent will be sampled from wet wells on site per the Sampling Protocol and Schedule document in this
package. The digester water level will be monitored by a level gauge installed in the digester -lagoon transfer wet well.
The digester will generate approximately 27,000 SCF of gas per day. This biogas is intended to be used within 6 months of
beginning to collect gas. A portable flare unit will be connected to an emergency vent at the digester if needed. Spare parts for
the gas upgrading systems will be kept on the shelf so readily available as needed. The digester cover will be provided with
emergency vents which are strategically located away from barns/public but still provide access for operators. Safety procedures
for venting covers are called out in the 0&M document. See Narrative for more information.
Per the Air Permit Applicability Request for Register 1 cluster of farms, submitted to NCDEQ Division of Air Quality, the annual
emission rates from the gas upgrading system associated with this farm are below the thresholds indicated in 15A NCAC
02Q.0102(d) and therefore does not require an air permit.
To facilitate your review of the enclosed documentation, the following is an itemized breakdown:
1. One (1) original "State Digester General Permit Application" application form.
2. One (1) copy of signed Janice Bland setback waiver.
3. One (1) copy of the engineering calculations.
4. One (1) copy of a detailed narrative of the Swine Digester Animal Waste Management System.
5. One (1) copy of Digester 0&M Procedures, Sampling Protocol, and Emergency Action Plan.
6. One (1) copy of the FEMA FIRM map labeled with the "proposed Digester Site".
7. One (1) copy of the new Waste Utilization Plan
8. One (1) copy of the permit form Section 3.6 components.
9. One (1) full-size set of the engineering plans, as well as one (1) 11x17" set.

R&A Project RA270-23
Issued 240425
Farm will utilize existing barns with slotted floors over flushing pits to collect manure. The farm
operators use pull plug system and recycle water for flushing to manage the animal manure. As part of
this current project, a new anaerobic lagoon digester will be installed, and the animal manure will be
redirected to the new digester. After treatment in the in anaerobic digester, the effluent will flow into
the existing lagoon. There is no change to the existing farm operations, nor the volume of wastes
generated. The effluent water will be recycled back to the barn for pit recharge or irrigated in
accordance with the existing Waste Utilization Plan (WUP).
Upon flushing, the wastewater from the barns will be directed into a properly designed lift station
through a 12-inch diameter gravity pipe header. There will be two pumps in the lift station wet well and
each pump is designed for 100% of the design flow.
The lift station pump will be 20 HP GEA pump, designed for a flow of 689 gallons/minute, through 6-inch
diameter, HDPE SDR 17 force -main into the new anaerobic lagoon digester.
The approximate dimensions of the new anaerobic lagoon digester are 285 feet by 140 feet with a total
volume of 315,936 cubic feet and a treatment capacity of 241,140 cubic feet at operating level.
Before the excavation, the project area is stripped approximately 6 inches of topsoil and will be
stockpiled. Embankment material will be free of sod, roots, and other objectionable material. The
maximum thickness of each compacted layer will be 6-inches and compacted to 95% of Standard Proctor
at -1 to +3 percent of optimum moisture content per ASTM D698. Each lift shall be tested for moisture
and density. The stockpiled topsoil will be spread on the outside bank.
After the construction the lagoon, and all required pipe penetrations, the inside walls of the lagoon will
be smooth rolled prior to the installation of the baseliner. The baseliner will be 60-mil think HDPE
synthetic liner. After the liner is installed, it will be tested for leaks prior to filling the lagoon with
wastewater.
There will be an outlet structure with a weir (level control) that keeps the water level inside the digester
at a constant level. The effluent will gravity flow through a 12-inch diameter digester outlet pipe to the
level control wet well and gravity feed into the existing lagoon through a 12-inch diameter pipe.
Once the lagoon is within in 2 feet of the normal operating level, a floating cover will be installed to
capture the biogas produced by the anaerobic digestion of the organic wastes in the wastewater. The
captured biogas will be blown to a micro -gas cleaning skid at an adjacent farm where it will be treated to
produce renewable natural gas (RNG).

To avoid over -filling Lagoon 27500E in the event of a historic rainfall, it is the recommendation of Roeslein that pumping begins at 460,667 cuft.
This would reduce the operating height of Lagoon 27500E from 10.65 ft. to 10.13 ft. (44.63 ft. elevation).
This modification will ensure the 12 in. of freeboard required (per the NRCS Anaerobic Digester standard) in Lagoon 27500E after the historic rainfall event.

*Note: A 25-year storm creates 24937.5 cuft of water. Added to the High Pump Elevation of the new Digester, this raises the water elevation to 92.84
ft. This provides 12.78 in. of freeboard, meeting the standard 12 in. required per the NRCS Anaerobic Digester standard.

Irrigation
The waste from your animal facility must be land applied at a specified rate to prevent pollution
of surface water and/or groundwater. The plant nutrients in the animal waste should be used
to reduce the amount of commercial fertilizer required for the crops in the fields where the waste
is to be applied.
This waste utilization plan uses nitrogen as the limiting nutrient. Waste should be analyzed
before each application cycle. Annual soil tests are strongly encouraged so that all plant
nutrients can be balanced for realistic yields of the crop to be grown.
Several factors are important in implementing your waste utilization plan in order to maximize
the fertilizer value of the waste and to ensure that it is applied in an environmentally safe manner:
1. Always apply waste based on the needs of the crop to be grown and the nutrient
content of the waste. Do not apply more nitrogen than the crop can utilize.
2. Soil types are important as they have different infiltration rates, leaching potentials,
cation exchange capacities, and available water holding capacities.
3. Normally waste shall be applied to land eroding at less than 5 tons per acre per
year. Waste may be applied to land eroding at 5 or more tons per acre annually, but
less than 10 tons per acre per year providing that adequate filter strips are established.
4. Do not apply waste on saturated soils, when it is raining, or when the surface is frozen.
Either of these conditions may result in runoff to surface waters which is not allowed
under DWR regulations.
5. Wind conditions should also be considered to avoid drift and downwind odor
problems.
6. To maximize the value of the nutrients for crop production and to reduce the potential
for pollution, the waste should be applied to a growing crop or applied not more than
30 days prior to planting a crop or forages breaking dormancy. Injecting the waste or
disking will conserve nutrients and reduce odor problems.
1 of 11

This plan is based on the waste application method shown above. If you choose to change
methods in the future, you need to revise this plan. Nutrient levels for different application
methods are not the same.
The estimated acres needed to apply the animal waste is based on typical nutrient content
for this type of facility. In some cases you may want to have plant analysis made, which could
allow additional waste to be applied. Provisions shall be made for the area receiving waste to
be flexible so as to accommodate changing waste analysis content and crop type. Lime must
be applied to maintain pH in the optimum range for specific crop production.
This waste utilization plan, if carried out, meets the requirements for compliance with 15A NCAC
2H .0217 adopted by the Environmental Management Commission.

This plan does not include commercial fertilizer. The farm should produce adequate plant
available nitrogen to satisfy the requirements of the crops listed above.
The applicator is cautioned that P and K may be over applied while meeting the N requirements.
In the future, regulations may require farmers in some parts of North Carolina to have a nutrient
management plan that addresses all nutrients. This plan only addresses nitrogen.
In interplanted fields ( i.e. small grain, etc, interseeded in bermuda), forage must be removed
through grazing, hay, and/or silage. Where grazing, plants should be grazed when they
reach a height of six to nine inches. Cattle should be removed when plants are grazed to a
height of four inches. In fields where small grain, etc, is to be removed for hay or silage, care
should be exercised not to let small grain reach maturity, especially late in the season (i.e.
April or May). Shading may result if small grain gets too high and this will definitely interfere
with stand of bermudagrass. This loss of stand will result in reduced yields and less nitrogen
being utilized. Rather than cutting small grain for hay or silage just before heading as is
the normal situation, you are encouraged to cut the small grain earlier. You may want to
consider harvesting hay or silage two to three times during the season, depending on the
time small grain is planted in the fall.
The ideal time to interplant small grain, etc, is late September or early October. Drilling is
recommended over broadcasting. Bermudagrass should be grazed or cut to a height of
about two inches before drilling for best results.

The waste utilization plan must contain provisions for periodic land application of sludge at
agronomic rates. The sludge will be nutrient rich and will require precautionary measures to
prevent over application of nutrients or other elements. Your production facility will produce
approximately 1632 pounds of plant available nitrogen per year and will accumulate in the lagoon
sludge based on the rates of accumulation listed above.
If you remove the sludge every 5 years, you will have approximately 8160 pounds of plant
available nitrogen to utilize. Assuming you apply this PAN to hybrid bermuda grass hayland at the
rate of 300 pounds of nitrogen per acre, you will need 27 acreas of land. If you apply the sludge
to corn at a rate of 125 pounds per acre, you will need 65.28 acres of land. Please note that these
are only estimates of the PAN produced and the land required to utilize that PAN. Actual values
may only be determined by sampling the sludge for plant available nitrogen content prior to application
Actual utilization rates will vary with soil type, crop, and realistic yield expectations for the specific
application fields designated for sludge application at time of removal.
APPLICATION OF WASTE BY IRRIGATION:
The irrigation application rate should not exceed the intake rate of the soil at the time of irrigation
such that runoff or ponding occurs. This rate is limited by initial soil moisture content, soil
structure, soil texture, water droplet size, and organic solids. The application amount should not
exceed the available water holding capacity of the soil at the time of irrigation nor should the
plant available nitrogen applied exceed the nitrogen needs of the crop.
If surface irrigation is the method of land application for this plan, it is the responsibility of the
producer and irrigation designer to ensure that an irrigation system is installed to properly
irrigate the acres shown in the preceding table. Failure to apply the recommended rates and
amounts of nitrogen shown in the tables may make this plan invalid.
*This is the maximum application amount allowed for the soil assuming the amount
of nitrogen allowed for the crop is not over applied. In many situations, the application
amount shown cannot be applied because of the nitrogen limitation. The maximum
application amount shown can be applied under optimum soil conditions.
Your facility is designed for >180 days of temporary storage and the temporary storage must
be removed on the average of once every 6 months. In no instance should the volume of the
waste stored in your structure be within the 25 year 24 hour storm storage or one foot of
freeboard except in the event of the 25 year 24 hour storm.
It is the responsibility of the producer and waste applicator to ensure that the spreader equipment
is operated properly to apply the correct rates to the acres shown in the tables. Failure to apply
the recommended rates and amounts of nitrogen shown in the tables may make this plan invalid.
Call your technical specialist after you receive the waste analysis report for assistance in
determining the amount of waste per acre and the proper application prior to applying the waste.

NUTRIENT UTILIZATION PLAN
REQUIRED SPECIFICATIONS
Animal waste shall not reach surface waters of the state by runoff, drift, manmade
conveyances, direct application, or direct discharge during operation or land application.
Any discharge of waste which reaches surface water is prohibited.
2 There must be documentation in the design folder that the producer either owns or has an
agreement for use of adequate land on which to properly apply the waste. If the producer
does not own adequate land to properly dispose of the waste, he/she shall provide
evidence of an agreement with a landowner, who is within a reasonable proximity,
allowing him/her the use of the land for waste application. It is the responsibility of the
owner of the waste production facility to secure an update of the Nutrient Utilization Plan
when there is a change in the operation, increase in the number of animals, method of
application, recieving crop type, or available land.
3 Animal waste shall be applied to meet, but not exceed, the nitrogen needs for realistic
crop yields based upon soil type, available moisture, historical data, climatic conditions,
and level of management, unless there are regulations that restrict the rate of applications
for other nutrients.
Animal waste shall be applied to land eroding less than 5 tons per acre per year. Waste
may be applied to land eroding at more than 5 tons per acre per year but less than 10 tons
per acre per year provided grass filter strips are installed where runoff leaves the field
(See USDA, NRCS Field Office Technical Guide Standard 393 - Filter Strips).
Odors can be reduced by injecting the waste or disking after waste application. Waste
should not be applied when there is danger of drift from the land application field.
6 When animal waste is to be applied on acres subject to flooding, waste will be soil
incorporated on conventionally tilled cropland. When waste is applied to conservation tilled
crops or grassland, the waste may be broadcast provided the application does not occur
during a season prone to flooding (See "Weather and Climate in North Carolina" for
guidance).
7 Liquid waste shall be applied at rates not to exceed the soil infiltration rate such that runoff
does not occur offsite or to surface waters and in a method which does not cause drift
from the site during application. No ponding should occur in order to control odor and
flies.
8 Animal waste shall not be applied to saturated soils, during rainfall events, or when the
surface is frozen.

NUTRIENT UTILIZATION PLAN
REQUIRED SPECIFICATIONS
9 Animal waste shall be applied on actively growing crops in such a manner that the crop is not
covered with waste to a depth that would inhibit growth. The potential for salt damage from
animal waste should also be considered.
10 Nutrients from waste shall not be applied in fall or winter for spring planted crops on soils with a
high potential for leaching. Waste/nutrient loading rates on these soils should be held to a
minimum and a suitable winter cover crop planted to take up released nutrients. Waste shall
not be applied more than 30 days prior to planting of the crop or forages breaking dormancy.
11 Any new swine facility sited on or after October 1, 1995 shall comply with the following: The
outer perimeter of the land area onto which waste is applied from a lagoon that is a component of
a swine farm shall be at least 50 feet from any residential property boundary and canal. Animal
waste, other than swine waste from facilities sited on or after October 1, 1995, shall not be
applied closer than 25 feet to perennial waters.
12 Animal waste shall not be applied closer than 100 feet to wells.
13 Animal waste shall not be applied closer than 200 feet of dwellings other than those owned by
the landowner.
14 Waste shall be applied in a manner not to reach other property and public right-of-ways.
15 Animal waste shall not be discharged into surface waters, drainageways, or wetlands by discharge
or by over -spraying. Animal waste may be applied to prior converted cropland provided the fields
have been approved as a land application site by a "technical specialist". Animal waste shall not
be applied on grassed waterways that discharge directly into water courses, and on other grassed
waterways, waste shall be applied at agronomic rates in a manner that causes no runoff or drift
from the site.
16 Domestic and industrial waste from washdown facilities, showers, toilets, sinks, etc., shall not be
discharged into the animal waste management system.

17 A protective cover of appropriate vegetation will be established on all disturbed areas (lagoon
embankments, berms, pipe runs, etc.). Areas shall be fenced, as necessary, to protect the
vegetation. Vegetation such as trees, shrubs, and other woody species, etc., are limited to areas
where considered appropriate. Lagoon areas should be kept mowed and accessible. Berms and
structures should be inspected regularly for evidence of erosion, leakage, or discharge.
18 If animal production at the facility is to be suspended or terminated, the owner is responsible for
obtaining and implementing a "closure plan" which will eliminate the possibility of an illegal
discharge, pollution and erosion.
19 Waste handling structures, piping, pumps, reels, etc., should be inspected on a regular basis to
prevent breakdowns, leaks and spills. A regular maintenance checklist should be kept on site.
Animal waste can be used
in _ _.taboo that Wtelt des-vege F ereps feF difect human _
consumption. However, if animal waste is used on crops for direct human consumption, it should
only be applied pre -plant with no further applications of animal waste during the crop season.
21 Highly visible markers shall be installed to mark the top and bottom elevations of the temporary
storage (pumping volume) of all waste treatment lagoons. Pumping shall be managed to
maintain the liquid level between the markers. A marker will be required to mark the maximum
storage volume for waste storage ponds.
22 Waste shall be tested within 60 days of utilization and soil shall be tested at least annually at crop
sites where waste products are applied. Nitrogen shall be the rate -determining nutrient, unless

In the event of an environmental release, there are four critical steps to follow:
1. Stop the flow— attempt to stop the source of the release.
• Try to keep the spill from becoming worse. If there is a way to stop the spill or minimize it becoming worse,
take those actions. These may be actions such as closing valves or shutting down a system, depending on
the source.
2. Contain the release.

• Approximately how much was released.
• Has the release left the property?
• Has the release encountered surface water, ground water, a drainage tile or intake, or other potentially
freshwater areas?
• Has the source of the release been stopped?
• Is the release contained?
An environmental spill is a discharge of one or more hazardous substances that adversely impact, or threaten to
adversely impact human health, welfare, or the environment and requires and immediate response.
Ensure all discovered environmental releases are reported immediately to Roeslein and Conine Farms.
Hazardous substance releases in which will reach waters of the state must be reported to the state within 8
hours, therefore, it's important to ensure Roeslein and Conine Farms are notified immediately.
Clean up the spill — If the spill was not caused by Roeslein, Conine Farms will be responsible forcleanup.
*Note: There is a passive overflow line from the water management wet well to the evaporation lagoon at 1.5'

Safety Practices for On -Farm Anaerobic Digestion Systems
1.0 INTRODUCTION
Several safety hazards exist when converting manure and organic residuals (non -farm
feedstock) into energy using anaerobic digestion (AD) technology. These hazards can cause
serious bodily harm and in some
circumstances, can be fatal. Common hazards I Figure 1: Safety signage on AD feed system
associated with AD systems include drowning,
electric shock, and noise exposure. However,
biogas and its constituents, many of which are
colorless and odorless, can unknowingly
expose operators and visitors to hazards such
as asphyxiation and burns due the flammable
nature of methane. Workers must take
proper precautions when handling and storing
organic material and managing the
production of electricity and combustible
gases.
The purpose of this document is to identify
the major hazards associated with an AD
facility and outline basic practices that will
help maintain a safe and successful working
environment. The intended audience for this
guide is owners and operators, and the guide
is not intended to replace safety training or
instruction, but rather enhance it.
2.0 SAFETY HAZARDS FOR
ANAEROBIC DIGESTION
The following sections identify major hazards that can exist with an AD facility. These include:
• General safety precautions
• Hazards associated with biogas
• Confined space entry
• Electrical system hazards
Figure 1 shows a feed hopper for an anaerobic digester with a dozen warning signs, including
fall, entanglement, and explosion potential.

Safety Practices for On -Farm Anaerobic Digestion Systems
2.1 GENERAL SAFETY PRECAUTIONS
The following sections describe general safety concerns associated with AD facilities.
2.1.1 Drowning
Liquid tanks and ponds for storage pose a drowning threat.
Whenever a drowning potential exists, ring buoys, ropes, or
ladders should be readily available for rescue purposes
(Occupational Safety and Health Administration [OSHA],
2002). The drowning risk is highest when employees are
servicing equipment located in digester or storage tanks.
Accidental drowning can occur when people unfamiliar with
the farm and manure handling system mistakenly enter
storage structures. Slipping on a synthetic liner or walking
on crusted manure storage are examples of situations that
can lead to accidental drowning. OSHA suggests posting
signs similar to the one shown in Figure 2 and erecting
fences around manure storage structures to reduce the
potential of an individual or animal unknowingly entering
one.

Spanish

Jrs_
If an individual is drowning, the first step should be to call 911, followed by a rescue attempt
using a life preserver, rope, or ladder. The presence of biogas—an asphyxiant that can cause a
person to pass out —can increase the potential of manure storage drowning. (Biogas hazards
are discussed in greater detail in Section 2.3.) Individuals attempting to rescue a drowning
individual should never enter a manure storage structure because they could also be overcome
by the poor air quality.
2.1.2 Fall protection
Serious injuries can result from falls of any distance. When possible, employees should perform
maintenance work from the ground. At most AD facilities, however, multiple elevated locations
are present. For example, equipment on the top of aboveground AD tanks are 10 to 25 feet off
the ground. According to the OSHA general industry standard any "time a worker is at a height
of four feet or more, the worker is at risk and needs to be protected" (OSHA, 2008A). Fall
protection, such as guardrails, a safety harness (also discussed in Section 2.2.4), and self -
retracting lifelines, should be used when an employee is above the 4-foot threshold (API, 2006).
The enclosed fixed ladder and guardrail system on the feedstock storage tank shown in Figure 3
complies with OSHA fall protection standards.

Safety Practices for On -Farm Anaerobic Digestion Systems
Another common example of a fall risk is shown in
Figure 4, where a ladder is leaned against a feedstock
storage tank. The two concerns with the situation
presented in Figure 4 are: (1) the tank height is
approximately 10 feet and (2) there are no securing
devices or slip resistant feet on the ladder, nor is
there a rope to secure the top. When ladders are
used to access elevated equipment, they should be
secured and supervised at all times. Once the ladder
is no longer needed, it should be removed.
2.1.3 Burns
Throughout an AD facility, pipes containing hot fluids
or exhaust gas can pose potential burn hazards.
Other potential sources of burns are heat exchangers,
boilers, pumps, or engine generators, where
temperatures can exceed 160°F. Simply rubbing up
against a heat exchanger or accidently placing a hand
on a hot pipe can result in serious burns. All
Figure 3: Permanent ladder and
guardrail on feedstock storage tank
employees and visitors to the AD facility should be cautioned not to touch any equipment or
pipelines.
When possible, hot surfaces should be identified as burn hazards, and all pipes should be
clearly labeled to indicate the contents,
Figure 4: Ladder leaning on feedstock storage
tank
flow direction, temperature, and pressure.
Insulation should be used to encase the
pipe and reduce the potential for
accidental burns. Figures 5 and 6 provide
examples of pipeline insulation and
labeling.
2.1.4 Entanglement hazard
Pumps, augers, impeller mixers, chains,
drive shafts, and other machinery pose
entanglement hazards due to pinch points
and other moving parts. In most AD
systems, the primary exposure to
entanglement is the unguarded driveshaft
3

Safety Practices for On -Farm Anaerobic Digestion Systems
of a pump. To reduce the entanglement risk,
all equipment safety guards should be in
place and individuals should tie back long
hair and avoid wearing loose -fitting clothing
and jewelry.
2.1.5 Feedstock and digestate spills
Figure 5: Insulated and labeled hot water
pipes
Feedstock (any organic material entering the eYi URN
digester) and digestate (any material exiting E
the digester) should be carefully transferred
and contained. In the event of a major ` I
feedstock or digestate spill, workers should
exercise caution when containing the f --
material. The first step should be to control pp��
the source causing the spill. Once this is'55'°`U°
achieved, workers should contain the spill by V
constructing temporary containment
structures around the affected area. Excavation equipment such as bulldozers and backhoes
should be readily available for this purpose. Isolating the spill reduces potential damage to
nearby buildings and contamination of surface
Figure 6: Biogas pipeline indicating waters and sensitive areas. After containing the
temperature and flow direction spill, the facility should notify the proper
authorities (as defined by state -specific permits), to
comply with all applicable local, state, and federal
regulations. For non -farm feedstocks, such as food
waste, the spill -reporting agency should be clearly
identified on all records related to the material,
including material safety data sheets (MSDS) and
manifest logs indicating the date, quantity, and
material (feedstock) brought onto the farm. The
final step in spill response is site cleanup and
restoration.
2.1.6 Mechanical failures
In the event of a mechanical failure, workers should reference the vendor manuals to
troubleshoot the issue. Vendor manuals for mechanical machinery should be organized and
included in the emergency action plan, which is discussed in Section 3.1. Only trained staff
4

Safety Practices for On -Farm Anaerobic Digestion Systems
should be permitted to repair digester equipment. Operators should use lockout/tagout
procedures (see Section 2.1.7) during all mechanical equipment repairs.
To avoid mechanical failures, the system operator, with support from the technology provider,
should develop a preventative maintenance manual for the site.
2.1.7 Lockout/ragout
According to OSHA standard 29 CFR 1910.147,
lockout/tagout refers to the specific "practices and
procedures to safeguard employees from the
unexpected energization or startup of machinery and
equipment, or the release of hazardous energy during
service or maintenance activities" (OSHA, 2007A).
Simply stated, before an employee services a piece of
electrical equipment, the power supply should be
turned off and the employee should place a padlock on
the power supply. The padlock serves to prevent
someone else from accidently re -energizing the
equipment being serviced. The lock should have a tag
on it identifying the individual who locked out the
Figure 7: Electrical panel turned off
and locked out
equipment. In Figure 7, one of the four electrical breakers shown is turned off (disengaged) and
locked out. Once a piece of equipment has been locked out, the only individual with the
authority to unlock that piece of equipment is the person who initially locked it out.
Employees should follow this practice every time they service any electrical or electrically
powered equipment. OSHA estimates that compliance with lockout/tagout procedures
prevents an estimated 120 fatalities and 50,000 injuries each year in the United States (2007A).
2.1.8 Ignition sources
Biogas generated during anaerobic digestion is flammable. Over the past couple of years,
several AD systems have been damaged or destroyed by fires fueled with biogas. While no
specific setbacks or standards have been established for biogas, facilities should observe
standards for similar systems. The National Fire Protection Association (NFPA) has established a
range of setback distances for liquid propane (LP) fuel based on storage capacity (2009). For LP
gas, the setback ranges from 10 feet for small storage devices (<500 gal water capacity) to 100
feet for large storage systems (>70,000 gal water capacity).

Safety Practices for On -Farm Anaerobic Digestion Systems
Smoking and open flames should be prohibited in
the general vicinity of the digester and a setback
distance of 25 to 50 feet is suggested for all
possible ignition sources to reduce the potential
for fire or explosion. Ignition sources can include
(but are not limited to) light switches, electric
motors, pilot flames, and cell phones. Facilities
should designate smoking areas at least 50 feet
from the digester system to ensure that visitors
and employees do not inadvertently create an
ignition source. Signs, like the one shown in Figure
8, should also be used to warn all individuals of
the explosion or fire risk associated with AD
systems.
The National Electric Code (NEC, 2005) dictates
that electrical wiring near combustible gas must
conform with the Class 1, Division 1 hazardous
location standard. Biogas is combustible, so the
Figure 8: Explosion potential sign
hazardous location standard should be applied to AD systems' electrical wiring.
For repairs requiring open flames or electric spark, ventilation should be provided such that
methane levels are maintained below a safe level, as discussed in Section 2.3.3.
Figure 9: Gen set enclosure with hearing
protection warning sign
2.1.9 Noise levels
Exposure to high levels of noise can
result in discomfort or short-term
hearing loss. In extreme cases, or if the
noise exposure occurs over a long
period of time, permanent hearing loss
can occur. The main source of high
noise levels is the engine generator set
(gen set). Actual decibel (dB) levels
produced at an AD facility will differ due
to varying acoustical settings, but a gen
set can produce between 100 —140 dB
(Fenton, 2011). The facility is required
to supply noise protection devices, such

Safety Practices for On -Farm Anaerobic Digestion Systems
as earplugs, to employees and visitors who are exposed to high noise levels (OSHA, 200813) (See
Table 1). Handheld decibel meters are widely available and provide an inexpensive method to
quickly determine the noise level. Also, OSHA encourages posting signs indicating "hearing
protection is required in this area." (See Figure 9).

2.2 CONFINED SPACE ENTRY
Constituents of biogas, including carbon dioxide, methane, and hydrogen sulfide, present the
potential for both asphyxiation and fire or explosion in confined spaces. It is important to
remember that even a few gallons of manure or other organic material in a tank or confined
space can pose a serious health risk under
Figure 10: Basic confined space warning sign
the right conditions. A recent example of
confined space entry fatality occurred in
July of 2010 when two farm employees died
while cleaning a storage tank similar to the
one shown in Figure 4 (Michigan
Department of Energy, Labor and Economic
Growth [MEDLEG]). Signs should be used to
alert employees and visitors when confined
space entry risks exist. Figure 10 shows an
example of a standard confined space
warning sign. The following background

information and guidelines are intended to promote a safe working environment when
confined space is involved.
7

Safety Practices for On -Farm Anaerobic Digestion Systems
2.2.1 Definition
"Confined space" is defined by OSHA as "having a limited or restricted means of entry or exit;
large enough to bodily enter and perform tasks; and lastly, not designed for continuous
occupancy." Currently, state -by -state standards vary for permit -required confined spaces
training for agriculture; however, confined spaces are widely recognized as a common hazard.
Confined spaces include, but are not limited to, tanks, pits, silos, underground vaults, storage
bins, and manholes (MDELEG, 2010).
2.2.2 Confined space training, certification, and rescue plan
Employees associated with AD systems or who manage organic residuals MUST be trained in
confined space entry to maintain a safe working environment (Gould, 2010). Several cases have
resulted in fatalities due to a lack of understanding of the hazards associated with confined
spaces. As discussed earlier, two farm employees died when they were overcome by a lack of
oxygen while cleaning a feedstock storage tank (MDELEG, 2010). The employees were power
washing a tank that contained only 6 to 8 inches of molasses residue, which had sat unused for
five to six months. By conducting basic employee education and strictly adhering to OSHA
confined space entry guidelines, facilities can provide a safe working environment for farm
employees.
Currently, OSHA does not require farms to offer
specific training for confined space entry;
however, it is the employer's responsibility to
educate employees in order to maintain a safe
working environment. When entering a confined
space, the "buddy system" should be used, in
which any person entering a confined space is
monitored from a safe distance by a second
person. The employee entering the confined
space must wear a harness attached to a
retraction device that the second employee can
activate to pull the individual to safety in an
emergency.
The facility should develop a rescue plan for
emergency confined space entry situations. This
plan should describe the use of the safety
Figure 11: Handheld multi -gas detectors
a
pq

equipment in emergency situations, the actions to be taken, and the personnel responsible for
each action. The plan may also include training and certification information.
RI

Safety Practices for On -Farm Anaerobic Digestion Systems
2.2.3 Inspect atmosphere prior to entry
Before entering a confined space, a worker must test the atmosphere inside the space, as
required by OSHA general industry standard 1910.146 (1998). The person can perform this
testing using a handheld multi -gas detector capable of detecting oxygen, carbon monoxide,
hydrogen sulfide, and lower explosive limits (LEL) levels. Several models of multi -gas detectors
are shown in Figure 11. When testing the atmosphere within a confined space, the employee
should remain outside in a safe location. Many multi -gas detectors are equipped with an
extension hose for this purpose.
In compliance with standards (OSHA, 1998), the employee should test for the following:
Oxygen level: above 19.5 percent by volume air
2. Methane: below 5 percent by volume of air
3. Hydrogen sulfide level: below 20 parts per million (ppm)
If any of the above conditions are not met, the atmosphere is deemed hazardous and should
not be entered by any personnel until forced ventilation has eliminated the hazardous
conditions. During entry, continuous ventilation with an explosion -proof blower will ensure that
fresh air is displacing any hazardous air that may be trapped in the confined space. Workers
must maintain and calibrate this equipment
according to the manufacturer's
recommendation in order to effectively monitor
atmospheric conditions.
2.2.4 Safety equipment
When entering a confined space, an employee
should wear a safety harness attached to a
winch or pulley outside of the pit. Examples of
safety harnesses and a winch are shown in
Figure 12. This safety precaution, allows a
coworker to assist a trapped employee without
having to enter the space in the event of an
emergency.
A self-contained breathing apparatus (SCBA)
should be used only in emergency situations.
Figure 12: Safety harnesses, ropes, and a
chain fall at an AD facility

Safety Practices for On -Farm Anaerobic Digestion Systems
Figure 13 shows a basic backpack -style SCBA with fitted facemask. Any employee using a SCBA
must be properly trained and fitted for using the equipment. For an individual to become
certified in confined space entry, they should consult the
State approved OSHA administration.
2.3 HAZARDS ASSOCIATED WITH BIOGAS
AD biogas is composed of three main constituents:
methane, hydrogen sulfide, and carbon dioxide. Each of
these gases can be dangerous under certain circumstances.
Common hazards associated with biogas include
asphyxiation and fire or explosion potential.
Overall, it is always a good idea to test the atmosphere
when biogas may be present as well as maintain proper
ventilation. Workers can use a handheld multi -gas detector,
similar to one of those shown in Figure 11, to determine if
hazardous levels of biogas are present. Low-cost detectors
will simply identify dangerous level of biogas, while higher
end detectors can report specific concentrations of the
primary biogas components.
2.3.1 Asphyxiants
Gases that prevent the uptake of oxygen into human cells
Figure 13: Self-contained
breathing apparatus
Irnage fro rnhttlX;' ,-r::::.enriSUPPI .corn/
are referred to as asphyxiants. There are two categories of
asphyxiants: simple and chemical. A simple asphyxiant displaces oxygen, and chemical
asphyxiants "reduce the body's ability to absorb, transport, or utilize inhaled oxygen.
Asphyxiants are often active at very low concentrations (a few ppm)" (Lawrence Berkeley
National Laboratory, 2008). Asphyxiant gases are present wherever there is storage of an
organic material; therefore, manure pits or any other areas for organic material storage
become potentially dangerous. Following are the various asphyxiants that are typical
constituents of biogas.
• Simple asphyxiants —carbon dioxide and methane
• Chemical asphyxiants — ammonia and hydrogen sulfide
10

Safety Practices for On -Farm Anaerobic Digestion Systems
2.3.2 Immediately dangerous to life and health
Within confined spaces and other covered areas, the potential exists for atmospheric
concentrations to develop that become immediately dangerous to life and health (IDLH). An
IDLH condition can be defined as an atmospheric concentration of any toxic, corrosive, or
asphyxiant substance (simple or chemical) that "poses an immediate threat to life or would
cause irreversible or delayed adverse health effects or would interfere with an individual's
ability to escape from a dangerous atmosphere" (OSHA, 2008C). Following are the main IDLH
concerns when handling the production of biogas (Center
for Disease Control and Prevention, 1995).
• Oxygen deficiency — less than 19.5 percent by
volume air
• Hydrogen sulfide — more than 100 ppm
• Ammonia — more than 300 ppm
• Carbon dioxide — more than 40,000 ppm
Signs similar to the one shown in Figure 14 should be used
to alert employees and visitors of the potential for IDLH
conditions. Areas prone to these conditions include
structures housing the gen set or boiler, below grade pump
chambers, and biogas storage devices.

ENTER PITONLY WITH:
• SELF-CONTAINED AIR SUPPLY
• VENTILATION
• RESCUE HARNESS, MECHANICAL
LIFT, STAND-BY PERSON
A simple and convenient way to ensure the safety of an area's atmosphere is by installing a
wall -mounted sensor that can detect hazardous gases (e.g., methane, LEL, hydrogen sulfide,
carbon monoxide). In the event that a hazardous gas sensor is triggered, the emergency action
plan (see Section 3) should be implemented.
2.3.3 Explosion potential
Methane, the main component of biogas, is flammable
when it mixes with air. Upper and lower explosive limits
(LEL) are established to provide an identifiable range of
concentrations that will produce a flash fire when an
ignition source is presented. The LEL is often referred to as
a flammable limit. For methane, the lower and upper
explosive limit is 5 percent and 15 percent by volume of
air, respectively (Linde Gas LLC, 1995).

Safety Practices for On -Farm Anaerobic Digestion Systems
2.4 ELECTRICAL SYSTEM HAZARDS
The generation of large quantities of electricity at an AD facility creates electrical hazards, most
of which can be found near the gen set, transformer, and electrical panels. The only personnel
with the authority to service and repair electrical systems are licensed electricians. In addition,
the facility should post signs identifying general electrical hazards near the electrical generation
system (see Figure 15 for an example of basic signage).
2.4.1 High voltage
Any electrical source above 600 volts is
considered high voltage (NEC, 2005). Typically,
transmission lines from the transformer are the
source of the highest voltage on a farm. A
transformer is a piece of machinery used to
increase the voltage, allowing for more efficient
transport of the electricity. When dealing with
such high voltage, the main hazard is contact
with exposed leads, which could be fatal. Figure
16 shows exposed lead transformers commonly
used on utility poles. Ground -mounted
transformers used on farms and at AD facilities
are typically enclosed like the one shown in
Figure 16: Standard electrical
transformer with exposed leads
Figure 17. Enclosed transformers should remain sealed
Figure 17: Enclosed electrical and locked at all times, and only a licensed electrician
transformer should perform transformer maintenance.
V; 2.4.2 Low voltage
All electrical sources less than 600 volts are considered
-----E n low voltage (NEC, 2005). Typically, switches,
- controllers, fuses, breakers, wall outlets, and electrical
panels are considered low -voltage devices. One major
hazard associated with electrical panels is arcing, which
" occurs when electricity from an energized source
jumps a gap of air and discharges into an adjacent conductive surface, typically metal. If an
individual happens to be in the pathway of the arc, they can be seriously burned or killed. Cover
plates are used to contain arcing by shielding the employee from any potential harm.
Therefore, the facility should ensure that the proper cover plates are intact and correctly in
place on the panel or outlet.
12

Safety Practices for On -Farm Anaerobic Digestion Systems
2.4.3 Electrical fires
In the event of an electrical fire, the person fighting the fire should use an ABC classified multi-
purpose fire extinguisher rather than a water -based fire extinguisher, which could result in
electrocution. If possible, the electricity should be shut off to the facility before fighting the fire.
The facility should train operators to identify the difference between electrical fires and
ordinary combustible fires (Wallenwine, 2011).
3.0 MAINTAINING A SAFE WORKING ENVIRONMENT
AD facilities can provide a safe working environment, as long as proper safety measures are
taken. The following sections present recommended steps for maintaining a safe working
environment at AD facilities, adapted from the self -assessment guide prepared by Nellie Brown
(2007), titled "Conducting a Safety Walk-through on a Farm: Hazards of the Manure Handling
System, Anaerobic Digester, and Biogas Handling System" and the emergency action plan
requirements of the National Pollution Discharge Elimination System (NPDES) program.
3.1 EMERGENCY ACTION PLAN
In most states, AD facilities are required to have emergency action plans (EAP) as part of their
NPDES permits. A major objective of an EAP is to develop response protocols to specific
emergencies so that if an accident occurs the facility will conduct the appropriate actions in the
correct sequence. As a general recommendation, each situation should be broken down into
the following components.
Assess the extent of damage in the following order:
a. Human health
b. Environmental health
C. Mechanical integrity
2. Correct the problem immediately if possible.
3. Contact the appropriate agencies and personnel to resolve the problem.
The contents of an EAP should be well organized in a binder or an electronic file and distributed
to all employees so that they are informed of the proper safety protocols. The facility should
provide local emergency departments with a copy of the EAP and invite them for a tour of the
operation so they can become familiar with the facility. Also, the facility should post a copy in a
highly visible area where visitors enter the facility.
13

Safety Practices for On -Farm Anaerobic Digestion Systems
To maintain an effective EAP, the facility should perform an annual review of the document to
keep it up to date. Conducting annual training sessions will ensure that employees have a basic
understanding of the EAP. The following sections present the recommended content to be
included in an EAP.
3.1.1 Directions to AD facility
Often, the AD facility is not clearly visible from the main road, especially if it is located in an
agricultural setting. Therefore, detailed driving directions from the closest major road,
intersection, or town to the physical location of the AD facility should be included in the EAP.
3.1.2 Contact information
The EAP should provide a list of emergency and non -emergency contacts, including the job title
and cell phone number of each person. Recommended contacts are:
• Farm or AD owner
• AD operators
• Emergency and nonemergency responders
o Fire department
o Poison control
o Law enforcement
o Hospital
• Electric and gas utilities
• Contractors
o Electrical
o Excavation
o Mechanical
• State health and safety officials
Contact information should identify the appropriate after-hours emergency contact
information as well. The contact list should be posted in multiple locations throughout the AD
facility and farm so that in the event of an emergency, there is quick and easy access to this
information. It is important that the contact list be updated routinely to make sure all
information is current.
14

Safety Practices for On -Farm Anaerobic Digestion Systems
In many rural locations, calling 911 may not be the best method for reaching emergency
responders. On an annual basis, the AD operator or owner should host a site tour with the local
fire, ambulance, and sheriff departments. The purpose of this tour would be to familiarize
emergency responders with the site and system, as well as identify the most direct contact
method in the event of an emergency.
3.1.3 Site map
The EAP should include a detailed site map that identifies and labels relevant structures and
major equipment (e.g., flare, gen set, boiler) at the AD facility, as well as the location of
emergency equipment. It should also clearly identify the locations of biogas supply shutoff
valves and the primary electrical disconnect and control panel.
3.1.4 State and local health and safety requirements
The EAP should include the federal and state health and safety regulations for the facility, as
well as all OSHA documents, guidelines, and certifications, including confined space entry
training documents. In addition, MSDS for non -farm feedstock and any chemical or biological
additives should be included in the EAP and posted at the facility so that employees can have
quick access to the information.
3.1.5 Equipment vendor manuals
The EAP should include the vendor manuals for all equipment at the AD facility. These materials
should be well organized so that in the case of a mechanical failure, an operator can locate and
reference a specific vendor manual quickly and easily.
3.2 SAFETY AND EMERGENCY EQUIPMENT
The following sections list recommended supplies and equipment an AD facility should have
available for normal daily operation or in the event of an emergency. The list is divided into
supplies and equipment to be maintained on site, so employees can access it within minutes,
and equipment that should be locally available and could be delivered to the site within a few
hours. A logbook of equipment inspections and expiration dates and the equipment manuals
should be located with the safety equipment.
3.2.1 Anaerobic digester facility (onsite)
• Personal protective equipment
o Gloves
o Safety glasses
15

Safety Practices for On -Farm Anaerobic Digestion Systems
o Hearing protection
o SCBA (provided employees are properly trained and fitted for using the
equipment).
• First aid kit
• Fire extinguishers (ABC)
• Explosion -proof instruments (e.g., flashlight, ventilation blower, hand tools)
• Rigging equipment for rescue of a person
o Hoist, winch, or pulley
o Safety harness
• Multi -gas detector with extension hose
• Ring buoy
• Shovel
3.2.2 Locally (able to be onsite within a few hours)
• Excavation equipment (e.g., bull dozer, backhoe, excavator)
• SCBA and trained individual
3.2.3 Baseline environmental conditions
During startup and for the first 6 to 12 months of use, operators should collect operational
parameters and air quality measurements around the AD facility on a weekly basis to establish
baseline/normal operating conditions. Basic operational parameters should include pressure
and temperature readings on pipelines where gauges are installed. Using a handheld multi -gas
meter, employees should check the air quality inside all structures or rooms, along with the
conditions in below -grade pump chambers, near the base of digester tanks, and along biogas
pipelines. At a minimum, the concentration levels of hydrogen sulfide, carbon monoxide, and
methane should be measured and recorded. By establishing baseline operating conditions, the
AD operator has a point of reference for troubleshooting operational problems and
determining when hazardous conditions are developing or already exist.
16

Safety Practices for On -Farm Anaerobic Digestion Systems
3.3 ELECTRICAL
The following section provides common practices to help maintain safety by reducing the
potential for electrical hazards that may occur at an AD facility.
3.3.1 Daily inspections
The AD facility should instruct operators to perform
daily inspections of the electrical system. This
inspection should include, but not be limited to, the
following:
• Conduit connections to panels
• Panel cover integrity
• Conduit integrity
• Exposed and damaged wires
• Corrosion of wires
• Signs of electrical overheating
If there is any sign of the aforementioned problems,
operators should contact the site manager or a
licensed electrician to resolve the issue. Figure 18
shows a corroded electrical control panel that an
Figure 18: Corrosion on an electrical
control panel
operator should identify for repair during daily inspections. The operator should not attempt to
fix the problem unless he or she is the appointed licensed electrician for the facility.
3.3.2 Switches, controllers, fuses, and breaker panels
Electrical panels should not be obstructed by any object that would impede the accessibility of
the panel itself. For example, temporarily placing a 55-gallon drum below a circuit breaker or
installing a pump below a control panel would impede accessibility. Moreover, electrical panels
should always be visible so that emergency responders can locate them easily. This becomes
imperative when an electrician unfamiliar with the facility needs to turn off the power quickly
in an emergency situation.
All electrical panels should be well labeled and include an accurate, up-to-date copy of the
wiring diagram (Wallenwine, 2011). Additional copies of the wiring diagram should be
maintained off site and digitally in the event that a copy is lost, damaged, or destroyed. The
facility should check the local electrical code to determine the clearance required around the
electrical panel.
17

Safety Practices for On -Farm Anaerobic Digestion Systems
3.3.3 Roles of operators
An operator inspects and observes any defective electrical problems but does not perform any
electrical maintenance. A licensed electrical engineer appointed by the AD facility is responsible
for maintenance and repair of electrical problems.
3.3.4 Visitors on site
Unattended facilities associated with the AD system should be locked to limit risk to individuals
unfamiliar with the surroundings and to ensure that the system continues to operate efficiently.
Employees familiar with the AD system should escort visitors at all times. Visitors to an AD
facility are not to operate any switches, controllers, or other electrical functions, including light
switches.
3.4 PERSONAL PROTECTIVE EQUIPMENT
Personnel at an AD facility should be provided with proper -fitting personal protective
equipment (PPE). The employer is responsible for communicating and educating the employees
on the proper use of PPE (OSHA, 20076). At a minimum, OSHA recommends protective gloves,
splash -proof goggles, hearing protection, and steel toe shoes for employees associated with the
digester system. For visitors to the facility, safety glasses and hearing protection should be
available and worn while on site.
3.5 ACCIDENT PREVENTION SIGNS AND TAGS
Accident prevention signs and tags should be visible at all times when work is being performed
where a hazard may be present and should be removed or covered promptly when the hazards
no longer exist. Also, caution signs should be designed to be understood by non-English
speakers. The EAP should include resources documenting where proper signs or tags can be
obtained for potential facility hazards. A variety of OSHA -approved accident prevention signs
are shown in Figure 19.

3.6 PERSONNEL TRAINING REQUIREMENTS
Annually, the facility should review the EAP with all employees associated with the AD system
and new hires should go through safety and system operation training before being permitted
to work at the AD facility. In addition, owners of systems should be aware of OSHA
requirements and comply with employee training requirements.
4.0 CONCLUSION
Anaerobic digestion provides a real opportunity to address farm -related environmental
concerns, generate renewable energy, and diversify farm products. It is important to realize,
however, that AD systems pose unique challenges and safety risks not experienced on typical
farms. These risks can be mitigated by practical measures, including educating employees about
the risks associated with the system, implementing strict safety procedures, and having a
detailed and up to date EAP that employees are familiar with. Ensuring a safe environment
around the AD facility will protect employees and visitors while enhancing the overall
performance of the digester.
