Swine Farm Waste Management — Odor Control Checklist
Permit No.: 82-159
Da : 3/18/20
INSTRUCTIONS FOR USE Owner Signatur `
♦ Odor Control Checklist is required by General Statute 143-215.10C(e)(1)
♦ Check any/all the BMPs you will implement on this facility. Items checkedlselected become a requirement of the CAWMP.
♦ Items in bold or pre -selected are required.
♦ Add any site -specific details related to the selected BMPs
♦ Include any other odor control measures not listed
♦ NOTE: Not all BMPs may be cost-effective for every facility. Evaluate each BMP prior to selecting for your facility.
Cause/Source
BMP Option to Minimize Odor
Comments Site Specific Practices
FARMSTEAD
♦ Swine Production
® Maintain vegetative or wooded buffers at or
• Traps dust and gases, provides dilution
near property boundary
and visual screening
• May require third party input/approval
♦ Improper drainage
® Grade and landscape so water drains away
• Reduce odors and vectors that occur
from facilities and prevent ponding
with stagnant conditions
® Maintain farm access roads and prevent traffic
• Prevents spillage during transport and
in waste application area
tracking of waste onto public roads
❑ Other BMPs — please describe
MORTALITY MANAGEMENT
♦ Carcass ® Dispose of mortality using method approved
Decomposition by NCDA&CS State Veterinarian. Manage
According to CAWMP (Mortality Management
Checklist) and permit(s).
❑ Put carcasses in refrigerated (or freezer) dead
boxes within 24 hours for short-term mortality
storage.
♦ Incomplete Incineration ❑ Use incinerators with secondary burners for
complete combustion.
❑ OtherBMPs— please describe
• Required by statute and permit
• May require third party input/approval
• Reduce odors by complete incineration

• Will move with other manure via pits
• Where applicable
• Aids in animal cleanliness
• Aids in animal cleanliness
• Solid floor/bedding systems

Permit No.: 82-159
Cause/Source BMP Option to Minimize Odor Comments Site Specific Practices
HOUSE / BARN —VENTILATION
♦ Dust ® Clean fans regularly—specifyfrequency
♦ Volatile/odorous gases ® Efficient air movement
® Install temperature and humidity sensors to
control ventilation
❑ Treat barn exhaust • Examples: biofilters, wet scrubbing, windbreaks
• May reduce ventilation rate depending on method
❑ OtherBMPs— please describe
HOUSE / BARN — FEED
♦ Dust ❑ Install feed covers
♦ Adsorbed Gases ® Keep outdoor feed storage covered except
• Required by rule 15A NCAC 02D .1802
When necessary to add/remove feed
❑ Minimize free -fall height of dry feed
❑ Install feed delivery downspout extenders
to the feed covers
® Remove spoiled/unusable feed on regular basis
❑ Feed pellets instead of dry meal
• May require third party input/approval
❑ Use feed additives
• May require third party input/approval
♦ Ammonia ❑ Use feed -reduced crude protein diet
• May require third party input/approval
❑ OtherBMPs— please describe
HOUSE / BARN — GENERAL
♦ Dust ® Install temperature and humidity sensors • Maintain relative humidity at 40 to 65%
♦ Odorous Gases to control ventilation
❑ Use ultraviolet light to treat indoor air
❑ Use indoor or outdoor electrostatic space • Can be used to treat exhaust air
charge system
❑ Other BMPs — please describe

Cause/Source BMP Option to Minimize Odor Comments Site Specific Practices
LAGOON / WASTE STORAGE STRUCTURE
♦ Volatile Gases ® Maintain proper lagoon volume
❑ Minimize free -fall height of waste from
discharge pipe to lagoon surface
❑ Extend discharge point of pipe to below lagoon
liquid level
❑ Maintain proper surface area -to -volume ratio
❑ Use correct lagoon start-up procedures
❑ Aerate for odor control
® Manage sludge levels based on annual sludge
survey as required by permit
® Keep spilled feed or foreign debris out of lagoon
to prevent excess sludge accumulation
❑ Install/use solids separation system
❑ Use proven biological or chemical additives
❑ Use permeable lagoon covers (not a digester)
❑ Use impermeable lagoon cover or
anaerobic digester
❑ OtherBMPs—please describe
LAND APPLICATION
♦ Odorous gases ® Perform land application in accordance with
CAWMP
♦ Wind drift ® Pump intake near lagoon surface
❑ Pump from second stage lagoon
❑ Follow good neighbor policy
❑ Operate at minimum recommended pressure
❑ Increase setbacks beyond those required by
statute, rule, or permit
Swine AMOC
• Sufficient liquid volume/depth is required
for proper anaerobic treatment
• Use caution not to scour or damage lagoon liner
• Monitor for any increase in rate of solids accumulation
. Methane can be flared if not utilized
• Required by rule 15A NCAC 02D .1802
-Avoid application on known weekends,
special days, or holidays/eves if possible

LAND APPLICATION (CONTINUED)
® Apply during favorable wind conditions,
(especially for traveling guns or impact
sprinklers)
® When practical, apply waste on sunny days
rather than cool, overcast days
❑ When possible, apply waste mid -morning to
late -afternoon
❑ For traveling guns, use taper -ring or taper -bore
nozzles
❑ For traveling guns, use largest -available nozzle
that provides acceptable application uniformity
❑ Replace impact sprinklers with low -drift nozzles
on center pivots and linear move systems.
❑ Use hose -drag system
❑ Use injection method for waste application
❑ OtherBMPs—please describe
SLUDGE DISPOSAL
♦ Odorous gases ❑ Transport sludge in covered vehicles or tankers
❑ Apply in thin, uniform layers
❑ Incorporate land -applied sludge as soon as
practical after application, and in accordance
with permit.
❑ Use injection method for sludge application
❑ Dewater sludge prior to application
❑ Use alternatives to land application, such as
compost, gasification, energy generation, etc.
❑ OtherBMPs—please describe
• Recommend checking predicted average hourly
wind speed within 24 hours prior to
anticipated start
• Allows for vertical dissipation of odor
• Allows for better vertical dissipation of odor
• Less odor and drift than ring nozzles
• Speeds drying and prevents ponding
• Required within 48 hours or prior to next rain event,
whichever is first, for conventionally tilled
bare soils
