Liberation Capital BG Winston-Salem LLC/Carolinas Resource Recovery Odor and Vector
Control Plan

Odor and Vector control at the CRR Winston-Salem facility is accomplished by the following
means:

1. Both indoor and outdoor vessels containing grease trap waste liquids are vented to a
5,000 scfm chemical scrubber (scrubber) to control fugitive odor and the attraction of
vectors.
2. Plant Operators shall drain, clean and replace scrubber recirculating water on a daily
basis, M-F. Whenever possible, scrubber shall be cleaned and returned to service
before 6 AM.
3. Plant Operators shall check and confirm feed of chlorine dioxide to scrubber a minimum
of twice each shift and record chlorine dioxide pump speed on Odor Control Log Sheet.
Monthly Odor Control Log Sheet shall be posted in the lab with copies kept in the site
office. Admin shall also check the chlorine dioxide feed to the scrubber at the
beginning, middle and end of each workday and record chlorine dioxide inventory on
the Odor Control Log Sheet. Operators and Admin will adjust chlorine dioxide feedrate
as may be necessary based on production and atmospheric conditions, recording any
adjustments to chlorine dioxide feedrate on the Odor Control Log Sheet.
4. Truck unloading is via hose connections so that raw grease trap waste is not aerated
during unloading and spills and odor release are minimized. Any unloading spills are
immediately washed into the unloading area trench and into the grease trap waste
receiving bin.
5. Except when the unloading pad is being cleaned, the end of the unloading pad trench
will be sealed to prevent winds, if present, from drawing air/odor from the process
building.
6. Where possible, incoming trucks containing grease trap waste are unloaded via pump,
vs. pressurization, to minimize the potential for odor generation from truck tank
pressure relief/venting.
7. An odor neutralizer/masking agent fogging system is employed in the truck unloading
area, along the process building roofline and inside the process building. Plant
Operators shall check the foggers each shift for proper operation and note such on Odor
Control Log Sheet.
8. Admin shall check and record odor neutralizer levels in each fogger M-F and record
levels and inventory on Odor Control Log Sheet. Admin shall make periodic inspections
of site perimeter to confirm odor control systems are functioning normally and report
any abnormalities to Plant Manager, Operator on duty and Director of O&M.

Atmospheric conditions, including wind direction and speed shall be recorded by Admin
on Odor Control Log Sheet.
9. Grease trap waste component solid waste containers (trash and "food solids") are
covered when not in active use, and emptied regularly as containers become full.
10. Truck unloading and solid waste roll-off container pads drain to the grease trap waste
receiving bin or wastewater neutralization tank inside the building, to prevent GTW or
filtrate from pooling and providing a breeding site for flies or mosquitoes.
11. CRR utilizes good housekeeping practices, such as daily hot-pressure washing of
loading/unloading pads and floor surfaces to prevent the build-up of spilled and
odorous materials.
12. Doors on CRR's process building are closed when the facility is not in operation to
restrict building access by vectors.
