Best Management Practices
A. SECONDARY CONTAINMENT SYSTEMS
All of the processing areas, above ground storage tanks, loading/unloading areas, and the
Flammable Drum Storage sheds have secondary containment. The specifics of each containment area are
addressed below:
A.1. Main Plant Area
All of the above ground storage tanks in the main plant are located in a common secondary
containment area with the exception of Tank S-28. The secondary containment for the main plant is
created through the use of concrete walls/curbs, concrete floors and asphalt/concrete aprons sloped toward
the interior of the main plant. These walls/curbs and sloped aprons provide containment for the entire,
main plant. Based on an instrument survey of the main plant, the containment volume is estimated to be
approximately 113,800 gallons. Note the largest single tank capacity in the main plant is 30,000 gallons
(Tank S-31).
Normally, any spilled liquid is collected in the trench drains located throughout the main plant
and conveyed by gravity to the sewer lift station located in the southeast quadrant of the main plant's
containment area. Rainwater that enters the secondary containment area is also collected in the trench
drains, and conveyed to the sewer lift station and the pretreatment system before entering the sanitary
sewer system. The majority of the rainwater that falls on the main plant is captured by roof drains and
discharged outside of the secondary containment area.
The only tank in the main plat area that is not contained in the common secondary containment
area is S-28, which is a 5,000-gallon acid tank. Tank S-28 has a separate concrete secondary containment
area. This containment area is adequately sized to contain a release of the full contents of tank S-28 (plus
10%), plus precipitation. Storm water is released from this area via pumping into the main plant's process
sewer system.
A.2. Main Tank Farm Area
All of the tanks in the tank farm area are located in a common secondary containment area. The
secondary containment area is constructed of concrete floors and walls. This containment area is
adequately sized to contain a release of the full contents of the largest tank (Plus 10%), plus precipitation.
No drains are located in this secondary containment area. The secondary containment area for these tanks
is equipped with a sump and pump to remove rainwater and spilled materials. All spilled material or
rainwater is pumped to the Main Plant's process sewer system.
BMP's section revised 10'12/11
Updated: February 2022
tDOCUMENI TITLE] j Document subtitle }
�...

A.3. Ester Tank Farm
A11 the tanks in the Ester Tank Farm are located in a common secondary containment area. The
secondary containment area is constructed of concrete floors and walls. This containment area is
adequately sized to contain a release of the largest tank (plus 10%), plus precipitation. The transfer
pump for the tanks in this area is located within the secondary containment structure. No drains are
located in the secondary containment structure. Rainwater and spilled materials are removed via a
sump pump that discharges into the Main Plant's process sewer system.
A.4. Rail Car Loading/Unloading Area
The rail car tank transfer station (next to the Main Tank Farm) is designed with a secondary
containment system to prevent leaks and drips from the rail cars from entering the environment,
However, the containment area is unable to control a major release that could occur from a faulty
valve or full tank car failure nor hold the contents of the largest capacity rail car (29,000 gallons
maximum) that services the area. The secondary containment pads, located partly beneath the rail
tank car being loaded or unloaded, is one concrete and the second is plastic with both sloping toward
a sumps located adjacent to the tracks. The transfer connection (valves) on the railcar is centered over
the concrete pad during transfer operations so that should a spill occur at the valve, it would drain to
the sump. The sump is provided with a pump to transfer the spilled material into the Main Plant's
process sewer system.
A.5. Alcohol Tank Farm
All the tanks in the Alcohol Tank Farm are located in a common secondary containment area. The
secondary containment area is constructed of concrete floors and walls. The containment area is
sufficiently sized to contain the required 110 percent of the largest tank located within it plus
precipitation. The transfer pumps for the tanks in this area are located within the secondary
containment structure. The secondary containment area is equipped with a sump and pump to remove
rainwater and spilled materials. No drains are located in the secondary containment area for the
tanks. All spilled material or rainwater is pumped to the Main Plant's process sewer system.
A.b. Flammable Drum Storage Area
The Flammable Drum Storage is in outdoor storage containers that hold 4 drums each with secondary
containment capacity to hold over 1 drums if a leak occurs. The storage containers can be transported
by forklift to the plant if need arises. The drums are transferred to the plant as needed. Flammable
drums can also be stored in the lab storage area and the plant area. Both areas have secondary
containment sufficient to handle the capacity of the largest container.
A.7 N Tank Farm
All the tanks in the N Tank Farm are located within a common and concrete secondary
containment area that should prevent a release to the environment from a spill in this area. The
containment is constructed of concrete floors and walls with an area sufficiently sized to contain the
required 110 percent of the largest tank located within it plus precipitation. Storm water or spills from
inside this secondary containment area flow to a sump and are pumped to the Main Plant's process sewer
system. BMF's section revised 04/21116

A.B. Inspection of Secondary Containment Systems
The facility's secondary containment systems are formally inspected weekly. The inspection
includes examination of the containment structure's integrity. Any potential failure points in the
containment structures are repaired. The Environmental Manager or designee maintains completed forms.
B. BULK STORAGE TANK INSPECTION AND INVENTORY CONTROL
Inventory levels of bulk tanks are generally taken three times per week. Personnel performing the
inventory examine the tanks and report any suspected leaks. Further, the inventory is compared with the
previous inventory and any abnormal changes are investigated.
C. FACILITY TRANSFER OPERATIONS, PUMPING, AND IN -PLANT PROCESS
All in -plant transfers are manned operations. All transfer pumps in the main plant are visible and
are monitored during transfer operations. The transfer pumps for the Main Tank Farm, Alcohol Tank
Farm, and Ester Tank Farm are located within the secondary containment area for the respective tank
farm, to determine if liquids can be transferred between tanks, personnel measure the receiving tank and
verify the transferred material will fit.
All transfer piping at the facility is either exposed (above ground) for visual inspection or is
contained in a steel plate fabricated pipe trench (top of trench is parallel with existing grade). Normal
vehicular traffic does not pose a direct threat to above ground piping.
D. FACILITY TANK CAR AND TANK TRUCK LOADINGIUNLOADING
Transfers of materials to and from outside sources (tank wagons and railcars) occur at two locations at the
Chemol facility;
1) Tank trucks load and unload to the west of the main plant and
2) Rail cars park in the rail car unloading area located west of the main tank farm.
D.1. Railcar Unloading
The rail car unloading area has a single connection point for unloading operations, which precludes the
opportunity for confusion in piping. The rail car unloading area services tanks in the tank farm area (TF -
I through TF-12), which are equipped with local audible
high-level alarms. The rail unloading area is designed with a secondary containment system to
prevent leaks and drips from the rail cars from entering the environment; however, the containment
area is unable to control a major release occurring from a faulty valve or full tank car failure.
Currently, railcars are only used to receive nonhazardous raw materials that are typicaly solid at
ambient temperatures. They are only heated when the railcar is positioned over the containment
structure. This precludes the; possibility material could leak from a railcar not positioned over the
containment structure. See Section A.4 for additional information on the secondary containment at
this location. BMF's section revised 09121121
Updated: February 2022
[UOCUMiwfVl-TITtEJ 1 ;Documert subtidel

D.2. Tank Truck Loading and Unloading
The tank truck loading/unloading area is located west of the main plant within the secondary
containment of the main plant. Like the tanks in the main plant, all of the leaks, drips and spills are
collected in the trench drains and processed within the wastewater pretreatment system. Piping
locations for loading and unloading operations in this area are labeled to indicate their respective
discharge locations.
The surface of the tank truck loading/unloading area is concrete. This surface is periodically washed
to minimize the tracking of chemicals outside of the containment structure by tank wagons or forklift
tires.
D.3. Monitoring of Transfer Operations and Equipment
All transfer operations are monitored by personnel throughout the transfer. Further, plant personnel
inspect any hoses, connection fittings, piping and pumps prior to starting the transfer and during the
transfer.
E. SECURITY
Security is controlled by plant personnel being on -site 24 hours a day when the plant is operating.
When the plant is not operating, security personnel are on -site. Security personnel make rounds on a
continuous basis to ensure frequent visits to all tank storage areas. Part of the security personnel's
responsibilities includes at least bihourly visits to each of the monitoring panels. Monitoring panels
are located at each tank farm area and at multiple locations within the main plant.
Lighting is sufficient throughout the facility to allow detection of a spill at night.

F. SPILL PREVENTION AND MITIGATION PROCEDURES
F.I. Spills Outside of Containment Structures
Employees are required to immediately clean up any spill or leaks outside of containment structures. Any
spill that occurs outside of a containment structure that cannot be controlled is immediately reported to
emergency agencies by dialing 911. Further, Chemol will contract the services of Shamrock
Environmental or other approved company to provide emergency remediation and response.
F.2. Spills Inside of Containment Structures
Spill of material inside of containment structures are either recovered for reuse or placed into the plant's
process sewer system. The actions taken are appropriate for the amount of material spilled and its hazard
level.
F.3. Training
All employees who work in the processing area are trained in the operation of equipment to prevent
discharges of process chemical into storm water. This training is held in conjunction with Spill
Prevention, Control and Countermeasure (SPCC) Training and includes a discussion of material transfer
and acceptance procedures, and applicable laws, rules and regulations. A knowledgeable person provides
this training with experience in spill response, containment and control. Training is conducted at least
once per year for these personnel.
During the training session, a briefing is held to assure adequate understanding of the SPCC Plan and
Stormwater Pollution Prevention (SPP) Plan. These briefings also highlight recent spill events, failures,
and precautionary measures. Records of employee training sessions are maintained with the SPCC Plan
and are kept for at least three years.
Additional annual training on uncontrolled spills occurs as part of the Emergency Action Plan Training
Program. Records of this training are maintained.
G. Waste Streams and Handling
G.1. Plant Process Sewer Liquid Waste
All rainwater and residual chemicals collected in any of the tank farms or production areas enter the
plant's sewer system. The materials are acidified to separate any oil layer from the water layer. The water
layer is separated, neutralized and discharged to the City of Greensboro's Sanitary Sewer System. The
grease layer is sold as a non -hazardous by-product stream.

Updated: February 2022
DCX.Uilv1EN.1_._F.i..�_LLE; DUiUtlli�ill y�lbl:C�'�

G.2. Solid Waste from Production, Warehouse, Maintenance, Laboratory and Office
Operations
Chemol's operations generate non -hazardous solid wastes that are sent to a licensed landfill. The
solid wastes are placed in one of two "rolloff containers. One of these containers is within the plant's
containment structure. Any runoff of rainwater from this container would go into the main plant's
containment structure.
The second solid waste dumpster is placed over a collection sump which collects any rainwater
runoff. Any runoff is then pumped into the main plant's process sewer.
G.3. Laboratory Hazardous 'Waste
Chemol's laboratory operations generate small quantities of hazardous waste.
This waste is removed by licensed hazardous waste haulers and for documented disposal. Records of
waste generated and its associated disposal are maintained.
H. Preventive Maintenance
Chemol has a preventive maintenance program involving scheduled maintenance on all equipment.
This program is currently being updated to enhance its effectiveness and formal documentation.
Further, Chemol has a work order system to repair any unplanned equipment failures. Any
maintenance activity required to address potential or actual stormwater contamination is considered a
high priority relative to other maintenance activities.
I. Pallet Storage
Chemol stores a variety of wooden pallets in uncontained areas. The large majority of these pallets
are new and do not pose a potential to contaminate stormwater. A small number of pallets (averaging
below 50) have been used in the production area and could be contaminated with small quantities of
non -hazardous materials. Runoff from these pallets could potentially contaminate stormwater.
Currently, all used pallets are removed from the site by a pallet recycler. Chemol currently purchases
heat treated pallets which are clean or new.
