Section 1. Facility Activities and Process:
Chemcol Company, Inc. uses renewable animal fats,vegetable oils, and fatty acid derivatives as the base
raw materials for the production of various chemicals, lubricants, coatings, etc. These are processed by
refining and bleaching, hydrogenation,blending esterfication and poly-condensation reactions. Various
alcohols are used in esterification. All water from secondary containment is processed by grease trap and
discharged to the POTW. No. 2 fuel oil can be stored within the main plant for water and hot oil boiler
fuel. Non-oil products (alcohol, water and water-based solutions) are also stored at the facility.
Per the 2016 DEMLR inspection report,the facility renders animal fats for the manufacture of esters and
amides of fatty acids. Transesterifications (mixing chemicals to react and form another compound) of esters.
The facility refines,bleaches, and hydrogenates fats and oils (triglycerides) and distillation of esters. It has
blending,packaging, and warehouse operations. Packaging includes flaking,prilling, drumming and loading
bulk containers. There is a laboratory that supports manufacturing.
Per the 2022 permit renewal application, no significant process changes have occurred,but the volume is
increasing and equipment as tanks and reactors are being replaced and added. All operations are within
secondary containment or monitored at the railroad.
Per information provided by the permittee via email on 7/27/2023 and 7/28/2023, the flow to the north
of outfalls 1 and 2 is sheet flow and area goes across the adjacent parking lot into a 150 feet permeable
buffer zone. The flow is visually monitored and contains only packaging materials that are clean and
empty. The plant is fully diked and all process water is treated and sent to Greensboro waste water
system.
Outfall SWO01:
Drainage area consists of plant operations,pallet storage (some could be contaminated from production
area), loading/unloading dock, and bulk shipping.
Page 1 of 6

Outfall SW002:
Drainage area consists of rail car loading/unloading, tank farm, parking lot, waste dumpster, and storage
areas.
Why Industrial Sites with Stormwater are Subject to a Permit: Federal NPDES regulations define
stormwater discharge associated with industrial activity in 40 CFR §122.26 (b)(14) as: "the discharge
from any conveyance that is used for collecting and conveying storm water and that is directly related to
manufacturing,processing or raw materials storage areas at an industrial plant. The term does not
include discharges from facilities or activities excluded from the NPDES program under this part 122.
For the categories of industries identified in this section, the term includes, but is not limited to, storm
water [sic] discharges from industrial plant yards; immediate access roads and rail lines used or traveled
by carriers of raw materials, manufactured products, waste material, or byproducts used or created by
the facility; material handling sites; refuse sites; sites used for the application or disposal of process
waste waters (as defined at part 401 of this chapter); sites used for the storage and maintenance of
material handling equipment; sites used for residual treatment, storage, or disposal; shipping and
receiving areas; manufacturing buildings; storage areas (including tank farms) for raw materials, and
intermediate and final products; and areas where industrial activity has taken place in the past and
significant materials remain and are exposed to storm water. For the purposes of this paragraph, material
handling activities include storage, loading and unloading, transportation, or conveyance of any raw
material, intermediate product, final product, byproduct or waste product. The term excludes areas
located on plant lands separate from the plant's industrial activities, such as office buildings and
accompanying parking lots as long as the drainage from the excluded areas is not mixed with storm
water [sic] drained from the above described areas."
Section 2. Monitoring Information and Compliance History:
• March 2017 to June 2023, benchmarks exceeded for:
o SW001: Total phosphorus Ix, BOD 5x, COD 4x, TSS 3x,pH min not reached 5x
o SW002: Total phosphorus 2x, BOD Ix, TSS 3x,
• ROS at SW001 removed in 2016 inspection report
• Per the December 2017 City of Greensboro Stormwater Management Division inspection report:
o Product has been tracked out of the secondary containment near the railcar
loading/unloading
o An area of soil disturbance (with recently added straw) adjacent to the secondary
containment wall not noted in the facility's SWPPP
• Per the October 2021 City of Greensboro Stormwater Management Division inspection report:
o A leaking, decommissioned grease container was noted near the railroad spur.
o Grease noted on one of the berms located near the main plant. The grease was likely
deposited by continuous use of this berm section as ingress/egress to the diked area.
Should a rain event occur, the material located on the outer edge of the berm would flow
into the stormwater system.
• On 12/31/2017 a valve on one of the ASTs froze and busted. About 100 gallons of oil/grease
product made outside of the secondary containment Some product made it to the curb line of the
street,but it was cold enough to freeze and stop it from flowing any further.
• Per the July 2023 inspection report, Tier response not conducted for TSS, COS, and nitrogen
benchmark exceedances and water is bypassing trench drains that feed the wastewater treatment
Page 2 of 6

plant. Two outfalls were noted in the SPPP,but a potential third was observed during the
inspection that does not drain to the other outfalls. This outfall needs to be monitored as well.
o William Newlin (Chemol Company; via email 8/16/2023): The mentioned outfall three
area (as I understand the area to be), does not meet the definition of an outfall. I stated
this during the inspection. The flow to the north of outfalls 1 and 2 is a sheet flow area
that goes across the adjacent Darling International gravel parking lot into a 125+feet
wide buffer zone. There is no centralized collection point (Catchment Area) for sampling,
so outfall coordinates cannot be supplied. This area serves as a driveway/parking area and
is visually monitored. Concerning the water that was bypassing the trench drains: At
Outfall#1, Chemol is going to install a berm across the parking lot/driveway to divert
this water into a collection sump that goes to Chemol's wastewater system for processing.
o DEMLR response: Per phone call with Lily Kay (8/18/2023), a trench drain that collects
stormwater leads to a pipe that goes to large grassy area then then the road. Lily says they
need to make sure the stormwater does not leave the property (that it infiltrates)but if it
does then they need to sample it. Central Office has decided a permit condition will be
added to the permit requiring they monitor the drainage area during four(4) storm events
and require permit modification if discharge is observed to leave the property.
Threatened/Endangered Species:
There are no threatened/endangered species in the nearby vicinity of the facility, however there is one
(1) species of concern: Lowland Loosestrife (Steironema hybridum;NC status: SR-P).
Section 3. Proposed Monitoring for Stormwater Discharges:
The Division considered potential pollutants from past and present industrial activities and data was
submitted for March 2017 to June 2023. Quantitative sampling included pH, TSS, O&G, total nitrogen,
total phosphorus, COD, and BOD.
Parameters are based on potential pollutants in the drainage area, sampling results, and in some cases,
dependent upon future activities (e.g., ash removal through the drainage area). Below is a table of the
proposed monitoring for each outfall at the Chemcol Company, Inc. site.

Stormwater Benchmarks and Tiered Response: Rather than limits,North Carolina NPDES
Stormwater permits contain benchmark concentrations. Stormwater benchmarks are numerical action
levels for stormwater monitoring. Benchmarks are not effluent limits, and benchmark exceedances are
not permit violations. Benchmarks provide facilities a tool for assessing the significance of pollutants in
stormwater discharges and the effectiveness of best management practices (BMPs). Benchmark
concentrations are intended as guidelines for the facility's development and implementation of the
Stormwater Pollution Prevention Plan (SWPPP).
Benchmark exceedances require the permittee to increase monitoring, increase management actions,
increase record keeping, and/or install stormwater BMPs in a tiered program. The permit establishes a
tiered approach to specify actions the permittee must take in response to analytical results above
benchmark concentrations. The tiered structure of the permit provides the permittee and DEMLR wide
flexibility to address issues that may arise with one or more parameters and/or outfalls.
Metals benchmarks are calculated to mimic acute water quality standards and with the guidance of
DWR. NC DWR follows established federal procedures for calculating acute standards when developing
the benchmarks. Just like the acute standards, metals benchmarks normally reflect one half of the
calculated Final Acute Value (the "1/2 FAV"). In most cases, translation into total recoverable values is
based on an assumed hardness of 25 mg/L and a total suspended solids (TSS) concentration of 10 mg/L.
Acute standards protect aquatic life from negative impacts of short-term exposure to higher levels of
chemicals where the discharge enters a waterbody. The Stormwater Permitting Program applies this
approach because of the ephemeral nature of rainfall events.
The Division may evaluate results to determine if a smaller suite of parameters for some outfalls is
adequate to characterize potential pollution or BMP effectiveness. For example, one or more metals or
other parameters may serve as an adequate tracer for the presence of ash pollution during disturbance or
ash removal in specific drainage areas at this site. For parameters that do not have a stormwater
benchmark, the Division may develop a benchmark value if appropriate toxicity data become available
or if rising trends in concentrations suggest a persistent source.
A summary of the benchmarks in the draft permit, and their basis, is below:
Page 4 of 6

Parameter Benchmark Basis
Total Suspended 100 mg/L National Urban Runoff Program(NURP) Study, 1983
Solids TSS
H 6 s.u. —9 s.u. NC Water Quality Standard(Range)
Non-Polar Oil & Review of other state's daily maximum benchmark
Grease 15 mg/L concentration for this more targeted O&G;NC WQS that
EPA Method 1664 does not allow oil sheen in waters
SGT-HEM
BOD 30 mg/L BPJ; Based on Secondary Treatment Regulation(40 CFR
133.03
COD 120 mg/L BPJ; Generally found at levels 4x BOD5 in domestic
wastewaters
Total Nitrogen 30 mg/L TKN+Nitrate+Nitrite Benchmarks (Expressed in mg/L of
N
Total Phosphorus 2 m /L BPJ; Based on wastewater permit limits for NSW waters
Stormwater Pollution Prevention Plan: The proposed permit conditions reflect the EPA and NC's
pollution prevention approach to stormwater permitting. The Division's maintains that implementation
of Best Management Practices (BMPs) and traditional stormwater management practices that control the
source of pollutants meets the definition of Best Available Technology (BAT) and Best Conventional
Pollutant Control Technology(BCT). The permit conditions are not numeric effluent limitations but are
designed to be flexible requirements for implementing site-specific plans to minimize and control
pollutants in stormwater discharges associated with the industrial activity. Title 40 Code of Federal
Regulations (CFR) §122.44(k)(2) authorizes the use of BMPs in lieu of numeric effluent limitations in
NPDES permits when the agency finds numeric effluent limitations to be infeasible. The agency may
also impose BMP requirements which are "reasonably necessary" to carry out the purposes of the Act
under the authority of 40 CFR 122.44(k)(3). The conditions proposed in this draft permit are included
under the authority of both of these regulatory provisions. In essence, the pollution prevention and BMP
requirements operate as limitations on effluent discharges that reflect the application of BATBCT.
Flexibility in Tier Responses: Tier Two actions provide an opportunity for the permittee to propose an
alternative monitoring plan for approval by the Region:
• Alternatively, in lieu of steps 2 and 3, the permittee may, after two consecutive exceedances,
exercise the option of contacting the DEMLR Regional Engineer as provided below in Tier
Three. The Regional Engineer may direct the response actions on the part of the permittee as
provided in Tier Three, including reduced or additional sampling parameters or frequency.
• If pursuing the alternative above after two consecutive exceedances, the permittee may propose
an alternative monitoring plan for approval by the Regional Engineer.
The permit therefore allows the permittee to petition the Regional Office for monitoring changes sooner
than Tier Three (upon any four benchmark exceedances) and gives guidance on one option to take. For
example, the permittee may request that mercury only be monitored semi-annually under the tiers, or
that only parameters over the benchmark be monitored more frequently. In this way, changes to the
monitoring scheme for any outfall could be handled outside of a permit modification.
Other Proposed Requirements:
• It is standard for Stormwater Pollution Prevention Plan(SWPPP) requirements to include an
annual certification that stormwater outfalls have been evaluated for the presence of non-
Page 5 of 6

stormwater discharges, and if any are identified, how those discharges are permitted or otherwise
authorized.
• Requirement to submit a request for permit modification if the facility identifies or creates any
new outfalls, removes outfalls, or alters any drainage area that changes potential pollutants.
• The Division expects the permittee to apply best professional judgment and consider the safety
of its personnel in fulfilling sampling obligations under the permit.
• Federal regulations require electronic submittal of all discharge monitoring reports (DMRs). If a
state does not establish a system to receive such submittals, then permittees must submit DMRs
electronically to the EPA.
• Quarterly QualitativeNisual Monitoring to assure regular observation of outfalls throughout
year.
Section 4. Changes from previous permit to draft:
• Monitoring increased from semi-annually to quarterly for all parameters (qualitative and
quantitative)
• "No discharge" clarifications made
• Feasibility study requirement removed per updated stormwater program requirements
• eDMR requirement added
• Boilerplate language moved into body of the permit; boilerplate no longer attached
• Outfall-specific monitoring been implemented to reflect industrial activity and potential
pollutants specific to each discharge area
• Permit condition added in Part D to evaluate potential third outfall location (per July 2023
DEMLR inspection report)
• Benchmarks updated for parameters per guidance from DWR Standards group on stormwater
benchmarks
Section 5. Changes from draft to final:
• None

• Initial contact with facility: 7/18/2023
• Initial contact with Regional Office: 7/18/2023
• Draft sent to CO peer review: N/A
• Draft sent to Regional Office: 8/23/2023

Brianna,
The mentioned outfall three area (as I understand the area to be), does not meet the definition of an outfall. I stated this
during the inspection. The flow to the north of outfalls 1 and 2 is a sheet flow area that goes across the adjacent Darling
International gravel parking lot into a @125+feet wide buffer zone. There is no centralized collection point(Catchment
Area)for sampling, so outfall coordinates cannot be supplied.This area serves as a driveway/parking area and is visually
monitored.
Concerning the water that was bypassing the trench drains.
At Outfall#1, Chemol is going to install a berm across the parking lot/driveway to divert this water into a collection sump
that goes to Chemol's wastewater system for processing.

An outfall is a point where the MS4 discharges from a pipe or other conveyance
(e.g. a ditch) directly into surface waters.

Brianna,
Please find the copy of documents that you requested in your email dated 7/18/23 concerning needed documents for
renewal of storm water permit NCS000048 for Chemol Company Inc. There have been no operational changes since the
renewal application was submitted and the information on the renewal application is still complete and correct.
Chemol uses oils in the form of animal fats,vegetable oils, and fatty acid derivatives.No. 2 fuel oil can be stored within
the main plant for water and hot oil boiler fuel.Non-oil products (alcohol,water and waterbased solutions) are also stored
at the facility.
Chemol maintains secondary containment around all of its oil and chemical storage areas and has determined the use of
training,documented procedures for inspection of equipment, and maintaining readily available equipment to prevent
discharge of oil from reaching navigable waters is practical and effective for this facility.
Please confirm if we need to send a hard copy to you.

Good morning,
I am working on renewing the individual stormwater permit for the Chemol Company, Inc. (NCS000048). I
need additional information in order to 1) confirm that the information I have is correct and 2)make sure the
permit adequately serves the needs of the facility. Please provide the following:
• EPA Form 2F is missing the following items:
o Section 4.2: The significant material section is blank.
o Section 5.1: Signature for certification of non-stormwater discharges is missing.
• Description of industrial activity occurring and chemicals stored onsite;
• Description of industrial activity in each drainage area;
• An electronic spreadsheet summarizing all of the monitoring data that has been collected since the
effective date of the current permit; Does this mean a list of all sample analysis since 2017?
• Verification that the information in the renewal application is still complete and correct; and
• An explanation of any operational changes since the renewal application was submitted.
Enter your stormwater permit number into the Stormwater Permit Summary Report and you will see a form that
includes the address of the facility,contact information for the permit, and the regulated stormwater outfall(s)for the
facility. Please review the facility information to make sure it is correct. Information can be updated using the links
provided below,where applicable:
• Facility/Company name or ownership: Name/Ownership Change Form
• Owner Affiliation (Legally responsible person; i.e., someone with the company who is designated to
represent the company per signatory requirements or another authorized representative): Permit Contact

• Delegation of Signature Authority (DOSA): Permit Contact Update Request Form
• Billing contact: Permit Contact Update Request Form
• Permit contact: Permit Contact Update Request Form

• Facility address only: Email Bethany og ulias
• Stormwater outfall information: Email Bethany Georgoulias
• Visit the eDMR Six Steps website and complete Steps 1 and 2.
• Pay outstanding permit fees: Stormwater ePgMent website
Once I have the above listed information, I can continue my review. You will receive a draft permit for a 30-day
comment period. During this time we will be able to address any comments or concerns you have. During the
same 30-day period, the draft will be sent to a Regional Office staff member for review as well as out to public
notice. Once all comments and concerns are addressed, you may be issued a final permit.
Please contact me if you have any questions.

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 5-28,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 5-28(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.

A.3. Ester Tank Farm
All 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.6. 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 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 21/16

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 strictures 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-
1 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
[DOCUMENT TITLE 11 [Documer,t suhiitle]

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
plants 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.

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.
