Dear Mr. Dagenhart:
DONALD R. VAN DER VAART
Secretary
TRACY DAVIS
Director
On June 23, 2016 Glen White:of the North Carolina Department of Environmental Quality,
Department of Energy, Minerals, and Land Resources met with you and Shawn Rudison,
Chemical Regulatory Specialist, at the facility located at 2001 Willow Springs Lane, Burlington,
to conduct a compliance inspection per the Industrial Stormwater Permit requirements. This
inspection consists of review of the Stormwater Pollution Prevention Plan, training, monitoring
and spills records as well as observation of the general condition of the site, the outfalls and any
possible exposures to downstream stormwater. Your assistance with the inspection was greatly
appreciated.
Permit:
This facility holds General Stormwater Permit NCG060040 to discharge stormwater from
industrial activity associated with Food and Kindred Products [SIC 20] under the National
Pollutant Discharge Elimination System (NPDES). The permit became effective December 01,
2012 and expires on October 31, 2017. A copy of the current permit is required to be maintained
with the Stormwater Pollution Prevention Plan (SPPP) documents. The current permit was
available for review and was included in the SPPP.
Record"evorts:
This facility was required to develop and maintain a Stormwater Pollution Prevention Plan
(SPPP) in accordance with Part II, Section A of the permit. The SPPP has been updated annually
as required and contained all components as required. Mr. Rudison conducts the required
monitoring and samples are sent to Meritech or Reidsville for analysis. All recent results fell
within parameters with the exception of TSS (Total Suspended Solids) at Outfall 3. Mr. Rudison
believes the exceedance was due to elevated pollen in the area when sampling was completed.
No deficiencies noted.

Facility Site Review:
This facility manufactures textile chemicals used to change material properties of textile
products. It has (9) nine blend vessels and (4) four reactors in the production process. The tank
farm has secondary concrete containment. Flammable materials and chemicals are stored
outside near the back door. Pallets and empty drums are stacked neatly and stored outside.
Effluent Receiving Waters:
Effluent from this facility drains to Gum Creek (Class C; NSW) in the Cape Fear River Basin.
Self -Monitoring Program:
The plant has (4) four outfalls all located along the wood line near the edge of parking. Outfalls
2 and 4 have spill control valves that can be activated if a spill occurs. These are the outfalls
with the most potential to be in the path of a spill from either the plant or loading/unloading
areas. No deficiencies noted.
The facility was found to be compliant with requirements of its industrial stormwater permit. If
you have questions or need additional information, please contact Glen White at [phone].

Comment: Analytical monitoring as required twice annually. Last sampling showed elevated TSS at outfall
3. No other paramete.rs exceeded. Samples were taken in late April when pollen levels were
very high and likely the source. No deficiencies noted.

Comment: Facility has 4 outfalls. Outfalls 2 and 4 have gates that can be closed if there is a spill at the
facility. All outfalls observed and easily reached for sampling. Minor oily sheen and bubbles
were seen at Outfall 3. Inspector does not believe this somes from any of the facilities industrial
activity. Possibly due to natural processes in that wooded area.

Subject: RE: Report on Process -Water Spill into Stormwater System
The sump pit (7ft deep X 10 ft. X 11 ft.) has now been cleaned completely by an outside contractor and the flow of water
appears normal. We have decided to abandon the idea of a sump pit level indicator due to our belief that sludge may
lead to incorrect readings. The action plan now involves visual examination of the sump pit once a week with removal of
sludge by directed water flow using a hose each week if needed. This action plan will allow monitoring of the sludge
build up so we can respond with an outside contractor before the drain becomes completely closed.

Ms. Jenny Graznak
NC DENR, Division of Water Quality
(via email to [e-mail])
Dear Ms. Graznak:
On Tuesday, July 16, at about 2 pm, an overflow of process -wash water from the POTW-discharge system of Apollo
Chemical — Burlington Facility onto the ground in the parking lot near the shipping dock and dumpster area of the plant
site was discovered by a Shipping Supervisor. Site Management was informed, and action was taken to stop the
overflow and remediate the problem. The overflow was entering the stormwater-drain grating in the parking lot near
the dumpster area, and consequently outflowing from SDO-2. The drain gratings in the immediate area were blocked to
prevent additional water from entering the stormwater system, and the spill was pumped into tote tanks. It was
estimated that 600 Gallons of process -wash water entered the stormwater-drain system. Samples collected from the
SDO-2 outfall and ditch were tested for pH, solids and specific gravity. pH was 7.7, solids were 0% by microwave
analysis, and specific gravity was 0.996. Those parameters indicate no significant chemical contamination of the
discharged water. The only indications of any contamination were an off-white translucent appearance and slight
foaming of water in the discharge ditch. No visual effect could be observed in Gum Creek downstream of the
stormwater-drainage ditch.
Upon investigation, it was found that a partial blockage of the POTW-discharge line apparently caused a backup into the
containment pit and then the subsequent overflow. A surge of process wastewater had been released just prior to the
backup and overflow. The overflow ceased when the surge of the discharge had been completed. The site's
maintenance supervisor and a contract plumber cleared the sewer -discharge line, and the POTW flow resumed
normally.
The Apollo Chemical — Burlington Facility Certificate of Coverage Number is NCG060040, Documentation of the
circumstances of this discharge will be filed with our Stormwater Pollution Prevention Plan. If additional information or
reporting is needed, please contact me.
Best Regards,

Subject: Compliance Evaluation Inspection
NPDES General Stormwater Permit No. NCG060040
Mount Vernon Chemicals, LLC — Apollo Chemical
Alamance County
Dear Mr. Dagenhart:
On April 16, 2013, Jenny Graznak of this office performed a Compliance Evaluation
Inspection at Mount Vernon Chemicals in Alamance County, North Carolina. This facility holds
General Stormwater Permit No. NCG060040 under the National Pollutant Discharge Elimination
System (NPDES) to discharge Stormwater from Food and Kindred Products, etc. You were present
for the inspection. This type of inspection consists of two basic parts: a review of facility files and
self -monitoring data, and an on -site inspection of the facility's outfalls. This particular inspection
evaluated five (5) areas as designated on the EPA inspection form, and observations from each area
are addressed below:
1. Permit
The permit became effective December 1, 2012 and will expire October 31, 2017. A copy of the
permit was available on site for review.
2. Records/Reports
As required by the Permit, the facility has a Stormwater Pollution Prevention Plan (SPPP) that was
last updated in December 2012. The SPPP appeared to be thorough and complete, including a
location map of the outfalls, and a site plan listing potential stormwater pollutants and best
management practices used at the site. Employee Training occurs on an annual basis and was
documented in the SPPP. The last employee training event occurred on March 27, 2013.
3. Facility Site Review
Mount Vernon Chemicals manufactures textile chemicals. This facility has bulk storage of flammable
materials and chemicals at the back dock. The Burlington Fire Department requires these materials
to be maintained outside. The concrete floor of the bulk storage area is sloped, leading to a floor
drain that is plumbed to discharge to the local POTW. In addition to the bulk storage area, there are
used pallets stored outside under a tarp. The site also has a covered garbage dumpster and an
uncovered dumpster for recyclables. There are also loading and unloading areas at the site.
4. Effluent/Receiving Waters
Stormwater discharges from this site drain to Gum Creek (Class C, NSW) in the Cape Fear River
Basin via four outfalls. Two of the four outfalls have a spill control valve that can be manually
activated. No concerns were noted with respect to the visual appearance of the outfalls.

5. Self-Monitorina Program
The stormwater permit requires semi-annual analytical and qualitative monitoring of each outfall. An
on -site review of the monitoring data during the inspection showed that all parameters were
evaluated per the specifications of the permit. Meritech performs the analysis for all samples, except
pH, which is analyzed on site. A rain gauge is maintained on site to collect rain data. This
information is also verified by the rain data from the local Burlington Airport. On -site vehicle
maintenance monitoring requirements at the site are waived, since these activities are not performed
on site.
You are found to be in compliance with General Permit No. NCG060040. Please refer to the
attached report for further details from the inspection. If you have any questions concerning this
report, please contact Ms. Graznak or me at [phone].

Some of the changes include:
Part Il:
• Section A: The Stormwater Pollution Prevention Plan (SPPP) section, if applicable, has been updated
to the most current language of our permits. Additional conditions for specific industry sectors have
been added to the SPPP requirements in some cases.
• Sections B, C: Failure to perform analytical stormwater monitoring may result in the Division requiring
that the permittee begin a monthly sampling scheme.
• Sections B, C: A lower TSS benchmark of 50 mg/I for HOW, ORW, PNA and Tr Waters applies to these
more sensitive waters.
• Sections B, C: The monitoring parameter Oil & Grease (O&G) has been replaced by the parameter
Total Petroleum Hydrocarbons (TPH) for vehicle maintenance areas, and in some cases, other
analytical monitoring requirements.
• Sections B, C, D: Inability to sample due to adverse weather must be recorded in the SPPP, or in
separate on -site records if your General Permit does not require an SPPP. Adverse weather is defined
in the "Definitions" section of the permit.
• Sections B, C: The term "Representative Storm Event" has been replaced by "Measurable Storm
Event." A measurable storm event is defined in the permit.
• Section D: If the permittee fails to respond effectively to problems identified by qualitative
monitoring, DWQ may require the permittee to perform corrective action.
Please review Parts III and IV to understand the Standard Conditions of your new NPDES General Permit,
including Compliance and Liability, Reporting, Monitoring and Records requirements; Operation and
Maintenance obligations; and Definitions. Please note that all samples analyzed in accordance with the terms
of this permit must be submitted to the Division on Discharge Monitoring Report (DMR) forms available on
the Stormwater Permitting Unit's website above. DMR forms must be delivered to the Division no later than
30 days from the date the facility receives the sampling results from the laboratory. Also note that existing
permittees do not need to submit a renewal request prior to expiration unless directed by the Division.
Your coverage under the General Permit is transferable only through the specific action of DWQ. This permit
does not affect the legal requirements to obtain other permits which may be required by DENR, nor does it
relieve the permittee from responsibility for compliance with any other applicable federal, state, or local law,
rule, standard, ordinance, order, judgment, or decree. If you have any questions regarding this permit
package, please contact the Division's Stormwater Permitting Unit at [phone].

Your request to continue sampling stormwater discharges from outfall #2 for the above referenced
facility for purposes of NPDES stormwater permit monitoring requirements has been reviewed by
Steve Ulmer of our Water Quality staff. Based on your letter of February 9, 1996, we agree that outfall #4
would seem to discharge stormwater primarily from the automobile parking area which is not considered
industrial activity under the stormwater federal regulations.

Dear Mr. Alexander:
Your request to sample one stormwater discharge outfall identified on your map as Outfall #2 at the
subject facility for purposes of NPDES stormwater general permit monitoring requirements has been
reviewed by members of the Water Quality Section staff. Your request described three (3) outfalls at the
facility, one of which discharges stormwater from industrial activities.
Based upon staff review of your letter dated November 9, 1993, with attached site map and
accompanying analysis data, we have concluded that the requested determination is warranted and in
accordance with Part 1, section B4 of the general permit, as stormwater discharges representative of the
runoff from the Burlington Chemical Company, Inc., facility for the gencral permit.
If you have any questions concerning this authorization, please contact Mr. Stephen Ulmer at (919)

Re: Petition for Representative Outfall Determination
and Submittal of Stormwater Monitoring Report
Burlington Chemical Company, Inc.
Certificate No. NCG060040
Dear Mr. Ulmer:
On behalf of our client Burlington Chemical Company, Incorporated, we are submitting the attached
Stormwater Discharge Outfall Monitoring Report. Although there are three outfalls at Burlington
Chemical's Willow Springs Lane Facility only Outfall #2 was sampled. Therefore, at this time we also
request that this outfall be declared their representative outfall for stormwater monitoring.
In order to illustrate that Outfall #2 is representative, we have attached a site plan of the facility for your 1_�
review. The site plan shows the three outfalls and their relationship to the plant. Based on our inspection
of the facility, we determined that all of the outdoor industrial activity occurs at the two loading areas. 15
Chemicals are also stored on the loading area at the west end of the building. This chemical storage area
covered for the most part and diked.
Generally, all the plant area drains towards Gunn Creek. Therefore, any precipitation in the work areas-.
. Fri ...-
drains toward the three catch basins that feed to Outfall #2. The other two outfalls would primarily receive...
7-
runoff from the haul roads and the automobile parking area. Therefore Outfall #2 is the one most likely to-
(= Cl
receive stormwater related to industrial activity. In addition, the entire parking/loading area has ao—o
_=
containment berm that prevents plant area runoff other than through the three outfalls.
-'
Please let us know in writing if the state will allow Outfall #2 to be considered the sole stormwater
sampling point for the Burlington Chemical facility. If you have any questions about the facility or this
request, please feel free to contact us.
