industry, AlphaGary is undeniably a leader in its markets and continues to develop
and deliver custom-made, value -adding solutions in partpership with its customers.
This will continue under the new name of Mexichem Specialty Compounds.

Compounds - all other details, including the addresses for the company and our
Federal ID number will remain the same. Before this date invoices addressed to

name change.

ADDENDUM
The National Pollutant Discharge Elimination System (NPDES) program was established under the federal
Clean WaterAct and then delegated to the Division of Water Quality for implementation in North Carolina. The
NPDES permitting program for stormwater discharges was established in 1990. Phase I focuses on site and
operations planning to reduce pollutant sources.
Through the NPDES permitting program industrial facilities that fall into one of the subject ten categories are
required to obtain permit coverage under a general permit or an individual permit, depending upon the
facilities SIC code and the industrial activity occurring at the facility. There are currently 19 active general
stormwater permits in North Carolina. One condition that is applicable to both the general permits and
individual stormwater permits is the requirement to develop and implement site -specific comprehensive
stormwater pollution prevention plans (SPPP). These plans are required to include a comprehensive
evaluation of the site and operations to reduce pollutant sources and prevent pollutant discharge in stormwater
runoff.
Copies of the general permits and accompanying documents can be accessed from the following webpage:
http://portal.ncdenr.org/web/wg/ws/su/npdessw#General Permits NPDES Permit text, technical bulletins,
discharge monitoring forms, a Notice of Intent [which is the application of for coverage under a NPDES.
General Stormwater Permit), and the Representative Outfall Status application can be found on this website.
The following items are a subset of permit requirements and are listed to assist you and help bring your
attention to certain permitting issues, process, and condition requirements of your permit. Please see the
abovementioned website to obtain a copy of the permit so you may fully comply with the conditions therein.
Failure to properly comply with conditions of the permit, fike those bulleted below, constitutes permit
violations and is subject to civil penalty assessment of up to $25,000.00 per day.
• Industrial facilities that fall into one of the subject ten categories are required to obtain permit coverage
under a general NPDES stormwater permit or an individual NPDES stormwater permit
• All persons desiring to have facilities covered by a General Permit must register with the Division of
Water Quality (DWQ) by the fling of a Notice of Intent (NOI) and Applicable Fees.
• This Notice of Intent (NOI) must be submitted.and a Certificate of Coverage issued prior to any
discharge of stormwater associated with the industrial activity, process wastewater, and/or mine
dewatering.
• Once the Notice of Intent is received, DWQ will review and determine whether a Certificate of Coverage
(COC) may be issued. If this Certificate of Coverage is issued the facility is covered by the General
Permit. That is, the permittee is authorized to discharge stormwater, process wastewater, and/or mine-
dewatering (pursuant to the type of General Permit) until the permit expires or is modified or revoked.
• Any other point -source discharge to surface waters of the state is prohibited unless it is an allowable
non-stormwater discharge or is covered by another permit, authorization, or approval.
• There are currently 19 active general permits. Permit conditions vary accordingly; however, most of the
permits have the following condition requirements (you must read your entire permit to ensure full
compliance):
o Development and compliance with the Stormwater Pollution Prevention Plan
o Collection, reporting, and recording of Analytical Monitoring
o Collection, reporting, and recording of Qualitative Monitoring

Comment: The permittee had a well -developed and implemented Stormwater
Pollution Prevention Plan (SPPP). However, the SPPP did not contain documentation
that inspections of the stormwater facilities had been completed. Please start
documenting these inspections required by Part II, paragraph 8 of the general permit.
The Spill Response Team is trained in the stormwater permit and impacts to stormwater
runoff as well as all new employees. Training covers employees on all shifts at the
facility since production is conducted 24/7.
There have been no spills in the last three years. A spill of diesel fuel from a third -party
transporter was reported to DWQ through Incident 200802905.

Permit and Outfalls
# Is a copy of the Permit and the Certificate of Coverage available at the site?
# Were all ou falls observed during the inspection?
# If the facility has representative outfall status, is it properly documented by the Division?
# Has the facility evaluated ail illicit (non stormwater) discharges?
Comment: Permittee had noted 4 outfalls in the Stormwater Pollution Prevention
Plan. However, during the site inspection it was determined that an additional outfall
should be designated (outfall 005).
There was a large amount of accumulated sediment in the drop inlet liners for catch
basins that drain to outfall 004. There was also an oily sheen on the water accumulated
in the corner of this area that should be absorbed and disposed of properly_ Some of
the outfall structures/pipes have begun to be impacted by accumulated sediment/resin.
The permittee should perform the required maintenance to ensure these structures
perform as designed as required by Part III, Section C, paragraph #1.

Dear Ms. Allocco:
RECEIVED
M-Surface Water PratecHon
1 am writing this letter to follow up on my telephone call to you last Friday, October 10', in which I
reported a diesel fuel spill from a Fed -Ex delivery truck that discharged onto our property and into a storm
drain. The Fed -Ex truck was bringing a delivery to our facility and the driver arrived late in the evening on
Thursday, October 4'h, parking outside one of our locked gates on a public right-of-way. Sometime during
the night, as evidenced by the attached photos taken by our security cameras, a leak occurred from the
truck's fuel tank, flowing onto our driveway and into the storm drain. By about 7 a.m., the truck had been
driven to the other end of our property where the delivery was made. The driver did not mention the spill
to us. Because our plant operations were shut down on Friday and there was a reduced staff on -site, the
spill was not discovered until approximately mid -day Friday. The spill entered a storm drain that feeds into
a settling pond on our property, which happened to be dry at the time of the incident. A copy of a portion
of our stormwater pollution prevention plan (SWPPP) site plan is included with this letter to diagram the
spill. Our SWPPP was developed in accordance with the requirements of our stormwater permit,
(, CGO50 52 -it will be updated to include a narrative for this spill. The spill was cleaned up by a
hazardous material cleanup crew on Friday afternoon. In addition to cleaning the driveway, the crew
released approximately 150 gallons of water into the storm drain and suctioned the discharge at the point
where it drained into the settling pond. Several absorbent booms were also placed at the discharge point to
capture any potential residual fuel. We have inspected the settling pond several times since the cleanup and
there is no evidence that any fuel traveled beyond it. The spill appears to have been contained and cleaned.
The cleanup personnel estimated that approximately 30 gallons of fuel were released from the truck onto
our property, based on losses reported by the truck driver.
1 thank you for your attention to this matter. Please contact me if you have any questions concerning this
incident.
Sincerely,
Troy E. Brantley
