Dear Mr Dreyfus:
John E. Skvarla, fli
Secretary
On April 30, 2014, Dave Parnell, of the Raleigh Regional Office of the North Carolina Division
of Energy, Mineral and Land Resources (DEMLR), conducted a compliance evaluation
inspection (CEI) at the above referenced facility. The site lies in the watershed of an unnamed
tributary (UT) to Chunky Pipe Creek, Class WS-IV, NSW waters, which lies in the Neuse River
Basin.
The following observations were noted during the NCGO80079 DEMLR inspection:
This facility processes restaurant greases, cooking down the grease mixture in order to
separate the food materials, grease and water. The food material and water is placed on wood
chips which, in turn, produces a rich soil mixture. The refined grease is shipped to another
facility for further refining to be used as fuel. Approximately 10% of the original grease
mixture results in the food material/water which is periodically place on the wood chips.
Thank you for your assistance during the inspection, it was appreciated. The inspection began
in your office, where a thorough review of the Stormwater Pollution Prevention Plan; as well
as the qualitative monitoring results, was conducted. The Stormwater Pollution Prevention
Plan has been implemented. As was discussed during the inspection, improvements to your
stormwater program could be realized if employee training and documentation of the
Stiormwater Pollution Prevention Plan annual update were provided.

overflow or outlet of the small stormwater treatment pond.

Hi Dave,
I don't remember this discussion about Carolina Biodiesel, and we don't have any paper record that I can find about
NCGO8 vs NCG06. I see that in 1993 Unity Oil was permitted under NCGO8 at this site. So, I guess they were a heating
oil distribution company, which makes sense for NCGO8.
Wait.... Maybe this is the one that started off taking in the grease/oil, straining it, and otherwise processing it a
minimum amount to clean it up and re -sell it still as essentially non-food grade oil (only suitable for French -frying at
CharGrill). But they had plans to make bio-diesel or other products as the market developed. Does that correspond
with the correspondence you saw in their file? If so, t think we left it at that time that when/if the NCG08 ever became
insufficient to address the stormwater pollution risk, we could consider what type of permit coverage to replace it with.
I think the choice at that time was whether to just switch owners of the NCGO8, or whether to issue a new NCG06 or an
NCS. 1 think we chose the low -effort path, and just processed a Name/Ownership change for this green/recycling start-
up business (at the time.)
Dave, unless you fee! that these folks are a stormwater risk that should be addressed by a permit change now, l think we
would see processing their new permit application os low priority for us over the next several months. We probably will
want to re-evaluate their permit coverage someday, but not now unless you see a significant risk. if there is no
immediate significant risk, then I think we would be content to consider that they are under permit with us, they are on
the RRO inspection schedule, they have to implement a SPPP, and they have to do visual monitoring.
Food materials -> mulch, grease -> drummed for re -sale, Process water -> probably discharged: I hope you mean to the
POTW. If there is a surface water discharge of the process water then they need a wastewater permit from our brothers
and sisters in NPDES (or they need to cease and desist immediately.)
Let us know what you think about this. If you would copy us on your inspection report, I'll file it to serve as a refresher
when/if we pull this file to investigate alternative permit coverage.

Ken, E I
I was at this facility in Durham last week and conducted an NCGO8, which does not require analytical — no
vehicle maintenance. The facility did fairly well during their inspection, SPPP, Qualitative was compliant. Their
observation monitoring point was not in an all encompassing point — and we addressed that. They did not
have a copy of the permit — but had paid their annual fees.
As l reviewed their documents, I saw some correspondences from September 2010 concerning moving them
to a permit that fits their process better - NCG06 — or possibly an individual. Do you recall any resolution to
this or is the NCGO8 the proper permit for them?
They collect used grease from restaurants and cook it down to separate the food materials, grease and water.
The food material is applied to mulch, which turns to rich "soil', and the grease is put in drums and se.nt off to
be reused as fuel. The water discharges, I think — not sure.
Any thoughts? They may be fine, just waiting for your input before writing their letter.
Thanks,

Dear Mr. Drefus:

On October 18, 2010, staff of the North Carolina Division of Water Quality, Surface Water Protection
Section, Raleigh Regional Office, conducted a compliance evaluation inspection of Carolina Biodiesel
(Green Oil), 1410 Cross Street, Durham, NC. Your assistance and cooperation was very helpful and
appreciated during the inspection process.
1. The following observations were made during the inspection:
1. This site produces a commercial level biofuel from waste vegetable oil. Marc Dreyfors is
the site Manager. The previous site was 1410 Angier Avenue. Moved from Angier Avenue
to Cross Street in June, 2009.
2. The certificate of Coverage was issued October 31, 2007 and will expire October 30, 2012.
This facility has two outfalls.
This site does not perform any vehicle maintenance and does not use 55 gallons of new
motor oil when averaged over a calendar year. Therefore, analytical monitoring associated
with vehicle maintenance not required.
4. Qualitative monitoring is required. The facility failed to conduct qualitative monitoring.
Monitoring will be performed by the site Manager.
5. The facility does provide secondary containment.
6. The Stormwater Pollutibn Prevention Plan is updated once per year, and include employee
training. The plan addresses all items as required by Part II Section A with the exception
of Part 11 Section A 2 (a) Feasibility Study.

A. Please clear a path to both outfalls. This make the discharge location safe and assessable to
monitor and sample (See attachment A).
B. Include Part 11 Section A 2 (a) Feasibility Study in your Stormwater Pollution Prevention Plan.
C. All site secondary containment areas in attachments B through F must be in compliance with
Part 11 Section A 2 (b) Secondary Containment of general permit No. NCG080000. All walls of
secondary containment must have the proper height to contain the full volume of liquid
contained.
D. Qualitative monitoring was not performed as required by Section D, Table 5. of general permit
no. NCG080000. The facility must perform qualitative monitoring.
E. Your current certificate of coverage and general permit must remain at your site at all times.
The current Certificate of Coverage (NCG080079) reflects issuance for the 1404 Angier
Avenue Site. Contact the Stormwater General Permitting Unit (807-6300) for a permit
modification in reference to the 1410 Cross Street site, Durham, NC.
Please respond to Part 11 A, B, C, D and E within thirty days of receipt of this letter. Thanks for your
