Central Office Review Summary:
1. Owner's Other Permits:
o NCO005240
2. General Observations:
o SIC Codes: This facility may have two SIC codes. From the. file it appears that the facility has a farm to
grow sage, and then they use that sage to make "clary sage oil" for perfumes, etc. The manufacturing
process fits into 2844. The farming process does not appear to fit into an SIC category. Ask applicant (see
questions.)
o Outfall Smiling: There are seven outfalls listed at the facility, and one additional outfall not numbered:
l . Outfall 1: -Sampled (representative of 2)
2. Outfall 2: Not sampled
3. Outfall 3: Sampled (representative of 6 & 7)
4. Outfall 4: Sampled
5, Outfall 5: Outfall for NC0005240, not for stormwater
6. Outfall 6: Not sampled
T. Outfall 7: Internal to site
*outfalls not sampled because they have, or think they have, representative outfall status based on a
letter submitted during the original permit review in August of 1992. 1 can find no record that this letter
had ever been addressed by DWQ, but have reviewed this representative outfall request during the
drafting of this permit. Does the WaRO have any comments on this request (see letter attached)?
3. Impairment: Salmon Creek is not listed on the 303(d) list. However, immediately downstream the Albemarle
Sound is impaired due to dioxin on the draft 2008 303(d) list; potential source is the paper mill.
4. Threatened and Endangered S ecies:
o Acipenser brevirostrum (Shortnose Sturgeon, a fish) is an endangered species (both State and
Federal) that is found in Salmon Creek, the Albemarle Sound, the lower Pasquotank River, and
Batchelor Bay. It was last observed in 1999. The accuracy of this information is considered to be
"medium" by the Natural Heritage Program (NHP).
Page 3 of 8

NCS 000134
o Threats: Construction of dams and pollution of many large northeastern river systems during the period
of industrial growth in the late 1800's and early 1900's may have resulted in substantial loss of suitable
habitat. In addition, habitat alterations from discharges, dredging or disposal of material into, rivers, or
related development activities involving estuarine/riverine mudflats and marshes, remain constant
threats. Commercial exploitation of shortnose sturgeon occurred throughout its range starting in colonial
times and continued periodically into the 1950's.
htt ://www.nmfs.noaa. oy/ r/s ecies/fish/shortnosesgLr eon.htm
o Facility's Potential Role in Exaggerating the Threats: The major potential threat from this facility is the
runoff of organic compounds. This material is not specifically listed as a threat to the sturgeon,
however, it is a perceived threat. To the best of our knowledge, the benchmarks in this permit will .
protect the species.
1. Inform the applicant in the cover letter of their permit that their facility drains to an area
where an endangered species is present, and that violation of the stormwater permit may
potentially contribute to the facility being in violation of the Threatened and Endangered
Species Act.
Figure 2: T&E Species Location in NHP Database
r..
5. Location:
o Address on file is PO Box. Found, 841 Avoca Farm Road, Merry Hill, NC 27957, on their website.
o The facility is on the borderline of draining either to the Albemarle Sound (to the east) or to Salmon
Creek (to the north). Salmon Creek (B, SW) runs along the border of the facility. The Albemarle Sound
is also (B, SW) in this area, but does not appear to be a receiving water body. However, Salmon Creek
empties into the Albemarle Sound. The sound is also not classified as a TMDL in this subbasin. The
Albemarle Sound is noted in the Basinwide Plan for this Subbasin as stressed for dioxin (due; to
WWTPs), but it is rated as "supporting" for recreation and aquatic life. The Basinwide Plan says that
the Albemarle Sound is impaired for fish consumption due to the dioxin advisory issued by DEH.
However, it is not on the 2006 303(d) list; but it is on the draft 2008 303(d) list; potential source is the
paper mill.
6. Industrial Changes Since Previous Permit: The Green Notes Process is no longer in use. The building now
houses the White Bean Process which is a water extraction of the great northern white bean which involves not
chemicals, only water.
7. Analytical Monitoring Notes:
o The previous permit required pH and COD testing. COD was consistently under the current benchmark.
pH was slightly high at outfall 4.
8. Qualitative Monitoring Notes: There are some solids issues reported (floating and suspended). They were not
prolific, however, because TSS is recommended in EPA's guidance this is of interest.

Over Current Benchmark
Data Not Collected
Revised Permit Recommendations: Analytical Monitoring:
1. Add TSS. pH and COD shall remain in the permit. Add N and P due to NSW classification of receiving stream.
2. All analytical monitoring has been set to semi-annually during a representative storm event as defined in Part 11
Section B. The permittee must also document the total precipitation for each event. If no discharge occurs
during the sampling period, the permittee must submit a monitoring report indicating "No Flow" within 30 days
of the end of the six-month sampling period. Additionally, samples must be taken a minimum. of 60 days apart,
as specified in Table 2.
3. Benchmarks for analytical monitoring have been added to this draft permit. Exceedances of benchmark values
require the permittee to increase monitoring, increase management actions, increase record keeping, and/or
install stormwater Best Management Practices (BMPs) in a tiered program. If the sampling results are above a
benchmark value, or outside of the benchmark range, for any parameter at any outfall then the facility shall
follow the Tier 1 guidelines which require a facility inspection within two weeks and implementation of a
mitigation plan within two months. If during the term of this permit, the sampling results are above the
benchmark values, or outside of the benchmark range, for any specific parameter at a specific discharge outfall
two times in a row (consecutive), then the facility shall follow the Tier 2 guidelines which require a repetition of
the steps listed for Tier 1 and also immediately institute monthly monitoring for all parameters at every outfall
where a sampling result exceeded the benchmark value for two consecutive samples.
4. The permittee is required to collect all of the analytical and qualitative monitoring samples during representative
storm events as defined in Part II Section B. Qualitative monitoring is required regardless of representative
outfall status.
5. The permittee is responsible for all monitoring until the renewal permit is issued. See Footnote 1 of Tables 1, 4,
Page 5 of 8

NCS 000134 '
and 5.
6. The flow reporting requirement has been removed per DWQ revised strategy. (The total rainfall parameter is in
this permit, however.)
7. Vehicle maintenance monitoring has been revised to semi-annually in order to coincide with analytical and
qualitative monitoring.
Other Proposed Changes to the Previous Permit:
I. Additional guidance is provided about the Site Plan requirements. The site map must now identify if the
receiving stream is impaired and if it has a TMDL established. It must also describe potential pollutants in each
outfall. The map requirements are stated more explicitly. And, the site plan must contain a list of significant
spills that have occurred in the past three years and also must certify that the outfalls have been inspected to
ensure that they do not contain non-stormwater discharges. Additional information is provided in Part II Section
A.
2. Additional requirements for the Stormwater Management Plan have been specified in Part II Section A. More
details regarding secondary containment are provided.
3. Additional requirements for the Stormwater Pollution Prevention Plan have been specified in Part H Section A.
The plan must also be updated annually to include a list of significant spills and to certify that the outfalls do not
contain non-stormwater discharges.
4. The facility must now implement a semi-annual Facility Inspection Program of the site's stormwater
management controls as specified in Part II Section A.
5. Information regarding the No Exposure Exclusion has been added to this draft permit. If industrial materials and
activities are not exposed to precipitation or runoff as described in 40 CFR § 122.26(g), the facility may qualify
for a No Exposure Exclusion from NPDES stormwater discharge permit requirements. Additional :information
is provided in Part I Section A.

Discussions with permittee: Brian Conner, 252.482.2133, 1/7/08
I . Is your facility address, 841 Avoca Farm Road, Merry Hill, NC 27957?
a. ANSWER: Yes (from www.avocainc.com/contact.asp)
2. We have a note in the file that your facility is primarily a farm for sage, which you use to manufacture "clary
sage oil" which is used in perfumes and similar products. Have there been any significant industrial changes in
your operation since your previous permit?
a. ANSWER: No changes.
3. Is your SIC code 2844 (Perfumes, Cosmetics, and Other Toiletry Preparations)?
a. ANSWER: primary is 2833, secondary is 2087
4. Does your facility produce solid residues? How? TSS is listed on EPA's General Sector Permit as analytical
parameter for SIC 2833. This was not in your previous permit's analytical testing requirements. Your qualitative
monitoring data indicate floating solids and suspended solids in some of your outfalls.
a. ANSWER: no, products are oils/liquids. Solids noted in qualitative monitoring referred to things Iike leaf
parts. The raw material (plants) is in a solid form, which is ground/processed. Suggest adding TSS.
5. What compounds at your facility would contribute to COD? Your previous testing was not high. This may have
been left in your permit following the (lengthy) discussion of analytical parameters in the..1990s. In 1994, your
company recommended a list of analytical testing parameters. This was before your landfill closed. COD was on the
list. (Discuss the option of removing this parameter with the permittee if there appears to be no concern.)
a. ANSWER: solvents used onsite... keep COD.
6. The analytical testing for pH was slightly high in half of the tests for outfall 4. Have you taken measures to correct
this issue? What have you done?
a. ANSWER: Permittee stated that that outfall is from roof runoff; not sure why there was slightly high pH
readings in the first two quarters of sampling.
7. Why were outfalls number 2 and 6 not sampled? There is a ditch near the bottom of the map. This ditch appears to
drain onto (not off of) the site. Is that correct? Or, does it drain off of the site?
a. ANSWER: Permittee stated that they have representative outfall status. Cannot find this in our files; Mr.
Conner faxed a letter from August 28, 1992 that requested this. Will address whether or not rep outfall
status granted in the draft and final permit cover letters to permittee.

Subject: Storm Water Permit Renewal
Outfall Monitoring Questions
Avoca, Inc.
Merry Hill, Bertie County, North Caroli
Permit No. NCS000134
Dear Mr. Patterson,
Avoca, Inc. applied for a Storm Water discharge permit renewal on May 5, 2004. I was
contacted by Mr. Robert Patterson of the NC Division of Water Quality on January 7,
2008 concerning the monitoring records that were submitted with the permit application.
There seems to be some questions about why certain Outfalls have been monitored while
others have not. As the descriptions below will show, a representative sample has been
taken from each Outfall area with some outfalls being grouped together.
The original permit application dated September 30, 1992 grouped several of the outfalls
together for monitoring purposes. The outfalls are grouped as follows:
1) Outfalls # 1 and #2 are grouped together and sampled at the location of Outfall # 1
due to their close proximity and overlapping of sources.
2) Outfalls #3 and #7 are also grouped together and sampled at Outfall #3 due to the
fact that field verification disclosed that runoff from both areas have the same
characteristics and share the same sources.
3) Outfall #6 is identified as a roof drain with no baseline flow from the pipe and no
process discharges on the roof of the pump house. Therefore outfall #6 was
treated as a roof _of a, storage area and exempt from the permitting process.._. ,
4) Outfall #4 includes storm drainage from some process areas as well as the boiler
room and is sampled.
✓ 5) Outfall #5 is a discharge of non -contact cooling water and is covered by NPDES
Permit No. NC0003506.
I have attached a copy of the original permit application as well as other supporting
documentation concerning the grouping of the sampling of the Outfalls. I also have
monitoring records since 1992 that follow the sampling plan as listed in the permit
application. If there are any questions concerning this matter, please contact me. AS
always, Avoca, Inc. wishes to maintain a strong relationship with the Division of Water
Quality to protect our environment.

STMJECT: MES Individual Permit Application for Stormwater Discharge
Sampling Locations
Avoca Farms,'Bertie County, NC
Dear Bill:
On behalf of RJ Reynolds Tobacco Company, we seek your approval on the following
proposed sampling locations at the Avoca Farms Facility in Bertie County, NC.
After in the field review of Avoca's underground piping and site storm drainage
maps, we feel that sampling at the following locations will give representative
( information on the sitels. stormwater runoff.
1. Sampling at CB7 and calling this "Intake 1", The ditch, marked in green,
divides the drainage area to, nOutfall #1" in half. The. eastern half is used
for farming and we would like to keep -runoff from this area separate from the
representative runoff at outfall #1.
2. Grouping outfalls #1 and #2 and sampling at outfall #1. The drainage areas
have overlapping processes_ Stormwater runoff :From the waste treatment plant
and access road to the plant is divided between outfall #1 a:ad outfall #2-
Both have chemical storage areas that are covered arnd are not directly exposed
to stormwater. Runoff from the lab and maintenance buildings, as well as the
pilot plant process will also be present iu each of these drainage areas.
3. Grouping outfalls #3 =d #7, and sampling' at CB20 (outfall 0) . Based "'on
field verificatiart, we feel that runoff from the corresponding drainage areas
will have similar characteristics. Stormwater runoff from the Clary Sage
Process is equally shared by outfalls #3 and #7. The same: access road
carrying chemicals to and from the storage areas (indoor chemical storage) is
located on both drainage areas.
4, We have identified outfall #6 as a roof drain. The area that it drains is the
roof of a pump house. There is no baseline flow from this pipe and, there are
no process discharges on the roof of this pump house, We feel that the roof
�- of this pump house can be treated as if it were the roof of a storage area,
and therefore, would be exempt from the permitting process,

Jan. 7. 2008 10:17AM AVOCA INCORPORATED Na-2082 P. 3 T
Mr. Bill Mills
August 28, 1992

5. We will also sample at outfall A, which includes storm drainage from some
process areas and the boiler room.
6. Outfall #5 is a discharge of non -contact cooling water. It is covered by
NPDES Permit No. NC0003506.
We request your concurrence with the above sampling plan.. If you have any
questions, please call me at [phone].

PART I INTRODUCTION
SECTION A: INDIVIDUAL PERMIT COVERAGE
During the period beginning on the effective date of the permit and lasting until expiration, the
permittee is authorized to discharge stormwater associated with industrial activity. Such
discharges shall be controlled, limited and monitored as specified in this permit.
If industrial materials and activities are not exposed to precipitation or runoff as described in 40

a. Feasibility Study. A review of the teclinical'and economic feasibility of changing
the methods of operations and/or storage practices to eliminate or reduce exposure
of materials and processes to stormwater, :Wherever practical, the permittee shall
prevent exposure of all storagareas, material handling operations, and
manufacturing or fueling operati6ns..jn areas where elimination of exposure is
not practical, the stormwater,manag ment plan shall document the feasibility of
diverting the storxl;mwater runoff -away from areas of potential contamination.
b. Secondary ContaiinmentiR quirements and Records. Secondary containment is
required for: bulk storage of liquid materials; storage in any amount of Section
313 of Title III "Of th 'Superfund Amendments and Reauthorization Act (SARA)
water priority chemicals; and storage in any amount of hazardous substances to
prevent leaks and spills from contaminating stormwater runoff. A table or
summary of all such tanks and stored materials and their associated secondary
containment areas shall be maintained. If the secondary containment devices are
connected directly to stormwater conveyance systems, the connection shall be
controlled by manually activated valves or other similar devices which shall be
secured closed with a locking mechanism, and any stormwater that accumulates in
the containment area shall be at a minimum visually observed for color, foam,
outfall staining, visible sheens and dry weather flow, prior to release of the
accumulated stormwater. Accumulated stormwater shall be released if found to
be uncontaminated by the material stored within the containment area. Records
documenting the individual making the observation, the description of the
accumulated stormwater and the date and time of the release shall be kept for a
period of five (5) years.
BMP Summary. A narrative description shall be provided of Best Management
Practices (BMPs) to be considered such as, but not limited to, oil and grease

inventory of the facility. Facility personnel (or team) responsible for implementing the
SPRP shall be identified. A responsible person shall be on -site at all times during :Facility
operations that have the potential to contaminate stormwater runoff through spills or
exposure of materials associated with the facility operations. The SPRP must be site
stormwater specific. Therefore, an oil SPCC plan may be a component of the SPRP, but
may not be sufficient to completely address the stormwater aspects of the SPRP. The
common elements of the SPCC with the SPRP may be incorporated by reference into the
SPRP.
4. Preventative Maintenance and Good Housekeeping Program -�A preventative
maintenance program shall be developed. The program shall document schedules of
inspections and maintenance activities of stormwater control systems, plant equipment
and systems. Inspection of material handling areas and'regular cleaning schedules of

SECTION B: ANALYTICAL MONITORING REQUIREMENTS
Analytical monitoring of stormwater discharges shall be performed as specified in Table 1. All
analytical monitoring shall be performed during a representative storm event. The required
monitoring will result in a minimum of ten analytical samplings being conducted over the term of
the permit at each stormwater discharge outfall (SDO).
A representative storm event is a storm event that measures greater than 0.1 inches of rainfall I
and that is preceded by at least 72 hours in which no storm event measuring greater than 0.1
inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation. For example, if it rains for 2 hours without producing any collectable discharge,
and then stops, a sample may be collected if a rain producing a discharge begins again within the
next 10 hours. el
