Subject: Draft NPDES Stormwater Permit
Permit No. NCS000543
Carus Corporation
Gaston County
Enclosed with this letter is a copy of the revised draft stormwater permit for your facility. The revisions
reflect our discussions over the past few months. Due to the changes in the draft, we are required to send it
to public notice again. Please review the draft very carefully to ensure thorough understanding of the
conditions and requirements it contains.
The revised draft permit contains the following changes from the draft sent to you on March 22, 2011:
1. The benchmark for analytical monitoring for Zinc remains unchanged in this draft permit. However,
exceedances of the Zn benchmark value will not trigger increased monitoring in Tier 2. Instead,
mandatory BMPs will be implemented as per Part II, Section E. This includes the development and
implementation of a monitoring plan for Zn. Please let us know if you have other site specific
recommendations for the BMPs in this section.
2. Please note that if any of the other parameters other than Zn trigger Tier 2, then Zn will still be part of the
overall monthly monitoring as per footnote 2 in Table 3.
Please submit any comments to me no later than thirty (30) days following your receipt of the draft.
Comments should be sent to the address listed at the bottom of this page. If no adverse comments are
received from the public or from you, this permit will likely be issued in about two months.
If you have any questions or comments concerning this revised draft permit, contact me at [phone] or

Permit No. NCS000543
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 Spill
Prevention Control and Countermeasure plan (SPCC) 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 and good housekeeping program shall be developed. The program shall list
all stormwater control systems, stormwater discharge outfalls, all on -site and adjacent
surface waters and wetlands, industrial activity areas (incl ding material storage areas,

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. The time
between this storm event and the previous storm event measuring greater than 0.1 inches must be at least
72 hours. A single storm event may have a period of no precipitation of up to 10 hours. For example, if
it rains but stops before producing any collectable discharge, a sample may be collected if the next rain
oroducin:- a discharge beeins within 10 hours.

PERMITTED DISCHARGES
SECTION A: STORMWATER POLLUTION PREVENTION PLAN
The Permittee shall develop a Stormwater Pollution Prevention Plan, herein after referred to as
the Plan. This Plan shall be considered public information in accordance with Part III, Standard
Conditions,, Section E, Paragraph 3 of this individual permit. The Plan shall include, at a
minimum, the following items:
1. Site Plan. The site plan shall provide a description of the physical facility and the
potential pollutant sources which may be expected to contribute to contamination of
stormwater discharges. The site plan shall contain ttie.following:
(a) A general location map (USGS quadrangle map or appropriately drafted
equivalent map), showing the facility!! location in relation to transportation routes
and surface waters, the name of the receiving. ter(s) to which the stormwater
outfall(s) discharges, or if the discharge is to a municipal separate storm sewer
system, the name of the municipality and the ultimate receiving waters, and
accurate latitude and longitude of the
point(s) of discharge. The general location
map (or aiternativelythe,gite�map)shall identify whether each receiving water is
impaired (on the state. s,,303(d) list of impaired waters) or is located in a
watershed for whi& a.TMDL has been established, and what the parameter(s)
of concern are.
(b)' A narrative i.scption of storage practices, loading and unloading activities,
outdoor process er as, dust or particulate generating or control processes, and
waste disposal practices. A narrative description of the potential pollutants which
could be expected to be present in the stormwater discharge from each outfall.
(c) A site map drawn to scale (including a distance legend) showing: the site property
boundary, the stormwater discharge outfalls, all on -site and adjacent surface
waters and wetlands, industrial activity areas (including storage of materials,
disposal areas, process areas, loading and unloading areas, and haul roads), site
topography, all drainage features and structures, drainage areas for each outfall,
direction of flow in each drainage area, industrial activities occurring in each
drainage area, buildings, existing BMPs, and impervious surfaces. The site map
must indicate the percentage of each drainage area that is impervious.
(d) A list of significant spills or leaks of pollutants that have occurred at the facility
during the three (3) previous years and any corrective actions taken to mitigate

Permit No. NCS000543
B, Paragraph 3. The permittee shall re -certify annually that the stormwater
outfalls have been evaluated for the presence of non-stormwater discharges.
2. Stormwater Management PIan. The stormwater management plan shall contain a
narrative description of the materials management practices employed which control or
minimize the exposure of significant materials to stormwater, including structural and
nonstructural measures. The stormwater management plan, at a minimum, shall
incorporate the following:
(a) Feasibility Study. A review of the technical 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 storage areas, materiaDhandling operations, and
manufacturing or fueling operations. In areas where elimination of exposure is
not practical, the stormwater management plan shall document the feasibility of
diverting the stormwater runoff away from,areas of potential contamination.
(b) Secondary Containment Requiremen \ebords. Secondary containment is
required for: bulk storage of liquiand Rdmatenals; storage in any amount of Section
313 of Title III of the Superfun�l Amend ern nts and Reauthorization Act (SARA)
water priority chemicals; ands'torage.in any amount of hazardous substances, in
order to prevent leaks and spills from contaminating stormwater runoff. A table
or summary of all such•t nks "and stored materials and their associated secondary
containment areas,shall be,maintained. If the secondary containment devices are
connected to stormwater conveyance systems, the connection shall be controlled
by manually activated valves or other similar devices (which shall be secured
closed with allockin&mechanism), and any stormwater that accumulates in the
containment Tea hall 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 any material. 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 years.
(c) BMP Summary. A listing of site structural and non-structural Best Management
Practices (BMP) shall be provided. The installation and implementation of BMPs
shall be based on the assessment of the potential for sources to contribute
significant quantities of pollutants to stormwater discharges and data collected
through monitoring of stormwater discharges. The BMP Summary shall include a
written record of the specific rationale for installation and implementation of the
selected site BMPs. The BMP Summary shall be reviewed and updated annually.
3. Spill Prevention and Response Plan. The Spill Prevention and Response Plan (SPRP)
shall incorporate an assessment of potential pollutant sources based on a materials
inventory of the facility. Facility personnel (or the team) responsible for implementing the
SPRP shall be identified in a written list incorporated into the SPRP and signed and dated
by each individual acknowledging their responsibilities for the plan. A responsible
Part II Page 2 of 10

r Permit No. NCS000543
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 Spill
Prevention Control and Countermeasure plan (SPCC) maybe 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 and good housekeeping program shall be developed. The program shall list
all stormwater'control systems, stormwater discharge outfalls, all on -site and adjacent
surface waters and wetlands, industrial activity areas (including material storage areas,
material handling areas, disposal areas, process areas;`loading and unloading areas, and
n P ./
haul roads), all drainage features and structures;. andVexisting structural BMPs. The
program shall establish schedules of inspections, maintenance,' and housekeeping
activities of stormwater control systems, as well as facility•equipment, facility areas, and
facility systems that present a potential for stormwater exposure or stormwater pollution.
Inspection of material handling areas and rqular cleaning schedules of these areas shall
be incorporated into the program. Timely compliance with the established schedules for
inspections, maintenance, and housekeeping shall -be recorded in writing and maintained
in the SPPP.�_.%f
Employee Training. Training`programs shall be developed and training provided at a
minimum on an annual basiss-for facility personnel with responsibilities for: spill response
and cleanup, preventative maintenance activities, and for any of the facility's operations
that have the potential;to contaminate stormwater runoff. Facility personnel (or team)
responsible for implementing the training shall be identified, and their annual training
shall be documented by -the signature of each employee trained.
6. Responsible Party: The Stormwater Pollution Prevention Plan shall identify a specific
position(s) responsible for the overall coordination, development, implementation, and
revision to the Plan. Responsibilities for.all components of the Plan shall be documented
and position assignments provided.
7. Plan Amendment. The permittee shall amend the Plan whenever there is a change in
design, construction, operation, or maintenance which has a significant effect on the
potential for the discharge of pollutants to surface waters. All aspects of the
Stormwater Pollution Prevention Plan shall be reviewed and updated on an annual
basis. The annual update shall include an updated list of significant spills or leaks of
pollutants for the previous three years, or the notation that no spills have occurred. The
annual update shall include written re -certification that the stormwater outfalls have been
evaluated for the presence of non-stormwater discharges. Each annual update shall
include a documented re-evaluation of the effectiveness of the BMPs listed in the BMP
Summary of the Stormwater Management Plan.
The Director may notify the permittee when the Plan does not meet one or more of the
minimum requirements of the permit. Within 30 days of such notice, the permittee shall
Part II Page 3 of 10

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. The time
between this storm event and the previous storm event measuring greater than 0.1 inches must be at least
72 hours. A single storm event may have a period of no precipitation of up to 10 hours. For example, if
it rains but stops before producing any collectable discharge, a sample may be collected if the next rain
producing a discharge begins within 10 hours.

Mack,
Please see the attached final draft that we plan to issue on December 19, 2011. Revisions to the second public notice
draft were made based on your additional written comments received on November 28, 2011, and our phone
conversation on December 1, 2011. We hope that you are agreeable with the changes made to address your concerns
in your letter. Those changes include the following:
We have agreed that monitoring for BOD at this facility should be removed from the permit.
Additional language was added to Part II, Section E to focus more on zinc sources attributable to the facilities
industrial activities and materials. we also added language to consider the possible effect on stormwater runoff
due to the use of reclaimed water in the cooling tower.
We decided that the benchmark for zinc should remain in the permit, as it does not trigger increased monitoring
in the Teirs. It can be used as a reference point for future sampling.
Please let me know if you have any other questions.
Thanks.

Dr. Pillai and I have reviewed your changes and appreciate once again your willingness to work with us.
The draft permit issued for our review seems to take into consideration most of the concerns we've
brought to your attention. However, we do find two areas of concern or in need of clarification.
The first concern is over BOD (biochemical oxygen demand). It had been discussed that BOD was likely
not relative to our production and was to be removed. We also submitted testing that seemingly
supported this observation. With the requirements of the BMP's and the additional Zn testing cost we
request that BOD testing be removed from the permit. —/ 6td rt.: -T. 'f-K,-,1aVm
The second concern is in section E, subpart (e.), where the requirement now seems to be monitoring
and controlling of Zn releases and exposure from industrial activities. This part is fine but the section
goes on to suggest we control for other sources of Zn contamination. This section does not read very
clear in my opinion. For example, if through our grab samples of roof drains we find elevated levels of
Zn are we required to treat for Zn that may originate from our roof and downspouts? Our roof appears
to be a standard metal roof with standard downspouts that I suspect are galvanized. This system is/was
allowed through the building codes of NC. If this type of roof and downspout system might cause
businesses to be in violation, it would seem that this type of roof should not be allowed. The cooling
tower also comes to mind as Zn emissions would not be from our process but from Zn already in the
water from the city. One final example, what of Zn in water running onto our property? With such a
tight tolerance, inbound water with small amounts of Zn may have an impact on our outbound water as
well. _ Sd .X_ No-r.L IN -,pR4P'r .)E. 4R.
While the 0.067 PPM threshold no longer triggers Tier 11 requirements, we would still like to request that
this value be removed. With considerations given to BMP's, it is well known that issues exist that might
prevent us from being under 0.067 PPM. W;> W*,NT .cd L y4 0f „u Ir �orsti' `r

In summary,�.rv►-�ortl�a.
we would like to suggest and request the following. That BOD testing be removed from theta xpt o�
requirement. That Section E subpart (e.) take into consideration only sources directly attributable to ourq K,� Rape
processes. That is, not to require further action on our part from contributions of Zn not within our
control. Or contributions not fully documented but allowed by current building codes. Consider the
elimination of the 0.067 value while we continue to investigate point source emissions and ways to
reduce Zn levels.
Thanks in advance for your consideration of the above requested changes. n? Ls a / ;?

Enclosed with this letter is a copy of the revised draft stormwater permit for your facility. The revisions
reflect our discussions over the past few months. Due to the changes in the draft, we are required to send it
to public notice again. Please review the draft very carefully to ensure thorough understanding of the
conditions and requirements it contains.
The revised draft permit contains the following changes from the draft sent to you on March 22, 2011:
1. The benchmark for analytical monitoring for Zinc remains unchanged in this draft permit. However,
exceedances of the Zn benchmark value will not trigger increased monitoring in Tier 2. Instead,
mandatory BMPs will be implemented as per Part I1, Section E. This includes the development and
implementation of a monitoring plan for Zn. Please let us know if you have other site specific
recommendations for the BMPs in this section.
2. Please note that if any of the other parameters other than Zn trigger Tier 2, then Zn will still be part of the
overall monthly monitoring as per footnote 2 in Table 3.
Please submit any comments to me no later than thirty (30) days following your receipt of the draft.
Comments should be sent to the address listed at the bottom of this page. If no adverse comments are
received from the public or from you, this permit will likely be issued in about two months.
If you have any questions or comments concerning this revised draft permit, contact me at [phone] or

Hi Robert,
Yes, Dr. Pillai and I have had a chance to look over them and we believe that the SCM permit is closer to what we had
envisioned. I also appreciate your thoughts on delaying the triggering of tiers until after the first permit year to allow us
time for sampling. While I also see that we can modify at any time, our thought was in getting something agreeable
right from the start. While on the subject of testing, I want to let you know that my time has not been spent idle since
we last met but in fact reviewing some of the samples we have managed to get. Of great interest to me, and also
mentioned, I believe by Bethany, was what impact if any might our metal roof contribute. I have some initial results out
of the down spout that are showing readings of greater than 200PPB. This sample was taken after about fifteen minutes
of light to moderate rain.
believe we would be very pleased if we could have a permit that mirrors the SCM permit of not calling out threshold
values at this juncture. I also believe that we are in a similar situation with Zn as they are with Cu. With the exception
that they seem to know or have a good idea as to potential originating sources, whereas we are still exploring all
potential Zn sources in the various waters that drain to our detention pond. The downspout sample was again a surprise
to me and I wonder how many more sources like this we might encounter. If our roof has the potential contribute this
much Zn, does our galvanized steel fence also. Since we have only taken two samples from the down spouts I still
consider the roof results somewhat inconclusive. I also plan on taking more roof samples and sending them to an
outside lab for comparison.
In summary, Dr. Pillai and I both know that we need to get something in place and we welcome this as it gives us some
direction to go in. Our suggestion at this point is a modification of the SCM permit to get us started on something
official. It is our hope that you will find our suggestion reasonable given the circumstances. And let it begin as a way to
collaborate on ways to improve, if such improvement can be accomplished.

Jeff,
I just wanted to check on the status of getting this info and additional samples.
Also, I did talk with our groundwater folks about typical background values in that area. The info/studies that they have
for that area show "background" TP levels of 0.02 to 0.2 mg/I; and Zn median level of 0.025 mg/I. This is quite a bit
lower than what is being seen from the initial sampling. Hopefully some additional sampling will help form a better idea
of what's happening at the site.
Thanks.

Jeff,
I'm still looking into all that we discussed over the phone previously regarding the monitoring in the draft permit. I do
have another question in the mean time: Do you know what the site was previously used for prior to Carus? Did the
previous activity use zinc and/or phosphorous?
One thing I stated incorrectly during that call was that the facility had to use a certified lab for the sampling. If they do
have a their own lab onsite, then they can do their own analysis as long as they are using the same methods and
procedures that a certified lab would use.
Another thing I wanted to mention is that the benchmarks for phosphorous (2 mg/L) and zinc (0.067 mg/L @ 50 mg/L
hardness) that DWQ uses are consistent with what EPA has in their MSGP for similar facilities. As a reminder, DWQ is
currently reviewing some of the metals benchmarks, including zinc. We can consider site -specific BMPs in lieu of
benchmarks for one or more of the parameters; which is consistent with 40 CPR 122.44(k)(3). This may not really apply
in this case though, since the facility has limited exposure as it is.
l feel that it would be helpful to get another sampling event to get a better feel for what's going on at the site. I would
include BOD, TP, Zn, and get a hardness value. It may be helpful to grab a sample before entering the pond, and another
at the discharge as before.

Please let me know if you have any other questions in the mean time.

Hi Robert,
We've done some quick looking and are able to say a few things about the groundwater values, but we don't have info
that's site specific to the Belmont facility.
In terms of the TP, their samples are very high and unlike typical groundwater concentrations we've seen in the area.
There's a USGS study from 2010 (http://pubs.usgs.gov/sir/2010/5176/) that discusses groundwater contributions of
phosphorus to surface water very broadly in the piedmont and their values from crystalline rocks (such as those found in
this part of the Charlotte Belt) are in the range of 0.02 mg/L. We have some data from a dairy facility about 12 miles
WNW of the site that has been in operation for dozens of years and it shows high levels of nutrients in the groundwater.
The TP values there, which we believe to be the result of the operation; are on the order of 3 to 8 mg/L downgradient
from a waste lagoon (see attached spreadsheet). Studies of the small stream that runs through the dairy were resulting
in surface water concentrations on the order of 0.4 mg/L and less. Wells that are conceivably background at the dairy
and at our Pasour Mt study site are yielding TP results that are in the range of 0.02 to 0.2 mg/L.
Their zinc values are also high. Data Joju has compiled from health department sampling of Gaston County supply wells
for zinc on the attached spreadsheet (Gaston 2006-2009 Sota) yields a median value of 0.025 mg/L. From our research
station at Pasour Mountain that's about 15 miles WNW of the site we see a bias toward higher zinc values resulting from
use of steel casing. While most supply wells in the area are constructed from PVC casing, there are also likely some that
are steel and the piping that's often used may be steel or have steel fittings, so that 0.025 may be slightly higher than
the actual ambient groundwater concentration.
In terms of contamination sites, we didn't find the Carus facility on any of the various lists. However, it's within about a
half mile of two sites that are on Superfund's NPL. The Jadco-Hughes site
(http://cfpub.epa.gov/supercpad/cursites/csitinfo.cfm?id=0403079) is to the north and the North Belmont PCE site
(http_/Lcfoub.epa.gov/supercpad/cursites/csitinfo.cfm?id=0405619) is to the northwest. I don't really know much about
either of these sites in terms of groundwater flow or concentrations of TP or zinc, but both online profiles mention
metals as contaminants of concern. There are also a couple of stray UST sites that are in that same kind of radius, but I
wouldn't expect those to contribute to TP or zinc. .
Just for reference 2L doesn't have a groundwater TP standard, but the standard for zinc is 1 mg/L.
In summary, I'd agree that there's likely some kind of contamination at the site or nearby that's resulting in those
elevated values from the springs. If you have any questions, let Joju or I know.

I'm working on a permit for a facility that produces phosphates (and zinc) for municipal water system use. They don't
like our sw benchmarks for TP=2 mg/L and Zn = 0.067 mg/L. 5o, they sent me some data and are claiming that the water
from one spring on the site has a TP of 7.08 to 15.66 mg/L, Zn of 0.09 to 0.13 mg/L and another spring that has a TP of
2.19 mg/L, Zn of 0.47 mg/L. My concern is that could these high values in the spring water be due to past contamination
at the site, or are they typical of groundwater in this area?
Any incite would be great. Thanks.

Dear Mr. Patterson:
In 2011 Carus Corporation (Carus) and Blue Ridge Geological Services, Inc. (Blue Ridge) prepared and
submitted an application for an individual permit to discharge storm water associated with industrial
activities at the subject site. On March 22, 2011 Carus received a draft permit from the NCDENR for
comment. We have reviewed the draft permit and have comments on the following items in the draft
permit:
Item 1. Analytical Monitoring Parameters Added to the Permit.
We understand that biological oxygen demand (BOD) was included in the proposed analytical
monitoring program based on the high concentration (600 mg/L) detected during our initial stormwater
sampling of Outfall OF-1 in December 2009. Blue Ridge and Carus object to including BOD in the
analytical monitoring program. The Carus facility is an inorganic chemical blending facility and does not
store, process, or ship any organic chemicals to generate any BOD from its operations. Any BOD found
in the discharge water is from one or more background sources and caused by naturally occurring organic
matter from non -point sources that are not easily identifiable. Therefore controlling BOD at the
stormwater outfall is not within the control of this facility. The proposed benchmark value of 30 mg/L in
Table 3 of the draft permit is not attainable since it is not within the control of on -site operations. In
addition, the proposed benchmark value is close to the lower detection limit of the analysis (20 mg/L).
Therefore we request that NCDENR remove BOD from the analytical monitoring requirements listed in
Table 3 of the permit.
Note - Even though they are described as benchmark values, and not as permit limits, in practice, they
serve as permit levels since if the benchmark values are exceeded, additional restrictions are imposed
such as increased monitoring and management actions as described in Tier One and Tier Two conditions
on Part I1, page 7 of 10 of the dram permit. In our opinion, these permit conditions are too onerous and
burdensome for a small facility that has less than 10 employees and operates only 9 am to 5 pm on
weekdays.

Response to Draft NPDES Permit 41VCS000543 April 2011
Carus Corporation, Belmont, NC Page 2
We. also',understand' that zinc was included in the proposed analytical monitoring program based on the
relatively high concentration (0.223 mg/L) detected during our initial stormwater sampling of Outfall OF -
IA in December 2009.• Even though the facility processes and stores zinc compounds, the zinc value in the
stormwater sample that was collected in 2009 is confounded with contributions from background sources
and is 'significantly higher than the proposed benchmark value in Table 3 of the draft permit (0.067
mg/L), assumitig-the,total' zinc value is not significantly different than the recoverable zinc. Based on
recent testing.by'""&rus personnel, we have determined that phosphorous and zinc are present at levels
above the proposed benchmark value in the tap water inside the subject facility and in several non-
stormwater discharges in the area (spring near stormwater pond, spring in creek behind pond, stream
behind stormwater pond). A map showing the nearby surface water locations is attached. Tables
summarizing the Carus analytical data is also attached. From February through April 2011 Carus
personnel collected samples at various dates and times from the tap inside the facility and from these
various surface water features. Carus personnel analyzed these water samples in their in house laboratory.
As shown on the attached table, zinc was detected in the tap water at concentrations ranging from 0.11 to
0.44 mg/L (average 0.21 mg/L) and zinc was detected in the nearby surface water features at
concentrations ranging from 0.09 to 0.80 mg/L (average 0.38 mg/L).
We understand that total phosphorous is included in the analytical monitoring program since it is a
primary potential pollutant at the facility. Again, Carus personnel collected samples of tap water and
surface water from the area and analyzed the samples. As shown on the attached tables, total
phosphorous was detected in the tap water at concentrations ranging from 0.57 to 2.28 mg/L (average
0.77 mg/L) and total phosphorous was detected in the surface water features at concentrations ranging
from 0.26 to 15.66 mg/L (average 3.62 mg(L).
The surface water samples were collected in and around the facility during a rain event and when it was
not raining. Total phosphorous was detected in most of the samples at concentrations that significantly
exceeded the proposed benchmark value in Table 3 of the draft permit. Some of the sample points are at
higher elevations than the retention pond and some are lower. None of the surface water samples had zinc
levels any lower than the proposed benchmark value (see Attachment 2). It appears that both zinc and
total phosphorous values are confounded by background including that in surface water, groundwater, and
fertilizers used by farmers/landscaping companies in the area and they do not represent the facility
contribution alone, if any in the discharge.
Carus understands that they need to monitor for both total phosphorous and total zinc. However the
benchmark values for these two constituents appear arbitrary and significantly lower than background
levels measured in the area. We propose that Carus monitor and report the values for several years and
then after evaluation of this set of data, benchmark values can be adequately determined. For monitoring
purposes, since the total zinc is not significantly different from the recoverable zinc, we request that Carus
be allowed to determine the total zinc instead of the recoverable zinc so that the analysis can be
performed at their in house laboratory instead of sending out samples to an outside laboratory which is
more expensive and burdensome.

Response to Draft NPDES Permit #NCS000543
Carus Corporation, Belmont, NC
Item 6. Vehicle Maintenance
April 2011
Page 3
Carus does not perform vehicle maintenance at this facility and therefore the related requirements do not
apply.
Item 6 of Part III of Section E. Anticipated non-compliance
Based on the discussion above, if the draft permit is issued without changes in the benchmark levels of
BOD, zinc, and total phosphorous Carus fully anticipates that values for these parameters will be above
the benchmark levels due to the confounding of background sources (tap water, surface water,
groundwater).
We appreciate your consideration of this letter and look forward to receipt of a revised permit that takes
the information in this letter into account. If you have any questions regarding this submittal or you
would like to discuss the matter, please contact the undersigned at 336-431-5454 or Mr.' Mach Cochran at
Carus at 704-822-1441.
Sincerely,
Jeff Gerlock, L.G.

Draft NPDES Stormwater Permit
Permit No. NCS000543
Carus Corporation
Gaston County
Enclosed with this letter is a copy of the draft stormwater permit for your facility. Please review the draft
very carefully to ensure thorough understanding of the conditions and requirements it contains.
The draft permit contains the following significant items for this facility -
Analytical monitoring:
1. Analytical monitoring parameters have been added to this permit. These include Zinc and BOD based on
the sampling results above the current benchmarks. TSS and pH have also been included since the
receiving stream is impaired due to these parameters. TP has been included since it is a primary potential
pollutant at this facility.
2. All analytical monitoring is set to semi-annually during a representative storm event as defined in Part II
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 are included in 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.
,t.
4. You are 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. You are responsible for all monitoring until the renewal permit is issued. See Footnote 1 of Tables 1, 4,
and 5.

6. Vehicle maintenance monitoring is performed semi-annually in order to coincide with analytical and
qualitative monitoring. This requirement appears in all individual Stormwater permits, however it only
applies to facilities that do vehicle maintenance. Ilt, time facility begins vehicle maintenance during the
permitted timeframe then the requirements shall apply.
Other permit items:
1. Guidance is provided about the Site Plan requirements. The site map must identify if the receiving
stream is impaired and if it has a TMDL established. It must also describe potential pollutants in each
outfall. 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. Requirements for the Stormwater Management Plan have been specified in Part II Section A. Details
regarding secondary containment are provided.
3. Requirements for the Stormwater Pollution Prevention Plan have been specified in Part II 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 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 is included in 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.
6. In addition to submitting two signed copies of DMRs to. Central Files, a separate signed Annual Summary
DMR copy must be submitted to the local DWQ Roo,i6; a Office by March 1 of each year.
Please submit any comments to me no later than thirty (30) days following your receipt of the draft.
Comments should be sent to the address listed at the bottom of this page. If no adverse comments are
received from the public or from you, this permit will likely be issued in about two months.
If you have any questions or comments concerning this draft permit, contact me at [phone] or

Central Office Review Summary:
1. General Observations:
• One SDO at the existing sediment pond outfall. r
• There is another sw ditch between the north of the building and the parking lot. Since it looks to be
only sw from employee parking and possible the offices, it would not be captured in the NPDES permit.
• Chemicals stored (all indoors):
a sacks of powder phosphates, zinc oxide, and zinc sulfate
o ASTs of liquid phosphate materials, phosphoric acid sodium hydroxide, zinc chloride, zinc oxide,
and zinc sulfate
• Uncovered loading/unloading of materials via the loading docks and the hose connections on the east
side of the building
• Mixing and storage indoors
• Uncovered empty tote/drum storage on asphalt pad draining to pond
Impairment: The ambient monitoring station is located in the Town of McAdenville, on the S. Fork Catawba River,
immediately upstream of where the UT discharges into the S. Fork Catawba River. The lower S. Fork Catawba
River is impaired (Cat. 5) for aquatic life due to low pH, high Turbidity, and elevated values of fecal coliform
bacteria. Elevated FCB appears to have been originating mainly from point sources with possible contributions
from nonpoint sources further upstream. Copper and Zinc levels were elevated with 8% of samples above the
standard for both parameters.
3. Threatened and Endangered: None known in the area.
4. Anal, ical Monitoring Notes: One sampling event was performed prior to submitting this new application. BOD
was extremely high (600 mg/1), which is well above the current benchmark of 30 mg/l. The other parameters
monitored were below current benchmarks for oil & grease, COD, TSS, TN and TP. pH was within the
benchmark range of 6-9 at 6.7. TP was approaching the benchmark of 2 mg/l at 1.4 mg/l. Sampling was also
performed, for phosphate and zinc. Phosphate was shown in the application as the same amount as TP. Zinc was
above the benchmark of 0.067 mg/l at 0.223 mg/1.
5. Qualitative Monitoring Notes: Will need to perform semi-annually.
Permit Recommendations: Analytical Monitoring:
1. Zinc and BOD will be added based on sampling above the benchmark, and due to the elevated values of zinc
discussed in the basinwide plan. Based on the impairment, pH and TSS will be added. Fecal will not be added
since it is not a pollutant of concern at this facility. TP will be added since it is a primary potential pollutant at
this facility.
2. All analytical monitoring has been set to semi-annually during a representative storm event as defined in Pail H
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 betaken 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.

r
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,
and 5.
6. Vehicle maintenance monitoring is semi-annually in order to coincide with analytical'and qualitative monitoring.
Other Proposed Items in the Permit:
1. Guidance is provided about the Site Plan requirements. The site map must 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. Requirements for the Stormwater Management Plan have been specified in Part II Section -A. More details
regarding secondary containment are provided.

Site inspection conducted on March 16, 2011, by Michael Parker. Initial contact was on February 25,
2001, however, a site visit could not be scheduled until the week of March 141h. Facility contact: Mr.
Mack Cochran. Facility consultant: Jeff Gerlock with Blue Ridge Environmental Services. The facility
is in the business of producing various types of phosphates that are marketed to municipal water
treatment systems for corrosion control.
This facility has applied for stormwater (SW) coverage for one outfall that drains their industrial
process area. The SW from this facility drains into a UT to the South Fork Catawba River, which is
listed as impaired for low pH, turbidity, and fecal coliform. Based on observations during the site
visit, it appears unlikely that this facility would be a contributor to any of the types of downstream
impairment. Housekeeping at this facility is excellent, and they have attempted to minimize SW
contact as much as possible. The SW drainage from the industrial process area at this site is collected
in an underground drain that has been constructed at the rear of the building. Significant measures
have been initiated to protect any potential pollutants from entering the SW drainage system. Raw
material unloading areas are outfitted with drip collection boxes, which capture any liquids used in the
manufacturing process that may spill from the hose connections or valves during off-loading. These
spillages are then manually pumped into nearby collection totes that are pumped out when they reach
their capacity. There was no evidence of past spillages or residues on the ground where the off-loading
occurs.
This facility originally submitted a SW permit application back in 2009, however, it apparently was
lost in the mail and was never received by the Division. Analytical testing of the SW from this site
performed prior to the 2009 permit submittal noted two parameters that would exceed the proposed
permit benchmark values (BOD and Zinc). The BOD was exceptionally high (600 mgll), however,
there was nothing observed during the site visit that would suggest a possible source of the high BOD
value. One possible source noted by the writer may be residues collected in the SW pond located at
the rear of the property. This pond receives all the SW that drains from the industrial process area.
During past facility operations, contaminants may have accumulated in the pond sediments and are
being washed out during rain events. It was suggest to the applicant that additional testing be
performed (including above and below the SW pond) to determine if the elevated BOD levels continue
to exist or if the source has been eliminated.
The applicant expressed some concern during the site visit with the proposed benchmark level for zinc
(0.067 mgll). Zinc is a common constituent found at this site and is used in their manufacturing
process. In spite of the best efforts of the facility staff, there is concern that consistently maintaining
the Zinc level below the proposed benchmark value may be difficult.
With the exception of a few pallets that are stored outside, there is very little in the way of actual
exposure at this facility. All spillages are collected and removed for disposal, so the only real exposure
is a few wooden pallets, a few used chemical totes, and a couple of dumpsters. With a little effort, this
facility could potentially obtain no -exposure status and eliminate the need for a SW permit. Until such
time as all exposure is eliminated, it is recommended that the subject SW permit be issued as
requested.
