1.0 INTRODUCTION
This work plan presents the stormwater sampling procedures and results for the "Feasibility Study for
Dioxin Pollution Reduction Methods" under Part II, Section "D" of the permit at the Carolina Pole
Leland site located in Leland North Carolina. Carolina Pole Leland conducted stormwater sampling
activities to evaluate the source and impacts of dioxin constituents present in stormwater at the Site.
The sampling involved the collection and analysis of stormwater samples from various locations to
assess stormwater quality for upgradient, onsite and offsite locations. The stormwater information was
collected to complete a feasibility study to evaluate remedial options for the Site. The site location is
shown in Figure 1. The site layout is provided in Figure 2.
2.0 STORM WATER SAMPLING AND ANALYSIS
In preparation for conducting the stormwater sampling, personnel familiar with the Leland Site
completed a visual inspection to determine the appropriate sampling locations to complete the Dioxin
study. The sampling locations were selected to evaluate potential impacts from areas with potential
Dioxin sources onsite, areas from upgradient properties that potentially impact stormwater quality
moving on to the Site, areas where storm water exits the Site (outfalls) and areas downgradient of the
Site. Sampling locations are shown on Figure 3 . Sample collection procedures were in accordance
with US EPA Industrial Stormwater Monitoring and Sampling Guide, 2009.
The storm event used for the sampling was large enough to create an actual discharge from the site
Particular attention to the site characteristics of low flow and high infiltration rates was considered to
select the appropriate storm event. At least 72 hours had elapsed since the last storm event at the
site.
3.0 SAMPLING PREPARATION
Preparation was essential in a climate where measurable storm events are infrequent and infiltration
rates are high such as the Leland Site. The following items were completed in advance of the
sampling.
• The lab was contacted well ahead of time to have the required sample bottles before a
measurable storm event.
• Weather forecasts were monitored to track patterns that were likely to
result in a measurable storm event.
• Monitoring personnel were identified and contacted prior to a measurable storm event.
• Sampling gear was assembled and checked for readiness, and
• Sample bottle labels were prepared using waterproof ink with the Site information.
4.0 GRAB SAMPLING PROCEDURES
The following procedures were followed for collecting the grab stormwater samples:
• Disposable powder-free gloves were worn for sampling using care not to
touch the inside of the lid or bottle.
• Samples were collected from the turbulent section in the central part of the flow without
touching the bottom or sides of the stormwater conveyance.
• Sample bottles were filled with meniscus almost to the rim by holding opening into the flow of
water without overfilling.
• Sample bottles were labeled with date, time, location, sampler's name, analysis and
preservative type.
• Samples were placed in a cooler partially filled with ice until delivered to lab.
5EM 1 KUhPILeland NC

• A completed chain-of-custody was placed in a plastic bag inside each cooler.
• Samples were delivered to the lab by Federal Express carrier.
Stormwater samples were visually assessed for the following qualitative characteristics:
• Color
• Odor
• Clarity
• Floating solids
• Settled solids
• Suspended solids
• Foam
• Oil Sheen
5.0 SAMPLE RECORDING
For each sample collected the following information was noted:
• The sample I outfall identifier
• The storm event that resulted in a discharge from the Site
• The date and duration of the event
• Rain fall measurement or estimate in inches
• Estimate of total discharge from the Site
6.0 STORMWATER ANALYTICAL RESULTS
Per the facility's permit, stormwater sampling is conducted on a semi-annual basis at the Site.
Historical analytical results are shown on Table 1. A graph of Dioxin concentration over time is shown
on Figure 4.
For the Feasibility Study, eight of the twelve proposed twelve samples were collected for laboratory
analysis. Proposed sample locations 03, 04, 07, and 08 were not sampled due to insufficient
stormwater at these locations. Each Sample collected was analyzed for Dioxins by Cape Fear
Analytical LLC using EPA Method 8290A.and copper, chromium, and arsenic by Shealy
Environmental Services, Inc using EPA Method 6010D. The analytical results are summarized on
Table 2. Complete laboratory analytical results are provided in Appendix A for metals and Appendix B
for Dioxins.
7.0 CONCLUSIONS
Results for the metals sampling reported arsenic concentrations from 0.067 mg/L to 0.31 mg/L,
chromium concentrations from 0.014 mg/L to 0.45 mg/L and copper from 0.014 mg/L to 021 mg/L all
metals results were below the required permit concentrations. Results for dioxins for TEQ WHO2005
ND=O ranged from 12.8 pg/L at sample location #12 to 3740 pg/L at sample location #6.
Metals results from the external upgradient offsite source, sample 9, show higher metal results than
outfall samples #01, #10 and #11 which indicates we are receiving metals from an outside source.
Metal results from outfalls#2, #5, and #6 where there are both internal and external sources are also
higher than the results at the permitted outfall sampling areas. Chromated Copper Arsenate (CCA)
treated material is not stored in the areas adjacent to samples#2, #5, #6 and #9.
For Dioxins, the Outfall 09 sample was collected from the northwest area of the Site which receives
surface water runoff from the adjacent property. This sample reported a concentration of Dioxin at 26.9
SEM 2 KUIP/Leland NC

pg/L for TEQ WHO 2005 ND=O. Samples from Outfall locations 02, 05 and 06 were collected from the
drainage ditches at the northwest corner of the Site which receives runoff from the adjacent property
and from the adjacent area of the Site. These samples reported TEQ WHO2005 ND=O concentrations
of 2,940 pg/L, 2430 g/L and 3,740 pg/L, respectively. Sample Outfall 10 was collected from the drainage
ditch receiving runoff from the west side of the facility and sample Outfall #11 was collected from the
drainage ditch receiving runoff from the east side of the facility, both locations just before the permitted
outfall 01. The reported TEQ WHO2005 ND=O concentrations for these locations were 178 pg/L, 13.8
pg/L and 106 pg/L, respectively. The Outfall 12 sample was collected approximately 1.1 miles
downstream of the facility and reported a concentration for TEQ WHO 2005 ND=O of 12.8 pg/L.
In any watershed there are multiple sources of pollutants including natural background levels, point
sources(e.g., wastewater treatment facilities and industry), and other non-point sources (e.g.,
agricultural lands and permitted municipalities). Background or legacy issues can affect loadings and
may not be influenced by stormwater runoff. Understanding the impact for our site of naturally
occurring pollutant levels is important. As well, it is important to understand the impact of other
sources, both point and non-point sources to determine the impact from the Leland facility.
Dioxin is mainly generated through the combustion of wood, oil, backyard burning of trash and forest
fires. Since dioxins break down slowly, as stated in the previous paragraph, legacy issues on and off
site may affect loadings. Pentachlorophenol contains a small amount of Dioxin, but the Leland site
also has a wood-fired boiler, loaders and trucks operating on site. Other potential combustion
sources include discharges from vehicles on the interstate highway adjacent to sample location#9
and discharges from locomotive traffic along the railroads on the north and east property boundaries.
In order to evaluate the dioxin results for the sampling conducted at the Site, background
concentrations need to be considered to determine the impacts from the facility and what measures
could be implemented to reduce these impacts, if any. Several attempts were made to obtain
stormwater data for areas adjacent to the Leland Facility (see attachment C) but no information was
available.
Due to the lack of additional dioxin data for the surrounding areas, we were unable to determine the
specific impact from Carolina Pole Leland and to determine a feasible measure to address the dioxin
concentrations present in stormwater at the site.
Also, it should be noted that for the four most downstream samples #1(the outfall), #10, #11 and #12
reported concentrations of 2,3,7,8-TCDD at 3.03 pg/L, 2.84 pg/L, 2.98 pg/L,and 1.99 pg/L, respectively,
all below the Safe Drinking Water Maximum Concentration Level (MCL) of 30 pg/L.

This data package was generated using an electronic data processing program referred to as
virtual packaging. In an effort to increase quality and efficiency,the laboratory has developed
systems to generate all data packages electronically. The following change from traditional
packages should be noted: Analyst/peer reviewer initials and dates are not present on the
electronic data files. Presently,all initials and dates are present on the original raw data. These
hard copies are temporarily stored in the laboratory.An electronic signature page inserted after
the case narrative will include the data validator's signature and title.The signature page also
includes the data qualifiers used in the fractional package. Data that are not generated
electronically, such as hand written pages,will be scanned and inserted into the electronic

NCS000222-Storm Water Dioxin Feasibility Study
Dear Mr. Bennett:
This letter is to request available stormwater sampling dioxin analytical data for
the areas adjacent to the Carolina Pole Mill Site in Leland,North Carolina. You
have requested the current owner,Koppers Utility and Industrial Products
(KUIP) (formally Carolina Pole Mill) to complete a Feasibility Study for potential
dioxin impacts to stormwater from the facility. KUIP is currently planning a
^ comprehensive stormwater sampling to evaluate stormwater discharge from
various areas of the Site.To evaluate the analytical results for this sampling
effort,we would like to compare the results to those you have collected from the
areas adjacent to the Site. A copy of the dioxin sampling data and sampling
locations is needed to complete the evaluation. I have been asked to assist KUIP
with this effort and am submitting this request on their behalf.
If you have any questions,please do not hesitate to contact me at
843-452-2003,or you may contact Ms.Jane House,Environmental Manager with
KUIP at 803-664-4014 or by email at HouseSI@Koppers`_com. Thank you for your
assistance with this project.We look forward to working with you.

Does DWI;do in-stream dioxin monitoring?
It seems like Koppers will have to do their own in-stream monitoring to compare the concentration of
their discharge with in-stream conditions.

Annette,
See attached request. This facility has consistently had dioxin numbers that are well above the in-
stream water quality standard so we asked them to do a feasibility study to try and determine the
source. Their consultant is asking for data that we have in the area. I'm not aware of other facilities in
this area that do dioxin monitoring and DEMLR does not collected data. We will have to check with
DWR to see if they have any monitoring data in the area I guess.

I'm not sure if they do in this particular area or not. We will have to check with them and see if they
have done any studies there. otherwise I guess the answer is that we don't have any data to pass on to
them.

Do either of your branches ever do dioxin monitoring? A facility with industrial stormwater permit
(Carolina Pole NCS000222)has high dioxin in discharge and wants to find instream dioxin data if it
exists. Thx for any info you can share.

Hi Paul,
Hope your settling in well to your new digs over at DEMLR.
Brian's out this week, but I conferred with his AMS crew and the sort answer is no,we do not have any
dioxin data.Julie Grzyb and her folks may know of any permit-specific monitoring that may be
associated with this facility, but neither of our groups out here at Reedy Creek have collected any dioxin
samples and the lab does not analyze for it.
Hope this helps.
Thanks,

Hi. This message serves as an update. As you can see from the message below,the NCDEQ-DWR lab
folks said they do not have any dioxin data, but recommended contacting NPDES permitting
folks. Some NPDES wastewater permitted facilities do instream monitoring. Normally, this monitoring
would not include dioxin, but there may be unusual circumstances when these data were
collected. Thx,
