Representative Outfall Status Request
NIEHS
Durham County
The Raleigh Regional Office staff have reviewed your request dated February 9, 2018 for a determination
that stormwater discharge outfall (SDO) 001 & 002 be granted representative outfall status for
stormwater outfall 003. Based on the information, maps provided and our site visit, we are approving
this request. In accordance with 40 CFR §122.21(g)(7), you are authorized to sample outfall numbers
001 & 002 as representative outfalls. This approval is effective with the next sampling event. We also
want to remind you that the permit still requires Qualitative Monitoring be performed at all SDOs,
regardless of representative status.
Please remember that any actions you initiate in response to benchmark exceedances as directed in the
tiered response provisions of your permit must address all drainage areas represented by SDO 001 &
002, where appropriate.
Please append this letter to your Stormwater Pollution Prevention Plan (SPPP) or permit to document
that representative outfall status has been approved. If changes in drainage areas, structures, processes,
storage practices, or other activities occur that significantly alter the basis of this approval,
representative outfall status may no longer be valid. You should either resume sampling at all SDOs, or
reapply to this office for representative outfall status based on updated information. If you have any
questions or comments concerning this letter, please contact me at [phone] or at
[e-mail].

Dear Sir or Madam:
Samples were collected from the three NIEHS storinwater discharge outfalls during a
representative storm event on January 28, 2018. Laboratory results for these samples are
recorded on the attached Discharge Monitoring Report (DMR) forms.
Results were less than the permitted benchmarks for all samples except those collected
for aluminum at Outfall #1 and Outfall #2. The aluminum concentration at these two
outfalls was greater than the benchmark value of 0.75 mg/L. This places Outfall #1 in
Tier 2 status and Outfall #2 in Tier 1 status.
The NIEHS plans to perform receiving water sampling, as per the 2012 NCDWQ-
approved aluminum resolution proposal, to determine whether aluminum levels at Outfall
#1 are impacting the downstream environment.
The elevated aluminum levels at these outfalls is likely due to residual sand that was
applied on the NIEHS roadways during recent winter storm events. Soil, sediment, sand,
and asphalt in central North Carolina all contain'aluminum.
Please let me know if you have any questions or would like additional information about
these analytical results. The laboratory packet is available upon request.

Samples were collected from two NIEHS stormwater discharge outfalls and three downstream
locations during a representative storm event on May 21, 2018. Laboratory results for these
samples are recorded on the attached Discharge Monitoring Report (DMR) forms.
Results were less than the permitted benchmark for aluminum at Outfall 91 and above the
benchmark at Outfall #2 as well as at all downstream locations. One sample was collected at a
location about 200 feet downstream from each associated outfalI. An additional sample was
collected at a point just after the two outfall streams merged into one flowing surface water body.
This receiving water sampling was conducted, as per the 2012 NCDWQ-approved aluminum
resolution proposal, to determine whether aluminum levels at Outfall #1 are impacting the
downstream environment. In preparation, surface roads and parking areas upstream of Outfalls
#1 and #2 were thoroughly cleaned to remove sediment and flushed with multiple rainfall events
prior to sampling. Results appear to indicate a natural source contribution to aluminum levels
since upstream outfall concentrations were less than the downstream locations.
The NIEHS has collected about 25 Tier 2 stormwater and soil samples, and performed research
to locate the aluminum source over the past 20 years. This effort revealed that our primary
aluminum sources are likely the concrete paneling on the building exteriors, flashing and sealant
installed on building rooftops, sediment from local feldspar -based soil, and sand used to treat
campus bridges during winter weather events.
We have not been able to correlate aluminum levels with rainfall intensity, time of year, or
industrial and outdoor maintenance activities. As such, the NIEHS requests that Tier II
monitoring for aluminum -be -discontinued or reduced in frequency through permit variance or
benchmark modification.
Please let me know if these changes to our aluminum sampling requirements can be approved
and if you would like additional information about these analytical results. The laboratory
packet is available upon request.

Samples were collected from the three NIEHS stormwater discharge outfalls during a
representative storm event on June 24, 2017. Laboratory results for these samples are
recorded on the attached Discharge Monitoring Report (DMR) forms.
Results were less than the permitted benchmarks for all samples except those collected
for aluminum at Outfall #1 and Outfall #3. The aluminum concentration at these two
outfalls was greater than the benchmark value of 0.75 mg/L, which places that location in
Tier 1 status. The elevated aluminum level at these outfalls is likely due to sediment
suspended in the stormwater runoff during this heavy rain event. Soil, sediment, sand,
and asphalt in central North Carolina all contain aluminum.
Please let me know if you have any questions or would like additional information about
these analytical results. The laboratory packet is available upon request.

Results for BOD were less than the permitted benchmark. As a reminder, these samples
were collected to make up for the December 18, 2016 BOD samples that were analyzed
outside of the EPA hold time due to laboratory closures for the holidays.
Please let me know if you have any questions or would like additional information about

Samples were collected from the three NIEHS stormwater discharge outfalls during a
representative storm event on December 18, 2016. Laboratory results for these samples
are recorded on the attached Discharge Monitoring Report (DMR) forms.
Results for all parameters were less than their respective benchmarks or within acceptable
ranges. The samples were delivered to the contract lab on December 19, 2016 under the
assumption that adequate time for BOD analyses was available. However, due to
laboratory closures for the holidays, the BOD analyses were conducted outside of the
EPA recommended hold time. Therefore, the NIEHS plans to collect additional BOD
samples as soon as a reasonable representative storm event occurs.
Please let me know if you have any questions or would like additional information about
these analytical results. The laboratory packet is available upon request.

Dear Sir or Madam:
Samples were collected from the three N1EHS stormwater discharge outfalls during a 1
representative storm event on July 30, 2016. -Laboratory results for these samples are
recorded on the attached Discharge Monitoring Report. (DMR) forms.
Results for all parameters were less than their respective benchmarks or within acceptable
ranges except for the aluminum concentration at Outfall.#1. The aluminum concentration
at Outfall #1 was greater than the benchmark value of 0.75 mg/L; which places that
location in Tier 1 status. The elevated aluminum level at this, outfall is likely due to
sediment suspended in the stormwater runoff during the brief'•,• -yet heavy, rain event. Soil,
sediment, sand, and asphalt in central North Carolina all contain aluminum.
Please let me -know if you have any questions or would like additional information about
these analytical results. The laboratory packet is available upon request.
Sincerely

Dear Sir or Madam:
Samples were collected from the three N1EHS stormwater discharge outfalls during a
representative storm event on December 17, 2015. Laboratory results for these samples
are recorded on the attached Discharge Monitoring Report (DMR) forms.
Results for all parameters were less than their respective benchmarks or within acceptable
ranges except for the aluminum concentration at Outfall #3. The aluminum concentration
at Outfall #3 was greater than the benchmark value of 0.75 mg/L, which places that
location in Tier 1 status. The elevated aluminum level at this outfall is likely due to
sediment suspended in the stormwater runoff during the heavy rain event.' Soil, sediment,
sand, and asphalt in central North Carolina all contain aluminum.
Please let me know if you have any questions or would like additional information about
these analytical results. The laboratory packet is available upon request.
Sincerely
William K. Steinmetz
Environmental Compliance Specialist

Samples were collected from the three NIEHS stormwater discharge outfalls during a
representative storm event on July 19, 2015. Laboratory results for these samples are
recorded on the attached Discharge Monitoring Report (DMR) forms.
Results for all parameters were less than their respective benchmarks or within acceptable
ranges. The aluminum concentration at Outfall #3 was less than the benchmark value of
0.75 mg/L for the third consecutive monthly monitoring event. Therefore, Outfall 43 is
no longer in Tier 2 status and monthly monitoring for aluminum at this location is no
longer required.
Please let me know if you have any questions or would like additional information about
these analytical results. The laboratory packet is available upon request.

A sample was collected from NIEHS stormwater discharge Outfall #3 during a
representative storm event on April 30, 2015'. Laboratory results for this sample are
recorded on the attached Discharge Monitoring Report (DMR) form.
The April aluminum level for Outfall #3 was greater than the associated benchmark
value. This is the third stormwater sample that has yielded aluminum results above the
benchmark value during the current permit term. Monthly sampling for aluminum is
continuing until three consecutive results are less than the benchmark value as per Tier 2
requirements.
The elevated aluminum levels are likely due to sand applied to road surfaces for vehicle
traction during previous winter precipitation events. As mentioned in previous
correspondence; soil, sediment, and sand in central North Carolina all contain aluminum.
Please let me know if you have any questions or would like additional information about
these analytical results. The laboratory packet is available upon request.

Dear Sir or Madam:
Samples were collected from the three NIEHS stormwater discharge outfalls during a
representative storm event on February 9, 2015. Laboratory results for these samples are
recorded on the attached Discharge Monitoring Report (DMR) forms.
Results for all parameters were less than their respective benchmarks or within acceptable
ranges except for the aluminum concentrations at Outfall # 1 and Outfall 43. The
aluminum concentration at Outfall # 1 places that location in Tier 1 status. Aluminum
concentrations at Outfall #3 have been above the benchmark value of 0.75 mglL for two,
consecutive monitoring events. Therefore, Outfall #3 is now in Tier 2 status which
triggers monthly sampling for aluminum at this location.
The elevated aluminum levels at both of these outfalls are likely due to sand applied to
road surfaces for vehicle traction during winter precipitation events. Soil, sediment, and
sand in central North Carolina all contain aluminum.
Please let me know if you have any questions or would like additional information about
these analytical results. The laboratory packet is available upon request.

to the
NIEHS stormwater permit renewal application. Laboratory analysis results for aluminum,
chemical oxygen demand, EPA method_ 624,.EPA.method 625,_are included along with field pH.
The NIEHS stormwater permit mandates analysis for these parameters during the first and last
year of the five-year permit term. This is the last year of the current stormwater permit, which
expires on June 30, 2002, The NIEHS has requested stormwater permit renewal through an
application submitted to your office on December 11, 2001.
The field pH of 7.6 was recorded at the time of sample collection, which was within 30 minutes
of the initial stormwater discharge from the representative outfall located near Building. All
parameters measured during this stormwater analysis were below their respective cut-off
concentrations with the exception of aluminum, which had a concentration of 1.11 mg/L. The
source of the elevated aluminum concentrations remains unknown. However, aluminum
concentrations have steadily decreased since annual analysis commenced at the Building 108
outfall in 1999. Rainfall data indicating 72 hours with no precipitation prior to the sampled
event is also attached for your review. Total rainfall measured by a RM Young tipping bucket
rain gauge located on NIEHS property was 1.37 inches,
Please do not hesitate to contact me at [phone] if you have any questions regarding these
stormwater analysis results or the NIEHS permit renewal application.

Qualifier Report Information
ESC recognizes and utilizes sample and result qualifiers as set forth by the EPA
Contract Laboratory Program. We firmly believe that information pertaining to
sample analysis should be made available to the ESC client. In addition to the
EPA qualifiers adopted by ESC, we have implemented ESC qualifiers to provide more
information pertaining to our analytical results. Each qualifier is designated in
the qualifier explanation as either EPA or ESC.
Definitions:
Accuracy - The relationship of the observed value of a known sample to the true
value of a known sample. Represented by percent recovery and relevant
to samples such as: control samples, matrix spike recoveries, surrogate
recoveries, etc.
Precision - The agreement between a set of samples or between duplicate samples.
Relates to how close together the results are and is represented by
Relative Percent Differrence.
Surrogate - Organic compounds that are similar in chemical composition, extraction,
and chromotography to analytes of interest. The surrogates are used to
determine the probable response of the group of analytes that are chem-
ically related to the surrogate compound. Surrogates are added to the
sample and carried through all stages of preparation and analyses.
TIC - Tentatively Identified Compound: Compounds detected in samples that are
not target compounds, internal standards, system monitoring compounds,
or surrogates.
