GSK Zebulon Tier I Response: High TSS Year 5 Period 1 Representative Outfall Sample NCG060105
31Mar2017 — Stormwater sample taken by Microbac labs at GSK Zebulon representative outfall. On site
pH reading of 6.8 is within parameters.
13Apr2017 — Stormwater analytical results received by GSK Zebulon from Microbac Laboratories on all
required characteristics by permit NCG060105. The TSS level of 104 mg/L exceeds the benchmark value
by 4 mg/L, triggering a Tier I response by GSK Zebulon.
24Apr2017 — Site Stormwater management inspection performed by David Schaefer, EHS Engineer, as
required by Tier I response.
Following trouble areas identified for action:
• Two storm drains within pavement east of main site energy center show that one leading to
other has high liquid level, seeming to indicate blockage. It was found later that this drain has a
sump that is lower than the connecting pipe (probably to easily capture dry weather spills ).
• Hill directly west of dust collector building shows large areas of exposed soil. Stormwater from
hill eventually leads to storm drain system within gravel area near production building.

ZrI

• Storm water outfalls west of MDPI building (series of rip -rap depressions with steel pipes) are
mostly filled with sediment. **Corrective actions identified and approved —see below.**
• Representative Outfall was very clear (unlike date of sample 31Mar17). It was identified that
the date of the sample, a nearby project to install a new manhole had caused trackout of soil
into the roadways, very close to the representative outfall. While the roads had been cleaned
since that date and may have allowed future samples to be within benchmark limits, it was
decided to still move forward with other stormwater management correction projects.
01May17 — Meeting held to share results of stormwater management inspection with contractors to
develop project plan.
07May17 — First item completed -- Edwards Inc. repaired erosion control fencing near South Admin
emergency generator project and added additional straw bales. (Complete landscaping solution
identified for hillside to be completed before end of year, after completion of project.)
***Delays for remaining projects.*** This site has complex vendor management and quote approval
processes. Multiple quotes were requested, the approval process is slow, and then the vendors would
schedule far out in advance or had to wait for other vendors (i.e. the storm drain cleaning service).
However, we were always in talks regarding projects and drove to have them all completed.

y 1�
I V

Week of 31Ju117 — Landcare adds riprap to storm drain entrance to system near gravel yard. Also, gravel
bag filters are added to storm drains within gravel yard area and contractor gravel area to prevent
sediment from entering stormwater system.
11
21Aug17 — Updated training in powerpoint format has been distributed to engineering staff, including
references to erosion control. Site is also currently arranging a site visit by Tetratech for an erosion
evaluation of the entire site.
The sum of these actions should greatly reduce the total suspended solids in storm water outfalls. In
addition, the site has much better awareness and is working harder to identify and control potential
erosion issues, particularly those related to construction projects.

Non significant dye spill — Report dated 04May2017
On 01May17, it was discovered that a pink liquid was inside of the storm drain east of the main
site energy center, just to the north of the rollup door entrance to the Chiller room. This was
documented with a photograph. As EHS was aware of a pink dye being used on site to search for water
leaks in the chill water closed loop, contact was made with CBRE to determine how the dye made its
way into the storm drain. That evening, CBRE utility technicians used a pump to remove 55 gallons of
the dyed water from the drain, finding it to not change the level much.
The CBRE maintenance manager discovered the next morning that a chill water leak was
occurring in Air Handler 90, which is positioned on the roof of the building. The air handler allows
ambient condensate to enter the storm drains on the roof, which is acceptable. However, this chill
water leak from the cooling coils was entering this very storm drain, and sending dyed water into the
storm drain on a constant basis. CBRE contacted site based contractors for an expedited repair, and
lined up Edwards Inc. to repair the leak the next morning, 03May2017. The leak in AH-90 was repaired
at approximately 12:30 pm on 03May17, which halted the leak of pink liquid into the storm drain.
The stormwater drain in question, and the stormwater drain just north of the drain outside of
the rollup door (located in the alleyway between energy center and SD Mfg) both have deep pits,
possibly to collect material like this before sending forward towards the outfall. The drain outside of the
EC rollup door has a horizontal pipe near the top of the pit that will drain south towards the series of
pipes and drains that enter site outfall #5, which is GSK's representative outfall, discharging to wetlands
on GSK property and flowing towards Worth Hinton Road. As the pits must be full to a high level before
sending water south toward the outfall, it is likely water from these pits only overfills the pits and flows
toward the outfall during rain events or massive spills / leaks. From 01May17 to 04May17, no water
flowed towards the outfall from this pits. The leak was collected into drums by CBRE using a sump
pump 02May-04May17.
The afternoon of 02May2017, Dave Schaefer EHS investigated the environmental impact of the
leak. CBRE provided an SDS of the dye used (Kingscote Chemicals — Bright Dyes Industrial Red Liquid).
This SDS showed that the dye contain 5-10% Basic Violet 10. This dye is non-biodegradeable, per an SDS
of the pure substance sourced from Sigma Chemical. However, it is also not a marine pollutant. It was
found that over the course of a year, approximately 1 gallon of this dye had been poured into the chill
water closed loop system at various times — and much of it may have entered the storm water system
from the time the leak from AH-90 had begun. After the discovery of the pink water in the storm water
drain outside of the energy center 01May17, all efforts had been made to collect the dyed water
present without discharging any more to the environment.
However, prior to 01May17, the leak was not known, and dyed water is known to have entered
the stormwater drains and pipes leading to outfall #5, and passing through the outfall into the wetlands.
A gemba of the wetlands was conducted on 02May17 by David Schaefer EHS. He viewed the water in
the shallow stream leading from the outfall, and saw a faint tinge of pink to the water. Three photos are
attached in this file, and the pink tinge is not easily noticeable without historical reference. The

surrounding soil and plant life did not show signs of staining. The level of the dye at this location is
estimated to be 5 ppm or less, conservatively. The dyed water in the storm drain was determined to be
- 50 ppm by CBRE utility technicians. The dilution of this water prior to entering outfall #5 is estimated
to be at least 10x during a measureable storm event, which is likely conservative as 3 major branches of
storm drain feed this outfall. This stream from outfall #5 combines with several other stormwater
streams before finally leaving GSK property near Worth Hinton Road. This stormwater system will
eventually join the Little River. As there are several dilutions prior to leaving GSK property, it was also
estimated that the level of dye in water leaving the GSK property is much less than 1 ppm, and is likely in
a lower concentration in ppb.
This dye is shown to not be a marine pollutant. While it is not biodegradeable, it is not
especially toxic in the environment in low concentration per SDS. It is also not a hazardous substance,
not a reportable quantity under section 311 of the Clean Water Act, nor is it in section 102 of CERCLA.
While the dye also contains a small concentration of acetic acid, the acetic acid found in this spill will be
on the same order as the dye concentration. Even if all of the dye poured exited the site at once, it
would total less than 1 lb of acetic acid, much less than the reportable quantity of 5000 lb. For these
reasons, GSK Zebulon EHS determined this spill to not meet the definition of a "Significant Spill" or "24
hour reporting" required notification to the NC Dept of Water Quality as described in section E of the
NCG060000 general wastewater permit.
This event does meet the definition of "other non-compliance" as defined in section E of the
wastewater permit, and GSK Zebulon will report this instance during the next monitoring period of July -
December 2017.

Please verify whether Qualitative Monitoring must be performed during a "representative storm
event" or "measureable storm event" (requirements vary, depending on the permit).
Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable storm event." However,
some permits do not have this requirement. Please refer to these definitions, if applicable.
I
j A "representative storm event" is a storm event that measures greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours (3 days) 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.
A "measurable storm event" is a storm event that results in an actual discharge from the
permitted site outfall. The previous measurable storm event must have been at least 72 hours
prior. The 72-hour storm interval does not apply if the permittee is able to document that a shorter
interval is representative for local storm events during the sampling period, and the permittee
obtains approval from the local DWQ Regional Office.
By this signaWre, I certify that this report is accurate and complete to the best of my knowledge:

FLAGS/NOTES AND DEFINITIONS
B The analyte was detected in the associated method blank.
D The sample was analyzed at dilution.
I The reported value is between the laboratory method detection limit (MDL) and the laboratory method
reporting limit (MRL), adjusted for actual sample preparation data and moisture content, where applicable.
U The analyte was analyzed for but not detected to the level shown, adjusted for actual sample preparation
data and moisture content, where applicable.
E The concentraton indicated for this analyte is an estimated value above the calibration range of the
instrument. This value is considered an estimate.
MRL Method Reporting Limit. The MRL is roughly equivalent to the practical quantitation limit (PQQ and is
based on the low point of the calibration curve, when applicable, sample preparation factor, dilution
factor, and, in the case of soil samples, moisture content.
N The analysis indicates the presence of an analyte for which there is presumptive evidence (85% or greater
confidence) to make a "tentative identification".
QM-02 The RPD and/or percent recovery for this QC spike sample cannot be accurately calculated due
to the high concentration of analyte inherent in the sample.
QM-12 Precision between duplicate samples was outside acceptance limits.
