NPDES Permit Renewal Application(NPDES Permit NC0086827), Groundwater
Remediation System, Brenntag Mid-South, Inc., Durham, North Carolina.
Dear Ms. Thedford:
Date:
February 19, 2021
On behalf of Brenntag Mid-South, Inc. (Brenntag),Arcadis G&M of North Carolina,
Inc. (Arcadis)is submitting the attached National Pollutant Discharge Elimination Contact.
System(NPDES)permit renewal application for the continued discharge of effluent Jim Shilliday
from a groundwater remediation system at the Brenntag facility(former Southchem
facility)in Durham, North Carolina(NPDES Permit NC0086827). Treated Phone:
groundwater from the remediation system is discharged to an on-site storm sewer 919.415.2302
that, in turn, discharges to a drainage ditch located along the southern boundary of Email:
the site. This drainage ditch conveys surface water to an unnamed tributary of Third [e-mail]
Fork Creek. No changes have been implemented to the groundwater remediation
system since issuance of the previous NPDES Permit on November 1, 2016. our ref:
30065852
We have one requested revision to the NPDES Permit. We would like to remove
bis(2-ethylhexyl)phthalate from the required parameter list. This compound is
problematic for a variety of reasons as noted below. We reviewed the effluent results
all the way back to when we first started collecting NPDES samples in 2002, and it
does not appear that we have ever detected this compound above the current
discharge limit of 1.2 micrograms per liter(pg/L). We have included with this
submittal Table 1 which provides a summary of the treatment system effluent results
for the period of November 2016 through December 2020(the effective period of the
existing NPDES Permit). As can be seen on Table 1, bis(2-ethylhexyl)phthalate has
been detected twice during this 4 year period, and both detections were estimated
values(0.68J and 0.11J pg/L)occurring below the discharge limit of 1.2 pg/L. In
addition,the laboratory that performs all the analyses for our NPDES samples
(Eurofins TestAmerica)has detected bis(2-ethylhexyl)phthalate in the method blanks
for samples collected in the past. In communications with Eurofins TestAmerica,
they have confirmed that bis(2-ethylhexyl)phthalate is a problematic analyte. They
provided several references documenting that bis(2-ethylhexyl)phthalate can be an
artifact resulting from both sample collection and/or analysis procedures due to its
ubiquitous presence in plastics and a variety of other consumer and industrial
products. Our concern is that any future detection of bis(2-ethylhexyl)phthalate
Imagine the result

ARCADIS Ms.Wren Thedford
February 19, 2021
would most likely be an artifact of sample collection or sample analysis procedures,
and yet this is often very difficult to prove. So for the reasons noted above,we would
like to request the elimination of bis(2-ethylhexyl)phthalate)from future permit
monitoring requirements.
Please note that sludge is neither generated nor discharged by the groundwater
remediation system;therefore, a sludge management plan has not been included
with this application. Any solids(e.g. silt, iron and manganese precipitate)generated
during the groundwater extraction and/or treatment processes are filtered from the
treatment stream using bag filters and granular activated carbon units. The treated
effluent is sampled on a monthly basis for total suspended solids in accordance with
the monitoring requirements for the site.
Other items enclosed with this letter in support of the NPDES permit renewal
application include the following:
• Table 1 —summary of the effluent sampling results for a 4 year period between
January 2017 through December 2020 supporting the requested reduction of
sampling parameters discussed in this letter;
• Figure 1 - USGS topographic map of the project area that depicts the location of
the system outfall;
• Figure 2-site map that depicts the route of the treated water to the discharge
point.
If you have any questions regarding the information presented in the NPDES permit
application or any of the supporting material, please call me at(919)415-2302.

Arcadis G&M of North Carolina, Inc.
