NPDES Permit No. NC0078000

Jim Shilliday
Dear Ms. Thedford:
Phone:
919-854-1282
On behalf of Brenntag Mid-South, Inc. (Brenntag), Arcadis G&M of North Carolina,
Inc. (Arcadis) has enclosed one original and two copies of the National Pollutant E-mail:
Discharge Elimination System(NPDES)permit renewal application for the [e-mail]
continued discharge of effluent from a groundwater remediation system at the
Brenntag facility(former Worth Chemical facility) in Greensboro,North Carolina. Our ref:
Treated groundwater from the remediation system is discharged directly to an un- NC102030.0015
named tributary of South Buffalo Creek located along the eastern boundary of the
site. No significant changes have been made to the existing treatment facility since
issuance of the last permit.
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(i.e. silt, iron and manganese precipitate)generated
during the groundwater extraction process are filtered from the treatment stream
using bag filters. The existing NPDES permit for the facility does not have an
effluent monitoring requirement for suspended solids.
Other items enclosed with this letter in support of the NPDES permit renewal
application include the following:
• 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;

ARCADIS
• Attachment A—a copy of the October 2015 Discharge Monitoring Report which
summarizes the most recent analytical data for the system effluent.
If you have any questions regarding the information presented in the NPDES permit
application or any of the supporting material, please call us at [phone].
Sincerely,
Arcadis G&M of North Carolina, Inc.

Dear Sir or Madam:
Contact:
ARCADIS is pleased to submit the attached Discharge Monitoring Report (DMR) for Jim Shilliday
the month of October 2015 on behalf of Brenntag Mid-South, Inc. for the facility
located at 2 HCI Boulevard in Greensboro, North Carolina. Also attached is the Phone

the Effluent Aquatic Toxicity Report Form(Form AT-1).
Email:
During October 2015,the groundwater remediation system operated throughout the [e-mail]
month with approximately 7 days of"downtime"due to maintenance associated with
the blower unit for the groundwater remediation system's air stripper tower. A total Our ref:
of 1,066,610 gallons of water were extracted and treated by the groundwater NC102030.0015
remediation system from September 30, 2015 through October 30, 2015. As of
October 30, 2015, approximately 371,273,870 gallons of water had been extracted
and treated by the groundwater remediation system since activation of the system in
October 1992.
The pH of the effluent from the groundwater remediation system was analyzed on
October 16, 2015. The measurement indicated an effluent pH of 7.87 standard units,
which is in compliance with the stipulated range of 6 to 9 standard units.
The groundwater remediation system effluent was sampled on October 27, 2015, and
the effluent sample was analyzed for selected volatile organic compounds(VOCs)by
EPA Method 8260 as required by the NPDES permit. All parameters were in
compliance with permit requirements.
The remediation system effluent was sampled for the chronic toxicity test on October
27 and 29, 2015. The grab samples were transported on ice to Research& Analytical
Laboratories, Inc. in Kernersville, North Carolina. The samples were analyzed in
accordance with the test procedures outlined in the North Carolina Ceriodaphnia
Part of a bigger picture

ARCADIS
Chronic Effluent Toxicity Procedure(revised February 1998). The effluent samples
passed the chronic toxicity test.
As required by the NPDES permit, the remediation system effluent will be sampled
again for VOCs and chronic toxicity testing during the next quarterly sampling event
in January 2016.
If you have any questions regarding the information presented in this letter or on the
DMR,please call one of the individuals listed below.
