Subject: Minor NPDES Permit Modification
Alcatel -Lucent USA, Inc. — Salem Business Remediation Site
3370 Old Lexington Road
Winston-Salem, North Carolina
NPDES Permit NCO080853
Dear Mr. Weaver,
On behalf of Alcatel -Lucent USA Inc. (Alcatel -Lucent), AECOM North Carolina, Inc. (AECOM) has
prepared this letter to notify the North Carolina Department of Environment and Natural Resources
that the groundwater remediation system at the above -referenced facility has been replaced and a
minor National Pollutant Discharge Elimination System (NPDES) permit modification is hereby
requested.
Based upon a telephone conversation with you on September 26, 2011 prior to system
replacement, a major NPDES permit modification is not required in this situation because there is
no change to the following conditions: contaminants the system is treating; basic treatment
technology; permit effluent limits; and permitted outflow, location. Instead, a minor NPDES permit
modification is required and a permit modification request should be submitted after the changes to
the groundwater remediation system have been implemented. The facility's original groundwater
remediation system was permanently shut down on July 13, 2012. The new groundwater
remediation system was started on October 9, 2012.
The current NPDES permit (dated June 12, 2009) specifies that the remediation system consists of
the following components:
• Extraction wells
• Oil/water separator
• Granular media filtration
• Feed -water storage and equalization
• Parallel filtration and air -stripping treatment trains receiving segregated flow
• Activated carbon
• Solids removal (filter press)
The early 1990s design of the original remediation system was based on using parallel treatment
systems for different contaminant types, with System A receiving flow from diesel fuel extraction
wells and perimeter volatile organic compound (VOC) extraction wells, and System B receiving flow

AECOM 2
from interior VOC extraction wells. Due to the observed contaminant concentrations and flow rates
being significantly lower over the past 20 years than anticipated during the original remediation
system design, a new single -stream remediation system was designed and installed to treat
extracted groundwater. The new system consists of the following components:
• Extraction wells
• Feed -water equalization `.-•'�� `b �"
• Bag filtration
• Low profile air stripper
P PP
• Granular activated carbon
The system component list on the "Supplement to Permit Cover Sheet" portion of the NPDES
permit should be modified to reflect the new components listed above.
Please contact Erin Stewart at [phone] if you have any questions.
Yours sincerely,
OWA-&""r _/y
