SUBJECT: Effluent Channel Visual Assessment Report for 2011 and 2012
DuPont Company — Fayetteville Works
Bladen County, North Carolina
Dear Ms. Henson:
Per the submitted 2011 Effluent Channel Visual Assessment Protocol, attached is the combined
report that describes the condition of the DuPont Company — Fayetteville Works ("DuPont")
effluent channel in 2011 prior to the removal of the site's effluent flow from the channel, and the
condition of the channel in 2012 following the removal of the site's effluent flow from the
channel.
As is consistent with the agreed upon protocol, this report has been generated as a good -faith
effort by DuPont to ensure compliance with all applicable local, state, and federal environmental
regulations, and represents the first two of a series of assessments that aims to understand the
trend of stabilization that is achieved by the construction of the new Clutfall 002 system and
subsequent flow redirection away from the effluent channel.
ASSESSMENT DESCRIPTION
The United States Department of Agriculture (`USDA") Strean, Visual Assessment Protocol was
followed to perform the two reported assessments of the DuPont effluent channel. The USDA
Protocol provides a basic level of stream health evaluation and is based primarily on physical
E.I. du Pont de Nemours and Company

conditions within the assessment area. The protocol's methodology for assessing the effluent
channel consisted of visual observations and scoring of five (5) conditions, specifically Channel
Condition, Hydrologic Alteration, Vegetation, Bank Stability, and Water Appearance.
The DuPont effluent channel's length was divided and assessments are made at nine (9)
locations, which are called "reaches" in the USDA protocol. The coordinates of the nine reaches
are used to ensure the same exact locations are assessed each year.
For each specific reach, all five of the above conditions were rated using a scoring range of 1
(worst) to 10 (best). An average score is then calculated as the overall assessment of a reach.
EXECUTIVE SUMMARY
The effluent channel's overall assessment score was 3.5 in 2011, which is rated as "Poor" in the
USDS protocol. The effluent channel's overall assessment score was 6.1 in 2012, which is rated
as "Fair" in the USDS protocol. From 2011 to 2012 there was an improvement in all assessed
conditions except for Bank Stability (see Table 1 "Assessment Summary").
A comparison of the photographs found in the report shows vegetation appearing in areas of the
channel where there had been none. It is expected that this increase of vegetation will continue
during the coming years.
It is obvious from the 2012 photographs that there was a continuous flow of water in the channel
at the time of the assessment. This was either caused by the intrusion of the surficial
groundwater into the channel or by the residual effect of rainfall runoff from storm events
preceeding the assessment. Future observations should determine if the channel has a perpetual
surface water flow to the Cape Fear River.
If you should have any questions or need additional information, feel free to call me at
[phone].
