document and a PDT meeting summary from November 29, 2007 were included in the
handouts.
2) WRF Site Selection
Presentation of WRF sites recommended for final site evaluations
Mr. Kreutzberger gave a presentation that covered the following topics: review of the
Nov. 29 PDT meeting recommendations, review of comments on previous draft
document, revised site screening results, and discussion of the next steps in the process.
Review of comments received
All numbered comments are in reference to the comment summary table included in the
handouts.
Comment No. Discussion
4 Mr. Sink expressed concern with using the distance to a highway as a
screening metric. Mr. Wicker stated that the reason for the metric is for
the safety of the residents along the secondary roads between a
highway and the proposed facilities. Ms. Goodwin stated that this
metric was used for the initial screening, but will be changed to include
more detail for the final evaluations. Mr. Sink stated that adding in the
"type of traffic" and "weight of traffic" for the final evaluations is
changing the parameter in the middle of the process, not adding more
detail for the final evaluations. Mr. Kreutzberger stated that the length
of pipe relates to other impacts and is used to represent those impacts.
Mr. Barth suggested to "agree to disagree". Mr. Wicker stated that the
metric is not just for the traffic that the road can handle, but it is also for
the safety of the residents (as discussed at the previous PDT meeting).
7 Mr. Sink stated that the SNHA is located in a small portion of the buffer
zone of Site 19 and should therefore be removed from the Site 19 area.
Ms. Goodwin stated that the screening process will start over with the
final site evaluations. Mr. Wicker said that the Wildlife Resources
Commission (WRC) is concerned with SNHA and that is why it is
included as a screening metric. Mr. Barth stated that he doesn't want a
threatened and endangered species to come up during the final
evaluations and eliminate a site. Mr. Kreutzberger stated that SNHA
could be preserved in a buffer. Mr. Barth said that he does not object to
the inclusion of SNHA in the evaluations; he just doesn't think it should
be included because it is in a buffer area. Mr. Wicker stated that the
me e,

SNHA will be included for consistency, and impacts will be eliminated
if possible during the final evaluations.
9 Mr. Sink said that there is a cemetery located on site 14. Mr. Sink said
that it was located by some residents that visit on occasion. The
cemetery is marked by deteriorating wooden markers and is several
hundred years old. Information will be requested from the State
Historic Preservation Office during the detailed site evaluations.
10 Mr. Barth stated that there are discrepancies in the Wake County Land
Use Plan with regard to structures within a half mile of the site.
Revised Intermediate Screening with the Holly Springs Effluent Pipe
Length Included
Mr. Wicker stated that the group of best -scoring sites did change when the Holly
Springs effluent pipe length was added as a screening measure. Mr. Kreutzberger
stated that the top sites are now 19, 21/23, and 30 in addition to the Partners' preferred
site. Sites 20 and 26 are the third-best sites that would be used as backup sites. Mr.
Kreutzberger stated that if a Progress Energy site cannot be acquired, then Site 21/23
would be eliminated. Site 20 is also owned by Progress Energy and would not be an
option. Therefore, Site 26 would be the backup site. Mr. Wicker said that USACE has
sent a letter to Progress Energy to inquire about land acquisition but has not received a
response. He stated that the Project Partners have been tasked to determine whether
they could legally acquire land owned by Progress Energy.
Current Project Status
Letters were sent to property owners in early January 2008. Letters were sent to the
owners of parcels included in Site 17, but Site 17 is now not included in the final sites.
Mr. Wicker stated that wetlands were delineated on three sites, are in the revision
process, and will be sent to the design teams during the week of March 3, 2008.
Wetlands will be delineated for influent and effluent pipelines in early March.
Mr. Wicker stated that the consultants will now start over with evaluations of the final
sites. The consultants will evaluate impacts based on NEPA criteria and individual
WRF layouts. All final sites will be on a level playing field. Mr. Wicker reported that
the site visits to the final sites revealed that the sites were well chosen. Generally the
sites have a few streams but not many wetlands, and they are located mostly around the
perimeter of the sites.

3) Harris Lake Discharge
Mr. Kreutzberger stated that in the past DWQ has discouraged the Project Partners from
locating the Western Wake discharge at Harris Lake. However, this option has
reemerged because of the current drought, proposed expansion of the Shearon Harris
Nuclear Power Plant, need for additional water from the Cape Fear River at the plant
during a drought.
Since the November PDT meeting, the Partners and Progress Energy have met and
discussed options regarding the Harris Lake Discharge. Both see potential benefits to a
lake discharge including: reduced length of effluent lines, potential reduced pumping
for Progress Energy in the future, and more options for water management. DWQ has
indicated that it would evaluate a lake discharge if a calibrated lake nutrient response
model was developed. The consultants have developed a modeling approach technical
memo, DWQ has submitted comments, and discussions are ongoing to address those
comments.
Mr. Sink asked if the modeling approach and comments were available to the PDT (Mr.
Lucier also requested access to this information). Ms. Haynie (CG&L) will check on
making that information available.
Mr. Bryson stated that Progress Energy is remaining neutral on the Harris Lake
discharge option. Progress Energy and DWQ are satisfied with the water quality in
Harris Lake based on monitoring over the years. Progress Energy agrees that it makes
sense to look at the available data, but they will remain neutral until they see the
modeling results. Mr. Lucier asked whether there will be an opportunity to make
formal comments on the modeling efforts. The modeling will be included in the EIS.
Mr. Barth asked how the modeling efforts will affect the overall schedule. Mr. Wicker
stated that the modeling work will be done parallel to work on the EIS. The scheduling
effects are to be determined. If the Harris Lake discharge is not an alternative, then it
will not affect the schedule. However, if it does become an alternative, scheduling
changes will have to be reassessed at that time. Ms. Goodwin said that a part of
determining the schedule depends on whether it meets the Partners' stated purpose and
need for the project, including the timing and feasibility.
Mr. Kreutzberger presented the following anticipated schedule for the Harris Lake
discharge model:
• Modeling approach - January / February 2008
• Modification of monitoring program - February 2008
• Development of watershed and lake models - February / March 2008
• Model calibration - April 2008
• Model sensitivity to discharge - May 2008

• Preliminary model report - June 2008
• Updated model analyses and reports - January 2009
Mr. Donnelly questioned whether Progress Energy's plan to use Cape Fear River water
in Harris Lake would consider the nutrients added to the lake from the Cape Fear River
water. Mr. Bailey stated that the water in the Cape Fear River is cleaner than the lake,
but this will need to be re-evaluated based on raw water and discharge data. Mr.
Kreutzberger added that model sensitivitiy and other parameters would need to be
considered. He stated that DWQ is cautious on making a decision on a potential
discharge at Harris Lake because of water quality issues.
Mr. Sink questioned whether the EIS will include a parallel evaluation of adding Cape
Fear River water to Harris Lake. Mr. Wicker stated that this evaluation will not be
included in the EIS. It will be investigated during the Nuclear Regulatory
Commission's evaluation of the Shearon Harris plant expansion. Mr. Bryson stated that
Progress Energy is moving forward with these evaluations including modeling on a
separate schedule. Mr. Barth stated that Progress Energy is also looking at installing
wells to supplement the lake. He in concerned with the impacts to groundwater levels.
Mr. Bryson stated that he had no information on this issue. Mr. Wicker stated that the
well issue would be addressed in Progress Energy's EIS for the Shearon Harris
expansion.
4) Effluent Discharge Structure
Mr. Kreutzberger presented a review of the discharge location, the SEPA document
history, design analyses, and current structure recommendations.
Discharge Location Review
The only discharge location currently authorized by DWQ is in the Cape Fear River
below Buckhorn Dam. Mr. Kreutzberger presented pictures and a description of the
proposed discharge location.
SEPA Document
DWQ initially indicated a preference for a submerged diffuser (versus a bank discharge)
in the river to provide rapid dilution. Both the SEPA EIS and PER included a diffuser
that was approximately 500 feet long, contained 100 ports and was approximately 22"
above the river bed. However, DENR agencies indicated concerns about the structure
during the SEPA EIS review. They suggested that the structure would have potential
problems with debris and would be an obstruction to boaters. The SEPA document
determined that the issue would be resolved during the design phase.

Design Analyses
The river width and the number of channels changes frequently beginning about 200
feet downstream of the dam. The discharge location was chosen to be approximately
1,800 feet downstream of the dam where the river is one channel. Rapid mixing would
occur in the river rapids downstream of the discharge location.
Two structural alternatives were evaluated: a single point discharge and a multi -point
diffuser. Mr. Kreutzberger presented a comparison of the two discharge structure
options. The final recommendation was a bank discharge because it has less
environmental impacts and maintenance as well as a lower cost. It does have less
dilution benefits compared to a multiport diffuser, but the dilution from a bank
discharge was determined to be sufficient. Mr. Sink asked if DWQ has a minimum
dilution metric. Mr. Kreutzberger responded by saying that there are water quality
standards, but no minimum requirements.
Mr. Sink asked what type of discharge structure would be used at Harris Lake. Mr.
Bailey said that it depends on the location of the discharge. If the discharge is near the
upper reaches of the lake, the discharge structure would be a bank discharge. On the
other hand, the discharge structure would be a pipe and diffuser if the location was in
the center of the lake.
5) Other Business (comments/ questions)
Mr. Wicker stated that Mr. Barth has requested a meeting with USACE and USEPA
regarding environmental justice. Mr. Wicker stated that he has talked to Becky Fox
(who is on the PDT) and Cheryl Goode of USEPA. He requested that Mr. Barth discuss
dates and potential meeting locations with him after the PDT meeting. USACE will try
to schedule this meeting within the next month. USACE, USEPA, and CG&L will
attend.
Mr. Barth asked about water and electricity lines from Apex to the WRF site. Mr.
Donnelly responded by saying that Apex is constructing a water line to the fire station
on New Hill -Holleman Road. The water line will be completed in December 2008.
Apex is simultaneously obtaining an easement for a power line, but its estimated
construction is two years from now. These projects are not related to the Western Wake
project. Mr. Wicker further clarified that any additional water lines or power lines that
will be constructed as part of, or as a result of, the Western Wake project will be
included in the EIS. Mr. Barth asked why Progress Energy was not building the power
lines, and Mr. Donnelly stated that Apex and Progress Energy are competitors in
providing electricity.

Mr. Sink requested a clarification on the Little Beaver Creek force main. Mr. Donnelly
clarified that this force main is not part of the Western Wake EIS, other than as a
secondary and cumulative impact, and it will not be built for years.
Mr. Lucier stated that Chatham County has received speculative effluent limits for a
Cape Fear discharge from DWQ. Chatham County is also working with Orange County
and Durham County on a Jordan Lake intake. He stated that Chatham County and the
Partners have not come to a final agreement on the portion of the effluent force main
that is within Chatham County. Chatham County and Cary are still discussing the
annexation issue. Chatham is working with the Partners on these issues.
