Impact Justification and Mitigation
1.
Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
The proposed capping remedy was identified and selected based upon a detailed feasibility study. Extensive bathymetric surveying and sediment
sampling and analyses were performed to determine limits of sediment impacts, targeted areas of which are to receive capping.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
The removal of sediment will occur in the dry with the lowering of Badin Lake. A silt curtain will be installed around each construction area to minimize
sediment migration during capping activities. Appropriate sediment control techniques will be used on land to minimize sediment migration in and
around the staging area.

Hi John,
Thank you for offering to check our site for cultural resources; I enjoyed talking with you! Our project
site is located in Stanly County within the Badin Quad on the south end of Badin Lake. I've attached two
figures that outline the project area. I do have a copy of the entire Badin Quad map, but it's very large
( >20 MB). Let me know if you'd like me to send that through our FTP site as well. My phone number

Subject: RE: Badin Lake Sediment Remedial Action Plan - Narrows Reservoir, Yadkin Hydroelectric
project P -2197
Marshall:
I have reviewed the Badin Lake Sediment Remedial Action Plan - Alcoa Badin Operations, for the
Narrows Reservoir, Yadkin Hydroelectric Project P -2197.
APGI has developed a remedial action plan, and proposes to remediate low -level PCB impacted
sediments in the southern part of Badin /Narrows Lake.
Comments and Recommendations. We have no objections to the proposed remedial action plan as
described. The detail remedial action plan is very conservative in its approach to contain low -level
contaminants that are not even close to the actionable levels. The proposed remedial action with a cover
system will protect from the very low risk of potential resuspension.
The USFWS does recommend the following measures to minimize the effects of the proposed remedial
actions on fish and wildlife resources:
• Install and maintain stringent erosion - control measures where soil is disturbed through project
completion.
• Stockpile excavated material outside of the reservoir buffer.
• Leave native shoreline vegetation as unaltered as possible.
• Re- establish riparian buffers with plantings of native species wherever possible.
• Develop a Spill Prevention, Control, and Countermeasure (SPCC) Plan to describe measures to
prevent, contain, and clean up petroleum spills from any heavy equipment.

Endangered Species. Based on the information provided, our knowledge of the site, and a review of our
records, the Fish and Wildlife Service could concur with a determination that the proposed project will not
affect endangered or threatened species and their habitats. Therefore, we believe the requirements
under Section 7 of the Act are fulfilled. However, obligations under Section 7 of the Act must be
reconsidered if: (1) new information reveals impacts of this identified action that may affect listed species
or critical habitat in a manner not previously considered, (2) this action is subsequently modified in a
manner that was not considered in this review, or (3) a new species is listed or critical habitat is
determined that may be affected by the identified action.
We look forward to working with APGI to ensure that our recommendations are implemented and that
impacts to fish and wildlife resources are minimized at the Narrows Reservoir. If you have specific
questions concerning these comments, please contact me at (828) 258 -3939, ext. 227.

Subject: Agency Notification — Badin Lake Sediment Remedial Action Plan, Narrows Reservoir
Yadkin Hydroelectric Project (FERC 2197).
Dear Mr. Olson:
Biologists with the North Carolina Wildlife Resources Commission (NCWRC) have reviewed the
subject document and we are familiar with the habitat values of the area. Our comments are provided in
accordance with provisions of the Federal Power Act, as amended (16 U.S.C. 791 a -825r) and the Fish and
Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661- 667e).
Alcoa Power Generating, Inc. (APGI) proposes to install a cap over low level PCB impacted
sediments at two locations in Badin Lake (Narrows Reservoir). The sediment impacts are related to
historical stormwater discharges from the former Alcoa Badin Works facility. At each location, in -situ
containment (engineered cap) will be used consisting of a granular cap (chemical isolation component)
and armor layer (armor component). The remedial project will be completed under an Administrative
Agreement with the N.C. Department of Environment and Natural Resources.
Badin Lake is an impoundment of the Yadkin River in the Yadkin -Pee Dee River basin. Badin
Lake supports a diverse fishery including sunfish (Lepomis spp.), crappie (Pomoxis spp.), largemouth
bass (Micropterus sahuoides), catfish (Ictalurus spp.), and striped bass (Morone saxatilis). There are
records for the state threatened bald eagle (Haliaeetus leucocephalus) in the Badin Lake watershed.
According to information provided in the document, the lake's water level will be lowered
approximately 14 feet. It is anticipated the work will take approximately five weeks to complete and will
be performed during the fourth quarter of 2012. The boat ramp located adjacent to one of the project
areas will be closed and used as a staging area for equipment and materials. Boat traffic will be restricted
within the project areas. Sediment and erosion control measures will be used at the boat ramp, a silt
curtain will be installed around both project areas, and two sediment traps will be installed in Badin Lake
to collect suspended solids. A bathymetric survey and subsequent inspections will be performed to
determine effectiveness to meet the performance and design criteria.

Badin Lake Sediment Remedial Action Plan
We anticipate the proposed project will have limited impacts to aquatic and terrestrial wildlife
resources. We offer the comments or recommendations regarding the project.
Section 3.1.1.4 (p. 13): This section should include how long (e.g., days or weeks) it will take to
lower the lake to the desired level. Also, the 30 -day notification should occur prior to the start of
the drawdown.
2. If possible, we request the drawdown begin after November 11. Our staff plans to sample the
crappie fishery in Badin Lake in late October /early November of 2012.
3. We suggest signs or placards are placed at all boat ramps on the lake to inform the public of the
restricted boating areas within the lake, and to be alert to hazards due to lower water levels.
4. Section 3.1.3.1 (p. 16) indicates any sediments removed from the lake will be dewatered and/or
stabilized and moved to a designated waste management area. It appears decontamination and/or
rinse water from equipment and the materials staging area will be captured and placed into 55
gallon drums or lined roll off boxes. If not already proposed, we recommend water from any
dewatering of sediments removed from the lake also should be captured and placed into
containers.
Thank you for the opportunity to comment on this project. If we can provide further assistance,
please contact our office at (336) 449 -7625 or shari.bryantkncwildlife.org.

The above - referenced property is located in a flood zone regulated by Stanly County Planning &
Zoning. This letter will serve as a flood zone permit to allow BHE Environmental, Inc. to
perform work that will involve lowering the Badin Lake level to apply a cap system over an
approximately three acre area located in the southwest arm of Badin Lake near a former smelter.
Capping the sediments is a precaution that will stabilize the area and eliminate the possibility
that the sediments could be disturbed in the future.
Please contact us if we can be of further assistance.
