the proposed stability berm on the downstream side of the existing Linville Dam on Lake James in Burke
County. The DWQ has determined that your application was incomplete and/or provided inaccurate
information as discussed below. The DWQ will require additional information in order to process your
application to impact protected wetlands and/or streams on the subject property. Therefore,unless we
receive the additional information requested below,we will have to move toward denial of your

receive this additional information. Please provide the following information so that we may continue to
review your project.
Additional Information Requested:
1. If there are private mitigation banks with available credit, Duke Energy will need to use them for
mitigation rather than EEP. Please acknowledge that there are no mitigation banks with available
credit.
2. The dam work is indeed exempt from Catawba rules, but the proposed sediment and erosion control
measures are not exempt in Zone 1. Additionally, please provide plans showing where on the site
the borrow will come from.
3. A number of nearby parcels were to be donated to the State as compensatory mitigation for the
FERC 401 Water Quality Certification for Catawba-Wateree. Please acknowledge that the borrow
area is not contained within the afore-mentioned parcels.
4. This Office has major concerns about dewatering a mile of the Catawba River for up to 3 months.
Please expand your discussion of this option.
