I have attached a document from May 2009 which has the project commitments included. It appears to refer to
Mitigation for the project on Pages 5-10 with 10 probably having the impacts laid out most clearly and
referencing EEP. I also attached the special conditions from Action ID 199821203 just in case you need those as
well. I think this covers the items I had found. Let me know if you need anything else.
Thanks,
Vickie

Page 2 of 2
Our copy of the first permit mod (04-0275, v 2) lists the following total impacts for Section AA:
Riverine 0.12
Non Riverine 1.08
Total 1.20
On-Site Wetland Restoration 0.12
Mitigation required 1.08
My understanding from before was that all impacts at site 2 (which encompasses all of Section
AA) had not been accounted for. So, are the proposed impacts in addition to the previously
permitted impacts listed above?
Also, the some holds true for the stream impacts. Previously section AA permitted 11,104 feet
of stream, 0.05 acres, and 2,644 feet of mitigation was required. I'm beginning to think AA is
not the some as Site 2, even though that is what the permit application states.
Thanks.

Because the subject project lies within a Federal Energy Regulatory Commission (FERC)
licensed hydro plant project boundary (the Yadkin Project), approval for land transfer must be
obtained by NCDOT in the form of a FERC license revision. Coordination with the proper
FERC officials shall take place and the process to obtain a FERC permit will be followed
A portion of the subject project lies within the Yadkin Hydroelectric Project boundary, (Project
No. 2197), as licensed by the Federal Energy Regulatory Commission (FERC). For this reason,
NCDOT must receive prior written permission from Alcoa Power Generating, Incorporated
(APGI), before beginning construction. This permission would most likely be in the form of a
Construction Permit and/or easement, in accordance with the Yadkin Project Shoreline
Management Plan (SMP). More specifically, the Industrial Use Approval Procedures are
outlined in Appendix F to the SMP. Because the project is considered a 'new bridge or road, '
the.SMP requires 1) agency consultation, 2) 45-day prior notice to, FERC and 3) APGI written
permission (SMP Appendix F, Table 2). The Transportation Program Management Unit will
coordinate with the properAPG1 officials to obtain a FERCpermit revision for this project.

it is anticipated that the proposed widening of I-85 and interchange, reconstruction along 1-85
will encroach on one property identified as an underground storage tank (UST) site. The project
has been designed to minimise impacts to this UST site to prevent the possibility of long-term
costly remediation. This impacted site will be further evaluated before the project's construction,
Project Development and Environmental Analysis Branch
Due to its historical significance, Bridge # 46, which carries US 29-70 over the Yadkdn River in
the southbound direction, will remain in place but will be closed to vehicular traffic. The bridge
will remain in -place to serve pedestrian and bicycle traffic. Ownership, liability, and
maintenance responsibilities are currently being discussed by the Rowan and Davidson County
Commissioners, the Transportation Museum, and the State Historic Preservation Office (SHPO).
It is anticipated that these issues will be resolved before the project construction.
The issues related to ownership, liability and maintenance responsibilities have not been resolved
by the above-mentioned parties. These issues continue to be discussed by the local officials.

Rehabilitation of Bridge No. 46 (VII-Cox Bridge) is not an option due to the present state of
deterioration. After submission of the Notice ofAdverse Effect to the Council in February 2009,
FHWA entered into negotiations with NCDOT, NC HPO and other consulting parties to develop
a Memorandum of Agreement (MOA) to mitigate the effects of the project on the Yadkin River
Crossings Historic District. Davidson and Rowan Counties attended the initial meeting and
informed all parties that they may not be able to honor their original intention to take ownership
of the historic Wil-Cox Bridge. Rowan County commissioners voted against participating in
preservation of the bridge, while the Davidson County commissioners have decided to work in
good faith with FHWA and NCDOT towards taking ownership of the Vril-Cox Bridge, once the
entire M5 Yadkin River Bridge Project is completed. The ultimate fate of the bridge is unknown
at this time, but the attached MOA has been drafted to accommodate for the effects of either
outcome.

It is anticipated that thirteen Geodetic Survey markers will be impacted by this project. The
North Carolina Geodetic Survey will be contacted prior to construction regarding the relocation
of survey markers along the project.
Project Development and Environmental Analysis Branch / Structure Design Unit
Removal of Bridge # 137, which spans the Yadkin River, potentially results in 1,254 cubic yards
of temporary fill. NCDOT will implement Best Management Practices for Bridge Demolition
and Removal.
Upon further analysis of the amount of temporary fill resulting from bridge demolition, it was
determined that only the amount of fill from the substructure would result in temporaryfill The
likely potential amount of fill resulting from bridge demolition will be approximately 430 cubic
yards. NCDOT will implement Best Management Practices for Bridge Demolition and Removal.
Project Development and Environmental Analysis Branch
The project may have an impact on a low income community in the Williams Trailer Park area
located along 1-85, south of SR 2124 (Hackett Road). During the project development process,
no concerns have been raised by the public or local government officials concerning
environmental justice issues. NCDOT will aggressively seek participation of this low-income
community in the public involvement process.
NCDOT held two meetings with the citizens of the Williams Trailer Park. The first meeting was
held in the Spencer Town Hall on 6/19/2001, and the second meeting was held in the North
Carolina Transportation Museum on 6/24/2002. During these meetings, the design was
presented to the trailer park residents and their input and concerns, related to the project, were
obtained. In addition to these meetings, a more detailed analysis was performed to determine the
impacts to this area and the determination has been made that this project does not create impacts
related to Environmental Justice for the Williams Trailer Park.

PROJECT COADUTMENTS
An on site community studies review and analysis was conducted by the NCDOT Community
Studies staff on March 6, 2009. No major area development or land use changes were observed
inside the project limits since the Design Public Hearing was held.
Project Development and Environmental Analysis Branch / Design Services Unit
Based on preliminary studies, five areas were identified as possible noise barrier locations.
These noise barriers were determined to be unreasonable, due to the cost of the noise reduction
benefits versus the cost of the abatement measures. However, the proj ect will be re-evaluated for
noise abatement measures once more detailed designs are complete.
The project was re-evaluated for noise abatement measures. Noise mitigation in the form of a
wall was analyzed for several areas along the project. For the I-2304AA section, one location,
known as Barrier Location.2, it was determined that a barrier in this location is considered
reasonable and feasible by NCDOT guidelines. Hence, a noise wall is recommended in this area.
Further coordination with the affected residents and/or businesses, will take place concerning this
proposed noise wall.
One traffic noise barrier is proposed for construction on I-2304AA and is located on the west
side ofl-85, immediately south of the 1-85 Business/1-85 interchange. the projects are proposed
to be concurrently let as Design/Build. To facilitate the Design/Build process, NCDOT will
revise the existing Design Noise Reports by using the current TNMOversion 2.5 sojhvare and
incorporating the analytical results for both project sections into one report. The proposed
noise barrier is anticipated to remain. Completion of the revised NCDOT Design Noise Report
is expected in mid-May 2009.

A roadside memorial exists within the project limits; however it is not anticipated to be impacted
by this project. This memorial, dedicated in 1929 by the North Carolina Historic Commission
which currently owns the property, was investigated for its historical significance. It was
determined that the Trading Ford Monument is not eligible for the National Register of Historic
Places. Based on this site visit and other information compiled by NCDOT, no additional
archaeological work was deemed necessary for this site. The Historic Preservation Office has
requested that the bronze plaque be returned to them if the monument has to be removed during
construction. Additionally, NCDOT will coordinate with local officials and SHPO to determine
if there is a more suitable location for the marker.
According to the current plans, the roadside memorial (Trading Ford Monument) will not be
affected by the construction of this project.

In accordance with the FERC requirements, a Construction Permit will be issued to NCDOT
once all requested information is reviewed and approved by the FERC. The construction permit

will contain a condition, among many others, with regard to existing bridges that NCDOT will
be required to remove all concrete down to the existing muck line so that it will not be a hazard
or act as a "catch" for floating debris.
Project Development and Environmental Analysis Branch
The biological conclusion for the Bald Eagle was revised to "Not Likely to Adversely Affect".
This conclusion was approved by the USFWS. Because eagles may potentially nest in.this area,
NCDOT will survey for bald eagles prior to construction of the project.
As of January 31, 2008, the United States Fish and Wildlife Service lists two federally protected
species for Davidson County. Those species are the bog turtle and Schweinitz's sunflower. The
USFWS lists one federally protected species for Rowan County, which is Schweinitz's sunflower.
No new species have been added by the USFWS since the completion of the E.A. however, the
bald eagle has been delisted since then. The bald eagle was officially delisted on August 8, 2007
(CFR 50 Part 17) and is still afforded protection under the Bald and Golden Eagle Protection
Act. The biological conclusion of No Effect' remains valid for the above mentioned species.
The NCDOT Natural Environment Unit will update the project Threatened or Endangered
Species Report during the fall 2009 survey window.
Commitments Developed Through Permitting
No new special conditions were developed through the permit extension. The following
commitments are from the original permit.
Section 401 Water Quality Certifications Conditions
Division 9 Roadway Environmental Unit (REU)
Sediment and erosion control measures shall not be placed in wetlands or waters to the
maximum extent practicable. If placement of sediment and erosion control devices in wetlands
and waters is unavoidable, they shall be removed and the natural grade restored within 30 days
after the project has been released.
Division 9
Stormwater management shall be constructed in accordance with the hydraulic design plans
submitted in the February 20, 2004 application.
Hydraulic Unit
The hazardous spill catch basins (I-2304AA Plan Sheet 9)sball be designed and located to afford
ready access to maintenance and emergency response personnel and equipment.
The volume of spill containment storage provided will be approximately 10,000 gallons plus the
estimated nmoffvolume from rainfall intensity equating to a two year return period event.
I-2304A Permit Green Sheet Page 4 of 10
May 11, 2009
PROJECT COMMMVIENTS
A means will be provided such that the normal free flow of runoff at the basin outlet can be
interrupted to cause containment of hazardous runoff. This can be accomplished by providing a
mechanical control gate or by constructing a minimum control section in the outlet channel. The
mechanical gate alternative will generally be utilized in areas where normal operational activities
would allow close scrutiny and control, reducing the potential for problems with vandalism.
Maintenance plans for constructed basins shall be developed in accordance with Best
Management Practices (BMPs) and good engineering practices. Additional guidance for properly
maintaining containment basins can be found at 40 CFR Part 112, § 112.7, et at. (Spill
Prevention Control and Countermeasures).
Inspections of the hazardous spill catch basin and opening/shutting of the gate should be
performed annually at a minimum, and within six (6) months after a spill incident to ensure
integrity of the catch basin.
Repairs should occur in a timely manner.
NCDOT should provide annually, a site location map of all hazardous spill catch basins and
similar devices to Federal (USEP A, USCG), DENR, State Emergency Response Coordinator,
and all applicable county and urban center response groups. -Signage indicating the presence of a
hazardous spill catch basin shall be provided
REU. Division 9
The removal of vegetation in riparian areas should be minimized. NCDOT is encouraged to use
existing on-site vegetation and materials for stream bank stabilization and to minimize the use of
rip rap. Rip rap shall not be placed in the stream bottom. Riparian vegetation, using native trees
and shrubs, must be re-established within the construction limits of the project by the end of the
growing season following completion of construction to re-establish the riparian zone and to
provide long-term erosion control.
Division 9
Culverts that are less than 48-inch in diameter should be buried to a depth equal to or greater
than 20% of their size to allow for aquatic life passage. Culverts that are 48-incb diameter or
larger should be buried at least 12 inches below the stream bottom to allow natural stream
bottom material to become established in the culvert following installation and to provide aquatic
life passage during periods of low flow. If any of the existing pipes are perched, they shall be
removed and replaced, and re-installed correctly, unless demonstrated that this is topographically
unfeasible.
PDEA
Summary of Compensatory Mitigation: Compensatory mitigation shall be the same as that
approved by the US Army Corps of Engineers, as long as the mitigation required equals a ratio
of 1:1 restoration or creation of lost wetland acres as described in 15A NCAC 211.0506 (h)(6),
