Subject: Graham County, NC 28 (Future US 19-74-129 Relocation), from Edwards
Gap to east of SR 1231 at Stecoah, Federal Aid Project
No. APD-12-1(22), State Project No. 8.3019122, TIP No. A-9 DD;
USACE Action ID 199930861.
The United States Environmental Protection Agency (EPA) responded with
comments in a letter dated October 15, 1999 on the public notice issued by the U. S.
Army Corps of Engineers (USACE) on September 16, 1999. These comments were in
regarded to the proposed action by the North Carolina Department of Transportation
(NCDOT) to widen NC 28 in Graham County, North Carolina from Edwards Gap to east
of SR 1231 at Stecoah.
Comment #1: "The wetland and stream impacts ... are large for a road project of 2.85
miles. The size of the wetland impact is especially troubling ... We recommend that
NCDOT minimize the impacts associated with project by considering bridging some of
the larger wetland impacts."
Response: The NCDOT understands the EPA's concern with the large amount of
impacts associated with this project. Mr. Phillip Todd of my staff met with Ms. Becky
Fox of EPA to review project related impacts on December 9, 1999. Project related
impacts were reviewed and the minimization steps implemented by the NCDOT were
discussed.
The NCDOT did not consider bridging during its NEPA planning due to its
impracticability with the existing terrain of project study area. NC 28 lies within a valley
with the floodplain of Wolf Creek on one side of the roadway and a mountain range on
2
the other side. If the NCDOT were to widen into the mountain side, thereby reducing the
impacts to waters of the United States, the cut into the mountain would be enormous.
This action would also result in additional large amounts of rock and soil to be "wasted"
thereby requiring the material to be disposed in another location. The amount of waste
generate would like require the purchase of a small valley, and therefore result in filling a
stream and any associated wetlands.
As of this letter, the NCDOT has implemented the following minimization steps
during the long history of this project:
1) Implementation of 2:1 slopes;
2) Construction of a retaining wall in areas along Wolf Creek per the comments of the
North Carolina Wildlife Resource Commission in the comments during the
Reevaluatiow6f the Final EIS for A-9 D that was signed by Federal Highway
Administration on October 31, 1995;
3) Prohibition of clearing behind the proposed retaining walls;
4) Reduction in the amount of the cut slopes into the mountains adjacent to NC 28.
The NCDOT believes that it has minimized impacts to waters of the United States
to the maximum extent practicable.
Comment #2: "The applicant proposes to mitigate for both stream and wetland impacts
losses at their Tulula Creek Wetlands Mitigation Site. Since the mitigation banking
instrument has yet been approved for this site, we recommend the permit not be issued
until the applicant has an approved banking instrument."
Response: The NCDOT initiated an umbrella Mitigation Banking Instrument (MBI)
during the summer of 1999 to establish the framework for all NCDOT mitigation sites.
Since this submission, the USACE has requested that the NCDOT pursue a site specific
MBI for Tulula and other mitigation sites. The NCDOT has been developing a draft site
specific MBI for the Tulula site. In November 1999, the USACE suggested that an MBI
may be not appropriate for the Tulula site. A decision has not been made whether this
site will be established as a bank.
Thank you for your comments on this project. If you have any questions or need
any additional information concerning this project, please contact Mr. Phillip Todd of my
staff at [phone], extension 314.

NORTH CAROLINA 401 WATER QUALITY CERTIFICATION
THIS CERTIFICATION is issued in conformity with the requirements of Section 401 Public Laws
92-500 and 95-217 of the United States and subject to the North Carolina Division of Water Quality
(DWQ) Regulations in 15 NCAC 2H, Section.0500. This modification authorizes impacts to streams
as described below.
Site Number Streams
Impacted (linear
feet) Streams
Relocated (linear
feet) Total Impact
(linear feet)
Site 5 369 715 154
Site 7 143 33 115
Site 10 213 0 213
It should be noted the modification is applicable only to the additional proposed activities. All the
authorized activities and conditions of certification associated with the original Water Quality Certification
dated November 29, 1999 and all other corresponding modifications still apply except where superceded by
this certification.
The application provides adequate assurance that the discharge of fill material into the proposed wetlands in
conjunction with the proposed development will not result in a violation of applicable Water Quality
Standards and discharge guidelines. Therefore, the State of North Carolina certifies that this activity will
not violate the applicable portions of Sections 301, 302, 303, 306, 307 of PL 92-500 and PL 95-217 if
conducted in accordance with the application and conditions hereinafter set forth.
This approval is only valid for the purpose and design that you submitted in your application, as described in
the Public Notice. Should your project change, you are required to notify the DWQ and submit a new
application. If the property is sold, the new owner must be given a copy of this Certification and approval
letter, and is thereby responsible for complying with all'the conditions. If total wetland fills for this project
(now or in the future exceed one acre, compensatory mitigation may be required as described in 15A NCAC
2H .0506 (h) (6) and (7). For this approval to remain valid, you are required to comply with all the
conditions listed below. In addition, you should obtain all other federal, state or local permits before
proceeding with your project including (but not limited to) Sediment and Erosion control, Coastal
Stormwater, Non-discharge and Water Supply watershed regulations.
Condition(s) of Certification:
1. Appropriate sediment and erosion control practices which equal or exceed those outlined in the
most recent version of two manuals. Either the "North Carolina Sediment and Erosion Control
Planning and Design Manual" or the "North Carolina Surface Mining Manual" (available from the
Division of Land Resources in the DEHNR Regional or Central Offices). The control practices
shall be utilized to prevent exceedances of the appropriate turbidity water quality standard (50
NTUs in all fresh water streams and rivers not designated as trout waters; 25 NTUs in all lakes
and reservoirs, and all saltwater classes; and 10 NTUs in trout waters);
2. All sediment and erosion control measures placed in wetlands or waters shall be removed and
the natural grade restored after the Division of Land Resources has released the project;
3. Measures shall be taken to prevent live or fresh concrete from coming into contact with
waters of the state until the concrete has hardened;
4. There shall be no excavation from or waste disposal into jurisdictional wetlands or waters
associated wide this permit without appropriate modification of this permit. Should waste or
borrow sites be located in wetlands or stream, compensatory mitigation will be required since it is
a direct impact from road construction activities;
5. The additional stream impacts of 184 linear feet will be mitigated at a ratio of 1:1 at the Tulula
Creek Mitigation Site in Graham County. All other mitigation requirements associated with the
original 401 Water Quality Certification dated November 29, 1999 still apply.
6. All other conditions written into previous Water Quality Certifications for this project still apply.
Violations of any condition herein set forth shall result in revocation of this Certification and may result in
criminal and/or civil penalties. This Certification shall become null and void unless the above conditions
are made conditions of the Federal 404 and/or coastal Area Management Act Permit. This Certification
shall expire upon expiration of the 404 or CAMA permit.
If this Certification is unacceptable to you have the right to an adjudicatory hearing upon written request
within sixty (60) days following receipt of this Certification. This request must be in the form of a written
petition conforming to Chapter 150B of the North Carolina General Statutes and filed with the Office of
Administrative Hearings, P.O. Box 27447, Raleigh, N.C. 27611-7447. If modifications are made to an
original Certification, you have the right to an adjudicatory hearing on the modifications upon written
request within sixty (60) days following receipt of the Certification. Unless such demands are made, this
Certification shall be final and binding.

DWQ No. 000529; T.I.P. No. A-9DD.
Dear Mr. Gilmore:
The Division of Water Quality has reviewed your submittal for a 401 Water Quality Certification for the
aforementioned project. Review of your application revealed it lacking necessary information required for
making an informed permit decision. The permit application was deficient in the following areas:
The proposed mitigation references use of the Tulula Creek Mitigation Site. As you are aware, this site
does not, at present, have a 401 Water Quality Certification. Therefore, until the issues associated with the
site are resolved we cannot accept the site as appropriate mitigation for wetland or stream impacts.
Therefore, pursuant to 15A NCAC 2h .0507(a)(4), we will have to place the permit application on hold until
we are supplied the necessary information. Furthermore, until the information is received by the NC
Division of Water Quality, we request (by copy of this letter) that the US Army Corps of Engineers place
the permit application on hold.
Hopefully, we can work to-ether to expedite the processing of your permit application. If you have any
questions or require additional information, please contact John Hennessy at 919-733-5694.

Subject: Graham County, NC 28 (Future US 19-74-129 Relocation), from Edwards
Gap to east of SR 1231 at Stecoah, Federal Aid Project
No. APD-12-1(22), State Project No. 8.3019122, TIP No. A-9 DD;
USACE Action Id 199930861; WQC Project # 990414; USFWS
Log # 4-2-96-022.
Dear Sir:
As you are aware, the North Carolina Department of Transportation submitted a
Section 404 Individual Permit (IP) application in a letter dated April 20, 1999. The
proposed action involves widening and realigning NC 28 in Graham County, from
Edwards Gap to east of SR 1231 at Stecoah. The U. S. Army Corps of Engineers
(USACE) placed the proposed action by NCDOT on public notice September 16, 1999
(USACE Action Id 199930861). In a letter dated October 29, 1999, the USACE
forwarded comments from resource agencies, particularly those from the U. S.
Environmental Protection Agency (EPA), N. C. Wildlife Resources Commission
(NCWRC) and U. S. Fish and Wildlife Service (USFWS), and asked for the NCDOT's
response to these comments.
Response to Comments from EPA
Specifically, the USACE asked that the NCDOT respond directly to EPA in
regard to its concerns with the subject action. The NCDOT met with the EPA on site to
discuss and review the project. A response to EPA's comments was provided in a letter
dated December 23, 1999.
t
Changes in Impacts to waters of the United States
A copy of revised permit drawings is attached to this letter. As the NCDOT has
finalized roadway design plans for the project, impacts to waters of the United States
have changed at four sites; Site 5, 7, 10 and 11. Site 11 involves a reduction in the
wetland impact from 1.48 acres in the permit application to 1.43 acres, a reduction of
0.05 acre.
Revisions at Site 5, 7 and 10 are associated with stream impacts. At Site 5, the
amount of existing channel impact remains 869 feet, although the amount of relocated
channel has decreased from 741 feet to 715 feet. The channel loss at this site is now 154
feet.
At Site 7 and 10, the amount of existing channel impacted has increased. At Site
7, the impact has increased from 66 feet to 148 feet. It was noted that Table 2 of the
permit application listed this impact as relocation only when in fact it should have been
channel loss and relocation. There will be 33 feet of channel relocation at this site. The
channel loss at this site is 133 feet.
At Site 10, the impact to existing channel has increased from 144 feet to 213 feet.
Therefore, the channel loss associated with this site is now 213 feet.
Response to Comments from Resource Agencies
The NCDOT has reviewed the comments provided by the resource agencies. The
NCDOT believes that it can comply with comments from the NCWRC as special
conditions, although comment #9 needs to be modified. The NCDOT suggests that this
comment be modified to state "Stormwater should be directed to buffer areas or retention
basins, as much as possible and practicable, to avoid routing it directly into streams".
The NCDOT has investigated this concern of the NCWRC, an issue that was also
raised by the USFWS on page 2 of its comments. The NCDOT has taken the following
measures in response to comment #9 from the NCWRC and USFWS to avoid routing
stormwater directly into streams by providing a buffer. Table 1 indicates the station
numbers that buffers between the stormwater discharge and the stream have been
incorporated.

As mentioned in the permit application to the Department of the Army, the
NCDOT has designed the stream relocations using natural stream techniqueq that
includes a mimic of slope, riffle slope, pool slope, etc. to resemble the existing stream
conditions as detailed by the NCWRC, item #5 and by the USFWS, item #3 on page 3. A
copy of stream data from the reference reach and proposed reach was included with
permit drawings of the original Section 404 permit application. The NCDOT is also
providing a copy to Mr. Micky Clemmons of the NCWRC.
The NCDOT has considered the comment for the USFWS regarding riparian
vegetation, Item #1 on page 3. The NCDOT will revegetate stream relocation areas with
similar species. A typical of the revegetation plan is attached to this letter, and this
typical also includes the species to be planted.
On page 3, item #2, the USFWS expressed a desire to inspect stream segments
prior to water diversion. The NCDOT has committed to constructing relocated channels
as depicted on the attached permit drawings that constitutes appropriate review prior to
construction. The NCDOT will make an effort to contact the USFWS to inspect the
stream relocated channel prior to water diversion. However, the NCDOT does not
believe it reasonable nor practicable to cease work on the project until the USFWS
inspects completed work. If a representative desires to the review the stream relocation,
the representative should contact the NCDOT Resident Engineer for the project to
arrange for a site visit.
The USFW suggest§ that the NCDOT monitor channel construction for five (5)*
years and submit annual reports to the resource agencies. The NCDOT believes that twa
(2) years of monitoring is sufficient. The NCDOT bases this belief that it is highly likely
that "stream forming" storm events will occur within this two-year period.
As noted in the letter transmitting comments from the public notice, all of the
responding agencies recommended that no Department of the Army permit be issued
until a mitigation banking agreement is developed for the Tulula Creek Mitigation Bankr
The NCDOT initiated an umbrella Mitigation Banking Instrument (MBI) during the
summer of 1999 to establish the framework for all NCDOT mitigation sites. Since this
submission, the USACE has requested that the NCDOT pursue a site specific MBI for
Tulula and other mitigation sites. The NCDOT has been developing a draft site specific
Response to Comments on Public Notice
TIP No. A-9 DD

V
MBI for the Tulula site. In November 1999, the USACE suggested that an MBI may not
be appropriate for the Tulula site. A decision has not been made whether this site will be
established as a bank.
If the Tulula site is not used as a bank, the NCDOT believes that the site will
provide sufficient mitigation for both wetland and stream impacts. The NCDOT has
begun construction of the mitigation site, and plans to complete construction during the
summer of 2001. The NCDOT has not initiated a search in the drainages suggested by
the USFWS because it believes that the Tulula site provides sufficient mitigation for
project related impacts. The NCDOT appreciates the USFWS's suggestion that the
NCDOT investigate mitigation opportunities in these two drainages and will consider this
suggestion in its mitigation search for the future sections of TIP No. A-9.
The NCDOT agrees with the USFWS's determination that the recent discovery of
the Indiana bat (Myotis sodalis) in western North Carolina necessitates greater evidence
to support the biological conclusion of "No effect" for the species (USFWS, page 4) that
was included in the Reevaluation of the Final EIS for TIP No. A-9D. The NCDOT
submitted the Section 404 permit application prior to this species' discovery during the
summer of 1999. The NCDOT is working to resolve this issue and tentatively plans to
conduct surveys for the bat during the spring/ summer of 2000. The NCDOT will
provide a copy of the survey results and subsequent biological conclusion to the USFWS
and USACE.
Modification of 401 Water Quality Certification (WQC) is also necessary due to
the changes in impacts to wetlands and streams described earlier in this letter. The
NCDOT requests that the N. C. Division of Water Quality modify the existing 401 WQC
to include these changes. A check for this modification has been attached.
In summary with regard to project impacts to waters of the United States,
construction of TIP No. A-9 DD will result in the fill of 6.86 acres of wetlands, in
excavation of 1.14 acres of wetlands, mechanized clearing of 0.62 acres of wetlands and
0.02 acre of drained wetlands. The project will impact 3.77 acres of surface water and
5,621 feet of stream. Of this amount, 4,014 feet of stream will be relocated using natural
stream channel design techniques in the hydraulic planning. There will be 1,607 feet of
stream loss from project construction.

Subject: Graham County, NC 28 (Future US 19-74-129 Relocation), from Edwards
Gap to east of SR 1231 at Stecoah, Federal Aid Project
No. APD-12-1(22), State Project No. 8.3 019122, TIP No. A-9 DD;
USACE Action Id 199930861; WQC Project # 990414; USFWS
Log # 4-2-96-022.
Dear Sir:
As you are aware, the North Carolina Department of Transportation submitted a
Section 404 Individual Permit (IP) application in a letter dated April 20, 1999. The
proposed action involves widening and realigning NC 28 in Graham County, from
Edwards Gap to east of SR 1231 at Stecoah. The U. S. Army Corps of Engineers
(USACE) placed the proposed action by NCDOT on public notice September 16, 1999
(USACE Action Id 199930861). In a letter dated October 29, 1999, the USACE
forwarded comments from resource agencies, particularly those from the U. S.
Environmental Protection Agency (EPA), N. C. Wildlife Resources Commission
(NCWRC) and U. S. Fish and Wildlife Service (USFWS), and asked for the NCDOT's
response to these comments.
Response to Comments from EPA
Specifically, the USACE asked that the NCDOT respond directly to EPA in
regard to its concerns with the subject action. The NCDOT met with the EPA on site to
discuss and review the project. A response to EPA's comments was provided in a letter
dated December 23, 1999.
P.O. BOX 25201, RALEIGH, N.C. 27611-5201
March 27, 2000

Changes in Impacts to waters of the United States
A copy of revised permit drawings is attached to this letter. As the NCDOT has
finalized roadway design plans for the project, impacts to waters of the United States
have changed at four sites; Site 5, 7, 10 and 11. Site 11 involves a reduction in the
wetland impact from 1.48 acres in the permit application to 1.43 acres, a reduction of
0.05 acre.
Revisions at Site 5, 7 and 10 are associated with stream impacts. At Site 5, the
amount of existing channel impact remains 869 feet, although the amount of relocated
channel has decreased from 741 feet to 715 feet. The channel loss at this site is now 154
feet.
At Site 7 and 10, the amount of existing channel impacted has increased. At Site
7, the impact has increased from 66 feet to 148 feet. It was noted that Table 2 of the
permit application listed this impact as relocation only when in fact it should have been
channel loss and relocation. There will be 33 feet of channel relocation at this site. The
channel loss at this site is 133 feet.
At Site 10, the impact to existing channel has increased from 144 feet to 213 feet.
Therefore, the channel loss associated with this site is now 213 feet.
Response to Comments from Resource Agencies
The NCDOT has reviewed the comments provided by the resource agencies. The
NCDOT believes that it can comply with comments from the NCWRC as special
conditions, although comment #9 needs to be modified. The NCDOT suggests that this
comment be modified to state "Stormwater should be directed to buffer areas or retention
basins, as much as possible and practicable, to avoid routing it directly into streams".
The NCDOT has investigated this concern of the NCWRC, an issue that was also
raised by the USFWS on page 2 of its comments. The NCDOT has taken the following
measures in response to comment #9 from the NCWRC and USFWS to avoid routing
stormwater directly into streams by providing a buffer. Table 1 indicates the station
numbers that buffers between the stormwater discharge and the stream have been
incorporated.

As mentioned in the permit application to the Department of the Army, the
NCDOT has designed the stream relocations using natural stream techniques that
includes a mimic of slope, riffle slope, pool slope, etc. to resemble the existing stream
conditions as detailed by the NCWRC, item #5 and by the USFWS, item #3 on page 3. A
copy of stream data from the reference reach and proposed reach was included with
permit drawings of the original Section 404 permit application. The NCDOT is also
providing a copy to Mr. Micky Clemmons of the NCWRC.
The NCDOT has considered the comment for the USFWS regarding riparian
vegetation, Item #1 on page 3. The NCDOT will revegetate stream relocation areas with
similar species. A typical of the revegetation plan is attached to this letter, and this
typical also includes the species to be planted.
On page 3, item #2, the USFWS expressed a desire to inspect stream segments
prior to water diversion. The NCDOT has committed to constructing relocated channels
as depicted on the attached permit drawings that constitutes appropriate review prior to
construction. The NCDOT will make an effort to contact the USFWS to inspect the
stream relocated channel prior to water diversion. However, the NCDOT does not
believe it reasonable nor practicable to cease work on the project until the USFWS
inspects completed work. If a representative desires to the review the stream relocation,
the representative should contact the NCDOT Resident Engineer for the project to
arrange for a site visit.
The USFWS suggests that the NCDOT monitor channel construction for five (5)
years and submit annual reports to the resource agencies. The NCDOT believes that two
(2) years of monitoring is sufficient. The NCDOT bases this belief that it is highly likely
that "stream forming" storm events will occur within this two-year period.
As noted in the letter transmitting comments from the public notice, all of the
responding agencies recommended that no Department of the Army permit be issued
until a mitigation banking agreement is developed for the Tulula Creek Mitigation Bank.
The NCDOT initiated an umbrella Mitigation Banking Instrument (MBI) during the
summer of 1999 to establish the framework for all NCDOT mitigation sites. Since this
submission, the USACE has requested that the NCDOT pursue a site specific MBI for
Tulula and other mitigation sites. The NCDOT has been developing a draft site specific
Response to Comments on Public Notice Page 3 of 5
TIP No. A-9 DD March 27, 2000
MBI for the Tulula site. In November 1999, the USACE suggested that an MBI may not
be appropriate for the Tulula site. A decision has not been made whether this site will be
established as a bank.
If the Tulula site is not used as a bank, the NCDOT believes that the site will
provide sufficient mitigation for both wetland and stream impacts. The NCDOT has
begun construction of the mitigation site, and plans to complete construction during the
summer of 2001. The NCDOT has not initiated a search in the drainages suggested by
the USFWS because it believes that the Tulula site provides sufficient mitigation for
project related impacts. The NCDOT appreciates the USFWS's suggestion that the
NCDOT investigate mitigation opportunities in these two drainages and will consider this
suggestion in its mitigation search for the future sections of TIP No. A-9.
The NCDOT agrees with the USFWS's determination that the recent discovery of
the Indiana bat (Myotis sodalis) in western North Carolina necessitates greater evidence
to support the biological conclusion of "No effect" for the species (USFWS, page 4) that
was included in the Reevaluation of the Final EIS for TIP No. A-91). The NCDOT
submitted the Section 404 permit application prior to this species' discovery during the
summer of 1999. The NCDOT is working to resolve this issue and tentatively plans to
conduct surveys for the bat during the spring/ summer of 2000. The NCDOT will
provide a copy of the survey results and subsequent biological conclusion to the USFWS
and USACE.
Modification of 401 Water Quality Certification (WQC) is also necessary due to
the changes in impacts to wetlands and streams described earlier in this letter. The
NCDOT requests that the N. C. Division of Water Quality modify the existing 401 WQC
to include these changes. A check for this modification has been attached.
In summary with regard to project impacts to waters of the United States,
construction of TIP No. A-9 DD will result in the fill of 6.86 acres of wetlands, in
excavation of 1.14 acres of wetlands, mechanized clearing of 0.62 acres of wetlands and
0.02 acre of drained wetlands. The project will impact 3.77 acres of surface water and
5,621 feet of stream. Of this amount, 4,014 feet of stream will be relocated using natural
stream channel design techniques in the hydraulic planning. There will be 1,607 feet of
stream loss from project construction.

Subject: Graham County, NC 28 (Future US 19-74-129 Relocation), from Edwards
Gap to east of SR 1231 at Stecoah, Federal Aid Project
No. APD-12-1(22), State Project No. 8.3 019122, TIP No. A-9 DD;
USACE Action Id 199930861; WQC Project # 990414; USFWS
Log # 4-2-96-022.
Dear Sir:
As you are aware, the North Carolina Department of Transportation submitted a
Section 404 Individual Permit (IP) application in a letter dated April 20, 1999. The
proposed action involves widening and realigning NC 28 in Graham County, from
Edwards Gap to east of SR 1231 at Stecoah. The U. S. Army Corps of Engineers
(USACE) placed the proposed action by NCDOT on public notice September 16, 1999
(USACE Action Id 199930861). In a letter dated October 29, 1999, the USACE
forwarded comments from resource agencies, particularly those from the U. S.
Environmental Protection Agency (EPA), N. C. Wildlife Resources Commission
(NCWRC) and U. S. Fish and Wildlife Service (USFWS), and asked for the NCDOT's
response to these comments.
Response to Comments from EPA
Specifically, the USACE asked that the NCDOT respond directly to EPA in
regard to its concerns with the subject action. The NCDOT met with the EPA on site to
discuss and review the project. A response to EPA's comments was provided in a letter
dated December 23, 1999.
t a ,

Changes in Impacts to waters of the United States
A copy of revised permit drawings is attached to this letter. As the NCDOT has
finalized roadway design plans for the project, impacts to waters of the United States
have changed at four sites; Site 5, 7, 10 and 11. Site 11 involves a reduction in the
wetland impact from 1.48 acres in the permit application to 1.43 acres, a reduction of
0.05 acre.
Revisions at Site 5, 7 and 10 are associated with stream impacts. At Site 5, the
amount of existing channel impact remains 869 feet, although the amount of relocated
channel has decreased from 741 feet to 715 feet. The channel loss at this site is now 154
feet.
At Site 7 and 10, the amount of existing channel impacted has increased. At Site
7, the impact has increased from 66 feet to 148 feet. It was noted that Table 2 of the
permit application listed this impact as relocation only when in fact it should have been
channel loss and relocation. There will be 33 feet of channel relocation at this site. The
channel loss at this site is 133 feet.
At Site 10, the impact to existing channel has increased from 144 feet to 213 feet.
Therefore, the channel loss associated with this site is now 213 feet.
Response to Comments from Resource Agencies
The NCDOT has reviewed the comments provided by the resource agencies. The
NCDOT believes that it can comply with comments from the NCWRC as special
conditions, although comment #9 needs to be modified. The NCDOT suggests that this
comment be modified to state "Stormwater should be directed to buffer areas or retention
basins, as much as possible and practicable, to avoid routing it directly into streams".
The NCDOT has investigated this concern of the NCWRC, an issue that was also
raised by the USFWS on page 2 of its comments. The NCDOT has taken the following
measures in response to comment #9 from the NCWRC and USFWS to avoid routing
stormwater directly into streams by providing a buffer. Table 1 indicates the station
numbers that buffers between the stormwater discharge and the stream have been
incorporated.

As mentioned in the permit application to the Department of the Army, the
NCDOT has designed the stream relocations using natural stream techniques that
includes a mimic of slope, riffle slope, pool slope, etc. to resemble the existing stream
conditions as detailed by the NCWRC, item #5 and by the USFWS, item #3 on page 3. A
copy of stream data from the reference reach and proposed reach was included with
permit drawings of the original Section 404 permit application. The NCDOT is also
providing a copy to Mr. Micky Clemmons of the NCWRC.
The NCDOT has considered the comment for the USFWS regarding riparian
vegetation, Item #1 on page 3. The NCDOT will revegetate stream relocation areas with
similar species. A typical of the revegetation plan is attached to this letter, and this
typical also includes the species to be planted.
On page 3, item #2, the USFWS expressed a desire to inspect stream segments
prior to water diversion. The NCDOT has committed to constructing relocated channels
as depicted on the attached permit drawings that constitutes appropriate review prior to
construction. The NCDOT will make an effort to contact the USFWS to inspect the
stream relocated channel prior to water diversion. However, the NCDOT does not
believe it reasonable nor practicable to cease work on the project until the USFWS
inspects completed work. If a representative desires to the review the stream relocation,
the representative should contact the NCDOT Resident Engineer for the project to
arrange for a site visit.
The USFWS suggests that the NCDOT monitor channel construction for five (5)
years and submit annual reports to the resource agencies. The NCDOT believes that two
(2) years of monitoring is sufficient. The NCDOT bases this belief that it is highly likely
that "stream forming" storm events will occur within this two-year period.
As noted in the letter transmitting comments from the public notice, all of the
responding agencies recommended that no Department of the Army permit be issued
until a mitigation banking agreement is developed for the Tulula Creek Mitigation Bank.
The NCDOT initiated an umbrella Mitigation Banking Instrument (MBI) during the
summer of 1999 to establish the framework for all NCDOT mitigation sites. Since this
submission, the USACE has requested that the NCDOT pursue a site specific MBI for
Tulula and other mitigation sites. The NCDOT has been developing a draft site specific
Response to Comments on Public Notice
TIP No. A-9 DD
Page 3 of 5
March 27, 2000

MBI for the Tulula site. In November 1999, the USACE suggested that an MBI may not
be appropriate for the Tulula site. A decision has not been made whether this site will be
established as a bank.
If the Tulula site is not used as a bank, the NCDOT believes that the site will
provide sufficient mitigation for both wetland and stream impacts. The NCDOT has
begun construction of the mitigation site, and plans to complete construction during the
summer of 2001. The NCDOT has not initiated a search in the drainages suggested by
the USFWS because it believes that the Tulula site provides sufficient mitigation for
project related impacts. The NCDOT appreciates the USFWS's suggestion that the
NCDOT investigate mitigation opportunities in these two drainages and will consider this
suggestion in its mitigation search for the future sections of TIP No. A-9.
The NCDOT agrees with the USFWS's determination that the recent discovery of
the Indiana bat (Myotis sodalis) in western North Carolina necessitates greater evidence
to support the biological conclusion of "No effect" for the species (USFWS, page 4) that
was included in the Reevaluation of the Final EIS for TIP No. A-91). The NCDOT
submitted the Section 404 permit application prior to this species' discovery during the
summer of 1999. The NCDOT is working to resolve this issue and tentatively plans to
conduct surveys for the bat during the spring/ summer of 2000. The NCDOT will
provide a copy of the survey results and subsequent biological conclusion to the USFWS
and USACE.
Modification of 401 Water Quality Certification (WQC) is also necessary due to
the changes in impacts to wetlands and streams described earlier in this letter. The
NCDOT requests that the N. C. Division of Water Quality modify the existing 401 WQC
to include these changes. A check for this modification has been attached.
In summary with regard to project impacts to waters of the United States,
construction of TIP No. A-9 DD will result in the fill of 6.86 acres of wetlands, in
excavation of 1.14 acres of wetlands, mechanized clearing of 0.62 acres of wetlands and
0.02 acre of drained wetlands. The project will impact 3.77 acres of surface water and
5,621 feet of stream. Of this amount, 4,014 feet of stream will be relocated using natural
stream channel design techniques in the hydraulic planning. There will be 1,607 feet of
stream loss from project construction.

Subject: Graham County, NC 28 (Future US 19-74-129 Relocation), from Edwards
Gap to east of SR 1231 at Stecoah, Federal Aid Project
No. APD-12-1(22), State Project No. 8.3 019122, TIP No. A-9 DD;
USACE Action Id 199930861; WQC Project # 990414; USFWS
Log # 4-2-96-022.
Dear Sir:
As you are aware, the North Carolina Department of Transportation submitted a
Section 404 Individual Permit (IP) application in a letter dated April 20, 1999. The
proposed action involves widening and realigning NC 28 in Graham County, from
Edwards Gap to east of SR 1231 at Stecoah. The U. S. Army Corps of Engineers
(USACE) placed the proposed action by NCDOT on public notice September 16, 1999
(USACE Action Id 199930861). In a letter dated October 29, 1999, the USACE
forwarded comments from resource agencies, particularly those from the U. S.
Environmental Protection Agency (EPA), N. C. Wildlife Resources Commission
(NCWRC) and U. S. Fish and Wildlife Service (USFWS), and asked for the NCDOT's
response to these comments.
Response to Comments from EPA
Specifically, the USACE asked that the NCDOT respond directly to EPA in
regard to its concerns with the subject action. The NCDOT met with the EPA on site to
discuss and review the project. A response to EPA's comments was provided in a letter
dated December 23, 1999.

Changes in Impacts to waters of the United States
A copy of revised permit drawings is attached to this letter. As the NCDOT has
finalized roadway design plans for the project, impacts to waters of the United States
have changed at four sites; Site 5, 7, 10 and 11. Site 11 involves a reduction in the
wetland impact from 1.48 acres in the permit application to 1.43 acres, a reduction of
0.05 acre.
Revisions at Site 5, 7 and 10 are associated with stream impacts. At Site 5, the
amount of existing channel impact remains 869 feet, although the amount of relocated
channel has decreased from 741 feet to 715 feet. The channel loss at this site is now 154
feet.
At Site 7 and 10, the amount of existing channel impacted has increased. At Site
7, the impact has increased from 66 feet to 148 feet. It was noted that Table 2 of the
permit application listed this impact as relocation only when in fact it should have been
channel loss and relocation. There will be 33 feet of channel relocation at this site. The
channel loss at this site is 133 feet.
At Site 10, the impact to existing channel has increased from 144 feet to 213 feet.
Therefore, the channel loss associated with this site is now 213 feet.
Response to Comments from Resource Agencies
The NCDOT has reviewed the comments provided by the resource agencies. The
NCDOT believes that it can comply with comments from the NCWRC as special
conditions, although comment 99 needs to be modified. The NCDOT suggests that this
comment be modified to state "Stormwater should be directed to buffer areas or retention
basins, as much as possible and practicable, to avoid routing it directly into streams".
The NCDOT has investigated this concern of the NCWRC, an issue that was also
raised by the USFWS on page 2 of its comments. The NCDOT has taken the following
measures in response to comment #9 from the NCWRC and USFWS to avoid routing
stormwater directly into streams by providing a buffer. Table 1 indicates the station
numbers that buffers between the stormwater discharge and the stream have been
incorporated.

As mentioned in the permit application to the Department of the Army, the
NCDOT has designed the stream relocations using natural stream techniques that
includes a mimic of slope, riffle slope, pool slope, etc. to resemble the existing stream
conditions as detailed by the NCWRC, item #5 and by the USFWS, item #3 on page 3. A
copy of stream data from the reference reach and proposed reach was included with
permit drawings of the original Section 404 permit application. The NCDOT is also
providing a copy to Mr. Micky Clemmons of the NCWRC.
The NCDOT has considered the comment for the USFWS regarding riparian
vegetation, Item #1 on page 3. The NCDOT will revegetate stream relocation areas with
similar species. A typical of the revegetation plan is attached to this letter, and this
typical also includes the species to be planted.
On page 3, item #2, the USFWS expressed a desire to inspect stream segments
prior to water diversion. The NCDOT has committed to constructing relocated channels
as depicted on the attached permit drawings that constitutes appropriate review prior to
construction. The NCDOT will make an effort to contact the USFWS to inspect the
stream relocated channel prior to water diversion. However, the NCDOT does not
believe it reasonable nor practicable to cease work on the project until the USFWS
inspects completed work. If a representative desires to the review the stream relocation,
the representative should contact the NCDOT Resident Engineer for the project to
arrange for a site visit.
The USFWS suggests that the NCDOT monitor channel construction for five (5)
years and submit annual reports to the resource agencies. The NCDOT believes that two
(2) years of monitoring is sufficient. The NCDOT bases this belief that it is highly likely
that "stream forming" storm events will occur within this two-year period.
As noted in the letter transmitting comments from the public notice, all of the
responding agencies recommended that no Department of the Army permit be issued
until a mitigation banking agreement is developed for the Tulula Creek Mitigation Bank.
The NCDOT initiated an umbrella Mitigation Banking Instrument (MBI) during the
summer of 1999 to establish the framework for all NCDOT mitigation sites. Since this
submission, the USACE has requested that the NCDOT pursue a site specific MBI for
Tulula and other mitigation sites. The NCDOT has been developing a draft site specific
Response to Comments on Public Notice Page 3 of 5
TIP No. A-9 DD March 27, 2000
MBI for the Tulula site. In November 1999, the USACE suggested that an MBI may not
be appropriate for the Tulula site. A decision has not been made whether this site will be
established as a bank.
If the Tulula site is not used as a bank, the NCDOT believes that the site will
provide sufficient mitigation for both wetland and stream impacts. The NCDOT has
begun construction of the mitigation site, and plans to complete construction during the
summer of 2001. The NCDOT has not initiated a search in the drainages suggested by
the USFWS because it believes that the Tulula site provides sufficient mitigation for
project related impacts. The NCDOT appreciates the USFWS's suggestion that the
NCDOT investigate mitigation opportunities in these two drainages and will consider this
suggestion in its mitigation search for the future sections of TIP No. A-9.
The NCDOT agrees with the USFWS's determination that the recent discovery of
the Indiana bat (Myotis sodalis) in western North Carolina necessitates greater evidence
to support the biological conclusion of "No effect" for the species (USFWS, page 4) that
was included in the Reevaluation of the Final EIS for TIP No. A-91). The NCDOT
submitted the Section 404 permit application prior to this species' discovery during the
summer of 1999. The NCDOT is working to resolve this issue and tentatively plans to
conduct surveys for the bat during the spring/ summer of 2000. The NCDOT will
provide a copy of the survey results and subsequent biological conclusion to the USFWS
and USACE.
Modification of 401 Water Quality Certification (WQC) is also necessary due to
the changes in impacts to wetlands and streams described earlier in this letter. The
NCDOT requests that the N. C. Division of Water Quality modify the existing 401 WQC
to include these changes. A check for this modification has been attached.
In summary with regard to project impacts to waters of the United States,
construction of TIP No. A-9 DD will result in the fill of 6.86 acres of wetlands, in
excavation of 1.14 acres of wetlands, mechanized clearing of 0.62 acres of wetlands and
0.02 acre of drained wetlands. The project will impact 3.77 acres of surface water and
5,621 feet of stream. Of this amount, 4,014 feet of stream will be relocated using natural
stream channel design techniques in the hydraulic planning. There will be 1,607 feet of
stream loss from project construction.

Subject: Graham County, NC 28 (Future US 19-74-129 Relocation), from Edwards
Gap to east of SR 1231 at Stecoah, Federal Aid Project
No. APD-12-1(22), State Project No. 8.3 019122, TIP No. A-9 DD;
USACE Action Id 199930861; WQC Project # 990414; USFWS
Log # 4-2-96-022.
Dear Sir:
As you are aware, the North Carolina Department of Transportation submitted a
Section 404 Individual Permit (IP) application in a letter dated April 20, 1999. The
proposed action involves widening and realigning NC 28 in Graham County, from
Edwards Gap to east of SR 1231 at Stecoah. The U. S. Army Corps of Engineers
(USACE) placed the proposed action by NCDOT on public notice September 16, 1999
(USACE Action Id 199930861). In a letter dated October 29, 1999, the USACE
forwarded comments from resource agencies, particularly those from the U. S.
Environmental Protection Agency (EPA), N. C. Wildlife Resources Commission
(NCWRC) and U. S. Fish and Wildlife Service (USFWS), and asked for the NCDOT's
response to these comments.
Response to Comments from EPA
Specifically, the USACE asked that the NCDOT respond directly to EPA in
regard to its concerns with the subject action. The NCDOT met with the EPA on site to
discuss and review the project. A response to EPA's comments was provided in a letter
dated December 23, 1999.
Changes in Impacts to waters of the United States
A copy of revised permit drawings is attached to this letter. As the NCDOT has
finalized roadway design plans for the project, impacts to waters of the United States
have changed at four sites; Site 5, 7, 10 and 11. Site 11 involves a reduction in the
wetland impact from 1.48 acres in the permit application to 1.43 acres, a reduction of
0.05 acre.
Revisions at Site 5, 7 and 10 are associated with stream impacts. At Site 5, the
amount of existing channel impact remains 869 feet, although the amount of relocated
channel has decreased from 741 feet to 715 feet. The channel loss at this site is now 154
feet.
At Site 7 and 10, the amount of existing channel impacted has increased. At Site
7, the impact has increased from 66 feet to 148 feet. It was noted that Table 2 of the
permit application listed this impact as relocation only when in fact it should have been
channel loss and relocation. There will be 33 feet of channel relocation at this site. The
channel loss at this site is 133 feet.
At Site 10, the impact to existing channel has increased from 144 feet to 213 feet.
Therefore, the channel loss associated with this site is now 213 feet.
Response to Comments from Resource Agencies
The NCDOT has reviewed the comments provided by the resource agencies. The
NCDOT believes that it can comply with comments from the NCWRC as special
conditions, although comment #9 needs to be modified. The NCDOT suggests that this
comment be modified to state "Stormwater should be directed to buffer areas or retention
basins, as much as possible and practicable, to avoid routing it directly into streams".
The NCDOT has investigated this concern of the NCWRC, an issue that was also
raised by the USFWS on page 2 of its comments. The NCDOT has taken the following
measures in response to comment #9 from the NCWRC and USFWS to avoid routing
stormwater directly into streams by providing a buffer. Table 1 indicates the station
numbers that buffers between the stormwater discharge and the stream have been
incorporated.

As mentioned in the permit application to the Department of the Army, the
NCDOT has designed the stream relocations using natural stream techniques that
includes a mimic of slope, riffle slope, pool slope, etc. to resemble the existing stream
conditions as detailed by the NCWRC, item #5 and by the USFWS, item #3 on page 3. A
copy of stream data from the reference reach and proposed reach was included with
permit drawings of the original Section 404 permit application. The NCDOT is also
providing a copy to Mr. Micky Clemmons of the NCWRC.
The NCDOT has considered the comment for the USFWS regarding riparian
vegetation, Item #1 on page 3. The NCDOT will revegetate stream relocation areas with
similar species. A typical of the revegetation plan is attached to this letter, and this
typical also includes the species to be planted.
On page 3, item #2, the USFWS expressed a desire to inspect stream segments
prior to water diversion. The NCDOT has committed to constructing relocated channels
as depicted on the attached permit drawings that constitutes appropriate review prior to
construction. The NCDOT will make an effort to contact the USFWS to inspect the
stream relocated channel prior to water diversion. However, the NCDOT does not
believe it reasonable nor practicable to cease work on the project until the USFWS
inspects completed work. If a representative desires to the review the stream relocation,
the representative should contact the NCDOT Resident Engineer for the project to
arrange for a site visit.
The USFWS suggests that the NCDOT monitor channel construction for five (5)
years and submit annual reports to the resource agencies. The NCDOT believes that two
(2) years of monitoring is sufficient. The NCDOT bases this belief that it is highly likely
that "stream forming" storm events will occur within this two-year period.
As noted in the letter transmitting comments from the public notice, all of the
responding agencies recommended that no Department of the Army permit be issued
until a mitigation banking agreement is developed for the Tulula Creek Mitigation Bank.
The NCDOT initiated an umbrella Mitigation Banking Instrument (MBI) during the
summer of 1999 to establish the framework for all NCDOT mitigation sites. Since this
submission, the USACE has requested that the NCDOT pursue a site specific MBI for
Tulula and other mitigation sites. The NCDOT has been developing a draft site specific
Response to Comments on Public Notice Page 3 of 5
TIP No. A-9 DD March 27, 2000
MBI for the Tulula site. In November 1999, the USACE suggested that an MBI may not
be appropriate for the Tulula site. A decision has not been made whether this site will be
established as a bank.
If the Tulula site is not used as a bank, the NCDOT believes that the site will
provide sufficient mitigation for both wetland and stream impacts. The NCDOT has
begun construction of the mitigation site, and plans to complete construction during the
summer of 2001. The NCDOT has not initiated a search in the drainages suggested by
the USFWS because it believes that the Tulula site provides sufficient mitigation for
project related impacts. The NCDOT appreciates the USFWS's suggestion that the
NCDOT investigate mitigation opportunities in these two drainages and will consider this
suggestion in its mitigation search for the future sections of TIP No. A-9.
The NCDOT agrees with the USFWS's determination that the recent discovery of
the Indiana bat (Myotis sodalis) in western North Carolina necessitates greater evidence
to support the biological conclusion of "No effect" for the species (USFWS, page 4) that
was included in the Reevaluation of the Final EIS for TIP No. A-913. The NCDOT
submitted the Section 404 permit application prior to this species' discovery during the
summer of 1999. The NCDOT is working to resolve this issue and tentatively plans to
conduct surveys for the bat during the spring/ summer of 2000. The NCDOT will
provide a copy of the survey results and subsequent biological conclusion to the USFWS
and USACE.
Modification of 401 Water Quality Certification (WQC) is also necessary due to
the changes in impacts to wetlands and streams described earlier in this letter. The
NCDOT requests that the N. C. Division of Water Quality modify the existing 401 WQC
to include these changes. A check for this modification has been attached.
In summary with regard to project impacts to waters of the United States,
construction of TIP No. A-9 DD will result in the fill of 6.86 acres of wetlands, in
excavation of 1.14 acres of wetlands, mechanized clearing of 0.62 acres of wetlands and
0.02 acre of drained wetlands. The project will impact 3.77 acres of surface water and
5,621 feet of stream. Of this amount, 4,014 feet of stream will be relocated using natural
stream channel design techniques in the hydraulic planning. There will be 1,607 feet of
stream loss from project construction.

Subject: Graham County, NC 28 (Future US 19-74-129 Relocation), from Edwards
Gap to east of SR 1231 at Stecoah, Federal Aid Project
No. APD-12-1(22), State Project No. 8.3 019122, TIP No. A-9 DD;
USACE Action Id 199930861; WQC Project # 990414; USFWS
Log # 4-2-96-022.
Dear Sir:
As you are aware, the North Carolina Department of Transportation submitted a
Section 404 Individual Permit (IP) application in a letter dated April 20, 1999. The
proposed action involves widening and realigning NC 28 in Graham County, from
Edwards Gap to east of SR 1231 at Stecoah. The U. S. Army Corps of Engineers
(USACE) placed the proposed action by NCDOT on public notice September 16, 1999
(USACE Action Id 199930861). In a letter dated October 29, 1999, the USACE
forwarded comments from resource agencies, particularly those from the U. S.
Environmental Protection Agency (EPA), N. C. Wildlife Resources Commission
(NCWRC) and U. S. Fish and Wildlife Service (USFWS), and asked for the NCDOT's
response to these comments.
Response to Comments from EPA
Specifically, the USACE asked that the NCDOT respond directly to EPA in
regard to its concerns with the subject action. The NCDOT met with the EPA on site to
discuss and review the project. A response to EPA's comments was provided in a letter
dated December 23, 1999.

Changes in Impacts to waters of the United States
A copy of revised permit drawings is attached to this letter. As the NCDOT has
finalized roadway design plans for the project, impacts to waters of the United States
have changed at four sites; Site 5, 7, 10 and 11. Site 11 involves a reduction in the
wetland impact from 1.48 acres in the permit application to 1.43 acres, a reduction of
0.05 acre.
Revisions at Site 5, 7 and 10 are associated with stream impacts. At Site 5, the
amount of existing channel impact remains 869 feet, although the amount of relocated
channel has decreased from 741 feet to 715 feet. The channel loss at this site is now 154
feet.
At Site T and 10, the amount of existing channel impacted has increased. At Site
7, the impact has increased from 66 feet to 148 feet. It was noted that Table 2 of the
permit application listed this impact as relocation only when in fact it should have been
channel loss and relocation. There will be 33 feet of channel relocation at this site. The
channel loss at this site is 133 feet.
At Site 10, the impact to existing channel has increased from 144 feet to 213 feet.
Therefore, the channel loss associated with this site is now 213 feet.
Response to Comments from Resource Agencies
The NCDOT has reviewed the comments provided by the resource agencies. The
NCDOT believes that it can comply with comments from the NCWRC as special
conditions, although comment #9 needs to be modified. The NCDOT suggests that this
comment be modified to state "Stormwater should be directed to buffer areas or retention
basins, as much as possible and practicable, to avoid routing it directly into streams".
The NCDOT has investigated this concern of the NCWRC, an issue that was also
raised by the USFWS on page 2 of its comments. The NCDOT has taken the following
measures in response to comment #9 from the NCWRC and USFWS to avoid routing
stormwater directly into streams by providing a buffer. Table 1 indicates the station
numbers that buffers between the stormwater discharge and the stream have been

As mentioned in the permit application to the Department of the Army, the
NCDOT has designed the stream relocations using natural stream techniques that
includes a mimic of slope, riffle slope, pool slope, etc. to resemble the existing stream
conditions as detailed by the NCWRC, item #5 and by the USFWS, item #3 on page 3. A
copy of stream data from the reference reach and proposed reach was included with
permit drawings of the original Section 404 permit application. The NCDOT is also
providing a copy to Mr. Micky Clemmons of the NCWRC.
The NCDOT has considered the comment for the USFWS regarding riparian
vegetation, Item #1 on page 3. The NCDOT will revegetate stream relocation areas with
similar species. A typical of the revegetation plan is attached to this letter, and this
typical also includes the species to be planted.
On page 3, item #2, the USFWS expressed a desire to inspect stream segments
prior to water diversion. The NCDOT has committed to constructing relocated channels
as depicted on the attached permit drawings that constitutes appropriate review prior to
construction. The NCDOT will make an effort to contact the USFWS to inspect the
stream relocated channel prior to water diversion. However, the NCDOT does not
believe it reasonable nor practicable to cease work on the project until the USFWS
inspects completed work. If a representative desires to the review the stream relocation,
the representative should contact the NCDOT Resident Engineer for the project to
arrange for a site visit.
The USFWS suggests that the NCDOT monitor channel construction for five (5)
years and submit annual reports to the resource agencies. The NCDOT believes that two
(2) years of monitoring is sufficient. The NCDOT bases this belief that it is highly likely
that "stream forming" storm events will occur within this two-year period.
As noted in the letter transmitting comments from the public notice, all of the
responding agencies recommended that no Department of the Army permit be issued
until a mitigation banking agreement is developed for the Tulula Creek Mitigation Bank.
The NCDOT initiated an umbrella Mitigation Banking Instrument (MBI) during the
summer of 1999 to establish the framework for all NCDOT mitigation sites. Since this
submission, the USACE has requested that the NCDOT pursue a site specific MBI for
Tulula and other mitigation sites. The NCDOT has been developing a draft site specific

r
MBI for the Tulula site. In November 1999, the USACE suggested that an MBI may not
be appropriate for the Tulula site. A decision has not been made whether this site will be
established as a bank.
If the Tulula site is not used as a bank, the NCDOT believes that the site will
provide sufficient mitigation for both wetland and stream impacts. The NCDOT has
begun construction of the mitigation site, and plans to complete construction during the
summer of 2001. The NCDOT has not initiated a search in the drainages suggested by
the USFWS because it believes that the Tulula site provides sufficient mitigation for
project related impacts. The NCDOT appreciates the USFWS's suggestion that the
NCDOT investigate mitigation opportunities in these two drainages and will consider this
suggestion in its mitigation search for the future sections of TIP No. A-9.
The NCDOT agrees with the USFWS's determination that the recent discovery of
the Indiana bat (Myotis sodalis) in western North Carolina necessitates greater evidence
to support the biological conclusion of "No effect" for the species (USFWS, page 4) that
was included in the Reevaluation of the Final EIS for TIP No. A-91). The NCDOT
submitted the Section 404 permit application prior to this species' discovery during the
summer of 1999. The NCDOT is working to resolve this issue and tentatively plans to
conduct surveys for the bat during the spring/ summer of 2000. The NCDOT will
provide a copy of the survey results and subsequent biological conclusion to the USFWS
and USACE.
Modification of 401 Water Quality Certification (WQC) is also necessary due to
the changes in impacts to wetlands and streams described earlier in this letter. The
NCDOT requests that the N. C. Division of Water Quality modify the existing 401 WQC
to include these changes. A check for this modification has been attached.
In summary with regard to project impacts to waters of the United States,
construction of TIP No. A-9 DD will result in the fill of 6.86 acres of wetlands, in
excavation of 1.14 acres of wetlands, mechanized clearing of 0.62 acres of wetlands and
0.02 acre of drained wetlands. The project will impact 3.77 acres of surface water and
5,621 feet of stream. Of this amount, 4,014 feet of stream will be relocated using natural
stream channel design techniques in the hydraulic planning. There will be 1,607 feet of
stream loss from project construction.
