Subject: Action ID No. 199304806, TIP R-2562, Widen NC 87 to a four-lane divided highway
with a 46 foot wide median from I-95 in Cumberland County to NC 20 in Bladen County, North
Carolina, TIP No. R-2562AA/AB, State Project No. 6.439001T.

Mr. William D. Gilmore, P.E., Manager
Project Development & Environmental Analysis
1548 Mail Service Center
Raleigh, N.C. 27699-1548
Dear Mr. Gilmore:
Reference the Department of the Army permit issued on March 7, 2000 for the subject
project and your letter dated September 14, 2000 requesting a permit modification regarding
final permit drawings, revised wetland and stream impacts, a revised cornpensatory mitigation
proposal and wetland mitigation debit ledger map, and a temporary workbridge at Rockfish
Creek for the subject project.
The referenced DA permit authorized the discharge of fill material into 13.508 acres of
wetlands and 1,457 feet of stream associated with the Cape Fear River and its tributaries, to
construct a four-lane divided highway with a 46 foot wide median from I-95 in Cumberland
County to NC 20 in Bladen County, North Carolina (TIP Project R-2562AA/AB). These impacts
include approximately 8.2 acres to non-riverine wetlands and 5.3 acres to riverine wetlands.
The subject permit was issued based on preliminary permit drawings with the condition
that final permit drawings would be provided following completion of the final design plans.
Final permit drawings for the subject project were required by North Carolina Division of Water
Quality, Certification Number 3268, dated February 22, 2000. Your letter of September 14,
2000, provides the required final permit drawings and associated revised wetland and stream
impacts.
The total wetland impacts of TIP Project R-2562AA/AB have been decreased from 13.508
acres to 11.154 acres. These revised impacts include 2.891 acres to riverine wetlands and 8.263
acres to non-riverine wetlands. As stated in your letter, these impacts have been revised due to
re-calculations of areas of authorized discharged fill, excavation, clearing (temporary and
permanent impacts), and drainage impacts. Reductions in wetland impacts are largely due to the
elimination of an approved stream relocation at Wetland Site 10 of Section AA. This stream
relocation, as approved, is located within jurisdictional wetlands and causes a permanent wetland
drainage loss of 1.66 acres. In addition, wetland impacts at this site were further reduced due to
reduced areas of fill, excavation, and permanent clearing. As a result wetland impacts at this
site were reduced from 2.37 to 0.245 acres.
Based on your letter dated September 14, 2000, the total stream impacts have increased
from 1,457 to 1,470 feet. As stated in your letter, the total stream impacts for this project were
incorrectly totaled as 1,457 feet due to an omission 13 feet of stream impacts at Site 9 in Section
AA. The total stream impacts for this project should be corrected to be 1,470 feet. In addition,
elimination of the approved 164 feet of relocated stream, located at Site 10 in Section AA, has
reduced wetland impacts, as described above, but it also decreases your proposed total onsite
stream relocation and increases the total proposed stream losses along this project. As a result,
the total onsite stream relocation located in Section AA has decreased from 640 feet to 476 feet
and the permanent stream losses resulting from the entire project, Sections AA and AB, have
increased from 830 feet (including the 13 feet of stream impact in Section AA described above)
to 994 feet. The revised total of offsite compensatory stream mitigation required to offset the
proposed stream losses (994 feet) is 1,988 feet.
Subsequent to issuance of the subject permit, the NCDOT determined that a temporary
workbridge is needed to provide construction access for the bridge improvements over Rockfish
Creek. The proposed temporary workbridge over Rockfish Creek will be constructed using the
top-down construction method and will be located between the new and the existing bridge, as
shown on permit drawing sheet numbers 12A and 12B, 24 dated July 25, 2000. This workbridge
will be removed following completion of both permanent bridges and will not result in any
permanent wetland impacts.
Special condition (10) of the Department of the Army permit dated March 7, 2000 requires
restoration of 16.4 acres of non-riverine and 10.6 acres of riverine wetland as described in the
approved mitigation plan for the Dowd Dairy Farms Mitigation Site dated May 1997. This
compensatory mitigation is required to offset the permanent impacts to approximately 8.2 acres
to non-riverine wetlands and 5.3 acres to riverine wetlands. Your request for a permit
modification proposes to similarly restore 16.4 acres of non-riverine and 5.8 acres of riverine
wetland at the Dowd Dairy Farms Mitigation Site. This compensatory mitigation is required to
offset the revised permanent impacts to approximately 2.8 acres (reduced from 5.3 acres) to
riverine wetlands, as described above and in your letter of September 14, 2000.
Special condition (11 a) of the Department of the Army permit dated March 7, 2000
requires onsite mitigation for 640 feet of the total 1,457 feet of unavoidable impacts to perennial
stream channel associated with this project by relocating 640 feet of perennial stream, within the
existing ROW and adjacent to the project. Your request for a permit modification proposes to
provide similar onsite mitigation for 476 feet of the total 1,470 feet of unavoidable impacts to
perennial stream channel associated with this project, in accordance with the attached plans at
the following sites:

AA 15 99+31L 89
Special condition (1 lb) of the Department of the Army permit dated March 7, 2000
requires offsite mitigation for 830 feet of the total 1,457 feet of unavoidable impacts to perennial
stream channel associated with this project by payment to the North Carolina Wetlands
Restoration program (NCWRP) in an amount determined by NCWRP, sufficient to perform
1,660 feet of warm stream restoration located in Cataloging Unit 0303004 of the Cape Fear River
Basin. By letter dated June 12, 2000 the NCWRP received the required payment from the
NCDOT for the restoration of 1,660 feet of warm water stream. Your request for a permit
modification proposes to provide similar offsite mitigation for 994 feet of the total 1,470 feet of
unavoidable impacts to perennial stream channel associated with this project. The revised total
offsite mitigation is 1,988 feet. Since the NCDOT has made payment for 1,660 feet of offsite
stream mitigation, the remaining offsite stream mitigation to meet our requirements is 328 feet.
By letter dated October 6, 2000, the NCWRF stated it would accept payment for stream impacts
associated with the subject project and will provide up to 328 feet of stream restoration for
impacts associated with the subject project in Cataloging Unit 03030004 of the Cape Fear River
Basin.
You have requested a permit modification to authorize replacement of the permit drawings
with revised drawings that were attached to your letter dated September 14, 2000 that reflect the
proposed permit modifications described above. The revised drawings are attached and listed
below:

Project No. 6.439001T, TIP No. R-2562AA/AB; USACE Action
ID 199304806; DQC Project No. 990340.
Dear Sir:
The NC Department of Transportation (NCDOT) is widening and improving NC
87 from its existing two-lane section to a four-lane divided section with a 46-ft (14 m)
wide grass median. The 28 mi (45 km) long project begins east of I-95 in Cumberland
County and ends at the NC 87/Elizabethtown Bypass in Bladen County. Environmental
agencies authorized NCDOT to construct the AA and AB sections of R-2562 by a CWA
§404 IP (Permit No. 199304806) from the USACE and a CWA §401 Water Quality
Certification No. 3268 (Project No. 990340) from the NCDWQ. The permit and water
quality certification authorized NCDOT to drain, excavate, clear, or discharge fill
material into 13.508 ac (5.466 ha) of jurisdictional wetlands. The project's permits also
authorize NCDOT to discharge fill into 1,467 linear ft (447 m) of jurisdictional stream
associated with the Cape Fear River and its tributaries.
The project's CWA §§404/401 permits authorize NC Wetlands Restoration
Program (NCWRP) to provide compensatory off-site stream mitigation for 1,660 linear ft
(506 m) in Cataloging Unit 0303004 of the Cape Fear River Basin. Per a letter dated
June 12, 2000, NCWRP received check number 1016493 from NCDOT in the amount of
$207,500 as payment for the compensatory off-site stream mitigation requirements
authorized under the project's CWA permits. The purpose of this letter is to request that
NCWRP provide confirmation that you are willing to accept payment for additional
compensatory off-site stream mitigation requirements of R-2562AA/AB.

The NCDOT lost 164 linear ft (50 m) of permitted on-site stream mitigation at
Site 10 of the project's AA section. Therefore, NCDOT proposes to compensate for the
lost on-site stream mitigation through an additional 328 linear ft (100 m) off-site stream
mitigation at a 2:1 ratio.
The jurisdictional stream at Site 10 is a second order, unnamed, perennial
headwater stream associated with Murphy Swamp. The unnamed stream ultimately
drains into the Cape Fear River, and is located in Hydrologic Cataloging Unit 03030005
of the Cape Fear River Basin. This reach of the Cape Fear River and its associated
tributaries (Index Number 18-(26), 04/01/1959) fall under the NCDWQ best usage
classification of C. Please see enclosed Table D for a description of the impacted and
relocated jurisdictional streams along R-2562AA/AB. In order to assist in locating the
unnamed stream along Site 10 of the project's AA section, a project vicinity map drawn
onto the Cedar Creek USGS 7.5-minute series quadrangle map is also included as an
attachment. The map and table are part of the R-2562AA/AB Individual Permit
modification application letter dated September 14, 2000.
Off-site compensatory stream mitigation in Hydrologic Cataloging Unit 03030005
falls outside the hydrologic river basins that NCWRP covers for stream mitigation.
However, R-2562AA/AB was listed as one of NCDOT's original top 20 priority highway
projects that NCWRP agreed to help provide stream mitigation. At a 2:1 ratio, NCDOT
requests an additional 328 linear ft (100 m) of compensatory off-site stream mitigation
from NCWRP in order to compensate for the project's loss of on-site stream mitigation.
The additional 328 linear ft of off-site stream mitigation plus the permitted 1,660 ft of
off-site stream mitigation already provided by NCWRP comprise the project's revised
off-site stream mitigation total of 1,988 linear ft (606 m) now required for R-
2562AA/AB. At a cost of $125 per stream mitigation unit, NCDOT proposes to pay
NCWRP an additional $41,000 for compensatory stream mitigation upon receipt of a
modification to the project's CWA §401 Water Quality Certification.
Please send a confirmation letter to Mr. John Hennessy, DENR Division of Water
Quality-401 Wetlands, 1621 Mail Service Center, Raleigh, NC 27699-1621 and Mr. Dave
Timpy, NCDOT Coordinator, US Army Corps of Engineers, Wilmington Regulatory
Field Office, P.O. Box 1890, Wilmington, NC 28402-1890.

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 certification authorizes the NCDOT to impact a total of
11.154 acres of jurisdictional wetlands as follows: 1) place fill material in 6.444 acres of jurisdictional
wetlands, 2) excavate 0.956 acres of jurisdictional wetlands, 3) drain (through ditching) 3.534 acres of
jurisdictional wetlands, 4) permanently clear 0.220 acres of jurisdictional wetlands, and 5) temporarily clear
0.743 acres of jurisdictional wetlands. Moreover, this certification authorizes the placement of fill in 1470
linear feet of streams. The purpose of the project is to construct improvements to NC 87 from I-95 to NC
20. The project shall be constructed pursuant to the request for modification dated September 14, 2000.
Mitigation for the aforementioned impacts will be provided as described in Conditions 5 and 6 of this
certification. This 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
February 22, 2000 and all other corresponding modifications still apply.
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 with 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. Compensatory mitigation shall be done for 11.154 acres of wetlands (2.891acres of riverine
impacts and 8.263 acres of non-riverine wetland impacts). Therefore, using a replacement ratio
of 2:1, a total of 22.2 acres of wetland mitigation will be performed for this project. Mitigation
for these impacts will be provided for at the Dowd Dairy Farm Mitigation Site as follows: 1) 5.8
acres of riverine wetlands, 2) 16.4 acres of non-riverine wetlands.
Mitigation for impacts to the 1470 linear feet of streams will be provided through 470 linear feet
of on-site, and 1988 linear feet of off-site mitigation. We understand that you have chosen to
perform mitigation for the off-site portion through an in lieu payment to the North Carolina
Wetland Restoration Program (NCWRP), and that the WRP has agreed to implement mitigation
for the project. In accordance with 15A NCAC 2R.0500, the contribution will satisfy our
compensatory mitigation requirements under 15A NCAC 2H.0506(h). Until the Wetland
Restoration Program receives and clears your check (made payable to DENR - Wetland
Restoration Program), wetland or stream fill shall not occur. Mr. Ron Ferrell should be contacted
at 919-733-5083 ext. 358 if you have any questions concerning the Wetland Restoration Program.
The payment to NCWRP shall be sent within two months of issuance of the 404 permit.
7. Upon completion of the project, the NCDOT shall complete and return the enclosed "Certification
of Completion Form" to notify DWQ when all work included in the 401 Certification has been
completed. The responsible parry shall complete the attached form and return it to the
401/Wetlands Unit of the Division of Water Quality upon completion of the project.
8. 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

Dear Sir:
This North Carolina Department of Transportation (NCDOT) anplication nronoses to
modify the March 7, 2000 Clean Water Act (CWA)&404 IP and February 22, 2000
CWA $401 Water Oualitv Certification for TIP No. R-2562AA/AB (NC 87). The entire
R-2562 project consists of widening and improving NC 87 from its existing two-lane
section to a four-lane divided section with a 46-ft (14-m) wide grass median. The 28 mi
(45 km) long project begins east of I-95 in Cumberland County and ends at the
NC 87/Elizabethtown Bypass in Bladen County.
Project Breakdown and Construction Schedule
For construction purposes, NCDOT divides the R-2562 project into five sections: AA,
AB, B, C, and D. The NCDOT completed construction on the B section of R-2562 in
December 1999. The project impacted 0.30 ac (0.12 ha) of wetlands and was authorized
under CWA §404 Nationwide Permit No. 26 (US Army Corps of Engineers Action ID
199704613, NC Division of Water Quality Project No. 97101). The NCDOT began
constructing the AA and AB sections of the project in April 2000. The Project
Breakdown Map for R-2562, located at the end of this permit application modification
letter, illustrates each section of the project. Table 1 contains information concerning the
construction schedule, length, and termini of each section.

Project History for R-2562AA/AB
On April 14, 1999, NCDOT-submitted a CWA §404 permit application to the US Army
Corps of Engineers (USACE) for an Individual Permit (IP) and the NC Division of Water
Quality (NCDWQ) for a CWA §401 Water Quality Certification. The April 14, 1999
permit application was placed on Public Notice on June 3, 1999. In a letter dated August
13, 1999, NCDWQ placed the April 14, 1999 permit application on hold. On February
17, 2000, NCDOT submitted a.revised IP application that updated the initial April 1999
permit application. The NCDOT was authorized to construct the AA and AB sections of
R-2562 by a CWA §404 IP (Permit No. 199304806) from the USACE and a CWA §401
Water Quality Certification No. 3268 (Project No. 990340) from the NCDWQ. The
permit and water quality certification authorized NCDOT to drain, excavate, clear, or
discharge fill material into 13.508 ac (5.466 ha) of jurisdictional wetlands. The project's
permits also authorize NCDOT to discharge fill into 1,467 linear ft (447 m) of
jurisdictional stream associated with the Cape Fear River and its tributaries.
Environmental Agency Field Review
In order to complete the project's final wetland/stream design files and resolve the
project's drainage impacts, NCDOT natural system specialists Mr. Tim Bassette, Mr.
Jared Gray, and Mr. Chris Murray conducted a wetland delineation and drainage impact
field review along several sites of R-2562AA. The project's biological fieldwork was
completed March 13-15, 2000. On March 29, 2000, Mr. Bassette held an environmental
field review with Mr. Dave Timpy, USACE, in order to verify new wetland delineation
boundaries and resolve the project's drainage impacts that were computed by the ellipse
equation. Mr. John Hennessy, NCDWQ, declined to participate in the field review.
Following the review, Mr. Timpy contacted Mr. Hennessy by phone in order to verify the
resolved drainage impact issues. Mr. Hennessy concurred with Mr. Timpy's findings in
the field.
The USACE reviewed Sites 2, 8, 9, and 10 during the March 29, 2000 field review.
Drainage impacts originally computed by the ellipse equation were reviewed on Sites 2
and 8. The USACE verified newly delineated wetland boundaries on Sites 8 - 10.
Modeled wetland drainage impacts were eliminated at Sites 2 and 8 for the following four
reasons:
• The USACE does not consider the drainage impacts at the sites to be significant due
to the small size of the streams associated with each site's wetland.
• The existing and proposed invert elevations are nearly the same for each site. A -
0.033 ft (4010 m) change in invert elevation is proposed for the pipe outlet at Station
2
No. 27+75 left of -LRev- (Site 2). The NCDOT proposes a +0.755 ft (+0.230 m)
change in invert elevation at Station 42+20 right of -LRev- (Site 8).
The ellipse equation failed to correctly model the existing drainage conditions at both
sites.
The USACE felt that the project's remaining proposed drainage impacts modeled by
the ellipse equation represents a highly conservative estimate of such impacts.
Consequently, the agency felt that the project's remaining drainage impacts will more
than make up for the insignificant amount of wetland drainage impacts that will
actually occur at Sites 2 and 8.
Revised Jurisdictional Impacts to Waters of the United States (Wetlands/Surface Waters)
Wetlands
Wetland construction impacts for the R-2562AA/AB widening project were revised by
NCDOT after the environmental agencies authorized the project's CWA permits. The
AA and AB sections of R-2562 will now permanently impact 11.154 ac (4.514 ha) and
temporarily impact 0.743 ac (0.301 ha) of jurisdictional wetlands. Sections AA and AB
will together fill 6.444 ac (2.608 ha), excavate 0.956 ac (0.387 ha), drain 3.534 ac (1.430
ha), permanently clear ac 0.220 ac (0.089 ha), and temporarily clear 0.743 ac (0.301 ha)
of jurisdictional wetlands. The AA Section will permanently impact 8.881 ac (3.594 ha)
and temporarily impact 0.395 ac (0.160 ha) of jurisdictional wetlands. Jurisdictional
wetland impacts along the AB section of R-2562 remain the same as the originally
permitted impacts. Of the 11.154 ac of permanently impacted wetlands on the AA and
AB sections, 2.891 ac (1.170 ha) are considered riverine impacts, with the remaining
8.263 ac (3.344 ha) considered non-riverine impacts.
Table 2 depicts the revised jurisdictional wetland impacts for the AA and AB sections of
R-2562. Table 3 illustrates the revised jurisdictional wetland impacts for just the AA
section of the project. Permitted wetland impact areas originate from the project's CWA
§404 IP of March 7, 2000 and CWA §401 Water Quality Certification of February 22,
2000. The tables' shaded boxes represent revisions to the permitted wetland impacts
under a particular impact activity.

Tables A and B, located at the end of this permit modification application cover letter,
summarize the project's revised permanent and temporary jurisdictional wetland impacts
on a site-by-site and basis. These tables include information pertinent to each wetland
site, including station number, wetland type, riverine or non-riverine association,
NCDWQ rating (4`l' Version), Cowardin classification, and acreage impacts via fill,
excavation, drainage, permanent clearing, and temporary clearing. Table C, also located
at the end of this application cover letter, depicts the project's revised permanent and
temporary jurisdictional wetland impacts by community type.
According to page 4 of the revised February 17, 2000 IP application, NCDOT will utilize
Method II Mechanized Clearing for the entire project. Consequently, wetland vegetation
will only be cleared, rather than cleared and grubbed, on the project. With one exception,
all cleared wetland areas count toward temporary wetland impacts. The exception
pertains to cleared wetland areas that intersect drained wetland areas. Under this
scenario, all cleared wetland impact areas are considered permanently cleared wetland
impacts, and are depicted as such in the enclosed revised wetland/surface water impact
summary sheet (permit drawing 11 of 24, dated 5/22/00) and Tables A and C.
Site by Site Description of Revised Jurisdictional Wetland Impacts
Information is provided below on a newly proposed temporary work bridge across Site 1
of the AA section. Information is also provided for those sites (i.e., Sites 2 - 3 and 6 -
10) with revised wetland impacts. Tables 4 -10 summarize the revised jurisdictional
wetland impacts on a site by site basis. Permitted wetland impact areas originate from
the project's CWA §404 IP of March 7, 2000 and CWA §401 Water Quality Certification
of February 22, 2000. The tables' shaded boxes represent revised wetland impacts under
a particular impact activity.
Site 1 wetlands, AA Section (see enclosed permit drawings 12A and 12B of 24, dated 7/25/00)
In order to construct the permanent dual bridges over Rockfish Creek, NCDOT proposes
to construct, via top-down construction, a temporary work bridge across the stream. The
temporary work bridge will be constructed between the existing bridge and the new
southbound permanent bridge. The NCDOT will use the temporary work bridge for
4
equipment crossing during low water and/or construction activities. Construction of the
temporary work bridge will begin along the south bank of Rockfish Creek, and continue
northward until it joins the top of the stream's north bank. Once both permanent bridges
are completed, NCDOT will remove the temporary work bridge.
The temporary work bridge consists of a trestle type pier of steel H pilings capped with
appropriate strength material. The bridge will contain six bents that will be driven into
the substrate. A vibratory hammer will be used to pull out the piles when the temporary
bridge is removed. No earthen materials will be permitted into waters of the United
States. If NCDOT foresees earthen materials entering waters of the United States, as
defined under 33 CFR §328.3(a), steel sheet pilings will be installed on the upland area
abutments in order to prevent such an action from taking place.
The temporary work bridge consists of six bents. The first three bents (i. e., Bents 1- 3)
are proposed to be constructed in Rockfish Creek. Bent 4 will be constructed along the
south bank of Rockfish Creek along an upland area and the stream's edge. Bent 5 will be
constructed in the jurisdictional riverine wetland located at Site 1 of the AA section.
Bent 6 will be constructed in an upland area along creek's south bank.
Piles along Bent 5 of the temporary work bridge will temporarily impact jurisdictional
riverine wetlands at Site 1 (see permit drawing 12 of 24; June 1997). These temporary
wetland impacts occur when the piles are driven into the wetlands below. Once the piles
are removed, the temporarily impacted wetlands are expected to naturally revegetate.
The project's CWA permits already authorize a portion of Site 1's wetlands to be cleared
and, consequently, counted as a temporary wetland impact. The piles along Bent 5 of the
temporary work bridge occur in the same wetland area that was permitted to be cleared.
Consequently, NCDOT expects no additional permanent or temporary jurisdictional
wetland impacts to occur at Site 1 of the AA section beyond what is already authorized
under the project's CWA permits. See enclosed permit drawings 12A and 12B of 24
(dated 7/25/00) for a plan view, cross-section view, and bent-end view of the proposed
temporary work bridge.
Site 2 wetlands. AA Section (see enclosed revised permit drawing 13 of 24, dated 5/22/00)
Site 2's fill, excavation, temporary clearing, and total permanent wetland impacts
increased from the project's authorized permits. Wetland drainage impacts decreased as
compared to the same permits. Table 4 depicts the new wetland impacts. A discussion of
the impact changes follows the table.

Fill - Project design and depicted wetland fill area/limits did not change from Site 2's
permit drawing submitted with the February 17, 2000 CWA §§404/401 revised IP
application. The revised IP application contains an incorrectly calculated wetland fill
impact for Site 2. The enclosed revised wetland/surface water impact summary sheet
(permit drawing 11 of 24, dated 5/22/00) and Tables 4 and A correctly depict the new fill
impact.
Excavation - Project design and depicted wetland excavation area/limits did not change
from Site 2's permit drawing submitted with the February 17, 2000 CWA §§404/401 IP
application. The revised IP application contains an incorrectly calculated wetland
excavation impact for Site 2. Tables 4 and A and the enclosed revised wetland/surface
water impact summary sheet (permit drawing 11 of 24, dated 5/22/00) correctly depict the
new excavation impact.
Drainage - The site's originally modeled drainage impact was eliminated by USACE for
the reasons outlined in the "Environmental Agency Field Review" section of this permit
modification application letter. Enclosed revised permit drawing 13 of 24 (dated
5/22/00), revised wetland/surface water impact summary sheet (permit drawing 11 of 24,
dated 5/22/00), and Tables 4 and A correctly depict the new wetland drainage impacts at
Site 2.
Temporary clearing - Project design and depicted wetland clearing area/limits did not

Excavation - Permit drawing 13 of 24 (dated 2/17/00) associated with the project's CWA
§§404/401 permits incorrectly depict a portion of the wetland excavation impact as
occurring in the pond to be drained- This error was eliminated on the enclosed revised
permit drawing 13 of 24 (dated 5/22/00). The enclosed revised wetland/surface water
impact summary sheet (permit drawing 11 of 24, dated 5/22/00) and Tables 5 and A
correctly depict the new wetland excavation impact for Site 3.
Permanent clearing - Project design and depicted wetland clearing area/limits did not
change from Site 3's permit drawing (permit drawing 13 of 24, dated 2/17/00) associated
with the project's CWA §§404/401 permits. The February 17, 2000 revised IP
application contains an incorrectly calculated permanent wetland clearing impact for Site
3. Tables 5 and A and the enclosed revised wetland/surface water impact summary sheet
(permit drawing 11 of 24, dated 5/22/00) correctly depict the new permanent clearing
impact.
Site 6 wetlands. AA Section (see enclosed permit drawings 16 and 17 of 24, dated 2/17/00)
As compared to the project's original CWA §§404/401 permits, permanent clearing
wetland impacts increased and temporary clearing wetland impacts decreased at Site 6.

Permanent and temporary clearing - Project design and depicted wetland clearing
area/limits did not change from Site 7's permit drawing (permit drawings 19 of 24, dated
2/17/00) associated with the project's CWA §§404/401 permits. The February 17, 2000
revised IP application contains incorrectly calculated permanent and temporary wetland
clearing impacts for Site 7. Tables 7 and A and the enclosed revised wetland/surface

new permanent and temporary wetland clearing impacts.
Site 8 wetlands, AA Section (see enclosed revised permit drawing 19 of 24, dated 5/15/00)
As compared to the project's CWA §§404/401 permits, fill, drainage, permanent clearing,
and total permanent wetland impacts decreased at Site 8, while temporary clearing
wetland impacts increased. Table 8 depicts the new wetland impacts. A discussion of the
impact changes follows the table.

Fill - Project design and depicted wetland fill area/limits changed from Site 8's permit
drawing (permit drawing 19 of 24, dated 2/17/00) associated with the project's CWA
§§404/401 permits. The NCDOT utilized an incorrect wetland boundary file in its
February 17, 2000 revised IP application. Furthermore, a portion of the wetland was re-
delineated on March 13-15, 2000 by NCDOT and subsequently verified by USACE.
Enclosed revised permit drawing 19 of 24 (dated 5115100), revised wetland/surface water
impact summary sheet (permit drawing 11 of 24, dated 5/22/00), and Tables 8 and A
correctly depict the new wetland fill impacts at Site 8.
Drainage - The site's originally modeled and permitted drainage impact was eliminated
by USACE for the reasons outlined in the "Environmental Agency Field Review" section
of this permit modification application letter. Enclosed revised permit drawing 19 of 24
(dated 5115100), revised wetland/surface water impact summary sheet (permit drawing 11
of 24, dated 5/22/00), and Tables 8 and A correctly depict the new wetland fill impacts at
Site 8.
Permanent and temporary clearing - All permanent clearing wetland impacts that
intersected the site's permitted drainage impacts are now counted as temporary clearing
impacts because USACE eliminated the site's drainage impacts. Tables 8 and A and the
enclosed revised wetland/surface water impact summary sheet (permit drawing I 1 of 24,
dated 5/22/00) correctly depict the new permanent and temporary wetland clearing
impacts.

Drainage - Wetland drainage impacts calculated from the ellipse equation initially
extended beyond the originally delineated wetland boundaries. During the project's
March 13-15, 2000 wetland delineations, Site 9's wetland boundaries were extended out
past the drainage impact "circle" calculated by the ellipse equation. This drainage impact
"circle" was then extended to encompass the additional wetlands at the site. Enclosed

Permanent clearing - Project design and depicted wetland clearing area/limits did not
change from Site 9's permit drawing (permit drawing 20 of 24, dated 2/17/00) associated
with the project's CWA §§404/401 permits. The February 17, 2000 revised IP
application contains an incorrectly calculated permanent wetland clearing impact for Site
9. Tables 9 and A and the enclosed revised wetland/surface water impact summary sheet

Fill - The NCDOT utilized an incorrect wetland boundary file in its February 17, 2000
revised IP application. This specifically affects the site's eastern jurisdictional wetland
boundary. Furthermore, the February 17, 2000 revised IP application contains an
incorrectly depicted wetland fill area along the western portion of the site's fill limits.
Enclosed revised permit drawing 20B of 24 (dated 5115100), revised wetland/surface
water impact summary sheet (permit drawing 11 of 24 dated 5/22/00), and Tables 10 and
A correctly depict the new wetland fill impacts at Site 10.
Excavation and drainage - Site 10's wetland boundaries were re-delineated by NCDOT
on March 13-15, 2000 and subsequently verified by USACE. In order to eliminate the
site's wetland drainage impacts depicted on the project's CWA §§404/401 permits,
NCDOT Hydraulics Unit eliminated the proposed jurisdictional stream relocation through
the site's wetlands. This subsequently eliminated the site's wetland excavation impacts.
Enclosed revised permit drawing 20B of 24 (dated 5115100), revised wetland/surface
water impact summary sheet (permit drawing 11 of 24, dated 5/22/00), and Tables 10 and

Permanent and temporary clearing - All clearing impacts depicted on this site's permit
drawing (permit drawing 20 of 24, dated 2/17/00) associated with the project's CWA
§§404/401 permits were considered permanent wetland impacts because the site's
drainage impacts intersected the clearing impacts. Since the wetland drainage impacts at
Site 10 were eliminated, all permanent clearing impacts no longer insect the drainage
impacts and are, therefore, considered temporary clearing impacts. The site's total
wetland clearing impacts (i.e., permanent + temporary clearing) have decreased from the
project's CWA permits because the site's proposed relocated stream channel was
eliminated. Additional clearing impacts were incorporated around this proposed channel.
Enclosed revised permit drawing 20B of 24 (dated 5/15/00), revised wetland/surface

Surface Waters
After the environmental agencies authorized the environmental permits for R-
2562AA/AB, NCDOT revised the surface water construction impacts on the widening
project. The AA and AB sections of R-2562 will together fill 0.619 ac (0.251 ha) of
surface waters (i.e., ponds), impact 1,470 linear ft (448 m) of existing stream channel, and
relocate 476 linear ft (145 m) of stream channel. Per the project's CWA §§404/401
permits, the 476 linear ft of relocated channels count toward on-site stream mitigation.
Consequently, the entire project will result in 994 linear ft (303 m) of stream channel
loss. The AA section of R-2562A will fill 0.321 ac (0.130 ha) of surface waters (i.e.,
ponds), impact 1,079 linear ft (329 m) of existing stream channel, and relocate 476 linear
ft (145 m) of stream channel. Per the project's CWA §§404/401 permits, the 476 linear ft
of relocated channels count toward on-site stream mitigation. Consequently, the AA
section will result in 603 linear ft (184 m) of stream channel loss. The AB section's fill
in surface waters (i.e., ponds), impacted existing stream channel (listed as "stream
channel loss" in Table 5 of the project's April 14, 1999 CWA §§404/401 IP application),
and relocated stream channel equate to the area and linear distances authorized under the
project's CWA §§404/401 permits for that section of R-2562.
Table 11 depicts the revised jurisdictional surface water impacts for the AA and AB
sections of R-2562. Table 12 illustrates the revised jurisdictional surface water impacts
for just the AA section of the project. Permitted surface water impact area and linear
distances originate from the project's CWA §404 IP of March 7, 2000 and CWA §401
Water Quality Certification of February 22, 2000. The tables' shaded boxes represent

Site 3 surface waters, AA section (see enclosed revised permit drawing 13 of 24, dated 5/22/00)
The NCDOT is relocating an unnamed jurisdictional stream through an existing pond at
Site 3. The project's CWA §§404/401 permits authorize the fill of 0.158 ac (0.064 ha) of
the site's pond. Since the relocated jurisdictional stream will drain the remaining portion
of the pond not authorized to be filled, NCDOT Hydraulics Unit counted the entire pond
area as a fill in surface water impact. Enclosed revised permit drawing 13 of 24 (dated
5/22/00) illustrates the drained pond. The enclosed revised wetland/surface water impact
summary sheet (permit drawing 11 of 24, dated 5/22/00), and Tables 13 and D correctly

The linear distance of existing channel impacted has not changed from the project's
original CWA §§404/401 permits. Existing channel impact of 13 linear ft (4 m) wasn't
included as part of Site 9's channel impacts on the project's April 14, 1999 permit
application and subsequently issued permits. This total was, however, accounted for in
the initial permit application and permits under the amount of required compensatory off-
site stream mitigation. An additional 13 linear ft of stream channel impacts at Site 9
appear in Tables 14 and D solely for accounting purposes.

Site 10 surface waters, AA Section (see enclosed revised permit drawing 20B of 24, dated 5/22/00)
Site 10 is an unnamed stream associated with Murphy Swamp. In order to reduce this
site's initially proposed 1.666 ac (0.674 ha) of wetland drainage impacts, NCDOT
Hydraulics Unit eliminated the relocated channel that drained the site's wetlands. A 1500
mm reinforced concrete pipe measuring 131 ft (40 m) in length will now convey water
along Site 1 O's jurisdictional stream, instead of the initially permitted 164 linear ft (50 m)
of relocated stream channel. The project's CWA §§404/401 permits counted the initially
proposed 164 linear ft of relocated stream channel as compensatory on-site stream
mitigation. The NCDOT proposes to compensate for the lost 164 linear ft of on-site
stream mitigation through an additional 328 linear ft (100 m) off-site stream mitigation at
a 2:1 ratio. Enclosed revised permit drawing 20B of 24 (dated 5/22/00) illustrates the
14
revised hydraulic conveyance at Site 10. The enclosed revised wetland/surface water

Compensatory Wetland/Stream Mitigation
Wetland Mitigation
The NCDOT Project Development and Environmental Analysis Branch proposes to
revise the project's permitted compensatory wetland mitigation from Dowd Dairy Farm
Mitigation Site. The mitigation site is located in north central Bladen County,
approximately 7 miles (11 km) north of Elizabethtown and 2 miles (3 km) east of White
Oak. State Route (SR) 1324 (Dowd Dairy Farm Road) borders the site to the north, SR
1332 (Oak Grove Church Road) lies to the west, and dense forest is situated south and
east of the site. The site, which sits along a Coastal Plain interstream divide between
Ellis Creek to the west and Palmer Branch to the east, falls within the Cape Fear River
subbasin 03-06-16 and Hydrologic Unit #03030005. The wetland and surface water
impacts associated with R-2562AA/AB fall within the Cape Fear River subbasins 03-06-
15 and 03-06-16 and Hydrologic Unit #03030004 and #03030005.
Dowd Dairy Farm Mitigation Site consists of approximately 638 ac (258 ha) of prior-
converted (PC) cropland and approximately 20 ac (8 ha) of cropland on non-hydric soils.
Prior-converted cropland is a wetland that was manipulated and cropped prior to 23
December 1985 to the extent that it no longer exhibits important wetland functions.
Prior-converted croplands do not fall under the regulatory jurisdiction of CWA §404.
Compensatory wetland mitigation credits for the Dowd Dairy Farm Mitigation Site are
based on wetland functions generated by restoration and comparison of restored functions
to impacted wetland resources. A base-line estimated mitigation plan for the site includes
13 ac (5 ha) of restored riverine (headwater) wetlands, 518 ac (210 ha) of restored non-
riverine wetlands, 20 ac (8 ha) of restored wetland/upland ecotones, and 107 ac (43 ha) of
restored wetland buffers that are adjacent to perimeter canals. The NCDOT's Wetland
Mitigation Plan: Dowd Dairy Farm Wetlands, Bladen County, North Carolina (May
1997) contains further information on this mitigation site.
15
Site construction for Dowd Dairy Mitigation Site is divided into two parts, Phase I and
Phase II.. Phase I consisted of clearing/grubbing/ripping most of the site, filling lateral
ditches, and adding ditch plugs. The NCDOT completed construction activities under
Phase I in September 1998. Planting for the first phase was completed in March 1999.
All monitoring wells were installed during Phase I. The NCDOT is conducting on-going
hydrologic monitoring at the mitigation site. Activities conducted under the second phase
of construction will include filling the central channel and installing related ditch plugs.
Phase II construction activities began during the summer of 1999, were halted for an
extended period of time due to wetness from several hurricanes, and will be completed by
the summer of 2000. The final planting for Phase II will be completed by March 2001.
In order to offset 11.154 ac (4.514) ha of permanent wetland impacts associated with the
project, NCDOT proposes to debit 5.8 ac (2.3 ha) of restored riverine wetlands and 16.4
ac (6.6 ha) of restored non-riverine wetlands from Dowd Dairy Farm Mitigation Site.
This project is one of three NCDOT projects that use a portion of Dowd Dairy Farm
Mitigation Site for compensatory wetland mitigation. The other two NCDOT projects
that utilize the mitigation site are R-2238AA/ABBA (NC 87 in Cumberland and Harnett
Counties) and R-2204A (NC 11 in Duplin County). Tables 16 and 17 update the R-
2562AA/AB compensatory wetland mitigation requirements authorized in the project's
CWA §§404/401 permits. Table 16 summarizes the compensatory wetland mitigation
proposal for R-2562AA/AB. Table 17 outlines the accumulative compensatory wetland
mitigation taken from Dowd Dairy Farm Mitigation Site. Revised mitigation debit ledger
maps and x-y coordinates of Dowd Dairy Farm Mitigation Site are also included as an
attachment to this permit modification application letter.

Stream Mitigation
According to Table D, the project impacts 1,470 linear ft (448 m) of existing stream
channel and relocates 476 linear ft (145 m) of stream channel. Per the project's CWA o,
§ §404/401 permits, the 476 linear ft of relocated channels count toward 1:1 on-site stream lrc. -
mitigation. After subtracting out the project's revised on-site site stream mitigation "cgs
credits, the entire project will result in 994 linear ft (303 m) of stream channel loss (i. e., A z al?S?t
1,470 linear ft existing stream channel impacted - 476 linear ft relocated stream channel 9? rty?N.l
as on-site stream mitigation = 994 linear ft stream channel loss). In order to offset the
stream loss, NCDOT proposes to mitigate for 1,988 linear ft (606 m) of streams under its - 32? wR
2:1 off-site compensatory stream mitigation requirements. P _
The project's CWA permits authorize compensatory off-site stream mitigation for 1,660
linear ft (506 m). Per a letter dated June 12, 2000, NC Wetlands Restoration Program
(NCWRP) received check number. 1016493 in the amount of $207,500 as payment for the
compensatory off-site stream mitigation requirements authorized under the project's
CWA §§404/401 permits. As specified under the project's CWA permits, NCWRP will
restore 1,660 linear ft (506 m) of jurisdictional stream in Cataloging Unit 0303004 of the
Cape Fear River Basin.
The NCDOT lost 164 linear ft (50 m) of permitted on-site stream mitigation because of
the additional 1500 mm reinforced concrete pipe proposed for Site 10's jurisdictional
stream along the AA section of the project. Therefore, NCDOT proposes to compensate
for the lost on-site stream mitigation through an additional 328 linear ft (100 m) off-site
stream mitigation at a 2:1 ratio. The additional 328 linear ft of off-site stream mitigation
plus the permitted 1,660 ft of off-site stream mitigation provided by NCWRP comprise
the project's revised off-site stream mitigation figure of 1,988 linear ft now required for
R-2562AA/AB. In a letter dated September 6,2000, NCDOT requested from NCWRP
an additional 328 linear ft of off-site stream mitigation to compensate for the lost on-site
stream mitigation. At a cost of $125 per stream mitigation unit, NCDOT proposes to pay
NCWRP an additional $41,000 for compensatory stream mitigation.

Authorization Request
In summary, construction of the proposed NC 87 widening will permanently impact
11.154 ac (4.514 ha) and temporarily impact 0.743 ac (0.301 ha) of jurisdictional
wetlands, fill 0.619 ac (0.251 ha) of surface waters (i.e., ponds), impact 1,470 linear ft
(448 m) of existing stream channel, and relocate 476 linear ft (145 m) of stream channel.
Per the project's CWA §§404/401 permits, the 476 linear ft of relocated channels count
toward on-site stream mitigation. Consequently, the entire project will result in 994
linear ft (303 m) of stream channel loss. In order to offset jurisdictional wetland impacts,
NCDOT proposes to provide 5.8 (2.3) of restored riverine wetlands and 16.4 ac (6.6 ha)
of restored non-riverine wetlands from Dowd Dairy Farm Mitigation Site. In order to
compensate for 164 linear ft (50 m) of lost on-site stream mitigation, NCDOT also
proposes to pay NCWRP an additional $41,000 for compensatory off-site stream
mitigation.
Based upon the revised impacts to jurisdictional wetlands and streams and revised
compensatory wetland and stream mitigation, NCDOT requests authorization to modify
the project's CWA §404 IP of March 7, 2000 and CWA §401 Water Quality Certification
of February 22, 2000 in order to continue constructing the project. Enclosed are revised
permit drawings and wetland mitigation debit ledger maps that depict the project's
updated wetland and stream impacts and compensatory wetland mitigation requirements.
A $475 check addressed to NCDWQ is also enclosed for application to a CWA §401
Water Quality. Certification modification. If you have any questions or need additional
information, please call Mr. Tim Bassette at [phone] 005.
Sincerely,

William D. Gilmore, P.E., Manager

Attention: Mr. Dave Timpy
NCDOT Project Coordinator
Subject: NC 87, from I-95 to NC 20, Bladen and Cumberland Counties, State
Project No. 6.439001T, TIP No. R-2562AA/AB; USACE Action
ID 199304806; DQC Project No. 990340.
Dear Sir:
This North Carolina Department of Transportation (NCDOT) applicationromses to
modify the March 7, 2000 Clean Water Act (CWA) §404 IP and February 22, 2000
CWA $401 Water Oualitv Certification for TIP No. R-2562AA/AB_(NC 87). The entire
R-2562 project consists of widening and improving NC 87 from its existing two-lane
section to a four-lane divided section with a 46-ft (14-m) wide grass median. The 28 mi
(45 km) long project begins east of I-95 in Cumberland County and ends at the
NC 87/Elizabethtown Bypass in Bladen County.
Project Breakdown and Construction Schedule
For construction purposes, NCDOT divides the R-2562 project into five sections: AA,
AB, B, C, and D. The NCDOT completed construction on the B section of R-2562 in
December 1999. The project impacted 0.30 ac (0.12 ha) of wetlands and was authorized
under CWA §404 Nationwide Permit No. 26 (US Army Corps of Engineers Action ID
199704613, NC Division of Water Quality Project No. 97101). The NCDOT began
constructing the AA and AB sections of the project in April 2000. The Project
Breakdown Map for R-2562, located at the end of this permit application modification
letter, illustrates each section of the project. Table 1 contains information concerning the
construction schedule, length, and termini of each section.

Project History for R-2562AA/AB
On April 14, 1999, NCDOT submitted a CWA §404 permit application to the US Army
Corps of Engineers (USACE) for an Individual Permit (IP) and the NC Division of Water
Quality (NCDWQ) for a CWA §401 Water Quality Certification. The April 14, 1999
permit application was placed on Public Notice on June 3, 1999. In a letter dated August
13, 1999, NCDWQ placed the April 14, 1999 permit application on hold. On February
17, 2000, NCDOT submitted a revised IP application that updated the initial April 1999
permit application. The NCDOT was authorized to construct the AA and AB sections of
R-2562 by a CWA §404 IP (Permit No. 199304806) from the USACE and a CWA §401
Water Quality Certification No. 3268 (Project No. 990340) from the NCDWQ. The
permit and water quality certification authorized NCDOT to drain, excavate, clear, or
discharge fill material into 13.508 ac (5.466 ha) of jurisdictional wetlands. The project's
permits also authorize NCDOT to discharge fill into 1,467 linear ft (447 m) of
jurisdictional stream associated with the Cape Fear River and its tributaries.
Environmental Agency Field Review
In order to complete the project's final wetland/stream design files and resolve the
project's drainage impacts, NCDOT natural system specialists Mr. Tim Bassette, Mr.
Jared Gray, and Mr. Chris Murray conducted a wetland delineation and drainage impact
field review along several sites of R-2562AA. The project's biological fieldwork was
completed March 13-15, 2000. On March 29, 2000, Mr. Bassette held an environmental
field review with Mr. Dave Timpy, USACE, in order to verify new wetland delineation
boundaries and resolve the project's drainage impacts that were computed by the ellipse
equation. Mr. John Hennessy, NCDWQ, declined to participate in the field review.
Following the review, Mr. Timpy contacted Mr. Hennessy by phone in order to verify the
resolved drainage impact issues. Mr. Hennessy concurred with Mr. Timpy's findings in
the field.
The USACE reviewed Sites 2, 8, 9, and 10 during the March 29, 2000 field review.
Drainage impacts originally computed by the ellipse equation were reviewed on Sites 2
and 8. The USACE verified newly delineated wetland boundaries on Sites 8 - 10.
Modeled wetland drainage impacts were eliminated at Sites 2 and 8 for the following four
reasons:
• The USACE does not consider the drainage impacts at the sites to be significant due
to the small size of the streams associated with each site's wetland.
• The existing and proposed invert elevations are nearly the same for each site. A -
0.033 ft (4010 m) change in invert elevation is proposed for the pipe outlet at Station
2
No. 27+75 left of -LRev- (Site 2). The NCDOT proposes a +0.755 ft (+0.230 m)
change in invert elevation at Station 42+20 right of -LRev- (Site 8).
• The ellipse equation failed to correctly model the existing drainage conditions at both
sites.
• The USACE felt that the project's remaining proposed drainage impacts modeled by
the ellipse equation represents a highly conservative estimate of such impacts.
Consequently, the agency felt that the project's remaining drainage impacts will more
than make up for the insignificant amount of wetland drainage impacts that will
actually occur at Sites 2 and 8.
Revised Jurisdictional Impacts to Waters of the United States (Wetlands/Surface Waters)
Wetlands
Wetland construction impacts for the R-2562AA/AB widening project were revised by
NCDOT after the environmental agencies authorized the project's CWA permits. The
AA and AB sections of R-2562 will now permanently impact 11.154 ac (4.514 ha) and
temporarily impact 0.743 ac (0.301 ha) of jurisdictional wetlands. Sections AA and AB
will together fill 6.444 ac (2.608 ha), excavate 0.956 ac (0.387 ha), drain 3.534 ac (1.430
ha), permanently clear ac 0.220 ac (0.089 ha), and temporarily clear 0.743 ac (0.301 ha)
of jurisdictional wetlands. The AA Section will permanently impact 8.881 ac (3.594 ha)
and temporarily impact 0.395 ac (0.160 ha) of jurisdictional wetlands. Jurisdictional
wetland impacts along the AB section of R-2562 remain the same as the originally
permitted impacts. Of the 11.154 ac of permanently impacted wetlands on the AA and
AB sections, 2.891 ac (1.170 ha) are considered riverine impacts, with the remaining
8.263 ac (3.344 ha) considered non-riverine impacts.
Table 2 depicts the revised jurisdictional wetland impacts for the AA and AB sections of
R-2562. Table 3 illustrates the revised jurisdictional wetland impacts for just the AA
section of the project. Permitted wetland impact areas originate from the project's CWA
§404 IP of March 7, 2000 and CWA §401 Water Quality Certification of February 22,
2000. The tables' shaded boxes represent revisions to the permitted wetland impacts
under a particular impact activity.

Tables A and B, located at the end of this permit modification application cover letter,
summarize the project's revised permanent and temporary jurisdictional wetland impacts
on a site-by-site and basis. These tables include information pertinent to each wetland
site, including station number, wetland type, riverine or non-riverine association,
NCDWQ rating (4' Version), Cowardin classification, and acreage impacts via fill,
excavation, drainage, permanent clearing, and temporary clearing. Table C, also located
at the end of this application cover letter, depicts the project's revised permanent and
temporary jurisdictional wetland impacts by community type.
According to page 4 of the revised February 17, 2000 IP application, NCDOT will utilize
Method II Mechanized Clearing for the entire project. Consequently, wetland vegetation
will only be cleared, rather than cleared and grubbed, on the project. With one exception,
all cleared wetland areas count toward temporary wetland impacts. The exception
pertains to cleared wetland areas that intersect drained wetland areas. Under this
scenario, all cleared wetland impact areas are considered permanently cleared wetland
impacts, and are depicted as such in the enclosed revised wetland/surface water impact
summary sheet (permit drawing 11 of 24, dated 5/22/00) and Tables A and C.
Site by Site Description of Revised Jurisdictional Wetland Impacts
Information is provided below on a newly proposed temporary work bridge across Site 1
of the AA section. Information is also provided for those sites (i. e., Sites 2 - 3 and 6 -
10) with revised wetland impacts. Tables 4 -10 summarize the revised jurisdictional
wetland impacts on a site by site basis. Permitted wetland impact areas originate from
the project's CWA §404 IP of March 7, 2000 and CWA §401 Water Quality Certification
of February 22, 2000. The tables' shaded boxes represent revised wetland impacts under
a particular impact activity.
Site 1 wetlands, AA Section (see enclosed permit drawings 12A and 12B of 24, dated 7/25/00)
In order to construct the permanent dual bridges over Rockfish Creek, NCDOT proposes
to construct, via top-down construction, a temporary work bridge across the stream. The
temporary work bridge will be constructed between the existing bridge and the new
southbound permanent bridge. The NCDOT will use the temporary work bridge for
4
equipment crossing during low water and/or construction activities. Construction of the
temporary work bridge will begin along the south bank of Rockfish Creek, and continue
northward until it joins the top of the stream's north bank. Once both permanent bridges
are completed, NCDOT will remove the temporary work bridge.
The temporary work bridge consists of a trestle type pier of steel H pilings capped with
appropriate strength material. The bridge will contain six bents that will be driven into
the substrate. A vibratory hammer will be used to pull out the piles when the temporary
bridge is removed. No earthen materials will be permitted into waters of the United
States. If NCDOT foresees earthen materials entering waters of the United States, as
defined under 33 CFR §328.3(a), steel sheet pilings will be installed on the upland area
abutments in order to prevent such an action from taking place.
The temporary work bridge consists of six bents. The first three bents (i.e., Bents 1- 3)
are proposed to be constructed in Rockfish Creek. Bent 4 will be constructed along the
south bank of Rockfish Creek along an upland area and the stream's edge. Bent 5 will be
constructed in the jurisdictional riverine wetland located at Site 1 of the AA section.
Bent 6 will be constructed in an upland area along creek's south bank.
Piles along Bent 5 of the temporary work bridge will temporarily impact jurisdictional
riverine wetlands at Site 1 (see permit drawing 12 of 24; June 1997). These temporary
wetland impacts occur when the piles are driven into the wetlands below. Once the piles
are removed, the temporarily impacted wetlands are expected to naturally revegetate.
The project's CWA permits already authorize a portion of Site 1's wetlands to be cleared
and, consequently, counted as a temporary wetland impact. The piles along Bent 5 of the
temporary work bridge occur in the same wetland area that was permitted to be cleared.
Consequently, NCDOT expects no additional permanent or temporary jurisdictional
wetland impacts to occur at Site 1 of the AA section beyond what is already authorized
under the project's CWA permits. See enclosed permit drawings 12A and 12B of 24
(dated 7/25/00) for a plan view, cross-section view, and bent-end view of the proposed
temporary work bridge.
Site 2 wetlands, AA Section (see enclosed revised permit drawing 13 of 24, dated 5/22/00)
Site 2's fill, excavation, temporary clearing, and total permanent wetland impacts
increased from the project's authorized permits. Wetland drainage impacts decreased as
compared to the same permits. Table 4 depicts the new wetland impacts. A discussion of
the impact changes follows the table.

Fill - Project design and depicted wetland fill area/limits did not change from Site 2's
permit drawing submitted with the February 17, 2000 CWA §§404/401 revised IP
application. The revised IP application contains an incorrectly calculated wetland fill
impact for Site 2. The enclosed revised wetland/surface water impact summary sheet
(permit drawing 11 of 24, dated 5/22/00) and Tables 4 and A correctly depict the new fill
impact.
Excavation - Project design and depicted wetland excavation area/limits did not change
from Site 2's permit drawing submitted with the February 17, 2000 CWA §§404/401 IP
application. The revised IP application contains an incorrectly calculated wetland
excavation impact for Site 2. Tables 4 and A and the enclosed revised wetland/surface
water impact summary sheet (permit drawing 11 of 24, dated 5/22/00) correctly depict the
new excavation impact.
Drainage - The site's originally modeled drainage impact was eliminated by USACE for
the reasons outlined in the "Environmental Agency Field Review" section of this permit
modification application letter. Enclosed revised permit drawing 13 of 24 (dated ,
5/22/00), revised wetland/surface water impact summary sheet (permit drawing 11 of 24,

Excavation - Permit drawing 13 of 24 (dated 2/17/00) associated with the project's CWA
§ §404/401 permits incorrectly depict a portion of the wetland excavation impact as
occurring in the pond to be drained. This error was eliminated on the enclosed revised
permit drawing 13 of 24 (dated 5/22/00). The enclosed revised wetland/surface water
impact summary sheet (permit drawing 11 of 24, dated 5/22/00) and Tables 5 and A

Fill - Project design and depicted wetland fill area/limits changed from Site 8's permit
drawing (permit drawing 19 of 24, dated 2/17/00) associated with the project's CWA
§§404/401 permits. The NCDOT utilized an incorrect wetland boundary file in its
February 17, 2000 revised IP application. Furthermore, a portion of the wetland was re-
delineated on March 13-15, 2000 by NCDOT and subsequently verified by USACE.
Enclosed revised permit drawing 19 of 24 (dated 5115100), revised wetland/surface water
impact summary sheet (permit drawing 11 of 24, dated 5/22/00), and Tables 8 and A

Drainage - The site's originally modeled and permitted drainage impact was eliminated
by USACE for the reasons outlined in the "Environmental Agency Field Review" section
of this permit modification application letter. Enclosed revised permit drawing 19 of 24
(dated 5115100), revised wetland/surface water impact summary sheet (permit drawing 11

Site 8.
Permanent and temporary clearing - All permanent clearing wetland impacts that
intersected the site's permitted drainage impacts are now counted as temporary clearing
impacts because USACE eliminated the site's drainage impacts. Tables 8 and A and the
enclosed revised wetland/surface water impact summary sheet (permit drawing 11 of 24,

Drainage - Wetland drainage impacts calculated from the ellipse equation initially
extended beyond the originally delineated wetland boundaries. During the project's
March 13-15, 2000 wetland delineations, Site 9's wetland boundaries were extended out
past the drainage impact "circle" calculated by the ellipse equation. This drainage impact
"circle" was then extended to encompass the additional wetlands at the site. Enclosed

Fill - The NCDOT utilized an incorrect wetland boundary file in its February 17, 2000
revised IP application. This specifically affects the site's eastern jurisdictional wetland
boundary. Furthermore, the February 17, 2000 revised IP application contains an
incorrectly depicted wetland fill area along the western portion of the site's fill limits.

Excavation and drainage - Site 10's wetland boundaries were re-delineated by NCDOT
on March 13-15, 2000 and subsequently verified by USAGE. In order to eliminate the
site's wetland drainage impacts depicted on the project's CWA §§404/401 permits,
NCDOT Hydraulics Unit eliminated the proposed jurisdictional stream relocation through
the site's wetlands. This subsequently eliminated the site's wetland excavation impacts.

drawing (permit drawing 20 of 24, dated 2/17/00) associated with the project's CWA
§§404/401 permits were considered permanent wetland impacts because the site's
drainage impacts intersected the clearing impacts. Since the wetland drainage impacts at
Site 10 were eliminated, all permanent clearing impacts no longer insect the drainage
impacts and are, therefore, considered temporary clearing impacts. The site's total
wetland clearing impacts (i. e., permanent + temporary clearing) have decreased from the
project's CWA permits because the site's proposed relocated stream channel was
eliminated. Additional clearing impacts were incorporated around this proposed channel.
Enclosed revised permit drawing 20B of 24 (dated 5115100), revised wetland/surface
water impact summary sheet (permit drawing 11 of 24, dated 5/22/00), and Tables 10 and
A correctly depict the new permanent and temporary wetland clearing impacts at Site 10.

Surface Waters
After the environmental agencies authorized the environmental permits for R-
2562AA/AB, NCDOT revised the surface water construction impacts on the widening
project: The AA and AB sections of R-2562 will together fill 0.619 ac (0.251 ha) of
surface waters (i.e., ponds), impact 1,470 linear ft (448 m) of existing stream channel, and
relocate 476 linear ft (145 m) of stream channel. Per the project's CWA §§404/401
permits, the 476 linear ft of relocated channels count toward on-site stream mitigation.
Consequently, the entire project will result in 994 linear ft (303 m) of stream channel
loss. The AA section of R-2562A will fill 0.321 ac (0.130 ha) of surface waters (i.e.,
ponds), impact 1,079 linear ft (329 m) of existing stream channel, and relocate 476 linear
ft (145 m) of stream channel. Per the project's CWA §§404/401 permits, the 476 linear ft
of relocated channels count toward on-site stream mitigation. Consequently, the AA
section will result in 603 linear ft (184 m) of stream channel loss. The AB section's fill
in surface waters (i.e., ponds), impacted existing stream channel (listed as "stream
channel loss" in Table 5 of the project's April 14, 1999 CWA §§404/401 IP application),
and relocated stream channel equate to the area and linear distances authorized under the
project's CWA §§404/401 permits for that section of R-2562.
Table 11 depicts the revised jurisdictional surface water impacts for the AA and AB
sections of R-2562. Table 12 illustrates the revised jurisdictional surface water impacts
for just the AA section of the project. Permitted surface water impact area and linear
distances originate from the project's CWA §404 IP of March 7, 2000 and CWA §401
Water Quality' Certification of February 22, 2000. The tables' shaded boxes represent
revisions to the permitted surface water impacts under a particular impact activity.

Site 3 surface waters. AA section (see enclosed revised permit drawing 13 of 24, dated 5/22/00)
The NCDOT is relocating an unnamed jurisdictional stream through an existing pond at
Site 3. The project's CWA §§404/401 permits authorize the fill of 0.158 ac (0.064 ha) of
the site's pond. Since the relocated jurisdictional stream will drain the remaining portion
of the pond not authorized to be filled, NCDOT Hydraulics Unit counted the entire pond
area as a fill in surface water impact. Enclosed revised permit drawing 13 of 24 (dated
5/22/00) illustrates the drained pond. The enclosed revised wetland/surface water impact
summary sheet (permit drawing 11 of 24, dated 5/22/00), and Tables 13 and D correctly

Site 9 surface waters, AA Section (see enclosed revised permit drawing 20A of 24, dated 5115100)
The linear distance of existing channel impacted has not changed from the project's
original CWA §§404/401 permits. Existing channel impact of 13 linear ft (4 m) wasn't
included as part of Site 9's channel impacts on the project's April 14, 1999 permit
application and subsequently issued permits. This total was, however, accounted for in
the initial permit application and permits under the amount of required compensatory off-
site stream mitigation. An additional 13 linear ft of stream channel impacts at Site 9
appear in Tables 14 and D solely for accounting purposes.

Site 10 surface waters, AA Section (see enclosed revised permit drawing 20B of 24, dated 5/22/00)
Site 10 is an unnamed stream associated with Murphy Swamp. In order to reduce this
site's initially proposed 1.666 ac (0.674 ha) of wetland drainage impacts, NCDOT
Hydraulics Unit eliminated the relocated channel that drained the site's wetlands. A 1500
mm reinforced concrete pipe measuring 131 ft (40 m) in length will now convey water
along Site 10's jurisdictional stream, instead of the initially permitted 164 linear ft (50 m)
of relocated stream channel. The project's CWA §§404/401 permits counted the initially
proposed 164 linear ft of relocated stream channel as compensatory on-site stream
mitigation. The NCDOT proposes to compensate for the lost 164 linear ft of on-site
stream mitigation through an additional 328 linear ft (100 m) off-site stream mitigation at
a 2:1 ratio. Enclosed revised permit drawing 20B of 24 (dated 5/22/00) illustrates the
14
revised hydraulic conveyance at Site 10. The enclosed revised wetland/surface water
impact summary sheet (permit drawing 11 of 24, dated 5/22/00) and Tables 15 and D

Compensatory Wetland/Stream Mitigation
Wetland Mitigation
The NCDOT Project Development and Environmental Analysis Branch proposes to
revise the project's permitted compensatory wetland mitigation from Dowd Dairy Farm
Mitigation Site. The mitigation site is located in north central Bladen County,
approximately 7 miles (11 km) north of Elizabethtown and 2 miles (3 km) east of White
Oak. State Route (SR) 1324 (Dowd Dairy Farm Road) borders the site to the north, SR
1332 (Oak Grove Church Road) lies to the west, and dense forest is situated south and
east of the site. The site, which sits along a Coastal Plain interstream divide between
Ellis Creek to the west and Palmer Branch to the east, falls within the Cape Fear River
subbasin 03-06-16 and Hydrologic Unit #03030005. The wetland and surface water
impacts associated with R-2562AA/AB fall within the Cape Fear River subbasins 03-06-
15 and 03-06-16 and Hydrologic Unit #03030004 and #03030005.
Dowd Dairy Farm Mitigation Site consists of approximately 638 ac (258 ha) of prior-
converted (PC) cropland and approximately 20 ac (8 ha) of cropland on non-hydric soils.
Prior-converted cropland is a wetland that was manipulated and cropped prior to 23
December 1985 to the extent that it no longer exhibits important wetland functions.
Prior-converted croplands do not fall under the regulatory jurisdiction of CWA §404.
Compensatory wetland mitigation credits for the Dowd Dairy Farm Mitigation Site are
based on wetland functions generated by restoration and comparison of restored functions
to impacted wetland resources. A base-line estimated mitigation plan for the site includes
13 ac (5 ha) of restored riverine (headwater) wetlands, 518 ac (210 ha) of restored non-
riverine wetlands, 20 ac (8 ha) of restored wetland/upland ecotones, and 107 ac (43 ha) of
restored wetland buffers that are adjacent to perimeter canals. The NCDOT's Wetland
Mitigation Plan: Dowd Dairy Farm Wetlands, Bladen County, North Carolina (May
1997) contains further information on this mitigation site.
15
Site construction for Dowd Dairy Mitigation Site is divided into two parts, Phase I and
Phase II. Phase I consisted of clearing/grubbing/ripping most of the site, filling lateral
ditches, and adding ditch plugs. The NCDOT completed construction activities under
Phase I in September 1998. Planting for the first phase was completed in March 1999.
All monitoring wells were installed during Phase I. The NCDOT is conducting on-going
hydrologic monitoring at the mitigation site. Activities conducted under the second phase
of construction will include filling the central channel and installing related ditch plugs.
Phase II construction activities began during the summer of 1999, were halted for an
extended period of time due to wetness from several hurricanes, and will be completed by
the summer of 2000. The final planting for Phase II will be completed by March 2001.
In order to offset 11.154 ac (4.514) ha of permanent wetland impacts associated with the
project, NCDOT proposes to debit 5.8 ac (2.3 ha) of restored riverine wetlands and 16.4
ac (6.6 ha) of restored non-riverine wetlands from Dowd Dairy Farm Mitigation Site.
This project is one of three NCDOT projects that use a portion of Dowd Dairy Farm
Mitigation Site for compensatory wetland mitigation. The other two NCDOT projects
that utilize the mitigation site are R-2238AA/ABBA (NC 87 in Cumberland and Harnett
Counties) and R-2204A (NC 11 in Duplin County). Tables 16 and 17 update the R-
2562AA/AB compensatory wetland mitigation requirements authorized in the project's
CWA §§404/401 permits. Table 16 summarizes the compensatory wetland mitigation
proposal for R-2562AA/AB. Table 17 outlines the accumulative compensatory wetland
mitigation taken from Dowd Dairy Farm Mitigation Site. Revised mitigation debit ledger
maps and x-y coordinates of Dowd Dairy Farm Mitigation Site are also included as an
attachment to this permit modification application letter.

Stream Mitigation
According to Table D, the project impacts 1,470 linear ft (448 m) of existing stream
channel and relocates 476 linear ft (145 m) of stream channel. Per the project's CWA
§§404/401 permits, the 476 linear ft of relocated channels count toward 1:1 on-site stream
mitigation. After subtracting out the project's revised on-site site stream mitigation
credits, the entire project will result in 994 linear ft (303 m) of stream channel loss (i. e.,
1,470 linear ft existing stream channel impacted - 476 linear ft relocated stream channel
as on-site stream mitigation = 994 linear ft stream channel loss). In order to offset the
stream loss, NCDOT proposes to mitigate for 1,988 linear ft (606 m) of streams under its
2:1 off-site compensatory stream mitigation requirements.
The project's CWA permits authorize compensatory off-site stream mitigation for 1,660
linear ft (506 m). Per a letter dated June 12, 2000, NC Wetlands Restoration Program
(NCWRP) received check number.1016493 in the amount of $207,500 as payment for the
compensatory off-site stream mitigation requirements authorized under the project's
CWA §§404/401 permits. As specified under the project's CWA permits, NCWRP will
restore 1,660 linear ft (506 m) of jurisdictional stream in Cataloging Unit 0303004 of the
Cape Fear River Basin.
The NCDOT lost 164 linear ft (50 m) of permitted on-site stream mitigation because of
the additional 1500 mm reinforced concrete pipe proposed for Site 10's jurisdictional
stream along the AA section of the project. Therefore, NCDOT proposes to compensate
for the lost on-site stream mitigation through an additional 328 linear ft (100 m) off-site
stream mitigation at a 2:1 ratio. The additional 328 linear ft of off-site stream mitigation
plus the permitted 1,660 ft of off-site stream mitigation provided by NCWRP comprise
the project's revised off-site stream mitigation figure of 1,988 linear ft now required for
R-2562AA/AB. In a letter dated September 6, 2000, NCDOT requested from NCWRP
an additional 328 linear ft of off-site stream mitigation to compensate for the lost on-site
stream mitigation. At a cost of $125 per stream mitigation unit, NCDOT proposes to pay
NCWRP an additional $41,000 for compensatory stream mitigation.
17
Authorization Request
In summary, construction of the proposed NC 87 widening will permanently impact
11.154 ac (4.514 ha) and temporarily impact 0.743 ac (0.301 ha) of jurisdictional
wetlands, fill 0.619 ac (0.251 ha) of surface waters (i.e., ponds), impact 1,470 linear ft
(448 m) of existing stream channel, and relocate 476 linear ft (145 m) of stream channel.
Per the project's CWA §§404/401 permits, the 476 linear ft of relocated channels count
toward on-site stream mitigation. Consequently, the entire project will result in 994
linear ft (303 m) of stream channel loss. In order to offset jurisdictional wetland impacts,
NCDOT proposes to provide 5.8 (2.3) of restored riverine wetlands and 16.4 ac (6.6 ha)
of restored non-riverine wetlands from Dowd Dairy Farm Mitigation Site. In order to
compensate for 164 linear ft (50 m) of lost on-site stream mitigation, NCDOT also
proposes to pay NCWRP an additional $41,000 for compensatory off-site stream
mitigation.
Based upon the revised impacts to jurisdictional wetlands and streams and revised
compensatory wetland and stream mitigation, NCDOT requests authorization to modify
the project's CWA §404 IP of March 7, 2000 and CWA §401 Water Quality Certification
of February 22, 2000 in order to continue constructing the project. Enclosed are revised
permit drawings and wetland mitigation debit ledger maps that depict the project's
updated wetland and stream impacts and compensatory wetland mitigation requirements.
A $475 check addressed to NCDWQ is also enclosed for application to a CWA §401
Water Quality Certification modification. If you have any questions or need additional
information, please call Mr. Tim Bassette at [phone] 005.

DAVID MCCOY
SECRETARY
Attention: Mr. Dave Timpy 001237
NCDOT Project Coordinator
Subject: NC 87, from I-95 to NC 20, Bladen and Cumberland Counties, State
Project No. 6.439001T, TIP No. R-2562AA/AB; USACE Action
ID 199304806; DQC Project No. 990340.
Dear Sir:
This North Carolina Department of Transportation (NCDOT) apOication proposes to
modify the March 7, 2000 Clean Water Act (CWA) &404 IP and February 22, 2000
CWA 6401 Water Oualitv Certification for TIP No. R-2562AA/AB (NC 87). The entire
R-2562 project consists of widening and improving NC 87 from its existing two-lane
section to a four-lane divided section with a 46-ft (14-m) wide grass median. The 28 mi
(45 km) long project begins east of I-95 in Cumberland County and ends at the
NC 87/Elizabethtown Bypass in Bladen County.
Project Breakdown and Construction Schedule
For construction purposes, NCDOT divides the R-2562 project into five sections: AA,
AB, B, C, and D. The NCDOT completed construction on the B section of R-2562 in
December 1999. The project impacted 0.30 ac (0.12 ha) of wetlands and was authorized
under CWA §404 Nationwide Permit No. 26 (US Army Corps of Engineers Action ID
199704613, NC Division of Water Quality Project No. 97101). The NCDOT began
constructing the AA and AB sections of the project in April 2000. The Project
Breakdown Map for R-2562, located at the end of this permit application modification
letter, illustrates each section of the project. Table 1 contains information concerning the
construction schedule, length, and termini of each section.

Project History for R-2562AA/AB
On April 14, 1999, NCDOT submitted a CWA §404 permit application to the US Army
Corps of Engineers (USACE) for an Individual Permit (IP) and the NC Division of Water
Quality (NCDWQ) for a CWA §401 Water Quality Certification. The April 14, 1999
permit application was placed on Public Notice on June 3, 1999. In a letter dated August
13, 1999, NCDWQ placed the April 14, 1999 permit application on hold. On February
17, 2000, NCDOT submitted a revised IP application that updated the initial April 1999
permit application. The NCDOT was authorized to construct the AA and AB sections of
R-2562 by a CWA §404 IP (Permit No. 199304806) from the USACE and a CWA §401
Water Quality Certification No. 3268 (Project No. 990340) from the NCDWQ. The
permit and water quality certification authorized NCDOT to drain, excavate, clear, or
discharge fill material into 13.508 ac (5.466 ha) of jurisdictional wetlands. The project's
permits also authorize NCDOT to discharge fill into 1,467 linear ft (447 m) of
jurisdictional stream associated with the Cape Fear River and its tributaries.
Environmental Agency Field Review
In order to complete the project's final wetland/stream design files and resolve the
project's drainage impacts, NCDOT natural system specialists Mr. Tim Bassette, Mr.
Jared Gray, and Mr. Chris Murray conducted a wetland delineation and drainage impact
field review along several sites of R-2562AA. The project's biological fieldwork was
completed March 13-15, 2000. On March 29, 2000, Mr. Bassette held an environmental
field review with Mr. Dave Timpy, USACE, in order to verify new wetland delineation
boundaries and resolve the project's drainage impacts that were computed by the ellipse
equation. Mr. John Hennessy, NCDWQ, declined to participate in the field review.
Following the review, Mr. Timpy contacted Mr. Hennessy by phone in order to verify the
resolved drainage impact issues. Mr. Hennessy concurred with Mr. Timpy's findings in
the field.
The USACE reviewed Sites 2, 8, 9, and 10 during the March 29, 2000 field review.
Drainage impacts originally computed by the ellipse equation were reviewed on Sites 2
and 8. The USACE verified newly delineated wetland boundaries on Sites 8 - 10.
Modeled wetland drainage impacts were eliminated at Sites 2 and 8 for the following four
reasons:
• The USACE does not consider the drainage impacts at the sites to be significant due
to the small size of the streams associated with each site's wetland.
• The existing and proposed invert elevations are nearly the same for each site. A -
0.033 ft (-0.010 m) change in invert elevation is proposed for the pipe outlet at Station
2
No. 27+75 left of -LRev- (Site 2). The NCDOT proposes a +0.755 ft (+0.230 m)
change in invert elevation at Station 42+20 right of -LRev- (Site 8).
• The ellipse equation failed to correctly model the existing drainage conditions at both
sites.
• The USACE felt that the project's remaining proposed drainage impacts modeled by
the ellipse equation represents a highly conservative estimate of such impacts.
Consequently, the agency felt that the project's remaining drainage impacts will more
than make up for the insignificant amount of wetland drainage impacts that will
actually occur at Sites 2 and 8.
Revised Jurisdictional Impacts to Waters of the United States (Wetlands/Surface Waters)
Wetlands
Wetland construction impacts for the R-2562AA/AB widening project were revised by
NCDOT after the environmental agencies authorized the project's CWA permits. The
AA and AB sections of R-2562 will now permanently impact 11.154 ac (4.514 ha) and
temporarily impact 0.743 ac (0.301 ha) of jurisdictional wetlands. Sections AA and AB
will together fill 6.444 ac (2.608 ha), excavate 0.956 ac (0.387 ha), drain 3.534 ac (1.430
ha), permanently clear ac 0.220 ac (0.089 ha), and temporarily clear 0.743 ac (0.301 ha)
of jurisdictional wetlands. The AA Section will permanently impact 8.881 ac (3.594 ha)
and temporarily impact 0.395 ac (0.160 ha) of jurisdictional wetlands. Jurisdictional
wetland impacts along the AB section of R-2562 remain the same as the originally
permitted impacts. Of the 11.154 ac of permanently impacted wetlands on the AA and
AB sections, 2.891 ac (1.170 ha) are considered riverine impacts, with the remaining
8.263 ac (3.344 ha) considered non-riverine impacts.
Table 2 depicts the revised jurisdictional wetland impacts for the AA and AB sections of
R-2562. Table 3 illustrates the revised jurisdictional wetland impacts for just the AA
section of the project. Permitted wetland impact areas originate from the project's CWA
§404 IP of March 7, 2000 and CWA §401 Water Quality Certification of February 22,
2000. The tables' shaded boxes represent revisions to the permitted wetland impacts
under a particular impact activity.

Tables A and B, located at the end of this permit modification application cover letter,
summarize the project's revised permanent and temporary jurisdictional wetland impacts
on a site-by-site and basis. These tables include information pertinent to each wetland
site, including station number, wetland type, riverine or non-riverine association,
NCDWQ rating (4' Version), Cowardin classification, and acreage impacts via fill,
excavation, drainage, permanent clearing, and temporary clearing. Table C, also located
at the end of this application cover letter, depicts the project's revised permanent and
temporary jurisdictional wetland impacts by community type.
According to page 4 of the revised February 17, 2000 IP application, NCDOT will utilize
Method II Mechanized Clearing for the entire project. Consequently, wetland vegetation
will only be cleared, rather than cleared and grubbed, on the project. With one exception,
all cleared wetland areas count toward temporary wetland impacts. The exception
pertains to cleared wetland areas that intersect drained wetland areas. Under this
scenario, all cleared wetland impact areas are considered permanently cleared wetland
impacts, and are depicted as such in the enclosed revised wetland/surface water impact
summary sheet (permit drawing 11 of 24, dated 5/22/00) and Tables A and C.
Site by Site Description of Revised Jurisdictional Wetland Impacts
Information is provided below on a newly proposed temporary work bridge across Site 1
of the AA section. Information is also provided for those sites (i.e., Sites 2 - 3 and 6 -
10) with revised wetland impacts. Tables 4 -10 summarize the revised jurisdictional
wetland impacts on a site by site basis. Permitted wetland impact areas originate from
the project's CWA §404 IP of March 7, 2000 and CWA §401 Water Quality Certification
of February 22, 2000. The tables' shaded boxes represent revised wetland impacts under
a particular impact activity.
Site 1 wetlands, AA Section (see enclosed permit drawings 12A and 12B of 24, dated 7/25/00)
In order to construct the permanent dual bridges over Rockfish Creek, NCDOT proposes
to construct, via top-down construction, a temporary work bridge across the stream. The
temporary work bridge will be constructed between the existing bridge and the new
southbound permanent bridge. The NCDOT will use the temporary work bridge for
4
equipment crossing during low water and/or construction activities. Construction of the
temporary work bridge will begin along the south bank of Rockfish Creek, and continue
northward until it joins the top of the stream's north bank. Once both permanent bridges
are completed, NCDOT will remove the temporary work bridge.
The temporary work bridge consists of a trestle type pier of steel H pilings capped with
appropriate strength material. The bridge will contain six bents that will be driven into
the substrate. A vibratory hammer will be used to pull out the piles when the temporary
bridge is removed. No earthen materials will be permitted into waters of the United
States. If NCDOT foresees earthen materials entering waters of the United States, as
defined under 33 CFR §328.3(a), steel sheet pilings will be installed on the upland area
abutments in order to prevent such an action from taking place.
The temporary work bridge consists of six bents. The first three bents (i.e., Bents 1- 3)
are proposed to be constructed in Rockfish Creek. Bent 4 will be constructed along the
south bank of Rockfish Creek along an upland area and the stream's edge. Bent 5 will be
constructed in the jurisdictional riverine wetland located at Site 1 of the AA section.
Bent 6 will be constructed in an upland area along creek's south bank.
Piles along Bent 5 of the temporary work bridge will temporarily impact jurisdictional
riverine wetlands at Site 1 (see permit drawing 12 of 24; June 1997). These temporary
wetland impacts occur when the piles are driven into the wetlands below. Once the piles
are removed, the temporarily impacted wetlands are expected to naturally revegetate.
The project's CWA permits already authorize a portion of Site 1's wetlands to be cleared
and, consequently, counted as a temporary wetland impact. The piles along Bent 5 of the
temporary work bridge occur in the same wetland area that was permitted to be cleared.
Consequently, NCDOT expects no additional permanent or temporary jurisdictional
wetland impacts to occur at Site 1 of the AA section beyond what is already authorized
under the project's CWA permits. See enclosed permit drawings 12A and 12B of 24
(dated 7/25/00) for a plan view, cross-section view, and bent-end view of the proposed
temporary work bridge.
Site 2 wetlands, AA Section (see enclosed revised permit drawing 13 of 24, dated 5/22/00)
Site 2's fill, excavation, temporary clearing, and total permanent wetland impacts
increased from the project's authorized permits. Wetland drainage impacts decreased as
compared to the same permits. Table 4 depicts the new wetland impacts. A discussion of
the impact changes follows the table.

Fill Project design and depicted wetland fill area/limits did not change from Site 2's
permit drawing submitted with the February 17, 2000 CWA §§404/401 revised IP
application. The revised IP application contains an incorrectly calculated wetland fill
impact for Site 2. The enclosed revised wetland/surface water impact summary sheet
(permit drawing 11 of 24, dated 5/22/00) and Tables 4 and A correctly depict the new fill
impact.
Excavation - Project design and depicted wetland excavation area/limits did not change
from Site 2's permit drawing submitted with the February 17, 2000 CWA §§404/401 IP

excavation impact for Site 2. Tables 4 and A and the enclosed revised wetland/surface
water impact summary sheet (permit drawing 11 of 24, dated 5/22/00) correctly depict the
new excavation impact.
Drainage - The site's originally modeled drainage impact was eliminated by USACE for
the reasons outlined in the "Environmental Agency Field Review" section of this permit
modification application letter. Enclosed revised permit drawing 13 of 24 (dated
5/22/00), revised wetland/surface water impact summary sheet (permit drawing 11 of 24,

Site 2.
Temporary clearing - Project design and depicted wetland clearing area/limits did not
change from Site 2's permit drawing submitted with the February 17, 2000 CWA
§§404/401 IP application. The revised IP application contains an incorrectly calculated
temporary wetland clearing impact for Site 2. Tables 4 and A and the enclosed revised

Excavation- Permit drawing 13 of 24 (dated 2/17/00) associated with the project's CWA
§§404/401 permits incorrectly depict a portion of the wetland excavation impact as
occurring in the pond to be drained. This error was eliminated on the enclosed revised

Fill - Project design and depicted wetland fill area/limits changed from Site 8's permit
drawing (permit drawing 19 of 24, dated 2/17/00) associated with the project's CWA
§§404/401 permits. The NCDOT utilized an incorrect wetland boundary file in its
February 17, 2000 revised IP application. Furthermore, a portion of the wetland was re-
delineated on March 13-15, 2000 by NCDOT and subsequently verified by USACE.
Enclosed revised permit drawing 19 of 24 (dated 5115100), revised wetland/surface water
impact summary sheet (permit drawing 11 of 24, dated 5/22/00), and Tables 8 and A
correctly depict the new wetland fill impacts at Site 8.
Drainage - The site's originally modeled and permitted drainage impact was eliminated
by USACE for the reasons outlined in the "Environmental Agency Field Review" section
of this permit modification application letter. Enclosed revised permit drawing 19 of 24
(dated 5115100), revised wetland/surface water impact summary sheet (permit drawing 11
of 24, dated 5/22/00), and Tables 8 and A correctly depict the new wetland fill impacts at
Site 8.
Permanent and temporary clearing - All permanent clearing wetland impacts that
intersected the site's permitted drainage impacts are now counted as temporary clearing
impacts because USACE eliminated the site's drainage impacts. Tables 8 and A and the
enclosed revised wetland/surface water impact summary sheet (permit drawing 11 of 24,
dated 5/22/00) correctly depict the new permanent and temporary wetland clearing
impacts.

Drainage - Wetland drainage impacts calculated from the ellipse equation initially
extended beyond the originally delineated wetland boundaries. During the project's
March 13-15, 2000 wetland delineations, Site 9's wetland boundaries were extended out
past the drainage impact "circle" calculated by the ellipse equation. This drainage impact
"circle" was then extended to encompass the additional wetlands at the site. Enclosed
revised permit drawing 20A of 24 (dated 5115100), revised wetland/surface water impact
summary sheet (permit drawing 11 of 24, dated 5/22/00), and Tables 9 and A correctly

Permanent clearing - Project design and depicted wetland clearing area/limits did not
change from Site 9's permit drawing (permit drawing 20 of 24, dated 2/17/00) associated
with the project's CWA §§404/401 permits. The February 17, 2000 revised IP
application contains an incorrectly calculated permanent wetland clearing impact for Site
9. Tables 9 and A and the enclosed revised wetland/surface water impact summary sheet
(permit drawing 11 of 24, dated 5/22/00) correctly depict the new permanent wetland
clearing impact.
Site 10 wetlands, AA Section (see enclosed revised permit drawing 20B of 24, dated 5/22/00)
Site 10's fill, excavation, drainage, permanent clearing, and total permanent wetland

Fill - The NCDOT utilized an incorrect wetland boundary file in its February 17, 2000
revised IP application. This specifically affects the site's eastern jurisdictional wetland
boundary. Furthermore, the February 17, 2000 revised IP application contains an
incorrectly depicted wetland fill area along the western portion of the site's fill limits.
Enclosed revised permit drawing 20B of 24 (dated 5115100), revised wetland/surface
water impact summary sheet (permit drawing 11 of 24 dated 5/22/00), and Tables 10 and
A correctly depict the new wetland fill impacts at Site 10.
Excavation and drainage - Site 10's wetland boundaries were re-delineated by NCDOT
on March 13-15, 2000 and subsequently verified by USAGE. In order to eliminate the
site's wetland drainage impacts depicted on the project's CWA §§404/401 permits,
NCDOT Hydraulics Unit eliminated the proposed jurisdictional stream relocation through
the site's wetlands. This subsequently eliminated the site's wetland excavation impacts.
Enclosed revised permit drawing 20B of 24 (dated 5115100), revised wetland/surface
water impact summary sheet (permit drawing 11 of 24, dated 5/22/00), and Tables 10 and
A correctly depict the new wetland fill impacts at Site 10.
Permanent and temporary clearing - All clearing impacts depicted on this site's permit
drawing (permit drawing 20 of 24, dated 2/17/00) associated with the project's CWA
§§404/401 permits were considered permanent wetland impacts because the site's
drainage impacts intersected the clearing impacts. Since the wetland drainage impacts at
Site 10 were eliminated, all permanent clearing impacts no longer insect the drainage
impacts and are, therefore, considered temporary clearing impacts. The site's total
wetland clearing impacts (i.e., permanent + temporary clearing) have decreased from the
project's CWA permits because the site's proposed relocated stream channel was
eliminated. Additional clearing impacts were incorporated around this proposed channel.
Enclosed revised permit drawing 20B of 24 (dated 5/15/00), revised wetland/surface
water impact summary sheet (permit drawing 11 of 24, dated 5/22/00), and Tables 10 and
A correctly depict the new permanent and temporary wetland clearing impacts at Site 10.

Surface Waters
After the environmental agencies authorized the environmental permits for R-
2562AA/AB, NCDOT revised the surface water construction impacts on the widening
project: The AA and AB sections of R-2562 will together fill 0.619 ac (0.251 ha) of
surface waters (i.e., ponds), impact 1,470 linear ft (448 m) of existing stream channel, and
relocate 476 linear ft (145 m) of stream channel. Per the project's CWA §§404/401
permits, the 476 linear ft of relocated channels count toward on-site stream mitigation.
Consequently; the entire project will result in 994 linear ft (303 m) of stream channel
loss. The AA section of R-2562A will fill 0.321 ac (0.130 ha) of surface waters (i.e.,
ponds), impact 1,079 linear ft (329 m) of existing stream channel, and relocate 476 linear
ft (145 m) of stream channel. Per the project's CWA §§404/401 permits, the 476 linear ft
of relocated channels count toward on-site stream mitigation. Consequently, the AA
section will result in 603 linear ft (184 m) of stream channel loss. The AB section's fill
in surface waters (i. e., ponds), impacted existing stream channel (listed as "stream
channel loss" in Table 5 of the project's April 14, 1999 CWA §§404/401 IP application),
and relocated stream channel equate to the area and linear distances authorized under the
project's CWA §§404/401 permits for that section of R-2562.
Table 11 depicts the revised jurisdictional surface water impacts for the AA and AB
sections of R-2562. Table 12 illustrates the revised jurisdictional surface water impacts
for just the AA section of the project. Permitted surface water impact area and linear
distances originate from the project's CWA §404 IP of March 7, 2000 and CWA §401
Water Quality, Certification of February 22, 2000. The tables' shaded boxes represent

station number, fill in surface water (i.e., ponds), existing stream channel impacted,
relocated stream channel, proposed 1:1 compensatory on-site stream mitigation, stream
channel loss, and proposed 2:1 compensatory off-site stream mitigation.
Site by Site Description of Revised Surface Water Impacts
Tables 13 -15 summarize the revised jurisdictional surface water impacts on a site by
site basis. Information is provided only for those sites (i.e., Sites 3, 9, and 10) with
revised surface water impacts. Permitted surface water impact area and linear distances
originate from the project's CWA §404 IP of March 7, 2000 and CWA §401 Water
Quality Certification of February 22, 2000. The tables' shaded boxes represent revised
surface water impacts for a particular impact activity.
Site 3 surface waters, AA section (see enclosed revised permit drawing 13 of 24, dated 5/22/00)
The NCDOT is relocating an unnamed jurisdictional stream through an existing pond at
Site 3. The project's CWA §§404/401 permits authorize the fill of 0.158 ac (0.064 ha) of
the site's pond. Since the relocated jurisdictional stream will drain the remaining portion
of the pond not authorized to be filled, NCDOT Hydraulics Unit counted the entire pond
area as a fill in surface water impact. Enclosed revised permit drawing 13 of 24 (dated
5/22/00) illustrates the drained pond. The enclosed revised wetland/surface water impact
summary sheet (permit drawing 11 of 24, dated 5/22/00), and Tables 13 and D correctly

The linear distance of existing channel impacted has not changed from the project's
original CWA §§404/401 permits. Existing channel impact of 13 linear ft (4 m) wasn't
included as part of Site 9's channel impacts on the project's April 14, 1999 permit
application and subsequently issued permits. This total was, however, accounted for in
the initial permit application and permits under the amount of required compensatory off-
site stream mitigation. An additional 13 linear ft of stream channel impacts at Site 9
appear in Tables 14 and D solely for accounting purposes.

Site 10 surface waters, AA Section (see enclosed revised permit drawing 20B of 24, dated 5/22/00)
Site 10 is an unnamed stream associated with Murphy Swamp. In order to reduce this
site's initially proposed 1.666 ac (0.674 ha) of wetland drainage impacts, NCDOT
Hydraulics Unit eliminated the relocated channel that drained the site's wetlands. A 1500
mm reinforced concrete pipe measuring 131 ft (40 m) in length will now convey water
along Site 10's jurisdictional stream, instead of the initially permitted 164 linear ft (50 m)
of relocated stream channel. The project's CWA §§404/401 permits counted the initially
proposed 164 linear ft of relocated stream channel as compensatory on-site stream
mitigation. The NCDOT proposes to compensate for the lost 164 linear ft of on-site
stream mitigation through an additional 328 linear ft (100 m) off-site stream mitigation at
a 2:1 ratio. Enclosed revised permit drawing 20B of 24 (dated 5/22/00) illustrates the
14
revised hydraulic conveyance at Site 10. The enclosed revised wetland/surface water
impact summary sheet (permit drawing 11 of 24, dated 5/22/00) and Tables 15 and D

Compensatory Wetland/Stream Mitigation
Wetland Mitigation
The NCDOT Project Development and Environmental Analysis Branch proposes to
revise the project's permitted compensatory wetland mitigation from Dowd Dairy Farm
Mitigation Site. The mitigation site is located in north central Bladen County,
approximately 7 miles (11 km) north of Elizabethtown and 2 miles (3 km) east of White
Oak. State Route (SR) 1324 (Dowd Dairy Farm Road) borders the site to the north, SR
1332 (Oak Grove Church Road) lies to the west, and dense forest is situated south and
east of the site. The site, which sits along a Coastal Plain interstream divide between
Ellis Creek to the west and Palmer Branch to the east, falls within the Cape Fear River
subbasin 03-06-16 and Hydrologic. Unit #03030005. The wetland and surface water
impacts associated with R-2562AA/AB fall within the Cape Fear River subbasins 03-06-
15 and 03-06-16 and Hydrologic Unit #03030004 and #03030005.
Dowd Dairy Farm Mitigation Site consists of approximately 638 ac (258 ha) of prior-
converted (PC) cropland and approximately 20 ac (8 ha) of cropland on non-hydric soils.
Prior-converted cropland is a wetland that was manipulated and cropped prior to 23
December 1985 to the extent that it no longer exhibits important wetland functions.
Prior-converted croplands do not fall under the regulatory jurisdiction of CWA §404.
Compensatory wetland mitigation credits for the Dowd Dairy Farm Mitigation Site are
based on wetland functions generated by restoration and comparison of restored functions
to impacted wetland resources. A base-line estimated mitigation plan for the site includes
13 ac (5 ha) of restored riverine (headwater) wetlands, 518 ac (210 ha) of restored non-
riverine wetlands, 20 ac (8 ha) of restored wetland/upland ecotones, and 107 ac (43 ha) of
restored wetland buffers that are adjacent to perimeter canals. The NCDOT's Wetland
Mitigation Plan: Dowd Dairy Farm Wetlands, Bladen County, North Carolina (May
1997) contains further information on this mitigation site.
15
Site construction for Dowd Dairy Mitigation Site is divided into two parts, Phase I and
Phase II. Phase I consisted of clearing/grubbing/ripping most of the site, filling lateral
ditches, and adding ditch plugs. The NCDOT completed construction activities under
Phase I in September 1998. Planting for the first phase was completed in March 1999.
All monitoring wells were installed during Phase I. The NCDOT is conducting on-going
hydrologic monitoring at the mitigation site. Activities conducted under the second phase
of construction will include filling the central channel and installing related ditch plugs.
Phase II construction activities began during the summer of 1999, were halted for an
extended period of time due to wetness from several hurricanes, and will be completed by
the summer of 2000. The final planting for Phase II will be completed by March 2001.
In order to offset 11.154 ac (4.514) ha of permanent wetland impacts associated with the
project, NCDOT proposes to debit 5.8 ac (2.3 ha) of restored riverine wetlands and 16.4
ac (6.6 ha) of restored non-riverine wetlands from Dowd Dairy Farm Mitigation Site.
This project is one of three NCDOT projects that use a portion of Dowd Dairy Farm
Mitigation Site for compensatory wetland mitigation. The other two NCDOT projects
that utilize the mitigation site are R-2238AA/ABBA (NC 87 in Cumberland and Harnett
Counties) and R-2204A (NC 11 in Duplin County). Tables 16 and 17 update the R-
2562AA/AB compensatory wetland mitigation requirements authorized in the project's
CWA §§404/401 permits. Table 16 summarizes the compensatory wetland mitigation
proposal for R-2562AA/AB. Table 17 outlines the accumulative compensatory wetland
mitigation taken from Dowd Dairy Farm Mitigation Site. Revised mitigation debit ledger
maps and x-y coordinates of Dowd Dairy Farm Mitigation Site are also included as an
attachment to this permit modification application letter.

Stream Mitigation
According to Table D, the project impacts 1,470 linear ft (448 m) of existing stream
channel and relocates 476 linear ft (145 m) of stream channel. Per the project's CWA
§§404/401 permits, the 476 linear ft of relocated channels count toward 1:1 on-site stream
mitigation. After subtracting out the project's revised on-site site stream mitigation
credits, the entire project will result in 994 linear ft (303 m) of stream channel loss (i.e.,
1,470 linear ft existing stream channel impacted - 476 linear ft relocated stream channel
as on-site stream mitigation = 994 linear ft stream channel loss). In order to offset the
stream loss, NCDOT proposes to mitigate for 1,988 linear ft (606 m) of streams under its
2:1 off-site compensatory stream mitigation requirements.
The project's CWA permits authorize compensatory off-site stream mitigation for 1,660
linear ft (506 m). Per a letter dated June 12, 2000, NC Wetlands Restoration Program
(NCWRP) received check number.1016493. in the amount of $207,500 as payment for the
compensatory off-site stream mitigation requirements authorized under the project's
CWA §§404/401 permits. As specified under the project's CWA permits, NCWRP will
restore 1,660 linear ft (506 m) of jurisdictional stream in Cataloging Unit 0303004 of the
Cape Fear River Basin.
The NCDOT lost 164 linear ft (50 m) of permitted on-site stream mitigation because of
the additional 1500 mm reinforced concrete pipe proposed for Site 10's jurisdictional
stream along the AA section of the project. Therefore, NCDOT proposes to compensate
for the lost on-site stream mitigation through an additional 328 linear ft (100 m) off-site
stream mitigation at a 2:1 ratio. The additional 328 linear ft of off-site stream mitigation
plus the permitted 1,660 ft of off-site stream mitigation provided by NCWRP comprise
the project's revised off-site stream mitigation figure of 1,988 linear ft now required for
R-2562AA/AB. In a letter dated September 6, 2000, NCDOT requested from NCWRP
an additional 328 linear ft of off-site stream mitigation to compensate for the lost on-site
stream mitigation. At a cost of $125 per stream mitigation unit, NCDOT proposes to pay
NCWRP an additional $41,000 for compensatory stream mitigation.
17
Authorization Request
In summary, construction of the proposed NC 87 widening will permanently impact
11.154 ac (4.514 ha) and temporarily impact 0.743 ac (0.301 ha) of jurisdictional
wetlands, fill 0.619 ac (0.251 ha) of surface waters (i.e., ponds), impact 1,470 linear ft
(448 m) of existing stream channel, and relocate 476 linear ft (145 m) of stream channel.
Per the project's CWA §§404/401 permits, the 476 linear ft of relocated channels count
toward on-site stream mitigation. Consequently, the entire project will result in 994
linear ft (303 m) of stream channel loss. In order to offset jurisdictional wetland impacts,
NCDOT proposes to provide 5.8 (2.3) of restored riverine wetlands and 16.4 ac (6.6 ha)
of restored non-riverine wetlands from Dowd Dairy Farm Mitigation Site. In order to
compensate for 164 linear ft (50 m) of lost on-site stream mitigation, NCDOT also
proposes to pay NCWRP an additional $41,000 for compensatory off-site stream
mitigation.
Based.upon the revised impacts to jurisdictional wetlands and streams and revised
compensatory wetland and stream mitigation, NCDOT requests authorization to modify
the project's CWA §404 IP of March 7, 2000 and CWA §401 Water Quality Certification
of February 22, 2000 in order to continue constructing the project. Enclosed are revised
permit drawings and wetland mitigation debit ledger maps that depict the project's
updated wetland and stream impacts and compensatory wetland mitigation requirements.
A $475 check addressed to NCDWQ is also enclosed for application to a CWA §401
Water Quality Certification modification. If you have any questions or need additional
information, please call Mr. Tim Bassette at [phone] x305.

Project No. 6.439001 T, TIP No. R-2562AA/AB; USACE Action
ID 199304806; DQC Project No. 990340.
Dear Sir:
This North Carolina Department of Transportation (NCDOT) awlication_proposes to
modify the March 7, 2000 Clean Water Act (CWA) §404 IP and February 22, 2000
CWA 6401 Water Oualitv Certification for TIP No. R-2562AA/AB (NC 87). The entire
R-2562 project consists of widening and improving NC 87 from its existing two-lane
section to a four-lane divided section with a 46-ft (14-m) wide grass median. The 28 mi
(45 km) long project begins east of I-95 in Cumberland County and ends at the
NC 87/Elizabethtown Bypass in Bladen County.
Project Breakdown and Construction Schedule
For construction purposes, NCDOT divides the R-2562 project into five sections: AA,
AB, B, C, and D. The NCDOT completed construction on the B section of R-2562 in
December 1999. The project impacted 0.30 ac (0.12 ha) of wetlands and was authorized
under CWA §404 Nationwide Permit No. 26 (US Army Corps of Engineers Action ID
199704613, NC Division of Water Quality Project No. 97101). The NCDOT began
constructing the AA and AB sections of the project in April 2000. The Project
Breakdown Map for R-2562, located at the end of this permit application modification
letter, illustrates each section of the project. Table 1 contains information concerning the
construction schedule, length, and termini of each section.

Project History for R-2562AA/AB
On April 14, 1999, NCDOT submitted a CWA §404 permit application to the US Army
Corps of Engineers (USACE) for an Individual Permit (IP) and the NC Division of Water
Quality (NCDWQ) for a CWA §401 Water Quality Certification. The April 14, 1999
permit application was placed on Public Notice on June 3, 1999. In a letter dated August
13, 1999, NCDWQ placed the April 14, 1999 permit application on hold. On February
17, 2000, NCDOT submitted a revised IP application that updated the initial April 1999
permit application. The NCDOT was authorized to construct the AA and AB sections of
R-2562 by a CWA §404 IP (Permit No. 199304806) from the USACE and a CWA §401
Water Quality Certification No. 3268 (Project No. 990340) from the NCDWQ. The
permit and water quality certification authorized NCDOT to drain, excavate, clear, or
discharge fill material into 13.508 ac (5.466 ha) of jurisdictional wetlands. The project's
permits also authorize NCDOT to discharge fill into 1,467 linear ft (447 m) of
jurisdictional stream associated with the Cape Fear River and its tributaries.
Environmental Agency Field Review
In order to complete the project's final wetland/stream design files and resolve the
project's drainage impacts, NCDOT natural system specialists Mr. Tim Bassette, Mr.
Jared Gray, and Mr. Chris Murray conducted a wetland delineation and drainage impact
field review along several sites of R-2562AA. The project's biological fieldwork was
completed March 13-15, 2000. On March 29, 2000, Mr. Bassette held an environmental
field review with Mr. Dave Timpy, USACE, in order to verify new wetland delineation
boundaries and resolve the project's drainage impacts that were computed by the ellipse
equation. Mr. John Hennessy, NCDWQ, declined to participate in the field review.
Following the review, Mr. Timpy contacted Mr. Hennessy by phone in order to verify the
resolved drainage impact issues. Mr. Hennessy concurred with Mr. Timpy's findings in
the field.
The USACE reviewed Sites 2, 8, 9, and 10 during the March 29, 2000 field review.
Drainage impacts originally computed by the ellipse equation were reviewed on Sites 2
and 8. The USACE verified newly delineated wetland boundaries on Sites 8 - 10.
Modeled wetland drainage impacts were eliminated at Sites 2 and 8 for the following four
reasons:
• The USACE does not consider the drainage impacts at the sites to be significant due
to the small size of the streams associated with each site's wetland.
• The existing and proposed invert elevations are nearly the same for each site. A -
0.033 ft (4010 m) change in invert elevation is proposed for the pipe outlet at Station
2
No. 27+75 left of -LRev- (Site 2). The NCDOT proposes a +0.755 ft (+0.230 m)
change in invert elevation at Station 42+20 right of -LRev- (Site 8).
The ellipse equation failed to correctly model the existing drainage conditions at both
sites.
The USACE felt that the project's remaining proposed drainage impacts modeled by
the ellipse equation represents a highly conservative estimate of such impacts.
Consequently, the agency felt that the project's remaining drainage impacts will more
than make up for the insignificant amount of wetland drainage impacts that will
actually occur at Sites 2 and 8.
Revised Jurisdictional Impacts to Waters of the United States (Wetlands/Surface Waters)
Wetlands
Wetland construction impacts for the R-2562AA/AB widening project were revised by
NCDOT after the environmental agencies authorized the project's CWA permits. The
AA and AB sections of R-2562 wilt now permanently impact 11.154 ac (4.514 ha) and
temporarily impact 0.743 ac (0.301 ha) of jurisdictional wetlands. Sections AA and AB
will together fill 6.444 ac (2.608 ha), excavate 0.956 ac (0.387 ha), drain 3.534 ac (1.430
ha), permanently clear ac 0.220 ac (0.089 ha), and temporarily clear 0.743 ac (0.301 ha)
of jurisdictional wetlands. The AA Section will permanently impact 8.881 ac (3.594 ha)
and temporarily impact 0.395 ac (0.160 ha) of jurisdictional wetlands. Jurisdictional
wetland impacts along the AB section of R-2562 remain the same as the originally
permitted impacts. Of the 11.154 ac of permanently impacted wetlands on the AA and
AB sections, 2.891 ac (1.170 ha) are considered riverine impacts, with the remaining
8.263 ac (3.344 ha) considered non-riverine impacts.
Table 2 depicts the revised jurisdictional wetland impacts for the AA and AB sections of
R-2562. Table 3 illustrates the revised jurisdictional wetland impacts for just the AA
section of the project. Permitted wetland impact areas originate from the project's CWA
§404 IP of March 7, 2000 and CWA §401 Water Quality Certification of February 22,
2000. The tables' shaded boxes represent revisions to the permitted wetland impacts
under a particular impact activity.

Tables A and B, located at the end of this permit modification application cover letter,
summarize the project's revised permanent and temporary jurisdictional wetland impacts
on a site-by-site and basis. These tables include information pertinent to each wetland
site, including station number, wetland type, riverine or non-riverine association,
NCDWQ rating (4' Version), Cowardin classification, and acreage impacts via fill,
excavation, drainage, permanent clearing, and temporary clearing. Table C, also located
at the end of this application cover letter, depicts the project's revised permanent and
temporary jurisdictional wetland impacts by community type.
According to page 4 of the revised February 17, 2000 IP application, NCDOT will utilize
Method II Mechanized Clearing for the entire project. Consequently, wetland vegetation
will only be cleared, rather than cleared and grubbed, on the project. With one exception,
all cleared wetland areas count toward temporary wetland impacts. The exception
pertains to cleared wetland areas that intersect drained wetland areas. Under this
scenario, all cleared wetland impact areas are considered permanently cleared wetland
impacts, and are depicted as such in the enclosed revised wetland/surface water impact
summary sheet (permit drawing 11 of 24, dated 5/22/00) and Tables A and C.
Site by Site Description of Revised Jurisdictional Wetland Impacts
Information is provided below on a newly proposed temporary work bridge across Site 1
of the AA section. Information is also provided for those sites (i. e., Sites 2 - 3 and 6 -
10) with revised wetland impacts. Tables 4 -10 summarize the revised jurisdictional
wetland impacts on a site by site basis. Permitted wetland impact areas originate from
the project's CWA §404 IP of March 7, 2000 and CWA §401 Water Quality Certification
of February 22, 2000. The tables' shaded boxes represent revised wetland impacts under
a particular impact activity.
Site 1 wetlands, AA Section (see enclosed permit drawings 12A and 12B of 24, dated 7/25/00)
In order to construct the permanent dual bridges over Rockfish Creek, NCDOT proposes
to construct, via top-down construction, a temporary work bridge across the stream. The
temporary work bridge will be constructed between the existing bridge and the new
southbound permanent bridge. The NCDOT will use the temporary work bridge for
4
equipment crossing during low water and/or construction activities. Construction of the
temporary work bridge will begin along the south bank of Rockfish Creek, and continue
northward until it joins the top of the stream's north.bank. Once both permanent bridges
are completed, NCDOT will remove the temporary work bridge.
The temporary work bridge consists of a trestle type pier of steel H pilings capped with
appropriate strength material. The bridge will contain six bents that will be driven into
the substrate. A vibratory hammer will be used to pull out the piles when the temporary
bridge is removed. No earthen materials will be permitted into waters of the United
States. If NCDOT foresees earthen materials entering waters of the United States, as
defined under 33 CFR §328.3(a), steel sheet pilings will be installed on the upland area
abutments in order to prevent such an action from taking place.
The temporary work bridge consists of six bents. The first three bents (i. e., Bents 1- 3)
are proposed to be constructed in Rockfish Creek. Bent 4 will be constructed along the
south bank of Rockfish Creek along an upland area and the stream's edge. Bent 5 will be
constructed in the jurisdictional riverine wetland located at Site 1 of the AA section.
Bent 6 will be constructed in an upland area along creek's south bank.
Piles along Bent 5 of the temporary work bridge will temporarily impact jurisdictional
riverine wetlands at Site 1 (see permit drawing 12 of 24; June 1997). These temporary
wetland impacts occur when the piles are driven into the wetlands below. Once the piles
are removed, the temporarily impacted wetlands are expected to naturally revegetate.
The project's CWA permits already authorize a portion of Site 1's wetlands to be cleared
and, consequently, counted as a temporary wetland impact. The piles along Bent 5 of the
temporary work bridge occur in the same wetland area that was permitted to be cleared.
Consequently, NCDOT expects no additional permanent or temporary jurisdictional
wetland impacts to occur at Site 1 of the AA section beyond what is already authorized
under the project's CWA permits. See enclosed permit drawings 12A and 12B of 24
(dated 7/25/00) for a plan view, cross-section view, and bent-end view of the proposed
temporary work bridge.
Site 2 wetlands, AA Section (see enclosed revised permit drawing 13 of 24, dated 5/22/00)
Site 2's fill, excavation, temporary clearing, and total permanent wetland impacts
increased from the project's authorized permits. Wetland drainage impacts decreased as
compared to the same permits. Table 4 depicts the new wetland impacts. A discussion of
the impact changes follows the table.

Fill - Project design and depicted wetland fill area/limits did not change from Site 2's
permit drawing submitted with the February 17, 2000 CWA §§404/401 revised IP
application. The revised IP application contains an incorrectly calculated wetland fill
impact for Site 2. The enclosed revised wetland/surface water impact summary sheet
(permit drawing 11 of 24, dated 5/22/00) and Tables 4 and A correctly depict the new fill
impact.
Excavation - Project design and depicted wetland excavation area/limits did not change
from Site 2's permit drawing submitted with the February 17, 2000 CWA §§404/401 IP
application. The revised IP application contains an incorrectly calculated wetland
excavation impact for Site 2. Tables 4 and A and. the enclosed revised wetland/surface
water impact summary sheet (permit drawing 11 of 24, dated 5/22/00) correctly depict the
new excavation impact.
Drainage The site's originally modeled drainage impact was eliminated by USACE for
the reasons outlined in the "Environmental Agency Field Review" section of this permit
modification application letter. Enclosed revised permit drawing 13 of 24 (dated
5/22/00), revised wetland/surface water impact summary sheet (permit drawing 11 of 24,
dated 5/22/00), and Tables 4 and A correctly depict the new wetland drainage impacts at
Site 2.
Temporary clearing - Project design and depicted wetland clearing area/limits did not
change from Site 2's permit drawing submitted with the February 17, 2000 CWA
§§404/401 IP application. The revised IP application contains an incorrectly calculated
temporary wetland clearing impact for Site 2. Tables 4 and A and the enclosed revised

Excavation - Permit drawing 13 of 24 (dated 2/17/00) associated with the project's CWA
§§404/401 permits incorrectly depict a portion of the wetland excavation impact as
occurring in the pond to be drained. This error was eliminated on the enclosed revised
permit drawing 13 of 24 (dated 5/22/00). The enclosed revised wetland/surface water
impact summary sheet (permit drawing 11 of 24, dated 5/22/00) and Tables 5 and A
correctly depict the new wetland excavation impact for Site 3.
Permanent clearing - Project design and depicted wetland clearing area/limits did not
change from Site 3's permit drawing (permit drawing 13 of 24, dated 2/17/00) associated
with the project's CWA §§404/401 permits. The February 17, 2000 revised IP
application contains an incorrectly calculated permanent wetland clearing impact for Site

Fill - Project design and depicted wetland fill area/limits changed from Site 8's permit
drawing (permit drawing 19 of 24, dated 2/17/00) associated with the project's CWA
§§404/401 permits. The NCDOT utilized an incorrect wetland boundary file in its
February 17, 2000 revised IP application. Furthermore, a portion of the wetland was re-
delineated on March 13-15, 2000 by NCDOT and subsequently verified by USACE.
Enclosed revised permit drawing 19 of 24 (dated 5/15/00), revised wetland/surface water
impact summary sheet (permit drawing 11 of 24, dated 5/22/00), and Tables 8 and A
correctly depict the new wetland fill impacts at Site 8.
Drainage - The site's originally modeled and permitted drainage impact was eliminated
by USACE for the reasons outlined in the "Environmental Agency Field Review" section
of this permit modification application letter. Enclosed revised permit drawing 19 of 24
(dated 5115100), revised wetland/surface water impact summary sheet (permit drawing 11
of 24, dated 5/22/00), and Tables 8 and A correctly depict the new wetland fill impacts at
Site 8.
Permanent and temporary clearing - All permanent clearing wetland impacts that
intersected the site's permitted drainage impacts are now counted as temporary clearing
impacts because USACE eliminated the site's drainage impacts. Tables 8 and A and the
enclosed revised wetland/surface water impact summary sheet (permit drawing 11 of 24,
dated 5/22/00) correctly depict the new permanent and temporary wetland clearing
impacts.

Site 9 wetlands, AA Section (see enclosed revised permit drawing 20A of 24,dated 5115100)
Site 9's drainage, permanent clearing, and total permanent wetland impacts increased
from the projects original CWA §§404/401 permits. Table 9 depicts the new wetland
impacts. A discussion of the wetland impact changes follows the Table 9.

Drainage - Wetland drainage impacts calculated from the ellipse equation initially
extended beyond the originally delineated wetland boundaries. During the project's
March 13-15, 2000 wetland delineations, Site 9's wetland boundaries were extended out
past the drainage impact "circle" calculated by the ellipse equation. This drainage impact
"circle" was then extended to encompass the additional wetlands at the site. Enclosed
revised permit drawing 20A of 24 (dated 5115100), revised wetland/surface water impact
summary sheet (permit drawing 11 of 24, dated 5/22/00), and Tables 9 and A correctly

Permanent clearing - Project design and depicted wetland clearing area/limits did not
change from Site 9's permit drawing (permit drawing 20 of 24, dated 2/17/00) associated
with the project's CWA §§404/401 permits. The February 17, 2000 revised IP
application contains an incorrectly calculated permanent wetland clearing impact for Site
9. Tables 9 and A and the enclosed revised wetland/surface water impact summary sheet
(permit drawing 11 of 24, dated 5/22/00) correctly depict the new permanent wetland
clearing impact.
Site 10 wetlands, AA Section (see enclosed revised permit drawing 20B of 24, dated 5/22/00)
Site 10's fill, excavation, drainage, permanent clearing, and total permanent wetland
impacts decreased from the project's original CWA §§404/401 permits. Temporary
clearing wetland impacts increased as compared to the same permits. Table 10 depicts
the new wetland impacts. A discussion of the impact changes follows the table.

Fill - The NCDOT utilized an incorrect wetland boundary file in its February 17, 2000
revised IP application. This specifically affects the site's eastern jurisdictional wetland
boundary. Furthermore, the February 17, 2000 revised IP application contains an
incorrectly depicted wetland fill area along the western portion of the site's fill limits.
Enclosed revised permit drawing 20B of 24 (dated 5115100), revised wetland/surface
water impact summary sheet (permit drawing 11 of 24 dated 5/22/00), and Tables 10 and
A correctly depict the new wetland fill impacts at Site 10.
Excavation and drainage Site 10's wetland boundaries were re-delineated by NCDOT
on March 13-15, 2000 and subsequently verified by USACE. In order to eliminate the
site's wetland drainage impacts depicted on the project's CWA §§404/401 permits,
NCDOT Hydraulics Unit eliminated the proposed jurisdictional stream relocation through
the site's wetlands. This subsequently eliminated the site's wetland excavation impacts.
Enclosed revised permit drawing 20B of 24 (dated 5115100), revised wetland/surface
water impact summary sheet (permit drawing 11 of 24, dated 5/22/00), and Tables 10 and

Permanent and temporary clearing - All clearing impacts depicted on this site's permit
drawing (permit drawing 20 of 24, dated 2/17/00) associated with the project's CWA
§§404/401 permits were considered permanent wetland impacts because the site's
drainage impacts intersected the clearing impacts. Since the wetland drainage impacts at
Site 10 were eliminated, all permanent clearing impacts no longer insect the drainage
impacts and are, therefore, considered temporary clearing impacts. The site's total
wetland clearing impacts (i.e., permanent + temporary clearing) have decreased from the
project's CWA permits because the site's proposed relocated stream channel was
eliminated. Additional clearing impacts were incorporated around this proposed channel.
Enclosed revised permit drawing 20B of 24 (dated 5115100), revised wetland/surface
water impact summary sheet (permit drawing 11 of 24, dated 5/22/00), and Tables 10 and
A correctly depict the new permanent and temporary wetland clearing impacts at Site 10.

Surface Waters
After the environmental agencies authorized the environmental permits for R-
2562AA/AB, NCDOT revised the surface water construction impacts on the widening
project. The AA and AB sections of R-2562 will together fill 0.619 ac (0.251 ha) of
surface waters (i.e., ponds), impact 1,470 linear ft (448 m) of existing stream channel, and
relocate 476 linear ft (145 m) of stream channel. Per the project's CWA §§404/401
permits, the 476 linear ft of relocated channels count toward on-site stream mitigation.
Consequently, the entire project will result in 994 linear ft (303 m) of stream channel
loss. The AA section of R-2562A will fill 0.321 ac (0.130 ha) of surface waters (i.e.,
ponds), impact 1,079 linear ft (329 m) of existing stream channel, and relocate 476 linear
ft (145 m) of stream channel. Per the project's CWA §§404/401 permits, the 476 linear ft
of relocated channels count toward on-site stream mitigation. Consequently, the AA
section will result in 603 linear ft (184 m) of stream channel loss. The AB section's fill
in surface waters (i.e., ponds), impacted existing stream channel (listed as "stream
channel loss" in Table 5 of the project's April 14, 1999 CWA §§404/401 IP application),
and relocated stream channel equate to the area and linear distances authorized under the
project's CWA §§404/401 permits for that section of R-2562.
Table 11 depicts the revised jurisdictional surface water impacts for the AA and AB
sections of R-2562. Table 12 illustrates the revised jurisdictional surface water impacts
for just the AA section of the project. Permitted surface water impact area and linear
distances originate from the project's CWA §404 IP of March 7, 2000 and CWA §401
Water Quality Certification of February 22, 2000. The tables' shaded boxes represent

revised surface water impacts. Permitted surface water impact area and linear distances
originate from the project's CWA §404 IP of March 7, 2000 and CWA §401 Water
Quality Certification of February 22, 2000. The tables' shaded boxes represent revised
surface water impacts for a particular impact activity.
Site 3 surface waters, AA section (see enclosed revised permit drawing 13 of 24, dated 5/22/00)
The NCDOT is relocating an unnamed jurisdictional stream through an existing pond at
Site 3. The project's CWA §§404/401 permits authorize the fill of 0.158 ac (0.064 ha) of
the site's pond. Since the relocated jurisdictional stream will drain the remaining portion
of the pond not authorized to be filled, NCDOT Hydraulics Unit counted the entire pond
area as a fill in surface water impact. Enclosed revised permit drawing 13 of 24 (dated
5/22/00) illustrates the drained pond. The enclosed revised wetland/surface water impact
summary sheet (permit drawing 11 of 24, dated 5/22/00), and Tables 13 and D correctly

Site 9 surface waters, AA Section (see enclosed revised permit drawing 20A of 24, dated 5115100)
The linear distance of existing channel impacted has not changed from the project's
original CWA §§404/401 permits. Existing channel impact of 13 linear ft (4 m) wasn't
included as part of Site 9's channel impacts on the project's April 14, 1999 permit
application and subsequently issued permits. This total was, however, accounted for in
the initial permit application and permits under the amount of required compensatory off-
site stream mitigation. An additional 13 linear ft of stream channel impacts at Site 9
appear in Tables 14 and D solely for accounting purposes.

Site 10 surface waters, AA Section (see enclosed revised permit drawing 20B of 24, dated 5/22/00)
Site 10 is an unnamed stream associated with Murphy Swamp. In order to reduce this
site's initially proposed 1.666 ac (0.674 ha) of wetland drainage impacts, NCDOT
Hydraulics Unit eliminated the relocated channel that drained the site's wetlands. A 1500
mm reinforced concrete pipe measuring 131 ft (40 m) in length will now convey water
along Site I O's jurisdictional stream, instead of the initially permitted 164 linear ft (50 m)
of relocated stream channel: The project's CWA §§404/401 permits counted the initially
proposed 164 linear ft of relocated stream channel as compensatory on-site stream
mitigation. The NCDOT proposes to compensate for the lost 164 linear ft of on-site
stream mitigation through an additional 328 linear ft (100 m) off-site stream mitigation at
a 2:1 ratio. Enclosed revised permit drawing 20B of 24 (dated 5/22/00) illustrates the
14
revised hydraulic conveyance at Site 10. The enclosed revised wetland/surface water
impact summary sheet (permit drawing 11 of 24, dated 5/22/00) and Tables 15 and D

Compensatory Wetland/Stream Mitigation
Wetland Mitigation
The NCDOT Project Development and Environmental Analysis Branch proposes to
revise the project's permitted compensatory wetland mitigation from Dowd Dairy Farm
Mitigation Site. The mitigation site is located in north central Bladen County,
approximately 7 miles (11 km) north of Elizabethtown and 2 miles (3 km) east of White
Oak. State Route (SR) 1324 (Dowd Dairy Farm Road) borders the site to the north, SR
1332 (Oak Grove Church Road) lies to the west, and dense forest is situated south and
east of the site. The site, which sits along a Coastal Plain interstream divide between
Ellis Creek to the west and Palmer Branch to the east, falls within the Cape Fear River
subbasin 03-06-16 and Hydrologic Unit #03030005. The wetland and surface water
impacts associated with R-2562AA/AB fall within the Cape Fear River subbasins 03-06-
15 and 03-06-16 and Hydrologic Unit #03030004 and #03030005.
Dowd Dairy Farm Mitigation Site consists of approximately 638 ac (258 ha) of prior-
converted (PC) cropland and approximately 20 ac (8 ha) of cropland on non-hydric soils.
Prior-converted cropland is a wetland that was manipulated and cropped prior to 23
December 1985 to the extent that it no longer exhibits important wetland functions.
Prior-converted croplands do not fall under the regulatory jurisdiction of CWA §404.
Compensatory wetland mitigation credits for the Dowd Dairy Farm Mitigation Site are
based on wetland functions generated by restoration and comparison of restored functions
to impacted wetland resources. A base-line estimated mitigation plan for the site includes
13 ac (5 ha) of restored riverine (headwater) wetlands, 518 ac (210 ha) of restored non-
riverine wetlands, 20 ac (8 ha) of restored wetland/upland ecotones, and 107 ac (43 ha) of
restored wetland buffers that are adjacent to perimeter canals. The NCDOT's Wetland
Mitigation Plan: Dowd Dairy Farm Wetlands, Bladen County, North Carolina (May
1997) contains further information on this mitigation site.
15
Site construction for Dowd Dairy Mitigation Site is divided into two parts, Phase I and
Phase II. Phase I consisted of clearing/grubbing/ripping most of the site, filling lateral
ditches, and adding ditch plugs. The NCDOT completed construction activities under
Phase I in September 1998. Planting for the first phase was completed in March 1999.
All monitoring wells were installed during Phase I. The NCDOT is conducting on-going
hydrologic monitoring at the mitigation site. Activities conducted under the second phase
of construction will include filling the central channel and installing related ditch plugs.
Phase II construction activities began during the summer of 1999, were halted for an
extended period of time due to wetness from several hurricanes, and will be completed by
the summer of 2000. The final planting for Phase II will be completed by March 2001.
In order to offset 11.154 ac (4.514) ha of permanent wetland impacts associated with the
project, NCDOT proposes to debit 5.8 ac (2.3 ha) of restored riverine wetlands and 16.4
ac (6.6 ha) of restored non-riverine wetlands from Dowd Dairy Farm Mitigation Site.
This project is one of three NCDOT projects that use a portion of Dowd Dairy Farm
Mitigation Site for compensatory wetland mitigation. The other two NCDOT projects
that utilize the mitigation site are R-2238AA/ABBA (NC 87 in Cumberland and Harnett
Counties) and R-2204A (NC 11 in Duplin County). Tables 16 and 17 update the R-
2562AA/AB compensatory wetland mitigation requirements authorized in the project's
CWA §§404/401 permits. Table 16 summarizes the compensatory wetland mitigation
proposal for R-2562AA/AB. Table 17 outlines the accumulative compensatory wetland
mitigation taken from Dowd Dairy Farm Mitigation Site. Revised mitigation debit ledger
maps and x-y coordinates of Dowd Dairy Farm Mitigation Site are also included as an
attachment to this permit modification application letter.

Stream Mitigation
According to Table D, the project impacts 1,470 linear ft (448 m) of existing stream
channel and relocates 476 linear ft (145 m) of stream channel. Per the project's CWA
§§404/401 permits, the 476 linear ft of relocated channels count toward 1:1 on-site stream
mitigation. After subtracting out the project's revised on-site site stream mitigation
credits, the entire project will result in 994 linear ft (303 m) of stream channel loss (i.e.,
1,470 linear ft existing stream channel impacted - 476 linear ft relocated stream channel
as on-site stream mitigation = 994 linear ft stream channel loss). In order to offset the
stream loss, NCDOT proposes to mitigate for 1,988 linear ft (606 m) of streams under its
2:1 off-site compensatory stream mitigation requirements.
The project's CWA permits authorize compensatory off-site stream mitigation for 1,660
linear ft (506 m). Per a letter dated June 12, 2000, NC Wetlands Restoration Program
(NCWRP) received check number. 1016493 in the amount of $207,500 as payment for the
compensatory off-site stream mitigation requirements authorized under the project's
CWA §§404/401 permits. As specified under the project's CWA permits, NCWRP will
restore 1,660 linear ft (506 m) of jurisdictional stream in Cataloging Unit 0303004 of the
Cape Fear River Basin.
The NCDOT lost 164 linear ft (50 m) of permitted on-site stream mitigation because of
the additional 1500 mm reinforced concrete pipe proposed for Site 10's jurisdictional
stream along the AA section of the project. Therefore, NCDOT proposes to compensate
for the lost on-site stream mitigation through an additional 328 linear ft (100 m) off-site
stream mitigation at a 2:1 ratio. The additional 328 linear ft of off-site stream mitigation
plus the permitted 1,660 ft of off-site stream mitigation provided by NCWRP comprise
the project's revised off-site stream mitigation figure of 1,988 linear ft now required for
R-2562AA/AB. In a letter dated September 6, 2000, NCDOT requested from NCWRP
an additional 328 linear ft of off-site stream mitigation to compensate for the lost on-site
stream mitigation. At a cost of $125 per stream mitigation unit, NCDOT proposes to pay
NCWRP an additional $41,000 for compensatory stream mitigation.
17
Authorization Request
In summary, construction of the proposed NC 87 widening will permanently impact
11.154 ac (4.514 ha) and temporarily impact 0.743 ac (0.301 ha) of jurisdictional
wetlands, fill 0.619 ac (0.251 ha) of surface waters (i.e., ponds), impact 1,470 linear ft
(448 m) of existing stream channel, and relocate 476 linear ft (145 m) of stream channel.
Per the project's CWA §§404/401 permits, the 476 linear ft of relocated channels count
toward on-site stream mitigation. Consequently, the entire project will result in 994
linear ft (303 m) of stream channel loss. In order to offset jurisdictional wetland impacts,
NCDOT proposes to provide 5.8 (2.3) of restored riverine wetlands and 16.4 ac (6.6 ha)
of restored.non-riverine wetlands from Dowd Dairy Farm Mitigation Site. In order to
compensate for 164 linear ft (50 m) of lost on-site stream mitigation, NCDOT also
proposes to pay NCW" an additional $41,000 for compensatory off-site stream
mitigation.
Based upon the revised impacts to jurisdictional wetlands and streams and revised
compensatory wetland and stream mitigation, NCDOT requests authorization to modify
the project's CWA §404 IP of March 7, 2000 and CWA §401 Water Quality Certification
of February 22, 2000 in order to continue constructing the project. Enclosed are revised
permit drawings and wetland mitigation debit ledger maps that depict the project's
updated wetland and stream impacts and compensatory wetland mitigation requirements.
A $475 check addressed to NCDWQ is also enclosed for application to a CWA §401
Water Quality Certification modification. If you have any questions or need additional
information, please call Mr. Tim Bassette at [phone] 005.
