Subject: Application for Section 404 Regional General Permit No. 198200031 and 401 Water
Quality Certification for the proposed Widening of NC 24/27 from NC 740 in
Albemarle in Stanly County to the Troy Bypass in Montgomery County, Federal Aid
Project No. STBG-0024(083), Divisions 10 & 8, TIP Nos. R-2530B, B-4974 & R-2527.
Debit $570 from WBS 34446.1.5.
Dear Sir:
The North Carolina Department of Transportation (NCDOT) proposes to widen NC 24/27 from NC 740
in Albemarle located in Stanly County to the Proposed Troy Bypass, west of Troy in Montgomery
County. The project was combined from three separate projects; R-2530B, B-4974 and R-2527; under
one NEPA document in 2006 due to logical termini. R-2530B involves widening existing NC 24-27 from
west of NC 740 to the Pee Dee River from a two to three-lane facility to a four-lane divided facility and
will also involve a superstreet design in the areas where curb and gutter is proposed. B-4974 involves
rehabilitating existing Bridge No. 51 over the Pee Dee River on the Stanly / Montgomery County line. R-
2527 involves widening existing NC 24-27 from a two-lane facility to a four-lane divided facility from
east of the Pee Dee River to the Troy Bypass. The total project is approximately 14.6 miles in length.
Please see the enclosed PCN, Division of Mitigation Services (DMS) mitigation acceptance letters, permit
drawing review minutes (4B and 4C), Draft MOA, State Stormwater Management Plan (SMP), utility
drawings, permit drawings, and design plans for the above referenced project.
Purpose and Need
The purpose of these projects is to improve traffic flow and level of service (LOS) on the section of NC
24-27 between NC 740 in Albemarle to the proposed Troy Bypass, west of Troy, and to rehabilitate a
bridge across the Pee Dee River that addresses the needs of highway users.

MERGER INFORMATION
In compliance with the NEPA/404 Merger Process, the following Concurrence Points were reached for
this project:
R-2530B/B-4974: 4B: October 19, 2016 4C: May 16, 2018.
PROJECT SCHEDULE
R-2530B and B-4974 are currently scheduled to let to construction on March 19, 2019, with a review date
of January 2, 2019. B-4974 has Design Build Let of November 20, 2018 with deck rehabilitation to begin
shortly thereafter but no ground disturbing activities will commence until after the Construction Let in
March 2019. R-2527 is currently slated to Let in February 16, 2021.
RESOURCE STATUS
Waters within the project area are located in the Yadkin Pee Dee River Basin (HUC 03040104, within
Subbasins 03-07-08, 03-07-10, and 03-07-15). There are no Outstanding Resource Waters (ORW) or
High Quality Waters (HQW) within the project area. No Water Supply Waters (WS-I or WS-II) waters
occur within 1.0 mile of the project area; however, the Pee Dee River and its UTs are designated as WS-
N, B; CA (water supply watershed).
Wetland and stream determinations within R-2530B, B-4974 and R-2527 were conducted using the field
delineation method outlined in the 1987 Corps of Engineers Wetland Delineation Manual and the 2012
Eastern Mountains and Piedmont Supplement. The projects were initially verified between 2006 and
2008. Ronnie Smith from ACOE and David Wainwright of DWR field reverified the wetlands and
surface waters in 2012 through 2014.
303(dLpaired Waters:
Mountain Creek is currently listed on the North Carolina 2016 Final 303(d) list of impaired waters for
having impaired ecologicaUbiological integrity for benthos. The Pee Dee River (Lake Tillery) is currently
listed on the 2016 Fina1303(d) list for PCBs in fish tissue.
IMPACTS TO WATERS OF THE U.S.
Tables 1, 2 and 3 summarize the impacts to jurisdictional water resources for R-2530B/B-4974. Site
numbers correspond with the permit (hydraulic) drawings included in this application. The stream and
wetland numbers correspond to the NRTR and the FONSI. The pond/open water impacts were not
identified as mitigable at the 4B and 4C meetings for R-2530BB-4974. (R-2527 is only preliminary
design/impacts).

Utility Impacts
Wetlands at Pennit Sites 10, 14, 15, and 21 have mechanized or hand clearing impacts from utility easements — these impacts (<0.05 ac) are included in
the impact tables and permit drawings for this project.
Wetland W8 at Permit Site 6 will have utility impacts (0.21ac) from open trenches that the City of Albemarle will require for the installation of water
and sewer lines to a new lift station. These utility wetland impacts have been included in Table 1 above. Please see utility drawings for a site narrative
and impacts (attached to the PCN).
Utility impacts for R-2527 will be determined when that section reaclles final design.

MITIGATION OPTIONS
The NCDOT is committed to incorporating all reasonable and practicable design features to avoid and
minimize jurisdictional impacts, and to provide full compensatory mitigation of all remaining,
unavoidable jurisdictional impacts. Avoidance measures were taken during the planning and NEPA
compliance stages; minimization measures were incorporated as part of the project design.
Avoidance and Minimization:
NCDOT has avoided impacting many wetlands and streams and reduced impacts to wetlands and streams
to the greatest extent practicable. Other specific examples of avoidance and minimization measures
include:
• Avoiding direct discharges where practicable.
Culvert barrels with sills will be back filled with native material or class A rip rap to sill height.
Native material will consist of material that is excavated from the stream bed or floodplain at
the project site during culvert construction. Native material is subject to approval by the
engineer and may be subject to permit conditions. Class A rip rap may be used to supplement
the native material. If rip rap is used, native material should be placed on top to fill voids and
provide a flat surface for animal passage
• For upstream and downstream floodplain bench channel improvements, the floodplain bench
will be comprised of Class I rip rap with native material to top of sill elevation and coir fiber
matting cover (per comment received at 4B meeting).
• Due to the water supply reservoir within project limits, a Critical Area (CA) was identified in the
FONSI. The CA is defined as the area within '/z mile from the water supply reservoir normal pool.
Within the CA, a 25-year storm is used for erosion control design. Although only a portion of the
project falls within the CA, the entire erosion control design was based on the 25-year storm
event to further protect the surrounding watershed.
The filtration basins will provide water quality treatment for a broad spectrum of water
quality parameters of concern. As stormwater is temporarily detained, suspended
sediments and some phosphorus are captured through sedimentation. During
infiltration and other chemical processes, metals and additional phosphorus are
removed. Microbial activity that occurs in the media helps to reduce nitrogen and
hydrocarbons. As the surface layer is exposed to sunlight and allowed to dry, pathogens
are treated. Median filters with relatively deep media layers can help abate runoff
temperatures.
• Media filters will additionally provide peak flow attenuation, reducing the peak flow for
the protection of downstream conveyances, reducing the chance for degradation and
sediment loss.
• Coordination of erosion control basins with hazardous spill basins to limit impacts if
possible by converting basin EC basin over to permanent spill basin.
Site Snecific Avoidance and Minimization Measures:
• Use of low flow sills set at stream bed elevation in main barrel of multiple barrel and in single
barrel box culverts. Low flow sills were used in both barrels of box culvert at Sta. 38+76 -L- due
to lack of cover (only 4' height opening), need for opening area to meet hydraulic guidelines and
inability to raise proposed grade significantly due to surrounding developed areas.
• Use of high flow sills set at floodplain bench elevation on high flow barrels of multiple barreled
box culverts at Sta. 24+95 -Y2- and 381+64 -L-, to help maintain the natural stream width and
depth through the main barrel.
• NCDOT avoided impacts at Permit Site 41 by shortening the culvert thereby reducing permanent
and temporary stream impacts and avoiding the FERC Resource Protection Management line
(depicted as Do Not Disturb on permit drawings).
� Use of hazardous spill basins in and around critical area of Lake Tillery. Critical area where
hazardous spill basins are required begins around Sta. 258+00 -L- and runs to the end of the
project.
• Modified, linear, base ditch basins with check dams were provided at basin locations 1
(from Sta. 276+50 to 277+75 -L- (RT)), location 2(from Sta. 290+50 to 293+00 -L- (RT)),
location 3(from Sta. 307+00 to 308+50 -L- (LT)), and location 4(from Sta. 331+25 to
334+00 -L- (LT)). These modified basins will limit the overall basin footprint, since they
are in areas of very steep terrain where traditional basins were not practical. They will
provide storage for low flow events or spills, within the ditch parameters, will slow
down the spills with the use of check dams and will provide a headwall that can be
blocked off in case of a spill.
• The basins at stations 364+00 -L- (LT) and 382+50 -L- (RT) are designed as rock lined,
detention type basins with weir outfalls approximately 18" elevated above the bottom
of the basin. These basins will help to detain any spills, while minimizing maintenance
and safety concerns due to the steep terrain and difficulty accessing.
Hazardous spill basins were modified to filtration basins at Sta. 352+75 -L- (RT) and Sta.
380+00 -L- (RT) to provide some long-term water quality benefits. The filtration basins
are designed and sized to capture and treat the water quality volume that will consist of
all the runoff from the new built-upon area for 80 to 90% of the average annual rainfall.
This will result in a water quality design storm of 1.5 inch. The filtration basins were used in
areas where vegetative conveyance was not possible due to the steep terrain requiring rip rap
protection in the proposed swales to protect from high velocities.
Please refer to the attached Stormwater Management Plan for additional Avoidance and Minimization
measures.
