III. Project Information
Attach a vicinity map clearly showing the location of the property with respect to local
landmarks such as towns, rivers, and roads. Also provide a detailed site plan showing property
boundaries and development plans in relation to surrounding properties. Both the vicinity map
and site plan must include a scale and north arrow. The specific footprints of all buildings,
impervious surfaces, or other facilities must be included. If possible, the maps and plans should
include the appropriate USGS Topographic Quad Map and NRCS Soil Survey with the property
boundaries outlined. Plan drawings, or other maps may be included at the applicant's discretion,
so long as the property is clearly defined. For administrative and distribution purposes, the
USACE requires information to be submitted on sheets no larger than 11 by 17-inch format;
however, DWQ may accept paperwork of any size. DWQ prefers full-size construction
drawings rather than a sequential sheet version of the full-size plans. If full-size plans are
reduced to a small scale such that the final version is illegible, the applicant will be informed that
the project has been placed on hold until decipherable maps are provided.
1. Name of protect: Rutman Creek Watershed Restoration Project
2. T.I.P. Project Number or State Project Number (NCDOT Only):

6. Property size (acres): 4,300
Name of nearest receiving body of water: UTs to Rutman Creek and the AICWW
River Basin: Tar-Pamlico 03020104
(Note - this must be one of North Carolina's seventeen designated major river basins. The
River Basin map is available at http://h2o.em-.state.ne.us/admin/maps/.)
9. Describe the existing conditions on the site and general land use in the vicinity of the project
at the time of this application: A majority of the site has been managed for agriculture and silvicultural
production. The site is surrounded by the Pocosin Lakes National Wildlife Refuge to the west, New Lake to the north
and land used for agricultural purposes on both the south and east.
Updated 1 t/1/2005
Page 6 of 12
10. Describe the overall project in detail, including the type of equipment to be used:
The existing ditches on-site will be filled in order facilitate the restoration of Rutman Creek Watershed. Backhoes,
bulldozers, and dump trucks will be used to plug and backfill existing agricultural ditches and canals. Disturbance
to waters of the US is limited to these impacts associated with plugging canals and resultant hydrologic restoration.
11. Explain the purpose of the proposed work:The purpose of this project is to help meet the mitigation requirements
of the PCS Phosphate mining operation. All three phases of this project total -4,300 acres of restoration enhancement
and preservation. All work is scheduled to be completed by 2011.
IV. Prior Project History
If jurisdictional determinations and/or permits have been requested and/or obtained for this
project (including all prior phases of the same subdivision) in the past, please explain. Include
the USACE Action ID Number, DWQ Project Number, application date, and date permits and
certifications were issued or withdrawn. Provide photocopies of previously issued permits,
certifications or other useful information. Describe previously approved wetland, stream and
buffer impacts, along with associated mitigation (where applicable). If this is a NCDOT project,
list and describe permits issued for prior segments of the same T.I.P. project, along with
construction schedules. The wetland status of this project has been evaluated by David Lekson of the Washington
USACE office. A JD request was submitted to Mr. Lekson in early August (2008) On-site field verification was provided
by the USACE that the larger collector canals are to be considered jurisdictional RPWs. The smaller lateral agricultural
ditches are not considered jurisdictional. Therefore, impacts are limited to the filling of the collector canals.
V. Future Project Plans
Are any future permit requests anticipated for this project? If so, describe the anticipated work,
and provide justification for the exclusion of this work from the current application.
This permit request covers all three phases of proposed ditch filling. No further requests are anticipated since this site
will not be used for development in the future. Rather, a conservation easement deed will be recorded - thus protecting
the wetland and stream restoration site in perpetuity.
VI. Proposed Impacts to Waters of the United States/Waters of the State
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
wetlands, open water, and stream channels associated with the project. Each impact must be
listed separately in the tables below (e.g., culvert installation should be listed separately from
riprap dissipater pads). Be sure to indicate if an impact is temporary. All proposed impacts,
permanent and temporary, must be listed, and must be labeled and clearly identifiable on an
accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial)
should be shown on a delineation map, whether or not impacts are proposed to these systems.
Wetland and stream evaluation and delineation forms should be included as appropriate.
Photographs may be included at the applicant's discretion. If this proposed impact is strictly for
wetland or stream mitigation, list and describe the impact in Section VIII below. If additional
space is needed for listing or description, please attach a separate sheet.
1. Provide a written description of the proposed impacts: Impacts are proposed for a total of sixteen
large collector canals which are jurisdictional The ditch plugs will total -900 linear feet Ditch fill is proposed for two
locations and will total 7,000 linear feet of impact. These features will be filled and graded using historic side-cast sp(
from the adjacent road network. The ditch fill activities will coincide with the stream restoration, enhancement and
preservation activities within the mitigation plan. (Please refer to Figure 5 or an illustration o the restoration activities.)

VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts. Proposed impacts are unavoidable
due to the type of project proposed. In order to restore and enhance non-riverine and riverine wetlands formerly occurring
on the property (via hydrologic restoration), the identified canals/ditches must be be plugged and filled.
VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
Updated 11/1/2005
Page 9 of 12
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on January 15, 2002, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete.
An applicant may also choose to review the current guidelines for stream restoration in DWQ's
Draft Technical Guide for Stream Work in North Carolina, available at
htlp://l12o.ei,ir.state.ne.us/ncwetlands/striiilzide.html.
Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
In light of the net benefit of large-scale restoration, no mitigation for impacts to jurisdictional tributaries (RPWs) is
proposed given the overall project goal of restoring 4,300 acres of the Rutman Creek Watershed. This project
should not require mitigation since it stands as the proposed mitigation for the PCS Phosphate mining project.
2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement
Program (NCEEP). Please note it is the applicant's responsibility to contact the NCEEP at
[phone] to determine availability, and written approval from the NCEEP indicating
that they are will to accept payment for the mitigation must be attached to this form. For
additional information regarding the application process for the NCEEP, check the NCEEP
website at httL)://h2o.enr.sttte.ne.us/wfl:)/index.htm. If use of the NCEEP is proposed, please
check the appropriate box on page five and provide the following information:
Amount of stream mitigation requested (linear feet): NSA
Amount of buffer mitigation requested (square feet):
Amount of Riparian wetland mitigation requested (acres):
Amount of Non-riparian wetland mitigation requested (acres):
Amount of Coastal wetland mitigation requested (acres):
