Approximately I ,485 feet of 54-inch and 6,210 feet of 36-inch sewer will he installed parallel to the existing
36-inch sewer along Irwin Creek from the Norfolk Southern Railroad tracks (lust south of Wilkinson Blvd to
West Trade Street in uptown Charlotte. In addition approximately 1,750 feet of 36-inch sewer will be
installed on the west side of Stewart Creek from the Irwin/Stewart Creek confluence to Freedom Drive Also
included in the project is construction of 170 feet of 18-inch sewer to interconnect an existing 18-inch sewer.

sewer will also provide for future growth in the area.
14. STATE REASONS WHY IT IS BELIEVED THAT THIS ACTIVITY MUST BE CARRIED
OUT IN WETLANDS (INCLUDE ANY MEASURES TAKEN TO MINIMIZE
WETLAND IMPACTS)
The sewer must be constructed along Irwin Creek and Stewart Creek so that wastewater flows can be
conveyed by gravity. The sewer route was selected to minimize impacts to wetlands and streams. All
stream crossings by the sewers will be subaqueous and roughly perpendicular to the streams. The
sewer will be located below grade in all areas. Stream crossings will be restored with rip rap below the
ordinary high water mark and vegetation plantings (silky dogwood, silky willow, and elderberry) above
the high water mark. The stream banks will be restored to their original contours. Anti-seep collars
will be installed every 1,000 feet along the sewer route. Other than stream crossings no wetlands will
be disturbed during construction.

sewer will be installed parallel to an existing 36-inch sewer along the west side of Irwin
Creek from the Norfolk Southern railroad tracks (just south of Wilkinson Boulevard) to West
Trade Street in uptown Charlotte. The sewer will be interconnected with the existing sewer
to convey dry-weather flow from the Stewart Creek drainage basin and wet-weather flow
form the Irwin Creek and Stewart Creek drainage basins. The new sewer will be connected
to the Contract I portion of 54-inch relief sewer (soon under construction), which conveys
wastewater to the Irwin Creek Wastewater Treatment Plant.
Approximately 1,750 feet of 36-inch relief sewer along Stewart Creek. This gravity sewer
will be installed along the west side of Stewart Creek from the confluence of Irwin and
Stewart Creeks to Freedom Drive. The sewer will be interconnected with the existing sewer
and will convey dry-weather and wet-weather flow from the Stewart Creek drainage basin to
the Irwin Creek relief sewer. Construction of the sewer will allow the abandonment of an
existing inverted siphon under Stewart Creek.
Approximately 170 feet of 18-inch gravity sewer adjacent to a tributary of Stewart Creek
This sewer will be installed to intercept flow from an existing sewer on the west side of
Stewart Creek and will allow the abandonment of a second inverted siphon under the
tributary.
The 54-inch Irwin Creek relief sewer will cross Stewart Creek once at the confluence of Irwin
Creek and Stewart Creek. The 36-inch Irwin Creek relief sewer will cross Irwin Creek once near
West Trade Street. The 36-inch Stewart Creek relief sewer will cross Stewart Creek once and a
Stewart Creek tributary once. A 30-inch interconnector sewer will also cross Stewart Creek once
near Freedom Drive. At each stream crossing, the sewer will be grouted in a continuously welded
steel casing laid in a trench crossing the stream. All crossings will be subaqueous, and the top of
the pipe will be at least 1 foot below the bottom of the stream bed. Original stream bank contours
will be restored after construction. Rip rap will be used to restore the stream banks below the
high water mark, and dormant cuttings of silky dogwood (Corpus amomum), silky willow (Salix
sericea), and elderberry (&mbucus canandensis) will be used above the high water mark.

Correspondence with Natural Heritage Program
Correspondence from Ms. Susan Reece Giles, NC Natural Heritage
Program, confirming that one endangered species has been
historically reported near the project area (1 mile downstream of the
first phase of the project -- not in Contract II area), but it was not
found in a 1987 survey (11/12/97 -- 5 pages)

SUBJECT: Rare Species, High Quality Natural Communities, and Significant Natural
Heritage Areas at the Proposed Relief Sewer/Flow Equalization Facility/
Pump Station Project, Charlotte, Mecklenburg County, North Carolina.
Dear Ms. Boone:
The North Carolina Natural Heritage Program has a record of one known rare species occurring
approximately 1-mile west and upstream of the proposed pump station and sewer pipeline project
in Charlotte, Mecklenburg County, North Carolina. The Federal/State Endangered freshwater
mollusk, Carolina Heelsplitter (Lasmigona decorata) was historically reported in Irwin Creek
approximately 1.0 mile west and upstream of the proposed pump station but not found in a recent
survey done in 1987.
Since the pipeline will be crossing the creek and tributaries several times, following the US Corp of
Engineers Best Management Practices for waterway sites is greatly advised.
Enclosed is a list of rare species that are known to occur in the Mecklenburg County. If suitable
habitat for any of these species occurs in the project areas, then those species may be present at the
project sites. To be certain that this site does not contain rare species, a field survey would need to
be conducted.
Contact me at the address below or call me at [phone] if you have any questions or need
further information.
Sincerely,
Susan Reece Giles, Information Specialist

NC NATURAL HERITAGE PROGRAM COUNTY SPECIES LIST COVER SHEET
The county species list from the NC Natural Heritage Program is a listing of the elements (rare species, natural communities, and
special animal habitats) known to occur in a county. The information on this printout is compiled from a variety of sources,
including field surveys, museums and herbaria, literature, and personal communications. The Heritage Program's Biological and
Conservation Database (BCD) is dynamic, with new records being added and old records being revised as new information is
received. The BCD was developed and is maintained using methodology developed by The Nature Conservancy. The enclosed list
cannot be considered a definitive record of natural heritage elements, and it should not be considered a substitute for field surveys.
When this information is used in any document, we request that the printout date be given and that the NC Natural Heritage
Program be credited.
This cover sheet explains the four columns of status codes that are given on the right-hand side of the county list printout.
STATE STATUS
CODE STATUS
E Endangered
T Threatened
SC Special Concern
C Candidate
CODE STATUS
P Proposed (E, T, or C)
SR Significantly Rare
EX Extirpated
WL Watch List
Plant statuses are determined by the Plant Conservation Program (NC Department of Agriculture) and the Natural Heritage
Program (NC Department of Environment and Natural Resources). E, T, and SC species are protected by state law (Plant
Protection and Conservation Act, 1979). C and SR designations indicate rarity and the need for population monitoring and
conservation action. WL indicates a species not warranting active monitoring, but believed to of conservation concern.
Animal statuses that indicate state protection (E, T, and SC) are published in Endangered Wildlife of North Carolina, March 16,
1992, Nongame and Endangered Wildlife Program (NC Department of Environment and Natural Resources). SR and EX statuses
are Natural Heritage Program designations. SR indicates rarity and the need for population monitoring and conservation action.
WL indicates a species not warranting active monitoring, but believed to of conservation concern.
FEDERAL STATUS
This status is designated by the US Fish and Wildlife Service. Federally listed Endangered and Threatened species are protected
under the provisions of the Endangered Species Act of 1973, as amended through the 100th Congress. Unless otherwise noted,
definitions are taken from the Federal Register, Vol. 56, No. 225, November 21, 1991 (50 CFR Part 17).
CODE STATUS DEFINMON
E Endangered A taxon "in danger of extinction throughout all of a significant portion of its range. "
T Threatened A taxon "likely to become an endangered species within the foreseeable future throughout all of a
significant portion of its range."
P Proposed A taxon proposed for official listing as endangered or threatened.
C Candidate A taxon under consideration for which there is sufficient information to support listing. This category was
formerly designated as a Candidate 1 (Cl) species.
FSC Federal Species of Concern. Formerly defined as a taxon under consideration for which there is
insufficient information to support listing; formerly designated as a Candidate 2 (C2) species. Currently,
the US Fish and Wildlife Service does not recognize this designation.
T(S/A) Threatened due to Similarity of Appearence. "The American Alligator is threatened due to similarity of
appearance with other rare crocodilians and is listed for trade purposes. The species is no longer
biologically endangered or threatened and is not subject to Section 7 consultation." (U.S. FWS)
Please note that the US Fish and Wildlife Service no longer recognizes the following categories:
3A Candidate 3A A taxon formerly under consideration for listing, but for which there is "persuasive evidence of
extinction. "
3B Candidate 3B A taxon formerly under consideration for listing, but which current taxonomic understanding does not
support as a distinct entity meeting the Endangered Species Act's definition of "species. "
3C Candidate 3C A taxon formerly under consideration for listing, but which has been "proven to more abundant or
widespread than previously believed and/or (which is] not subject to any identifiable threat."
These ranks are determined by The Nature Conservancy's system of measuring rarity and threat status. "Global" refers to
worldwide ranks and "State" to statewide ranks.
STATE RANK DEFIMTIONS
S1 Critically imperiled in North Carolina because of extreme rarity or otherwise very vulnerable to extirpation in the state.
S2 Imperiled in North Carolina because of rarity or otherwise vulnerable to extirpation in the state.
S3 Rare or uncommon in North Carolina.
S4 Apparently secure in North Carolina, with many occurrences.
S5 Demonstrably secure in North Carolina and essentially ineradicable under present conditions.
SA Accidental or casual; one to several records for North Carolina, but the state is outside the normal range of the species.
SH Of historical occurrence in North Carolina, perhaps not having been verified in the past 25 years, and suspected to be still
extant in the state.
SR Reported from North Carolina, but without persuasive documentation for either accepting or rejecting the report.
SX Believed to be extirpated from North Carolina.
SU Possibly in peril in North Carolina, but status uncertain; more information is needed.
S? Unranked, or rank uncertain.
B Rank of breeding population in the state. Used for migratory species only.
_N Rank of non-breeding population in the state. Used for migratory species only.
_Z_ Population is not of significant conservation concern; applies to transitory, migratory species.
GLOBAL RANK DEFINITIONS
G1 Critically imperiled globally because of extreme rarity or otherwise very vulnerable to extinction throughout its range.
G2 Imperiled globally because of rarity or otherwise vulnerable to extinction throughout its range.
G3 Either very rare and local throughout its range, or found locally in a restricted area.
G4 Apparently secure globally, although it may be quite rare in parts of its range (especially at the periphery).
G5 Demonstrably secure globally, although it may be quite rare in parts of its range (especially at the periphery).
GH Of historical occurrence throughout its range.
GX Believed to be extinct throughout its range.
GU Possibly in peril, but status uncertain; more information is needed.
G? Unranked, or rank uncertain.
G_Q Of questionable taxonomic status.
T_ Status of subspecies or variety; the G rank refers to the species as a whole.
Elements following county names marked with 1 or 2 asterisks indicate obscure or historic records.
* Obscure record: the date the element was last observed in the county is uncertain.
** Historic record: the element was last observed in the county over 50 years ago.
Scientific and common names listed in parentheses are synonyms listed in US Fish and Wildlife Service, 1992, Endangered and
Threatened Species of the Southeastern United States (The Red Book).

Finding of No Significant Impact (FONSI) and EA Correspondence
Correspondence from Ms. Gloria Putnam, NC DWQ (Lead Agency)
and Ms. Chrys Baggett, NC Department of Administration (State
Clearinghouse) confirming that the Environmental Assessment
comments have been sufficiently addressed (1/13/99 - 2 pages)
FINDING OF NO SIGNIFICANT IMPACT
Environmental Assessment for the Irwin Creek Relief Sewers,
Pump Station, and Flow Equalization Facilities EA
Mecklenburg County, Catawba River Basin
An Environmental Assessment (EA) has been prepared, pursuant to the requirements of the
North Carolina Environmental Policy Act, for the proposed construction of a relief sewer, pump
station, and flow equalization basin to service the Irwin Creek drainage area which is located in
the north and northwestern portions of Charlotte in Mecklenburg County.
The proposed Irwin Creek relief sewers are located parallel to an existing sewer line along Irwin
Creek in Charlotte from the Irwin Creek WWTP to West Trade Street with another portion of the
relief sewer paralleling the existing sewer beginning at the confluence of Irwin.Creek and Stewart
Creek and continuing along the west side of Stewart Creek to Freedom Drive. The pump station
and flow equalization basin are to be constructed at the Irwin Creek WWTP on the west side of
the Creek. Wastewater from the Irwin Creek and Stewart Creek relief sewers will be conveyed to
the Irwin Creek WWTP. In dry-weather conditions, flow in the sewer will consist of only that
portion coming from the Stewart Creek side. This flow will be diverted to the McAlpine Creek
WWTP by an existing pipeline which already diverts part of the wastewater flow from Irwin
Creek to the McAlpine facility. During wet-weather periods, the proposed relief sewer will be
able to convey the wastewater flows from the Irwin Creek service areas which cannot be
adequately handled by the existing sewer. The flow will be pumped to the equalization basin for
treatment at the Irwin Creek WWTP.
Although the pipeline construction route was selected in order to minimize negative impacts to the
environment, there are several stream crossings proposed. Irwin Creek will be crossed once and
Stewart Creek three times. The pipeline is expected to be installed by temporarily diverting the
streams. Once the pipeline is installed, the appropriate backfill and erosion control techniques
will be used to comply with the Corps of Engineers Nationwide Permit 12. Stabilization of the
creek banks will take place immediately after construction by restoring the original stream
contours and seeding activities. Erosion in these stream crossing areas will be reduced by the use
of rip rap. No instream activities will occur between the months' of April to May in order to
reduce the impact to fish.
This EA and Finding of No Significant Impact (FONSI) are prerequisites for the issuance of
non-discharge permits by the Division of Water Quality for the pump station, distribution
pipeline, and equalization basin.
Based on the findings of the EA and on the impact avoidance and mitigation measures
contained therein, it is concluded that the proposed project will not result in significant impacts
to the environment. Pending approval by the State Clearinghouse, the environmental review for
this project will be concluded. An environmental impact statement will not be prepared.
