Subject: Wolfspeed silicon Carbide Semiconductor Chip Wafer Manufacturing Facility
Fast Track sewer System Extension Application
CAM Outfall No.1 (Oflf'site Gravity Sewer System)
loon Carolina core Parkway, Slier City, NC
Dear Mr. Allen:
We are requesting review and approval of the attached Fast Track Sewer System Extension
Application required for the construction of a public sewer collection system that is associated with
the proposed development of the Wolfspeed silicon carbide semiconductor chip wafer
manufacturing facility located at 1000 Carolina Core Parkway, in Slier City, Chatham County. The
sewer improvements addressed in this application include the construction quantities for the public
gravity sewer line shown on an attached exhibit reaching from a connection at the private sewer
main in the Wolfspeed project, at Carolina Core Parkway, flowing approximately 2,600 feet westerly
to the proposed new Slier City Pump Station (WO 0037114), all to be constructed in accordance with
North Carolina minimum design criteria. We have titled these sewer improvements the "CAM
Outfall No.1" for ease in identification. As you are aware a separate Fast Track Sewer System
Extension Application has been filed for the private onsite Wolfspeed sewer system, titled
"Wolfspeed HIBS Private Sewer",
The public CAM Outfall No,1 sewer pipeline will be constructed by Wolfspeed and will be
transferred to Slier City upon its completion. The sewer pipeline size will range from is -inches, at
the easterly connection to the Wolfspeed private sewer and crossing Carolina Core Parkway, up to
30-inches at the westerly termination at the Slier City pump station. The variation in size is
necessitated due to the changes in pipe slope at accommodate the existing terrain. The sewer pipe is
intended at this time to only convey sewage from the Wolfspeed Facility and is sized for an initial
average flow up to approximately 1.0 MGD, with an upper design flow capacity of 4.5 MGD.
The makeup of the sewage emanating from the Wolfspeed facility is estimated to be 5% domestic
sewage and 95% process waste water from the manufacturing process.

The Flow Tracking form being submitted indicates a "Zero" flow because the downstream
connection at the Slier City Pump station has not been constructed, we are requesting that the CAM
Outfall No.1 public sewer system extension be approved for "Zero" flow at this time with the ability
to revise the request and approval determination later when sewer allocation is available from Slier
City pursuant per their SOC compliance.
Permitting requirements for this public sewer include the state's approval of Erosion and
Sedimentation Control plans for sewer installation, submitted Initially 8-3-23, which are currently
and concurrently awaiting approval by Slier City as part of their Site Plan and Zoning Permit process
of Site Plan-07 (SP-07) for the CAM Outfall No. sewer project. Once SP-07 is approved, the Erosion
and Sedimentation Control plans will be returned to 140%The Slier City approval will include
acceptance of their riparian buffer requirements.
Related 401 and 404 permits covering the CAM Outfall No.1 project area have been included as
indicted above.
As relates to the downstream Siler City pump station, the downstream receiving connection for
CAM Outfall No.1, a nationwide 404 permit approval through the USACE was granted for the Slier
City pump station on 7-17-23 and the 401 Water Quality coverage was approved on 6-15-23 (DWR
NCDEQ permit No. WQ0037114).

SUBJECT: Department of the Army Memorandum Documenting General Permit Verification
1.0 Introduction and Overview
Information about the proposal subject to one or more of the United States Army Corps of Engineers'
(Corps') regulatory authorities is provided in Section 1, detailed evaluation of the activity is found in
Sections 2 through 4 5 and findings are documented in Section 5 6 of this memorandum. Further,
summary information about the activity including the administrative history of actions taken during
project evaluation is attached (ORM2 summary) and incorporated into this memorandum.
NOTE: This document uses the term pre -construction notification (PCN) to identify when notification
is sent to the Corps to evaluate a proposed activity on a case -by -case basis to ensure that the activity
will cause no more than minimal adverse environmental effects, individually and cumulatively for
verification under a general permit (GP). While PCN is commonly associated with Nationwide Permit
(NWP) verification requests, this document uses the term PCN for notification sent to the Corps for all
GP verifications (i.e., NWPs, Regional GPs, Programmatic GPs).
1.1 Applicant name: Wolfspeed, Inc., Chris McCann
1.2 Activity location: Latitude: 35.745872 Longitude:-79.528179 Location description: Project is
located north of U.S. Highway 64 West and east of J.C. Teague Road Extension, west of Slier
City, near the border of Randolph and Chatham Counties, North Carolina. The Chatham -Slier
City Advanced Manufacturing Site (CAM) is bordered to the northeast by Old US421 N. near
the Randolph, Chatham County border near Slier City, North Carolina.
1.3 Description of activity requiring verification:Thls verification would authorize the discharge
of fill material into 0.070 acre of wetland for a 122' long by 24" culvert to maintain hydrologic
connectivity under a driveway and an 8' riprap pad for velocity dissipation. An additional 0.040
acre of wetlands and 88 linear feet of stream will be temporarily impacted from open cut
trenching for sewer installation and access.
1.4 Existing conditions and any applicable project history:
After -the -fact: No.
1.4.1 Jurisdictional Determination:
Is this project supported by a Jurisdictional Determination? Yes, Delineation Concurrence 2/23/2023
1.5 Permit authority:
Table 1— Permit Authority
Section 10 of the Rivers and Harbors Act (33 USC 403) ❑
Section 404 of the Clean Water Act (33 USC 1344)
1.6 Applicable Permit: NWP 39
1.7 Waiver Discussion:

Does the activity require a written waiver of the NWP limits? No.
Activity requires a waiver from the requirements of a regional condition(s)? No.
2.0 Evaluation of the Pre -Construction Notification
2.1 Direct and indirect effects which are caused by the GP activity: The direct effects of the
proposed activity in waters would include the loss of jurisdictional waters (as specified
In Section 1.3) and their associated aquatic resource functions. The proposed activity
also has the potential to result in indirect effects to waters Including excess
sedimentation In downstream waters, disruption and/or killing of aquatic life in the
direct vicinity of the project area, Increase of downstream flows, and
blockingirestricting aquatic life passage transiting In and through the project area.
These indirect effects are expected to be minimal due to design criteria and Best
Management Practices (BMPs) required by Nationwide Permit General and Regional
Conditions. Additionally, indirect effects would be further reduced through the
Implementation of BMPs required by state, local, and Federal ordinances and
regulations.
2.2 Site specific factors: The project area is part of the 19,511-acre Upper Brush Creek
watershed that Is primarily composed of farmland and rural development. This project
site will further be expanded into a mega manufacturing site In the growing Slier City
area. This area has a long history of Intensive farming practices which has resulted in
long term degradation to aquatic resources. Given the urbanizing nature of the
watershed, the waters within the project area provide important aquatic resource
functions to downstream waters.
2.3 Coordination
2.3.1 Interagency Coordination
Was the PCN coordinated with other agencies? No.
was not conducted for the proposed project.
2.3.2 Corps internal coordination
Agency coordination is not required and
Was the PCN coordinated with other Corps business lines?
3.0 Mitigation
3.1 Avoidance and minimization
Provide brief description of how the activity has been designed on -site to avoid and minimize adverse
effects, both temporary and permanent, to waters of the United States to the maximum extent
practicable at the project site: The applicant provided a detailed statement describing their
efforts to avoid and minimized impacts to waters of the United States on the project site in the
preconstruction notification. Based on this information, the Corps believes the applicant has
avoid and minimized impacts to waters of the United State to the maximum extent practicable.
The applicant has adjusted the discharge from their stormwater outfall ponds to ensure there
will not be indirect Impacts from construction of road crossings.

Describe other mitigative actions including project modifications implemented to minimize adverse
project impacts? (see 33 CFR 320.4(r)(1)(i))
Applicant looked into constructing bridge to avoid all wetland/stream impacts; however, construction
would be cost prohibitive. Applicant avoided 92% of the onsite wetlands
3.2 Compensatory mitigation requirement
Is compensatory mitigation required for unavoidable impacts to jurisdictional aquatic resources to
reduce the individual and cumulative adverse environmental effects to a minimal level?
Yes.
Provide rationale: Compensatory mitigation is required to ensure minimal adverse
environmental effects. Mitigation is required both for the DOT access road crossing and the
onsite Wolfspeed access road and utility crossings.
3.3 Type and location of compensatory mitigation
3.3.1 Mitigation bank service area
Is the impact in the service area of an approved mitigation bank? Yes.
Does the mitigation bank have the appropriate number and resource type of credits available? No.
3.3.2 In -lieu fee program service area
Is the impact in the service area of an approved in -lieu fee program? Yes.
Does the in -lieu fee program have the appropriate number and resource type of credits available?
Yes.
3.3.3 Compensatory mitigation
Selected compensatory mitigation typetlocation(s): See Table
Table 2: Mitigation Type and Location
Mitigation bank credits
In -lieu fee program credits
0.193
Permittee-responsible mitigation under a watershed approach
Permittee-responsible mitigation, on -site and in -kind
Perm ittee-res onsible mitigation off -site and/or out of kind
3.3.4 Mitigation hierarchy
Does the selected compensatory mitigation option deviate from the order of the options presented in
§332.3(b)(2)-(6)? No.
If yes, provide rationale for the deviation, including the likelihood for ecological success and
sustainability, location of the compensation site relative to the impact site and their significance within

the watershed, and/or the costs of the compensatory mitigation project (see 33 CFR 33 CFR
332.3(a)(1)): There are no banks In the service area with the appropriate amount of credits
therefore the applicant utilized NCDMS for mitigation services.
3.3.5 Watershed approach
Does the selected compensatory mitigation option follow a watershed approach? Yes
Is the impact in a watershed with a watershed plan? Yes
If yes, is the compensatory mitigation consistent with the watershed plan? Yes
3.4 Amount of compensatory mitigation
Amount of compensatory mitigation: 0.193-acre riparian wetland
Rationale for required compensatory mitigation amount: This amount of compensatory mitigation
Is necessary to replace the permanent loss of WOUS and temporal loss at the mitigation site.
The Corps will require mitigation for the direct impacts, 0.07 acre at a 2:1 ratio and the 0.053-
acre Indirect impacts at a 1:1 ratio.
4.0 Compliance with Other Laws, Policies and Requirements
4.1 Section 7(a)(2) of the Endangered Species Act (ESA)
4.1.1 ESA action area:
Action area means all areas to be affected directly or indirectly by the Federal action and not
merely the immediate area involved in the action. The action area for this project
Includes not only the footprint of the fill (the direct effect), but also those areas of the
waters downstream of the proposed fill that might reasonably be affected by the
placement of that fill (the indirect effect), as well as those segments of the proposed
Interchange whose configurationialignment is dictated by the proposed fill (the
Interrelated actions), and those segments of the interchange that would have no
Independent utility apart from the proposed fill (the interdependent actions). As such,
the ESA action area for this project is: within the footprint of the regulated activities In
waters of the U.S., uplands immediately adjacent to those waters that would be affected
by the regulated activities In waters of the U.S., the portions of the existing interchange
which are constrained by the location of the impact areas, and waters downstream that
would be expected to be Impacted by the proposed activities; these areas comprise the
Interchange and downstream waters that would be affected by project construction.
4.1.2 Lead federal agency for Section 7 of the ESA
Has another federal agency taken steps to document compliance with Section 7 of the ESA and
completed consultation(s) as required? No.
4.1.3 Listed/proposed species and/or designated/proposed critical habitat

Are there listed or proposed species or designated critical habitat or proposed critical habitat that may
be present or in the vicinity of the Corps' action area? No. The Corps has determined that it has
fulfilled its responsibilities under Section 7(a)(2) of the ESA.
IPAC Species in Chatham County:
Tricolored bat (Perlmyotis subflavus) - Proposed Endangered - Proposed for Listing
Red -cockaded woodpecker (Picoides borealis) - Endangered - Listed
Cape Fear shiner (Notropis mekistocholas) - Endangered - Listed
Harperella (Ptilimnium nodosum) - Endangered - Listed
Atlantic pigtoe (Fusconaia masoni) - Threatened - Listed
Effect determination(s), including no effect, for all known species/habitat, and basis for
determination(s): Based on the latest version of the Natural Heritage Program's NHEO data and
a site visit, there are listed species located within or in the vicinity of the action area and this
activity Is one that may affect those listed species. The Corps has determined that the activity
may affect, but Is not likely to adversely affect species subject to the ESA.
Applicant submitted Endangered Species
the following effect determinations:
Red -cockaded woodpecker -no effect
Cape Fear shiner -no effect
Atlantic Pigtoe- no effect
Harparella-no effect
Habitat Assessment to FWS June 15, 2022, making
USFWS responded via email June 21, 2022, concurring with these determinations noting that
there is an occurrence of Atlantic Pigtoe roughly 1.5 miles downstream of the property and to
ensure extreme vigilance of erosion and sedimentation measures to prevent offsite Impacts to
listed species.
The Corps followed up with an email to USFWS about the potential Tricolored Bat listing and
USFWS stated that the applicant can clear trees prior to the listing of the species, but once
listed any further tree clearing may need additional review from USFWS.
4.1.4 Section 7 ESA consultation
Consultation with either the National Marine Fisheries Service and/or the U.S. Fish and Wildlife
Service was initiated and completed as required, for any determinations other than "no effect' (see
the attached "Summary" sheet for begin date, end date and closure method of the consultation).
Based on a review of the information above, the Corps has determined that it has fulfilled its
responsibilities under Section 7(a)(2) of the ESA.
4.2 Magnuson -Stevens Fishery Conservation and Management Act, Essential Fish Habitat (EFH)
N/A, there Is no essential fish habitat in this field office's area of responsibility.
4.2.1 Lead federal agency for EFH provisions of the Magnuson -Stevens Act
Has another federal agency taken steps to comply with EFH provisions of Magnuson -Stevens Act
with the Corps designated as a cooperating agency and has that consultation been completed? No.

4.2.2 Magnuson -Stevens Act
Did the proposed project require review under the Magnuson -Stevens Act? No.
4.3 Section 106 of the National Historic Preservation Act (Section 106)
4.3.1 Section 106 permit area
The permit area includes those areas comprising waters of the United States that will be directly
affected by the proposed work or structures, as well as activities outside of waters of the U.S.
because all three tests identified In 33 CFR 325, Appendix C(g)(1) have been met.
Final description of the permit area: All three test have been met and portions of the larger
project undertaken outside of waters of the U.S. are In the permit area. Activities undertaken
outside WOUS are included In the permit area because those activities are directly associated
and Integrally related with the authorized work and those activities would not occur but for the
authorization of the work within the WOOS.
4.3.2 Lead federal agency for Section 106 of the National Historic Preservation Act
Has another federal agency been identified as the lead federal agency for complying with Section 106
of the National Historic Preservation Act with the Corps designated as a cooperating agency and has
that consultation been completed? No.
4.3.3 Historic properties
Known historic properties? No. Based on the NCDCR "HPOWEB" service and aerial
photographs, there are no known historic properties located in the permit area or in close
proximity to the permit area.
Effect determination and basis for that determination: The Corps has determined the proposed
activity has no potential to cause effects to properties fisted or eligible for listing in the
National Register of Historic Places, because the activitiy is limited in nature and scope. This
activity is so limited in nature and scope that there is little likelihood of impinging upon a
historic property even If such properties were present within the affected area's).
Based on previous surveys and a letter from NC SHPO 16 potential sites were surveyed on the
Megasite (365 acres of the Slier City Factory (SCF) site), but "were determined not to be
eligible for listing on the NRHP due to a lack of Integrity and Inability to contribute further to
an understanding of the area's prehistory or history." The onsite graveyard, the Marley
Cemetery, should be avoided with a 30 foot buffer surrounding it. However, the Impacts for
this NWP do not include these areas and the permit area is limited to the impacts to waters
and immediately adjacent uplands. A subsequent archeological report was submitted
February 2023 on the 80-acre tract added to the SCF along US 64 and the report concluded the
two potential sites were not eligible for listing and SHPO concurred with a no effect
determination In their letter dated March 10, 2023.
4.3.4 Consultation with the appropriate agencies, tribes and/or other parties for effect determinations

Consultation was initiated and completed with the appropriate agencies, tribes and/or other parties for
any determinations other than "no potential to cause effects." (see the attached ORM2 Summary
sheet for begin date, end date and closure method of the consultation)
4.4 Tribal Trust Responsibilities
4.4.1 Tribal government-to-govemment consultation
Was govemment-to-government consultation conducted with Federally -recognized Tribe(s)? No.
There are no known tribal interests in the project area.
Provide a description of any consultation(s) conducted including results and how concerns were
addressed.
4.4.2 Other Tribal consultation
Other Tribal including any discussion of Tribal Treaty rights? No. There are no known tribal
Interests In the project area.
4.5 Section 401 of the Clean Water Act —Water Quality Certification (WQC)
4.5.1 Section 401 WQC. requirement
Is a Section 401 WQC required, and if so, has the certification been issued or waived? An individual
water quality certification is required, and has not been issued or waived to date. A
provisional general permit will be verified for this activity.
An Individual WQC was received via email 9/15/2023.
4.5.2 401(a)(2) Process
If the certifying authority granted an individual WQC, did the United States Environmental Protection
Agency make a determination that the discharge `may affect' water quality in a neighboring
jurisdiction? No
Provide an explanation of the determination of the effect on neighboring jurisdiction.
Onsite water flows into the Cape Fear River which discharges into the Atlantic Ocean. Email received
9/21/23.
4.6 Coastal Zone Management Act (CZMA)
4.6.1 CZMA consistency concurrence
Is a CZMA consistency concurrence required, and if so, has the concurrence been issued, objected
to, or presumed? NIA, a CZMA consistency concurrence is not required.

5.0 Special Conditions
5.1 Special condition(s) requirement(s)
Are special conditions required to ensure minimal effects, ensure the authorized activity is not
contrary to the public interest and/or ensure compliance of the activity with any of the laws above?
Yes.
5.2 Special condition(s)
Special condition 1:
a. This verification is authorized in conjunction with the impacts of the NCDOT access road.
Impacts for this joint request fall under the threshold of a Nationwide Permit and both projects
would not occur but for the construction of the other. Please note that future impacts and/or
phases of the Chatham-Siler City Advanced Manufacturing Site (CANT), and related activities
associated with Corps Action ID: SAW-2014-01632, may be considered part of a single and

complete project; these impacts may be considered cumulative with impacts authorized during
earlier phases with respect to compensatory mitigation and Nationwide Permit thresholds.
Current cumulative impacts to waters of the US for the CAM single and complete project include
a total loss of 0.07 acre of wetlands and 155 linear feet (0.0106 acre) of stream.
b. In order to compensate for impacts associated with this permit, mitigation shall be provided in
accordance with the provisions outlined on the most recent version of the attached Compensatory
Mitigation Responsibility Transfer Form. The requirements of this form, including any special
conditions listed on this form, are hereby incorporated as special conditions of this permit
authorization.
c. Suitable habitat for tricolored bat (Perimyods sub, flavus) may be present at the site. On September
14, 2022, the USFWS published a proposal in the Federal Register to list the tricolored bat as
endangered under the Endangered Species Act (ESA). The permittee understands and agrees that
all work associated with the clearing and removal of trees and removal or modification of culverts
must be completed prior to the effective date of the final listing in the Federal Register. Work
associated with the aforementioned activities not completed by that time must cease and the
permittee must contact the Corps' Rachel Capito, Rachel.A.Capito(a),usace.army.mil to determine
if additional coordination with the United States Fish and Wildlife Service is required under
Section 7 of the Endangered Species Act prior to continuing work.

by one foot for all culverts with a diameter greater than 48 inches, and 20% of the culvert diameter
for culverts having a diameter less than or equal to 48 inches, to allow low flow passage of water
and aquatic life. If the culvert outlet is submerged within a pool or scour hole and designed to
provide for aquatic passage, then culvert burial into the streambed is not required.
For structures less than 72" in diameter/width, and topographic constraints indicate culvert slopes
of greater than 2.5% culvert burial is not required, provided that all alternative options for flattening
the slope have been investigated and aquatic life movement/connectivity has been provided when
possible (e.g. rock ladders, cross -vanes, sills, baffles etc. j. Notification, including supporting
documentation to include a location map of the culvert, culvert profile drawings, and slope
calculations, shall be provided to DWR 30 calendar days prior to the installation of the culvert.
