MEMORANDUM FOR RECORD
SUBJECT: Department of the Army Environmental Assessment and Statement of
Findings for the Above -Referenced Standard Individual Permit Application
This document constitutes the Environmental Assessment, 404(b)(1) Guidelines
Evaluation, as applicable, Public Interest Review, and Statement of Findings for the
subject application.
1.0 Introduction and Overview: Information about the proposal subject to one or
more of the Corps' regulatory authorities is provided in Section 1, detailed
evaluation of the activity is found in Sections 2 through 11 and findings are
documented in Section 12 of this memorandum. Further, summary information
about the activity including administrative history of actions taken during project
evaluation is attached (ORM2 Summary) and incorporated in this memorandum.
1.1 Applicant: Durham Public Schools, Mr. Bernard Hall
1.2 Activity location: 4804 and 4622 N. Roxboro Street, Durham, NC
1.3 Description of activity requiring permit: Culverting approximately 308 feet of
perennial stream channel for the construction of access road to the proposed
high school.
1.3.1 Proposed avoidance and minimization measures: The current site was selected
after evaluating twelve sites (including the existing Durham High School location)
for the construction of the new Durham High School. See attached Table. The
current site was selected for various environmental and constructability reasons.
Three build alternatives were investigated for the current site. The preferred
alternative impacts the least amount of stream and avoids all wetland. Alternative
1 impacted 991 feet of stream and 1.8 acres of wetlands. Alternative 2 impacted
504 feet of stream and 0.6 acres of wetlands.
1.3.2 Proposed compensatory mitigation: Due to the 308 feet of permanent stream
function loss due to the installation of a culvert, 618 feet of warm water stream
credits will be purchased from ***. 20,038 total NRRB impact *** square feet of
Neuse River riparian buffer credits will also be purchased. ** square feet of Zone
1 and ** square feet of Zone 2. ** 0.2 AC impact of City of Durham 100 foot
stream buffer
1.4 Existing conditions and any applicable project history: Add Affected Environment
/ Environmental Consequences section of EA when completed.

1.5 Permit Authority: Section 404 of the Clean Water Act (33 USC 1344).
2.0 Scope of review for National Environmental Policy Act (i.e. scope of
analysis), Section 7 of the Endangered Species Act (i.e. action area), and
Section 106 of the National Historic Preservation Act (i.e. permit area)
2.1 Determination of scope of analysis for National Environmental Policy Act (NEPA):
The scope of analysis includes the specific activity requiring a Department of the
Army permit. Other portions of the entire project are included because the Corps
does have sufficient control and responsibility to warrant federal review.
Final description of scope of analysis: Access to the site from North Roxboro
Road is required for the site to be feasible. The access will impact 308 feet of
stream. Without the stream impacts, the site could not be constructed.
2.2 Determination of the "Corps action area" for Section 7 of the Endangered
Species Act (ESA): The Corps action area is the entire area that will be impacted
by construction activities (limits of disturbance). The limits of disturbance (LOD)
was selected as the action area because the site could not be developed without
the stream impacts. The site development is dependent on the stream impacts.
2.3 Determination of permit area for Section 106 of the National Historic Preservation
Act (NHPA):
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: The final permit area is the entire area that
will be impacted by construction activities (limits of disturbance). The limits of
disturbance (LOD) was selected as the permit area because the site could not be
developed without the stream impacts. The site development is dependent on the
stream impacts.
3.0 Purpose and Need
3.1 Purpose and need for the project as provided by the applicant and reviewed by
the Corps: The purpose of the proposed project is to construct a new high school
to replace the existing high school, which is in need of significant repairs with a
new facility that meets the Durham Public School (DPS) high school program as
Page 2 of 28
CE SAW -District abbreviation (e.g. RD, O-R) (File Number, SAW 2019-01814)
well as future student capacity needs.
3.2 Basic project purpose, as determined by the Corps: Select N/A or basic purpose
here.
3.3 Water dependency determination: The activity does require access or proximity
to or siting within a special aquatic site to fulfill its basic purpose. Therefore, the
activity is water dependent. Stream impacts result from construction of the
access road. The stream impacts are unavoidable and necessary in order to
meet public safety standards under the City of Durham and NCDOT code and
design requirements which require the high school access road from N. Roxboro
Street to align with Wellington Drive.
3.4 Overall project purpose, as determined by the Corps: Describe here.

5.0 Alternatives Analysis (33 CFR Part 325 Appendix B(7), 40 CFR 230.5(c) and
40 CFR 1502.14). An evaluation of alternatives is required under NEPA for all
jurisdictional activities. An evaluation of alternatives is required under the
Section 404(b) (1) Guidelines for projects that include the discharge of dredged
or fill material. NEPA requires discussion of a reasonable range of alternatives,
including the no action alternative, and the effects of those alternatives; under the
Guidelines, practicability of alternatives is taken into consideration and no
alternative may be permitted if there is a less environmentally damaging
practicable alternative.
5.1 Site selection/screening criteria: In order to be practicable, an alternative must
be available, achieve the overall project purpose (as defined by the Corps), and
be feasible when considering cost, logistics and existing technology.
Criteria for evaluating alternatives as evaluated and determined by the Corps:
Uescnae evaluation cntena nel,
5.2 Description of alternatives
5.2.1 No action alternative: The option to leave the school where it is without building a
new school or associated facilities was not evaluated in detail. It was determined
that the existing location of the school is inadequate due to soil conditions and
space constraints, and that without expanding the current school building and
facilities, the goals of the school program cannot be reached.
5.2.2 Off -site alternatives
Page 4 of 28
CE SAW -District abbreviation (e.g. RD, O-R) (File Number, SAW 2019-01814)
Off -site alternative 1: Numerous sites were evaluated and rejected for various
reason. The attached table presents the results of the off -site evaluations.
Off -site alternative 2: Description of off -site alternative 2
5.2.3 On -site alternatives
On -site alternative 1 (applicant's preferred alternative): on -site alternative 3 is the
Preferred Alternative for the purpose of this document.
On -site alternative 1: In this alternative, the entirety of the high school program
would be located between the two stream and wetland systems on the property.
This would reduce the development footprint with the goal of reducing site
development costs associated with the grading of the rocky area on the
northwest side of the property. Access to the site would be provided at two drives
along the proposed Hebron Road extension. The loading/unloading area for
students from both bus and parent vehicles would be located centrally at the
main entrance to the building. Student parking would be located west of the main
building. Staff parking would be at the front of the building along the Hebron
Road extension and west of the main entrance. Student and staff parking would
be located and designed so that they would not interfere with loading/unloading
operations. The competition and recreational fields would be located on the north
portion of the site. The track, football field and possible future stadium would be
located east of the building. These fields would be located in close proximity to
the building allowing for ease of daily use by the students. The drive provided
around the building would act as a fire lane which could be gated at both ends to
allow for safe pedestrian use as necessary. Closing the gates would eliminate
pedestrian vehicular conflict as pedestrians would have vehicular -free access to
these areas. On -Site Alternative 1 would result in the placement of stormwater
control measures in Waters of the U.S. and regulated riparian buffers. On -Site
Alternative 1 would also result in significant impacts to the large wetland complex
as well as the perennial stream located along the western boundary of the
property. This would cause considerable loss of hydrological, chemical and
biological connectivity to downstream waters.
On -site alternative 2: ): In this alternative, the majority of the high school program
is located between the two perennial streams and associated riparian buffers on
the property. Similar to the On -Site Alternative 1, the primary school building
would be located between the two stream and wetland systems on the property
site. Athletic facilities such as the football field/stadium and competition field,
however, would be sited west of the perennial stream located in the central
portion of the property. Access to the site would be provided by two drives along
the proposed Hebron Road extension. The loading/unloading areas for students
Page 5 of 28
CE SAW -District abbreviation (e.g. RD, O-R) (File Number, SAW 2019-01814)
from both bus and parent vehicles would be located centrally at the main
entrance to the building. Student and staff parking would be located to the west
of the main building and would not interfere with loading/unloading operations.
The rear of the building would open to green, athletic field, and recreation space.
This would eliminate conflict between pedestrians and vehicles as pedestrians
would not have to cross a drive to obtain access to these areas. On -Site
Alternative 2 would result in considerably less impacts to the large wetland and
stream complex on the eastern boundary of the property. In addition, this
proposed Alternative more closely resembles the ingress and egress
requirements for the school. However, On -Site Alternative 2 would also result in
the placement of stormwater control measures in regulated riparian buffers. The
orientation of the buildings in this alternative was also predicted to impact
stormwater features on the site.
On -site alternative 3 (applicant's preferred alternative): This alternative follows a
very similar configuration as on -site alternative 2, with the majority of the high
school program located between the two stream buffers. The football
field/stadium would be located on the west side of the stream buffer, and the
primary building would be located on the east side of the site. Having the football
field and stadium on the west side of the property was most practical, as fields
will require less grading than a building. Access to the site would be provided by
one drive along the access road to eventually be the Hebron Road extension with
a bridge over the stream from N. Roxboro Street. A second point of access would
be located off North Roxboro Street, 600 feet north of the first access drive. A
third access drive from Old Well Street at the north of the site would allow access
for bus staff only. Parking lot configuration in this option would be the same as in
on -site alternative 2. The main difference is in the configuration of the tennis
fields and baseball diamonds to allow for the multi -purpose field to be located
further west in avoidance of the river buffers on the east side of the site.
Similarly, the orientation of the stadium and competition field on the west side of
the site are shifted slightly from alternative 2, to avoid buffer impacts. As per
requested by the City, the site plan includes a 70-foot wide land reservation for
future right-of-way shall the Hebron Road extension ever be constructed. This
70-foot land reservation would allow for a 3-lane road with bike lanes and
sidewalks on both sides of the road as required for minor thoroughfares in the
City of Durham. A 30-foot wide private drive is being proposed for school use
only, specifically the staff and parent ingress/egress.
5.3 Evaluate alternatives and whether or not each is practicable under the Guidelines
or reasonable under NEPA Based on the decision not to construct the Hebron
Road Extension in addition to the significant proposed impacts to Waters of the
U.S., regulated riparian stream buffers and downstream water
Page 6 of 28
CE SAW- )istrict abbreviation (e.g. RD, O-R) (File Number, SAW 2019-01814)
quality/connectivity that would result from the construction of On -Site Alternative
1, this alternative was determined not to be feasible or practical.
Based on the decision not to construct the Hebron Road Extension in addition to
the significant proposed impacts to regulated riparian stream buffers and
downstream water quality that would result from the construction of On -Site
Alternative 2, this alternative was determined not to be feasible or practical.
5.4 Least environmentally damaging practicable alternative under the 404(b)(1)
Guidelines (if applicable) and the environmentally preferable alternative under
N E PA:
Despite impacts projected to streams, wetlands and river buffers associated with
the stream crossing in on -site Alternative 3, it was determined that these impacts
are unavoidable and necessary in order to meet public safety standards under
the City of Durham and NCDOT code and design requirements. Despite impacts
requiring an IP, on -site Alternative 3 avoided stormwater feature impacts that on -
site Alternative 2 would not, avoided extensive grading that would be required if a
building was located on the northwest side of the site (as in Alternative 2), and
avoided stream impacts that Alternative 1 would have involved. On -Site
Alternative 3 was carried forward as the preferred alternative as it was
determined to be the Least Environmentally Damaging Practicable Alternative
(LEDPA) and was used in further field investigations conducted as part of the
Phase 1 ESA by SEPI, Inc.
6.0 Evaluation for Compliance with the Section 404(b)(1) Guidelines. The
following sequence of evaluation is consistent with 40 CFR 230.5
6.1 Practicable alternatives to the proposed discharge consistent with 40 CFR
230.5(c) are evaluated in Section 5. The statements below summarize the
analysis of alternatives.
In summary, based on the analysis in Section 5.0 above, the no -action
alternative, which would not involve discharge into waters, is not practicable.
For those projects that would discharge into a special aquatic site and are not
water dependent, the applicant has demonstrated there are no practicable
alternatives that do not involve special aquatic sites.
It has been determined that there are no alternatives to the proposed discharge
that would be less environmentally damaging. (Subpart B, 40 CFR 230.10(a)).
The proposed discharge in this evaluation is the practicable alternative with the
least adverse impact on the aquatic ecosystem, and it does not have other
significant environmental consequences.

Bald Eagle
Habitat Description: The bald eagle primarily consists of mature forest in
proximity to large bodies of open water for foraging. Large dominant trees are
utilized for nesting sites, typically within 1.0 mile of open water. Bodies of water
typically need to be at least 2 acres or larger to be able to support a bald eagle
population. A desktop-GIS assessment of the project study area, as well as the
area within a 1 mile radius of the project limits, was performed on May 31, 2019,
using 2010 color aerials. The Eno River is the only water body large enough to
Page 9 of 28
CE SAW- )istrict abbreviation (e.g. RD, O-R) (File Number, SAW 2019-01814)
support foraging habitat within one mile of the project study area and is 0.5 miles
north of the project study area, and Falls Lake is located 5 miles to the east. The
bald eagle survey area designated by U.S. Fish and Wildlife is a 660-foot buffer
around the project study area. Land use within and in the 660 feet surrounding
the project study area is highly urbanized and does not contain water bodies
large enough to support bald eagle habitat. Additionally, a review of the NCNHP
database on May 31, 2019, revealed no known occurrences of this species within
one mile of the project study area. Due to the lack of habitat, known
occurrences, and minimal impact anticipated for this project, it has been
determined that this project will not affect this species.
Biological Conclusion: No Effect
Carolina madtom
Biological Conclusion: No Effect
The Carolina madtom prefers shallow sand-, gravel-, and detritus -bottomed riffles
and runs with little or no current over fine to coarse sand bottom in small to
medium rivers. North Carolina Natural Heritage Program (NCNHP) records
generated on May 23, 2019 document no occurrences of Carolina madtom within
one mile of the project study area. Streams were assessed in study area on June
12, 2019. No suitable habitat was observed during surveys. Streams were
determined to be severely unstable and eroding.
Critical Habitat Carolina madtom
Biological Conclusion: No Effect
USFWS has proposed critical habitat for the Neuse River waterdog within
Durham County. The nearest proposed critical habitat is the Eno River
approximately 3/4 mile downstream of the study area.
Neuse River waterdog
Biological Conclusion: No Effect
The Neuse River waterdog inhabits well oxygenated medium to large rivers and
streams with high water quality. They prefer eddies and backwaters with large
amounts of leaves and woody debris. NCNHP records generated on May 23,
2019 document no occurrences of Neuse River waterdog within one mile of the
project study area. Streams were assessed in study area on June 12, 2019. No
suitable habitat was observed during surveys. Streams were determined to be
severely unstable and eroding.
Critical Habitat Neuse River waterdog
Biological Conclusion: No Effect
USFWS has proposed critical habitat for the Neuse River waterdog within
Durham County. The nearest proposed critical habitat is the Eno River
approximately 3/4 mile downstream of the study area.
Page 10 of 28
CE SAW- )istrict abbreviation (e.g. RD, O-R) (File Number, SAW 2019-01814)
Atlantic pigtoe
Biological Conclusion: No Effect
The Atlantic pigtoe requires fast flowing, well oxygenated high quality
riverine/large creek and is restricted to fairly pristine habitats. It is typically found
in headwaters or rural watersheds. The preferred habitat of the Atlantic pigtoe is
coarse sand and gravel at the downstream edge of riffles. NCNHP records
generated on May 23, 2019 document no occurrences of Atlantic pigtoe within
one mile of the project study area. Streams were assessed in study area on June
12, 2019. No suitable habitat was observed during surveys. Streams were
determined to be severely unstable and eroding.
Critical Habitat Atlantic pigtoe
Biological Conclusion: No Effect
USFWS has proposed critical habitat for the Atlantic pigtoe within Durham
County. The nearest proposed critical habitat is the Eno River approximately 3/4
mile downstream of the study area.
Dwarf wedgemussel
Biological Conclusion: No Effect
In North Carolina, the dwarf wedgemussel is known from the Neuse and Tar
River drainages. The mussel inhabits creek and river areas with a slow to
moderate current and sand, gravel, or firm silt bottoms. Water in these areas
must be well oxygenated. Stream banks in these areas are generally stable with
extensive root systems holding soils in place. NCNHP records generated on May
23, 2019 document no occurrences of dwarf wedgemussel within one mile of the
project study area. Streams were assessed in study area on June 12, 2019. No
suitable habitat was observed during surveys. Streams were determined to be
severely unstable and eroding.
Michaux's sumac
Habitat Description: Michaux's sumac most commonly grows in highway rights -
of way, roadsides, or on the edges of artificially maintained clearings. NCNHP
records generated on May 23, 2019 document no occurrences of Michaux's
sumac within one mile of the project study area. Suitable habitat consisting of
maintain rights -of way were surveyed on May 21, 2019 and no individuals were
found.
Biological Conclusion: No Effect
Smooth coneflower
Habitat Description: Optimal habitat for the smooth coneflower consists of
periodically disturbed woods/roadside areas with abundant sunlight available.
Habitat for smooth coneflower does exist within the project study area. NCNHP
Page 11 of 28
CE SAW -District abbreviation (e.g. RD, O-R) (File Number, SAW 2019-01814)
records generated on May 23, 2018 documented an occurrence of the smooth
coneflower within 1 mile of the project study area. Surveys for smooth coneflower
were performed within the study area on May 21, 2019 and no individuals were
found.
Biological Conclusion: May Affect — Not Likely to Adversely Affect
There will be a minor short-term effect to fish, crustaceans, mollusk, other
aquatic organisms and other wildlife during construction of the culverts and other
construction activities. The effect is considered minor and short term because the
culverts will be buried per NCDEQ requirements.

The preferred alternative will avoid all wetland impacts.
There will be a minor short-term effect to riffle and pool complexes during
construction of the culverts. The effect is considered minor and short term
because the effect will occur only during construction and the culverts will be
buried per NCDEQ requirements.

Discussion: SEPI, Inc. conducted a Phase I ESA for the property located at 4622
North Roxboro Street and 4804 North Roxboro Street (Target Property) in
Durham, North Carolina. The Phase I ESA was performed in accordance with the
scope and limitations as outlined in American Society of Testing and Materials
(ASTM) Standard Practice Designation E 1527-13 and presented in the May 15,
2019 proposal. The assessment did not revealed evidence of RECs, HRECs, de
minimis conditions, or other environmental concerns on the Target Property.
It has been determined that testing is not required because the proposed
material is not likely to be a carrier of contaminants because it is comprised of
sand, gravel or other naturally occurring inert material.
6.6 Evaluation and testing (Subpart G, 40 CFR 230-61):
Discussion: The Phase I ESA did not revealed evidence of RECs, HRECs, de
minimis conditions, or other environmental concerns on the Target Property.
Therefore, no testing was performed.
6.7 Actions to minimize adverse impacts (Subpart H). The following actions, as
appropriate, have been taken through application of 40 CFR 230.70-230.77 to
ensure minimal adverse effects of the proposed discharge. See Table 6:
Table 6 — Actions to Ensure Adverse Effects are Minimized
Actions concerning the location of the discharge
X
Actions concerning the material to be discharged
X
Actions controlling the material after discharge
X
Actions affecting the method of dispersion
X

X
Actions affecting human use
X
Discussion: The location of the discharge will be the minimum required to
complete the project. As presented above several alternatives were evaluated.
The preferred alternative minimizes the discharge required. All required
engineering and construction practices (including erosion and sedimentation
control) were and will be followed to minimize effects to plants animals and
human uses.

Discussion: There will be a minor short term effect to suspended
particulates/turbidity and aquatic ecosystem and organisms during construction
of the culverts. The effect is considered minor and short term because
construction will follow the approved erosion and sediment control plan and the
culverts will be buried per NCDEQ requirements.
There will be no effects from contaminates. The Phase 1 ESA did not identify any
potential contaminants and construction activities will the approved erosion and
sediment control plan.
There will be no secondary effects on the aquatic ecosystem. Stormwater control
measures are included in the design to control the discharge of stormwater form
the completed site to the aquatic ecosystem.
6.9 Findings of compliance or non-compliance with the restrictions on discharges (40
CFR 230.10(a-d) and 230.12). Based on the information above, including the
factual determinations, the proposed discharge has been evaluated to determine
whether any of the restrictions on discharge would occur. See Table 8:

7.1.1 Climate Change. The proposed activities within the Corps federal control and
responsibility likely will result in a negligible release of greenhouse gases into the
atmosphere when compared to global greenhouse gas emissions. Greenhouse
gas emissions have been shown to contribute to climate change. Aquatic
resources can be sources and/or sinks of greenhouse gases. For instance,
some aquatic resources sequester carbon dioxide whereas others release
methane; therefore, authorized impacts to aquatic resources can result in either
an increase or decrease in atmospheric greenhouse gas. These impacts are
considered de minimis and are negated through compensatory mitigation.
Greenhouse gas emissions associated with the Corps federal action may also
occur from the combustion of fossil fuels associated with the operation of
construction equipment, increases in traffic, etc. The Corps has no authority to
regulate emissions that result from the combustion of fossil fuels. These are
subject to federal regulations under the Clean Air Act and/or the Corporate
Average Fuel Economy (CAFE) Program. Greenhouse gas emissions from the
Corps action have been weighed against national goals of energy independence,
national security, and economic development and determined not contrary to the
public interest. ADD, if determined appropriate, otherwise deletE The applicant
Page 18 of 28
CE SAW- )istrict abbreviation (e.g. RD, O-R) (File Number, SAW 2019-01814)
voluntarily provided the Corps with an analysis of greenhouse gas emissions that
they produced for other local, state, and/or federal requirements, entitled
[INSERT NAME], dated [Insert DATE]. The portions of that document pertaining
to the actions within the Corps federal control and responsibility are incorporated
by reference.
7.2 The relative extent of the public and private need for the proposed structure or
work:
There is a public need for the new high school. The existing high school, which is
in need of significant repairs with a new facility that meets the Durham Public
School (DPS) high school program as well as future student capacity needs.
7.3 If there are unresolved conflicts as to resource use, explain how the practicability
of using reasonable alternative locations and methods to accomplish the
objective of the proposed structure or work was considered.
Discussion: There are no unresolved conflicts as to resource use. Initial public
comment was solicited from the residents surrounding the project site. The
comment period ended August 1, 2020.
7.4 The extent and permanence of the beneficial and/or detrimental effects that the
proposed work is likely to have on the public and private use to which the area is
suited:
Detrimental effects are expected to be minimal and temporary.
Beneficial effects are expected to be more than minimal and permanent.
Detrimentai errects to public ana private uses will be minimal and temporary only
associated with construction activities.
Beneficial effects to public and private uses will be more than minimal and
permanent. The project will result in a new state of the art public high school.

9.0 Consideration of Cumulative Impacts
(40 CFR 230.11(g) and 40 CFR 1508.7, RGL 84-9) Cumulative impact is the
impact on the environment which results from the incremental impact of the
action when added to other past, present, and reasonably foreseeable future
actions regardless of what agency (Federal or non -Federal) or person
undertakes such other actions. Cumulative impacts can result from individually
minor direct and indirect but collectively significant actions taking place over a
Page 21 of 28
CE SAW- )istrict abbreviation (e.g. RD, O-R) (File Number, SAW 2019-01814)
period of time. A cumulative effects assessment should consider how the direct
and indirect environmental effects caused by the proposed activity requiring DA
authorization (i.e., the incremental impact of the action) contribute to cumulative
effects, and whether that incremental contribution is significant or not. .
9.1 Identify/describe the direct and indirect effects caused by the proposed activity:
A review of potential cumulative impacts to Waters of the U.S. from the
construction of the Proposed Northern High School, indicates that the proposed
development would not have significant adverse effects on the aquatic
ecosystem. The rationale for this presumption is based on the following
considerations:
• All stormwater devices will be located outside of jurisdictional streams and
wetlands and protected stream buffers.
• The proposed stormwater management systems, including numerous stormwater
treatment and retainage structures, are planned to capture and treat all
stormwater on -site before discharge to surface waters.
• Adequate Erosion & Sediment Control systems will be in place and maintained
during construction.
• No untreated stormwater or construction runoff will be discharged into Waters of
the U.S. (wetlands and streams); therefore, the water quality of downstream
receiving waters, specifically the Eno River, will not be impaired.
The proposed impacts to the Waters of the U.S. from construction of the
proposed Northern High School should have no cumulative effects on the quality
of other jurisdictional waters occurring beyond the Preferred Alternative Site. This
presumption is based on the review of environmental documentation regarding
known current and past federal and non-federal actions in the area. Projects in
the planning phase were also considered, including reasonably foreseeable
(rather than speculative) actions that have the potential to interact with the
proposed action. To have reasonable assurances that there would be cumulative
effects to projects when considered together or incrementally, the projects
needed to occur within similar time frames and within a geographic area,
coinciding with the proposed action.
9.2 The geographic scope for the cumulative effects assessment is:
Describe here.
9.3 The temporal scope of this assessment covers: Describe here.
9.4 Describe the affected environment: Describe here.
9.5 Determine the environmental consequences: )escribe here.
Page 22 of 28
CE SAW- )istrict abbreviation (e.g. RD, O-R) (File Number, SAW 2019-01814)
9.6 Discuss any mitigation to avoid, minimize or compensate for cumulative effects:
Provide discussion here.
9.7 Conclusions regarding cumulative impacts:
When considering the overall impacts that will result from the proposed activity,
in relation to the overall impacts from past, present, and reasonably foreseeable
future activities, the incremental contribution of the proposed activity to
cumulative impacts in the area described in section 9.2, are not considered to be
significant . Compensatory mitigation will be required to help offset the impacts
to eliminate or minimize the proposed activity's incremental contribution to
cumulative effects within the geographic area described in Section 9.2.
Mitigation required for the proposed activity is discussed in Section 8.0.

12.0 Findings and Determinations
Page 26 of 28
CE SAW -District abbreviation (e.g. RD, O-R) (File Number, SAW 2019-01814)
12.1 Section 176(c) of the Clean Air Act General Conformity Rule Review: The
proposed permit action has been analyzed for conformity applicability pursuant to
regulations implementing Section 176(c) of the Clean Air Act. It has been
determined that the activities proposed under this permit will not exceed
deminimis levels of direct or indirect emissions of a criteria pollutant or its
precursors and are exempted by 40 CFR Part 93.153. Any later indirect
emissions are generally not within the Corps' continuing program responsibility
and generally cannot be practicably controlled by the Corps. For these reasons
a conformity determination is not required for this permit action.
12.2 Presidential Executive Orders (EO):
12.2.1 EO 13175, Consultation with Indian Tribes, Alaska Natives, and Native
Hawaiians: This action has no substantial effect on one or more Indian tribes,
Alaska or Hawaiian natives.
12.2.2 EO 11988, Floodplain Management: This action is not located in a floodplain.
12.2.3 EO 12898, Environmental Justice: The Corps has determined that the proposed
project would not use methods or practices that discriminate on the basis of race,
color or national origin nor would it have a disproportionate effect on minority or
low-income communities.
12.2.4 EO 13112, Invasive Species: (here are no invasive species issues involved in
this proposed projec
12.2.5 EO 13212 and EO 13302, Energy Supply and Availability: The proposal is not
one that will increase the production, transmission, or conservation of energy, or
strengthen pipeline safety.
12.3 Findings of No Significant Impact: Having reviewed the information provided by
the applicant and all interested parties and an assessment of the environmental
impacts, I find that this permit action will not have a significant impact on the
quality of the human environment. Therefore, an environmental impact
statement will not be required.
12.4 Compliance with the Section 404(b)(1) Guidelines: Having completed the
evaluation above, I have determined that the proposed discharge complies with
the Guidelines
12.5 Public interest determination: Having reviewed and considered the information
above, I find that the proposed project is not contrary to the public interest.
