BIOLOGICAL RESOURCES ASSESSMENT AND WETLAND DETERMINATION
FOR THE TEN TURRI SOLAR FARM, 870 OROVILLE-CHICO HIGHWAY,
DURHAM, BUTTE COUNTY, CALIFORNIA. MHBA FILE 0106-2025-3977.
1.0 INTRODUCTION
On January 9, 2025 Marcus H. Bole & Associates performed a Biological Resources Assessment and
Wetland Determination for a Study Area located at 870 Oroville-Chico Highway for the proposed Ten
Turri Solar Farm property. The Study Area is defined as the ±31.94-acre Butte County APN 040-490-002
and a 500-foot buffer surrounding the parcel. (See Appendix A, Figure 1). The Study Area is located on
the U.S. Geological survey (USGS) Hamlin Canyon 7.5-minute topographic quadrangle, Township 21
North, Range 2 East. The center of the Study Area is approximately 39.650764N, -121.728895W. The
terrain elevation within the Study Area is approximately 180 feet above mean sea level (msl) in relatively
flat terrain. The Study Area is undeveloped agricultural land that formerly supported rice farming, dry
cereal farming and cattle grazing. Non-native grasses characterize the vegetative community. During
onsite surveys, approximately 0.93-acres of an ephemeral drainage swale was identified along the
northern boundary of the Study Area with a flow direction to the west. Additionally, approximately 0.25-
acres of roadside ditch was found along Highway 99. The seasonal drainage swale and roadside ditch
carry sheet flow precipitation from the property and from the eastern side of Highway 99. Surveys were
conducted outside the normal blooming cycle for all plants of concern; therefore, the surveys focused on
the presence of micro-habitat to support special status plant species (wetlands, vernal pools, etc.).
Additional surveys will be required during the spring (May – June) of 2025 to confirm findings.
Appropriate setbacks from the drainage swale and the Highway 99 roadside ditch should be determined
and coordinated with Butte County Planning prior to construction. In accordance with United States
Army Corps of Engineers (USACE) guidance, ephemeral drainages do not meet the definition of
jurisdictional Waters of the United States (WOUS). Likewise, roadside ditches are not considered
jurisdictional Waters of the United States.

2.0 DESCRIPTION OF PROJECT
Tenter Enterprises (owner) proposes to install approximately 6,132 Canadian Solar Modules within
approximately 11.5-acres of the 31.94-acre property (see Attachment A, Figure 3). Storm drainage runoff
will be collected in an underground collection system and conveyed to the existing drain along the north
side of the project. Increased runoff due to the development of the lots will be mitigated through the use
of on-site detention/retention basins.
3.0 METHODOLOGY
Field surveys of biological resources included an inventory of plants and wildlife observed in the Study
Area, habitat assessments for special status species, and a determination of wetland habitats within the
Study Area. Biological and botanical surveys were conducted based on the California Department of Fish
and Wildlife’s (CDFW) Natural Diversity Database (CNDDB, January 2025), the United States Fish &
Wildlife Service’s (USFWS) IPaC Resource List, and the California Native Plant Society's (CNPS) list of
rare and endangered plants. All species lists were derived from the United States Geological Survey
(USGS) Hamlin Canyon 7.5 minute quadrangle and eight surrounding quadrangles. Based on the results
of the species lists, appropriate biological and botanical surveys were conducted. Species habitat surveys
were conducted during January 2025, by Marcus H. Bole & Associates (MHBA) senior wildlife biologist
Marcus H. Bole. The species habitat surveys were conducted by walking all areas of the Study Area (and
surrounding 500 foot buffer) and evaluating potential habitat for special-status species based on
vegetation composition and structure, presence of predatory species, microclimate and available resources
(e.g. prey items, nesting burrows, etc.). A general botanical survey and habitat evaluation for rare plant
botanical species was conducted during January 2025 by MHBA's senior botanist Charlene J. Bole. The
general botanical survey and habitat evaluation for rare plant botanical species was conducted by walking
all areas of the Study Area while taking inventory of general botanical species and searching for special-
status plant species and their habitats. A determination of Waters of the U.S. was conducted on January
9, 2025 by Marcus H. Bole, Senior Wetland Scientist and was conducted under the guidelines of the
Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Arid West Region (2008).
4.0 Regulatory Requirements
The following describes federal and state environmental laws and policies that are relevant to the
California Environmental Quality Act (CEQA) review process.

Federal Endangered Species Act
The United States Congress passed the Federal Endangered Species Act (ESA) in 1973 to protect species
that are endangered or threatened with extinction. The ESA is intended to operate in conjunction with the
National Environmental Policy Act (NEPA) to help protect the ecosystems upon which endangered and
threatened species depend. The ESA makes it unlawful to “take” a listed animal without a permit. Take is
defined as “to harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect or attempt to engage
in any such conduct”. Through regulations, the term “harm” is defined as “an act which actually kills or
injures wildlife". Such an act may include significant habitat modification or degradation where it actually
kills or injures wildlife by significantly impairing essential behavioral patterns, including breeding,
feeding, or sheltering.
Migratory Bird Treaty Act
The Migratory Bird Treaty Act (MBTA) (16 USC §703) prohibits the killing of migratory birds or the
destruction of their occupied nests and eggs except in accordance with regulations prescribed by the
USFWS. The bird species covered by the MBTA includes nearly all of those that breed in North America,
excluding introduced (i.e. exotic) species (50 Code of Federal Regulations §10.13). Activities that involve
the removal of vegetation including trees, shrubs, grasses, and forbs or ground disturbance has the
potential to affect bird species protected by the MBTA.
Waters of the United States, Clean Water Act, Section 404
The US Army Corps of Engineers (USACE) and the U.S. Environmental Protection Agency (EPA)
regulate the discharge of dredged or fill material into jurisdictional waters of the United States, under the
Clean Water Act (§404). The term “waters of the United States” is an encompassing term that includes
“wetlands” and “other waters”. Wetlands have been defined for regulatory purposes as follows: “those
areas that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to
support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for
life in saturated soil conditions (33 CFR 328.3, 40 CFR 230.3). Wetlands generally include swamps,
marshes, bogs, and similar areas.” Other Waters of the United States (OWUS) are seasonal or perennial
water bodies, including lakes, stream channels, drainages, ponds, and other surface water features, that
exhibit an ordinary high-water mark but lack positive indicators for one or more of the three wetland
parameters (i.e., hydrophytic vegetation, hydric soil, and wetland hydrology) (33 CFR 328.4). In
accordance with United States Army Corps of Engineers (USACE) guidance, ephemeral drainage swales
do not meet the definition of jurisdictional Waters of the United States.1
Clean Water Act, Section 401
The Clean Water Act (§401) requires water quality certification and authorization for placement of
dredged or fill material in wetlands and OWUS. In accordance with the Clean Water Act (§401), criteria
for allowable discharges into surface waters have been developed by the State Water Resources Control
Board, Division of Water Quality. The resulting requirements are used as criteria in granting National
Pollutant Discharge Elimination System (NPDES) permits or waivers, which are obtained through the
Regional Water Quality Control Board (RWQCB) per the Clean Water Act (§401). Any activity or
facility that will discharge waste (such as soils from construction) into surface waters, or from which
waste may be discharged, must obtain an NPDES permit or waiver from the RWQCB. The RWQCB

evaluates an NPDES permit application to determine whether the proposed discharge is consistent with
the adopted water quality objectives of the basin plan.
Waters of the State of California
In accordance with the Porter-Cologne Water Quality Control Act (Water Code, § 13000 et seq.) the State
Water Resources Control Board (SWRCB) and the Regional Water Quality Control Boards (RWQCBs)
(Water Boards) are authorized to regulate discharges of waste, which includes discharges of dredged or
fill material, that may affect the quality of waters of the state. Procedures for the discharge of dredged or
fill material to waters of the state conform to Executive Order W-59-93, the procedures ensure that the
Water Boards’ regulation of dredge or fill activities will be conducted in a manner “to ensure no overall
net loss and long-term gain in quantity, quality, and permanence of wetlands acreage and values...” The
Water Boards define an area as wetland as follows: An area is wetland if, under normal circumstances,
(1) the area has continuous or recurrent saturation of the upper substrate caused by groundwater, or
shallow surface water, or both; (2) the duration of such saturation is sufficient to cause anaerobic
conditions in the upper substrate; and (3) the area’s vegetation is dominated by hydrophytes or the area
lacks vegetation. Changes to the federal Navigable Waters Protection Rule went into effect in 2020,
finalizing a revised definition of “waters of the United States” under the federal Clean Water Act (CWA)
and significantly decreased the number of waters that fall under federal jurisdiction. Ephemeral features
that only flow as a direct result of precipitation are no longer considered a water of the United States. The
California State Water Resources Control Board (SWRCB) adopted the State Wetland Definition and
Procedures for Discharges of Dredged or Fill Material to Waters of the State (Procedures), which went
into effect on May 28, 2020. The SWRCB considers all current and historic waters of the United States,
including those that fell under a previous regulatory definition of waters of the United States as waters of
the state. An example of a historic water of the United States that no longer falls under federal
jurisdiction but still falls under the jurisdiction of the SWRCB and RWQCBs are ephemeral features (like
drainage swales). The new requirement is to obtain a Waste Discharge Requirement (WDR) pursuant to
the Porter-Cologne Water Quality Control Act.
California Endangered Species Act
The California Endangered Species Act (CESA) is similar to the federal ESA, but pertains to state-listed
endangered and threatened species. The CESA requires state agencies to consult with the CDFW when
preparing documents to comply with the CEQA. The purpose is to ensure that the actions of the lead
agency do not jeopardize the continued existence of a listed species or result in the destruction, or adverse
modification of habitat essential to the continued existence of those species. In addition to formal listing
under the federal and state endangered species acts, “species of special concern” receive consideration by
CDFW. Species of special concern are those whose numbers, reproductive success, or habitat may be
threatened.
California Fish and Wildlife Code
The California Fish and Game Code (CFGC) (§3503.5) states that it is “unlawful to take, possess, or
destroy any birds in the order Falconiformes (hawks, eagles, and falcons) or Strigiformes (all owls except
barn owls) or to take, possess, or destroy the nest or eggs of any such bird except as otherwise provided
by this code or any regulation adopted pursuant thereto”. Take includes the disturbance of an active nest
resulting in the abandonment or loss of young. The CFGC (§3503) also states that “it is unlawful to take,
possess, or needlessly destroy the nest or eggs of any bird, except as otherwise provided by this code or
any regulation made pursuant thereto”.

Rare and Endangered Plants
The California Native Plant Society is not a regulatory agency. However, the CNPS maintains a list of
plant species native to California with low population numbers, limited distribution, or otherwise
threatened with extinction. This information is published in the Inventory of Rare and Endangered
Vascular Plants of California. Potential impacts to populations of CNPS-ranked plants receive
consideration under CEQA review. The CNPS California Rare Plant Rank (CRPR) categorizes plants as
the following:
Rank 1A: Plants presumed extinct in California;
Rank 1B: Plants rare, threatened, or endangered in California or elsewhere;
Rank 2: Plants rare, threatened, or endangered in California, but more numerous elsewhere;
Rank 3: Plants about which we need more information; and
Rank 4: Plants of limited distribution.
The California Native Plant Protection Act (CFGC §1900-1913) prohibits the taking, possessing, or sale
within the state of any plants with a state designation of rare, threatened, or endangered as defined by
CDFW. An exception to this prohibition allows landowners, under specific circumstances, to take listed
plant species, provided that the owners first notify CDFW and give the agency at least 10 days to retrieve
(and presumably replant) the plants before they are destroyed. Fish and Wildlife Code §1913 exempts
from the ‘take’ prohibition ‘the removal of endangered or rare native plants from a canal, lateral ditch,
building site, or road, or other right of way”.
California Environmental Quality Act Guidelines §15380
Although threatened and endangered species are protected by specific federal and state statutes, CEQA
Guidelines §15380(d) provides that a species not listed on the federal or state list of protected species may
be considered rare or endangered if the species can be shown to meet certain specified criteria. These
criteria have been modeled based on the definition in the ESA and the section of the CFGC dealing with
rare, threatened, and endangered plants and animals. The CEQA Guidelines (§15380) allows a public
agency to undertake a review to determine if a significant effect on species that have not yet been listed
by either the USFWS or CDFW (e.g. candidate species, species of concern) would occur.
5.0 SETTING
Regionally, the Study Area is located within the northern California central valley, within the city of
Durham, California. Located in rolling to flat foothill terrain, with and elevation of 180 feet above sea
level, the mean annual precipitation is approximately 33.68 inches as recorded at the Chico Municipal
Airport. Mean monthly temperature ranges from 40 to 98 degrees Fahrenheit. The vegetative community
descriptions and nomenclature described in this section generally follow the classification of disturbed
(agricultural grading for rice farming) non-native grasslands. The major hydrological features within the
Study Area are the ephemeral drainage swale along the northern boundary of the property and the
roadside ditch along Highway 99. There are no perennial streams, lakes or ponds within the Study Area.
6.0 RESULTS
6.1 Description of the Existing Biological and Physical Conditions
The Study Area is located in the City of Durham, southwest of Highway 99 and northeast of the Oroville-
Biological Resource Assessment and Wetland Determination 870 Oroville-Chico Highway, Durham CA

Chico Highway, Butte County, California. The following describes the biological and physical conditions
within the property and within the surrounding area.
6.1.1 Study Area
The Study Area includes Butte County APN 040-490-002 and a 500-buffer surrounding the parcel.
The flat to rolling foothill environments surrounding the Study Area are characterized by agricultural and
grazing lands with seasonal and ephemeral drainages. A grove of medium diameter eucalyptus
(Eucalyptus ssp.) trees form the southeast boundary of the Study Area. The ephemeral drainage swale
along the northern boundary of the Study Area supports a sparse amount of seasonal wetland grasses.
6.1.2 Physical & Biological Conditions
Vegetation within the Study Area consists of a mix of native and non-native grasses and eucalyptus trees.
The ephemeral drainage supports a sparse amount of seasonal wetland grasses. Surveys were conducted
following several inches of rain that occurred during the November – December time period. The
ephemeral drainage had no flows; however, recent rain water has ponded in several areas. Additional
surveys should be conducted during the spring blooming cycle time period.
Non-native grasslands
Historical aerials (See Appendix D) show the Study Area as relatively well vegetated with native and
non-native grasses characteristic of former rice fields that have been out of production for several years.
Non-native grasses and forbs typically occur on soils consisting of fine-textured loams or clays that are
somewhat poorly drained. This vegetation type is dominated by grasses including wild oats (Avena
barbata), Mediterranean barley (Hordeum marinum), and weedy annuals and perennial forbs, primarily of
Mediterranean origin, that have replaced native grasses as a result of past disturbances including leveling
for rice production. Within the Study Area a diverse weedy flora is present consisting of wild oats, filaree
(Erodium cicutarium), yellow star thistle (Centaurea solstitialis), field bindweed (Convolvulus arvensis),
fiddle dock (Rumex pulcher), medusahead (Elymus caput-medusae), radish (Raphanus raphanistrum),
Italian ryegrass (Festuca perenne), trefoil (Lotus corniculatus), ripgut brome, Bromus diandrus, brome
fescue, Vulpia bromoides, yellow hawkweed, Pilosella caespitosa, cat’s ear, Hypochaeris radicata, and
sow thistle, Sonchus ssp., among others. Medium diameter eucalyptus trees form the southeast boundary
of the Study Area.
Native and introduced wildlife species are tolerant of human activities in non-native grassland land
habitats. Such areas provide habitat for local wildlife species. Common birds such as the northern
mockingbird (Mimus polyglottos), California scrub- jay (Aphelocoma californica), European starling
(Sturnus vulgaris), and mourning dove (Zenaida macroura) were observed foraging in the Study Area.
Two raptors, an American kestrel (Falco sparverius) and a red-shouldered hawk (Buteo lineatus) were
observed overflying the site. Mammals such as raccoon (Procyon lotor), striped skunk (Mephitis
mephitis), and black-tailed jackrabbit (Lepus californicus), are common in non-native grasslands.
6.2 Regional Species and Habitats of Concern
The following table is a list of species that have the potential to occur within the Study Area and is
composed of special-status species within the Hamlin Canyon and adjacent eight 7.5 minute quadrangles.

Migratory Birds
Nesting birds are protected under the MBTA (16 USC 703) and the CFWC (3503). The MBTA (16 USC
§703) prohibits the killing of migratory birds or the destruction of their occupied nests and eggs except in
accordance with regulations prescribed by the USFWS. The bird species covered by the MBTA includes
nearly all of those that breed in North America, excluding introduced (i.e. exotic) species (50 Code of
Federal Regulations §10.13). Activities that involve the removal of vegetation including trees, shrubs,
grasses, and forbs or ground disturbance has the potential to affect bird species protected by the MBTA.
The CFWC (§3503.5) states that it is “unlawful to take, possess, or destroy any birds in the order
Falconiformes (hawks, eagles, and falcons) or Strigiformes (all owls except barn owls) or to take, possess,
or destroy the nest or eggs of any such bird except as otherwise provided by this code or any regulation
adopted pursuant thereto”. Take includes the disturbance of an active nest resulting in the abandonment or
loss of young. The CFWC (§3503) also states that “it is unlawful to take, possess, or needlessly destroy
the nest or eggs of any bird, except as otherwise provided by this code or any regulation made pursuant
thereto”.
Survey Results
During the migratory bird and raptor survey conducted during January 2025, there were no observed nests
within the Study Area. Surveys were conducted outside the nesting season (bird nesting season spans
from February 1 to August 31). Spring follow up surveys will be required, additionally if onsite
disturbances are anticipated during the normal nesting season (February 1 to August 31), preconstruction
nesting surveys will be required a minimum of 30 day prior to ground disturbances..
Mitigation
Based on suitable nesting habitat and historical CNDDB records within a five mile radius of the Study
Area, there is potential nesting opportunities for resident and migratory bird species on or within 500 feet
of the project area. Spring surveys will be required and preconstruction nesting bird surveys will be
required if disturbances are anticipated during the normal nesting season (February 1 – August 31).

7.0 RESULTS: PERMITS AND TECHNICAL STUDIES FOR SPECIAL LAWS OR
CONDITIONS
7.1 Federal Endangered Species Act Summary
The USFWS was contacted during January 2025 for a list of endangered, threatened, sensitive and rare
species, and their habitats within the Study Area. The list was derived from special-status species that
occur or have the potential to occur within the USGS Hamlin Canyon and eight surrounding 7.5"
Quadrangles. The list was referenced to determine appropriate biological and botanical surveys and
potential species occurrence within the Study Area.
7.2 Essential Fish Habitat Summary
Essential fish habitat (EFH) means those waters and substrate necessary to fish for spawning, breeding,
feeding, or growth to maturity (Magnuson-Stevens Fishery Conservation and Management Act (MSA)
§3). There is no habitat within the Study Area that provides "waters and substrate necessary to fish for
spawning, breeding, feeding, or growth to maturity," or special-status fish species managed under a
fishery council (i.e. chinook and Coho). Therefore there is no EFH or the need for federal fisheries

The CDFW was consulted during January 2025 for a list of endangered, threatened, sensitive and rare
species, and their habitats within the Study Area. The list was derived from special-status species that
occur or have the potential to occur within the USGS Hamlin Canyon and eight surrounding 7.5"
Quadrangles. The list was referenced to determine appropriate biological and botanical surveys and
potential species occurrence within the Study Area.
7.4 Wetlands and Others Water Summary
MHBA conducted a Determination of Waters of the U.S. within the Study Area. Surveys were conducted
during January 2025 by MHBA's Marcus H. Bole. The surveys involved an examination of botanical
resources, soils, hydrological features, and determination of wetland characteristics based on the United
States Army Corps of Engineers Wetlands Delineation Manual (1987); the Regional Supplement to the
Corps of Engineers Wetland Delineation Manual: Arid West Region (2008); the U.S. Army Corps of

Engineers Jurisdictional Determination Form Instructional Guidebook (2007); the U.S. Army Corps of
Engineers Ordinary High Flows and the Stage-Discharge Relationship in the Arid West Region (2011);
and the U.S. Army Corps of Engineers Field Guide to the Identification of the Ordinary High Water Mark
(OHWM) in the Arid West Region of the Western United States (2008).
7.5 Determination of Waters of the United States
The intent of this determination is to identify wetlands and “Other Waters of the United States” that are
present within the Study Area that could fall under the regulatory jurisdiction of the U. S. Army Corps of
Engineers (Corps) pursuant to Section 404 of the Clean Water Act. The 1987 Corps of Engineers
Wetlands Delineation Manual identifies several methodologies and combinations of methodologies that
can be utilized in making jurisdictional determinations. Marcus H. Bole & Associates has employed the
Routine On-Site Determination methodology for this study (as supplemented by the Regional Supplement
to the Corps of Engineers Wetland Delineation Manual: Arid West Region, dated September 2008). The
Routine On-Site Determination method uses a three-parameter approach (vegetation, soils and hydrology)
to identify and delineate the boundaries of jurisdictional wetlands. To be considered a wetland, all three
positive wetland parameters must be present. These parameters include (1) a dominance of wetland
vegetation, (2) a presence of hydric soils, and (3) hydrologic conditions that result in periods of
inundation or saturation on the surface from flooding or ponding. Further description of these parameters
is provided below:
1) Vegetation. Wetland vegetation includes those plants that possess physiological traits that allow them
to grow and persist in soils subject to inundation and anaerobic soil conditions. Plant species are
classified according to their probability of being associated with wetlands. Obligate (OBL) wetland plant
species almost always occur in wetlands (more than 99 percent of the time), facultative wetland (FACW)
plant species occur in wetlands most of the time (67 to 99 percent), and facultative (FAC) plant species
have about an equal chance (33 to 66 percent) of occurring in wetlands as in uplands. For this study,
vegetation was considered to meet the vegetation criteria if more than 50% of the vegetative cover was
FAC or wetter. Scattered, sparse seasonal wetland grasses (sedge and dock) were identified within the
ephemeral drainage along the northern boundary of the Study Area.
2) Hydric Soils. Hydric soils are saturated, flooded, or ponded in the upper stratum long enough during
the growing season to develop anaerobic conditions and favor the growth of wetland plants. Hydric soils
include gleyed soils (soils with gray colors), or usually display indicators such as low chroma values,
redoximorphic features, iron, or manganese concretions, or a combination of these indicators. Low
chroma values are generally defined as having a value of 2 or less using the Munsell Soil Notations
(Munsell, 1994). For this study a soil was considered to meet the hydric soil criteria for color if it had a
chroma value of one or a chroma of two with redoximorphic features, or if the soil exhibited iron or
manganese concretions. Redoximorphic features (commonly referred to as mottles) are areas in the soils
that have brighter (higher chroma) or grayer (lower chroma) colors than the soil matrix. Redoximorphic
features are the result of the oxidation and reduction process that occurs under anaerobic conditions. Iron
and manganese concretions form during the oxidation-reduction process, when iron and manganese in
suspension are sometimes segregated as oxides into concretions or soft masses. These accumulations are
usually black or dark brown. Concretions 2 mm in diameter occurring within 7.5 cm of the surface are
evidence that the soil is saturated for long periods near the surface. Onsite soils were identified as
Wafap-Hamsslough (Wafap gravelly loam), 0 to 2 percent slopes. These are not “hydric” soils and except
for the immediate bed of the ephemeral drainage and the Highway 99 roadside ditch, no indication of
hydric soil conditions were observed within or near the Study Area.

3) Hydrology. Wetlands by definition are seasonally inundated or saturated at or near the surface. In
order for an area to have wetland hydrology, it has to be inundated or saturated for 5% of the growing
season (approximately 12 days) (USDA, 1967). Indicators include visual soil saturation, flooding,
watermarks, drainage patterns, encrusted sediment and plant deposits, cryptogrammic lichens, and algal
mats. The ephemeral drainage is fed only through seasonal precipitation. A 50-100 foot setback from the
ephemeral drainage and the Highway 99 roadside ditch should be observed.
Wetland Determination Results
Using the methodologies described in the 1987 Wetland Delineation Manual, Marcus H. Bole &
Associates determined that the Study Area is characterized by approximately 0.93-acres of an ephemeral
drainage and 0.25-acres of a roadside ditch. The project has been designed to avoid impacts to the
ephemeral drainage and roadside ditch.
7.6 Determination of Waters of the State of California
In accordance with the State Wetland Definition and Procedures for Discharges of Dredged or Fill
Material to Waters of the State, the ephemeral drainage meets the definition of a historic water of the
United States that no longer falls under federal jurisdiction but still falls under the jurisdiction of the State
Water Resource Control Board (SWRCB) and the Reginal Water Quality Control Board (RWQCB).
Impacts to the onsite ephemeral drainage will require the project proponent to obtain a Waste Discharge
Requirement (WDR) pursuant to the Porter-Cologne Water Quality Control Act.
8.0 CONCLUSIONS AND RECOMMENDATIONS
A project is normally considered to have a significant impact on wildlife if it will interfere substantially
with the movement of any resident or migratory fish or wildlife species; or substantially diminishes
habitat quantity or quality for dependent wildlife and plant species. Impacts to special status species and
their associated habitats are also considered significant if the impact would reduce or adversely modify a
habitat of recognized value to a sensitive wildlife species or to an individual of such species. This
guideline applies even to those species not formally listed as threatened, rare or endangered by the United
States Fish and Wildlife Service. Due to the past disturbances associated with rice farming within the
entire Study Area, project implementation should result in NO EFFECT to resident or migratory avian
species, special status plants, or protected wildlife species. The following recommendations are offered:
Adherence to an appropriate set-back from the ephemeral drainage and Highway 99 roadside
ditch will be required to minimize impacts to these features. If direct impacts are required,
further delineations and a Waste Discharge Permit will be required from the Regional Water
Quality Control Board.
To avoid potential impacts to (nesting) avian species, spring 2025 nesting season surveys will be
conducted. Survey results will be presented in an addendum to this Biological Resources
Assessment. Additionally, preconstruction nesting bird surveys will be required if impacts are
anticipated during the normal nesting season (February 1 – August 31).
Plant surveys were conducted outside the normal blooming cycle for all plants of concern. Spring
2025 blooming cycle plant surveys will be conducted. Survey results will be presented in an

Project Code: 2025-0047196
Project Name: TEN TURRI SOLAR FARM
Subject:List of threatened and endangered species that may occur in your proposed project
location or may be affected by your proposed project
To Whom It May Concern:
The enclosed species list identifies threatened, endangered, proposed and candidate species, as
well as proposed and final designated critical habitat, that may occur within the boundary of your
proposed project and/or may be affected by your proposed project. The species list fulfills the
requirements of the U.S. Fish and Wildlife Service (Service) under section 7(c) of the
Endangered Species Act (Act) of 1973, as amended (16 U.S.C. 1531 et seq.).
New information based on updated surveys, changes in the abundance and distribution of
species, changed habitat conditions, or other factors could change this list. Please feel free to
contact us if you need more current information or assistance regarding the potential impacts to
federally proposed, listed, and candidate species and federally designated and proposed critical
habitat. Please note that under 50 CFR 402.12(e) of the regulations implementing section 7 of the
Act, the accuracy of this species list should be verified after 90 days. This verification can be
completed formally or informally as desired. The Service recommends that verification be
completed by visiting the IPaC website at regular intervals during project planning and
implementation for updates to species lists and information. An updated list may be requested
through the IPaC system by completing the same process used to receive the enclosed list.
The purpose of the Act is to provide a means whereby threatened and endangered species and the
ecosystems upon which they depend may be conserved. Under sections 7(a)(1) and 7(a)(2) of the
Act and its implementing regulations (50 CFR 402 et seq.), Federal agencies are required to
utilize their authorities to carry out programs for the conservation of threatened and endangered
species and to determine whether projects may affect threatened and endangered species and/or
designated critical habitat.
A Biological Assessment is required for construction projects (or other undertakings having
similar physical impacts) that are major Federal actions significantly affecting the quality of the
human environment as defined in the National Environmental Policy Act (42 U.S.C. 4332(2)
Project code: 2025-0047196 01/25/2025 00:50:31 UTC
2 of 8
(c)). For projects other than major construction activities, the Service suggests that a biological
evaluation similar to a Biological Assessment be prepared to determine whether the project may
affect listed or proposed species and/or designated or proposed critical habitat. Recommended
contents of a Biological Assessment are described at 50 CFR 402.12.
If a Federal agency determines, based on the Biological Assessment or biological evaluation, that
listed species and/or designated critical habitat may be affected by the proposed project, the
agency is required to consult with the Service pursuant to 50 CFR 402. In addition, the Service
recommends that candidate species, proposed species and proposed critical habitat be addressed
within the consultation. More information on the regulations and procedures for section 7
consultation, including the role of permit or license applicants, can be found in the "Endangered
Species Consultation Handbook" at:
https://www.fws.gov/sites/default/files/documents/endangered-species-consultation-
handbook.pdf
Migratory Birds: In addition to responsibilities to protect threatened and endangered species
under the Endangered Species Act (ESA), there are additional responsibilities under the
Migratory Bird Treaty Act (MBTA) and the Bald and Golden Eagle Protection Act (BGEPA) to
protect native birds from project-related impacts. Any activity, intentional or unintentional,
resulting in take of migratory birds, including eagles, is prohibited unless otherwise permitted by
the U.S. Fish and Wildlife Service (50 C.F.R. Sec. 10.12 and 16 U.S.C. Sec. 668(a)). For more
information regarding these Acts, see https://www.fws.gov/program/migratory-bird-permit/what-
we-do.
The MBTA has no provision for allowing take of migratory birds that may be unintentionally
killed or injured by otherwise lawful activities. It is the responsibility of the project proponent to
comply with these Acts by identifying potential impacts to migratory birds and eagles within
applicable NEPA documents (when there is a federal nexus) or a Bird/Eagle Conservation Plan
(when there is no federal nexus). Proponents should implement conservation measures to avoid
or minimize the production of project-related stressors or minimize the exposure of birds and
their resources to the project-related stressors. For more information on avian stressors and
recommended conservation measures, see https://www.fws.gov/library/collections/threats-birds.
In addition to MBTA and BGEPA, Executive Order 13186: Responsibilities of Federal Agencies
to Protect Migratory Birds, obligates all Federal agencies that engage in or authorize activities
that might affect migratory birds, to minimize those effects and encourage conservation measures
that will improve bird populations. Executive Order 13186 provides for the protection of both
migratory birds and migratory bird habitat. For information regarding the implementation of
Executive Order 13186, please visit https://www.fws.gov/partner/council-conservation-
migratory-birds.
We appreciate your concern for threatened and endangered species. The Service encourages
Federal agencies to include conservation of threatened and endangered species into their project
planning to further the purposes of the Act. Please include the Consultation Code in the header of
this letter with any request for consultation or correspondence about your project that you submit
to our office.

ENDANGERED SPECIES ACT SPECIES
There is a total of 12 threatened, endangered, or candidate species on this species list.
Species on this list should be considered in an effects analysis for your project and could include
species that exist in another geographic area. For example, certain fish may appear on the species
list because a project could affect downstream species.
IPaC does not display listed species or critical habitats under the sole jurisdiction of NOAA
Fisheries , as USFWS does not have the authority to speak on behalf of NOAA and the
Department of Commerce.
See the "Critical habitats" section below for those critical habitats that lie wholly or partially
within your project area under this office's jurisdiction. Please contact the designated FWS office
if you have questions.

The soil surveys that comprise your AOI were mapped at
1:24,000.
Warning: Soil Map may not be valid at this scale.
Enlargement of maps beyond the scale of mapping can cause
misunderstanding of the detail of mapping and accuracy of soil
line placement. The maps do not show the small areas of
contrasting soils that could have been shown at a more detailed
scale.
Please rely on the bar scale on each map sheet for map
measurements.

Web Soil Survey URL:
Coordinate System: Web Mercator (EPSG:3857)
Maps from the Web Soil Survey are based on the Web Mercator
projection, which preserves direction and shape but distorts
distance and area. A projection that preserves area, such as the
Albers equal-area conic projection, should be used if more
accurate calculations of distance or area are required.
This product is generated from the USDA-NRCS certified data as
of the version date(s) listed below.
Soil Survey Area: Butte Area, California, Parts of Butte and
Plumas Counties
Survey Area Data: Version 22, Sep 4, 2024
Soil map units are labeled (as space allows) for map scales
1:50,000 or larger.
Date(s) aerial images were photographed: Jun 3, 2023—Sep 8,
2023
The orthophoto or other base map on which the soil lines were
compiled and digitized probably differs from the background
imagery displayed on these maps. As a result, some minor
shifting of map unit boundaries may be evident.
