RE: Grading Permit Request — Main Elk Creek Ranch (MECR) — Stream Restoration & Stabilization
Project.
Dear Mr. Schwaller:
Colorado River Engineering is providing this letter to supplement a Garfield County grading permit
application for a planned stream restoration and aquatic habitat improvement project located on
Main Elk Creek within the boundaries of Main Elk Creek Ranch (PIN: 212502100188, 212502400002,
and 212501200100). The work being completed in the channel is covered under a U.S. Army Corps
of Engineers General Permit 12 (SPK -2017-00295) and a Garfield County floodplain development
permit (FDPA-09-17-8575), both of which are attached. While these permits were issued last year,
the work had been delayed; however, work will be completed this summer. A requirement of the
FDPA was that a grading permit be obtained in order to bond the revegetation/weed control portion
of the stream restoration work. The vast majority of work being proposed is below the ordinary high
water line of Main Elk Creek with the exception of a few spots where eroded banks need to be sloped
back; therefore the main purpose of this permit is to secure the revegetation of all disturbed areas
above the high water line in the channel of Main Elk Creek. A vicinity map is attached as Figure 1.
Although this works falls into the category of "minor grading permit" based on the amount of
grading, we are providing the revegetation and reclamation plan as requested in the FDPA. Total area
to be revegetated for coir banks, cobble toe placement, riparian banks totals 0.14 acres.
Site Plan
Many of the requirements of the site plan are not applicable to this project. All of the work is being
done within the property boundaries of the applicant. Design sheets and typical cross sections of
work to be performed from Five Rivers, Inc are attached to this document. The design sheets being
provided illustrate the extent of the work to be performed in the channel. This area has not mapped
by FEMA; therefore, no floodplain maps are available. A General Site Plan is attached as Figure 2
showing the existing contours (topographic map), restoration extent, existing roads, property
boundaries, and streams. In addition to this general map, areas of restoration are further detailed in
the attached design sheets from Five Rivers, Inc.
Erosion Control Plan
In the channel, the main goal of this restoration work is to repair and control erosion that has already
taken place due to overgrazing and flooding events. Once restoration has taken place, small cobble
coffer dams can be placed upstream of areas where major excavation work is underway to deflect

flows away from the bank. These dams can then be moved downstream where needed and
incorporated into the next feature after bank restoration work is completed.
Soils Report
A soils report is attached.
Vegetation and Reclamation Plan
Soil and Material Handling
The majority of material that will be handled during this restoration work is river cobble and gravel,
very little soil will actually be worked. Soil removed on-site will be used immediately in the stream
restoration work and will not be stored for more than a few minutes. No long-term soil stockpiles
requiring cover are needed as soil will be used immediately.
Weed Management Plan
A noxious weed inventory and management plan will be completed by per Exhibit A of the Floodplain
Development Permit.
Site Revegetation and Restoration
The seed mixes used will vary by location of disturbance and are listed below:
General Streambank and Riparian Seed Mix
Western wheatgrass (Pascopyrum smithii) Arriba 25%
Streambank wheatgrass (Elymus lanceolatus) SODAR 40%
Slender wheatgrass (Elymus trachycaulus) SAN LUIS 15%
Mountain Brome (Bromus marginatus) Garnet 20%
Rate — 25-30 lbs per acre —seed raked into soil, and lightly tracked packed with equipment and placed
in upper coir lifts)

Rate 25 pounds per acre placed in lower coir lifts, seeded on lateral bar edges
General Mix
A Western Native Seed Montane Erosion Control Mix (approximately 50 pounds) will be used for
upland disturbance areas and includes the following species:
Mt Brome (Bromus marginatus) 45%
Slender Wheatgrass (Elymus trachycaulus) 45%
Western Wheatgras (Pascopyrum smithii) 10%
Planting Schedule
Planting of the disturbed areas will take place after the restoration work has completed. The seed
application rate is provided above under the different areas that will be reseeded. Seeds will be
irrigated if necessary, until established.
Cost Estimate
The estimate for the vegetation and reclamation plan is based on a cost of $2,500/acre (per
conversations with Steve Anthony). A fill volume/area table is attached for the restoration work. The
revegetation area estimate includes: coir fabric fill, riparian bank construction and cobble toe
placement. Revegetation work totals 0.14 acres for a total cost estimate of $350.

Engineering Properties
This table gives the engineering classifications and the range of engineering
properties for the layers of each soil in the survey area.
Hydrologic soil group is a group of soils having similar runoff potential under
similar storm and cover conditions. The criteria for determining Hydrologic soil
group is found in the National Engineering Handbook, Chapter 7 issued May
2007(http://directives.sc.egov.usda.gov/OpenNonWebContent.aspx?
content=17757.wba). Listing HSGs by soil map unit component and not by soil
series is a new concept for the engineers. Past engineering references contained
lists of HSGs by soil series. Soil series are continually being defined and
redefined, and the list of soil series names changes so frequently as to make the
task of maintaining a single national list virtually impossible. Therefore, the
criteria is now used to calculate the HSG using the component soil properties
and no such national series lists will be maintained. All such references are
obsolete and their use should be discontinued. Soil properties that influence
runoff potential are those that influence the minimum rate of infiltration for a bare
soil after prolonged wetting and when not frozen. These properties are depth to a
seasonal high water table, saturated hydraulic conductivity after prolonged
wetting, and depth to a layer with a very slow water transmission rate. Changes
in soil properties caused by land management or climate changes also cause the
hydrologic soil group to change. The influence of ground cover is treated
independently. There are four hydrologic soil groups, A, B, C, and D, and three
dual groups, A/D, B/D, and C/D. In the dual groups, the first letter is for drained
areas and the second letter is for undrained areas.
The four hydrologic soil groups are described in the following paragraphs:
Group A. Soils having a high infiltration rate (low runoff potential) when
thoroughly wet. These consist mainly of deep, well drained to excessively
drained sands or gravelly sands. These soils have a high rate of water
transmission.
Group B. Soils having a moderate infiltration rate when thoroughly wet. These
consist chiefly of moderately deep or deep, moderately well drained or well
drained soils that have moderately fine texture to moderately coarse texture.
These soils have a moderate rate of water transmission.
Group C. Soils having a slow infiltration rate when thoroughly wet. These consist
chiefly of soils having a layer that impedes the downward movement of water or
soils of moderately fine texture or fine texture. These soils have a slow rate of
water transmission.
Group D. Soils having a very slow infiltration rate (high runoff potential) when
thoroughly wet. These consist chiefly of clays that have a high shrink -swell
potential, soils that have a high water table, soils that have a claypan or clay
layer at or near the surface, and soils that are shallow over nearly impervious
material. These soils have a very slow rate of water transmission.
Depth to the upper and lower boundaries of each layer is indicated.

Texture is given in the standard terms used by the U.S. Department of
Agriculture. These terms are defined according to percentages of sand, silt, and
clay in the fraction of the soil that is less than 2 millimeters in diameter. "Loam,"
for example, is soil that is 7 to 27 percent clay, 28 to 50 percent silt, and less than
52 percent sand. If the content of particles coarser than sand is 15 percent or
more, an appropriate modifier is added, for example, "gravelly."
Classification of the soils is determined according to the Unified soil classification
system (ASTM, 2005) and the system adopted by the American Association of
State Highway and Transportation Officials (AASHTO, 2004).
The Unified system classifies soils according to properties that affect their use as
construction material. Soils are classified according to particle -size distribution of
the fraction less than 3 inches in diameter and according to plasticity index, liquid
limit, and organic matter content. Sandy and gravelly soils are identified as GW,
GP, GM, GC, SW, SP, SM, and SC; silty and clayey soils as ML, CL, OL, MH,
CH, and OH; and highly organic soils as PT. Soils exhibiting engineering
properties of two groups can have a dual classification, for example, CL -ML.
The AASHTO system classifies soils according to those properties that affect
roadway construction and maintenance. In this system, the fraction of a mineral
soil that is less than 3 inches in diameter is classified in one of seven groups
from A-1 through A-7 on the basis of particle -size distribution, liquid limit, and
plasticity index. Soils in group A-1 are coarse grained and low in content of fines
(silt and clay). At the other extreme, soils in group A-7 are fine grained. Highly
organic soils are classified in group A-8 on the basis of visual inspection.
If laboratory data are available, the A-1, A-2, and A-7 groups are further
classified as A -1-a, A -1-b, A-2-4, A-2-5, A-2-6, A-2-7, A-7-5, or A-7-6. As an
additional refinement, the suitability of a soil as subgrade material can be
indicated by a group index number. Group index numbers range from 0 for the
best subgrade material to 20 or higher for the poorest.
Percentage of rock fragments larger than 10 inches in diameter and 3 to 10
inches in diameter are indicated as a percentage of the total soil on a dry -weight
basis. The percentages are estimates determined mainly by converting volume
percentage in the field to weight percentage. Three values are provided to
identify the expected Low (L), Representative Value (R), and High (H).
Percentage (of soil particles) passing designated sieves is the percentage of the
soil fraction less than 3 inches in diameter based on an ovendry weight. The
sieves, numbers 4, 10, 40, and 200 (USA Standard Series), have openings of
4.76, 2.00, 0.420, and 0.074 millimeters, respectively. Estimates are based on
laboratory tests of soils sampled in the survey area and in nearby areas and on
estimates made in the field. Three values are provided to identify the expected
Low (L), Representative Value (R), and High (H).
Liquid limit and plasticity index (Atterberg limits) indicate the plasticity
characteristics of a soil. The estimates are based on test data from the survey
area or from nearby areas and on field examination. Three values are provided to
identify the expected Low (L), Representative Value (R), and High (H).

Physical Soil Properties
This table shows estimates of some physical characteristics and features that
affect soil behavior. These estimates are given for the layers of each soil in the
survey area. The estimates are based on field observations and on test data for
these and similar soils.
Depth to the upper and lower boundaries of each layer is indicated.
Particle size is the effective diameter of a soil particle as measured by
sedimentation, sieving, or micrometric methods. Particle sizes are expressed as
classes with specific effective diameter class limits. The broad classes are sand,
silt, and clay, ranging from the larger to the smaller.
Sand as a soil separate consists of mineral soil particles that are 0.05 millimeter
to 2 millimeters in diameter. In this table, the estimated sand content of each soil
layer is given as a percentage, by weight, of the soil material that is less than 2
millimeters in diameter.
Silt as a soil separate consists of mineral soil particles that are 0.002 to 0.05
millimeter in diameter. In this table, the estimated silt content of each soil layer is
given as a percentage, by weight, of the soil material that is less than 2
millimeters in diameter.
Clay as a soil separate consists of mineral soil particles that are less than 0.002
millimeter in diameter. In this table, the estimated clay content of each soil layer
is given as a percentage, by weight, of the soil material that is less than 2
millimeters in diameter.
The content of sand, silt, and clay affects the physical behavior of a soil. Particle
size is important for engineering and agronomic interpretations, for determination
of soil hydrologic qualities, and for soil classification.
The amount and kind of clay affect the fertility and physical condition of the soil
and the ability of the soil to adsorb cations and to retain moisture. They influence
shrink -swell potential, saturated hydraulic conductivity (Ksat), plasticity, the ease
of soil dispersion, and other soil properties. The amount and kind of clay in a soil
also affect tillage and earthmoving operations.
Moist bulk density is the weight of soil (ovendry) per unit volume. Volume is
measured when the soil is at field moisture capacity, that is, the moisture content
at 1/3- or 1/10 -bar (33kPa or 10kPa) moisture tension. Weight is determined after
the soil is dried at 105 degrees C. In the table, the estimated moist bulk density
of each soil horizon is expressed in grams per cubic centimeter of soil material
that is less than 2 millimeters in diameter. Bulk density data are used to compute
linear extensibility, shrink -swell potential, available water capacity, total pore
space, and other soil properties. The moist bulk density of a soil indicates the
pore space available for water and roots. Depending on soil texture, a bulk
density of more than 1.4 can restrict water storage and root penetration. Moist
bulk density is influenced by texture, kind of clay, content of organic matter, and
soil structure.

Saturated hydraulic conductivity (Ksat) refers to the ease with which pores in a
saturated soil transmit water. The estimates in the table are expressed in terms
of micrometers per second. They are based on soil characteristics observed in
the field, particularly structure, porosity, and texture. Saturated hydraulic
conductivity (Ksat) is considered in the design of soil drainage systems and
septic tank absorption fields.
Available water capacity refers to the quantity of water that the soil is capable of
storing for use by plants. The capacity for water storage is given in inches of
water per inch of soil for each soil layer. The capacity varies, depending on soil
properties that affect retention of water. The most important properties are the
content of organic matter, soil texture, bulk density, and soil structure. Available
water capacity is an important factor in the choice of plants or crops to be grown
and in the design and management of irrigation systems. Available water
capacity is not an estimate of the quantity of water actually available to plants at
any given time.
Linear extensibility refers to the change in length of an unconfined clod as
moisture content is decreased from a moist to a dry state. It is an expression of
the volume change between the water content of the clod at 1/3- or 1/10 -bar
tension (33kPa or 10kPa tension) and oven dryness. The volume change is
reported in the table as percent change for the whole soil. The amount and type
of clay minerals in the soil influence volume change.
Linear extensibility is used to determine the shrink -swell potential of soils. The
shrink -swell potential is low if the soil has a linear extensibility of less than 3
percent; moderate if 3 to 6 percent; high if 6 to 9 percent; and very high if more
than 9 percent. If the linear extensibility is more than 3, shrinking and swelling
can cause damage to buildings, roads, and other structures and to plant roots.
Special design commonly is needed.
Organic matter is the plant and animal residue in the soil at various stages of
decomposition. In this table, the estimated content of organic matter is expressed
as a percentage, by weight, of the soil material that is less than 2 millimeters in
diameter. The content of organic matter in a soil can be maintained by returning
crop residue to the soil.
Organic matter has a positive effect on available water capacity, water infiltration,
soil organism activity, and tilth. It is a source of nitrogen and other nutrients for
crops and soil organisms.
Erosion factors are shown in the table as the K factor (Kw and Kf) and the T
factor. Erosion factor K indicates the susceptibility of a soil to sheet and rill
erosion by water. Factor K is one of six factors used in the Universal Soil Loss
Equation (USLE) and the Revised Universal Soil Loss Equation (RUSLE) to
predict the average annual rate of soil loss by sheet and rill erosion in tons per
acre per year. The estimates are based primarily on percentage of silt, sand, and
organic matter and on soil structure and Ksat. Values of K range from 0.02 to
0.69. Other factors being equal, the higher the value, the more susceptible the
soil is to sheet and rill erosion by water.
Erosion factor Kw indicates the erodibility of the whole soil. The estimates are
modified by the presence of rock fragments.
Erosion factor Kf indicates the erodibility of the fine -earth fraction, or the material
less than 2 millimeters in size.
USDA Natural Resources Web Soil Survey 6/5/2019
Conservation Service National Cooperative Soil Survey Page 2 of 7
Physical Soil Properties ---Rifle Area, Colorado, Parts of Garfield and Mesa Counties Main Elk Ranch -phys
Erosion factor T is an estimate of the maximum average annual rate of soil
erosion by wind and/or water that can occur without affecting crop productivity
over a sustained period. The rate is in tons per acre per year.
Wind erodibility groups are made up of soils that have similar properties affecting
their susceptibility to wind erosion in cultivated areas. The soils assigned to
group 1 are the most susceptible to wind erosion, and those assigned to group 8
are the least susceptible. The groups are described in the "National Soil Survey
Handbook."
Wind erodibility index is a numerical value indicating the susceptibility of soil to
wind erosion, or the tons per acre per year that can be expected to be lost to
wind erosion. There is a close correlation between wind erosion and the texture
of the surface layer, the size and durability of surface clods, rock fragments,
organic matter, and a calcareous reaction. Soil moisture and frozen soil layers
also influence wind erosion.

In accordance with Section 404 of the Clean Water Act (33 U.S.C. 1344) and Section 10 of the Rivers
and Harbors Act of 1899 (33 U.S.C. 403), the District Engineer, U.S. Army, Corps of Engineers,
Albuquerque, Omaha, and Sacramento Districts, hereby re -issue Regional General Permit (RGP) 12 for
certain limited discharges of dredged and fill material within waters of the U.S. associated with aquatic
habitat improvement for stream channel activities in Colorado.
LOCATION: This RGP 12 is applicable to all waters of the United States within the State of Colorado.
SCOPE OF WORK: This RGP authorizes certain discharges of dredged and fill material for stream
habitat improvement associated with the creation or enhancement of fish habitat components, provided
those activities result in net increases in aquatic resource functions and services. This permit does not
authorize the loss of greater than 0.5 acre of wetland.
These activities involve placement of materials such as large woody debris, boulders, and other
materials into the active stream channel or actual manipulation of the active channel itself in an effort to
improve fish habitat (e.g., create pools, trap gravel) and can include such structures as boulder or log
weirs, jetties and deflectors, rootwads, and placement of spawning gravel. Examples of typical in -
stream structures can be found online at: http://www.spa.usace.army.mil/Missions/Regulatory-Program-and-
Permits/Stream-Management/. Other structures not specifically listed may be authorized by this permit on
a case-by-case basis. Project goals and standards must be achieved within a reasonable time frame to
benefit the environment. Mitigation and monitoring may be required based on the nature, extent, and
duration of the impact and/or risk of the project plan not achieving performance standards.
NOTIFICATION AND APPROVAL PROCEDURES: Written notification requesting verification
and concurrence with the requirements of the RGP must be sent to the Corps of Engineers (Corps)
office that services the area of the project location. To determine the appropriate regulatory office and

Regional General Permit 12 Aquatic Habitat Improvement for Stream Channels
GENERAL CONDITIONS: To qualify for this RGP authorization, the prospective permittee must
comply with the following general conditions (GC), in addition to any regional or case specific conditions
imposed by the division engineer or District Engineer:
1. Upon receiving approval to perform work under this RGP, the permittee will have two years to
complete the work or until the permit expires or is revoked, unless specified otherwise in a
Corps verification letter. If the permittee commenced work on the authorized activity or is under
contract to commence work when the permit expires or is revoked, the permittee will have one
more year or until the original expiration, whichever is less, to complete the construction. Upon
completion of the work, the permittee shall submit a signed Certification of Compliance form to
the Corps. The certification shall include:
a. A statement that the work was done in accordance with the Corps authorization,
including any special conditions;
b. A statement that the required compensatory mitigation, if applicable, was done in
accordance with the permit conditions; and
c. The signature of the permittee certifying the completion of the work and mitigation.
2. For all projects that include a design -build component, the permittee shall submit a complete set
of as -built drawings to the Corps within 90 days following the completion of work.
3. Structures or fill authorized by this permit shall not impede waterborne navigation, including
rafting and canoeing, or create a hazard to navigation in waterways. Any interference with
navigation may require removal or modification of the structure at the permittee's expense.
4. Activities authorized by this permit shall be designed to withstand expected high flows and
maintain preconstruction surface flow rates from the site to the maximum extent practicable.
5. The construction of recreational features (e.g., water parks, kayak courses) and flood control
projects are not authorized by this permit.
6. Material may not be placed in any location or manner that will impair surface water flows into or
out of any special aquatic sites. The permittee must take precautions to avoid and minimize
temporary impacts and protect wetlands and riffle -pool complexes from damage during access
and construction. Temporary fills must be removed in their entirety and the affected areas
returned to pre -construction conditions, including the revegetation of affected areas, as
appropriate. This permit does not authorize the loss of greater than 0.5 acre of wetland.
7. The activity must comply with applicable FEMA -approved state or local floodplain management
requirements.
8. Heavy equipment working in wetlands or mudflats must be placed on mats, or other measures
must be taken to minimize soil disturbance.
9. The District Engineer may designate, after notice and opportunity for public comment, additional
waters officially designated by the State of Colorado as having particular environmental or
ecological significance, such as outstanding national resource waters or state natural heritage
sites. The District Engineer may also designate additional critical resource waters after notice
and opportunity for public comment.
Page 5 of 14
Regional General Permit 12 Aquatic Habitat Improvement for Stream Channels
10. The District Engineer may determine on a case-by-case basis that compensatory mitigation is
required to ensure that the activity results in no more than minimal adverse environmental
effects. The District Engineer will consider the following factors when determining appropriate
and practicable mitigation necessary to ensure that the individual and cumulative adverse
environmental effects are no more than minimal:
(a) The activity must be designed and constructed 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 (i.e., on site).
(b) Mitigation in all its forms (avoiding, minimizing, rectifying, reducing, or compensating for
resource losses) will be required to the extent necessary to ensure that the individual and
cumulative adverse environmental effects are no more than minimal.
(c) Compensatory mitigation plans for RGP activities in or near streams or other open waters
will normally include a requirement for the restoration or enhancement, maintenance, and
legal protection (e.g., conservation easements) of riparian areas next to open waters. In
some cases, the restoration of riparian areas may be the only compensatory mitigation
required. Restored riparian areas should consist of native species. The width of the required
riparian area will address documented water quality or aquatic habitat loss concerns.
Normally, the riparian area will be 25 to 50 feet wide on each side of the stream, but the
District Engineer may require slightly wider riparian areas to address documented water
quality or habitat loss concerns. Where both wetlands and open waters exist on the project
site, the District Engineer will determine the appropriate compensatory mitigation (e.g.,
riparian areas and/or wetlands compensation) based on what is best for the aquatic
environment on a watershed basis. In cases where riparian areas are determined to be the
most appropriate form of compensatory mitigation, the District Engineer may waive or
reduce any requirement to provide wetland compensatory mitigation for wetland losses.
(d) Compensatory mitigation projects provided to offset losses of aquatic resources must
comply with the applicable provisions of 33 CFR part 332.
(1) The prospective permittee is responsible for proposing an appropriate compensatory
mitigation option if compensatory mitigation is necessary to ensure that the activity
results in no more than minimal adverse environmental effects.
(2) If permittee -responsible mitigation is the proposed option, the prospective permittee
is responsible for submitting a mitigation plan. A conceptual or detailed mitigation plan
may be used by the District Engineer to make the decision on the RGP verification
request, but a final mitigation plan that addresses the applicable requirements of 33 CFR
parts 332.4(c)(2) — (14) must be approved by the District Engineer before the permittee
begins work in waters of the United States, unless the District Engineer determines that
prior approval of the final mitigation plan is not practicable or not necessary to ensure
timely completion of the required compensatory mitigation (see 33 CFR part
332.3(k)(3)).
(3) If mitigation bank or in -lieu fee program credits are the proposed option, the
mitigation plan only needs to address the baseline conditions at the impact site and the
number of credits to be provided.
Page 6 of 14
Regional General Permit 12 Aquatic Habitat Improvement for Stream Channels
(4) Compensatory mitigation requirements (e.g., resource type and amount to be
provided as compensatory mitigation, site protection, ecological performance standards,
monitoring requirements) may be added through special conditions added to the RGP
authorization.
(e) Compensatory mitigation will not be used to increase the acreage losses allowed by the
acreage limits of this RGP. For example, RGP 12 cannot be used to authorize any activity
resulting in the loss of greater than 0.5 acre of waters of the United States, even if
compensatory mitigation is provided that replaces or restores some of the lost waters.
However, compensatory mitigation can and should be used, as necessary, to ensure that an
activity already meeting the established acreage limits also satisfies the no more than
minimal impact requirement for this RGP.
(f) Permittees may propose the use of mitigation banks, in -lieu fee programs, or permittee -
responsible mitigation. For permittee -responsible mitigation, the special conditions of the
RGP verification must clearly indicate the party or parties responsible for the implementation
and performance of the compensatory mitigation project, and, if required, its long-term
management.
When mitigation is required, no work in waters of the United States may occur until the District
Engineer has approved a specific mitigation plan or has determined that prior approval of a final
mitigation plan is not practicable or not necessary to ensure timely completion of the required
compensatory mitigation. For projects requiring compensatory mitigation, please refer to the
Mitigation and Monitoring Guidelines located at:
http://www.spd.usace.army.mil/Portals/13/docs/regulatory/mitigation/MitMon.pdf
11. No activity may substantially disrupt the necessary life cycle movements of those species of
aquatic life indigenous to the waterbody, including those species that normally migrate through
the area.
12. Destruction of riparian or riverine vegetation, especially mature cottonwoods, shall be avoided to
the maximum extent practicable. The permittee is cautioned that cottonwoods may be locally
very important for several protected species, including the yellow -billed cuckoo, and bald
eagles, which are protected under the Bald and Golden Eagle Act. If the authorized work
causes damage to riparian vegetation that is not directly covered by a permanent feature, these
scarred areas shall be replanted with a mixture of native trees, shrubs, forbs and grasses.
Seeding, sprigging, or other means of planting native woody and herbaceous plants is highly
recommended and advantageous to further stabilize stream banks. For further information on
planting, please contact the local Natural Resources Conservation Service or Corps office.
13. Appropriate soil erosion and sediment controls must be used and maintained in effective
operating condition during construction, and all exposed soil and other fills, as well as any work
below the ordinary high water mark, must be permanently stabilized at the earliest practicable
date. Erosion control fabrics/blankets may be required on a case-by-case basis. All disturbed
areas, including the riparian and upland buffer zones, shall be revegetated with native species
to prevent erosion. These areas shall be monitored and maintained to ensure vegetative
success.
Page 7 of 14
Regional General Permit 12 Aquatic Habitat Improvement for Stream Channels
14. Activities in breeding areas for migratory waterfowl must be avoided to the maximum extent
practicable. On a case-by-case basis, the Corps may restrict the timing of construction in order
to avoid and minimize impacts to migratory waterfowl during the breeding season.
15. (a) No activity is authorized under this RGP which is likely to directly or indirectly jeopardize the
continued existence of a threatened or endangered species or a species proposed for such
designation, as identified under the Federal Endangered Species Act (ESA), or which will
directly or indirectly destroy or adversely modify the critical habitat of such species. No activity is
authorized under this RGP which "may affect" a listed species or critical habitat, unless Section
7 consultation addressing the effects of the proposed activity has been completed. Direct effects
are the immediate effects on listed species and critical habitat caused by the RGP activity.
Indirect effects are those effects on listed species and critical habitat that are caused by the
RGP activity and are later in time, but still are reasonably certain to occur.
(b) Section 7 consultation may be necessary for the activity and the respective lead federal
agency would be responsible for fulfilling its obligation under Section 7 of the ESA. Federal
agencies should follow their own procedures for complying with the requirements of the ESA. If
pre -construction notification is required for the proposed activity, Federal permittees must
provide the District Engineer with the appropriate documentation to demonstrate compliance
with those requirements. The District Engineer will verify that the appropriate documentation has
been submitted.
(c) Non -Federal permittees must submit notification to the District Engineer if any listed species
or designated critical habitat might be affected or is in the vicinity of the activity, or if the activity
is located in designated critical habitat, and shall not begin work on the activity until notified by
the District Engineer that the requirements of the ESA have been satisfied and that the activity
is authorized. For activities that might affect Federally -listed endangered or threatened species
or designated critical habitat, the pre -construction notification must include the name(s) of the
endangered or threatened species that might be affected by the proposed activity or that utilize
the designated critical habitat that might be affected by the proposed work.
The District Engineer will determine whether the proposed activity "may affect" or will have "no
effect" to listed species and designated critical habitat and will notify the non -Federal applicant
of the Corps' determination within 45 days of receipt of a complete notification package. If the
non -Federal applicant has not heard back from the Corps within 45 days, the applicant must still
wait for notification from the Corps.
(d) As a result of formal or informal consultation with the U.S. Fish and Wildlife Service
(USFWS), the District Engineer may add species-specific permit conditions to this RGP.
(e) Authorization of an activity by a RGP does not authorize the "take" of a threatened or
endangered species as defined under the ESA. In the absence of separate authorization (e.g.,
an ESA Section 10 Permit, a Biological Opinion with "incidental take" provisions, etc.) from the
USFWS, the Endangered Species Act prohibits any person subject to the jurisdiction of the
United States to take a listed species, where "take" means to harass, harm, pursue, hunt, shoot,
wound, kill, trap, capture, or collect, or to attempt to engage in any such conduct. The word
"harm" in the definition of "take" means 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.
Page 8 of 14
Regional General Permit 12 Aquatic Habitat Improvement for Stream Channels
(f) Information on the location of threatened and endangered species and their critical habitat
can be obtained directly from the offices of the USFWS or their World Wide Web pages at
http://www.fws.gov/ or http://www.fws.gov/ipac.
16. The permittee is responsible for ensuring their action complies with the Migratory Bird Treaty
Act and the Bald and Golden Eagle Protection Act. The permittee is responsible for contacting
appropriate local office of the USFWS to determine applicable measures to reduce impacts to
migratory birds or eagles, including whether "incidental take" permits are necessary and
available under the Migratory Bird Treaty Act or Bald and Golden Eagle Protection Act for a
particular activity.
17. (a) In cases where the District Engineer determines that the activity may affect properties listed,
or eligible for listing, in the National Register of Historic Places, the activity is not authorized,
until the requirements of Section 106 of the National Historic Preservation Act (NHPA) have
been satisfied.
(b) Federal permittees should follow their own procedures for complying with the requirements
of Section 106 of the National Historic Preservation Act. Federal permittees must provide the
District Engineer with the appropriate documentation to demonstrate compliance with those
requirements. The District Engineer will verify that the appropriate documentation has been
submitted. If the appropriate documentation is not submitted, then additional consultation under
Section 106 may be necessary. The respective federal agency is responsible for fulfilling its
obligation to comply with Section 106.
(c) Non-federal permittees must identify in their notification which historic properties may be
affected by the proposed work or include a vicinity map indicating the location of the historic
properties or the potential for the presence of historic properties.
Assistance regarding information on the location of or potential for the presence of historic
resources can be sought from the State Historic Preservation Officer or Tribal Historic
Preservation Officer, as appropriate, and the National Register of Historic Places (see 33 CFR
part 330.4(g)). When reviewing notification packages, District Engineers will comply with the
current procedures for addressing the requirements of Section 106 of the National Historic
Preservation Act. The District Engineer shall make a reasonable and good faith effort to carry
out appropriate identification efforts, which may include background research, consultation, oral
history interviews, sample field investigation, and field survey. Based on the information
submitted and these efforts, the District Engineer shall determine whether the proposed activity
has the potential to cause an effect on the historic properties. Where the non -Federal applicant
has identified historic properties on which the activity may have the potential to cause effects
and so notified the Corps, the non -Federal applicant shall not begin the activity until notified by
the District Engineer either that the activity has no potential to cause effects or that consultation
under Section 106 of the NHPA has been completed.
(d) The District Engineer will notify the prospective permittee within 45 days of receipt of a
complete notification package whether NHPA Section 106 consultation is required. Section 106
consultation is not required when the Corps determines that the activity does not have the
potential to cause effects on historic properties (see 36 CFR part 800.3(a)). If NHPA Section
106 consultation is required and will occur, the District Engineer will notify the non -Federal
applicant that he or she cannot begin work until Section 106 consultation is completed. If the
Page 9 of 14
Regional General Permit 12 Aquatic Habitat Improvement for Stream Channels
non -Federal applicant has not heard back from the Corps within 45 days, the applicant must still
wait for notification from the Corps.
(e) Prospective permittees should be aware that Section 110k of the NHPA (16 U.S.C. 470h -
2(k)) prevents the Corps from granting a permit or other assistance to an applicant who, with
intent to avoid the requirements of Section 106 of the NHPA, has intentionally significantly
adversely affected a historic property to which the permit would relate, or having legal power to
prevent it, allowed such significant adverse effect to occur, unless the Corps, after consultation
with the Advisory Council on Historic Preservation (ACHP), determines that circumstances
justify granting such assistance despite the adverse effect created or permitted by the applicant.
If circumstances justify granting the assistance, the Corps is required to notify the ACHP and
provide documentation specifying the circumstances, the degree of damage to the integrity of
any views obtained from the applicant, SHPO/THPO, appropriate Indian tribes if the undertaking
occurs on or affects historic properties on tribal lands or affects properties of interest to those
tribes, and other parties known to have a legitimate interest in the impacts to the permitted
activity on historic properties.
If any previously unknown historic, cultural or archeological remains and artifacts are discovered
while accomplishing the activity authorized by this permit, the permittee must immediately notify
the District Engineer of what was found, and to the maximum extent practicable, avoid
construction activities that may affect the remains and artifacts until the required coordination
has been completed. The District Engineer will initiate the Federal, Tribal and state coordination
required to determine if the items or remains warrant a recovery effort or if the site is eligible for
listing in the National Register of Historic Places.
18. To ensure that all habitat improvement structures are safely designed, the District Engineer may
require non -Federal applicants to demonstrate that the structures have been designed by
qualified persons. The District Engineer may also require documentation that the design has
been independently reviewed by similarly qualified persons, and appropriate modifications made
to ensure safety.
19. If a conditioned water quality certification is issued for the project, (i.e., for projects located on
Southern Ute or Ute Mountain Ute Tribal Lands) the permittee must comply with the conditions
specified in the certification as special conditions to this permit. In Colorado, excluding Indian
lands, regional general permits are unconditionally certified by statute.
20. This permit does not authorize discharges of dredged or fill material associated with
channelization, ditching, mechanized land clearing, cutting off meanders, or blocking off
channels.
21. All construction debris (including excess dredged or fill materials, wood, cleared vegetation,
concrete, and all other materials not specifically authorized by the permit) shall be disposed of in
an upland area in such a manner that it cannot enter a waterway or wetland.
22. Dredged or fill material shall not consist of unsuitable material (e.g., trash, debris, waste metal
products, asphalt, car bodies, tires, etc.) and must be free from toxic pollutants in toxic amounts
(see Section 307 of the Clean Water Act).
Page 10 of 14
Regional General Permit 12 Aquatic Habitat Improvement for Stream Channels
23. The use of grout is not allowed by this permit unless, after a case-by-case review, the Corps
makes a written determination that the use of grout would not cause more than minor impacts to
the aquatic resource.
24. Discharges into fish spawning areas during spawning seasons are not authorized by this permit
unless the CPW provides recommendation to the Corps that the applicant's discharge will not
have adverse impacts. In every case, care must be taken so that work does not adversely
impact natural recruitment of fisheries. Additionally, special conditions may be required for
projects that would impact aquatic species of tribal or state concern. Activities that result in the
physical destruction (e.g., through excavation, fill, or downstream smothering by substantial
turbidity) of an important spawning area are not authorized by this RGP.
25. Discharges of dredged or fill material shall not occur in the proximity of a water supply intake,
shall not limit the ability of any existing diversion structure to appropriate water, shall not impair
the ability to deliver vested water rights, and shall not adversely impact a stream gauging
station.
26. Activities shall not impair reserved tribal rights including, but not limited to, reserved water rights
and treaty fishing and hunting rights.
27. (a) No activity may occur in a component of the National Wild and Scenic River System, or in a
river officially designated by Congress as a "study river" for possible inclusion in the system
while the river is in an official study status, unless the appropriate Federal agency with direct
management responsibility for such river, has determined in writing that the proposed activity
will not adversely affect the Wild and Scenic River designation or study status.
(b) If a proposed RGP activity will occur in a component of the National Wild and Scenic River
System, or in a river officially designated by Congress as a "study river" for possible inclusion in
the system while the river is in an official study status, the District Engineer will coordinate with
the Federal agency with direct management responsibility for that river. The permittee shall not
begin the RGP activity until notified by the District Engineer that the Federal agency with direct
management responsibility for that river has determined in writing that the proposed RGP
activity will not adversely affect the Wild and Scenic River designation or study status.
(c) Information on Wild and Scenic Rivers may be obtained from the appropriate Federal land
management agency responsible for the designated Wild and Scenic River or study river (e.g.,
National Park Service, U.S. Forest Service, Bureau of Land Management, U.S. Fish and Wildlife
Service). Information on these rivers is also available at: http://www.rivers.gov/
28. The permittee must allow representatives from the Corps to inspect the authorized work at any
time deemed necessary to ensure that it is being or has been accomplished in compliance with
the terms and conditions of the permit.
29. The permittee shall maintain the activity authorized by this permit in good condition and in
conformance with the terms and conditions of this permit, including maintenance to ensure
public safety and compliance with applicable RGP general conditions, as well as any activity -
specific conditions added by the District Engineer to an RGP authorization. The permittee is not
relieved of this requirement if construction of the permitted activity is abandoned, although the
permittee may make a good faith transfer to a third party in compliance with General Condition
31 below. Should the permittee wish to cease maintenance of the authorized activity, or should
Page 11 of 14
Regional General Permit 12 Aquatic Habitat Improvement for Stream Channels
the permittee desire to abandon it without a good faith transfer, the permittee shall obtain a
modification of the permit from the Corps, which may require restoration of the area.
30. If the permittee sells the property associated with the permit verification, the permittee may
transfer the permit verification to the new owner by submitting a letter to the Corps to validate
the transfer. A copy of the permit verification must be attached to the letter, and the letter must
contain the following statement and signature: "When the structures or work authorized by this
permit are still in existence at the time the property is transferred, the terms and conditions of
this permit, including any special conditions, shall continue to be binding on the new property
owner(s). To validate the transfer of this permit and the liabilities associated with compliance
with its terms and conditions, have the transferee sign and date below."
BEST MANAGEMENT PRACTICES:
1. In order to prevent the spread of invasive and/or nuisance species (e.g., Asian Clam, Grand
Valley Asian Tapeworm, Green River Mud Snail, New Zealand Mud Snail), the permittee is
strongly encouraged to clean heavy equipment prior to and after construction if the equipment
was previously used in another stream, river, lake, pond, or wetland within 10 days of initiating
work. The following are recommended methods for preventing the spread of invasive aquatic
organisms:
• Remove all mud and debris from equipment (tracks, turrets, buckets, drags, teeth, etc.) and
spray/soak equipment with a 1:15 solution of disinfection solution containing the following
ingredients: - Dialkyl dimethyl ammonium chloride (5-10% by weight);
- Alkyl dimethyl benzyl ammonium chloride (5-10% by weight);
- Nonyl phenol ethoxylate (5-10% by weight);
- Sodium sesquicarbonate (1-5%); and,
- Tetrasodium ethylene diaminetetraacetate (1-15%)
The equipment should be kept moist for at least 10 minutes, and rinsate should be managed as
a solid waste in accordance with local, county, state, or federal regulations. Alternately,
equipment, hand tools, boots and any other equipment that was previously used in a river,
stream, lake, pond, or wetland prior to moving the equipment to another water body may be
disinfected using the following methods:
o Spray/soak equipment with water greater than 140 degrees Fahrenheit for at least 10
minutes.
o Sanitize water suction hoses and water transportation tanks (using methods described
above) and discard rinse water at an appropriately permitted disposal facility.
2. No petroleum products, chemicals, or other deleterious materials should be allowed to enter or
be disposed of in such a manner in which they could enter the waterway or adjacent wetlands.
Accordingly, it is recommended that oil absorbent "booms" be installed downstream of the
project site during construction activities.
Further Information:
1. District Engineers have authority to determine if an activity complies with the terms and
conditions of a RGP.
