Appendix E Required Design Features and Best Management Practices
Adverse environmental impacts associated with development can be avoided, reduced, or mitigated through the project’s design
and implementation. In the case of greater sage-grouse protections, in order to provide regulatory certainty that the measures
will be incorporated, they must be required of every project. The National Technical Team report identified management actions
and practices that would reduce adverse impacts to greater sage-grouse if mandated for development throughout either Core
Area (priority habitat), occupied greater sage-grouse habitat, or general habitat areas. Some of these practices are incorporated
as being universally appropriate. The ones that could be analyzed on a planning area-wide basis are identified in this appendix
as Required Design Features.
Other environmental protection measures could not be analyzed in a planning area-wide Environmental Impact Statement (EIS)
because their appropriateness depends upon site-specific issues such as proximity to the boundary of Core Area or non-crucial
habitat or engineering or physical limitations such as an oil and gas producing zone being too close to the surface to be
recoverable through directional drilling. These best management practices (BMPs) are required to be considered in a site-specific
project’s design to reduce, prevent, or avoid adverse environmental or social impacts. These practices are analyzed to help
ensure that development is conducted in an environmentally responsible manner. Some BMPs are as simple as choosing a paint
color that helps oil and natural gas equipment blend with the natural surroundings, making development less visible. Other
BMPs may reduce the amount of vegetation lost to development, improve the speed of re-growth of desirable vegetation, or may
reduce the amount of wildlife disturbance in important habitats. Public land users are encouraged to review these practices,
incorporate them where appropriate, or develop better methods for achieving the same goal. However, the Bureau of Land Management
(BLM) may also require their incorporation into the design features of the project as a condition of approval. Only when the
design feature is part of the BLM authorization as a condition of approval, should the National Environmental Policy Act (NEPA)
analysis of the project analyze the beneficial impacts of the design feature. If the practice is only voluntary or suggested,
the BLM lacks the authority to require its implementation, so the project should be analyzed as if the practice will not occur.
The BLM authorization will make clear whether the BMP is mandatory (attached as a condition of approval) or merely encouraged.
NEPA analysis that concludes that BMPs should not be attached as mandatory conditions of approval needs to clearly explain
why with relation to site-specific factors. The purpose of this section is not to select certain practices or designs and
require that only those be used. It is not possible to evaluate all the known practices and make determinations as to which
are best, particularly without a specific project in a specific location. BMPs should be matched and adapted to meet the
site-specific requirements of the decision, project, and local environment. No one management practice is best suited to
every site or situation, or will remain the most optimal practice over time. BMPs must be adaptive and monitored regularly
to evaluate effectiveness.
Protections for the greater sage-grouse are an important focal point in the preparation of the Resource Management Plan (RMP),
in part because of the importance of the Lander habitat for the survival and recovery of the species. Accordingly, a special
section of BMPs identifies management that should be considered in both greater sage-grouse Core Area and general greater
sage-grouse habitat. It is expected that these BMPs will change over time as monitoring and further study develop improved
greater sage-grouse protections.
Required Design Features
The following design approaches are required for all projects unless the proponent establishes that due to site limitations
or engineering considerations, the design approaches are infeasible. Economic considerations such as increased costs do not
render a design infeasible.
Greater Sage-Grouse Protection Required Design Features for All Projects:
The following measures, and others as they are identified, will be required for all BLM-authorized development. As appropriate,
they may be required as part of the design of the project or as a mandatory condition of approval. Other greater sage-grouse
protections are identified below as BMPs, which will be evaluated on a site-specific basis for inclusion as a mandatory condition
of approval.
General:
|
• |
In applying protections for greater sage-grouse, all projects must evaluate (1) whether the conservation measure is reasonable
(see 43 Code of Federal Regulations [CFR] 3101.1‐2 for the definition of “reasonable” for fluid mineral leases) and consistent
with valid existing rights, and (2) whether the action is in conformance with the RMP. Each conservation measure will be evaluated
on a site-specific basis for likely effectiveness on a cost-benefit basis. |
|
• |
In Core Area, where development would result in the long-term loss of greater sage-grouse habitat, identify effective mitigation
that will be applied for a sufficient term as to constitute replacement habitat. Example: Purchase private land and mineral
rights in the priority area and deed to the United States, or obtain a conservation easement in perpetuity. Consider compensatory
mitigation and monitoring of significant direct, indirect, and cumulative impacts on, and loss of habitat for, greater sage-grouse. |
|
• |
When additional mitigation is necessary, conduct it in Core Area, in the same greater sage-grouse population area. If Core
Area does not provide appropriate mitigation, conduct offsite mitigation in general greater sage‐grouse habitat with the ability
to increase greater sage‐grouse populations. |
|
• |
Designate a qualified biologist who will be responsible for overseeing compliance with all design features related to the
protection of ecological resources throughout all project phases, particularly in areas requiring avoidance or containing
concentrated greater sage-grouse populations. This person shall be approved by the BLM. |
Facilities and Surface Disturbance:
|
• |
Give overall consideration to minimizing the adverse impact to greater sage-grouse through a project design that avoids, minimizes,
reduces, rectifies, and/or adequately compensates for direct and indirect impacts to greater sage-grouse habitat or use. Apply
a phased development approach with concurrent interim reclamation. Locate and design individual project facilities to minimize
disruption of animal movement patterns and connectivity of habitats. |
|
• |
Subject to topographic and other environmental constraints, require development for a project wholly or partially in Core
Area to be placed in the area least harmful to greater sage-grouse based on vegetation, topography, or other habitat features. |
|
• |
Co-locate new development (facilities, pipelines, etc.) in existing disturbances or in areas where reclamation success has
not been fully achieved unless the proponent establishes that this is technically infeasible. Cluster disturbances, operations
(hydraulic fracture stimulation, liquids gathering, etc.), and facilities. Co-locate powerlines, flow lines, and small pipelines
under or immediately adjacent to existing roads. Design or site permanent structures to minimize impacts to greater sage‐grouse,
with emphasis on locating and operating facilities that create movement (e.g., pump jacks) or attract frequent human use and
vehicular traffic (e.g., fluid storage tanks) in a manner to minimize disturbance of greater sage-grouse or interference with
habitat use. |
|
• |
Locate new compressor stations outside priority habitats and require a design that reduces noise directed toward priority
habitat unless the proponent can establish that this requirement would preclude development of the lease. |
|
• |
Properly contain and promptly remove refuse to avoid attracting predators. |
|
• |
Use mats for drilling activities where topography permits to reduce vegetation disturbance, and as temporary roads between
closely spaced wells to reduce soil compaction and maintain soil structure to increase likelihood of vegetation reestablishment.
|
|
• |
Restrict the construction of tall facilities, distribution powerlines, fences, and other infrastructure to the minimum number
and amount needed. Place facilities, such as tanks, which could serve as greater sage-grouse predator perches, outside of
Core Area unless the proponent establishes that this is technically infeasible. Equip tanks and other aboveground facilities
with structures or devices that discourage nesting of ravens and raptors. |
|
• |
Site and/or minimize linear features to reduce disturbance and fragmentation of greater sage-grouse habitats. |
|
• |
Install greater sage-grouse safe fences around sumps, pits, and other trenching. |
|
• |
Evaluate whether the benefits to greater sage-grouse from burying powerlines would outweigh the potential loss of habitat
from the disturbance associated with burying the line, considering the potential threat from invasive nonnative species, low
reclamation potential, and other factors. If the benefits outweigh potential adverse impacts, require that the powerlines
be buried unless the applicant establishes that burying the lines is not technically feasible. |
|
• |
Use remote monitoring techniques for production facilities, where applicable, and develop a plan to reduce vehicular traffic
and human presence. |
|
• |
Properly contain and promptly remove refuse to avoid attracting predators. |
|
• |
Cover all fluid-containing pits and open tanks with netting (maximum 1.5-inch mesh size). |
|
• |
Locate all residential development for employees and contractors (“man camps”) outside of Core Area. |
|
• |
When a well is plugged and abandoned, avoid the use of above ground dry hole markers. |
Reclamation:
|
• |
Where native shrubs located on lands proposed to be disturbed are unique and desirable for interim and final reclamation purposes,
and the seed supply for these desirable brush species is not commercially available, seeds will be collected from the area
and stored using the procedures of the Seeds of Success program. Seedlings or plugs of common dominant species will be propagated,
preferably locally, in preparation for use in portions of area to be reclaimed to expedite vegetation recovery. |
|
• |
Maximize the area of interim reclamation on long‐term access roads and well pads, including reshaping, topsoiling, and revegetating
cut-and-fill slopes. |
|
• |
Identify areas of sustainable plant communities and populations appropriate for the project as sources for native plant material
and manage for use in reclamation and restoration work. Prioritize native seed allocation for use in priority greater sage‐grouse
habitat in years when preferred native seed is in short supply. |
|
• |
Utilize enhanced reclamation if needed to support more rapid interim and final reclamation including irrigation, mulching,
soil amendments, and erosion blankets. |
|
• |
When reseeding, use appropriate seed mixes and consider the use of appropriate subspecies of sagebrush seed. Continue to evaluate
seed mixtures over time, considering potential changes in climate (Miller et al. 2011) when proposing seedings using native
plants. Consider seed collections from the warmer component within a species’ current range for selection of native seed (Kramer
and Havens 2009). |
|
• |
Include reclamation or post-fire restoration objectives requiring that greater sage‐grouse habitat needs are adequately addressed,
and monitoring protocol to verify that the objectives are accomplished. Include greater sage‐grouse habitat parameters as
defined by Connelly et al. (2000), Hagen et al. (2007), or if available, state greater sage‐grouse conservation plans and
appropriate local information in habitat restoration objectives. Make maintaining these objectives in priority greater sage‐grouse
habitat areas a high restoration priority. |
|
• |
Identify and work with partners to increase native seed availability and work with plant material centers to develop new plant
materials, especially the forbs needed to restore greater sage-grouse habitat. |
|
• |
Choose native plant seeds for vegetation treatments based on availability, adaptation (site potential), probability for success,
and the vegetation management objectives for the area covered by the treatment. Prioritize native seed allocation for use
in Core Area in years when preferred native seed is in short supply. |
|
• |
Make reestablishment of sagebrush and desirable understory plant cover (relative to ecological site potential) a high priority
for restoration efforts. Write specific vegetation objectives to reestablish sagebrush cover and desirable understory cover. |
|
• |
Implement interim reclamation as soon as feasible for all disturbed soils to the side of roadways and other long-term disturbances,
reducing the disturbance to the smallest area possible. |
|
• |
Restore disturbed areas at final reclamation to the pre‐disturbance landforms and desired plant community. |
|
• |
Maximize the area of interim reclamation on long‐term access roads and well pads, including reshaping, topsoiling, and revegetating
cut-and-fill slopes. |
Impoundment Pond Design:
|
• |
Work with the Wyoming Department of Environmental Quality to limit surface discharge of water that has the potential of increasing
productivity for mosquitoes and decreasing greater sage-grouse habitat quality. |
|
• |
Identify permanent ponds so as to reduce the number of newly flooded sites, which have high productivity for mosquitoes. Avoid
flooding flat terrain or low-lying areas. |
|
• |
Design impoundment ponds to reduce attraction to breeding mosquitoes while considering attraction to other vectors of diseases
such as blue tongue disease. Design parameters should include steepness of sides, avoidance of shallows less than 2 feet
(60 centimeters), and reduction of rooted vegetation (both aquatic and uplands). |
|
• |
Separate inflow and outflow areas to produce open water; avoid creating wetlands. |
|
• |
Avoid down slope seepage or overflow (including from natural drainage). Line constructed ponds as necessary to avoid seepage.
Prevent shallow surface inflow and accumulation of sediment that promotes aquatic vegetation through piping discharge into
open water and lining channels. |
|
• |
Line the overflow spillway with crushed rock, and construct the spillway with steep sides to preclude the accumulation of
shallow water and vegetation. |
|
• |
Fence pond sites to restrict access by livestock and other wild ungulates that trample and disturb shorelines, enrich sediments
with manure, and create hoof print pockets of water that are attractive to breeding mosquitoes. |
|
• |
Treat waters with larvicides to reduce mosquito production where water occurs on the surface. |
Roads:
|
• |
Locate roads to avoid important habitats for greater sage-grouse and other wildlife. Construct, improve, and maintain access
roads to minimize potential wildlife/vehicle collisions and facilitate wildlife movement through the project area. |
|
• |
Apply dust abatement on roads, well pads, and other surface disturbances. Use of dust abatement with limited adverse impacts
to vegetation, cultural resources, water quality, and other resources. |
|
• |
When responding to a request for a road, develop a transportation plan on a landscape scale so as to consider all parties
who will be authorized to use the road. |
|
• |
Limit route construction to realignments of existing designated routes if that realignment has a minimal impact on greater
sage‐grouse habitat, eliminates the need to construct a new road, or is necessary for motorist safety. |
|
• |
Identify measures to reduce the use of motorized vehicles to reduce adverse impacts to wildlife. |
|
• |
Design roads to minimize total disturbance to the smallest amount possible and to the lowest standard while meeting road objectives
or purpose including safety. Establish speed limits that will reduce vehicle speed to reduce greater sage-grouse mortality. |
|
• |
If road crossings of linear water features (such as ephemeral, intermittent, and perennial streams) cannot be avoided, construct
crossings to minimize impacts to the riparian-wetlands habitat. Usually this will mean crossing the feature at right angles.
Temporary, portable bridges should be considered. |
|
• |
Limit the use of new roads associated with development including not making it part of the public road network or implementing
seasonal closures. Restrict motorized vehicle use to authorized users using signage, gates, and other devices. |
|
• |
Establish slow speed limits on BLM-administered roads or design roads for slower vehicle speeds to reduce greater sage-grouse
mortality and other wildlife conflicts. |
|
• |
During travel management implementation, close and rehabilitate duplicate roads and rights-of-way (ROWs) no longer being utilized.
When restoring original landform and establishing desirable vegetation, use appropriate seed mixtures or transplants as provided
above and in Appendix B Reclamation Objectives and Standards. Identify roads where the risk of vehicle or human‐caused wildfires and the spread of invasive species into greater sage-grouse
habitats could be minimized by planting perennial vegetation (e.g., green‐strips) paralleling road ROWs (this BMP could be
applied to BLM linear ROW authorizations). |
Fire:
|
• |
Prior to the fire season, provide greater sage-grouse training to resource advisors. |
|
• |
Develop site‐specific greater sage‐grouse reference information and resource materials containing maps, a list of resource
advisors, contact information, local guidance, and other relevant information. Provide localized maps to dispatch offices
and extended attack incident commanders for use in prioritizing wildfire suppression resources and designing suppression tactics.
Involve state wildlife agency expertise in fire operations through: instructing resource advisors during preseason trainings;
qualification as resource advisors; coordination with resource advisors during fire incidents; and contributing to incident
planning with information such as habitat features or other key data useful in fire decision making. The BLM has collected
wildfire data considered to be reliable since 1960. Although perimeter mapping was not instituted until recently, acreage
estimations were made and linked to a point or polygon on a map. Using Geographic Information System analysis cross linking
the acres with the points or the actual mapped locations where available, the BLM determined that a total of 25,000 acres in Core Area were burned by wildfire, less than 0.15 percent of Core Area. |
|
• |
During periods of multiple fires, ensure line officers are involved in setting priorities. |
|
• |
Locate wildfire suppression facilities (i.e., base camps, spike camps, drop points, staging areas, and heli‐bases) in areas
where physical disturbance to greater sage‐grouse habitat can be minimized. These include disturbed areas, grasslands, near
roads/trails, or in other areas where there is existing disturbance or minimal sagebrush cover. |
|
• |
Where applicable, utilize retardant and mechanized equipment to minimize burned acreage in Core Area during an extended attack.
Utilize retardant, mechanized equipment, and other available resources to minimize burned acreage during initial attack. |
|
• |
As safety allows, conduct mop‐up where the black adjoins unburned islands, dog legs, or other habitat features to minimize
sagebrush loss. |
|
• |
Minimize burnout operations in Core Area or near a lek outside of Core Area (with input from the resource adviser) by constructing
direct fireline whenever safe and practical to do so. |
|
• |
Minimize unnecessary cross‐country vehicle travel during fire operations in greater sage‐grouse habitat. |
|
• |
Adequately document fire operation activities in greater sage-grouse habitat for potential follow-up coordination activities.
|
|
• |
Power-wash all firefighting vehicles, to the extent possible, including engines, water tenders, personnel vehicles, and all-terrain
vehicles prior to deploying in or near greater sage-grouse habitat areas to minimize spread of invasive plants. |
Vegetation Treatment and Fuels Management:
|
• |
Design vegetation treatments in areas of high wildfire frequency to facilitate firefighter and public safety; reduce the risk
of extreme fire behavior; and reduce the risk and rate of fire spread to greater sage-grouse habitats while facilitating the
restoration of key habitats. |
|
• |
Design fuels treatment objectives to protect existing sagebrush ecosystems, modify fire behavior, restore native plants, and
create landscape patterns that most benefit greater sage-grouse habitat. |
|
• |
Provide training to fuels treatment personnel on greater sage-grouse biology, habitat requirements, and identification of
areas utilized locally. |
|
• |
Use fire prescriptions that minimize undesirable effects on vegetation or soils (e.g., minimize mortality of desirable perennial
plant species and reduce risk of hydrophobicity). |
|
• |
Incorporate roads and natural fuel breaks into fuel-break design. |
|
• |
Power wash all vehicles and equipment involved in fuels management activities prior to entering the area to minimize the introduction
of undesirable and/or invasive plant species. |
|
• |
Outside of priority habitat, give priority for implementing sagebrush restoration projects that are adjacent to priority habitat. |
|
• |
As funding and logistics permit, restore habitat to a species composition characterized by perennial grasses, forbs, and shrubs. |
|
• |
Do not reduce sagebrush canopy cover to less than 15 percent within a treatment polygon unless a vegetation management objective
requires additional reduction in sagebrush cover to meet strategic protection of priority greater sage‐grouse habitat and
conserve habitat quality for the species. |
|
• |
Ensure proposed sagebrush treatments are planned with interdisciplinary input from BLM and state wildlife agency biologists,
and that treatment acreage is conservative in the context of surrounding greater sage-grouse seasonal habitats and landscape. |
|
• |
In suitable greater sage-grouse habitat, the priority for vegetation treatments are those that conserve, enhance, or restore
greater sage‐grouse habitat, reduce fuels at strategic locations to minimize the size of wildfires and limit loss of greater
sage-grouse habitat. Remove conifers where they have encroached upon greater sage-grouse habitat. Reduce the density of conifers
that have encroached into, but do not yet dominate, sagebrush plant communities. |
|
• |
Minimize undesirable effects on vegetation or soils (e.g., minimize mortality of desirable plant species and reduce risk of
hydrophobicity). Incorporate vegetation treatment standard operating procedures, such as those outlined in the 17 Western
States Vegetation Programmatic EIS, into treatments (BLM 2007b). |
|
• |
Ensure that treatments are configured in a manner (e.g., strips) that promotes use by greater sage‐grouse. |
|
• |
Reestablish appropriate sagebrush species/subspecies and important understory plants relative to site potential. Identify
priority plant species and collect seed of understory plants and sagebrush subspecies important to greater sage-grouse. Establish
seed harvest areas that are managed for seed production and are a priority for protection from outside disturbances. |
|
• |
Design vegetation treatments in greater sage-grouse habitats to strategically reduce wildfire threats in the greatest area.
This could involve spatially arranging new vegetation treatments with past treatments, vegetation with fire-resistant serial
stages, natural barriers, and roads to constrain fire spread and growth. This could require vegetation treatments to be implemented
in a more linear versus block design. |
|
• |
Remove standing and encroaching trees within at least 100 meters of occupied greater sage‐grouse leks and other habitats (e.g.,
nesting, wintering, and brood-rearing) to reduce the availability of perch sites for avian predators. |
|
• |
Protect wildland areas from wildfire originating on private lands, infrastructure corridors, and recreation areas. |
|
• |
Strategically place and maintain pretreated strips/areas (e.g., mowing, prescribed fire, herbicide application, and strictly
managed grazed strips) to aid in controlling wildfire should wildfire occur near key habitats or important restoration areas
(such as where investments in restoration have already been made). |
Mineral Development:
|
• |
Give overall consideration to impacts to greater sage-grouse in applying technically feasible conditions of approval. Selection
and application of these measures shall be based on current science and research on the effects to important breeding, nesting,
brood-rearing, and wintering areas. The Plan of Development or Plan of Operations, as applicable, shall address, at a minimum,
the anticipated noise, density and amount of disturbance, mechanical movement (e.g., pump jacks), permanent and temporary
facilities, traffic, phases of development over time, offsite mitigation, and expected periods of use associated with the
proposed project. The NEPA analysis and authorization should identify seasonal habitats or typical project features related
to potential greater sage-grouse impacts, such as drill mats that are not made a part of the conditions of approval, based
on site-specific or project-specific considerations and the explanation of why these protections were not included. |
|
• |
Where feasible, co-locate new development (facilities, pipelines, etc.) in existing disturbances. Cluster disturbances, operations
(hydraulic fracture stimulation, liquids gathering, etc.), and facilities. Use drilling techniques to reduce surface disturbance
in relation to the number of wells, where feasible. Place liquid-gathering facilities and compressor stations outside Core
Area, unless the proponent can establish that this requirement would preclude development of the lease. Identify measures
to reduce traffic in Core Area. |
|
• |
To ensure comprehensive planning relative to greater sage-grouse conflicts, complete Master Development Plans or Plans of
Development during planning and review of projects involving multiple proposed disturbances in Core Area. |
|
• |
In Core Area, require closed‐loop systems for drilling operations, with no reserve pits unless technically infeasible. |
|
• |
Require noise shields or other noise abatement devices when drilling during the lek, nesting, brood-rearing, and wintering
seasons. Locate new compressor stations outside of Core Area if feasible, and require a design directed toward priority habitat
that reduces noise. |
Miscellaneous:
|
• |
Identify areas where acquisitions (including subsurface mineral rights) or conservation easements, would benefit greater sage‐grouse
habitat. Apply acquisition and disposal criteria from Appendix K Lands Identified for Disposal. |

Forestry Best Management Practices
Road Construction and Maintenance: The need for higher-standard roads can be alleviated through temporary road blockage, locked gate management, and seasonal
weather restrictions.
Number of Roads, Existing Roads: Minimize the number of roads constructed in a watershed through comprehensive road planning, recognizing intermingled ownership
and foreseeable future uses to avoid the creation of sediment, change of water temperature, or addition of unwanted nutrients.
Use existing roads where practical, unless use of such roads would cause or aggravate an erosion problem. When using existing
roads, reconstruct only to the extent necessary to provide adequate drainage and safety; avoid disturbing stable road surfaces.
Road Design and Implementation: Fit the road to the topography by locating roads on natural benches and following natural contours. Locate roads on stable
geology, including well-drained soils and rock formations that tend to dip into the slope. Avoid slumps and slide-prone areas
characterized by steep slopes, toe slopes, natural drainage channels, highly weathered bedrock, clay beds, concave slopes,
and hummocky topography, and rock layers that dip parallel to the slope. Avoid wet areas, including moisture-laden or unstable
toe slopes, seeps, wetlands, wet meadows and natural drainage channels. Minimize earth-moving activities when soils appear
excessively wet.
Drainage: Design roads to minimize disruption of natural drainage patterns. Provide adequate drainage, as part of the construction process,
from the surface of all permanent and temporary roads. Design, install, and route road surface drainage features at adequate
spacing to control erosion; steeper gradients require more frequent drainage features. Install road-drainage features above
stream crossings to route discharge into filtration zones before it enters a stream or surface water. Use outsloped, insloped,
or crowned roads and space road-drainage features so peak drainage flow on the road surface or in ditches will not exceed
capacity. Provide energy dissipaters (rock piles, slash, log chunks, etc.) where necessary to reduce erosion at the outlet
of drainage features. Cross drains, culverts, water bars, dips, and other drainage structures should not discharge onto erodible
soils or fill slopes without outfall protection. Properly constructed drain drips can be an economical method of road surface
drainage. Construct drain dips deep enough into the subgrade so that traffic will not obliterate them. Route road drainage
through adequate filtration zones or other sediment settling structures to ensure sediment does not reach surface water.
Runoff/Erosion Control: Stabilize erodible, exposed soils by seeding, compacting, rip-rapping, benching, mulching, or other suitable means prior to
seasonal runoff. Prevent downslope movement of sediment by using sediment catch basins, drop inlets, changes in road grade,
headwalls, or recessed cut slopes. Keep slope stabilization, erosion, and sediment control work current with road construction.
Complete or stabilize road selections within the same operating season. Maintain erosion-control features through periodic
inspection and maintenance, including cleaning dips and cross drains, repairing ditches, marking culvert inlets to aid in
location, and clearing debris from culverts.
Debris and Excess Material Handling: Haul all excess material removed by maintenance operations to safe disposal sites and stabilize these sites to prevent erosion.
Avoid sidecasting and place debris, overburden, and other waste materials associated with construction and maintenance activities
in a location to avoid entry into streams. Include these waste areas in soil stabilization planning for the road. Minimize
sediment production from borrow pits and gravel sources through proper location, development, and reclamation.
Cut and Fill Slopes: This includes: construct cut and fill slopes at stable angles to prevent sloughing and other subsequent erosion. Design roads
to balance cuts and fills or use full bench construction (no fill slope) where stable fill construction is not possible. Avoid
incorporating potentially unstable woody debris in the fill portion of the road prism. Where possible, leave existing rooted
trees or shrubs at the toe of the fill slope to stabilize the fill. At the toe of potentially erodible fill slopes, particularly
near stream channels, pile slash in a row parallel to the road to trap sediment. When done concurrently with road construction,
this is one method that can effectively control sediment movement, and it can provide an economical way of disposing of roadway
slash. Limit the height, width, and length of “slash filter wind-rows” so wildlife movement is not impeded. Sediment fabric
fences or other methods may be used if effective.
Out/In Slopes: Outsloped roads provide a means of dispersing water in a low-energy flow from the road surface. Outsloped roads are appropriate
when fill slopes are stable, drainage will not flow directly into stream channels, and transportation safety can be met. For
insloped roads, plan ditch gradients steep enough, generally greater than 2 percent but less than 8 percent, to prevent sediment
deposition and ditch erosion. The steeper gradients may be suitable for more stable soils; use the lower gradients for less
stable soils. Do not disturb roadside vegetation more than necessary to maintain slope stability and serve traffic needs.
Weather Maintenance: Grade road surfaces only as often as necessary to maintain a stable running surface and adequate surface drainage. Avoid
cutting the toe of cut slopes when grading roads, pulling ditches, or plowing snow. When plowing snow, provide breaks in the
snow berm to allow road drainage. Consider gates, barricades, or signs to limit use of roads during spring breakup to other
wet periods. Avoid using roads during wet periods if such use would likely damage the road drainage features. When access
requires crossing moist areas with a poor road base, cross only when the ground is frozen or dry to alleviate a rutted, poorly
drained road. Upon completion of seasonal operations, ensure that drainage features are fully functional. The road surface
should be crowned, outsloped, insloped, or waterbarred. Remove berms from the outside edge.
Ditch Culverts: For ditch relief culverts, construct catch basins with stable side slopes. Protect the inflow end of cross drain culverts
from plugging and armor if in erodible soil. Where possible, install culverts at the gradient of the original ground slope;
otherwise armor outlets with rock or anchor downspouts to carry water safely across the fill slope. Skew ditch relief culverts
20 to 30 degrees toward the inflow from the ditch to help maintain proper function.
Stream Culverts: When using culverts to cross small streams, install those culverts to conform to the natural stream bed and slope on all intermittent
streams that support fish or that provide seasonal fish passage. Ensure fish movement is not impeded by using culverts with
a suitable diameter for permanent stream crossings and during peak flows. Maintain a 1-foot minimum cover for culverts 15
to 36 inches in diameter, and a cover of one-third diameter for larger culverts to prevent crushing by traffic. Place culverts
slightly below normal stream grade to avoid culvert outfall barriers. Do not alter stream channels upstream from culverts,
unless necessary to protect fill or to prevent culvert blockage. Install culverts to prevent erosion of fill. Compact the
fill material to prevent seepage and failure. Armor the inlet and/or outlet with rock or other suitable material where feasible.
Consider dewatering stream-crossing sites during culvert installation. This can be done with a temporary diversion channel
or a sandbag dam with a pump diversion.
Stream Crossings: Minimize the number of road stream crossings and choose stable stream-crossing sites. Minimize stream-channel disturbances
and related sediment problems during necessary construction of road and installation of stream-crossing structures. Whenever
possible, retain existing vegetation and organic material around stream crossings. Locate temporary construction bypass roads
where the stream course will have minimal disturbance. Design stream crossings for adequate passage of fish (if present) and
time construction activities to have minimum impact on water quality and fisheries. Consider oversized pipe when debris loading
may pose problems. Ensure sizing provides adequate length to allow for depth of road fill. Do not place erodible material
into stream channels and remove stockpiled material from high-water zones. Abutments and wingwalls should prevent material
from spilling into the stream. Avoid unimproved stream crossings. When a culvert or bridge is not feasible, locate drive-through
(ford) on a stable, rocky portion of the stream channel, such as a bedrock stream.
Equipment Use: Avoid operation of wheeled or tracked equipment within isolated wetlands, except when the ground is frozen. Tractor skid where
compaction, displacement, and erosion will be minimized. Avoid tractor or wheeled skidding on unstable wet or easily compacted
soils.
Hazardous Substances/Weed and Pest Control: Know and comply with regulations governing the storage, handling, application (including licensing of applicators), and disposal
of hazardous substances. Follow all label instructions. Develop a contingency plan for hazardous substance spills, including
cleanup procedures and notification of the Wyoming Department of Environmental Quality (DEQ). A Spill Prevention and Countermeasures
Plan is required by federal law for storage of more than 1,320 gallons, and state law requires the reporting of spills over
25 gallons.
Integrated Approach: Use an integrated approach to weed and pest control, including manual, biological, mechanical, preventative, and chemical
means. To enhance effectiveness and prevent transport into streams, apply chemicals during appropriate weather conditions
(generally calm and dry) and during the optimum time for control of the target pest or weed.
Prescribed Burning and Wildfire Suppression: Protect soil and water from prescribed burning effects by maintaining soil productivity, minimizing erosion, and preventing
ash, sediments, nutrients and debris from entering surface water. After an intense wildfire or prescribed burn, emergency
rehabilitation may be necessary to minimize the loss of soil, prevent the deterioration of water quality, and to mitigate
threats to life and property. Stabilize all areas that have significantly increased erosion potential or drainage patterns
altered by suppression activities by installing water bars and other drainage diversions in fire roads, fire lines, and other
cleared areas, seeding, planting, and fertilizing to provide vegetative cover, spreading slash or mulch to protect bare soil,
repairing road damage, and clearing stream channels of debris deposited by suppression activities and scarification as necessary
to encourage percolation on excessively burned soils.
BMPs for Water Resources
BMPs would be appropriate for consideration when proposed activities are within groundwater zones 1-3, surface water zones
1-3, and sensitive aquifer systems identified through the use of the Wyoming Groundwater Vulnerability Assessment Handbook
(Wyoming DEQ 2004), or similar document updated over time. BMPs to mitigate impacts to water resources include, but are not
limited to, the following:
|
• |
Use closed-loop drilling systems where technologically feasible. |
|
• |
Reuse produced water for well completion activities and enhanced oil recovery operations using water. |
|
• |
Do not use evaporation ponds or reserve pits in proximity to shallow aquifers. Reduce reliance on evaporation ponds in other
locations and other forms of surface disposal. |
|
• |
Line surface impoundment ponds (evaporation ponds or drilling pits) with synthetic liners and subsequently decommission them
by removing all contaminants and liners, and reclaiming the area. |
|
• |
Identify private water supply wells and implement appropriate protection measures for the affected aquifer(s), as necessary
to prevent the introduction of contaminants into the well (e.g., site oil and gas wells at a distance necessary to prevent
the introduction of contaminants into the drinking water supply well, collect baseline water quality data from the water supply
well, etc.). |
|
• |
Require a monitoring plan that includes collection of baseline and periodic water quality data from potentially affected drinking
water supply wells, identification of parameters to monitor, reporting results to the BLM and well owners, and reporting to
Wyoming DEQ any contaminant in groundwater exceeding Wyoming DEQ (or Environmental Protection Agency) Class I drinking water
standards. |
|
• |
Review the geology of shallow aquifers to determine well construction requirements, which may include cementing to surface
and drilling with a fresh water mud system. |
|
• |
Require surface casing and cement to a specific formation or depth to protect aquifers at depth that need protection. |
|
• |
Set surface casing below the lower-most drinking water and set into a confining (e.g., shale) layer. |
|
• |
Set an intermediate string of casing and cement in the event of deep aquifers. |
|
• |
Require submittal of a well logging plan and document submittal plan to ensure proper well construction to protect groundwater. |
|
• |
Review the geology of shallow aquifers in proximity to groundwater development activities to determine potential impacts to
flow patterns supporting water elements such as fen, wetlands, springs, seeps, and ponds. |
|
• |
Because of the age of the well or depth or other factor, require re-completions to comply with state and federal standards
for new well construction; analyze cement bond logs associated with any existing well location within ¼-mile of completing
a new well or re-completing an existing one; and identify how re-completed wells will be tested and monitored. |
BMPs for Greater Sage-Grouse Protections
Knowledge of BMPs for greater sage-grouse protections is an evolving field. As research is done on impacts of various kinds
of activities, or the absence thereof, on greater sage-grouse, additional protections will be identified. While some of these
will be generic enough to be applied planning area-wide, others will require site-specific analysis to determine if they are
appropriate for inclusion as a mandatory condition of approval. This BMP section of this appendix will be supplemented as
technology and understanding of greater sage-grouse advance.
