PART 2 - PRODUCTS (Not Used)

PART 3 - EXECUTION (Not Used)

END OF SECTION 01 11 00

Revised 28 March 2018

Grand Teton National Park (GRTE) John D. Rockefeller, Jr. Memorial Parkway (JODR) Standard Mitigations and Stipulations

NOTE: Some projects and activities are proposed by non-National Park Service (NPS) individuals, groups, partners, officials, agencies, organizations, businesses, etc. These proposals are usually initiated through a special use permit request or are part of an agreement, contract, commercial authorization, or other signed record between the NPS and the non-NPS entity. In these cases, the appropriate NPS employee will serve as the Project Leader and “liaison” to ensure proper compliance procedures are being followed. The “liaison” will be the contact with the non-NPS entity.

The Project Leader is responsible for ensuring the following mitigations and stipulations are followed. The non-NPS entity will contact the NPS Project Leader if any of the mitigations and stipulations reference a specific phone number below. The Project Leader will contact the referenced office or individual and will advise the non-NPS entity.

Congress charged the NPS with managing the lands under its stewardship “in such manner and by such means as would leave them unimpaired for the enjoyment of future generations” (NPS Organic Act, 16 USC 1). As a result, NPS staff routinely evaluate and implement mitigation measures whenever conditions occur that could adversely affect the sustainability of national park system resources.

Mitigation is defined in the Code of Federal Regulations (40 CFR 1508.20) as:

• Avoiding the impact altogether by not taking a certain action or parts of an action.

• Minimizing impacts by limiting the degree or magnitude of the action and its implementation.

• Rectifying the impact by repairing, rehabilitating, or restoring the affected environment.

• Reducing or eliminating the impact over time by preservation and maintenance operations during the life of the action.

• Compensating for the impact by replacing or providing substitute resources or environments.

The following mitigation measures were developed to minimize the degree and/or severity of adverse effects and would be implemented as appropriate during approved project activities. The NPS may need to obtain federal and state environmental permits and, as part of that process, additional mitigation measures could be required by other agencies.

Assessment of Effect

• If previously unknown archeological resources and/or human remains are discovered during construction, all work in the immediate vicinity (600 feet) of the discovery shall be halted until the resources are identified and documented and an appropriate mitigation strategy developed. Contact the Branch Chief of Cultural Resources (307-739-3671).

Assessment of Effect – Cultural Landscapes

• All vegetation modification, including tree removal, at National Register of Historic Places -listed or -eligible properties shall be reviewed and approved by the Section 106 specialists (as well as by wildlife and vegetation specialists).

Attachment 1.10.A (10 pages)

• All work on or near historic buildings, structures, sites, and landscapes shall be conducted in accordance with the Secretary of the Interior's Standards for the Treatment of Historic Properties in consultation with the Branch Chief of Cultural Resources (307-739-3671). Any deviation from the approved specifications must be submitted for further review.

Assessment of Effect – Historic Structures

• All work on or near historic buildings, structures, sites, and landscapes shall be conducted in accordance with the Secretary of the Interior's Standards for the Treatment of Historic Properties in consultation with the Branch Chief of Cultural Resources (307-739-3671). Any deviation from the approved specifications must be submitted for further review.

• Consult with NPS cultural resource specialists or archaeologists in advance (generally 60 days) of any ground disturbing activities or work on or near buildings, structures, sites and landscapes eligible for or determined eligible for listing in the National Register of Historic Places.

• Inform all contractors and subcontractors of the penalties for illegally collecting artifacts or intentionally damaging archeological sites or historic properties.

Night Sky

• Project shall comply with NPS lighting guidelines to reduce impacts to the night sky and wildlife. This will include, but is not limited to, low-level lighting, minimized glare, downward focused light fixtures, and energy efficient light sources.

Park Operations & Mgmt – Aviation

• The following stipulation applies to all unmanned aircraft and aircraft managed by the Department of the Interior and Department of Agriculture in accordance with the Teton Interagency Aviation Management Plan. Coordinate all aircraft activities including unmanned aircraft with the Park's Interagency Aviation Officer (307-739-3339/5524) at least 30 days in advance. Flight requests or flight schedules should be submitted to the Aviation Officer by the requestor and be returned to the requestor if approved from Teton Interagency Dispatch. Flight requests or flight schedules for nonemergency missions need to be submitted allowing enough time for approval of project aviation safety plans, aircraft selection or procurement, and selection of aircraft management and necessary support personnel.

• The following stipulation applies to manned aircraft activities not directly managed by Teton Interagency Aviation and that require a special use permit or scientific research permit. For each day of activity where any type of aircraft is used the permit holder or aircraft operator shall contact Teton Interagency Dispatch (307-739-3630) prior to and at the end of the operation.

Park Operations & Mgmt – Construction General

• Hours of work may be determined by the park to avoid construction disturbance to visitors, park residents, or wildlife.

• The location of all potential utility lines in work areas shall be field located and marked prior to work to avoid disturbance conflict.

• Maintain a safe construction zone. Fence around open holes when personnel are not present and provide for a slope out of the hole such that wildlife trapped in the excavation may be able to escape.

• Control dust during construction by minimizing soil exposure, watering, and using other dust prevention methods.

Attachment 1.10.A

• Dispose of construction and/or demolition debris (e.g., old water lines, appurtenances, water tanks, valves, packaging materials, trash) at appropriate areas designated by the park. When possible, debris will be disposed of at a materials recycling facility.

• All project zones will be kept trash free at all times.

• To minimize the amount of ground disturbance, staging and stockpiling areas will be located in previously disturbed sites, away from visitor use areas to the extent possible. All staging and stockpiling areas shall be returned to pre-construction conditions following project completion.

Parking of construction vehicles will be limited to these staging areas, existing roads, and previously disturbed areas.

• Identify and define construction zones with construction tape, snow fencing, or other material prior to any construction activity. Use the zone to confine activity to the minimum area required for construction. Construction activities, including material staging and storage, cannot occur beyond the construction zone fencing.

• A traffic control plan for use during construction as approved by the park will be developed and enforced to minimize disruption to visitors and park operations and to ensure safety of the public, park employees, and residents.

Park Operations & Mgmt - Communications

• Inform contractors (construction workers and supervisors) about the special sensitivity of park values, regulations, and appropriate housekeeping.

• Contractors will coordinate with park staff to minimize disruption of normal park activities.

• If the project or activity occurs within or immediately adjacent to park housing areas, coordinate with the park's Housing Program Manager (307-739-3577) at least one week before the project or activity is scheduled to begin and immediately after it is completed.

Park Operations & Mgmt - Utilities

• Notify Park Facilities Management Utility Systems staff (307-739-3366) prior to a contractor connecting to or repairing a water or sewer line in the park. Any repairs to potable water lines must be coordinated with the park, and any potable water line that loses pressure during construction will be required to be placed into Boil Order status until a sample can be collected and tested.

• Following construction, furnish the GRTE GIS Office (307-739-3493) with utility location information, including a shapefile using coordinates NAD83 UTM 12N, company name, and type and number of lines.

Soils, Topography, Geology – Construction

• Avoid rutting or excessive soil compaction caused by vehicles or equipment. Construction activities shall be restricted during saturated soil conditions or severe weather conditions to avoid damage to soils and vegetation. In the event of adverse weather conditions, the project leader will consult with the SRM Vegetation Branch (307-739-3678) to ensure that ground conditions are acceptable for project activities.

Soils, Topography, Geology – Disturbance

• To minimize the amount of ground disturbance, locate staging and stockpiling areas in previously disturbed sites to the extent possible. Return all staging and stockpiling areas to pre-construction conditions following construction.

Soils, Topography, Geology – Erosion Control

• To minimize soil loss/erosion at the project site, erosion control best management practices (BMPs) including protection measures such as sediment traps, silt fences, erosion check screens/filters, jute mesh, will be used if necessary, to prevent the loss of soil.

Soils, Topography, Geology – Topsoil

• Topsoil should be salvaged at the beginning of all ground disturbance activities by scraping the topsoil to the side prior to deeper digging. Topsoil refers to the uppermost layers of soil and includes fine particles, small roots, rocks, and cobbles. It is usually darker in color, and is the layer in which the majority of roots grow and beneficial microorganisms exist. It is usually the top 2-6 inches.

Conserving topsoil will minimize impacts to vegetation and help preserve valuable micro-organisms and the native seed bank.

• Store salvaged topsoil separately from other materials. Limit the height of topsoil stockpiles to 36 inches. Do not stockpile topsoil or subsoil within drip line of remaining trees. Excess soil will be stored only at approved locations.

• Replace topsoil and other excavated soils and rock in the proper order, cobble lowest, then subsoil, then topsoil. Use a trench box if one is needed to reduce disturbance. Spread topsoil as near to the original location as possible.

• During the final stages of project implementation, scarify and loosen compacted subsoils to a minimum depth of 12 inches prior to replacing the salvaged topsoil. Soil decompaction will be done with equipment that has ripping teeth, placed a maximum of 12 inches apart.

• Do not drive or operate equipment on newly replaced topsoil. Do not re-enter the project site once revegetation/restoration work has been initiated and/or completed.

Soundscapes-Idling

• To reduce noise and pollution emissions, construction equipment and all motor vehicles will not idle any longer than is necessary.

Soundscapes-Mufflers

• Ensure that motorized vehicles and equipment have properly functioning mufflers.

Vegetation

• Coordinate all project work with park vegetation specialists regarding invasive, non-native plant

(weed) treatments, revegetation requirements, costs, and scheduling. Contact the SRM Vegetation Branch (307-739-3678).

• Limit ground disturbance to the smallest area possible to reduce disturbance to soil and native plants and reduce the potential for the introduction and/or spread of non-native, invasive plant species.

• Plant survey for rare and/or sensitive species are required prior to ground disturbing activities and must be conducted during growing seasons when these species could be identified.

Vegetation – Exotic Plants

• Seed mixes used for revegetation in roadside corridors will be composed of native species and approved by SRM Vegetation Branch staff.

• Prior to project implementation, SRM Vegetation staff will conduct invasive, nonnative plant surveys in the project area. Invasive weed control measures will be implemented to monitor and mitigate impacts within the first 3 years (minimum) of construction.

• To reduce the threat of nonnative, invasive vegetation being introduced to the park, all imported material (i.e., sand, gravel, rock, rip-rap, etc.) must be obtained from a park approved or county weed district approved source. Teton County Weed and Pest has currently approved as weed-free the various Evans Construction pits in Teton County. If a new material source is requested, park vegetation staff will seek county-approved material source pits and/or perform a nonnative, invasive plant inspection.

• Material sources, including sand, gravel, rock, rip-rap, mulch, etc. that is not attained form a county or park approved weed-free material sources must be precooked (300 degrees) or washed to prevent spread on invasive weeds in the park.

Vegetation – Miscellaneous

• Vegetation beyond the estimated scope of disturbance shall not be damaged or removed without prior approval via the project documents or by park vegetation management staff.

• To facilitate revegetation and non-native, invasive plant management, provide the SRM Vegetation Branch (307-739-3678) via project documents, with an estimate of potential ground disturbance at least 4 weeks prior to work and with the dimensions of the disturbed area after the work is complete.

• Consider minimizing ground and vegetation disturbance by boring or other alternatives to trenching activities.

• Use wooden mats for vehicle and equipment access to the site to limit damage to existing vegetation.

• Avoid destruction of individuals or populations of sensitive plant species or alteration of their habitat when conducting ground disturbing activities. SRM vegetation staff will notify project managers of rare or sensitive plant species for project documents prior to initiation of activities.

• For roadside brush removal activities, parts under 3" in diameter may be "lopped and scattered" into adjacent forested vegetation so that it is 6 inches or less in depth measured immediately after treatment. If chipping, broadcast chips so that chip depth is less than 2 inches measured immediately after treatment.

Vegetation - Trees

• Preserve existing trees to the extent possible, and during trenching operations, avoid damaging the roots of nearby trees.

• Tree/ Slash Removal - When trees are felled as part of project right of way clearing, remove all tree parts greater than 3” in diameter from the site except those pieces (“slash”) needed for revegetation or reclamation of the disturbance. The limbs, tops, and miscellaneous residue left by forest thinning and pruning activities are commonly called slash.

• Tree/ Slash Removal - Tree parts (slash) under 3" in diameter (not chips) may be "lopped and scattered" into adjacent forested vegetation so that it is 6 inches or less in depth measured immediately after treatment. If the <3" slash is chipped, broadcast the chips so that chip depth is less than 2 inches measured immediately after treatment. Chips may also be removed from the park for other uses.

• Stumps resulting from tree removal shall be flush cut level with the ground and no higher than 2” as measured from the uphill side.

Vegetation – Weed/Seed Free

• If a material source does not have an approval for weed-free, or if a material source fails an inspection, then the material must be clean of weed seed materials and dirt debris before entering the park. That typically entails cooking material such as sand and gravel to 300 degrees F. For larger rock and rip-rap, the rock can be separated from smaller dirt materials, and washed prior to entering the park.

• All vehicles and equipment shall arrive at the job site in a condition free of mud, dirt, and plant material. A method such as pressure washing prior to transport will be needed to comply with this requirement. Prior to offloading of any equipment, inspection and verbal approval must be obtained from the park resource management representative or delegated representative. The spread of non-native, invasive plant species in the park is a serious concern, and no equipment will be allowed to offload or remain within the park if dirt or other contaminants with the potential to harbor seeds or other plant material is apparent.

Fish and Wildlife

• Work that includes influence or direct disturbance to a wetland or stream should not be conducted during fish spawning periods. Spawning phenology by species is dependent on location of waterway, so please contact the SRM Fish and Wildlife Branch Fisheries Biologist (307-739-3666) for specifics.

• Consult with SRM Fish and Wildlife biologists (307-739-3666) regarding culvert design to allow for fish and wildlife passage where applicable.

• To prevent introduction of terrestrial or aquatic invasive species, all equipment, including rubber-tired land and tracked land vehicles, construction and facility equipment, watercraft, and personal use equipment such as diving gear, must be thoroughly cleaned, and inspected by park personnel before being operated or launched in the park.

• Unless otherwise noted (i.e., elk rutting and near sage grouse leks), limit routine construction activities to 30 minutes after sunrise to 30 minutes prior to sunset to avoid disturbance to wildlife.

• To protect special status species:

o Inform staff about the potential for special status species in or near the area of the proposed activity. Work will cease if a special status species is discovered in the project area, until park staff re-evaluates the project. Protective measures, including potential modification of the work or the work schedule, could be determined necessary.

o Ensure that all mitigations/conservation measures determined through Endangered Species Act Section 7 consultation with the U.S. Fish and Wildlife Service (USFWS) are followed.

o In circumstances when it is deemed necessary to conduct activities near sites known to support threatened or endangered species, such work will be performed in a way (specified by the park biologist) to minimize impacts to the listed species (e.g., working quietly on-site, and minimizing time in or near habitats en route to their work sites).

• All project activities must comply with GRTE’s Superintendent’s Compendium related to food storage and park recommended best management practices for living and working in bear country.

Bear “attractants” include food, drinks, garbage, cooking utensils, dirty / soiled pots/pans/plates, stoves, grills (charcoal or gas), empty or full coolers, storage containers with food or previously holding food (except approved bear resistant canisters), beverage containers, pet food/bowls, and any odorous item that may attract a bear such as toiletries.

o At all times in all locations, including the backcountry, all staff (NPS, Volunteers-in-Parks (VIPs), contractors, etc.) must ensure that all bear attractants are attended at all times. All unattended attractants must be stored securely inside a building, a bear resistant food storage locker (if available), in a hard sided vehicle with doors locked and windows closed, or in an Interagency Grizzly Bear Committee (IGBC) approved portable bear resistant food storage canisters; or disposed of properly in a bear-resistant garbage receptacle. Backpacks and/or daypacks containing unsecured attractants (i.e. not in a canister) must not be left unattended.

o All personnel must attend a briefing on proper food/attractant storage and bear safety presented by a qualified member of the park's bear management team or their designee.

Please contact the park's Bear Management Office (307-739-3673) at least two weeks prior to the desired start date to schedule a briefing.

o All human-bear conflicts must be reported to Teton Interagency Dispatch Center immediately (307-739-3301). All bear sightings must be reported to the park’s Bear Management Office (307-739-3673) within 24 hours.

o Provide for proper storage and disposal of materials that may be toxic to bears. All potentially toxic attractants, including petroleum products, must be stored or disposed of in such a way that they are not available to bears.

o Construction debris must be separated from human food garbage and disposed of in dumpsters that can be closed at night. No open dumpsters are allowed. A request for an exception to the open dumpster stipulation, however, can be made to the project manager who will consult with the park’s Bear Management Office to determine if such use will be authorized. The use of open dumpsters will only be considered if the following conditions can be met: the open dumpster must be stored behind a locked fence out of view and inaccessible to the public, will be labeled construction debris only, and be inspected daily to ensure that no human food garbage is in the dumpster.

• For all projects occurring within the Grizzly Bear Primary Conservation Area (PCA), coordinate with the Bear Management Office (307-739-3673) to ensure that all project activities comply with habitat standards in the Final Conservation Strategy for the Grizzly Bear in the Greater Yellowstone Area (USFWS 2016, http://igbconline.org/yellowstone-subcommittee/), and to the extent practicable, that projects occurring in occupied grizzly bear habitat outside of the PCA adhere to the spirit of standards in the Final Conservation Strategy (USFWS 2016).

• Conservation recommendations (CR) provided in the USFWS 2016 biological opinion on the Historic Properties Management Plan to protect minimize or avoid effects to grizzly bear::

o CR1. Minimize human interaction and potential grizzly bear mortality by continuing the Park’s hazing strategies to prevent grizzly bears from becoming habituated to human residences.

o CR2. Grizzly bears concentrate in certain areas during specific time periods to take advantage of concentrated food sources or because the area provides a high seasonal food value due to diversity in vegetation and plant phenology (e.g., important spring or fall range). Where grizzly bear use is known or likely to occur and where practicable, delay disturbing activities during the spring in spring habitats to minimize displacement of grizzly bears.

o CR3 Manage building construction/removal and other activities in a manner that will minimize noise and visual disturbances and facilitate safe movement through habitat by grizzly bears.

o CR4. Control speed, traffic, and parking to minimize negative impacts to grizzly bear activity, including active enforcement of speed limits.

Attachment 1.10.A http://igbconline.org/yellowstone-subcommittee/ http://igbconline.org/yellowstone-subcommittee/

• All project activities will adhere to all relevant conservation measures outlined in the Lynx Conservation Assessment and Strategy (USFWS revised 2013). In particular, harvest of trees on site for the proposed activities within Lynx Analysis Units and/or in Critical Lynx Habitat will not be authorized without further review and analysis in consultation with USFWS.

• All project activities will comply with GRTE’s Superintendent’s Compendium closures implemented around wolf den/rendezvous sites. Should a den or rendezvous site not previously known be found within 1 mile of the proposed activity a seasonal area closure would be implemented as needed, typically between 15 April and 15 August.

• Prohibit construction activities before 8 a.m. and after 6 p.m. during the elk rutting and migration period (typically from September 1 to December 1, or as recommended by the park biologists).

• Avoid construction, maintenance, or other disturbing activities in crucial ungulate winter ranges (15 December to 15 April) and in identified ungulate parturition ranges (15 May - 30 June). See mitigation reference maps.

• Fencing (including temporary fencing for construction projects and permanent fencing) used in projects will comply with wildlife friendly fencing standards. Consult with the SRM Fish and Wildlife Branch Ungulate Biologist (307-739-3488) for assistance with specifications and appropriate design.

• For all herbicide applications, to the extent possible please conform to best management practices for wildlife. This includes following MSDS label instructions and avoiding sensitive times/areas for wildlife (e.g. bird nesting, fawning, den sites, bloom periods for pollinators).

• All wildlife-vehicle collisions must be reported to Teton Interagency Dispatch as soon as possible.

• A bat mitigation plan must be developed prior to initiating preservation, maintenance, or other activities in park structures that could negatively affect bats, their roosts, or hibernacula and/or if bat sign (bat vocalizations, smell of a bat roost, bat droppings on floors or walls, bat carcasses or skeletons, oily marks (from fur) around possible access points and roost areas, lack of cobwebs along beams, feeding remains such as moth wings or other insect parts, or other sign) is observed at any site. Buildings with any of the following characteristics (largely undisturbed; large roof void; large dimension roof timbers with cracks, joints and holes; uneven roof covering with gaps; ; hanging tiles or wood cladding; setting close to woodland and/or water; early 20th century or older construction; or roof warmed by the sun) may have a high probability of being used by bats.

- It is the responsibility of the park project lead to notify park biologists proposed work activities, and to schedule surveys with enough lead time to minimize project implementation delays. If roosting bats are found in buildings, work on those structures will be delayed until after the roosting period. Qualified personnel must perform a survey within the appropriate timeframe (i.e., spring surveys for maternity roosts, summer surveys for summer roosts, winter surveys for hibernacula) prior to initiating work and, if bats are found, develop a mitigation plan.

Wildlife – Amphibians

• Care will be taken not to disturb any wildlife species (amphibians, reptiles, migratory birds, mammals, raptors, or bats) found nesting, hibernating, estivating (in an inactive dormant state during hot, dry periods), or otherwise living in, or immediately nearby, worksites.

• Prior to work in or near wetlands or waterways the area will be assessed for its importance to amphibian species and prohibitions and limitations shall be set in order to protect these species.

Wildlife – Birds

• All project activities must comply with the Migratory Bird Treaty Act of 1918 (MBTA; 16 U.S.C.

703) and Executive Oder 13186. Under the MBTA, it is illegal to "take" migratory birds, their eggs, feathers or nests. “Take” is defined (50 CFR 10.12) to include “pursuing, hunting, shooting, wounding, killing, trapping, capturing, or collecting.” The MBTA does not distinguish between “intentional” and “unintentional” take. Migratory birds include songbirds, waterfowl, shorebirds, and raptors. All project activities must also comply with GRTE’s Superintendent’s Compendium seasonal closure regulations for raptors, trumpeter swans, great blue herons, and other sensitive bird species.

o In general, park biologists recommend that to prevent impacts to nesting migratory birds and to avoid project delays, schedule work involving vegetation clearing, tree felling, fill placement, excavation, or other construction activities for outside of the nesting season. The breeding season is generally as follows for migratory songbirds (1 May to 1 August), or as dictated by nesting chronology.

o Before commencement of any activities that involve removal or manipulation of vegetation including large trees, grasses, and shrubs during the breeding season (see above) contact park biologists to schedule a survey for nesting birds. Surveys must be conducted by qualified personnel before tree removal and/or ground disturbing activities begin. To the extent possible, schedule surveys prior to 1 March the year of the proposed work.

o Inspect hazard trees for potential nest sites. Fell hazard trees that may contain nests outside the breeding season, if possible, unless there is an imminent threat to human health and safety.

o Work must be completed within two weeks of the nesting bird survey. If this is not possible, another survey must be scheduled with park biologists.

o Active bird nests located during surveys will be protected until nestlings fledge or the nest fails. Park biologists will monitor nests, determine mitigations, and provide updates to the project leader on nesting status.

o It is the responsibility of staff to report any nesting bird activity in the vicinity of proposed activity to park biologists in a timely way so that they may assess whether additional mitigation measures are needed to comply with the MBTA.

• Eagles are specifically protected under the Bald and Golden Eagle Protection Act of 1940 (16 U.S.C.

668-668c) and the MBTA. Project activities must not lead to the take of bald or golden eagles. The Bald and Golden Eagle Protection Act defines “take” to include disturbing birds.

o Implement seasonal closures (typically February 1 to August 15) of ½ mile (GYBEMP 1989, USFWS 2007) around occupied bald eagle nests and prohibit work on or occupancy of area within the closures while they are in effect.

o It is the responsibility of the staff to report any eagle activity in the vicinity of proposed activity to park biologists in a timely way so that they may assess whether additional mitigation measures are needed to comply with the BGEPA and MBTA.

• All project activities must comply with GRTE’s Superintendent’s Compendium closure regulations for sage-grouse leks and to the extent practicable all project activities occurring within occupied sage-grouse habitat within the core sage-grouse area will apply the management direction and conservation measures outlined in the Wyoming Governor's Executive Order 2015-4 and the Upper Snake River Basin Sage-Grouse Conservation Plan (2014).

o Continue to implement a seasonal closure (generally 15 March – 1 June) around the Moulton sage-grouse lek.

o Prohibit removal of shrub-steppe habitat within 4 miles of an occupied sage-grouse lek to protect breeding, nesting, and brood rearing habitat for sage-grouse in the park (generally between March 15 and June 30, or as recommended by park biologists monitoring sage-grouse). Exceptions may be made on a limited and case-by-case basis.

o Limit new permanent facilities (including, but not limited to roads, buildings, well pads, pipelines, leach fields, and vegetation treatments) within 0.6 miles of active sage-grouse lek areas.

o Restrict maintenance and rehabilitation activities between the hours of 6:00 p.m. and 8 a.m. at proposed activities within 4 miles of active leks/nesting complexes (generally from March 15

– June 30, or as recommended by park biologists).

o Limit noise to less than 10 decibels above ambient measures from 6:00 p.m. to 8:00 a.m. at the perimeter of leks (generally from March 1 – May 15, or as recommended by park biologists).

o Efforts will be made to minimize disturbance to mature sagebrush cover in identified winter concentration areas.

o Power or other utility lines should be buried when possible. If such lines cannot be buried, lines should be raptor proofed and located at least 0.6 miles from the perimeter of occupied sage-grouse leks. New transmission lines should be authorized or conducted only when it can be demonstrated that the activity will not cause declines in sage-grouse populations.

Construction of new transmission lines should occur July 1 and March 14. Power lines should be placed along or adjacent to existing long-term linear disturbance features whenever possible.

o Park biologists will use the Wyoming Density and Disturbance Calculation Tool (DDCT) to assess activities that involve vegetation or ground disturbance within the sage-grouse core area that correspond with recommended mitigations for sage-grouse and their habitat.
