• Schedule necessary construction in stream courses to avoid critical spawning times.
• Surface roads to ensure that the anticipated volume of traffic and the weight and speed of vehicles using the road do not cause environmental damage, including generation of fugitive dust and contribution of sediment to downstream areas.
• Protect culvert inlets from erosion and sedimentation and install energy dissipation structures at outfalls
• Use the minimum right-of-way width and vegetation mats where pipelines cross riparian areas and streams wherever possible
• Construct fluid pit fences and nets that are capable of withstanding animal pressure and environmental conditions and that are appropriately sized for the wildlife encountered.
• Install impermeable barriers beneath fluid pits to protect groundwater, riparian areas and wetlands.
• Salvage topsoil from all road construction and other rights-of-way and re-apply during interim and final reclamation.
• Strip and segregate topsoil prior to construction. Appropriately configure topsoil piles and immediately seed to control erosion, prevent weed establishment and maintain soil microbial activity

| Interim Reclamation | Form: (02A )
400396266
5/1/2013 | Production/Reclamation
• Gate access roads where necessary to minimize/control access to “crucial habitats”
• Install automated emergency response systems (e.g., high tank alarms, emergency shut- down systems, etc.).
• Implement fugitive dust control program
• Avoid direct discharge of pipeline hydrostatic test water to any reservoir, lake, wetland, or natural perennial or seasonally flowing stream or river.
• Locate above-ground facilities to minimize the visual effect (e.g., low profile equipment, appropriate paint color, vegetation screening in wooded areas, etc.).
• Skim and eliminate oil from produced water ponds and fluid pits at a rate sufficient to prevent oiling of birds or other wildlife that could gain access to the pit.
• Apply an aggressive, integrated, noxious and invasive weed management plan. Utilize an adaptive management strategy that permits effective responses to monitored findings and reflects local site and geologic conditions
• Map the occurrence of existing weed infestations prior to development to effectively monitor and target areas that will likely become issues after development.
• Evaluate the utility of soil amendment application or consider importing topsoil to achieve effective reclamation.
• Use locally adapted seed whenever available and approved by landowner.
• Use appropriately diverse reclamation seed mixes that mirror an appropriate reference area for the site being reclaimed where approved by landowner.
• Conduct seeding in a manner that ensures that seedbed preparation and planting techniques are targeted toward the varied needs of grasses, forbs and shrubs (e.g., seed forbs and shrubs separately from grasses, broadcast big sagebrush but drill grasses, etc.)
• Emphasize bunchgrass over sod-forming grasses in seed mixes in order to provide more effective wildlife cover and to facilitate forb and shrub establishment.
• Seed during appropriate season to increase likelihood of reclamation success
• Do not include aggressive, non-native grasses in reclamation seed mixes
• Choose reference areas as goals for reclamation that have high wildlife value, with attributes such a diverse and productive understory of vegetation, productive and palatable shrubs, and a high prevalence of native species.
• Establish vegetation with total perennial non-invasive plant cover of at least eighty (80) percent of pre-disturbance or reference area levels.
• Establish vegetation with plant diversity of non-invasive species which is at least half that of pre-disturbance or reference area levels. Quantify diversity of vegetation using a metric that considers only species with at least 3 percent relative plant cover.
• Establish permanent and monumented photo points and vegetation measurement plots or transects; monitor at least annually until plant cover, composition, and diversity standards have been met.
• Observe and maintain a performance standard for reclamation success characterized by the establishment of a self-sustaining, vigorous, diverse, locally appropriate plant community on the site, with a density sufficient to control erosion and non-native plant invasion and diversity sufficient to allow for normal plant community development.
• Use early and effective reclamation techniques, including interim reclamation to accelerate return of disturbed areas for use by wildlife
• Remove all unnecessary infrastructure during the production phase.
• Reclaim reserve pits as quickly as practical after drilling and ensure that pit contents do not contaminate soil.
• Remediate hydrocarbon spills on disturbed areas prior to reclamation.
• Complete final reclamation activities so that seeding occurs during the first optimal season following plugging and abandonment of oil and gas wells.
• Perform interim reclamation to final reclamation species composition and establishment standards.
• Perform interim reclamation on all disturbed areas not needed for active support of production operations
• Remove and properly dispose of degraded silt fencing and erosion control materials after their utility has expired
• Remove and properly dispose of pit contents where contamination of surface water, groundwater, or soil by pit contents cannot be effectively prevented
• Apply certified weed free mulch and crimp or tacify to remain in place to reclaim areas for seed preservation and moisture retention
• Control weeds in areas surrounding reclamation areas in order to reduce weed competition
• Educate employees and contractors about weed issues
• Where possible, fence livestock and/or wildlife out of newly reclaimed areas until reclamation standards have been met and plants are capable of sustaining herbivory
• Conduct necessary reclamation and invasive plant monitoring.
• Census and assess the utilization of the reclaimed areas by the target species
• Maintain pre and post development site inspection records and monitor operations for compliance
• Utilize GIS technologies to assess the extent of disturbance and document the reclamation progression and the footprint of disturbances
• Identify native species for which commercial seed sources are not available. Provide support to contractors for developing cultivation and seed production techniques for needed species
• Conduct reclamation field trials to match seed mixes, soil preparation techniques, and planting methods to local conditions.

5/1/2013 | Drilling/Completions
• Continue application of BMPs to prevent wildlife from entering pits including fencing and netting where appropriate
• Limit days/hours operations where practical to minimize disturbance and traffic
• Promptly report spills that affect wildlife to the CDOW.
