10/28/2011 | PRODUCTION/RECLAMATION
• Remove well pad and road surface materials that are incompatible with post-production land use and re-vegetation
requirements
• Use only certified weed-free native seed in seed mixes, except for non-native plants that benefit wildlife
• Williams will use certified, weed free grass hay, straw, hay or other mulch materials used for the reseeding and
reclamation of disturbed areas.
• Install exclusionary devices to prevent bird and other wildlife access to equipment stacks, vents and openings.
• Reduce visits to well-sites through remote monitoring (i.e. SCADA) and the use of multi-function contractors.
• Avoid dust suppression activities within 300 feet of the ordinary high water mark of any reservoir, lake, wetland, or
natural perennial or seasonally flowing stream or river where possible.

10/28/2011 | PLANNING BMP's
• Share/consolidate corridors for pipeline ROWs to the maximum extent possible.
• Maximize the utility of surface facilities by developing multiple wells from a single pad (directional drilling), and by
co-locating multipurpose facilities (for example, well pads and compressors) to avoid unnecessary habitat fragmentation
and disturbance of additional geographic areas.
• Minimize newly planned activities and operations within 300 feet of the ordinary high water mark of any reservoir,
lake, wetland, or natural perennial or seasonally flowing stream or river.
• Avoid new surface disturbance and placing new facilities in key wildlife habitats in consultation with CDOW.
• Minimize the number, length, and footprint of oil and gas development roads
• Use existing roads where possible
• Combine and share roads to minimize habitat fragmentation
• Maximize the use of directional drilling to minimize habitat loss/fragmentation
• Maximize use of remote telemetry for well monitoring to minimize traffic
• Restrict oil and gas activities as practical during critical seasonal periods

• Install and maintain adequate measures to exclude all types of wildlife (e.g., big game, birds, and small rodents)
from all fluid pits (e.g., fencing, netting, and other appropriate exclusion measures).
