Landscaping/Post Construction Activities
A. Disturbed areas. All disturbed areas will be final graded to as close as
possible to its original condition.
B. Erosion. Erosion control structures such as water bars or "kicker dikes" will
be constructed. Water bars will be placed approximately every 25' on steep
slopes to prevent erosion over the right-of-way. Steep slope breaks will also
be made impassable to vehicular traffic by using deep waterbars, leaving them
rough.
C. Weed Control. EnCana shall be responsible for weed control on disturbed
areas within the limits of the right-of-way. EnCana will be responsible for
consultation with the authorized officer and/or local authorities for acceptable
weed control methods (within limits imposed in the grant stipulation).
D. Drainages. The banks of drainage crossings will be returned and stabilized to
their original slope to avoid ramping and opening them to livestock and
vehicle traffic.
E. Visuals. Where applicable, the upper rim rock will be replaced to discourage
traffic and mitigate visual scarring.
F. Painting. All aboveground facilities will be painted with the Carlsbad Canyon
2.5 Y 6/2 color or similar color to blend in with the surrounding area.
G. Seeding. EnCana will seed all disturbed areas along the pipeline corridor with
the recommended seed mixtures as provided by the BLM, and summarized in
the following table:

1 Drill seeding rate = lbs/acre pure live seed (PLS).
2 Substitution for shadscale saltbush: Gardner's saltbush.
3 Substitution for globemallow: western yarrow or blue flax.
Seed shall be planted using a drill equipped with a depth regulator to ensure proper depth
of planting where drilling is possible. The seed mixture shall be evenly and uniformly
planted over the disturbed area. Where drilling is not possible, seed shall be broadcast
and the area shall be raked or chained to cover the seed. When broadcasting the seed, the
pounds per acre will be doubled. Steep slopes will not be drill seeded so to avoid
establishing rills. The seeding will be repeated until a satisfactory stand is established as
determined by the authorized officer. Evaluation of growth will not be made before
completion of the first growing season after seeding. The authorized officer will be
notified a minimum of 5 days prior to the seeding of the project.
Seeding will occur during spring or late fall seasons when ground frost is not present.
Reclamation
The expected life of the EnCana River Water Pipeline is 30 years. Reclamation will
consist of the following:
Removal of all surface equipment and appurtenances.
- Restoration and re -contouring of grade to approximate original conditions.
- Replacement of stockpiled topsoil.
Compliance with all prevailing Colorado Oil and Gas Conservation
Commission and Garfield County regulations governing final reclamation.
- Prior to termination of the right-of-way, EnCana shall contact the authorized
Federal officer to arrange a pre -termination conference. This conference will
be held to review the termination provision of the grant.
