b. Ford Ranch Playa Outfall T58N R75W Sec. 27 SWNE Playa Outfall Description- Outfall consists of a black poly apron and partially buried black poly corrugated pipe (14” diameter by 100 feet). Large black poly corrugated riser (48” diameter) and a valve set within a 12” smooth poly riser. Riser caps and (2) wooden posts. Access Road to the Playa outfall may require spot upgrades due to erosion in several spots. See Figure 6 Photos.

-Removal and Reclamation Procedure:

A. Contractor shall remove all infrastructure associated with the outfall and recontour to the surrounding topography then re-seed the disturbed areas with BLM seed mix specified in the attached reclamation plan.

B. Removal of pipe: Excavate approximately 3 to 5 feet deep, cut pipe from valve or riser (typically up to 2 inch or 3-inch diameter and black HDPE), fuse cap to existing pipe, remove and dispose of valve, backfill with existing material, and compact in one-foot lifts. Valve sets may be up to 8-inch diameter.

C. Electrical panels – Contractor shall be responsible for locates, verifying conductors are “dead”, excavating approximately 3-feet deep, cutting the wires, backfilling with existing materials, compacting in one-foot lifts.

D. Strip 6 inches of topsoil from a 10-foot radius around the disturbance and store in a pile adjacent to the work site for final reclamation. Excavate around any removed infrastructure to a depth adequate to cut and cap any piping a minimum of 3 feet below ground surface.

Access Road: May require spot upgrade to perform the work. Will not be reclaimed.

FIGURE 2: Reclamation for Skewed well area

Site Description The Skewed Reservoir Reclamation area is located in Johnson County, Wyoming, NWSE Section 21, T48N/R77W; UTMs 410491E/4885436N. It falls within the 10-14-inch Northern Precipitation Zone and a Loamy-Shallow Loamy Ecological Site Description (ESD). The site lies on a south aspect with a slopes ranging from 3-15%.

See photos in Appendix 1 and maps in Appendix 2.

Reseeding Plan Requirements:

-Rip and reseed the reclaimed reservoir location; an area of approximately 7.7 acres.

- Waterbars are to be constructed a minimum of 18 inches deep, on the contour with no more than 2 feet of drop per 100 feet of waterbar to ensure drainage and extended into established vegetation. All waterbars are to be constructed with the berm on the downhill side to prevent the soft material from silting in the trench. The initial waterbar will be constructed at the top of the backslope. See Figures 3 and 4.

-The soil is to be ripped and prepped for seed bed, mulched, and seeded with the seed mix listed below. Mulch and seed are to be from a weed free certified source.

-Drill seed at a depth not to exceed 0.5 inches. If broadcast seeding, double the rate of application.

-Apply mulch at a minimum rate of 1000 pounds per acre. Mulch maybe wood chips or straw.

-Apply seed at the specified rate. See FIGURE 1 BLM approved seed mix.
