Utilization of Muck Berms for Short-Term Perimeter Control

UTILIZATION OF MUCK BERMS FOR SHORT-TERM PERIMETER CONTROL

1. Preplan and determine project limits. Ensure space will allow berm.

2. Submit 1717 Site Management Plan and update SWPPP (amend plan to specific location(s)).

3. Submit 1717 weekly look-ahead schedule, with specific reference in how erosion prevention will be incorporated into the grading operation, or upgradient work area.

4. Where feasible (must document if infeasible in SWPPP), install first line of redundant perimeter at project limits, but within approved impact zone (ensure Push wetland soil and muck for form, and any equipment remains on correct zone of proposed impact). shape structural berm Rolled muck berm a. HI silt fence, b. hay bale barriers, c. SCLs, d. Silt Fence Barrier e. Flotation Containment Boom, or f. Combinations of above

5. Form muck berm. Goal to retain plant mass and soil a. Push muck to form vegetated ridge berm b. Roll muck to form vegetated ridge berm c. Place muck to form vegetated berm

6. Immediately stabilize all exposed muck with cover seed or wetland seed, and apply certified weed free mulch, blanket, hydromulch, plastic , or geotextile

7. Perform upgradient work and implement submitted weekly erosion prevention Pushed muck berm program Salvaged and placed muck berm 8.

Monitor stabilization results each week until 70 percent of perennial vegeta- tion has been restored over the surface.

Ideal spacing of redundant perimeter gap is 5 ft. Pushed and compact- ed muck berm Note stabilized muck berm against silt fence
