' the project area. Parts of the equipment that have come in contact with the soil will be washed or otherwise cleaned of all soil and visible seed. Reclamation equipment will ' also be washed or otherwise cleaned of all soil and visible seed after having been used in areas with identified noxious weeds. 2.1 Backfilling and Regrading Backfilling will be completed using the spoil previously excavated from the trench. The backfill procedure will include removing all obvious earthwork by removing embankments, backfilling excavations, and grading to re-establish the approximate original contours of the land in the ROW. ' Where settling may be a problem, backfill will be mounded over the trench approximately 0.5 foot to compensate for subsidence unless otherwise specified by the BLM or other landowner. The ROW and temporary use areas will not be lower than the natural grade. Final grading and installation of erosion control measures will be completed after the ' trench is backfilled. Proper compaction and recontouring will be completed prior to replacing topsoil. ' All hillsides, stream banks and beds, non-essential access roads, and other areas where earth has been moved will be restored as close possible to the original contours of the land. This includes moving all fill material back into any sidehill cuts that were ' necessary to construct the pipeline. 2.2 Topsoil Replacement ' Once the sites have been recontoured and compacted, topsoil will be redistributed over the entire disturbed area from which it was salvaged. Depths of redistributed topsoil will vary depending upon available stripping depths. Topsoil will not be mixed with spoil material before or during replacement, and only ' topsoil will be respread. Topsoil from unstripped areas will not be used to cover adjacent disturbances. Topsoil will not be handled during excessively wet conditions or at times when the ground or topsoil is frozen. The length of time topsoil is stockpiled ' will be minimized. Normally, topsoil redistribution will occur within one week of topsoil stripping. ' Replaced topsoil will be left in a roughened condition to minimize erosion. Additional erosion control and soil stabilization measures may be required on steeper slopes, in areas of erodible soils, and in areas adjacent to or within drainages. 2.3 Seedbed Preparation ' The topsoil seedbed will be roughened by harrowing, tilling, or other methods to create microhabitats that enhance revegetation. By creating surface roughness, the likelihood of seed establishment will be increased due to increased infiltration and improved soil moisture availability and retention.
