A. Location - Unless otherwise designated, firelines shall be located adjacent to the unit boundary, within 50 feet outside of actual unit boundary, in locations affording the optimal holding capability, and remain on agency property. The Government may choose to clearly mark the preburn and post-burn fireline location with colored plastic ribbon. The fireline shall be constructed to follow the flagged line as closely as possible. Variations will be permitted if unforeseen obstacles are found. Specialty species (i.e., Pacific Yew or other specialty species in a task order) shall not be cut or damaged. Fireline location shall avoid the necessity of cutting or limbing these specialty species. The COR shall be notified if cutting or limbing of these species is unavoidable prior to cutting.

B. Clearing Limits – Mechanical fireline shall be cleared to a width of 8 feet and a height of 8 feet. The width shall be measured parallel with the ground (slope distance). The height shall be measured from the side of the line away from the unit. A strip at least 1.5 foot wide to a maximum of 3 feet wide, and centered within the cleared area shall be cleared to mineral soil. A strip less than 1.5 foot wide may be designated by the COR on some units.

C. Material to be cleared - Within the 8-foot line, the following material shall be cut and removed:

1. Shrubs, brush and other vegetation. Cut to within 18 inches of ground level or as close as possible without damaging tools.

2. Cut live and dead trees at ground level or as close as possible without damaging tools. No trees larger than 7 inches DBH shall be cut. The fireline shall be located to avoid larger green trees.

3. Limbs extending within the fireline shall be cut close to the tree if the point of cutting can be reached from the ground (about 8 feet from the ground). Limbs shall be cut when they enter the fireline clearing limits if they cannot be cut at the tree. Limbs cut close to the tree need not be cut flush but "spike" limbs will not be allowed.

4. Slash and litter shall be removed from the 8-foot (both height and width) fireline clearing strip. Natural ground duff need not be removed except from within the 3-foot strip on the fireline work area.

5. A 3-foot section shall be removed from logs located across the fireline.

D. Disposal of Cleared Material - Material cut from within the fireline shall be placed on the unit side (inside) of the fireline and scattered. Soil berms and piles will not be permitted on top of flammable material. Log sections may be rolled downhill and away from the unit provided that they are left outside the fireline.

E. Snags and High Stumps - Snags or high stumps may be left next to the fireline when designated or approved by the Government.

F. Side Slopes - On side slopes that are steeper than 30 percent, the 3-foot wide strip shall be cup trenched sufficiently to catch rolling material 6 inches or less in diameter.

G. Water Bars - Water bars shall be constructed in all firelines at the time of initial construction. The water bar shall consist of a diagonal ditch across the three-foot wide mineral soil portion of the fireline, but not in excess of the following guidelines. The water bar shall be approximately 6 inches to 10 inches deep and approximately 5 feet long. Unless otherwise directed, drainage shall allow rolling material and drainage into burn unit.

Percent of Slopes: 00% - 09% - None Required

10% - 29% - 1 Water Bar Every 300' 30% - 59% - 1 Water Bar Every 150' 60% + - 1 Water Bar Every 100'
