Biomass Disposal <br />The goal of biomass disposal is to reduce ignitable material and associated air quality impacts from <br />wildfire, reduce brood material for harmful insects and disease, and enhance aesthetics. By reducing the <br />available fuel in the shaded fuel break, the fuel continuity is disrupted, which slows down the spread of <br />wildfires and decreases potential fire intensity. <br />Methods for managing biomass include natural decomposition (e.g., chip and broadcast, lop and scatter), <br />hauling off-site, and pile burning. To mitigate brood stratum opportunities for beetles, downed logs would <br />not be left on site, in accordance with California Forest Practice Rules (CAL FIRE 2019) and BMPs. <br />Whenever feasible, natural decomposition of biomass would be preferred because: (1) forestry mulch aids <br />in mitigating erosion and excessive soil disturbance; (2) keeping material on-site prevents the spread of <br />disease and pathogens to other sites, with Sudden Oak Death (SOD; Phytophthora ramorum) being of <br />particular concern in our region; and (3) GHG emissions are reduced by avoiding the transportation of <br />material off-site to green waste facilities. For all these reasons, the most climate-friendly option is to leave <br />woody biomass on-site to decompose naturally. <br />2.2.6.1. Natural Decomposition <br />Cut vegetation may be retained on-site to decompose naturally via lopping and scattering or chipping and <br />broadcasting across the landscape. Lopping plants involves cutting a plant low to the ground and <br />distributing the cut material. In some cases, a road-based chipper or an all-terrain vehicle and tracked <br />towable chipper would be used to process cut vegetative materials. The vegetative material would be fed <br />through the chipper and broadcast widely into treatment areas. Biomass would be chipped to 3 inches or <br />smaller in size and spread up to 4 inches deep. Cut vegetation and chips would not be placed below the <br />ordinary high water mark of aquatic features, within wetlands or riparian areas, or on top of burrows or <br />rock piles. Understory debris chipped and scattered on-site would follow BMPs for reducing the spread of <br />pests, disease, noxious weeds, and invasive species (see Section 2.5). <br />2.2.6.2. Hauling Off-Site <br />Vegetation moved off-site would be hauled to an appropriate biomass-processing facility. Transported <br />invasive plant materials would be stored in a closed container to prevent spreading during transport. <br />2.2.6.3. Pile Burning <br />Hand-cut material would be piled as “feeder piles,” with the cut stems facing in one direction in a manner <br />to minimize any overstory scorch when the piles are restacked and burned. Most of the piles would be <br />built in open areas of the forest floor or on the roadside. Suitable areas for pile burning are open areas
