Environmental Consequences projects (listed above in Section 4.5) using conservative assumptions to create worst case scenarios. Site preparation (i.e., earth moving and soil disturbance) and wind erosion for the projects would result in various amounts of fugitive particulate (i.e., dust) emissions (PM10 and PM2.5). The amount of fugitive dust emissions would depend on numerous factors, such as: the degree of vehicular traffic; amount of exposed soil; soil moisture content; and wind speed. Construction activities would create combustion product (tailpipe) emissions (mostly PM, NOX, and CO) from vehicles (e.g., contractor personally owned vehicles, delivery trucks, heavy construction equipment), and temporary non-road equipment powered by internal combustion engines. BMPs (e.g., dust suppression, establishment of lower speed limits in construction areas) and legal requirements (i.e., use of low sulfur fuel, anti-idling regulations) would be implemented during each project to minimize and mitigate those emissions to the maximum extent practicable. Criteria pollutant emissions from mobile sources associated with the WFF projects listed in Table 29 would be short-term, negligible, and localized. The operational phases of these projects would produce similar criteria pollutant emissions on an annual basis, although only the first year of operational emissions was estimated. BMPs (e.g., use of alternative fueled vehicles at WFF) and installation of the two wind turbines proposed for the Alternative Energy Project would help minimize criteria pollutant emissions locally. In addition, a positive impact in a regional reduction in criteria pollutant emissions could result from the decreased use of fossil fuels during the production of electricity at the electric power generation plant that currently supplies WFF.

Environmental Consequences Although cumulative impacts from all construction related and operational activities are anticipated to be minimal, WFF is in the process of decentralizing the Central Boiler Plant/steam system with individual propane-fired boilers. Table 30 provides the estimated emissions reduction resulting from this action.
