During construction activities there may be minor, temporary visual effects including silt fencing, staged construction materials, and heavy equipment at the project site. These activities, would be short term, temporary and limited to the duration of the construction. Following construction, aesthetics would improve. Construction equipment will be removed and all construction materials will be utilized or disposed. Exposed soil would be graded accordingly and revegetated to prevent erosion. Silt fences will be removed upon adequate revegetation and stabilization of upslope areas. The project site is generally screened from Highway 169 and adjacent properties by existing mature trees and rolling topography. The project design is to preserve as much of this screening as possible along the property perimeter to limiting views of the off-road truck track from neighboring properties. 16. Air: a. Stationary source emissions - Describe the type, sources, quantities and compositions of any emissions from stationary sources such as boilers or exhaust stacks. Include any hazardous air pollutants, criteria pollutants, and any greenhouse gases. Discuss effects to air quality including any sensitive receptors, human health or applicable regulatory criteria. Include a discussion of any methods used assess the project's effect on air quality and the results of that assessment. Identify pollution control equipment and other measures that will be taken to avoid, minimize, or mitigate adverse effects from stationary source emissions. Not applicable. There are no stationary source emissions. b. Vehicle emissions - Describe the effect of the project's traffic generation on air emissions. Discuss the project's vehicle -related emissions effect on air quality. Identify measures (e.g. traffic operational improvements, diesel idling minimization plan) that will be taken to minimize or mitigate vehicle -related emissions. Vehicle related air emissions include carbon monoxide, hydrocarbons, NO., particulate matter and sulfur dioxide from automobiles, trucks and construction equipment. During the construction period, emissions from internal combustion engines will occur from heavy construction equipment. To reduce the emission of pollutants, engines will be properly maintained and measures will be implemented to limit emissions by decreasing idle times on vehicles and equipment. Emissions from passenger vehicles will be increased in the area by attendees traveling to the facility for the bi-annual events. Vehicle idling will be minimized by implementing event specific parking and circulation plans to ensure prompt, efficient and safe spectator parking. Emissions from off-road trucks competing in the races will be minimal, infrequent and short- term. Campfires will be required to comply with all applicable state and local requirements. Campfires will be limited to no more than three feet in height and three feet in diameter. Material burned will be limited to clean, dry wood. Oils, rubber, plastics, chemically treated materials, painted wood, or garbage will be prohibited from burning. c. Dust and odors - Describe sources, characteristics, duration, quantities, and intensity of dust and odors generated during project construction and operation. (Fugitive dust may be discussed under item 16a). Discuss the effect of dust and odors in the vicinity of the project Page 20
