All motor vehicles will be maintained to reduce the potential for vehicle-related noise.To minimize disturbances from helicopter use, USBP will review landing and takeoff routes todetermine what actions could be taken, such as alternating or rotating routes, and timing the useof different routes to reduce noise effects on wildlife or residents in the San Bernardino Valley.All helicopters will be maintained and operated to reduce the potential for engine-related noise.Solid and Hazardous Wastes:Care will be taken to avoid impacting the project area with hazardous substances (e.g., antifreeze,fuels, oils, lubricants) used during construction. Although catch pans will be used whenrefueling, accidental spills could occur as a result of maintenance procedures to constructionequipment. However, the amount of fuel, lubricants, and oil is limited, and equipment necessaryto quickly contain any spills will be present when refueling.Transportation:Modular buildings and other equipment will be transported on appropriate roads with properflagging and safety precautions.Findings and Conclusions: No significant adverse impacts are anticipated for any resourceanalyzed within this document. Therefore, no further analysis or documentation (i.e.,Environmental Impact Statement) is warranted. CBP, in implementing this decision, wouldemploy all practical means to minimize the potential adverse impacts on the human andbiological environment.Project Proponent: _______________________________ ______________Efren V.
