AUGUSTIN BERNAL MOUNTAIN BIKE TRAIL PROJECT DRAFT INITIAL STUDY Less Than Significant Potentially Impact With Less Than Significant Mitigation Significant Impact Incorporated Impact No Impact e) For a project located within an airport land use plan or,where such a plan has not been adopted,within two miles of a public airport or public use airport, ❑ ❑ ❑ would the project result in a safety hazard or excessive noise for people residing or working in the project area? f) Impair implementation of or physically interfere with an adopted emergency El ❑ ❑ response plan or emergency evacuation plan? g) Expose people or structures,either directly or indirectly,to a significant risk ❑ of loss, injury or death involving wildland fires? Setting Hazardous materials stored and used in the area surrounding the project area would likely be associated with common materials used in commercial and recreational activities, such as paints, cleaning solvents, bonding agents, and small quantity petroleum fuels and lubricants, as well as herbicides and pesticides used for common weed and pest control applications. A search of the State Geotracker and Envirostor databases determined that no active hazardous materials cleanup sites are located in proximity of the project site. Livermore Pleasanton Fire Department provides emergency response to the project site. Impact Discussion a) Would the project create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials? Construction of the project would involve the use of common hazardous materials used in construction, including petroleum-based fuels, hydraulic fluids,and lubricants used in vehicles and equipment. Large quantities of these materials would not be stored at or transported to the construction site. All construction waste materials would be disposed of in compliance with state and federal hazardous waste requirements and at appropriate facilities.Construction would comply with the requirements for storage,spill prevention and response and reporting procedures,and by implementing erosion control and pollution prevention measures included in the trail design plans (see Section 3.7, Geology and Soils, including MM-GEO-1; Section 3.10, Hydrology and Water Quality; and Appendix A). Additionally, MM-HAZ-1 requires specific measures for spill prevention and containment of hazardous materials on the project site during construction. 12956 DUDEK 61 April 2022
