Administrative Draft Environmental Impact Report Gill Medical Center Project efficient than at comparable construction sites in the region or the state. Construction contractors would purchase their own gasoline and diesel fuel from local suppliers and would conserve the use of their supplies to minimize costs and maximize profit.Additionally, construction equipment fleet turnover and increasingly stringent state and federal regulations on engine efficiency combined with state regulations limiting engine idling times and require recycling of construction debris, would further reduce the amount of transportation fuel demand during Project construction. For these reasons, it is expected that construction fuel consumption associated with the Project would not be any more inefficient, wasteful, or unnecessary than other similar development projects of this nature. As indicated in Table 4.8-4, the Project is estimated to consume 561,184 gallons of automotive fuel per year during operation, which would increase the annual countywide automotive fuel consumption by 0.144 percent. The amount of operational automotive fuel use was estimated using EMFAC 2017 computer program, which provides projections for typical daily fuel usage in San Joaquin County. This analysis conservatively assumes that all 3,975 anticipated automobile trips projected to be generated by the Project (KD Anderson and Associates 2020) would be novel to San Joaquin County.The Project would not result in any unusual characteristics that would result in excessive long-term operational automotive fuel consumption. Fuel consumption associated with vehicle trips generated by the Project would not be considered inefficient, wasteful, or unnecessary in comparison to other similar developments in the region. As indicated in Table 4.8-4, the Project is estimated to consume 13,548 gallons of aviation fuel per year, which would increase the annual countywide automotive fuel consumption by 0.003 percent.All helicopter fuel use would be utilized for emergency response and emergency preparedness, and as such the use of fuel by the Project for helicopter operation would not constitute an inefficient, wasteful, or unnecessary consumption of energy. Furthermore, several aircraft manufacturers are currently demonstrating technologies that reduce fuel burn. It is expected these technologies will become more prevalent in aircraft. Additionally, enhanced implementation of efficient aircraft operations can reduce fuel burn through operational improvements. For example, in 2014 the Federal Aviation Administration (FAA) completed the baseline ground infrastructure for Automatic Dependent Surveillance-Broadcast (ADS-B), the satellite-based successor to radar that provides increased situational awareness and airspace efficiency. A system known as En Route Automation Modernization (ERAM) can be used in place of the legacy HOST automation system that the FAA has used to control high-altitude airspace since the 1970s. ERAM increases air traffic flow and improves automated navigation and conflict detection services. Alternative fuels are also being produced, specifically bio-Jet Fuel, and could potentially be offered at the Project. Several government agencies have recently formalized the intent to support the goal of one billion gallons of bio-Jet Fuel production capacity and use for the Aviation Enterprise. For these reasons, this impact would be less than significant. Mitigation Measures No mitigation is required. Energy 4.8-9 October 2021
