<br />Sequoia Ecological Consulting, Inc. <br />CalVTP Project-Specific Analysis and Addendum <br />Augustin Bernal Community Park Fuel Reduction <br />November 2025 <br />A-57 <br /> <br /> <br />MITIGATION MEASURES APPLICABLE? <br />(Y/N) TIMING IMPLEMENTING <br />ENTITY <br />VERIFYING/ <br />MONITORING <br />ENTITY <br />Where feasible, project proponents would implement emission reduction techniques to <br />reduce exhaust emissions from off-road equipment. It is acknowledged that due to cost, <br />availability, and the limits of current technology, there may be circumstances where <br />implementation of certain emission reduction techniques would not feasible. The project <br />proponent would document the emission reduction techniques that would be applied and <br />would explain the reasons other techniques that could reduce emissions are infeasible. <br />Techniques for reducing emissions may include but are not limited to the following: <br />• Diesel-powered off-road equipment used in construction would meet EPA’s Tier 4 <br />emission standards, as defined in 40 CFR 1039, and comply with the exhaust <br />emission test procedures and provisions of 40 CFR Parts 1065 and 1068 <br />o Tier 3 models can be used if a Tier 4 version of the equipment type is <br />not yet produced by manufacturers <br />o This measure can also be achieved by using battery-electric off-road <br />equipment as it becomes available <br />o Prior to implementation of treatment activities, the project proponent <br />would demonstrate the ability to supply the compliant equipment <br />o A copy of each unit’s certified tier specification or model year <br />specification and operating permit (if applicable) would be available <br />upon request at the time of mobilization of each unit of equipment <br />• Use renewable diesel fuel in diesel-powered construction equipment <br />o Renewable diesel fuel must meet the following criteria: <br />▪ Meet California’s Low Carbon Fuel Standards and be certified <br />by CARB Executive Officer <br />▪ Be hydrogenation-derived (reaction with hydrogen at high <br />temperatures) from 100 percent biomass material (i.e., non- <br />petroleum sources), such as animal fats and vegetables <br />▪ Contain no fatty acids or functionalized fatty acid esters <br />▪ Have a chemical structure that is identical to petroleum-based <br />diesel and complies with American Society for Testing and <br />Materials D975 requirements for diesel fuels to ensure <br />compatibility with all existing diesel engines
