Responsible <br /> Significant <br /> Measures and Statements of Findings of Impacts Being pMonitoring/ Party for Providing Monitoring/Reporting Timing <br /> Slgnlficant and Unavoidable Reporting Action Mitigation Responsibility <br /> AIR-3: Implement Mitigation Measures AIR-2a,AIR-2b,AIR-2c,AIR-2d,and Verification by County. Union Pacific Union Pacific with During project operations <br /> AIR-2e.Mitigation measures potentially applicable to the project were reviewed verification provided to San <br /> under Impact AIR-2.Because the candidate mitigation measures reduce both Joaquin County Community <br /> criteria pollutant emissions as well as emissions of air toxics(DPM),the same Development Department <br /> measures that were feasible to Implement under Impact AIR-2 are also <br /> considered mitigation measures for Impact AIR-3. <br /> Less than significant impact after implementation of Mitigation Measures <br /> AIR-2a through AIR-2e. <br /> 4.3 Air Quality and Greenhouse Gases(cont.) <br /> AIR-4:Implement Mitigation Measures AIR-2a,AIR-2b,AIR-2c,AIR-2d,and Verification by County. Union Pacific Union Pacific with During project operations <br /> AIR-2e.Mitigation measures potentially applicable to the project were reviewed verification provided to San <br /> under Impact AIR-2.Because the candidate mitigation measures would reduce Joaquin County Community <br /> both criteria pollutant emissions as well as emissions of air toxics(DPM),the Development Department <br /> same measures that were feasible to Implement under Impact AIR-2 are also <br /> considered mitigation measures for Impact AIR-4. <br /> Less than significant Impact after Implementation of Mitigation Measures <br /> AIR-2a through AIR-2e. <br /> 4.4 Noise <br /> NOISE-1a:Reduce truck rebound Impact noise by removing speed bumps and Verification by County. Union Pacific Union Pacific with During project operations <br /> by posting large,clearly visible signs requiring drivers to observe maximum verification provided to San <br /> allowable speeds.In addition,Install radar-operated or induction-loop operated Joaquin County Community <br /> large electronic speed Indicator signs with rapidly flashing alerts in case of Development Department <br /> speed violations to clearly signal drivers their current speed. <br /> In addition,maintain the roads so asKo reduce truck vibration due to surface <br /> roughness,expansion joint gaps,cracks and holes that would otherwise <br /> generate impact noise. <br /> NOISE-1b:Reduce container landing Impact noise by requiring crane operators <br /> to utilize software/sensor controls to tightly control descent speeds in the last few <br /> seconds before impact. <br /> NOISE-1c:The applicant shall test the feasibility of utilizing electric hybrid <br /> cranes as an alternative to diesel powered gantry cranes and shall Incorporate <br /> such hybrid cranes Into the project's operations if the applicant determines they <br /> are operationally and economically feasible. <br /> NOISE-1d:The applicant shall replace the current single-tone backup alarms <br /> used in Gantry Cranes and other vehicles with Ambient-Sensitive Self-Adjusting <br /> Backup Alarms,which automatically Increase or decrease their volume based <br /> upon background noise levels to ensure that the tone produced is no louder than <br /> necessary.Applicant should also test the safety implications of replacing single- <br /> tone backup alarms with less intrusive broadband noise types and determine if <br /> such replacement is feasible without compromising yard safety <br /> Less than significant impact after implementation of Mitigation Measures <br />
