AECIIV Climate Change/Greenhouse Gas Emissions. A project. If components are added to the project that are quantification ofoperational-period greenhouse gas not related to the grade separation then the statutory (GHG) emissions associated with implementation of the exemption may not apply and additional work not proposed project will be conducted. Consistent with covered in this scope and cost, including a CEQA current Caltrans policy, construction-period GHG document, may be required. emissions will not be quantified. Operations-period GHG emissions will be quantified using regional daily peak-period and non-peak-period vehicle miles traveled (VMT) apportioned into 5 mph speed bins for speeds A Notice of Exemption (NOE) will be prepared and between 5 mph and 75 mph; and the CT-EMFAC provided to the City for approval and submittal to the emissions model. ICF Jones & Stokes will present a State Clearinghouse. This notice starts the statue of comparison of GHG emissions associated with the Build limitations under CEQA so it is recommended that the Alternative(s) to the No-build Alternative to characterize City file this notice. No additional CEQA documentation effects of the proposed project on GHG emissions. The beyond the completion of the NOE form is assumed as analysis of climate change also will also incorporate the part of this scope and cost. most recent guidance found on the Caltrans Standard Based on the environmental technical studies Environmental Reference and Caltrans annotated previously discussed a Categorical Exclusion (CE) will be outline. prepared pursuant to NEPA.

Railroad grade separations are Deliverables (S Copies Each).• identified as NEPA Categorical Exclusions under 23 CFR Notice ofExemption 771.117(4). Railroad grade separations are statutorily Draftand Final Categorical Exclusion and exempt from CEQA, as identified in Section 21080.13 of MMRP the Public Resources Code and in Section 15282(8) of the CEQA Guidelines. Statutorily exempt projects are excused entirely from the environmental review process and the requirements of CEQA. In addition, all activities performed to support these projects are also included in If for some reason a NEPA CE were found to be not the exemption. It is assumed that all project appropriate for the proposed project then an components are associated with the railroad grade Environmental Assessment/Finding of No Significant separation and would be covered under the exemption.
