AECOM Climate Change /Greenhouse Gas Emissions. A quantification of operational - period greenhouse gas (GHG) emissions associated with implementation of the proposed project will be conducted. Consistent with current Caltrans policy, construction - period GHG 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 between 5 mph and 75 mph; and the CT -EMFAC emissions model. ICF Jones & Stokes will present a comparison of GHG emissions associated with the Build Alternative(s) to the No -build Alternative to characterize effects of the proposed project on GHG emissions. The analysis of climate change also will also incorporate the most recent guidance found on the Caltrans Standard Environmental Reference and Caltrans annotated outline. Air Quality ConformityAnalysis Report and Checklist. Under NEPA delegation, the federal air quality conformity determination has not been delegated to Caltrans and must be made by FHWA. We will prepare a separate Air Quality Conformity Analysis using the annotated outline for this report on the SER at the time that the report is initiated and will also prepare the Conformity Checklist based on the checklist that is available on the SER at the time that the Air Quality Conformity Analysis Report is prepared. SCA G Transporta tion Conformity Working Group. T h e required TCWG form will be completed and submitted for forwarding to SCAG for inclusion on the agenda for determining if the project is a project of air quality concern ( POAQC). It is assumed the project will be found to not be a POAQC and that no specific analysis will be required related to the TCWG determination other than what is already included in this scope of work. Mitigation Measures. ICF Jones & Stokes will develop mitigation measures, where applicable, to address significant air quality impacts, if present. For the proposed project it is assumed that the NEPA document to be prepared will be a Categorical Exclusion with technical studies. Railroad grade separations are identified as NEPA Categorical Exclusions under 23 CFR 771.117(d). Railroad grade separations are statutorily exempt from CEQA, as identified in Section 21080.13 of the Public Resources Code and in Section 15282(g) 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 the exemption. It is assumed that all project components are associated with the railroad grade separation and would be covered under the exemption. Therefore, it is assumed that no CEQA document or documentation will be required for the proposed project. If components are added to the project that are not related to the grade separation then the statutory exemption may not apply and additional work not covered in this scope and cost, including a CEQA document, may be required. C` + C A * "categorical Exclusion A Notice of Exemption (NOE) will be prepared and provided to the City for approval and submittal to the State Clearinghouse. This notice starts the statue of limitations under CEQA so it is recommended that the City file this notice. No additional CEQA documentation beyond the completion of the NOE form is assumed as part of this scope and cost. Based on the environmental technical studies previously discussed a Categorical Exclusion (CE) will be prepared pursuant to NEPA. ICF Jones & Stokes will prepare the CE in compliance with the latest format identified on Caltrans Standard Environmental Reference website. In addition, the Categorical Exclusion Checklist will be prepared. As part of the CE a detailed project description will be included. The CE will also include a very brief (two to three sentence) summary of the findings of each of the technical studies. No separate environmental document is assumed to be prepared to support the CE and none is included in this scope and cost. It is assumed that ICF Jones & Stokes will revise the CE twice based on comments from the City and Caltrans (to be reviewed concurrently). Environmental Commitments Record For the project an environmental commitments record (ECR) will be prepared in a matrix table format. The ECR will be submitted to the City and Caltrans in hard copy and electronic form. The matrix table will include a description of each mitigation measure organized by topic numbered to correspond with the impacts. For each mitigation measure, the Reporting Process, Timing of Measure, Responsible Party, and Verification of Compliance will be identified through coordination with resource agencies and experience on other similar projects. The ECR will be included with the CE and it is assumed that this document will be reviewed as part of the City and Caltrans review of the CE. Deliverables (5 Copies Each) • Notice of Exemption • Draft and Final Categorical Exclusion and MMRP Optional Scope for Environment-' Assessment /Finding of No Signiilk aWIL impact, if If for some reason a NEPA CE were found to be not appropriate for the proposed project then an Environmental Assessment /Finding of No Significant Impact (EA /FONSI) would be prepared. Under this scenario the previously identified Section 4.0 (Environmental Document) scope would be replaced Proposal for Project Study Report Equivalent and Conceptual Engineering Plans for Santa Ana Boulevard Grade Separation Project
