SUNOL BOULEVARD/I-680 IMPROVEMENTS PA&ED jurisdictional waters, and the results summarized in an abbreviated Natural Environment Study(NES) or NES-Minimal Impact(MI)that incorporates the NES for EA 04-0Q3000 by reference. Depending on the extent of project activities, either a Letter of Concurrence request(informal consultation)or a Biological Assessment(formal consultation)will be needed for Section 7 consultation with the U.S. Fish and Wildlife Service(USFWS). For purposes of this scope, it is conservatively assumed that a Biological Assessment will be prepared.No creeks are in the anticipated project footprint and no in-water work is proposed; therefore,neither consultation with the National Marine Fisheries Service nor a fish passage assessment will be necessary. An abbreviated Wetland Delineation Report that incorporates the NES for EA 04- 0Q3000 by reference will be prepared to document potentially jurisdictional waters in the project area. Subtask 4.8 Air Quality,Greenhouse Gas,& MSAT Report. This project is included in the Metropolitan Transportation Commission's(MTC's) current Regional Transportation Plan and Sustainable Communities Strategy(RTP/SCS),Plan Bay Area 2040 (RTP ID 17-01-0044). The project is not currently included in MTC's financially constrained 2017 Transportation Improvement Program(TIP), and the CITY will need to amend it into the TIP prior to the end of PA&ED. Project-level conformity to the State Implementation Plan will have to be demonstrated as part of project approval. Therefore,CONSULTANT will prepare an Air Quality Impact Assessment to identify sensitive receptors(primarily single-family residences in the southeast interchange quadrant) and provide a quantitative analyses of construction- related emissions, mobile source air toxics, and operational and construction greenhouse gas emissions for Build Alternatives 1 and 2. Findings will be detailed in a single Air Quality Impact Analysis report. Transportation conformity requirements no longer apply for the National Ambient Air Quality Standard for carbon monoxide; therefore, a carbon monoxide hot spot analysis is not needed and will not be included. CONSULTANT will consult with the Bay Area Air Quality Conformity Task Force on the CITY's behalf regarding whether the project is a Project of Air Quality Concern for particulate matter of 2.5 microns or less(PM2.5). The project would allow for a nominal increase in capacity; therefore, completion of MTC's PM2.5 Assessment Form is assumed to be the extent of documentation needed. Consultation must be completed prior to requesting a project-level air quality conformity determination from the Federal Highway Administration(FHWA). Subtask 4.9 Noise Impact Report&Noise Abatement Decision Report. The project would add lanes in the interchange area;therefore,the project is a Type I undertaking under Title 23 Code of Federal Regulations Part 772.Noise abatement is to be considered and a Noise Study Report(NSR)is required in accordance with the 2011 Traffic Noise Analysis Protocol(TNAP). A Noise Abatement Decision Report will also be prepared to evaluate the feasibility and reasonableness of noise barriers under 2011 TNAP criteria, and will be provided as an appendix of the NSR.
