Project Overview

• Project Need: Current trains are overloaded beyond BART and FTA’s standards.

• Project Purpose: To provide additional capacity through the operation of more frequent, longer trains.

• Project Objective: Increase capacity from 24 to 30 TPH, and make all peak trains 10-car trains.

Why more substations?1. Increased power draw from:

• 23 TPH 30 TPH• 8/9/10 car trains all 10 car

trains• Higher performance new cars

2. Address low voltage segments of system.

3. TPSS 4 and 5 needed to allow for closure and rehabilitation of existing TPSS equipment at Powell.

30 TPH Service Requires 5 New Traction Power Substations (TPSS)

Air Quality Conformity Status

• Project has plan-level conformity - full project is included in Plan Bay Area 2040 adopted by MTC, and so is included in a conforming regional plan.

• Project-level conformityo HMC Phase 2 has existing CE under 23 CFR 771 and is thus

exempt per 40 CFR 93.126.o Train control modernization (CBTC) and traction power

improvements are exempt from conformity per 40 CFR 93.126.o Acquisition of 306 new rail vehicles is not considered to be a minor

expansion, and therefore is not exempt. Project-level conformity determination is needed for this element.

20

Is this a project of air quality concern?

Not a Project of Air Quality Concerno Not a new or expanded highway project.o No effect on intersections (no changes to parking).o No changes to rail or bus terminals or transfer points are

included in project, and none are anticipated.o No modifications to bus operations are part of the

project, and none are anticipated. o No effect on PM emissions.

All BART vehicles are electrically-powered. Slight reduction of VMTs possible.

22

Connecting Buses

22

No changes to bus network are included in project (BART does not operate buses).

Bus changes generally happen as part of large bus network restructuring projectso Concentrate service on frequent, high density corridors.o Reduce low-frequency coverage service in low-density areas.o SFMTA (Muni Forward), AC Transit (ACgo), VTA (Next Network).o Reaction to changing ridership patterns, different housing patterns,

and competition from TNCs.o Subject to independent environmental review and AQ findings.

Bus Technologyo Evolving to low/zero-emission – hybrids, hydrogen.

Note – This reduction is from approx45,000 daily trips down to approx32,000 daily trips.

Conclusion

27

• BART’s Transbay Corridor Core Capacity Project will implement much needed capacity relief on the BART system. As an electrically-powered rail system, BART’s operation has no detrimental effects on air quality.

• Expansion of the fleet by 306 rail vehicles is a critical component of expanding the system’s capacity.

• Requesting a finding that BART’s Transbay Corridor Core Capacity Project is not a project of air quality concern.

• Questions?
