Presentation of Air Quality Initiatives Report AGENDA ITEM 8 Presentation of Air Quality Initiatives Report Transportation Policy Council October 28, 2016

Air Quality Initiatives Report Work with partners to meet air quality commitments and reduce emissions Documents emissions reductions resulting from clean air programs These projects are funded by CMAQ, STP, SEP, TCEQ, USEPA, and USDOE

Voluntary Mobile Emissions Reductions 1.11

On-Road Emission Reductions 0.91 H-GAC provides: CMAQ: retrofit and replace high-emitting heavy-duty diesel vehicles or engines on the road and around the ports SEP: replace old school buses with lower emission buses

Commute Alternatives 0.174 Reduce emissions from vehicles and traffic congestion Education through public outreach events and coordination with other partners

Off-Road Emission Reductions 0.04 Provide grant assistance for governments and businesses to replace marine engines and construction equipment with cleaner engines.

Other Emission Reduction Efforts Additional emission reductions not funded by H-GAC that improve air quality:

NOx Reductions (tons/day) 1997 NAAQS SIP Commitments NOX REDUCTION MEASURE NOx Reductions (tons/day) ON-ROAD EMISSION REDUCTIONS - Clean Vehicles & School Bus Replacements 0.53 - Drayage Trucks 0.38 Total 0.91 COMMUTE ALTERNATIVES - METRO STAR Vanpool 0.08 - Carpool Ridesharing 0.05 - Telework, Compressed Work Week, Bike/Ped 0.04 - Commuter and Transit Services Pilots 0.004 0.174 OFF-ROAD EMISSION REDUCTIONS - Clean Vessels and Equipment UNFUNDED EMISSION REDUCTIONS Total 1.436 TOTAL 2.56

Next Steps Design value for region is 80 ppb Region unable to attain 2008 standard (75 ppb) by July 2016 Region reclassified from Marginal to Moderate for 2008 standard More stringent 2015 standard established at 70 ppb New standard will require additional emission reductions

Upcoming SIP Dates Date 2008 Standard 2015 Standard 1/1/2017 10/1/2017 Moderate SIP Due 10/1/2017 Finalize Designation & Implementation Rules 7/20/2018 Attainment Deadline for Moderate 10/1/2019 Likely Attainment Deadline for Marginal 10/1/2020 10/1/2023 Likely Attainment Deadline for Moderate
