## CMAQ in Texas

- Four non attainment areas
- Beaumont-Port Arthur
- Dallas-Fort Worth
- El Paso
- Houston-Galveston
- $104 million dollar program (2003)
- State divides money based on federal formula

## Truck Stop Electrification

## Truck Stop Electrification

- Allows truck drivers ability to heat/cool cabs when stopped without running their engines
- Emissions reductions, noise benefits, cost effective
- IdleAire rolling out system across country
- Other shorepower alternatives

## Truck Stop Electrification

## Truck Stop Electrification- El Paso

- 250 IdleAire Spaces
- $2.5 million
- County took lead
- FHWA worked with county on contract language (public private partnership agreement)
- Eligibility issues worked out with FHWA and EPA headquarters offices

## Truck Stop Electrification- Beaumont

- Area in conformity lapse
- Need to pass build/no build test
- Limited options in small metro area
- EPA guidance on emissions reductions
- 135 g/hr valid 2002 through 2030
- Capped at 3.4% of NOx HDDV8a and 8b

## Truck Stop Electrification- Beaumont

| Network Year | NOx Reductions Needed | TSE Units | IdleAire Reductions |
| --- | --- | --- | --- |
| 2005 | 6 pounds | 2 | 7 pounds |
| 2015 | 424 pounds | 57 | 204 pounds* |
| 2025 | 229 pounds | 20 | 70 pounds* |

- * Emissions reductions limited to 3.4% of HDDV 8a and 8b emissions per EPA guidance.

## Truck Stop Electrification- Beaumont

- TSE project enables area to pass 2005 test
- TSE plus speed limit enforcement strategy for 2015 and 2025
- Looking into question about IdleAire making profits if project not competitively bid

## Clean Vehicles Program - Houston

- Approx. $50 million STP and CMAQ
- CMAQ pays for engine replacement cost
- Mostly accelerated retirement
- Some clean fuels
- Public school systems, Houston Metro,  and private fleets
- 1.97 tons/day current projects ($36.75 million CMAQ)

## Clean Vehicles Program - Houston

- 5-6 school contracts this year
- 80 Buses Houston ISD
- $1.8 million CMAQ
- .035 tons/day NOx reductions
- 41 Buses Clear Creek ISD
- $770,000 CMAQ
- .014 tons/day NOx reductions
- School districts poor
- Run buses to the ground
- Limited matching funds

## Clean Vehicles Program - Houston

- Silver Eagle Distributors (Budwiser)
- 1st Contract 26 trucks
- 3 gram NOx engines plus PM filters (’96-’03 engine standard was 4 gram NOx)
- $357,00 CMAQ
- .024 tons/day NOx reductions
- 2nd Contract 69 trucks
- 2.5 gram NOx engines (‘04 standard)
- $2.08 million CMAQ
- .039 tons/day NOx reductions

## Clean Vehicles Program - Houston

- HEB (Texas Grocery Chain)
- 42 Duel Fuel Conversions from Diesel
- 80% LNG (uses most of the time)
- 20% Diesel (for start up)
- LNG Fueling Station Upgrade
- $1.77 million CMAQ, matched with TERP
- .104 tons/day NOx

## Clean Vehicles Program - Houston

- Educate truck dealers about the program - they market it to individual fleets
- Issues:
- Aiming for 2007 emissions reductions.  How much longer can they do these contracts?
- Ensuring vehicle retirements are accelerated
- FHWA approves program as a whole, not each project
