Freight Wing, Interstate Distributor, anti pollution group partner in trailer skirt project

Partially funded by an $875,972 grant from the EPA’s Diesel Emissions Reduction Act (DERA) in a cost-sharing program, Interstate began installing 2,058 Freight Wing Aeroflex side skirts in July at its maintenance facilities.

SEATTLE – Interstate Distributor Co., Freight Wing and the Pacific Northwest Pollution Prevention Resource Center (PPRC), Thursday announced the beginning of one of the industry’s largest installations of trailer side skirts.

Partially funded by an $875,972 grant from the EPA’s Diesel Emissions Reduction Act (DERA) in a cost-sharing program, Interstate began installing 2,058 Freight Wing Aeroflex side skirts in July at its maintenance facilities.

Headquartered in Tacoma, Wash., Interstate Distributor Co. is North America’s 12th largest truck load carrier, and 46th largest for-hire carrier, with a fleet of more than 2,000 tractors and 6,800 trailers. 

“We greatly appreciate this opportunity presented to us by the EPA, and to work with PPRC and Freight Wing,” said Lee Owens, senior vice president of maintenance and facilities for Interstate Distributor Co.  “We expect great success with the project.”

According to Owens, the Freight Wing side skirts give a lot of bang for the buck when it comes to reducing fuel consumption and emissions.  “We’ve tested the side skirts for the past few years and have seen up to a 5 percent improvement in fuel economy depending upon the route and the speed we’re traveling.  The higher the average speed, the better the performance.  We also tested durability – a huge factor for us in deciding which side skirts to purchase.  We chose the Freight Wing product because it was more resilient than others we tested.”

The side skirts are constructed of durable plastic panels, combined with a flexible bracing system designed to absorb and deflect both ground and side impacts.

All told, Owens said that without the EPA grant, Interstate Distributor would be seeing a return on investment of less than two years.  With the grant, the time is cut by a third.  “We think it’s a great thing that the EPA is stepping up to help companies implement fuel and emission savings technology,” he said.  “Everyone wins and we hope grants continue for our industry to help the trucking community and the environment.”

According to Sean Graham, president of Freight Wing, the company’s Aeroflex side skirts reduce aerodynamic drag by preventing wind from hitting the trailer’s wheels and axles.  They have been SmartWay verified and tested to increase fuel economy by 7 percent in independent SAE/TMC J1321 track testing conducted by Energotest 2008.  “Track tests are done in a controlled environment at constant highway speeds.  In the real world, results can vary due to different average speeds, applications and driving environments.  Fleets and owner operators typically see anywhere from 4 to 7 percent improvements, with high mileage applications getting the best results.”

According to PPRC, the Interstate project is expected to save 1.1 million gallons of diesel a year, over 16 million gallons over the lifespan of the skirts, while preventing 182,633 tons of greenhouse gas emissions.

According to Dennis McLerran, EPA regional administrator in Seattle, PPRC offers both health and economic benefits to local communities when they help make trucks more streamlined and fuel-efficient.  “These aerodynamic upgrades reduce fuel consumption and save money,” said McLerran.  “By helping fleets update their vehicles, PPRC, through the DERA grant, provides much-needed assistance to the transportation industry, while reducing diesel pollution health risks in the communities it serves.”

Another EPA DERA opportunity is expected to be announced in October 2010.  Fleets need to work with a non-profit organization, such as PPRC, to apply for funding.   

“PPRC is delighted to partner with a company such as Interstate Distributor that has taken so many actions to become good environmental stewards.  We are excited to reduce its carbon footprint even further through the use of state-of-the-art trailer skirts,” said Paula J. Del Giudice, PPRC’s executive director.

According to Owens, Interstate will continue to outfit its remaining long-haul trailers with side skirts after this project is completed.  “The benefits are too big to ignore,” he said.  “We see the future for aerodynamic technologies as a key ingredient for reduction of green house gases and reduction of carbon footprint.  Our plan is to be 100 percent compliant with the CARB mandate as it is presented now.”

The implementation of side skirts is a continuation of forward-thinking by Interstate, which has a long history when it comes to improving productivity and fuel economy.  “We were quick to join the SmartWay initiative, becoming members in 2004 Owens said.  “Over the past five years we’ve seen overall fuel economy improve by more than 1 mile per gallon to the high 6’s.  We run aerodynamic models from Freightliner, Volvo and Kenworth equipped with power and drive train components to maximize fuel efficiency.”

In addition, the Interstate fleet runs with low rolling resistant tires and has idle reduction technology on board to lower idling rates.  According to Owens, the fleet has  implemented engine shut down parameters after five minutes of idle when a truck is equipped with an APU or shore/battery power that takes over heating/cooling duties from the main engine.  “On our APU-equipped units we average 5.09 percent engine idle time,” said Owens.  “That’s phenomenal.”

So is the company’s commitment to driver education.  “We have peer groups and we closely monitor driver performance through telematics and engine data tracking.  In prior years, the gap between our best driver and worst driver in fuel economy would exceed 1 mpg.  But since we began monitoring, and mentoring through our peer group, that gap has closed significantly.  If you implement fuel-saving technology, correct equipment specifications and couple that with solid driver training, you will maximize fuel economy.”

Headquartered in Tacoma, Wash., Interstate Distributor Co. is a provider of transportation services including local, regional and transcontinental coverage, specialized, heavy-haul and refrigerated equipment, dedicated fleets, intermodal and logistics management services. With terminal and yard facilities located in all major markets throughout the United States, Western Canada and the Mexican border industry, IDC has grown to establish a national presence in the transportation industry.

Established in 1933, IDC currently has more than 2,700 employees and is one of the largest employers in Washington State. For more information visit Interstate Distributor Co. at www.intd.com.

Seattle-based Freight Wing was incorporated in 2003. The company’s mission is to provide practical fleet fuel savings through innovative improvements to the aerodynamic profile of semi trailers.  It manufactures and distributes a full line of fairings, including trailer side skirts, belly fairings, and gap fairings and customized products for a variety of trucking applications. Freight Wing products represent the most thoroughly evaluated aerodynamic trailer fairings available to the trucking industry. Multiple scientific testing projects, to validate fuel economy improvements, have been conducted by third parties including the U.S. Department of Energy, the EPA SmartWay Program and Transport Canada.

PPRC is a leading regional nonprofit that provides practical, on-the-ground technical assistance to businesses, public agencies, and nonprofits that are seeking to conserve resources and improve economic performance.
