A new law directs federal agencies to encourage the use of remanufactured parts to maintain fleet vehicles, which is expected to reduce the cost of federal fleet maintenance. President Obama signed the Federal Vehicle Repair Cost Savings Act of 2015 on Oct. 7.

Using remanufactured parts could cut individual parts costs by up to 50%, according to MiBiz.com.

The law, first introduced in the Senate in February, directs federal agencies to encourage the use of remanufactured parts to maintain vehicles if such components reduce the maintenance cost while maintaining quality. It defines the “remanufactured vehicle component” as a part that has been returned to same-as-new or better condition and performance.

The U.S. Postal Service and the U.S. Department of the Interior already use remanufactured parts to reduce costs, according to text in the law.

In 2014, the worldwide federal fleet consisted of 633,851 vehicles, and agencies spent nearly $1.2 billion in maintenance, according to the 2014 Federal Fleet Report from the U.S. General Services Administration. The report shows that even though the federal fleet has decreased since 2011, maintenance costs have been rising consistently since then.
