Title 6 › Chapter 4— TRANSPORTATION SECURITY › Subchapter III— PUBLIC TRANSPORTATION SECURITY › § 1139
The Secretary must make sure the Department of Transportation gets timely notice of any credible terrorist threats to public transportation in the United States. The Secretary must pay reasonable costs for the Information Sharing and Analysis Center for Public Transportation (ISAC), which shares security information. Public transportation agencies the Secretary finds to be high risk must join the ISAC. Other agencies should be encouraged to join. Nonprofit labor groups that represent transit workers should also be encouraged. The Secretary may not charge a fee to participate in the ISAC. The Comptroller General must report to Congress at least 3 years after August 3, 2007 about how well the ISAC and other DOT information-sharing programs work. The report must cover user satisfaction, costs and benefits, coordination among programs, how each helps carry out the information-sharing plan under section 1203, and whether the ISAC duplicates other programs. Congress authorized $600,000 for each of fiscal years 2008, 2009, and 2010, and whatever is needed for 2011 if the report is submitted. Those funds remain available until spent.
