Jurisdiction source: House Rule X

How business reaches this committee

House Rule X gives this committee the subjects above. Each bill introduced in the House is referred to the committee whose Rule X jurisdiction covers its primary subject, and a bill that spans several subjects can go to more than one committee at once. This committee then decides whether to hold hearings, amend the text and report it to the floor.

Subcommittees

The committee divides its work among 7 subcommittees:

  • Subcommittee on Aviation
  • Subcommittee on Coast Guard and Maritime Transportation
  • Subcommittee on Economic Development, Public Buildings and Emergency Management
  • Subcommittee on Highways and Transit
  • Subcommittee on Oversight and Investigations
  • Subcommittee on Railroads, Pipelines, and Hazardous Materials
  • Subcommittee on Water Resources and Environment
