Designated Federal Officer
Tania Carreón-Valencia

The Administrator of the WTC Health Program is responsible for appointing members to the STAC. The make-up of the STAC is specified in the James Zadroga 9/11 Health and Compensation Act of 2010. Due to a recent change in the STAC Charter, the term of a committee member may last up to four years (except for some members whose term is 3 years). If a vacancy occurs, the Administrator of the WTC Health Program will appoint a new member in the same area of expertise as the individual they replace. Once a member has completed their term, they may be appointed to additional terms.

Below is the current list of STAC members and their affiliations arranged by area of expertise:
