OSP oversees the STL program and, through its Regional Team and Science Policy Council, the Regional Science Liaison Program. STLs work with the Regional Science Liaisons on cross-program issues with the Regional Science Councils. These combined OSP programs strengthen scientific and technical cooperation between ORD, the regions, and State and local governments.
