The SCCWRP Commission’s Technical Advisory Group (CTAG) is the scientific advisory committee to the SCCWRP Commission. Each of SCCWRP’s 14 member agencies appoints one representative to CTAG. The panel holds quarterly meetings at SCCWRP approximately one month prior to Commission meetings, to review SCCWRP science, collaborate and partner on emerging research initiatives, make recommendations on forthcoming agenda items, and discuss and set priorities for future research.
