The oldest committee, Hart-Miller Island (HMI) Citizens Oversight Committee was statutorily created in 1981 to advise Maryland Port Administration (MPA) on dredged material placement activities at HMI as well as the monitoring program. Since dredged material placement was ceased at HMI in 2009, the HMI COC has been engaged in the development of the closure plan for the site and is working to create a Friends of Hart-Miller Island volunteer group.
