The Prince George's County Council has re-established the Emergency Medical Services Advisory Council (EMSAC).

The advisory council, which will meet at least quarterly, will be responsible for drafting an emergency medical health plan, designed to advise county officials about equipment necessary for effective emergency service.

In addition, the EMsAC will prepare an annual emergency health systems plan in conjunction with the county health officer. The plan will include recommendations on the types of services and equipment needed and an estimate of how much these items will cost.

At a hearing last week, 24 of the 26 people niminated to teh EMSAC by County Executive Winfield M. Kelly, Jr. were comfirmed. Of the two nominees not confirmed, Jeffrey T. Mitchell asked that he not be included as a voting member, and the nomination of John E. Piazza was withdrawn by Kelly. Mitchell will serve the board in an advisory capacity.
