Since NEIWPCC’s formation in 1947, our Commissioners have played a critical role in setting NEIWPCC’s priorities, evaluating staff programs and projects, and representing their state’s interests.

35 commissioners—five from each member state—oversee NEIWPCC. Each commissioner is appointed by their state governor. A state’s delegation typically consists of the heads of its environmental and health agencies, who generally designate representatives to attend NEIWPCC meetings on their behalf, supplemented by three highly experienced individuals from outside state government. This approach provides NEIWPCC with diverse, expert leadership. The number of Commissioners from each state may vary from year to year due to the gubernatorial appointment process.

All of our Commissioners meet three times per year. The Executive Committee, a subset of the Commissioners which consists of the heads of our member states’ environmental agencies or their representatives, conducts four regular meetings annually.

Each year our Commissioners elect a chair and vice-chair, with these officer positions rotating among the states to ensure equal representation.
