Three members from region number twelve comprised of the following States: Connecticut, Maine, Massachusetts, New Hampshire, New York, Rhode Island, and Vermont.

One member of the board shall be an importer who is subject to assessments under § 1150.152(b).

The Board shall be composed of milk producers and importers appointed by the Secretary either from nominations submitted pursuant to § 1150.133 or in accordance with § 1150.136. A milk producer may be nominated only to represent the region in which such producer's milk is produced.

At least every five years, and not more than every three years, the Board shall review the geographic distribution of milk production volume throughout the United States and, if warranted, shall recommend to the Secretary a reapportionment of regions and/or a modification of the number of producer members from regions in order to best reflect the geographic distribution of milk production volume in the United States.

At least once every three years, after the initial appointment of importer representatives on the Board, the Secretary shall review the average volume of domestic production of dairy products compared to the average volume of imports of dairy products into the United States during the previous three years and, on the basis of that review, if warranted, reapportion the importer representation on the Board to reflect the proportional shares of the United States market served by domestic production and imported dairy products. The basis for comparison of domestic production of dairy products to imported products shall be estimated total milk solids. The calculation of total milk solids of imported dairy products for reapportionment purposes shall be the same as the calculation of total milk solids of imported dairy products for assessment purposes.

In determining the volume of milk produced and total milk solids of dairy products produced in the United States, the Board and Secretary shall utilize the information received by the Board pursuant to § 1150.171(a) and data published by the Department.
