Federal milk marketing order pooling issues have been frequent topics of discussion, especially since federal order reform was implemented in January 2000. Particularly controversial are depooling and distant pooling, both of which affect federal order producer prices. Numerous questions have been raised related to what is pooling, what producers are eligible to share in federal order pools, what is a pool milk plant, how do regulated manufacturing milk plants decide to pool or depool, and how does pooling affect producer pay prices, in particular the producer price differential (PPD) and the uniform producer price.
