TURN states that it is a "customer" within the meaning of the intervenor compensation statute, and the organization has previously submitted the relevant portion of its articles of incorporation (which have not changed) to the Commission in proceedings Application (A.) 98-02-017 and A.99-12-024. TURN indicates that it has approximately 30,000 dues-paying members; and, although it does not survey its members, TURN believes that the vast majority are residential utility customers. Thus, TURN argues that, while other organizations participated in this proceeding, it is the sole representative of the residential customer class. TURN is a Category 3 customer.
