On June 30, 2000, the State of South Dakota submitted a request for delegation of the New Source Performance Standards (NSPS) and requested that the NSPS be removed from the State Implementation Plan (SIP). On April 2, 2002, EPA delegated to the State of South Dakota the authority to implement and enforce the NSPS program. Since the State has been delegated the authority to implement and enforce the NSPS program, the intended effect of this action is to remove the NSPS sections from the SIP and also update the NSPS "Delegation Status of New Source Performance Standards" table. These actions are being taken under sections 110 and 111 of the Clean Air Act. Other parts of the June 30, 2000 submittal will be acted on in a separate notice.
