Standards of Performance for New Stationary Sources (NSPS); Supplemental Delegation of Authority to the State of Oklahoma

The purpose of this document is to inform the public that the EPA approved the updated delegation of authority to the State of Oklahoma for implementation and enforcement of NSPS. This action is in response to a request from the Oklahoma Department of Environmental Quality (ODEQ). On November 2, 1998, the State of Oklahoma approved an emergency rule that incorporates by reference EPA's New Source Performance Standards in 40 CFR part 60. Both emergency and permanent rules incorporating by reference the NSPS were adopted by the Environmental Quality Board on September 15, 1998 and the permanent rules took effect June 1, 1999. The State adopted all of the NSPS except subpart AAA, New Residential Wood Heaters, and those sections that contain authorities reserved by the EPA.
