Today EPA is staying the effectiveness of subpart I of 40 CFR part 61, the National Emission Standards for Hazardous Air Pollutants for Radionuclide Emissions (54 FR 51654, December 15, 1989) as applied to facilities licensed by the Nuclear Regulatory Commission or an Agreement State ("NRC-licensed facilities"), other than nuclear power reactors, until November 15, 1992. The purpose or this rule is to afford EPA the time required to make an initial determination pursuant to section 112(d)(9) of the 1990 Clean Air Amendments before subpart I becomes effective for such facilities. EPA intends to propose a rule pursuant to section 112(d)(9) to rescind subpart I for nuclear power reactors, and to take final action no later than June 30, 1991, concerning a separate proposal to stay the effectiveness of subpart I for nuclear power reactors during the pendency of the rulemaking on recission. This rule staying subpart I for NRC-licensed facilities other than nuclear power reactors, and the Agency's final action on its proposal to stay subpart I for nuclear power reactors, will completely supplant all stays previously entered for such facilities during the Agency's reconsideration of subpart I under Clean Air Act section 307(d)(7)(B).
