EPA is taking direct final action approving State Implementation Plan revisions submitted by the State of Colorado on August 3, 2007 to Colorado's Regulation Number 1 (revisions to the performance testing requirements for air curtain destructors). Colorado adopted these rule revisions on October 2, 2006. All other actions submitted by the State of Colorado concurrent with Colorado's Regulation Number 1 revision request will be acted Start Printed Page 25773on at a later date. This action is being taken under section 110 of the Clean Air Act.
EPA is approving a revision to the Colorado State Implementation Plan Start Printed Page 25774(SIP). On August 3, 2007, the State of Colorado submitted a revision to its SIP, regarding the applicability provisions for incinerator performance testing requirements. This revision addressed Regulation Number 1 of the Colorado Air Quality Control Commission (AQCC) Regulations, entitled “Emission Control for Particulate Matter, Smoke, Carbon Monoxide, and Sulfur Oxides.” Colo. Code Reg. § 1001-3, and provides an exemption for air curtain destructors.
Under the definition set forth in Colorado's Common Provisions Regulation, 5 Colo. Code. Regs. § 1001-2, air curtain destructors are considered incinerators, if they are subject to New Source Performance Standards (NSPS) for incinerators in 40 CFR part 60. However, at the time Section III.B of Regulation 1 was enacted, there were no federal NSPS requirements governing air curtain destructors. Air curtain destructors were not considered incinerators and were not subject to 40 CFR part 60. On December 1, 2000, EPA promulgated NSPS for Commercial and Industrial Waste Incineration Units at 40 CFR part 60, subpart CCCC. On December 16, 2005, EPA promulgated NSPS for Other Solid Waste Incineration Units at 40 CFR part 60, subpart EEEE. Both standards apply to air curtain destructors that meet limited applicability criteria and establish opacity standards and appropriate performance testing requirements for those units.
EPA considers this change to be consistent with the provisions in CAA § 110(l). CAA Section 110(l) states: “Each revision to an implementation plan submitted by a State under this chapter shall be adopted by such State after reasonable notice and public hearing. The Administrator shall not approve a revision of a plan if the revision would interfere with any applicable requirement concerning attainment and reasonable further progress (as defined in section 7501 of this title), or any other applicable requirement of this chapter.” Thus, under Section 110(l), this SIP revision must not interfere with attainment or reasonable further progress or any other applicable requirement of the Act. When Section III.B was approved into Colorado's SIP, air curtain destructors were not subject to any 40 CFR part 60 requirements. Before EPA's promulgation of 40 CFR part 60, subpart CCCC and 40 CFR part, 60 subpart EEEE, air curtain destructors would not have been considered “incinerators” under the definition in the Common Provisions Regulation, 5 Colo. Code Regs. § 1001-2, and no air curtain destructors would have been regulated under Section III.B. Therefore, this revision exempting air curtain destructors from the requirements of Section III.B does not substantively change the requirements of Colorado's SIP. Because EPA's approval of this SIP revision would not interfere with reasonable further progress or any other applicable requirement of CAA, it is consistent with CAA § 110(l).
