PART 52—APPROVAL AND PROMULGATION OF IMPLEMENTATION PLANS


§52.420   Identification of plan.

(a) Purpose and scope. This section sets forth the applicable State implementation plan for Delaware under section 110 of the Clean Air Act, 42 U.S.C. 7410, and 40 CFR part 51 to meet national ambient air quality standards.

(b) Incorporation by reference. (1) Material listed in paragraphs (c) and (d) of this section with an EPA approval date prior to May 25, 2018, was approved for incorporation by reference by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR part 51. Entries in paragraphs (c) and (d) of this section with the EPA approval dates after May 25, 2018 for the State of Delaware have been approved by EPA for inclusion in the State implementation plan and for incorporation by reference into the plan as it is contained in this section, and will be considered by the Director of the Federal Register for approval in the next update to the SIP compilation.

(2) EPA Region III certifies that the materials provided by EPA at the addresses in paragraph (b)(3) of this section are an exact duplicate of the officially promulgated State rules/regulations which have been approved as part of the State implementation plan as of the dates referenced in paragraph (b)(1) of this section.

§52.433   Nonattainment new source review.

(a) Disapproval. EPA is disapproving Delaware's October 15, 2013 submittal of revisions to 7 DNREC 1125, sections 2.5.5 and 2.5.6 because it does not meet Clean Air Act (CAA) requirements which establish the criteria under which the owner or operator of a new or modified major stationary source must obtain the required emission offsets for the nonattainment new source review (NSR) preconstruction permitting program and because Delaware exercises authorities that are reserved for EPA under section 107 of the CAA. Delaware's Federally-approved nonattainment NSR preconstruction program in 7 DNREC 1125, sections 1.0 through 3.16.4, effective in Delaware on February 11, 2012, was fully-approved by EPA on October 2, 2012 and continues to apply.
