Summary of proposal
Because Louisville has been designated nonattainment by EPA for the 2015 ozone NAAQS, the District is required to implement an NNSR program. Due to previous nonattainment ozone designations, the District has an existing NNSR program. The District continues to operate under the provisions approved by EPA. Therefore, the District is certifying that no further actions are necessary to satisfy the NNSR requirements for the 2015 ozone marginal nonattainment areas.
The District previously shared an Advance Notice of Proposed Rulemaking (ANPR) for an updated version of Regulation 2.04. The District intends to continue working toward proposed revisions and make a formal proposal in the coming months. However, to meet the required deadline for a SIP submittal, the District is proposing submitting this certification in the meantime.
Who is affected by this rule?
Regulation 2.04 only applies to new major sources and major modifications in nonattainment areas.
Will this action lead to an increase or decrease in emissions?
Because no changes are being proposed and this certification would not affect the more stringent requirements contained in other District requirements such as the Strategic Toxic Air Reduction (“STAR”) Program or the standards for existing and new facilities in Parts 6 & 7 of the District’s Regulations, no emissions changes are anticipated.
What is the timeline for this action?
The District is seeking feedback on this proposal until May 18, 2021. The District is required to submit a final rule or certification to the Kentucky Division for Air Quality (DAQ) in time for the state to make a final SIP submittal to EPA by August 3, 2021, the deadline imposed due to the area’s designation as nonattainment.
