Federal Register / Vol. 86, No. 106 / Friday, June 4, 2021 / Rules and Regulations Specifically, at two locations the preamble text states that the provision applies if the occurrence of a qualifying transaction is demonstrated to EPAs satisfaction and further states that the relevant former owners and operators are identified by reference to such demonstrations. See 86 FR at 23139, 23142. In fact, as adopted in the final regulatory text, the provision applies whenever a qualifying transaction has occurred, with no need for any specific demonstration. Further, the relevant former owners and operators are identified by reference to such transactions rather than by reference to any demonstrations. In order to avoid any confusion that might be caused by the incorrect references in the preamble to demonstrations, in this document EPA is revising the preamble text to remove the incorrect references.
No change is being made to the regulatory requirements adopted in the final rule as already reflected in the regulatory text. This correction applies only to the preamble text, and the purpose of the correction is to make the preamble consistent with the existing regulatory language. This change is not to the rule itself and thus does not require the opportunity for notice and comment. Even if this change were considered to be a rule, notice and comment would be unnecessary because this is a minor technical correction that does not substantively alter the regulation. See 5 U.S.C. 553bB. This correction will become effective along with the rule on June 29, 2021.

ACTION: Final rule.
AGENCY:

The Environmental Protection Agency EPA is finalizing approval of a State Implementation Plan SIP
revision submitted by the State of Florida, through the Florida Department of Environmental Protection FDEP, on January 23, 2020. The SIP revision updates the attainment emissions inventory and the maintenance demonstration, including the projected future emissions inventories, in the maintenance plan for the Hillsborough County lead maintenance area hereinafter referred to as the Hillsborough Area or Area for the 2008 lead national ambient air quality standards NAAQS. The SIP revision also incorporates recent changes to the air construction permit for the EnviroFocus Technologies, LLC
EnviroFocus facility in the Area that are related to an increase in the refined lead production limit. EPA believes that this SIP revision meets all relevant Clean Air Act CAA or Act statutory and regulatory requirements, is consistent with EPAs guidance, and is in accordance with EPAs September 11, 2018, redesignation of the Hillsborough Area from nonattainment to maintenance.

SUPPLEMENTARY INFORMATION:
I. Background On November 12, 2008 73 FR 66964, EPA promulgated a revised primary and secondary lead NAAQS of 0.15
micrograms per cubic meter mg/m3.
Under EPAs regulations at 40 CFR part 50, the 2008 lead NAAQS are met when the maximum arithmetic 3-month mean concentration for a 3-year period, as determined in accordance with Appendix R of 40 CFR part 50, is less than or equal to 0.15 mg/m3. See 40 CFR
50.16. Ambient air quality monitoring data for the 3-year period must meet a data completeness requirement.
EPA designated the Hillsborough Area 1 as a nonattainment area for the 2008 lead NAAQS on November 22, 2010 75 FR 71033, effective December 31, 2010, using 20072009 ambient air quality data. This established an attainment date of five years after the December 31, 2010, effective date for the 2008 lead nonattainment designations pursuant to CAA section 172a2A.
Therefore, the Hillsborough Areas attainment date was December 31, 2015.
On April 16, 2015 80 FR 20441, EPA
published a final rule that approved a SIP revision, comprised of an attainment plan, based on Floridas attainment demonstration for the Hillsborough Area that included the base year emissions inventory requirements, a modeling demonstration of attainment for the 2008 lead NAAQS, reasonably available control measure requirements that included reasonably available control technology, a 1 The Hillsborough Area is comprised of a portion of Hillsborough County in Florida bounded by a 1.5
km radius centered at Universal Transverse Mercator coordinates 364104 meters East, 30093830
meters North, Zone 17, which surrounds Envirofocus.
