III. Background and Proposal
A

. Summary of the Proposal The EPA is proposing to approve a request from the s tate of North Carolina to change the summertime RVP standard for Mecklenburg and Gaston counties , North Carolina from 7.8 psi to 9.0 psi by amending the EPA’s regulations at 40 CFR 80.27(a)(2). In a previous rulemaking, the EPA approved a redesignation request and maintenance plan for the Charlotte

- interference demonstration that relaxing the f

ederal RVP requirement from 7.8 psi to 9.0 psi for gasoline sold from June
1 to September 15 of each year in Mecklenburg and Gaston counties would not interfere with maintenan ce of any NAAQS in the Charlotte area, including the 2008 ozone NAAQS, or with any other applicable CAA requirement

- 0275 for the rulemaking that was signed on July 17, 2015. The preamble for this rulemaking is organized as follows: Section III.B. provides the history of the federal gasoline volatility regulation. Section III.C. describes the policy regarding relaxation of gasoline volatility standards in ozone nonattainment a reas that are redesignated as attainment areas. Section III.D. provides information specific to NorthPage 6 of 13 This document is a prepublication version, signed by EPA Administrator, Gina McCarthy, on 8/5/2015. We have taken steps to ensure the accuracy of this version, but it is not the official version. Carolina’s request for Mecklenburg and Gaston counties

. Finally, Section IV. briefly discusses the associated direct final rule.
B. History of the Gasol ine Volatility Requirement On August 19, 1987 (52 FR 31274), the EPA determined that gasoline nationwide was becoming increasingly volatile, causing an increase in evaporative emissions from gasoline

- powered vehicles and equipment. Evaporative emissions f rom gasoline, referred to as volatile organic compounds (VOC), are precursors to the formation of tropospheric ozone and contribute to the nation’s ground

- level ozone problem. Exposure to ground

level ozone can reduce lung function, thereby aggravating ast hma and other respiratory conditions, increase susceptibility to respiratory infection, and may contribute to premature death in people with heart and lung disease. The most common measure of fuel volatility that is useful in evaluating gasoline evaporati ve emissions is RVP. Under CAA section 211(c), the EPA promulgated regulations on March 22, 1989 (54 FR 11868) that set maximum limits for the RVP of gasoline sold during the regulatory control periods that were established on a state

- by

state basis in the final rule. The regulatory control periods addressed the portion of the year when peak ozone concentrations were expected. These regulations constituted Phase I of a two

- phase nationwide program, which was designed to reduce the volatility of gasoline dur ing the high ozone season. On June 11, 1990 (55 FR 23658), the EPA promulgated more stringent volatility controls as Phase II of the volatility control program. These requirements established maximum RVP standards of 9.0 psi or 7.8 psi (depending on the st ate, the month, and the area’s initial ozone attainment designation with respect to the 1

- hour ozone NAAQS.)Page 7 of 13 This document is a prepublication version, signed by EPA Administrator, Gina McCarthy, on 8/5/2015. We have taken steps to ensure the accuracy of this version, but it is not the official version. The 1990 CAA Amendments established a new section 211(h) to address fuel volatility. CAA section 211(h) requires the EPA to promulgate regulations making it unlawful to sell, offer for sale, dispense, supply, offer for supply, transport, or introduce into commerce gasoline with an RVP level in excess of 9.0 psi during the high ozone season. CAA section 211(h) also prohibits the EPA from establishing a volatility standard more stringent than 9.0 psi in an attainment area, except that the EPA may impose a lower (more stringent) standard in any former ozone nonattainment area redesignated to attainment. On December 12, 1991 (56 FR 64704), the EPA modified the Phase II volatility regulations to be consistent with CAA section 211(h). The modified regulations prohibited the sale of gasoline with an RVP above 9.0 psi in all areas designated attainment for ozone, effective January 13, 1992. For areas de signated as nonattainment, the regulations retained the original Phase II standards published on June 11, 1990 (55 FR 23658), which included the 7.8 psi ozone season limitation for certain areas. As stated in the preamble to the Phase II volatility control s and reiterated in the proposed change to the volatility standards published in 1991, the EPA will rely on states to initiate changes to their respective volatility programs. The EPA’s policy for approving such changes is described below in Section III.C. The s tate of North Carolina has initiated this change by requesting that the EPA relax the 7.8 psi gasoline RVP standard to 9.0 psi for Mecklenburg and Gaston counties , which are subject to the 7.8 gasoline RVP requirement during the summertime ozone

se ason . Accordingly, the s tate of North Carolina provided a technical demonstration showing that relaxing the federal gasoline RVP requirements in the two counties from 7.8Page 8 of 13 This document is a prepublication version, signed by EPA Administrator, Gina McCarthy, on 8/5/2015. We have taken steps to ensure the accuracy of this version, but it is not the official version. psi to 9.0 psi would not interfere with maintenance of any NAAQS in the Charlotte area, including the 2008 ozone NAAQS, or with any other applicable CAA requirement

. C

. The EPA’s Policy Regarding Relaxation of Gasoline Volatility Standards in Ozone Nonattainment Areas That Are Redesignated to Attainment Areas As stated in the preamble for the EPA’s amended Phase II volatility standards (56 FR 64706), any change in the gasoline volatility standard for a nonattainment area that was subsequently redesignated as an attainment area must be accomplished through a
sep arate rulemaking that revises the applicable standard for that area. Thus, for former 1

- hour ozone nonattainment areas where the EPA mandated a Phase II volatility standard of 7.8 psi RVP in the December 12, 1991 rulemaking, the federal 7.8 psi gasoline RV P requirement remain s in effect, even after such an area is redesignated to attainment, until a separate rulemaking is completed that relaxes the federal gasoline RVP standard in that area from 7.8 psi to 9.0 psi. As explained in the December 12, 1991 rul emaking, the EPA believes that relaxation of an applicable gasoline RVP standard is best accomplished in conjunction with the redesignation process. In order for an ozone nonattainment area to be redesignated as an attainment area, CAA section 107(d)(3) requires the state to make a showing, pursuan t to CAA section 175A, that the area is capable of maintaining attainment for the ozone NAAQS for ten years. Depending on the area’s circumstances, this maintenance plan will either demonstrate that the area is capable of maintaining attainment for ten years without the more stringent volatility standard or that the more stringent volatility standard may be necessary for the area to maintain its attainment with the ozone NAAQS. Therefore, in the context of a requ est for redesignation, the EPA willPage 9 of 13 This document is a prepublication version, signed by EPA Administrator, Gina McCarthy, on 8/5/2015. We have taken steps to ensure the accuracy of this version, but it is not the official version. not relax the gasoline volatility standard unless the state requests a relaxation and the maintenance plan demonstrates to the satisfaction of the EPA that the area will maintain attainment for ten years without the need for the more stringent volatility standard. North Carolina is requesting relaxation of the federal gasoline RVP standard from 7.8 psi to 9.0 psi for Mecklenburg and Gaston counties concurrent with its request that the EPA approve a redesignat ion request and maintenance plan for the Charlotte area for the 2008 ozone NAAQS

. D

. North Carolina’ s Request to Relax the Federal Gasoline RVP Requirement for Mecklenburg and Gaston Counties On March 11 , 201 5 , the s tate of North Carolina , through the North Carolina Department of Environment and Natural Resources ( NCDENR) , submitted a redesignation request and mai ntenance plan for the Charlotte area , which was classified

as M arginal for the 2008 ozone NAAQS. Mecklenburg and Gaston counties are part of the Charlotte area. Additionally, the state submitted a CAA section 110(l) non

interference demonstration that removal of the federal RVP requirement of 7.8 psi for gasoline duri ng the summertime ozone season in Mecklenburg and Gaston counties would not interfere with maintenance of any NAAQS , or with any other applicable CAA requirement

. Specifically, the state provided a technical demonstration showing that relaxing the federal gasoline RVP requirement in the two counties from 7.8 psi to 9.0 psi would not interfere with maintenance of any NAAQS in the Charlotte area, of which the two counties are part, including the 2008 ozone NAAQS, or with any other applicable CAA requirement

In this action, the EPA is taking the second and final step in the process by proposing to approve North Carolina’s request to relax the summertime oz one season gasoline RVP standard for Mecklenburg and Gaston counties from 7.8 psi to 9.0 psi. Specifically, the EPA is proposing to amend the applicable gasoline RVP standard to allow the gasoline RVP requirements to rise from 7.8 psi to 9.0 psi provided at 40 CFR 80.27(a)(2) for the two counties

. This proposal to approve North Carolina’s request to
relax the summertime ozone season gasoline RVP standard for Mecklenburg and Gaston counties from 7.8 psi to 9.0 psi is based on the previous approval of North Carolina’s

It is also based on the fact that the Charlotte area is currently in attainment for the both the 1997 ozone NAAQS and the 2008 ozone NAAQS

. IV. Direct Final Rule A direct final rule that would make the same changes as those proposed in this action appears in the Rules and Regulations section of this Federal Register . The EPA is taking direct final action on these revisions because the EPA views the revisions as noncontroversial and anticipates no adverse comment. The EPA has explained the reasons for the amendments in this proposal and in the direct final rule. If no adverse comments are received, no further action will be taken on the proposal, and the direct final rule will become effective as provided in that action. If the EPA receives adverse comments on the rule or any portion of the rule, the EPA will withdraw the direct final rule or the portion of the rule that received adverse comment. The EPA will publish a timely withdrawal in the Federal Register indicating

w hich provisions are being withdrawn. All public comments received will then be addressed in a subsequent final rule based on this proposed rule. The EPA will not institute a second comment period on the subsequent final action. Any parties interested in co mmenting must do so at this time. The changes to the regulatory text proposed in this document are identical to those for the direct final rule published in the Rules and Regulations section of this Federal Register .
