EPA Approves Requests from
                 Florida  and North Carolina to Relax
                 the Summer Gasoline Volatility
                 Standard for Florida and the Raleigh-
                 Durham-Chapel Hill Area and the
                 Greensboro/Winston-Salem/High
                 Point Area  in North  Carolina
                    The U.S. Environmental Protection Agency (EPA) is issuing a
                    final rulemaking to relax the applicable RVP standard in Florida
                 and in the Triangle and Triad Areas in North Carolina, during the
                 summer season (June 1st to September 15th).

                 Summary
                 The EPA is approving a request from Florida to relax the federal Reid Vapor Pressure
                 (RVP) standard applicable to gasoline introduced into commerce in the Miami,
                 Tampa and Jacksonville areas. The EPA is also approving a similar request from
                 North Carolina to relax the RVP standard in the Triangle and Triad Areas. These
                 changes apply during the  summer high ozone season - June 1st to September 15th,
                 This action amends our regulations to change the summertime RVP standard for
                 these areas from 7.8 pounds per square inch (psi) to 9.0 psi. The EPA has determined
                 that this change to our federal RVP regulations is consistent with the applicable
                 provisions of the Clean Air Act. The requests from Florida and North Carolina dem-
                 onstrate that all of these areas can implement the 9.0 psi RVP standard and maintain
                 the 8-hour ozone NAAQS.

                 Key Elements
                      This rule relaxes the volatility requirements for gasoline in three areas in
                      Florida and two areas in North Carolina as described above, during the
                      summer (June 1st  to September 15th). The final rule will become effective on
                      May 30, 2014. It is beneficial to these areas because the action will improve

       the fungibility of gasoline. In other words when this rule becomes effective the gasoline
       sold in these areas will be identical to the fuel sold now in the rest of Florida and in most
       of North Carolina. For motorists the change in summertime gasoline volatility specifica
       tions will be virtually unnoticeable,

       All of these areas have attained the health'based ozone NAAQS. This rule was dependent
       upon the  approval of revisions of maintenance plans and a demonstration that each area
       would maintain the ozone NAAQS using gasoline that meets the less stringent require-
       ment. Florida submitted the revised maintenance plans and maintenance demonstrations
       in August 2013 and North Carolina made its submissions in March 2013 for the Triangle
       Area and in April 2013  for the Triad Area.  Region 4 approved Florida's submission in
       January 2014 (79 FR 573). The Region approved North Carolina's submissions for the
       Triangle and Triangle Areas in January 2014 (79 FR 47  and  79 FR 4082, respectively).
Background
In 1987, EPA determined that gasoline nationwide had become increasingly volatile, causing an
increase in evaporative emissions from gasoline-powered vehicles and equipment. Evaporative
emissions from gasoline, referred to as volatile organic compounds (VOCs), are precursors to
the formation of tropospheric ozone and contribute to the nation's ground'level ozone problem.
Ground-level ozone causes health problems, including damaged lung tissue, reduced lung
function, and lung sensitization to other pollutants.

To provide for cleaner air and greater public health protection, EPA enforces maximum limits
for the RVP (the most common measure of fuel volatility) of gasoline sold during the summer
ozone control season - June 1st to September 15th. EPA's current regulations establish maximum
RVP standards of 9.0 psi or 7.8 psi (depending on the State, the month, and the area's initial
ozone attainment designation with respect to the 1'hour ozone National Ambient Air Quality
Standard or "NAAQS") during the ozone control season.

In order to relax the applicable RVP standard in an area where the more stringent RVP level is
required, an area must be designated as (or redesignated to) attainment and submit a mainte-
nance plan demonstrating continued attainment of the ozone NAAQS with the less stringent
RVP standard in place. All of these areas are designated as attainment areas for the 2008 ozone
NAAQS as well as the earlier 1997 8-hour ozone NAAQS and the 1-hour ozone NAAQS. As
described above all of these areas have demonstrated that they will continue to attain the ozone
NAAQS after the summertime RVP limit has been relaxed.
