Supplemental Information to Support Proposed Approvals of One-
Hour Ozone Attainment Demonstrations for Serious Ozone Nonattainment
Areas

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice of availability and reopening of comment period.

-----------------------------------------------------------------------

SUMMARY: Notice is hereby given that EPA has performed an analysis to
evaluate emission levels of oxides of nitrogen ( NOX) and
volatile organic compounds (VOC) and their relationships to the
application of current and anticipated control measures expected to be
implemented in four serious one-hour ozone nonattainment areas. This
analysis was done to determine if additional reasonably available
control measures (RACM) are available after adoption of Clean Air Act
(Act) required measures for the following serious ozone nonattainment
areas: Greater Connecticut, New York-New Jersey-Connecticut;
Springfield, Massachusetts; Washington, D.C.-Virginia-Maryland; and
Atlanta, Georgia. The EPA performed this analysis in response to
comments that were submitted on the proposals on these areas' one-hour
ozone attainment demonstrations. The EPA took action to propose
approval (and disapproval in the alternative) of these areas' State
implementation plans (SIPs) on December 16, 1999 (Greater Connecticut
(64 FR 70332); Springfield (64 FR 70319); Metropolitan Washington (64
FR 70460); and Atlanta (64 FR 70478)). This information supplements the
December 16, 1999 proposals.

DATES: The EPA is establishing a comment period, ending on October 31,
2000. All comments should be sent to the appropriate regional office as
listed in the ADDRESSES section by that date.

ADDRESSES: Written comments on the Greater Connecticut and Springfield
SIPs should be sent (in duplicate if possible) to: David B. Conroy, EPA

this action are available for public inspection during normal business
hours at the following address: Air Protection Division, U.S.

    Written comments on the Atlanta SIP should be submitted (in
duplicate if possible) to: Scott M. Martin, EPA Region 4, Air Planning
Branch, 61 Forsyth Street, S.W., Atlanta, Georgia 30303. Copies of the
State submittal are available at the following address for inspection

SUPPLEMENTARY INFORMATION: Section 172(c)(1) of the Act requires SIPs
to contain reasonably available control measures (RACM) as necessary to
provide for attainment as expeditiously as practicable. Several
commenters have stated that there is no evidence in the four serious
ozone attainment demonstrations that were proposed on December 16, 1999
that they have adopted all RACM, and a commenter further stated that
the mobile source emission budgets in the SIPs are inadequate by
definition because the SIPs do not demonstrate timely attainment or
contain the emission reductions required for all RACM. In addition,
some commenters stated that for all potential RACM measures not adopted
into the SIP, the State must provide a justification for why they were
determined not to be RACM.
    The analysis EPA conducted demonstrates that a number of possible
emission control measures have been evaluated for their emission
reductions. It further demonstrates that the measures evaluated either
(a) are likely to require an intensive and costly effort for numerous
small area sources, or (b) do not advance the attainment dates for the
four areas, and therefore would not be considered RACM under the Act.
    EPA has previously provided guidance interpreting the RACM
requirements of 172(c)(1). See 57 FR 13498, 13560. In that guidance,
EPA indicated its interpretation that potentially available measures
that would not advance the attainment date for an area would not be
considered RACM. EPA concluded that a measure would not be reasonably
available if it would not advance attainment. EPA also indicated in
that guidance that States should consider all potentially available
measures to determine whether they were reasonably available for
implementation in the area, and whether they would advance the
attainment date. Further, States should indicate in their SIP
submittals whether measures considered were reasonably available or
not, and if measures are reasonably available they must be adopted as
RACM. Finally, EPA indicated that States could reject potential RACM
measures either because they would not advance the attainment date,
would cause substantial widespread and long-term adverse impacts, or
for various reasons related to local conditions, such as economics or
implementation concerns.

The EPA also issued a recent memorandum on this topic, ``Guidance on
the Reasonably Available Control Measures (RACM) Requirement and
Attainment Demonstration Submissions for Ozone Nonattainment Areas.''
John S. Seitz, Director, Office of Air Quality Planning and Standards,
dated November 30, 1999. A copy can be obtained from www.epa.gov/ttn/
oarpg/t1pgm.html.
    In response to public comments received on the proposed rulemakings
in December, EPA has reviewed the SIP submittals for the four serious
areas and determined that they did not include sufficient documentation
concerning available RACM measures. Therefore, EPA has itself reviewed
numerous potential RACM measures, as documented in the available
analysis. Based on this analysis, EPA concluded that these measures
would either (a) likely require an intensive and costly effort for
numerous small area sources, or (b) not advance the attainment date in
any of the four areas and, therefore, would not be considered RACM.
    Although EPA encourages areas to implement available RACM measures
as potentially cost effective methods to achieve emissions reductions
in the short term, EPA does not believe that section 172(c)(1) requires
implementation of potential RACM measures that either require costly
implementation efforts or produce relatively small emissions reductions
that will not be sufficient to allow any of the four areas to achieve
attainment in advance of full implementation of all other required
measures.
    Electronic Availability--An electronic version of EPA's RACM
analysis can be downloaded at www.epa.gov/ttn/rto under ``What's New.''
    For those persons without electronic capability, a copy of this
analysis may be obtained from Ms. Linda Lassiter at (919) 541-5526.
    The official record for these proposed actions have been
established under individual dockets which are located at the Regional
office address in the ADDRESSES section at the beginning of this
document. Electronic comments must be submitted as an ASCII file
avoiding the use of special characters and any form of encryption.
Comments and data will also be accepted on disks in WordPerfect file
format or ASCII file format. All comments and data in electronic form
must be identified by the docket number associated with the individual
state proposal.

    Dated: October 10, 2000.
