National Emission Standards for Hazardous Air Pollutants for
Source Categories: Gasoline Distribution (Stage I)

AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule amendments.

SUMMARY: This action amends the ``National Emission Standards for
Hazardous Air Pollutants for Source Categories: Gasoline Distribution
(Stage I)'' (the ``Gasoline Distribution NESHAP''). These final
amendments extend the initial compliance date for the equipment leak
provisions applicable to existing sources to no later than December 15,
1997, and amend the date by which an existing facility must provide an
initial notification to December 16, 1996 or 1 year after a facility
becomes subject to the Gasoline Distribution NESHAP, whichever is
later.

DATES: Effective Date. February 29, 1996.
Judicial Review. Under section 307(b)(1) of the Clean Air Act
(Act), judicial review of NESHAP is available only by filing a petition
for review in the U.S. Court of Appeals for the District of Columbia
Circuit within 60 days of today's publication of these final
amendments. Under section 307(b)(2) of the Act, the requirements that
are the subject of this document may not be challenged later in civil
or criminal proceedings brought by the EPA to enforce these
requirements.

I. Background and Final Rule Amendments

A. Background

On December 14, 1994 (59 FR 64303), the EPA promulgated the
``National Emission Standards for Hazardous Air Pollutants for Source
Categories: Gasoline Distribution (Stage I)'' (the ``Gasoline
Distribution NESHAP''). The Gasoline Distribution NESHAP regulates all
hazardous air pollutants (HAP) emitted from new and existing bulk
gasoline terminals and pipeline breakout stations that are major
sources of HAP emissions or are located at sites that are major sources
of HAP emissions. Among the promulgated requirements for existing
sources under this rule are the requirements that sources institute an
equipment leak prevention program and provide an initial notification
of regulatory status no later than December 14, 1995 (40 CFR
Secs. 63.424(e) and 63.428(a)).

On November 7, 1995 (60 FR 56133), the EPA proposed amendments to
the Gasoline Distribution NESHAP. The EPA proposed to amend the initial
compliance date for the equipment leak provisions applicable to
existing sources from no later than December 14, 1995 to no later than
December 15, 1997, and to amend the date by which an existing facility
must provide an initial notification to December 16, 1996 or 1 year
after a facility becomes subject to the Gasoline Distribution NESHAP,
whichever is later. Those modifications were proposed because the
compliance date for these provisions was approaching and the EPA
believes that, under current circumstances, additional time will allow
sources a better opportunity to establish major or area source status
without forgoing quantifiable emissions reductions.
On December 8, 1995 (60 FR 62991), the EPA issued a partial 3-month
stay of the December 14, 1995 compliance date for equipment leak
prevention provisions and providing an initial notification of
regulatory status and use of a screening equation in the Gasoline
Distribution NESHAP. The December 14, 1995 compliance date for leak
detection and repair provisions and initial notifications was stayed
for existing facilities until March 7, 1996. The EPA issued the stay
pursuant to Clean Air Act section 307(d)(7)(B), 42 U.S.C.
7607(d)(7)(B), which provides the Administrator authority to stay the
effectiveness of a rule during reconsideration.

B. Summary of Amendments

After considering all of the comments, both for and against the
proposed amendments, the EPA is promulgating these rule amendments as
they were proposed. The EPA consideration and response to all the
comments are contained in the next section of this document. In
summary, the final amendments consist of two new compliance dates in
the promulgated rule: the initial compliance date for the equipment
leak provisions (Sec. 63.424(e)) applicable to existing sources is no
later than December 15, 1997, and the date by which an existing
facility must provide an initial notification (Sec. 63.428(a)) is
December 16, 1996 or 1 year after a facility becomes subject to the
Gasoline Distribution NESHAP, whichever is later. This action also
clarifies that all initial notifications are to be submitted by the
same time (December 16, 1996) as intended at proposal and noted in the
stay. The EPA is promulgating this related clarifying amendment that
extends the notification for area source facilities using an emission
screening equation (Sec. 63.428 (i)(1) and (j)(1)) to that same date.
The EPA continues to believe that, under current circumstances, this
additional time is needed to allow sources a better opportunity to
establish major or area source status without forgoing quantifiable
emissions reductions.

II. Comments on the Proposed Amendments

A. Public Participation

These amendments were proposed in the Federal Register on November
7, 1995 (60 FR 56133). Public comments were solicited at the time of
proposal. Electronic versions of the preamble and proposed regulatory
amendments were made available to interested parties immediately after
signature (on November 2, 1995) via the TTN bulletin board (see
ADDRESSES section of this preamble for more TTN information).
The preamble to the proposed amendments provided the public the
opportunity to request a public hearing. However, a public hearing was
not requested. The public comment period for the proposed amendments
was from November 7, 1995 until December 7, 1995 and the document was
available to the public on the TTN even earlier, as of November 2,
1995. In all, 13 comment letters were received. The comments have been
carefully considered in arriving at the final amendments being
promulgated in this document.

B. Comments Received on the Proposed Amendments

Comments on the proposed amendments were received from 13
commenters, consisting of oil

[[Page 7720]]

companies (10), trade organizations (2), and one environmental
organization. Most of the commenters were in general agreement with the
proposed amendments. Due to the small number of comments received, and
the fact that technical issues were not involved, no background
information document (BID) was prepared to present more detailed
comments and responses.

However, the original comment letters have been placed in the
docket, which is referred to in the ADDRESSES section of this preamble.
For summary purposes, all of the comments have been grouped by the
topic areas they address, and are discussed in the next section.

C. Summary of Comments and EPA Responses

As mentioned in the previous section, all but one of the commenters
expressed general agreement with the proposed amendments to the
Gasoline Distribution (Stage I) NESHAP. A summary of the major comments
and the EPA's responses is presented below.
(1) Opportunity for Comment

One commenter considered the comment period for the proposal to be
inadequate to allow most citizens to comment on the proposal, since it
frequently requires a week or more for the Federal Register to arrive
at public libraries, and another week or more for placement on library
shelves. This leaves less than 2 weeks to research, write, edit, and
mail comments. This commenter also felt that most citizens were
unlikely to have learned of the opportunity to request a public hearing
before the deadline for requesting such a hearing expired. However, the
commenter did not request extension of the time to comment.
The EPA placed the proposal preamble and amendments on the TTN on
November 2, 1995, 1 day after it was signed by the Administrator. The
TTN is an electronic (computer) bulletin board, free to users, and is
available on the Internet for use by the public. The usual comment
period (30 days beginning with publication of the proposal in the
Federal Register) and opportunity for requesting a hearing were
provided at the time of proposal. No person contacted the EPA to
request more time to comment. The time period was consistent with the
requirements of section 307 of the Act. The EPA did not provide a
longer comment period due to the relative narrowness and simplicity of
the proposal and the proximity of the compliance dates. For these
reasons, the EPA believes that a reasonable amount of time was afforded
the public for commenting on the proposal.
(2) Extension of Deadline for Initial Notification
Twelve of the commenters expressed support for the proposed
amendment to the initial notification date for existing sources. Most
said that the change was essential to provide many bulk terminals and
pipeline breakout stations a reasonable opportunity to calculate their
potential to emit and to determine the applicability of the NESHAP.
Four commenters supported the non-binding clause of the initial
notification, feeling that such a clause will encourage would-be major
sources to consider pollution prevention opportunities or additional
controls prior to the December 15, 1997 compliance date. Commenters
also pointed out that the amended notification date would not have any
adverse impact on the environment. Potential negative consequences of
not finalizing the amendment cited by commenters included the erroneous
classification of many facilities as major sources due to the short
time available to establish area source status, and the avoidance of
these terminals by outside tank truck firms not wishing to incur the
vapor tightness testing obligations associated with affected terminals.
The EPA is promulgating the amendment to the initial notification
deadline for existing sources as it was proposed: 1 year after an
affected source becomes subject to the NESHAP or by December 16, 1996,
whichever is later. In addition, the clause specifying that
declarations of major source status submitted by this deadline will be
considered non-binding for 1 year has been retained in the final
amendments. This means that facilities that include in their
notification a brief description and schedule for their planned actions
for achieving area source status by December 15, 1997 can make a change
to their status until this latter deadline. The EPA believes that
although the information in the notifications may change, it provides
necessary information for tank truck companies in planning their vapor
tightness testing schedules and for Federal, State, and local air
pollution control agencies in planning for rule implementation and
compliance activities.

(3) Extension of Initial Compliance Date for Leak Detection and Repair
(LDAR)

Twelve of the commenters also supported the proposed amendment to
the initial compliance date, which affects only periodic visual
inspection programs for leaks from gasoline equipment components. These
commenters said that the change was essential to provide many terminals
and pipeline breakout stations a reasonable chance to demonstrate that
they are not major sources subject to the NESHAP, and to allow time for
the resolution of the potential to emit issue (see next comment topic).
One commenter stated that this amendment would provide State and local
agencies additional time to develop EPA-approved federally enforceable
State operating permit (FESOP) programs and to complete permit
processing. Another company said that EPA approvals of its 33 FESOP and
15 Title V permit actions have been very slow and the company would not
be able to obtain these permits by the promulgated first compliance
date of December 14, 1995. The company felt that this date extension
would give them a reasonable opportunity to obtain approval of
artificial limits on potential to emit from most, if not all, of the
appropriate State agencies. Commenters believed that having a common
compliance date for all aspects of the regulation would allow more time
for facility owners and operators to consider pollution prevention
opportunities or additional controls. A number of commenters pointed
out that equipment leak emissions represent a minor portion of a
facility's total HAP emission inventory, and most facilities already
have some type of routine visual inspection program. Therefore, the
proposed change would have no long-term adverse impact on human health
or the environment.

One commenter, however, expressed concern that the EPA, by delaying
the initial compliance date, would put citizens at risk on the basis of
the already high levels of benzene and other gasoline components in the
air around terminals.

The EPA has considered all of these comments, including the comment
opposing the compliance date extension. The EPA continues to believe
that deferral of the compliance date for the equipment leak provisions
for existing sources until December 15, 1997 is the most appropriate
way to allow sources a better opportunity to establish major or area
source status without forgoing quantifiable emissions reductions. The
EPA also agrees with commenters that equipment leak emissions are
relatively small under normal operations, and so delaying compliance
with the visual inspection requirement for major source facilities will
not produce any significant increase in risk to exposed populations.
(See the more complete discussion of risk under section (5) Risk
below.)

[[Page 7721]]

(4) Potential to Emit (PTE)

Several commenters took issue with the EPA's policy that only
federally enforceable control standards or operating limitations would
be considered in determining the potential to emit of facilities and,
consequently, whether they would be a major source and subject to the
NESHAP. Four commenters cited a decision by the U.S. Court of Appeals
for the District of Columbia Circuit ruling that the EPA's stand on the
issue is unlawful, which the commenters interpreted to indicate that
the policy has been vacated and is no longer in effect. One commenter
stated that the EPA's insistence on maintaining its policy on this
matter creates confusion on the part of facilities potentially subject
to this rule. Three other commenters said that requiring federally
enforceable emission controls in determinations of potential to emit
inflates emission estimates, which could cause area sources to be
classified as major sources required to undertake unnecessary controls
and programs. Two commenters concluded that the EPA should allow
permitting authorities to take into account State and local controls
that the permitting authority deems effective in limiting facilities'
potential to emit.

The EPA's proposal to amend the Gasoline Distribution NESHAP
focused narrowly on the issue of modifying compliance dates for two
provisions, the equipment leak inspection requirements and the
notification of major source status, rather than the distinct issues of
whether the emission screening equation and the emissions inventory
methods of calculating potential to emit should be revised to reflect
limitations on emissions that are not federally enforceable, and
whether Federal enforceability should be a necessary criterion for
determination of potential to emit under section 112 in general. Thus,
comments regarding these latter two issues are outside the scope of the
topics raised by the proposal. However, the EPA believes it is useful
in response to these comments to summarize the impact of the court
decision referenced by commenters, as well as related EPA guidance
recognizing State-enforced PTE limits under section 112 during a
transition period.

The EPA interpreted the impact of the referenced court decision in
a January 22, 1996 guidance memorandum, which is contained in the
docket and is also available on the TTN (see ADDRESSES section). The
memorandum stated that, in National Mining Association v. EPA, 59 F.3d
1351 (D.C. Cir. 1995), the court addressed regulations under subpart A
of 40 CFR part 63, the ``General Provisions'' of hazardous air
pollutant programs under section 112. The court found that the EPA had
not adequately explained why only federally enforceable measures should
be considered as limits on a source's potential to emit. Accordingly,
the court remanded the section 112 General Provisions regulation to the
EPA for further proceedings. The EPA must either provide a better
explanation as to why Federal enforceability promotes the effectiveness
of State controls, or remove the exclusive Federal enforceability
requirement. The court did not vacate the section 112 regulations; that
is, the court did not declare the regulations null and void. The
regulations remain in effect pending completion of new rulemaking.
The EPA plans to hold discussions with stakeholders and propose
rulemaking amendments by spring 1996, and to issue final rules by
spring 1997, that would address the court decisions impacting
regulations promulgated pursuant to section 112 as well as other air
act provisions. The EPA currently plans to address the following
options, after discussions with stakeholders:
(a) An approach that would recognize ``effective'' Stateenforceable
limits as an alternative to federally enforceable limits on
a source's potential to emit. Under this option, a source whose maximum
capacity to emit without pollution controls or operational limitations
exceeds relevant major source thresholds may take a State or local
limit on its potential to emit. In such circumstances, the source must
be able to demonstrate that the State-enforceable limits are (1)
enforceable as a practical matter, and (2) being regularly complied
with by the facility.

(b) An approach under which the EPA would continue to require
Federal enforceability of limits on a source's potential to emit. Under
this approach, in response to specific issues raised by the court in
National Mining, the EPA would present further explanation regarding
why the Federal enforceability requirement promotes effective controls.
Under this approach, the EPA would propose simplifying changes to the
administrative provisions of the current Federal enforceability
regulations.

Any method for limiting potential to emit made available as a
result of the EPA's response to the NMA remand will be available to
sources in the Gasoline Distribution (Stage I) source category. The EPA
expects to respond to the remand in NMA with adequate time to allow
such sources to seek any new methods developed.
The EPA today reiterates that independent from the decision in
National Mining, current EPA policy already recognizes Stateenforceable
PTE limits under section 112 in many circumstances under a
transition policy intended to provide for orderly implementation of
these new programs under the Clean Air Act Amendments of 1990. This
policy is set forth in a memorandum, ``Options for Limiting the
Potential to Emit (PTE) of a Stationary Source Under Section 112 and
Title V of the Clean Air Act'' (January 25, 1995), and has been amended
in one significant way by the January 22, 1996 guidance memorandum as
noted below. (Both memoranda are contained in the docket and are also
available on the TTN, see ADDRESSES section.)
Under the terms of the EPA's transition policy, the transition
period is to end in January 1997. In addition, completion of the EPA's
rulemaking in response to the recent court decisions, which the EPA
anticipates will occur by early 1997, may render the transition policy
unnecessary after that time. However, in conjunction with the
rulemaking, the EPA will consider whether it is appropriate to extend
the transition period beyond January 1997.
In recognition of the absence in some States of suitable federally
enforceable mechanisms to limit PTE applicable to sources that might
otherwise be subject to section 112 or Title V, the EPA's policy
provides for the consideration of State-enforceable limits as a gapfilling
measure during a transition period that extends until January
1997. Under this policy, for the 2-year transition period, restrictions
contained in State permits issued to sources that actually emit more
than 50 percent, but less than 100 percent, of a relevant major source
threshold are treated by the EPA as acceptable limits on potential to
emit, provided: (a) the permit and the restriction in particular are
enforceable as a practical matter, and (b) the source owner submits a
written certification to the EPA accepting EPA and citizen enforcement.
In light of National Mining, the EPA believes that the certification
requirement is no longer appropriate as part of this policy.
Accordingly, under the January 1996 guidance, the EPA amended the
January 1995 transition policy by deleting the certification
requirement.

In addition, under the transition policy, sources with consistently
low levels of actual emissions relative to major source thresholds can
avoid major source requirements even absent any permit or other
enforceable limit on PTE. Specifically, the policy provides

[[Page 7722]]

that sources which maintain their emissions at levels that do not
exceed 50 percent of any applicable major source threshold are not
treated as major sources and do not need a permit to limit PTE, so long
as they maintain adequate records to demonstrate that the 50 percent
level is not exceeded.

The EPA's action in this rule to extend the compliance dates for
the two provisions will give more opportunities for sources to obtain
potential to emit limits consistent with the EPA's guidance and hence
avoid being subject to regulation as major sources.
One commenter disagreed with the EPA's interpretation that if a
facility does not demonstrate area source status by the first
substantive compliance date, then the facility, regardless of actual
emissions or any subsequent State operating permit limitation, would be
permanently classified as a major source.
The EPA's interpretation was explained in an EPA guidance
memorandum from John S. Seitz, ``Potential to Emit for MACT Standards--
Guidance on Timing Issues'' (May 16, 1995), which is contained in the
docket (item no. VI-B-6) and is also available on the TTN (see
ADDRESSES section). The EPA notes that the commenter viewed finalizing
the proposed amendments to the compliance dates as a ``critical need *

* [to] avoid unintended inclusion of area sources.'' For the
facilities in this source category, the EPA and many commenters believe
that delaying the first compliance date will provide the relief being
sought by the above commenters.

A number of commenters noted that the emission screening equation
in the final rule cannot be used by bulk terminals because essentially
all terminals handle non-gasoline products, such as diesel fuel or home
heating oil, which makes them ineligible to use the equation. The
commenters urged the EPA to reexamine the issue of which facilities are
eligible to use the equation, pointing out that the HAP emitted from
these products are ``de minimis'' and should not compel facilities to
use the more cumbersome and costly emissions inventory mechanism for
determining potential to emit.

As discussed in the proposal preamble, the EPA is considering data
and information submitted by the API (and available in the docket) in
order to evaluate a possible expansion of the screening equation to
include non-gasoline products that emit HAP, and will make a final
decision about changes to the equation under a separate action. The EPA
is still reviewing this information and is not prepared to discuss any
specific changes to the equation at this time. Depending on the results
of its review of the pertinent data, the EPA may propose changes to the
equation and request comment in a forthcoming and separate action in
the Federal Register.

(5) Risk

One commenter opposed the proposal to delay the initial compliance
date for the NESHAP on the grounds that the health risk to populations
exposed to ambient HAP concentrations near terminals would be
increased. The commenter expressed a belief that the language and
legislative history of the Clean Air Act reflects a Congressional
intent to limit public exposures to carcinogens to a level that will
not produce a lifetime risk of cancer at a rate greater than one in a
million. According to the commenter, a 50-year lifetime constant
exposure to a gasoline vapor concentration of 0.639 part per billion
(ppb) would correspond to the Act's one-in-a-million lifetime risk
standard. The commenter cited a 1993 air quality study at the Paw Creek
terminals in North Carolina that indicated a maximum benzene
concentration of 2.2 ppb, which they claimed corresponds to a lifetime
cancer risk of at least 131 per million. The commenter concluded that
emission levels corresponding to such risks ought to be reduced as
quickly as possible.

The EPA has not performed a risk analysis to allow the EPA to
verify the risk estimation results cited by the commenter, nor did the
commenter include a copy of the study with their comments. However, in
accordance with sections 112 (d)(6) and (f)(2) of the Act, the Gasoline
Distribution NESHAP will be reviewed within 8 years after the date of
promulgation (i.e., by December 14, 2002). This review may include an
assessment of residual health risk, in addition to many other aspects
of the regulation. As discussed above, the proposal and this final
action only extend the compliance time for instituting programs to
perform visual inspections and subsequent repair of equipment
components in gasoline service at terminals and pipeline breakout
stations. Most facilities are already carrying out similar informal
programs and, furthermore, data show that the HAP emissions from this
equipment in normal operation are very low. The compliance date of
December 15, 1997 promulgated in the final rule for the remaining
emission sources at bulk terminals will not be affected by this action.
Due to these factors, the EPA believes that this action will not
substantially change the emissions near major source gasoline
distribution facilities. For these reasons, the EPA is finalizing the
extension of the compliance date for LDAR until December 15, 1997 as
proposed on November 7, 1995.

III. Administrative Requirements

A. Paperwork Reduction Act

The information collection requirements of the previously
promulgated NESHAP were submitted to and approved by the Office of
Management and Budget (OMB). A copy of this Information Collection
Request (ICR) document (OMB control number 2060-0325) may be obtained
from Ms. Sandy Farmer, Information Policy Branch, Environmental
Protection Agency, 401 M Street., S.W. (mail code 2136), Washington, DC
20460, or by calling (202) 260-2740.

Today's amendments to the Gasoline Distribution NESHAP have no
impact on the information collection burden estimates made previously.
No additional certifications or filings were promulgated. Therefore,
the ICR has not been revised.

B. Executive Order 12866

Under Executive Order 12866 (58 FR 51735, October 4, 1993), the EPA
must determine whether a regulation is ``significant'' and therefore
subject to OMB review and the requirements of the Executive Order. The
criteria set forth in section 1 of the Order for determining whether a
regulation is a significant rule are as follows:
(1) Is likely to have an annual effect on the economy of $100
million or more, or adversely and materially affect a sector of the
economy, productivity, competition, jobs, the environment, public
health or safety, or State, local, or tribal government communities;
(2) Is likely to create a serious inconsistency or otherwise
interfere with an action taken or planned by another agency;
(3) Is likely to materially alter the budgetary impact of
entitlements, grants, user fees, or loan programs or the rights and
obligations of recipients thereof; or

(4) Is likely to raise novel or policy issues arising out of legal
mandates, the President's priorities, or the principles set forth in
the Executive Order.

The Gasoline Distribution NESHAP promulgated on December 14, 1994,
was treated as a ``significant regulatory action'' within the meaning
of the Executive Order. An estimate of the cost and benefits of the
NESHAP was prepared at proposal as part of the

[[Page 7723]]

background information document (BID) and was updated in the BID for
the final rule to reflect comments and changes to the final rule. The
amendments issued today have no impact on the estimates in the BID. The
EPA's earlier estimates of costs and emission reductions were based on
the Gasoline Distribution NESHAP affecting only major sources and did
not quantify the emission reductions associated with the visual
equipment leak detection program; in any event, these emission
reductions are small relative to the total reduction for the source
category.

Pursuant to the terms of Executive Order 12866, it has been
determined that this action is a ``non-significant regulatory action''
within the meaning of the Executive Order. As such, this action was not
submitted to OMB for review.

C. Regulatory Flexibility Act

The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires the
EPA to consider potential impacts of regulations on small business
entities. The Act specifically requires the preparation of a Regulatory
Flexibility Analysis in those instances where small business impacts
are possible. When the EPA promulgated the Gasoline Distribution
NESHAP, it analyzed the potential impacts on small businesses,
discussed the results of this analysis in the Federal Register, and
concluded that the promulgated regulation would not result in financial
impacts that significantly or differentially stress affected small
companies. Since today's action imposes no additional impacts, a
Regulatory Flexibility Analysis has not been prepared.
Pursuant to the provisions of 5 U.S.C. 605(b), I hereby certify
that this rule will not have a significant economic impact on a
substantial number of small business entities.

D. Unfunded Mandates Act

Under section 202 of the Unfunded Mandates Reform Act of 1995
(Unfunded Mandates Act), signed into law on March 22, 1995, the EPA
must prepare a budgetary impact statement to accompany any proposed or
final rule that includes a Federal mandate that may result in estimated
costs to State, local, or tribal governments in the aggregate, or to
the private sector, of $100 million or more. Under section 205, the EPA
must select the most cost effective and least burdensome alternative
that achieves the objectives of the rule and is consistent with
statutory requirements. Section 203 requires the EPA to establish a
plan for informing and advising any small governments that may be
significantly or uniquely impacted by the rule.
The EPA has determined that today's action does not include a
Federal mandate that may result in estimated costs of $100 million or
more to either State, local, or tribal governments in the aggregate, or
to the private sector. Therefore, the requirements of the Unfunded
Mandates Act do not apply to this action.

E. Regulatory Review

In accordance with sections 112(d)(6) and 112(f)(2) of the Act,
this regulation will be reviewed 8 years from the date of promulgation.
This review may include an assessment of such factors as evaluation of
the residual health risk, any overlap with other programs, the
existence of alternative methods of control, enforceability,
improvements in emission control technology and health data, and the
recordkeeping and reporting requirements.
