National Emission Standards for Hazardous Air Pollutants: Organic 
Liquids Distribution (Non-Gasoline)

AGENCY: Environmental Protection Agency (EPA).

ACTION: Direct final rule.

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

SUMMARY: EPA is taking direct final action on the national emission 
standards for hazardous air pollutants for organic liquids distribution 
(non-gasoline), which EPA promulgated on February 3, 2004, and amended 
on July 28, 2006. In this action, EPA is clarifying combustion control 
device compliance requirements, certain storage tank control compliance 
dates, and vapor balance system monitoring requirements. In addition, 
EPA is correcting typographical errors found in the July 28, 2006, 
final rule amendments.

DATES: This direct final rule is effective on July 22, 2008, without 
further notice, unless EPA receives adverse comment by June 9, 2008. If 
we receive adverse comment, we will publish a timely withdrawal in the 
Federal Register informing the public that this rule, or the relevant 
section of this rule, will not take effect.
    Public Hearing: If anyone contacts EPA requesting to speak at a 
public hearing concerning this rulemaking by May 5, 2008, we will hold 
a public hearing on May 8, 2008.

SUPPLEMENTARY INFORMATION:
    EPA is publishing this rule without prior proposal because we view 
this as a noncontroversial action and anticipate no adverse comment 
because the changes being implemented clarify the application of the 
rule, make the rule consistent with other regulations with no loss in 
its effectiveness in achieving emission reductions, and correct 
typographical and format errors. However, in the Proposed Rules section 
of this Federal Register, we are publishing a separate document that 
will serve as the proposed rule for these revisions if adverse comments 
are received on this direct final rule. If we receive adverse comment 
on a distinct section of this rule, we will publish a timely withdrawal 
in the Federal Register informing the public that some or all of the 
amendments in this rule will not take effect. The provisions that are 
not withdrawn will become effective on the date set out above, 
notwithstanding adverse comment on

[[Page 21826]]

any other provision, unless we determine that it would not be 
appropriate to promulgate those provisions due to their being affected 
by the provisions for which we receive any adverse comments. We will 
address all public comments in a subsequent final rule based on the 
proposed rule. We will not institute a second comment period on this 
action. Any parties interested in commenting must do so at this time. 
For further information about commenting on this rule, see the 
ADDRESSES section of this document.

I. Background

    On February 3, 2004 (69 FR 5063), EPA promulgated the National 
Emission Standards for Hazardous Air Pollutants: Organic Liquids 
Distribution (Non-Gasoline) (OLD NESHAP) (40 CFR part 63, subpart EEEE) 
pursuant to section 112 of the Clean Air Act (CAA). In response to 
several petitions for administrative reconsideration of the OLD NESHAP 
and several petitions for judicial review filed with the United States 
Court of Appeals for the District of Columbia Circuit, and pursuant to 
a settlement agreement between some of the parties to the litigation, 
EPA proposed amendments to subpart EEEE on November 14, 2005 (70 CFR 
69210). EPA received comments from four entities. On July 28, 2006 (71 
FR 42898), EPA promulgated amendments to subpart EEEE based on 
consideration of the comments received on the proposed amendments.

II. Summary of These Final Rule Amendments

    Under these final rule amendments, the following changes or 
clarifications are being promulgated.
     Removing the requirement that owners and operators must 
obtain prior approval from the Administrator to use total organic 
compounds (TOC) as a surrogate for hazardous air pollutants (HAP) when 
demonstrating compliance with the percent emission reduction 
requirements for combustion devices.
     Clarifying that demonstration of initial compliance for 
storage tanks that elect to comply with either the vapor balancing work 
practice requirement or the routing of emissions to a fuel gas system 
or back to a process work practice requirement must be made by April 
25, 2011, and not 10 years after February 3, 2004. We retain the 
requirement that compliance must occur prior to the specified date or 
the first degassing, whichever occur earlier.
     Clarifying that the continuous compliance requirements for 
the

[[Page 21827]]

monitoring of a transfer rack system using vapor balancing is for all 
points in the system that may leak and that monitoring is not required 
in any quarter in which loading does not occur.
    These final rule amendments also correct several format, 
grammatical, and typographical errors which occur in Table 2 (item 
9.b.ii), Table 5 (item 1.b), Table 6 (item 1), Table 7 (item 1.a.i, 
item 1.c.i, and item 2.a.i), and Sec.  63.2343(d).

III. Rationale for These Final Rule Amendments

A. Use of TOC as a Surrogate for HAP When Demonstrating Compliance With 
Percent Emission Reduction

    Section 63.2354(b) of the NESHAP specifies that you must comply 
with various requirements of 40 CFR part 63, subpart SS for performance 
testing provisions, including Sec.  63.997(e). Additionally, Sec.  
63.2346(f) specifies that if you elect to demonstrate compliance with 
the percent reduction requirements using TOC rather than organic HAP, 
you must first demonstrate, subject to approval of the Administrator, 
that TOC is an appropriate surrogate for organic HAP. This requirement 
was intended to address circumstances under which a device such as a 
condenser could achieve substantively different results from one 
compound to another. Under these conditions, an inlet and outlet 
percent control determination for TOC might not be equivalent to a 
similar determination for each or total HAP. Since promulgation, we 
have received questions on whether the requirement to first demonstrate 
that TOC is an appropriate surrogate for organic HAP is necessary for a 
combustion device. When organic compounds are controlled by combustion 
processes, the organic compounds emitted at the outlet of the device 
are not the same as those entering the inlet to the device and are 
typically unknown. Further, unlike non-combustion devices, combustion 
devices achieve a greater uniformity of destruction across all organic 
HAP compounds. Therefore, we have determined that the requirement to 
first demonstrate that TOC is an appropriate surrogate for organic HAP 
is unwarranted for combustion devices and have modified paragraph (f) 
of 40 CFR 63.2346 to make this requirement applicable only to non-
combustion devices.

B. Compliance Date and Initial Demonstration of Compliance for Storage 
Tanks Using Vapor Balancing or Routing Emissions Back to a Process or a 
Fuel Gas System

    Section 63.2342 identifies when an owner or operator must comply 
with the requirements of subpart EEEEE, while Sec.  63.2358 identifies 
the dates by which an owner or operator must demonstrate initial 
compliance. As discussed below, there is an inconsistency in these two 
sections of the rule as they apply to storage tanks for which vapor 
balancing or routing of emissions to a fuel gas system or back to a 
process are used to comply with the rule.
    Paragraph (b)(1) of Sec.  63.2342 states that owners or operators 
of existing affected sources must be in compliance with the emission 
limitations, operating limits, and work practice standards for existing 
sources by February 5, 2007, except as specified in Sec.  
63.2342(b)(2). Paragraph (b)(2) states that ``floating roof tanks at 
existing affected sources must be in compliance with the work practice 
standards in Table 4 to this subpart, item 1, at all times after the 
next degassing and cleaning activity or within 10 years after February 
3, 2004, whichever occurs first. If the first degassing and cleaning 
activity occurs during the 3 years following February 3, 2004, the 
compliance date is February 5, 2007.''
    With regards to demonstrating initial compliance, paragraph (c)(1) 
of Sec.  63.2358 states that ``for storage tanks at existing affected 
sources complying with the work practice standard in Table 4 to this 
subpart, you must conduct your initial compliance demonstration the 
next time the storage tank is emptied and degassed, but not later than 
10 years after February 3, 2004.'' The work practice standards in Table 
4 for storage tanks at existing facilities are:
     Comply with the requirements of 40 CFR part 63, subpart WW 
(control level 2), which addressed the use of floating roofs;
     Comply with the requirements of Sec.  63.984 for routing 
emissions to a fuel gas system or back to a process; and
     Comply with the requirements of Sec.  63.2346(a)(4) for 
vapor balancing emissions to the transport vehicle from which the 
storage tank is filled.
    As stated in the July 28, 2006, Federal Register in response to a 
public comment (71 FR 42899), the technical basis for allowing 
demonstration of initial compliance up to 10 years after February 3, 
2004, applies only to storage tanks with floating roofs and not to 
storage tanks with fixed roofs. EPA, in both the February 3, 2004 
rulemaking promulgating 40 CFR part 63, subpart EEEE, and in the July 
28, 2006 rulemaking promulgating amendments to 40 CFR part 63, subpart 
EEEE, inadvertently failed to revise Sec.  63.2358 to reflect its 
intent to apply the ``up to 10 years'' compliance provision to only the 
``floating roof'' work practice standard.
    As the current regulation stands, owners and operators seeking to 
comply with the work practice standards for storage tanks would have 
``up to 10 years'' to demonstrate initial compliance if they elect to 
comply by routing the emissions to a fuel gas system or back to a 
process or by using a vapor balancing system. This was never EPA's 
intent for these two types of work practice standards. EPA points out 
that these same types of work practice standards are allowed for 
transfer racks, and the rule is unambiguous that demonstration of 
initial compliance is required within 180 days after the compliance 
date of February 3, 2007.
    To correct this oversight, EPA is clarifying that the ``up to 10-
year'' demonstration of initial compliance date applies only when a 
floating roof is used to comply with 40 CFR part 63, subpart EEEE, and 
inserting the actual date ``February 3, 2014'' into the rule text. In 
addition, the intended compliance date has past (180 days after the 
compliance date of February 3, 2007) to demonstrate initial compliance 
if they elect to route storage tank emissions to a fuel system or back 
to a process or to use vapor balancing. Because facilities will need 
time to plan and install equipment and affected sources had up to 3 
years to comply with the original rule, we are specifying the 
compliance date for routing storage tank emissions to a fuel gas system 
or back to a process or to use vapor balancing to be 3 years from this 
notice. However, we retain and still require compliance by ``the next 
time the storage tank is emptied and degassed, but not later than'' 3 
years from this notice.

C. Monitoring of Vapor Balancing System Components With the Potential 
To Leak

    Table 10 to 40 CFR part 63, subpart EEEE addresses continuous 
compliance requirements, in part, for vapor balancing systems when used 
for transfer racks and storage tanks. EPA has received a question 
concerning the relationship between the continuous compliance 
requirements for vapor balancing systems and those for equipment leak 
components.

[[Page 21828]]

    For vapor balancing systems, there are two places in 40 CFR part 
63, subpart EEEE that identify compliance requirements--Table 10 and 
Sec.  63.2346(a)(4)(v). As found in item 4.b.i to Table 10, the 
continuous compliance requirement for a transfer rack using a vapor 
balancing system reads:
    ``Monitoring each potential source of vapor leakage in the system 
quarterly during the loading of a transport vehicle or the filling of a 
container using the methods and procedures described in the rule 
requirements selected for the work practice standard for equipment leak 
components as specified in Table 4 to subpart EEEE, item 4. An 
instrument reading of 500 ppmv defines a leak. Repair of leaks is 
performed according to the repair requirements specified in your 
selected equipment leak standards.''
    Paragraph (a)(4)(v) of Sec.  63.2346 identifies leak detection and 
repair (LDAR) requirements for pressure relief devices used in vapor 
balancing systems. The current rule language is, at best, ambiguous as 
to the relationship of this paragraph and the language in Table 10.
    For equipment leak components, which are defined in 40 CFR part 63, 
subpart EEEE as pumps, valves, and sampling connections, the owner or 
operator selects one of three 40 CFR part 63 subparts, as specified in 
item 4 of Table 4. These three subparts identify LDAR provisions that 
are to be applied to pumps, valves, and sampling connections.
    To clarify the intended relationship between these various 
provisions, the phrase ``each potential source of vapor leakage'' is 
intended to apply to any and all equipment in the vapor balancing 
system that may leak, including, but not limited to pumps, valves, and 
sampling connections. For all such equipment, the owner or operator is 
to apply the applicable provisions found in the equipment leak standard 
selected by the owner or operator to comply with the equipment leak 
components. This could mean that an owner or operator may be applying 
LDAR requirements found in the selected 40 CFR part 63 subpart for 
components other than a pump, valve, or sampling connection. If the 
vapor balancing system has a pressure relief valve, however, the owner 
or operator would comply with the LDAR provisions for pressure relief 
valves found in Sec.  63.2346(a)(4)(v). For equipment leak components 
(as defined in 40 CFR part 63, subpart EEEE) that are not part of a 
vapor balancing system, continuous compliance is demonstrated as 
specified in item 5 to Table 10.
    To clarify these relationships, EPA is revising item 4.b.i in Table 
10 or 40 CFR part 63, subpart EEEE to read as follows:
    ``Except for pressure relief devices, monitoring each potential 
source of vapor leakage in the system, including, but not limited to 
pumps, valves, and sampling connections, quarterly during the loading 
of a transport vehicle or the filling of a container using the methods 
and procedures described in the rule requirements selected for the work 
practice standard for equipment leak components as specified in Table 4 
to this subpart, item 4. An instrument reading of 500 ppmv defines a 
leak. Repair of leaks is performed according to the repair requirements 
specified in your selected equipment leak standards. For pressure 
relief devices, comply with Sec.  63.2346(a)(4)(v). If no loading of a 
transport vehicle or filling of a container occurs during a quarter, 
then monitoring of the vapor balancing system is not required.''
    Finally, item 6.b.i to Table 10 of 40 CFR part 63, subpart EEEE 
addresses the same vapor balancing system monitoring requirements, but 
for storage tanks. EPA is making the same changes as in item 4.b.i to 
Table 10. EPA is also making one additional change. As the rule 
currently reads, item 6.b.i refers to ``monitoring each potential 
source of vapor leakage in the system quarterly during the loading of a 
transport vehicle or the filling of a container.'' This item should be 
referring to the loading of a storage tank and not the loading of a 
transport vehicle or the filling or a container. Therefore, EPA is also 
correcting this incorrect reference.

D. Format, Grammatical, and Typographical Errors

    1. In Table 2, item 9.b.ii or 40 CFR part 63, subpart EEEE should 
have been placed on a separate line rather than on the same line as the 
end of item 9.b.i. For clarity, item 9.b.ii has been reformatted so 
that it starts on its own line.
    2. In Table 5 of 40 CFR part 63, subpart EEEE, the first two 
columns associated with item b. were incorrectly placed under the 
headings ``According to * * *'' and ``Using * * *''. They should have 
been placed under the headings, respectively, ``You must conduct * * 
*'' and ``According to * * *''.
    3. In Table 6, item 1 of 40 CFR part 63, subpart EEEE, the first 
column cross-references items 1 through 6 in Table 2. The sentence, 
therefore, should refer to ``meeting any set of tank capacity and 
liquid organic HAP vapor pressure criteria'' rather to ``meeting either 
set.''
    4. In Table 6 of 40 CFR part 63, subpart EEEE, the second column of 
item 1 states, in part, ``or as an option for combustion devices to an 
exhaust concentration of <=20 ppmv.'' The word ``nonflare'' was 
inadvertently omitted from this sentence. This sentence is revised to 
read, in part, ``or as an option for nonflare combustion devices to an 
exhaust concentration of <=20 ppmv.'' This makes the sentence 
consistent with the other items in Table 6.
    5. In Table 7 of 40 CFR part 63, subpart EEEE, three typographical 
errors are being corrected from the July 28, 2006, FR notice. In item 
1.a.i, ``perform'' was misspelled as ``perofrm.''. In item 1.c.i, the 
cross-reference was incorrectly identified as Sec.  3.2346(a)(4); the 
correct cross-reference is Sec.  63.2346(a)(4). In item 2.a.i, 
``primary'' was misspelled as ``priamry.''
    6. Section 63.2343(d) currently reads: ``If one or more of the 
events identified in paragraphs (d)(1) through (4) of this section 
occur since the filing of the Notification of Compliance Status or the 
last Compliance report, you must submit a subsequent Compliance report 
as specified in paragraphs (b)(3) and (c)(3) of this section.'' The 
cross-references to paragraphs (b)(3) and (c)(3) are incorrect. The 
correct cross-references are paragraphs (b)(2) and (c)(2). The direct 
final rule makes this correction.

IV. Statutory and Executive Order Reviews

A. Executive Order 12866: Regulatory Planning and Review

    This action is not a ``significant regulatory action'' under the 
terms of Executive Order 12866 (58 FR 51735, October 4, 1993) and is 
therefore not subject to review under the Executive Order.

B. Paperwork Reduction Act

    This action does not impose any new information collection burden. 
The final amendments clarify, but do not add requirements increasing 
the collection burden. However, the Office of Management and Budget 
(OMB) has previously approved the information collection requirements 
contained in the existing regulations at 40 CFR part 63, subpart EEEE 
under the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501, et 
seq., and has assigned OMB control number 2060-0539. The OMB control 
numbers for EPA's regulations in 40 CFR are listed in 40 CFR part 9.

C. Regulatory Flexibility Act

    The Regulatory Flexibility Act (RFA) generally requires an agency 
to prepare

[[Page 21829]]

a regulatory flexibility analysis of any rule subject to notice and 
comment rulemaking requirements under the Administrative Procedure Act 
or any other statute unless the Agency certifies that the rule will not 
have a significant economic impact on a substantial number of small 
entities. Small entities include small businesses, small organizations, 
and small governmental jurisdictions.
    For purposes of assessing the impacts of today's final rule 
amendments on small entities, a small entity is defined as: (1) A small 
business as defined by the Small Business Administration's (SBA) 
regulations at 13 CFR 121.201; (2) a small governmental jurisdiction 
that is a government of a city, county, town, school district or 
special district with a population of less than 50,000; or (3) a small 
organization that is any not-for-profit enterprise which is 
independently owned and operated and is not dominant in its field.
    The final rule amendments will not impose any new requirements on 
small entities, and, therefore, will have no significant adverse 
economic impact on subject small entities. The Administrator certifies 
that this action will not have a significant economic impact on a 
substantial number of small entities.

D. Unfunded Mandates Reform Act

    Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), Public 
Law 104-4, establishes requirements for Federal agencies to assess the 
effects of their regulatory actions on State, local, and tribal 
governments and the private sector. Under section 202 of the UMRA, EPA 
generally must prepare a written statement, including a cost-benefit 
analysis, for proposed and final rules with ``Federal mandates'' that 
may result in expenditures to State, local, and tribal governments, in 
the aggregate, or to the private sector, of $100 million or more in any 
1 year. Before promulgating an EPA rule for which a written statement 
is needed, section 205 of the UMRA generally requires us to identify 
and consider a reasonable number of regulatory alternatives and adopt 
the least costly, most cost-effective, or least burdensome alternative 
that achieves the objectives of the rule. The provisions of section 205 
do not apply when they are inconsistent with applicable law. Moreover, 
section 205 allows us to adopt an alternative other than the least 
costly, most cost-effective, or least burdensome alternative if the 
Administrator publishes with the final rule an explanation why that 
alternative was not adopted. Before we establish any regulatory 
requirements that may significantly or uniquely affect small 
governments, including tribal governments, we must have developed under 
section 203 of the UMRA a small government agency plan. The plan must 
provide for notifying potentially affected small governments, enabling 
officials of affected small governments to have meaningful and timely 
input in the development of EPA regulatory proposals with significant 
Federal intergovernmental mandates, and informing, educating, and 
advising small governments on compliance with the regulatory 
requirements.
    EPA has determined that these final rule amendments do not contain 
a Federal mandate that may result in expenditures of $100 million or 
more for State, local, and tribal governments, in the aggregate, or the 
private sector in any one year. These final rule amendments clarify 
certain provisions and correct typographical errors in the rule text 
for a rule EPA determined not to include a Federal mandate that may 
result in an estimated cost of $100 million or more (69 FR 5061, 
February 3, 2004). These clarifications do not change the level or cost 
of the standard, except, in some cases, reduce the cost of testing for 
combustion control devices at some facilities using that option. Thus, 
these final rule amendments are not subject to the requirements of 
section 202 and 205 of the UMRA. EPA has determined that these final 
rule amendments contain no regulatory requirements that might 
significantly or uniquely affect small governments. These final rule 
amendments clarify certain provisions and correct typographical errors 
in the rule text, thus, should not affect small governments.

E. Executive Order 13132: Federalism

    Executive Order 13132, entitled ``Federalism'' (64 FR 43255, August 
10, 1999) requires EPA to develop an accountable process to ensure 
``meaningful and timely input by State and local officials in the 
development of regulatory policies that have federalism implications.'' 
``Policies that have federalism implications'' is defined in the 
Executive Order to include regulations that have ``substantial direct 
effects on the States, on the relationship between the national 
government and the States, or on the distribution of power and 
responsibilities among the various levels of government.''
    These final rule amendments do not have federalism implications. 
They will not have substantial direct effects on the States, on the 
relationship between the national government and the States, or on the 
distribution of power and responsibilities among the various levels of 
government, as specified in Executive Order 13132. They provide 
clarification and correct typographical errors. These changes do not 
modify existing or create new responsibilities among EPA Regional 
Offices, States, or local enforcement agencies. Thus, Executive Order 
13132 does not apply to these final rule amendments.

F. Executive Order 13175: Consultation and Coordination With Indian 
Tribal Governments

    Executive Order 13175, entitled ``Consultation and Coordination 
with Indian Tribal Governments'' (65 FR 67249, November 9, 2000), 
requires EPA to develop an accountable process to ensure ``meaningful 
and timely input by tribal officials in the development of regulatory 
policies that have tribal implications.'' These final rule amendments 
do not have tribal implications, as specified in Executive Order 13175. 
They will not have substantial direct effects on tribal governments, on 
the relationship between the Federal government and Indian tribes, or 
on the distribution of power and responsibilities between the Federal 
government and Indian tribes. Thus, Executive Order 13175 does not 
apply to these final rule amendments.

G. Executive Order 13045: Protection of Children From Environmental 
Health Risks and Safety Risks

    EPA interprets Executive Order 13045 (62 FR 19885, April 23, 1997) 
as applying to those regulatory actions that concern health or safety 
risks, such that the analysis required under section 5-501 of the 
Executive Order has the potential to influence the regulation. This 
action is not subject to Executive Order 13045 because it is based 
solely on technology performance.

H. Executive Order 13211: Actions Concerning Regulations That 
Significantly Affect Energy Supply, Distribution, or Use

    These final rule amendments are not subject to Executive Order 
13211, ``Actions Concerning Regulations That Significantly Affect 
Energy Supply, Distribution, or Use'' (66 FR 28355, May 22, 2001) 
because they are not a significant regulatory action under Executive 
Order 12866.

I. National Technology Transfer and Advancement Act

    Section 12(d) of the National Technology Transfer and Advancement 
Act of 1995 (NTTAA), Public Law No. 104-113, 12(d) (15 U.S.C. 272 note)

[[Page 21830]]

directs EPA to use voluntary consensus standards (VCS) in its 
regulatory activities unless to do so would be inconsistent with 
applicable law or otherwise impractical. VCS are technical standards 
(e.g., materials specifications, test methods, sampling procedures, and 
business practices) that are developed or adopted by VCS bodies. NTTAA 
directs EPA to provide Congress, through OMB, explanations when the 
Agency decides not to use available and applicable VCS.
    This action does not involve technical standards. Therefore, EPA 
did not consider the use of any VCS.

J. Executive Order 12898: Federal Actions To Address Environmental 
Justice in Minority Populations and Low-Income Populations

    Executive Order 12898 (59 FR 7629, February 16, 1994) establishes 
Federal executive policy on environmental justice. Its main provision 
directs Federal agencies, to the greatest extent practicable and 
permitted by law, to make environmental justice part of their mission 
by identifying and addressing, as appropriate, disproportionately high 
and adverse human health or environmental effects of their programs, 
policies, and activities on minority populations and low-income 
populations in the United States.
    EPA has determined that these final rule amendments will not have 
disproportionately high and adverse human health or environmental 
effects on minority or low-income populations because it does not 
affect the level of protection provided to human health or the 
environment. These final rule amendments do not relax the control 
measures on sources regulated by the rule and, therefore, will not 
cause emissions increases from these sources.

K. Congressional Review Act

    The Congressional Review Act, 5 U.S.C. 801, et seq., as added by 
the Small Business Regulatory Enforcement Fairness Act of 1996, 
generally provides that before a rule may take effect, the agency 
promulgating the rule must submit a rule report, which includes a copy 
of the rule, to each House of the Congress and to the Comptroller 
General of the United States. EPA will submit a report containing the 
final rule amendments and other required information to the United 
States Senate, the United States House of Representatives, and the 
Comptroller General of the United States prior to publication of the 
final rule amendments in the Federal Register. A major rule cannot take 
effect until 60 days after it is published in the Federal Register. 
This action is not a ``major rule'' as defined by 5 U.S.C. 804(2). 
These final rule amendments will be effective on July 22, 2008.
