National Emission Standards for Hazardous Air Pollutants:
Miscellaneous Organic Chemical Manufacturing

AGENCY: Environmental Protection Agency (EPA).
ACTION: Direct final rule; amendments.

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

SUMMARY: On November 10, 2003, EPA promulgated national emission
standards for hazardous air pollutants (NESHAP) for miscellaneous
organic chemical manufacturing under the authority of section 112 of
the Clean Air Act (CAA). We are amending the NESHAP by clarifying the
compliance requirements for flares and the alternative standard, which
limits the outlet concentration to 20 parts per million. We are
amending the NESHAP by extending the vapor balancing alternative to
cover transfers from barges to storage tanks, amending the procedures
for correcting measured concentrations at the outlet of combustion
devices to correct for dilution by supplemental gas, and clarifying the
signature requirements for the notification of compliance status
report. The direct final rule amendments also specify requirements for
effluent from control devices, clarify the definition of the term
continuous process vent, and correct several referencing and drafting
errors. We are issuing the amendments by direct final rule, without
prior proposal, because we view the revisions as noncontroversial and
anticipate no adverse comments.
In the Proposed Rules section of this Federal Register, we are
publishing a separate document that will serve as the proposal in the
event that timely adverse comments are received.

DATES: The direct final rule is effective on August 30, 2005, without
further notice, unless EPA receives adverse written comment by August
1, 2005, or if a public hearing is requested by July 11, 2005. If EPA
receives such comments or a hearing is requested, EPA will publish a
timely withdrawal in the Federal Register indicating which provisions
will become effective, and which provisions are being withdrawn due to
adverse comment.

Comments. We are publishing the direct final rule amendments
without prior proposal because we view the amendments as
noncontroversial and do not anticipate adverse comments. However, in
the Proposed Rules section of this Federal Register, we are publishing
a separate document that will serve as the proposal in the event that
timely adverse comments are received. If we receive such adverse
comments on the amendments, we will publish a timely withdrawal in the
Federal Register informing the public which provisions will become
effective and which provisions are being withdrawn due to adverse
comment. We will address all public comments in a subsequent final rule
based on the proposed rule. Any of the distinct amendments in the
direct final rule for which we do not receive adverse comment will
become effective on the date set out above. We will not institute a
second comment period on the direct final rule amendments. Any parties
interested in commenting must do so at this time.
Judicial Review. Under section 307(b)(1) of the CAA, judicial
review of the direct final rule amendments is available only by filing
a petition for review in the U.S. Court of Appeals for the District of
Columbia by August 30, 2005. Under section 307(d)(7)(B) of the CAA,
only an objection to the direct final rule amendments that was raised
with reasonable specificity during the period for public comment can be
raised during judicial review. Moreover, under section 307(b)(2) of the
CAA, the requirements established by the direct final rule amendments
may not be challenged separately in any civil or criminal proceedings
brought by EPA to enforce these requirements.

I. Why Are We Amending the Rule?

On November 10, 2003, we promulgated NESHAP for Miscellaneous
Organic Chemical Manufacturing as subpart FFFF in 40 CFR part 63 (68 FR
63852). Since promulgation of the NESHAP, we determined that the
alternative standard, which limits the outlet concentration to 20 parts
per million, did not contain several provisions that have been included
in the same alternative standard in other rules, that the flare
provisions are not consistent with other rules, that the procedures to
account for dilution air added to vent streams before a combustion
device are unnecessarily restrictive, and that the vapor balancing
alternative for storage tanks could be extended to vapor balancing to
barges.

II. What Amendments Are We Making to the Rule?

Amendments to the Procedure for Correcting Measured Concentrations
to Account for Supplemental Gases. If you comply with an outlet
concentration emission limit and use a combustion device, the NESHAP
require you to correct the measured outlet concentration to 3 percent
oxygen to account for dilution caused by adding supplemental gases to
the emission stream prior to the control device. The direct final rule
amendments add a second option that allows you to correct only for the
actual amount of supplemental gas. This option is consistent with the
correction requirement in the final rule for noncombustion devices.
The correction to 3 percent oxygen was originally used in new
source performance standards for air oxidation unit processes,
distillation operations, and reactor processes in the synthetic organic
chemical manufacturing industry (40 CFR part 60, subparts III, NNN and
RRR). The value of 3 percent represents good engineering practice when
oxygen-deficient streams are combusted with supplemental combustion air
(i.e., a supplemental gas). To prevent owners or operators from
diluting streams to meet the outlet concentration emission limit for
noncombustion devices, the NESHAP require correction of the actual
flowrate of supplemental gases. The direct final rule amends 40 CFR
63.2450(i) to allow a correction based on the actual flowrate of
supplemental gases, as well as the correction to 3 percent oxygen for
combustion devices if supplemental gases are used as allowed by the
NESHAP. In addition, the direct final rule amends the definition of
supplemental gas to mirror the definition of supplemental combustion
air in 40 CFR 63.1312, which is appropriate for both combustion and
noncumbustion devices.
Clarification of the Initial Compliance Requirements for Flares.
The direct final rule clarifies the initial compliance requirements for
flares because we understand the promulgated language has caused some
confusion. If you use a flare to comply with an emission limit, the
NESHAP specify that you must comply with the requirements in 40 CFR
63.982(b), which in turn, references 40 CFR 63.987. These are the only
compliance requirements that apply to flares, including flares used to
control batch process vents. Thus, the procedures in Sec.
63.2460(c)(2)(i) of the NESHAP to demonstrate compliance with a percent
reduction emission limit by comparing the uncontrolled and controlled
emission limits apply only if you use a non-flare control device. You
never have to demonstrate the percent reduction for a flare; you only
have to meet the requirements in 40 CFR 63.987. The direct final rule
adds a sentence to 40 CFR 63.2460(c)(2)(i) to clarify this point.
The requirement in 40 CFR 63.2460(c)(2)(ii) to establish emission
profiles before conducting a performance test or design evaluation for
a control device that controls emissions from batch process vents also
applies when you use a non-flare control device. The direct final rule

[[Page 38556]]

revises 40 CFR 63.2460(c)(2)(ii) to clarify this point.
Amendments to the Initial Compliance Requirements for Flares Used
to Control Batch Process Vents. The direct final rule adds a new
paragraph (b)(4)(iii) to 40 CFR 63.2460 to specify that you may
designate emission streams that are controlled with a flare as Group 1.
By meeting the requirements in 40 CFR 63.987, the owner or operator
demonstrates compliance with the HAP destruction requirements in the
NESHAP.
Amendments to Performance Testing for Demonstrating Initial
Compliance with a Percent Reduction Requirement. Section 63.2450(d)
through (f) of the NESHAP specify that you must comply with various
requirements of 40 CFR part 63, subpart SS, for performance testing
provisions. One exception is that the option in 40 CFR 63.997(e)(2)(iv)
to demonstrate compliance with a percent reduction emission limit by
measuring total organic compounds (TOC) was prohibited by 40 CFR
63.2450(n) of the NESHAP. Since promulgation, we have determined that
this restriction is unwarranted because 40 CFR 63.997(e)(2)(iv)(G) and
(H) describe procedures for using Methods 25 and 25A of 40 CFR part 60,
appendix A, for measuring TOC. The direct final rule removes 40 CFR
63.2450(n) to allow compliance with a percent reduction limit to be
demonstrated by measuring either total organic HAP or TOC as specified
in 40 CFR 63.997(e)(2)(iv).
Amendments to the Alternative Standard. The direct final rule
amendments add additional options for the monitoring provisions to the
alternative standard and adds planned routine maintenance provisions
for storage tanks. The direct final rule amendments also permit
compliance with the emission limits and work practice standards in
Tables 1 through 4 to subpart FFFF of part 63 to be met by limiting the
outlet concentration and demonstrating compliance with the outlet
concentration emission limit through continuous emission monitoring.
The direct final rule amendments allow monitoring of operating
parameters as an alternative to adjusting measured concentrations to
account for dilution caused by supplemental gases, indicate that the
planned routine maintenance provisions apply under the alternative
standard for control devices that are used to control emissions from
storage tanks, and clarify a couple of references.
The introductory text in 40 CFR 63.2505(b) of the NESHAP currently
requires you to meet the requirements specified in 40 CFR
63.1258(b)(5)(i) to demonstrate compliance with the alternative
standard. This reference inadvertently excludes the options in 40 CFR
63.1258(b)(5)(ii) for monitoring operating parameters as an alternative
to adjusting the measured concentrations to account for the dilution
caused by adding supplemental gases to the emission stream prior to the
control device. For combustion devices, the option requires operation
above minimum temperature and residence time limits and monitoring to
demonstrate continuous compliance with the limits. For noncombustion
devices used to control emissions from dense gas systems (i.e., systems
with oxygen levels less than 12 percent), the option requires
calculation of a flowrate setpoint and monitoring of the flowrate to
demonstrate continuous compliance with the setpoint. These options are
as valid for miscellaneous organic chemical manufacturing sources as
for pharmaceuticals production sources. The preamble to the proposed
amendments to the NESHAP for pharmaceuticals production describes the
rationale for these alternatives (65 FR 19152, April 10, 2000). As
detailed therein, available data indicate that a properly designed and
operated combustion device will reduce emissions by 98 percent if it
maintains the specified residence time and temperature. With respect to
dense gas systems, the flowrate setpoint calculated for dense gas
systems is an indicator of HAP concentration in the gas stream into the
control device, and maintaining the flowrate below this value would
demonstrate that significant dilution is not occurring. Therefore, the
direct final rule amendments modify the introductory text in Sec.
63.2505(b) to reference all of the provisions in Sec. 63.1258(b)(5).
The direct final rule amendments also add language specifying that
the alternative standard does not apply to emissions from storage tanks
during periods of planned routine maintenance of the control device.
All of this language is identical to the planned routine maintenance
language in 40 CFR 63.2470 that applies if you comply with the percent
reduction emission limit. The exemption was included for compliance
with the percent reduction emission limit because the storage tank
cannot necessarily be shutdown while the control device is shutdown for
maintenance. The same rationale applies for the alternative standard.
Section 63.2505(b)(5)(ii) in the NESHAP specifies requirements for
continuous parameter monitoring systems (CPMS) for scrubbers used to
comply with the option to reduce hydrogen halide and halogen HAP
emissions after a combustion device by 95 percent. The current language
specifies that you must install, operate, and maintain CPMS for the
scrubber as specified in 40 CFR 63.2450(k). Since the actual
requirements are in 40 CFR 63.994(c), which is modified by Sec.
63.2450(k), the direct final rule amendments revise the provision to
reference both sections. Finally, the direct final rule amendments
reorder two of the paragraphs in Sec. 63.2505(b) to improve readability.
Amendments to the Vapor Balancing Alternative for Storage Tanks.
The direct final rule amendments extend vapor balancing to cover liquid
transfers from barges to storage tanks. The NESHAP allow vapor
balancing from storage tanks to tank trucks and railcars. Since
promulgation of the NESHAP, we have determined that barges are used to
supply materials to storage tanks in the miscellaneous organic chemical
manufacturing industry, and the vapor balancing procedures are as valid
for barges as for tank trucks and railcars. The only difference is that
the testing procedures to determine vapor-tightness of barges are
specified in 40 CFR 61.304(f).
Amendments to the Definition of Group 1 Wastewater. The direct
final rule amendments add a new paragraph (4) to Sec. 63.2485(c) to
specify that effluent from a water scrubber or any other control device
that has been used to comply with an emission limit for process vents
is Group 1 wastewater, provided the process vent emission stream is
Group 1 for HAP listed in Table 8 to 40 CFR part 63, subpart FFFF. This
change is needed to ensure that HAP removed from an emission stream are
destroyed or otherwise treated so that they are not simply re-emitted.
The new language is similar to requirements the NESHAP for
Pharmaceuticals Production.
Amendment to the Definition of Continuous Process Vent. Section
63.2550(i) of the NESHAP defines ``continuous process vent'' using the
same language as in 40 CFR 63.107 of the Hazardous Organic NESHAP
(HON), except that references to other sections in the HON are replaced
by references to provisions in 40 CFR part 63, subpart FFFF. Section
63.107(d) of the HON specifies that a gas stream must contain greater
than 0.005 weight percent total organic HAP to be a continuous process
vent. The direct final rule amendments change ``total organic HAP'' to
``total HAP'' for the purposes of subpart FFFF, to clarify the
applicability of the emission limits for inorganic HAP

[[Page 38557]]

emissions from process vents that are specified in Table 3 to subpart FFFF.
According to the current definition of Continuous process vent in
the NESHAP, if the only HAP in a gas stream is inorganic HAP, then it
would not be a continuous process vent (or any kind of process vent),
even if it meets all of the other criteria specified in 40 CFR 63.107.
This means it also would not be subject to the emission limits for
inorganic HAP in Table 3 to subpart FFFF of part 63. However, in
setting the MACT floor for inorganic HAP emissions, we used all
available data for gas streams from processing operations, not just
data for streams that also had organic HAP. Changing Sec. 63.107(d)
for the purposes of subpart FFFF ensures that such streams from
continuous operations are subject to the emission limits for inorganic
HAP, as we intended. This change also makes the definition for
continuous process vent consistent with the definition for batch
process vent, which already includes a threshold based on total HAP.
Clarification of Notification of Compliance Status Reporting
Requirements. The introductory text in 40 CFR 63.9(h)(2)(i) requires
the owner or operator of an affected source to submit to the
Administrator a notification of compliance status, signed by the
responsible official who shall certify its accuracy. Table 12 to
subpart FFFF of part 63 inadvertently stated that this paragraph does
not apply to subpart FFFF. This was not our intent. We intended to
specify only that the subparagraphs (A) through (G) do not apply
because the types of information to include in the report are specified
in Sec. 63.2520(d) of subpart FFFF rather than Sec. 63.9(h)(2).
Therefore, the direct final rule amendments revise the references in
the entry for Sec. 63.9(h)(1)--(6) in Table 12 to subpart FFFF to
clarify this point.
Miscellaneous Technical Corrections. The direct final rule
amendments include several changes to correct references and drafting
errors.

III. Statutory and Executive Order Reviews

A. Executive Order 12866: Regulatory Planning and Review

Under Executive Order 12866 (58 FR 51735, October 4, 1993), EPA
must determine whether the regulatory action is ``significant'' and,
therefore, subject to Office of Management and Budget (OMB) review and
the requirements of the Executive Order. The Executive Order defines
``significant regulatory action'' as one that is likely to result in a
rule that may:
(1) Have an annual effect on the economy of $100 million or more or
adversely affect in a material way the economy, a sector of the
economy, productivity, competition, jobs, the environment, public
health or safety, or State, local, or tribal governments or communities;
(2) Create a serious inconsistency or otherwise interfere with an
action taken or planned by another agency;
(3) Materially alter the budgetary impact of entitlements, grants,
user fees, or loan programs, or the rights and obligations of
recipients thereof; or
(4) Raise novel legal or policy issues arising out of legal
mandates, the President's priorities, or the principles set forth in
the Executive Order.
It has been determined that the direct final rule amendments are
not a ``significant regulatory action'' under the terms of Executive
Order 12866 and are, therefore, not subject to OMB review.

B. Paperwork Reduction Act

This action does not impose any new information collection burden.
This action gives a source owner or operator several additional
compliance options. Since they are only options, this action will not
increase the information collection burden. The OMB has previously
approved the information collection requirements contained in the
existing regulations under the provisions of the Paperwork Reduction
Act, 44 U.S.C. 3501 et seq., and has assigned OMB control number 2060-
0533 (EPA ICR No. 1969.02).
Copies of the information collection request (ICR) document(s) may
be obtained from Susan Auby, by mail at the Office of Environmental
Information, Collection Strategies Division; U.S. EPA (2822T); 1200
Pennsylvania Ave., NW., Washington, DC 20460, by e-mail at
auby.susan@epa.gov, or by calling (202) 566-1672. A copy may also be
downloaded off the Internet at http://www.epa.gov/icr. Include the ICR
or OMB number in any correspondence.
Burden means the total time, effort, or financial resources
expended by persons to generate, maintain, retain, or disclose or
provide information to or for a Federal agency. This includes the time
needed to review instructions; develop, acquire, install, and utilize
technology and systems for the purposes of collecting, validating, and
verifying information, processing and maintaining information, and
disclosing and providing information; adjust the existing ways to
comply with any previously applicable instructions and requirements;
train personnel to be able to respond to a collection of information;
search data sources; complete and review the collection of information;
and transmit or otherwise disclose the information.
An Agency may not conduct or sponsor, and a person is not required
to respond to a collection of information unless it displays a
currently valid OMB control number. The OMB control numbers for EPA's
regulations are listed in 40 CFR part 9 and 48 CFR chapter 15.

C. Regulatory Flexibility Act

The EPA has determined that it is not necessary to prepare a
regulatory flexibility analysis in connection with the direct final
rule amendments.
For purposes of assessing the impacts of today's direct final rule
amendments on small entities, a small entity is defined as: (1) A small
business as defined by the Small Business Administration's 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; and (3) a small organization
that is any not-for-profit enterprise which is independently owned and
operated and is not dominant in its field.
After considering the economic impacts of today's final rule on
small entities, EPA has concluded that this action will not have a
significant economic impact on a substantial number of small entities.
In determining whether a rule has a significant economic impact on a
substantial number of small entities, the impact of concern is any
significant adverse economic impact on small entities, since the
primary purpose of the regulatory flexibility analyses is to identify
and address regulatory alternatives ``which minimize any significant
economic impact of the proposed rule on small entities.'' 5 U.S.C. 603
and 604. Thus, an agency may conclude that a rule will not have a
significant economic impact on a substantial number of small entities
if the rule relieves regulatory burden, or otherwise has a positive
economic effect on all of the small entities subject to the rule.
The direct final rule amendments add several compliance options
granting greater flexibility to small entities subject to the final
rule that may result in a more efficient use of resources. We have
therefore concluded that today's final rule will relieve regulatory
burden for all affected small entities.

[[Page 38558]]

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 by State, local, and tribal governments, in
the aggregate, or by 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 EPA 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 EPA 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 EPA establishes any regulatory
requirements that may significantly or uniquely affect small
governments, including tribal governments, it must have developed under
section 203 of the UMRA a small government agency plan. The plan must
provide for notifying potentially 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.
The EPA has determined that the direct final rule amendments do not
contain a Federal mandate that may result in expenditures of $100
million or more for State, local, or tribal governments, in the
aggregate, or the private sector in any 1 year. The direct final rule
amendments provide a source owner or operator with additional options
to comply with the standards. Therefore, the direct final rule
amendments are not subject to the requirements of sections 202 and 205
of the UMRA.

E. Executive Order 13132: Federalism

Executive Order 13132 (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.''
The direct 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.
The direct final rule amendments provide a source owner or operator
with another option to comply with the standards and, therefore, impose
no additional burden on sources. Thus, Executive Order 13132 does not
apply to the direct final rule amendments.
In the spirit of Executive Order 13132 and consistent with EPA
policy to promote communications between EPA and State and local
governments, EPA specifically solicits comment on the direct final rule
amendments from State and local officials.

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

Executive Order 13175 (59 FR 22951, 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.'' The direct final rule amendments do
not have tribal implications, as specified in Executive Order 13175.
The direct final rule amendments provide a source owner or operator
with another option to comply with the standards and, therefore, impose
no additional burden on sources. Thus, Executive Order 13175 does not
apply to the direct final rule amendments.
The EPA specifically solicits additional comment on the direct
final rule amendments from tribal officials.

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

Executive Order 13045 (62 FR 19885, April 23, 1997) applies to any
rule that: (1) Is determined to be ``economically significant'' as
defined under Executive Order 12866, and (2) concerns an environmental
health or safety risk that EPA has reason to believe may have a
disproportionate effect on children. If the regulatory action meets
both criteria, EPA must evaluate the environmental health or safety
effects of the planned rule on children, and explain why the planned
regulation is preferable to other potentially effective and reasonably
feasible alternatives considered by EPA.
The EPA interprets Executive Order 13045 as applying only to those
regulatory actions that are based on health or safety risks, such that
the analysis required under section 5-501 of the Executive Order has
the potential to influence the regulation. Today's direct final rule
amendments are not subject to Executive Order 13045 because they are
based on technology performance, not health or safety risks.
Furthermore, the direct final rule amendments have been determined not
to be ``economically significant'' as defined under Executive Order 12866.

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

The direct final rule amendments are not subject to Executive Order
13211 (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 of 1995

Section 12(d) of the National Technology Transfer and Advancement
Act of 1995 (NTTAA), Public Law 104-113, 12(d) (15 U.S.C. 272 note),
directs EPA to use voluntary consensus standards in its regulatory
activities unless to do so would be inconsistent with applicable law or
otherwise impractical. Voluntary consensus standards are technical
standards (e.g., materials specifications, test methods, sampling
procedures, and business practices) that are developed or adopted by
voluntary consensus standards bodies. The NTTAA directs EPA to provide
Congress, through OMB, explanations when the Agency decides not to use
available and applicable voluntary consensus standards.
No new standard requirements are cited in the direct final rule
amendments. Therefore, EPA is not proposing or adopting any voluntary
consensus standards in the direct final rule amendments.

J. 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

[[Page 38559]]

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. The EPA will submit a report containing the direct final rule
and other required information to the U.S. Senate, the U.S. House of
Representatives, and the Comptroller General of the United States prior
to publication of the direct final rule in the Federal Register. The
direct final rule is not a ``major rule'' as defined by 5 U.S.C.
804(2). The direct final rule amendments are effective on August 30, 2005.
