National Emission Standards for Hazardous Air Pollutants: Generic
Maximum Achievable Control Technology (Generic MACT)
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule; corrections.
-----------------------------------------------------------------------
SUMMARY: On June 29, 1999, we issued the National Emission Standards
for Hazardous Air Pollutants: Generic Maximum Achievable Control
Technology (Generic MACT) (64 FR 34854). This final rule corrections
serve to clarify and correct errors in the promulgated rule.
EFFECTIVE DATE: November 22, 1999.
FOR FURTHER INFORMATION CONTACT: For information concerning these
corrections amendments, contact David W. Markwordt, Policy, Planning,
and Standards Group, Emission Standards Division (MD-13), U.S.

electronic mail address: markwordt.david@epa.gov.
SUPPLEMENTARY INFORMATION: Regulated entities. Entities that will
potentially be affected by these corrections are those that produce
acetal resins, acrylic and modacrylic fiber, hydrogen fluoride, and
polycarbonate and are major sources of hazardous air pollutants as
defined in section 112 of the Clean Air Act (Act). The regulated
categories and entities include the following:
------------------------------------------------------------------------
Category Regulated entities a
------------------------------------------------------------------------
Industry..................... Producers of homopolymers and/or
copolymers of alternating oxymethylene
units.
Producers of either acrylic fiber or
modacrylic fiber synthetics composed of
acrylonitrile (AN) units.
Producers of, and recoverers of HF by
reacting calcium fluoride with sulfuric
acid. For the purpose of implementing
the rule, HF production is not a process
that produces gaseous HF for direct
reaction with hydrated aluminum to form
aluminum fluoride (i.e., the HF is not
recovered as an intermediate or final
product prior to reacting with the
hydrated aluminum).
Producers of polycarbonate.
------------------------------------------------------------------------
a This table is not intended to be exhaustive, but rather provides a
guide for readers regarding entities likely to be regulated by this
action. This table lists the types of entities that we are now aware
could potentially be regulated by this action. Other types of entities
not listed in the table could also be regulated. To determine whether
your facility, company, business, organization, etc., is regulated by
this action, you should carefully examine the applicability criteria
in Sec. 63.1104(a)(1), (b)(1), (c)(1), and (d)(1) of the rule. If you
have questions regarding the applicability of this action to a
particular entity, consult the person listed in the preceding FOR
FURTHER INFORMATION CONTACT section.
I. What Is the Background for the Corrections?
On June 29, 1999 (64 FR 34854), we published the National Emission
Standards for Hazardous Air Pollutants: Generic MACT final rule which
promulgated standards for four major HAP source categories (i.e.,
acetal resins production, acrylic and modacrylic fiber production,
hydrogen fluoride production, and polycarbonate production). The
proposal for the Generic MACT rule was published on October 14, 1998
(63 FR 55178), and given the size of the proposed rule, we allowed for
a 90-day public comment period even though we were under a May 15, 1999
court ordered deadline for the Administrator's signature of the final
rule. Because of the short time period between proposal and
promulgation and the many changes made to the proposal package, some
inadvertent errors were made. Today's action consists of editorial,
cross-reference, and clarifying corrections to the promulgated Generic
MACT rule published on June 29, 1999 (64 FR 34854). These corrections
will become effective immediately (without further rulemaking action)
on November 22, 1999. We have determined that it is unnecessary to
provide prior notice and opportunity to comment on these corrections.
In one case, we determined an opportunity for public comment is
warranted; we are proposing amendments to address this case in a
separate notice.
Today's action corrects typographical, grammatical, and cross-
reference errors. For example, as promulgated,
Sec. 63.998(a)(1)(iii)(A) incorrectly referred the reader to
Sec. 63.999(c)(8) for the requirement for an owner or operator to
report times and duration of all periods during which the flare or all
the pilot flames are absent. The correct citation for this requirement
is Sec. 63.999(c)(3) and today's action makes the necessary changes to
reflect the accurate citation. For another example, Sec. 63.1012(f)
incorrectly includes a citation with two repetitive paragraph
designations (i.e., Sec. 63.1003(e)(e)). Today's action corrects that
error by removing one of those paragraph designations (i.e.,
Sec. 63.1003(e)).
One of the corrections is in wording. We made an error in Table 2
to Sec. 63.1103(b)(3)(i), item 4, that could result in control
applicability errors. At promulgation, Table 2 to
Sec. 63.1103(b)(3)(i), item 4, erroneously required that an owner or
operator of a new or modified source that met specified criteria would
be subject to new source requirements. We should have specified that an
owner or operator of a new or reconstructed source, not modified
source, that met specified criteria would be subject to new source
requirements. We have corrected this error by replacing the word
``modified'' with ``reconstructed.''
II. What Are the Impacts Associated With the Corrections?
This action consists of corrections and clarifications of our
intent at the time of
[[Page 63703]]
promulgation of 40 CFR part 63, subparts SS, TT, UU, WW, and YY, and
will not affect the estimated emissions reduction or the control costs
for the standards promulgated for AR, AMF, HF, and PC production source
categories on June 29, 1999 (64 FR 34854). These clarifications and
corrections should make it easier for owners and operators of affected
sources, and for local and State authorities, to understand and
implement the requirements found in these subparts.
III. Administrative Requirements
A. Paperwork Reduction Act
The information collection requirements in this rule were submitted
for approval to the Office of Management and Budget (OMB) under the
Paperwork Reduction Act, 44 U.S.C. 3501, et seq. We submitted an
Information Collection Request (ICR) document (ICR No. 1871.02) and a
copy may be obtained from Sandy Farmer, OPPE Regulatory Information
Division, U.S. Environmental Protection Agency (2137), 401 M Street,
SW, Washington, DC 20460 or by calling (202) 260-2740. We 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 approved the information collection
requirements under the Generic MACT rule for the AR, AMF, HF, and PC
production source categories and assigned the OMB control number 2060-
0420 to the ICR. This approval expires September 30, 2002.
These corrections will not impact the information collection
estimates made previously for the Generic MACT consolidated rulemaking
package. Therefore, the ICR has not been revised.
B. Executive Order 12866
Under Executive Order 12866 (58 FR 51735, October 4, 1993), we must
determine whether the regulatory action is ``significant'' and
therefore subject to review by OMB and the requirements of the
Executive Order. The 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.
Pursuant to the terms of Executive Order 12866, we have determined
that these correcting amendments do not qualify as a ``significant
regulatory action'' and, therefore, are not subject to review by OMB.
C. 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.'' Under
Executive Order 13132, EPA may not issue a regulation that has
federalism implications, that imposes substantial direct compliance
costs, and that is not required by statute, unless the Federal
government provides the funds necessary to pay the direct compliance
costs incurred by State and local governments, or EPA consults with
State and local officials early in the process of developing the
proposed regulation. EPA also may not issue a regulation that has
federalism implications and that preempts State law unless the Agency
consults with State and local officials early in the process of
developing the proposed regulation.
If EPA complies by consulting, Executive Order 13132 requires EPA
to provide to the Office of Management and Budget (OMB), in a
separately identified section of the preamble to the rule, a federalism
summary impact statement (FSIS). The FSIS must include a description of
the extent of EPA's prior consultation with State and local officials,
a summary of the nature of their concerns and the agency's position
supporting the need to issue the regulation, and a statement of the
extent to which the concerns of State and local officials have been
met. Also, when EPA transmits a draft final rule with federalism
implications to OMB for review pursuant to Executive Order 12866, EPA
must include a certification from the agency's Federalism Official
stating that EPA has met the requirements of Executive Order 13132 in a
meaningful and timely manner.
This final rule 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.
This rule has minimal direct affects on the 10 plants which are
impacted by this rule. This rule has even less impacts on States within
which the plants reside. Thus, the requirements of section 6 of the
Executive Order do not apply to this rule.
D. Regulatory Flexibility Act/Small Business Regulatory Enforcement
Fairness Act of 1996
The Regulatory Flexibility Act (RFA) of 1980 (5 U.S.C. 601, et
seq.), as amended by the Small Business Regulatory Enforcement Fairness
Act of 1996 (SBREFA), requires the EPA to give special consideration to
the effect of Federal regulations on small entities and to consider
regulatory options that might mitigate any such impacts. Small entities
include small businesses, small not-for-profit enterprises, and small
governmental jurisdictions.
Today's corrections will not have a significant impact on a
substantial number of small entities because they clarify and make
corrections to the promulgated 40 CFR part 63, subparts SS, TT, UU, WW
and YY, and do not impose any additional regulatory requirements on
owners or operators of affected sources regulated by standards
promulgated on June 29, 1999 (64 FR 34854).
E. Unfunded Mandates Reform Act
Under section 202 of the Unfunded Mandates Reform Act (UMRA) of
1995, Pub. L. 104-4, we 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 in any 1 year. Section 203 requires us to establish a
plan for obtaining input from and informing, educating, and advising
any small governments that may be significantly or uniquely affected by
the rule.
Under section 205 of UMRA, we must identify and consider a
reasonable number of regulatory alternatives before promulgating a rule
for which a budgetary impact statement must be
[[Page 63704]]
prepared. The Agency must select the least burdensome alternative from
those alternatives for State, local, and tribal governments and the
private sector that achieves the objectives of the rule, unless the
Agency explains why this alternative is not selected or unless the
selection of this alternative is inconsistent with law.
Because these corrections do not include 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 1
year, we have not prepared a budgetary impact statement or specifically
addressed the selection of the least costly, most cost-effective, or
least burdensome alternative. In addition, because small governments
will not be significantly or uniquely affected by these correcting
amendments, we are not required to develop a plan with regard to small
governments. Therefore, the requirements of UMRA do not apply to this
action.
G. Congressional Review Act
The Congressional Review Act, 5 U.S.C. 801, et seq., as added by
the SBREFA of 1996, provides that before a rule may take effect, the
agency promulgating the rule must submit a rule report, which includes
a copy of the corrections, to each House of the Congress and to the
Comptroller General of the United States. Therefore, we will submit a
report containing these corrections 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
in the Federal Register. A major rule cannot take effect until 60 days
after it is published in the Federal Register. This action does not
constitute a ``major rule'' as defined by 5 U.S.C. 804(2).
H. National Technology Transfer and Advancement Act
Under section 12(d) of the National Technology Transfer and
Advancement Act of 1995 (NTTAA), Pub. L. 104-113, section 12(d) (15
U.S.C. 272 note), we are directed to use voluntary consensus standards
instead of government-unique standards in its regulatory activities
unless to do so would be inconsistent with applicable law or otherwise
impractical. By doing so, the Act is intended to reduce the cost to the
private and public sectors.
Voluntary consensus standards are technical standards (e.g.,
materials specifications, test methods, sampling procedures, etc.) that
are developed or adopted by one or more voluntary consensus standards
bodies. Examples of organizations generally regarded as voluntary
consensus standards bodies include the American Society for Testing and
Materials (ASTM), International Organization for Standardization (IOS),
International Electrotechnical Commission (IEC), American Petroleum
Institute (API), National Fire Protection Association (NFPA), and the
Society of Automotive Engineers (SAE). The NTTAA requires that we
provide Congress, through OMB, explanations when we decide not to use
available and applicable voluntary consensus standards.
As part of a larger effort, we are undertaking a project to cross-
reference existing voluntary consensus standards in testing, sampling,
and analysis, with current and future EPA test methods. When completed,
this project will assist us in identifying potentially applicable
voluntary consensus standards that can then be evaluated for
equivalency and applicability in determining compliance with future
regulations.
This action does not require the use of any new technical
standards, therefore section 12(d) does not apply.
I. Executive Order 13045
Executive Order 13045, entitled Protection of Children from
Environmental Health Risks and Safety Risks (62 FR 19885, April 23,
1997), applies to any rule that we determine (1) is economically
significant as defined under Executive Order 12866, and (2) the
environmental health or safety risk addressed by the rule has a
disproportionate effect on children. If the regulatory action meets
both criteria, we 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 us.
These corrections are not subject to Executive Order 13045 because
they do not constitute an economically significant regulatory action as
defined by Executive Order 12866 and because they do not establish an
environmental standard intended to mitigate health or safety risks.
J. Executive Order 13084
Under Executive Order 13084, we may not issue a regulation that is
not required by statute, that significantly or uniquely affects the
communities of Indian tribal governments, and that imposes substantial
direct compliance costs on those communities, unless the Federal
Government provides the funds necessary to pay the direct compliance
cost incurred by the tribal governments, or we consult with those
governments. Under Executive Order 13084, if we comply by consulting,
we are required to provide to OMB, in a separately identified section
of the preamble to the rule, a description of the extent of our prior
consultation with representatives of affected tribal governments, a
summary of the nature of their concerns, and a statement supporting the
need to issue the regulation. In addition, we are required to develop
an effective process permitting elected officials and other
representatives of Indian tribal governments ``to provide meaningful
and timely input in the development of regulatory policies on matters
that significantly or uniquely affect their communities.''
Today's corrections do not impose any duties or compliance costs on
Indian tribal governments. Further, the corrections provided herein do
not significantly alter the control standards imposed by subparts SS,
TT, UU, WW, and YY, including any that may affect communities of Indian
tribal governments. Hence, today's action does not significantly or
uniquely affect the communities of Indian tribal governments.
Accordingly, the requirements of section 3(b) of Executive Order 13084
do not apply to this action.

a Combined vent streams shall use the applicability determination
procedures and methods for process vents from continuous unit
operations (Sec. 63.1104).
b The TRE equation coefficients for halogenated streams (table 7 of this
subpart) shall be used to calculate the TRE index value.
c The TRE is determined according to the procedures specified in Sec.
63.1104(j). If a dryer is manifolded with such vents, and the vent is
routed to a recovery, recapture, or combustion device, then the TRE
index value for the vent must be calculated based on the properties of
the vent stream (including the contributions of the dryer). If a dryer
is manifolded with other vents and not routed to a recovery,
recapture, or combustion device, then the TRE index value must be
calculated excluding the contributions of the dryer. The TRE index
value for the dryer must be calculated separately in this case.
d The mass emission rate of halogen atoms contained in organic compounds
is determined according to the procedures specified in Sec.
63.1104(i).
e The weight-percent organic HAP is determined for equipment according
to procedures specified in Sec. 63.1107.
