40 CFR Part 63

[FRL-6321-7]
RIN 2060-AH71


National Emission Standards for Hazardous Air Pollutants for 
Source Categories: Amendment for Hazardous Air Pollutants Emissions 
From Magnetic Tape Manufacturing Operations

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The EPA is proposing to amend National Emission Standards for 
Hazardous Air Pollutants (NESHAP) From Magnetic Tape Manufacturing 
Operations, codified as subpart EE to 40 CFR part 63. The existing 
standards allow facility owners or operators to leave a limited number 
of solvent storage tanks uncontrolled if they control coating 
operations at a level greater than the standards otherwise require. EPA 
is publishing this proposed amendment to provide another compliance 
option for facility owners and operators. If facility owners or 
operators increase the control of hazardous air pollutant (HAP) 
emissions from coating operations beyond what the standards otherwise 
require, this final amendment gives them the choice of leaving a 
limited number of solvent storage tanks and/or a limited number of 
pieces of mix preparation equipment uncontrolled. EPA believes this 
proposed amendment will not decrease the stringency of the existing 
standards.
    We don't consider this amendment controversial and expect no 
negative comments, so we're also publishing it as a direct final rule 
in the Final Rules section of this Federal Register publication. We'll 
consider any negative comments about today's direct final rule to also 
be negative comments about this proposal. We'll take no further action 
unless, within the time allowed (see DATES, below), we receive negative 
comments about the proposal or final rule, or we receive a request for 
a public hearing on the proposal. If we take no further action, the 
amendment will become effective on the date in the DATES section of the 
associated direct final rule.

DATES: Comments. The EPA will accept comments regarding the proposed 
amendment on or before May 10, 1999. Additionally, a public hearing 
regarding the proposed amendment will be held if anyone requesting to 
speak at a public hearing contacts the EPA by April 19, 1999. If a 
hearing is requested, the hearing will be held at the EPA Office of 
Administration Auditorium, Research Triangle Park, NC. on April 30, 
1999 beginning at 10:00 a.m.. For more information about submittal of 
comments and requesting a public hearing, see the SUPPLEMENTARY 
INFORMATION section in this preamble.

Determination'
    C. Regulatory Flexibility

    J. National Technology Transfer and Advancement Act

I. Authority

    The statutory authority for this action is provided by sections 
101, 112, 114, 116, and 301 of the Clean Air Act, as amended (42 U.S.C. 
7401, 7412, 7414, 7416, and 7601).

II. Background

    On December 15, 1994, we published in the Federal Register the 
final rule containing national standards for reducing HAP in facilities 
that manufacture magnetic tape (see 59 FR 64580). Since then, a 
regulated facility has asked us to consider alternative compliance 
options for a narrow aspect of the regulation.
    This proposed amendment is very similar to the existing provision 
at 40 CFR 63.703(c)(4) but adds an optional approach for compliance. 
The new approach requires the same enhanced control efficiency for 
coating operations as existing provisions. We expect this proposed 
amendment to protect the environment as well as the rule issued in 1994 
while offering the regulated community more flexibility for compliance.

III. Proposed Amendment

    We're proposing to amend the emission standards for magnetic tape 
manufacturing so facilities will have another compliance option if they 
choose to control their coating operations to an overall HAP reduction 
efficiency greater than 95%. Under the existing standards, facility 
owners or operators may choose to control HAP emissions for all coating 
operations by an overall efficiency of at least 97%, 98%, or 99%, 
instead of controlling 10, 15, or 20 HAP solvent storage tanks, 
respectively. This amendment would allow them to control their coating 
operations to those higher efficiencies in exchange for leaving 
uncontrolled a limited number of pieces of mix preparation equipment, 
combined with a limited number of HAP solvent storage tanks.
    For further information on this proposed amendment and our 
rationale, see the associated direct final rule published in the Final 
Rules section of today's Federal Register. We incorporate all such 
information in this proposal by reference.

IV. Administrative Requirements

A. Public Hearing

    A public hearing will be held, if requested, to provide opportunity 
for interested persons to make verbal presentations regarding this 
regulation in accordance with 42 U.S.C. 7004(b)(1); 40 CFR part 25. 
Persons wishing to make a verbal presentation on this proposed rule 
amendment must contact Michele Aston of the U.S. EPA, at the address 
given in the ADDRESSES section of this document, no later than April 
19, 1999. If a public hearing is held, written statements may be 
submitted at the hearing, and EPA will also include in the record any 
rebuttal or supplementary information submitted in written form within 
30 days following the date of the hearing. Any written statements not 
submitted at the hearing should be sent to EPA at the addresses given 
in the ADDRESSES section of this document. If a public hearing is held, 
a verbatim transcript of the hearing, and written statements provided 
at or following the hearing will be available for inspection and 
copying during normal business hours at the EPA address for docket 
inspection given in the ADDRESSES section of this preamble.

B. Executive Order 12866: ``Significant Regulatory Action 
Determination''

    Under Executive Order 12866 (58 FR 51735, October 4, 1993) the 
Agency 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 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 in 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 entitlement, grants, 
user fees, or loan programs of 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.
    Because the annualized cost of the proposed rule amendment would be 
significantly less than $100 million and would not meet any of the 
other criteria specified in the Executive Order, it has been determined 
that this action is not a ``significant regulatory action'' under the 
terms of Executive Order 12866, and is therefore not subject to OMB 
review.
    Executive Order 12866 also encourages agencies to provide a 
meaningful public comment period, and suggests that in most cases the 
comment period should be 60 days. However, in consideration of the very 
limited scope of this amendment, the EPA considers 30 days to be 
sufficient in providing a meaningful public comment period for this 
regulatory action.

C. Regulatory Flexibility

    The Regulatory Flexibility Act (RFA) generally requires an agency 
to conduct a regulatory flexibility analysis of any rule subject to 
notice and comment rulemaking requirements 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 not-for-profit enterprises, and small governmental 
jurisdictions. The EPA determined that this amendment to the Magnetic 
Tape Manufacturing Operations does not have a significant impact on a 
substantial number of small entities. EPA certifies that this action 
will not have a significant economic impact on a substantial number of 
small entities.

D. Paperwork Reduction Act

    This amendment does not include or create any information 
collection activities subject to the Paperwork Reduction Act, and 
therefore no information collection request (ICR) will be submitted to 
OMB for review in

[[Page 17467]]

compliance with the Paperwork Reduction Act, 44 U.S.C. 3501, et seq.

E. 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 
one 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 of 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, 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.
    As noted above, this proposed amendment is of very narrow scope, 
and provides a compliance alternative very similar to one already 
available in the promulgated regulation. The EPA has determined that 
this action contains no regulatory requirements that might 
significantly or uniquely affect small governments. EPA has also 
determined that this action does 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. Thus, today's action is not subject to the requirements of 
sections 202 and 205 of the UMRA.

F. Docket

    The docket is an organized and complete file of the administrative 
record upon which any final rule is based. The docketing system is 
intended to allow members of the public and industries involved to 
readily identify and locate documents so that they can effectively 
participate in the rulemaking process. All written comments on this 
proposal submitted in a timely manner will be included in the docket. 
Along with the proposed and promulgated standards and their preambles, 
the contents of the docket, except for certain interagency documents, 
will serve as the record for judicial review. (See CAA section 
307(d)(7)(A).)

G. Executive Order 12875: Enhancing the Intergovernmental Partnership

    Under Executive Order 12875, the EPA may not issue a regulation 
that is not required by statute and that creates a mandate upon a 
State, local or tribal government, unless the Federal government 
provides the funds necessary to pay the direct compliance costs 
incurred by those governments, or EPA consults with those governments. 
If EPA complies by consulting, Executive Order 12875 requires EPA to 
provide to the Office of Management and Budget a description of the 
extent of the EPA's prior consultation with representatives of affected 
State, local and tribal governments, the nature of their concerns, 
copies of any written communications from the governments, and a 
statement supporting the need to issue the regulation. In addition, 
Executive Order 12875 requires the EPA to develop an effective process 
permitting elected officials and other representatives of State, local 
and tribal governments ``to provide meaningful and timely input in the 
development of regulatory proposals containing significant unfunded 
mandates.''
    Today's action does not create a mandate on State, local or tribal 
governments. The amendments to the rule do not impose any new or 
additional enforceable duties on these entities. Accordingly, the 
requirements of section 1(a) of Executive Order 12875 do not apply to 
this action.

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

    Executive Order 13045 applies to any rule that the EPA determines 
(1) economically significant as defined under E.O. 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, the Agency 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 the Agency.
    This amendment to the National Emissions Standards for Magnetic 
Tape Manufacturing Operations is not subject to E.O. 13045, entitled 
Protection of Children from Environmental Health Risks and Safety Risks 
(62 FR 19885, April 23, 1997), because it is not an economically 
significant regulatory action as defined by E.O. 12866, and it does not 
address an environmental health or safety risk that would have a 
disproportionate effect on children.

I. Executive Order 13084: Consultation and Coordination With Indian 
Tribal Governments

    Under Executive Order 13084, the EPA 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 costs incurred by the tribal governments, or EPA consults 
with those governments. If EPA complies by consulting, Executive Order 
13084 requires EPA to provide to the Office of Management and Budget, 
in a separate identified section of the preamble to the rule, a 
description of the extent of the EPA's 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, Executive Order 13084 requires the EPA 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 amendments do not significantly or uniquely affect the 
communities of Indian tribal government. The amendments to the rule do 
not impose any new or additional enforceable duties on these entities. 
Accordingly, the requirements of section 3(b) of Executive Order 13084 
do not apply to this action.

[[Page 17468]]

J. National Technology Transfer and Advancement Act

    Under section 12(d) of the National Technology Transfer and 
Advancement Act (NTTA), Public Law 104-113 (March 7, 1996), the EPA is 
required to use voluntary consensus standards in its regulatory and 
procurement 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, business practices, etc.) which are adopted by 
voluntary consensus standard bodies. Where available and potentially 
applicable voluntary consensus standards are not used by the EPA, the 
NTTA requires the Agency to provide Congress, through OMB, an 
explanation of the reasons for not using such standards. This amendment 
does not put forth any technical standards; therefore, consideration of 
voluntary consensus standards was not required.
