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: Direct final rule.

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

SUMMARY: The EPA is taking direct final action 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 final 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 
final amendment will not decrease the stringency of the existing 
standards.

DATES: Effective Date. This final rule amendment is effective on June 
8, 1999 without further notice, unless EPA receives adverse comments on 
this rulemaking by May 10, 1999 or a request for a hearing concerning 
the accompanying proposed rule is received by EPA by April 19, 1999. If 
EPA receives timely adverse comment or a timely hearing request, EPA 
will publish a withdrawal in the Federal Register informing the public 
that this direct final rule will not take effect.

ADDRESSES: Comments. Interested parties may submit comments on this 
rulemaking in writing (original and two copies, if possible) to Docket 
No. A-91-31 to the following address: Air and Radiation Docket and 
Information Center (6102), US Environmental Protection Agency, 401 M 
Street, S.W., Room 1500, Washington, D.C. 20460. Public comments on 
this rulemaking will be accepted until May 10, 1999.
    Docket. A docket containing supporting information used in 
developing this direct final rule amendment is available for public 
inspection and copying at the EPA's docket office located at the above 
address in Room M-1500, Waterside Mall (ground floor). The public is 
encouraged to phone in advance to review docket materials. Appointments

SUPPLEMENTARY INFORMATION: We are publishing this rule amendment 
without prior proposal because we consider this to be a 
noncontroversial amendment, and we do not expect to receive any adverse 
comment. We believe that this change to the previously promulgated rule 
will increase compliance flexibility for affected sources without any 
adverse environmental consequences. However, in the ``Proposed Rules'' 
section of this Federal Register publication, we are publishing a 
separate document that will serve as the proposal for this amendment, 
in the event we receive adverse comment or a hearing request and this 
direct final rule is subsequently withdrawn. This final rule amendment 
will be effective on June 8, 1999 without further notice, unless we 
receive adverse comment on this rulemaking by May 10, 1999 or a request 
for a hearing concerning the accompanying proposed rule is received by 
EPA by April 19, 1999. If EPA receives timely adverse comment or a 
timely hearing request, we will publish a withdrawal in the Federal 
Register informing the public that this direct final rule will not take 
effect. In that event, we will address all public comments in a 
subsequent final rule, based on the proposed rule amendment published 
in the ``Proposed Rules'' section of this Federal Register document. 
The EPA will not provide further opportunity for public comment on this 
action. Any parties interested in commenting on this amendment must do 
so at this time.

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 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 required by the provisions published in 1994. We expect 
this amendment to protect the environment as well as the rule published 
in 1994, while offering the regulated community more flexibility for 
compliance.

III. Regulatory Requirements and Performance Standards

A. Original Compliance Option for Solvent Storage tanks

    In the final rule published in 1994, we included a compliance 
option for owners or operators of facilities that manufacture magnetic 
tape (referred to as operators in the rest of this preamble). It allows 
them to leave uncontrolled the emissions from certain solvent storage 
tanks in return for better controlling the largest emissions source at 
their facilities. Through that alternative compliance provision, we 
allow operators to vent emissions from these tanks to the atmosphere, 
rather than routing them through a control device. (See 40 CFR 
63.703(c)(4)--as published December 15, 1994--for this option.) As 
explained in the 1994 preamble, we concluded then that added control at 
the coating operations would offset emissions from the uncontrolled 
storage tanks (see 59 FR 64590-64592, December 15, 1994.)

B. What Information We Used To Establish the New Compliance Option

    Since 1994, we've received detailed technical information from a 
facility that manufactures magnetic tape (see Docket No. A-91-31). It 
compares estimates for HAP emissions from uncontrolled solvent storage 
tanks to those for uncontrolled pieces of mix preparation equipment. 
The facility asked us to allow more flexibility in the types of 
equipment that can be left uncontrolled in exchange for a higher level 
of control of the coating operations at the facility. In evaluating 
this request, we've generally compared the amount of HAP emissions that 
may be uncontrolled under the 1994 published rule's alternative 
provision with those HAP emissions that may be uncontrolled under the 
added options in today's rule. For this analysis, we incorporate by 
reference our rationale for the existing alternative compliance options 
which was included in our preamble for the 1994 published rule.
    At magnetic tape manufacturing facilities, solvent storage tanks 
and mix preparation equipment are typically covered, even if the 
headspace vapors aren't vented to a control device. Emissions from a 
given solvent storage tank at a manufacturing facility vary depending 
on throughput, tank size, solvents stored in the tanks, and other 
factors. Emissions from a given piece of mix preparation equipment vary 
for similar reasons, and also vary based on the amount that the 
temperature of the mix increases during mixing.
    The facility's detailed technical information estimates their 
maximum potential emissions under process constraints in the milling 
operations. The facility's solvent storage tanks and mix preparation 
equipment have varying characteristics, including capacity. Their 
largest tanks and mix preparation equipement are 20,000 gallons and 
1200 gallons, respectively. The solvent storage tanks have fixed roofs 
with conservation vents, so the facility used standard calculations for 
these tanks to estimate emissions. For solvent recovery tanks, they 
believed this method may not be appropriate because they maintain most 
tanks at nearly constant levels with a mechanical weir. However, we 
don't know of a better way to calculate emissions for these tanks, so 
we'd use the same method unless rigorous monitoring ensured a constant 
level of liquid in the tank. Therefore, we decided to include tanks 
from the solvent recovery unit in our evaluation of the data.
    The facility estimated emissions for their mix preparation 
equipment using our calculation methods for batch processes, which we 
believe is appropriate for this application. In developing the 
regulations, we estimated emissions from the entire mix preparation 
operation. But their method estimates emissions for pieces of mix 
equipment, which requires more detailed information than we had while 
developing the regulations. At the same time, we believe this 
facility's solvent storage tanks and mix preparation equipment are 
representative of the tanks and equipment used by the rest of the 
regulated magnetic tape industry, so we used their data to analyze the 
requested alternative compliance approach.

C. Why We Chose To Allow the New Compliance Option

    The 1994 published rule restricts the capacity of the solvent 
storage tanks we allowed to be uncontrolled to 20,000 gallons each but 
doesn't restrict other parameters that affect emissions. Therefore, we 
believe it's reasonable to use the highest emitting tanks in this 
comparison if they don't exceed the capacity restriction. For the 
magnetic tape manufacturing facility we studied, we found the maximum 
potential HAP emissions from a solvent storage tank and from a piece of 
mix preparation

[[Page 17462]]

equipment were 1.6 tons/yr (tpy) and 1.9 tpy, respectively.
    Because maximum emissions are similar, we believe it's reasonable 
for facility operators to leave uncontrolled some mix preparation 
equipment and some solvent storage tanks, if they better control their 
coating operations. But they must leave fewer pieces of mix preparation 
equipment uncontrolled because the maximum emissions from mix 
preparation equipment are greater than those from solvent storage 
tanks. Also, some tanks had emissions as low as 0.01 tpy, whereas the 
lowest level for mix preparation equipment was 0.1 tpy. Based on all 
the data, it's reasonable to allow manufacturers to leave uncontrolled 
half as many pieces of mix preparation equipment as of solvent storage 
tanks. This 2-to-1 ratio makes up for the wider range of HAP emissions 
in the tanks.
    As noted above, the 1994 published rule's alternative compliance 
approach limits the capacity of solvent storage tanks that can be left 
uncontrolled. Our amendment also uses a capacity limit of 1,200 gallons 
for each piece of mix preparation equipment that can be left 
uncontrolled. We believe the equipment at this facility is 
representative of equipment in the industry. In any case, limiting 
maximum capacity makes sure the size of uncontrolled mix preparation 
equipment is no larger than the size used for the estimates supporting 
this amendment.

D. How the New Compliance Option Affects You as a Manufacturer

    Today's final rule amendment affects you if, as a facility owner or 
operator, you choose to increase the overall control efficiency of your 
coating operations for magnetic tape. As the final rule was published 
in 1994, 40 CFR 63.703(c) allowed you to leave HAP solvent storage 
tanks uncontrolled if you increase the overall control efficiency of 
your coating operations. Under today's final rule amendment, you may 
still leave uncontrolled 10, 15, or 20 tanks in exchange for 
controlling your coating operations to an overall efficiency of 97, 98, 
or 99 percent, respectively. Under today's amendment, however, you may 
leave uncontrolled one piece of mix preparation equipment in exchange 
for two solvent storage tanks left uncontrolled under the 1994 rule. 
For example, you could leave uncontrolled six solvent storage tanks and 
two pieces of mix preparation equipment if you achieve an overall 
efficiency of 97 percent--instead of 10 solvent storage tanks. See the 
amendment to 40 CFR 63.703(c)(4) for combinations you may use to comply 
with the new alternative provisions.
    We believe this amendment will limit HAP emissions from facilities 
that manufacture magnetic tape at least as much as provisions in the 
1994 rule. Furthermore, the amendment will give you more flexibility to 
meet the regulation. We don't expect our amendment to pose any problems 
for enforcement or permitting because it's essentially similar to the 
1994 rule, which affected facilities are following now. We expect 
you'll like this amendment because you may be able to save money and 
other resources, compared to the compliance approaches under the 1994 
rule. Also, if you decide not to follow the amended provisions, they 
won't burden you--they merely give you another option, and the 
regulation is otherwise virtually unchanged.

IV. Administrative Requirements

A. 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 this final 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 
rulemaking.

B. 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. The EPA has also determined that 
is not necessary to prepare a regulatory flexibility analysis in 
connection with this action.

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

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 
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

[[Page 17463]]

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 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.

E. Docket

    The docket includes an organized and complete file of all the 
information upon which EPA relied in taking this direct final action. 
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. 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).)

F. 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.

G. 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.

H. 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.''
    This amendment to National Emissions Standards for Magnetic Tape 
Manufacturing Operations does not significantly or uniquely affect the 
communities of Indian tribal governments. 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.

I. Submission to Congress and the General Accounting Office

    Under 5 U.S.C. 801(a)(1)(A) as added by the Small Business 
Regulatory Enforcement Fairness Act of 1996, the EPA submitted a report 
containing this rule and other required information to the U.S. Senate, 
the U.S. House of Representatives and the Comptroller general of the 
General Accounting Office prior to publication of the rule in today's 
Federal Register. This action to amend the currently effective rule is 
not a ``major rule'' as defined by 5 U.S.C. 804(2).

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

[[Page 17464]]

Congress, through OMB, an explanation of the reasons for not using such 
standards. This action does not put forth any technical standards; 
therefore, consideration of voluntary consensus standards was not 
required.
