National Emission Standards for Hazardous Air Pollutants: 
Cellulose Products Manufacturing

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: This action promulgates national emission standards for 
hazardous air pollutants (NESHAP) for cellulose products manufacturing. 
Cellulose products manufacturing includes both the Miscellaneous 
Viscose Processes source category and the Cellulose Ethers Production 
source category. The Miscellaneous Viscose Processes source category 
comprises the cellulose food casing, rayon, cellulosic sponge, and 
cellophane manufacturing industries. The Cellulose Ethers Production 
source category comprises the methyl cellulose, hydroxypropyl methyl 
cellulose, hydroxypropyl cellulose, hydroxyethyl cellulose, and 
carboxymethyl cellulose manufacturing industries. The EPA has 
identified the Miscellaneous Viscose Processes source category and the 
Cellulose Ethers Production source category as including major sources 
of emissions of hazardous air pollutants (HAP), such as carbon 
disulfide (CS2), carbonyl sulfide, ethylene oxide, methanol, 
methyl chloride, propylene oxide, and toluene. The final rule will 
implement section 112(d) of the Clean Air Act (CAA) by requiring all 
major sources to meet HAP emission standards reflecting the application 
of the maximum achievable control technology (MACT). The final rule 
will reduce HAP emissions by approximately 1,600 megagrams per year 
(Mg/yr) (1,700 tons per year (tpy)). In addition, the final rule will 
reduce hydrogen sulfide (H2S) emissions by approximately 410 
Mg/yr (450 tpy).

EFFECTIVE DATE: June 11, 2002.

I. Background and Public Participation

    Section 112 of the CAA requires us to list categories and 
subcategories of major sources and area sources of HAP and to establish 
NESHAP for the listed source categories and subcategories. A major 
source of HAP is any stationary source or group of stationary sources 
located within a contiguous area and under common control that emits or 
has the potential to emit any single HAP at a rate of 9.1 Mg/yr (10 
tpy) or more or any combination of HAP at a rate of 23 Mg/yr (25 tpy) 
or more.
    Section 112 of the CAA requires that we establish NESHAP for the 
control of HAP from both new and existing major sources. The CAA 
requires the NESHAP to reflect the maximum degree of reduction in 
emissions of HAP that is achievable. This level of control is commonly 
referred to as MACT.
    The MACT floor is the minimum control level allowed for NESHAP and 
is defined under section 112(d)(3) of the CAA. In essence, the MACT 
floor ensures that the standard is set at a level that assures that all 
major sources achieve the level of control at least as stringent as 
that already achieved by the better-controlled and lower-emitting 
sources in each source category or subcategory. For new sources, the 
MACT floor cannot be less stringent than the emission control that is 
achieved in practice by the best-controlled similar source. The MACT 
standards for existing sources can be less stringent than standards for 
new sources, but they cannot be less stringent than the average 
emission limitation achieved by the best-performing 12 percent of 
existing sources in the category or subcategory (or the best-performing 
five sources for categories or subcategories with fewer than 30 
sources).
    In developing MACT, we also consider control options that are more 
stringent than the floor. We may establish standards more stringent 
than the floor based on the consideration of cost of achieving the 
emissions reductions, any non-air quality health and environmental 
impacts, and energy requirements.
    On July 16, 1992 (57 FR 31576), we published an initial list of 
source categories slated for regulation under section 112(c) of the 
CAA. That initial list included the Cellulose Food Casings, Rayon, 
Cellophane, Methyl Cellulose, Carboxymethyl Cellulose, and Cellulose 
Ethers Production source categories. The Cellulose Ethers Production 
source category on the initial list included the hydroxyethyl 
cellulose, hydroxypropyl cellulose, and hydroxypropyl methyl cellulose 
manufacturing industries.
    In developing the proposed rule for cellulose products 
manufacturing, we identified another cellulose products manufacturing 
industry, cellulosic sponge manufacturing, that was not on the initial 
source category list. We added Cellulosic Sponges to the source 
category list on November 18, 1999 (64 FR 63026) in accordance with 
section 112(c) of the CAA.
    We proposed the standards for cellulose products manufacturing on 
August 28, 2000 (65 FR 52166). In the proposal, we combined the various 
cellulose products manufacturing source categories on the initial 
source category list with the Cellulosic Sponge source category to 
create two new source categories. Specifically, we combined the 
existing Cellulose Food Casing, Rayon, Cellulosic Sponge, and 
Cellophane source categories to create a new source category which is 
called ``Miscellaneous Viscose Processes.'' We combined the existing 
Methyl Cellulose, Carboxymethyl Cellulose, and Cellulose Ethers 
Production source categories to create a newly expanded ``Cellulose 
Ethers Production'' source category. On February 12, 2002 (67 FR 6521), 
we published an updated source category list that includes the 
Miscellaneous Viscose Processes and Cellulose Ethers Production source 
categories.
    As in the proposal, the final standards for cellulose products 
manufacturing give most existing sources 3 years from the date of 
promulgation to comply. The final standards also give existing rayon 
operations 8 years from the date of promulgation to comply with the 40 
percent reduction emission limit for their viscose process vents. 
Sources that begin construction or reconstruction after August 28, 2000 
must comply with the standards for new sources by June 11, 2002 or upon 
startup, whichever is later.
    Emission limits, operating limits, and work practice standards, as 
well as initial and continuous compliance requirements, and 
notification, reporting, and recordkeeping requirements are included in 
the final rule. All of these components are necessary to ensure that 
sources comply with the standards both initially and over time. 
However, we have made every effort to simplify the requirements in the 
rule.
    The preamble for the proposed standards described the rationale for 
the proposed standards. Public comments were solicited at the time of 
proposal. The public comment period lasted from August 28, 2000 to 
October 27, 2000. Industry representatives, regulatory agencies, 
environmental groups, and the general public were given the opportunity 
to comment on the proposed rule and to provide additional information 
during and after the public comment period. Although we offered at 
proposal the opportunity for oral presentation of data, views, or 
arguments concerning the proposed rule, no one requested a hearing, and 
a hearing was not held.
    We received a total of 23 letters containing comments on the 
proposed rule during and after the public comment period. Commenters 
included individual cellulose products manufacturing companies, 
industry trade associations, and an association of State and local 
regulatory agencies. Today's final rule reflects our full consideration 
of all of the comments received. Major public comments on the proposed 
rule, along with our responses to those comments, are summarized in 
this preamble. See the Summary of Public Comments and Responses 
memorandum for a more detailed discussion of public comments and our 
responses (Docket No. A-99-39).

II. Summary of Major Changes Since Proposal

    The major changes made to the proposed rule based on public 
comments are described in the sections below. A more comprehensive 
summary of changes can be found in Docket No. A-99-39.

A. All Affected Sources

    In today's final rule, we have added an exemption for research and 
development facilities. We have revised the definition for ``process 
vent'' to include exemptions for small vents with very low 
concentrations and flow rates. We have added a section that discusses 
the overlap between the requirements of the final rule and the 
requirements of other rules.
    We have added definitions for ``process unit'' and revised 
definitions for ``operation'' for the various viscose process and 
cellulose ether industries to provide greater clarification of what is 
covered under the final rule. Each process unit includes all equipment 
used to manufacture the respective products and any associated storage 
vessels, liquid streams in open systems, and equipment components. Each 
operation includes the collection of the

[[Page 40046]]

respective process units and other equipment, including heat exchanger 
systems, wastewater and waste management units, and cooling towers.
    Consistent with the revised definitions for ``operation'' for the 
various viscose process and cellulose ether industries, we have adopted 
work practice standards for heat exchanger systems from 40 CFR 63.104. 
For all affected sources with a closed-vent system containing a bypass 
line that could divert a vent stream away from a control device, we 
have adopted work practice standards for bypass lines from 40 CFR 
63.148. In order to provide this exemption, we have adopted the related 
work practice standards for closed-vent systems from 40 CFR 63.148. We 
have also adopted the applicable initial and continuous compliance 
provisions, reporting and recordkeeping provisions, and definitions 
associated with heat exchanger systems, bypass lines, and closed-vent 
systems from 40 CFR part 63, subparts F and G of the Hazardous Organic 
NESHAP (HON).
    We have reduced the number of biofilter operating limits to three 
(pressure drop, inlet gas temperature, and effluent pH), which would be 
less burdensome and more easily measurable than the eight operating 
limits at proposal. We have also added alternative parameters for 
condensers (outlet liquid temperature) and scrubbers (conductivity and 
alkalinity).
    We have clarified the proposed performance test requirements to 
require that all affected sources conducting a performance test only 
test the inlet and outlet of their control device. We are not requiring 
sources to test their uncontrolled stacks. We have revised the batch 
process vent testing provisions, replacing the worst-case testing 
provisions adopted from 40 CFR 63.1257 with alternative testing 
provisions adopted from 40 CFR 63.490. We have added two voluntary 
consensus standards as alternatives to EPA Methods 3B and 18. We have 
added performance test exemptions for boilers, process heaters, and 
hazardous waste incinerators that meet certain conditions specified in 
the final rule. We have clarified the initial compliance requirements 
to state that sources are not required to conduct a performance test to 
determine the flare control efficiency, based on the assumption that a 
properly operated flare will achieve an emission reduction of 98 
percent.
    We have changed the deadline for conducting the initial compliance 
demonstration from 180 days before to 180 days after the compliance 
date. To enable affected sources to demonstrate compliance between the 
compliance date and the date of the initial compliance demonstration, 
we have added a provision requiring sources to maintain an operation 
and maintenance (O&M) log of the process and emissions control 
equipment during this period.
    We have adopted the methods in 40 CFR 63.505 for determining 
operating limits to allow sources to establish operating limits for 
batch process vents based on the average of all values obtained during 
the compliance demonstration and to establish operating limits for 
continuous process vents (and combined batch and continuous process 
vents) based on the average of the maximum (or minimum) values of the 
parameter.
    For those sources that decide to use continuous emissions 
monitoring systems (CEMS) to demonstrate compliance, we have added CEMS 
performance specifications, recordkeeping and reporting provisions, and 
monitoring installation, operation, and maintenance provisions. We have 
replaced the proposed requirement for 3-hour averages of recorded 
readings with daily averages. We have changed the proposed data 
availability requirement for valid hourly data from 66 percent of every 
averaging period (e.g., two valid hourly values for a 3-hour averaging 
period) to 75 percent of the hours during an operating day. A valid 
hour of data means that sources must have data for all 15-minute 
periods that were not excluded for no flow.
    We have revised the submittal date for the notification of 
compliance status (NOCS) report to require that it be submitted 240 
days after the compliance date, rather than 60 days after completion of 
the initial performance test or 30 days after completion of the initial 
compliance demonstration. In this way, if sources conduct more than one 
test or other compliance demonstration, they would not have to submit 
multiple NOCS reports at different times.
    We have also replaced the requirement that sources submit immediate 
startup, shutdown, and malfunction (SSM) reports if they take actions 
inconsistent with this SSM plan. Now, sources must submit those reports 
with the next semiannual compliance report.
    We have extended the report filing deadline for semiannual 
compliance reports from 30 to 60 days after the end of the compliance 
period, consistent with 40 CFR part 63, subpart G HON, because some 
sources are subject to several NESHAP.

B. Viscose Process Affected Sources

    We have revised the proposed 55 percent reduction emission limit 
for viscose process vents at existing rayon operations. In today's 
final rule, we are requiring existing rayon operations to meet a two-
stage emission reduction requirement--35 percent reduction within 3 
years after the effective date and 40 percent reduction within 8 years 
after the effective date. We have revised the compliance dates for 
existing rayon operations accordingly. We have also revised the 
proposed 85 percent reduction emission limit for viscose process vents 
at cellophane operations. In today's final rule, we are requiring 
cellophane operations to meet a 75 percent reduction emission limit.
    We have added a fourth alternative standard for CS2 
unloading and storage operations that allows affected sources to comply 
by installing a nitrogen unloading system and obtaining a 0.045 percent 
reduction from viscose process vents. We have also added initial and 
continuous compliance provisions and recordkeeping provisions that 
correspond to this alternative. We have clarified that the 83 percent 
reduction emission limit, and the corresponding initial and continuous 
compliance provisions, for CS2 unloading and storage 
operations apply to affected sources using an alternative control 
technique not listed in the final rule.
    We have revised the initial compliance demonstration requirements 
to require viscose process affected sources to conduct a month-long 
compliance demonstration to demonstrate initial compliance, as opposed 
to the 3-hour performance test specified at proposal. The sources would 
report the results of the initial compliance demonstration in the NOCS 
report and keep records of the initial compliance demonstration. The 
sources would also establish their operating limits over the period of 
the month-long compliance demonstration.
    Affected sources that use recovery devices and/or process changes 
to meet the applicable emission limit would demonstrate initial 
compliance during the month-long compliance demonstration using 
information on raw material receipts, measured CS2 
recovered, etc., in their material balance calculations to determine 
their overall percent reduction in emissions. No recovery device 
testing would be necessary.
    Affected sources that must use non-recovery control devices to meet 
the applicable emission limit would be required to conduct a 
performance test to determine the control efficiency of

[[Page 40047]]

their non-recovery control device. The sources would incorporate this 
control efficiency information into their material balance 
calculations, which they would use during the month-long compliance 
demonstration to determine their overall percent reduction in 
emissions.

C. Cellulose Ether Affected Sources

    In today's final rule, we have revised the definition for 
``cellulose ether process'' to specifically exclude solids handling 
steps downstream of the drying process. We have replaced 40 CFR part 
65, subpart F (Consolidated Air Rule), with 40 CFR part 63, subpart UU 
(Generic MACT NESHAP), as an alternative to 40 CFR part 63, subpart H 
(HON), for equipment leak provisions. We have added work practice 
standards for maintenance wastewater from 40 CFR 63.105 and liquid 
streams in open systems from 40 CFR 63.149. We have also adopted the 
applicability provisions, initial and continuous compliance provisions, 
reporting and recordkeeping provisions, and definitions associated with 
equipment leaks, wastewater, and liquid streams in open systems from 40 
CFR part 63, subparts F, G, and H of the HON.
    We have eliminated the proposed requirement for cellulose ether 
affected sources to demonstrate continuous compliance by complying with 
an ongoing 99 percent reduction determination. However, these sources 
must still comply with the applicable operating limits to demonstrate 
continuous compliance. We have added initial and continuous compliance 
requirements and recordkeeping requirements for sources using extended 
cookout to comply with the 99 percent reduction emission limit. We have 
added a voluntary consensus standard as an alternative to EPA Method 
624.

III. Summary of Responses to Major Comments

    This section summarizes major comments we received on the proposed 
rule and our responses to those comments. Only those major comments 
that resulted in an appreciable change to the proposed rule are 
included. A more comprehensive summary of comments and responses can be 
found in Docket No. A-99-39.

A. Emission Limits, Operating Limits, and Work Practice Standards

    Comment: One commenter did not support the process vent MACT floor 
for rayon operations (55 percent reduction). The commenter stated that 
selecting the highest CS2 recovery operation as the MACT 
floor is not appropriate because both rayon operations have control 
equipment in place. The commenter stated that the fairest, most 
equitable approach would be to average the 25 and 55 percent control 
levels of the two rayon operations, resulting in an average 40 percent 
MACT floor control level which the commenter felt their rayon operation 
could meet with available technology. The commenter estimated that, 
because of their fragile business environment, a 35 percent reduction 
is the maximum that their rayon operation could achieve in the next 3 
years, and they requested an additional 5 years (8 years total) to make 
the additional investment to meet a 40 percent MACT floor control 
level.
    Response: Due to the shutdown of the MACT floor rayon operation, 
the commenter's lesser-controlled rayon operation is the only remaining 
rayon operation in the United States. Because the shutdown occurred 
after proposal, we have the option of keeping the current 55 percent 
reduction as the MACT floor or establishing a less stringent MACT 
floor. In light of the shutdown of the only other rayon operation 
providing information regarding available control technology, we have 
decided to establish a less stringent MACT floor (40 percent), which 
the commenter stated would be achievable with available technology. 
This less stringent MACT floor is higher than the 25 percent control 
level achieved by the commenter's rayon operation at proposal. Based on 
the information provided by the commenter, we have decided to implement 
a staged reduction strategy to facilitate the remaining rayon 
operation's achieving the 40 percent MACT floor control level. In 
today's final rule, we are requiring the remaining rayon operation to 
achieve a 35 percent reduction by 3 years after the effective date and 
achieve a 40 percent reduction 5 years later (8 years after the 
effective date).
    Comment: One commenter stated that the 85 percent MACT floor 
control rate for viscose process vents at cellophane operations is 
overstated. The commenter stated that because theirs is the only 
cellophane operation in the United States, the MACT floors for the 
cellophane industry should be based on the information that they 
submitted and should reflect their source's current operational status. 
The commenter noted that the 85 percent control rate was based on 
information that they submitted in their response to EPA's section 114 
information collection request (ICR), and their company had been 
operating the cellophane operation for only a few months when the ICR 
was issued. The commenter stated that they did not have long-term data 
on sulfide control rates or operational parameters at the time, so they 
determined the sulfide control rate for their section 114 ICR response 
using annualized engineering estimates based on their best estimate of 
actual operating conditions at the source. Based on new data, which 
they provided to EPA, the commenter calculated that their cellophane 
operation actually controls approximately 75 to 80 percent of total 
uncontrolled sulfide emissions. The commenter recommended that the MACT 
floor control rate be reduced to 75 percent to accurately reflect their 
source's current operational status, taking into account variability in 
the emission control rate.
    Response: We agree with the commenter that the proposed MACT floor 
control rate is overstated. We have examined the corroborating data 
provided by the commenter, agree with the findings, and have revised 
the process vent MACT floor and emission limit for the cellophane 
industry to require 75 percent control of sulfide emissions.
    Comment: Two commenters noted that, in establishing MACT standards 
for CS2 unloading and storage operations, EPA failed to 
address the situation in which a nitrogen control system includes 
CS2 unloading but not CS2 storage. One of the 
commenters requested that EPA add a fourth compliance option to account 
for this situation and allow the reduction of emissions from the 
process vents by the appropriate amount. The commenter noted that their 
source has installed a nitrogen system for CS2 unloading but 
is keeping the existing water system for CS2 storage. The 
commenter stated that EPA should provide appropriate credit for this 
nitrogen unloading system. Analyses by the commenter on the amount of 
CS2 emitted from their storage tanks during tank car 
unloading suggested that the additional reduction of emissions from the 
process vents should be 0.045 percent.
    Response: We agree with the request from the commenter for a fourth 
alternative for sources with nitrogen unloading but no nitrogen padding 
for CS2 storage. The fourth alternative requires affected 
sources to install a nitrogen unloading system and reduce emissions 
from process vents by 0.045 percent, which, based on the commenter's 
data, is equivalent to the emission reduction achieved by converting 
from water padding to nitrogen padding for CS2 storage.

[[Page 40048]]

B. Testing and Initial Compliance Requirements

    Comment: Several commenters from the viscose process industry 
objected to the initial performance testing requirements in the 
proposed rule. Pointing out that their operations have multiple stacks, 
process vents, and control devices, the commenters stated that 
performing tests on all of these simultaneously would be impractical 
and expensive. Commenters noted that the low flow and high humidity 
typical of viscose process vents would make it difficult to obtain a 
flow sufficient for testing. Commenters also pointed out that EPA's 
testing approach would yield a highly concentrated CS2 
emission stream, but EPA's test method (EPA Method 15 in Appendix A of 
40 CFR part 60) is designed for relatively low pollutant 
concentrations. One commenter stated that the inlet/outlet testing 
approach is irrelevant where the entire operation serves as the control 
device, and CS2 is being removed throughout the process. 
Commenters also stated that the initial performance testing 
requirements in the proposed rule would be dangerous to implement. They 
pointed out that EPA Method 15 would require drilling holes and 
inserting a heated probe into the lines before and after the control 
device; these procedures would allow leakage of air into the system and 
invite the risk of fire and explosion because of CS2's wide 
flammable range, very low autoignition temperature, and very low 
autoignition energy.
    Three commenters indicated that the initial performance testing 
requirements are also inconsistent with the material balance approach 
which is the method EPA used to establish the cellulose MACT standards 
and the required method for viscose process affected sources to 
demonstrate ongoing compliance with the cellulose MACT standards. The 
commenter stated that it would make sense to require the demonstration 
of initial compliance to be on the same basis as the demonstration of 
ongoing compliance.
    Two commenters stated that it would also be difficult to get a 
meaningful range of monitoring parameter values from three short tests. 
One of the commenters stated that monitoring parameter values should be 
established based on data from performance tests conducted over a 
longer period, such as 1 month. The two commenters stated that a longer 
test period is necessary, particularly since continuous compliance with 
the various percent emission reduction requirements in the rule is 
based on a 6-month rolling average.
    Response: We acknowledge that the initial compliance requirements 
should be revised for greater clarity. For today's final rule, we are 
requiring viscose process affected sources to demonstrate their initial 
compliance with the applicable percent reduction emission limit by 
conducting a month-long compliance demonstration using a material 
balance for their sources. This approach is consistent with the 
material balance approach presented by the commenters. This material 
balance requirement would not apply to cellulose ether affected 
sources. For those viscose process affected sources that use recovery 
devices (e.g., carbon adsorbers, condensers, or oil absorbers) and/or 
process changes to meet the applicable emission limit, initial 
compliance would be demonstrated during the month-long compliance 
demonstration with material balance calculations using raw material 
receipts, measured CS2 recovered, etc. No recovery device 
testing would be necessary. For those viscose process affected sources 
that must use non-recovery control devices (e.g., biofilters, flares, 
scrubbers, or thermal oxidizers) to meet the applicable emission limit, 
testing would be required at the inlet and outlet of the non-recovery 
control devices to determine the control efficiency of the non-recovery 
control devices. Testing would not be required at uncontrolled stacks. 
The viscose process affected sources would incorporate the control 
efficiency information from the performance test into their material 
balance calculations, which they would then use during the month-long 
compliance demonstration to determine their overall percent reduction 
in emissions.
    We disagree with the commenters' assumption that they would need to 
test everything at their operations simultaneously. We also disagree 
with the commenters' assertions that EPA Method 15 cannot be used on 
viscose process streams because of the high concentration of 
CS2 in the streams. Sources should be able to simply dilute 
the emission stream sample prior to the analysis. Regarding the 
commenters' other concerns about using EPA Method 15, viscose process 
affected sources are not limited to using EPA Method 15 to measure the 
emissions at the inlet and outlet of the control device. Sources are 
being given the option to use an EPA-approved alternative test method 
or emissions monitoring devices such as CEMS to measure the inlet and 
outlet emissions and determine the control efficiency.
    Comment: Three commenters questioned EPA's use of provisions from 
40 CFR part 63, subpart GGG (Pharmaceuticals NESHAP) regarding worst-
case testing conditions for batch process vents. Noting that this 
requirement applies only to vents with control devices, two of the 
commenters argued that the concept of a worst-case scenario is not 
appropriate for the viscose process industries, where the vents are 
uncontrolled. One of these two commenters also noted that, because 
CS2 is emitted during only certain portions of the 
production cycle, the worst-case emission scenario lasts only for a 
matter of minutes, so extrapolating from this scenario would result in 
a very elevated, artificial emission level. The two commenters stated 
that measuring the total amount of HAP emitted over a cycle is the only 
appropriate way to measure CS2 emissions from viscose 
process vents, rather than some artificial worst-case scenario. 
According to one of the commenters, variations inherent in the viscose 
process make it impossible to identify a representative cycle in 
advance, but these variations could be accounted for more effectively 
over a longer period, such as a month-long compliance determination.
    A third commenter stated that in order to generate the absolute 
worst-case conditions required under 40 CFR part 63, subpart GGG, they 
would have to change the way their processes run, which could include 
running at maximum production rates, making the highest-HAP recipe, or 
changing process variables to generate the highest-HAP emission stream. 
According to the commenter, these situations could result in 
substantial amounts of unordered or off-spec product, causing severe 
financial hardship as well as environmental impacts from the disposal 
of the unwanted product and the artificially increased HAP emissions 
from performing the test. Finally, putting their equipment under 
unusual stress could result in expensive breakdowns or even hazards to 
safety or the environment. As one alternative, the commenter suggested 
that EPA defer entirely to 40 CFR part 63, subpart U (Group I Polymers 
and Resins (P&R I) NESHAP) or subpart JJJ (Group IV Polymers and Resins 
(P&R IV) NESHAP) for all batch process vent testing requirements. The 
commenter stated that these provisions would still require them to 
conduct the test during the most rigorous conditions but would not 
damage their equipment or make unwanted products.
    Response: In response to the various comments, we have decided to 
replace the worst-case testing provisions in 40

[[Page 40049]]

CFR part 63, subpart GGG (Pharmaceuticals NESHAP), with alternative 
batch process vent testing provisions in 40 CFR part 63, subpart U (P&R 
I NESHAP). Similar to the approach in subpart GGG, this approach would 
still require industry to conduct the performance test during the most 
rigorous conditions. This change should address the concerns voiced by 
all of the commenters.
    As we have already noted in another response, viscose process 
affected sources that use recovery devices and/or process changes to 
meet the applicable emission limit would demonstrate initial compliance 
during the month-long compliance demonstration with material balance 
calculations, using information about raw material receipts, measured 
CS2 recovered, etc. No recovery device testing would be 
necessary.
    Comment: Several commenters stated that the testing requirements 
during the initial compliance demonstration create problems with 
establishing operating limits. Two of the commenters (viscose process 
operations) stated that it would not be possible to determine suitable 
ranges for the operating limits during only 3 hours of testing in the 
initial performance test. One commenter stated that operating limits 
should be determined over a variety of operating scenarios in order to 
define the boundaries of monitoring parameter values upon which to 
demonstrate compliance. The other commenter stated that a test 
conducted over a longer period, such as 1 month, using their 
operation's proposed material balance method, would identify the full 
acceptable range of parameter values to monitor.
    A third commenter (a cellulose ether operation) recommended that a 
minimum or maximum operating limit be established based on the 
monitoring parameter values measured during the performance test and 
extended beyond those values if it can be demonstrated by engineering 
assessments and/or manufacturer's recommendations that the unit will 
still meet the proposed standard. The commenter stated that performance 
testing should not be required to be conducted over the source's entire 
operational range. The commenter also stated that affected sources 
would have a very narrow window of compliance if monitored parameter 
data are collected during ``normal'' operating conditions and further 
``normalized'' by averaging all the data points. The commenter stated 
that it must be clear that all data points measured during the 
performance test are acceptable. The commenter also stated that the 
source should not be required to retest every time there is some normal 
variation in production relative to the conditions of the initial 
performance test.
    Response: In response to the first two commenters (viscose process 
operations), we have decided to revise the cellulose rule to allow 
viscose process affected sources to establish their operating limits 
over the month-long initial compliance demonstration, which should 
provide the sources sufficient time to establish their operating 
limits.
    In response to one comment by the third commenter (a cellulose 
ether operation), we have decided to revise the procedures for 
determining operating limits consistent with the approach taken in 40 
CFR part 63, subpart U (P&R I NESHAP). For batch process vents, we are 
requiring that sources establish the operating limit based on the 
average of all monitoring values obtained during the performance test 
(or month-long compliance demonstration for viscose process affected 
sources), consistent with the approach in 40 CFR 63.505(b)(3). For 
continuous process vents, we are requiring that the sources establish 
the operating limit based on the average of the maximum (or minimum) 
values of the monitoring parameter for the three test runs (or daily 
averages during the compliance demonstration for viscose process 
affected sources), consistent with the approach in 40 CFR 63.505(b)(2). 
If sources combine their batch and continuous process vents, we are 
requiring that they establish their operating limit using the 
continuous process vent approach.
    In response to another comment by the third commenter, testing 
would not be required over their source's entire operational range. We 
disagree with the third commenter's suggestion to supplement or extend 
the values from the test as in the HON. The HON was written that way 
because we were trying to have the owner/operator justify a range, not 
establish a limit. We have also clarified that affected sources would 
establish what are considered ``normal'' operating conditions for 
continuous operation during the initial performance test. The sources 
would then be required to meet the operating limits established during 
the initial performance test.
    Comment: Several commenters objected to the proposed requirement 
for sources to conduct the initial performance test at least 180 days 
before the compliance date. Commenters argued that EPA had provided no 
justification, as required, for this deviation from EPA's past 
practice. With the notification of performance test due at least 60 
days before the performance test, commenters stated that this would 
require sources to start preparing for the performance test 240 to 360 
days prior to the compliance date in order to be confident that the 
test can be passed. Two commenters noted that requests for an 
alternative monitoring method may have to occur even earlier, making it 
unrealistic for an affected source to apply for EPA approval to use the 
alternative method because of insufficient time to obtain EPA approval 
and purchase and install the alternative equipment. One commenter 
stated that it makes more technical sense to conduct a performance test 
after the unit is required to be in compliance rather than before. 
Therefore, the commenters recommended that EPA revise the deadline for 
performance testing consistent with 40 CFR 63.7(a), which requires an 
initial performance test be conducted within 180 days after the 
compliance date.
    Response: Based on these comments, we have decided to revise the 
proposed requirement and allow sources to complete their performance 
test or other initial compliance demonstration no later than 180 days 
after the compliance date. Our intention for requiring the earlier date 
was to ensure that sources would be in compliance by the compliance 
date and allow sources to avoid severe penalties for noncompliance if 
they found themselves out of compliance based on a test conducted 180 
days after the compliance date. To ensure that a record of compliance 
is kept between the compliance date and the date that operating limits 
are set (i.e., date of the performance test or other initial compliance 
demonstration), today's final rule also requires sources to maintain an 
O&M log of the process and emissions control equipment during this 
period.

C. Continuous Compliance Requirements

    Comment: One commenter suggested that EPA allow outlet liquid 
temperature as an alternative operating limit to outlet gas temperature 
for condensers, stating that this variable is directly related to 
outlet gas temperature and is the control point for changing air 
temperature. Noting that the pH of caustic liquids used in a wet 
scrubber may be on the extreme end of the pH scale, a second commenter 
suggested that EPA allow either a pH or conductivity measuring device 
for determining compliance with the operating limit for wet scrubbers. 
A

[[Page 40050]]

third commenter stated that their operation measures the available 
alkalinity, not the pH, in the circulating system for their wet 
scrubbers, and stated that pH meters would not be as reliable as the 
current system. A fourth commenter stated that liquid flow rate and 
pressure drop measurements do not always indicate the required wet 
scrubber performance. The commenter stated that it is possible for a 
scrubber to meet required control efficiencies and still sustain a 
pressure or liquid flow reduction. The commenter noted that other 
parameters, such as adequate pack height and liquid distribution, are 
technically more accurate indicators of scrubber performance.
    Response: In response to these comments, we have revised the 
proposed requirements to include some of the additional parameters 
requested by commenters (i.e., condenser liquid outlet temperature for 
condensers and conductivity and alkalinity for wet scrubbers). However, 
we have not added adequate pack height and liquid distribution as 
additional wet scrubber parameters because we are not convinced that 
they are good parameters. Adequate pack height is a characteristic of 
the control device, not the kind of parameter that could be monitored 
continuously, and liquid distribution is a difficult type of parameter 
to monitor. Nonetheless, sources have the option under the rule to 
apply to the Administrator for approval to use alternative parameters.
    Comment: One commenter stated that the proposed rule lacks the 
following essential provisions, developed for other MACT standards, 
regarding the proper use of parameter monitoring data for purposes of 
enforcement: (1) Specify that excursions violate an operating limit, 
not an emission limit; (2) base excursions on a 24-hour daily average 
to account for short-term fluctuations, which typically self-correct so 
that the daily average reading is normal; (3) allow a number of excused 
excursions in each semiannual reporting period to account for periods 
when something goes wrong despite how carefully an emission control 
device is designed, operated, and maintained (according to the 
commenter, without excused excursions, sources would be unable to 
ensure compliance); (4) exclude data from certain periods (e.g., 
startups, shutdowns, malfunctions, calibrations, periods of 
nonoperation of all or part of the process) from daily averages because 
those data are of questionable validity; (5) require no monitoring when 
the process is shut down and there are no emissions, and, if sources do 
monitor, specify that the data do not constitute an excursion; (6) 
specify that only one excursion will be assigned if two or more 
parameters go beyond their limits at the same time for the same control 
device; (7) clearly define what constitutes an excursion; and (8) 
specify that some limited percentage of data points can be missing or 
fail to meet applicable criteria without that being an excursion.
    The commenter requested that EPA revise the data availability 
requirement to match 40 CFR part 63, subpart G (HON), for continuous 
vents and wastewater vents and 40 CFR part 63, subpart U (P&R I NESHAP) 
or subpart JJJ (P&R IV NESHAP), for batch vents and storage vessel 
vents. The commenter noted that because the daily average in 40 CFR 
part 63, subpart G, is based on having valid data points for 75 percent 
of the operating day, the actual operating day for a batch process 
could be adjusted for periods when the unit was not operating or not 
sending vents to the control device. The commenter contrasted this with 
the 3-hour averages required in the proposed rule, which may or may not 
coincide accurately with the operational time of a batch process.
    In separate comments, two other commenters recommended that EPA 
insert data availability language similar to 40 CFR 60.48b(f) 
(Performance Standard for Industrial-Commercial-Institutional Steam 
Generating Units). According to the commenters, this subpart requires 
that data must be available for a minimum of 75 percent of the 
operating hours for each control device operating day in at least 22 
out of 30 successive control device operating days. The commenters 
stated that this change would allow EPA to account for the realities of 
operating computerized systems, which require periodic backup and 
occasionally break down and cannot be repaired in 1 hour in order to 
comply with the proposed 66 percent data availability requirement 
(e.g., two valid hourly values for a 3-hour averaging period).
    Response: Regarding the first requested provision, the proposed 
rule does not link deviations in operating limits with violations of 
emission limits.
    Regarding the second provision, the concept of a 24-hour average 
would be consistent with other rules and seems reasonable. Therefore, 
we have made the requested change to today's final rule.
    Regarding the third provision, we are not allowing excused 
excursions (deviations) in today's final rule. Excused excursions were 
allowed in the HON to give sources time to become familiar with the new 
monitoring provisions in the HON. The excursions were not meant to be 
precedent-setting for all future rules. We believe that industry in 
general has had sufficient time to develop strategies for complying 
with monitoring requirements, and that excused excursions are no longer 
necessary. Other recent rules also have been issued without excused 
excursions.
    Regarding the fourth and fifth provisions, there is no problem with 
including the requested exemption for periods of nonoperation for all 
or part of a source, and we have made the requested change to today's 
final rule. However, we are not adding exemptions to today's final rule 
for startups, shutdowns, and malfunctions. According to 40 CFR 
63.6(e)(1)(i) of the NESHAP General Provisions, sources are required to 
minimize emissions during periods of startup, shutdown, or malfunction. 
If the daily average parameter value (including data from the startup, 
shutdown, or malfunction period) does not exceed the specified limit, 
then there is no deviation to report. However, deviations on days when 
you have startup, shutdown, or malfunction events would not be 
violations if you follow the procedures in your SSM plan.
    Regarding the sixth provision, we have not included the requested 
exemption to allow sources only one excursion when two or more 
parameters go beyond their limits at the same time for the same control 
device. We do not want to specify in each rule exactly how we are going 
to assess penalties.
    Regarding the eighth provision, we agree with the requests from the 
three commenters that the data availability requirements be revised. 
Consistent with the approach taken in 40 CFR part 63, subpart GGG 
(Pharmaceuticals NESHAP) and subpart MMM (Pesticide Active Ingredients 
NESHAP), we are requiring that at least 75 percent of the hours during 
an operating day be valid. We are including a 100 percent data 
availability requirement for a valid hour of data. A valid hour of data 
means that sources must have data for all 15-minute periods that were 
not excluded for no flow. For batch vents, if there is no flow at the 
time when a monitoring reading is taken, then that reading does not 
count in the average. In this way, we are able to take into account 
both batch and continuous vents, with a clear definition of what 
constitutes an excursion in each case, which was requested in the 
seventh provision. However, we do not agree with the request by two of 
the commenters for data to be available in at least 22 out of 30 
successive operating days. We believe that such a

[[Page 40051]]

requirement could create a problem under some situations, such as if a 
source were to shut down for maintenance for an extended period of 
time.

D. Notifications and Reports

    Comment: One commenter recommended that EPA revise the proposed 
cellulose rule to require that all NOCS reports be due on the same date 
following the compliance date, rather than after a certain number of 
days following the initial performance test or the initial compliance 
demonstration. According to the commenter, multiple performance tests 
for a process unit would make the original requirement to submit based 
on the performance test date very confusing, possibly requiring sources 
to submit multiple NOCS reports at various times, making it very easy 
to miscalculate a date and create inadvertent noncompliance. The 
commenter stated that there should also be no difference in the 
timeframe to submit the NOCS reports based on whether or not a 
performance test is required. According to the commenter, it would be 
more efficient for sources to send, and for EPA to receive, one set of 
NOCS reports. The commenter recommended that EPA take a standardized 
approach to NOCS reports by adding text similar to 40 CFR 63.152(b) and 
deleting references to 40 CFR 63.9(h) and 63.10(d)(2), which address 
the submittal dates for NOCS reports.
    Response: We agree with the commenter that requiring sources to 
submit NOCS reports at various times could be confusing. To eliminate 
this source of confusion, we have decided to tie the date to submit all 
initial NOCS reports to the compliance date rather than the test date. 
Sources would be required to submit the NOCS reports no later than 240 
days after the compliance date. This submittal date is based on the 
requirements in 40 CFR part 63, subpart A (NESHAP General Provisions), 
to conduct the initial performance test no later than 180 days after 
the compliance date and submit the NOCS report no later than 60 days 
after the performance test (180 days plus 60 days equals 240 days). To 
accomplish this standardized schedule, we have, as suggested, adapted 
text from 40 CFR 63.152(b) for today's final rule and excluded the 
provisions of 40 CFR 63.9(h) and 63.10(d)(2) regarding the submittal 
date for NOCS reports.

IV. Summary of Impacts

A. Air Quality Impacts

    We have determined nationwide baseline HAP emissions from existing 
sources in the Miscellaneous Viscose Processes source category and 
Cellulose Ethers Production source category to be approximately 12,800 
Mg/yr (14,100 tpy) at the current level of control. We have determined 
that the promulgated standards will reduce total HAP emissions from 
these sources by approximately 1,600 Mg/yr (1,700 tpy).
    In addition to reducing emissions of HAP, the promulgated standards 
will also reduce emissions of non-HAP, such as H2S. We have 
determined that the promulgated standards will reduce H2S 
emissions from existing sources by approximately 410 Mg/yr (450 tpy) 
from a baseline level of approximately 2,800 Mg/yr (3,100 tpy).
    We have determined that the promulgated standards will increase 
secondary emissions of criteria pollutants (particulate matter, sulfur 
dioxide, carbon monoxide, and nitrogen oxides) by approximately 190 Mg/
yr (210 tpy). Secondary emissions were assumed to be generated from the 
utility boilers that produce the electricity and the industrial boilers 
that produce the steam for the control devices.

B. Cost Impacts

    We have determined that the capital costs of the promulgated 
standards for existing sources will be approximately $30.8 million for 
emission control and $0.6 million for monitoring, which results in a 
total capital cost of approximately $31.4 million. The capital costs 
include the costs to purchase and install the emission control and 
monitoring equipment.
    We have determined that the total annual costs for the rule will be 
approximately $9.7 million. Specifically, we have determined that the 
incremental annual costs of the promulgated standards for existing 
sources will be approximately $9.2 million for emission control and 
$0.4 million for monitoring. The annual costs include the direct annual 
costs (comprised of labor, materials, and utilities) plus the indirect 
annual costs (comprised of overhead, taxes, insurance, administrative 
charges, and capital recovery).
    In addition, we expect that the total annual costs for 
recordkeeping and reporting required by the promulgated standards for 
existing sources will average approximately $67,900 over the first 3 
years after implementation of the standards. We project no new sources 
over the first 3 years after implementation of the standards.

C. Economic Impacts

    Because of the variability in end products in cellulose products 
manufacturing, we assessed impacts on five separate market segments. We 
treated the Cellulose Ethers Production source category as one segment, 
and divided the Miscellaneous Viscose Processes source category into 
four segments: cellulose food casing, rayon, cellulosic sponge, and 
cellophane. The total annualized social cost (in 1998 dollars) of the 
final rule on the industry is $6.0 million, with costs to the firms 
affected by the final rule ranging from 0.01 to 1 percent of sales.
    For individual facilities, the cost-to-sales ratios ranged from 
less than 0.01 to 8.2 percent of sales. Since the higher facility cost-
to-sales ratios were found among the cellulose food casing, rayon, and 
cellulosic sponge segments, we performed a market analysis, using 1998 
as the baseline. The results indicated less than 1.5 percent change in 
both the market prices and in the quantity produced for the cellulose 
food casing and cellulosic sponge segments.
    One of the two rayon firms has left the market since the proposal 
of this rule. For this reason, the remaining firm was modeled assuming 
full absorption of the control costs. This firm was already operating 
with a negative profit. It is possible that the closure of the other 
rayon firm may increase sales and profitability for the remaining firm. 
However, this is uncertain given the decline in the rayon industry 
since 1998. Available economic data suggest that an additional facility 
in this source category has experienced negative profits since 1998, so 
two facilities could reasonably close if current trends in the industry 
continue, even if they did not incur compliance costs from the final 
rule. The impact of the promulgated standards may be that the closures 
may occur sooner than they would otherwise.

D. Non-Air Environmental Impacts

    We have determined that wastewater generation for existing sources 
will increase by approximately 8.1 million liters per year (L/yr) (2.1 
million gallons per year (gal/yr)) relative to a baseline level of 
approximately 23 billion L/yr (6.2 billion gal/yr), and solid waste 
generation will increase by approximately 420 Mg/yr (460 tpy). We 
determined these impacts based on the additional wastewater and solid 
waste generated by control devices (e.g., Lo-Cat[reg] scrubbers and 
carbon adsorbers) installed to meet the promulgated

[[Page 40052]]

standards for existing sources. We do not expect these increased 
impacts to adversely affect the ability of sources to comply with the 
promulgated standards.

E. Energy Impacts

    We have determined that the overall energy demand (electricity plus 
steam) for existing sources in the Miscellaneous Viscose Processes 
source category and Cellulose Ethers Production source category will 
increase by approximately 300 million megajoules per year (284 billion 
British thermal units per year) under the promulgated standards. We 
determined this net increase based on the additional energy demand for 
control devices (e.g., scrubbers, carbon adsorbers, condensers, and oil 
absorbers) installed or upgraded to meet the promulgated standards for 
existing sources. We do not expect this increased energy demand to 
adversely affect the ability of sources to comply with the promulgated 
standards.

V. Administrative Requirements

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 review by the Office of Management and Budget 
(OMB) 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 obligation 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, it has been 
determined that this rule is not a ``significant regulatory action'' 
because none of the listed criteria apply to this action. Consequently, 
this action was not submitted to OMB for review under Executive Order 
12866.

B. 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'' are 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 
regulation. The EPA also may not issue a regulation that has federalism 
implications and that preempts State law unless EPA consults with State 
and local officials early in the process of developing the regulation.
    If EPA complies by consulting, Executive Order 13132 requires EPA 
to provide to 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 EPA'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, it must include a certification from 
EPA's Federalism Official stating that EPA has met the requirements of 
Executive Order 13132 in a meaningful and timely manner.
    The final rule does not have federalism implications. It 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. Thus, the requirements of 
section 6 of the Executive Order do not apply to the rule.

C. 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.''
    The final rule does not have tribal implications, as specified in 
Executive Order 13175. Thus, Executive Order 13175 does not apply to 
the rule.

D. 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 
rule is preferable to other potentially effective and reasonably 
feasible alternatives that EPA considered.
    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 rule. Today's rule is not subject to 
Executive Order 13045 because it is based solely on technology 
performance. No children's risk analysis was performed because no 
alternative technologies exist that would provide greater stringency at 
a reasonable cost. Furthermore, the rule has been determined not to be 
``economically significant'' as defined under Executive Order 12866.

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

    Today's final rule is not subject to Executive Order 13211 (66 FR 
28355, May 22, 2001) because it is not a significant regulatory action 
under Executive Order 12866.

F. Unfunded Mandates Reform Act of 1995

    Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), Public 
Law 104-4, establishes requirements for

[[Page 40053]]

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 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 this 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, enabling officials of 
affected small governments to have meaningful and timely input in the 
development of EPA's 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 today's final rule 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 1 year. The capital cost of the rule has been 
determined to be approximately 31.4 million. The maximum total annual 
cost of the final rule for any year has been determined to be 
approximately $9.7 million. Thus, today's final rule is not subject to 
the requirements of sections 202 and 205 of the UMRA. In addition, EPA 
has determined that the final rule contains no regulatory requirements 
that might significantly or uniquely affect small governments because 
it contains no requirements that apply to such governments or impose 
obligations upon them. Therefore, today's final rule is not subject to 
the requirements of section 203 of the UMRA.

G. Regulatory Flexibility Act (RFA), as Amended by the Small Business 
Regulatory Enforcement Fairness Act of 1996 (SBREFA), 5 U.S.C. 601 et 
seq.

    The RFA generally requires an agency to prepare 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 on 
small entities, a small entity is defined as: (1) A small business that 
has fewer than 1,000 employees for NAICS codes 325221, 325188, and 
325199; fewer than 750 employees for NAICS code 325211; or fewer than 
500 employees for NAICS codes 326121 and 326199; (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, it has been determined that this action will not have a 
significant economic impact on a substantial number of small entities. 
We have determined that only one firm meets one of the definitions of 
small entity--a small business that has fewer than 500 employees for 
NAICS code 326199. This firm owns only 1 of the 13 operations subject 
to today's final rule. There are several firms subject to today's final 
rule whose costs will be a greater percentage of sales than this small 
business. Furthermore, the market impacts on this firm are minimal and 
are in line with impacts experienced by other firms subject to today's 
final rule.

H. Paperwork Reduction Act

    The information collection requirements in the final rule will be 
submitted for approval to OMB under the Paperwork Reduction Act, 44 
U.S.C. 3501 et seq. The EPA has prepared an Information Collection 
Request (ICR) document (ICR No. 1974.02), and you may obtain a copy 
from Sandy Farmer by mail at the Office of Environmental Information, 
Collection Strategies Division (2822), U.S. EPA, 1200 Pennsylvania 
Avenue, NW., Washington, DC 20460; by electronic mail at 
[email protected]; or by calling (202) 260-2740. You may also 
download a copy off the Internet at http://www.epa.gov/icr. The 
information requirements are not effective until OMB approves them.
    The information requirements are based on notification, 
recordkeeping, and reporting requirements in 40 CFR part 63, subpart A 
(NESHAP General Provisions), which are mandatory for all operators 
subject to national emission standards. These recordkeeping and 
reporting requirements are specifically authorized by section 114 of 
the CAA (42 U.S.C. 7414). All information submitted to EPA pursuant to 
the recordkeeping and reporting requirements for which a claim of 
confidentiality is made is safeguarded according to EPA's policies set 
forth in 40 CFR part 2, subpart B.
    Today's final rule would require maintenance inspections of the 
control devices but would not require any notifications or reports 
beyond those required by 40 CFR part 63, subpart A (NESHAP General 
Provisions). The recordkeeping requirements require only the specific 
information needed to determine compliance.
    The annual recordkeeping and reporting burden for this collection 
(averaged over the first 3 years after the effective date of the rule) 
has been determined to be approximately 1,400 labor hours per year, at 
a total annual cost of approximately $67,900. This burden estimate 
includes one-time notifications of applicability and performance test, 
reading instructions, training personnel, and developing a record 
system, SSM plan, and site-specific monitoring plan. The total 
annualized capital cost for monitoring equipment and for file cabinets 
used for storing collected data and reports averages approximately 
$56,600 over the 3-year period of the ICR. The total annual O&M cost 
for file storage, photocopying, and postage for notifications and 
reports averages approximately $200 over the 3-year period of the ICR.
    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: (1) Review instructions; (2) 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; (3) adjust the 
existing ways to comply with any previously applicable instructions and

[[Page 40054]]

requirements; (4) train personnel to be able to respond to a collection 
of information; (5) search data sources; (6) complete and review the 
collection of information; and (7) 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.

I. National Technology Transfer and Advancement Act of 1995

    As noted in the proposed rule, section 12(d) of the National 
Technology Transfer and Advancement Act of 1995 (NTTAA), Public Law 
104-113, section 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) 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.
    Today's final rule involves the following technical standards: EPA 
Methods 1, 1A, 2, 2A, 2C, 2D, 2F, 2G, 3, 3A, 3B, 4, 15, 18, 21, 22, 25, 
and 25A (40 CFR part 60, appendix A); Performance Specification 7 (PS-
7), PS-8, PS-9, and PS-15 (40 CFR part 60, appendix B); and the 
applicable wastewater test methods and procedures in 40 CFR 63.144 and 
63.145. Consistent with the NTTAA, EPA conducted searches to identify 
voluntary consensus standards in addition to these EPA methods and 
performance specifications. The search and review results were 
documented and placed in the docket for today's final rule (Docket No. 
A-99-39).
    No applicable voluntary consensus standards were identified as 
alternatives to EPA Methods 1A, 2A, 2D, 2F, 2G, 22, PS-7, PS-8, PS-9, 
and PS-15 for the purposes of the rule. However, three voluntary 
consensus standards were identified as acceptable alternatives to EPA 
Methods 3B, 18, and 624 for the purposes of the rule. The three 
standards are ASME Performance Test Code (PTC) 19.10-1981--Part 10 
(Flue and Exhaust Gas Analysis), ASTM D6420-99 (Standard Test Method 
for Determination of Gaseous Organic Compounds by Direct Interface Gas 
Chromatography-Mass Spectrometry (GC/MS)), and ASTM D5790-95 (Standard 
Test Method for Measurement of Purgeable Organic Compounds in Water by 
Capillary Column Gas Chromatography-Mass Spectrometry).
    The voluntary consensus standard ASME PTC 19.10-1981--Part 10 is 
cited in today's final rule for its manual method for measuring the 
oxygen, carbon dioxide, and carbon monoxide content of exhaust gas. 
This part of ASME PTC 19.10-1981--Part 10 is an acceptable alternative 
to EPA Method 3B.
    The voluntary consensus standard ASTM D6420-99 is appropriate in 
certain cases as an alternative to EPA Method 18 for the measurement of 
toluene and total organic HAP. Similar to EPA Method 18, ASTM D6420-99 
is also a performance-based method for measuring gaseous organic 
compounds. However, ASTM D6420-99 was written to support the specific 
use of highly portable and automated GC/MS. While offering advantages 
over the traditional EPA Method 18, the ASTM method does allow some 
less stringent criteria for accepting GC/MS results than required by 
EPA Method 18. Therefore, ASTM D6420-99 is a suitable alternative to 
EPA Method 18 only where: (1) The target compound(s) are those listed 
in Section 1.1 of ASTM D6420-99, and (2) the target concentration is 
between 150 parts per billion by volume and 100 parts per million by 
volume. For target compound(s) not listed in Section 1.1 of ASTM D6420-
99, but potentially detected by mass spectrometry, today's final rule 
specifies that the additional system continuing calibration check after 
each run, as detailed in Section 10.5.3 of the ASTM method, must be 
followed, met, documented, and submitted with the data report even if 
there is no moisture condenser used or the compound is not considered 
water soluble. For target compound(s) not listed in Section 1.1 of ASTM 
D6420-99 and not amenable to detection by mass spectrometry, ASTM 
D6420-99 does not apply. As a result, EPA will cite ASTM D6420-99 in 
today's final rule. The EPA will also cite EPA Method 18 as a gas 
chromatography (GC) option in addition to ASTM D6420-99, which will 
allow the continued use of GC configurations other than GC/MS.
    The voluntary consensus standard ASTM D5790-95 is a ``purge and 
trap'' method that is acceptable as an alternative analytical procedure 
for the wastewater test methods and procedures in 40 CFR 63.144 and 
63.145 for the analysis of total organic HAP in wastewater samples. As 
a result, EPA will cite ASTM D5790-95 in today's final rule. However, 
this ASTM method should be used with the sampling procedures of EPA 
Method 25D or an equivalent method in order to be a complete 
alternative for the purposes of this rule, as per 40 CFR 63.144. The 
standard ASTM D5790-95 is similar to EPA Method 624, which is also a 
``purge and trap'' procedure. The standard ASTM D5790-95 is validated 
for all of the 21 volatile organic HAP targeted by EPA Method 624, but 
it is also validated for an additional 14 HAP not targeted by the EPA 
method.
    In addition to the three voluntary consensus standards EPA uses in 
the rule, the search for emissions measurement procedures identified 14 
other voluntary consensus standards as potential alternatives to EPA 
Methods 1, 2, 2C, 3, 3A, 3B, 4, 15, 18, 21, 25, and 25A. The EPA 
determined that 12 of the 14 standards identified for measuring 
emissions of the HAP or surrogates subject to emission limits in 
today's final rule were impractical alternatives to EPA test methods 
for the purposes of the rule. Two of the 14 standards identified in the 
search were not available at the time the review was conducted because 
they are under development by a voluntary consensus body. For these 
reasons, EPA does not intend to adopt these 14 standards for today's 
final rule.
    Sections 63.5535 and 63.5545 and Table 4 to Subpart UUUU of 40 CFR 
part 63 list the EPA test methods and performance specifications 
included in today's final rule. Under 40 CFR 63.7(f) and 63.8(f) of the 
NESHAP General Provisions, an affected source may apply to EPA for 
permission to use alternative test methods or alternative monitoring 
requirements in place of any of the EPA test methods, performance 
specifications, or procedures.

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 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 this 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 rule in the Federal

[[Page 40055]]

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). This rule is effective June 11, 2002.

What This Subpart Covers


Sec. 63.5480  What is the purpose of this subpart?

    This subpart establishes emission limits, operating limits, and 
work practice standards for hazardous air pollutants (HAP) emitted from 
cellulose products manufacturing operations. Carbon disulfide, carbonyl 
sulfide, ethylene oxide, methanol, methyl chloride, propylene oxide, 
and toluene are the HAP emitted in the greatest quantities from 
cellulose products manufacturing operations. This subpart also 
establishes requirements to demonstrate initial and continuous 
compliance with the emission limits, operating limits, and work 
practice standards.


Sec. 63.5485  Am I subject to this subpart?

    You are subject to this subpart if you own or operate a cellulose 
products manufacturing operation that is located at a major source of 
HAP emissions.
    (a) Cellulose products manufacturing includes both the 
Miscellaneous Viscose Processes source category and the Cellulose 
Ethers Production source category. The Miscellaneous Viscose Processes 
source category includes all of the operations that use the viscose 
process. These operations include the cellulose food casing, rayon, 
cellulosic sponge, and cellophane operations, as defined in 
Sec. 63.5610. The Cellulose Ethers Production source category includes 
all of the cellulose ether operations, as defined in Sec. 63.5610, that 
use the cellulose ether process.
    (b) A major source of HAP is any stationary source or group of 
stationary sources located within a contiguous area and under common 
control that emits or has the potential to emit any single HAP at a 
rate of 9.1 megagrams per year (Mg/yr) (10 tons per year (tpy)) or more 
or any combination of HAP at a rate of 23 Mg/yr (25 tpy) or more.
    (c) The provisions of this subpart do not apply to research and 
development facilities, as defined in section 112(b)(7) of the Clean 
Air Act (CAA), regardless of whether the facilities are located at the 
same plant site as an operation subject to the provisions of this 
subpart.
    (d) For cellulose ether operations, the applicability provisions in 
paragraph (d)(1) or (2) of this section apply.
    (1) The applicability provisions in Secs. 63.100(a) through (f) and 
63.160 apply if you are complying with the equipment leak provisions of 
subpart H of this part.
    (2) The applicability provisions in Sec. 63.1019 apply if you are 
complying with the equipment leak provisions in subpart UU of this 
part.
    (e) For cellulose ether operations, the applicability provisions in 
Secs. 63.100(a) through (f) and 63.110(a), (e) and (h) apply if you are 
complying with the wastewater provisions in subparts F and G of this 
part.


Sec. 63.5490  What parts of my plant does this subpart cover?

    (a) This subpart applies to each new, reconstructed, or existing 
affected source for the Miscellaneous Viscose Processes and Cellulose 
Ethers Production source categories.
    (b) The affected source for the Miscellaneous Viscose Processes 
source category is each cellulose food casing, rayon, cellulosic 
sponge, or cellophane operation, as defined in Sec. 63.5610. The 
affected source for the Cellulose Ethers Production source category is 
each

[[Page 40056]]

cellulose ether operation, as defined in Sec. 63.5610.
    (c) You must consider storage vessels to be part of your process 
unit, as defined in Sec. 63.5610, under either of the conditions 
described in paragraphs (c)(1) and (2) of this section. Otherwise, you 
may assign your storage vessels according to paragraph (c)(3) or (4) of 
this section.
    (1) The input to the storage vessel from your viscose process or 
cellulose ether process (either directly or through other storage 
vessels assigned to your process unit) is greater than or equal to the 
input from any other process.
    (2) The output from the storage vessel to your viscose process or 
cellulose ether process (either directly or through other storage 
vessels assigned to your process unit) is greater than or equal to the 
output to any other process.
    (3) If the greatest input to and/or output from a shared storage 
vessel is the same for two or more processes, including at least one 
viscose process or cellulose ether process, you may assign the storage 
vessel to any process unit that has the greatest input or output.
    (4) If the use varies from year to year, then you must base the 
determination on the utilization that occurred during the year 
preceding June 11, 2002 or, if the storage vessel was not operating 
during that year, you must base the use on the expected use for the 
first 5-year period after startup. You must include this determination 
in the Notification of Compliance Status Report specified in Table 7 to 
this subpart.
    (d) An affected source is a new affected source if you began 
construction of the affected source after August 28, 2000 and you meet 
the applicability criteria in Sec. 63.5485 at the time you began 
construction.
    (e) An affected source is reconstructed if you meet the criteria as 
defined in Sec. 63.2.
    (f) An affected source is existing if it is not new or 
reconstructed.
    (g) For the purposes of this subpart, the definitions of new and 
existing affected source in paragraphs (d) through (f) of this section 
supersede the definitions of new and existing affected source in 
subparts F, G, H, U and UU of this part.


Sec. 63.5495  When do I have to comply with this subpart?

    (a) If you have a new or reconstructed affected source, then you 
must comply with this subpart according to the requirements in 
paragraphs (a)(1) and (2) of this section.
    (1) If you start up your affected source before June 11, 2002, then 
you must comply with the emission limits, operating limits, and work 
practice standards for new and reconstructed sources in this subpart no 
later than June 11, 2002.
    (2) If you start up your affected source after June 11, 2002, then 
you must comply with the emission limits, operating limits, and work 
practice standards for new and reconstructed sources in this subpart 
upon startup of your affected source.
    (b) If you have an existing affected source, then you must comply 
with this subpart according to the requirements in paragraphs (b)(1) 
and (2) of this section.
    (1) Cellulose food casing, cellulosic sponge, cellophane, and 
cellulose ether operations must comply with the emission limits, 
operating limits, and work practice standards for existing sources in 
this subpart no later than June 13, 2005.
    (2) Rayon operations must comply with this subpart according to the 
requirements in paragraphs (b)(2)(i) through (iii) of this section.
    (i) Rayon operations must comply with the 35 percent reduction 
emission limit and associated operating limits and work practice 
standards for existing sources in this subpart no later than June 13, 
2005.
    (ii) Rayon operations must comply with the work practice standard 
for carbon disulfide unloading and storage operations for existing 
sources in this subpart no later than June 13, 2005.
    (iii) Rayon operations must comply with the 40 percent reduction 
emission limit and associated operating limits and work practice 
standards for existing sources in this subpart no later than June 11, 
2010.
    (c) If you have an area source that increases its emissions or its 
potential to emit so that it becomes a major source of HAP and an 
affected source subject to this subpart, then the requirements in 
paragraphs (c)(1) and (2) of this section apply.
    (1) An area source that meets the criteria of a new affected 
source, as specified in Sec. 63.5490(d), or a reconstructed affected 
source, as specified in Sec. 63.5490(e), must be in compliance with 
this subpart upon becoming a major source.
    (2) An area source that meets the criteria of an existing affected 
source, as specified in Sec. 63.5490(f), must be in compliance with 
this subpart no later than 3 years after it becomes a major source.
    (d) You must meet the notification requirements in Sec. 63.5575 and 
in subpart A of this part. Some of the notifications must be submitted 
before you are required to comply with the emission limits, operating 
limits, and work practice standards in this subpart.
    (e) For the purposes of this subpart, the compliance dates in this 
section supersede the compliance dates in subparts F, G, H, U and UU of 
this part.

Emission Limits, Operating Limits, and Work Practice Standards


Sec. 63.5505  What emission limits, operating limits, and work practice 
standards must I meet?

    (a) You must meet each emission limit and work practice standard in 
Table 1 to this subpart that applies to you.

mean ``daily averages during the compliance demonstration'' for 
purposes of this subpart.
    (2) For batch process vents, establish your site-specific operating 
limit using the procedures in Sec. 63.505(b)(3), except that, if you 
demonstrate initial compliance using a month-long compliance 
demonstration, references to ``compliance testing'' and ``performance 
test'' mean ``compliance demonstration'' for purposes of this subpart.
    (3) For condensers, record the outlet (product side) gas or 
condensed liquid temperature averaged over the same period as the 
compliance demonstration while the vent stream is routed and 
constituted normally. Locate the temperature sensor in a position that

any cooling cycle(s)). Record the operating time since the end of the 
last carbon bed regeneration cycle and the beginning of the next carbon 
bed regeneration cycle during the period of the compliance 
demonstration. Locate the temperature and flow sensors in positions 
that provide representative measurement of these parameters.
    (10) For oil absorbers, record the flow of absorption liquid 
through the absorber, the temperatures of the absorption liquid before

continuous compliance (as specified in Tables 5 and 6 to this subpart) 
with each emission limit, each operating limit, and each work practice 
standard that apply to you. This includes periods of startup, shutdown, 
and malfunction. These instances are deviations from the emission 
limits, operating limits, and work practice standards in this subpart. 
These deviations must be reported

[[Page 40060]]

according to the requirements in Sec. 63.5580.
    (c) During periods of startup, shutdown, and malfunction, you must 
operate according to the SSM plan.
    (d) Consistent with Secs. 63.6(e) and 63.7(e)(1), deviations that 
occur during a period of startup, shutdown, or malfunction are not 
violations if you demonstrate to the Administrator's satisfaction that 
you were operating according to the SSM plan.


Sec. 63.5560  How do I monitor and collect data to demonstrate 
continuous compliance?

    (a) You must monitor and collect data according to this section.
    (b) Except for monitor malfunctions, associated repairs, and 
required quality assurance or control activities (including, as 
applicable, calibration checks and required zero and span adjustments), 
you must monitor continuously (or collect data at all required 
intervals) at all times that the affected source is operating, 
including periods of startup, shutdown, and malfunction.
    (c) You may not use data recorded during monitoring malfunctions, 
associated repairs, required quality assurance or control activities, 
and periods of no flow for all or a portion of an affected source in 
data averages and calculations used to report emission or operating 
levels, nor may such data be used in fulfilling a minimum data 
availability requirement, if applicable. You must use all the data 
collected during all other periods in assessing the operation of the 
control device and associated control system.
    (d) All terms in this subpart that define a period of time for 
completing required tasks (e.g., weekly, monthly, quarterly, or 
annually) refer to the standard calendar periods.
    (1) You may change time periods specified in this subpart for 
completing required tasks by mutual agreement with the Administrator, 
as specified in subpart A of this part. For example, a period could 
begin on the compliance date or another date, rather than on the first 
day of the standard calendar period. For each time period that is 
changed by agreement, the revised period must remain in effect until it 
is changed. A new request is not necessary for each recurring period.
    (2) Where the period specified for compliance is a standard 
calendar period, if the initial compliance date occurs after the 
beginning of the period, then you must comply according to the schedule 
specified in paragraph (d)(2)(i) or (ii) of this section, as 
appropriate.
    (i) You must comply before the end of the standard calendar period 
within which the compliance deadline occurs, if there remain at least 3 
days for tasks that must be performed weekly, at least 2 weeks for 
tasks that must be performed monthly, at least 1 month for tasks that 
must be performed quarterly, or at least 3 months for tasks that must 
be performed annually; or
    (ii) In all instances where a provision of this subpart requires 
completing a task during each of multiple successive periods, you may 
perform the required task at any time during the specified period, 
provided that the task is conducted at a reasonable interval after 
completion of the task during the previous period.
