National Emission Standards for Hazardous Air Pollutants: Paper 
and Other Web Coating Residual Risk and Technology Review

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: This action finalizes the residual risk and technology review 
(RTR) conducted for the Paper and Other Web Coating (POWC) source 
category regulated under national emission standards for hazardous air 
pollutants (NESHAP). The Agency is finalizing the proposed 
determination that risks due to emissions of air toxics are acceptable 
from this source category and that the current NESHAP provides an ample 
margin of safety to protect public health. Further, the U.S. 
Environmental Protection Agency (EPA) identified no new cost-effective 
controls under the technology review that would achieve significant 
further emissions reductions, and, thus, is finalizing the proposed 
determination that no revisions to the standards are necessary based on 
developments in practices, processes, or control technologies. In 
addition, the Agency is taking final action addressing startup, 
shutdown, and malfunction (SSM). These final amendments address 
emissions during SSM events, add a compliance demonstration equation 
that accounts for retained volatiles in the coated web; add repeat 
testing and electronic reporting requirements; and make technical and 
editorial changes. The EPA is making these amendments to improve the 
effectiveness of the NESHAP, and although these amendments are not 
expected to reduce emissions of hazardous air pollutants (HAP), they 
will improve monitoring, compliance, and implementation of the rule.

DATES: This final rule is effective on July 9, 2020. The incorporation 
by reference (IBR) of certain publications listed in the rule is 
approved by the Director of the Federal Register as of July 9, 2020. 
The IBR of certain other publications listed in the rule is approved by 
the Director of the Federal Register as of December 4, 2002.

C. Judicial Review and Administrative Reconsideration

    Under Clean Air Act (CAA) section 307(b)(1), judicial review of 
this final action is available only by filing a petition for review in 
the United States Court of Appeals for the District of Columbia Circuit 
(the Court) by September 8, 2020. Under CAA section 307(b)(2), the 
requirements established by this final rule may not be challenged 
separately in any civil or criminal proceedings brought by the EPA to 
enforce the requirements.
    Section 307(d)(7)(B) of the CAA further provides that only an 
objection to a rule or procedure which was raised with reasonable 
specificity during the period for public comment (including any public 
hearing) may be raised during judicial review. This section also 
provides a mechanism for the EPA to reconsider the rule if the person 
raising an objection can demonstrate to the Administrator that it was 
impracticable to raise such objection within the period for public 
comment or if the grounds for such objection arose after the period for 
public comment (but within the time specified for judicial review) and 
if such objection is of central relevance to the outcome of the rule. 
Any person seeking to make such a demonstration should submit a 
Petition for Reconsideration to the Office of the Administrator, U.S. 
EPA, Room 3000, WJC South Building, 1200 Pennsylvania Ave. NW, 
Washington, DC 20460, with a copy to both the person(s) listed in the

General Counsel for the Air and Radiation Law Office, Office of General 
Counsel (Mail Code 2344A), U.S. EPA, 1200 Pennsylvania Ave. NW, 
Washington, DC 20460.

II. Background

A. What is the statutory authority for this action?

    Section 112 of the CAA establishes a two-stage regulatory process 
to address emissions of HAP from stationary sources. In the first 
stage, the Agency must identify categories of sources emitting one or 
more of the HAP listed in CAA section 112(b) and then promulgate 
technology-based NESHAP for those sources. ``Major sources'' are those 
that emit, or have the potential to emit, any single HAP at a rate of 
10 tons per year (tpy) or more, or 25 tpy or more of any combination of 
HAP. For major sources, these standards are commonly

[[Page 41278]]

referred to as maximum achievable control technology (MACT) standards 
and must reflect the maximum degree of emission reductions of HAP 
achievable (after considering cost, energy requirements, and non-air 
quality health and environmental impacts). In developing MACT 
standards, CAA section 112(d)(2) directs the EPA to consider the 
application of measures, processes, methods, systems, or techniques, 
including, but not limited to, those that reduce the volume of or 
eliminate HAP emissions through process changes, substitution of 
materials, or other modifications; enclose systems or processes to 
eliminate emissions; collect, capture, or treat HAP when released from 
a process, stack, storage, or fugitive emissions point; are design, 
equipment, work practice, or operational standards; or any combination 
of the above.
    For these MACT standards, the statute specifies certain minimum 
stringency requirements, which are referred to as MACT floor 
requirements, and which may not be based on cost considerations. See 
CAA section 112(d)(3). For new sources, the MACT floor cannot be less 
stringent than the emission control achieved in practice by the best-
controlled similar source. The MACT standards for existing sources can 
be less stringent than floors 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 
standards, the Agency must also consider control options that are more 
stringent than the floor under CAA section 112(d)(2). The EPA may 
establish standards more stringent than the floor, based on the 
consideration of the cost of achieving the emissions reductions, any 
non-air quality health and environmental impacts, and energy 
requirements.
    In the second stage of the regulatory process, the CAA requires the 
EPA to undertake two different analyses, which we refer to as the 
technology review and the residual risk review. Under the technology 
review, the EPA must review the technology-based standards and revise 
them ``as necessary (taking into account developments in practices, 
processes, and control technologies)'' no less frequently than every 8 
years, pursuant to CAA section 112(d)(6). Under the residual risk 
review, the EPA must evaluate the risk to public health remaining after 
application of the technology-based standards and revise the standards, 
if necessary, to provide an ample margin of safety to protect public 
health or to prevent, taking into consideration costs, energy, safety, 
and other relevant factors, an adverse environmental effect. The 
residual risk review is required within 8 years after promulgation of 
the technology-based standards, pursuant to CAA section 112(f). In 
conducting the residual risk review, if the EPA determines that the 
current standards provide an ample margin of safety to protect public 
health, it is not necessary to revise the MACT standards pursuant to 
CAA section 112(f).\1\ For more information on the statutory authority 
for this rule, see 84 FR 49382 (September 19, 2019).
---------------------------------------------------------------------------

    \1\ The Court has affirmed this approach of implementing CAA 
section 112(f)(2)(A): NRDC v. EPA, 529 F.3d 1077, 1083 (DC Cir. 
2008) (``If EPA determines that the existing technology-based 
standards provide an `ample margin of safety,' then the Agency is 
free to readopt those standards during the residual risk 
rulemaking.'').
---------------------------------------------------------------------------

B. What is the POWC source category and how does the NESHAP regulate 
HAP emissions From the source category?

    The EPA promulgated the POWC NESHAP on December 4, 2002 (67 FR 
72330). The standards are codified at 40 CFR part 63, subpart JJJJ. The 
POWC source category includes new and existing facilities that coat 
paper and other web substrates that are major sources of HAP emissions. 
For purposes of the regulation, a web is defined as a continuous 
substrate that is capable of being rolled at any point during the 
coating process. Further, a web coating line is any number of work 
stations, of which one or more applies a continuous layer of coating 
material along the entire width of a continuous web substrate or any 
portion of the width of the web substrate, and any associated curing/
drying equipment between an unwind (or feed) station and a rewind (or 
cutting) station. The source category covered by this NESHAP currently 
includes 168 facilities.
    Web coating operations covered by other NESHAP (i.e., Printing and 
Publishing, 40 CFR part 63, subpart KK; Magnetic Tape, 40 CFR part 63, 
subpart EE; Metal Coil Coating, 40 CFR part 63, subpart SSSS; Fabric 
Coating, 40 CFR part 63, subpart OOOO), and research and development 
lines are excluded from the requirements of 40 CFR part 63, subpart 
JJJJ. In addition, specific process exclusions include lithography, 
screen printing, letterpress, and narrow web flexographic printing.
    Facilities subject to the POWC NESHAP utilize low-solvent coatings, 
add-on controls, or a combination of both to meet the organic HAP 
emission limits, as described in the preamble to the proposed rule (84 
FR 49385, September 19, 2019). The NESHAP also includes various 
operating limits, initial and continuous compliance requirements, and 
recordkeeping and reporting requirements for the POWC source category. 
The EPA reviewed these requirements and are updating them as part of 
this action in conjunction with finalizing the RTR for this source 
category

C. What changes did we propose for the POWC source category in our 
September 19, 2019, proposal?

    On September 19, 2019, the EPA published a proposed rule in the 
Federal Register for the POWC NESHAP, 40 CFR part 63, subpart JJJJ, 
that took into consideration the RTR analyses. As discussed in the 
preamble to the proposed rule, the technology review did not identify 
any developments in practices, processes, or control technologies that 
were widely applicable to the industry that would significantly reduce 
HAP emissions, and, therefore, the Agency did not propose any changes 
to the NESHAP based on the technology review. Further, as discussed in 
the preamble to the proposed rule, the risk analysis indicated no 
changes to the NESHAP are necessary to reduce risk to an acceptable 
level, to provide an ample margin of safety to protect public health, 
or to prevent an adverse environmental effect. In addition to and 
separate from the proposed determinations based on our RTR analyses, 
the EPA proposed the following:
     Revisions to the SSM provisions of the NESHAP to ensure 
that they are consistent with the Court decision in Sierra Club v. EPA, 
551 F. 3d 1019 (D.C. Cir. 2008), which vacated two provisions that 
exempted sources from the requirement to comply with otherwise 
applicable CAA section 112(d) emission standards during periods of SSM;
     a new compliance calculation to account for retained 
volatile organic content retained in the coated web;
     new periodic air emissions testing requirements for 
facilities that use non-recovery control devices;
     new reporting provisions requiring affected sources to 
electronically submit initial notifications, notification of compliance 
status, semiannual compliance reports, performance test reports, and 
performance evaluation reports;
     new temperature sensor validation requirements;
     operating parameter clarifications;

[[Page 41279]]

     IBR of several test methods; and
     technical and editorial changes to remove the Occupational 
Safety and Health Administration (OSHA)-defined carcinogens reference, 
clarify compliance demonstration options, clarify the definition of 
coating materials, add a web coating line usage threshold, add a 
printing activity exemption, clarify testing requirements, change 
applicability of sources using only non-HAP coatings, clarify oxidizer 
temperature monitoring compliance, and revise compliance report content 
requirements.

III. What is included in this final rule?

    This action is finalizing the EPA's determinations pursuant to the 
RTR provisions of CAA section 112 for the POWC source category. This 
action is also finalizing other changes to the NESHAP, including 
revisions to the SSM requirements; a compliance calculation to account 
for retained volatile organic content retained in the coated web; 
periodic testing requirements for add-on control devices; electronic 
submittal of initial notifications, notification of compliance status, 
semiannual compliance reports, performance test reports, and 
performance evaluation reports; temperature sensor validation 
requirements; operating parameter clarifications; IBR of several test 
methods; and various technical and editorial changes.

A. What are the final rule amendments based on the risk review for the 
POWC source category?

    The EPA proposed no changes to the POWC NESHAP based on the risk 
review conducted pursuant to CAA section 112(f). The EPA is finalizing 
the proposed determination that risks from the source category are 
acceptable, considering all of the health information and factors 
evaluated, and also considering risk estimation uncertainty. The Agency 
is also finalizing the proposed determination that revisions to the 
current standards are not necessary to reduce risk to an acceptable 
level, to provide an ample margin of safety to protect public health, 
or to prevent an adverse environmental effect. The EPA received no new 
data or other information during the public comment period that 
affected the proposed determinations. Therefore, the EPA is finalizing 
the proposed determination and making no revisions to the NESHAP based 
on the analyses conducted under CAA section 112(f), and we are 
readopting the standards.

B. What are the final rule amendments based on the technology review 
for the POWC source category?

    In the proposed rule, the EPA proposed to determine that there are 
no developments in practices, processes, and control technologies that 
warrant revisions to the MACT standards for this source category. The 
EPA received no new data or other information during the public comment 
period that affected our proposed determinations. Therefore, the EPA is 
finalizing the proposed determination and making no revisions to the 
MACT standards under CAA section 112(d)(6).

C. What are the final rule amendments addressing emissions during 
periods of SSM?

    The EPA proposed amendments to the POWC NESHAP to remove and revise 
provisions related to SSM. The EPA is finalizing the amendments, as 
proposed, with minor clarifications with this rulemaking. In its 2008 
decision in Sierra Club v. EPA, 551 F.3d 1019 (D.C. Cir. 2008), the 
Court vacated portions of two provisions in the EPA's CAA section 112 
regulations governing the emissions of HAP during periods of SSM. 
Specifically, the Court vacated the SSM exemption contained in 40 CFR 
63.6(f)(1) and 40 CFR 63.6(h)(1), holding that under section 302(k) of 
the CAA, emissions standards or limitations must be continuous in 
nature and that the SSM exemption violates the CAA's requirement that 
some CAA section 112 standards apply continuously. As detailed in 
section IV.D of the preamble to the proposed rule (84 FR 49382, 
September 19, 2019), the amended POWC NESHAP requires that the 
standards apply at all times (see 40 CFR 63.3320(b)), consistent with 
the Court decision in Sierra Club v. EPA, 551 F.3d 1019 (D.C. Cir. 
2008). In addition to eliminating the SSM exemption, the EPA has 
removed the requirement for sources to develop and maintain an SSM 
plan, as well as certain recordkeeping and reporting provisions related 
to the SSM exemption.
    The EPA is finalizing the SSM provisions as proposed without 
setting a separate standard for startup and shutdown as discussed in 
the preamble to the proposed rule in section IV.D. Further, the EPA is 
not finalizing standards for malfunctions. As discussed in the 
September 19, 2019, proposal, the EPA interprets CAA section 112 as not 
requiring emissions that occur during periods of malfunction to be 
factored into development of CAA section 112 standards, although the 
EPA has the discretion to set standards for malfunctions where 
feasible. For this action, it is unlikely that a malfunction would 
result in a violation of the standards, and no comments were submitted 
that would suggest otherwise. Refer to section IV.D of the preamble to 
the proposed rule for further discussion of the EPA's rationale for the 
decision not to set standards for malfunctions, as well as a discussion 
of the actions a source could take in the unlikely event that a source 
fails to comply with the applicable CAA section 112(d) standards as a 
result of a malfunction event.
    As explained in more detail below, the EPA is finalizing revisions 
to the General Provisions table to 40 CFR part 63, subpart JJJJ, to 
eliminate requirements that include rule language providing an 
exemption for periods of SSM. Additionally, the EPA is finalizing our 
proposal to eliminate language related to SSM that treats periods of 
startup and shutdown the same as periods of malfunction, as explained 
further below. Finally, the EPA is finalizing the proposed amendments 
to revise the reporting and recordkeeping requirements as they relate 
to malfunctions, as further described below. As discussed in the 
preamble to the proposed rule, these revisions are consistent with the 
requirement in 40 CFR 63.3320(b) that the standards apply at all times. 
Refer to sections IV.C of this preamble for a detailed discussion of 
these amendments.

D. What other changes have been made to the NESHAP?

    Other changes that have been made to the regulation include 
incorporation of a compliance calculation to account for retained 
volatile organic content retained in the coated web; periodic 
performance testing requirements; electronic submittal of initial 
notifications, notification of compliance status, semiannual compliance 
reports, performance test reports, and performance evaluation reports; 
temperature sensor validation requirements; operating parameter 
clarifications; IBR of several test methods; and various technical and 
editorial changes. The EPA's analyses and changes related to these 
issues are discussed below.
    Other changes to the NESHAP that do not fall into the categories in 
the previous section include:
     Method for determining volatile organic matter retained in 
the coated web. The EPA is finalizing the addition of an equation to 
account for volatile organic matter retained in the coated

[[Page 41280]]

web as discussed in section IV.D of this preamble.
     Periodic performance testing. The EPA is finalizing a 
periodic testing requirement for non-recovery add-on control devices to 
ensure continued compliance, as discussed in section IV.E of this 
preamble.
     Electronic reporting. The EPA is finalizing amendments to 
the reporting requirements to require electronic reporting for initial 
notifications, notifications of compliance status, semiannual 
compliance reports, performance test reports, and performance 
evaluation reports, as discussed in section IV.F of this preamble.
     Temperature sensor validation. The EPA is finalizing 
amendments to remove the temperature sensor calibration requirement and 
replace it with validation requirements to ensure continued compliance, 
as discussed in section IV.G of this preamble.
     Operating parameter clarification. The EPA is finalizing, 
as proposed, an operating parameter clarification, as discussed in 
section IV.H of this preamble.
     IBR under 1 CFR part 51. The EPA is finalizing the IBR of 
several test methods, as discussed in section IV.I of this preamble.
     Technical and editorial changes. The EPA is finalizing 
technical and editorial changes, as discussed in section IV.J of this 
preamble.

E. What are the effective and compliance dates of the standards?

    The revisions to the NESHAP being promulgated in this action are 
effective on July 9, 2020.\2\ The compliance date for affected existing 
facilities is 365 days after the effective date of the final rule, with 
the exception of electronic reporting of semiannual reports. Affected 
source owners and operators that commence construction or 
reconstruction after September 19, 2019, must comply with all 
requirements of the subpart, including the amendments being finalized 
with this action (except for the electronic reporting of semiannual 
reports), no later than the effective date of the final rule or upon 
startup, whichever is later. All affected sources must use the 
Compliance and Emissions Data Reporting Interface (CEDRI) reporting 
template for semiannual reports for the subsequent semiannual reporting 
period after the form has been available in CEDRI for 1 year. All 
affected existing facilities must meet the current requirements of 40 
CFR part 63, subpart JJJJ until the applicable compliance date of the 
amended rule.
---------------------------------------------------------------------------

    \2\ This final action is not a ``major rule'' as defined by 5 
U.S.C. 804(2), so the effective date of the final rule is the 
promulgation date as specified in CAA section 112(d)(10).
---------------------------------------------------------------------------

    As explained in the preamble to the proposed rule, the EPA proposed 
a compliance period of 180 days for existing sources because the 
amendments would impact ongoing compliance requirements (84 FR 79406, 
September 19, 2019). Two significant amendments, the removal of the SSM 
exemption and the addition of electronic reporting, were determined to 
require additional time for changing reporting and recordkeeping 
systems. As stated in the preamble to the proposed rule, the EPA's 
experience with similar industries that are required to convert 
reporting mechanisms; install necessary hardware and software; become 
familiar with the process of submitting performance test results 
electronically through the EPA's CEDRI; test these new electronic 
submission capabilities; reliably employ electronic reporting; and 
convert logistics of reporting processes to different time-reporting 
parameters, shows that a time period of a minimum of 90 days, and more 
typically, 180 days, is generally necessary to successfully complete 
these changes. Our experience with similar industries further shows 
that owners or operators of this sort of regulated facility generally 
requires a time period of 180 days to read and understand the amended 
rule requirements; evaluate their operations to ensure that they can 
meet the standards during periods of startup and shutdown as defined in 
the rule, and make any necessary adjustments; adjust parameter 
monitoring and recording systems to accommodate revisions; and update 
their operations to reflect the revised requirements. The EPA 
recognizes the confusion that multiple compliance dates for individual 
requirements would create and the additional burden such an assortment 
of dates would impose.
    In the preamble to the proposed rule, the EPA solicited comment on 
whether the 180-day compliance period was reasonable and specifically 
requested sources provide information regarding the specific actions 
they would need to undertake to comply with the amended rule. The EPA 
also noted that information provided in response to this request for 
comment could result in changes to the proposed compliance date (84 FR 
49406, September 19, 2019). Comments were provided suggesting that 180 
days was not enough time to comply with the proposed changes and that a 
minimum of 365 days was needed. Commenters noted that tasks that would 
need to be completed during the compliance period were: Develop site-
specific implementation plan for changes to add-on control device 
requirements; review startup and shutdown procedures; reprogram 
electronic systems and automated alarms consistent with the removal of 
the SSM provisions; revise the oxidizer temperature operating limit; 
rework recordkeeping and reporting procedures and systems to match the 
new CEDRI form; develop and communicate guidance to ensure consistent 
implementation across a company's facilities; prepare permit 
applications; acquire new permits; and develop and provide training for 
facility staff on the amended requirements.
    The EPA reviewed the information provided by commenters regarding 
tasks needed to be completed during the compliance period and agrees 
that 180 days is not sufficient time, particularly for implementing the 
changes to add-on control device requirements and for reworking 
recordkeeping and reporting procedures to comply with the amendments, 
including the removal of the SSM exemption. This source category needs 
additional time for these changes because of the complexity of the 
compliance calculations and the potential for a large variety of 
products to be produced on the same equipment (which requires multiple 
startup and shutdown events on a regular basis). From our assessment of 
the time frame needed for compliance with the entirety of the revised 
requirements and considering the public comments received, the EPA 
considers a period of 365 days to be the most expeditious compliance 
period practicable for the POWC source category, and, thus, the EPA is 
finalizing that existing affected sources must be in compliance with 
all of the POWC NESHAP amended requirements within 365 days of the 
effective date.
    Additionally, comments were received from multiple commenters 
requesting more time to develop and train on the CEDRI semiannual 
reporting template. The Agency agrees with the commenters that more 
time is needed to accurately develop the template and to train facility 
staff on its use. As such, the EPA is finalizing that the electronic 
reporting template is not required to be used for semiannual reports 
until it has been available in CEDRI for 1 year. To prevent two 
separate reports for one semiannual reporting period, the Agency is 
finalizing that the reporting template should be used for the first 
full semiannual reporting period after the template has been available 
in CEDRI for 1 year. For example, if the template

[[Page 41281]]

becomes available in CEDRI on March 13, 2020, it would be used 
beginning with the report submitted for the July 2021-December 2021 
reporting period.

IV. What is the rationale for our final decisions and amendments for 
the POWC source category?

    For each issue, this section provides a description of what the EPA 
proposed and what the EPA is finalizing for the issue, a summary of key 
comments and responses, and the EPA's rationale for the final decisions 
and amendments. For all comments not discussed in this preamble, 
comment summaries and the EPA's responses can be found in the comment 
summary and response document available in the docket (Docket ID No. 
EPA-HQ-OAR-2018-0416).

A. Residual Risk Review for the POWC Source Category

1. What did we propose pursuant to CAA section 112(f) for the POWC 
source category?
    A residual risk analysis was conducted for the POWC source 
category. Details of the risk analysis can be found in section IV of 
the preamble to the proposed rule (84 FR 49382, September 19, 2019). 
The results of the risk analyses, and decisions on risk acceptability 
and ample margin of safety, as well as the results of the environmental 
risk screening assessment, are summarized here.
    For the POWC source category risk assessment conducted prior to 
proposal, the EPA estimated risks based on actual and allowable 
emissions from POWC surface coating operations. The risk results for 
the POWC source category indicate that both the actual and allowable 
inhalation cancer risks to the individual most exposed are at least 14 
times below the presumptive limit of acceptability of 100-in-1 million 
(i.e., 1-in-10 thousand). The residual risk assessment for the POWC 
source category \3\ estimated cancer incidence rate at 0.005 cases per 
year based on actual emissions. Approximately 4,300 people are exposed 
to a cancer risk equal to or above 1-in-1 million from the source 
category based upon actual emissions from 11 facilities.
---------------------------------------------------------------------------

    \3\ Residual Risk Assessment for the Paper and Other Web Coating 
Source Category in Support of the 2020 Risk and Technology Review 
Final Rule, Docket ID No. EPA-HQ-OAR-2018-0416.
---------------------------------------------------------------------------

    The maximum chronic noncancer target organ-specific hazard index 
(TOSHI) due to inhalation exposures is less than 1 for actual and 
allowable emissions. The results of the acute screening analysis show 
that acute risks are below a level of concern for the source category 
considering the conservative assumptions used that err on the side of 
overestimating acute risk.
    Multipathway screen values are below a level of concern for both 
carcinogenic and non-carcinogenic persistent and bioaccumulative HAP as 
well as emissions of lead compounds. Maximum cancer and noncancer risks 
due to ingestion exposures using health-protective risk screening 
assumptions are below the presumptive limit of acceptability. The 
maximum estimated excess cancer risk is below 1-in-1 million and the 
maximum noncancer hazard quotient (HQ) for mercury is less than 1 based 
upon the Tier 1 farmer/fisher exposure scenario.
    The risk assessment for the POWC source category is contained in 
the report titled Residual Risk Assessment for the Paper and Other Web 
Coating Source Category in Support of the 2020 Risk and Technology 
Review Final Rule, which can be found in the docket for this action 
(Docket ID No. EPA-HQ-OAR-2018-0416).
2. How did the risk review change for the POWC source category?
    Neither the risk assessment nor the Agency's determinations 
regarding risk acceptability, ample margin of safety, or adverse 
environmental effects for the POWC source category have changed since 
the proposal was published on September 19, 2019. Therefore, the EPA is 
finalizing the risk review as proposed with no changes (84 FR 49398, 
September 19, 2019).
3. What key comments did we receive on the risk review, and what are 
our responses?
    Comments were received regarding the risk assessment inputs the EPA 
used to conduct the POWC source category risk assessment. First, 
commenters noted that the acute emissions multipliers should be less 
than the value of 10 that the EPA used in its source category acute 
risk assessment. The EPA agrees with the commenters that an acute 
hourly multiplier of 10 likely over-estimates the emissions for this 
source category, however, we did not reanalyze acute risk for this 
final rulemaking because the risk values were already deemed acceptable 
using the multiplier of 10 for the proposal and would have been further 
reduced with a lower multiplier. Second, commenters noted that the 
EPA's risk assessment was ``very conservative and likely overstates 
both annual and short-term HAP emission rates'' because it used 
allowable emissions as actual emissions where no other data were 
available. The commenters are correct in their assessment that the EPA 
used allowable emissions as actual emissions when no other data were 
available to ensure that the risk analysis did not underestimate the 
risk posed by the source category. Because risk was acceptable using 
this conservative approach and would have been reduced further if 
actual emissions data had been available, the results of this approach 
further supports the EPA's conclusion.
    Additionally, comments were received regarding the risk assessment 
methods the EPA used to conduct the POWC source category risk 
assessment. Two commenters stated that the formaldehyde health value 
used in the risk assessment was not based on the best available 
science, and that the EPA should have used the value from the Chemical 
Industry Institute of Technology (CIIT) biologically-based dose-
response model. We disagree with the commenters that the EPA should 
have used the CIIT formaldehyde value because the EPA has a tiered 
prioritized list of appropriate health benchmark values for use in the 
residual risk assessment, and in general, the hierarchy places greater 
weight on the EPA-derived health benchmarks than those from other 
organizations. Even though the commenters claim the Integrated Risk 
Information System (IRIS) value the EPA used was too high (i.e., the 
value over-estimated risk), the EPA proposed, and is finalizing, that 
the risks from formaldehyde from this source category are acceptable.
    Comments were also received supporting the EPA's use of the 99th 
percentile concentration for modeling acute risk. Overall, the EPA 
received no comments or new information demonstrating a need for the 
Agency to reanalyze risk for the final rulemaking, and, therefore, the 
risk assessment conducted for the proposed rule was used to support the 
Agency's conclusions for the final rule.
    Additionally, the EPA received several comments supporting our 
conclusions relating to risk acceptability and that additional 
emissions reductions are not necessary to provide an ample margin of 
safety. One commenter opposed our acceptability determination because 
the EPA did not consider risk from emission sources from other source 
categories. The EPA has the discretion to conduct a facility-wide risk 
assessment which factors in emissions from process equipment outside of 
the source category. The Agency examines facility-wide risks to provide 
additional context for the source category risks. The development of 
facility-wide risk estimates provides

[[Page 41282]]

additional information about the potential cumulative risks in the 
vicinity of the source category emission units as one means of 
informing potential risk-based decisions about the source category in 
question. The Agency recognizes that, because these risk estimates were 
derived from facility-wide emission estimates which have not generally 
been subjected to the same level of engineering review as the source 
category emission estimates, they may be less certain than our risk 
estimates for the source category in question, but they remain 
important for providing context as long as their uncertainty is taken 
into consideration in the process.
    For detailed comment summaries regarding the residual risk review 
and the corresponding responses, see the memorandum in the docket, 
National Emission Standards for Hazardous Air Pollutants: Paper and 
Other Web Coating (40 CFR part 63, subpart JJJJ) Residual Risk and 
Technology Review, Final Amendments--Response to Public Comments on 
September 19, 2019 Proposal.
4. What is the rationale for our final approach and final decisions for 
the risk review?
    As noted in our proposal, the EPA sets standards under CAA section 
112(f)(2) using ``a two-step standard-setting approach, with an 
analytical first step to determine an `acceptable risk' that considers 
all health information, including risk estimation uncertainty, and 
includes a presumptive limit on maximum individual risk (MIR) of 
`approximately 1-in-10 thousand''' (see 54 FR 38045, September 14, 
1989). The EPA weighs all health risk factors in our risk acceptability 
determination, including the cancer MIR, cancer incidence, the maximum 
TOSHI, the maximum acute noncancer HQ, the extent of noncancer risks, 
the distribution of cancer and noncancer risks in the exposed 
population, and the risk estimation uncertainties.
    The EPA evaluated all of the comments on the risk review and 
determined that no changes to the review are needed. For the reasons 
explained in the proposal, the EPA determined that the risks from the 
POWC source category are acceptable, and the current standards provide 
an ample margin of safety to protect public health and prevent an 
adverse environmental effect. Therefore, pursuant to CAA section 
112(f)(2), the EPA is finalizing the residual risk review as proposed.

B. Technology Review for the POWC Source Category

1. What did we propose pursuant to CAA section 112(d)(6) for the POWC 
source category?
    Pursuant to CAA section 112(d)(6), the EPA proposed to conclude 
that no revisions to the current MACT standards for the POWC source 
category are necessary (84 FR 49382, September 19, 2019). As described 
in section III.B of the preamble to the proposed rule, the technology 
review focused on identifying developments in practices, processes, and 
control technologies for reduction of HAP emissions from POWC 
facilities. In conducting the technology review, the EPA searched for 
and reviewed information on practices, processes, and control 
technologies that were not considered during the development of the 
POWC NESHAP. The review included a search of the Reasonably Available 
Control Technology/Best Available Control Technology/Lowest Achievable 
Emission Rate (RACT/BACT/LAER) Clearinghouse database, reviews of title 
V permits for POWC facilities, site visits to facilities with POWC 
operations, and a review of relevant literature. We did not identify 
any developments in practices, processes, or control technologies that 
were widely applicable to the industry and would significantly reduce 
HAP emissions, and, therefore, the EPA did not propose any changes to 
the NESHAP based on the technology review. For more details on the 
technology review, see the Technology Review Analysis for the Paper and 
Other Web Coating Source Category memorandum, in the docket for this 
rulemaking (Docket ID Item No. EPA-HQ-OAR-2018-0416-0086).
2. How did the technology review change for the POWC source category?
    No new information was received to change the Agency's conclusions 
with respect to the technology review since the proposal was published 
on September 19, 2019. Therefore, the EPA is finalizing the proposed 
determination that no revisions to the NESHAP are necessary pursuant to 
CAA section 112(d)(6).
3. What key comments did we receive on the technology review, and what 
are our responses?
    The EPA received no comments that identified improved control 
technology, work practices, operational procedures, process changes, or 
pollution prevention approaches to reduce emissions in the category 
since promulgation of the current NESHAP. The EPA received multiple 
supportive comments on the proposed technology review. For detailed 
comment summaries regarding the technology review and the corresponding 
responses, see the memorandum in the docket, National Emission 
Standards for Hazardous Air Pollutants: Paper and Other Web Coating (40 
CFR part 63, subpart JJJJ) Residual Risk and Technology Review, Final 
Amendments--Response to Public Comments on September 19, 2019 Proposal.
4. What is the rationale for our final approach for the technology 
review?
    The technology review did not identify any changes in practices, 
processes, or control technologies that would reduce emissions in this 
category. The EPA did not identify any control equipment not previously 
identified; improvements to existing controls; work practices, process 
changes, or operational procedures not previously considered; or any 
new pollution prevention alternatives for this source category. We 
evaluated all of the comments on the technology review and determined 
that no changes to the review are needed, therefore, the EPA is 
finalizing the determination that no revisions to the NESHAP are 
necessary pursuant to CAA section 112(d)(6). Additional details of our 
technology review can be found in the memorandum titled Technology 
Review Analysis for the Paper and Other Web Coating Source Category, in 
the docket for this rulemaking (Docket ID Item No. EPA-HQ-OAR-2018-
0416-0086).

C. Revisions to the SSM Provisions for the POWC Source Category

1. What did we propose pursuant to SSM provisions for the POWC source 
category?
    The EPA proposed amendments to the POWC NESHAP to remove provisions 
related to SSM that are not consistent with the requirement that the 
standards apply at all times. More information concerning the 
elimination of SSM provisions is in the preamble to the proposed rule 
(84 FR 49399-49402, September 19, 2019).
2. How did the revisions to the SSM provisions change for the POWC 
source category?
    The EPA is finalizing the SSM provisions as proposed with no 
changes.
3. What key comments did we receive on the SSM provisions, and what are 
our responses?
    The EPA received several comments related to the proposed removal 
of the

[[Page 41283]]

SSM provisions. One commenter believed that the EPA is not required to 
change the regulation to require sources to meet the emission standards 
at all times, including periods of SSM. The EPA disagrees with the 
commenter's assertion. The EPA believes the Sierra Club decision 
(Sierra Club v. EPA, 551 F.3d 1019) held that emission limitations 
under CAA section 112 must apply continuously and meet minimum 
stringency requirements, even during periods of SSM. Consistent with 
this reading, the EPA proposed to remove the SSM exemption, and is 
finalizing the removal with this action. Other commenters were 
generally supportive of the SSM exemption removal and noted that it 
would likely have minimal impacts on regulated facilities. For detailed 
comment summaries regarding the removal of the SSM exemption and the 
corresponding responses, see the memorandum in the docket, National 
Emission Standards for Hazardous Air Pollutants: Paper and Other Web 
Coating (40 CFR part 63, subpart JJJJ) Residual Risk and Technology 
Review, Final Amendments--Response to Public Comments on September 19, 
2019 Proposal.
4. What is the rationale for our final approach and final decisions for 
the revisions to the SSM provisions?
    The rationale for each of the amendments the EPA is finalizing to 
address SSM is in the preamble to the proposed rule (84 FR 49399-49402, 
September 19, 2019). After evaluation of the comments received, the 
EPA's rationale for revisions to the SSM provisions has not changed 
since proposal and we are finalizing the approach for removing the SSM 
provisions as proposed.

D. Method for Determining Volatile Organic Matter Retained in the 
Coated Web

1. What did we propose?
    A portion of the HAP in coatings applied to paper and other web 
substrates may be retained in the web instead of being volatilized as 
air emissions. The existing NESHAP allows for the accounting of HAP 
retained in the coated web in 40 CFR 63.3360(g), but stakeholders 
indicated the requirement to ``develop a testing protocol to determine 
the mass of volatile matter retained . . . and submit this protocol to 
the Administrator for approval'' was vague and unworkable. As discussed 
in the preamble to the proposed rule (84 FR 49402, September 19, 2019), 
to provide clarity and reduce regulatory burden, the EPA proposed to 
incorporate the utilization of an emission factor to account for 
volatile organic matter retained in the coated web. As discussed in the 
preamble to the proposed rule, the EPA proposed new language to allow 
facilities to account for retained volatile organics in their 
compliance demonstration calculations without requiring the submittal 
of an alternative monitoring request to the EPA under the provisions of 
40 CFR 63.8(f).
2. What changed since proposal?
    Two changes have been made to the proposed provisions for 
determining volatile organic matter retained in the coated web. First, 
the EPA has clarified that ``retained in the web'' means ``retained in 
the coated web or otherwise not emitted.'' Second, the EPA has added 
additional flexibility to allow any EPA-approved method, manufacturer's 
emissions test data, or mass balance approach using modified EPA Method 
24 to be used to develop the emission factor.
3. What are the key comments and what are our responses?
    The EPA received comments from four commenters supporting the 
addition of the emission factor approach for determining the amount of 
volatile matter retained in the web. Commenters suggested that the EPA 
clarify that ``retained in the web'' means ``retained in the coated web 
or otherwise not emitted.'' The EPA agrees that this is an appropriate 
clarification and has revised the regulatory text accordingly.
    The EPA also received comments suggesting that we allow other 
methods for developing the emission factor to determine the amount of 
volatile organic matter retained. Commenters specifically requested the 
ability to use other EPA-approved test methods, manufacturer's 
emissions test data, or mass-balance type approaches using modified EPA 
Method 24. The EPA agrees that allowing the use of these methods would 
provide flexibility and still appropriately characterize emissions from 
the web coating process.
    For detailed comment summaries regarding the methods used to 
determine the volatile organic matter retained in the coated web and 
the corresponding responses, see the memorandum in the docket, National 
Emission Standards for Hazardous Air Pollutants: Paper and Other Web 
Coating (40 CFR part 63, subpart JJJJ) Residual Risk and Technology 
Review, Final Amendments--Response to Public Comments on September 19, 
2019 Proposal.
4. What is the rationale for our final approach to determining volatile 
matter retained in the coated web?
    The EPA reviewed the public comments and are finalizing the 
proposed method of determining the volatile organic material retained 
in the coated web with two changes as a result of public comment. The 
EPA is clarifying that ``retained in the web'' means ``retained in the 
coated web or otherwise not emitted'' in the regulatory text and is 
allowing for additional test methods for use in the development of the 
emission factor. Both of these changes provide regulatory clarity and 
flexibility, but still appropriately characterize emissions from the 
web coating process. The amendments add compliance flexibility and 
reduce regulatory burden but do not alter the emission standard. This 
approach quantifies emissions in a way that is representative of the 
actual emissions from the coating operations instead of assuming that 
all coating-HAP is emitted.

E. Periodic Performance Testing

1. What did we propose?
    The EPA proposed that facilities that use non-recovery control 
devices (e.g., thermal and catalytic oxidizers) must conduct periodic 
air emissions performance testing, with the first of the periodic 
performance tests to be conducted within 3 years of the effective date 
of the revised standards and thereafter every 5 years following the 
previous test. The EPA also proposed that facilities using the emission 
factor approach to account for volatile matter retained in the web must 
conduct periodic performance testing every 5 years to re-establish the 
emission factor.
2. What changed since proposal?
    The periodic performance testing requirements for catalytic 
oxidizers and those for emission factor development have changed since 
the September 2019 proposal in response to public comment. For 
catalytic oxidizers, commenters suggested that annual catalyst activity 
testing would be more indicative of oxidizer operation than 5-year 
inlet/outlet emissions testing. The EPA is therefore finalizing that 
catalytic oxidizers may do an annual catalyst activity test instead of 
the 5-year inlet/outlet emissions testing. The EPA is finalizing 
periodic performance testing requirements for thermal oxidizers as 
proposed (84 FR 49403, September 19, 2019). The EPA has clarified that 
the testing is only required for add-on control devices used to 
demonstrate

[[Page 41284]]

compliance with the POWC NESHAP. The EPA is not finalizing the 5-year 
requirement to re-establish emission factors used in determining the 
amount of volatile organics retained in the coated web for 40 CFR 
63.3360(g), but is finalizing a requirement that periodic performance 
testing be done if there is a change in coating formulation, operation 
conditions, or other change that could reasonably result in increased 
emissions since the time of the last test used to establish the 
emission factor.
3. What are the key comments and what are our responses?
    Comments were received both opposing and supporting the proposed 5-
year periodic emissions testing requirements. Commenters that opposed 
the requirements noted that oxidizers are not used continuously in the 
flexible packaging industry but only when compliant coatings are not 
used and stated that testing does not show any evidence of degradation 
in thermal oxidizers. Commenters noted that degradation may occur when 
a catalytic oxidizer is used to control a process using silicon-
containing coatings, but that a catalyst activity test would be more 
appropriate to determine performance. The EPA has reviewed these 
comments and is finalizing repeat emissions performance testing for 
catalytic oxidizers with the alternative to perform an annual catalyst 
activity test. The EPA is finalizing the periodic emissions performance 
test requirements for thermal oxidizers, as proposed. Both requirements 
can be found in 40 CFR 63.3360(a)(2).
    Commenters suggested that periodic performance testing for re-
establishment of emission factors, such as for reactive coatings, is 
not necessary in most cases and would be excessively burdensome and 
unnecessary, except if the product's formulation or its process 
conditions have changed in a way that would increase emissions. The EPA 
has reviewed the commenters concerns and agrees that repeat testing to 
re-establish emission factors for coatings used in the POWC industry 
every 5 years could be burdensome and is not finalizing this 
requirement in this action.
    Commenters requested clarification that the first periodic 
emissions performance test can be conducted within either 3 years of 
promulgation of the final amendments or within 60 months of the 
previous test, whichever is later, to ensure that any facility that has 
recently conducted a performance test will have the full 5 years 
between tests. The EPA intended that performance tests recently 
performed (within 3 years of promulgation of the final amendments) can 
count towards the first periodic testing requirements. Commenters also 
requested clarification if state-required volatile organic compound 
(VOC) performance testing or HAP performance testing performed for 
another MACT can count towards this requirement. The EPA agrees that 
both testing for VOC destruction efficiency and HAP destruction 
efficiency for another subpart are appropriate substitutions for the 
periodic testing requirements in the POWC NESHAP because these tests 
will demonstrate ongoing performance of the control device. Both of 
these issues have been clarified in 40 CFR 63.3330(a)(2).
    Commenters requested clarification that only control devices used 
to demonstrate compliance with the POWC NESHAP would need to be tested, 
and that VOC tests required by the state permitting authority could be 
used to meet the proposed requirements. The EPA agrees with the 
commenters that add-on control devices not used to demonstrate 
compliance with the POWC NESHAP (i.e., those used to demonstrate 
compliance with new source performance standards (NSPS) or state VOC 
requirements) are not required to be tested under the POWC NESHAP 
amendments. The EPA also agrees that VOC tests required by the state 
permitting authority could be used to meet the POWC repeat testing 
requirements. The EPA's proposal was not intended to impose duplicative 
testing requirements. Regulatory text has been amended throughout the 
NESHAP to state that the requirements for add-on control devices are 
only for those used to demonstrate compliance with 40 CFR 63.3320, and 
that VOC tests required by state permitting authorities can be used to 
meet the repeat performance testing requirements.
    For detailed comment summaries regarding the repeat testing 
provisions and the corresponding responses, see the memorandum in the 
docket, National Emission Standards for Hazardous Air Pollutants: Paper 
and Other Web Coating (40 CFR part 63, subpart JJJJ) Residual Risk and 
Technology Review, Final Amendments--Response to Public Comments on 
September 19, 2019 Proposal.
4. What is the rationale for our final approach and final decisions for 
the periodic emissions testing requirement?
    Although ongoing monitoring of operating parameters is required by 
the existing POWC NESHAP, as the control device ages over time, the 
destruction efficiency of the control device can be compromised due to 
various factors. These factors are discussed in more detail in the 
memorandum titled Revised Periodic Testing of Control Devices Used to 
Comply with the Paper and Other Web Coating NESHAP, in the docket for 
this rulemaking (Docket ID No. EPA-HQ-OAR-2018-0416). After considering 
the comments discussed above and based on the need for vigilance in 
maintaining the control device equipment, the EPA is finalizing the 
requirement for periodic testing of thermal oxidizers once every 5 
years and the alternative of annual catalyst activity tests for 
catalytic oxidizers.

F. Electronic Reporting

1. What did we propose?
    The EPA proposed amendments to the POWC NESHAP to require owners 
and operators of POWC facilities to submit electronic copies of 
required performance test reports (40 CFR 63.3400(f)), performance 
evaluation reports (40 CFR 63.3400(g)), initial notifications (40 CFR 
63.3400(b)), notification of compliance status (40 CFR 63.3400(e)), and 
semiannual compliance reports (40 CFR 63.3400(c)) through the EPA's 
Central Data Exchange (CDX) using CEDRI. A description of the 
electronic data submission process is provided in the proposal (at 84 
FR 49403, September 19, 2019) and in the memorandum, Electronic 
Reporting Requirements for New Source Performance Standards (NSPS) and 
National Emission Standards for Hazardous Air Pollutants (NESHAP) 
Rules, Docket ID Item No. EPA-HQ-OAR-2018-0416-0091. The proposed 
amendment replaces the previous rule requirement to submit the 
notifications and reports to the Administrator at the appropriate 
address listed in 40 CFR 63.13. This rule requirement does not affect 
submittals required by state air agencies as required by 40 CFR 63.13.
    For the performance test reports required in 40 CFR 63.3400(f), the 
amendments proposed required that performance test results collected 
using test methods that are supported by the EPA's Electronic Reporting 
Tool (ERT) as listed on the ERT website \4\ at the time of the test be 
submitted in the format generated through the use of the ERT and that 
other performance test results be submitted in portable document format 
(PDF) using the attachment module of the ERT. Similarly, performance 
evaluation results of continuous monitoring systems (CMS)

[[Page 41285]]

measuring relative accuracy test audit pollutants that are supported by 
the ERT at the time of the test must be submitted in the format 
generated through the use of the ERT and other performance evaluation 
results be submitted in PDF using the attachment module of the ERT.
---------------------------------------------------------------------------

    \4\ https://www.epa.gov/electronic-reporting-air-emissions/electronic-reporting-tool-ert.
---------------------------------------------------------------------------

    For the proposed electronic submittal of initial notifications 
required in 40 CFR 63.3400(b), no specific form is available at this 
time, therefore, these notifications are required to be submitted in 
PDF using the attachment module of the ERT. For electronic submittal of 
notifications of compliance status reports required in 40 CFR 
63.3400(e), it was proposed that the final semiannual report template 
discussed above, would also contain the information required for the 
notification of compliance status report.
    For semiannual compliance reports required in 40 CFR 63.3400(c), 
the amendment proposed required that owners and operators use the final 
semiannual report template to submit information to CEDRI. The template 
will reside in CEDRI and was proposed to be used on and after 180 days 
past finalization of the amendments. The proposed template for these 
reports was included in the docket for public comment.\5\
---------------------------------------------------------------------------

    \5\ See POWC_Electronic_Reporting_Template.xlsx, available at 
Docket ID Item No. EPA-HQ-2018-0416-0165.
---------------------------------------------------------------------------

    Additionally, in the proposal, the EPA identified two broad 
circumstances in which electronic reporting extensions may be provided. 
In both circumstances, the decision to accept the claim of needing 
additional time to report is within the discretion of the 
Administrator, and reporting should occur as soon as possible. The EPA 
provided these potential extensions to protect owners and operators 
from noncompliance in cases where they cannot successfully submit a 
report by the reporting deadline for reasons outside of their control.
2. What changed since proposal?
    The EPA has changed the deadline to use the CEDRI semiannual 
reporting template to be 1 year after the template has been available 
in CEDRI, instead of the proposed 180 days after date of publication of 
the final rule. The EPA has also changed the electronic submittal of 
the notification of compliance status to be a PDF instead in the 
semiannual reporting template. No other changes have been made to the 
proposed requirement for owners and operators of POWC facilities to 
submit initial notifications, performance test reports, performance 
evaluation reports, and semiannual reports electronically using CEDRI.
3. What are the key comments and what are our responses?
    The EPA received one comment supporting the proposed amendment to 
require electronic reporting. The commenter, however, believed that the 
proposed force majeure language in 40 CFR 63.3400(j) should be removed 
so there is no exemption from reporting due to force majeure events. As 
explained in detail in the response-to-comments document, 40 CFR 
63.3400(j) does not provide an exemption to reporting, only a method 
for requesting an extension of the reporting deadline. The EPA has 
retained the proposed language in 40 CFR 63.3400(j) for the final rule.
    Commenters expressed concern about potential inconsistencies 
between the POWC electronic reporting requirements and state 
requirements of paper copies of reports for VOC and title V compliance. 
Commenters asked for clarification that the electronic reporting 
requirements replace the POWC title V compliance reporting, including 
timing. The Agency does not agree with the commenter's suggestion 
concerning potential inconsistencies between state requirements for 
paper reporting and federal requirements for VOC and title V permit 
compliance. State requirements developed under the state's own 
authorities are separate and apart from federal requirements developed 
for this rule. As individual federal rules establish applicable 
requirements--including electronic reporting--title V programs bundle 
those individual requirements, except for adding appropriate periodic 
monitoring when necessary, without change. Therefore, title V and the 
individual rule's electronic reporting requirements are the same.
    Commenters also asked for clarification that the transition to the 
new reporting methodology would apply to an entire reporting period 
instead of becoming effective in the middle of a reporting period, 
resulting in two different reports being prepared. The EPA's intent was 
not to require two different reports to be prepared for one reporting 
period. The EPA has clarified in this action that the reporting 
template should be used at the beginning of the first full reporting 
period after the template has been available in CEDRI for 1 year.
    Commenters expressed concern regarding the electronic reporting 
template and asked for more time to meet with the EPA to develop and 
understand the spreadsheet. Commenters also provided feedback on the 
spreadsheet. The EPA agrees that more time is needed to develop the 
template and to work with stakeholders to understand how to use the 
spreadsheet. As such, the EPA is changing the compliance date for using 
the spreadsheet template to be 1 year after the final template is 
available in CEDRI. The EPA will work with stakeholders to develop the 
spreadsheet and to provide training on CEDRI and how to complete the 
spreadsheet. Because the EPA intends to work with stakeholders to 
update the template in the future, it has not placed an updated version 
of the template in the docket for this rulemaking.

the corresponding responses, see the memorandum in the docket, National 
Emission Standards for Hazardous Air Pollutants: Paper and Other Web 
Coating (40 CFR part 63, subpart JJJJ) Residual Risk and Technology 
Review, Final Amendments--Response to Public Comments on September 19, 
2019 Proposal.
4. What is the rationale for our final approach and final decisions for 
the electronic reporting requirement?
    The EPA is finalizing, as proposed, the requirement that owners or 
operators of POWC facilities submit electronic copies of initial 
notifications, notifications of compliance status, performance test 
reports, performance evaluation reports, and semiannual compliance 
reports using CEDRI. The EPA is finalizing that the deadline to use the 
CEDRI semiannual reporting template is 1 year after the template has 
been available in CEDRI. The EPA is finalizing that the electronic 
submittal of the notice of compliance status should be in pdf form 
instead of the semiannual reporting template. The EPA is also 
finalizing, as proposed, provisions that allow facility owners or 
operators a process to request extensions for submitting electronic 
reports for circumstances beyond the control of the facility (i.e., for 
a possible outage in the CDX or CEDRI or for a force majeure event). 
The amendments will increase the usefulness of the data contained in 
those reports; is in keeping with current trends in data availability 
and transparency; will further assist in the protection of public 
health and the environment; will improve compliance by facilitating the 
ability of regulated facilities to demonstrate compliance with 
requirements and by facilitating the ability of delegated state, local, 
tribal, and territorial air agencies and

[[Page 41286]]

the EPA to assess and determine compliance; and will ultimately reduce 
burden on regulated facilities, delegated air agencies, and the EPA.

memorandum, Electronic Reporting Requirements for New Source 
Performance Standards (NSPS) and National Emission Standards for 
Hazardous Air Pollutants (NESHAP) Rules, Docket ID Item No. EPA-HQ-OAR-
2018-0416-0165.

G. Temperature Sensor Validation

1. What did we propose?
    As discussed in the preamble to the proposed rule (84 FR 49382, 
September 19, 2019), at 40 CFR 63.3350(e)(9), the original POWC NESHAP 
required facilities to conduct an electronic calibration of the 
temperature monitoring device every 3 months or, if calibration could 
not be performed, replace the temperature sensor. Facilities subject to 
the standard have explained to the EPA that they are not aware of a 
temperature sensor manufacturer that provides procedures or protocols 
for conducting electronic calibration of temperature sensors. 
Facilities have reported that because they cannot calibrate their 
temperature sensors, the alternative is to replace them every 3 months. 
Industry representatives explained that this is burdensome and 
requested that an alternative approach to the current requirement in 40 
CFR 63.3350(e)(9) be considered.
    The EPA proposed to modify 40 CFR 63.3350(e) to allow multiple 
alternative approaches to temperature sensor validation. The first 
alternative allows the use of a National Institute of Standards and 
Technology (NIST) traceable temperature measurement device or simulator 
to confirm the accuracy of any temperature sensor placed into use for 
at least one quarterly period, where the accuracy of the temperature 
measurement must be within 2.5 percent of the temperature measured by 
the NIST traceable device or 5 degrees Fahrenheit, whichever is 
greater. The second alternative allows the temperature sensor 
manufacturer to certify the electrical properties of the temperature 
sensor. The third alternative codifies the common practice of replacing 
temperature sensors quarterly. The fourth alternative allows for the 
permanent installation of a redundant temperature sensor as close as 
practicable to the process temperature sensor. The redundant sensors 
must read within 25 degrees Fahrenheit of each other for thermal and 
catalytic oxidizers.
2. What changed since proposal?
    Comments were received on the temperature sensor validation 
amendments requesting clarification on the requirements. The EPA has 
clarified the requirements, as discussed below, in the final 
rulemaking.
3. What are the key comments and what are our responses?
    Commenters identified inconsistencies between 40 CFR 63.8 and the 
POWC NESHAP. Specifically, the commenters noted that the proposed 
amendments require ``validation'' whereas 40 CFR 63.8 requires 
``calibration.'' The EPA proposed to remove the term ``calibration'' 
from the POWC NESHAP because temperature sensors such as thermocouples 
do not typically have calibration procedures. To fix this 
inconsistency, the EPA is finalizing changes to Table 2 for the 40 CFR 
63.8(c)(3) entry to direct affected sources to 40 CFR 
63.3350(e)(10)(iv) for temperature sensor validation procedures in lieu 
of calibration requirements. Additionally, the EPA is finalizing 
changes to Table 2 for the 40 CFR 63.8(d)(1)-(2) entry to direct 
affected sources to 40 CFR 63.3350(e)(5) for continuous parameter 
monitoring system (CPMS) quality control procedures and to the 40 CFR 
63.8(d)(3) entry to state that it does not apply, because 40 CFR 
63.3350(e)(5) specifies the program of corrective action. Commenters 
also questioned whether Table 2 requires a notification of performance 
evaluation for temperature sensors under 40 CFR 63.8(e)(2). The EPA is 
also finalizing changes to Table 2 to clarify notifications are not 
required for temperature sensor validations.
    Commenters provided background information on thermocouple accuracy 
and calibrations and requested that the EPA adopt mechanical 
validations as an option to verify temperature sensor operation. These 
mechanical validations include visually inspecting the head and wiring 
of the device and monitoring the function/non-function of the device. 
Commenters explained that this type of validation is appropriate 
because thermocouples typically fail instead of drifting and becoming 
less accurate. In response to this comment, the EPA added mechanical 
validations as an option for verifying temperature sensor operation in 
the final rule.
    Similarly, commenters requested that the requirement in 40 CFR 
63.3350(e)(10)(vi) for quarterly inspection of all components for 
integrity and all electrical connections for continuity, oxidization, 
and galvanic corrosion be removed. Commenters noted that this 
requirement is redundant because electronic monitoring systems are 
designed to alert facility personnel if a signal from the temperature 
sensor is interrupted. The commenters suggested that the EPA simplify 
the requirement to include only a quarterly inspection of thermocouple 
components for proper connection and integrity and clarify that any 
such inspection only applies to the temperature sensor and not the 
entire oxidation system. The EPA did not intend to create redundant 
burden with the proposed requirements. The Agency agrees with the 
commenter and is requiring in the final rule a quarterly inspection of 
the thermocouple components or to continuously operate an electronic 
monitoring system designed to notify personnel if the temperature 
sensor signal is interrupted at 40 CFR 63.3350(e)(10)(vi).
    Commenters supported the proposed options for testing the accuracy 
of temperature sensors and requested clarification on whether the use 
of dual-sensor thermocouples or the use of multiple sensors in the 
oxidizer combustion chamber would meet the proposed requirements. The 
Agency has added a new subsection to clarify that these options would 
meet the finalized requirements. Additionally, the EPA reviewed the 
proposed temperature sensor validation regulatory text and determined 
that, as proposed, it was vague and sometimes inconsistent. For 
example, the proposed amendments said to validate the temperature 
sensor quarterly by following the applicable procedures in the 
manufacturer's owner's manual. The EPA received additional information 
and found that owner's manuals specified annual inspection procedures. 
Also as proposed, facilities would need to quarterly validate by 
permanently installing a redundant temperature sensor, which was vague 
and confusing to affected sources. The EPA has amended 40 CFR 
63.3350(e)(10)(iv) to clarify each option for verifying that a 
temperature sensor is operating properly and how frequently to perform 
the verification. The EPA is finalizing the following verification 
options:
     Semiannually compare the temperature sensor to a NIST 
traceable temperature measurement device;
     annually validate the temperature sensor by following 
applicable mechanical and electrical validation procedures in the 
manufacturer's owner's manual;
     annually request the temperature sensor manufacturer to 
certify or re-certify electromotive force;

[[Page 41287]]

     annually replace the temperature sensor with a new 
certified temperature sensor;
     permanently install a redundant temperature sensor as 
close as practicable to the process temperature sensor; or
     permanently install a temperature sensor with dual sensors 
to account for the possibility of failure.
    One commenter requested that the required accuracy of 2.5 percent 
at 40 CFR part 63.3350(e)(10)(iv)(A) apply equally at 40 CFR part 
63.3350(e)(10)(iv)(E) instead of 25 degrees Fahrenheit. The commenter 
was not aware of any reason to specify different levels of accuracy 
between the proposed validation methods. With this final action, the 
EPA has changed the 25 degrees Fahrenheit requirement in 40 CFR 
63.3350(e)(10)(iv)(E) to be 2.5 percent to be consistent with the 
requirements of 40 CFR 63.3350(e)(10)(iv)(A).
    Commenters also requested that the requirement to calibrate the 
chart recorder or data logger in section 40 CFR 63.3350(e)(10)(i) be 
removed because it is not feasible to calibrate either device, and most 
facilities now use an electronic signal to record temperature data for 
compliance purposes, not a chart recorder. The EPA agrees and has 
removed this statement from the regulatory text.
    For detailed comment summaries regarding the temperature sensor 
validation requirements and corresponding responses, see the memorandum 
in the docket, National Emission Standards for Hazardous Air 
Pollutants: Paper and Other Web Coating (40 CFR part 63, subpart JJJJ) 
Residual Risk and Technology Review, Final Amendments--Response to 
Public Comments on September 19, 2019 Proposal.
4. What is the rationale for our final approach and final decisions for 
the temperature senor calibration requirement?
    The EPA proposed modifications to 40 CFR 63.3350(e) to allow 
multiple alternative approaches to temperature sensor calibration to 
address concerns raised by affected facilities prior to proposal. After 
reviewing the public comments received, the Agency is clarifying the 
requirements in this final rulemaking, as discussed above. These 
amendments ensure that the temperature sensors are operating properly 
to demonstrate continuous compliance with the emission standards.

H. Operating Parameter Clarification

1. What did we propose?
    The EPA proposed to clarify language in 40 CFR 63.3370 which 
previously implied all deviations in operating parameters result in 
non-compliance with the standard. Specifically, the EPA proposed at 40 
CFR 63.3370(k)(5) to clarify that each 3-hour average operating 
parameter that is outside of the operating limit range established 
during a performance test should be assumed to have zero control and 
all HAP must be assumed to be emitted for that period in the monthly 
compliance calculation.
2. What changed since proposal?
    The EPA is finalizing the clarification that a deviation from a 3-
hour average operating parameter is not a deviation of the standard, 
unless the emission limitations for the month in which the deviation 
occurred are exceeded. Based on public comment, the EPA has also added 
the option in 40 CFR 63.3370(k)(5) for a facility to develop a control 
destruction efficiency curve for use in determining compliance instead 
of assuming zero control for all deviations. The EPA has also added 
minor clarifications as discussed below.
3. What are the key comments and what are our responses?
    Commenters supported the EPA's proposed clarification that 
deviations in operating parameters are not automatically indicative of 
non-compliance with the POWC standard. Commenters also stated that a 
deviation from a 3-hour operating limit does not indicate non-
compliance because the standard is based on a monthly average. The EPA 
agrees that the intent of the clarification was for operating 
parameters of add-on control devices only, as the requirement was 
placed in 40 CFR 63.3370(k)(5) which only applies to add-on control 
devices and not coating lines using compliant coatings.
    Several commenters disagreed with the EPA's proposal that each 3-
hour average operating parameter that is outside of the operating limit 
range established during a performance test should be assumed to have 
``zero control.'' Commenters asserted that there was no scientific 
basis for this assumption and indicated that if a performance test 
performed well above the minimum required destruction efficiency, 
dropping below the established temperature may have no effect on the 
destruction efficiency. Commenters recommended that the EPA allow 
facilities to develop a control curve based on test data or engineering 
data that documents the level of control achieved at temperatures lower 
than the performance test established temperature. The EPA has 
considered the commenters' suggestion and have added the option to 
develop a control curve for add-on control devices at 40 CFR 
63.3360(e)(4). Facilities must work with their permitting authority to 
develop the control curve.
    For detailed comment summaries regarding the operating parameter 
clarification and responses, see the memorandum in the docket, National 
Emission Standards for Hazardous Air Pollutants: Paper and Other Web 
Coating (40 CFR part 63, subpart JJJJ) Residual Risk and Technology 
Review, Final Amendments--Response to Public Comments on September 19, 
2019 Proposal.
4. What is the rationale for our final approach and final decisions for 
the operating parameter clarification?
    Operating parameters were established in the original POWC NESHAP 
to aid in determining compliance, but operating parameters were not 
intended to constitute a violation of the emission standard. For 
example, one 3-hour average regenerative thermal oxidizer firebox 
temperature below the setpoint established during the stack test would 
not necessarily indicate a violation of the POWC emission standard for 
the month, but it is a deviation of the operating parameter limit. The 
EPA is finalizing, as proposed, language to clarify this distinction 
with minor changes based on public comment.

I. IBR Under 1 CFR Part 51 for the POWC NESHAP

1. What did we propose?
    In accordance with requirements of 1 CFR 51.5, the EPA proposed to 
incorporate by reference the following voluntary consensus standards 
(VCS) into 40 CFR 63.14:
     ASTM D2369-10 (Reapproved 2015)\e\, Standard Test Method 
for Volatile Content of Coatings, IBR approved for 40 CFR 63.3360(c).
     ASTM D2697-03 (Reapproved 2014), Standard Test Method for 
Volume Nonvolatile Matter in Clear or Pigmented Coatings, IBR approved 
for 40 CFR 63.3360(c).
     ASTM 3960-98, Standard Practice for Determining Volatile 
Organic Compound (VOC) Content of Paints and Related Coatings, IBR 
approved for 40 CFR 63.3360(d).
     ASTM D6093-97, (Reapproved 2016), Standard Test Method for 
Percent

[[Page 41288]]

Volume Nonvolatile Matter in Clear or Pigmented Coatings Using a Helium 
Gas Pycnometer, IBR approved for 40 CFR 63.3360(c).
     ASTM D2111-10 (Reapproved 2015), Standard Test Methods for 
Specific Gravity of Halogenated Organic Solvents and Their Admixtures, 
IBR approved for 40 CFR 63.3360(c).
     ASTM D1963-85 (Reapproved 1996), Standard Test Method for 
Specific Gravity of Drying Oils, Varnishes, Resins, and Related 
Materials at 25/25[deg]C (Withdrawn 2004), IBR approved for 40 CFR 
63.3360(c).
2. What changed since proposal?
    No changes to the proposed IBR were made since publication of the 
proposal (84 FR 49405, September 19, 2019).
3. What are the key comments and what are our responses?
    No comments were received on the proposed IBR of the standards into 
40 CFR 63.14.
4. What is the rationale for our final approach and final decisions for 
the IBR under 1 CFR part 51?
    In accordance with requirements of 1 CFR 51.5, the EPA is 
finalizing, as proposed, the IBR of the documents listed in section 
IV.I.1 of this preamble.

J. Technical and Editorial Changes

1. Removal of OSHA-Defined Carcinogens Reference
a. What did we propose?
    The EPA proposed to amend sections 40 CFR 63.3360(c)(1)(i) and (3), 
which describe how to demonstrate initial compliance with the emission 
limitations using the compliant material option, to remove references 
to OSHA-defined carcinogens as specified in 29 CFR 1910.1200(d)(4). The 
reference to OSHA-defined carcinogens as specified in 29 CFR 
1910.1200(d)(4) is intended to specify which compounds must be included 
in calculating total organic HAP content of a coating material if they 
are present at 0.1 percent or greater by mass. The Agency proposed to 
remove this reference because 29 CFR 1910.1200(d)(4) has been amended 
and no longer readily defines which compounds are carcinogens. The EPA 
proposed to replace the references to OSHA-defined carcinogens and 29 
CFR 1910.1200(d)(4) with a list (in proposed new Table 3 to Subpart 
JJJJ of Part 63--List of Hazardous Air Pollutants That Must Be Counted 
Relative to Determining Coating HAP Content if Present at 0.1 Percent 
or More By Mass) of those organic HAP that must be included in 
calculating total organic HAP content of a coating material if they are 
present at 0.1 percent or greater by mass.
b. What changed since proposal?
    The EPA has changed the approach for the removal of the reference 
to 29 CFR 1910.1200(d)(4) based on public comment. The EPA is not 
finalizing the proposed Table 3 to 40 CFR part 63, subpart JJJJ, and is 
finalizing a reference to appendix A to 29 CFR 1910.1200 where 29 CFR 
1910.1200(d)(4) was previously referenced.
c. What are the key comments and what are our responses?
    Multiple commenters asked that the EPA delete the proposed Table 3 
to 40 CFR part 63, subpart JJJJ, and modify the proposed methodology 
for determining the HAP content of coatings. Commenters pointed out 
that 29 CFR 1910.1200(d)(4) was not a list, but a list of references 
for manufacturers and importers to use to classify chemicals. 
Commenters asked that the POWC NESHAP reference the current OSHA Safety 
Data Sheets (SDS) rule (29 CFR 1910.1200) instead of adding a static 
list in the form of the proposed Table 3 to 40 CFR part 63, subpart 
JJJJ. The EPA agrees the commenters' suggestion is a more-streamlined 
solution for updating the OSHA reference and is not finalizing the 
table in the final rule and has added the reference to appendix A to 29 
CFR 1910.1200.
    For detailed comment summaries regarding the OSHA-defined 
carcinogens reference and the corresponding responses, see the 
memorandum in the docket, National Emission Standards for Hazardous Air 
Pollutants: Paper and Other Web Coating (40 CFR Part 63, Subpart JJJJ) 
Residual Risk and Technology Review, Final Amendments--Response to 
Public Comments on September 19, 2019 Proposal.
d. What is the rationale for our final approach?
    The EPA has reviewed the comments received regarding the removal of 
the OSHA-defined carcinogens language and agrees that appendix A to 29 
CFR 1910.1200 is an appropriate replacement for the outdated 29 CFR 
1910.1200(d)(4) reference. Given that the OSHA language that the POWC 
proposal sought to replace is in appendix A, for the final POWC 
amendment the EPA is finalizing the regulatory text at 40 CFR 
63.3360(c)(1)(i) to be as follows:
    (i) Include each organic HAP determined to be present at greater 
than or equal to 0.1 mass percent for Occupational Safety and Health 
Administration (OSHA)-defined carcinogens as specified in section A.6.4 
of appendix A to 29 CFR 1910.1200 and greater than or equal to 1.0 mass 
percent for other organic HAP compounds.
2. Clarification of Compliance Demonstration Options
a. What did we propose?
    The EPA proposed an introductory paragraph and a new subsection to 
clarify the compliance demonstration requirements in 40 CFR 63.3370. As 
originally promulgated, it was not clear that compliance can be 
demonstrated based on individual web coating lines, groups of web 
coating lines, or all of the web coating lines located at an affected 
facility. An introductory paragraph to 40 CFR 63.3370 was proposed to 
clarify the intent that compliance can be demonstrated across the web 
coating lines in a facility by grouping them or treating them 
individually or a combination of both. Additionally, a new subsection 
40 CFR 63.3370(r) was proposed to clarify that compliance with the 
subpart can be demonstrated using a mass-balance approach. While the 
compliance calculations included in 40 CFR 63.3370(b)-(p) are thorough, 
there are instances where variables in the equations are not needed, 
resulting in confusion by the regulated facilities and the regulating 
agencies as to what is required to demonstrate compliance. The mass-
balance approach proposed in 40 CFR 63.3370(r) clarifies the original 
intent of the rule.
b. What changed since proposal?
    The EPA received comments suggesting minor edits to the proposed 
language regarding the mass-balance compliance demonstration approach 
and has incorporated these edits, as appropriate, as discussed below. 
No changes were made to the introductory paragraph to 40 CFR 63.3370 
and the EPA is finalizing this section, as proposed, in this action.
c. What are the key comments and what are our responses?
    Commenters expressed support for the proposed clarification that 
compliance can be demonstrated across multiple lines. Commenters also 
felt that this clarification reduces the potential for inconsistent 
regulatory interpretations by sources and permitting agencies and makes 
the POWC NESHAP consistent with other coating rules. The EPA 
acknowledges the commenters' support and is finalizing the 
clarification, as proposed.

[[Page 41289]]

    Commenters noted that the EPA incorrectly stated procedures for 
demonstrating compliance by mass-balance at 40 CFR 63.3370(r)(1)--the 
mass of HAP emitted during the month should be divided by the mass 
applied according to any of the procedures listed in 40 CFR 
63.3320(b)(1)-(3). Commenters also suggested additional regulatory text 
revisions to be consistent with proposed edits to other sections. The 
EPA has reviewed these comments and agrees with the commenters 
suggested edits to correct the mass-balance calculation and has done so 
in this rulemaking.
    For detailed comment summaries regarding the clarification of the 
compliance demonstration options and the corresponding responses, see 
the memorandum in the docket, National Emission Standards for Hazardous 
Air Pollutants: Paper and Other Web Coating (40 CFR Part 63, Subpart 
JJJJ) Residual Risk and Technology Review, Final Amendments--Response 
to Public Comments on September 19, 2019 Proposal.
d. What is the rationale for our final approach?
    The EPA proposed, and is finalizing, amendments to the regulatory 
text to clarify that compliance can be demonstrated based on individual 
web coating lines, groups of web coating lines, or all of the web 
coating lines located at an affected facility. The EPA is finalizing 
corrections to the mass balance calculation. Additionally, the EPA 
proposed, and is finalizing, a new subsection in 40 CFR 63.3370(r) to 
clarify the intent of the rule as a mass-balance approach of 
demonstrating compliance. The clarification to the compliance 
demonstration options were made to help reduce confusion among 
regulated entities and regulating authorities.
3. Clarification of Coating Materials Definition
a. What did we propose?
    The EPA proposed to revise the coating material definition in 40 
CFR 63.3310 to clarify that coating materials are liquid or semi-liquid 
materials. Additionally, the EPA proposed to revise the web coating 
line definition to clarify that coating materials are liquid or semi-
liquid.
b. What changed since proposal?
    The EPA has clarified in the definition of coating materials to 
include hot melt adhesives and other hot melt materials.
c. What are the key comments and what are our responses?
    Commenters supported the EPA's proposed clarifications to the 
definition of coating materials and further suggested that the EPA 
revise the definition to ensure that it is not incorrectly interpreted 
to exclude hot melt adhesives or coatings. The EPA agrees with the 
commenters and hot melt materials are included in the revised 
regulatory text in 40 CFR 63.3310 to reflect this.
    For detailed comment summaries regarding the coating materials 
definition and the corresponding responses, see the memorandum in the 
docket, National Emission Standards for Hazardous Air Pollutants: Paper 
and Other Web Coating (40 CFR Part 63, Subpart JJJJ) Residual Risk and 
Technology Review, Final Amendments--Response to Public Comments on 
September 19, 2019 Proposal.
d. What is the rationale for our final approach?
    The EPA is finalizing, as proposed, revisions to the coating 
material definition in 40 CFR 63.3310 to clarify that coating materials 
are liquid or semi-liquid materials and revisions to the web coating 
line definition to clarify that coating materials are liquid or semi-
liquid. The EPA is also finalizing the clarification that hot melt 
materials are included in the definition and that vapor deposition and 
dry abrasive materials deposited onto a coated surface area are 
excluded from the definition. These revisions will improve regulatory 
clarity by confirming that the weight of solid materials should not be 
accounted for in the compliance demonstration calculations, and that 
vapor-deposition coating is not covered by this subpart.
4. Addition of Web Coating Line Usage Threshold
a. What did we propose?
    The EPA proposed to add a usage threshold to 40 CFR 63.3300(h), 
similar to that in 40 CFR part 63, subpart OOOO, that requires a web 
coating line that coats both paper and another substrate, such as 
fabric, to comply with the subpart that corresponds to the predominate 
activity conducted. The EPA proposed to define predominant activity to 
be 90 percent of the mass of substrate coated during the compliance 
period. For example, a web coating line that coats 90 percent or more 
of a paper substrate, and 10 percent or less of a fabric substrate, 
would be subject to this subpart and not 40 CFR part 63, subpart OOOO.
b. What changed since proposal?
    Since proposal, the EPA has clarified that the predominant activity 
should be determined on a calendar year basis.
c. What are the key comments and what are our responses?
    Commenters supported usage thresholds for converting lines that 
coat both paper and another substrate. Commenters noted that the usage 
of the term ``affected source'' in the proposal appears to be 
inconsistent with the example because the POWC NESHAP is the collection 
of all web coating lines. Additionally, commenters thought the term 
compliance period could be interpreted to require a facility performing 
different types of coating to determine which NESHAP applies on a 
monthly basis. Commenters requested that the EPA clarify these issues. 
The EPA agrees with the commenters and have edited the regulatory text 
to clarify that predominant activity must be determined on a calendar 
year basis.
    For detailed comment summaries regarding the web coating line 
threshold and the corresponding responses, see the memorandum in the 
docket, National Emission Standards for Hazardous Air Pollutants: Paper 
and Other Web Coating (40 CFR Part 63, Subpart JJJJ) Residual Risk and 
Technology Review, Final Amendments--Response to Public Comments on 
September 19, 2019 Proposal.
d. What is the rationale for our final approach?
    The EPA reviewed the public comments and added clarifying language 
to the proposed usage threshold. This language was added to promote 
regulatory certainty and reduce burden from sources that could be 
subject to multiple NESHAP.
5. Addition of Printing Activity Exemption
a. What did we propose?
    The EPA proposed to add a printing activity exemption to 40 CFR 
63.3300(i) which allows for modified web coating lines already subject 
to this subpart to continue to demonstrate compliance with this 
subpart, in lieu of demonstrating compliance with 40 CFR part 63, 
subpart KK (Printing and Publishing NESHAP).
b. What changed since proposal?
    The EPA has clarified the language in the printing activity 
exemption to allow for existing and modified lines to be

[[Page 41290]]

subject to the POWC NESHAP in lieu of 40 CFR part 63, subpart KK.
c. What are the key comments and what are our responses?
    Multiple commenters supported the EPA's proposed printing activity 
exemption to allow for modified POWC lines already subject to the POWC 
NESHAP to continue to demonstrate compliance with 40 CFR part 63, 
subpart JJJJ in lieu of demonstrating compliance with 40 CFR part 63, 
subpart KK. Commenters suggested that this exemption also apply to 
existing sources as well as modified sources (e.g., for POWC web 
coating lines that already have a product and packaging rotogravure 
print station and/or a wide-web flexographic print station). The 
commenter noted that, as written, if during a single month the line 
exceeds 5 percent of the total mass of materials applied at the print 
station, the line applicability would permanently change to the 
Printing and Publishing NESHAP. The EPA agrees with the commenters and 
has clarified the regulatory text in this action, as appropriate.
    For detailed comment summaries regarding the printing activity 
exemption and the corresponding responses, see the memorandum in the 
docket, National Emission Standards for Hazardous Air Pollutants: Paper 
and Other Web Coating (40 CFR Part 63, Subpart JJJJ) Residual Risk and 
Technology Review, Final Amendments--Response to Public Comments on 
September 19, 2019 Proposal.
d. What is the rationale for our final approach?
    In this rulemaking, the EPA is finalizing a printing activity 
exemption to 40 CFR 63.3300(i) which allows for modified and existing 
web coating lines already subject to this subpart to continue to 
demonstrate compliance with this subpart, in lieu of demonstrating 
compliance with 40 CFR part 63, subpart KK (i.e., the Printing and 
Publishing NESHAP). This exemption will reduce regulatory burden 
without resulting in increased emissions.
6. Clarification of Testing Requirements
a. What did we propose?
    The EPA proposed to remove the ``by compound'' statement in 40 CFR 
63.3320(b)(4) to clarify that the standard is 20 parts per million by 
volume (ppmv) for the total of organic HAP emitted, not 20 ppmv for 
each individual HAP emitted. This is consistent with the test methods 
used in this subpart, which test for total HAP concentration.
b. What changed since proposal?
    The EPA is finalizing the removal of ``by compound'' in 40 CFR 
63.3220(b)(4) to clarify that the 20 ppmv standard applies to the total 
of organic HAP emitted, not to each individual HAP. As part of our 
review, the EPA found four additional instances of ``by compound'' in 
40 CFR 63.3370(a)(5), (f), (f)(3), and (f)(3)(iii) that also needed to 
be removed.
c. What are the key comments and what are our responses?
    Commenters supported the EPA's proposal to remove ``by compound'' 
in 40 CFR 63.3220(b)(4) to clarify that the 20 ppmv standard applies to 
the total of organic HAP emitted, not to each individual HAP.
d. What is the rationale for our final approach?
    The removal of ``by compound'' makes the POWC NESHAP consistent 
with the test methods referenced in the subpart, as they test for total 
HAP concentration, not individual HAP compounds.
7. Applicability to Sources Using Only Non-HAP Coatings
a. What did we propose?
    The EPA requested comment on changing the applicability of the POWC 
NESHAP to exclude sources that only use non-HAP coatings but are 
located at a major source to reduce regulatory burden. As identified 
during the development of the risk modeling input file and discussed in 
section III.C of the preamble to the proposed rule (84 FR 49406, 
September 19, 2019), some facilities that utilize only non-HAP coatings 
are subject to the POWC NESHAP because they perform web coating 
operations and are a major source because of non-POWC source category 
emissions. For example, a non-HAP coating line used to produce paper 
towel cores may be located at an integrated pulp and paper facility 
that is a major source because of emissions from the pulping 
operations. This facility would be required to comply with the 
requirements of 40 CFR part 63, subpart JJJJ, even though the coatings 
used contain no HAP, and, therefore, no HAP are emitted from the web 
coating lines.
b. What changed since proposal?
    The EPA received supportive comments regarding the change of 
applicability to sources using only non-HAP coatings. The Agency has 
reviewed the public comments and, instead of changing the applicability 
of the subpart, is finalizing an exemption for reporting requirements 
for these sources.
c. What are the key comments and what are our responses?
    Commenters supported the EPA's proposal to reduce regulatory burden 
by excluding sources that are located at a major source of HAP but do 
not use coatings that contain HAP for the POWC emission sources. 
Commenters stated that the change will reduce regulatory burden without 
increasing emissions and could incentivize sources to convert to non-
HAP coatings to avoid applicability of the POWC NESHAP, resulting in 
emissions reductions. Commenters further suggested that the exclusion 
is a logical step under the EPA's efforts to reduce regulatory burden 
and is similar in key aspects to the rulemaking to rescind the EPA's 
``once in, always in'' policy. Commenters suggested that the EPA 
clarify that all of the subject coating lines at the facility must use 
non-HAP coatings to qualify for the exclusion. The EPA has reviewed 
these comments and has added regulatory text exempting sources that 
only use non-HAP coatings on all of the subject web coating lines at 
the facility from on-going compliance reporting requirements.
    For detailed comment summaries regarding applicability to sources 
only using non-HAP coatings and the corresponding responses, see the 
memorandum in the docket, National Emission Standards for Hazardous Air 
Pollutants: Paper and Other Web Coating (40 CFR Part 63, Subpart JJJJ) 
Residual Risk and Technology Review, Final Amendments--Response to 
Public Comments on September 19, 2019 Proposal.
d. What is the rationale for our final approach?
    The EPA requested comment on changing the applicability of sources 
using only non-HAP coatings and received comments supporting the 
change. The EPA is finalizing an exemption to on-going reporting 
requirements for these sources as it will reduce regulatory burden 
without increasing emissions.
8. Oxidizer Temperature Monitoring
a. What did we propose?
    The EPA proposed to add language to recognize that thermal 
oxidizers can demonstrate compliance with the standard as long as the 
3-hour average firebox temperature does not drop lower

[[Page 41291]]

than 50 degrees Fahrenheit below the average combustion temperature 
established during the performance test to promote consistency between 
the Pressure Sensitive Tape and Label Surface Coating Operations NSPS 
(40 CFR part 60, subpart RR) and the POWC NESHAP, as well as to account 
for temperature swings due to startup and/or shutdown of web coating 
lines.
b. What changed since proposal?
    The EPA has made minor clarifications to the regulatory text to 
promote consistency throughout the subpart and has added similar 
language for catalytic oxidizers.
c. What are the key comments and what are our responses?
    Commenters were supportive of the EPA's proposed language for 
thermal oxidizers and requested that it be included for catalytic 
oxidizers as well. Additionally, commenters noted that the Pressure 
Sensitive Tape and Label Surface Coating Operations NSPS allows for 
setting the minimum temperature drop across the catalyst bed at 80 
percent of the average temperature difference during the most recent 
performance test and requested that this language be added to promote 
consistency between the two rules. The Agency has reviewed the 
commenters suggestions and agree that it is appropriate to add the 
temperature language for catalytic oxidizers. To ensure complete 
combustion, the EPA also added a requirement that the catalyst's 
minimum temperature must always be 50 degrees Fahrenheit above the 
catalyst's ignition temperature.
    Commenters also suggested edits to promote consistency throughout 
the subpart as it relates to the temperature language. The EPA has 
reviewed these suggestions and made edits to the regulatory text in 
this action, as appropriate.
    For detailed comment summaries regarding the oxidizer temperature 
monitoring requirements and the corresponding responses, see the 
memorandum in the docket, National Emission Standards for Hazardous Air 
Pollutants: Paper and Other Web Coating (40 CFR Part 63, Subpart JJJJ) 
Residual Risk and Technology Review, Final Amendments--Response to 
Public Comments on September 19, 2019 Proposal.
d. What is the rationale for our final approach?
    The EPA proposed to add language to recognize that thermal 
oxidizers can demonstrate compliance with the standard as long as the 
3-hour average firebox temperature does not drop lower than 50 degrees 
Fahrenheit below the average combustion temperature established during 
the performance test to promote consistency between the Pressure 
Sensitive Tape and Label Surface Coating Operations NSPS and the POWC 
NESHAP, as well as to account for temperature swings due to startup 
and/or shutdown of web coating lines. After reviewing the public 
comments, the EPA has added the same requirements to catalytic 
oxidizers. In addition, the EPA has added language similar to that in 
the Pressure Sensitive Tape and Label Surface Coating Operations NSPS 
to allow for setting the minimum temperature drop across the catalyst 
bed at 80 percent of the average temperature difference during the most 
recent performance test. To ensure complete combustion, the EPA also 
added a requirement that the catalyst's minimum temperature must always 
be 50 degrees Fahrenheit above the catalyst's ignition temperature.
9. Compliance Report Content
a. What did we propose?
    The EPA proposed new reporting requirements at 40 CFR 63.3400(c)(2) 
that would require facilities to record data for failures to meet an 
applicable standard, estimate the quantity of each regulated pollutant 
over any emission limit and a description of the method used, and 
document any actions taken to minimize emissions.
b. What changed since proposal?
    The EPA has revised the compliance report content requirements in 
40 CFR 63.3400(c)(2) to clarify what should be reported.
c. What are the key comments and what are our responses?
    Commenters noted that the new reporting requirements should be 
eliminated because they go beyond the General Provisions at 40 CFR 
63.10 and, because compliance is determined monthly, short deviations 
are not likely to cause excess emissions. Commenters further noted that 
the proposed additions are not relevant to a rule where compliance is 
not demonstrated on a short-term basis. The EPA has reviewed the 
commenters concerns and agree that the language is not appropriate for 
40 CFR part 63, subpart JJJJ. The EPA has revised the requirements in 
40 CFR 63.3400(c)(2) to clarify what is required to be reported and has 
also revised the requirements in 40 CFR 63.3410(c) to clarify what 
records should be maintained.
    Additionally, while the EPA was reviewing the report content 
requirements, it became clear that the requirements were confusing as 
to what should be reported for facilities using compliant coatings 
versus facilities using add-on controls. The EPA has clarified that 40 
CFR 63.3400(c)(2)(v) applies to facilities using only compliant 
coatings (i.e., those that do not use a CMS). The EPA also clarified 
that 40 CFR 63.3400(c)(2)(vi) applies to facilities that have add-on 
control devices (i.e., those that use a CPMS or a continuous emission 
monitoring system). These amendments should improve regulatory clarity.
    For detailed comment summaries regarding compliance report content 
and the corresponding responses, see the memorandum in the docket, 
National Emission Standards for Hazardous Air Pollutants: Paper and 
Other Web Coating (40 CFR Part 63, Subpart JJJJ) Residual Risk and 
Technology Review, Final Amendments--Response to Public Comments on 
September 19, 2019 Proposal.
d. What is the rationale for our final approach?
    The EPA proposed new reporting requirements at 40 CFR 63.3400(c)(2) 
that would require facilities to record data for failures to meet an 
applicable standard, estimate the quantity of each regulated pollutant 
over any emission limit and a description of the method used, and 
document any actions taken to minimize emissions to be consistent with 
recent RTR rulemakings. After reviewing the comments received during 
the public comment period, as well as the regulatory language, it was 
determined that these requirements were not appropriate for 40 CFR part 
63, subpart JJJJ because compliance is demonstrated on a monthly basis 
and therefore these requirements are not being finalized. In response 
to comments, amendments were added to the compliance report contents 
section to clarify what should be reported and by whom.
10. Other Amendments
    The following additional changes were proposed that address 
technical and editorial corrections:
     Revised the references to the other NESHAP in 40 CFR 
63.3300 to clarify the appropriate subparts;
     revised 40 CFR 3350(c) to clarify that bypass valves on 
always-controlled work stations should be monitored;
     revised 40 CFR 63.3350(e)(4) to clarify 3-hour averages 
should be block averages, consistent with the requirements in Table 1 
to Subpart JJJJ of Part 63;

[[Page 41292]]

     revised the monitoring requirements section in 40 CFR 
63.3360 to clarify what constitutes representative conditions;
     revised the recordkeeping requirements section in 40 CFR 
63.3410 to include the requirement to show continuous compliance after 
effective date of regulation;
     revised the terminology in the delegation of authority 
section in 40 CFR 63.3420 to match the definitions in 40 CFR 63.90;
     revised the General Provisions applicability table (Table 
2 to Subpart JJJJ of Part 63) to provide more detail and to make it 
align with those sections of the General Provisions that have been 
amended or reserved over time; and
     renumbered the equations throughout the subpart for 
regulatory clarity.
    No comments were received on these other amendments and, therefore, 
the EPA is finalizing them as proposed.

V. Summary of Cost, Environmental, and Economic Impacts and Additional 
Analyses Conducted

A. What are the affected facilities?

    The POWC source category includes any facility that is located at a 
major source and is engaged in the coating of paper, plastic film, 
metallic foil, and other web surfaces. All the coating lines at a 
subject facility are defined as one affected source. Any new source 
means any affected source for which construction or reconstruction was 
commenced after the date the EPA first proposed regulations 
establishing a NESHAP applicable to the source (i.e., for the POWC 
source category, September 13, 2000). An existing source means any 
source other than a new source. Generally, an additional line at an 
existing facility is considered part of the existing affected source. 
New affected sources are new lines installed at new facilities or at a 
facility with no prior POWC operations.
    There are currently 168 facilities in the United States that are 
subject to the POWC NESHAP. The EPA is aware of one new affected source 
that is under construction that will be subject to the POWC NESHAP in 
the future. The EPA is not aware of any other facilities that are under 
construction or are planned to be constructed which would be considered 
``new facilities'' under the POWC NESHAP.

B. What are the air quality impacts?

    At the current level of control, estimated emissions of total HAP 
are approximately 3,870 tpy. Compared to pre-MACT levels, this 
represents a significant reduction of HAP for the category. When the 
POWC NESHAP was finalized in 2002, the EPA estimated the annual 
baseline HAP emissions from the source category to be approximately 
42,000 tpy (67 FR 72331, December 4, 2002).
    The amendments will require all 168 major sources with equipment 
subject to the POWC NESHAP to operate without the SSM exemption. 
Eliminating the SSM exemption will reduce emissions by requiring 
facilities to meet the applicable standard during SSM periods; however, 
the EPA is unable to quantify the specific emission reductions 
associated with eliminating the exemption. The requirement for repeat 
performance testing once every 5 years for thermal oxidizers and the 
alternative of annual catalyst activity testing for catalytic oxidizers 
will ensure that the control device is operating correctly and may 
reduce emissions, but no method for accurately estimating such 
emissions reduction is available.
    Indirect or secondary air emissions impacts are impacts that would 
result from the increased electricity usage associated with the 
operation of control devices (i.e., increased secondary emissions of 
criteria pollutants from power plants). Energy impacts consist of the 
electricity and steam needed to operate control devices and other 
equipment that would be required under this final rule. The EPA expects 
no secondary air emissions impacts or energy impacts from this 
rulemaking.
    For further information, see the memorandum titled Revised Cost, 
Environmental, and Energy Impacts of Regulatory Options for the Paper 
and Other Web Coatings Risk and Technology Review, in the docket for 
this action (Docket ID No. EPA-HQ-OAR-2018-0416).

C. What are the cost impacts?

    Startup and shutdown are considered normal operations for most 
facilities subject to the POWC NESHAP. The EPA does not believe 
removing the SSM exemption will result in additional incurred costs.
    As discussed in detail in the memorandum titled Revised Cost, 
Environmental, and Energy Impacts of Regulatory Options for the Paper 
and Other Web Coatings Risk and Technology Review, it is estimated that 
65 oxidizers will have to perform repeat performance testing. Fifty 
eight of these 65 are thermal oxidizers, and 3 are catalytic oxidizers. 
For costing purposes, it was assumed that repeat emissions performance 
testing will be performed every 5 years on the thermal oxidizers, and 
annual catalyst activity testing will be conducted on the catalytic 
oxidizers. The estimated cost for an inlet-outlet EPA Method 25A 
performance test (with electronic reporting of results) is $28,000 per 
test and the estimated cost for annual catalyst activity testing is 
$1,000, for an estimated nationwide cost of $1,750,000 (2018$) every 5 
years. The electronic reporting requirement is not expected to require 
any additional labor hours to prepare, compared to the paper semi-
annual compliance reports that are already prepared. Therefore, the 
costs associated with the electronic reporting requirement are zero.

D. What are the economic impacts?

    The economic impact analysis is designed to inform decision makers 
about the potential economic consequences of a regulatory action. To 
assess the potential impact, the largest cost expected to be 
experienced in any one year is compared to the total sales for the 
ultimate owner of the affected facilities to estimate the total burden 
for each facility.
    For the final revisions to the POWC NESHAP, the 168 affected 
facilities are owned by 91 different parent companies, and the total 
costs associated with the final requirements range from less than 
0.000001 to 3 percent of annual sales revenue per ultimate owner. These 
costs are not expected to result in a significant market impact, 
regardless of whether they are passed on to the purchaser or absorbed 
by the firms.
    The EPA also prepared a small business screening assessment to 
determine whether any of the identified affected entities are small 
entities, as defined by the U.S. Small Business Administration. Twenty-
nine of the facilities potentially affected by the final revisions to 
the POWC NESHAP are small entities. However, the costs associated with 
the final requirements for the affected small entities range from 
0.0003 to 3 percent of annual sales revenues per ultimate owner; there 
is one facility with costs of 1.4 percent and one facility with costs 
of 3 percent of annual sales revenues per ultimate owner. Therefore, 
there are no significant economic impacts on a substantial number of 
small entities from these final amendments.

E. What are the benefits?

    Because these final amendments are not considered economically 
significant, as defined by Executive Order 12866, and because we did 
not estimate emission reductions associated with the

[[Page 41293]]

final revisions, the EPA did not estimate any benefits from reducing 
emissions.

F. What analysis of environmental justice did we conduct?

    Executive Order 12898 (59 FR 7629, February 16, 1994) establishes 
federal executive policy on environmental justice. Its main provision 
directs federal agencies, to the greatest extent practicable and 
permitted by law, to make environmental justice part of their mission 
by identifying and addressing, as appropriate, disproportionately high 
and adverse human health or environmental effects of their programs, 
policies, and activities on minority populations and low-income 
populations in the United States.
    To examine the potential for any environmental justice issues that 
might be associated with the source category, the EPA performed a 
demographic analysis, which is an assessment of risk to individual 
demographic groups of the populations living within 5 kilometers (km) 
and within 50 km of the facilities. In the analysis, the EPA evaluated 
the distribution of HAP-related cancer and noncancer risk from the POWC 
source category across different social, demographic, and economic 
groups within the populations living near facilities identified as 
having the highest risks.\6\ The methodology and the results of the 
demographic analysis are presented in a technical report, Risk and 
Technology Review--Analysis of Demographic Factors for Populations 
Living Near Paper and Other Web Coating Facilities, available in the 
docket for this action (Docket ID Item No. EPA-HQ-OAR-2018-0416-0088). 
These results, for various demographic groups, are based on the 
estimated risk from actual emissions levels for the population living 
within 50 km of the facilities.
---------------------------------------------------------------------------

    \6\ Demographic groups included in the analysis are: White, 
African American, Native American, other races and multiracial, 
Hispanic or Latino, children 17 years of age and under, adults 18 to 
64 years of age, adults 65 years of age and over, adults without a 
high school diploma, people living below the poverty level, people 
living 2 times the poverty level, and linguistically isolated 
people.
---------------------------------------------------------------------------

    The results of the POWC source category demographic analysis 
indicate that emissions from the source category expose approximately 
4,300 people to a cancer risk at or above 1-in-1 million and no one is 
exposed to a chronic noncancer TOSHI greater than 1. The specific 
demographic results indicate that the percentage of the population 
potentially impacted by emissions is greater than its corresponding 
national percentage for the white population (86 percent for the source 
category compared to 62 percent nationwide) and for the below-poverty-
level population (17 percent compared to 14 percent nationwide).
    The risks due to HAP emissions from this source category are low 
for all populations. Furthermore, the EPA does not expect this final 
rule to achieve significant reductions in HAP emissions. Therefore, the 
EPA concludes that this final rule will not have disproportionately 
high and adverse human health or environmental effects on minority or 
low-income populations because it does not affect the level of 
protection provided to human health or the environment. However, this 
final rule will provide additional benefits to these demographic groups 
by improving the monitoring, compliance, and implementation of the 
NESHAP.

G. What analysis of children's environmental health did we conduct?

    The EPA does not believe the environmental health or safety risks 
addressed by this action present a disproportionate risk to children. 
The results of the POWC source category demographic analysis indicate 
that emissions from the source category expose approximately 4,300 
people to a cancer risk at or above 1-in-1 million and no one is 
exposed to a chronic noncancer TOSHI greater than 1. The distribution 
of the population with risks above 1-in-1 million is 20 percent for 
ages 0 to 17, 62 percent for ages 18 to 64, and 17 percent for ages 65 
and up. Children ages 0 to 17 constitute 23 percent of the population 
nationwide. Therefore, the analysis shows that actual emissions from 40 
CFR part 63, subpart JJJJ facilities have a slightly smaller impact on 
children ages 0 to 17. This action's health and risk assessments are 
contained in sections III and IV of the preamble to the proposed rule 
and further documented in the risk report titled Residual Risk 
Assessment for the Paper and Other Web Source Category in Support of 
the 2020 Risk and Technology Review Final Rule, which can be found in 
the docket for this action (Docket ID No. EPA-HQ-OAR-2018-0416).

VI. Statutory and Executive Order Reviews

    Additional information about these statutes and Executive Orders 
can be found at https://www.epa.gov/laws-regulations/laws-and-executive-orders.

A. Executive Order 12866: Regulatory Planning and Review and Executive 
Order 13563: Improving Regulation and Regulatory Review

    This action is not a significant regulatory action and was, 
therefore, not submitted to the Office of Management and Budget (OMB) 
for review.

B. Executive Order 13771: Reducing Regulations and Controlling 
Regulatory Costs

    This action is not an Executive Order 13771 regulatory action 
because this action is not significant under Executive Order 12866.

C. Paperwork Reduction Act (PRA)

    The information collection activities in this proposed rule have 
been submitted for approval to OMB under the PRA. The Information 
Collection Request (ICR) document that the EPA prepared has been 
assigned EPA ICR number 1951.09, OMB Control No. 2060-0511. You can 
find a copy of the ICR in the docket for this rule, and it is briefly 
summarized here. The information collection requirements are not 
enforceable until OMB approves them.
    The POWC NESHAP applies to existing facilities and new POWC 
facilities. In general, all NESHAP standards require initial 
notifications, notifications of compliance status, performance tests, 
performance evaluation reports, and periodic reports by the owners/
operators of the affected facilities. They are also required to 
maintain records of the occurrence and duration of any malfunction in 
the operation of an affected facility, or any period during which the 
monitoring system is inoperative. These notifications, reports, and 
records are essential in determining compliance, and are required of 
all affected facilities subject to NESHAP. This information is being 
collected to assure compliance with 40 CFR part 63, subpart JJJJ.
    Respondents/affected entities: POWC facilities.
    Respondent's obligation to respond: Mandatory (40 CFR Part 63, 
Subpart JJJJ).
    Estimated number of respondents: 170.
    Frequency of response: Initially, occasionally, and semiannually.
    Total estimated burden: 17,300 hours (per year). Burden is defined 
at 5 CFR 1320.3(b).
    Total estimated cost: $2,735,000 (per year), includes $765,000 
annualized capital and operation and maintenance costs.
    An agency may not conduct or sponsor, and a person is not required 
to

[[Page 41294]]

respond to, a collection of information unless it displays a currently 
valid OMB control number. The OMB control numbers for the EPA's 
regulations in 40 CFR are listed in 40 CFR part 9. When OMB approves 
this ICR, the Agency will announce that approval in the Federal 
Register and publish a technical amendment to 40 CFR part 9 to display 
the OMB control number for the approved information collection 
activities contained in this final rule.

D. Regulatory Flexibility Act (RFA)

    I certify that this action will not have a significant economic 
impact on a substantial number of small entities under the RFA. The 
small entities subject to the requirements of this action and the 
annualized costs associated with the final requirements in this action 
for the affected small entities are described in section V.D above.

E. Unfunded Mandates Reform Act (UMRA)

    This action does not contain any unfunded mandate of $100 million 
or more as described in UMRA, 2 U.S.C. 1531-1538. The action imposes no 
enforceable duty on any state, local, or tribal governments or the 
private sector.

F. Executive Order 13132: Federalism

    This action 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.

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

    This action does not have tribal implications as specified in 
Executive Order 13175. It will not have substantial direct effects on 
tribal governments, on the relationship between the federal government 
and Indian tribes, or on the distribution of power and responsibilities 
between the federal government and Indian tribes. No tribal governments 
own facilities subject to the NESHAP. Thus, Executive Order 13175 does 
not apply to this action.

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

    This action is not subject to Executive Order 13045 because it is 
not economically significant as defined in Executive Order 12866, and 
because the EPA does not believe the environmental health risks or 
safety risks addressed by this action present a disproportionate risk 
to children. This action's health and risk assessments are contained in 
sections III and IV of this preamble and further documented in the risk 
report titled Residual Risk Assessment for the Paper and Other Web 
Source Category in Support of the 2020 Risk and Technology Review Final 
Rule, which can be found in the docket for this action (Docket ID No. 
EPA-HQ-OAR-2018-0416).

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

    This action is not subject to Executive Order 13211 because it is 
not a significant regulatory action under Executive Order 12866.

J. National Technology Transfer and Advancement Act (NTTAA) and 1 CFR 
Part 51

    This action involves technical standards. The EPA is finalizing the 
following six VCS as alternatives to EPA Method 24 and is incorporating 
them by reference for the first time in the finalized amendments:
     ASTM D2369-10 (Reapproved 2015)\e\, ``Standard Test Method 
for Volatile Content of Coatings.'' This test method describes a 
procedure used for the determination of the weight percent volatile 
content of solvent-borne and waterborne coatings.
     ASTM D2697-03 (Reapproved 2014), ``Standard Test Method 
for Volume Nonvolatile Matter in Clear or Pigmented Coatings.'' This 
test method is applicable to the determination of the volume of 
nonvolatile matter in coatings.
     ASTM D3960-98, ``Standard Practice for Determining 
Volatile Organic Compound (VOC) Content of Paints and Related 
Coatings.'' This test method is used for the measurement of the VOC 
content of solvent borne and waterborne paints and related coatings. 
This method is an acceptable alternative to EPA Method 24 because the 
regulation allows for the use of VOC content as a surrogate for HAP.
     ASTM D6093-97 (Reapproved 2016), ``Standard Test Method 
for Percent Volume Nonvolatile Matter in Clear or Pigmented Coatings 
Using a Helium Gas Pycnometer.'' This test method is used for the 
determination of the percent volume nonvolatile matter in clear and 
pigmented coatings.
     ASTM D2111-10 (Reapproved 2015), ``Standard Test Methods 
for Specific Gravity of Halogenated Organic Solvents and Their 
Admixtures.'' This test method is used for the determination of the 
specific gravity of halogenated organic solvents and solvent 
admixtures.
     ASTM D1963-85 (Reapproved 1996), ``Standard Test Method 
for Specific Gravity of Drying Oils, Varnishes, Resins, and Related 
Materials at 25[deg] C.'' This test method is used for the 
determination of the specific gravity of drying oils, varnishes, alkyd 
resins, fatty acids, and related materials. This method is an 
acceptable alternative to EPA Method 24 for density only and may not be 
valid for all coatings and is valid at the designated temperature (25 
degrees Celsius). This standard was withdrawn in 2004 with no 
replacement; there is no later version.
    These standards are reasonably available from the American Society 
for Testing and Materials (ASTM), 100 Barr Harbor Drive, Post Office 
Box C700, West Conshohocken, PA 19428-2959. See https://www.astm.org/.
    While the EPA has identified another 19 VCS as being potentially 
applicable to this NESHAP, we have decided not to use these VCS in this 
rulemaking. The use of these VCS would not be practical due to lack of 
equivalency, documentation, validation date, and other important 
technical and policy considerations. See the memorandum titled 
Voluntary Consensus Standard Results for National Emission Standards 
for Hazardous Air Pollutants: Paper and Other Web Coating, in the 
docket for this rule for the reasons for these determinations (Docket 
ID Item No. EPA-HQ-OAR-2018-0416-0068).
    The revised regulatory text references ANSI/ASME PTC 19.10-1981 (40 
CFR 63.3360) and ASTM D5087-02 (40 CFR 63.3165). These standards were 
previously approved for this section. That approval continues without 
change.
    Under 40 CFR 63.7(f) and 40 CFR 63.8(f) of subpart A of the General 
Provisions, a source may apply to the EPA for permission to use 
alternative test methods or alternative monitoring requirements in 
place of any required testing methods, performance specifications, or 
procedures in the final rule or any amendments.

K. Executive Order 12898: Federal Actions To Address Environmental 
Justice in Minority Populations and Low-Income Populations

    The EPA believes that this action does not have disproportionately 
high and adverse human health or environmental effects on minority 
populations, low income populations, and/or indigenous peoples, as 
specified in Executive Order 12898 (59 FR 7629, February 16, 1994). The 
documentation for this decision is

[[Page 41295]]

contained in section V.F of this preamble and the technical report, 
Risk and Technology Review--Analysis of Demographic Factors for 
Populations Living Near Paper and Other Web Coating Facilities, which 
is available in the docket for this action (Docket ID No. EPA-HQ-OAR-
2018-0416).

L. Congressional Review Act (CRA)

    This action is subject to the CRA, and the EPA will submit a rule 
report to each House of the Congress and to the Comptroller General of 
the United States. This action is not a ``major rule'' as defined by 5 
U.S.C. 804(2).

3. Section 63.3300 is amended by:
0
a. Revising the introductory text and paragraphs (a), (b), (d), (e) and 
(f); and
0
b. Adding paragraphs (h) through (j).
    The revisions and additions read as follows:


Sec.  63.3300   Which of my emission sources are affected by this 
subpart?

    The affected source subject to this subpart is the collection of 
all web coating lines at your facility. This includes web coating lines 
engaged in the coating of metal webs that are used in flexible 
packaging, and web coating lines engaged in the coating of fabric 
substrates for use in pressure sensitive tape and abrasive materials. 
Web coating lines specified in paragraphs (a) through (g) of this 
section are not part of the affected source of this subpart.
    (a) Any web coating line that is stand-alone equipment under 
subpart KK of this part (National Emission Standards for Hazardous Air 
Pollutants (NESHAP) for the Printing and Publishing Industry) which the 
owner or operator includes in the affected source under subpart KK.
    (b) Any web coating line that is a product and packaging 
rotogravure or wide-web flexographic press under subpart KK of this 
part (NESHAP for the Printing and Publishing Industry) which is 
included in the affected source under subpart KK.
* * * * *
    (d) Any web coating line subject to subpart EE of this part (NESHAP 
for Magnetic Tape Manufacturing Operations).
    (e) Any web coating line subject to subpart SSSS of this part 
(NESHAP for Surface Coating of Metal Coil).
    (f) Any web coating line subject to subpart OOOO of this part 
(NESHAP for the Printing, Coating, and Dyeing of Fabrics and Other 
Textiles). This includes any web coating line that coats both a paper 
or other web substrate and a fabric or other textile substrate, except 
for a fabric substrate used for pressure sensitive tape and abrasive 
materials.
* * * * *
    (h) Any web coating line that coats both paper or a web, and 
another substrate such as fabric, may comply with the subpart of this 
part that applies to the predominant activity conducted on the affected 
source. Predominant activity for this subpart is 90 percent of the mass 
of substrate coated during the compliance period. For example, a web 
coating line that coats 90 percent or more of a paper substrate, and 10 
percent or less of a fabric or other textile substrate, would be 
subject to this subpart and not subpart OOOO of this part. You may use 
data for any reasonable time period of at least one year in determining 
the relative amount of coating activity, as long as they are expected 
to represent the way the source will continue to operate in the future. 
You must demonstrate and document the predominant activity annually.
    (i) Any web coating line subject to this part that is modified to 
include printing activities, may continue to demonstrate compliance 
with this part, in lieu of demonstrating compliance with subpart KK of 
this part. Any web coating line with product and packaging rotogravure 
print station(s) and/or a wide-web flexographic print station(s) that 
is subject to this subpart may elect to continue demonstrating 
compliance with this subpart in lieu of subpart KK of this part, if the 
mass of the materials applied to the line's print station(s) in

[[Page 41296]]

a month ever exceed 5 percent of the total mass of materials applied 
onto the line during the same period.
    (j) If all of the subject web coating lines at your facility 
utilize non-HAP coatings, you can become exempt from the reporting 
requirements of this subpart, provided you submit a one-time report as 
required in Sec.  63.3370(s) to your permitting authority documenting 
the use of only non-HAP coatings.

0
4. Section 63.3310 is amended by revising the definitions of ``coating 
material(s)'' and ``web coating line'' to read as follows:


Sec.  63.3310   What definitions are used in this subpart?

* * * * *
    Coating material(s) means all liquid or semi-liquid materials 
(including the solids fraction of those materials as applied), such as 
inks, varnishes, adhesives (including hot melt adhesives or other hot 
melt materials), primers, solvents, reducers, and other materials 
applied to a substrate via a web coating line. Materials used to form a 
substrate or applied via vapor deposition, and dry abrasive materials 
deposited on top of a coated web, are not considered coating materials.
* * * * *
    Web coating line means any number of work stations, of which one or 
more applies a continuous layer of liquid or semi-liquid coating 
material across the entire width or any portion of the width of a web 
substrate, and any associated curing/drying equipment between an unwind 
or feed station and a rewind or cutting station.
* * * * *

0
5. Section 63.3320 is amended by revising paragraphs (b) introductory 
text and (b)(4) to read as follows:
    The revisions read as follows:


Sec.  63.3320   What emission standards must I meet?

* * * * *
    (b) You must limit organic HAP emissions to the level specified in 
paragraph (b)(1), (2), (3), or (4) of this section for all periods of 
operation, including startup, shutdown, and malfunction (SSM).
* * * * *
    (4) If you use an oxidizer to control organic HAP emissions, 
operate the oxidizer such that an outlet organic HAP concentration of 
no greater than 20 parts per million by volume (ppmv) on a dry basis is 
achieved and the efficiency of the capture system is 100 percent.
* * * * *

0
6. Section 63.3321 is amended by revising paragraph (a) to read as 
follows:


Sec.  63.3321   What operating limits must I meet?

    (a) For any web coating line or group of web coating lines for 
which you use add-on control devices to demonstrate compliance with the 
emission standards in Sec.  63.3320, unless you use a solvent recovery 
system and conduct a liquid-liquid material balance, you must meet the 
operating limits specified in Table 1 to this subpart or according to 
paragraph (b) of this section. These operating limits apply to emission 
capture systems and control devices used to demonstrate compliance with 
this subpart, and you must establish the operating limits during the 
performance test according to the requirements in Sec.  63.3360(e)(3). 
You must meet the operating limits at all times after you establish 
them.
* * * * *

0
7. Section 63.3330 is revised to read as follows:


Sec.  63.3330   When must I comply?

    (a) For affected sources which commenced construction or 
reconstruction prior to September 19, 2019, you must comply as follows:
    (1) Before July 9, 2021, the affected coating operation(s) must be 
in compliance with the applicable emission limit in Sec.  63.3320 at 
all times, except during periods of SSM. On and after July 9, 2021, the 
affected coating operation(s) must be in compliance with the applicable 
emission limit in Sec.  63.3320 at all times, including periods of SSM.
    (2) A periodic emissions performance test must be performed by July 
9, 2023, or within 60 months of the previous test, whichever is later, 
and subsequent tests no later than 60 months thereafter, as required in 
Sec.  63.3360. Performance testing for HAP or VOC destruction 
efficiency required by state agencies can be used to meet this 
requirement.
    (3) After July 9, 2021, you must electronically submit initial 
notifications, notifications of compliance status, performance 
evaluation reports, and performance test reports, as required in Sec.  
63.3400. Semiannual compliance reports must be submitted electronically 
for the first full semiannual compliance period after the template has 
been available in the Compliance and Emissions Data Reporting Interface 
(CEDRI) for 1 year.
    (b) For new affected sources which commenced construction or 
reconstruction after September 19, 2019, you must comply as indicated 
in paragraphs (b)(1) through (3) of this section. Existing affected 
sources which have undergone reconstruction as defined in Sec.  63.2 
are subject to the requirements for new affected sources. The costs 
associated with the purchase and installation of air pollution control 
equipment are not considered in determining whether the existing 
affected source has been reconstructed. Additionally, the costs of 
retrofitting and replacing of equipment that is installed specifically 
to comply with this subpart are not considered reconstruction costs.
    (1) The coating operation(s) must be in compliance with the 
applicable emission limit in Sec.  63.3320 at all times, including 
periods of SSM, starting July 9, 2020, or immediately upon startup, 
whichever is later.
    (2) You must complete any initial performance test required in 
Sec.  63.3360 within the time limits specified in Sec.  63.7(a)(2), and 
subsequent tests no later than 60 months thereafter.
    (3) You must electronically submit initial notifications, 
notifications of compliance status, performance evaluation reports, and 
performance test reports as required in Sec.  63.3400 starting July 9, 
2020, or immediately upon startup, whichever is later. Semiannual 
compliance reports must be submitted electronically for the first full 
semiannual compliance period after the template has been available in 
CEDRI for 1 year.

0
8. Section 63.3340 is revised to read as follows:


Sec.  63.3340   What general requirements must I meet to comply with 
the standards?

    (a) Before July 9, 2021, for each existing source for which 
construction or reconstruction commenced on or before September 19, 
2019, you must be in compliance with the emission limits and operating 
limits in this subpart at all times, except during periods of SSM. On 
and after July 9, 2021, for each such source you must be in compliance 
with the emission limits and operating limits in this subpart at all 
times. For new and reconstructed sources for which construction or 
reconstruction commenced after September 19, 2019, you must be in 
compliance with the emission limits and operating limits in this 
subpart at all times, starting July 9, 2020, or immediately upon 
startup, whichever is later.
    (b) For affected sources as of September 19, 2019, before July 9, 
2021, you must always operate and maintain your affected source, 
including all air pollution control and monitoring equipment you use 
for purposes of complying with this subpart, according to the 
provisions in Sec.  63.6(e)(1)(i). On

[[Page 41297]]

and after July 9, 2021, for such sources and on July 9, 2020, or 
immediately upon startup, whichever is later, for new or reconstructed 
affected sources, you must always operate and maintain your affected 
source, including associated air pollution control equipment and 
monitoring equipment, in a manner consistent with safety and good air 
pollution control practices for minimizing emissions. The general duty 
to minimize emissions does not require the owner or operator to make 
any further efforts to reduce emissions if levels required by the 
applicable standard have been achieved. Determination of whether a 
source is operating in compliance with operation and maintenance 
requirements will be based on information available to the 
Administrator which may include, but is not limited to, monitoring 
results, review of operation and maintenance procedures, review of 
operation and maintenance records, and inspection of the source.
    (c) You must conduct each performance test required by Sec.  
63.3360 according to the requirements in Sec.  63.3360(e)(2) and under 
the conditions in this section unless you obtain a waiver of the 
performance test according to the provisions in Sec.  63.7(h).
    (1) Representative coating operation operating conditions. You must 
conduct the performance test under representative operating conditions 
for the coating operation. Operations during periods of startup, 
shutdown, and nonoperation do not constitute representative conditions. 
You may not conduct performance tests during periods of malfunction. 
You must record the process information that is necessary to document 
operating conditions during the test and explain why the conditions 
represent normal operation. Upon request, you shall make available to 
the Administrator such records as may be necessary to determine the 
conditions of performance tests.
    (2) Representative emission capture system and add-on control 
device operating conditions. You must conduct the performance test when 
the emission capture system and add-on control device are operating at 
a representative flow rate, and the add-on control device is operating 
at a representative inlet concentration. Representative conditions 
exclude periods of startup and shutdown. You may not conduct 
performance tests during periods of malfunction. You must record 
information that is necessary to document emission capture system and 
add-on control device operating conditions during the test and explain 
why the conditions represent normal operation.
    (d) Table 2 to this subpart specifies the provisions of subpart A 
of this part that apply if you are subject to subpart JJJJ.

c. Adding new paragraph (e)(5); and
0
d. Revising newly redesignated paragraph (e)(10).
    The revisions and addition read as follows:


Sec.  63.3350   If I use a control device to comply with the emission 
standards, what monitoring must I do?

* * * * *
    (b) Following the date on which the initial or periodic performance 
test of a control device is completed to demonstrate continuing 
compliance with the standards, you must monitor and inspect each 
capture system and each control device used to comply with Sec.  
63.3320. You must install and operate the monitoring equipment as 
specified in paragraphs (c) and (f) of this section.
    (c) Bypass and coating use monitoring. If you own or operate web 
coating lines with intermittently-controlled work stations, you must 
monitor bypasses of the control device and the mass of each coating 
material applied at the work station during any such bypass. If using a 
control device for complying with the requirements of this subpart, you 
must demonstrate that any coating material applied on a never-
controlled work station or an intermittently-controlled work station 
operated in bypass mode is allowed in your compliance demonstration 
according to Sec.  63.3370(o) and (p). The bypass monitoring must be 
conducted using at least one of the procedures in paragraphs (c)(1) 
through (4) of this section for each work station and associated dryer.
* * * * *
    (d) * * *
    (1) * * *
    (iii) You must have valid data from at least 90 percent of the 
hours when the process is operated. Invalid or missing data should be 
reported as a deviation in the semiannual compliance report.
* * * * *
    (e) Continuous parameter monitoring system (CPMS). If you are using 
a control device to comply with the emission standards in Sec.  
63.3320, you must install, operate, and maintain each CPMS specified in 
paragraphs (e)(10) and (11) and (f) of this section according to the

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

    (b) Control Device. If you are using a control device to comply 
with the emission standards in Sec.  63.3320, you are not required to 
conduct a performance test to demonstrate compliance if one or more of 
the criteria in paragraphs (b)(1) through (3) of this section are met.
    (1) The control device is equipped with continuous emission 
monitoring systems (CEMS) for determining inlet and outlet total 
organic volatile matter concentration and meeting the requirements of 
Performance Specification 6, 8, or 9 in Appendix B to 40 CFR Part 60 
and capture efficiency

[[Page 41299]]

has been determined in accordance with the requirements of this subpart 
such that an overall organic HAP control efficiency can be calculated, 
and the CEMS are used to demonstrate continuous compliance in 
accordance with Sec.  63.3350; or
    (2) You have met the requirements of Sec.  63.7(h) (for waiver of 
performance testing); or
    (3) The control device is a solvent recovery system and you comply 
by means of a monthly liquid-liquid material balance.
    (c) * * *
    (1) * * *
    (i) Include each organic HAP determined to be present at greater 
than or equal to 0.1 mass percent for Occupational Safety and Health 
Administration (OSHA)-defined carcinogens as specified in section A.6.4 
of appendix A to 29 CFR 1910.1200 and greater than or equal to 1.0 mass 
percent for other organic HAP compounds.
* * * * *
    (2) Method 24. For coatings, determine the volatile organic content 
as mass fraction of nonaqueous volatile matter and use it as a 
substitute for organic HAP using Method 24 of appendix A-7 to 40 CFR 
part 60. The Method 24 determination may be performed by the 
manufacturer of the coating and the results provided to you. One of the 
voluntary consensus standards in paragraphs (c)(2)(i) through (v) of 
this section may be used as an alternative to using Method 24.
    (i) ASTM D1963-85 (Reapproved 1996), (incorporated by reference, 
see Sec.  63.14);
    (ii) ASTM D2111-10 (Reapproved 2015), (incorporated by reference, 
see Sec.  63.14);
    (iii) ASTM D2369-10 (Reapproved 2015)\e\, (incorporated by 
reference, see Sec.  63.14);
    (iv) ASTM D2697-03 (Reapproved 2014), (incorporated by reference, 
see Sec.  63.14); and
    (v) ASTM D6093-97 (Reapproved 2016), (incorporated by reference, 
see Sec.  63.14).
    (3) Formulation data. You may use formulation data to determine the 
organic HAP mass fraction of a coating material. Formulation data may 
be provided to the owner or operator by the manufacturer of the 
material. In the event of an inconsistency between Method 311 (appendix 
A to this part) test data and a facility's formulation data, and the 
Method 311 test value is higher, the Method 311 data will govern. 
Formulation data may be used provided that the information represents 
all organic HAP present at a level equal to or greater than 0.1 percent 
for OSHA-defined carcinogens as specified in section A.6.4 of appendix 
A to 29 CFR 1910.1200 and equal to or greater than 1.0 percent for 
other organic HAP compounds in any raw material used.
    (4) As-applied organic HAP mass fraction. If the as-purchased 
coating material is applied to the web without any solvent or other 
material added, then the as-applied organic HAP mass fraction is equal 
to the as-purchased organic HAP mass fraction. Otherwise, the as-
applied organic HAP mass fraction must be calculated using Equation 4 
of Sec.  63.3370.
    (d) * * *
    (1) Method 24. You may determine the volatile organic and coating 
solids mass fraction of each coating applied using Method 24 (appendix 
A-7 to 40 CFR part 60). The Method 24 determination may be performed by 
the manufacturer of the material and the results provided to you. When 
using volatile organic compound content as a surrogate for HAP, you may 
also use ASTM D3960-98, (incorporated by reference, see Sec.  63.14) as 
an alternative to Method 24. If these values cannot be determined using 
either of these methods, you must submit an alternative technique for 
determining their values for approval by the Administrator.
    (2) Formulation data. You may determine the volatile organic 
content and coating solids content of a coating material based on 
formulation data and may rely on volatile organic content data provided 
by the manufacturer of the material. In the event of any inconsistency 
between the formulation data and the results of Method 24 of appendix 
A-7 to 40 CFR part 60 and the Method 24 results are higher, the results 
of Method 24 will govern.
    (3) As-applied volatile organic content and coating solids content. 
If the as-purchased coating material is applied to the web without any 
solvent or other material added, then the as-applied volatile organic 
content is equal to the as-purchased volatile content and the as-
applied coating solids content is equal to the as-purchased coating 
solids content. Otherwise, the as-applied volatile organic content must 
be calculated using Equation 5 to Sec.  63.3370(c)(4) and the as-
applied coating solids content must be calculated using Equation 6 to 
Sec.  63.3370(d).
    (e) * * *
    (1) Initial performance test. An initial performance test to 
establish the destruction or removal efficiency of the control device 
used to comply with the emission standards in Sec.  63.3320 must be 
conducted such that control device inlet and outlet testing is 
conducted simultaneously, and the data are reduced in accordance with 
the test methods and procedures in paragraphs (e)(1)(i) through (ix) of 
this section. You must conduct three test runs as specified in Sec.  
63.7(e)(3), and each test run must last at least 1 hour.
    (i) Method 1 or 1A of appendix A-1 to 40 CFR part 60 must be used 
for sample and velocity traverses to determine sampling locations.
    (ii) Method 2, 2A, 2C, 2D, or 2F of appendix A-1 to 40 CFR part 60, 
or Method 2G of appendix A-2 to 40 CFR part 60 must be used to 
determine gas volumetric flow rate.
    (iii) Method 3, 3A, or 3B of appendix A-2 to 40 CFR part 60 must be 
used for gas analysis to determine dry molecular weight. You may also 
use as an alternative to Method 3B the manual method for measuring the 
oxygen, carbon dioxide, and carbon monoxide content of exhaust gas in 
ANSI/ASME PTC 19.10-1981 Part 10, (incorporated by reference, see Sec.  
63.14).
    (iv) Method 4 of appendix A-3 to 40 CFR part 60 must be used to 
determine stack gas moisture.
    (v) Methods for determining the gas volumetric flow rate, dry 
molecular weight, and stack gas moisture must be performed, as 
applicable, during each test run.
    (vi) Method 25 or 25A of appendix A-7 to 40 CFR part 60 must be 
used to determine total gaseous non-methane organic matter 
concentration. Use the same test method for both the inlet and outlet 
measurements which must be conducted simultaneously. You must submit 
notice of the intended test method to the Administrator for approval 
along with notification of the performance test required under Sec.  
63.7(b). You must use Method 25A if any of the conditions described in 
paragraphs (e)(1)(vi)(A) through (D) of this section apply to the 
control device.
    (A) The control device is not an oxidizer.
    (B) The control device is an oxidizer but an exhaust gas volatile 
organic matter concentration of 50 ppmv or less is required to comply 
with the emission standards in Sec.  63.3320; or
    (C) The control device is an oxidizer but the volatile organic 
matter concentration at the inlet to the control system and the 
required level of control are such that they result in exhaust gas 
volatile organic matter concentrations of 50 ppmv or less; or
    (D) The control device is an oxidizer but because of the high 
efficiency of the control device the anticipated volatile organic 
matter concentration at the

[[Page 41300]]

control device exhaust is 50 ppmv or less, regardless of inlet 
concentration.
    (vii) Except as provided in Sec.  63.7(e)(3), each performance test 
must consist of three separate runs with each run conducted for at 
least 1 hour under the conditions that exist when the affected source 
is operating under normal operating conditions. For the purpose of 
determining volatile organic compound concentrations and mass flow 
rates, the average of the results of all the runs will apply.
    (viii) Volatile organic matter mass flow rates must be determined 
for each run specified in paragraph (e)(1)(vii) of this section using 
Equation 1:
[GRAPHIC] [TIFF OMITTED] TR09JY20.023

Where:

Mf = Total organic volatile matter mass flow rate, 
kilograms (kg)/hour (h).
Qsd = Volumetric flow rate of gases entering or exiting 
the control device, as determined according to paragraph (e)(1)(ii) 
of this section, dry standard cubic meters (dscm)/h.
Cc = Concentration of organic compounds as carbon, ppmv.
12.0 = Molecular weight of carbon.
0.0416 = Conversion factor for molar volume, kg-moles per cubic 
meter (mol/m\3\) (@293 Kelvin (K) and 760 millimeters of mercury 
(mmHg)).

    (ix) For each run, emission control device destruction or removal 
efficiency must be determined using Equation 2:
[GRAPHIC] [TIFF OMITTED] TR09JY20.000

Where:

E = Organic volatile matter control efficiency of the control 
device, percent.
Mfi = Organic volatile matter mass flow rate at the inlet 
to the control device, kg/h.
Mfo = Organic volatile matter mass flow rate at the 
outlet of the control device, kg/h.

    (x) The control device destruction or removal efficiency is 
determined as the average of the efficiencies determined in the test 
runs and calculated in Equation 2.
    (2) Process information. You must record such process information 
as may be necessary to determine the conditions in existence at the 
time of the performance test. Representative conditions exclude periods 
of startup and shutdown. You may not conduct performance tests during 
periods of malfunction. You must record the process information that is 
necessary to document operating conditions during the test and include 
in such record an explanation to support that such conditions represent 
normal operation. Upon request, you shall make available to the 
Administrator such records as may be necessary to determine the 
conditions of performance tests.
    (3) Operating limits. If you are using one or more add-on control 
device other than a solvent recovery system for which you conduct a 
liquid-liquid material balance to comply with the emission standards in 
Sec.  63.3320, you must establish the applicable operating limits 
required by Sec.  63.3321. These operating limits apply to each add-on 
emission control device, and you must establish the operating limits 
during the performance test required by paragraph (e) of this section 
according to the requirements in paragraphs (e)(3)(i) and (ii) of this 
section.
    (i) Thermal oxidizer. If your add-on control device is a thermal 
oxidizer, establish the operating limits according to paragraphs 
(e)(3)(i)(A) and (B) of this section.
    (A) During the performance test, you must monitor and record the 
combustion temperature at least once every 15 minutes during each of 
the three test runs. You must monitor the temperature in the firebox of 
the thermal oxidizer or immediately downstream of the firebox before 
any substantial heat exchange occurs.
    (B) Use the data collected during the performance test to calculate 
and record the average combustion temperature maintained during the 
performance test. Maintain the 3-hour average combustion temperature no 
more than 50 degrees Fahrenheit lower than this average combustion 
temperature.
    (ii) Catalytic oxidizer. If your add-on control device is a 
catalytic oxidizer, establish the operating limits according to 
paragraphs (e)(3)(ii)(A) and (B) or paragraphs (e)(3)(ii)(C) and (D) of 
this section.
    (A) During the performance test, you must monitor and record the 
temperature just before the catalyst bed and the temperature difference 
across the catalyst bed at least once every 15 minutes during each of 
the three test runs.
    (B) Use the data collected during the performance test to calculate 
and record the average temperature just before the catalyst bed and the 
average temperature difference across the catalyst bed maintained 
during the performance test. Maintain the 3-hour average combustion 
temperature no more than 50 degrees Fahrenheit lower than this average 
combustion temperature or maintain the 3-hour average temperature 
difference across the catalyst bed at no less than 80 percent of this 
average temperature differential, provided that the minimum temperature 
is always 50 degrees Fahrenheit above the catalyst's ignition 
temperature.
    (C) As an alternative to monitoring the temperature difference 
across the catalyst bed, you may monitor the temperature at the inlet 
to the catalyst bed and implement a site-specific inspection and 
maintenance plan for your catalytic oxidizer as specified in paragraph 
(e)(3)(ii)(D) of this section. During the performance test, you must 
monitor and record the temperature just before the catalyst bed at 
least once every 15 minutes during each of the three test runs. Use the 
data collected during the performance test to calculate and record the 
average temperature just before the catalyst bed during the performance 
test. Maintain the 3-hour average combustion temperature no more than 
50 degrees Fahrenheit lower than this average combustion temperature.
    (D) You must develop and implement an inspection and maintenance 
plan for your catalytic oxidizer(s) for which you elect to monitor 
according to paragraph (e)(3)(ii)(C) of this section. The plan must 
address, at a minimum, the elements specified in paragraphs 
(e)(3)(ii)(D)(1) through (3) of this section.

    (1) Annual sampling and analysis of the catalyst activity (i.e., 
conversion efficiency) following the manufacturer's or catalyst 
supplier's recommended procedures,
    (2) Monthly inspection of the oxidizer system including the burner 
assembly and fuel supply lines for problems, and
    (3) Annual internal and monthly external visual inspection of the 
catalyst bed to check for channeling, abrasion, and settling. If 
problems are found, you must take corrective action consistent with the 
manufacturer's recommendations and conduct a new performance test to 
determine destruction efficiency in accordance with this section.
    (4) Control Destruction Efficiency Curve Development. If you are 
using one or more add-on control devices other than a solvent recovery 
system for which you conduct a liquid-liquid material balance to comply 
with the emission standards in Sec.  63.3320, you may establish a 
control destruction efficiency curve for use in estimating emissions 
that occur during deviations of the 3-hour operating parameters. This 
curve can be generated using test data or manufacturer's data that 
specifically documents the level of control at varying temperatures for 
your control device.
    (f) Capture efficiency. If you demonstrate compliance by meeting 
the requirements of Sec.  63.3370(f), (g), (h), (i), (j)(2), (l), 
(o)(2) or (3), or (q), you must determine capture efficiency using the 
procedures in paragraph (f)(1), (2), or (3) of this section, as 
applicable.

    (g) Volatile matter retained in the coated web or otherwise not 
emitted to the atmosphere. You may choose to take into account the mass 
of volatile matter retained in the coated web after curing or drying or 
otherwise not emitted to the atmosphere when determining compliance 
with the emission standards in Sec.  63.3320. If you choose this 
option, you must develop a site- and product-specific emission factor 
(EF) and determine the amount of volatile matter retained in the coated 
web or otherwise not emitted using Equation 3 to Sec.  63.3360(g)(1). 
The EF must be developed by conducting a performance test using an 
approved EPA test method, or alternative approved by the Administrator 
by obtaining the average of a three-run test. You may additionally use 
manufacturer's emissions test data (as long as it replicates the 
facility's coating formulation and operating conditions), or a mass-
balance type approach using a modified Method 24 (including ASTM D5403-
93 for radiation-cureable coatings). The EF should equal the proportion 
of the mass of volatile organics emitted to the mass of volatile 
organics in the coating materials evaluated. You may use the EF in your 
compliance calculations only for periods that the work station(s) was 
(were) used to make the product, or a similar product, corresponding to 
that produced during the performance test. You must develop a separate 
EF for each group of different products that you choose to utilize an 
EF for calculating emissions by conducting a separate performance test 
for that group of products. You must conduct a periodic performance 
test to re-establish the EF if there is a change in coating 
formulation, operating conditions, or other change that could 
reasonably be expected to increase emissions since the time of the last 
test that was used to establish the EF.
    (1) Calculate the mass of volatile organics retained in the coated 
web or otherwise not emitted for the month from each group of similar 
products using Equation 3:
[GRAPHIC] [TIFF OMITTED] TR09JY20.018

Where:

Mvret = Mass of volatile matter retained in the coated 
web after curing or drying, or otherwise not emitted to the 
atmosphere, kg.
Cvi = Volatile organic content of coating material, i, 
expressed as a mass fraction, kg/kg.
Mi = Mass of as-purchased coating material, i, applied in 
a month, kg.
q = Number of different materials added to the coating material.
Cvij = Volatile organic content of material, j, added to 
as-purchased coating material, i, expressed as a mass fraction, kg/
kg.
Mij = Mass of material, j, added to as-purchased coating 
material, i, in a month, kg.
EFi = Volatile organic matter site- and product-specific 
emission factor (three-run average determined from performance 
testing, evaluated as proportion of mass volatile organics emitted 
to mass of volatile organics in the coatings used during the 
performance test).

Sec.  63.3370  How do I demonstrate compliance with the emission 
standards?

    You must demonstrate compliance each month with the emission 
limitations in Sec.  63.3320(b)(1) through (4). For each monthly 
demonstration, you may apply any combination of the emission 
limitations to each of your web coating lines individually, to each of 
one or more groupings of your lines (including a single grouping 
encompassing all lines of your affected source), or to any combination 
of individual and grouped lines, so long as each web coating line is 
included in the compliance demonstration for the month (i.e., you are 
not required to apply the same emission limitation to each of the 
individual lines or groups of lines). You may change the emission 
limitation that you apply each month to your individual or grouped 
lines, and you may change line groupings for your monthly compliance 
demonstration.
    (a) A summary of how you must demonstrate compliance follows:

specific emission factor. Details regarding the test methods and 
calculations are provided in Sec.  63.3360(g).
    (f) Capture and control to reduce emissions to no more than 
allowable limit (Sec.  63.3320(b)(1)). Operate a capture system and 
control device and demonstrate an overall organic HAP control 
efficiency of at least 95 percent at an existing affected source and at 
least 98 percent at a new affected source for each month, or operate a 
capture system and oxidizer so that an outlet organic HAP concentration 
of no greater than 20 ppmv on a dry basis is achieved as long as the 
capture efficiency is 100 percent as detailed in Sec.  63.3320(b)(4). 
Unless one of the cases described in paragraph (f)(1), (2), or (3) of 
this section applies to the affected source, you must either 
demonstrate compliance in accordance with the procedure in paragraph 
(i) of this section when emissions from the affected source are 
controlled by a solvent recovery device, or the procedure in paragraph

demonstrate compliance for a web coating line by operating each capture 
system and each control device and continuous parameter monitoring

and operates more than one capture system or more than one control 
device, you must demonstrate compliance in accordance with the 
provisions of either paragraph (o) or (q) of this section.
    (2) If the affected source operates one or more never-controlled 
work stations or one or more intermittently-controlled work stations, 
you must demonstrate compliance in accordance with the provisions of 
paragraph (o) of this section.
    (3) An alternative method of demonstrating compliance with Sec.  
63.3320(b)(1) is the installation of a PTE around the web coating line 
that

[[Page 41306]]

achieves 100 percent capture efficiency and ventilation of all organic 
HAP emissions from the total enclosure to an oxidizer with an outlet 
organic HAP concentration of no greater than 20 ppmv on a dry basis. If 
this method is selected, you must demonstrate compliance by following 
the procedures in paragraphs (f)(3)(i) and (ii) of this section. 
Compliance is determined according to paragraph (f)(3)(iii) of this 
section.
    (i) Demonstrate that a total enclosure is installed. An enclosure 
that meets the requirements in Sec.  63.3360(f)(1) will be considered a

enclosure is demonstrated and the organic HAP concentration at the 
outlet of the incinerator is demonstrated to be no greater than 20 ppmv 
on a dry basis.

applied limit (Sec.  63.3320(b)(3)). Operate a capture system and 
control device and limit the organic HAP emission rate from an existing 
affected source to no more than 0.20 kg organic HAP emitted per kg 
coating solids applied, and from a new affected source to no more than 
0.08 kg organic HAP emitted per kg coating solids applied as determined 
on a monthly average as-applied basis. If the affected source operates 
more than one capture system, more than one control device, one or more 
never-controlled work stations, or one or more intermittently-
controlled work stations, then you must demonstrate compliance in 
accordance with the provisions of paragraph (o) of this section. 
Otherwise, you must demonstrate compliance following the procedure in 
paragraph (j) of this section when emissions from the affected source 
are controlled by a solvent recovery device or the procedure in 
paragraph (l) of this section when emissions are controlled by an 
oxidizer.

63.3320(b)(2)). Operate a capture system and control device and limit 
the organic HAP emission rate to no more than 0.04 kg organic HAP 
emitted per kg coating material applied at an existing affected source, 
and no more than 0.016 kg organic HAP emitted per kg coating material 
applied at a new affected source as determined on a monthly average as-
applied basis. If the affected source operates more than one capture 
system, more than one control device, one or more never-controlled work 
stations, or one or more intermittently-controlled work stations, then 
you must demonstrate compliance in accordance with the provisions of 
paragraph (o) of this section. Otherwise, you must demonstrate 
compliance following the procedure in paragraph (j) of this section 
when emissions from the affected source are controlled by a solvent 
recovery device or the procedure in paragraph (l) of this section when 
emissions are controlled by an oxidizer.
    (i) Capture and control to achieve allowable emission rate. Operate 
a capture system and control device and limit the monthly organic HAP 
emissions to less than the allowable emissions as calculated in 
accordance with paragraph (m) of this section. If the affected source 
operates more than one capture system, more than one control device, 
one or more never-controlled work stations, or one or more 
intermittently-controlled work stations, then you must demonstrate 
compliance in accordance with the provisions of paragraph (o) of this 
section. Otherwise, the owner or operator must demonstrate compliance 
following the procedure in paragraph (j) of this section when emissions 
from the affected source are controlled by a solvent recovery device or 
the procedure in paragraph (l) of this section when emissions are 
controlled by an oxidizer.

allowable organic HAP emissions for use in demonstrating compliance in 
accordance with paragraph (d), (i), (j)(1)(x)(D), (j)(2)(xi)(D), or 
(l)(3)(iv) of this section. You will need to determine the amount of 
coating material applied at greater than or equal to 20 mass percent

per kg coating solids at a new affected source, and coating material 
applied at less than 20 mass percent coating solids complying with 4 
mass percent organic HAP at an existing affected source and 1.6 mass-
percent organic HAP at a new affected source as follows:
    (1) Determine the as-purchased mass of each coating material 
applied each month.
    (2) Determine the as-purchased coating solids content of each 
coating material applied each month in accordance with Sec.  
63.3360(d)(1).
    (3) Determine the as-purchased mass fraction of each coating 
material which was applied at 20 mass percent or greater coating solids 
content on an as-applied basis.
    (4) Determine the total mass of each solvent, diluent, thinner, or 
reducer added to coating materials which were applied at less than 20

    (o) Combinations of capture and control. If you operate more than 
one capture system, more than one control device, one or more never-
controlled work stations, or one or more intermittently-controlled work 
stations,

[[Page 41311]]

you must calculate organic HAP emissions according to the procedures in 
paragraphs (o)(1) through (4) of this section, and use the calculation 
procedures specified in paragraph (o)(5) of this section to convert the 
monitoring and other data into units of the selected control option in 
paragraphs (f) through (i) of this section. Use the procedures 
specified in paragraph (o)(6) of this section to demonstrate 
compliance.
    (1) Solvent recovery system using liquid-liquid material balance 
compliance demonstration. If you choose to comply by means of a liquid-
liquid material balance for each solvent recovery system used to 
control one or more web coating lines, you must determine the organic 
HAP emissions for those web coating lines controlled by that solvent 
recovery system either:
    (i) In accordance with paragraphs (j)(1)(i) through (iii) and (v) 
through (vii) of this section, if the web coating lines controlled by 
that solvent recovery system have only always-controlled work stations; 
or
    (ii) In accordance with paragraphs (j)(1)(ii), (iii), (v), and (vi) 
and (p) of this section, if the web coating lines controlled by that 
solvent recovery system have one or more never-controlled or 
intermittently-controlled work stations.
    (2) Solvent recovery system using performance test compliance 
demonstration and CEMS. To demonstrate compliance through an initial 
test of capture efficiency, continuous monitoring of a capture system 
operating parameter, and a CEMS on each solvent recovery system used to 
control one or more web coating lines, you must:

that capture and control system have only always-controlled work 
stations; or
    (B) In accordance with paragraphs (j)(2)(i) through (iii), (vi), 
and (p) of this section, if the web coating lines served by that 
capture and control system have one or more never-controlled or 
intermittently-controlled work stations.
    (3) Oxidizer. To demonstrate compliance through performance tests 
of capture efficiency and control device efficiency, continuous 
monitoring of capture system, and CPMS for control device operating 
parameters for each oxidizer used to control emissions from one or more 
web coating lines, you must:

section, if the web coating lines served by that capture and control 
system have only always-controlled work stations; or
    (B) In accordance with paragraphs (l)(1)(i) through (iii), (v), and 
(p) of this section, if the web coating lines served by that capture 
and control system have one or more never-controlled or intermittently-
controlled work stations.
    (4) Uncontrolled coating lines. If you own or operate one or more 
uncontrolled web coating lines, you must determine the organic HAP 
applied on those web coating lines using Equation 10. The organic HAP 
emitted from an uncontrolled web coating line is equal to the organic 
HAP applied on that web coating line.
    (5) Convert the information obtained under paragraphs (o)(1) 
through (4) of this section into the units of the selected compliance 
option using the calculation procedures specified in paragraphs

or operator must determine the coating solids content of each coating 
material applied during the month following the procedure in Sec.  
63.3360(d).

of this section were maintained at the values established under 
Sec. Sec.  63.3350 and 63.3360 and one of the standards in paragraphs 
(o)(6)(i) through (iv) of this section were met. If operating parameter 
deviations occurred, the affected source is in compliance with the 
emission standards in Sec.  63.3320(b) for the month if, assuming no 
control of emissions or by estimating the emissions using a control 
destruction efficiency curve for each 3-hour deviation period, one of 
the standards in paragraphs (6)(i) through (iv) of this section were 
met.
    (i) The total mass of organic HAP emitted by the affected source 
based on coating solids applied is no more than 0.20 kg organic HAP per

than 0.08 kg organic HAP per kg coating solids applied at a new 
affected source; or
    (ii) The total mass of organic HAP emitted by the affected source 
based on material applied is no more than 0.04 kg organic HAP per kg

(o)(1)(ii), (o)(2)(ii)(B), or (o)(3)(iii)(B) of this section for 
calculation procedures to determine organic HAP emissions for your 
intermittently-controlled and never-controlled work stations, you must:
    (1) Determine the sum of the mass of all coating materials as-
applied on intermittently-controlled work stations operating in bypass 
mode and the mass of all coating materials as-applied on

[[Page 41312]]

never-controlled work stations during the month.
    (2) Determine the sum of the mass of all coating materials as-
applied on intermittently-controlled work stations operating in a

atmosphere for the compliance demonstration procedures in this 
section.

device efficiency. For each web coating line or group of web coating 
lines for which you use the provisions of paragraph (o)(2)(ii)(B) or

atmosphere for the compliance demonstration procedures in this 
section.

    (q) Always-controlled work stations with more than one capture and 
control system. If you operate more than one capture system or more 
than one control device and only have always-controlled work stations, 
then you are in compliance with the emission standards in Sec.  
63.3320(b)(1) for the month if for each web coating line or group of 
web coating lines controlled by a common control device:
    (1) The volatile matter collection and recovery efficiency as 
determined by paragraphs (j)(1)(i), (iii), (v), and (vi) of this

balance approach in accordance with this section, except for any month 
that you elect to meet the emission limitation in Sec.  63.3320(b)(4). 
The mass-balance approach should be performed as follows:
    (1) Separately for each individual/grouping(s) of lines, you must 
sum the mass of organic HAP emitted during the month and divide by the 
corresponding total mass of all organic HAP applied on the lines, or 
total mass of coating materials applied on the lines, or total mass of 
coating solids applied on the lines, for the same period, in accordance 
with the emission limitation that you have elected at Sec.  
63.3320(b)(1) through (3) for the month's demonstration. You may also 
choose to use volatile organic content as a surrogate for organic HAP 
for the compliance demonstration in accordance with Sec.  63.3360(d). 
You are required to include all emissions and inputs that occur during 
periods that each line or grouping of lines operates in accordance with 
the applicability criteria in Sec.  63.3300.
    (2) You must include all of the organic HAP emitted by your 
individual/grouping(s) of lines, as follows.

[[Page 41313]]

    (i) You must record the mass of organic HAP or volatile organic 
content utilized at all work stations of all of your individually/
grouping(s) of lines. You must additionally record the mass of all 
coating materials applied at these work stations if you are 
demonstrating compliance for the month with the emission limitation at 
Sec.  63.3320(b)(2) (the ``coating materials'' option). You must 
additionally record the mass of all coating solids applied at these 
work stations if you are demonstrating compliance for the month with 
the emission limitation at Sec.  63.3320(b)(3) (the ``coating solids'' 
option).
    (ii) You must assume that all of the organic HAP input to all 
never-controlled work stations is emitted, unless you have determined 
an emission factor in accordance with Sec.  63.3360(g).
    (iii) For all always-controlled work stations, you must assume that 
all of the organic HAP or volatile organic content is emitted, less the 
reductions provided by the corresponding capture system and control 
device, in accordance with the most recently measured capture and 
destruction efficiencies, or in accordance with the measured mass of 
volatile organic compounds (VOC) recovered for the month (e.g., carbon 
control or condensers). You may account for organic HAP or volatile 
organic content retained in the coated web or otherwise not emitted if 
you have determined an emission factor in accordance with Sec.  
63.3360(g).
    (iv) For all intermittently-controlled work stations, you must 
assume that all of the organic HAP or volatile organic content is 
emitted during periods of no control. During periods of control, you 
must assume that all of the organic HAP or volatile organic content is 
emitted, less the reductions provided by the corresponding capture 
system and control device, in accordance with the most recently 
measured capture and destruction efficiencies, or in accordance with 
the measured mass of VOC recovered for the month (e.g., carbon control 
or condensers). You may account for organic HAP or volatile organic 
content retained in the coated web or otherwise not emitted if you have 
determined an emission factor in accordance with Sec.  63.3360(g).
    (v) You must record the organic HAP or volatile organic content 
input to all work stations of your individual/grouping(s) of lines and 
the mass of coating materials and/or solids applied, if applicable, and 
determine corresponding emissions during all periods of operation, 
including malfunctions or startups and shutdowns of any web coating 
line or control device.

63.3320(b) if each of your individual/grouping(s) of lines, meets one 
of the requirements in paragraphs (r)(3)(i) through (iii) of this 
section, as applicable. If operating parameter limit deviations 
occurred, including periods that the oxidizer control device(s), if 
any, operated at an average combustion temperature more than 50 degrees 
Fahrenheit below the temperature established in accordance with Sec.  
63.3360(e), or the 3-hour average temperature difference across the 
catalyst bed at no less than 80 percent of this average temperature 
differential and the catalytic oxidizer maintained a minimum 
temperature 50 degrees Fahrenheit above the catalyst's ignition 
temperature, you are in compliance with the emission standards in Sec.  
63.3320(b) for the month, if assuming no control of emissions for each 
3-hour deviation period (or in accordance with an alternate approved 
method), one of the requirements in paragraphs (r)(3)(i) through (iii) 
of this section was met.
    (i) The total mass of organic HAP emitted by the affected source 
based on HAP applied is no more than 0.05 kg organic HAP per kg HAP 
applied at an existing affected source and no more than 0.02 kg organic 
HAP per kg HAP applied at a new affected source; or
    (ii) The total mass of organic HAP emitted by the affected source 
based on coating solids applied is no more than 0.20 kg organic HAP per 
kg coating solids applied at an existing affected source and no more 
than 0.08 kg organic HAP per kg coating solids applied at a new 
affected source; or
