National Emission Standards for Hazardous Air Pollutants: Iron 
and Steel Foundries Major Source Residual Risk and Technology Review 
and Area Source Technology Review

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: This action finalizes the residual risk and technology review 
(RTR) conducted for the major source Iron and Steel Foundries source 
category and the technology review for the area source Iron and Steel 
Foundries source category regulated under national emission standards 
for hazardous air pollutants (NESHAP). In addition, we are taking final 
action to remove exemptions for periods of startup, shutdown, and 
malfunction (SSM) and to specify that emissions standards apply at all 
times. These final amendments also require electronic reporting of 
performance test results and compliance reports and make minor 
corrections and clarifications to a few other rule provisions for major 
sources and area sources.

DATES: This final rule is effective on September 10, 2020. The 
incorporation by reference of certain publications listed in the rule 
is approved by the Director of the Federal Register as of January 2, 
2008.

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 November 9, 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 
preceding FOR FURTHER INFORMATION CONTACT section, and the Associate 
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 hazardous air pollutants (HAP) from stationary 
sources. In the first stage, we 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

[[Page 56082]]

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. All other sources are ``area sources.'' 
For major sources, these standards are commonly 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, we must also consider control options that are more 
stringent than the floor under CAA section 112(d)(2). We 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. For area 
sources, CAA section 112(d)(5) gives the EPA discretion to set 
standards based on generally available control technologies or 
management practices (GACT standards) in lieu of MACT standards.
    In the second stage of the NESHAP 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, which is applicable to both MACT and GACT standards, 
we 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, 
which is limited to the MACT standards, we 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 MACT 
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 
54394.
---------------------------------------------------------------------------

    \1\ The Court has affirmed this approach of implementing CAA 
section 112(f)(2)(A): NRDC v. EPA, 529 F.3d 1077, 1083 (D.C. 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 are the Iron and Steel Foundries source categories and how do 
the NESHAP regulate HAP emissions from these source categories?

    The EPA promulgated the MACT standards for major source iron and 
steel foundries on April 22, 2004 (69 FR 21906). The standards are 
codified at 40 CFR part 63, subpart EEEEE. The EPA promulgated GACT 
standards for area source iron and steel foundries on January 2, 2008, 
under 40 CFR part 63, subpart ZZZZZ (73 FR 252). Iron and steel 
foundries manufacture metal castings by melting iron and/or steel in a 
furnace, pouring the molten iron or steel into a mold of a desired 
shape, allowing the casting to cool (solidify) in the mold, removing 
the casting from the mold, and finishing (grinding and cleaning) the 
final cast product. There are approximately 45 major source iron and 
steel foundries in the United States and approximately 390 area source 
foundries.
    The MACT standards for major source iron and steel foundries 
established the following: Particulate matter (PM) emission limits (as 
a surrogate for metal HAP) and alternative metal HAP emission limits 
for metal melting furnaces; triethylamine emission limits from phenolic 
urethane cold box mold and core making operations; and organic HAP 
emission limits for new and existing cupola melting furnaces and scrap 
preheaters and for new automated cooling and shakeout lines. The MACT 
standards also included work practice standards prohibiting methanol to 
be used as a specific component of furan (also known as furfuryl 
alcohol) warm box mold and core making lines and instituting scrap 
selection and inspection requirements to limit the amount of mercury, 
lead, chlorinated plastics, and free liquids present in the scrap fed 
to metal melting furnaces. For other ancillary sources at the foundry, 
such as casting finishing, the MACT standards include a building 
opacity limit.
    The GACT standards for area source iron and steel foundries 
established PM emission limits (as a surrogate for metal HAP) and 
alternative metal HAP emission limits for metal melting furnaces at 
``large'' foundries.\2\ The GACT standards for metal melting furnaces 
at area source foundries are less stringent than the MACT standards for 
major source foundries and include an allowance to use emissions 
averaging. Small and large area source iron and steel foundries are 
required to operate according to scrap selection and inspection 
requirements to limit the amount of mercury, lead, chlorinated 
plastics, and free liquids present in the scrap fed to metal melting 
furnaces and to operate furan warm box mold and core making lines 
without the use of methanol as a component of the catalyst formulation.
---------------------------------------------------------------------------

    \2\ Existing area source foundries with annual metal melt 
production exceeding 20,000 tons and new area source foundries with 
annual metal melt capacity exceeding 10,000 tons are defined as 
``large'' foundries; area source foundries at or below these metal 
melt rates are defined as ``small'' foundries.
---------------------------------------------------------------------------

C. What changes did we propose for the Iron and Steel Foundries source 
categories in our October 9, 2019, proposal?

    On October 9, 2019, the EPA published a proposed rule in the 
Federal Register (84 FR 54394) for the Iron and Steel Foundries NESHAP 
for both major and area sources, 40 CFR part 63, subparts EEEEE and 
ZZZZZ, that took into consideration the RTR analyses for major sources 
and the technology review for area sources. In the proposed rule, we 
proposed that the health risks due to HAP emissions from major source 
iron and steel foundries

[[Page 56083]]

are acceptable and that the Iron and Steel Foundries major source 
NESHAP (40 CFR part 63, subpart EEEEE) provides an ample margin of 
safety to protect public health and that additional standards are not 
necessary to prevent an adverse environmental effect. We also proposed 
that no revisions to the Iron and Steel Foundries major source or area 
source NESHAP are necessary based on our technology review. We proposed 
revisions to the SSM provisions of both NESHAP in order to ensure that 
they are consistent with the Court decision in Sierra Club v. EPA, 551 
F. 3d 1019 (D.C. Cir. 2008). We proposed revisions to the recordkeeping 
and reporting requirements of both NESHAP to require the use of 
electronic reporting of performance test reports and semiannual 
reports. We also proposed to correct a section reference error in the 
major source NESHAP (40 CFR part 63, subpart EEEEE) and to correct 
several section reference errors and make other minor editorial 
revisions to the area source NESHAP (40 CFR part 63, subpart ZZZZZ). 
For additional information regarding the proposed rule, see the October 
9, 2019, proposal (84 FR 54394).

III. What is included in these final rules?

    This action finalizes the EPA's determinations pursuant to the RTR 
provisions of CAA section 112 for the Iron and Steel Foundries major 
source category and the CAA technology review provisions for the Iron 
and Steel Foundries area source category. This action also finalizes 
other changes to the NESHAP, including proposed revisions to SSM 
requirements, electronic reporting requirements, and editorial 
corrections. This action also reflects several changes to the October 
2019 proposal in consideration of comments received during the public 
comment period described in section IV of this preamble.

A. What are the final rule amendments based on the risk review for the 
major source Iron and Steel Foundries source category?

    The EPA proposed no changes to Iron and Steel Foundries major 
source NESHAP based on the risk review conducted pursuant to CAA 
section 112(f). In this action, we are finalizing our proposed 
determination that risks from the Iron and Steel Foundries source 
category are acceptable, the standards provide an ample margin of 
safety to protect public health, and more stringent standards are not 
necessary to prevent an adverse environmental effect. The EPA received 
no new data or other information during the public comment period that 
causes us to change that proposed determination. Therefore, we are not 
making any revisions to the existing standards under CAA section 
112(f), and we are readopting the existing standards. Further 
information regarding these decisions are provided in section IV of 
this preamble.

B. What are the final rule amendments based on the technology review 
for the Iron and Steel Foundries source categories?

    We determined that there are no developments in practices, 
processes, and control technologies that necessitate revisions to the 
MACT or GACT standards for these source categories. Therefore, we are 
not finalizing revisions to the MACT or GACT standards under CAA 
section 112(d)(6). The analyses and rationale for these decisions are 
described in section IV of this preamble.

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

    We are finalizing amendments to the major source and area source 
Iron and Steel Foundries NESHAP to remove and revise provisions related 
to SSM consistent with what we proposed (84 FR 54415) except for the 
volatile organic HAP (VOHAP) standards during startup and shutdown for 
cupola melting furnaces at major source iron and steel foundries.\3\ 
With regard to cupola furnaces VOHAP standards, we are removing the SSM 
exemptions consistent with what we proposed, however, with regard to 
the VOHAP emissions standards, we are finalizing work practice 
standards for VOHAP emissions for periods of startup and shutdown based 
on consideration of public comments instead of applying numeric 
emissions limits during these periods, as described in more detail 
below.
---------------------------------------------------------------------------

    \3\ The 20 parts per million by volume (ppmv) VOHAP emission 
limit for cupola melting furnaces applies only to major source iron 
and steel foundries (40 CFR part 63, subpart EEEEE). The area source 
NESHAP only regulates metal HAP emissions from melting furnaces so 
the SSM revisions for 40 CFR part 63, subpart ZZZZZ, are being 
finalized as proposed without exception.
---------------------------------------------------------------------------

    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 (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 
explained in section IV.D.1 of the October 2019 proposal preamble (84 
FR 54415, October 9, 2019), the EPA proposed that the Iron and Steel 
Foundries NESHAP would require that the standards apply at all times, 
consistent with the Court decision in Sierra Club v. EPA, 551 F. 3d 
1019 (D.C. Cir. 2008). Except for cupola melting furnace VOHAP emission 
limits, the EPA is finalizing the SSM provisions as proposed without 
setting a separate standard for startup and shutdown as discussed in 
the October 2019 proposal (84 FR 54415).
    For VOHAP emissions from cupola melting furnaces, the EPA is 
finalizing separate standards during periods of cupola startup and 
shutdown to address public comments received on the proposed rule. 
Specifically, the EPA is finalizing amendments to the 20 ppmv VOHAP 
emission limit to apply only during normal production operations (e.g., 
when furnace is actively producing molten metal), or more specifically, 
what the major source NESHAP refers to as ``on blast'' conditions as 
defined in the rule. With regard to cupola furnace startup and shutdown 
periods, which are considered part of the ``off blast'' conditions in 
the major source NESHAP, the EPA is finalizing work practice standards 
that require compliance with the building opacity limit during initial 
cupola startup procedures (e.g., refractory curing, cupola bed 
preparation, and beginning stage of cupola coke bed preparation) and 
final shutdown procedures (e.g., cooling and cupola banking or bottom 
drop). For other startup, shutdown, and idling periods, the EPA is 
finalizing work practice standards requiring that owners/operators (1) 
begin operating the cupola afterburner or other thermal combustion 
device as soon as practicable after beginning the coke bed preparatory 
step but no later than 30 minutes after the blast air is started to 
begin the coke bed burn-in and (2) operate the afterburner or other 
thermal combustion device with a flame present at all times during 
other off blast periods. Furthermore, we are requiring facilities to 
operate according to procedures to minimize emissions and ensure safety 
during all of these periods as specified in the operation and 
maintenance (O&M) plan. We are finalizing new definitions of ``cupola 
startup'' and ``cupola shutdown'' to

[[Page 56084]]

clarify when these work practice standards apply and adding 
recordkeeping requirements for facilities to demonstrate compliance 
with the new work practice standards. We also added monitoring and 
recordkeeping requirements for foundry owners or operators to 
demonstrate compliance with the new work practice standards. More 
detail regarding these revisions from the proposal are provided in 
section IV.C of this preamble.
    Further, the EPA is not finalizing separate standards for 
malfunctions. We are finalizing provisions in the final rule consistent 
with our proposal with regard to malfunctions (see 84 FR 54415). As 
discussed in the October 2019 proposal preamble, 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.1 of the proposal preamble for further discussion of the EPA's 
rationale for the decision not to set separate 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, given that administrative and judicial procedures for addressing 
exceedances of the standards fully recognize that violations may occur 
despite good faith efforts to comply and can accommodate those 
situations.
    As is explained in more detail below, we are finalizing revisions 
to the General Provisions table to 40 CFR part 63, subparts EEEEE and 
ZZZZZ, to eliminate requirements that include rule language providing 
exemptions for periods of SSM. Additionally, we are 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, we are finalizing our proposal to revise the 
Deviation Notification Report and related records as they relate to 
malfunctions, as described below. As discussed in the October 2019 
proposal preamble, these revisions are consistent with the requirement 
that the standards apply at all times. Refer to sections III.D.1 
through 5 of the October 2019 proposal preamble for a detailed 
discussion of these amendments (see 84 FR 54415).

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

    The EPA is requiring owners or operators of iron and steel 
foundries to submit electronic copies of certain required performance 
test reports, performance evaluation reports, and semiannual reports 
through the EPA's Central Data Exchange using the Compliance and 
Emissions Data Reporting Interface (CEDRI). The final rule requires 
that performance test results and performance evaluation results be 
submitted using the Electronic Reporting Tool. For semiannual reports, 
the final rule requires that owners or operators use the appropriate 
spreadsheet template to submit information to CEDRI. The final version 
of the templates for these reports are located on the CEDRI website.\4\
---------------------------------------------------------------------------

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

    The electronic submittal of the reports addressed in this 
rulemaking 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 the EPA to assess and 
determine compliance, and will ultimately reduce burden on regulated 
facilities, delegated air agencies, and the EPA. Electronic reporting 
also eliminates paper-based, manual processes, thereby saving time and 
resources, simplifying data entry, eliminating redundancies, minimizing 
data reporting errors, and providing data quickly and accurately to the 
affected facilities, air agencies, the EPA and the public. For a more 
thorough discussion of electronic reporting, see the memorandum, 
Electronic Reporting Requirements for New Source Performance Standards 
(NSPS) and National Emission Standards for Hazardous Air Pollutants 
(NESHAP) Rules, available in Docket ID No. EPA-HQ-OAR-2019-0373.

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

    We proposed that all of the SSM revisions would become effective 
upon promulgation. The SSM revisions to the area source NESHAP being 
promulgated in this action are effective on September 10, 2020, as 
proposed. The SSM revisions to the General Provisions table in major 
source NESHAP (Table 1 to subpart EEEEE of part 63) being promulgated 
in this action are also effective on September 10, 2020, as proposed. 
However, as previously noted in section III.C of this preamble, we are 
finalizing new work practice standards specific to cupola startup and 
shutdown. Therefore, we are providing 180 days for facilities to 
transition to these new requirements and retaining specific provisions 
within the major source NESHAP at 40 CFR 63.7720 regarding SSM for this 
180-day transition period. As proposed, we are also providing 180 days 
for facilities to transition to the electronic reporting requirements. 
As such, revisions for selected SSM provisions and for the electronic 
reporting requirements being promulgated in this action are effective 
on March 9, 2021.

IV. What is the rationale for our final decisions and amendments for 
the Iron and Steel Foundries source categories?

    For each issue, this section provides a description of what we 
proposed and what we are finalizing for the issue, the EPA's rationale 
for the final decisions and amendments, and a summary of key comments 
and responses. 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 titled National Emission Standards for Hazardous 
Air Pollutants: Iron and Steel Foundries Major Source Residual Risk and 
Technology Review and Area Source Technology Review--Final Rule--
Summary of Public Comments and Responses, which is available in the 
docket (Docket ID No. EPA-HQ-OAR-2019-0373).

A. Residual Risk Review for the Major Source Iron and Steel Foundries 
Source Category

1. What did we propose pursuant to CAA section 112(f) for the major 
source Iron and Steel Foundries source category?
    We proposed that the health risks due to emissions of HAP from the 
major source Iron and Steel Foundries source category are acceptable 
and that the NESHAP provides an ample margin of safety to protect 
public health and that no additional standards are necessary to prevent 
an adverse environmental effect.
    Table 2 of this preamble provides a summary of the results of the 
inhalation risk assessment for the source category. More detailed 
information on the risk assessment can be found in the Residual Risk 
Assessment for the Iron and Steel Foundries Major Source Category in

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
\1\ Number of facilities evaluated in the risk analysis.
\2\ Maximum individual excess lifetime cancer risk due to HAP emissions from the source category.
\3\ Maximum target organ-specific hazard index (TOSHI). The target organ system with the highest TOSHI for the source category is respiratory. The respiratory TOSHI was calculated using the
  California EPA (CalEPA) chronic reference exposure level (REL) for acrolein.
\4\ The maximum estimated acute exposure concentration was divided by available short-term dose-response values to develop an array of hazard quotient (HQ) values. HQ values shown use the
  lowest available acute dose-response value, which in most cases is the REL. When an HQ exceeds 1, we also show the HQ using the next lowest available acute dose-response value.

    As shown in Table 2, for the major source Iron and Steel Foundries 
source category, the maximum cancer risk to the individual most exposed 
is 50-in-1 million due to actual emissions or allowable emissions. This 
risk is less than 100-in-1 million, which is the presumptive upper 
limit of acceptable risk. The estimated incidence of cancer due to 
inhalation exposures for the source category is 0.02 excess cancer 
cases per year, or one excess case every 50 years. We estimated that 
approximately 144,000 people face an increased cancer risk greater than 
or equal to 1-in-1 million due to inhalation exposure to HAP emissions 
from this source category. The Agency estimated that the maximum 
chronic noncancer TOSHI from inhalation exposure, 0.5 (spleen), is less 
than 1. The screening assessment of worst-case acute inhalation impacts 
estimated a maximum acute HQ of 1 (due to arsenic) based on the REL.
    With regard to multipathway human health risks, we estimated the 
maximum cancer risk for the highest exposed individual is 20-in-1 
million (due to polycyclic organic matter (POM)) and the maximum 
noncancer chronic HQs are less than 1 for all the HAP known to be 
persistent and bio-accumulative in the environment (PB-HAP).
    A screening-level evaluation of the potential adverse environmental 
risk associated with emissions of arsenic, cadmium, dioxins, hydrogen 
chloride, hydrogen flouride, lead, mercury, and POM indicated that no 
ecological benchmarks were exceeded. Considering all the health risk 
information and factors discussed above, the EPA proposed that the 
risks are acceptable and that no additional standards are necessary to 
prevent an adverse environmental effect.
    Under the ample margin of safety analysis, we evaluated the cost 
and feasibility of available control technologies and other measures 
that could be applied to further reduce the risks (or potential risks) 
due to emissions of HAP from the source category. The main control we 
evaluated to reduce organic HAP emissions was carbon adsorption as a 
possible add-on control to further reduce VOHAP and associated risks 
from mold- and core-making and pouring, cooling and shakeout lines at 
existing sources. The main control we evaluated to reduce metal HAP 
emissions was improved capture of fugitive PM emissions from scrap 
handling and melting furnaces and routing them to fabric filter control 
devices.
    We estimated the cost of the additional controls to reduce organic 
HAP emissions would be $12,700 per ton of organic HAP reduced or 
greater and would require a capital investment exceeding $27 million. 
With regard to risk reductions, we estimated the maximum individual 
risk (MIR) would be reduced from 50-in-1 million to 30-in-1 million, 
and the number of people with risks >= 1-in-1 million would also be 
reduced.
    We estimated the cost of the improved capture and control to reduce 
metal HAP emissions would be almost $800,000 per ton metal HAP reduced 
and would require a capital investment of $23 million. With regard to 
risk reductions, we estimated the HAP metals contribution to the MIR 
would be reduced from 30-in-1 million to 3-in-1 million, and the number 
of people with risks >= 1-in-1 million would also be reduced.
    Based on consideration of the costs and cost effectiveness of both 
the organic HAP and metal HAP emission control systems, consideration 
of potential impacts to small businesses, the moderate risk reductions 
that would be achieved, and the uncertainties in the emissions 
estimates, we proposed that the Iron and Steel Foundries major source 
NESHAP provides an ample margin of safety to protect public health, and 
we did not propose any changes to the NESHAP based on the risk review. 
For more details regarding the risk review, including the ample margin 
of safety analysis, see the proposal preamble (84 FR 54398).
2. How did the risk review change for the major source Iron and Steel 
Foundries source category?
    The EPA has not made any changes to either the risk assessments or 
our determinations regarding risk acceptability, ample margin of 
safety, or adverse environmental effects for the major source Iron and 
Steel Foundries source category since the proposal was published on 
October 9, 2019. We are finalizing the risk review as proposed with no 
changes (84 FR 54394, October 9, 2019).
3. What key comments did we receive on the risk review, and what are 
our responses?
    Comment: Several commenters agreed with the EPA's conclusion that 
risks from iron and steel foundry emissions are acceptable and that the 
current standards provide an ample margin of safety, but they suggested 
that the emissions data used by the EPA are outdated and flawed and 
that actual emissions are lower, which would result in even lower risk 
projections. They also stated that the costs of additional controls 
were significantly understated. According to the commenters, the higher 
cost coupled with lower emissions, which would also lower the estimated 
emission reductions, demonstrates that additional controls are not cost 
effective. On the other hand, one commenter opposed the risk 
conclusions stating that the EPA did not fully consider fugitive 
emissions.
    Response: Regarding comments on the accuracy and completeness of 
the emissions and cost estimates, we used the best available emissions 
data in our risk assessment. We consider the emissions and release 
characteristics

[[Page 56086]]

used in the risk assessment to be reasonable and appropriate for the 
analysis conducted. It is clear that fugitive emission sources were 
included as several of these sources were driving the risk estimates 
for most facilities. We intentionally conducted a screening assessment 
of control measures using best-case (lowest cost) assumptions to 
determine whether, under ideal conditions, these controls might be cost 
effective. Based on the results of our screening analysis, we concluded 
that the controls were not warranted based on costs and that more 
detailed analyses of these control systems were not necessary (for more 
details see the preamble of the proposed rule, 84 FR 54412, October 9, 
2019).
    Comment: One commenter opposed the risk acceptability conclusion 
stating that the EPA significantly underestimated the risk because the 
EPA's Residual Risk Assessment failed to follow the best available 
science, including:
    (1) Underestimating health threats to children and from early-life 
exposure by ignoring increased risk in childhood and from prenatal 
exposure;
    (2) underestimating health threats to communities exposed to 
multiple sources by refusing to add factors to account for the 
increased risks caused by such exposure;
    (3) underestimating health threats by refusing to assess health 
risks at all for pollutants such as lead and refusing to assess 
multipathway risks for additional emitted persistent bioaccumulative 
pollutants such as toxic metals like chromium (VI), nickel, beryllium, 
antimony, and manganese; and
    (4) underestimating the cancer, chronic noncancer, and acute health 
risks by using modeling assumptions that ignore real-world exposures, 
underestimating risk from chemicals such as benzene, 1,3-butadiene, 
nickel, manganese, and lead due to the EPA's refusal to follow the best 
available science and ignoring the more protective health values 
created by CalEPA's Office of Environmental Health Hazard Assessment 
(OEHHA).
    Response: The EPA disagrees with the commenter's claim that the 
risk assessment for this source category does not consider the groups 
that may be most at risk (e.g., children and developing fetuses). When 
the EPA derives dose-response values for HAP, it considers the most 
sensitive populations identified in the available literature, and these 
are the values used in the Agency's risk assessments.\5\ The EPA has an 
approach for selecting appropriate health benchmark values and, in 
general, this approach places greater weight on the EPA-derived health 
benchmarks than those from other agencies for the reasons explained in 
the document titled Residual Risk Assessment for the Iron and Steel 
Foundries Major Source Category in Support of the 2020 Risk and 
Technology Review Final Rule, available in the docket (Docket ID No. 
EPA-HQ-OAR-2019-0373). Additionally, the approach of favoring the EPA 
benchmarks (when they exist) has been endorsed by the Science Advisory 
Board (SAB) and ensures the use of values most consistent with well-
established and scientifically-based EPA science policy. The EPA 
continually evaluates other benchmarks, including CalEPA OEHHA child-
specific reference doses (RfDs) and more recent inhalation RELs \6\ in 
the context of assessing risk from exposure to HAP.

    \6\ More recently published OEHHA RELs use a more protective set 
of inter-individual uncertainty factors (UFs), with a default of 30 
as opposed to the EPA default of 10 with the intent of protecting 
for more susceptible individuals, most notably children.
---------------------------------------------------------------------------

    With respect to cancer, the EPA uses an age-dependent adjustment 
factor approach referred to by the commenter but limits the application 
of age-dependent adjustment factors to carcinogenic pollutants that are 
known to act via mutagenic mode of action (MOA); in contrast, the 
CalEPA OEHHA approach is to apply adjustment factors across the board 
for all carcinogens, regardless of MOA. In lieu of chemical-specific 
data on which age or life-stage specific risk estimates or potencies 
can be determined, default age-dependent adjustment factors can be 
applied when assessing cancer risk for early-life exposures to 
chemicals that cause cancer through a mutagenic MOA. With regard to 
other carcinogenic pollutants (e.g., non-mutagenic) for which early-
life susceptibility data are lacking, it is the Agency's long-standing 
science policy position that use of the linear low-dose extrapolation 
approach (without further adjustment) provides adequate public health 
conservatism in the absence of chemical-specific data indicating 
differential early-life susceptibility or when the MOA is not 
mutagenicity.\7\ The basis for this methodology is provided in the 
EPA's 2005 Supplemental Guidance for Assessing Susceptibility from 
Early-Life Exposure to Carcinogens.\8\

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

    The EPA also disagrees with the commenter that a children's default 
safety factor of 10 or more should be added to the EPA's reference 
values in response to the 10X factor enacted by Congress in the Food 
Quality Protection Act (FQPA) in 1996.9 10 In response to 
the EPA noncancer reference value derivation, the Agency evaluated the 
methods for considering children's risk in the development of reference 
values. As part of the response, the EPA (i.e., the Science Policy 
Council and Risk Assessment Forum) established the RfD/reference 
concentration (RfC) Technical Panel to develop a strategy for 
implementing the FQPA and examine the issues relative to protecting 
children's health and application of the 10X safety factor. One of the 
outcomes of the Technical Panel's efforts was an in-depth review of a 
number of issues related to the RfD/RfC process.\11\ The most critical 
aspect in the derivation of a reference value pertaining to the FQPA 
has to do with variation between individual humans and is accounted for 
by a default UF when no chemical-specific data are available. The EPA 
reviewed the default UF for inter-human variability and found the EPA's 
default value of 10 adequate for all susceptible populations, including 
children and infants. The EPA also recommended the use of chemical-
specific data in preference to default UFs when available \12\ and has 
developed Agency guidance to facilitate consistency in the development 
and use of data-derived extrapolation factors for RfCs and RfDs.\13\ 
Additionally, the EPA also

[[Page 56087]]

applies a database UF, which is intended to account for the potential 
for deriving an under protective RfD/RfC as a result of an incomplete 
characterization of the chemical's toxicity. In addition to the 
identification of toxicity information that is lacking, review of 
existing data may also suggest that a lower reference value might 
result if additional data were available.

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

    In conclusion, the estimated risks must also be considered in the 
context of the full set of assumptions used for this risk assessment. 
The EPA's dose-response values for HAP are considered plausible upper-
bound estimates with an appropriate age-dependent adjustment factor. 
The EPA's chronic noncancer reference values have been derived 
considering the potential susceptibility of different subgroups, with 
specific consideration of children. An extra 10-fold UF is not needed 
in the RfC/RfD methodology because the currently applied factors are 
considered sufficient to account for uncertainties in the database from 
which the reference values are derived.
    Regarding the commenter's assertion that the EPA has underestimated 
health threats to communities exposed to multiple sources, the EPA 
typically examines facility-wide risks to provide additional context to 
the source category risks. The development of facility-wide risk 
estimates provides additional information about the potential 
cumulative risks in the vicinity of the RTR sources, as one means of 
informing potential risk-based decisions about the RTR source category 
in question. Because these risk estimates were derived from facility-
wide emissions estimates that have not generally been subjected to the 
same level of engineering review as the source category emission 
estimates, they may be less certain than the 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.
    The EPA notes that section 112(f)(2) of the CAA expressly preserves 
the EPA's use of the two-step process for developing standards to 
address residual risk and interpret ``acceptable risk'' and ``ample 
margin of safety'' as developed in the Benzene NESHAP. In the Benzene 
NESHAP, the EPA rejected approaches that would have mandated 
consideration of background levels of pollution in assessing the 
acceptability of risk, concluding that ``With respect to considering 
other sources of risk from benzene exposure and determining the 
acceptable risk level for all exposures to benzene, the EPA considered 
this inappropriate because only the risk associated with the emissions 
under consideration are relevant to the regulation being established 
and, consequently, the decisions being made.'' (54 FR 38044, September 
14, 1989). The EPA's authority to use the two-step process laid out in 
the Benzene NESHAP, and to consider a variety of measures of risk to 
public health, is discussed more thoroughly in the preamble to the 
proposed rule. Nothing in the CAA or the Benzene NESHAP in any way 
forecloses the EPA from considering facility-wide risks in making a 
determination under CAA section 112(f)(2), as such information can 
constitute relevant health information. Although not considered in the 
determination of acceptable risk, the EPA notes that background risks 
or contributions to risk from sources outside the source category under 
review could be one of the relevant factors considered in the ample 
margin of safety determination, along with cost and economic factors, 
technological feasibility, and other factors.
    The EPA acknowledges it does not have screening values for some of 
the PB-HAP but the EPA disagrees that the multipathway assessment is 
inadequate. In the Air Toxics Assessment Library (available at: https://www.epa.gov/fera/risk-assessment-and-modeling-air-toxics-risk-assessment-reference-library), the EPA developed the current PB-HAP 
list considering all of the available information on persistence and 
bioaccumulation. This list reviewed HAP identified as PB-HAP by other 
EPA program offices (e.g., the Great Waters Program). This list was 
peer-reviewed by the SAB and found to be acceptable and, therefore, the 
EPA considers it to be reasonable for use in the RTR program. Based on 
these sources and the limited available information on the persistence 
and bioaccumulation of other HAP, the EPA does not think that the 
potential for multipathway risk from other HAP rises to the level of 
the PB-HAP currently on the list.
    The EPA disagrees that it has failed to assess potential risks from 
lead. As for other pollutants included in the assessment of noncancer 
hazard from inhalation, RTR assessments include lead in the calculation 
of TOSHIs. For lead, neurological and developmental TOSHIs are 
calculated. In these indices, modeled concentrations of lead are 
compared to the 2008 lead National Ambient Air Quality Standards 
(NAAQS) (which was reviewed and retained in 2016),\14\ and other 
pollutant concentrations are compared to their respective noncancer 
reference values, then the individual pollutant HQs are summed to 
calculate the TOSHIs. To assess the potential for hazard from 
multipathway exposures, modeled air concentrations are compared to the 
lead NAAQS. The EPA notes that in developing the NAAQS for lead, air-
related multipathway effects were already taken into account. That is, 
as noted at 73 FR 66971, ``As was true in the setting of the current 
standard, multimedia distribution of and multipathway exposure to Pb 
that has been emitted into the ambient air play a key role in the 
Agency's consideration of the Pb NAAQS.''
---------------------------------------------------------------------------

    \14\ https://www.epa.gov/lead-air-pollution/national-ambient-air-quality-standards-naaqs-lead-pb.
---------------------------------------------------------------------------

    While recognizing that lead has been demonstrated to exert ``a 
broad array of deleterious effects on multiple organ systems,'' the 
lead NAAQS targets the effects associated with relatively lower 
exposures and associated blood lead levels, specifically nervous system 
effects in children including cognitive and neurobehavioral effects (73 
FR 66976). The 2008 decision on the lead NAAQS was informed by an 
evidence-based framework for neurocognitive effects in young children. 
In applying the evidence-based framework, the EPA focused on a 
subpopulation of U.S. children, those living near air sources and more 
likely to be exposed at the level of the standard; to the same effect 
see 73 FR 67000/3--``The framework in effect focuses on the sensitive 
subpopulation that is the group of children living near sources and 
more likely to be exposed at the level of the standard. The evidence-
based framework estimates a mean air-related IQ loss for this 
subpopulation of children; it does not estimate a mean for all U.S. 
children''; 73 FR 67005/1--``the air-related IQ loss framework provides 
estimates for the mean air-related IQ loss of a subset of the 
population of U.S. children, and there are uncertainties associated 
with those estimates. It provides estimates for that subset of children 
likely to be exposed to the level of the standard, which is generally 
expected to be the subpopulation of children living near sources who 
are likely to be most highly exposed.'' In addition, in reviewing and 
sustaining the lead primary NAAQS, the EPA notes that the Court 
specifically noted that the rule was targeted to protect children 
living near lead sources: ``EPA explained that the scientific evidence

[[Page 56088]]

showing the impact of lead exposure in young children in the United 
States led it `to give greater prominence to children as the sensitive 
subpopulation in this review' and to focus its revision of the lead 
NAAQS on the `sensitive subpopulation that is the group of children 
living near [lead emission] sources and more likely to be exposed at 
the level of the standard.' Given the scientific evidence on which it 
relied, the EPA's decision to base the revised lead NAAQS on protecting 
the subset of children likely to be exposed to airborne lead at the 
level of the standard was not arbitrary or capricious.'' Coalition of 
Battery Recyclers, 604 F. 3d at 618.
    Regarding the comment that the EPA underestimates the cancer, 
chronic noncancer, and acute health risks by using modeling assumptions 
that ignore real-world exposures, underestimating risk from other 
chemicals such as benzene, 1,3-butadiene, nickel and manganese, due to 
the EPA's refusal to follow the best available science and ignoring the 
more protective health values created by CalEPA's OEHHA, the EPA uses 
dose-response information that has been obtained from various sources. 
As noted above, the dose-response information is prioritized according 
to (1) conceptual consistency with the EPA's risk assessment guidelines 
and (2) level of public and peer review received. The prioritization 
process is aimed at incorporating into RTR assessments the best 
available science with respect to dose-response information. 
Application of this approach generally results in the following 
priority order: (1) U.S. EPA IRIS, (2) Agency for Toxic Substances and 
Disease Registry (ATSDR), (3) CalEPA, and (4) other sources. Deviations 
from this prioritization only occur if there are concerns that the top 
priority values have become outdated or newer evidence suggests they 
are not protective; such was not the case for the values used in this 
RTR assessment. Based on this approach, the EPA determined that the 
best available science was used in the risk assessment, that the risks 
are acceptable, that the existing standards provide an ample margin of 
safety to protect public health, and that no changes are needed from 
the proposal based on this comment.
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 MIR of approximately 1-in-10 thousand'' 
(see 54 FR 38045, September 14, 1989). We weigh all health risk factors 
in our risk acceptability determination, including the cancer MIR, 
cancer incidence, the maximum chronic noncancer 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.
    In the second step of the approach, the EPA considers whether the 
emissions standards provide an ample margin of safety to protect public 
health ``in consideration of all health information, including the 
number of persons at risk levels higher than approximately 1-in-1 
million, as well as other relevant factors, including costs and 
economic impacts, technological feasibility, and other factors relevant 
to each particular decision.'' Id. We evaluated additional control 
measures to reduce the number of persons exposed at risk levels higher 
than approximately 1-in-1 million and determined that these additional 
control measures were not reasonable considering the costs and economic 
impacts. Therefore, we concluded that the major source Iron and Steel 
Foundries NESHAP provides an ample margin of safety to protect public 
health without any revisions. After conducting the ample margin of 
safety analysis, we consider whether a more stringent standard is 
necessary to prevent, taking into consideration costs, energy, safety, 
and other relevant factors, an adverse environmental effect.
    We 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, we determined that the risks from the major source Iron 
and Steel Foundries source category are acceptable, the current 
standards provide an ample margin of safety to protect public health, 
and more stringent standards are not necessary to prevent an adverse 
environmental effect. Therefore, pursuant to CAA section 112(f)(2), we 
are finalizing our residual risk review as proposed and readopting the 
standards for the major source Iron and Steel Foundries source 
category.

B. Technology Review for the Iron and Steel Foundries Source Categories

1. What did we propose pursuant to CAA section 112(d)(6) for the Iron 
and Steel Foundries source categories?
    Pursuant to CAA section 112(d)(6), we proposed to conclude that no 
revisions to the current major source or area source NESHAP for Iron 
and Steel Foundries are necessary. Based on our technology review 
described in the October 9, 2019, proposal (84 FR 54414), we determined 
that there are no developments in practices, processes, or control 
technologies that necessitate revisions to the NESHAP for major source 
Iron and Steel Foundries (40 CFR part 63, subpart EEEEE) or the NESHAP 
for area source Iron and Steel Foundries (40 CFR part 63, subpart 
ZZZZZ).
2. How did the technology review change for the Iron and Steel 
Foundries source categories?
    The EPA has not made any changes to the technology review since the 
proposal was published on October 9, 2019. We are finalizing the 
technology review as proposed with no changes.
3. What key comments did we receive on the technology reviews, and what 
are our responses?
    Comment: Several commenters agreed with the EPA's proposed 
technology review conclusions. Other commenters suggested that the EPA 
needed to revise the standards because the EPA specifically considered 
the National Vehicle Mercury Switch Recovery Program (NVMSRP) to be a 
``development'' with respect to the major source MACT standards. These 
commenters also suggested that the EPA should consider fugitive control 
measures required by Bay Area Air Quality Management District 
(``BAAQMD'') and South Coast Air Quality Management District 
(``SCAQMD'') standards and work practices considered in the EPA's 
proposed Integrated Iron and Steel Manufacturing RTR proposed rule (84 
FR 42704, August 16, 2019) to be ``developments'' for major and area 
source foundries and take these into account in this rulemaking.
    Response: As an initial matter, CAA section 112(d)(6) does not 
require the EPA to revise the standards if a ``development'' is 
identified, but to consider whether it is necessary to revise the 
standards in light of the developments. While we acknowledge that the 
NVMSRP was initiated after the major source rule (40 CFR part 63, 
subpart EEEEE) was promulgated, we note that the major source rule 
includes

[[Page 56089]]

requirements to remove mercury switches from automotive scrap 
consistent with the NVMSRP and that it acted as a catalyst for the 
development of the NVMSRP. Because the major source rule already 
requires mercury switch removal consistent with this ``development,'' 
no additional revisions to the major source rule were deemed 
``necessary.'' With respect to additional fugitive emissions 
requirements, we specifically assessed adding improved capture and 
control requirements to reduce emissions of fugitive metal HAP 
emissions similar to those suggested by the commenter (see Control Cost 
Estimates for Metal HAP Emissions from Iron and Steel Foundries, which 
is available in the docket as Docket Item No. EPA-HQ-OAR-2019-0373-
0015). We concluded that these control measures were not cost effective 
and that it was not necessary to revise the rule to reduce fugitive 
metal HAP emissions. Thus, we maintain our conclusion that it is not 
necessary to revise the standards based on the developments cited by 
the commenter.
4. What is the rationale for our final approach for the technology 
reviews?
    We evaluated all of the comments on the technology reviews and 
determined that no changes to the reviews are needed. Therefore, 
pursuant to CAA section 112(d)(6), we are finalizing our technology 
reviews as proposed.

C. Removal of the SSM Exemptions

1. What did we propose?
    The EPA proposed amendments to the major and area source Iron and 
Steel Foundries NESHAP to remove the provisions related to SSM in order 
to ensure that they are consistent with the Court decision in Sierra 
Club v. EPA, 551 F. 3d 1019 (D.C. Cir. 2008) that standards apply at 
all times. As detailed in the October 2019 proposal, we proposed the 
following amendments.
     Revising the General Provisions applicability tables 
(Table 1 to subpart EEEEE of part 63 and Table 3 to subpart ZZZZZ of 
part 63) to change the following entries from a ``yes'' in column 3 
(indicating the provision applies) to a ``no'':

[cir] 40 CFR 63.6(e)
[cir] 40 CFR 63.6(f)(1)
[cir] 40 CFR 63.6(h)(1)
[cir] 40 CFR 63.7(e)(1)
[cir] 40 CFR 63.8(c)(1)(i) and (iii)
[cir] 40 CFR 63.8(d)(3)
[cir] 40 CFR 63.10(b)(2)(i), (ii), (iv), and (v)
[cir] 40 CFR 63.10(c)(7) [for subpart EEEEE]; 40 CFR 63.10(c) [for 
subpart ZZZZZ]
[cir] 40 CFR 63.10(d)(5)
[cir] 40 CFR 63.10(e)(3) [for subpart ZZZZZ; subpart EEEEE already 
indicates ``no'']

     Revising the following paragraphs in 40 CFR part 63, 
subpart EEEEE, to remove the language in the rule that exempted 
affected sources from compliance with the standards during periods of 
SSM, as well as references to General Provision sections or 
requirements that no longer apply.

[cir] 40 CFR 63.7710(a) to remove reference to 40 CFR 63.6(e)(1)(i)
[cir] 40 CFR 63.7720(a) to delete the phrase ``. . ., except during 
periods of startup, shutdown, or malfunction''
[cir] 40 CFR 63.7720(c) to delete and reserve the paragraph
[cir] 40 CFR 63.7746(b) to delete and reserve the paragraph
[cir] 40 CFR 63.7751(b)(4) and (c) to delete and reserve the paragraphs
[cir] 40 CFR 63.7752(a)(2) to remove reference to 40 CFR 63.6(e)(3) and 
require records require by 40 CFR 63.10(b)(2)(iii)
[cir] 40 CFR 63.7752(b)(4) to remove the records needed to indicate 
whether deviation of a continuous emission monitoring system occurred 
during periods of SSM

     Revising the following paragraphs in 40 CFR part 63, 
subpart ZZZZZ, to remove references to General Provision sections or 
requirements that no longer apply.

[cir] 40 CFR 63.10890(i) [re-designated to 40 CFR 63.10890(j)] to 
remove reference to 40 CFR 63.6(e)
[cir] 40 CFR 63.10897(g) to remove reference to minimizing periods of 
SSM
[cir] 40 CFR 63.10899(b) to revise the general reference to records 
required by 40 CFR 63.10 to specify that only records required by 40 
CFR 63.10(b)(2)(iii), (vi) through (xiv), and (b)(3) are necessary

     Adding 40 CFR 63.7752(d) of subpart EEEEE and 40 CFR 
63.10899(b)(15) of subpart ZZZZZ to specify recordkeeping requirements 
during a malfunction.
     Revising 40 CFR 63.7751(b)(7) and (8) of subpart EEEEE and 
40 CFR 63.10899(c) of subpart ZZZZZ to specify reporting requirements 
for specific deviations.
    We proposed that the effective date of these revisions be the date 
of promulgation of the final rule. More information concerning the 
elimination of SSM provisions is in the preamble to the proposed rule 
(84 FR 54415-44419, October 9, 2019).
2. What changed since proposal?
    For the area source rule (40 CFR part 63, subpart ZZZZZ), we are 
finalizing the revisions to the SSM provisions as proposed with no 
changes. For the major source rule (40 CFR part 63, subpart EEEEE), we 
are finalizing most revisions regarding SSM provisions as proposed such 
that the emission limits apply at all times without the need for 
different standards during periods of startup and shutdown. However, 
for new and existing major source cupola melting furnaces, we are 
finalizing specific work practice standards for VOHAP emissions that 
apply during startup and shutdown. For cupola melting furnaces, we are 
finalizing that the 20 ppmv VOHAP emission limit in 40 CFR 
63.7690(a)(8) applies only while the cupola is ``on blast'' (normal 
operations) and we are adding work practice standards at 40 CFR 
63.7700(g) to limit VOHAP emissions during periods of off blast, which 
includes startup, shutdown, or idling. We are adding reference to these 
new work practice standards in 40 CFR 63.7710(b) so that the O&M plan 
specifically covers the capture and control systems used to comply with 
the new work practice standards. We are adding reference to these new 
work practice standards at 40 CFR 63.7740(e) and 63.7741(d) to require 
temperature monitoring to demonstrate that the afterburner or other 
thermal combustion device flame is present as required in 40 CFR 
63.7700(g)(2)(i). We are also adding additional recordkeeping 
requirements at 40 CFR 63.7744(e) for facilities to demonstrate 
continuous compliance with the new work practice standards. These 
records include: Combustion zone temperature for the cupola's thermal 
combustion control device, the time blast air is started to begin the 
coke bed burn-in, the time the cupola afterburner or other thermal 
combustion device is lit, the time metal production starts during 
cupola startup, the time when metal production ends, the time slag 
removal was completed, the time the afterburner or other thermal 
combustion device is turned off during cupola shutdown, and the times 
idling starts and stops.
    With regard to compliance dates, we are providing 180 days to 
comply with these new work practice standards for major source iron and 
steel foundries and also for the SSM related provisions in 40 CFR 
63.7720 including provisions that state the emission limits apply at 
all times. We are retaining the rule-specific SSM provisions from the 
original NESHAP (including the requirement to have an SSM plan) for the 
first 180 days until the compliance date for the new work practice 
standards becomes effective. For other proposed SSM

[[Page 56090]]

revisions in the major source rule and for all of the proposed SSM 
revisions in that area source rule, which are predominately revisions 
to General Provisions applicability tables, we are finalizing 
requirements that foundry owners or operators will need to comply with 
these revisions on the date this final rule is published in the Federal 
Register.
3. What are the key comments and what are our responses?
    Comments: Several commenters supported the proposed removal of the 
SSM exemptions. One commenter indicated that meeting the parametric 
monitoring requirement of 1,300 degrees Fahrenheit for afterburners 
that are used to control VOHAP emissions from cupola furnaces is likely 
to be an issue during cupola startup and shutdown and recommended new 
definitions of ``cupola startup'' and ``cupola shutdown,'' and 
revisions to the definition of ``off blast'' as follows:
    Cupola Startup means the time beginning when molten metal is first 
tapped from a cupola that had previously been shut down.
    Cupola Shutdown means the time ending once the last charge is added 
to the cupola preceding either cupola banking or cupola bottom drop.
    Off Blast means those periods of cupola operation when the cupola 
is not actively being used to produce molten metal. Off blast 
conditions also include idling conditions when the blast air is turned 
off or down to the point that the cupola does not produce additional 
molten metal.
    The same commenter recommended that the compliance date related to 
SSM-related rule changes be revised to 180 days after the date of the 
final rule for both subparts EEEEE and ZZZZZ of 40 CFR part 63 to allow 
facilities sufficient time to extract O&M plans that may be integrated 
with SSM plans as well as to develop other facility-specific procedures 
to address amended rule requirements related to SSM events.
    Response: As discussed in the preamble to the October 2019 proposal 
(84 FR 54415, October 9, 2019), we acknowledged that the cupola 
afterburners would not be able to meet the 1,300 degrees Fahrenheit 
parametric monitoring temperature limit during off blast conditions, 
but we expected that the emissions would still be compliant with the 20 
ppmv VOHAP emission limit. Therefore, initially, we did not understand 
why the new definitions would be helpful or necessary. So, we contacted 
the commenter to seek clarification of their comments. On February 12, 
2020, we had a teleconference meeting with the commenter to try to 
better understand the issue. The notes of the meeting are in the docket 
for this rulemaking (Docket ID No. EPA-HQ-OAR-2019-0373). On March 9, 
2020, the commenter provided a document providing further detail of the 
cupola startup and shutdown procedures and suggested work practices as 
an alternative to the suggested definitions (see email from Jeff 
Hannapel to Phil Mulrine dated March 9, 2020, included in Docket ID No. 
EPA-HQ-OAR-2019-0373). On April 2, 2020, we had an additional 
teleconference meeting with the commenter to discuss the information 
provided in the March 9, 2020, email. The notes of this meeting are 
also in the docket for this rulemaking (Docket ID No. EPA-HQ-OAR-2019-
0373).
    During the meetings, the commenter clarified that their main 
concern was the VOHAP emissions limit, not the temperature limit. They 
explained that there is uncertainty as to whether the cupola furnaces 
would meet the VOHAP limit during these periods and that no one has 
ever tested emissions during these periods. We also learned that the 
definitions suggested by the commenter were intended to remove 
preparatory steps from what was considered startup because of the 
uncertainty regarding whether they would be able to meet the VOHAP 
emissions limit during those periods. However, as some of these 
preparatory steps have the potential to emit VOHAP, we concluded that 
the suggested definitions were not consistent with the 2008 Court 
decision in Sierra Club v. EPA, 551 F. 3d 1019 (D.C. Cir. 2008).
    Based on our improved understanding of the startup and shutdown 
procedures for the cupola furnace and related issues, we have 
determined that work practice standards are appropriate for these 
periods. As noted in CAA section 112(h)(1), ``if it is not feasible in 
the judgment of the Administrator to prescribe or enforce an emission 
standard for control of a hazardous air pollutant or pollutants, the 
Administrator may, in lieu thereof, promulgate a design, equipment, 
work practice, or operational standard, or combination thereof, which 
in the Administrator's judgment is consistent with the provisions of 
subsection (d) or (f).'' CAA section 112(h)(2) defines the phrase ``not 
feasible to prescribe or enforce an emission standard'' as any 
situation in which the Administrator determines that either ``a 
hazardous air pollutant or pollutants cannot be emitted through a 
conveyance designed and constructed to emit or capture such pollutant, 
or that any requirement for, or use of, such a conveyance would be 
inconsistent with any Federal, State or local law'' or ``the 
application of measurement methodology to a particular class of sources 
is not practicable due to technological and economic limitations.''
    We have concluded that, during periods of cupola off blast, which 
includes startup, shutdown, and idling, it is not feasible to prescribe 
or enforce the numeric limits of the emission standard for VOHAP and 
that standards may be appropriately established under CAA section 
112(h). The cupola furnace is essentially an open column during the 
initial cupola startup steps and during the final cupola shutdown 
steps, and the emissions are not emitted through a conveyance. Further, 
the initial procedures to prepare the cupola bed or remove the cupola 
from service cannot be safely completed with the cupola VOHAP control 
system operating. After further evaluation, we have determined the 
appropriate requirements for these steps (specifically refractory 
curing, cupola bed preparation, and the initial phases of cupola coke 
bed preparation during cupola startup and the final cooling stages and 
cupola banking or bottom drop during cupola shutdown) are the general 
duty requirements in 40 CFR 63.7710(a) to operate according to 
procedures to minimize emissions as contained in the O&M plan and to 
comply with the opacity limit at 40 CFR 63.7690(a)(7). We are adding 
definitions of ``cupola startup'' and ``cupola shutdown'' to describe 
the various steps for cupola startup and cupola shutdown to clarify 
when the work practice standards apply. For other startup and shutdown 
procedures, the cupola tuyere covers are closed, and the capture and 
control system can be operated. We modified the definition of ``off 
blast'' to clearly specify that off blast includes shutdown procedures 
as well as startup procedures. Even though the capture system can be 
operated during portions of off blast periods, we determined that the 
application of reliable emissions measurement methodologies to this 
source during these off blast periods is not practicable due to 
technological limitations. First, the flow rates during periods of off 
blast are typically low and highly variable. Additionally, the off 
blast periods are short duration (e.g., less than 3 hours), and the 
required duration of a performance test to evaluate compliance with the 
VOHAP emission limit is 3 hours. As such, we determined that work 
practice standards

[[Page 56091]]

are appropriate for VOHAP during off blast periods. We are requiring 
that owners/operators (1) begin operating the cupola afterburner or 
other thermal combustion device as soon as practicable after beginning 
the coke bed preparatory step but no later than 30 minutes after the 
blast air is started to begin the coke bed burn-in and (2) operate the 
afterburner or other thermal combustion device with a flame present at 
all times during other off blast periods. Maintaining the operation of 
the afterburner during off blast periods will ensure VOHAP emissions 
that come from the process are combusted. Based on our understanding of 
the current operations of these furnaces and practices applied in the 
industry, we believe these requirements reflect the procedures of the 
best performing sources.
    With respect to the compliance dates related to SSM changes, we 
proposed that the proposed revisions would become effective immediately 
because we expected that facilities could comply immediately with the 
standards at all times and that no or limited revisions in procedures 
would be needed. Because we are finalizing specific work-practice 
standards that apply to VOHAP emissions during cupola startup and 
shutdown for major source iron and steel foundries, we expect that some 
facilities will need to revise their startup procedures and revise 
their O&M plans to comply with the new work practice standards. 
Consequently, as suggested by the commenter, we are providing 180 days 
for major source facilities to transition from their existing SSM plans 
to compliance with the emission limitations, including the new work 
practice standards, at all times. We consider 180 days to be the 
minimum time needed to complete the management of these changes, which 
includes evaluating the changes, forming a team to accomplish the 
changes, conducting safety assessments, updating associated plans and 
procedures, and providing training to implement the changes. We 
consider a period of 180 days to be the most expeditious compliance 
period practicable, and, thus, we are finalizing the requirement that 
existing affected sources be in compliance with all of the revised 
requirements in the major source NESHAP within 180 days of the 
effective date of this final rule. We are revising 40 CFR 63.7720(a) 
and (c), which require preparation and operation according to an SSM 
plan, to provide a 180-day compliance period with these specific SSM 
provisions in the major source NESHAP as foundry owners or operators 
transition to the new work practice standards for cupola VOHAP 
emissions. Additional time is not required for the areas source NESHAP 
SSM revisions that were proposed or other major source NESHAP SSM 
revisions (not referenced above) that were proposed because operational 
changes are not needed to implement these other revisions, which are 
primarily revisions to the General Provisions applicability tables. As 
such, we are finalizing that those requirements become effective upon 
the date of promulgation as proposed.
4. What is the rationale for our final approach for the SSM provisions?
    We evaluated all comments on the EPA's proposed amendments to 
remove the SSM provisions. For the reasons explained in the proposed 
rule, we determined that the proposed removal of the SSM exemptions is 
required to be consistent with the 2008 Court decision that standards 
apply at all times. For the area source NESHAP, we are finalizing our 
approach for removing the SSM exemptions as proposed. For the major 
source NESHAP, we are finalizing our approach for removing the SSM 
exemptions as proposed, except for provisions related to cupola furnace 
VOHAP emission limits. More information concerning the non-cupola 
amendments that we are finalizing for SSM is in the preamble to the 
proposed rule (84 FR 54415-54419, October 9, 2019). For cupola furnaces 
at major source iron and steel foundries, as described above in section 
IV.C.3 of this preamble, we determined that work practice standards 
during startup and shutdown are appropriate for the VOHAP standards 
under the provision of CAA section 112(h). We added monitoring and 
recordkeeping requirements for foundry owners or operators to 
demonstrate compliance with the new work practice standards. The 
temperature monitoring requirement is the same as needed to demonstrate 
compliance during normal ``on blast'' conditions, so we expect the 
monitoring requirement will not increase burden appreciably. The 
recordkeeping requirements are new and specific to documenting relevant 
times of off blast so facilities can demonstrate compliance with the 
new work practice standards. Semiannual reporting of deviations is 
required in the major source NESAHP, so reporting of deviations from 
the new work practice standards is also required. We determined that 
these additional requirements were the minimum necessary to demonstrate 
compliance with the new work practice standards for VOHAP from cupola 
furnaces during periods of off blast.
    For the reasons detailed in section IV.C.3 of this preamble, we are 
finalizing these new work practice standards in the major source NESHAP 
during cupola startup and shutdown and providing 180 days to comply 
with these new requirements. During this 180-day transition period, 
major source foundry owners or operators must operate according to 
their SSM plan and we are retaining these specific SSM provisions in 
the major source NESHAP at 40 CFR 63.7720(a) and (c) for the 180-day 
transition period. We determined 180 days to be the most expeditious 
compliance period practicable to implement operational changes. For 
affected sources that commence construction or reconstruction after the 
effective date of these amendments, they must be in compliance with all 
emission limitations, including the new work practice standards, upon 
startup because additional time is not needed for these sources.

D. Electronic Reporting

1. What did we propose?
    We proposed amendments to the major and area source Iron and Steel 
Foundries NESHAP to require foundry owners or operators to submit 
electronic copies of initial notifications, notifications of compliance 
status, performance test reports, performance evaluation reports, and 
semiannual reports through the EPA's Central Data Exchange (CDX) using 
CEDRI. Additionally, we proposed two broad circumstances in which 
electronic reporting extensions may be provided at the discretion of 
the Administrator. The EPA proposed these extensions to protect owners 
or operators from noncompliance in cases where they are unable to 
successfully submit a report by the reporting deadline for reasons 
outside of their control, including CDX and CEDRI outages and force 
majeure events, such as acts of nature, war, or terrorism.
2. What changed since proposal?
    We determined that no changes were necessary to the proposed 
requirements for foundry owners or operators to submit initial 
notifications, notifications of compliance status, performance test 
reports, performance evaluation reports, and semiannual reports 
electronically using CEDRI. Therefore, we are finalizing the electronic 
reporting provisions as proposed (84 FR 54419, October 9, 2019).

[[Page 56092]]

3. What are the key comments and what are our responses?
    Comment: The EPA received one comment generally supporting the 
proposed amendment to require electronic reporting but asserting that 
the force majeure language should be removed. The commenter expressed 
concern that the force majeure provisions violate the requirement for 
standards to be continuous and that they would allow unreported 
exceedances to go unchecked indefinitely.
    Response: Regarding the force majeure provisions, we disagree that 
the ability to request a reporting extension would create a mechanism 
that owners or operators could use to evade binding emissions standards 
or provide a mechanism where those emission standards do not apply at 
all times. Also, we note that there is no exception or exemption to 
reporting, only a method for requesting an extension of the reporting 
deadline. There is no predetermined timeframe for the length of 
extension that can be granted, as this is something best determined by 
the Administrator when reviewing the circumstances surrounding the 
request. Different circumstances may require a different length of 
extension for electronic reporting. For example, a tropical storm may 
delay electronic reporting for a day, but a category 5 hurricane event 
may delay electronic reporting much longer, especially if the facility 
has no power, and, as such, the owner or operator has no ability to 
access electronically stored data or to submit reports electronically. 
The Administrator will be the most knowledgeable on the events leading 
to the request for extension and will assess whether an extension is 
appropriate and, if so, determine a reasonable length. The 
Administrator may even request that the report be sent in hard copy 
until electronic reporting can be resumed. While no new fixed duration 
deadline is set, the regulation does require that the report be 
submitted electronically as soon as possible after the CEDRI outage is 
resolved or after the force majeure event occurs.
    Comment: One commenter stated that electronic reporting through 
CEDRI should not be required for states delegated to administer/enforce 
the NESHAP, unless electronic reporting is specifically required by the 
state.
    Response: Regarding having delegated states determine whether 
electronic reporting is required, we note that the delegation of 
authority to states does not relieve facilities of their obligation to 
report to the EPA per 40 CFR 63.13(a), which requires all requests, 
reports, applications, submittals, and other communications shall be 
submitted to the appropriate Regional office of the EPA. In the case of 
the electronic reporting, those obligations are met through the 
submission to CEDRI. We are retaining the requirement to report through 
CEDRI for all reporters, as proposed. To clarify that electronic 
submission when required by regulation meets the requirement of 40 CFR 
63.13(a), Table 1 of subpart EEEEE and Table 3 of ZZZZZ have been 
amended to specify in the explanation column that ``Except: reports and 
notifications required to be submitted to CEDRI meet this obligation 
through electronic reporting.''
4. What is the rationale for our final approach to electronic 
reporting?
    We are finalizing as proposed a requirement in both the area source 
NESHAP and major source NESHAP that owners or operators of iron and 
steel foundries submit electronic copies of notifications, performance 
evaluation reports, and semiannual compliance reports using CEDRI. We 
also are 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). 
Based on public comments received, we are finalizing an additional 
revision to the General Provision tables (Table 1 to subpart EEEEE and 
Table 3 to subpart ZZZZZ) to add a specific entry for 40 CFR 63.13(a), 
and clarifying in the explanation column that electronic submissions to 
CEDRI meet the reporting requirement at 40 CFR 63.13(a). These 
amendments will increase the ease and efficiency of data submittal for 
owners and operators of iron and steel foundries and will make the data 
more accessible to regulators and the public.

E. Technical and Editorial Corrections

1. What did we propose?
    We proposed one editorial correction for 40 CFR part 63, subpart 
EEEEE, to revise 40 CFR 63.7732(e)(1) to correct the reference to 
``paragraphs (b)(1)(i) through (v)'' to be ``paragraphs (e)(1)(i) 
through (v).''
    We proposed several technical and editorial corrections for 40 CFR 
part 63, subpart ZZZZZ as follows.
     To match requirements in 40 CFR part 63, subpart EEEEE, 
revise 40 CFR 63.10885(a)(1) to add the sentence: ``Any post-consumer 
engine blocks, post-consumer oil filters, or oily turnings that are 
processed and/or cleaned to the extent practicable such that the 
materials do not include lead components, mercury switches, chlorinated 
plastics, or free organic liquids can be included in this 
certification.''
     Revise 40 CFR 63.10890(c) to correct the reference to 
``Sec.  63.9(h)(1)(i)'' to be ``Sec.  63.9(h)(2)(i).''
     Revise 40 CFR 63.10890(f) to correct the reference to 
``Sec.  63.10(e)'' to be ``Sec.  63.13.''
     Revise 40 CFR 63.10897(d)(3) and (g) to replace all 
instances of ``correction action'' with ``corrective action'' to 
correct typographical errors.
     Revise 40 CFR 63.10899(c) to correct the reference to 
``Sec.  63.10(e)'' to be ``Sec.  63.13.''
     To match requirements in 40 CFR part 63, subpart EEEEE, 
revise the entry for 40 CFR 63.9 in Table 3 to subpart ZZZZZ to add an 
explanation in column 4 to read ``Except for opacity performance 
tests.''
2. What changed since proposal?
    We determined that no changes were necessary to the proposed 
technical and editorial corrections outlined above. Therefore, we are 
finalizing these technical and editorial corrections with no changes 
(84 FR 54420, October 9, 2019). We did receive notification of a 
typographical error in 40 CFR 63.10897(d)(1)(i) of subpart ZZZZZ, which 
specifies detection limits for bag leak detectors. The detectors must 
be capable of detecting emissions of PM at concentrations of 10 
milligrams per actual cubic meter. This requirement includes a 
parenthetical providing the limit in units of grains per actual cubic 
feet. Unfortunately, in the area source rule, the limit in units of 
grains per actual cubic feet included a typographical error, listing it 
as 0.00044 rather than 0.0044 grains per actual cubic feet. The correct 
unit conversion for 10 milligrams per actual cubic meter is 0.0044 
grains per actual cubic feet. The correct value is included in the 
major source rule at 40 CFR 63.7741(b)(1). Based on the identification 
of this additional typographical error, we are finalizing revision of 
40 CFR 63.10897(d)(1)(i) to revise the parenthetical from ``(0.00044 
grains per actual cubic foot)'' to ``(0.0044 grains per actual cubic 
foot).''
3. What are the key comments and what are our responses?
    The EPA did not receive any comments on the proposed technical and 
editorial corrections.

[[Page 56093]]

4. What is the rationale for our final approach to technical and 
editorial corrections?
    We identified necessary technical and editorial corrections and 
received no comments except for the identification of a typographical 
error (discussed above) at 40 CFR 63.10897(d)(1)(i) in subpart ZZZZZ. 
Therefore, we are finalizing the revisions, including correction of the 
typographical error in order to correct and clarify the requirements in 
the rules.

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

A. What are the affected sources?

    There are approximately 45 major source iron and steel foundries 
subject to 40 CFR part 63, subpart EEEEE, and approximately 390 area 
source iron and steel foundries subject to 40 CFR part 63, subpart 
ZZZZZ.

B. What are the air quality impacts?

    Because we are not revising the emission limitations for iron and 
steel foundries other than the new work practice standards for VOHAP 
for major sources during startup and shutdown for cupola melting 
furnaces, we do not anticipate any quantifiable air quality impacts as 
a result of the final amendments. However, since the final amendments 
include the removal of the SSM exemptions for both major and area 
sources and the addition of new work practice standards for cupola 
startup and shutdown for major sources, this final rule may reduce 
emissions by an unquantified amount by ensuring proper operation of 
control devices and other measures during SSM periods.

C. What are the cost impacts?

    We expect that the final amendments will have minimal cost impacts 
for iron and steel foundries. The final editorial corrections will have 
no cost impacts. The final revisions to use electronic reporting 
effectively replace existing requirements to mail in copies of the 
required reports and notifications. We expect that the electronic 
system will save some time and expense compared to printing and mailing 
the required reports and notifications; however, it will take some time 
for foundry owners or operators to review the new electronic 
notification and reporting form, review their recordkeeping processes, 
and potentially revise their processes to more efficiently complete 
their semiannual reports. There may also be initial costs associated 
with electronic reporting of performance tests. We are also finalizing 
revisions to SSM provisions. Again, these revisions are expected to 
have minimal impact on affected iron and steel foundries. For major 
source iron and steel foundries, we are eliminating the need to develop 
a SSM plan or submit an immediate SSM report when the SSM plan is not 
followed and there is an exceedance of an applicable emission 
limitation. While this may reduce some burden, iron and steel foundry 
owners or operators will still need to assess their operations and make 
plans to achieve the emission limitations at all times, including 
periods of startup, shutdown, or malfunction. Additionally, we are 
adding new recordkeeping requirements for major source foundries 
related to cupola off blast periods, which includes cupola startup, 
shutdown, and idling periods to demonstrate compliance with the new 
work practice standards.
    For the 45 major source iron and steel foundries subject to 40 CFR 
part 63, subpart EEEEE, we estimate the first-year costs associated 
with the final electronic reporting and SSM revisions will be $107,000 
or approximately $2,380 per major source foundry. This includes one-
time costs to learn the electronic reporting templates and set up 
recordkeeping systems to work with the electronic reporting, one-time 
costs for facilities that conducted a source test to learn the 
electronic reporting system for submitting performance tests, and costs 
associated with the new recordkeeping requirements for the work 
practice standards to reduce cupola VOHAP emissions while off blast. As 
performance tests are required every 5 years, we expect facilities will 
continue to incur additional costs for reporting performance test 
results, since facilities reporting performance test results in Year 2, 
3, 4, or 5 would be using that system for the first time. For Years 2 
and on, owners or operators of major source foundries will incur annual 
costs associated with recordkeeping requirements for the work practice 
standards to reduce cupola VOHAP emissions while off blast, but they 
will also realize some cost savings for semiannual reporting due to 
efficiencies achieved once they adapt to the new electronic reporting 
system. We estimate the nationwide annual costs for Years 2 through 5 
would be approximately $32,500 per year or $720 per year per major 
source foundry.
    For the 390 area source foundries subject to 40 CFR part 63, 
subpart ZZZZZ, we estimate the total first year costs associated with 
the final electronic reporting and SSM revisions will be $352,000 or 
approximately $900 per area source foundry. This includes one-time 
costs to learn the electronic reporting templates and set up 
recordkeeping systems to work with the electronic reporting and, for 
large area source foundries only, one-time costs to learn the 
electronic reporting system for submitting performance tests for those 
facilities that conducted a performance test. Because performance tests 
are required every 5 years, we expect a portion of the large area 
source foundries will continue to incur additional costs for reporting 
performance test results, since facilities reporting performance test 
results in Year 2, 3, 4, or 5 would be using that system for the first 
time. For Years 2 and on, all area source foundries will also realize 
some cost savings for semiannual reporting due to efficiencies achieved 
once facilities adapt to the new electronic reporting system. We 
estimate that all area source will realize a net cost savings for Years 
2 and on and that the cumulative saving across all area source 
foundries would be $67,400 per year or a savings of $170 per year per 
area source foundry.

D. What are the economic impacts?

    Economic impact analyses focus on changes in market prices and 
output levels. If changes in market prices and output levels in the 
primary markets are significant enough, impacts on other markets may 
also be examined. Both the magnitude of costs needed to comply with a 
final rule and the distribution of these costs among affected 
facilities can have a role in determining how the market will change in 
response to a final rule. Because the costs associated with the final 
revisions are minimal, no significant economic impacts are anticipated 
as a result of the final amendments.

E. What are the benefits?

    The final amendments will result in improvements to the rule. 
Specifically, the final amendments revise the standards to reflect that 
they apply at all times. Additionally, the final amendments requiring 
electronic submittal of initial notifications, performance test 
results, and semiannual reports will increase the usefulness of the 
data, are in keeping with current trends of data availability, will 
further assist in the protection of public health and the environment, 
and will ultimately result in less burden on the regulated community. 
The final technical and editorial corrections improve the clarity of 
the rule.

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, we performed a 
demographic analysis, which is an assessment of risks to individual 
demographic groups of the populations living within 5 kilometers (km) 
and within 50 km of the facilities. In the analysis, we evaluated the 
distribution of HAP-related cancer and noncancer risks from the major 
source Iron and Steel Foundries source category across different 
demographic groups within the populations living near facilities.\15\
---------------------------------------------------------------------------

    \15\ 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 major source Iron and Steel Foundries source 
category demographic analysis indicate that emissions from the source 
category expose approximately 144,000 people to a cancer risk at or 
above 1-in-1 million and zero people to a chronic noncancer hazard 
index greater than or equal to 1. The African American population 
exposed to a cancer risk at or above 1-in-1 million due to iron and 
steel foundries emissions is 4 percent above the national average. 
Likewise, populations living ``Below Poverty Level'' and ``Over 25 and 
without High School Diploma'' are exposed to cancer risk above 1-in-1 
million, 6 and 4 percent above the national average, respectively. The 
percentages of the at-risk population in other demographic groups are 
similar to or lower than their respective nationwide percentages. 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 Iron and Steel 
Foundries, available as Docket Item No. EPA-HQ-OAR-2019-0373-0020.

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 health risk assessments for this action are contained the document 
titled Residual Risk Assessment for the Iron and Steel Foundries Major 
Source Category in Support of the 2020 Risk and Technology Review Final 
Rule, available in the docket (Docket ID No. EPA-HQ-OAR-2019-0373).

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 Orders 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 final rule have been 
submitted for approval to OMB under the PRA.
1. Iron and Steel Foundries Major Sources
    The information collection request (ICR) document that the EPA 
prepared has been assigned EPA ICR number 2096.09. 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.
    We are finalizing amendments that require electronic reporting, 
remove the malfunction exemption, and impose other revisions that 
affect reporting and recordkeeping for iron and steel foundries major 
source facilities. This information will be collected to assure 
compliance with 40 CFR part 63, subpart EEEEE.
    Respondents/affected entities: Owners or operators of iron and 
steel foundries major source facilities.
    Respondent's obligation to respond: Mandatory (40 CFR part 63, 
subpart EEEEE).

    Frequency of response: Initial, semiannual, and annual.
    Total estimated burden: The annual recordkeeping and reporting 
burden for facilities to comply with all of the requirements in the 
NESHAP is estimated to be 15,400 hours (per year). Burden is defined at 
5 CFR 1320.3(b).
    Total estimated cost: The annual recordkeeping and reporting burden 
for facilities to comply with all of the requirements in the NESHAP is 
estimated to be $1,440,000 (per year), which includes $206,000 
annualized capital or O&M costs.
2. Iron and Steel Foundries Area Sources
    The ICR document that the EPA prepared has been assigned EPA ICR 
number 2267.07. 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.
    We are finalizing amendments that require electronic reporting, 
remove the malfunction exemption, and impose other revisions that 
affect reporting and recordkeeping for iron and steel foundries area 
source facilities. This information will be collected to assure 
compliance with 40 CFR part 63, subpart ZZZZZ.
    Respondents/affected entities: Owners or operators of iron and 
steel foundries area source facilities.
    Respondent's obligation to respond: Mandatory (40 CFR part 63, 
subpart ZZZZZ).
    Estimated number of respondents: 390 (total), 75 of these are 
classified as large iron and steel foundries and 315 are classified as 
small iron and steel foundries.
    Frequency of response: Initial, semiannual, and annual.
    Total estimated burden: The annual recordkeeping and reporting 
burden for facilities to comply with all of the requirements in the 
NESHAP is estimated to be 14,400 hours (per year). Burden is defined at 
5 CFR 1320.3(b).
    Total estimated cost: The annual recordkeeping and reporting burden 
for facilities to comply with all of the requirements in the NESHAP is 
estimated to be $1,150,000 (per year); there are no annualized capital 
or O&M costs.
    An agency may not conduct or sponsor, and a person is not required 
to respond to, a collection of information

[[Page 56095]]

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. In 
making this determination, the impact of concern is any significant 
adverse economic impact on small entities. An agency may certify that a 
rule will not have a significant economic impact on a substantial 
number of small entities if the rule relieves regulatory burden, has no 
net burden or otherwise has a positive economic effect on the small 
entities subject to the rule. The final amendments have a very limited 
one-time burden as affected facilities implement electronic reporting 
for the first time, but affected facilities will see a net cost savings 
in subsequent years that will off-set the initial one-time costs within 
the first 3 years after implementation. We have, therefore, concluded 
that this action will have no net regulatory burden for all directly 
regulated small entities.

E. Unfunded Mandates Reform Act (UMRA)

    This action does not contain an unfunded mandate of $100 million or 
more as described in UMRA, 2 U.S.C. 1531-1538, and does not 
significantly or uniquely affect small governments. While this action 
creates an enforceable duty on the private sector, the cost does not 
exceed $100 million or more.

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 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.A and IV.A of this preamble. Further documentation is 
provided in the following risk report titled Residual Risk Assessment 
for the Iron and Steel Foundries Major Source Category in Support of 
the 2020 Risk and Technology Review Final Rule, which can be found in 
the docket for this action.

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)

    This rulemaking does not involve technical standards.

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 contained in the technical report 
titled Risk and Technology Review--Analysis of Demographic Factors for 
Populations Living Near Iron and Steel Foundries, available as Docket 
Item No. EPA-HQ-OAR-2019-0373-0020.

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).

4. Section 63.7710 is amended by revising paragraphs (a) and (b) 
introductory text to read as follows:

Sec.  63.7710   What are my operation and maintenance requirements?

    (a) You must always operate and maintain your iron and steel 
foundry, including air pollution control and monitoring equipment, in a 
manner consistent with good air pollution control practices for 
minimizing emissions at least to the levels required by this subpart.
    (b) You must prepare and operate at all times according to a 
written operation and maintenance plan for each capture and collection 
system and control device for an emissions source subject to a PM, 
metal HAP, TEA, or VOHAP emissions limit in Sec.  63.7690(a) or the 
work practice standards in Sec.  63.7700(g). Your operation and 
maintenance plan also must include procedures for igniting gases from 
mold vents in pouring areas and pouring stations that use a sand mold 
system. This operation and maintenance plan is subject to approval by 
the Administrator. Each plan must contain the elements described in 
paragraphs (b)(1) through (6) of this section.
* * * * *

5. Section 63.7720 is amended by revising paragraphs (a) and (c) to 
read as follows:

Sec.  63.7720   What are my general requirements for complying with 
this subpart?

    (a) On and before March 9, 2021, for affected sources that 
commenced construction or reconstruction on or before September 10, 
2020, you must be in compliance with the emissions limitations, work 
practice standards, and operation and maintenance requirements in this 
subpart at all times, except during periods of startup and shutdown. 
After March 9, 2021, for affected sources that commenced construction 
or reconstruction on or before September 10, 2020, and upon startup for 
affected sources that commenced construction or reconstruction after

    (e) Compliance report submission requirements. Prior to March 9, 
2021, you must submit semiannual compliance reports to the 
Administrator as specified in Sec.  63.13. Beginning on March 9, 2021, 
you must submit all subsequent semiannual compliance reports to the EPA 
via the Compliance and Emissions Data Reporting Interface (CEDRI), 
which can be accessed through the EPA's Central Data Exchange (CDX) 
(https://cdx.epa.gov/). The EPA will make all the information submitted 
through CEDRI available to the public without further notice to you. Do 
not use CEDRI to submit information you claim as confidential business 
information (CBI). Anything submitted using CEDRI cannot later be 
claimed to be CBI. You must use the appropriate electronic report 
template on the CEDRI website (https://www.epa.gov/electronic-reporting-air-emissions/cedri) for this subpart. The date report 
templates become available will be listed on the CEDRI website. The 
report must be submitted by the deadline specified in this subpart, 
regardless of the method in which the report is submitted. If you claim 
some of the information required to be submitted via CEDRI is CBI, 
submit a complete report, including information claimed to be CBI, to 
the EPA. The report must be generated using the appropriate form on the 
CEDRI website or an alternate electronic file consistent with the 
extensible markup language (XML) schema listed on the CEDRI website. 
Although we do not expect persons to assert a claim of CBI, if persons 
wish to assert a CBI, submit the file on a compact disc, flash drive, 
or other commonly used electronic storage medium and clearly mark the 
medium as CBI. Mail the electronic medium to U.S. EPA/OAQPS/CORE CBI 
Office, Attention: Group Leader, Measurement Policy Group, MD C404-02, 
4930 Old Page Rd., Durham, NC 27703. The same file with the CBI omitted 
must be submitted to the EPA via the EPA's CDX

[[Page 56098]]

as described earlier in this paragraph (e). All CBI claims must be 
asserted at the time of submission. Furthermore, under CAA section 
114(c) emissions data is not entitled to confidential treatment and 
requires EPA to make emissions data available to the public. Thus, 
emissions data will not be protected as CBI and will be made publicly 
available.
    (f) Performance test results submission requirements. Within 60 
days after the date of completing each performance test required by 
this subpart, you must submit the results of the performance test 
following the procedures specified in paragraphs (f)(1) through (3) of 
this section.
    (1) Data collected using test methods supported by the EPA's 
Electronic Reporting Tool (ERT) as listed on the EPA's ERT website 
(https://www.epa.gov/electronic-reporting-air-emissions/electronic-reporting-tool-ert) at the time of the test. Submit the results of the 
performance test to the EPA via the CEDRI, which can be accessed 
through the EPA's CDX (https://cdx.epa.gov/). The data must be 
submitted in a file format generated through the use of the EPA's ERT. 
Alternatively, you may submit an electronic file consistent with the 
XML schema listed on the EPA's ERT website.
    (2) Data collected using test methods that are not supported by the 
EPA's ERT as listed on the EPA's ERT website at the time of the test. 
The results of the performance test must be included as an attachment 
in the ERT or an alternate electronic file consistent with the XML 
schema listed on the EPA's ERT website. Submit the ERT generated 
package or alternative file to the EPA via CEDRI.
    (3) Confidential business information. The EPA will make all the 
information submitted through CEDRI available to the public without 
further notice to you. Do not use CEDRI to submit information you claim 
as CBI. Anything submitted using CEDRI cannot later be claimed to be 
CBI. Although we do not expect persons to assert a claim of CBI, if you 
claim some of the information submitted under paragraph (f)(1) or (2) 
of this section is CBI, you must submit a complete file, including 
information claimed to be CBI, to the EPA. The file must be generated 
through the use of the EPA's ERT or an alternate electronic file 
consistent with the XML schema listed on the EPA's ERT website. Submit 
the file on a compact disc, flash drive, or other commonly used 
electronic storage medium and clearly mark the medium as CBI. Mail the 
electronic medium to U.S. EPA/OAQPS/CORE CBI Office, Attention: Group 
Leader, Measurement Policy Group, MD C404-02, 4930 Old Page Rd., 
Durham, NC 27703. The same file with the CBI omitted must be submitted 
to the EPA via the EPA's CDX as described in paragraph (f)(1) of this 
section. All CBI claims must be asserted at the time of submission. 
Furthermore, under CAA section 114(c) emissions data is not entitled to 
confidential treatment and requires EPA to make emissions data 
available to the public. Thus, emissions data will not be protected as 
CBI and will be made publicly available.
    (g) Performance evaluation results submission requirements. Within 
60 days after the date of completing each continuous monitoring system 
(CMS) performance evaluation (as defined in Sec.  63.2), you must 
submit the results of the performance evaluation following the 
procedures specified in paragraphs (g)(1) through (3) of this section.
    (1) Performance evaluations of CMS measuring relative accuracy test 
audit (RATA) pollutants that are supported by the EPA's ERT as listed 
on the EPA's ERT website at the time of the evaluation. Submit the 
results of the performance evaluation to the EPA via CEDRI, which can 
be accessed through the EPA's CDX. The data must be submitted in a file 
format generated through the use of the EPA's ERT. Alternatively, you 
may submit an electronic file consistent with the XML schema listed on 
the EPA's ERT website.
    (2) Performance evaluations of CMS measuring RATA pollutants that 
are not supported by the EPA's ERT as listed on the EPA's ERT website 
at the time of the evaluation. The results of the performance 
evaluation must be included as an attachment in the ERT or an alternate 
electronic file consistent with the XML schema listed on the EPA's ERT 
website. Submit the ERT generated package or alternative file to the 
EPA via CEDRI.
    (3) Confidential business information. The EPA will make all the 
information submitted through CEDRI available to the public without 
further notice to you. Do not use CEDRI to submit information you claim 
as CBI. Anything submitted using CEDRI cannot later be claimed to be 
CBI. Although we do not expect persons to assert a claim of CBI, if you 
claim some of the information submitted under paragraph (g)(1) or (2) 
of this section is CBI, you must submit a complete file, including 
information claimed to be CBI, to the EPA. The file must be generated 
through the use of the EPA's ERT or an alternate electronic file 
consistent with the XML schema listed on the EPA's ERT website. Submit 
the file on a compact disc, flash drive, or other commonly used 
electronic storage medium and clearly mark the medium as CBI. Mail the 
electronic medium to U.S. EPA/OAQPS/CORE CBI Office, Attention: Group 
Leader, Measurement Policy Group, MD C404-02, 4930 Old Page Rd., 
Durham, NC 27703. The same file with the CBI omitted must be submitted 
to the EPA via the EPA's CDX as described in paragraph (g)(1) of this 
section. All CBI claims must be asserted at the time of submission. 
Furthermore, under CAA section 114(c) emissions data is not entitled to 
confidential treatment and requires EPA to make emissions data 
available to the public. Thus, emissions data will not be protected as 
CBI and will be made publicly available.
    (h) Claims of EPA system outage. If you are required to 
electronically submit a report through CEDRI in the EPA's CDX, you may 
assert a claim of EPA system outage for failure to timely comply with 
the reporting requirement. To assert a claim of EPA system outage, you 
must meet the requirements outlined in paragraphs (h)(1) through (7) of 
this section.
    (1) You must have been or will be precluded from accessing CEDRI 
and submitting a required report within the time prescribed due to an 
outage of either the EPA's CEDRI or CDX systems.
    (2) The outage must have occurred within the period of time 
beginning five business days prior to the date that the submission is 
due.
    (3) The outage may be planned or unplanned.
    (4) You must submit notification to the Administrator in writing as 
soon as possible following the date you first knew, or through due 
diligence should have known, that the event may cause or has caused a 
delay in reporting.
    (5) You must provide to the Administrator a written description 
identifying:
    (i) The date(s) and time(s) when CDX or CEDRI was accessed and the 
system was unavailable;
    (ii) A rationale for attributing the delay in reporting beyond the 
regulatory deadline to EPA system outage;
    (iii) Measures taken or to be taken to minimize the delay in 
reporting; and
    (iv) The date by which you propose to report, or if you have 
already met the reporting requirement at the time of the notification, 
the date you reported.
    (6) The decision to accept the claim of EPA system outage and allow 
an extension to the reporting deadline is solely within the discretion 
of the Administrator.
    (7) In any circumstance, the report must be submitted 
electronically as

[[Page 56099]]

soon as possible after the outage is resolved.
    (i) Claims of force majeure. If you are required to electronically 
submit a report through CEDRI in the EPA's CDX, you may assert a claim 
of force majeure for failure to timely comply with the reporting 
requirement. To assert a claim of force majeure, you must meet the 
requirements outlined in paragraphs (i)(1) through (5) of this section.
    (1) You may submit a claim if a force majeure event is about to 
occur, occurs, or has occurred or there are lingering effects from such 
an event within the period of time beginning five business days prior 
to the date the submission is due. For the purposes of this section, a 
force majeure event is defined as an event that will be or has been 
caused by circumstances beyond the control of the affected facility, 
its contractors, or any entity controlled by the affected facility that 
prevents you from complying with the requirement to submit a report 
electronically within the time period prescribed. Examples of such 
events are acts of nature (e.g., hurricanes, earthquakes, or floods), 
acts of war or terrorism, or equipment failure or safety hazard beyond 
the control of the affected facility (e.g., large scale power outage).
    (2) You must submit notification to the Administrator in writing as 
soon as possible following the date you first knew, or through due 
diligence should have known, that the event may cause or has caused a 
delay in reporting.
    (3) You must provide to the Administrator:
    (i) A written description of the force majeure event;
    (ii) A rationale for attributing the delay in reporting beyond the 
regulatory deadline to the force majeure event;
    (iii) Measures taken or to be taken to minimize the delay in 
reporting; and
    (iv) The date by which you propose to report, or if you have 
already met the reporting requirement at the time of the notification, 
the date you reported.
    (4) The decision to accept the claim of force majeure and allow an 
extension to the reporting deadline is solely within the discretion of 
the Administrator.
    (5) In any circumstance, the reporting must occur as soon as 
possible after the force majeure event occurs.

14. Section 63.7765 is amended by adding in alphabetical order the 
definitions for ``Cupola shutdown'' and ``Cupola startup'' and revising 
the definitions for ``Deviation'' (including the undesignated paragraph 
following the definition) and ``Off blast'' to read as follows:

Sec.  63.7765   What definitions apply to this subpart?

* * * * *
    Cupola shutdown means the period beginning when the last of the 
molten metal is tapped from the cupola's primary tap hole and ending 
when the cupola is cooled and the cupola is either banked or the bottom 
contents are removed (``bottom drop''). Cupola shutdown includes the 
following steps: slag and residual metal removal from secondary tap; 
cupola cooling; and cupola banking or bottom drop.
    Cupola startup means the commencement of activities needed to take 
a banked cupola or a cupola that has had the bottom dropped back into 
melt production. Cupola startup includes the following steps: 
refractory curing, if needed; cupola bed preparation (during which the 
sand bed is preheated), if needed; coke bed preparation (during which 
coke is added to the cupola and lit); and initial metallics charging.
    Deviation means any instance in which an affected source or an 
owner or operator of such an affected source:
    (1) Fails to meet any requirement or obligation established by this 
subpart including, but not limited to, any emissions limitation 
(including operating limits), work practice standard, or operation and 
maintenance requirement; or
    (2) Fails to meet any term or condition that is adopted to 
implement an applicable requirement in this subpart and that is 
included in the operating permit for any iron and steel foundry 
required to obtain such a permit.
    (3) A deviation is not always a violation. The determination of 
whether a deviation constitutes a violation of the standard is up to 
the discretion of the entity responsible for enforcement of the 
standards.
* * * * *
    Off blast means those periods of cupola operation when the cupola 
is not actively being used to produce molten metal. Off blast 
conditions include

[[Page 56100]]

cupola startup and cupola shutdown. Off blast conditions also include 
idling conditions when the blast air is turned off or down to the point 
that the cupola does not produce additional molten metal.

16. Section 63.10885 is amended by revising paragraph (a)(1) to read as 
follows:

Sec.  63.10885   What are my management practices for metallic scrap 
and mercury switches?

    (a) * * *
    (1) Restricted metallic scrap. You must prepare and operate at all 
times according to written material specifications for the purchase and 
use of only metal ingots, pig iron, slitter, or other materials that do 
not include post-consumer automotive body scrap, post-consumer engine 
blocks, post-consumer oil filters, oily turnings, lead components, 
chlorinated plastics, or free liquids. For the purpose of this subpart, 
``free liquids'' is defined as material that fails the paint filter 
test by EPA Method 9095B, ``Paint Filter Liquids Test'' (revision 2), 
November 2004 (incorporated by reference--see Sec.  63.14). The 
requirements for no free liquids do not apply if the owner or operator 
can demonstrate that the free liquid is water that resulted from scrap 
exposure to rain. Any post-consumer engine blocks, post-consumer oil 
filters, or oily turnings that are processed and/or cleaned to the 
extent practicable such that the materials do not include lead 
components, mercury switches, chlorinated plastics, or free organic 
liquids can be included in this certification.

17. Section 63.10890 is amended by revising paragraphs (c) introductory 
text, (d), (e)(3), (f), and (i) and adding paragraph (j) to read as 
follows:

Sec.  63.10890   What are my management practices and compliance 
requirements?

* * * * *
    (c) You must submit a notification of compliance status according 
to Sec.  63.9(h)(2)(i). You must send the notification of compliance 
status before the close of business on the 30th day after the 
applicable compliance date specified in Sec.  63.10881. The 
notification must include the following compliance certifications, as 
applicable:
* * * * *
    (d) As required by Sec.  63.10(b)(1), you must maintain files of 
all information (including all reports and notifications) for at least 
5 years following the date of each occurrence, measurement, 
maintenance, corrective action, report, or record. At a minimum, the 
most recent 2 years of data shall be retained on site. The remaining 3 
years of data may be retained off site. Such files may be maintained on 
microfilm, on a computer, on computer floppy disks, on magnetic tape 
disks, or on microfiche. Any records required to be maintained by this 
part that are submitted electronically via the EPA's Compliance and 
Emissions Data Reporting Interface (CEDRI) may be maintained in 
electronic format. This ability to maintain electronic copies does not 
affect the requirement for facilities to make records, data, and 
reports available upon request to a delegated air agency or the EPA as 
part of an on-site compliance evaluation.

all information (including all reports and notifications) for at least 
5 years following the date of each occurrence, measurement, 
maintenance, corrective action, report, or record. At a minimum, the 
most recent 2 years of data shall be retained on site. The remaining 3 
years of data may be retained off site. Such files may be maintained on 
microfilm, on a computer, on computer floppy disks or flash drives, on 
magnetic tape disks, or on microfiche. Any records required to be 
maintained by this part that are submitted electronically via the EPA's 
CEDRI may be maintained in electronic format. This ability to maintain 
electronic copies does not affect the requirement for facilities to 
make records, data, and reports available upon request to a delegated 
air agency or the EPA as part of an on-site compliance evaluation.
    (b) In addition to the records required by Sec.  63.10(b)(2)(iii) 
and (vi) through (xiv) and (b)(3), you must keep records of the 
information specified in paragraphs (b)(1) through (15) of this 
section.
* * * * *
    (2) If you are subject to the requirements for a site-specific plan 
for mercury under Sec.  63.10885(b)(1), you must maintain records of 
the number of mercury switches removed or the weight of mercury 
recovered from the switches and properly managed, the estimated number 
of vehicles processed, and an estimate of the percent of mercury 
switches recovered.
* * * * *
    (14) You must keep records of the site-specific performance 
evaluation test plan required under Sec.  63.8(d)(2) for the life of 
the affected source or until the affected source is no longer subject 
to the provisions of this part, to be made available for inspection, 
upon request, by the Administrator. If the performance evaluation plan 
is revised, you shall keep previous (i.e., superseded) versions of the 
performance evaluation plan on record to be made available for 
inspection, upon request, by the Administrator, for a period of 5 years 
after each revision to the plan. The program of corrective action 
should be included in the plan as required under Sec.  63.8(d)(2)(vi).
    (15) You must keep the following records for each failure to meet 
an emissions limitation (including operating limit), work practice 
standard, or operation and maintenance requirement in this subpart.
    (i) Date, start time, and duration of each failure.
    (ii) List of the affected sources or equipment for each failure, an 
estimate of the quantity of each regulated pollutant emitted over any 
emission limit and a description of the method used to estimate the 
emissions.
    (iii) Actions taken to minimize emissions in accordance with Sec.  
63.10896(c), and any corrective actions taken to return the affected 
unit to its normal or usual manner of operation.
    (c) Prior to March 9, 2021, you must submit semiannual compliance 
reports to the Administrator according to the requirements in Sec.  
63.13. Beginning on March 9, 2021, you must submit all subsequent 
semiannual compliance reports to the EPA via the CEDRI, which can be 
accessed through the EPA's Central Data Exchange (CDX) (https://cdx.epa.gov/). The EPA will make all the information submitted through 
CEDRI available to the public without further notice to you. Do not use 
CEDRI to submit information you claim as confidential business 
information (CBI). Anything submitted using CEDRI cannot later be 
claimed to be CBI. You must use the appropriate electronic report 
template on the CEDRI website (https://www.epa.gov/electronic-reporting-air-emissions/cedri) for this subpart. The date report 
templates become available

[[Page 56103]]

will be listed on the CEDRI website. The report must be submitted by 
the deadline specified in this subpart, regardless of the method in 
which the report is submitted. Although we do not expect persons to 
assert a claim of CBI, if persons wish to assert a CBI if you claim 
some of the information required to be submitted via CEDRI is CBI, 
submit a complete report, including information claimed to be CBI, to 
the EPA. The report must be generated using the appropriate form on the 
CEDRI website or an alternate electronic file consistent with the 
extensible markup language (XML) schema listed on the CEDRI website. 
Submit the file on a compact disc, flash drive, or other commonly used 
electronic storage medium and clearly mark the medium as CBI. Mail the 
electronic medium to U.S. EPA/OAQPS/CORE CBI Office, Attention: Group 
Leader, Measurement Policy Group, MD C404-02, 4930 Old Page Rd., 
Durham, NC 27703. The same file with the CBI omitted must be submitted 
to the EPA via the EPA's CDX as described earlier in this paragraph 
(c). All CBI claims must be asserted at the time of submission. 
Furthermore, under CAA section 114(c) emissions data is not entitled to 
confidential treatment and requires EPA to make emissions data 
available to the public. Thus, emissions data will not be protected as 
CBI and will be made publicly available. The reports must include the 
information specified in paragraphs (c)(1) through (3) of this section 
and, as applicable, paragraphs (c)(4) through (9) of this section.
    (1) Company name and address.
    (2) Statement by a responsible official, with that official's name, 
title, and signature, certifying the truth, accuracy, and completeness 
of the content of the report.
    (3) Date of report and beginning and ending dates of the reporting 
period.
    (4) If there were no deviations from any emissions limitations

management practices, or operation and maintenance requirements during 
the reporting period.
    (5) If there were no periods during which a continuous monitoring 
system (including a CPMS or continuous emissions monitoring system 
(CEMS) was inoperable or out-of-control as specified by Sec.  
63.8(c)(7), a statement that there were no periods during which the 
CPMS was inoperable or out-of-control during the reporting period.
    (6) For each affected source or equipment for which there was a 
deviation from an emissions limitation (including an operating limit, 
pollution prevention management practice, or operation and maintenance 
requirement) that occurs at an iron and steel foundry during the 
reporting period, the compliance report must contain the information 
specified in paragraphs (c)(6)(i) through (iii) of this section. The 
requirement in this paragraph (c)(6) includes periods of startup, 
shutdown, and malfunction.
    (i) A list of the affected source or equipment and the total 
operating time of each emissions source during the reporting period.
    (ii) For each deviation from an emissions limitation (including an

reporting period across all causes both in hours and as a percent of 
the total source operating time during the reporting period.
    (8) Identification of which option in Sec.  63.10885(b) applies to 
you. If you comply with the mercury requirements in Sec.  63.10885(b) 
by using one scrap provider, contract, or shipment subject to one 
compliance provision and others subject to another compliance provision 
different, provide an identification of which option in Sec.  
63.10885(b) applies to each scrap provider, contract, or shipment.
    (9) If you are subject to the requirements for a site-specific plan 
for mercury under Sec.  63.10885(b)(1), include:
    (i) The number of mercury switches removed or the weight of mercury 
recovered from the switches and properly managed, the estimated number

* * * * *
    (e) Within 60 days after the date of completing each performance 
test required by this subpart, you must

[[Page 56104]]

submit the results of the performance test following the procedures 
specified in paragraphs (e)(1) through (3) of this section.
    (1) Data collected using test methods supported by the EPA's 
Electronic Reporting Tool (ERT) as listed on the EPA's ERT website 
(https://www.epa.gov/electronic-reporting-air-emissions/electronic-reporting-tool-ert) at the time of the test. Submit the results of the 
performance test to the EPA via the CEDRI, which can be accessed 
through the EPA's CDX (https://cdx.epa.gov/). The data must be 
submitted in a file format generated through the use of the EPA's ERT. 
Alternatively, you may submit an electronic file consistent with the 
XML schema listed on the EPA's ERT website.
    (2) Data collected using test methods that are not supported by the 
EPA's ERT as listed on the EPA's ERT website at the time of the test. 
The results of the performance test must be included as an attachment 
in the ERT or an alternate electronic file consistent with the XML 
schema listed on the EPA's ERT website. Submit the ERT generated 
package or alternative file to the EPA via CEDRI.
    (3) Confidential business information. The EPA will make all the 
information submitted through CEDRI available to the public without 
further notice to you. Do not use CEDRI to submit information you claim 
as CBI. Anything submitted using CEDRI cannot later be claimed to be 
CBI. Although we do not expect persons to assert a claim of CBI if you 
claim some of the information submitted under paragraph (e)(1) or (2) 
of this section is CBI, you must submit a complete file, including 
information claimed to be CBI, to the EPA. The file must be generated 
through the use of the EPA's ERT or an alternate electronic file 
consistent with the XML schema listed on the EPA's ERT website. Submit 
the file on a compact disc, flash drive, or other commonly used 
electronic storage medium and clearly mark the medium as CBI. Mail the 
electronic medium to U.S. EPA/OAQPS/CORE CBI Office, Attention: Group 
Leader, Measurement Policy Group, MD C404-02, 4930 Old Page Rd., 
Durham, NC 27703. The same file with the CBI omitted must be submitted 
to the EPA via the EPA's CDX as described in paragraph (e)(1) of this 
section. All CBI claims must be asserted at the time of submission. 
Furthermore, under CAA section 114(c) emissions data is not entitled to 
confidential treatment and requires EPA to make emissions data 
available to the public. Thus, emissions data will not be protected as 
CBI and will be made publicly available.
    (f) If you are required to electronically submit a report through 
CEDRI in the EPA's CDX, you may assert a claim of EPA system outage for 
failure to timely comply with the reporting requirement. To assert a 
claim of EPA system outage, you must meet the requirements outlined in 
paragraphs (f)(1) through (7) of this section.
    (1) You must have been or will be precluded from accessing CEDRI 
and submitting a required report within the time prescribed due to an 
outage of either the EPA's CEDRI or CDX systems.
    (2) The outage must have occurred within the period of time 
beginning 5 business days prior to the date that the submission is due.
    (3) The outage may be planned or unplanned.
    (4) You must submit notification to the Administrator in writing as 
soon as possible following the date you first knew, or through due 
diligence should have known, that the event may cause or has caused a 
delay in reporting.
    (5) You must provide to the Administrator a written description 
identifying:
    (i) The date(s) and time(s) when CDX or CEDRI was accessed and the 
system was unavailable;
    (ii) A rationale for attributing the delay in reporting beyond the 
regulatory deadline to EPA system outage;
    (iii) Measures taken or to be taken to minimize the delay in 
reporting; and
    (iv) The date by which you propose to report, or if you have 
already met the reporting requirement at the time of the notification, 
the date you reported.
    (6) The decision to accept the claim of EPA system outage and allow 
an extension to the reporting deadline is solely within the discretion 
of the Administrator.
    (7) In any circumstance, the report must be submitted 
electronically as soon as possible after the outage is resolved.
    (g) If you are required to electronically submit a report through 
CEDRI in the EPA's CDX, you may assert a claim of force majeure for 
failure to timely comply with the reporting requirement. To assert a 
claim of force majeure, you must meet the requirements outlined in 
paragraphs (g)(1) through (5) of this section.
    (1) You may submit a claim if a force majeure event is about to 
occur, occurs, or has occurred or there are lingering effects from such 
an event within the period of time beginning five business days prior 
to the date the submission is due. For the purposes of this section, a 
force majeure event is defined as an event that will be or has been 
caused by circumstances beyond the control of the affected facility, 
its contractors, or any entity controlled by the affected facility that 
prevents you from complying with the requirement to submit a report 
electronically within the time period prescribed. Examples of such 
events are acts of nature (e.g., hurricanes, earthquakes, or floods), 
acts of war or terrorism, or equipment failure or safety hazard beyond 
the control of the affected facility (e.g., large scale power outage).
    (2) You must submit notification to the Administrator in writing as 
soon as possible following the date you first knew, or through due 
diligence should have known, that the event may cause or has caused a 
delay in reporting.
    (3) You must provide to the Administrator:
    (i) A written description of the force majeure event;
    (ii) A rationale for attributing the delay in reporting beyond the 
regulatory deadline to the force majeure event;
    (iii) Measures taken or to be taken to minimize the delay in 
reporting; and
    (iv) The date by which you propose to report, or if you have 
already met the reporting requirement at the time of the notification, 
the date you reported.
