Air Plan Approval; OR; Regional Haze Plan for the Second 
Implementation Period

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is approving the 
regional haze state implementation plan revision submitted by Oregon on 
April 29, 2022, as supplemented on November 22, 2023, as satisfying 
applicable requirements under the Clean Air Act and the EPA's Regional 
Haze Rule for the program's second implementation period. The Oregon 
submission addressed the requirement that states must periodically 
revise their long-term strategies for making reasonable progress 
towards the national goal of preventing any future, and remedying any 
existing, anthropogenic impairment of visibility, including regional 
haze, in mandatory Class I Federal areas. The Oregon submission also 
addressed other applicable requirements for the second implementation 
period of the regional haze program.

DATES: This final rule is effective November 7, 2024.

I. Background

    On February 23, 2024, the EPA proposed to approve the regional haze 
state implementation plan (SIP) revision submitted by Oregon on April 
29, 2022, as supplemented on November 22, 2023, as satisfying 
applicable requirements under the Clean Air Act (CAA) and the EPA's 
Regional Haze Rule (RHR) for the program's second implementation period 
(89 FR 13622).
    The public comment period for our proposed action was originally 
scheduled to close on March 25, 2024. However, on February 28, 2024, we 
received a request to extend the public comment period an additional 30 
days.\1\ On March 14, 2024, we published a document in the Federal 
Register extending the public comment period end date from March 25, 
2024, to April 24, 2024 (89 FR 18866).
---------------------------------------------------------------------------

    \1\ This extension request letter may be found in the docket for 
this action.
---------------------------------------------------------------------------

    We received four comments. We determined that two comments were not 
germane to our action, for the following reasons. One commenter 
expressed opposition to the cultivation of cannabis, asserting general 
air pollution concerns. The commenter did not provide any tangible 
connection to the regional haze requirements or the Oregon submission. 
The EPA acknowledges the commenter's concerns; however, the comment is 
outside the scope of this action and does not indicate that the EPA's 
approval of the SIP submission is inconsistent with the CAA. Oversight 
of cannabis farms is unrelated to this regional haze action.
    A second commenter cited some details from the Oregon regional haze 
plan, asserting a connection to transmission of the coronavirus. 
However, the commenter provided no logical basis for this assertion. 
The EPA acknowledges the commenter's concerns; however, the comment is 
outside the scope of this action and does not indicate that the EPA's 
approval of the SIP submission is inconsistent with the CAA. Potential 
connections between air pollution and respiratory viruses on public 
health is unrelated to this regional haze action.
    We also received two germane comments. One was submitted by the 
National Park Service (NPS). The second was submitted by Earthjustice 
on behalf of a coalition of environmental organizations consisting of 
Cully Air Action Team, National Parks Conservation Association, 
Neighbors for Clean Air, Northwest Environmental Defense Center, Oregon 
Environmental Council, Sierra Club, and Verde (Environmental 
Organizations). The full text of the comments may be found in the 
docket for this action. We have summarized the comments and provided 
our responses in section II. of this preamble. Under the Clean Air Act, 
the Administrator is required to approve a SIP submission that complies 
with the provisions of the Clean Air Act and applicable Federal 
regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP 
submissions, the EPA's role is to approve state choices, provided that 
they meet the criteria of the Clean Air Act.

II. EPA Responses to Comments Received

A. National Park Service Comments

1. Federal Land Manager Consultation
    Comment: ``[W]e would like to make the EPA aware that the Oregon 
SIP process did not meet the requirements for Federal Land Manager 
(FLM) consultation . . . The NPS participated in early, informal 
engagement with the Oregon Department of Environmental Quality (ODEQ) 
regarding SIP development beginning in January of 2020. This productive 
collaboration included a meeting, subsequent written documentation, and 
staff-to-staff technical feedback on individual facility four-factor 
analyses as documented in the Oregon SIP. The NPS appreciates the 
extensive efforts that Oregon invested in early communication. However, 
many of the draft conclusions and determinations presented to the NPS 
during early engagement were not incorporated into the draft SIP 
released for public review in late August 2021. In fact, the public 
comment draft included substantial changes to the facility-specific 
control determinations in comparison with what the NPS had reviewed 
previously.''
    Response: The EPA disagrees with the commenter's assertion that 
Oregon did not meet the requirements for Federal Land Manager (FLM) 
consultation in 40 CFR 51.308(i). As described below, ODEQ met all of 
the FLM consultation statutory and regulatory requirements.
    Chapter 6.3 Consultations with Federal Land Managers of the April 
29, 2022, SIP revision contained documentation of the extensive 
outreach with the NPS. This included providing a May 5, 2021, draft of 
the regional haze plan explicitly for the purpose of FLM consultation 
(May 2021 FLM draft). A key element of 40 CFR

[[Page 81363]]

51.308(i)(2) is that consultation occur early enough in a state's 
policy analyses of its long-term strategy so that information and 
recommendations provided by the FLMs can meaningfully inform a state's 
decisions on the long-term strategy. Chapters 6.3.3 Federal Land 
Manager Review of Draft State Implementation Plan and 6.3.4 Federal 
Land Manager Comments and DEQ Responses contained Oregon's responses to 
all comments received as part of the May 2021 FLM draft review process 
and prior consultation outreach. The NPS's characterization of this 
effort as ``informal consultation'' is not consistent with the EPA's 
regulations. The requirements of 40 CFR 51.308(i)(2) contain no 
bifurcation of ``informal'' versus ``formal'' consultation. Consistent 
with the preamble of the EPA's 2017 Regional Haze Rule, the Oregon 
Department of Environmental Quality (ODEQ) made a good faith effort to 
involve the NPS early in development of the long-term strategy. The RHR 
preamble specifically states that consultation should be used to inform 
``decisions that are about to be made by the state on its long-term 
strategy . . .'' (emphasis added).\2\ ODEQ used the comments and 
feedback from the May 2021 FLM consultation draft to inform the final 
control determinations contained in the draft provided for public 
notice and comment period starting on August 27, 2021 (August 2021 
public comment draft). The interpretation that all control 
determinations must be finalized before initiating FLM consultation is 
not supported by the text of 40 CFR 51.308(i), nor is it in keeping 
with the intent of 40 CFR 51.308(i) to foster early engagement.
---------------------------------------------------------------------------

    \2\ See 82 FR 3078 (January 10, 2017) at page 3116.
---------------------------------------------------------------------------

    In addition to the May 2021 FLM consultation draft process, ODEQ 
provided opportunity for review and comment on the August 2021 public 
draft. In response to public interest, ODEQ extended the public comment 
period for an additional 30 days, going from August 27, 2021, to 
November 1, 2021, so that all parties had adequate time to review the 
technical determinations. The NPS used this opportunity to provide 
additional comments which are included in Chapter 6.6 Public Comments 
and Responses of the April 29, 2022, SIP revision, along with ODEQ's 
responses to the comments.\3\
---------------------------------------------------------------------------

    \3\ See Oregon's April 29, 2022, submission, pages 136-140 
(comment numbers 6-9).
---------------------------------------------------------------------------

    Also, in response to NPS and Environmental Organizations' concerns, 
ODEQ supplemented the regional haze SIP on November 22, 2023, with 
appendices 1 through 6 (2023 supplement). These appendices contained 
additional correspondence used by ODEQ in making control determinations 
under the statutory four factors for Boise Cascade Wood Products, LLC--
Elgin Complex, Boise Cascade Wood Products, LLC--Medford, Georgia 
Pacific--Wauna Mill, Georgia Pacific--Toledo LLC, Cascade Pacific Pulp, 
LLC--Halsey Pulp Mill, and International Paper Company--Springfield 
Mill. As acknowledged by the NPS, ODEQ conducted FLM consultation on 
the 2023 supplement and included NPS comments in Section 6: Response to 
Federal Land Manager Review Comments.
    For the reasons stated above, it is our determination that ODEQ 
adequately conducted FLM consultation and has thus fulfilled the 
requirements of 40 CFR 51.308(i).
2. Use of the Four Statutory Factors in Determining Reasonable Progress
    Comment: ``The NPS recommends that states, including Oregon, base 
reasonable progress control determinations on the four statutory 
factors identified in Sec.  7491(g)(1) of the Clean Air Act (CAA). The 
NPS suggests that it may not be sufficient to consider the factors and 
then select a less protective control measure (or permit reduction) 
that is unrelated to the four-factor analysis. We recommend that 
determinations not clearly based on the four factors should demonstrate 
how the alternative measure is reasonable and/or equivalent to the 
outcome of the four-factor analysis.''
    Response: The EPA agrees with the NPS that reasonable progress 
control determinations must be grounded in the state's consideration of 
the four statutory factors identified in CAA section 169A and 40 CFR 
51.308(f)(2). In section IV.E.b of our proposed rulemaking, The EPA's 
Evaluation of the Oregon Long-Term Strategy, we explained how the 
Oregon process was grounded in the four-factor analysis (FFA) 
process.\4\ However, the NPS's characterization that ODEQ's January 
2021 ``Preliminary Determination of Cost Effective Controls for 
Regional Haze'' letters constituted final four-factor determinations, 
and all subsequent correspondence and action was outside the four-
factor framework is an inaccurate characterization of the Oregon 
process.\5\ The EPA will reiterate key aspects from our proposed 
rulemaking as well as details from Chapter 3.4 Four Factor Analysis of 
Oregon's April 29, 2022, regional haze plan.
---------------------------------------------------------------------------

    \4\ See 89 FR 13622 (February 23, 2024) at page 13637.
    \5\ Complete copies of the ``Preliminary Determination of Cost 
Effective Controls for Regional Haze'' letters are included in the 
docket for this action.
---------------------------------------------------------------------------

    Oregon Administrative Rules (OAR) Division 223 Regional Haze Rules 
dictated the regulatory processes for determining the controls 
necessary for reasonable progress. OAR 340-223-0110(1) required all 
affected facilities to submit four-factor analyses. The required 
contents of the four-factor analyses were specified in OAR 340-223-
0120, which mirrored the four statutory factors of CAA section 
169A(g)(1). Of the 17 facilities that submitted four-factor analyses in 
accordance with this rule, nearly all affected facilities submitted 
detailed demonstrations developed by independent consulting firms and/
or certified professional engineers asserting that no feasible or cost-
effective controls were available in applying the four-factors.\6\ Only 
2 facilities, Owens-Brockway Glass Container Inc. and Gilchrist Forest 
Products found cost effective controls under the four factors.
---------------------------------------------------------------------------

    \6\ Complete copies of the four-factor analyses are included in 
the docket for this action.
---------------------------------------------------------------------------

    Rather than simply relying on these submissions to satisfy 40 CFR 
51.308(f)(2), Oregon engaged with the affected facilities to identify 
feasible control options. Specifically, ODEQ issued ``Preliminary 
Determination of Cost Effective Controls for Regional Haze'' letters 
proposing more stringent controls unless facilities could further 
demonstrate that the measures were truly not cost effective or 
technically feasible. This initiated the process between January 2021 
and August 2021 when ODEQ assessed and determined final control 
determinations under the four factors, primarily based on the technical 
feasibility and cost correspondence documented in appendices 1-6.\7\
---------------------------------------------------------------------------

    \7\ Complete copies of appendices 1-6 were included in the 
November 2023 supplement to the regional haze plan and are also 
included in the docket for this action (document numbers 246-251).
---------------------------------------------------------------------------

    Thus, these preliminary letters did not replace the four factor 
analyses submitted by the affected facilities. Nor were the preliminary 
letters final determinations on what controls are feasible and 
necessary for reasonable progress under OAR 340-223-120(4) or 40 CFR 
51.308(f)(2). Rather, these preliminary determinations letters were a 
result of ODEQ's initial adjustment of the four-factor analyses 
submitted by the affected facilities based on

[[Page 81364]]

additional information and to aid in a consistent review across all 
four-factor analyses.\8\ Consistent with 40 CFR 51.308(f)(2) and OAR 
340-223-120(4), ODEQ determined the controls necessary for reasonable 
progress after issuing the preliminary determinations and collecting 
and analyzing additional information from the facilities regarding the 
four statutory factors. As ODEQ explained in its response to comments 
on the initial SIP submission, in some cases ODEQ agreed with 
facilities that controls it preliminarily proposed were not technically 
feasible or cost effective.\9\ Ultimately, Oregon's submission 
demonstrates that it determined the controls necessary for reasonable 
progress based on its consideration of the four statutory factors and 
thus met the requirements of 40 CFR 51.308(f)(2).

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

    Table 1 of this preamble provides a comparison of the controls 
evaluated in the four factor analyses submitted by the sources and the 
controls Oregon ultimately included in its long-term strategy. The 
exact facility-by-facility determinations are described in more detail 
in the Proposal and in subsequent responses to facility-specific 
comments in section II of this preamble.
---------------------------------------------------------------------------

    \10\ This table was created using the EPA's 2019 Guidance 
recommendation to use projected actuals or recent actuals in cost-
effectiveness calculations.
    \11\ The four-factor analysis raised technical feasibility and 
cost barriers in the determination that, ``Based on the Four Factor 
analysis presented above, no additional controls were determined to 
be cost effective for the biomass boilers at the Elgin Mill.'' See 
106_SAFOBCWoodProducts31-0006Elgin.pdf, at page 2-25. Correspondence 
related to these issues is included in 
246_3.3.2_Appendix1_Boise.Cascade.Elgin_Correspondence.pdf, included 
in the docket for this action.
    \12\ ODEQ did not pursue this control option, presumably because 
associated potential PM<INF>10</INF> emissions were low (69 tons per 
year) relative to potential NO<INF>X</INF> emissions (367 ton per 
year) and the significant difference between allowable PSEL 
emissions (Q/d = 11.92) and actual emissions (Q/d = 3.57). ODEQ 
instead proposed NO<INF>X</INF> controls in the January 2021 
preliminary determination letter. See 120_haze-EVRAZ.pdf, included 
in the docket for this action.
    \13\ The four-factor analysis argued, ``A formal engineering 
analysis would be required to ultimately determine if SNCR would be 
effective on the boilers. This type of analysis would include 
obtaining temperature and flow data, developing a model of each 
boiler using computational fluid dynamics, determining residence 
time and degree of mixing, determining placement of injectors, and 
testing.'' See 132_haze-GeorgiaPacific-Toledo-FFA.pdf, at page 2-19.
    \14\ In a letter dated September 11, 2020, Gilchrist agreed that 
installation of an Electrostatic Precipitator on boilers B-1 and B-2 
would be cost-effective, and provided a letter from a boiler vendor 
indicating that retrofitting those boilers with Selective Non-
Catalytic Reduction was not technically feasible. See April 22, 2022 
regional haze SIP at page 77.
    \15\ Catalytic ceramic filter imposed on furnace D by separate 
enforcement action. See 701_OwensBrockway2020-208MAO.pdf included in 
the docket for this action.

3. Use of Permitted Emissions Limits To Align Allowable Emissions With 
Actual Emissions
    Comment: ``We note that the Oregon SIP process allowed some 
facilities to accept permitted emission reductions to lower their 
surrogate visibility impact (emissions over distance or Q/d) to just 
below the threshold for selection rather than requiring implementation 
of cost-effective emission controls that were identified through a 
four-factor analysis . . . The NPS agrees that in cases where recent 
actual emissions would not have triggered source selection, permit 
adjustments may be an appropriate anti-backsliding measure. However, in 
cases where recent actual emissions exceed the established selection 
criteria (e.g., Kingsford Manufacturing Company and Owens-Brockway 
Glass Container Inc.), we recommend that facilities not be allowed to 
back out of selection by accepting permitted emission reductions in 
lieu of implementing cost-effective emission controls identified 
through four-factor analyses.''
    Response: The EPA agrees that in cases where recent actual 
emissions would not have triggered source selection, permit adjustments 
are an appropriate anti-backsliding measure. As demonstrated in table 4 
of our proposed rulemaking, this was the case for all facilities that 
accepted Plant Site Emission Limits (PSELs) for nitrogen oxides 
(NO<INF>X</INF>), sulfur dioxide (SO<INF>2</INF>), and/or coarse 
particulate matter (PM<INF>10</INF>), except the two cases noted by the 
NPS, Kingsford Manufacturing Company and Owens-Brockway Glass Container 
Inc.\16\ Information on Kingsford Manufacturing was included as a 
footnote to table 4, ``ODEQ reviewed Kingsford Manufacturing Company 
which originally screened into analysis with a Q/d = 8.39 based on 
actual emissions as reported to the 2017 National Emissions Inventory 
(NEI) because a 2017 PSEL was not available at that time. However, in a 
letter dated May 22, 2020, ODEQ acknowledged a 2019 permit modification 
that had already lowered PSELs for NO<INF>X</INF>, SO<INF>2</INF>, and 
PM<INF>10</INF> to a Q/d = 4.02.'' ODEQ used this 2019 information, and 
the accompanying PSEL conditions submitted in the Title V permit for 
approval into Oregon's SIP, in making its May 22, 2020, determination 
that ``that Kingsford is not required to perform a four factor analysis 
for their Springfield facility during this round of the Regional Haze 
program.'' \17\ In a case like Kingsford Manufacturing Company, where 
contemporaneous information shows a significant, permanent change in 
emissions, we believe it was reasonable for Oregon to reassess the 
agency's source selection and control determination to incorporate more 
recent information.
---------------------------------------------------------------------------

    \16\ See 89 FR 13622 (February 23, 2024) at page 13639.
    \17\ See 142_haze-KingsfordManufCo.pdf in the docket for this 
action.
---------------------------------------------------------------------------

    Similarly, ODEQ's evaluation of control for the Owens-Brockway 
facility was influenced by contemporaneous events. Owens-Brockway was 
one of the few facilities that identified feasible cost-effective 
controls in the four-factor analysis process.\18\ As noted by the 
commenter, in an October 27, 2020, letter ODEQ concurred with the 
findings that combined control of NO<INF>X</INF>, SO<INF>2</INF> and PM 
by catalytic ceramic filters (CCF) was cost-feasible for glass-melting 
furnaces A and D at the Owens-Brockway Portland facility.\19\ 
Subsequently, in June 2021, ODEQ initiated an enforcement response for 
air quality violations unrelated to the regional haze program.\20\ The 
enforcement response was still in progress during the summer of 2021, 
therefore ODEQ could not rely on the remedy being negotiated to resolve 
the human health violations (shutdown or imposition of pollution 
controls on Furnaces D).\21\ Instead, ODEQ negotiated and submitted a 
separate August 9, 2021, order focused specifically on reasonable 
progress for regional haze program.\22\ This order enshrined the 
shutdown of Furnace A and associated emissions reductions.

action.
---------------------------------------------------------------------------

    The EPA disagrees with the commenter that the Regional Haze Rule 
prohibits a state which selects sources based on allowable emissions 
from refining its source selection based on permanent and enforceable 
reductions in allowable emissions. ODEQ determined that sources with a 
Q/d <5 based on PSELs are not significant contributors to visibility 
impairment in Class I areas. Hence, controls on these sources are not 
necessary for reasonable progress. This holds true regardless of when 
in its SIP development process ODEQ made the determination. Most 
importantly, ODEQ ensured the PSEL reductions upon which it relied to 
determine that controls on Owen-Brockway were not necessary and were 
permanent and enforceable by submitting a source-specific SAFO and 
conditions from Owens-Brockway's title V permit.
4. Use of a Stipulated Agreement and Final Order (SAFO) Versus a 
Unilateral Order
    Comment: ``. . . Oregon proposed alternative compliance options for 
several facilities in lieu of reasonable, cost-effective controls 
identified through the four-factor review process. In general, the NPS 
has concerns with this approach and previously shared this view with 
Oregon in staff-to-staff meetings between 2020 and 2023, and in writing 
via October 2021 public comments on the draft SIP and August 2023 
consultation comments on the Oregon SIP supplement . . . The NPS also 
agrees that alternative compliance measures can be considered 
reasonable when accompanied by a technical demonstration that the 
emission reductions achieved will be equivalent to or better than those 
that would have resulted from requiring the controls identified through 
four-factor analysis. The NPS recommends that EPA require a technical 
demonstration detailing the actual emission reductions that will be 
achieved through alternative compliance and why the alternative 
compliance options are reasonable in light of the four statutory 
factors.''
    Response: The EPA disagrees that additional technical 
demonstrations are required to justify ODEQ's determinations of the 
controls necessary for reasonable progress. As explained in our 
response to comment in section II.A.2 ``Use of the Four Statutory 
Factors in Determining Reasonable Progress'' of this preamble, 
characterizing the January 2021 ``Preliminary Determination of Cost 
Effective Controls for Regional Haze'' letters as final four-factor 
control determinations and all subsequent correspondence and decisions 
after the preliminary letters as being outside the four-factor process 
is not an accurate portrayal of the Oregon process. Under OAR 340-223-
0110(1), each affected facility was required to conduct a four-factor 
analysis compliant with OAR 340-223-0120 Four Factor Analysis. Using 
its authority under OAR 340-223-0120(3), ODEQ adjusted the four-factor 
analyses for consistency with basic inputs such as interest rates, 
equipment lifetime, and potential to emit (PSEL) in determining the 
proposed cost-effective controls.\23\ However, it is clear from the 
text that the January 2021 preliminary letters are not final 
determinations nor

[[Page 81366]]

independent four-factor analyses in themselves, ``Based on the 
information provided in the four factor analysis, the cost information 
that you submitted, the additional information you provided, and the 
process DEQ is proposing to use to screen facilities, DEQ estimates the 
following controls are likely to be required at your facility . . . If 
you disagree with or would like to discuss DEQ's preliminary 
determination as outlined in this letter, we encourage you to reach out 
to the DEQ now.'' \24\
---------------------------------------------------------------------------

    \23\ See 89 FR 13622 (February 23, 2024) at page 13641.
    \24\ See 108_haze-BosieCascade-Medford.pdf.
---------------------------------------------------------------------------

    Under OAR 340-223-0110(1), if a source accepted ODEQ's preliminary 
determination, ODEQ could finalize the determinations in a unilateral 
order under OAR 340-223-0130, SAFO under OAR 340-223-0110(2)(b)(B), or 
other enforceable mechanism such as a permit modification.\25\ However, 
since nearly all the affected facilities asserted no feasible cost-
effective controls in the four-factor analyses, this initiated a 
process from January 2021 to August 2021 to review additional 
information regarding the technological feasibility and cost of 
controls pursuant to OAR 340-223-0120(2), to determine the controls 
necessary to select sources and for reasonable progress, and impose 
these controls either through a unilateral order or SAFO.
---------------------------------------------------------------------------

    \25\ See 
136_GilchristNoticeofApplicationforESPinstall20210608.pdf.
---------------------------------------------------------------------------

    Each of the compliance options in OAR 340-223-0110(2) are either 
part of Oregon's source selection methodology or grounded in the four-
factor analysis required by OAR 340-223-0110(1) and 0120. We do not 
interpret OAR 340-223-0110(2) as permitting alternatives to the 
requirements of the CAA or Regional Haze Rule. Rather, entering into a 
SAFO (agreed order) is an alternative administrative mechanism to 
impose controls necessary for reasonable progress that would have been 
contained in a unilateral order.
    Our review of Oregon's Regional Haze SIP submission indicates that 
ODEQ continued to consider the four factors in its engagement with each 
of the sources after issuance of the preliminary determination letters. 
This is documented in appendices 1 through 6 of Oregon's November 22, 
2023, SIP supplement.\26\ After considering the additional information 
regarding technological feasibility, cost of controls, energy and non-
air quality impacts, and time necessary to impose the controls, ODEQ 
determined the appropriate administrative mechanism to impose the 
enforceable emission limitations. In most cases the most efficient and 
effective mechanism was a SAFO issued under OAR 340-223-0120(2).
---------------------------------------------------------------------------

    \26\ See documents 246 through 251b included in the docket.
---------------------------------------------------------------------------

    Based on our review of the administrative record, the EPA does not 
believe that the differences between the January 2021 preliminary 
control determinations and the final four-factor control determinations 
in the August 2021 SAFOs are a function of the enforceable mechanism 
used (a unilateral order under OAR 340-223-0130 versus a SAFO issued 
under OAR 340-223-0110(2)). Instead, as discussed in our facility-
specific responses to comment, the differences appear to be a result of 
ODEQ's consideration of technical feasibility and cost as documented in 
appendices 1-6 of the November 2023 supplement. Given that these SAFOs 
are outgrowths of ODEQ consideration of the four factors, rather than 
other factors, we disagree that additional evaluation is necessary.
5. Compliance Deadlines
    Comment: ``In the 2023 SIP supplement, Oregon extended the 
compliance deadlines for emission unit replacements (associated with 
alternative compliance) from July 31, 2026, to July 31, 2031. This 
extended deadline is well beyond the end of the current regional haze 
planning period and will allow current emissions from affected 
facilities to continue without mitigation for an additional five years. 
In their 2019 regional haze guidance document, the EPA states that the 
reasonable progress goals ``for the second implementation period are to 
be based only on the combined effect of the LTS measures with 
compliance dates on or before December 31, 2028.''
    Response: The citation to the EPA's 2019 Guidance provided by the 
commenter deals with modeling, and notes that states cannot claim 
projected 2028 emissions reductions in the modeling if those control 
measures are not in effect by 2028.\27\ This is not a regulatory 
prohibition on controls outside the implementation period. The relevant 
regulatory citation is 40 CFR 51.308(f)(2)(i), which requires that if a 
state concludes that a control measure cannot reasonably be installed 
and become operational until after the end of the implementation 
period, the state may not consider this fact in determining whether the 
measure is necessary to make reasonable progress. The clear implication 
is that controls after the end of the implementation period are 
allowable under the RHR if the determinations are reasonable. An 
example is Oregon's regional haze plan for the first implementation 
period which adopted regulatory provisions to cease coal-fired 
electricity generation at the Boardman facility, however implementation 
of the measures (closure of the coal-fired operations) would not occur 
until the second planning period, in 2020.\28\ Another example is 
Washington's regional haze plan for the first implementation period 
which required closure of the coal-fired units at the TransAlta 
facility, however closure of units was phased in 2020 and 2025, during 
the second implementation period.\29\
---------------------------------------------------------------------------

    \27\ See 2019 Guidance, at page 46, Regional scale modeling of 
the LTS to set the RPGs for 2028.
    \28\ See 77 FR 50611 (August 22, 2012).
    \29\ See 79 FR 33438 (June 11, 2014).
---------------------------------------------------------------------------

    With respect to Oregon's determinations under the four factors, 
some pollution controls were imposed under 340-223-0110(2)(b)(B) and 
(C), which required installation of identified controls no later than 
July 31, 2026. For a subset of units, ODEQ used authority under OAR 
340-223-0110(2)(b)(E), which allowed replacement of an emissions unit 
by no later than July 31, 2031. The comment, ``[i]n the 2023 SIP 
supplement, Oregon extended the compliance deadlines for emission unit 
replacements (associated with alternative compliance) from July 31, 
2026 to July 31, 2031'' is a misreading of the Oregon regional haze 
rules. The July 31, 2026, compliance deadlines under OAR 340-223-
0110(2)(b)(B) and (C) apply to retrofit options. Instead, ODEQ followed 
the compliance deadline in OAR 340-223-0110(2)(b)(E) which applies to 
emissions unit replacement. These regulatory provisions were adopted by 
the Oregon Environmental Quality Commission after a full public comment 
period from May 28, 2021, to June 30, 2021, and a hearing conducted on 
June 28, 2021.\30\
---------------------------------------------------------------------------

    \30\ See 702_staff report EQC 
meeting_072321_ItemJ_RegionalHaze.pdf.
---------------------------------------------------------------------------

    We also believe that the comment, ``[i]n the 2023 SIP supplement, 
Oregon extended the compliance deadlines for emission unit replacements 
(associated with alternative compliance) from July 31, 2026 to July 31, 
2031'' is a misreading of the record. An example is the Northwest 
Pipeline Baker City facility. The original SAFO, effective August 9, 
2021, did not include a concrete deadline for emissions unit 
replacement.\31\ In response to EPA comment, as indicated in the 
amended SAFO, ``DEQ received comments from the U.S. Environmental 
Protection Agency on the Regional Haze State

[[Page 81367]]

Implementation Plan, requiring amendments to the SAFO,'' ODEQ added a 
concrete compliance deadline for unit replacement and submitted the 
amended SAFO as part of the 2023 supplement.\32\ In our review of the 
record we see no evidence to suggest ODEQ modified compliance deadlines 
without a clear basis under the four factors.

A1_SAFO.pdf, included in the docket for this action.
---------------------------------------------------------------------------

    Lastly, with respect to ODEQ's application of OAR 340-223-
0110(2)(b)(E), this must be viewed in the context of the overall mix of 
timelines (most before 2028) and the other controls imposed (primarily 
by July 31, 2026). ODEQ evaluated 43 emissions units and a total of 62 
control devices.\33\ Of this universe, ODEQ determined that unit 
replacement may be a reasonable control option for 10 units. Given the 
complexity and logistical challenges of complete emissions unit 
replacement, we believe ODEQ's selective use of the full compliance 
deadline allowable under OAR 340-223-0110(2)(b)(E) is reasonable under 
the four factors of CAA section 169A(g)(1) and 40 CFR 51.308(f)(2), 
including the time necessary for compliance.

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

6. Standards for Emissions Unit Replacement
    Comment: ``New emission units generally have lower emissions than 
older units. However, a wide variety of emissions are possible from new 
units. In several places, the Oregon SIP requires that new units 
``shall meet the most recent permitting standards and requirements for 
new emission units (including but not limited to New Source Performance 
Standards) in place at the time of submitting a permit application.'' 
As the NPS shared with ODEQ during SIP supplement consultation, this 
may not be adequately protective because new source performance 
standards (NSPS) are frequently less stringent than best available 
control technology (BACT)-level controls or those that may be deemed 
reasonable through a four-factor analysis.''
    Response: As a fundamental matter, the EPA disagrees that best 
available control technology (BACT) is an appropriate threshold for 
evaluating Oregon's determinations of the controls necessary for 
reasonable progress for the second planning period. For a source 
recently permitted to BACT standards, it may be reasonable for the 
state to argue that these controls are equivalent to or more stringent 
than controls that would be derived under the regional haze four-factor 
process.\34\ However, the inverse is not true. It is not the EPA's 
expectation that controls derived under the regional haze four-factor 
process necessarily meet the stringency level of BACT.
---------------------------------------------------------------------------

    \34\ See 2019 Guidance, at page 22-23.
---------------------------------------------------------------------------

    With respect to the comment that Oregon's control determinations 
may not be adequately protective because new source performance 
standards (NSPS) are frequently less stringent than those that may be 
deemed reasonable through a four-factor analysis, we disagree. Many of 
the existing units that Oregon reviewed emit significantly more 
NO<INF>X</INF>, carbon monoxide, and volatile organic compounds than 
new units meeting the emission limits in 40 CFR part 60, subpart 
Subpart JJJJ--Standards of Performance for Stationary Spark Ignition 
Internal Combustion Engines.\35\ Thus, replacement of these existing 
units with new units meeting the NSPS will result in substantial 
emissions reductions. Therefore, we disagree that these standards are 
not adequately protective.
---------------------------------------------------------------------------

    \35\ Most recently updated August 10, 2022 (87 FR 48606).
---------------------------------------------------------------------------

    Finally, under OAR 340-223-0110(1) all affected facilities 
submitted four-factor analyses. These analyses were conducted by 
independent consultants and/or certified professional engineers on 
behalf of the sources. In all instances that ultimately resulted in 
unit replacement, these independent consultants and/or certified 
professional engineers provided four-factor demonstrations that there 
were ``no feasible cost-effective'' controls. Rather than accepting 
these ``no feasible cost-effective'' control demonstrations pro forma, 
ODEQ used its authority under OAR 340-223-0110(2)(b)(E) to compel 
significant future reductions (emission unit replacement) beyond the 
initial four-factor analyses. The example of Northwest Pipeline, Baker 
City is illustrative. This facility has three natural gas-fired 
reciprocating engines dating from 1956 (EU1) and one engine dating from 
1981 (EU2). The four-factor analysis asserted the only feasible 
technology was low emission combustion retrofit with calculated cost-
effectiveness of $25,850 for EU1 and $24,243 for EU2. Considering the 
significant emissions reductions from replacing these old engines, we 
believe this is a reasonable approach to considering the four statutory 
factors in determining the controls necessary for reasonable progress.
7. Wauna Facility--Biomass-Fired Fluidized Bed Boiler
    Comment: ``The Georgia Pacific--Wauna Mill and Roseburg Forest 
Products--Dillard have the highest cumulative impact on NPS Class I 
areas. The NPS is generally satisfied with the outcome of the control 
determinations for these facilities. However, we note that ODEQ has not 
addressed the NPS recommendation to evaluate addition of low 
NO<INF>X</INF> burners and flue gas recirculation to reduce 
NO<INF>X</INF> emissions from the Georgia Pacific--Wauna Mill biomass-
fired fluidized bed boiler which could further reduce haze-causing 
emissions from that facility.''
    Response: The EPA reviewed Oregon's April 2022 and November 2023 
submissions and associated documents. We found citations related to the 
biomass-fired fluidized bed boiler at the Wauna facility. However, we 
found no record of a prior comment by the NPS directly related to the 
``NPS recommendation to evaluate addition of low NO<INF>X</INF> burners 
and flue gas recirculation to reduce NO<INF>X</INF> emissions from the 
Georgia Pacific--Wauna Mill biomass-fired fluidized bed boiler.'' Below 
is a summary of the administrative record reviewed by the EPA.
    On June 15, 2020, Georgia-Pacific submitted a four-factor analysis 
that stated, ``LNB [low NO<INF>X</INF> burners] are not feasible for GP 
Wauna's Fluidized Bed Boiler. The natural gas burners are only for 
auxiliary use and do not drive NO<INF>X</INF> emissions from the unit. 
The boiler already employs SNCR to reduce NO<INF>X</INF> emissions from 
the bubbling fluidized bed.'' \36\ As part of the May 2021 FLM 
consultation draft process, the NPS comments focused entirely on 
selective catalytic reduction (SCR) cost calculations for this unit and 
made no mention of LNB.\37\ In its October 29, 2021, comments NPS did 
state, ``We recommend that ODEQ's draft SIP more thoroughly address 
emissions from GP Wauna by including an analysis of emissions from the 
Fluidized Bed Boiler.'' \38\ However, the contents of the comments 
again focused exclusively on SCR costs, with no specific mention of LNB 
at this unit. Additional comments submitted on August 29, 2023, as part 
of the FLM consultation process for the November 2023 regional haze

LNB at this specific unit.\39\ In the absence of more concrete 
information, we believe it was reasonable for ODEQ to rely on the 
determination in the four-factor analysis that LNB was not feasible for 
the Fluidized Bed Boiler (FBB) because ``natural gas burners are only 
for auxiliary use and do not drive NO<INF>X</INF> emissions from the 
unit'' \40\ and was, therefore, not put forward by ODEQ as a potential 
control measure in the January 2021 ``Preliminary Determination of Cost 
Effective Controls for Regional Haze'' letter for this facility.\41\ 
The comment does not present information that clearly refutes the 
determination in the four-factor analysis that LNB/FGR is not feasible 
for the FBB at the Wauna Mill.

    Comment: ``We believe that selective catalytic reduction (SCR)

    Georgia-Pacific's June 2020 four-factor analysis indicates that SCR 
may be cost-effective for the No. 1 Boiler when calculated using 
permitted allowable emissions (PSELs) under ODEQ's methodology.\43\ 
However, as described in Section 5 of the November 2023 regional haze 
supplement, Oregon found Georgia-Pacific's April 30, 2021, follow-up 
four-factor analysis correspondence compelling with respect to both 
cost of compliance and energy and nonair quality environmental impacts 
of compliance.\44\ Therefore, Oregon issued its final control 
determination to require LNB/FGR or unit replacement for all three 
boilers under order number 21-0005, amendment A1.\45\

    We believe that it was reasonable for ODEQ to appropriately weigh 
the ``energy and nonair quality environmental impacts of compliance'' 
as well as the cost of compliance considerations raised in the April 
30, 2021, four-factor correspondence when determining the controls 
necessary for reasonable progress.
9. Georgia-Pacific--Toledo LLC--Emission Limit
    Comment: ``[I]t is unclear how the emission limit associated with 
compliance option 1 was derived. We suggest that a four-factor analysis 
or technical demonstration justifying the 0.09 lb/MMBtu emission limit 
for NO<INF>X</INF> associated with the proposed control option would 
improve the SIP.''
    Response: The emissions limit associated with compliance option 1 
was discussed in the April 30, 2021, four-factor analysis 
correspondence, included in Appendix 4 of ODEQ's 2023 supplement.\46\ 
As stated in the April 30, 2021 letter, this limit was based on Georgia 
Pacific's internal engineering experience and discussions with outside 
vendors. In our review of the four-factor analysis, the 0.09 lb/MMBtu 
emission limit for NO<INF>X</INF> represents a 68% reduction for boiler 
1, a 45% reduction for boiler 3, and a 68% reduction for boiler 4.\47\ 
These reductions are generally comparable to the estimated emissions 
reductions in the four-factor analyses (79% for boiler 1, 47% for 
boiler 3, and 53% for boiler 4) which were calculated on a tons per 
year basis.\48\ As calculated in our supporting memo included in the 
docket for this action, the 0.09 lb/MMBtu emission limit for 
NO<INF>X</INF> is comparable and slightly more stringent than the EPA's 
emissions factors contained in AP-42: Compilation of Air Emissions 
Factors from Stationary Sources for large wall-fired boilers controlled 
with flue gas recirculation.\49\ Therefore, we believe ODEQ's selection 
of the final emissions limit is adequately justified, documented, and 
an acceptable means of refining the estimated emission rate contained 
in the four-factor analysis for the purposes of characterizing the cost 
of compliance.\50\

10. Georgia-Pacific--Toledo LLC Emissions--Unit Replacement
    Comment: ``Nevertheless, the NPS supports compliance option 1. 
Installation of low NO<INF>X</INF> burners and flue gas recirculation 
will secure a 64% NO<INF>X</INF> reduction from Georgia-Pacific--Toledo 
LLC during the second implementation period (2018-2028). In contrast, 
compliance option 2 would defer

[[Page 81369]]

emission reductions for an additional five years, beyond the end of the 
planning period.''
    Response: In the April 30, 2021, response letter to ODEQ, Georgia-
Pacific stated, ``The GP Toledo Mill has three affected power boilers 
(Nos. 1, 3, and 4 Power Boilers) and needs flexibility in determining 
if burners will be replaced in each unit or whether one or two new 
boilers will be constructed to replace these three units . . . Steam 
supply is a significant operational consideration for any pulp and 
paper manufacturing facility. Each GP mill requires steam in the pulp 
production process as well as the papermaking process. As such, changes 
to steam producing assets require substantial consideration of and 
planning for the assets themselves as well as the entire pulp and paper 
manufacturing process to minimize disruptions to overall mill 
operations. Both mills will need sufficient time to plan the boiler 
projects with both internal and external engineering resources, and 
then implement the changes with as little interruption to mill 
operations as possible. Therefore, GP is requesting an extended 
timeframe for implementation of these boiler projects.'' As noted in 
the 2023 supplement to the regional haze plan, ODEQ considered this 
correspondence in determining under CAA section 169A(g)(1) and 40 CFR 
51.308(f)(2) ``the time necessary for compliance'' that a deadline of 
July 31, 2031, was appropriate should complete emission unit 
replacement be necessary.\51\

    The EPA has reviewed SAFO 21-0005, the subsequent amendment 
effective December 5, 2022, and the associated four-factor analysis. 
Based on the four-factor analysis, installing LNB and flue gas 
recirculation based on 2017 actual emissions had cost effectiveness 
figures of EU 11 = $10,042, EU 13 = $7,083, and EU18 = $21,024.\52\ 
Considering that for two of the boilers the cost effectiveness figure 
exceed $10,000/ton, we believe it was reasonable for ODEQ to provide 
flexibility on a unit-by-unit basis in providing the two compliance 
options: (1) full unit replacement by 2031; or (2) installation of LNB 
with flue gas recirculation by 2026.

11. Cascade Pacific Pulp, LLC--Halsey Pulp Mill Power Boilers--SCR
    Comment: ``The Oregon SIP requires this facility to eliminate use 
of no. 6 fuel oil by June 30, 2024, replace power boiler #2 with a new 
emissions unit that will achieve a limit of 0.036 lbs NO<INF>X</INF>/
MMBtu as a 30-day rolling average no later than July 31, 2031, and, 
upon replacement of power boiler #2, limit emissions from power boiler 
#1 to no more than 27 tons of NO<INF>X</INF> per year . . . SCR may 
still be a feasible and more rigorous NO<INF>X</INF> emission control 
option for the power boiler #1 than the control determination requires. 
In its Good Neighbor Plan, EPA recently determined that SCR is 
technically feasible to control NOx emissions from natural gas-fired 
industrial boilers at pulp and paper mills.''
    Response: On June 15, 2020, Cascade Pacific Pulp, LLC submitted a 
four-factor analysis prepared by the environmental consulting service 
ALL4 Inc.\53\ With respect to SCR, ALL4 calculated the cost 
effectiveness of SCR ($/ton NO<INF>X</INF> reduced) on CPP Halsey power 
boiler #1 to be $16,029 based on 2017 PSEL and $38,292 based on 2017 
actual emissions. ALL4 calculated the cost effectiveness for CPP Halsey 
power boiler #2 to be $28,349 based on 2017 PSEL and $204,083 based on 
2017 actual emissions.\54\ Using its authority under OAR 340-223-
0120(3), ODEQ preliminarily adjusted the four-factor analyses using 
conservative inputs such as interest rate (3.25%), equipment lifetime 
(30 years), and potential to emit (PSEL). However, after these 
adjustments, ODEQ did not find SCR cost-effective at the $10,000 
threshold as evidenced by the agency's determination to propose LNB 
with flue gas recirculation instead of SCR for power boiler #1 as part 
of the ``Preliminary Determination of Cost Effective Controls'' 
letter.\55\

    In our 2019 guidance, we recommend the use of recent actuals or

calculating cost-effectiveness.\56\ Considering the SCR cost 
effectiveness at these units based on the recent actual emissions 
contained in the four-factor analysis ($38,292 for power boiler #1 and 
$204,083 for power boiler #2), we have no reasonable basis to dispute 
Oregon's determination that SCR was not cost effective for these units.

12. Cascade Pacific Pulp, LLC--Halsey Pulp Mill Power Boilers--LNB
    Comment: ``It is unclear how the future emission limit associated 
with the replacement of power boiler #2 was derived. We believe that a 
four-factor analysis or technical demonstration justifying the 0.036 
lbs NO<INF>X</INF>/MMBtu emission limit would improve the SIP.''
    Response: The EPA acknowledges that ODEQ's decision-making for the 
August 25, 2023, final control determination under SAFO 22-3501-A2 
could have been clearer in the SIP submissions. However, ODEQ's SIP 
submissions ultimately meet the requirement in 40 CFR 51.308(f)(2)(iii) 
to document the technical basis, including modeling, monitoring, cost, 
engineering, and emissions information, on which the state relied to 
determine the emission reduction measures that are necessary for 
reasonable progress. With respect to Cascade Pacific Pulp, LLC--Halsey 
Pulp Mill Power Boilers, ODEQ's November 2023 regional haze supplement 
documents ODEQ's process for its reasonable progress determination.\57\ 
The 2023 supplement states that, on January 21, 2021, ODEQ proposed 
that LNB with flue gas recirculation on power boiler #1 could be cost 
effective and included this control as part of the ``Preliminary 
Determination of Cost Effective Controls'' letter.\58\ On January 27, 
2021, Cascade Pacific Pulp responded by questioning ODEQ's cost 
analysis and submitting a revised cost analysis performed by ALL4 
consulting service for power boiler #1.\59\ On August 9, 2021, Cascade 
Pacific Pulp and ODEQ entered into SAFO 22-3501, establishing 
installation of a LNB on power boiler #1.\60\ On February 1, 2022, the 
parties agreed to amend the order to allow the option of unit 
replacement for power boiler #1.\61\ On August 25, 2023, the parties 
again amended the order to allow the unit replacement of power boiler 
#2 instead of power boiler #1.\62\

    While ODEQ's documentation could have been more robust, the 
commenter does not provide information to indicate that ODEQ's 
determination was unreasonable or inadequate. ODEQ's January 21, 2021, 
preliminary control determination and subsequent SAFO

[[Page 81370]]

modifications are direct outgrowths of ODEQ's review of and action upon 
the June 15, 2020, four-factor analysis. This four-factor analysis (as 
revised on January 27, 2021) asserted that LNB with flue gas 
recirculation was not cost-effective for power boiler #1 ($10,559 per 
ton reduced based on PSEL and $26,446 per ton reduced based on 2017 
actual emissions).\63\ To the extent that LNB with flue gas 
recirculation (as proposed in ODEQ's preliminary determination) may be 
above Oregon's $10,000 per ton cost effectiveness threshold, as 
asserted by the ALL4 analysis, or may be below Oregon's $10,000 per ton 
threshold with a different assumption set, the EPA does not see a 
compelling basis to dispute ODEQ's final control determination.
---------------------------------------------------------------------------

    \63\ See 
248_3.3.2_Appendix3_Cascade.Pacific.Pulp_.Halsey_Correspondence.pdf, 
at page 581 of the pdf.
---------------------------------------------------------------------------

    First, it is clear from our review of the administrative record 
that ODEQ conducted a multi-year, extensive effort to evaluate control 
options under the four statutory factors of CAA section 169A(g)(1).\64\ 
Second, Oregon's $10,000 per ton cost effectiveness threshold is one of 
the highest in the nation, if not the highest, applied specifically 
under the regional haze program. If the EPA were to conduct its own 
independent cost analysis, the EPA would not necessarily use a $10,000 
threshold for determining reasonable progress controls. Third, ODEQ 
chose a more stringent methodology than the EPA's 2019 guidance 
recommends in calculating cost effectiveness using allowable emissions 
(PSELs). Use of recent actuals or projected actuals in accordance with 
the 2019 guidance \65\ would almost certainly result in a less 
stringent outcome than ODEQ's methodology. Lastly, as noted in a 
previous response to comment, Oregon engaged in a rigorous process to 
improve the accuracy of the facility submitted four-factor analyses, 
rather than accepting the initial conclusions pro forma. In the case of 
Cascade Pacific Pulp Halsey, Oregon's process resulted in significant 
future emissions reductions (unit replacement) well beyond the four-
factor analysis submitted pursuant to OAR 340-223-0110(1) which 
concluded there were no feasible cost-effective controls. More details 
on the 0.036 lbs NO<INF>X</INF>/MMBtu emission limit imposed by ODEQ 
are discussed in section II.A.13 of this preamble.

13. Cascade Pacific Pulp, LLC--Halsey Pulp Mill Power Boilers--
Compliance Deadline and Emission Limit
    Comment: ``The NPS supports the elimination of #6 fuel oil. 
However, replacing power boiler #2 on the identified schedule and 
requiring emission reductions from power boiler #1 following power 
boiler #2's replacement will defer emission reductions beyond the end 
of the planning period (see above for additional discussion).''
    Response: In a discussion with the EPA, ODEQ explained how the 
agency's perspective regarding emissions unit replacement evolved 
through the four-factor analysis process.\66\ ODEQ found that new, 
purpose-built units with controls like LNB built in offered superior 
emissions reductions compared to the limitations of retrofitting an 
older unit. For units like the Halsey power boilers built in 1968, this 
was particularly notable. ODEQ weighed the superior emissions 
reductions of emissions unit replacement against the additional time 
necessary for compliance (2031 for unit replacement versus 2023 for 
retrofit in the original SAFO) and determined that this was a 
reasonable trade-off in considering the significantly improved 
emissions reductions.
---------------------------------------------------------------------------

    \66\ See 712_CPP Halsey_supporting memo.pdf, included in the 
docket for this action.
---------------------------------------------------------------------------

    The EPA reviewed the four-factor analysis \67\ and the emissions 
reductions expected to result from the LNB/FGR retrofit of power boiler 
#1 as required in SAFO 22-3501 as well as the emissions reductions 
resulting from replacement of power boiler #2 as required in SAFO 22-
3501-A2. As described in our supporting memo to the docket, and based 
on our calculations, the LNB/FGR retrofit of power boiler #1 could 
potentially be expected to result in a reduction in NO<INF>X</INF> 
emissions of 0.07 lb/MMBtu, while complete emission unit replacement of 
power boiler #2 as the primary steam production will result in a 
reduction in NO<INF>X</INF> emissions of between 0.145-0.185 lb/MMBtu. 
Replacement of power boiler #2 will therefore result in significantly 
more reductions in NO<INF>X</INF> emissions than LNB/FGR retrofit of 
power boiler #1. Therefore, the EPA believes this is a credible 
rationale and indicates that the state appropriately considered the 
four factors in determining the controls necessary for reasonable 
progress.

14. International Paper--Springfield--Emission Limit
    Comment: ``According to the four-factor analysis provided in the 
Oregon SIP, the recent actual emission rate achieved by the 
International Paper--Springfield power boiler is 0.22 lb 
NO<INF>X</INF>/MMBtu. Therefore, this control determination, requiring 
an emission limit of 0.25 lb NO<INF>X</INF>/MMBtu, may allow an 
increase in emissions from the primary emission unit at the facility. 
The Good Neighbor Plan limits NO<INF>X</INF> emissions from natural 
gas-fired boilers like the power boiler to 0.08 lb/mmBtu. The NPS 
recommends that EPA and ODEQ set a NO<INF>X</INF> emission limit 
consistent with the Good Neighbor Plan. The current control 
determination for this facility lowers the allowable permitted 
emissions but will not actually reduce haze-causing emissions.''
    Response: The EPA disagrees. The estimated recent actual emission 
rate is not directly comparable to the prescribed emission limit. The 
0.22 lb NO<INF>X</INF>/MMBtu emission rate cited by the commenter is 
described in Appendix 6 of Oregon's November 2023 supplement, ``All 
emissions used in the 4FA Report for 2017 were previously reported in 
the 2017 Annual report to Lane Regional Air Protection Agency (LRAPA) 
with one notable exception. The Power Boiler NO<INF>X</INF> emissions 
for the 4FA Report were determined by the Continuous Parameter 
Monitoring System Formula per Title V, permit condition 186.g. The 
NO<INF>X</INF> reported in the Annual report was based upon the maximum 
emission factor of 0.46 lb/MMBtu. The weighted average emission factor 
determined from the Continuous Parameter Monitoring System Formula is 
0.2195 lb/MMBtu which was used to determine the actual NO<INF>X</INF> 
tons for 2017 from the Power Boiler.'' \68\
---------------------------------------------------------------------------

    \68\ See 
251b_Appendix6_InternationalPaper.SpringfieldMill_Correspondence.pdf,
 at page 4 of the PDF.
---------------------------------------------------------------------------

    The EPA notes that the 0.2195 lb/MMBtu figure used in the 2017 
Annual report is an annual average emission factor whereas the 0.25 lb 
NO<INF>X</INF>/MMbtu emission limit is based on a 7-day rolling 
average.\69\ Thus, ODEQ was reasonable in considering the emission rate 
the Power Boiler could achieve averaged over a rolling 7-day period 
rather than an annual period. Moreover, there are numerous variables 
and assumptions inherent in the formula used in the prior Title V 
permit to

[[Page 81371]]

derive the emissions factor. In particular, Condition 186.g of the 
prior Title V permit included two emission factor formulas: one for 
natural gas flow rate less than or equal to 380MSCF/Hr and one for 
greater than 380MSCF/Hr. Each of these formulas contains a fixed 
multiplier and fixed correction factor. Any variation in each of these 
variables would yield a different emission rate. ODEQ was reasonable in 
taking these circumstances into consideration when setting the emission 
rate the company must achieve on a 7-day average basis. The EPA 
disagrees with the assertion that this short-term emission limit will 
lead to long-term emissions increases compared to recent actuals. 
Moreover, ODEQ is requiring CEMS--a reliable method of monitoring and 
recording emissions data.\70\ This data will assure compliance with the 
emission rate and also inform later planning periods.
---------------------------------------------------------------------------

    \69\ See 139_SAFODEQ-LRAPA-IP.pdf.
    \70\ Id.
---------------------------------------------------------------------------

    With respect to the comments that ODEQ's reasonable progress 
determination will not reduce emissions, we note that reasonable 
progress has two prongs: the prevention of any future anthropogenic 
visibility impairment and the remedying of any existing anthropogenic 
visibility impairment.\71\ The commenter is assuming that recent 
actuals are necessarily determinative of projected future actuals 
through 2028. This is not necessarily the case. Without lower PSELs, 
Springfield could ramp up production and emissions. Thus, ODEQ decision 
to lower PSELs to align with recent actuals is consistent with the 
Regional Haze Rule and CAA.
---------------------------------------------------------------------------

    \71\ Clarifications Regarding Regional Haze State Implementation 
Plans for the Second Implementation Period, July 8, 2021, at page 8.
---------------------------------------------------------------------------

    Setting aside this meaningful difference in the monitoring and 
compliance method, the process ODEQ used to determine the controls 
necessary for reasonable progress for International Paper underscores 
the ODEQ's reasonableness. Importantly, ODEQ calculated cost thresholds 
based on allowable emissions (PSELs) versus recent actual emissions 
(2017). This decision was a driving force behind ODEQ's preliminary 
control determinations and enabled the state to adjust the initial 
four-factor analyses to ultimately determine the controls necessary for 
reasonable progress.
    As noted in our response to comment in section II.A.11 Cascade 
Pacific Pulp, LLC--Halsey Pulp Mill Power Boilers--SCR of this 
preamble, Oregon's decision to calculate cost thresholds based on 
allowable emissions was much more stringent than the EPA's 
recommendation in the 2019 guidance.\72\ For a facility like 
International Paper, the difference between 2017 actuals (724 tons per 
year NO<INF>X</INF>) \73\ and allowable PSEL emissions (1692 tons per 
year NO<INF>X</INF>) \74\ resulted in dramatic differences in the cost 
effectiveness of control calculations ($ per ton of NO<INF>X</INF> 
reduced) as shown in table 3 of this preamble. On January 21, 2021, 
ODEQ used PSEL cost effectiveness of controls to propose SCR for the 
power boiler in the agency's ``Preliminary Determination of Cost 
Effective Controls'' letter.\75\ On February 2, 2021, International 
Paper objected to ODEQ using allowable PSEL emissions in determining 
the cost effectiveness of controls.\76\ International Paper also raised 
this issue in its September 18, 2020, letter to ODEQ stating, ``In 
addition, we are concerned by DEQ's misdirected focus on reducing Plant 
Site Emission Limits (PSEL) rather than focusing upon the impact to 
visibility impairment of actual emissions. Focusing on PSEL in the 
evaluation of cost effectiveness for controls compounds the inequity of 
DEQ's approach to this process compared to other Western States. The 
Springfield Mill's cost effectiveness for actual emission reduction is 
well above the previously discussed threshold of $10,000/ton for all of 
the pollution control units listed by DEQ.'' \77\

    International Paper then provided a March 15, 2021, memorandum from 
the ALL4 environmental consulting firm providing updated costs of 
controls, mirroring the parameters used in ODEQ's preliminary control 
determination (3.25% interest rate and 30-year equipment life).\78\ In 
the same memorandum, ALL4 recommended that International Paper request 
a 179 ton per year NO<INF>X</INF> PSEL and 0.25 lb NO<INF>X</INF>/MMBtu 
emissions limit for the power boiler so that the calculation of cost 
effectiveness based on PSEL will more closely align with cost 
calculations based on actual emissions, yielding cost effectiveness of 
controls calculated to be $10,956 (LNB/FGR), $10,239 (SNCR), and 
$14,237 (SCR).

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

    ODEQ's consideration of imposing SCR as part of the agency's 
preliminary control determination was only possible by using allowable 
emissions well above actual emissions, PSEL emissions (1692 tons per 
year NO<INF>X</INF>) \79\ versus actual 2017 emissions (724 tons per 
year NO<INF>X</INF>).\80\ In addition to the important fuel restriction 
requirements noted by the NPS, SAFO 208850 (effective August 9, 2021) 
was intended by Oregon as an anti-backsliding measure to prevent 
International Paper from future emissions growth during the second 
implementation period that may jeopardize reasonable progress.

    Lastly, with respect to the commenter's recommendation that EPA and 
ODEQ set a NO<INF>X</INF> emission limit consistent with the Good 
Neighbor Plan, we note that Oregon is not subject to the Good Neighbor 
Plan. This regulation was published on June 5, 2023 (88 FR 36654) to 
address the specific issue of human health impacts from ozone 
nonattainment, which has a different regulatory structure and 
requirements than the regional haze program. The EPA already determined 
that Oregon does not cause or contribute to ozone nonattainment in any 
other state.\81\ For the specific set of states subject to the Good 
Neighbor Plan,the rule established emission limits for a broad suite of 
source categories including boilers in Iron and Steel Mills and 
Ferroalloy Manufacturing, Metal Ore Mining, Basic Chemical 
Manufacturing, Petroleum and Coal Products Manufacturing, and Pulp, 
Paper, and Paperboard Mills.\82\ This is distinctively different than 
the regional haze four-factor analysis process which often focuses on 
source-specific factors in the evaluation. Another difference is that 
the emissions limit cited by the NPS applies only during the ozone 
season, directly for the purpose of addressing ozone nonattainment. 
Lastly, the Good Neighbor Plan for ozone estimated average cost-
effectiveness per ton for pulp and paper facilities at $14,134,\83\ 
which is not necessarily comparable to the threshold for determining 
the controls necessary for reasonable progress toward natural 
visibility conditions. Therefore, the NPS would need to provide greater 
detail to

demonstrate the site-specific assumptions used to assert that a 0.08 
lb/mmBtu limit is technically feasible and cost-effective under the 
four-factor regional haze analysis process, especially in light of the 
information in table 3 of this preamble showing that LNB/FGR, SNCR, and 
SCR were only possible for preliminary cost-effectiveness consideration 
using allowable 2017 PSEL emissions (1,692 tpy NO<INF>X</INF>), well 
above actual 2017 emissions (724 tpy NO<INF>X</INF>).\84\

15. Owens-Brockway Glass Container Inc.
    Comment: ``In this specific case, the NPS is aware that ODEQ is 
requiring the installation of controls outside of the regional haze 
process because of violations of the facility's particulate matter and 
opacity limits. The ODEQ issued a construction permit in November 2022 
requiring installation of a new catalytic ceramic filter pollution 
control system that must be installed by June 30, 2024. The system will 
control multiple pollutants, including particulate matter, 
NO<INF>X</INF>, and SO<INF>2</INF>. A draft title V operating permit, 
currently undergoing public review, would impose new PSELs that will 
limit the facility's Q to 127 tons after the controls are installed, 
resulting in a Q/d of about 0.9 for the nearest NPS Class I area, Mount 
Rainier National Park in Washington . . . This control technology was 
also identified as reasonable based on evaluation of the four factors. 
The NPS agrees that installation of the ceramic filter system is 
reasonable and will result in meaningful reductions in haze-causing 
emissions. The NPS recommends EPA require incorporation of this control 
requirement into the regional haze SIP to ensure realization of 
emission reductions from control installation in this planning 
period.''
    Response: The special case of the Owens-Brockway facility is 
discussed in section II.A.3 this preamble. Permit modifications to 
implement the human-health enforcement response are still ongoing.\85\ 
We see no basis for disapproval or continued delay of the regional haze 
SIP action while Oregon completes its human health enforcement 
response, especially considering the 75% emissions reductions from 2017 
actuals and permanent shutdown of Furnace A imposed by ODEQ's August 9, 
2021, regional haze-specific order.\86\

B. Environmental Organizations' Comments

    Complete copies of the Environmental Organizations' comments and 
supporting attachments are included in the docket for this action. For 
readability, we arranged the responses to generally mirror the timeline 
of the Oregon process from site selection, review of controls, and 
imposition of controls.
1. Stationary Source Contribution
    Comment: ``We submitted public comments to Oregon's Department of 
Environmental Quality (``DEQ'') on the state's draft SIP Revision on 
November 1, 2021, and on October 21, 2023, raising several of the same 
issues with Oregon's proposed regulation of stationary sources that 
collectively contribute 80% of the state's regional haze-forming 
emissions.''
    Response: Stationary sources do not contribute 80% of the state's 
regional haze-forming emissions. The emissions inventory analysis in 
Chapter 2.3 of Oregon's 2022 submission shows data from the EPA's 2017 
National Emission Inventory (NEI).\87\ Fuel combustion and process 
emissions associated with stationary sources account for 11% and 6%, 
respectively, of Oregon's PM<INF>10</INF> emissions. Fuel combustion 
and process emissions account for 14% and 4%, respectively of 
NO<INF>X</INF> emissions, with mobile sources accounting for 79% of 
NO<INF>X</INF> emissions. Fuel combustion and process emissions account 
for 57% and 13% of the 2017 SO<INF>2</INF> emissions inventory. 
However, as noted by Oregon, ``The 2017 SO<INF>2</INF> inventory is 
largely overwhelmed by PGE Boardman's coal-fired power plant in Morrow 
County. With the closing of the plant in October 2020, those emissions 
have largely been eliminated, and the remainder of the emissions come 
from fuel combustion and prescribed fires.'' \88\
---------------------------------------------------------------------------

    \87\ See April 22, 2022, regional haze SIP, at page 22-27.
    \88\ See April 22, 2022, regional haze SIP, at page 24.
---------------------------------------------------------------------------

    The Environmental Organizations cite to Oregon's August 27, 2021, 
Notice of Proposed Rulemaking as the basis for the statement that 
stationary sources contribute 80% of the state's regional haze-forming 
emissions. However, the actual wording of the Notice of Proposed 
Rulemaking states, ``Federally enforceable emission reductions and 
pollution controls at Title V stationary sources that collectively 
contribute 80% of Oregon regional haze-forming emissions from 
stationary sources.'' (Emphasis added) \89\ The Environmental 
Organizations' adaptation of this quote omits the important qualifier 
``from stationary sources.'' In intent and practice, ODEQ was referring 
to the EPA's draft regional haze guidance that recommended states set a 
source screening level such that 80% of the stationary source emissions 
inventory was captured. This formed the basis of Oregon's decision to 
set the source screening level at a quantity over distance (Q/d) = 5. 
This was not a statement that stationary sources contribute 80% the 
state's regional haze-forming emissions. Based on the most recent 2023 
National Emissions Inventory trends data,\90\ emissions categories 
associated with stationary sources contribute at most 18% of the 
cumulative anthropogenic PM<INF>10,</INF> NO<INF>X</INF>,

[[Page 81373]]

and SO<INF>2</INF> inventory.\91\ While up to 18% is still a meaningful 
percentage of the overall regional haze precursor inventory, there is 
no evidence to support the claim that stationary sources collectively 
contribute 80% of the state's regional haze-forming emissions.

docket for this action.

    \91\ See 704_Oregon NEI data.xlsx and 705_Original NEI source 
data.xlsx, included in the docket for this action. For the purpose 
of this analysis, we conservatively assumed that all fuel combustion 
was attributable to stationary sources, which likely overestimates 
the contribution from stationary sources.
---------------------------------------------------------------------------

2. Oregon's Regional Haze Rule Is Inconsistent With the CAA
    Comment: The Environmental Organizations assert that Oregon's 
Regional Haze Rule codified at OAR Chapter 340, Division 223 is 
inconsistent on its face with the CAA and 40 CFR 51.308(f). The 
Environmental Organizations make four arguments in support of this 
comment: (1) neither the CAA nor RHR allow Oregon to unilaterally grant 
itself broad authority to establish an alternative compliance process 
that operates outside the Federal regional haze framework; (2) Oregon's 
rules would prevent the state from fulfilling its Federal Regional Haze 
obligations because they allow Oregon to provide a source with 
alternative compliance options that the state has not assessed through 
the four-factor analysis process; (3) Oregon's rules do not require 
ODEQ to document the technical basis for its alternative compliance 
decisions; and (4) Oregon's regional haze rule gives ODEQ the authority 
to reevaluate and reject controls deemed necessary for reasonable 
progress.
    Response: For the reasons stated below, we disagree with each of 
these comments. Before turning to each of the Environmental 
Organizations' points, we note that these comments conflict with these 
same Organizations' prior comments on Oregon's Regional Haze Rule. 
Oregon's Regional Haze Rule was adopted by the Oregon Environmental 
Quality Commission after a full public comment period from May 28, 
2021, to June 30, 2021, and a hearing conducted on June 28, 2021.\92\ 
Earthjustice, on behalf of the Cully Air Action Team, Earthjustice, 
Friends of the Columbia Gorge, Green Energy Institute, Oregon 
Environmental Council, National Parks Conservation Association, 
Neighbors for Clean Air, Northwest Environmental Defense Center, and 
Verde submitted comments supportive of the rulemaking stating, ``We 
write in support of DEQ's proposed revisions to Oregon's Regional Haze 
rules. The revised rules reflect a reasoned, well-grounded, and 
pragmatic plan for implementing the Clean Air Act's visibility 
requirements. They will also benefit many communities in Oregon that 
are disproportionately burdened by pollution from emissions of PM, 
SO<INF>2</INF>, and NO<INF>X</INF> and communities that are most 
vulnerable to the most harmful effects of climate change. [The Clean 
Air Act requires] each state's strategy must be based on an analysis of 
emission control measures that are necessary to make ``reasonable 
progress'' towards the goal of restoring natural visibility to Class I 
areas. The emissions-reducing strategies in DEQ's revised Division 223 
rules are consistent with EPA requirements for round II state 
implementation plans. The revised rules provide a strong foundation for 
Oregon's long-term strategy for reducing anthropogenic pollutants that 
impair visibility.''
---------------------------------------------------------------------------

    \92\ See 702_staff report EQC 
meeting_072321_ItemJ_RegionalHaze.pdf.
---------------------------------------------------------------------------

    Thus, the Environmental Organizations took full advantage of their 
opportunity to raise concerns with Oregon's Regional Haze Rule during 
the state public comment process. At that time, the Organizations were 
highly supportive of the rule and gave ODEQ the clear impression that 
their rule was consistent with the CAA. The Environmental Organization 
do not address their stark change in position in their current comments 
on EPA's proposal nor repudiate their prior position. This gives the 
impression that the Environmental Organizations are concerned with 
ODEQ's application of Oregon's Regional Haze Rule, rather than the rule 
itself. Nevertheless, we address each of the Environmental 
Organizations' arguments against Oregon's Regional Haze Rule.
    First, we disagree that Oregon's Regional Haze Rule is disconnected 
from or inconsistent with the Federal Regional Haze Rule. Oregon 
adopted rules to implement the regional haze program at OAR Chapter 
340, Division 223. The Division includes sections on source screening, 
four-factor analysis, options for compliance, and final orders 
requiring compliance. The source screening section establishes which 
sources are subject to Oregon's regional haze rules. Under the rule, 
all sources with a Title V operating permit and with a Q/d greater than 
or equal to 5 based on PSELs are subject to the regional haze rule. All 
sources subject to Oregon's regional haze rule must submit a four-
factor analysis to ODEQ in accordance with OAR 340-223-0110(1) that 
meets the requirements of OAR 340-223-0120. The factors in OAR 340-223-
0120 mirror those in the CAA section 169A(g)(1) and 40 CFR 
51.308(f)(2)(i). As discussed in section II.A of this preamble, under 
OAR 340-223-0120(2) and (3), ODEQ is authorized to adjust the four-
factor analysis to account for inaccuracies or insufficient 
information, and for consistency purposes. The rule further authorizes 
ODEQ to determine which controls would be cost effective and the time 
period the controls can be implemented.
    The regulations at OAR 340-223-0110 lay out the administrative 
mechanisms for imposing regional haze controls. Under this section and 
OAR 340-223-0130, ODEQ has the authority to order the source to install 
controls that ODEQ determines are cost effective on a timeline that 
ODEQ prescribes. Such orders are subject to appeal by the source. 
Alternatively, ODEQ may offer sources subject to the regional haze 
program the opportunity to enter into a SAFO. The rule provides five 
compliance options if ODEQ elects to enter into a SAFO: (1) lower PSELs 
to below Q/d equal to 5; (2) install controls identified by the source 
in a four factor analysis as cost effective for that source, provided 
ODEQ agrees that the controls will result in the greatest cost 
effective reductions; (3) install controls or reduce emissions that 
ODEQ determines, in its sole discretion, provide equivalent emissions 
reductions to controls that would be identified as cost effective for 
that source; (4) maintain controls that the source has already 
installed or maintain reduced emissions that ODEQ determines in its 
sole discretion have provided and will continue to provide equivalent 
reductions to controls that would be identified as cost effective for 
that source; and (5) replace emission unit with a new emission unit 
that meets the emission limits and requirements of the most recent 
applicable standard in place at the time of the permitting of the new 
emissions unit.
    Conceptually, nothing in the CAA nor the Federal Regional Haze Rule 
requires that states promulgate a regional-haze-specific state rule at 
all nor the form such a rule must take if a state elects to do so. 
Rather, the CAA and Regional Haze Rule provide states discretion on the 
manner in which they implement the regional haze program so long as the 
state's long-term strategy includes the enforceable emissions 
limitations, compliance schedules, and other measures that are 
necessary to make reasonable progress as determined based on a 
consideration of the four statutory factors and the state documents the 
technical basis for its decisions on the controls necessary for 
reasonable

[[Page 81374]]

progress. As we discussed in the proposal and herein, Oregon's SIP 
submissions demonstrate that the state has done so.
    Moreover, each of the compliance options in OAR 340-223-0110(2) are 
either part of Oregon's source selection methodology or grounded in the 
four-factor analysis required by OAR 340-223-0110(1) and 0120. 
Throughout their comments, the Environmental Organizations reflect 
concerns with the term ``alternative compliance'' used to describe the 
administrative mechanism in OAR 340-223-0110(2) for ODEQ to enter into 
a SAFO with a source rather than a unilateral order. We do not 
interpret this as an alternative to the requirements of the CAA or 
Regional Haze Rule. Rather, entering into a SAFO is an alternative 
administrative mechanism to imposing controls necessary for reasonable 
progress. Our review of the subsections of OAR 340-223-0110(2) shows 
they are consistent with the CAA and Regional Haze Rule.
    The option to lower PSELs is discussed at length in sections II.A 
and II.B.3 of this preamble. This option is part of Oregon's method for 
selecting sources to undergo review and is consistent with the Regional 
Haze Rule. Each of the options in OAR 340-223-0110(2)(b)(B)-(D) make 
clear that ODEQ references the four-factor analysis as the basis to 
determine the acceptability of those options. For the option in OAR-
340-223-0110(2)(b)(E) regarding emission unit replacement, ODEQ 
reasonably anticipated that sources would not evaluate unit replacement 
as a control option in a four-factor analysis,\93\ but that unit 
replacement may be more cost effective or provide significantly greater 
emissions reductions than certain add-on controls or emissions 
limitations in existing emission units. Therefore, contrary to the 
Environmental Organizations' contention, these compliance options are 
grounded in the Regional Haze Rule.
---------------------------------------------------------------------------

    \93\ 2019 Regional Haze Guidance at p. 29.
---------------------------------------------------------------------------

    The Environmental Organizations appear to center their concerns on 
OAR 340-223-0110(2)(b)(C) and (D), which allow ODEQ to issue a SAFO 
that requires the source to install or maintain controls that achieve, 
in ODEQ's sole discretion, controls that provide equivalent emission 
reductions to controls that would be identified as cost effective for 
that source following the adjustment and review of the four-factor 
analysis. Oregon is subject to state administrative procedural 
requirements that require public review of the basis for its 
decisions.\94\ In addition, we interpret Oregon's inclusion of the 
phrase ``in its sole discretion'' in OAR 340-223-0110(2)(b)(C) and (D) 
as necessary to preserve the durability of its SAFOs. Under OAR 340-
223-0110(2), ODEQ has discretion to offer sources the option to impose 
controls necessary for reasonable progress through a SAFO rather than a 
unilateral order. A benefit of the SAFO option is avoiding an appeal 
under OAR 340-223-0130. Given this, Oregon was reasonable in 
foreclosing the possibility of a source, after having signed a SAFO 
agreeing to install controls, challenging whether the agreed upon 
control was equivalent to the controls identified as cost effective 
under four-factor analysis. Finally, we do not interpret OAR 340-223-
0110(2)(b) as overriding EPA's authority under CAA Section 110 to 
determine whether the SIP submission meets CAA requirements nor the 
requirement in 40 CFR 51.308(f)(2)(iii) to document the basis for its 
decisions. As discussed in sections II.A.1, II.A.2, II.A.4, and II.B.5 
of this preamble, in practice, ODEQ included in its SIP submission all 
of the correspondence that formed the basis for its determinations of 
what controls are necessary for reasonable progress.
---------------------------------------------------------------------------

    \94\ See 001_1.1_StaffReport_wAttachments.pdf at p. 19; 
015_4.1.1 SOS.Notice.FilingReceipt.8.27.21.pdf; Oregon Revised 
Statutes sections 183.310-183.690; OAR 340-011-0009.
---------------------------------------------------------------------------

    Second, with respect to the Environmental Organizations' argument 
that Oregon's regional haze rule prevents the state from fulfilling its 
regional haze obligations, ODEQ chose the compliance options in OAR 
340-223-0110(2)(b) as the regulatory mechanism to effectuate its 
determinations of the controls necessary for reasonable progress based 
on the four factor analyses conducted under OAR 340-223-0120. As we 
stated in the proposed rulemaking for this action, reasonable progress 
analysis, including source selection, information gathering, 
characterization of the four statutory factors (and potentially 
visibility), balancing of the four factors, and selection of the 
emission reduction measures that represent reasonable progress, is a 
technically complex exercise, but also a flexible one that provides 
states with bounded discretion to design and implement approaches 
appropriate to their circumstances.\95\
---------------------------------------------------------------------------

    \95\ See 89 FR 13622 at 13629 (February 23, 2004).
---------------------------------------------------------------------------

    Accordingly, Oregon's regional haze rule requires ODEQ to make its 
equivalency determination based on the outcome of the four-factor 
analysis. Thus, we do not view Oregon's rules as permitting ODEQ to 
determine the controls necessary for reasonable progress without 
considering the four statutory factors but rather recognizing that in 
practice a four-factor analysis may not always yield a single, obvious 
control determination. As discussed in section II.A of this preamble, 
in practice, ODEQ carefully considered the four factors in determining 
the controls necessary for reasonable progress and the appropriate 
regulatory mechanism under OAR 340-223-0110(2)(b).
    Practically, the goal of the regional haze program is to impose 
enforceable emission limits, where possible expressed as a numerical 
emission limit.\96\ Oregon's rules allow it to impose such a limit 
without rigidly adhering to a specific control technology. Nothing in 
the CAA nor regional haze rule prohibits this approach to achieving 
reasonable progress.
---------------------------------------------------------------------------

    \96\ Clarifications Memo at pp. 11-12.
---------------------------------------------------------------------------

    Third, regarding documentation requirements, we do not interpret 
OAR 340-223-0110(2)(b) as circumventing ODEQ's state administrative 
procedural requirements to include in its public record the basis for 
its regulatory decisions.\97\ OAR 340-223-0120 requires ODEQ to include 
in its record the additional information it uses to adjust the initial 
four factor analysis. Moreover, Oregon is subject to the Regional Haze 
Rule requirement to include in it SIP submission documentation of the 
technical basis, including modeling, monitoring, cost, engineering, and 
emissions information, on which the state is relying to determine the 
emission reduction measures that are necessary to make reasonable 
progress in each mandatory Class I Federal area it affects.\98\ In 
recognition of this requirement, ODEQ supplemented its initial SIP 
submission with considerable documentation that informed the state's 
determination of the controls necessary for reasonable progress.
---------------------------------------------------------------------------

    \97\ See OAR 340-011-0010 and 0024; See also 40 CFR 51.102.
    \98\ See 40 CFR 51.308(f)(2)(iii).
---------------------------------------------------------------------------

    Finally, the EPA disagrees with the Environmental Organizations' 
argument that Oregon's regional haze rule allows the state to 
reevaluate and reject control measures deemed necessary for reasonable 
progress. This comment is predicated on the Environmental 
Organizations' incorrect interpretation of ODEQ's process for 
determining the controls necessary for reasonable progress. The 
Environmental Organizations presume that ODEQ's preliminary control 
determinations

were its final control determinations. This is incorrect. See sections 
II.A, II.B.4, II.B.5 and II.B.6 of this preamble for EPA's 
interpretation and explanation of ODEQ's process.
    Under the Clean Air Act, the Administrator is required to approve a 
SIP submission that complies with the provisions of the Clean Air Act 
and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). 
Thus, in reviewing SIP submissions, the EPA's role is to approve state 
choices, provided that they meet the criteria of the Clean Air Act. 
Accordingly, this action approves the submitted state regulations as 
meeting Federal requirements.
3. Oregon's Use of PSEL Reductions as a Source Selection Method
    Comment: The Environmental Organizations also commented that ODEQ's 
application of Oregon's regional haze rule was inconsistent with the 
CAA and the Regional Haze Rule. The Environmental Organizations took 
issue with ODEQ's use of PSEL reductions stating: ``DEQ used Oregon's 
alternative compliance process to offer facilities that screened into 
the Regional Haze program an option to screen back out from the program 
by agreeing to measures that would reduce their plant site emission 
limits (``PSEL'') so that Q/d would be below 5.00. This resulted in 
only 23 of the 32 screened-in sources completing the required four-
factor analyses and allowed four of those 23 sources to belatedly 
screen back out from the program by reducing their PSELs so that Q/d is 
below 5.00.''
    Response: The regulatory provision cited by the Environmental 
Organizations is ODEQ's application of Oregon Administrative Rules 
(OAR) 340-223-0110(2)(b)(A) which allows a source to accept federally 
enforceable reductions of combined plant site emission limits (PSELs) 
of regional haze pollutants to bring the source's Q/d below 5. As 
stated in section II.B.2 of this preamble, this regulatory provision 
was adopted by the Oregon Environmental Quality Commission after a full 
public comment period from May 28, 2021, to June 30, 2021, and a 
hearing conducted on June 28, 2021.\99\ The Environmental Organizations 
expressed support for Oregon's Regional Haze Rule, including the PSEL 
reduction option at that time. We also note that the option to limit 
PSELs aligns with Oregon's use of PSELs to initially select sources. 
Given that the state based initial source selection on PSELs (i.e. 
allowables), Oregon offered the option for sources to lower PSELs below 
the significance threshold to satisfy reasonable progress (prevention 
of future impairment) under the regional haze program.

meeting_072321_ItemJ_regionalhaze.pdf.
---------------------------------------------------------------------------

    For the following reasons, we disagree with the Environmental 
Organizations' comments with respect to ODEQ's use of enforceable and 
permanent PSEL reductions as a means of refining source-screening or as 
a means of addressing reasonable progress for facilities with actual 
emissions below the screening threshold. As discussed in section II.A.3 
of this preamble regarding similar comments submitted by the NPS, 
Oregon chose to use a more stringent methodology than the EPA's 2019 
guidance for source screening and cost analysis based on allowable PSEL 
emissions rather than recent actual emissions or 2028 projected 
emissions.\100\ Oregon intended this as (1) a method of initially 
capturing a broad selection of sources potentially impacting visibility 
in Class I areas and (2) as an anti-backsliding measure to ensure that 
facilities which had a Q/d less than 5 based on 2017 actual emissions 
(and would otherwise not be screened into analysis) do not have future 
emissions growth (based on allowable PSEL emissions) that could 
jeopardize reasonable progress. Pursuant to OAR 340-223-0110(2)(b)(A), 
Oregon entered into SAFOs to reduce allowable PSEL emissions to align 
with 2017 actual emissions. None of the facilities listed in table 4 
would have been screened into review based on 2017 actual emissions.

    The Environmental Organizations provided no compelling basis to 
demonstrate that aligning allowable PSEL emissions with actual 
emissions was a violation of regional haze requirements, especially 
when 2017 actual emissions are below the Q/d = 5 screening threshold.
---------------------------------------------------------------------------

    \101\ April 29, 2022 Oregon SIP submission, Chapter 3.7 
Facility-specific findings and results.
---------------------------------------------------------------------------

    For the two special cases where 2017 actual emissions were above Q/
d = 5, Kingsford Manufacturing and Owens-Brockway, ODEQ had a reasoned 
basis for imposing permanent and enforceable emissions reductions such 
that the source's Q/d is less than 5. In the case of Kingsford 
Manufacturing, the facility already had a 2019 permit modification 
lowering emissions below Q/d = 5 prior to the development of four-
factor analyses.\102\ It was reasonable for ODEQ to consider this 
contemporaneous 2019 emissions information in updating the agency's 
source screening in 2020. The case of Owen-Brockway is more complex and 
described in our response to comment in sections II.A.3, II.A.15, and 
II.B.6 of this preamble.

    The Environmental Organizations focus on Boise Cascade Wood 
Products, LLC--Medford, Gas Transmission Northwest LLC--Compressor 
Station 12, JELD-WEN, and Northwest Pipeline LLC--Baker Compressor 
Station. These

[[Page 81376]]

facilities all conducted four-factor analyses under OAR 340-223-0120 
and then subsequently took a PSEL limit under OAR 340-223-
0110(2)(b)(A). As we stated in section II.A of this preamble, Oregon 
determined that controls on sources with a Q/d of less than 5 based on 
PSELs are not necessary to make reasonable progress in the second 
planning period. The Environmental Organizations do not challenge this 
in their comments. Indeed, this is a particularly conservative source-
selection method. Thus, Oregon was reasonable in not imposing controls 
based on a four-factor analysis for sources that have permanent and 
enforceable emissions limits such that their Q/d values are less than 5 
based on PSELs.
    Moreover, as shown in table 5 of this preamble, there was only one 
control identified in the submitted four-factor analyses that was below 
the $10,000 cost per ton reduced threshold when calculated using PSEL 
(SCR at Gas Transmission Northwest LLC--Compressor Station 12). 
However, when calculated using 2017 actual emissions or projected 
actual emissions, the cost per ton reduced of SCR increased to $32,071 
and $15,386, respectively. Considering the EPA's guidance that 
recommends the use of recent actuals or projected actuals in 
calculating cost-effectiveness, it was reasonable for ODEQ to offer the 
facility a PSEL reduction under OAR 340-223-0110(2)(b)(A) to align with 
actual emissions, especially when 2017 actual emissions at the facility 
were so far below the screening threshold (Q/d = 2.33).

    Finally, the lowering PSELs increases the likelihood that certain 
sources will be subject to NSR. ODEQ uses PSELs to manage emissions 
increases and decreases throughout the state to maintain the NAAQS and 
protect visibility.\108\ Accordingly, changes to PSELs trigger Oregon's 
state and Federal new source review programs.\109\ The applicability 
trigger often hinges on the increase in emissions over the netting 
basis.\110\ The regulations also allow for deduction of certain 
unassigned emissions when determining whether an emission change 
requiring NSR occurs.\111\ In several cases, ODEQ ordered the reduction 
of PSELs, the zeroing out of unassigned emissions, and reduction of the 
netting basis.\112\ This increases the likelihood that the source will 
be subject to NSR and associated control technology review in the 
future.
---------------------------------------------------------------------------

    \103\ Under OAR 340-223-0120, ODEQ required calculation of cost-
effectiveness based on PSEL. However, Gas Transmission Northwest LLC 
was one of several facilities to provide cost-effectiveness based on 
recent actuals or projected actuals. To the extent supplementary 
information was available for a facility, the EPA added it to our 
analyses and tables.

4. Oregon's ``Alternative Compliance'' Pathways
    Comment: The Environmental Organizations asserted generally that 
ODEQ's SAFOs were not outgrowths of ODEQ's considerations of the four-
factor analysis. In the introduction portion of their comments, the 
Environmental Organizations asserted: ``And instead of ordering all 17 
facilities that completed four-factor analyses to implement the 
reasonable progress controls identified through those analyses, DEQ 
chose to offer agreements to all but one of the facilities--enabling 
them to evade the regional haze process. These agreements allowed 
sources to accept alternative emission reduction measures that will 
achieve far fewer reductions in haze-forming emissions than the highly 
effective pollution controls that DEQ originally identified in its 2021 
control letters. The emission reductions measures in the agreements 
were not vetted through the four-factor analysis process. DEQ entered 
into the agreements without analyzing, determining, or demonstrating 
that they would result in emissions reductions equivalent to those 
reductions that would have occurred had the sources been required to 
install the controls identified through four-factor analyses.''
    Response: The Environmental Organizations argue that all changes 
from the January 2021 preliminary control determination letters to the 
final August 2021 control determinations are attributable to 
considerations other than regional haze. The EPA acknowledges that 
ODEQ's process was challenging to follow. However, in our review of the 
record, we have determined that ODEQ established these agreements 
within the framework of the Regional Haze Rule and the four statutory 
factors.
    Under OAR 340-223-0110(1) all affected facilities were required to 
submit four-factor analyses that comply with OAR 340-223-0120, which 
mirrors the Federal statutory requirement to consider the four 
statutory factors as outlined in CAA section 169A(g)(1) and 40 CFR 
51.308(f)(2). Except for Owens-Brockway and Gilchrist Forest Products, 
twenty-one facilities provided four-factor demonstrations asserting 
``no feasible, cost-effective'' controls were available. In issuing the 
January 2021 preliminary determination letters, ODEQ began the process 
of disputing the claims of ``no feasible, cost-

[[Page 81377]]

effective'' controls in the four-factor analyses. As discussed in 
section II.A.2 of this preamble, these letters were not four-factor 
analyses themselves or determinations of the controls necessary for 
reasonable progress under OAR 340-223-120(4) or 40 CFR 51.308(f)(2). 
Rather, a plain reading of the letters and documentation provided by 
ODEQ indicates these letters were interim steps in ODEQ's refinement of 
the initial four-factor analyses. Given that ODEQ invited the 
recipients of the letters to discuss the preliminary findings with 
ODEQ, ODEQ clearly anticipated further refinements to the analyses. In 
this context, ODEQ appropriately initiated this interim process by 
asserting the most stringent measures that might be possible.
    Furthermore, the Environmental Organizations appear to ignore or 
mischaracterize the important correspondence included in appendices 1 
through 6 included in both the state's docket for the 2023 regional 
haze supplement and the docket for the EPA's proposed rulemaking.\113\ 
The initial four-factor analyses, ODEQ's refinement and preliminary 
letters, and this supplemental information collectively formed the 
basis for ODEQ's determination of the controls necessary for reasonable 
progress. Each of these steps in the process and associated 
documentation evince ODEQ's consideration of the four statutory factors 
consistent with 40 CFR 51.308(f)(2).
---------------------------------------------------------------------------

    \113\ Documents 246 through 251 of the docket.
---------------------------------------------------------------------------

    The Environmental Organizations argue that because ODEQ's 
determination of the controls necessary for reasonable progress 
differed in some cases from the preliminary determinations that its 
final determinations could not have been based on a consideration of 
the four statutory factors. The EPA disagrees. As detailed in our 
facility-specific responses to NPS's comments, we have reviewed the 
correspondence and confirmed that ODEQ considered the four factors in 
making final control determinations. The supplemental correspondence 
indicates that ODEQ focused extensively on the technological 
feasibility of controls, cost of controls, and the time necessary for 
compliance. As discussed in our responses to NPS's comments in section 
II.A. of this preamble, ODEQ not choosing BACT-level controls or other 
controls advocated by the NPS and the Environmental Organizations does 
not mean that Oregon did not consider the four statutory factors. 
Section II.A of this preamble details our facility-specific findings 
under the four factors. In each case, Oregon had a rational basis under 
the four factors in making final determinations.
    Comment: In the analysis section of their comments, the 
Environmental Organizations asserted: ``Neither the Clean Air Act nor 
Regional Haze Rule allow EPA or Oregon to reject viable controls 
identified through a four-factor analysis and offer sources alternative 
compliance measures that have not been analyzed against the four 
statutory factors, and which will not yield equivalent emission 
reductions. EPA's proposal to approve Oregon's alternative compliance 
agreements violates the principle that state determinations concerning 
the selection and implementation of controls necessary to meet 
reasonable progress requirements must be `reasonably moored' to the 
Clean Air Act, including the four factors listed in the statute.''
    Response: We agree with the general principle that a state's 
reasonable progress determinations must be based on consideration of 
the four statutory factors. As we stated in the proposal, 40 CFR 
51.308(f)(2)(i) requires states to determine the emission reduction 
measures for sources that are necessary for reasonable progress by 
considering the four statutory factors. We disagree with the 
implication that Oregon did not do so. As we state in response to 
similar comments, the Environmental Organizations' argument rests on 
the premise that ODEQ's preliminary determination letters represented 
the culmination of the ODEQ's consideration of the four statutory 
factors and foreclosed any further consideration of those factors. This 
is incorrect.
    ODEQ's SIP submission makes clear that ODEQ concluded its 
consideration of the four factors subsequent to these letters, after 
the sources provided additional information regarding the availability 
of controls, cost of compliance, energy and non-air quality impacts of 
the controls, and time necessary to install the controls.\114\ The 
commenters do not explain how ODEQ's consideration of the four factors 
prior to the preliminary determination letters is acceptable, but its 
consideration of the four factors after the letters is unacceptable.
---------------------------------------------------------------------------

    \114\ See appendices 1-6 of Oregon's 2023 supplement.
---------------------------------------------------------------------------

    Our review of the information ODEQ included in the SIP submission 
indicates that ODEQ's determinations of the controls necessary for 
reasonable progress, particularly where its final determinations 
differed from its preliminary determinations, reflect ODEQ's careful 
consideration of technical feasibility and cost of controls--not an 
attempt to circumvent the requirements of 40 CFR 51.308(f)(2) as the 
commenters suggest. The EPA recognized in the proposal that reasonable 
progress analysis, including source selection, information gathering, 
characterization of the four statutory factors (and potentially 
visibility), balancing of the four factors, and selection of the 
emission reduction measures that represent reasonable progress, is a 
technically complex exercise, but also a flexible one that provides 
states with bounded discretion to design and implement approaches 
appropriate to their circumstances.\115\ ODEQ's process of considering 
the four factors and for determining the controls necessary for 
reasonable progress reflect the technical challenges associated with 
installing retrofit controls on diverse industrial processes. For each 
source, the EPA is satisfied that ODEQ has done so.

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

    Comment: The Environmental Organizations further asserted that ODEQ 
did not follow its own rules in entering into SAFOs. The Environmental 
Organizations asserted that ODEQ did not adequately determine whether 
the emissions reductions expected from each SAFO were equivalent to the 
emission reductions projected from the controls ODEQ preliminarily 
determined were cost effective in its letters to the sources. The 
Organizations stated: ``But nothing in the record suggests that DEQ 
actually analyzed the emission reductions that would result from the 
alternative compliance agreements or compared them to the emission 
reductions that would result from installing controls identified 
through four-factor analyses. Many of the agreements contain several 
compliance options for the source that will not deliver equal emissions 
reductions. But rather than analyze the emissions expected from each of 
the compliance pathways, it appears that DEQ abandoned any effort to 
quantify the reductions expected from the agreements, stating in its 
response to comments that it did not have adequate information to allow 
it to determine equivalency with precision.'' The Environmental 
Organizations further asserted that based on their own analysis, ODEQ's 
SAFOs will achieve far less emission reductions than the controls ODEQ 
initially determined were cost effective in its preliminary control 
letters to sources.

[[Page 81378]]

    Response: First, the Regional Haze Rule requires that the state 
determine the controls necessary for reasonable progress based on a 
consideration of the four statutory factors. As we explained in the 
Proposal and herein, Oregon's submission clearly demonstrates that it 
considered the four statutory factors in determining the controls 
necessary for reasonable progress.
    Second, Oregon followed its own rules in determining the controls 
necessary for reasonable progress. As stated above, the EPA disagrees 
that the preliminary control determinations represented ODEQ's final 
four factor analysis. Therefore, these preliminary determinations are 
not the correct barometer to measure whether an emission control will 
achieve equivalent emission reductions under OAR 340-223-0110(2)(C) or 
(D).
    A careful review of the SIP submission indicates that ODEQ invoked 
OAR 340-223-0110(2)(C) once in the case of the International Paper--
Springfield Mill and OAR 340-223-0110(2)(D) once in the case of 
Roseburg Forest Products--Dillard. We discuss at length the 
appropriateness of ODEQ's reasonable progress determination for the 
International Paper--Springfield Mill in section II.A of this preamble. 
As documented in appendix 6 of ODEQ's 2023 regional haze supplement, 
International Paper responded to ODEQ's preliminary determination in a 
letter dated February 2, 2021, and a supporting memorandum dated March 
15, 2021.\116\ This information was cited in ODEQ's 2023 supplement as 
the basis for revising the preliminary determination, ``On February 2, 
2021, IP Springfield submitted a letter in response to DEQ's 
preliminary determination, explaining that the cost effectiveness of 
SCR installation was above the $10,000 per ton threshold for 
consideration.'' \117\ The Environmental Organizations provided no 
analysis or review of this follow-up correspondence to support the 
claim that ODEQ failed to ``provide equivalent emissions reductions to 
controls that would be identified as cost effective for that source 
following the adjustment and review of a four-factor analysis.'' SAFO 
208850, effective August 9, 2021, requiring PSEL reductions, 
installation of CEMS, and fuel restrictions is precisely what ODEQ 
identified as cost effective for that source following the adjustment 
and review of a four-factor analysis.

    With respect to Roseburg Forest Products, ODEQ did not issue a 
preliminary determination letter to the source, but indicated in its 
SIP submission that it initially approached the source with 
installation of SNCR on Boilers Nos. 1-3. The SIP submission indicates 
that the source and ODEQ then considered whether the Boiler Nos. 1, 2 
and 6 could achieve a similar emission reduction by optimizing 
operations of the boilers. This engagement culminated in a SAFO that 
imposes an emission limit of 0.27 lb. NO<INF>X</INF>/mmBTU (7-day 
rolling average) for Boiler No. 1 and 0.26 lb. NO<INF>X</INF> for 
Boiler Nos. 2 and 6 (7-day rolling average).\118\ The SAFO gave the 
facility the choice to achieve the emission limit either through 
installing SNCR or through boiler optimization.\119\ As discussed in 
section II.B.2 of this preamble, the goal of the regional haze program 
is to impose enforceable emission limits, where possible expressed as a 
numerical emission limit.\120\ Oregon's rules allow it to impose such a 
limit without rigidly adhering to a specific control technology. 
Nothing in the CAA nor Regional Haze Rule prohibits such a pragmatic 
approach to achieving reasonable progress.

5. Documentation of Oregon's Four-Factor Analysis Process
    Comment: ``Additionally, the portion of Oregon's SIP Revision that 
EPA points to as supporting EPA's conclusion that Oregon adequately 
considered the four statutory factors does not contain any analysis of 
the alternative compliance measures. In this section of the SIP 
Revision, [O]DEQ merely explains that it sent sources control letters 
identifying cost-effective controls but later entered alternative 
compliance agreements without explaining its decision to include 
different and weaker controls in those agreements or how the agreements 
reflect the four statutory factors. For some sources, DEQ generally 
explains that the sources sent DEQ memoranda claiming that controls 
identified in the 2021 control letters were not technically feasible or 
cost-effective but DEQ does not include those letters in the SIP 
Revision, preventing EPA and the public from reviewing the source 
analyses. Nothing in the record supports a finding that Oregon analyzed 
these alternative compliance measures based on the four statutory 
factors.''
    Response: Section 5 of Oregon's 2023 regional haze supplement was 
added to explain changes from the January 2021 ``Preliminary 
Determination of Cost Effective Controls for Regional Haze'' letters 
(preliminary determinations) to the final four-factor determinations 
imposed by the August 2021 SAFOs. The 2023 supplement also contained 
appendices 1 through 6 that included the four-factor analyses submitted 
pursuant to OAR 340-223-0110(1), ODEQ's January 2021 ``Preliminary 
Determination of Cost Effective Controls for Regional Haze'' letters, 
and the correspondence from facilities in response to the preliminary 
determinations. As discussed in our facility-specific responses to NPS 
comments, our review showed that ODEQ's consideration of the 
correspondence in appendices 1 through 6 was grounded in the four 
factors in CAA section 169A(g)(1) and 40 CFR 51.308(f)(2) in making 
final control determinations.
    Contrary to the commenters' assertions, the documentation provided 
in Oregon's SIP submissions provide important context for understanding 
the Oregon process in comparing the final control determinations 
imposed by the August 2021 SAFOs to the four-factor analyses submitted 
to pursuant to OAR 340-223-0110(1). Except for Gilchrist Forest 
Products and Owens-Brockway, all four-factor analyses developed by 
environmental consulting firms and/or professional engineers on behalf 
of the sources determined that no feasible, cost-effective controls 
were available, or that further site-specific engineering analysis 
would be necessary. Examples are the June 2020 four-factor analyses for 
the Cascade Pacific Pulp--Halsey, Georgia-Pacific--Wauna, Georgia-
Pacific--Toledo, and International Paper--Springfield facilities.\121\ 
Chapter 2.3.1 Site-Specific Factors Limiting Implementation of the 
four-factor analysis states, ``Currently known, site-specific factors 
that would limit the feasibility and increase the cost of installing 
additional controls include space constraints. A detailed engineering 
study for each of the controls evaluated in this report would be 
necessary before any additional controls were determined to be feasible 
or cost effective.'' \122\ As documented in appendices 1-6 of the 2023 
regional haze supplement, it was precisely these types of technical 
feasibility and cost

concerns that ODEQ considered both before and after issuing the 
agency's preliminary determinations in determining the controls 
necessary for reasonable progress.\123\

6. Owens-Brockway Glass Container Inc.
    Comment: The Environmental Organizations referenced ODEQ's 
evaluation of the four-factor analysis and SAFO for the Owens-Brockway 
Glass Container facility in support of its argument that ODEQ's 
alternative compliance mechanisms are not reasonably moored to the four 
statutory factors. The Organizations stated: ``In the case of Owens-
Brockway, for example, describing DEQ's alternative compliance 
agreement simply as an ``agreed order to impose additional controls'' 
is an especially large distortion of what Oregon did. An order that 
tracked the four-factor analysis for Owens-Brockway would have required 
the installation of ceramic catalytic filters on its furnaces that 
would have reduced the facility's NO<INF>X</INF> and SO<INF>2</INF> 
emissions by 90% and PM<INF>10</INF> emissions by 99%. Community 
members had long been advocating for this kind of pollution control and 
the much-needed reductions in pollution in an already overburdened 
neighborhood that ceramic catalytic filters would have delivered. But 
rather than order Owens-Brockway to install the filters, DEQ and Owens-
Brockway entered into an ``alternative compliance'' agreement that 
consisted of reduced permit limits and a reiteration of a previous DEQ 
order to retire Furnace A, which DEQ had imposed on the facility 
earlier through an enforcement action. Because the permit limits that 
were reduced in the agreement had been set at a level that covered two 
furnaces (one of which was no longer operating), and because Owens-
Brockway had already been ordered to stop operating one of the 
furnaces, Owens-Brockway's ``alternative compliance'' agreement will 
not have an impact on the actual emissions from the facility.''
    Response: In a four-factor analysis dated June 12, 2020, Owens-
Brockway Glass Container Inc. (Owens-Brockway) was one of the few 
facilities in Oregon determining technically feasible, cost-effective 
controls were available under the regional haze program.\124\ On 
October 27, 2020, ODEQ concurred with Owens-Brockway's findings that 
combined control of NO<INF>X</INF>, SO<INF>2</INF> and PM by catalytic 
ceramic filters is cost-feasible for glass-melting furnaces A & D.\125\ 
Subsequently, in 2021, ODEQ initiated an enforcement action at Owens-
Brockway to address exceedances of the total particulate matter and 
opacity limits in the source's operating permit impacting human 
health.\126\ While the enforcement action was pending, ODEQ initiated 
and completed its public comment process for its Regional Haze SIP 
(completed August 27, 2021). ODEQ elected not to impose the catalytic 
ceramic filter requirement through a regional haze unilateral order or 
SAFO because it did not want to circumvent its enforcement process for 
the permit exceedances. Therefore, Oregon limited the scope of the 
regional haze order (SAFO 26-1876) to permanently enshrine the shutdown 
of furnace A (which had not operated since June 8, 2020) and lower the 
PSEL to capture this reduction in emissions.\127\ The lowered PSELs 
resulted in a Q/d of less than 5.0, below Oregon's regional haze rule 
applicability threshold.

    \127\ See 151_SAFOOwensBrockway0840001.pdf, included in the 
docket for this action.
---------------------------------------------------------------------------

    Ultimately, ODEQ's enforcement action resulted in order AQ/V-NWR-
2020-208 (effective October 22, 2021) which required Owens-Brockway to 
either shutdown furnace D or install catalytic ceramic filtration on 
furnace D.\128\ The Environmental Organizations downplay the 
significance of the enforcement response and ongoing permit 
modification to impose catalytic ceramic filtration on furnace D.\129\ 
Given the circumstances, ODEQ was reasonable in calibrating its 
regional haze SAFO to reduce PSELs, while deferring the human-health 
driven relief to its enforcement response. ODEQ's prudence is evidenced 
by the fact that it achieved both PSEL reductions and the installation 
of catalytic ceramic filters on furnace D by leveraging both 
authorities.

7. Reasonable Progress Goals
    Comment: ``EPA wrongfully proposes to find that Oregon's SIP 
Revision satisfies the Regional Haze Rule's requirements for reasonable 
progress goals. In its proposal, EPA acknowledges that Oregon's 
reasonable progress goals are based on ``modeling which represents 
regulations on the books as of 2020 plus stationary source controls 
recommended from DEQ's review of the four-factor analyses submittals.'' 
This confirms that the reasonable progress goals are based on Oregon's 
2021 control letters, not the weaker controls in the alternative 
compliance agreements that were ultimately incorporated into the long-
term strategy. EPA therefore cannot claim that Oregon satisfied the 
reasonable progress goal requirements. As discussed above and in our 
comments submitted to DEQ, the alternative compliance agreements will 
achieve far fewer reductions in visibility-impairing pollution than the 
controls identified in the 2021 control letters. As a result, Oregon's 
reasonable progress goals are not reflective of the visibility 
improvements that the long-term strategy controls will achieve, in 
violation of the Regional Haze Rule.''
    Response: We disagree with this comment. Oregon's reasonable 
progress goals meet the requirements of 40 CFR 51.308(f)(3). We note 
initially that Oregon has made significant progress reducing regional 
haze, as shown in table 6 of this preamble. In section IV.F of our 
proposed rulemaking we addressed the reasonable progress goals (RPG). 
We described the major factors that will continue to reduce regional 
haze precursor emissions during the 2018-2028 implementation period. We 
highlighted Oregon's mobile source regulations, because mobile sources 
account for approximately 80% of the statewide NO<INF>X</INF> emissions 
inventory.\130\ We also highlighted the impact of international marine 
shipping and how these emissions (SO<INF>2</INF>) are projected to 
decrease by 77% due to new standards for international marine shipping 
fuels which became effective in 2020.\131\ With respect to stationary 
sources we acknowledged the significant SO<INF>2</INF> reductions from 
the closure of Boardman facility (the only coal-fired electric 
generating unit in the state).

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

    Like other western states, Oregon used modeling from the Western 
Regional Air Partnership (WRAP) to conduct RPG modeling. This included 
`Future Year 2028 with On the Books Controls'' which forecasted 
expected reductions from the Boardman facility

[[Page 81380]]

as well as anticipated mobile source reductions. The WRAP also modeled 
``Future Year 2028 with Potential Additional Controls.'' Due to time 
constraints in analyzing and assessing final four-factor 
determinations, these RPG calculations were based on ODEQ's January 
2021 preliminary determinations. However, as noted in our proposed 
rulemaking we explained that in considering the dominance of the mobile 
source and international marine shipping emissions source categories on 
the overall inventory, it is unlikely that differences in the 
stationary source controls selected by Oregon would significantly 
impact the projected RPG modeling for the monitoring stations 
associated with the respective Class I areas.\132\ This is borne out by 
the data in table 6, drawn from publicly available information.\133\ 
The average difference between the ``Future Year 2028 with On the Books 
Controls'' and the ``Future Year 2028 with Potential Additional 
Controls'' RPG projections is 0.03 deciview for the six Oregon regional 
haze monitoring sites. The claim that RPGs will be significantly 
divergent because of the difference between the January 2021 
preliminary determinations and the August 2021 final four-factor 
determinations does not consider the overall emission source mix, 
particularly for NOx which is dominated by mobile source emissions that 
are driving the significant reductions predicted between 2018 and 2028 
(approximately 80% of the 2017 inventory). Therefore, we do not believe 
there is adequate basis to disapprove Oregon's use of the January 2021 
preliminary determinations in projecting RPG because the August 2021 
final determinations were not yet available when WRAP conducted its 
modeling.

the on the books plus additional measures calculation, which differs 
slightly from the RPGs reported by Oregon and listed in our proposed 
rulemaking.

8. Robust Demonstration Requirements
    Comment: ``EPA's claim that Oregon satisfied the ``robust 
demonstration'' requirement is also incorrect. EPA explains that the 
reasonable progress goals for eight of Oregon's 12 Class I areas are 
projected to be above their 2028 unadjusted uniform rate of progress 
glidepath, triggering the Regional Haze Rule's ``robust demonstration'' 
requirement. EPA's conclusion that Oregon satisfied this requirement 
for the same flawed reasons it satisfied its long-term strategy 
requirements fails for two reasons. First, because Oregon's reasonable 
progress goals are based on incorrect assumptions about the emissions-
reducing control measures that screened-in sources would install, the 
reasonable progress goals for these Class I areas are likely even 
further above the 2028 uniform rate of progress than the SIP Revision 
reflects. And there is nothing in the record to demonstrate that the 
alternative compliance measures Oregon offered to sources would provide 
emission reductions that are equivalent to the controls identified in 
the 2021 letters.
    Second, there are readily available, feasible, and cost-effective 
controls for multiple sources that Oregon failed to include in the SIP 
Revision as necessary to make reasonable progress--namely, those 
identified in the 2021 control letters that were not included in the 
alternative compliance agreements. As long as there are other feasible 
and cost-effective controls available that are not included in the SIP 
Revision, Oregon cannot satisfy its robust demonstration requirement.''
    Response: We disagree with this comment. According to WRAP modeling 
data \134\ analyzed by the EPA, 4 of the 6 Oregon regional haze 
monitoring sites have ``Future Year 2028 with On the Books Controls'' 
with projections below the 2028 uniform rate of progress as shown in 
table 6.\135\ These are the emissions reductions that are already 
predicted to occur, primarily due to the closure of the Boardman 
facility and Oregon's aggressive mobile source regulations. These 
projections do not include the controls listed in Oregon's January 2021 
``Preliminary Determination of Cost Effective Controls for Regional 
Haze'' letters. The two remaining monitors, THSI (representing Mt. 
Jefferson, Mt. Washington, and Three Sisters Wilderness Areas) and KALM 
(representing the Kalmiopsis Wilderness Area), have ``Future Year 2028 
with On the Books Controls'' projections marginally above the 2028 
unadjusted glidepath but well below the EPA's 2028 default adjusted 
glidepath to account for international emissions.\136\

Support Document for the EPA's Updated 2028 Visibility Air Quality 
Modeling, September 2019.
---------------------------------------------------------------------------

    As noted by the Environmental Organizations, Oregon chose not to 
adjust the glidepath to account for international contribution. 
However, as we discussed in the proposal, it is reasonable for the EPA 
to consider our own modeling information in evaluating the Oregon SIP. 
The EPA's modeling data appears to corroborate Oregon's assessment that 
these monitors are significantly impacted by amonium sulfate from 
international marine shipping.\137\ This assessment is further 
corroborated by the EPA's review of Chapter 2.4 Pollutant Components of 
Visibility Impairment, of Oregon's 2022

[[Page 81381]]

SIP submission. These graphs highlight the stark difference in ammonium 
sulfate contribution between regional haze monitors in eastern Oregon 
compared to southern coastal and central Oregon monitors more likely to 
be impacted by international marine shipping. The only stationary 
source with significant SO<INF>2</INF> emissions was the now closed 
Boardman facility; however, this facility was located far to the 
northeast and is unlikely to have impacted the two affected monitors 
along the southeastern Oregon coast and central cascades region. This 
lends further credence to Oregon's determination that these monitors 
were impacted by international marine shipping.
---------------------------------------------------------------------------

    \137\ See April 22, 2022 Oregon regional haze SIP at page 17.
---------------------------------------------------------------------------

    EPA included this data assessment in the proposal. The commenters 
did not demonstrate that EPA's assessment of the data is flawed. 
Rather, the commenters assume without supporting data the RPGs ought to 
be higher because Oregon's long-term strategy (LTS) does not include 
all the controls initially included in the model used to set the RPGs. 
However, the EPA's assessment refutes this assumption. On-the-books 
controls and international shipping are the dominant drivers for 
Oregon's reasonable progress goals. Given this, Oregon's RPGs reflect 
the visibility conditions that are projected to be achieved by the end 
of 2028 as required by 40 CFR 51.308(f)(2).
    With respect to the Environmental Organizations' broader statement 
that Oregon did not meet the robust demonstration requirements because 
``other feasible and cost-effective controls available that are not 
included in the SIP Revision,'' we disagree. Attachment A of the 
Environmental Organizations' comments includes a comparison of the 
proposed controls in ODEQ's January 2021 ``Preliminary Determination of 
Cost Effective Controls for Regional Haze'' letters to the final 
control determinations as proof that feasible cost-effective controls 
were available. We do not agree with this argument for two reasons.
    First, as described in sections II.B.4 and II.B.5 of this preamble, 
the preliminary control determination letters are not four-factor 
analyses. The four-factor analyses are the documents submitted pursuant 
to OAR 340-223-0110(1) which ODEQ reviewed and analyzed under OAR 340-
223-0120, both before and after January 2021 in making final four-
factor determinations. Second, and more importantly, in section 5 of 
Oregon's 2023 supplement, ODEQ provided a summary of the rationale the 
agency used in making final control determinations based on ODEQ's 
review the four-factor analyses and all relevant correspondence with 
the facilities regarding the four-factor analyses (appendices 1 through 
6). This information was added to the 2023 supplement specifically to 
address concerns voiced by NPS and Environmental Organizations that the 
2022 regional haze SIP did not contain adequate information to explain 
the difference between the preliminary determinations and ODEQ's final 
control determinations. Neither the Environmental Organizations' 
comments, nor the attachments, cite to, reference, or analyse this 
critical information. Therefore, we do not see a basis to claim that 
other feasible and cost-effective controls were available when there is 
no record to suggest the Environmental Organizations considered the 
correspondence regarding the final four-factor determinations.
9. Environmental Justice
    Comment: The Environmental Organizations submitted lengthy comments 
regarding environmental justice, which are available in the docket for 
this action. In summary, the Environmental Organizations commented that 
(1) EPA is required under Executive Orders and EPA's own commitments to 
consider environmental justice and (2) EPA ignores the environmental 
justice impacts of Oregon's Regional Haze SIPs.
    Response: The regional haze statutory provisions do not explicitly 
address considerations of environmental justice, and neither do the 
regulatory requirements of the second planning period in 40 CFR 
51.308(f), (g), and (i). However, the lack of explicit direction does 
not preclude the State from addressing EJ in the State's SIP 
submission. As explained in ``EPA Legal Tools to Advance Environmental 
Justice,'' \138\ the CAA provides states with the discretion to 
consider environmental justice in developing rules and measures related 
to regional haze.
---------------------------------------------------------------------------

    \138\ See EPA Legal Tools to Advance Environmental Justice, May 
2022, available at www.epa.gov/system/files/documents/2022-05/EJ%20Legal%20Tools%20May%202022%20FINAL.pdf at 35-36.
---------------------------------------------------------------------------

    In this instance Oregon included an entire chapter, 3.6.1 
Environmental Justice Analysis, ``[t]o better understand the potential 
co-benefits of pollutant controls, DEQ undertook an environmental 
justice analysis of communities surrounding the facilities that DEQ's 
Regional Haze decisions will affect.'' \139\ This chapter provided 
additional information from EJ Screen to calculate a ``Vulnerable 
Populations Score'' and a ``Environmental Justice Score Methodology for 
Oregon'' which helped inform the overall weight of evidence approach 
which led ODEQ to conclude, ``that controls are both environmentally 
beneficial and cost effective at many facilities evaluated by DEQ.''

III. Final Action

    For the reasons stated in our proposed action (89 FR 13622, 
February 23, 2024) and in section II. of this preamble, we are 
approving the Oregon SIP revision submitted on April 29, 2022, as 
supplemented on November 22, 2023, as satisfying the regional haze 
requirements for the second implementation period contained in 40 CFR 
51.308.
    The EPA is approving and incorporating by reference in 40 CFR 
52.1970(c), Table 2--EPA Approved Oregon Administrative Rules (OAR) the 
following updates to Division 223 Regional Haze Rules, state effective 
July 26, 2021:
    <bullet> 340-223-0010 Purpose, for maintaining reasonable progress 
and other requirements associated with Oregon's implementation of the 
Federal Regional Haze Rule;
    <bullet> 340-223-0020 Definitions, updating this section to account 
for revised program requirements between the first regional haze 
implementation period and the second implementation period;

Administrative Rules (OAR) the outdated provisions from the first 
regional haze implementation period contained in sections 340-223-0030,

IV. Incorporation by Reference

    In this document, the EPA is finalizing regulatory text that 
includes incorporation by reference. In accordance with requirements of 
1 CFR 51.5, we are finalizing the incorporation by reference of the 
Oregon regulatory and source-specific provisions described in section 
III. of this preamble and set forth in the amendments to 40 CFR part 52 
in this document. The EPA has made, and will continue to make, these 
materials generally available through https://www.regulations.gov and 
at the EPA Region 10 Office (please contact the person identified in 
the FOR FURTHER INFORMATION CONTACT section of this preamble for more 
information). Therefore, these materials have been approved by the EPA 
for inclusion in the SIP, have been incorporated by reference by the 
EPA into that plan, are fully federally enforceable under sections 110 
and 113 of the Clean Air Act as of the effective date of the final rule 
of the EPA's approval, and will be incorporated by reference in the 
next update to the SIP compilation.\141\
---------------------------------------------------------------------------

    \141\ 62 FR 27968 (May 22, 1997).
---------------------------------------------------------------------------

    Also in this document, the EPA is removing regulatory text from 
incorporated by reference, as described in section III. of this 
preamble.

V. Statutory and Executive Order Reviews

    Under the Clean Air Act, the Administrator is required to approve a 
SIP submission that complies with the provisions of the Clean Air Act 
and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). 
Thus, in reviewing SIP submissions, the EPA's role is to approve state 
choices, provided that they meet the criteria of the Clean Air Act. 
Accordingly, this action merely approves state law as meeting Federal 
requirements and does not impose additional requirements beyond those 
imposed by state law. For that reason, this action:
    <bullet> Is not a significant regulatory action subject to review 
by the Office of Management and Budget under Executive Orders 12866 (58 
FR 51735, October 4, 1993) and 14094 (88 FR 21879, April 11, 2023);
    <bullet> Does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
    <bullet> Is certified as not having a significant economic impact 
on a substantial number of small entities under the Regulatory 
Flexibility Act (5 U.S.C. 601 et seq.);
    <bullet> Does not contain any unfunded mandate or significantly or 
uniquely affect small governments, as described in the Unfunded 
Mandates Reform Act of 1995 (Pub. L. 104-4);
    <bullet> Does not have federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999);
    <bullet> Is not subject to Executive Order 13045 (62 FR 19885, 
April 23, 1997) because it approves a state program;
    <bullet> Is not a significant regulatory action subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001); and
    <bullet> Is not subject to requirements of Section 12(d) of the 
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 
note) because application of those requirements would be inconsistent 
with the Clean Air Act.
    Executive Order 12898 (Federal Actions to Address Environmental 
Justice in Minority Populations and Low-Income Populations, 59 FR 7629, 
February 16, 1994) directs Federal agencies to identify and address 
``disproportionately high and adverse human health or environmental 
effects'' of their actions on communities with environmental justice 
(EJ) concerns to the greatest extent practicable and permitted by law. 
The EPA defines EJ as ``the fair treatment and meaningful involvement 
of all people regardless of race, color, national origin, or income 
with respect to the development, implementation, and enforcement of 
environmental laws, regulations, and policies.'' The EPA further 
defines the term fair treatment to mean that ``no group of people 
should bear a disproportionate burden of environmental harms and risks, 
including those resulting from the negative environmental consequences 
of industrial, governmental, and commercial operations or programs and 
policies.'' The Oregon Department of Environmental Quality did evaluate 
environmental justice considerations as part of its SIP submittal; the 
CAA and applicable implementing regulations neither prohibit nor 
require such an evaluation. The EPA did not perform an EJ analysis and 
did not consider EJ in this action. Consideration of EJ is not required 
as part of this action, and there is no information in the record 
inconsistent with the stated goal of Executive Order 12898 of achieving 
environmental justice for communities with EJ concerns.
    In addition, the SIP is not approved to apply on any Indian 
reservation land or in any other area where the EPA or an Indian Tribe 
has demonstrated that a Tribe has jurisdiction. In those areas of 
Indian country, the rule does not have Tribal implications and it will 
not impose substantial direct costs on Tribal governments or preempt 
Tribal law as specified by Executive Order 13175 (65 FR 67249, November 
9, 2000).
    This action is subject to the Congressional Review Act, 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).
    Under section 307(b)(1) of the Clean Air Act, petitions for 
judicial review of this action must be filed in the United States Court 
of Appeals for the appropriate circuit by December 9, 2024. Filing a 
petition for reconsideration by the Administrator of this final rule 
does not affect the finality of this action for the purposes of 
judicial review nor does it extend the time within which a petition for 
judicial review may be filed and shall not postpone the effectiveness 
of such rule or action. This action may not be challenged later in 
proceedings to enforce its requirements. See section 307(b)(2).
