Air Plan Revisions; California; Yolo-Solano Air Quality 
Management District

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing to 
partially approve and partially disapprove, under the Clean Air Act 
(CAA or ``Act''), a revision to the California state implementation 
plan (SIP). This revision addresses reasonably available control 
technology (RACT) requirements for the 2008 8-hour ozone national 
ambient air quality standards (NAAQS or ``standards'') in the portion 
of the Sacramento Metropolitan nonattainment area that is subject to 
the jurisdiction of the Yolo-Solano Air Quality Management District 
(YSAQMD). We are taking comments on this proposal and plan to follow 
with a final action.

DATES: Comments must be received on or before May 11, 2023.

B. Are there other versions of this document?

    There are no other versions of this document, but we previously 
took final action to approve the negative declarations from the 2017 
RACT SIP.\3\ The remaining elements of the 2017 RACT SIP are the 
subject of this action.
---------------------------------------------------------------------------

    \3\ 83 FR 31017 (April 5, 2018). This action also approved four 
additional negative declarations submitted by the YSAQMD on February 
22, 2018.
---------------------------------------------------------------------------

C. What is the purpose of the submitted document?

    Emissions of volatile organic compounds (VOCs) and oxides of 
nitrogen (NOX) contribute to the production of ground-level 
ozone, smog and particulate matter (PM), which harm human health and 
the environment. Section 110(a) of the CAA requires states to submit 
regulations that control VOC and NOX emissions. Sections 
182(b)(2) and (f) require that SIPs for ozone nonattainment areas 
classified as Moderate or above implement RACT for any source covered 
by a Control Techniques Guidelines (CTG) document and for any major 
source of VOCs or NOX. The YSAQMD is subject to this 
requirement as it regulates the Yolo County and Solano County portions 
of the Sacramento Metropolitan ozone nonattainment area that is 
classified as a Severe nonattainment area for the 2008 8-hour ozone 
NAAQS.\4\ Therefore, the YSAQMD must, at a minimum, adopt RACT-level 
controls for all sources covered by a CTG document and for all major 
non-CTG sources of VOCs or NOX within the portion of the 
ozone nonattainment area that it regulates. Any stationary source that 
emits or has the potential to emit at least 25 tons per year (tpy) of 
VOCs or NOX is a major stationary source in a Severe ozone 
nonattainment area.\5\

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

    Section III.D of the preamble to the EPA's final rule to implement 
the 2008 ozone NAAQS discusses RACT requirements.\6\ It states, in 
part, that RACT SIPs must contain adopted RACT regulations, 
certifications (where appropriate) that existing provisions are RACT, 
and/or negative declarations that no sources in the nonattainment area 
are covered by a specific CTG.\7\ It also provides that states must 
submit appropriate supporting information for their RACT submissions as 
described in the EPA's implementation rule for the 1997 ozone NAAQS.\8\ 
The 2017 RACT SIP submittal and negative declarations provide the 
YSAQMD's analyses of its compliance with the CAA section 182 RACT 
requirements for the 2008 8-hour ozone NAAQS.

II. The EPA's Evaluation and Action

A. How is the EPA evaluating the submitted document?

    Generally, SIP rules must require RACT for all sources covered by a 
CTG document as well as each major source of VOCs or NOX in 
ozone nonattainment areas classified as Moderate or above.\11\ The 
YSAQMD regulates the Yolo County and Solano County portions of the 
Sacramento Metropolitan ozone nonattainment area, which is classified 
as Severe for the 2008 ozone standard (40 CFR 81.305). Therefore, 
YSAQMD rules must implement RACT.
---------------------------------------------------------------------------

    \11\ CAA section 182(b)(2), (f).
---------------------------------------------------------------------------

    States should also submit for SIP approval negative declarations 
for those CTGs for which they have no sources covered by the CTG, 
regardless of whether such negative declarations were made in a SIP 
submittal for an earlier ozone standard.\12\ To do so, the submittal 
should provide reasonable assurances that no sources that fall under 
the CTG currently exist in the regulated area.
---------------------------------------------------------------------------

    \12\ 57 FR 13498, 13512 (April 16, 1992).
---------------------------------------------------------------------------

    Accordingly, the District's analysis must demonstrate that each 
major source of VOCs or NOX in the ozone nonattainment area 
is covered by a RACT-level rule. In addition, for each CTG, the 
District must either demonstrate that a RACT-level rule is in place or 
submit a negative declaration. Guidance and policy documents that we 
use to evaluate CAA section 182 RACT requirements include the 
following:

Implementation of Title I of the Clean Air Act Amendments of 1990,'' 57

B. Does the document meet the evaluation criteria?

    The 2017 RACT SIP concludes that the YSAQMD has satisfied CAA 
section 182 RACT requirements for the 2008 8-hour ozone NAAQS, based on 
an analysis of SIP-approved requirements that apply to sources covered 
by a CTG, and major non-CTG stationary sources of VOC or NOX 
emissions.
    With respect to CTG sources, the 2017 RACT SIP identifies several 
CTGs with covered sources (i.e., sources covered by the CTG and 
operating within the nonattainment area), and provides an evaluation of 
the rules that the District relies upon to meet RACT for these CTGs. We 
reviewed the District's evaluation and agree that its rules implement 
RACT for the applicable CTGs. Our TSD has additional information about 
our evaluation of these rules.

[[Page 21574]]

    Table 3 of the 2017 RACT SIP lists the YSAQMD's negative 
declarations where there are no sources in the District subject to the 
applicable CTGs for the 2008 8-hour ozone NAAQS. We previously approved 
the District's negative declarations on April 5, 2018,\13\ and while 
they are not the subject of this action, we have summarized these 
negative declarations with the remaining RACT elements for the 2008 
ozone NAAQS in Table 2 below.
---------------------------------------------------------------------------

    \13\ 83 FR 31017.
---------------------------------------------------------------------------

    With respect to non-CTG major sources of NOX or VOC, 
YSAQMD identified nine facilities exceeding the major source threshold 
for NOX or VOC, which is 25 tpy in Severe ozone 
nonattainment areas. As described in more detail in our TSD, we 
conclude that YSAQMD properly identified all major non-CTG sources of 
NOX or VOC requiring RACT. YSAQMD also identified several 
district rules, including several NOX rules, that it relies 
upon to implement RACT at these major sources. As discussed in more 
detail in Section II.C below, we have noted deficiencies in two of the 
identified district rules, and conclude that these district rules do 
not fully satisfy the RACT requirement.

C. What are the deficiencies?

    YSAQMD has identified Rule 2.38 (Standards for Municipal Solid 
Waste Landfills) as implementing RACT for several municipal solid waste 
landfills in the District that are non-CTG major sources of VOC. 
Although Rule 2.38 is in effect locally, it has not been submitted for 
approval into the SIP. Because Rule 2.38 is not federally enforceable 
through the SIP, it cannot be used to satisfy RACT requirements.\14\ 
This deficiency represents the basis for our partial disapproval of the 
2017 RACT SIP for the non-CTG major source VOC RACT element. The 
District may remedy this deficiency by submitting an approvable rule 
that implements RACT for municipal solid waste landfills that are non-
CTG major sources. See Section 6.1 of the TSD for more information.
---------------------------------------------------------------------------

    \14\ See CAA section 110(a)(2)(A) (requiring SIPs to include 
enforceable emission limitations and other control measures, means, 
or techniques as necessary to meet CAA requirements).
---------------------------------------------------------------------------

    Rule 2.43 (Biomass Boilers), which is relied upon to implement RACT 
for the non-CTG major source NOX element, is inconsistent 
with the EPA's SSM Policy because it exempts affected units from 
complying with rule standards during periods of startup and shutdown 
and does not provide any alternative emissions limitation during such 
periods. The EPA's SSM policy, as defined in the 2015 SSM SIP 
Action,\15\ explains that an emission limitation or requirement that 
exempts periods of source operation, such as startup, cannot be 
considered ``continuous'' and is therefore inconsistent with the 
definition of ``emission limitation'' at CAA section 302(k). Under this 
definition, an emission limitation must limit ``the quantity, rate, or 
concentration of emissions of air pollution on a continuous basis'' 
(absent an alternative emission limitation that applies during such 
periods). Since Rule 2.43 includes an exemption to emission standards 
during periods of startup and shutdown, it does not apply on a 
continuous basis; thus, it does not implement RACT during all operating 
conditions, regardless of the level of stringency that the Rule 2.43 
standards establish outside of exempt periods. This deficiency 
represents the basis for our partial disapproval of the 2017 RACT SIP 
for the non-CTG major source NOX RACT element. The District 
may remedy this deficiency by establishing a continuous emission limit 
that applies at all times, including during startup and shutdown. See 
Section 6.2 of the TSD for more information.
---------------------------------------------------------------------------

    \15\ 80 FR 33839 (June 12, 2015).
---------------------------------------------------------------------------

D. Proposed Action and Public Comment

    For the reasons discussed above and explained in more detail in our 
TSD, the EPA proposes to partially approve and partially disapprove the 
2017 RACT SIP. As authorized in section 110(k)(3) of the Act, we are 
proposing to approve the 2017 RACT SIP for each of the CTGs addressed 
by a District rule. Also under section 110(k)(3), we propose to 
disapprove the 2017 RACT SIP as it pertains to the non-CTG major source 
NOX and VOC RACT elements, based upon our conclusion that 
two of the District rules relied upon to implement RACT for these 
elements contain deficiencies that preclude them from implementing 
RACT. Table 2 lists each RACT element, the District rule or negative 
declaration relied upon to address RACT, and our proposed action for 
that RACT element.
    The EPA is committed to working with YSAQMD to resolve the 
identified RACT deficiencies. However, should we finalize the proposed 
partial disapproval of the non-CTG major source NOX and VOC 
RACT elements of the 2017 RACT SIP, CAA section 110(c) would require 
the EPA to promulgate a federal implementation plan (FIP) within 24 
months unless we approve subsequent SIP revisions that correct the 
deficiencies identified in our final action. In this instance, we note 
that the EPA already has an existing obligation to promulgate a FIP for 
any RACT SIP elements that we have not taken final action to approve. 
This FIP obligation originates from our February 3, 2017 finding that 
YSAQMD failed to submit a RACT SIP for the 2008 8-hour ozone NAAQS by 
the required submittal deadline.\16\ This finding of failure to submit 
established a FIP obligation deadline of February 3, 2019.
---------------------------------------------------------------------------

    \16\ 82 FR 9158.
---------------------------------------------------------------------------

    In addition, final action on the proposed partial disapproval would 
trigger the offset sanction in CAA section 179(b)(2) 18 months after 
the effective date of a final disapproval, and the highway funding 
sanction in CAA section 179(b)(1) six months after the offset sanction 
is imposed. A sanction will not be imposed if the EPA determines that a 
subsequent SIP submission corrects the deficiencies identified in our 
final action before the applicable deadline.\17\
---------------------------------------------------------------------------

    \17\ Our February 7, 2017 finding of failure to submit also 
triggered offset sanctions and highway funding sanctions. These 
sanctions clocks were extinguished by the YSAQMD's submittal of its 
2017 RACT SIP and our April 11, 2018 and August 23, 2018 letters 
determining that the District's RACT SIP submittal was complete.
---------------------------------------------------------------------------

    We will accept comments from the public on this proposed partial 
approval and partial disapproval until May 11, 2023. If finalized, this 
action would incorporate the approved portions of the 2017 RACT SIP 
into the SIP.

III. Statutory and Executive Order Reviews

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

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

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

B. Paperwork Reduction Act (PRA)

    This action does not impose an information collection burden under 
the PRA because this action does not impose additional requirements 
beyond those imposed by state law.

C. Regulatory Flexibility Act (RFA)

    I certify that this action will not have a significant economic 
impact on a substantial number of small entities under the RFA. This 
action will not impose any requirements on small entities beyond those 
imposed by state law.

D. Unfunded Mandates Reform Act (UMRA)

    This action does not contain any unfunded mandate as described in 
UMRA, 2 U.S.C. 1531-1538, and does not significantly or uniquely affect 
small governments. This action does not impose additional requirements 
beyond those imposed by state law. Accordingly, no additional costs to 
state, local, or tribal governments, or to the private sector, will 
result from this action.

E. Executive Order 13132: Federalism

    This action does not have federalism implications. It will not have 
substantial direct effects on the states, on the relationship between 
the national government and the states, or on the distribution of power 
and responsibilities among the various levels of government.

F. Executive Order 13175: Coordination With Indian Tribal Governments

    This action does not have tribal implications, as specified in 
Executive Order 13175, because 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, and will not 
impose substantial direct costs on tribal governments or preempt tribal 
law. Thus, Executive Order 13175 does not apply to this action.

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

    The EPA interprets Executive Order 13045 as applying only to those 
regulatory actions that concern environmental health or safety risks 
that the EPA has reason to believe may disproportionately affect 
children, per the definition of ``covered regulatory action'' in 
section 2-202 of the Executive Order. This action is not subject to 
Executive Order 13045 because it does not impose additional 
requirements beyond those imposed by state law.

H. Executive Order 13211: Actions That Significantly Affect Energy 
Supply, Distribution, or Use

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

I. National Technology Transfer and Advancement Act (NTTAA)

    Section 12(d) of the NTTAA directs the EPA to use voluntary 
consensus standards in its regulatory activities unless to do so would 
be inconsistent with applicable law or otherwise impractical. The EPA 
believes that this action is not subject to the requirements of section 
12(d) of the NTTAA because application of those requirements would be 
inconsistent with the CAA.

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

    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 minority populations and low-income 
populations to the greatest extent practicable and permitted by law. 
The EPA defines environmental justice (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.''
    Under the CAA, the Administrator is required to approve a SIP 
submission that complies with the provision of the Act and applicable 
federal regulations. 42 U.S.C. 740(k); 40 CFR 52.02(a). Thus, in 
reviewing SIP submissions, the EPA's role is to review state choices, 
and approve those choices if they meet the minimum criteria of the Act. 
Accordingly, this proposed action partially approves and partially 
disapproves state law as meeting federal requirements and does not 
impose additional requirements beyond those imposed by state law.
    The District did not 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 goals of 
Executive Order 12898 of achieving environmental justice for people of 
color, low-income populations, and indigenous peoples.
