Air Plan Approval; Missouri; Removal of Control of Emissions From 
Manufacture of Polystyrene Resin

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing 
approval of a State Implementation Plan (SIP) revision submitted by the 
State of Missouri on January 15, 2019, and supplemented by letter on 
July 11, 2019. Missouri requests that the EPA remove a rule related to 
the control of emissions from the manufacture of polystyrene resin in 
the St. Louis, Missouri area from its SIP. This removal does not have 
an adverse effect on air quality. The EPA's proposed approval of this 
rule revision is in accordance with the requirements of the Clean Air 
Act (CAA).

II. What is being addressed in this document?

    The EPA is proposing to approve the removal of 10 Code of State 
Regulations (CSR) 10-5.410, Control of Emissions from Manufacture of 
Polystyrene Resin, from the Missouri SIP.
    According to the July 11, 2019 letter from the Missouri Department 
of Natural Resources, available in the docket for this proposed action, 
Missouri rescinded the rule because the only source subject to the rule 
ceased manufacturing polystyrene resin in 2009,\1\ and the rule is no 
longer necessary for attainment and maintenance of the 1979, 1997, 
2008, or 2015 National Ambient Air Quality Standards (NAAQS) for Ozone.
---------------------------------------------------------------------------

    \1\ The Part 70 Permit to Operate issued by Missouri to The Dow 
Chemical Company, Riverside Plant on September 22, 2010 describes 
the specific emissions units that ceased operation and the date the 
cessation occurred.
---------------------------------------------------------------------------

III. Background

    The EPA established a 1-hour ozone NAAQS in 1971. 36 FR 8186 (April 
30, 1971). On March 3, 1978, the entire St. Louis Air Quality Control 
Region (AQCR) (070) was identified as being in nonattainment of the 
1971 1-hour ozone NAAQS, as required by the CAA Amendments of 1977. 43 
FR 8962

[[Page 43527]]

(March 3, 1978). On the Missouri side, the St. Louis nonattainment area 
included the city of St. Louis and Jefferson, St. Charles, Franklin and 
St. Louis Counties (hereinafter referred to in this document as the 
``St. Louis Area''). On February 8, 1979, the EPA revised the 1-hour 
ozone NAAQS, referred to as the 1979 ozone NAAQS. 44 FR 8202 (February 
8, 1979). On May 26, 1988, the EPA notified Missouri that the SIP was 
substantially inadequate (hereinafter referred to as the ``SIP Call'') 
to attain the 1-hour ozone NAAQS in the St. Louis Area. See 54 FR 43183 
(October 23, 1989).
    To address the inadequacies identified in the SIP Call, Missouri 
submitted volatile organic compound (VOC) control regulations on June 
14, 1985; November 19, 1986; and March 30, 1989. The EPA subsequently 
approved the revised control regulations for the St. Louis Area on 
March 5, 1990. The VOC control regulations approved by EPA into the SIP 
included reasonably available control technology (RACT) rules as 
required by CAA section 172(b)(2), including 10 CSR 10-5.410 Control of 
Emissions from Manufacture of Polystyrene Resin.
    The EPA redesignated the St. Louis Area to attainment of the 1979 
1-hour ozone standard on May 12, 2003. 68 FR 25418. Pursuant to section 
175A of the CAA, the first 10-year maintenance period for the 1-hour 
ozone standard began on May 12, 2003, the effective date of the 
redesignation approval. On April 30, 2004, the EPA published a final 
rule in the Federal Register stating the 1-hour ozone NAAQS would no 
longer apply (i.e., would be revoked) for an area one year after the 
effective date of the area's designation for the 8-hour ozone NAAQS. 69 
FR 23951 (April 30, 2004). The effective date of the revocation of the 
1979 1-hour ozone standard for the St. Louis Area was June 15, 2005. 
See 70 FR 44470 (August 3, 2005).
    As noted above, 10 CSR 10-5.410, Control of Emissions from 
Manufacture of Polystyrene Resin, was approved into the Missouri SIP as 
a RACT rule on March 5, 1990. 55 FR 7712 (March 5, 1990). At the time 
that the rule was approved into the SIP, 10 CSR 10-5.410 applied to all 
installations throughout St. Louis City and Jefferson, St. Charles, 
Franklin and St. Louis Counties that manufactured polystyrene resin.
    By letter dated January 15, 2019, Missouri requested that the EPA 
remove 10 CSR 10-5.410 from the SIP. Section 110(l) of the CAA 
prohibits EPA from approving a SIP revision that interferes with any 
applicable requirement concerning attainment and reasonable further 
progress (RFP), or any other applicable requirement of the CAA. The 
State supplemented its SIP revision with a July 11, 2019 letter in 
order to address the requirements of section 110(l) of the CAA.

IV. What is the EPA's analysis of Missouri's SIP revision request?

    In its July 11, 2019 letter, Missouri states that it intended its 
RACT rules, such as 10 CSR 10-5.410, to solely apply to existing 
sources in accordance with section 172(c)(1) of the CAA.\2\ Missouri 
states that although the applicability section of 10 CSR 10-5.410 
specifies that the rule applies to all installations located throughout 
St. Louis City and Jefferson, St. Charles, Franklin and St. Louis 
Counties, the only facility that met the applicability criteria of the 
rule was The Dow Chemical Company, Riverside Plant (hereinafter 
referred to as ``Dow Chemical'').
---------------------------------------------------------------------------

    \2\ The EPA agrees with Missouri's interpretation of CAA section 
172(c)(1) in regard to whether RACT is required for existing 
sources, but also notes that the State regulation establishing RACT 
may apply to new sources as well, dependent upon the State 
regulation's language.
---------------------------------------------------------------------------

    Missouri, in its July 11, 2019 letter, indicated that Dow Chemical 
no longer manufactures polystyrene resin and instead purchases all the 
polystyrene resin used at the facility.\3\ Dow Chemical discontinued 
the manufacture of polystyrene resin in 2009. The EPA confirmed that 
the facility is no longer manufacturing polystyrene resin \4\ and is 
therefore no longer subject to 10 CSR 10-5.410.
---------------------------------------------------------------------------

    \3\ This change in the operation of the facility is supported by 
the Title V Permit issued on September 22, 2010 to Dow Chemical. The 
September 22, 2010 Title V Permit includes a statement that the 
polystyrene resin manufacturing emissions units were removed from 
operations and the Title V Permit.
    \4\ EPA reviewed the September 22, 2010 and the April 13, 2017 
Title V Permits issued to Dow Chemical and the March 5, 2019 MDNR 
inspection report of Dow Chemical, currently operating as DDP 
Specialty Electronic Materials US Inc. and confirmed that these 
emissions units were no longer used.
---------------------------------------------------------------------------

    As stated above, Missouri contends that 10 CSR 10-5.410 may be 
removed from the SIP because section 172(c)(1) of the CAA requires RACT 
for existing sources, and because 10 CSR 10-5.410 was applicable to a 
single source that has ceased the operations that caused the facility 
to meet the applicability criteria of the rule and, therefore, the rule 
no longer reduces VOC emissions. Because Dow Chemical was the only 
source subject to the rule, and because the facility ceased the 
manufacture of polystyrene resin in 2009, the EPA believes the rule no 
longer provides an emission reduction benefit to the St. Louis Area and 
is proposing to remove it from the SIP.
    Missouri's July 11, 2019 letter states that any new sources or 
major modifications of existing sources are subject to new source 
review (NSR) permitting. Under NSR, a new major source or major 
modification of an existing source with a (potential to emit) PTE of 
250 tons per year (tpy) \5\ or more of any NAAQS pollutant is required 
to obtain a Prevention of Significant Deterioration (PSD) permit when 
the area is in attainment or unclassifiable, which requires an analysis 
of Best Available Control Technology (BACT) in addition to an air 
quality analysis and an additional impacts analysis. Sources with a PTE 
greater than 100 tpy, but less than 250 tpy,\6\ are required to obtain 
a minor permit in accordance with Missouri's New Source Review 
permitting program, which is approved into the SIP.\7\ Further, a new 
major source or major modification of an existing source with a PTE of 
100 tpy or more of any NAAQS pollutant is required to obtain a 
nonattainment (NA) NSR permit when the area is in nonattainment, which 
requires an analysis of Lowest Achievable Emission Rate (LAER) in 
addition to an air quality analysis, an additional impacts analysis and 
emission offsets. The EPA agrees with this analysis.
---------------------------------------------------------------------------

    \5\ The PSD major source threshold for certain sources is 100 
tpy rather than 250 tpy (see 40 CFR 52.21(b)(1)(i)(a) and 10 C.S.R. 
10-6.060(8)(A)).
    \6\ Except for those sources with a PSD major source threshold 
of 100 tpy.
    \7\ EPA's latest approval of Missouri's NSR permitting program 
rule was published in the Federal Register on October 11, 2016. 81 
FR 70025.
---------------------------------------------------------------------------

    Missouri has demonstrated that removal of 10 CSR 10-5.410 will not 
interfere with attainment of the NAAQS, RFP \8\ or any other applicable 
requirement of the CAA because the single source subject to the rule 
has ceased the manufacture of polystyrene resin and the removal of the 
rule will not cause VOC emissions to increase. Therefore, the EPA 
proposes to approve the removal of 10 CSR 10-5.410 from the SIP.
---------------------------------------------------------------------------

    \8\ RFP is not applicable to the St. Louis Area because for 
marginal ozone nonattainment areas, such as the St. Louis Area, the 
specific requirements of section 182(a) apply in lieu of the 
attainment planning requirements that would otherwise apply under 
section 172(c), including the attainment demonstration and 
reasonably available control measures (RACM) under section 
172(c)(1), reasonable further progress (RFP) under section 
172(c)(2), and contingency measures under section 172(c)(9).

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

V. Have the requirements for approval of a SIP revision been met?

    The State submission has met the public notice requirements for SIP 
submissions in accordance with 40 CFR 51.102. The submission also 
satisfied the completeness criteria of 40 CFR part 51, appendix V. The 
State provided public notice on this SIP revision from May 15, 2018, to 
August 2, 2018, and received twelve comments from the EPA that related 
to Missouri's lack of an adequate demonstration that the rule could be 
removed from the SIP in accordance with section 110(l) of the CAA, 
whether the rule applied to new sources and other implications related 
to rescinding the rule. Missouri's July 11, 2019 letter and December 3, 
2018 response to comments on the state rescission rulemaking addressed 
the EPA's comments. In addition, the revision meets the substantive SIP 
requirements of the CAA, including section 110 and implementing 
regulations.

VI. What action is the EPA taking?

    The EPA is proposing to approve Missouri's request to rescind 10 
CSR 10-5.410 from the SIP because the rule applied to a single facility 
that ceased the manufacture of polystyrene resin, which caused the 
facility to initially be subject to the rule, in 2009 and because the 
rule is not applicable to any other source. Therefore, the rule no 
longer serves to reduce emissions in the St. Louis Area. Further, any 
new sources or major modifications of existing sources in the St. Louis 
Area are subject to NSR permitting.\9\ We are processing this as a 
proposed action because we are soliciting comments on this proposed 
action. Final rulemaking will occur after consideration of any 
comments.
---------------------------------------------------------------------------

    \9\ ``NSR Permitting'' includes PSD permitting in areas 
designated attainment and unclassifiable, NA NSR in areas designated 
nonattainment and minor source permitting.
---------------------------------------------------------------------------

VII. Incorporation by Reference

    In this document, the EPA is proposing to amend regulatory text 
that includes incorporation by reference. As described in the proposed 
amendments to 40 CFR part 52 set forth below, the EPA is proposing to 
remove provisions of the EPA-Approved Missouri Regulation from the 
Missouri State Implementation Plan, which is incorporated by reference 
in accordance with the requirements of 1 CFR part 51.

VIII. Statutory and Executive Order Reviews

    Under the CAA, the Administrator is required to approve a SIP 
submission that complies with the provisions of the Act and applicable 
Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in 
reviewing SIP submissions, EPA's role is to approve state choices, 
provided that they meet the criteria of the CAA. 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:
     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 13563 (76 FR 3821, January 21, 2011);
     Is not an Executive Order 13771 (82 FR 9339, February 2, 
2017) regulatory action because SIP approvals are exempted under 
Executive Order 12866.
     Does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
     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.);
     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);
     Does not have federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999);
     Is not an economically significant regulatory action based 
on health or safety risks subject to Executive Order 13045 (62 FR 
19885, April 23, 1997);
     Is not a significant regulatory action subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001);
     Is not subject to requirements of the National Technology 
Transfer and Advancement Act (NTTA) because this rulemaking does not 
involve technical standards; and
     Does not provide EPA with the discretionary authority to 
address, as appropriate, disproportionate human health or environmental 
effects, using practicable and legally permissible methods, under 
Executive Order 12898 (59 FR 7629, February 16, 1994).
    The SIP is not approved to apply on any Indian reservation land or 
in any other area where 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 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).
