Download as PDF 13716 Federal Register / Vol. 83, No. 62 / Friday, March 30, 2018 / Proposed Rules states to have SIP provisions that comply with the requirements of CAA section 128. Because EPA is proposing to approve provisions into Mississippi’s SIP to meet the significant portion of income requirements of section 128(a)(1) as discussed above, it is also proposing to fully approve the SIP submission with respect to the related requirements of section 110(a)(2)(E)(ii) for the NAAQS previously mentioned. EPA notes that section 128 is not NAAQS-specific, and thus once a state has met the requirements of section 128 it will continue to do so for purposes of future NAAQS, unless there were future changes to the approved SIP provisions which would require further evaluation. amozie on DSK30RV082PROD with PROPOSALS V. Incorporation by Reference In this notice, EPA is proposing to include in a final EPA rule regulatory text that includes incorporation by reference. In accordance with the requirements of 1 CFR 51.5, EPA is proposing to incorporate by reference Mississippi Code section 49–2–5 to include certain section 128 requirements for the MDEQ Commission on Environmental Quality; and Appendix C–26, ‘‘Air Emissions Regulations for the Prevention, Abatement, and Control of Air Contaminants’’ Title 11, Part 2, Chapter 1, Rule 1.1, and Appendix A–13, ‘‘Regulations Regarding Administrative Procedures Pursuant to the Mississippi Administrative Procedures Act’’, Title 11, Part 1 Chapter 5, Rule 5.1 to incorporate certain section 128 requirements for the MDEQ Permit Board. EPA has made, and will continue to make, these materials generally available through www.regulations.gov and at the EPA Region 4 office (please contact the person identified in the FOR FURTHER INFORMATION CONTACT section of this preamble for more information). VI. Proposed Action As described above, EPA is proposing to approve that the Mississippi SIP meets the significant portion of income requirements of 128(a)(1) of the CAA. EPA is also proposing to conclude that, if Mississippi’s June 23, 2017, and February 2, 2018, SIP revisions are approved, the section 110(a)(2)(E)(ii) requirements are met for the 2008 8hour Ozone, 2008 Lead, 2010 NO2, 2010 SO2, and 1997, 2006 and 2012 PM2.5, NAAQS for section 110(a)(2)(E)(ii). Consequently, if EPA finalizes approval of this action, the deficiencies identified in the previous partial disapprovals of Mississippi infrastructure SIP submissions related to the state board requirements for the 2008 8-hour Ozone, 2008 Lead, 2010 NO2, 2010 SO2, and VerDate Sep<11>2014 18:11 Mar 29, 2018 Jkt 244001 1997, 2006 and 2012 PM2.5 NAAQS will be cured. Finally, EPA is proposing to approve the new supplemental provisions regarding representation of the public interest of section 128(a)(1) for the MDEQ Permit Board and Mississippi Commission on Environmental Quality, and disclosure of potential conflicts of interest of section 128(a)(2) for the Mississippi Commission on Environmental Quality. VII. 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. See 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. This action merely proposes to approve state law as meeting Federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, this proposed 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 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 CAA; and PO 00000 Frm 00026 Fmt 4702 Sfmt 4702 • 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 as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), nor will it impose substantial direct costs on tribal governments or preempt tribal law.

These requirements will sunset after: (1) The revisions to Rule R18–2–715.02 are approved into the SIP, and (2) Rule B1302 (for the Hayden Smelter) and Rule R18–2–C1302 (for the Miami Smelter) take effect. The EPA’s technical support documents (TSDs) have more information about these rules. On November 12, 2008, the EPA published a final rule revising the lead National Ambient Air Quality Standards (NAAQS). On June 22, 2010, the EPA promulgated a new 1-hour primary sulfur dioxide (SO2) NAAQS. CAA section 172(c)(1) requires SIPs for nonattainment areas to provide for implementation of all reasonably available control measures (RACM), including reasonably available control technology (RACT), and provide for attainment of the NAAQS. The EPA designated the Hayden area as nonattainment for lead in 2014 (79 FR 52205) and designated the Hayden and Miami areas as nonattainment for SO2 in 2013 (78 FR 47191). Rule R18–2–B1301 establishes control requirements for lead emissions from the copper smelter located in the Hayden, AZ nonattainment area (‘‘Hayden Smelter’’). Rule R18–2–C1302 establishes control requirements for SO2 emissions from the copper smelter located in the Miami, AZ nonattainment area (‘‘Miami Smelter’’). Appendix 14 requires the evaluation and characterization of fugitive lead and SO2 emissions from the Hayden Smelter. Rule R18–2–715.02 contains 1 In addition to the rules addressed in this proposal, ADEQ’s April 6, 2017 submittal also included R18–2–B1301.01—Limits on Lead-Bearing Fugitive Dust from the Hayden Smelter; R18–2– B1302—Limits on SO2 Emissions from the Hayden Smelter; R18–2–715—Standards of Performance for Existing Primary Copper Smelters: Site-Specific Requirements; and R18–2–715.01—Standards of Performance for Existing Primary Copper Smelters; Compliance and Monitoring. The EPA has already approved R18–2–B1301.01 into the SIP, 83 FR 7614 (February 22, 2018) and intends to take action on the remaining rules in a separate rulemaking. On July 17, 2017, the EPA determined that the submittal for the rules and documents in Table 1 met the completeness criteria in 40 CFR part 51 Appendix V, which must be met before formal EPA review. B. Are there other versions of these rules? There are no previous versions of Rules R18–2–B1301, R18–2–C1302 or Appendix 14 in the SIP. We approved an earlier version of Rule R18–2–715.02 into the SIP on November 1, 2004 (69 FR 63321). C.

The EPA’s Evaluation and Action A. How is the EPA evaluating the rules? SIP rules must be enforceable (see CAA section 110(a)(2)), must not interfere with applicable requirements concerning attainment and reasonable further progress or other CAA requirements (see CAA section 110(l)), and must not modify certain SIP control requirements in nonattainment areas without ensuring equivalent or greater emissions reductions (see CAA section 193). The EPA will address the overall E:\FR\FM\30MRP1.SGM 30MRP1 13718 Federal Register / Vol. 83, No. 62 / Friday, March 30, 2018 / Proposed Rules RACM/RACT requirement for the Hayden lead nonattainment area in the context of our action on ADEQ’s lead plan (‘‘SIP Revision: Hayden Lead Nonattainment Area,’’ submitted by ADEQ to the EPA on March 3, 2017), and we will address the RACM/RACT requirement for the Miami SO2 nonattainment area in the context of our action on ADEQ’s SO2 plan (‘‘Arizona SIP Revision: Miami Sulfur Dioxide Nonattainment Area for the 2010 SO2 NAAQS,’’ submitted by ADEQ to the EPA on March 8, 2017). Therefore, our stringency evaluations here consider whether Rules R18–2–B1301 and R18– 2–C1302 implement reasonable controls for the two subject criteria pollutants at the Hayden and Miami smelters.2 Guidance and policy documents that we use to evaluate enforceability, rule stringency, and SIP revision requirements for the applicable criteria pollutants include the following: 1. ‘‘Issues Relating to VOC Regulation Cutpoints, Deficiencies, and Deviations,’’ EPA, May 25, 1988 (the Bluebook, revised January 11, 1990). 2. ‘‘Guidance Document for Correcting Common VOC & Other Rule Deficiencies,’’ EPA Region 9 (the Little Bluebook, August 21, 2001). 3. ‘‘Implementation of the 2008 Lead National Ambient Air Quality Standards: Guide to Developing Reasonably Available Control Measures (RACM) for Controlling Lead Emissions,’’ EPA Office of Air Quality Planning and Standards (March 2012). 4. ‘‘Guidance for 1-Hour SO2 Nonattainment Area SIP Submissions,’’ EPA Office of Air Quality Planning and Standards (April 23, 2014). 5.

National Emission Standard for Hazardous Air Pollutants for Secondary Lead Smelting (40 CFR part 63, subpart X). amozie on DSK30RV082PROD with PROPOSALS 2 Appendix 14 does not establish control requirements, so it is not subject to a stringency evaluation. Appendix 14 is still subject to enforceability and SIP consistency evaluations, which we describe in our TSD. The revisions to sunset the existing requirements of Rule R18–2– 715.02, are evaluated in context with Appendix 14. See the TSD evaluating Appendix 14 for more information on Rule R18–2–715.02. Rule R18–2– B1302 regulates SO2 emissions at the Hayden Smelter, and will be evaluated in a separate rulemaking. The revisions to sunset the existing requirements of Rules R18–2–715 and R18–2– 715.01 in relation to the Hayden Smelter will be evaluated in context with R18–2–B1302. VerDate Sep<11>2014 18:11 Mar 29, 2018 Jkt 244001 B. Do the rules meet the evaluation criteria? These rules are consistent with CAA requirements and relevant guidance regarding enforceability, rule stringency, and SIP revisions. The TSDs have more information on our evaluation. C. EPA Recommendations To Further Improve the Rules The TSDs describe additional rule revisions that we recommend for the next time the State modifies the rules. D. Public Comment and Proposed Action As authorized in section 110(k)(3) of the Act, the EPA proposes to fully approve the submitted rules because they fulfill all relevant requirements. We will accept comments from the public on this proposal until April 30, 2018. If we take final action to approve the submitted rules, our final action will incorporate these rules into the federally enforceable SIP. III. Incorporation by Reference In this rule the EPA is proposing to include in a final EPA rule regulatory text that includes incorporation by reference. In accordance with requirements of 1 CFR 51.5, the EPA is proposing to incorporate by reference the ADEQ rules described in Table 1 of this preamble. The EPA has made, and will continue to make, these materials available through www.regulations.gov and at the EPA Region IX Office (please contact the person identified in the FOR FURTHER INFORMATION CONTACT section of this preamble for more information). IV. 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, the EPA’s role is to approve state choices, provided that they meet the criteria of the Act. Accordingly, this proposed action merely proposes to approve state law as meeting federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, this proposed 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 PO 00000 Frm 00028 Fmt 4702 Sfmt 4702 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.

                                           Copper Smelters; Fugitive
                                           Emissions.
----------------------------------------------------------------------------------------------------------------

    On July 17, 2017, the EPA determined that the submittal for the 
rules and documents in Table 1 met the completeness criteria in 40 CFR 
part 51 Appendix V, which must be met before formal EPA review.

B. Are there other versions of these rules?

    There are no previous versions of Rules R18-2-B1301, R18-2-C1302 or 
Appendix 14 in the SIP. We approved an earlier version of Rule R18-2-
715.02 into the SIP on November 1, 2004 (69 FR 63321).

C. What is the purpose of the submitted rules and rule revisions?

    On November 12, 2008, the EPA published a final rule revising the 
lead National Ambient Air Quality Standards (NAAQS). On June 22, 2010, 
the EPA promulgated a new 1-hour primary sulfur dioxide 
(SO2) NAAQS. CAA section 172(c)(1) requires SIPs for 
nonattainment areas to provide for implementation of all reasonably 
available control measures (RACM), including reasonably available 
control technology (RACT), and provide for attainment of the NAAQS. The 
EPA designated the Hayden area as nonattainment for lead in 2014 (79 FR 
52205) and designated the Hayden and Miami areas as nonattainment for 
SO2 in 2013 (78 FR 47191). Rule R18-2-B1301 establishes 
control requirements for lead emissions from the copper smelter located 
in the Hayden, AZ nonattainment area (``Hayden Smelter''). Rule R18-2-
C1302 establishes control requirements for SO2 emissions 
from the copper smelter located in the Miami, AZ nonattainment area 
(``Miami Smelter''). Appendix 14 requires the evaluation and 
characterization of fugitive lead and SO2 emissions from the 
Hayden Smelter. Rule R18-2-715.02 contains the existing requirements 
for fugitive SO2 emissions studies at both smelters. These 
requirements will sunset after: (1) The revisions to Rule R18-2-715.02 
are approved into the SIP, and (2) Rule B1302 (for the Hayden Smelter) 
and Rule R18-2-C1302 (for the Miami Smelter) take effect. The EPA's 
technical support documents (TSDs) have more information about these 
rules.

II. The EPA's Evaluation and Action

A. How is the EPA evaluating the rules?

    SIP rules must be enforceable (see CAA section 110(a)(2)), must not 
interfere with applicable requirements concerning attainment and 
reasonable further progress or other CAA requirements (see CAA section 
110(l)), and must not modify certain SIP control requirements in 
nonattainment areas without ensuring equivalent or greater emissions 
reductions (see CAA section 193). The EPA will address the overall

[[Page 13718]]

RACM/RACT requirement for the Hayden lead nonattainment area in the 
context of our action on ADEQ's lead plan (``SIP Revision: Hayden Lead 
Nonattainment Area,'' submitted by ADEQ to the EPA on March 3, 2017), 
and we will address the RACM/RACT requirement for the Miami 
SO2 nonattainment area in the context of our action on 
ADEQ's SO2 plan (``Arizona SIP Revision: Miami Sulfur 
Dioxide Nonattainment Area for the 2010 SO2 NAAQS,'' 
submitted by ADEQ to the EPA on March 8, 2017). Therefore, our 
stringency evaluations here consider whether Rules R18-2-B1301 and R18-
2-C1302 implement reasonable controls for the two subject criteria 
pollutants at the Hayden and Miami smelters.\2\
---------------------------------------------------------------------------

    \2\ Appendix 14 does not establish control requirements, so it 
is not subject to a stringency evaluation. Appendix 14 is still 
subject to enforceability and SIP consistency evaluations, which we 
describe in our TSD. The revisions to sunset the existing 
requirements of Rule R18-2-715.02, are evaluated in context with 
Appendix 14. See the TSD evaluating Appendix 14 for more information 
on Rule R18-2-715.02. Rule R18-2-B1302 regulates SO2 
emissions at the Hayden Smelter, and will be evaluated in a separate 
rulemaking. The revisions to sunset the existing requirements of 
Rules R18-2-715 and R18-2-715.01 in relation to the Hayden Smelter 
will be evaluated in context with R18-2-B1302.
---------------------------------------------------------------------------

    Guidance and policy documents that we use to evaluate 
enforceability, rule stringency, and SIP revision requirements for the 
applicable criteria pollutants include the following:
    1. ``Issues Relating to VOC Regulation Cutpoints, Deficiencies, and 
Deviations,'' EPA, May 25, 1988 (the Bluebook, revised January 11, 
1990).
    2. ``Guidance Document for Correcting Common VOC & Other Rule 
Deficiencies,'' EPA Region 9 (the Little Bluebook, August 21, 2001).
    3. ``Implementation of the 2008 Lead National Ambient Air Quality 
Standards: Guide to Developing Reasonably Available Control Measures 
(RACM) for Controlling Lead Emissions,'' EPA Office of Air Quality 
Planning and Standards (March 2012).
    4. ``Guidance for 1-Hour SO2 Nonattainment Area SIP 
Submissions,'' EPA Office of Air Quality Planning and Standards (April 
23, 2014).
    5. National Emission Standard for Hazardous Air Pollutants for 
Primary Copper Smelting (40 CFR part 63, subpart QQQ).
    6. National Emission Standard for Hazardous Air Pollutants for 
Secondary Lead Smelting (40 CFR part 63, subpart X).

B. Do the rules meet the evaluation criteria?

    These rules are consistent with CAA requirements and relevant 
guidance regarding enforceability, rule stringency, and SIP revisions. 
The TSDs have more information on our evaluation.

C. EPA Recommendations To Further Improve the Rules

    The TSDs describe additional rule revisions that we recommend for 
the next time the State modifies the rules.

D. Public Comment and Proposed Action

    As authorized in section 110(k)(3) of the Act, the EPA proposes to 
fully approve the submitted rules because they fulfill all relevant 
requirements. We will accept comments from the public on this proposal 
until April 30, 2018. If we take final action to approve the submitted 
rules, our final action will incorporate these rules into the federally 
enforceable SIP.

III. Incorporation by Reference

    In this rule the EPA is proposing to include in a final EPA rule 
regulatory text that includes incorporation by reference. In accordance 
with requirements of 1 CFR 51.5, the EPA is proposing to incorporate by 
reference the ADEQ rules described in Table 1 of this preamble. The EPA 
has made, and will continue to make, these materials available through 
www.regulations.gov and at the EPA Region IX Office (please contact the 
person identified in the FOR FURTHER INFORMATION CONTACT section of 
this preamble for more information).

IV. 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, the EPA's role is to approve state choices, 
provided that they meet the criteria of the Act. Accordingly, this 
proposed action merely proposes to approve state law as meeting federal 
requirements and does not impose additional requirements beyond those 
imposed by state law. For that reason, this proposed 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 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 CAA; and
     Does not provide the EPA with the discretionary authority 
to address disproportionate human health or environmental effects with 
practical, appropriate, and legally permissible methods under Executive 
Order 12898 (59 FR 7629, February 16, 1994).
    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 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).
