40 CFR Part 52

[EPA-R05-OAR-2020-0369; FRL-10024-65-Region 5]

Air Plan Approval; Indiana; Two Revised Sulfur Dioxide Rules for 
Lake County

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is approving 
revisions to the Indiana sulfur dioxide (SO2) State 
Implementation Plan (SIP). The State of Indiana has requested these SIP 
revisions to satisfy the requirements of a Federal consent decree. 
These revisions limit annual bypass venting limits in the sulfur-
containing waste gas emissions from a coking and power generating 
facility in Lake County, Indiana, which is owned and operated by 
Indiana Harbor Coke Company (IHCC) and Cokenergy LLC (Cokenergy). The 
revisions also require Cokenergy to operate and maintain a permanent 
SO2 flow rate monitor and improve the percent control 
capture efficiency of the facility. In addition, the rulemaking 
includes technical corrections and clarifications that do not have a 
substantive effect of the application of the rules.

DATES: This final rule is effective on July 7, 2021.

ADDRESSES: EPA has established a docket for this action under Docket ID 
No. EPA-R05-OAR-2020-0369. All documents in the docket are listed on 
the www.regulations.gov website. Although listed in the index, some

I. Background Information

    On February 11, 2021, EPA proposed to approve revisions to 326 
Indiana Administrative Code (IAC) 7-4.1-7 (Cokenergy) and 326 IAC 7-
4.1-8 (IHCC) to limit annual bypass venting of sulfur containing waste 
gases from a coking and power generating facility owned and operated by 
Indiana Harbor Coke Company and Cokenergy LLC in Lake County, Indiana. 
See 86 FR 9038. The proposed revision for Cokenergy also requires it to 
operate and maintain a permanent SO2 flow rate monitor at 
the facility. The state of Indiana has requested these SIP revisions to 
satisfy the requirements of a Federal consent decree. An explanation of 
the Clean Air Act requirements, a detailed analysis of the revisions, 
and EPA's reasons for proposing approval were provided in the notice of 
proposed rulemaking (NPRM) and will not be restated here.

II. Public Comments

    EPA provided a 30-day review and comment period for the February 
11, 2021, proposed rule. The comment period ended on March 15, 2021. 
EPA received a total of three comments, all from private citizens, on 
the proposed approval of this rule. Two comments were in support of the 
action and one comment was adverse. No further discussion of the 
supporting comments is necessary. EPA summarizes and responds to the 
adverse comment below.
    Comment: This rule should be more restricting on the harmful gases 
that are released into the atmosphere. The 19% of coke waste that is 
pumped into our atmosphere 24 hours a day should be cut by at least 2% 
for the year 2021. The option for retubing defeats the new revision 
because it allows the company to continue to let a maximum of 14% 
rather than the proposed 13%.
    Response: The provision relating to 19% of the coke oven waste 
gases leaving the common tunnel was not reopened by our proposal and is 
not being revised by this rulemaking. As per the consent decree, 
Indiana was not required to amend the facility's maximum percentage of 
coke oven gases leaving the common tunnel that can be vented into the 
atmosphere. Indiana has retained the original limit which was adopted 
to be protective of the previous SO2 standard. See 70 FR 
56129. No one timely challenged that previous determination and it is 
too late to raise an objection now. As such, this portion of the 
comment is outside of the scope of this action.
    In addition, the commentor raised a concern over the increase in 
bypass venting allowed during a ``retubing year.'' This term is defined 
in the proposed revision as a year in which there is a replacement of: 
(1) Waterwalls, evaporator tubes, economizer tubes, or superheater 
module pendants within the heat recovery steam generator; and (2) 
exterior casing, insulation, and refractory, as needed. To comply with 
the consent decree, IHCC and Cokenergy submitted to Indiana a request 
to lower the facility's maximum bypass venting to 13%, down from 
previously allowed 14%, except during a heat recovery steam generator 
(HRSG) retubing year. During a retubing year, the facility is allowed 
increase the bypass venting back up to the previously permissible 
maximum of 14% when at least 3.25% of the bypass venting is due to the 
HRSG retubing. In any year, one or more HRSGs may be brought offline to 
replace parts that are prone to wear due to operating at extreme 
temperatures. The need to increase bypass venting arises from the fact 
that the facility is unable to construct redundant HRSGs that could 
accept the waste gas stream when the primary HRSG is offline. As such, 
when a HRSG is offline due to retubing, the facility will need to 
divert a higher percentage of the gas stream to the atmosphere through 
bypass venting. This provision allows the facility to preserve its 
pollution control devices located downstream that cannot handle the 
high temperature of the gas stream that does not first go through a 
HRSG. EPA agrees with this technical justification for the need to 
allow increase bypass venting during a retubing year to the previously 
permissible 14%. Overall, this revision will lower the percentage of 
coke oven gases that are vented to the atmosphere via bypass venting.

III. Final Action

    EPA is approving Indiana's July 10, 2020 request to revise 326 IAC 
7-4.1-7 and 326 IAC 7-4.1-8. These SO2 SIP revisions 
strengthen the SIP and fulfill the requirements of the Federal consent 
decree with Cokenergy LLC and IHCC.

IV. Incorporation by Reference

    In this rule, EPA is finalizing regulatory text that includes 
incorporation by reference. In accordance with requirements of 1 CFR 
51.5, EPA is finalizing the incorporation by reference of the Indiana 
Regulations described in the amendments to 40 CFR part 52 set forth 
below. EPA has made, and will continue to make, these documents 
generally available through www.regulations.gov, and at the EPA Region 
5 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 EPA for inclusion in 
the SIP, have been incorporated by reference by EPA into that plan, are 
fully federally enforceable under sections 110 and 113 of the CAA as of 
the effective date of the final rulemaking of EPA's approval, and will 
be incorporated by reference in the next update to the SIP 
compilation.\1\

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, 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:
     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);

[[Page 30203]]

     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 Clean Air Act; 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).
    In addition, 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).
    The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the 
Small Business Regulatory Enforcement Fairness Act of 1996, generally 
provides that before a rule may take effect, the agency promulgating 
the rule must submit a rule report, which includes a copy of the rule, 
to each House of the Congress and to the Comptroller General of the 
United States. EPA will submit a report containing this action and 
other required information to the U.S. Senate, the U.S. House of 
Representatives, and the Comptroller General of the United States prior 
to publication of the rule in the Federal Register. A major rule cannot 
take effect until 60 days after it is published in the Federal 
Register. 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 August 6, 2021. 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).)
