Approval and Promulgation of Air Quality Implementation Plans; Arizona; Regional Haze Federal Implementation Plan; Reconsideration
AGENCY: Environmental Protection Agency (EPA).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) is taking final action to revise certain provisions in the Arizona Regional Haze (RH) Federal Implementation Plan (FIP) that apply to the Nelson Lime Plant. In response to a request for reconsideration from the plant's owner, Lhoist North America of Arizona, Inc. (LNA), we are replacing the control technology demonstration requirements for emissions of nitrogen oxides (NOX) applicable to Kilns 1 and 2 at the Nelson Lime Plant with revised recordkeeping and reporting requirements. We are not revising any of the emission limits that apply to these units, including the existing NOX emission limits, which can be met with selective non-catalytic reduction (SNCR) control technology. We also are taking final action to correct a misprint of the regulatory requirements in a table in the Arizona RH FIP that identifies the emission limits for NOX and sulfur dioxide (SO2) at each kiln.
DATES: Effective date: This rule is effective May 18, 2015.
ADDRESSES: EPA has established docket number EPA-R09-OAR-2014-0861 for this action.

I. Summary of Proposed Action
EPA proposed on January 13, 2015, to revise certain Best Available Retrofit Technology (BART) requirements in the FIP related to reducing NOX emissions from Kilns 1 and 2 at the Nelson Lime Plant.\2\ As described in the proposal, the revision consists of several components, including the removal of the control technology demonstration requirements, the addition of revised recordkeeping and reporting requirements, and the correction of an error in a table.\3\ We proposed to find that these changes are reasonable and appropriate based on information from LNA regarding the effectiveness of using SNCR to control NOX emissions at another lime plant. The proposed rule addressing the Nelson Lime Plant did not change the emission limits, compliance deadlines, or the compliance determination methods established in the final rule for the Arizona RH FIP.

II. Background on Petition for Reconsideration and Stay
LNA submitted a petition to EPA on October 31, 2014, seeking administrative reconsideration and a partial stay of the final rule under CAA section 307(d)(7)(B).\4\ Specifically, LNA requested that EPA eliminate the control technology demonstration requirements (also known as ``optimization requirements'') for the Nelson Lime Plant. In support of its petition, LNA provided additional data regarding the performance of SNCR control technology at lime kilns located at another LNA facility, the O'Neal Lime Plant in Calera, Alabama. In the petition, LNA also requested a stay of the provisions in the FIP applicable to the Nelson Lime Plant if EPA did not propose action on its petition prior to December 31, 2014.\5\ EPA sent a letter to LNA on November 20, 2014, granting reconsideration of the optimization requirements pursuant to CAA section 307(d)(7)(B).\6\
---------------------------------------------------------------------------
\4\ Letter from Eric Hiser, Jorden Bischoff & Hiser, to Regina McCarthy, EPA (October 31, 2014).
\5\ Because the proposal was signed prior to December 31, 2014, we consider LNA's request for a stay to be moot.
\6\ Letter from Jared Blumenfeld, EPA, to Eric Hiser, Jorden Bischoff & Hiser (November 20, 2014).
---------------------------------------------------------------------------
III. Public Comments
In the proposed rule, EPA provided 45 days for the public to submit comments on the proposed revision to the Arizona RH FIP. During the public comment period, we received one set of comments from the Mississippi Lime Company (``Mississippi Lime'').\7\ The comments from Mississippi Lime focused on the requirement for LNA to install SNCR controls at the Nelson Lime Plant. The comments and our responses are summarized below.
---------------------------------------------------------------------------
\7\ Letter from Kimberly S. L. Bauman, Mississippi Lime Company, to Thomas Webb, EPA (February 27, 2015).
---------------------------------------------------------------------------
Comment: Mississippi Lime stated that SNCR technology has not been identified as Best Available Control Technology (BACT) for lime kilns in EPA's control technology clearinghouse or as an applied emission control in publicly available documents for LNA's O'Neal facility. The commenter further noted that there is no discussion of SNCR at the O'Neal facility in publicly available documents such as operating permits, quarterly excess emission reports, or emission inventory reports issued by or submitted to the Alabama Department of Environmental Management.
Response: EPA does not dispute Mississippi Lime's assertion that publicly available information on SNCR technology for lime kilns may be limited. However, any such lack of information is irrelevant to this action. In particular, in a final rule published on September 3, 2014, EPA determined that SNCR is technically feasible and constitutes BART for Kilns 1 and 2 at Nelson Lime Plant.\8\ We have not proposed to reconsider or otherwise revise those determinations.
---------------------------------------------------------------------------
\8\ See 79 FR 9318, 9337-9339 for proposed BART analysis and determination (February 18, 2014); 79 FR 52420, 52424 for final BART determination (September 3, 2014).
---------------------------------------------------------------------------
Comment: Mississippi Lime contended that LNA, according to public documents provided to Illinois EPA, has stated that its O'Neal facility in Calera, Alabama, is controlling lime kiln emissions to meet emission limits under a permit that relies on a proprietary SNCR technology that was patented by its predecessor, Chemical Lime Company.
Response: EPA does not dispute that the SNCR technology in use at the O'Neal facility may be proprietary. EPA relied on an analysis of the effectiveness of the SNCR technology to control emissions at the O'Neal facility to confirm that the emission limit we established for the Nelson Lime Plant is reasonable and appropriate. Based on the results of our analysis described in our proposal, we proposed and are now taking final action to replace a series of prescriptive control technology demonstration requirements with new recordkeeping and reporting requirements for LNA. The fact that the SNCR technology in use at the O'Neal
Page 21178
facility may be proprietary has no bearing on the purpose or substance of our analysis.
Comment: Mississippi Lime asserted that SNCR technology on lime kilns is an unproven control strategy. Thus, the commenter had significant concerns that this technology and the corresponding FIP will be used inappropriately for the establishment of future BACT or BART determinations.
Response: As noted above, EPA has already determined that SNCR is a feasible control technology for Kilns 1 and 2 at the Nelson Lime Plant and has set emission limits that correspond to the use of SNCR in our final rule on the Arizona RH FIP.\9\ Because our proposal and this final action address only the optimization requirements, and are not related to previous determinations in the FIP, this comment on our proposal is not relevant.
---------------------------------------------------------------------------
\9\ Id.
---------------------------------------------------------------------------
Comment: Mississippi Lime is concerned that if LNA's proposed SNCR system for the Nelson Lime Plant uses LNA's proprietary and patented technology, competitors like Mississippi Lime may also be required to use the patented technology in the future. The commenter alleged that LNA could interfere with a competitor's obligation to use SNCR by refusing to license its technology or by requiring exorbitant licensing fees. This would enable LNA to use its patent to gain a competitive advantage over the entire lime industry in the United States.
Response: While not the subject of this final rule, the Arizona RH FIP only requires LNA to meet a specified emission limit. LNA may use whatever technology it wants to achieve the required limit, including proprietary technology. If LNA were to refuse to license its proprietary technology or to charge exorbitant fees at some point in the future, then Mississippi Lime could argue in any future regulatory actions that the technology is not available or is not cost-effective.
IV. Final Action
We are taking final action to revise parts of the Arizona RH FIP that apply to the Nelson Lime Plant. In particular, we are removing the control technology demonstration requirements included in the FIP for Nelson Lime Plant and replacing those with less prescriptive recordkeeping and reporting requirements. For the revised recordkeeping and reporting requirements, LNA must submit a summary of the SNCR design and of the SNCR process improvement activities. In addition, we are correcting a misprint in the Federal Register in a table that lists NOX and SO2 emission limits for the kilns at the Nelson Lime Plant. The table appears with the correct labels in the regulatory text that follows this final rule. This rule constitutes EPA's final action on LNA's petition for reconsideration of the Arizona RH FIP.
EPA also is making a final determination that the revisions in this final rule do not interfere with any applicable requirements of the CAA. CAA section 110(l) requires that any revision to an implementation plan shall not be approved by the Administrator if the revision would interfere with any applicable requirement concerning attainment and reasonable further progress or any other applicable requirement of the CAA. These final revisions do not alter the amount or timing of the emission reductions from the Nelson Lime Plant.
V. Statutory and Executive Order Reviews
-
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. This rule applies to only one facility and is therefore not a rule of general applicability.
-
Paperwork Reduction Act (PRA)
This action does not impose an information collection burden under the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. This rule applies to only one facility. Therefore, its recordkeeping and reporting provisions do not constitute a ``collection of information'' as defined under 44 U.S.C. 3502(3) and 5 CFR 1320.3(c).
-
Regulatory Flexibility Act (RFA)
I certify that this proposed action will not have a significant economic impact on a substantial number of small entities. This action will not impose any requirements on small entities. Pursuant to 13 CFR 121.201, footnote 1, a firm is small if it is in NAICS 327410 (lime manufacturing) and the concern and its affiliates have no more than 500 employees. LNA is affiliated with the LNA Group, which has more than 5,500 employees.\10\ Therefore, LNA is not a small business.
-
Unfunded Mandates Reform Act (UMRA)
This action does not contain an unfunded mandate of $100 million or more as described in UMRA, 2 U.S.C. 1531-1538, and does not significantly or uniquely affect small governments.
-
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.
-
Executive Order 13175: Consultation and Coordination With Indian Tribal Governments
This action does not have tribal implications, as specified in Executive Order 13175. It will not have substantial direct effects on any Indian tribes, on the relationship between the Federal Government and Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes. Thus, Executive Order 13175 does not apply to this action.
-
Executive Order 13045: Protection of Children From Environmental Health Risks and Safety Risks
EPA interprets EO 13045 as applying only to those regulatory actions that concern health or safety risks that 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 concern an environmental health risk or safety risk.
-
Executive Order 13211: Actions Concerning Regulations 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
This rulemaking does not involve technical standards. EPA is not revising any technical standards or imposing any new technical standards in this action.
-
Executive Order 12898: Federal Actions To Address Environmental Justice in Minority Populations and Low-Income Populations
EPA believes the human health or environmental risk addressed by this action will not have potential disproportionately high and adverse human health or environmental effects
Page 21179
on minority, low-income or indigenous populations. These final revisions do not alter the amount or timing of the emission reductions from the Nelson Lime Plant.
-
Congressional Review Act (CRA)
This rule is exempt from the CRA because it is a rule of particular applicability.
L. Petitions for Judicial Review
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 June 16, 2015. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this rule 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 CAA section 307(b)(2). In addition, pursuant to CAA section 307(d)(1)(B), this action is subject to the requirements of CAA section 307(d).

(iii) The owner/operator shall submit notification of initial startup of any such equipment.
(10) Equipment operations. (i) At all times, including periods of startup, shutdown, and malfunction, the owner/operator shall, to the extent practicable, maintain and operate the kilns, including associated air pollution control equipment, in a manner consistent with good air pollution control practices for minimizing emissions. Pollution control equipment shall be designed and capable of operating properly to minimize emissions during all expected operating conditions. Determination of whether acceptable operating and maintenance procedures are being used will be based on information available to the Regional Administrator, which may include, but is not limited to, monitoring results, review of operating and maintenance procedures, and inspection of the kilns.
(ii) After completion of installation of ammonia injection on a kiln, the owner/operator shall inject sufficient ammonia to achieve compliance with the NOX emission limits from paragraph (i)(3) of this section for that kiln while preventing excessive ammonia emissions.
(11) Enforcement. Notwithstanding any other provision in this implementation plan, any credible evidence or information relevant as to whether the kiln would have been in compliance with applicable requirements if the appropriate performance or compliance test had been performed can be used to establish whether or not the owner/operator has violated or is in violation of any standard or applicable emission limit in the plan.
