E7-8560. Approval and Promulgation of Implementation Plans; State of Missouri

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Direct final rule.

SUMMARY:

EPA is approving an amendment to the Missouri State Implementation Plan (SIP). This action approves an amendment to the SIP-approved Doe Run Herculaneum Consent Judgment to remove language specifying the exact bag technology to be used in the baghouses. Related performance standard requirements will remain unchanged. This action is independent and does not affect the revision to the Missouri SIP due in April 2007, in response to the SIP Call issued April 14, 2006, to bring the area of Herculaneum into compliance with the lead National Ambient Air Quality Standard.

DATES:

This direct final rule will be effective July 3, 2007, without further notice, unless EPA receives adverse comment by June 4, 2007. If adverse comment is received, EPA will publish a timely withdrawal of the direct final rule in the Federal Register informing the public that the rule will not take effect.

SUPPLEMENTARY INFORMATION:

Throughout this document whenever “we,” “us,” or “our” is used, we mean EPA. This section provides additional information by addressing the following questions:

What is a SIP?

What is the Federal approval process for a SIP?

What does Federal approval of a state regulation mean to me?

What is being addressed in this document?

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

What action is EPA taking?

What is a SIP?

Section 110 of the Clean Air Act (CAA) requires states to develop air pollution regulations and control strategies to ensure that State air quality meets the national ambient air quality standards established by EPA. These ambient standards are established under section 109 of the CAA, and they currently address six criteria pollutants. These pollutants are: carbon monoxide, nitrogen dioxide, ozone, lead, particulate matter, and sulfur dioxide.

Each State must submit these regulations and control strategies to us for approval and incorporation into the Federally-enforceable SIP. Each Federally-approved SIP protects air quality primarily by addressing air pollution at its point of origin. These SIPs can be extensive, containing state regulations or other enforceable documents and supporting information such as emission inventories, monitoring networks, and modeling demonstrations.

What is the Federal approval process for a SIP?

In order for State regulations to be incorporated into the Federally-enforceable SIP, States must formally adopt the regulations and control strategies consistent with state and Federal requirements. This process generally includes a public notice, public hearing, public comment period, and a formal adoption by a State-authorized rulemaking body.

Once a State rule, regulation, or control strategy is adopted, the State submits it to us for inclusion into the SIP. We must provide public notice and seek additional public comment regarding the proposed Federal action on the State submission. If adverse comments are received, they must be addressed prior to any final Federal action by us.

All State regulations and supporting information approved by EPA under section 110 of the CAA are incorporated into the Federally-approved SIP. Records of such SIP actions are maintained in the Code of Federal Regulations (CFR) at title 40, part 52, entitled “Approval and Promulgation of Implementation Plans.” The actual State regulations which are approved are not reproduced in their entirety in the CFR outright but are “incorporated by reference,” which means that we have approved a given State regulation with a specific effective date.

What does Federal approval of a state regulation mean to me?

Enforcement of the State regulation before and after it is incorporated into the Federally-approved SIP is primarily a State responsibility. However, after the regulation is Federally approved, we are authorized to take enforcement action against violators. Citizens are also offered legal recourse to address violations as described in section 304 of the CAA.

What is being addressed in this document?

EPA established the National Ambient Air Quality Standard (NAAQS) for lead on October 5, 1978 (43 FR 46246). The standard for lead is set at a level of 1.5 micrograms (μg) of lead per cubic meter (m³) of air, averaged over a calendar quarter. During the 1980s and 1990s, Missouri submitted and EPA approved a number of SIP revisions for lead to address ambient lead problems in various areas of the State. One such area was in Herculaneum, Missouri, which is the site of the Doe Run primary lead smelter. Doe Run-Herculaneum is the only currently operating primary lead smelter in the United States.

The most recent SIP revisions for the Doe Run-Herculaneum area were published in the Federal Register on April 16, 2002 (67 FR 18497). The State submittal included a Consent Judgment entered into by the State and the Doe Run Company, which contained the control and contingency measures with enforceable dates for implementation. As part of the Consent Judgment, a Total Suspended Particulate (TSP) limit of 0.022 grains per dry standard cubic foot was established for Number 7, 8, and 9 Baghouse. The Consent Judgment further specified that Teflon membrane filter bags be used in these baghouses.

Since implementing these specifications, Doe Run found that the Teflon filters resulted in operational issues such as bag cleaning and high operating pressure differentials which reduced bag life and led to higher maintenance. The bags that Doe Run proposes to install are spun-bound pleated filter elements that have approximately twice the filter area as the original bags. The manufacturer's specifications state that this design significantly reduces the differential pressure and air-to-cloth ratios, resulting in improved performance and durability. The pleated bags must meet the current Total Suspended Particulate limits (0.022 grains per dry standard cubic foot) required in the Consent Judgment. MDNR has also modified the Consent Judgment to require a performance test to verify the new filter elements are meeting performance requirements. This action removes language referring to the exact bag technology while leaving the related performance standard requirements in place. This is an approvable change as it will not increase emissions and does not affect the stringency of the control requirement.

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

The State submittal has met the public notice requirements for SIP submissions in accordance with 40 CFR 51.102. The submittal also satisfied the completeness criteria of 40 CFR part 51, appendix V. In addition, as explained above and in more detail in the technical support document which is part of this document, the revision meets the substantive SIP requirements of the CAA, including section 110 and implementing regulations.

What action is EPA taking?

This action approves revision to the Missouri SIP-approved Doe Run Herculaneum Consent Judgment. The revision removes language referring to the exact bag technology while leaving the related performance standard requirements in place. We are processing this action as a direct final action because the revisions do not change performance standard requirements and are thus expected to be noncontroversial. Additionally, the revisions have gone through the Missouri approval process, including a public hearing and opportunity for public comments. EPA was the only party to provide comments during Missouri's comment period. Therefore, we do not anticipate any adverse comments. Please note that if EPA receives adverse comment on part of this rule and if that part can be severed from the remainder of the rule, EPA may adopt as final those parts of the rule that are not the subject of an adverse comment.

Statutory and Executive Order Reviews

Under Executive Order 12866 (58 FR 51735, October 4, 1993), this action is not a “significant regulatory action” and therefore is not subject to review by the Office of Management and Budget. For this reason, this action is also not subject to Executive Order 13211, “Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use” (66 FR 28355, May 22, 2001). This action merely approves state law as meeting Federal requirements and imposes no additional requirements beyond those imposed by State law. Accordingly, the Administrator certifies that this rule will not have a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.). Because this rule approves pre-existing requirements under State law and does not impose any additional enforceable duty beyond that required by State law, it 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).

This rule also does not have tribal implications because it will not have a substantial direct effect on one or more 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, as specified by Executive Order 13175 (65 FR 67249, November 9, 2000). This action also does not have Federalism implications because it does 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, as specified in Executive Order 13132 (64 FR 43255, August 10, 1999). This action merely approves a State rule implementing a Federal standard, and does not alter the relationship or the distribution of power and responsibilities established in the CAA. This rule also is not subject to Executive Order 13045, “Protection of Children from Environmental Health Risks and Safety Risks” (62 FR 19885, April 23, 1997), because it approves a State rule implementing a Federal standard.

In reviewing SIP submissions, EPA's role is to approve state choices, provided that they meet the criteria of the CAA. In this context, in the absence of a prior existing requirement for the State to use voluntary consensus standards (VCS), EPA has no authority to disapprove a SIP submission for failure to use VCS. It would thus be inconsistent with applicable law for EPA, when it reviews a SIP submission, to use VCS in place of a SIP submission that otherwise satisfies the provisions of the CAA. Thus, the requirements of section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) do not apply. This rule does not impose an information collection burden under the provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.).

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 rule 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 July 3, 2007. 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 section 307(b)(2).)
