AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Direct final rule.

SUMMARY:

The EPA is taking direct final action on a request to redesignate Grant County, New Mexico from nonattainment area to attainment for the sulfur dioxide (SO₂) National Ambient Air Quality Standards (NAAQS). In conjunction with this action, EPA is also approving the maintenance plan, and its associated contingency measures plan for the Grant County nonattainment area, which were submitted to ensure that the attainment of SO₂ NAAQS will continue to be maintained. The redesignation request and maintenance and contingency measures plans were submitted as a revision to the New Mexico State Implementation Plan (SIP) by the New Mexico Environment Department (NMED) on February 21, 2003. We are approving these revisions in accordance with the requirements of the Federal Clean Air Act (Act).

DATES:

This rule is effective on November 17, 2003 without further notice, unless EPA receives relevant adverse comment by October 20, 2003. If EPA receives such comment, EPA will publish a timely withdrawal in the Federal Register informing the public that this rule will not take effect.

Final Action

General Information

Statutory and Executive Order Reviews

Throughout this document “we,” “us,” and “our” means EPA.

A. What Action Is EPA Taking?

The EPA designated Grant County, New Mexico as nonattainment for violating the secondary SO₂ NAAQS on March 3, 1978, at 43 FR 9016. On September 11, 1978, at 43 FR 40428, EPA designated Grant County, New Mexico as nonattainment for violating the primary SO₂ NAAQS. Any area designated as not attaining the primary or secondary SO₂ NAAQS as of the date of enactment of the 1990 Amendments was designated nonattainment for SO₂ by operation of law upon enactment, pursuant to section 107(d)(1)(C)(i) of the Act (April 22, 1991, at 56 FR 16274).

On February 21, 2003, the Governor of New Mexico submitted to us a revision to the New Mexico SO₂ SIP (February 21, 2003 submittal). The February 21, 2003 submittal specifically requested EPA to redesignate the portion of Grant County, New Mexico, located in the Air Quality Control Region (AQCR) No. 021, from nonattainment to attainment for the SO₂ NAAQS. This particular portion of Grant County is restricted to a 3.5 mile radius around the Kennecott Copper Corporation (now owned by the Phelps Dodge Corporation and called the Hurley smelter) and land above 6470 feet Mean Sea Level within an 8 mile radius of the Hurley Smelter in Hurley, New Mexico. The air monitoring data for this area reveals values better than national standards for SO₂. The February 21, 2003, submittal also included a maintenance plan for this area to ensure that attainment of the SO₂ NAAQS will be maintained through permitting and the applicable SIP rules. The State also submitted a contingency measures plan that consists of monitoring measures.

In this document we are approving NMED's request to redesignate the Grant County primary and secondary SO₂ nonattainment areas to attainment of the SO₂ NAAQS. We are also approving the maintenance plan and the contingency measures plan for this area into the New Mexico SO₂ SIP. See our Technical Support Document (TSD) for additional information and our evaluation of this submittal.

B. Why Was This SIP Revision Submitted?

The NMED believes that the Grant County area is now eligible for redesignation because EPA approved New Mexico's SIP in 1982, and the SO₂ monitors in the nonattainment area of Grant County have not recorded exceedances of either the primary or secondary SO₂ NAAQS since 1979.

C. What Is the NAAQS for SO₂?

Under section 109 of the Act, EPA established the NAAQS to protect public health and welfare. The NAAQS address 6 criteria pollutants, which are carbon monoxide, nitrogen dioxide, ozone, lead, particulate matter, and sulfur dioxide (SO₂).

High concentrations of SO₂ affect breathing and may aggravate existing respiratory and cardiovascular disease. Sensitive populations include asthmatics, individuals with bronchitis or emphysema, children and the elderly. SO₂ is also a primary contributor to acid deposition or acid rain, which causes acidification of lakes and streams and can damage trees, crops, historic buildings and statues. In addition, sulfur compounds in the air contribute to visibility impairment in large parts of the country. This is especially noticeable in national parks.

Ambient SO₂ results largely from stationary sources such as coal and oil combustion, steel mills, refineries, pulp and paper mills and from nonferrous smelters. There are 3 NAAQS for SO₂:

—An annual arithmetic mean of 0.03 ppm (80 ug/m³);

—A 24-hour level of 0.14 ppm (365 ug/m³); and

—A 3-hour level of 0.50 ppm (1300 ug/m³).

The first two standards are primary (health-related) standards, while the 3-hour NAAQS is a secondary (welfare-related) standard. The annual mean standard is not to be exceeded, while the short-term standards are not to be exceeded more than once per year. Our TSD contains the ambient SO₂ monitored values for the Grant County, New Mexico nonattainment area.

D. What Is a SIP?

Section 110 of the Act requires states to develop air pollution regulations and control strategies to ensure that state air quality meets the NAAQS that EPA has established.

Each state must submit these regulations and control strategies to us for approval and incorporation into the federally enforceable SIP. Each federally approved SIP is designed to protect air quality. These SIPs can be extensive, containing state regulations or other enforceable documents and supporting information such as emission inventories, monitoring networks, and modeling demonstrations.

E. What Is the Federal Approval Process for a SIP?

When a state wants to incorporate its regulations into the federally enforceable SIP, the state must formally adopt the regulations and control strategies consistent with state and Federal requirements. This process includes a public notice, a public hearing, a public comment period, and a formal adoption by a state-authorized rulemaking body.

Once a state adopts a rule, regulation, or control strategy, the state may submit the adopted provisions to us and request that we include these provisions in the federally enforceable SIP. We must then decide on an appropriate Federal action, provide public notice on this action, and seek additional public comment regarding this action. If we receive relevant adverse comments, we must address them prior to taking a final action.

Under section 110 of the Act, when we approve all state regulations and supporting information, those state regulations and supporting information become a part of the federally approved SIP. You can find records of these SIP actions in the Code of Federal Regulations (CFR) at Title 40, part 52, entitled “Approval and Promulgation of Implementation Plans.” The actual state regulations that we approved are not reproduced in their entirety in the CFR but are “incorporated by reference,” which means that we have approved a given state regulation with a specific effective date.

F. What Does Federal Approval of a SIP Mean to Me?

A state may enforce state regulations before and after we incorporate those regulations into a federally approved SIP. After we incorporate those regulations into a federally approved SIP, both EPA and the public may also take enforcement action against violators of these regulations.

G. What Requirements Must the State Meet for Approval of a Redesignation and How Did the State Meet Them?

1. The State Must Show That the Area Is Attaining the Applicable NAAQS

An area is considered to be in attainment of the SO₂ NAAQS provided that the primary and secondary standards have not been violated within the last three years. Grant County has had two monitors in place that have shown no violations since 1997; these monitors are in Bayard, NM and Hurley, NM. The monitor in Bayard has been in place since 1974 (and has shown no violations since 1979) and the monitor in Hurley has been in place since 1997. These monitors meet the requirements of 40 CFR Parts 53 and 58.

The monitor in Hurley is located in the area of highest concentration for SO₂ within the nonattainment area, as studied by the EPA Regional Office and NMED before deployment of the monitor in 1997. The monitor was placed where modeling indicated the highest concentration was likely to occur. As a result of this modeling, NMED does not have to submit additional material reproving that the data is representative of the point of highest concentration in the nonattainment area.

2. The SIP for the Area Must Be Fully Approved Under Section 110(k) of the Act and Must Satisfy All Requirements That Apply to the Area

The Grant County SO₂ SIP revision was approved by EPA on May 5, 1982 (47 FR 19332) and contained limits pertaining to the sole source of SO₂, the Hurley Smelter. The EPA approved changes to New Mexico's SO₂ plan for Grant County on September 26, 1997 (62 FR 50514).

3. The EPA Has Determined That the Improvement in Air Quality Is Due to Permanent and Enforceable Reductions in Emissions

Air quality improvement in the Grant County SO₂ nonattainment area is attributed to the SO₂ emission limits in the SIP and to the operating restrictions within the Title V permit imposed on the facility that contributed to the nonattainment status. Reductions in emissions are therefore permanent and enforceable.

4. The State Has Met All Applicable Requirements Under Section 110 and Part D of the Act That Were Applicable Prior to Submittal of the Complete Redesignation Request

The requirements under Section 110 and Part D are met with the prior approval of the SIP revisions for the source in the area in 1982, the approval of revisions in 1997 (62 FR 50514), and with the detailed study of the modeling generated by the NMED in 1997.

5. EPA Is Fully Approving a Maintenance Plan, Including a Contingency Plan, for the Area Under Section 175A of the Act

Maintenance Plan

Section 175A of the Act requires states to submit a SIP revision which provides for the maintenance of the NAAQS in the area for at least 10 years after approval of the redesignation. The basic components needed to ensure proper maintenance of the NAAQS are: attainment inventory, maintenance demonstration, verification of continued attainment, ambient air monitoring network, and a contingency plan.

a. Attainment Inventory

The state's submittal contains the emission inventory of SO₂ sources in the Grant County nonattainment area, dating back to 1997. It clearly shows that Grant County has not exceeded the SO₂ NAAQS since 1997.

b. Maintenance Demonstration and Verification of Continued Attainment

Maintenance of the SO₂ NAAQS in the Grant County nonattainment area has been achieved through the SIP and Title V permit requirements. The SO₂ emitting source involved in the Grant County SO₂ redesignation (the Hurley Smelter) is meeting the SO₂ emission limits identified in the SIP rules and permit. NMED will track the maintenance plan through the semi-annual review of permit conditions, air emission inventory and state regulations 20.2.41 NMAC and 20.2.3 NMAC which verify that the State of New Mexico has the continued legal authority needed to implement and enforce air quality controls to maintain the SO₂ NAAQS in Grant County.

c. Monitoring Network

After a detailed study of the modeling generated by the NMED in 1997 for placement of a new monitor in the Grant County nonattainment area, the Regional Office determined (in a letter to NMED dated August 26, 2002) that “the monitor was placed where modeling indicated the highest concentration was likely to occur.” A copy of this letter is being attached to our TSD for reference purposes. Therefore, the NMED will use the current SO₂ air monitoring station located in Hurley, New Mexico to verify continuing attainment of the NAAQS in the area. The Hurley monitoring station meets 40 CFR Part 58. The SO₂ monitoring station located in Bayard, New Mexico will be discontinued.

d. Contingency Plan

Section 175A of the Act requires that the maintenance plan include contingency provisions to correct any violation of the NAAQS after redesignation of the area. However, the General Preamble for the Implementation of Title I of the Act Amendments of 1990 (57 FR 13498) states that SO₂ provisions require special considerations. A primary reason is that SO₂ control methods are well established and understood. Therefore, contingency measures for SO₂ need only consist of a comprehensive program to identify sources of violations of the SO₂ NAAQS and to undertake an aggressive follow-up for compliance and enforcement.

Upon verification of a violation of either the 24-hour or 3-hour SO₂ NAAQS, if the Hurley Smelter is responsible for the violation, NMED will work with this source to ensure that the violation will not occur again. If necessary, NMED will write and adopt rules or amend the company's Title V permit to control SO₂ emissions at the company.

The State will be utilizing both the currently approved SIP requirements and Title V permit as tools for implementation of SO₂ Maintenance Plan. The State will be utilizing both Title V reporting, testing, compliance certification, and recordkeeping controls combined with the Continuous Emission Monitoring System (CEMS) data for SO₂ emissions as its Contingency Plan. It is EPA's finding that these reporting, testing, compliance certification, recordkeeping controls and the CEMS data requirements are a comprehensive program for identifying violations caused by the smelter. The February 21, 2003 submittal does not propose to remove or relax any of the existing SIP approved measures for controlling SO₂ emissions. A new major source of SO₂ or an existing source with major modification, including a process that may have been shut down or ceased operation, will not only have to comply with the existing federally approved SO₂ SIP provisions, it will also need to comply with terms and conditions that may be more stringent than existing SIP requirements imposed on the source in its air permit to ensure the area will continue maintaining the attainment status.

As detailed above, the State has met the maintenance plan requirements of Section 175A of the Act and the maintenance plan is fully approvable. The contingency measures plan is also fully approvable.

Final Action

We have evaluated the State's submittal and have determined that it meets the applicable requirements of the Act, and EPA regulations, and conforms to EPA policy. Therefore, we are approving the State of New Mexico's request to redesignate Grant County from a primary and secondary SO₂ nonattainment area to an SO₂ NAAQS attainment area. We are also approving the maintenance and contingency measures plans for Grant County into the New Mexico SIP. Furthermore, we are approving the NMED's request to discontinue the current SO₂ monitoring in Bayard, NM.

The EPA is publishing this rule without prior proposal because we view this as a noncontroversial amendment and anticipate no relevant adverse comments. However, in the “Proposed Rules” section of today's Federal Register publication, we are publishing a separate document that will serve as the proposal to approve the Maintenance Plan if relevant adverse comments are received. This rule will be effective on November 17, 2003 without further notice unless we receive relevant adverse comment by October 20, 2003. If EPA receives relevant adverse comments, we will publish a timely withdrawal in the Federal Register informing the public that the rule will not take effect. We will address all public comments in a subsequent final rule based on the proposed rule. We will not institute a second comment period on this action. Any parties interested in commenting must do so at this time.

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 (Public Law 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 Clean Air Act. 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 is not economically significant.

In reviewing SIP submissions, EPA's role is to approve state choices, provided that they meet the criteria of the Clean Air Act. 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 Clean Air Act. 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. section 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. section 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 November 17, 2003. 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).)
