NOTICE: RULES

ACTION: Air quality implementation plans; approval and promulgation; various States:

DOCUMENT ACTION: Final rule.

SUBJECT CATEGORY:

Approval and Promulgation of Implementation Plans; Texas; Permitting of New and Modified Sources in Nonattainment Areas

EFFECTIVE DATES: This rule is effective on August 16, 2000.

DOCUMENT SUMMARY:

The EPA is approving revisions to the Texas State Implementation Plan (SIP) for the permitting of new major sources and major modifications in areas which do not meet the national ambient air quality standards (NAAQS) promulgated by EPA (nonattainment areas). The EPA is approving these revisions to satisfy the provisions of the Clean Air Act (Act) which relate to the permitting of new and modified sources which are located in nonattainment areas. Today's action approves the recodification of and revisions to the nonattainment permitting regulations. Today's action also approves revisions relating to when nonattainment area permitting requirements apply to emissions of nitrogen oxides (NOX) as a precursor to ozone in an ozone nonattainment area.

SUMMARY:

I. What Action Are We Taking?

We are finalizing our approval of the recodification of and revisions to Title 30, Texas Administrative Code (TAC) Chapter 116, ``Control of Air Pollution by Permits for New Construction or Modification,'' as indicated in Table 1 below:
Table 1.Regulations That EPA Is Approving Recodified section of 30 TAC chapter Submittal dates of recodified 116 section Title or description Former section of 30 TAC chapter 116 Section 116.12........................

This proposal includes portions of revisions submitted by the Governor of Texas to EPA on the following dates:

  • August 31, 1993.
  • November 1, 1995.
  • July 18, 1996.
  • April 13, 1998.
  • March 16, 1999.
    We are taking this rulemaking action under sections 110, 301 and part D of the Act. We are acting only on those parts of these submittals which relate to permitting sources in nonattainment areas.

    II. What Is the Background for This Action?

    On January 18, 2000, we published a notice of proposed rulemaking (NPR) proposing full approval of the recodification of and revisions to Texas' regulations for the permitting of new major sources and major modifications in nonattainment areas. The Governor submitted revisions to these nonattainment area permitting requirements as described above.

    As explained in the NPR, we have determined that Texas' recodification of and revisions to its nonattainment permitting requirements continue to meet the requirements of part D of the Act and 40 CFR 51.165 (Permit Requirements). The NPR provided opportunity for the public to comment on the proposed action. The public comment period for our action ended February 17, 2000. We received no comments on the NPR. As a result, we are finalizing our proposed approval without changes. For more details on these submittals, please refer to the proposed rulemaking.

    IV. What Are the Federal Requirements for Permitting Major Sources and Major Modifications in Nonattainment Areas?
    A. What Are the Statutory Requirements for Permitting Major Sources and Major Modifications in Nonattainment Areas?

    The statutory requirements governing permitting in nonattainment areas are in part D of the Act. Specifically, the Act requires that a major source or major modification meet the criteria in Table 3 below. Table 3.Summary of Requirement for Permitting Major Sources and Major Modifications in Nonattainment Areas Requirement of Act Where specified in the Act Citation in state regulations Base emissions offsets on the Section 173(a)(1)(A)................

    B. Who Is Affected by This Action?

    The requirements described in Table 3 above apply to each owner and/or operator who constructs or modifies a stationary source in a nonattainment area in Texas if the stationary source is major for the air pollutant for which the area is nonattainment. A stationary source is major if it emits, or has the potential to emit, the nonattaining pollutant, or precursor thereto, in amounts greater than the major source threshold for the nonattaining pollutant.
    C. What Are the Major Source Thresholds for Nonattainment Pollutants?

    The major source threshold varies, depending on the pollutant and the classification of the nonattainment area. Any owner or operator who proposes to construct a major stationary source must obtain a permit which complies with the regulations that we are approving herein. Table 4 below lists the major source threshold for each pollutant. Table 4.Major Source Thresholds Pollutant: classification Major source threshold in tons per year (TPY) Where specified in the Act Ozone:

    Marginal.................. 100 of volatile organic compounds (VOC) or NOX....................................... Section 302(j).

    Moderate.................. 100 of VOC or NOX.................................................................... Section 302(j).

    Serious................... 50 of VOC or NOX..................................................................... Section 182(c).

    Severe.................... 25 of VOC or NOX..................................................................... Section 182(d). [[Page 43989]]

    Carbon monoxide (CO):

    Moderate.................. 100.................................................................................. Section 302(j).

    Serious................... 50................................................................................... Section 187(c)(1). Particulate matter less than

    10 micrometers (PM10):

    Moderate.................. 100.................................................................................. Section 302(j).

    Serious................... 70................................................................................... Section 189(b)(3).

NOX........................... 100.................................................................................. Section 302(j). Lead.......................... 100.................................................................................. Section 302(j).

    Table 4 above refers to classifications for areas designated nonattainment for ozone, CO, and PM10. These nonattainment classifications are defined in the Act as follows:

  • Section 181(a) defines five area classifications for ozone. These five classifications are marginal, moderate, serious, severe, and extreme. Texas has no extreme ozone nonattainment areas and does not address such areas in its regulations.
  • Section 186(a) defines two area classifications for CO. These two classifications are moderate and serious.
  • Section 188 defines two area classifications for PM10. These two classifications are moderate and serious.

    A detailed description of the individual area classifications for ozone, CO, and PM10 nonattainment areas is contained in EPA's General Preamble for the Implementation of Title I of the 1990 Amendments, 57 FR 13498 (April 16, 1992).

    D. What Is a Major Modification?

    A major modification is any physical change, or change in the method of operating, a major stationary source which significantly increases net emissions of the air pollutant, or precursor, for which the area is nonattainment and for which the source is a major source before the modification.

    Any owner or operator who proposes a major modification must obtain a permit that complies with the regulations that we are approving herein. Table 5 below lists the significance level for each pollutant which is used in determining whether a net emissions increase is a major modification.
    Table 5.Significance Levels for Major Modifications Pollutant: Classification Significance level in TPY Where specified in the Act or regulations Ozone:

    Marginal................. 40 of VOC or NOX............... 40 CFR 51.165(a)(x).

    Moderate................. 40 of VOC or NOX............... 40 CFR 51.165(a)(x).

    Serious.................. 25 of VOC or NOX............... Section 182(c)(6) of the Act.

    Severe................... 25 of VOC or NOX............... Section 182(c)(6) of the Act.
