E8-17701. Approval and Promulgation of Implementation Plans; Texas; El Paso County Carbon Monoxide Redesignation to Attainment, and Approval of Maintenance Plan

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

On February 13, 2008, the Texas Commission on Environmental Quality (TCEQ) submitted a State Implementation Plan (SIP) revision to request redesignation of the El Paso carbon monoxide (CO) nonattainment area to attainment for the CO National Ambient Air Quality Standard (NAAQS). This submittal also included a CO maintenance plan for the El Paso area and associated Motor Vehicle Emission Budgets (MVEBs). The maintenance plan was developed to ensure continued attainment of the CO NAAQS for a period of 10 years from the effective date of EPA approval of redesignation to attainment. In this action, EPA is proposing to approve the El Paso CO redesignation request and the maintenance plan with its associated MVEBs as satisfying the requirements of the Federal Clean Air Act (CAA) as amended in 1990.

SUPPLEMENTARY INFORMATION:

I. Why is EPA issuing this proposed rule?

This document proposes to take action on SIP revisions pertaining to the El Paso area. We have published a direct final rule approving the State's SIP revisions in the “Rules and Regulations” section of this Federal Register because we view this as a noncontroversial action and anticipate no adverse comment. We have explained our reasons for this action in the preamble to the direct final rule.

If we receive no relevant adverse comment, we will not take further action on this proposed rule. If we receive relevant adverse comment, we will withdraw the direct final rule and it will not take effect. We would address all public comments in any subsequent final rule based on this proposed rule.

We do not intend to institute a second comment period on this action. Any parties interested in commenting must do so at this time. For further information, please see the information provided in the ADDRESSES section of this document.
