    I. Background

    On July 3, 2024 (89 FR 55136), the EPA published a Notice of Proposed Rulemaking (NPRM) for the State of New Mexico. The NPRM proposed approval of the state's periodic emissions inventory for Sunland Park, Doña Ana County, New Mexico marginal nonattainment area for the 2015 NAAQS. The background for this action and rationale for EPA's proposed action are explained in the NPRM and will not be restated here. We received a comment on our proposal from the New Mexico Environmental Department (NMED). Our response to the comment follows.

    II. Response to Comments

    We received one comment from the NMED regarding an inadvertent typographical error in the NPRM—in tables 1 and 2 that summarized the NOX and VOC emissions in Sunland Park, Doña Ana County, New Mexico. The ozone season daily emissions (lb/day) column in the NPRM showed some discrepancies from what was submitted by the State. In response, the EPA is making the necessary corrections in the updated tables 1, and 2 listed below. The corrected values in fact are less than what was previously listed in tables 1 and 2 of the proposed action. This correction does not change or affect the total NOX or VOC emissions in the 2020 periodic emission inventory for Sunland Park marginal nonattainment area for a typical ozone season day. Additionally, the original tables were included in the State's SIP revision submittal, in the rulemaking docket.

    A copy of the SIP revision is available online at www.regulations.gov, Docket number EPA-R06-OAR-2023-0648.
