Air Plan Approval; New Mexico; Infrastructure for the 2015 Ozone National Ambient Air Quality Standards and Repeal of State Regulations for Total Suspended Particulate

Pursuant to the Federal Clean Air Act (CAA or the Act), the Environmental Protection Agency (EPA) is approving State Implementation Plan (SIP) infrastructure certifications from the State of New Mexico and Albuquerque-Bernalillo County to address CAA section 110(a)(1) and (2) requirements for the 2015 ozone (O<INF>3</INF>) National Ambient Air Quality Standards (NAAQS). The submittals address how the existing SIP provides for the implementation, maintenance, and enforcement of the 2015 O<INF>3</INF> NAAQS (infrastructure SIP or i-SIP). The i-SIP ensures that the New Mexico SIP is adequate to meet the state's responsibilities under the CAA for this NAAQS. The EPA is also approving a SIP revision for the repeal of the New Mexico Ambient Air Quality Standards (NMAAQS) for total suspended particulate (TSP) in the New Mexico regulations incorporated into the SIP.
