Approval and Promulgation of Air Quality Implementation Plans; State of New Mexico; Infrastructure SIP Requirements for the 2008 Lead National Ambient Air Quality Standard and Repeal of Cement Kilns Rule

Resumo

The Environmental Protection Agency (EPA) is proposing to approve elements of a State Implementation Plan (SIP) submission from the State of New Mexico addressing the applicable requirements of Clean Air Act (CAA) section 110 for the 2008 National Ambient Air Quality Standards (NAAQS) for Lead (Pb), which requires that each state adopt and submit a SIP to support implementation, maintenance, and enforcement of each new or revised NAAQS promulgated by EPA. These SIPs are commonly referred to as "infrastructure" SIPs. The infrastructure requirements are designed to ensure that the structural components of each state's air quality management program are adequate to meet the state's responsibilities under the CAA. Additionally, we are proposing to approve a revision to the New Mexico SIP that repeals an existing state-wide cement kilns rule.
