The Environmental Protection Agency (EPA) is proposing to approve elements of a State Implementation Plan (SIP) revision from the State of Missouri for the 2010 Nitrogen Dioxide (NO<INF>2</INF>) National Ambient Air Quality Standard (NAAQS). Section 110 of the CAA requires that each state adopt and submit a SIP for the 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. In the "Rules and Regulations" section of this issue of the Federal Register, we are approving the state's SIP revisions as a direct final rule without a prior proposed rule. If we receive no adverse comment, we will not take further action on this proposed rule.
The agency’s own summary, as published.
