Approval and Promulgation of Implementation Plans Tennessee: Approval of Revisions to Nashville-Davidson Regulation Number 3: New Source Review

Summary

The US Environmental Protection Agency (EPA) granted limited approval to revisions in the Nashville-Davidson County portion of the Tennessee State Implementation Plan (SIP) to align with New Source Review (NSR) requirements and Prevention of Significant Deterioration (PSD) increments for nitrogen dioxide (NO2). The revisions do not fully meet the NSR requirements of the Clean Air Act but strengthen the SIP overall.
