Background

The area within the Eugene-Springfield Urban Growth Boundary was designated as a moderate PM₁₀ nonattainment area upon enactment of the Clean Air Act (CAA) Amendments of 1990.

Oregon submitted an attainment plan to EPA on November 15, 1991, as a moderate PM₁₀ State Implementation Plan (SIP) under section 189(a) of the CAA. The EPA approved the Eugene-Springfield moderate PM₁₀ SIP on August 24, 1994 (59 FR 43483 (PDF)(7 pp, 1 MB, About PDF)).

On January 13, 2012, Oregon submitted a PM₁₀ Limited Maintenance Plan and Redesignation Request. On April 11, 2013, EPA took direct final action to approve the Eugene-Springfield PM₁₀ Limited Maintenance Plan and redesignate the area to attainment for PM₁₀ (78 FR 21547 (PDF)(9 pp, 281 K)). 

Summary

The plan relies on control strategies needed to maintain attainment of the PM₁₀ National Ambient Air Quality Standards (NAAQS). The strategy focuses on mandatory home wood heating curtailment program and existing controls on local industrial sources.
