Summary of La Grande PM-10 Attainment Plan
Background
The Union County, LaGrande, Oregon, Urban Growth Boundary was designated nonattainment for PM10 and classified as moderate upon enactment of the Clear Air Act Amendments in 1990.
Oregon submitted a PM10 attainment plan on November 15, 1991 and EPA proposed the plan on July 1, 1994 (59 FR 33914 (pdf) (360 KB)).
On February 15, 1995, EPA approved the LaGrande PM10 attainment plan (60 FR 8563 (pdf) (121 KB)).
On November 5, 1999, Oregon submitted a complete rule renumbering and relabeling package to EPA for approval in the SIP. On January 22, 2003, EPA approved the recodified version of Oregon's rules to remove and replace the outdated numbering system (68 FR 2891 (pdf) (204 KB)). The following list refers to the currently approved SIP rules.
Summary
The plan relies on control strategies needed to assure attainment of the PM10 National Ambient Air Quality Standards (NAAQS). The strategy focuses on control of residential wood combustion, fugitive dust and industrial emissions. Other strategies include progressive programs to further reduce fugitive dust and woodburning emissions.
