Proposed State Implementation Plan Revision
Wallula PM10 Nonattainment Area
The United States Environmental Protection Agency (EPA) has set an air quality standard for particulate matter ten micrometers or less in size (PM10) to protect public health. When an area in Washington does not meet this air quality standard, EPA formally designates the area "nonattainment." Ecology is required by the Clean Air Act to develop a plan to meet the standard.
The Clean Air Act allows EPA to redesignate a nonattainment area to attainment once certain conditions have been met. These conditions include the following:
|•||Monitoring data that shows attainment of the PM10 standard.|
|•||Full EPA approval of the plan to meet the standard.|
|•||Fulfillment of any additional SIP requirements.|
|•||Permanent and enforceable reductions in PM10 emissions.|
|•||An EPA-approved maintenance plan that provides for continued attainment of the PM10 standard for ten years after redesignation to attainment.|
EPA proposed approval of the attainment plan in the February 1, 2005, Federal Register. Controls on emissions in place in the nonattainment area include a new permit for the beef cattle processing facility, paving of a haul road at the pulp and paper mill, a fugitive dust control plan for the associated compost facility, and a fugitive dust control plan for the beef cattle feedlot.
The SIP revision also includes the maintenance plan. This plan includes the following major elements:
• A 2002 inventory of PM10 emissions that shows the level of emissions compatible with attainment of the PM10 standard (over 50% of the emissions come from agricultural tilling, and almost 40% come from large and small industrial sources).
|•||A demonstration that the PM10 standard will be maintained through 2015.|
|•||A contingency plan that provides for: (1) Improved monitoring; (2) use of continuous monitoring to evaluate maintenance of the standard; and (3) continued implementation of Best Available Control Measures to deal with windblown dust from agricultural fields (with a single exception, exceedances in the Wallula area the result of windblown dust).|
