| E9-6178 | Methods for Measurement of Filterable PM10 and PM2.5 and Measurement of Condensable Particulate Matter Emissions From Stationary Sources | Proposed Rule | This action proposes amendments to Methods 201A and 202. The proposed amendments to Method 201A would add a particle-sizing device to allow for sampling of particulate matter (PM) with mean aerodynamic diameters less than or equal to 2.5 micrometers ([mu]m) (PM<INF>2.5</INF> or fine PM). The proposed amendments to Method 202 would revise the sample collection and recovery procedures of the method to reduce the formation of reaction artifacts that could lead to inaccurate measurements of condensable particulate matter (CPM). Additionally, the proposed amendments to Method 202 would eliminate most of the hardware and analytical options in the existing method, thereby increasing the precision of the method and improving the consistency in the measurements obtained between source tests performed under different regulatory authorities. Finally, in this notice we are soliciting comments on whether to end the transition period for CPM in the New Source Review (NSR) program on a date earlier than the current end date of January 1, 2011. The proposed amendments would improve the measurement of fine particulates and would help State and local agencies in implementing CPM control measures to attain the PM<INF>2.5</INF> National Ambient Air Quality Standards (NAAQS) which were established to protect public health and welfare. | 2009-03-25 | 2009 | 3 | https://www.federalregister.gov/documents/2009/03/25/E9-6178/methods-for-measurement-of-filterable-pm10-and-pm25-and-measurement-of-condensable-particulate | https://www.govinfo.gov/content/pkg/FR-2009-03-25/pdf/E9-6178.pdf | Environmental Protection Agency | 145 | This action proposes amendments to Methods 201A and 202.
