| 2010-30847 | Methods for Measurement of Filterable PM10 and PM2.5 and Measurement of Condensable PM Emissions From Stationary Sources | Rule | This action promulgates amendments to Methods 201A and 202. The final amendments to Method 201A add a particle-sizing device to allow for sampling of particulate matter with mean aerodynamic diameters less than or equal to 2.5 micrometers (PM<INF>2.5</INF> or fine particulate matter). The final amendments to Method 202 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. Additionally, the final amendments to Method 202 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. This action also announces that EPA is taking no action to affect the already established January 1, 2011 sunset date for the New Source Review (NSR) transition period, during which EPA is not requiring that State NSR programs address condensable particulate matter emissions. | 2010-12-21 | 2010 | 12 | https://www.federalregister.gov/documents/2010/12/21/2010-30847/methods-for-measurement-of-filterable-pm10-and-pm25-and-measurement-of-condensable-pm-emissions-from | https://www.govinfo.gov/content/pkg/FR-2010-12-21/pdf/2010-30847.pdf | Environmental Protection Agency | 145 | This action promulgates amendments to Methods 201A and 202.
