| 02-32384 | National Ambient Air Quality Standard: Particulate Matter | Rule | The EPA is taking direct final action to amend the national ambient air quality standards for particulate matter. The revision reduces to 15 percent the requirement that reporting organizations collocate 25 percent of State and local air monitoring station (SLAMS) sites with a second sampler in order to estimate precision at a reporting organization level. The regulations describe the number of collocated sites required within a reporting organization. With today's action, EPA is making a simple change in the regulations by changing the requirement to collocate 25 percent of reporting organizations sites to 15 percent of the reporting organizations sites. The effect of this change will be to reduce the number of monitors which must be collocated. This in turn will reduce the cost of implementing and maintaining monitoring networks but without significantly affecting our confidence in the precision at the reporting organization level or in providing acceptable estimates of achievement of the precision Data Quality Objectives (DQOs). Since reporting organizations are of unequal size in the number of monitors they implement, 15 percent was considered an acceptable limit of providing enough precision information for smaller reporting organizations while not unduly burdening larger reporting organizations. | 2002-12-31 | 2002 | 12 | https://www.federalregister.gov/documents/2002/12/31/02-32384/national-ambient-air-quality-standard-particulate-matter | https://www.govinfo.gov/content/pkg/FR-2002-12-31/pdf/02-32384.pdf | Environmental Protection Agency | 145 | The EPA is taking direct final action to amend the national ambient air quality standards for particulate matter.
