Description:
Section 182 (c) (1) of the 1990 Clean Air Act Amendments requires the EPA Administrator to promulgate rules for the enhanced monitoring of ozone, oxides of nitrogen and volatile organic compounds to obtain more comprehensive and representative data on ozone air pollution. he Subsequent revisions to Title 40 Code of Federal Regulations, Part 58 (40CFR58) require States to establish Photochemical Assessment Monitoring Stations (PAMS) as part of their SIP monitoring networks in ozone nonattainment areas classified as serious, severe, or extreme. The primary objective of the enhanced ozone monitoring revisions is to provide an air quality data base that will assist air pollution control agencies in evaluating, tacking the progress of, and, if necessary, refining control strategies for attaining the ozone National Ambient Air Quality Standard (NAAQS). pecific provisions of the rule require the establishment and operation of up to 5 PAMS in each affected area, depending on population. ach station will sample for speciated volatile organic compounds (VOC) including several carbonyls, ozone, oxides of nitrogen, and surface meteorological parameters. This lecture will review these requirements, the technical assistance document that provides specific monitoring guidance, and the emerging continuous V0C measuring techniques that are currently being used to support this program. he design and results of an automated gas chromatography demonstration/experiment conducted at Research Triangle Park, N.C. during of September 1992 will be discussed. The five commercially available automated GC systems that were evaluated during this experiment will be described.
