Ambient Air Quality Surveillance and Designation of Areas for Air Quality Planning Purposes; Louisiana; Modification of Ozone Monitoring Season and Revisions to Geographical Boundaries of Air Quality Control Regions

摘要

The EPA is taking direct final action to revise the geographical boundaries of the three Air Quality Control Regions (AQCRs) in the State of Louisiana, which are the Southern Louisiana- Southeast Texas AQCR, the Shreveport-Texarkana-Tyler AQCR, and the Monroe-El Dorado AQCR. The EPA is also taking direct final action to shorten the ozone season for the Monroe-El Dorado and Shreveport- Texarkana-Tyler AQCRs, from year-round, to March 1 through October 31. EPA is taking this action in response to a June 12, 1995, letter from the Governor of Louisiana requesting that EPA revise the AQCR boundaries and ozone seasons in order to provide for more effective and efficient air quality management in the State of Louisiana.
