Supplementary Guidelines for Lead Implementation Plans: Updated Projections for Motor Vehicle Lead Emissions

摘要

The document is an update to 'Supplementary Guidelines for Lead Implementation Plans Updated Projections for Motor Vehicle Lead Emissions,' U.S. EPA, EPA-450/2-83-002, Research Triangle Park, North Carolina, March 1983. (PB 84-104603). This document provides updated projections for automotive lead emissions to be used by those agencies developing State Implementation Plans for lead. It has been revised to include estimates of travel fractions and fleet characterizations from the June 1984 EPA report, 'User's Guide to MOBILE3 (Mobile Source Emissions Model),' EPA 460/3-84-002. (PB 84 213974). It also reflects the final rulemaking recently issued by EPA which requires refiners to lower the lead content of leaded gasoline to 0.5 g/gallon on July 1, 1985 and 0.1 g/gallon by January 1, 1986 (Federal Register, Vol. 50, No. 45, March 7, 1985).
