## Abstract

The USEPA approves the State Implementation Plan (SIP) revision request submitted by the State of Indiana on August 25, 1995, establishing a summertime gasoline Reid Vapor Pressure (RVP) limit of 7.8 pounds per square inch (psi) for gasoline distributed in Clark and Floyd Counties, as part of the State's plan to attain 15 percent (%) Reasonable Further Progress (RFP) reductions of Volatile Organic Compounds (VOC) emissions in these two Counties by 1996. Emissions of VOC react with other pollutants, such as oxides of nitrogen, on hot summer days to form ground-level ozone, commonly known as smog. Ozone pollution is of particular concern because of its harmful effects upon lung tissue and breathing passages. RFP plans are intended to bring areas which have been exceeding the public health-based Federal ozone air quality standard closer toward the goal of attaining and maintaining this standard. Indiana expects that the summertime RVP gasoline limit will reduce VOC emissions by 2.29 tons per day in the Clark and Floyd Counties ozone nonattainment area. A final approval action is being taken because the submittal meets all pertinent Federal requirements.
