The National Shipbuilding Program. Preliminary Impact Analysis of Proposed Revisions of National Ambient Air Quality Standard for Ozone and Particulate Matter
Abstract
This report documents a preliminary analysis of the potential long term impacts on shipyards of proposed revisions to the National Ambient Air Quality Standards (NAAQS) for ozone (03) and particulate matter (PM). The analysis was performed to provide information to the U.S. ship building and ship repair industry, so that companies in that industry could determine whether to submit comments on these EPA proposals. Project results were also presented to NSRP SP-1 panel partcipants at a quarterly panel meeting in February, 1997. Revised NAAQS are the first step in the air regulatory process. In some cases, new regulations based on revised NAAQS may be in place in as little at four or five years. However, EPA has estimated that it may take 10 to 15 years before programs based on revised NAAQS are "fully implemented." This project addresses the potential impacts of these downstream implementation measures. The U.S. EPA has reviewed existing NAAQS for 03 and PM as required by sections 108 and 109 of the Clean Air Act (Act). Based on these reviews, the EPA proposes to change the standards for both classes of pollutants. 1' With respect to 03, EPA proposes to change the current primary standard (last modified in 1979) in the following manner.
